[0001]
[Industrial application fields]
The present invention relates to a wire guide device used for guiding a wire when the wire is inserted into a wire insertion hole of a housing in a process of manufacturing a wire harness assembly.
[0002]
[Prior art]
As a general configuration of the wire harness assembly, as shown in FIG. 2A, a configuration in which a pair of contacts 12 and a pair of wires 14 connected to a workpiece 22 are connected in a housing 16. Things are known.
[0003]
In the wire harness assembly 10, a pair of contact insertion holes 18 for inserting the pair of contacts 12 is formed in the housing 16. In the wall portion 16a and the rear wall portion 16b, wire insertion holes 20a and 20b (see FIG. 2B for 20b) through which the wires 14 are inserted are formed so as to be substantially the same in axis. Then, as shown in FIG. 2 (b), the wires 14 are inserted from the front of the housing 16 through the wire insertion holes 20 a to the positions penetrating the wire insertion holes 20 b, and then the contacts 12 are inserted into the contact insertion holes 18. The wire harness assembly 10 is manufactured by inserting it into the wire 14 and press-contacting it to the wire 14.
[0004]
Conventionally, the wire insertion operation in the manufacturing process of the wire harness assembly 10 has been performed manually using a guide block 30 as shown in FIG.
[0005]
That is, as shown in the drawing, a pair of tapered guide grooves 32 having a concave cross section and a smaller cross section toward the rear are formed on the upper surface of the guide block 30 at the same pitch as the pair of wire insertion holes 20a. Is formed. The guide block 30 is brought into contact with the front surface of the housing 16 in a state where the guide grooves 32 and the wire insertion holes 20a are aligned. In this state, the operator grasps the pair of wires 14 with fingers. Then, by inserting these through the wire insertion hole 20a to a position penetrating the wire insertion hole 20b, the wire insertion work is performed. At that time, each guide groove 32 functions to guide the wire 14, so that the wire insertion work can be performed smoothly.
[0006]
When the wire insertion operation is completed, each contact 12 is inserted into each contact insertion hole 18 by the cylinder device 34 and pressed against each wire 14, whereby each contact 12 breaks the covering material of each wire 14. It is in contact with the center conductor and is connected to it.
[0007]
By the way, as shown in FIG. 2B, the wire harness assembly 10 has an inner diameter of the wire insertion hole 20a formed in the front wall portion 16a among the pair of front and rear wire insertion holes 20a and 20b. On the other hand, the inner diameter of the wire insertion hole 20b formed in the rear wall portion 16b is formed slightly larger. Thus, when the wire is inserted, even if the insertion direction of the wire 14 is slightly bent, the wire 14 can be inserted to the end without contacting the front surface of the rear wall portion 16b. It is designed to facilitate smoothing.
[0008]
[Problems to be solved by the invention]
However, when the workpiece 22 is a small one such as a small motor incorporated in a mobile phone, the wire harness assembly 10 connected to the workpiece 22 is also small, and the wire 14 is also very wire. The diameter is thin (for example, about 0.4 mm).
[0009]
Since such a thin wire is easily bent when an external force is applied, when the wire insertion operation is performed manually as in the prior art, it is not possible to perform the insertion operation without causing deformation of the wire tip. Not easy. That is, as shown in FIG. 18 (a), even if the insertion into the wire insertion hole 20a can be facilitated by the guide groove 32, the insertion into the wire insertion hole 20b occurs when the above deformation occurs. At this time, the wire 14 easily comes into contact with the front surface of the rear wall portion 16b. And when such contact | abutment generate | occur | produces, even if it inserts the contact 12 in the contact insertion hole 18 after that, there exists a problem that conduction | electrical_connection with the wire 14 cannot be achieved but it becomes a defective product.
[0010]
As shown in FIG. 18B, if the tip end of the wire 14 is cut obliquely, the contact is less likely to occur, but the above problem cannot be drastically solved.
[0011]
Further, in the wire harness assembly 10 provided with a pair of wires 14, even if the above-described conduction failure does not occur, due to the above insertion failure, as shown in FIG. There is a problem in that the length of the wire in which the insertion failure has occurred becomes longer than the other wire, resulting in bending. FIG. 19A shows an example when the workpiece 22 is a motor, and FIG. 19B shows an example when the workpiece 22 is another connector housing.
