Description

Detailed Description of the Invention (Industrial Application Field) The present invention relates to a connector in which a continuous terminal in which a plurality of terminal parts are connected to a band-shaped connecting part is attached to a connector body having a plurality of terminal attachment parts. The present invention relates to a terminal mounting method.

(Prior art) Conventionally, as a technology in this field, for example, as shown in Fig. 2 (
There were methods 1) to (4). The configuration will be explained below using figures.

Figures 2 (1) to (4) show the conventional connector terminal mounting process; Figure 2 (1) is a plan view of a continuous terminal;
) is a front view of the continuous terminal, (3) is a cord connection diagram, and (4) is a terminal installation diagram.

First, use the continuous terminal 1 as shown in Fig. 2 (1) and (2). In this continuous terminal 1, a plurality of cord connecting parts 1b and terminal parts 1C are arranged at approximately the same pitch P in a strip-shaped connecting part 1a.
1, and a plurality of feeding slots 1d are provided in the connecting portion 1a.

Since the continuous terminal 1 is made by punching out, for example, a band-shaped metal plate using a press or the like, the pitch P1 cannot be lower than a certain value.

Such a continuous terminal 1 is loaded into a crimping machine 2 between an upper mold 2a and a lower mold 2b as shown in FIG. 2(3).

After inserting the insulated cord 3 into the cord connecting part 1b manually or automatically, the upper mold 2a and the lower mold 2b bend the cord connecting part 1b into a gripping state and press it onto the cord 3. Separate the cord connecting portion 1b from the connecting portion 1a.

Each terminal portion 1C to which the cord 3 is connected and separated is attached to the connector body 4 as shown in FIG. 2(4). That is, the connector main body 4 has a plurality of thank-you or groove-shaped terminal mounting portions 4b arranged at substantially the same pitch P2 on substantially the same plane of an insulator 4a. Particularly in the case of the connector main body 4 having a large number of terminal attachment parts 4b, the pitch P2 is small in order to downsize the whole, and its size is smaller than the pitch P1 of the continuous terminals 1. The terminal mounting work is completed by manually inserting each of the terminal portions 1C one by one into each of the terminal mounting portions 4b having the pitch P2.

(Problems to be Solved by the Invention) However, in the connector terminal mounting method having the above configuration,
In the case of the connector main body 4 with a large number of terminal attachment parts 4b, the pitch P2 is smaller than the pitch P1 of the continuous terminals 1, so the plurality of terminal parts 1C to which the cords 3 are connected are connected to the connecting part 1a.
It is necessary to separate the terminals from each other and attach them one by one to each terminal mounting portion 4b, which requires a great deal of effort and time to assemble, resulting in a problem that manufacturing efficiency is low.

The present invention provides a method for attaching terminals to a connector that solves the problem of low manufacturing efficiency that the prior art had.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a connector main body in which a plurality of terminal mounting portions are arranged at substantially the same pitch on substantially the same plane of an insulator, and a strip-shaped A continuous terminal in which a plurality of terminal parts are connected at substantially the same pitch is used in the connecting part, and the parts between the terminals in the connecting part are bent at the same pitch as the pitch between the terminal attachment parts, and each of the terminal parts a step of connecting the cord to the connector body; a step of cutting the connecting portion to match the length of the connector body; and attaching a plurality of terminal portions connected to the cut connecting portion to each of the terminal attachment portions. The steps of separating the connected portions from the respective terminal portions after being attached are performed every j1 time.

(Function) According to the present invention, since the connector terminal mounting method is configured as described above, pitch alignment with the connector main body side is performed by bending the connecting portion, and in a subsequent process, the plurality of terminals connected to the connecting portion are To simplify and facilitate work when attaching individual terminal parts to each terminal attaching part of a connector body. Therefore, the above-mentioned problem can be eliminated.

(Embodiment) Figures 1 (1) to (6) are connector terminal mounting process diagrams showing one embodiment of the present invention, in which figure (1) is a plan view of a continuous terminal, and figure (2) is a plan view of a continuous terminal. Figure (1) is a front view, Figure (3) is a plan view of the continuous terminal after pitch adjustment, Figure (4) is Figure (3).

