Conduction inspection of the coated wire can be performed. In other words, the continuity test of the coated electric wire is performed in the state of being wired to the electric wire wiring board without removing the coated electric wire wired to the electric wire wiring board from the electric wire routing board. Can.

  Therefore, at the time of the continuity inspection, it is possible to omit the process of removing the coated wire disposed on the wiring layout board from the wiring layout board and attaching it to the continuity inspection board, thereby improving the efficiency of the continuity inspection. can do. In addition, since it is not necessary to transfer the coated wire, it is possible to prevent damage to the coated wire which may occur when the coated wire is transferred.

As an aspect of the present invention, a moving mechanism may be provided to move at least one of the wire wiring board and the conduction inspection board so that the wiring board and the conduction inspection board face each other.

Moreover, the concept also includes the case where faces face each other with a constant distance, in addition to the case where a part of the faces and the whole face face each other.

  The above-mentioned movement refers to relative movement between the wire wiring board and the continuity inspection board, for example, while the surfaces of the wire wiring board and the continuity inspection board maintain a predetermined interval. The electric wire distribution board and the electric connection inspection board when the conductive inspection board moves in parallel relative to the electric wire wiring board while maintaining a predetermined distance, It is a concept including the case where it translates relatively while changing the interval with the continuity inspection board.

According to the present invention, the operation of arranging the coated electric wire on the electric wire wiring board can be performed easily and efficiently.
Specifically, for example, after laying the covered wire on the wire wiring board located at a distance from the conduction inspection board, by moving at least one of the electric wire wiring board or the conduction inspection board The connector and the continuity inspection device can be brought close to each other. That is, the covered wire is laid out at a place where the conduction inspection board does not get in the way, and after wiring is completed, at least one of the electric wire wiring board or the conduction inspection board is moved. And the continuity inspection device can be closely connected to each other. Therefore, the wiring operation of the said covered electric wire can be performed easily and efficiently.

Further, as an aspect of the present invention, it is possible to provide a facing movement mechanism that moves at least one of the electric wire wiring board and the continuity inspection board in a direction in which the electric wire wiring board and the continuity inspection board face each other.
The above-mentioned opposing direction refers to the direction in which the surface of the wire distribution board and the surface of the continuity inspection board approach or separate from each other. That is, the direction in which the distance between the surface of the opposing electric wire wiring board and the surface of the continuity inspection board is changed is referred to.

  Further, the movement refers to relative movement of the electric wire wiring board and the continuity inspection board, and more specifically, movement of one or both of the electric wire distribution board and the conduction inspection board. In addition, the said movement also includes the case where one part moves besides the case where the whole surface of the said electric wire wiring board and the conduction | electrical_connection inspection board moves.

  According to the present invention, the connector and the continuity inspection apparatus can be easily connected by adjusting the distance between the boards in the direction in which the wire wiring board and the continuity inspection board face each other.

  In addition, even when the covered wire is three-dimensionally wired, the covered wire can be subjected to a conduction inspection at a position where the conduction inspection can be performed without interfering with the conduction inspection device provided on the conduction inspection board. The wire wiring board and the continuity inspection board can be moved relative to each other.

  More specifically, since the coated electric wire is three-dimensionally wired according to the arrangement of the electronic devices and the like provided at a predetermined position in the vehicle, for example, the electric wire wiring which is opposed in the vertical direction In the continuity inspection system for conducting continuity inspection of the coated electric wire using the board and the continuity inspection board, when one of the wire wiring board or the continuity inspection board is horizontally moved to the lower part of the other, three-dimensional wiring The coated wire may interfere with the continuity inspection apparatus provided on the continuity inspection board during movement.

  However, according to the present invention, when moving at least one of the electric wire wiring board and the conduction inspection board, the electric conduction inspection board is provided with the coated electric wire and the like three-dimensionally wired to the electric wiring wiring board. After parallel movement while maintaining the distance between the boards so as not to interfere with the continuity inspection apparatus, the wire wiring board and the continuity inspection board can be relatively moved in the opposing direction.

  Therefore, the wire arrangement can be performed at a position where the conduction inspection of the coated electric wire can be performed without the coated electric wire, which is three-dimensionally wired in the electric wire wiring board, interfering with the conduction inspection device provided in the conduction inspection board. The board and the continuity inspection board can be moved relative to each other, and the continuity inspection of the coated wire can be performed.

  According to this aspect of the invention, the connector gripping portion capable of reliably gripping the connector can be disposed even in a narrow place where the continuity inspection device can not be disposed.

