Description

  The present invention relates to a wiring harness mounting structure for an optional connector, and more specifically, an optional connector connected to an electric wire terminal of a wiring harness routed in a vehicle such as an automobile is mounted on the outer peripheral surface of the wiring harness and is mounted as a disposable And the case where it is fitted to the mating connector on the optional component side.

  Wire harnesses that are routed to automobiles, etc. are pre-assembled with electric wires connecting connectors for optional components to the terminal, and these optional connectors are mounted on the outer peripheral surface of the wire harness and optional components are not mounted Is disposed in a disposable state and remains on the outer peripheral surface of the wire harness, and when an optional component is mounted, it is fitted and connected to a counterpart connector on the optional component side.

  Conventionally, as shown in FIG. 6A, an optional connector 100 is mounted on the outer peripheral surface of a wire harness 101, and an electric wire 102 connected to the connector 100 is wound around and attached to the wire harness 101 with an adhesive tape 103. In this case, since the adhesive tape 103 is not wound around the connector 100, there is an advantage that it is not necessary to remove the adhesive tape attached to the connector 100 when the connector 100 is separated from the wire harness 101 and fitted to the mating connector. However, when the connector 100 is made disposable and remains on the wire harness 101, there is a problem that the connector 100 is not stabilized and easily comes into contact with a peripheral member to cause abnormal noise.

In order to solve the problem of FIG. 6A, when the adhesive tape 103 is wound around the connector 100 and the wire harness 101 and the connector 100 is firmly fixed on the wire harness 101 as shown in FIG. There is also.
However, as described above, when the optional component is mounted, it is necessary to cut the adhesive tape 103 to release the adhesion between the connector 100 and the wire harness 101. At that time, since the adhesive tape 103 is fixed to the outer peripheral surface of the connector 100, a fine work for completely removing the cut end of the adhesive tape 103 is required. Moreover, even if the adhesive tape 103 is removed, there is a concern that the adhesive remains on the outer surface of the connector and becomes a resistance when it is fitted into the mating connector, resulting in poor fitting. Furthermore, the cut adhesive tape may remain on the outer peripheral surface on the wire harness 101 side, and the appearance of the completed vehicle may deteriorate, or may adhere to the surrounding high-temperature parts and movable parts, thereby impairing basic performance.

  In order to solve the above-described problem, the applicant of the present invention disclosed in Japanese Patent Laid-Open No. 2000-4525, as shown in FIGS. When the connector 100 is used, the electric wire 102 connected to the connector 100 is pulled in the direction of the arrow, and the connector 100 is pulled out from the wound portion of the adhesive tape 103 as shown in FIG. Is left on the main line side of the wire harness 101.

JP 2000-4525 A

  In the case of the connector fixing structure of Patent Document 1 shown in FIG. 7, the influence of the winding force (tension) of the adhesive tape 103 is strong, and the force for pulling out the connector 100 from the winding portion is not stable and is pulled with a strong force. Then, there is a possibility that the terminal of the terminal of the electric wire 102 is detached from the engaging portion of the connector 100 and only the electric wire 102 is pulled out, or the terminal is deformed, so that the connector pulling operation becomes difficult. In addition, as described above, the adhesive applied to one surface of the adhesive tape 103 remains on the outer surface of the connector 100, and may become a resistance and become a semi-fitted state when fitted and fitted into the mating connector. . Therefore, there is room for improving the connector fixing structure of Patent Document 1. On the other hand, if it is wound with a weak force, the connector 100 is not stably fixed to the wire harness with the adhesive tape 103. Therefore, when the connector 100 is in a disposable state and is held on the outer peripheral surface of the wire harness 101, the connector 100 may come out of the wound portion of the adhesive tape 103 due to running vibration or the like, which may cause abnormal noise.

  The present invention has been made in view of the above problem, and an optional connector mounted on the outer peripheral surface of the wire harness is stably held on the outer peripheral surface of the wire harness even if it is not fixed to the wire harness with an adhesive tape, and is in a disposable state. However, when it is fitted with a mating connector on the optional component side, the problem is to be easily taken out from the wire harness.

In order to solve the above problems, the present invention is equipped with an optional connector connected to an electric wire terminal drawn from a wire harness routed in a vehicle on the outer peripheral surface of the wire harness,
Using a cushion sheet provided on one side with a self-bonding layer that is fused when bonded to each other, folded back leaving a non-folded portion on one end side of the cushion sheet, providing a bag with the self-bonding layer facing up and down, The connector is accommodated in the bag and the upper and lower self-bonding layers around the connector are stacked and fixed, and the wire terminal connected to the connector is positioned on the non-folded portion,
When the connector is fitted to the mating connector, an optional connector wire harness mounting structure is provided in which the cushion sheet is removed.