[0012]
The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a wire guide device capable of automatically performing a wire insertion operation without causing poor conduction or the like. .
[0013]
[Means for Solving the Problems]
The present invention is intended to achieve the above object by adopting a wire guide device having a structure that suppresses the deformation of the wire tip portion before or after the wire is inserted.
[0014]
That is, the present invention has a housing having a front wall portion and a rear wall portion arranged at a predetermined interval, and a wire insertion hole having substantially the same axis line formed in each wall portion, and both the wire insertion portions. In a step of manufacturing a wire harness assembly including a wire inserted through a hole and a contact inserted between the wall portions and pressed against the wire, the wire is inserted into the both wire insertion holes from the front. On the premise of the wire guide device used to guide the wire when inserting,
As described in claim 1, the first invention of the present application,
A front wire support member and a rear wire support member, which are arranged at a predetermined interval in front and rear with respect to each other in front of the front wall portion, each having a wire insertion passage substantially the same axis as the wire insertion holes;
A wire insertion mechanism for moving the wire together with the front wire support member to the rear in the axial direction of the wire insertion holes in a state where the wires are arranged in the wire insertion passages of the both wire support members;
Between the wire support members, the vicinity of the extension line of the axis of the wire insertion holes is arranged so as to extend in parallel with the extension line, and one end is fixed to one of the wire support members. A plurality of deformation suppression rods, and
The second invention of the present application, as described in claim 2,
A cylindrical guide member having an inner diameter larger than the outer diameter of the wire and an outer diameter smaller than the inner diameter of the wire insertion hole of the rear wall portion, and a cylindrical guide member formed at the front end;
A cylindrical guide member insertion mechanism for inserting the cylindrical guide member from the rear of the rear wall portion to the vicinity of the rear surface of the front wall portion through the wire insertion hole of the rear wall portion when the wire is inserted; It is characterized by.
[0015]
In the first invention of the present application, the “plurality of deformation suppression rods” is a period between the state where the wires are arranged in the wire insertion passages of both wire support members and the time when the wire insertion mechanism completes the rearward movement of the wires in the axial direction. As long as the deformation of the wire tip that can occur can be prevented from being increased by a predetermined amount or more due to the contact action with the wire, the number and arrangement of the deformation suppression rods, and the length of each deformation suppression rod, The cross-sectional shape and the like are not particularly limited.
[0016]
In the second invention of the present application, the “cylindrical guide member” is not limited to a specific configuration as long as the cylindrical portion is formed at the front end portion. As described above, the cylindrical portion may be formed only at the front end portion, or may be formed so as to penetrate to the rear end portion of the cylindrical guide member. The cross-sectional shape is not limited to a specific shape as long as the inner diameter is larger than the outer diameter of the wire and the outer diameter is smaller than the inner diameter of the wire insertion hole in the rear wall.
[0017]
[Effects of the invention]
In order to completely insert the wire into the pair of front and rear wire insertion holes of the housing, it is important to minimize the occurrence of deformation at the tip of the wire during the wire insertion operation.
[0018]
In this regard, in the first invention of the present application, a plurality of deformation suppression rods having one end fixed to either one of the two wire support members are provided between the front wire support member and the rear wire support member. Since the vicinity of the extension line of the axis of the wire insertion hole is arranged to extend in parallel with the extension line, if the wire is moved backward together with the front wire support member by the drive mechanism, the wire tip is deformed. The wire insertion work can be performed in a state of being maintained in a substantially straight state without being caused. Accordingly, not only can the housing front wall portion be easily inserted into the wire insertion hole, but also when the housing rear wall portion is inserted into the wire insertion hole, the wire is applied to the front surface of the rear wall portion. It can be easily inserted without touching. In this way, the wires can be completely inserted into both the wire insertion holes of the housing, so that the contact and the wire can be reliably connected by inserting and pressing the contact into the contact insertion hole.
