Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is utilized in the technical field of attaching cables to connectors, and particularly relates to an apparatus for inserting a cable to be connected by pressure welding into a cable holding groove of a connector.

[Conventional technology]

As this type of device, one disclosed in Japanese Patent Laid-Open No. 182988/1988 is known. In this known device, a plurality of cables are inserted in parallel between a pair of vertical rollers with a gap equal to the thickness of the cables, and each cable is fed out from the end of the roller by a pushing member from above. A disk having a groove for receiving one cable at one location on the outer circumference is disposed close to the end of the roller, and the cable is passed through the groove each time the disk rotates once.

Further, below the pair of vertical rollers, a pair of horizontal rollers are arranged to pinch and pull the cable.

On the other hand, the disk is provided with an arc-shaped hole near the outer periphery, and V
A transfer arm having a groove at its tip passes through the hole and reciprocates. At a lateral position of the tip of the transfer arm when the transfer arm moves forward, a connector is disposed so as to be movable for each pitch, and a multi-core cable is held near the connector.

In such a known device, a cable is inserted into the socket when the groove of the disc coincides with the end of the mass roller, and the cable is brought into position by the rotation of the disc by half a turn. Then, the tip of the cable is pinched by the horizontal rollers and pulled downward, so that it extends in the diametrical direction of the disk. Here, when the transfer arm advances through the hole in the disc, the V-shaped groove locks the cable and brings it to a predetermined position. At this position, the cable is inserted into a predetermined cable holding groove of the connector by means of an insertion member disposed laterally. At this time, the connector is adapted to move so that a predetermined cable holding groove is aligned with the stroke line of the pushing member based on a detection signal of the wire of one cable taken out by the disk.

[Problem to be solved by the invention]

However, in the above-mentioned known device, the cable inserted into the groove of the disc is delivered to the lateral roller by the hanging portion of the tip of the cable.

Therefore, if the cable tip is not long enough or has a curl, it may not be held by the horizontal rollers, and the transfer arm will not reliably bring it to the connector position. Moreover, this movement of the cable by the transfer arm does not ensure that the cable is brought to a position corresponding to the predetermined cable retention groove of the connector.

In addition, in the above-mentioned known device, the holding position of the multi-core cable must be at the longitudinal extension position of the connector, so the connector with cable as a product is an asymmetric type in which the multi-core cable is not located in the center of the connector. Therefore, a special connector case must be prepared.

The invention aims to solve the above-mentioned problems and to provide a device for attaching cables to connectors that is extremely reliable in terms of movement and position.

[Means to solve the problem]

According to the present invention, the above object is to provide a device for sequentially inserting each cable of a multi-core cable, which is a bundle of a plurality of coated cables, into a connecting part of a contactor or a comb-shaped cable holding groove of a connector. , a connector holder that holds the connector at a position where the connection part of the contact or the cable holding groove is exposed; a multi-core cable holder that holds the multi-core cable at a side position of the connector holder; A comb-shaped guide means with a guide groove at a position corresponding to the connection part of the held connector or the cable holding groove is provided on the side part, and a comb-like guide means is provided on one side of the block body with a width corresponding to the cable diameter.

■ First, - distribute each coated cable of the bundled multi-core cable, hold the multi-core cable in a predetermined position with a multi-core cable holder, and then block each cable in an arbitrary order. They are stored in parallel in the housing groove of the body. In this case, the cables closest to the opening of the cable carrying groove are covered with the lower surfaces of the carrying body and the cable holding means to prevent them from jumping out.

(2) Next, only the uppermost cable is inserted into the conveying groove by being pressed by a pressing member from below. Thereafter, when the conveyor moves forward while slidingly contacting one surface of the block body, the cable that is in contact with the conveying groove is conveyed while being retained in the conveying groove, and brought into the receiving groove of the cable receiving means.

(2) Next, the two pairs of finger bodies approach each other and enter the recess provided in the cable receiving means to clamp the cable.

(2) As a result, the blade section of one of the finger bodies, which is the detection contact means, bites into the cable sheath and comes into contact with the core wire, thereby determining the core number. Thereafter, the movable body moves the finger body to the position of a predetermined cable holding groove set corresponding to the above-mentioned core wire number of the connector.