  More specifically, as the number of power supplies and electronic devices provided in a vehicle increases, the covered wire increases, and the connector joined to the end of the covered wire is concentrated in a place where a power supply or the like is arranged, for example. Therefore, there is no room for arranging the continuity inspection device. However, the size of the separately provided connector gripping portion is smaller than in the case where the connector gripping portion and the connector connecting portion are integrated, even in a narrow place where the connectors are concentrated. The connector gripping portion can be disposed. Therefore, the connector can be arranged at a desired position.

  In addition, since the connector connection portion is not disposed on the wire wiring board, the connector connection portion is disposed at a place where the ends of the coated wires are densely arranged or at a position where it interferes with the laying of the coated wires. It is not necessary to do so, and the coated wire can be wired in a desired shape.

  Further, as an aspect of the present invention, at least one of the continuity inspection board and the electric wire wiring board can be provided with an inspection board position adjusting mechanism for adjusting a relative position between the electric wire wiring board and the conduction inspection board.

  According to the present invention, the position of the continuity inspection board can be adjusted with respect to the position of the wire wiring board so that the connector and the connector connection portion are connected. In other words, the connector gripped by the connector grip portion can be reliably connected to the connector connection portion.

As a mode of this invention, the continuity inspection board can be constituted combining a plurality of division inspection boards.
When the continuity inspection board is constituted by the divided inspection boards, for example, in the case where the continuity inspection board is constituted by the divided inspection boards divided into a single continuity inspection board, the divided inspection boards are arranged. This also includes the case where the continuity inspection board is configured, and the case where the continuity inspection board is configured by combining other divided inspection boards independent of the divided inspection boards obtained by dividing one continuity inspection board. Moreover, the said division | segmentation test | inspection board includes the case where it forms in the shape different from another division | segmentation test | inspection board besides the case where it forms in the same magnitude | size, or when formed in a different magnitude | size.

  The confirmation of the above-mentioned conduction corresponds to each of the divided inspection boards when confirming the conduction of the coated electric wires arranged on the electric wire wiring board as a plurality of divided inspection boards as one sheet of the inspection board. In the case where the conduction of the coated wire is confirmed, the case in which the conduction of the corresponding coated wire is confirmed by a part of the plurality of divided inspection boards among the plurality of divided inspection boards may be included. That is, the divisional inspection board includes a configuration capable of conducting a conduction inspection as the continuity inspection board constituted by a plurality of the divisional inspection boards and a construction capable of performing a conduction inspection for each of the divisional inspection boards.

According to the present invention, it is possible to reduce an error in the connection position of the connector and the connector connection portion when conducting a continuity test of the coated electric wire.
More specifically, the sizes of the electric wire wiring board and the continuity inspection board may differ depending on the part or vehicle type of the vehicle on which the coated electric wire is arranged, and may have a considerable size depending on the part or vehicle type. When the alignment between the wiring board and the continuity inspection board having such a size is performed, for example, at the central portion of the continuity inspection board configured as an integral unit, the vicinity of the position where the alignment is performed In this case, the connector gripped by the connector gripping portion can be reliably connected to the corresponding connector connection portion, but on the end side of the continuity inspection board, the positions of the connector and the connector connection portion Error may increase and it may not be possible to connect.

However, according to the present invention, in order to align the connector and the connector connection portion wired on the wire wiring board for each of the divided inspection boards obtained by dividing the conduction inspection board, the entire conduction inspection board An error with the wiring board can be reduced.
Therefore, the connector and the connector connection portion can be reliably connected to each other regardless of the location of the coated wire arranged on the wire distribution board.

  Further, as an aspect of the present invention, at least one of the connector gripping portion, the connector connecting portion, and the connector is arranged such that the connector gripped by the connector gripping portion is at a position where it is connected to the connector connecting portion. And a connection position adjustment mechanism that adjusts the position of the

  The adjustment of the above-mentioned position means, for example, all the connection between the connector and the connector connection portion in the case of adjusting the position in the horizontal direction with respect to the wire wiring board or in the case of adjusting the position in the vertical direction. Including the case where it is possible to adjust the orientation.

  In addition, at least one of the above cases is the case where the position of only one of the connector gripping portion, the connector connecting portion, or the connector is adjusted, or, for example, the position of the connector gripping portion is adjusted in the horizontal direction Positioning by a plurality of parts, for example, when the position of the connector connection portion is adjusted in the vertical direction, or when both the connector grip portion and the connector connection portion can be positionally adjusted in all directions. Including the case of adjusting the entire position in combination.