[0019]
The second invention of the present application further includes a cylindrical guide member in which a cylindrical portion having an inner diameter larger than the outer diameter of the wire and an outer diameter smaller than the inner diameter of the wire insertion hole in the rear wall is formed at the front end portion. At the time of insertion, this cylindrical guide member is inserted from the rear of the rear wall of the housing through the wire insertion hole to the vicinity of the rear surface of the front wall of the housing by an insertion mechanism. Even when the wire insertion direction is bent due to deformation of the tip of the wire when inserted into the wire insertion hole of the rear wall, the wire is brought into contact with the inner surface of the cylindrical portion of the cylindrical guide member and the front surface of the wire rear wall It can be made not to contact. Therefore, it is possible to guide the tip end of the wire through the cylindrical portion and insert it easily into the wire insertion hole of the rear wall portion of the housing. In this way, the wires can be completely inserted into both the wire insertion holes of the housing, and thereafter, the contact and the wire can be reliably connected by inserting the contact into the contact insertion hole.
[0020]
Thus, according to the present invention, the wire insertion work can be automatically performed without causing a conduction failure or the like.

[0030]
Protrusions 54D and 56D are provided on the dividing surfaces of the main body parts 54A and 56A, and elongated holes 54E and 56E through which the protrusions 54D and 56D are inserted are formed in the holding parts 54B and 56B. By engaging the projections 54D and 56D with the long holes 54E and 56E, the main body portions 54A and 56A and the presser portions 54B and 56B are positioned in the closed state.
[0031]
Engagement levers 54F and 56F engaged with the presser portions 54B and 56B are rotatably supported by the main body portions 54A and 56A so as to hold the presser portions 54B and 56B in a closed state. Further, compression springs 54G and 56G are provided on the main body portions 54A and 56A so as to face the divided surfaces, and the presser portions 54B and 56B are always urged in the opening direction. Thus, when the engagement levers 54F and 56F engaged with the presser portions 54B and 56B are removed, the presser portions 54B and 56B are automatically opened by the elastic force of the compression springs 54G and 56G.
[0032]
The engaging levers 54F and 56F themselves are also always urged in the engaging direction by the compression springs 54H and 56H.

Further, on the rear side of the housing 16, a guide pipe 84 (cylindrical guide) is provided. Member).
[0041]
The insertion guide 80 has the same axis as that of the wire insertion passage 62, and the inner diameter of the rear half thereof is slightly larger than the inner diameter of the wire insertion hole 20a of the front wall portion 16a. A guide hole 86 extending in a taper shape is formed to penetrate in the front-rear direction. The insertion guide 80 is composed of two blocks 80A and 80B that are divided vertically with the axis of the guide hole 86 as a boundary. As shown in FIG. 9B, these blocks 80A and 80B are moved up and down by cylinders 88 and 90 attached to the machine base 74 directly or via brackets, and are closed in the illustrated state. Yes. The housing 16 is positioned on the housing guide 82 so that the wire insertion holes 20a and 20b formed in the front wall portion 16a and the rear wall portion 16b are the same as the axis of the wire insertion passage 62 of the rear wire support member 56. It has come to be supported.
[0042]
A cylindrical portion 84 a having a predetermined depth is formed at the front end portion of the guide pipe 84. The cylindrical portion 84a has an inner diameter larger than the outer diameter of the wire 14 (substantially equal to the inner diameter of the wire insertion hole 20a of the front wall portion 16a), and the outer diameter thereof is larger than the inner diameter of the wire insertion hole 20b of the rear wall portion 16b. A small dimensional value is set, and a tapered portion 84b that spreads forward is formed at the front end edge of the inner peripheral portion. Then, as shown in FIG. 9B, the guide pipe 84 reciprocates back and forth on the same axis as the wire insertion path 62 by a cylinder 92 attached to the machine base 74 via a bracket. ing.
[0043]
As shown in FIG. 9B, the guide pipe 84 is inserted from the rear of the rear wall portion 16b through the wire insertion hole 20b until it comes into contact with the rear surface of the front wall portion 16a by driving the cylinder 92. As shown in (c), by driving the cylinder 58 (having a larger power than the cylinder 94), the wire 14 is moved backward together with the front wire support member 54, and the tip of the wire 14 is moved. The portion is inserted through the guide hole 86 of the insertion guide 80 and the wire insertion hole 20a of the front wall portion 16a to the vicinity of the bottom of the cylindrical portion 84a of the guide pipe 84.

