Abstract

PROBLEM TO BE SOLVED: To easily fix a holding jig and a housing receiving jig to a wiring stage and reduce the number of wiring stage by dividing the holding jig into a wire holding part and a retaining part, dividing a receiving jig into a receiving part for housing and a retaining part, and previously fixing only the respective retaining parts to the wiring stage. SOLUTION: When wires 5 are wired according to the wiring mode of a wire harness, the studs of wire holding parts 8 are inserted into retaining parts 9 fixed to positions where the wires 5 are held or divided. The studs of housing receiving parts 19 are inserted into retaining parts 20 fixed to positions where housing seats corresponding with the kinds and the sizes of connector housings 6 are arranged. The wires 5 are clamped by wire engaging parts of the wire holding parts 8, and the connector housings 6 are inserted into housing seats of the housing receiving parts 19. The connector housings 6 are engaged with engage protruding parts of housing fixing jigs 23. The connector housings 6 are fixed to the wiring stage 4. Thereby the holding jigs and the housing receiving jigs are easily formed.

[0004]

However, in the above-mentioned conventional example, since the holder and the receiver are fixed to the wiring stand by bolts respectively, the difference in the product number and the number of poles of the connector housing, and the electric wire. Depending on the requirements such as the difference in branching, the difference in exterior parts to be connected to the electric wire, etc. each time, re-arrange the holders and receivers on one wiring stand and fix them with bolts, or However, there is a problem in that a large number of wire arranging jigs that meet the respective requirements must be manufactured in advance.

In view of the above points, the present invention is capable of easily fixing a retainer, a receiver, etc., which are re-disposed on an installation stand, without producing a large number of wire installation jigs in advance. An object of the present invention is to provide a wire installation jig that reduces the number of installation bases.

[0006]

In order to achieve the above-mentioned object, the present invention provides a wire laying jig having a holding tool which is fixed to a wiring stand and holds an electric wire. An electric wire arranging jig comprising: an electric wire holding portion for an electric wire; a support portion for supporting the electric wire holding portion; Adopt tools. Further, in a wire routing jig that is fixed to a routing base and has a receiving member for a connector housing into which an electric wire is inserted, the receiving device locks the connector housing to a housing receiving portion for the connector housing. A fastener, a test pin for a terminal inserted in the connector housing, and a connector connected to the test pin, and a support part that supports the housing receiving part and has a connection block for the connector; and the housing receiving part. A wire arranging jig including a supporting column for supporting the wire and an engaging portion provided on the supporting portion is also used.

[0007]

In the first structure described above, the holder is divided into the electric wire holding portion and the supporting portion, and the electric wire holding portion is not fixed to the wiring base, but only the supporting portion is fixed to the wiring base. The wire holding portion can be easily attached to and detached from the support portion via the engaging portion. As a result, only the wire holding portion moves and is inserted into the support portion, and the holder is fixed to the wiring stand.

Further, in the second structure, the receiving member is divided into the housing receiving portion and the supporting portion, and the housing receiving portion is not fixed to the wiring stand, but only the supporting portion is fixed to the wiring stand. The housing receiving portion can be easily attached to and detached from the support portion via the engaging portion. As a result, only the housing receiving portion moves and is inserted into the supporting portion, and the receiving member is fixed to the wiring stand. Also, because the housing receiving part has the inspection pin, if all the terminals are inserted in the connector housing, when the connector enters the housing receiving part, the terminal inside the connector becomes the inspection pin of the housing receiving part. Contact is made and a continuity test is performed. If the terminal is not inserted in the connector housing, the continuity check is not performed even when the connector housing enters the housing receiving portion.

And the connector housing 6 is fixed to the wiring stand 4. In this way, the electric wires are routed according to the actual wiring form of the wire harness, the electric wires are bundled, and the wire harness is manufactured.

The next step is a step of inspecting the continuity of the manufactured wire harness connector. However, in the present invention, the connector housing 6 is inserted into the housing receiver 21 and fixed to the wiring stand 4, and at the same time, the housing receiver 21
It is possible to determine whether or not the electric wire 5 inserted into the connector housing 6 is correctly inserted into a terminal accommodating chamber (not shown) of the connector housing 6 by the inspection pin 29 provided in the connector housing 6. That is, the wire wiring jig 1 can be used not only for wiring the wires 5 but also as a continuity inspection tool for the wires 5 with respect to the connector housing 6.

[0025]

As described above, according to the present invention, the holder can be separated into the wire holding portion and the supporting portion. Therefore, if the supporting portion is fixed to the wiring base in advance, the wire holding portion can be moved. The holder can be easily formed by simply inserting the supporting member into the supporting portion. Accordingly, it is possible to easily deal with the place where the electric wire branches by moving only the electric wire holding portion, and it is possible to reduce the time and labor for fixing the holding tool to the wiring stand.

Further, since the receiving member can be separated into the housing receiving portion and the supporting portion, if the supporting portion is fixed to the wiring base in advance, the housing receiving portion can be moved and inserted into the supporting portion. The housing receiver is easily formed. As a result, it is possible to easily deal with various types of connector housings only by replacing the housing receiving portion, and it is possible to reduce the time and labor for fixing the housing receiving member to the wiring stand.

Furthermore, at the same time when the connector housing is inserted into the housing receiving portion, the conduction state of the terminal with respect to the connector housing is inspected by the inspection pin.
The step of inspecting the terminals in the connector housing can be omitted. As a result, the number of steps can be reduced and the cost of work equipment can be reduced.