(2) While the two pairs of finger bodies are moving to the predetermined position mentioned in (2) after exiting the recess, the two pairs of finger bodies perform a separating operation to tension the cable. At this time, when the finger body exits the recess and takes out the top cable from the recess, the cable is held down by the cable holding means and taken out around its front edge, so that the next cable is taken out. There is no possibility that the finger body will become tangled and float and interfere with the operation of the finger body.

■ The cable brought by the two pairs of finger bodies onto the contact portion of a predetermined contact of the connector or the cable holding groove and the guide groove of the guiding means corresponding to the holding groove is moved to the contact portion or the cable holding groove by the cable pushing member. Pushed into the cable retention groove. In this way, each cable is sequentially pushed into the contact portion or cable holding groove to complete the installation of all the cables.

The blade part 24B' forms a detection connection means that bites into the cable sheath and comes into contact with the core wire, and is insulated from the arm body 23 via an insulating member 27 as shown in FIG. (not shown), so that the number line of the cable can be determined when it comes into contact with the core wire of the cable. Further, the other finger body 25 is provided with a semicircular recess 29 for slidably holding the cable in a fixed position. The finger body 25 is slidable on the lower surface of the arm body 23 by a cylinder (not shown) so that the distance can be freely changed with respect to the other finger body 24 in a hanging state.

In this embodiment as described above, the connector is attached to the cable holding groove in the following manner.

■ First, a predetermined length of the outer sheath or tube at both ends of the multi-core cable P, which is made by bundling a plurality of cables with an outer sheath or tube, is removed, and each cable W is dispersed for attachment to the device of this embodiment. Be prepared. Next, the outer sheath (or tube) portion of the multi-core cable P is held in a predetermined position by the cable holder 7. Then, each cable W is inserted into the accommodation groove 9 of the block body 8. During this insertion, the carrier 11 is forcibly moved backward in the negative X direction, and the guide plate 16B is located at the upper position and together with the guide plate 16A forms a V-shaped groove that facilitates cable insertion. are doing. When the above-mentioned forcing force is released after the insertion of all the cables is completed, the conveying groove 12 is exactly located at the position of the above-mentioned accommodation groove 9.

■Next, the pressing body 10 in the accommodation groove 9 of the block body 8,
The cables are pushed up by a spring or the like, so that only the uppermost cable is inserted into the conveying groove 12 of the conveying body. After that, the conveyor 11 moves forward in the X positive direction. Then, at the forward position, that is, at the position where the conveying groove 12 of the conveying body 11 coincides with the receiving groove 14 of the block body 8, the conveying body 11 is temporarily stopped and the cable is held in a fixed position. At this point, the cable holding member 11A is positioned above the uppermost cable.

(2) Next, while the conveyance body 11 is stopped, the two finger bodies 24 and 25, which were waiting close to each other on the concave part 15 of the block body 8, descend into the concave part 15 with their legs spread apart. Clamp the above cable. As the finger body 24 is held, the blade portion 24B' of the finger body 24 comes into contact with the core wire of the cable, and the number wire of the cable is detected. Thereafter, the carrier 11 is moved back and the finger bodies 24 and 25 can freely take out the cable.

■ The finger bodies 24 and 25 (moving body 20) rise to take out the cable. At that time, when the finger bodies 24, 25 are raised, the uppermost cable is removed from the cable holding member 11.
The cable is taken out by sliding around the front edge of A, and the cable below it is held down by the cable holding member 11A to prevent it from becoming entangled with the uppermost cable and floating up. After that, the finger body 24.
25 move in the XY plane to bring the clamped cable onto a predetermined cable holding groove of the connector holding block C1 (or C2) while making the distance between them a little wider and tensioning the cable. That is, when the cable is in the cable holding groove, one finger body 25 is attached to the connector C1.
, and the other finger body 24 is located at the other side of the connector C1. Thereafter, the push-in piece 26 is lowered to the extent that it lightly contacts the upper surface of the cable. Further, at this time, the above-mentioned movement is performed by a command from the control means as a set coordinate distance corresponding to the cable number detected by the blade part 24B'.

(2) Next, the finger bodies 24, 25 (moving body 20) are lowered by a set distance, and the cable is inserted into a predetermined guide groove of the guide body IA. Then, the push-in piece 26 is inserted into the cable holding groove of the connector C1 while pressing the upper surface of the cable.