Next, in the contact insertion pressure contact operation, first, as shown in FIG. 10A, the contact 12 is supplied to the vicinity of the upper portion of the contact insertion hole 18 of the housing 16, and the guide pipe 84 is connected to the rear wall portion 16b. The wire insertion hole 20b is moved backward from the wire insertion hole 20b to a position away from the tip of the wire 14. Then, as shown in FIG. 10 (b), the contact 12 is held between the front and rear by the parallel chuck 98 of the clamp cylinder 96 disposed above it, and then the cylinder is attached to the machine base 74 via a bracket. The clamp cylinder 96 is lowered by 100, whereby the contact 12 is inserted into the contact insertion hole 18 and pressed against the wire 14. Thereafter, as shown in FIG. 10C, the contact gripping by the parallel chuck 98 is released, and the clamp cylinder 96 is retracted upward. Then, the two upper and lower blocks 80A and 80B of the insertion guide 80 are opened up and down.
[0045]
Next, in the tip cutting and continuity check stage D, first, as shown in FIG. 11A, an extra portion of the tip of the wire 14 protruding rearward from the housing 16 by the cutter unit 102 installed in the stage D. To cut. Thereby, the assembly of the wire harness assembly 10 is completed. The cutter unit 102 drives the cylinders 104 and 106 attached to the machine base 74 directly or via a bracket to move the pair of upper and lower cut blades 108 and 110 up and down along the rear surface of the housing 16. ing.
[0046]
Thereafter, as shown in FIG. 11B, a continuity check circuit 112 is connected to the contact 12 and the cutting blade 110 (in contact with the conducting wire at the tip end surface of the cut wire 14), and the indicator lamp is turned on. Then, it is checked that the contact 12 and the conductor of the wire 14 are conductive. This continuity check is performed for each of the pair of wires 14 by providing the cutting blade 110 independently for each wire 14 as shown in FIG. Thereby, it is possible to check which wire 14 has a conduction failure. Instead of such a continuity check method, as shown in FIG. 13B, it is also possible to employ a simple method for performing a continuity check by connecting a continuity check circuit 112 to a pair of contacts 12. is there.
[0047]
Next, in the discharge stage E, as shown in FIG. 12, the holding portions 54B and 56B of the wire support members 54 and 56 are lifted from the main body portions 54A and 56A, and the assembly and continuity check are completed. The appendage 10 can be taken out from the upper surface of the unit base 52. Thereby, the wire harness assembly 10 is discharged | emitted outside from the discharge chute 114 shown in FIG.
[0048]
Next, the effect of the present embodiment will be described.
[0049]
In order to completely insert the wire 14 into the wire insertion holes 20a and 20b of the pair of front and rear wall portions 16a and 16b formed in the housing 16, the tip end portion of the wire 14 is deformed during the wire insertion operation. It is important to minimize this.
[0050]
In this regard, in this embodiment, the six deformation suppression rods 64 whose rear end portions are fixed to the rear wire support member 56 are provided between the front wire support member 54 and the rear wire support member 56. Since the vicinity of the extension line of the axial line of the insertion holes 20a and 20b is arranged to extend in parallel with the extension line, if the wire 14 is moved backward together with the front wire support member 54 by the cylinder 58, the wire The wire insertion work can be performed in a state where the tip end portion of the 14 is maintained in a substantially straight state without being deformed.
[0051]
Therefore, the wire 14 can be easily inserted into the wire insertion hole 20a of the housing front wall portion 16a, and also when the wire is inserted into the wire insertion hole 20b of the housing rear wall portion 16b. Can be easily inserted without contacting the front surface of the rear wall portion 16b. Thus, the wire 14 can be completely inserted into both the wire insertion holes 20a, 20b of the housing 16, and thereafter, the contact 12 is inserted into the contact insertion hole 18 and pressed against the wire 14, whereby the contact 12 and the wire are inserted. 14 can be reliably established.
[0052]
In addition, in this embodiment, the compression springs 66 are inserted into the respective deformation suppression rods 64. The compression springs 66 are recessed portions 54Ac formed on the opposing surfaces of the wire support members 54 and 56, respectively. 54Bc and 56Ac, 56Bc can be displaced in the radial direction by the amount of play, so that the wire 14 can be elastically supported by these compression springs 66. And thereby, the said wire insertion can be smoothly performed also about the wire from which an outer diameter dimension differs a little.