6) is a terminal installation diagram. Note that the same elements as the conventional elements in FIG. 2 are given the same reference numerals. The method of this embodiment will be explained with reference to these drawings.

(A) Manufacturing process for continuous terminals As shown in Figures 1 (1) and (2), for example, a band-shaped metal plate is punched out using a press or the like to form a band-shaped connection having a plurality of slots 1d for feeding. A portion 1a and a plurality of cord connecting portions 1 connected thereto at approximately the same pitch P1.
A continuous terminal 1 having a terminal portion 1C and a terminal portion 1C is made and prepared. The terminal portion 1C is either a male type or a female type, and the female type is shown in Figs. 1 (1) and (2).

(B) Pitch adjustment process for continuous terminals In order to match the pitch P1 between each terminal part 1C to the pitch when installing the connector body 4 side, a crimping machine or a press is used as shown in Fig. 1 (3) and (4). The bending portion 1e is formed by bending the portion between the terminal portions in the connecting portion 1a using a bending tool, and the pitch between each terminal portion 1C is set to P2.

(C) Cord connection process The continuous terminal 1 is loaded between the upper mold 2a and the lower mold 2b of a conventional crimping machine 2, for example, as shown in FIG. 2(3). After manually or automatically inserting the insulating cord 3 with the terminal part sheathed off into the cord connecting part 1b, the upper mold 2a and the lower mold 2b bend the cord connecting part 1b into a gripping state. 1. Crimp the cord 3 as shown in Figure 1 (5). The reason why the cord connecting portion 1b is bent is to increase the pull-out strength of the cord 3. At this time, the upper mold 2a and the lower mold 2
In some cases, the terminal portion 1C is press-molded into a predetermined shape in step b.

Note that there is also a method of crimping the cord 3 as it is to the cord connecting portion 1b without peeling off the coating on the end portion thereof.

In this case, the core wire of the cord 3 and the terminal portion 1C are electrically connected by subjecting the cord terminal portion to a treatment such as spot welding.

Such a cord connecting step may be performed simultaneously with the step (B) or before the step (8).

(D) Cutting process of continuous terminal The connecting portion 1a is cut to a predetermined length according to the length of the connector main body 4.

(E) For attachment to the connector body, prepare the process connector body 4. This connector body 4 is the first
As shown in FIG. 6, a plurality of thank-you or groove-shaped terminal mounting portions 4b are arranged at substantially the same pitch P2 on substantially the same plane of the insulator 4a.

Each terminal portion 1C connected by the connecting portion 1a is manually or automatically inserted into each terminal attachment portion 4b.

CF) Connection section separation process If the connection section 1a of the continuous terminal 1 is separated from each cord connection section 1b, the terminal installation work is completed.

This embodiment has the following advantages.

The pitch P1 between each terminal part 1C in the continuous terminal 1 is adjusted to the pitch P2 on the connector main body 4 side, and the plurality of terminal parts 1C to which the cord 3 is connected and connected at the connecting part 1a are connected to each terminal of the connector main body 4. Since the terminal part 1C is attached to the attachment part 4b, the attachment work of the terminal part 1C can be carried out easily and in a short time, and manufacturing efficiency is significantly improved.

Additionally, each process can be easily automated.

Note that the present invention is not limited to the illustrated embodiment, and various modifications are possible. For example, the steps (A) and (B) above may be performed simultaneously. The continuous terminal 1 may have a shape other than that shown, and the cord 3 may be electrically connected to the cord connecting portion 1b by soldering, spot welding, etc. without bending the cord connecting portion 1b. Further, the shape of the connector main body 4 can also be changed into various shapes.

(Effects of the Invention) As described in detail above, according to the present invention, the pitch between the terminal parts in the continuous terminals is adjusted to the pitch on the connector main body side, and the plurality of terminals connected to the connecting parts are connected to the connector main body. Since the terminals are attached to each terminal attachment part, the terminal part can be attached easily and accurately, and manufacturing efficiency is significantly improved.