According to the present invention, the connector can be reliably connected to the connector connection portion.
More specifically, as the number of the covered electric wires increases as the number of electronic devices increases as described above, and the number of the connectors to be gripped by the connector gripping portion also increases, for example, the connector to the connector gripping portion When holding the connector, an error may occur in position because the connector is not securely held by the connector holding portion due to an artificial error.

However, even if there is an error between the position of the connector and the connection position with the continuity inspection device as described above, the connection position adjustment mechanism can connect the position of the connector with the continuity inspection device. It can be adjusted to the position.
Therefore, the connector can be reliably connected to the continuity inspection device, and the continuity inspection of the coated wire including the connector at the end can be reliably performed.

  Further, as an aspect of the present invention, at least one of the connector gripping portion, the connector connecting portion, and the connector is directed toward a connection position where the connector gripped by the connector gripping portion is connected to the connector connecting portion. And a moving mechanism for connection.

The above-mentioned movement refers to moving the connector grip portion, the connector connection portion or the connector relatively, and in the case of moving in the horizontal direction, in the case of moving in the vertical direction, the horizontal direction and the vertical direction are aligned. Also when moving.
In addition, in the case of moving the connector gripping portion, the connector connecting portion, the connector, and the like independently, for example, moving the connector gripping portion in the horizontal direction and moving the connector connecting portion in the vertical direction. And, including moving these in conjunction.

According to the present invention, it is possible to reliably connect the connector held by the connector gripping portion and the connector connecting portion.
More specifically, the connector and the connector connection portion may not be disposed at a connectable position with a predetermined distance due to, for example, an error at the design stage or an error at the time of laying of the coated wire. . In such a case, it is not clear from the result of the continuity test whether there is no continuity in the coated electric wire or contact failure between the connector and the connector connection portion, and it is necessary to confirm both, and it takes time and effort for confirmation. It will be necessary.

  However, according to the present invention, even when the connector and the connector connection portion have a predetermined interval, the connector connection portion or the like is moved to a position where the connector can be connected to the connector connection portion. The connector and the connector connection can be connected reliably. Therefore, the continuity test of the coated wire can be performed accurately.

Further, as an aspect of the present invention, the wire wiring board and the continuity inspection board can be formed to have the same size.
According to the present invention, the possibility of an error occurring in the positional relationship between the connector gripping portion and the continuity inspection device can be reduced.

More specifically, since the wire wiring board and the continuity inspection board have the same size, it is easy to determine the position of the connector gripping portion to be held with respect to the connector and the connector, and the connector and the continuity inspection board Since it is easy to match the position of the continuity inspection device with which it is equipped, it is possible to reduce the possibility of an error occurring in the positional relationship between the connector gripping portion and the connector connecting portion.
Therefore, the connection inspection board can be used for accurate connection, and the conduction inspection of the wires disposed in the wire wiring board can be performed more reliably.

Moreover, as an aspect of this invention, the said electric wire wiring board and the said continuity test board can be comprised with the same material.
According to the present invention, for example, even when there is a change in the environment such as temperature and humidity, it is possible to make the amounts of change in the shapes of the wire wiring board and the continuity inspection board substantially the same. Thereby, the difference | error of the position of the said electric wire wiring board and the said continuity test board can be reduced. Therefore, even if the environment changes, the continuity inspection of the wires disposed in the wire wiring board can be performed more reliably.

In the following, a method of continuity inspection of the harness 4 with a terminal using the continuity inspection system 1 having such a configuration will be described based on FIGS. 5 to 9.
First, the wiring step (step s1) of the harness 4 with a terminal, the horizontal movement step (step s2) of the wire wiring board 2 and the movable table 3, the vertical movement step (step s3) of the wire wiring board 2, connector 43 A conduction inspection method of the terminal harness 4 including the connection step (step s4) of the connection body 633 and the conduction inspection step (step s5) will be briefly described based on FIG.

  First, the terminal harness 4 is wired on the wiring board 21 based on a predetermined design (step s1), and the wiring board 21 on which the terminal harness 4 is wired is installed on the movable stand 3 The wire wiring board 2 is held by the movable table 3 and moved horizontally in the -X-axis direction to be stored in the storage space S of the leg 32 (step s2). Next, the wire wiring board 2 is moved upward using the lift mechanism 55 so that the connector 43 provided on the wire wiring board 2 and the connection body 633 provided on the continuity inspection board 5 can be connected. (Step s3). Then, the connector 633 is moved in the direction of the connector 43, the connector 43 and the connector 633 are connected (step s4), and a continuity test of the terminal harness 4 is performed (step s5).

