Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-core cable laying device, and in particular, lays a core wire of a multi-core cable in a wire laying groove of a connector housing having various shapes and sizes to identify the extra length of the core wire. The present invention relates to a multicore cable laying device capable of sequentially performing the work of cutting and then press-connecting a connector body to the connector housing in the same device.

[0002]

2. Description of the Related Art A conventional multi-core cable laying device holds a multi-core cable and a connector housing, and a wire laying jig which is a wire laying position indicating means for instructing a wire laying position of a core wire of a multi-core cable. A housing holder is provided, and by moving either the wiring jig or the housing holder, the tip of the wiring jig indicates the wiring position of the connector housing corresponding to a specific core wire, Is to be laid out. When the core wire is laid, an operator preliminarily lays the core wire and then press-fits the core wire by using a press-fitting mechanism portion in the multi-core cable wiring device. Further, the extra length of the laid core wire is cut by the extra length cutting mechanism section. Subsequently, the connector main body is press-contacted to the connector housing by a separate connector press-contacting device.

Due to the difference in the shapes of the connector body and the connector housing, the connector body and the connector housing are pressure-contacted to each other by a vertical pressure contact type in which the connector body is pressure-contacted from the vertical direction to the connector housing in which the core wire is laid. There is a horizontal pressure contact type in which a connector housing having a core wire is pressed against the connector body from the horizontal direction. Further, the connector housing may be U-shaped or I-shaped.

[0004]

In the prior art, a connector pressure welding device must be provided separately from the multi-core cable wiring device, the core wire is press-fitted and wired, and the extra length of the core wire is cut. It is necessary to remove the connector housing from the multi-core cable laying device, attach it to the connector crimping device, and then crimp the connector body. For this reason, there is a problem that when the cable is removed from the multi-core cable wiring device, the wired core wire comes off from the wiring groove. Since the extra length has already been cut off from the core wire that has come off in this way, there is no extra length, and if the worker manually re-wires it,
There is a problem in that the core wire is insufficient in the designed length and tends to be a defective product.

There is a fully automatic wiring device, but there is a problem that its structure is complicated, heavy and large, and the wiring device becomes very expensive. Further, there is a problem that it is not possible or difficult to wire various types of connector housings with the same device due to the difference in the pressure welding method and the difference in the shape of the connector housing. For example,
In a device for laying a core wire on a housing composed of a pair of I-shaped connector housing halves as shown in FIG. 5, the connector housing halves are divided and arranged in parallel and at a predetermined interval, It is arranged so as to hold the core wire between them. However, when laying a core wire on a U-shaped connector housing as shown in FIG. 4, the above-described device cannot be used. Further, when the core wire is laid in the U-shaped connector housing, the core wires must be aligned and inserted in a line in the gap opened in the central longitudinal direction. There is a problem that it is very time-consuming and mass production is virtually impossible.

As described above, the connector body and the connector housing can be pressure-contacted by the vertical pressure-contact type and the horizontal pressure-contact type. Since the directions in which the force at the time of pressure-contact is applied are different, they must be pressure-contacted in the same device. However, since each requires a dedicated device, a plurality of types of devices must be provided, the installation place is restricted, and the cost becomes high.

The object of the present invention is to solve the above-mentioned problems of the prior art and to cope with various types and structures of connectors and connector housings, work for identifying the core wire of a multi-core cable, and extra length of the core wire.

b and the like are omitted for the sake of clarity.

At the time of actual wiring work, as a starting position for wiring and assembling work of the vertical pressure contact type connector, first, as shown in FIG. 7, first provisional wiring grooves 36a, 36b of the dentures 22a, 22b are first shown. So as to incline about 45 degrees with respect to the common plane, the link connecting pins 28a, 28b provided on the lower arm portions of the denture mounting members 24a, 24b are pulled down by a link mechanism (not shown), and the comb teeth 21a, 2
The angle with respect to the denture mounting members 24a and 24b is adjusted and fixed so that the second provisional wiring grooves 35a and 35b of 1b are substantially horizontal. At this time, the rows of the second provisional wiring grooves 35a and the first provisional wiring grooves 36a, and the rows of the second provisional wiring grooves 35b and the first provisional wiring grooves 36b, which are respectively aligned in a straight line, are half. For example, the fine adjustment mechanism adjusts so that the pitches are shifted.

