Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention (Object of the Invention) The present invention relates to an easy manufacturing method for an electrical connector, and provides an inexpensive electrical connector.

<Prior art and its problems> Conventionally, as typified by Japanese Patent Application Laid-Open No. 59-143285, or as shown in FIGS. 5 and 6, electrical connector contacts 1' are made by rolling a thin plate. It has a male terminal portion 1a'.

As is clear from the figure, since the shape is complex, the developed shape of the material extraction must naturally be large, and the contact pitch is 1.
It was extremely difficult to press the terminal pitch of the electrical connector with the same dimensions as the terminal pitch.

Generally, the terminal pitch of an electrical connector is formed to be n times the contact pitch on the electrical connector (n is 2 or more), and the terminals are pressed into a reel shape, and the continuous terminal row is cut to a predetermined length. However, one row of terminal assembly work was completed by performing the assembly work n times.

As described above, there are disadvantages in that it is time-consuming and requires a large amount of pressed material.

<Object of the Invention> In order to solve these drawbacks, the present invention has been made with the aim of providing an inexpensive electrical connector using an easy manufacturing method for the electrical connector. In a connector contact, a main body part for press-fitting and fixing into an electrical connector is provided in the middle, and a male terminal of the same plate thickness as the main body part is bent at approximately 45 degrees and formed below the main body part. It has a connector for connection on the upper side, a connecting part is provided upward from the side of the connector, and is further configured to be fixed to the upper end of the connecting part by a carrier body connected in the horizontal direction, The present invention is characterized in that the pitch of the contacts is formed to be the same as the pitch of the terminals of the electrical connector, so that the contacts can be press-fitted into the electrical connector all at once.

<Configuration of the Embodiment> Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 3 is a perspective view of the contactor 1 of the present invention, and the main body portion 1b located in the middle is a portion that is press-fitted into and held by an insulator. After the male contact portion 1a is pressed to have the same thickness as the main body portion 1b, it is bent at approximately 45° with respect to the main body portion 1b, and is located below the main body portion 1b. A connector 1c for wiring is provided above the main body 1b. FIG. 2 shows the contactor 1 of the present invention, (a), (b) p (c
) are a front view, a side view, and a bottom view, respectively. As is clear from the figure, a connecting part 1d is provided at the upper end of the connector 1c so as not to interfere with the connector 1c from the side surface of the connector 1c, and is fixed to the upper end of the connecting part 1d by a carrier body connected laterally. The pitch of the contacts 1 is formed to be the same as the terminal pitch of the electrical connector 3.

In this embodiment, the connector 1c and the connecting portion 1d.

The carrier body 1e is made of main body 1 in order to improve workability.
A deformed material with a thickness thinner than b is used.

FIG. 1 shows a partial internal sectional view of the electrical connector 3, and shows a state in which the contacts 1 are press-fitted into the insulator 2.

In the figure, an example is taken in which there are two contacts 1, but the required number are press-fitted.

FIG. 4(a) shows the cross-sectional shape of the male contact portion 1a of the contactor 1 of the present invention, and each corner is provided with a crushing surface 1f.

FIGS. 4(b), 4(c), and 4(d) are connection state diagrams when various types of general female contacts 4 on the market are connected.

Fig. 4(a)' shows the male contact part 1a' of the conventional contactor 1'.
The cross-sectional shape of is shown. Figure 4(b)', (cl
' and (d)' indicate conventional examples, and (b) and (
It is a connection state diagram corresponding to c) and (d).

As is clear from the above components, the contactor 1 of the present invention
When assembling the electrical connector 3 into the electrical connector 3, cut out the carrier body 1e of the same length as the required length of the electrical connector 3, and insert the contacts into the insulator 2 of the electrical connector 3, which has terminal holding holes with the same pitch as the contacts. After the carrier body 1e is press-fitted all at once, the assembly of one row can be completed by cutting the carrier body 1e.

Other Modifications> Not limited to the embodiments described so far, for example, the shape, length, angle, thickness of the contactor 1 and the connector 1c, the shape of the terminal holding hole of the electrical connector, etc. are within the scope of the present invention. It goes without saying that this includes various modifications.

<Effects of the Invention> As explained above, the electrical connector according to the present invention has excellent workability and assemblability, and has the excellent effect of being easy to manufacture and providing an inexpensive electrical connector. Because it can be done, it has great industrial value.
