  For example, various instruments such as speedometers, tachometers, water temperature gauges, and fuel gauges, and various warning lamps such as hydraulic pressure, voltage, and current are integrated into the opening of an instrument panel (hereinafter referred to as instrument panel) of an automobile. When a combination meter (hereinafter referred to as a combination meter) is attached, a part of the wiring harness routed inside the instrument panel is connected to a connector on the back of the combination meter, which is an electrical component. In this case, from the viewpoint of workability, it is necessary to provide a certain margin for the length of the wiring connected to the combimeter. However, since many parts such as air conditioning units, ducts, reinforcements, and other electrical components are placed inside the instrument panel, if the wiring connected to the combi meter is too long, other parts inside the instrument panel Interference with is a problem. If the wiring is excessively interfering with other components, the wiring may be worn by engine vibration and running vibration, which may cause problems such as disconnection and short circuit.

  For this reason, the wiring connected to the connector of the combimeter needs to be set to an appropriate length, and it is possible to check the interference state with other parts in a state where the combimeter is assembled to the instrument panel. desirable.

Further, the flexible arm 40 is flexible and can be bent freely to maintain its shape, and the jig connector 41 attached to the tip is positioned with a predetermined rigidity at an arbitrary position. be able to. The rigidity of the flexible arm 40 and the clamping force of the clamp portion 39 are appropriately set so as to have sufficient rigidity as compared with the meter harness 18 connected to the connector 13 of the combiometer 6.

  The jig connector 41 has a shape corresponding to the connector 13 of the combination meter 6 and can be connected to the connector 18 </ b> A of the meter harness 18.

  Using the positioning jig 19 and the wiring interference confirmation jig 36 configured as described above, assuming that the combination meter 6 is attached to the instrument panel 1, the meter harness 18 and other parts inside the instrument panel 1 Next, a method of confirming the interference state will be described.

  First, the positioning jig 19 is assembled to the combination meter 6 as follows. Loosen the thumbscrews 29, 30, 31 of the positioning jig 19 and move the slide block 21 on the guide rod 20, while engaging the engaging portion 27 with the mounting portion 14 of the combimeter 6, The pin hole 28 is aligned, and the pin 35 is inserted into these to position the slide block 21. In this state, the thumbscrew 29 is tightened to fix the slide block 21 to the guide rod 20.

  While moving the first and second arms 23, 25, the connector positioning opening 32 of the connector positioning section 26 is aligned with the connector 13 of the combimeter 6, and the positioning connector 33 is connected to the connector through the connector positioning opening 32. 13 and the connector positioning part 26 is positioned. In this state, the thumbscrews 30 and 31 are tightened to fix the first and second arms 23 and 25.

  Thereafter, the positioning pin 35 and the positioning connector 33 are removed, and the positioning jig 19 is removed from the combiometer 6. As a result, the inverted positions of the mounting portion 14 and the connector 13 of the combination meter 6 are transferred to the positioning jig 19.

  Next, the wiring interference confirmation jig 36 is assembled to the positioning jig 19 as follows. First, the lock screw 42 is loosened, the jig mounting portion 43 of the mounting block 38 is engaged with the engaging portion 27 of the jig 19 while the telescopic rod 37 is extended or shortened, and the jig bolt hole 44 and the pin hole are engaged. 28, and the mounting block 38 is positioned by inserting a pin 35 therethrough. In this state, the lock screw 42 is tightened to lock the expansion / contraction position of the expansion / contraction rod 37.

  Then, the jig connector 41 is fitted into the connector positioning opening 32 of the connector positioning portion 26 while the flexible arm 40 is bent. Thereafter, the positioning pin 35 is removed, and the wiring interference confirmation jig 36 is removed from the positioning jig 19 while removing the jig connector 41 from the connector positioning opening 32. Thereby, the positions where the engaging portion 27 of the slide block 21 of the positioning jig 19 and the connector positioning opening 32 of the connector positioning portion 26 are inverted, that is, the positions of the mounting portion 14 of the combimeter 6 and the connector 13 are changed. It is transferred to the wiring interference confirmation jig 36.

  Next, as shown in FIG. 1, the wiring interference confirmation jig 36 is attached to the opening 1 </ b> A of the instrument panel 1. At this time, the wiring interference confirmation jig 36 reproduces the shape and position of the mounting portion 14 and the connector 13 of the combimeter 6 accurately, so that the combimeter 6 is attached to the opening 1A of the instrument panel 1. Similarly, the connector 18 </ b> A of the meter harness 18 is connected to the jig connector 41, and the bolt 16 is inserted into the jig bolt hole 44 of the jig mounting portion 43 of the mounting block 38 to be attached to the opening 1 </ b> A of the instrument panel 1. be able to.

  Since the wiring interference confirmation jig 36 is a skeleton structure composed of the telescopic rod 37 and the flexible arm 40, the meter harness 18 can be easily accessed even when attached to the opening 1A of the instrument panel 1. Thus, the meter harness 18 can be actually moved in the instrument panel 1, and the interference state with other parts can be visually confirmed.

  The positioning jig 19 and the wiring interference confirmation jig 36 can freely move the slide block 21, the mounting block 38, the connector positioning section 26, and the jig connector 41 according to the positions of the mounting portion 14 and the connector 13 of the combination meter 6. Since it can be moved, versatility is high and it can respond to multiple types of instrument panel 1 and the combiometer 6. In this case, the wiring interference confirmation jig 36 adjusts the position of the mounting block 38 by using the telescopic rod 37 that can be expanded and contracted, so that the rod portion does not protrude outside the mounting block 38 and other parts. The structure is difficult to interfere with.

  In the above-described embodiment, the positioning jig 19 and the wiring interference confirmation jig 36 correspond to the single connector 13 of the combination meter 6, and the pair of first and second arms 23 and 25, Although one flexible arm 40 is provided, when the combimeter 6 is provided with a plurality of connectors, it can be dealt with by providing a plurality of arms.

  The positioning jig 19 and the wiring interference confirmation jig 36 have a degree of freedom to transfer and reproduce the positions of the mounting portion 14 and the connector 13 with respect to the instrument panel 1 with respect to the assumed type of combination meter 6. As for the confirmation jig 36, if it has a skeleton structure that allows access to the meter harness 18 connected to the jig connector 41 while being attached to the opening 1 </ b> A of the instrument panel 1, It may be a structure. Moreover, although the said embodiment demonstrated the case where the interference of the meter harness 18 was confirmed about the combimeter 6 using the positioning jig | tool 19 and the wiring interference confirmation jig | tool 36, this invention is other than this. The present invention can also be applied to the case of checking the interference of the wiring of an electrical component whose wiring is connected to the back surface portion of the audio, car navigation, or the like by a connector.