■ In this way, the attachment of the - cable to the connector cable holding block is completed, and the above steps are repeated for the other cables in sequence. After all the cables W have been attached to the cable holding block, a pressure welding machine (not shown) prepared elsewhere connects the cable holding block to the connector body block (not shown) in which a plurality of contacts are implanted. ), and each cable and contactor are electrically and mechanically connected.

(2) As described above in (1) to (3) above, while one unit is wiring the cable within the device frame, the other unit is pulled out of the frame and the cable is attached.

■ Thus, in this way - cables are attached to the connector holding block C1 or C2.

Repeat the above process for other cables in sequence.
Then, the connector is connected to the cable by the pressure welding machine, and the connector is connected to both ends of one multi-core cable, thereby completing the process. In this case, since the cables are stretched straight in the area of the guide body IA, the cables are not bunched up irregularly or entangled with each other, so that post-processing of the connector can be carried out very easily.

Next, a second embodiment of the apparatus shown in FIG. 3 will be explained.

In this embodiment, the movable table 50 is Y as in the previous embodiment.
It is possible to move in the direction, but it is also possible to take it out from the device at the same time.

The installation base 51 mounted on the movable base 50 is shaped like a "U" on the movable base 50, and holds the connector C3 on each side. In the previous embodiment, a connector holder was provided on the installation base, but in this embodiment, a holding groove is provided directly on the installation base 51 to hold the connector C3 there. Of course, it is also possible to employ a connector holder as in the previous embodiment.

On both sides of each side of the installation stand 51, comb-shaped guide bodies 52, 52 having guide grooves are attached at positions corresponding to connector connection parts or cable holding grooves. In the previous embodiment, the guide bodies were provided only in one example of the connector, but in this embodiment, the guide bodies 52, 52 are located on both sides of the connector C3 as described above.

Approximately in the center of the space surrounded by the U-shaped installation base 51 are two blocks 5 that are movable relative to each other in the X direction.
A multi-core cable holder 53 consisting of 3A and 53B is provided. A V-shaped groove 53A' is formed in one block 53A, in which a multi-core cable (not shown) is held.

A block body 54 is installed on the moving table 50 at a position on the open side of the U-shaped installation table 51. The block body 54 has three receiving grooves 55, 55, 55 formed therein, and receiving grooves 56, 56, 56 are provided in the upper part thereof at positions in the negative X direction relative to the receiving grooves 55, 55, 55, respectively. There is. Further, recesses 57, 57, 57 are also formed perpendicularly to these receiving grooves 56, 56, 56.

In the device of this embodiment, the multi-core cable is held by the multi-core cable holder 53, and each cable extending from the tip from which the outer sheath has been removed is inserted into the accommodation groove 55, 55, 5 as appropriate.
It can be placed in any of 5. In this case, it is preferable to select the accommodation groove so that the cables do not become entangled with each other when accommodated in the accommodation groove. Next, the cables in each storage groove 56, 56, 56 are sequentially taken out one by one using the same carrier, cable holding means, and finger body (all not shown) as in the previous embodiment, and Push into the predetermined cable holding groove of connector C3. The cable is then held by two guides 52, 52 on either side of the connector.

In this embodiment, compared to the previous embodiment, there are a plurality of accommodation grooves, so the number of cables in one accommodation groove is reduced, and as a result, the load on the pressing body in the accommodation groove is reduced. Since the cable is held on both sides of the connector by the two guide bodies 52, 52, there are advantages such as eliminating the possibility of the cable twisting up on one side of the connector and eliminating obstacles in the movement of the finger bodies.

In the above two embodiments, the cable is inserted into the cable holding groove provided in the connector cable holding block, but the present invention is not limited thereto. It is also possible to connect the cable directly to the connection part of the child (for example, by pressure welding, etc.).

〔Effect of the invention〕

As described above, in the present invention, the cable is brought to the predetermined position of the cable holding groove of the connector under tension by the finger body and attached with the push-in piece, so that the cable is reliably held and taken out and placed in the predetermined position. This has the effect of improving the reliability of work. Furthermore, branch connections can be made to a plurality of connectors, increasing diversity.

In addition, the cable holder prevents the cable from lifting when it is taken out, thereby avoiding problems with the operation of the finger body, and the cable after the cable is connected has a straight part provided by the guide means, making post-processing extremely easy. As a result, the reliability and efficiency of the work can be further improved.