After the continuity inspection, the electric wire wiring board 2 on which the terminal harness 4 is wired can be separated from the movable stand 3 by performing the reverse process.
Specifically, after the connector 43 and the connector 633 are separated by returning the piston 635 upward, the electric wire wiring board 2 can be held on the movable stand 3 by lowering the lifting mechanism 55 downward. . Then, by moving the movable base 3 holding the wire wiring board 2 horizontally in the + X axis direction and taking it out of the storage space S, the wire wiring board 2 can be moved without causing interference with the continuity inspection board 5. It can be separated from three.

Each step will be described in detail below.
In the wiring process of the terminal harness 4 (step s1), the wiring path of the terminal harness 4 is designed in advance, and the wiring jig 22 is arranged on the upper surface of the wiring board 21 based on the design. While being provided, the connector gripping portion 62 is disposed at a position where the end of the terminal harness 4 is disposed. At this time, the wiring jig 22 and the connector gripping portion 62 are fixed to the wiring board 21 using the fixing tool provided on the bottom surface of the wiring jig 22 and the fixing tool provided on the holding portion 623.
Next, the crimped terminal 42 is joined to the end of the coated electric wire 41 of a desired length, and the crimped terminal 42 is attached to the housing portion 43a to integrally form the coated electric wire 41, the crimped terminal 42 and the connector 43. Prepare the harness 4 with terminals. Then, the terminal-equipped harness 4 is wired along the wiring jig 22 disposed on the wiring board 21, and the connector 43 is fitted into the gripping recess 624 from above. By fitting the connector 43 into the holding recess 624 from the upper side, the covered electric wire 41 can be extended from the cutout 625 in the wiring direction, so the connector holding unit 62 does not disturb the wiring of the terminal harness 4.

  Thus, by arranging the harness 4 with terminals sequentially on the wiring board 21 and fitting the connector 43 at the end to the connector grip portion 62, the wiring designed in advance on the upper surface of the wiring board 21 The terminal-equipped harness 4 can be wired in the same shape as the cable path, and the plurality of wired terminal-equipped harnesses 4 are protected by, for example, an exterior such as a tape or a protector and bundled together to form an integral unit.

  Next, the wire wiring board 2 on which the terminal harness 4 is wired is installed on the moving table 3 and the wire wiring board 2 is held by the wiring board holding means (not shown) provided on the outer frame 31 (See Figure 2). Then, the movable stand 3 holding the wire wiring board 2 to a position at which the movable stand 3 is temporarily fixed at a desired position by positioning means (not shown) provided on the continuity inspection stand 52 is a storage space of the continuity check board 5 The horizontal movement is made to S (see FIG. 6), and the movement of the movable base 3 is restricted by the stopper provided on the caster 33. Thus, the wire wiring board 2 and the movable stand 3 can be stored in the storage space S (step s2).

Next, the vertical movement step (step s3) of the electric wire wiring board 2 will be described based on FIG.
The movement of the movable stand 3 is restricted at a desired position, so the wiring board 21 arranged on the movable stand 3 and the continuity inspection board 5 are arranged at corresponding positions. Therefore, the through holes 24 penetrating the wiring board 21 and the elevating mechanism 55 are disposed at corresponding positions, and the relative position adjusting recess 23 provided on the upper surface of the wiring board 21 and the inspection board 51 The relative position adjustment projection 56 provided on the lower surface is disposed at the corresponding position. Therefore, the protrusion 55 a can be fitted in the through hole 24 by raising the lifting mechanism 55 upward (in the + Z axis direction) by a lifting device (not shown).

  Under the present circumstances, even if the position of the through-hole 24 provided in the board 21 for wiring arranges with the position of the corresponding projection part 55a, the upper end of the projection part 55a becomes hemispherical one size smaller than the diameter of the through-hole 24 Therefore, the projection 55a plays a role of a taper, and the projection 55a is reliably fitted in the through hole 24.

  Next, by raising the lifting mechanism 55 in a state in which the projecting portion 55a and the through hole 24 are fitted, the wire wiring board 2 is lifted (see FIG. 7C), and the wiring board 21 and the inspection board As a result, the relative position adjustment recess 23 and the relative position adjustment projection 56 are fitted.

  Specifically, since the wire wiring board 2 and the continuity inspection board 5 are integrally configured via the elevating mechanism 55 by the through hole 24 and the support 54 a being fitted, it is for wiring The relative position adjustment recess 23 and the relative position adjustment protrusion 56 respectively provided on the plate 21 and the inspection plate 51 are disposed at positions facing each other. By further raising the lifting mechanism 55 in this state, the relative position adjustment recess 23 and the relative position adjustment protrusion 56 can be fitted.