As shown in FIG. 7, the core wire 32 is tensioned through the second temporary wiring groove 35a and the first temporary wiring groove 36a, and the second temporary wiring groove 35b and the first temporary wiring groove 36b. Do the temporary line. The temporary wiring work is performed, for example, by the applicant of the present invention, including Japanese Patent Application No. 5-29596 and Japanese Patent Application No. 5-29597.
The core wire 32 is identified by the same method as the identification wire disclosed in "Core wire identification wire laying device for multi-core cable" and the like, and the tips of the wire guides 30a and 30b are laid according to the identification result. This can be done by indicating the position of the groove to be provided and temporarily laying the core wire 32 in the indicated groove.

When the provisional wiring is completed, as shown in FIG. 8, the ridge teeth 22a and 22b and the comb teeth 21a and 21 are formed.
In order that the tooth surfaces of b face each other and almost come into contact with each other, a link mechanism (not shown) is used to form the denture mounting members 24a, 2b.
4b is rotated, and the comb tooth attachment members 23a, 23b are rotated about the rotation shafts 27a, 27b. This allows
One plane in which the core wires 32 temporarily laid in the first and second temporary wire grooves 35a and 36a and 35b and 36b are alternately arranged in a row, and substantially include the facing contact surfaces of the respective comb teeth (the common plane). ) Are aligned. The U-shaped connector housing 41 as shown in FIG. 4 inserts the aligned core wires 32 into the gap so that the comb teeth 21 are formed.
a, 21b and the dentures 22a, 22b are inserted from the rear side forward along the side surfaces (the upper surface in the figure) of the denture teeth 22a, 22b, and The wiring grooves 48a, 48b are positioned so as to correspond to one groove, and the comb teeth 21a, 21b and the comb teeth 22a, 22 are positioned.
b and fixed to at least one of these mounting members,
Is loaded. The positioning is performed, for example, by the comb tooth mounting member 23
This is performed by bringing the opening end side of the connector housing 41 into contact with the rear surface of a and 23b.

Subsequently, as shown in FIG. 9, the comb teeth 21a and 21b are placed outside each other while the core wire 32 that is temporarily wired is held by the second temporary wire grooves 35a and 35b of the comb teeth 21a and 21b. Then, the core wire 32 is permanently wired in the wiring grooves 48a and 48b of the connector housing 41. At this time, since the connector housing 41 is U-shaped,
Since the opening end side may be opened and deformed or damaged in an extreme case, for example, the opening end side may be clamped by a U-shaped jig or the like, or the comb tooth mounting member 23 may be used.
It is desirable to prepare an appropriate stopper on the rear surface of a and 23b. As described above, the core wire 32 can be laid in the U-shaped connector housing 41. Next, as shown in FIG. 3, the connector main body 40 is loaded and held in the connector holding portion 4 ′ of the pressure contact block 4, and the pressure contact limiting rod 44 is pulled out from the rod holding portion 45 to vertically move the connector main body 40.

In order to bring the two objects into a predetermined relative position in a state where they are in contact with each other, as described above, for example, after the wiring base 2 is retracted and comes into contact with the press contact base 3, the wiring base is further moved. It is preferable that the spring 2 is slightly retracted against the repulsive force of the spring so that the press-fitting base 3 receives the repulsive force of the spring.

Then, by depressing the pressing handle 5, the connector body 40 held by the connector holding portion 4'is temporarily pressed against the connector housing 41. In this temporary pressure welding, the core wire 32 is cut into the wiring grooves 48a, 4a when cutting the extra length.
It is intended to prevent it from coming off from 8b. Further, the press contact limiting rod 44 functions as a stopper for preventing the main contact of the connector body 40 with the connector housing 41.
In this way, the housing holder 25 is further retracted in the state of being temporarily pressed, and the surplus length of the core wire 32 laid in the connector housing 41 is cut while pushing up by the surplus length cutting cutter 6. After the completion of cutting, the wiring base 2
When is moved forward, the biasing force applied to the press contact table 3 disappears, so that the contact state between the two is released. After the press-contact limiting rod 44 is removed from the vertical groove 49 of the connector body 40, the press-connecting handle 5 is sufficiently pushed down to fully press-connect the connector body 40 to the connector housing 41. As described above,
The vertical pressure contact type connector body 40 and the U-shaped connector housing 41 can be assembled.
