Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for connecting a multicore connector in which a plurality of conductive contacts are assembled into an insulator.

[Prior Art] In a conventional multi-conductor connector, the cable core wires are crimped to a plurality of contacts one by one, and then the contacts are assembled into an insulator for connection. Note that the contact is usually attached to the insulator by grasping the cable with fingers and pushing the contact into the inside of the insulator.

[Problems to be Solved by the Invention] However, crimping the core wires of the cable to a plurality of contacts one by one is not preferable because the crimping operation becomes multi-step.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for terminating a multicore connector in which the number of crimping steps is reduced.

[Means for Solving the Problems] According to the present invention, a method for connecting a multi-core connector in which a plurality of conductive contacts are assembled into an insulator includes a preparation step of preparing a plurality of the contacts, and a preparation step as described above. A crimping step in which the core wires of the cable are matched one-to-one with the plurality of contacts prepared in the step and crimped all at once, and a mounting step in which the plurality of contacts prepared in the preparation step are attached to the insulator. A method for connecting a multi-core connector is obtained.

[Embodiment] FIG. 1 schematically shows a method of connecting a multi-core connector according to an embodiment of the present invention.

Referring to FIG. 1, this multicore connector includes a plurality of conductive contacts 1 and an insulator 5 into which these contacts 1 are incorporated. The contact 1 is connected to a multicore flat cable 3 by crimping.

The contact 1 has a crimp portion 7 in the middle portion in the longitudinal direction;
A contact portion 9 extending to one side of the crimp portion 7 is formed. A holding portion 11 is formed on the other side of the crimp portion 7, that is, on the opposite side of the contact portion 9. The contact portion 9 is, for example,
This is a part into which a conductive mating contact (not shown) such as a pin contact is inserted or removed while in contact. The crimping part 7 is a part that crimps the core wire 15 of the cable 3 and thereby electrically connects the core wire 15 to the contact 1. The holding portion 11 is a portion that holds a covering portion corresponding to each core wire 15 of the cable 3.

The contact 1 is made by punching out a thin conductive plate and then bending it. These contacts 1 are assembled inside the insulator 5 so as to be arranged parallel to each other.

A plurality of elongated holes 13 are formed inside the insulator 5 to accommodate the contacts 1.

The contact 1 is inserted into the long length 13 of the insulator 5 with the contact portion 9 at the beginning.

The method of connecting the contact 1 and the cable 3 will be explained below.

First, in a preparation step, a plurality of contacts 1 are prepared. The number of contacts 1 to be prepared at this time is cable 3.
It is desirable that the number of cores be the same as that of .

Next, as shown by symbol A in FIG. 1, the core wires 15 of the cable 3 are made to correspond one-to-one to the plurality of prepared contacts 1. By crimping the crimping part 7 and the holding part 11, a plurality of contacts 1 can be formed as shown by symbol B in FIG.
are collectively electrically and mechanically connected to the cable 3. In this way, the crimping process is performed.

Thereafter, the mounting process is performed by inserting the plurality of contacts 1 at once into the plurality of elongated holes 13 of the insulator 5 in one-to-one correspondence. In this state, the contact 1 is fixed by engaging with the inner wall of the insulator 5.

Note that after attaching a plurality of contacts 1 to the insulator 5, the cables 3 may be crimped to all the contacts 1 at once. Figure 2 shows a method to more completely fix the contacts 1 attached to the insulator 5. Another example is shown. In this embodiment, the same parts as in FIG. 1 are denoted by the same reference numerals, and the explanation thereof will be omitted.

Referring to FIG. 2, after the contact 1 is mounted on the insulator 5, the plate-shaped adhesive retainer 17 is inserted into the groove 16 which is widened so as to face the plurality of elongated holes 13 of the insulator 5. Flexible engaging portions 19 are formed at both ends of the retainer 17 . The engaging portions 19 serve to prevent the retainer 17 from being removed by entering the engaging holes 23 formed in both side walls 21 of the insulator 5.

Note that if the number of contacts 1 to be attached to the first insulator 5 is extremely large, the contacts 1 may be divided into several groups and the cables 3 may be crimped together for each group.

[Effects of the Invention] As described above, according to the connector connection method of the present invention, a plurality of contacts are crimped to a cable at once, so the number of steps required for crimping work is reduced.