  The cushion sheet provided with the self-bonding layer on one side is, for example, a self-bonding material that does not use an adhesive material laminated on one side of a cushioning base material made of a foamed urethane sheet, a butyl rubber sheet, or a nonwoven fabric sheet. Or a self-bonding layer integrally provided on one surface of a thick butyl rubber sheet. Examples of the self-bonding material include self-bonding materials made of butyl rubber, ethylene propylene rubber, silicone rubber, and the like.

  The self-bonding layers are firmly fixed when they are stacked on each other, but have a function of not sticking to others. Accordingly, the peripheral edge of the bag containing the connector and the self-bonding layers on the upper and lower surfaces of the bag around the connector can be fixed simply by being overlapped with each other. The connector can be protected from interference with surrounding members because the connector is covered with the cushion sheet until the connector is fitted with the mating connector or is disposable and continues to be mounted on the outer surface of the wire harness. Furthermore, even when it is disposable and mounted on the wire harness, sound generated by vibration or interference with peripheral members can be absorbed by the cushion sheet, and generation of abnormal noise can be reduced or prevented.

  On the other hand, the self-bonding layer on the inner surface of the bag is in contact with the outer surface of the connector housed in the bag. However, since the self-bonding layer does not use an adhesive, the adhesive does not adhere to the outer surface of the connector. Therefore, when removing the connector from the bag for mating connection with the mating connector on the optional component side, just cut the bag that is stuck by overlapping the self-bonding layer, or just pull the wire connected to the connector, The connector can be easily removed from the bag. In addition, since the adhesive does not remain on the outer surface of the connector that has been taken out, it is possible to increase the fitting accuracy without causing resistance when fitted into the mating connector. Furthermore, no adhesive remains on the outer surface of the wire connected to the connector and the wire harness on which the connector is mounted after the cushion sheet is removed.

A bag is formed by the folding in a state where the connector of the wire end is placed on the self-bonding layer side of the cushion sheet, and upper and lower self-bonding layers around the connector of the bag are overlapped and fixed.
If a bag for housing the connector is formed in advance on the cushion sheet and the connector is inserted into the bag, the workability is improved. However, since the upper and lower inner surfaces of the bag are self-bonding layers, the upper and lower inner surfaces are There is a risk that it will come into contact with the preparation and be fixed. Therefore, as described above, after placing the connector on the cushion sheet in the unfolded state, one end side is folded to form a bag, and the upper and lower inner surfaces of the bag are overlapped with each other. Since the work is simple, it does not cause a reduction in work efficiency.

  You may wind the outer periphery of the trunk wire of the wire harness which mounts the cushion sheet which accommodated the said connector, and this cushion sheet with an adhesive tape.

With this configuration, when the optional part is not mounted on the vehicle and the connector becomes a disposable connector and mounted on the wire harness, the connector is stably held together with the cushion sheet with an adhesive tape. Can do.
On the other hand, when an optional part is mounted and the connector is taken out from the cushion sheet bag so as to be mated with the mating connector, the adhesive tape is adhered and removed from the cushion sheet to be excised and does not remain in the connector.

  As described above, in the wire harness mounting structure for an optional connector according to the present invention, since the connector is accommodated in a bag provided in a cushion sheet having a self-bonding layer, a sheet covering the outer surface of the connector is provided. The adhesive does not remain and the adhesive does not remain, and the work of removing the cushion sheet and fitting the connector with the mating connector can be facilitated. In addition, even when optional parts are not mounted and optional connectors remain disposable and continue to be mounted on the wire harness, the upper and lower self-bonding layers on the periphery of the connector are stacked and fixed inside the cushion sheet bag. The connector can be kept immovable in the bag. In addition, the cushion sheet comes into contact with peripheral members, so that the connector can be protected and abnormal noise can be prevented. The protection function of this cushion sheet is the protection from the peripheral members that are generated during the period when the wire harness is transported to the automobile assembly line and assembled to the automobile on the assembly line, Works both as protection against interference. Furthermore, the cushion seat can reduce the vibration of the connector due to running vibration in the completed vehicle.

It is a perspective view of 2nd Embodiment. (A) (B) is a perspective view which shows a prior art example. (A) and (B) are drawings showing other conventional examples.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 4 show a first embodiment of the present invention.
A branch line 4 having an optional connector 5 connected to a terminal is branched out from a trunk line 3 in which a number of electric wires 2 are bundled in a wire harness 1 routed in an automobile, and the connector 5 is a self-bonding type. It is mounted on the outer peripheral surface of the trunk line 3 of the wire harness 1 using the cushion sheet 10.

  In the present embodiment, as shown in FIG. 2 (B), the cushion sheet 10 is formed by applying a self-bonding material made of an ethylene propylene rubber sheet on the surface of a base layer 11 made of a foamed urethane sheet as a base material. As shown in FIG.

