0002

[Conventional technology]

For example, a tarpaulin installed between the main body of the telephone and the handset, or between the main body of the telephone and a wall, etc. The terminals are connected by cords, but there are no cords at these electrical connection points. A modular product with internal conductive terminals that are crimped onto a conductive member to form an electrical contact. - An electrical connector that engages a plug and a modular jack to make an electrical connection. (hereinafter simply referred to as a connector) is commonly used.

0003 FIG. 6 shows an oblique view of an example of such a conventional connector, that is, a modular connector. This is a perspective view, in which A is the plug of the connector, and the housing B has conductive terminals. A plurality of vertical grooves D into which the grooves C are inserted are provided. Figure 7 shows that this vertical groove is also partially broken. This vertical groove D has a lower end communicating with the cord hole E and an opening. are doing. In addition, each of the multiple cords F from which the insulation coating has been peeled off is a cord. A conductive terminal C made of a metal plate is inserted into the hole E and press-fitted into the vertical groove D from above as shown in FIG. By press-fitting its tip (lower end in FIG. 7) into the cord F, the connector is This constitutes the electrical contacts of the connector.

0004 The conventional conductive terminal C used here has the same shape on both sides of the tip. It has two sharp-shaped contact portions G, and these contact portions G are shown in FIGS. 8 and 9. Press-fit the cord F made of a single conductor as shown in the figure, and insert the cord F into the cord. The cord F is fixed in the cord hole E, and an electrical connection is made between the cord F and the conductive terminal C. .

[0005]

[Problem that the idea aims to solve]

In such a conventional conductive terminal C, there is a cord between the contact portions G and G at the tip. There is no problem if the door F is held correctly as shown in FIG.

[0006] However, if the code F between the contact parts G and G is thick as shown in Figure 10, If they are held in a misaligned manner, the tips of these contact portions G, G are sharp, so the As shown in the figure, the cord F is cut off by the contacts G, G.

[0007] Therefore, even if the conductor of code F has a single wire structure, if it becomes as shown in Figure 11, Contact had become unstable. In the case of a cord with a twisted wire structure, the twisted thin conductor is the contact point. If the parts G and G are press-fitted, they are likely to be cut, resulting in poor continuity. Also , in the case of a cord with a structure in which copper alloy foil is wrapped around the core material, the copper alloy foil is attached to the contact parts G and G. It is easy to cause poor conductivity due to peeling from the core material due to press-fitting.

[0008] For this reason, the conventional conductive terminal C is easy to apply to cords with a single wire structure, but It is difficult to apply to cords with a stranded wire structure or a structure in which copper alloy foil is wrapped around a core material.

[0009] Furthermore, in the above-mentioned conductive terminal C, the contact portions G, G are provided one on each side. Since there are only a few wires in contact with the cord, there are few parts that come into contact with the cord, so even if it is a single wire, it is especially In addition, in the case of cords with thick core wires, poor contact is likely to occur.

0010 Furthermore, in the above-mentioned conductive terminal C, since both contact portions G, G are sharp, there is a possibility of breakage. Easy to do.

[0011] This invention was developed in view of the above circumstances, and is limited by the structure and thickness of the cord. It can be applied to various types of cords without any problems, and the contact condition between the contact part and the cord can be adjusted. A conductive terminal that is stable and does not cause conduction defects, and the contact part is difficult to break. is intended to provide.

It is characterized by being lower than the protruding height of the part and having a sharp tip. be.

[0013]

[Effect]

Since the tips of the first and second contact portions on both sides of the tip of the conductive terminal are non-sharp, these 1. Even if the second contact part comes into contact with the cord, the cord may be cut or the copper alloy foil may It will not peel off from the core material. In addition, a Since the third contact portion also contacts the cord, the contact state is stabilized.