  Further, even if there is a deviation between the positions of the wiring board 21 and the inspection board 51, the lower surface of the relative position adjustment projection 56 has a recess 23a provided in the relative position adjustment recess 23 The protrusion 56a has a diameter slightly smaller than the diameter, and the recess 23a is formed in a tapered shape, so that the protrusion 56a is engaged with the recess 23a when the wiring board 21 is lifted. It is possible to adjust the position.

  More specifically, since the surface of the horizontal plate 53 on which the inspection plate 51 is disposed is smooth, the horizontal plate 53 can be moved in the horizontal direction. Therefore, even when the positions of the corresponding recesses 23 a and the protrusions 56 a are shifted, when the protrusions 56 a are fitted to the recesses 23 a formed in a tapered shape, on the horizontal plate 53. The position of the inspection plate 51 can be easily adjusted so that the inspection plate 51 disposed can move horizontally on the horizontal plate 53 and the projection 56a can be fitted to the recess 23a. Therefore, the position of the continuity inspection board 5 can be adjusted so that it can be appropriately positioned relative to the wiring board 2.

According to the above-described process, the positions of the electric wire wiring board 2 and the continuity inspection board 5 can be adjusted so that the connector 43 can be connected to the connector 633.
In addition, since the wire wiring board 2 and the continuity inspection board 5 are the same material and have the same size, the error of the position due to temperature, humidity, etc. is reduced, so the continuity with the wiring board 2 is conducted. Position adjustment with the inspection board 5 can be performed more reliably.

  In addition, even if the wiring board 21 or the inspection board 51 is not completely parallel, the relative position adjustment recess 23 and the relative position adjustment protrusion 56 are fitted by raising the lifting mechanism 55. In this case, a load (not shown) provided in the relative position adjustment protrusion 56 can absorb the load applied to the relative position adjustment protrusion 56, so a large number of the load arrangement can be provided on the wire wiring board 2 and the continuity inspection board 5 Excessive load is not applied to a part of the relative position adjustment recess 23 and the relative position adjustment protrusion 56 which are being carried out.

Next, the step of connecting the connector 43 and the connector 633 (step s4) will be described with reference to FIGS.
The wiring board 21 and the inspection board 51 which have passed through the above-described vertical movement step (step s3) are, as shown in FIG. 8, a connection contained in the connector 43 gripped by the connector gripping portion 62 and the connector connecting portion 63. The body 633 is disposed at the opposite position. The connector 43 is firmly held by the connector holding portion 62 by being pressed by the connector adjusting portion 65.

The connection step (step s4) between the connector 43 and the connector 633 arranged as described above will be described in detail.
First, when the piston 635 provided inside the connector connection portion 63 is lowered in the −Z axis direction, the connector 433 is pushed out in the + Y axis direction (see FIG. 9A). At this time, the connector grip portion 626 provided in the connector grip portion 62 is fitted with the connection portion side guide hole 637.

  When the connector adjustment portion 65 is further lowered, the connection guide recess 634 formed in the pushed connection body 633 fits with the connector 43 (see FIG. 9B), and the connection provided in the connection guide recess 634 The portion 632 and the crimp terminal 42 attached to the connector 43 are connected.

  Since the side (+ Y axis side in FIG. 8) on which the coated wire 41 of the connector 43 extends is in contact with the side of the notch 625, the connector 633 moves toward the connector 43 as well. 43 does not move in the + Y axis direction and fits in the connection guide recess 634, so that the box portion 42b of the crimp terminal 42 mounted on the connector 43 and the connection portion 632 can be connected.

Since the connection portion 632 and the crimp terminal 42 thus connected are connected to the continuity inspection main body 61 through the lead wire 64, the continuity inspection is performed to determine whether the terminal harness 4 is electrically connected. (Step s5).
In the present embodiment, the inspection plate 51 is formed of a single plate like the wiring plate 21. However, the inspection plate 51 is not limited to the present embodiment, and as shown in FIG. It is good also as continuity inspection system 1a constituted by division inspection board 51a which divided 51 into two sheets.

  Hereinafter, the continuity inspection system 1a will be described in detail based on FIG. Among the configurations of the continuity inspection system 1a described below, the same components as those of the continuity inspection system 1 in the above-described embodiment are denoted by the same reference numerals, and the description thereof will be omitted.

The divided inspection plate 51a has the same configuration as the inspection plate 51 except that the inspection plate 51 is divided in half with respect to the X-axis direction.
In addition, although the number of sheets of the division | segmentation test | inspection board 51a is made into two sheets in a present Example, it is not limited to this number of sheets, According to the magnitude | size of the wire wiring board 2, etc., it can change suitably. Further, the shape of the divided inspection board 51a is not limited to the shape of the present embodiment, and can be appropriately changed according to, for example, the shape of the electric wire wiring board 2 or the shape of the wired terminal-equipped wire harness 4 is there.

