DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for arranging a processed electric wire with terminals in the form of an actual wire harness after subjecting the electric wire with terminals to joint processing or terminal punching. The present invention relates to a detachable jig.

[0002]

2. Description of the Related Art FIG. 4 shows a conventional electric wire routing jig. The electric wire arranging jig 40 includes a wiring board 42 for arranging the electric wire 41, a holder 43 provided on the wiring board 42 for holding the electric wire 41, and a connector housing into which the electric wire 41 is inserted. And a support 45 for supporting 44.

[0003] A holder 43 for holding the electric wires 41 is U-shaped, and is fixed to a routing table 42 with bolts (not shown) to bundle the electric wires 41 or to branch the electric wires 41. The receiving member 45 for the connector housing 44 is fixed to a desired one of a plurality of holes 46 formed in the routing table 42 with a bolt (not shown), and supports the connector housing 44 into which the electric wire 41 is inserted.

[0004]

In the above-mentioned conventional example, since the holder and the receiver are respectively fixed to the routing table with bolts, the part number of the connector housing and the number of poles are different, and the branching of the electric wire is performed. According to the requirements of the difference of the exterior parts to be connected to the electric wire, etc., each time, re-arrange the holders and receiving devices etc. on one routing table and fix them with bolts, or
Must advance many fabricated wire-installing jig to satisfy the respective requirements, it is a problem there Rubakari that
Conventionally, bundled wires are bundled to form a wire harness.
After the manufacture, the continuity test of the connector is performed separately.
Therefore, there is a problem that it takes time and effort.

[0005] In view of the above, the present invention not only eliminates the need to manufacture a large number of jigs for wiring in advance, but also provides
It is another object of the present invention to provide an electric wire arranging jig capable of inspecting the continuity of a connector at the same time .

[0006]

In order to achieve the above object, an electric wire arranging jig of the present invention is fixed to an arranging stand, and
Has receptacle for connector housing with wire inserted
In the wire arranging jig, the receiving member may include the connector.
Housing receiving portion for the housing and the housing
Support the housing and secure the housing
And a housing fixed to the routing table at the
A column for supporting the receiving portion and a housing provided on the supporting portion;
And an engaging portion for detachably mounting the receiving portion.
A housing receiving portion for locking the connector housing.
Jig fastener and inserted into the connector housing
A test pin for the terminal and a connector connected to the test pin
A connection block for the connector.
It is characterized by having a lock.

[0007]

[Function] A receiving member for a connector housing in which an electric wire is inserted.
The fixture is divided into a housing receiving section and a supporting section,
The receiving part is not fixed to the routing table, only the support section is the routing table.
Fixed to Housing receiving part is supported by engaging part
It is easily removable. This allows the housing receiver
Only the receiving part is moved and inserted into the supporting part, and
Fixed to the table.

Further, since the housing receptacle has a test pin, if it is inserted the terminal all the connector housing <br/>, the connector enters the unit receiving housing,
The terminals in the connector come into contact with the inspection pins on the housing receiving part and become conductive, and if the terminals are not inserted into the connector housing ,
If the connector housing enters the housing receiving portion, it does not conduct , so the terminal
Insertion and non-insertion can be confirmed.
It can also be used as a continuity inspection tool for the connector.

By standardizing all but one, it is possible to easily adapt to the type and size of the connector housing.

The method of using the electric wire routing jig 1 will be described below. The form of the wire harness to be delivered is determined by the car maker, and since the wires are routed based on that shape, the positions where the wires are held on the routing table, the positions where the wires are branched, and the wires are inserted. Information on the type and size of the connector housing is obtained in advance. Accordingly, the routing table is provided with a large number of holes corresponding to these positions and the position where the housing receiver is to be fixed.

The supporting portion 9 is fixed on the routing table 4 with bolts 18 corresponding to the position where the electric wire 5 is held and the position where the electric wire 5 is branched, and is supported corresponding to the position where the housing receiver 21 is fixed. The part 20 is fixed with bolts 38.

When the electric wire 5 is routed according to the actual wiring harness wiring configuration, as shown in FIG.
The support 11 of the electric wire holding part 8 is inserted into the support part 9 fixed at the position where
As shown in FIG. 3B, the column 22 of the housing receiving portion 19 is inserted into the supporting portion 20 fixed to the position where the housing receiving portion 21 corresponding to the type and size of the connector housing 6 is to be provided.

The electric wire 5 is gripped by the electric wire locking portion 10 of the electric wire holding portion 8 and the connector housing 6 is inserted into the housing receiver 21 of the housing receiving portion 19, and the connector housing 6 is locked by the housing fastener 23. Projection 23a
And the connector housing 6 is fixed to the routing table 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 connector of the manufactured wire harness . According to the present invention, the connector housing 6 is inserted into the housing receiver 21 and fixed to the routing table 4 at the same time as the housing. The inspection pin 29 provided on the receiver 21 can determine whether or not the electric wire 5 inserted into the connector housing 6 is correctly inserted into a terminal housing (not shown) of the connector housing 6. That is, the wire arranging jig 1 can be used not only for arranging the wires 5 but also as a continuity inspection tool for the wires 5 with respect to the connector housing 6.