  As shown in FIG. 3A, the cushion sheet 10 has a rectangular shape in the unfolded state, and the connector 5 at the end of the branch line 4 is placed on the upper surface of the cushion sheet 10 with the self-bonding layer 12 on the upper surface side. As shown in FIG. 3 (B), the connector 10 is folded in half with the two-dot chain line 10L as a refracted line, leaving the non-folded part 10a on one end side in the length direction on the mounting side of the branch line 4. A bag 15 for receiving the connector 5 is provided. As shown in FIG. 2C, self-bonding layers 12 a and 12 b arranged on the upper and lower inner surfaces of the bag 15 are overlapped and fixed around the periphery and the periphery of the connector 5.

As shown in FIG. 3B, the cushion sheet 10 is sized so that the length L and width W of the bag 15 to be formed are large enough to accommodate the connector 5 therein. In addition, it is cut out from the cushion sheet material.
Note that the size of the bag 15 provided in the cushion sheet 10 does not need to correspond exactly to the outer shape of the connector 5. For example, the cushion sheet having two types of large and small types or three types of large, medium, and small types of bags 15. 10 should be prepared. As shown in FIGS. 4A and 4B, in the state where the connector 5 is inserted into the bag 15, the upper and lower self-bonding layers 12a and 12b surrounding the connector 5 are overlapped and fixed. This is because the connector 5 can be held in the bag 15 so that it cannot be moved by simply adjusting the angle. Therefore, waste of the cushion sheet 10 can be eliminated.

  As described above, the connector 5 is housed and held in the bag 15 of the cushion sheet 10 and mounted on the outer peripheral surface of the main wire 3 of the wire harness 1 in a state where the assembly of the wire harness 1 is completed. The connector 5 in this state is held in the bag 15 of the cushion sheet 10 so as not to move. Therefore, the connector 5 can be protected from the peripheral members during the period from the transportation to the automobile assembly line to the assembly into the automobile.

  After the wiring harness is routed in the automobile, when the optional component is mounted on the automobile and the connector 5 is fitted to the mating connector on the optional component side, the bag 15 of the cushion sheet 10 is cut or connected to the connector 5 The connector 5 can be easily pulled out from the bag 15 by pulling the branch line 4 to tear the fixing portion on the insertion side of the bag 15.

  The self-bonding layer 12 of the cushion sheet 10 is not fused to the outer surface of the connector 5 drawn out from the bag 15. Therefore, there is no adhesive residue generated when the adhesive tape is wound, and the fitting with the counterpart connector is not hindered. In addition, the self-bonding layer 12 is not fused to the outer surface of the branch wire 4 disposed on the self-bonding layer 12 of the non-folded portion 10a of the cushion sheet 10, and the cushion sheet 10 is connected to the trunk 3 of the wire harness. The cushion sheet 10 itself can be easily and reliably removed from the wire harness 1 because the cushion sheet 10 itself is not fixed by an adhesive tape or the like.

  On the other hand, when the optional component is not mounted and the connector 5 is disposable, it remains mounted on the trunk 3 of the wire harness with the connector 5 housed in the bag 15 of the cushion sheet 10. Also in this case, since the bag 15 has the self-bonding layers 12a and 12b on the upper and lower inner surfaces bonded together, the connector 5 does not jump out of the bag 15 and is stably held. Further, when peripheral parts interfere with each other in the vehicle, the cushion sheet 10 can be brought into contact to prevent the occurrence of a collision noise, and the cushion sheet 10 can absorb the vibration noise caused by the vibration of the connector 5 to reduce the occurrence of abnormal noise. .

FIG. 5 shows a second embodiment.
In the second embodiment, when it is determined that the optional component 5 is not mounted on the vehicle and the optional connector 5 is disposable, the bag 5 is accommodated in the bag 15 of the cushion sheet 10. The adhesive tape 20 is wound around the outer peripheral surface of 15 to the outer peripheral surface of the trunk line 3 of the wire harness 1.

  Even when the cushion sheet 10 is wound around the main line 3 with the adhesive tape 20 as shown in FIG. 5, it is necessary to mount optional components later and take out the connector 5 in the bag 15 of the cushion sheet 10. May occur. In this case as well, until the optional parts are mounted, the connector can be pressed from above the cushion sheet by wrapping the adhesive tape to reduce variations in the connector mounting position and mounting direction, and the connector can be stably held. In addition, the cushion sheet 10 can be detached from the wire harness main line 3 simply by cutting the adhesive tape 20 when connecting the optional component and the connector 5. The connector 15 can be taken out by cutting off the bag 15 of the detached cushion sheet 10, and the adhesive tape 20 does not remain on the connector 5.