Specifically, like the inspection plate 51, when the wiring board 21 is disposed at a position facing the divided inspection plate 51a on the lower surface of the divided inspection plate 51a, the connector gripping portion 62 and the relative position The connector connection portion 63 and the connector adjustment portion 65 are disposed at positions corresponding to the position adjustment recess 23.
Further, as in the case of the inspection plate 51, the two divided inspection plates 51a are provided on the upper portion of the continuity inspection stand 52 configured of the inspection vertical members 52x, the inspection horizontal members 52y, and the inspection vertical members 52z. It is disposed on the horizontal plate 53.

  The continuity inspection main body 61 which is a configuration of the continuity inspection device 6 is disposed on the divided inspection plate 51a positioned on the −X axis side, and the lead wires 64 are wired on the divided inspection plate 51a positioned on the + X axis side Lead wire 64a connected to the connection body 633, and a lead wire 64b arranged on the divided inspection plate 51a located on the -X-axis side, which is a connection connector for the lead wire 64 It is connected via the connection connector 66. The end of the lead wire 64 b is connected to the continuity test main body 61.

The continuity inspection method of continuity inspection system 1a which has such composition is explained.
Similar to the continuity inspection system 1, the continuity inspection system 1 a holds the wiring board 21 on which the terminal harness 4 is wired by holding the moving table 3, and the desired position of the storage space S formed by the continuity inspection board 5 It can move up to. After moving the movable table 3 to a desired position, the lifting plate 55 is brought close to the divided inspection plate 51 a by raising the lifting mechanism 55.

Here, as in the case of the continuity inspection system 1, by raising the elevating mechanism 55, the positions of the divided inspection plate 51 a and the wiring board 21 can be adjusted.
Specifically, as shown in FIG. 7, the lifting mechanism 55 lifts the wiring board 21 so that relative position adjusting projections 56 provided on the lower surface of each divided inspection board 51a, and the wiring board The relative position adjustment recess 23 provided on the upper surface of the housing 21 is fitted. Under the present circumstances, since the recessed part 23a provided in the relative position adjustment recessed part 23 is a taper shape, simultaneously with the protrusion 56a entering the recessed part 23a, the wiring board 21 corresponding to the position of the division inspection board 51a If there is an error between the position and the relative position adjustment protrusion 56 and the relative position adjustment recess 23, the divided inspection plate 51a moves horizontally on the horizontal plate 53 in the process of fitting the relative position adjustment protrusion 56 to the wiring plate 21. It corresponds to the position. Therefore, the connector 43 gripped by the connector grip portion 62 and the connector 633 can be set at positions suitable for connection.

  Here, in continuity inspection system 1a, since each divided inspection plate 51a can adjust the position independently, connection body 633 provided on each divided inspection plate 51a and corresponding connector 43, and Can be placed at an appropriate position. That is, compared with the case where the inspection plate 51 is a single plate, the positional error between each connector 43 and the connection body 633 is small, and the connector 43 and the connection body 633 can be connected reliably.

Thus, at least one of the wire wiring board 2 for wiring the terminal harness 4 whose end is joined to the connector 43 and at least one of the continuity inspection devices 6 for testing the continuity of the terminal harness 4 while connecting to the connector 43 The continuity inspection system 1 provided with the continuity inspection board 5 having a part can efficiently conduct the continuity inspection of the harness 4 with a terminal wired in the wire wiring board 2.
If it explains in full detail, by directly connecting the connector 43 joined to the end of the harness 4 with a terminal wired to the wire wiring board 2 and the continuity inspection device 6 provided to the continuity inspection board 5 The continuity inspection of the terminal harness 4 can be performed in a state of being wired to the wire wiring board 2 without removing the terminal harness 4 wired to the board 2 from the wire wiring board 2.

  Therefore, at the time of the continuity inspection, it is possible to omit the labor of attaching the terminal harness 4 disposed on the wiring layout board 2 from the wiring layout board 2 and attaching it to the continuity inspection board 5, and the efficiency of the continuity inspection. It can be improved. Moreover, since it is not necessary to transfer the harness 4 with a terminal, damage to the harness 4 with a terminal which might occur at the time of transfer of the harness 4 with a terminal can be prevented.

  Also, by providing the caster 33 that enables the movable base 3 holding the wire wiring board 2 to be moved so that the wire wiring board 2 and the continuity inspection board 5 face each other, the harness 4 with terminals can be arranged It is possible to easily and efficiently carry out the work of laying on the siding board 2.