[0053]
In the present embodiment, the guide pipe 84 is provided with a cylindrical portion 84a having an inner diameter larger than the outer diameter of the wire 14 and an outer diameter smaller than the inner diameter of the wire insertion hole 20b of the rear wall portion 16b. When the wire is inserted, the guide pipe 84 is inserted by the cylinder 92 from the rear of the housing rear wall portion 16b through the wire insertion hole 20b to the vicinity of the rear surface of the housing front wall portion 16a. When the wire 14 is inserted into the wire insertion hole 20b after the insertion hole 20a is inserted, the wire 14 is brought into contact with the inner surface of the tubular portion 84a of the guide pipe 84 even if the wire insertion direction is bent due to deformation of the tip of the wire 14, etc. Thus, the wire rear wall 16b can be prevented from coming into contact with the front surface. Therefore, thereafter, the tip end portion of the wire 14 can be guided by the tubular portion 84a and can be easily inserted into the wire insertion hole 20a of the housing rear wall portion 16b. Thus, the wire 14 can be completely inserted into the both wire insertion holes 20a and 20b of the housing. Thereafter, the contact 12 and the wire 14 are reliably connected by inserting the contact 12 into the contact insertion hole 18. Can be planned.
[0054]
Thus, according to the present embodiment, the wire insertion work can be automatically performed without causing poor conduction.
[0055]
Further, in this embodiment, in the work set stage A, the pair of wires 14 is rubbed in the wire insertion passage 62 by the rear wire support member 56, and both the wires 14 are extended linearly. Therefore, the lengths of both wires 14 of the assembled wire harness assembly 10 can be made uniform.
[0056]
In the above embodiment, the wire insertion passage 62 formed in the front wire support member 54 is formed by closing the concave groove 54Aa of the main body portion 54A and the concave groove 54Ba of the pressing portion 54B. However, as shown in FIG. 14, a deep U-shaped groove 54Aa ′ is formed in the main body portion 54A, and a rib 54Bb to be inserted into the deep groove 54Aa ′ is integrally formed in the holding portion 54B. The wire insertion passage 62 may be formed by forming the concave groove 54Ba ′ and closing them.

Thus, by setting it as the structure which has deep groove | channel 54Aa ', the wire 14 can be easily set in this U-shaped groove 54Aa'. At that time, if the chamfered portions 54Ac are formed on the shoulders on both sides of the upper end of the U-shaped groove 54Aa 'as shown in the drawing, the setting can be performed more easily. Further, as shown in the figure, if the rib 54Bb is formed to extend rearward, the concave groove 54Ba 'can also have a guide function for the wire 14.
[0058]
In addition, when this configuration is adopted for the rear wire support member 56, a configuration that is symmetric with respect to the configuration of the front wire support member 54 may be used.
[0059]
In the above embodiment, the base end portions of the six deformation suppressing rods 64 are all fixed to the rear wire support member 56. However, the rear wire support members 56 are arranged in a distributed manner on both wire support members 54 and 56. May be. For example, as shown in FIG. 15, the base end portions of the upper three deformation suppression rods 64 are fixed to the presser portion 54 </ b> B of the front wire support member 54 and the base ends of the lower three deformation suppression rods 64. The portion may be fixed to the main body portion 56 </ b> A of the rear wire support member 56.
[0060]
Further, in the above-described embodiment, the length of each deformation suppressing rod 64 is set to a length of about two thirds of the distance dimension when the distance between the wire support members 54 and 56 is maximized. However, instead of this, a dimension longer than the maximum distance dimension may be set, and the tip of the deformation suppressing rod 64 may be inserted into the rod insertion hole 54Ab formed in the front wire support member 54.

Moreover, in the said Example, although the apparatus which assembles the wire harness assembly | attachment body 10 provided with one pair of spaced apart wires 14 was demonstrated, it is the same structure also in the case of a single wire like a coaxial cable. Similar effects can be obtained. Furthermore, as shown in FIG. 16A, even in the case of a flat cable 14 ′ in which many wires 14 are arranged in parallel, by adopting the arrangement of the deformation suppression rod 64 as shown in FIG. The same operational effects as in the above embodiment can be obtained.