  Specifically, for example, after wiring the harness 4 with a terminal to the wire wiring board 2 located at a position away from the conduction inspection board 5, the connector 43 and the conduction inspection apparatus are moved by moving the wiring board 2. 6 can be approached. That is, the wiring work of the terminal harness 4 is carried out in a place where the continuity inspection board 5 does not get in the way, and the wiring board 2 is moved after the wiring is completed. The harness 4 and the continuity inspection device 6 provided on the continuity inspection board 5 can be connected in close proximity. Therefore, the wiring operation of the harness 4 can be performed easily and efficiently.

  In the present embodiment, the movable base 3 for holding the wire wiring board 2 is moved, that is, the wire wiring board 2 is moved, but the present invention is not limited to this. It is good also as a structure which moves the conduction inspection board 5 which comprises 5 and it is good also as a structure which can move both the electric wire wiring board 2 and the conduction inspection board 5.

  Further, by providing the lifting and lowering mechanism 55 that moves the wire wiring board 2 in the direction in which the wire wiring board 2 and the continuity inspection board 5 face each other, the direction in which the wire wiring board 2 and the continuity inspection board 5 face each other The connector 43 and the continuity inspection apparatus 6 can be easily connected by adjusting the distance between the boards.

Furthermore, the wiring harness 2 is disposed at a position where the continuity inspection of the terminal harness 4 can be performed without interference with the continuity inspection device 6 provided on the continuity inspection board 5 in general, with the terminal harness 4 arranged three-dimensionally. And the continuity inspection board 5 can be moved relative to each other.
Specifically, since the harness 4 with a terminal is three-dimensionally wired according to the arrangement of the electronic devices and the like provided at a predetermined position in the vehicle, the wiring board 2 and the continuity inspection board 5 If the wire wiring board 2 is horizontally moved under the continuity inspection board 5 so that the connector 43 and the connection body 633 approach when conducting the continuity inspection of the harness 4 with a terminal, three-dimensional during movement There is a possibility that the wired harness 4 with a terminal may interfere with the continuity inspection device 6 provided on the continuity inspection board 5, but by providing an elevating mechanism 55 capable of moving the wire wiring board 2 upward, the terminal After parallel movement while maintaining the distance between the boards so that the attached harness 4 and the continuity inspection device 6 do not interfere with each other, the wire wiring board 2 and the continuity inspection board 5 can be relatively moved in the opposing direction.

  Therefore, the wire harness is arranged at a position where the continuity inspection of the terminal harness 4 can be performed without interference with the continuity inspection device 6 provided on the continuity inspection panel 5 with the terminal harness 4 wired three-dimensionally in the wire installation board 2 The siding board 2 and the continuity inspection board 5 can be moved relative to each other, and the continuity inspection of the terminal harness 4 can be performed.

  Further, the connector grip portion 62 for gripping the connector 43 which is a component of the continuity inspection device 6 and the connector connection portion 63 for connection with the connector 43 are separately configured, and the connector grip portion 62 By providing the connector connection portion 63 on the continuity inspection board 5, it is possible to reliably ensure that the continuity inspection main body 61 and the connector grip portion 62 which are integrally formed can not be disposed even in a narrow place. A connector gripping portion 62 capable of gripping the connector 43 can be disposed.

  More specifically, as the number of power supplies and electronic devices provided in the vehicle increases, the terminal harness 4 increases and the connector 43 joined to the end of the terminal harness 4 is placed, for example, in a place where the power supply is disposed. Because of the high density, there is no room for arranging the connectors 43. However, since the size of the separately provided connector gripping portion 62 is smaller than when the connector gripping portion 62 and the connector connecting portion 63 are integrated, even in a narrow place where the connectors 43 are densely packed. The connector gripping portion 62 can be disposed. Therefore, the connector 43 can be arranged at a desired position.

  In addition, since the connector connection portion 63 is not disposed on the wire wiring board 2, the connector connection portion 63 is located at a position where the end portions of the terminal harness 4 are densely packed and the wiring of the terminal harness 4 is interrupted. It is not necessary to arrange, and the terminal harness 4 can be wired as desired.

  Further, the electric wire wiring board 2 and the continuity inspection board 5 are provided with a relative position adjustment recess 23 for adjusting the relative position between the electric wire wiring board 2 and the continuity inspection board 5, a relative position adjustment projection 56 and a horizontal plate 53. Thus, the position of the continuity inspection board 5 can be adjusted with respect to the position of the wire wiring board 2 so that the connector 43 and the connector 633 are connected. In other words, the connector 43 held by the connector gripping portion 62 and the connector 633 can be reliably connected.

  In addition, the connector adjustment unit 65 for adjusting the position of the connector 43 so that the connector 43 held by the connector holding unit 62 is connected to the connection unit 633 securely connects the connector 43 to the connection unit 633. can do.

  More specifically, as the number of the harnesses with terminals 4 increases as the number of electronic devices increases as described above, and the number of connectors 43 gripped by the connector gripping portion 62 also increases, for example, the connector 43 is used as the connector gripping portion 62 When gripping, the connector 43 may not be reliably gripped by the connector gripping portion 62 due to a human error, which may cause a positional deviation.

  However, even if the position of connector 43 deviates from the connection position with connection body 633 as described above, connector adjustment portion 65 can adjust the position of connector 43 to a position where connection with connection body 633 is possible. The continuity inspection of the terminal harness 4 having the connector 43 at the end thereof securely with the connector 43 can be reliably performed.

  Further, by providing the piston 635 for moving the connection body 633 toward the connection position where the connection body 633 is connected to the connector 43 held by the connector holding portion 62, the connector 43 held by the connector holding portion 62 and the connection body 633 can be connected securely.

Further, by forming the wire wiring board 2 and the continuity inspection board 5 to have the same size, the possibility of an error occurring in the positional relationship between the connector gripping portion 62 and the continuity inspection apparatus can be reduced.
More specifically, since the sizes of the wire wiring board 2 and the continuity inspection board 5 are equal, it becomes easy to determine the position of the connector gripping portion 62 to be held relative to the connector 43 and the connector 43. It is easy to match the position of the continuity inspection device with which the connection inspection device is provided, thereby reducing the possibility of an error in the positional relationship between the connector gripping portion 62 and the connector 633.

  Therefore, the connection can be made with high accuracy using the continuity inspection board 5, and the continuity inspection of the coated electric wire disposed in the electric wire wiring board 2 can be performed more reliably.

  Further, by configuring the wire wiring board 2 and the continuity inspection board 5 with the same material, for example, even when there is a change in the environment such as temperature and humidity, the wire wiring board 2 and the continuity inspection board 5 The amount of change such as the shape of can be made substantially the same. Thereby, the difference | error of the position of the wiring board 2 and the continuity test board 5 can be reduced. Therefore, even if the environment changes, the continuity inspection of the coated wire disposed in the wire distribution board 2 can be performed more reliably.

  Further, by configuring the continuity inspection board 5 by combining a plurality of divided inspection boards, it is possible to reduce an error in the connection position between the connector 43 and the connection body 633 when conducting the continuity inspection of the harness 4 with a terminal. it can.

  More specifically, the sizes of the wiring board 2 and the continuity inspection board 5 differ depending on the part of the vehicle and the vehicle type in which the terminal harness 4 is wired, and may have a considerable size depending on the place and the vehicle type. When the alignment between the wiring board 2 having such a size and the continuity inspection board 5 is performed, for example, at the central portion of the continuity inspection board 5 configured as one unit, the vicinity of the location where the alignment is performed In this case, the connector 43 gripped by the connector gripping portion 62 and the corresponding connector 633 can be reliably connected, but on the end side of the continuity inspection board 5, the error in the position between the connector 43 and the connector 633 May become too large to be connected.

However, according to the present invention, in order to align the connector 43 wired to the wire wiring board 2 with the connector 633 every divided inspection board obtained by dividing the conduction inspection board 5, the whole of the conduction inspection board 5 and the electric wire arrangement It is possible to reduce the error with the yard 2.
Therefore, the connector 43 and the connector 633 can be reliably connected to each other with the terminal harness 4 installed at any location on the wire wiring board 2.

  Further, among the configurations of the continuity inspection device 6, since configurations other than the connector gripping portion 62 can be disposed on the inspection plate 51, the continuity inspection can be performed using the common inspection plate 51, Conduction inspection of the terminal-equipped harness 4 arranged on a plurality of wiring boards 21 can be performed, and the cost can be largely reduced as compared with the case where the conduction inspection apparatus 6 is provided for each of the wiring boards 21. .

  Furthermore, since the connector gripping portion 62, the connector connecting portion 63, etc. can be replaced, the continuity inspection of the terminal harness 4 corresponding to various designs can be performed, and temporarily the connector gripping portion 62 or the connector connecting portion 63 Even in the case of damage, it is sufficient to replace the connector gripping portion 62 and the connector connecting portion 63 which are the individual configurations, and the cost can be reduced as compared with a case where the entire continuity inspection device 6 is replaced.
