Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to improvements in electrical connectors.

(Prior Art) As a female type electrical connector, for example, one is known in which elastic clamping arms bent to have a substantially semicircular cross section are integrally provided on both sides of a substrate of an electrical contact portion. In this electrical connector, the spring force of the elastic clamping arm presses the mating electrical connector (tab-shaped male terminal) against the board to establish an electrical connection. Since the substrate that requires conductivity is integrally formed with the same metal, such as copper or brass, it is easy to manufacture, but the spring force of the elastic gripping arms is not necessarily sufficient. There was a problem.

Therefore, a two-part electrical connector has been proposed in which an elastic contact plate made of a highly elastic metal plate such as beryllium copper or phosphor bronze is assembled in addition to the electrical connector main body. According to this, by forming the electrical connector main body from a material with good conductivity and assembling an elastic contact plate made of a highly elastic metal plate to this, a reliable electrical connection can be obtained with sufficient spring force. ing.

(Problem to be solved by the invention) However, in the two-part electric connector,
Compared to electrical connectors in which the elastic clamping arms and the board are integrally formed, an extra assembly process is required for assembling the elastic contact plate to the main body, which increases the number of production processes. It was difficult to achieve accuracy, and there were also problems with reliability.

The present invention solves the problems of the prior art described above, and its purpose is to provide an electrical connector that can reduce the number of production steps and has reliability.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention includes an electrical contact portion having a substrate portion and elastic clamping arms provided on both sides of the substrate portion. In the electrical connector,
The electric contact portion is characterized in that it is formed from a composite plate of a highly conductive material forming the substrate portion and a spring material forming the elastic clamping arm.

(Function) The elastic holding arm made of a spring material brings the mating electrical connector into contact with a high contact load, and electricity passes through a portion made of a highly conductive material, making it possible to reduce electrical loss.

(Embodiment) FIG. 1 shows an embodiment of an electrical connector according to the present invention. The electrical connector E includes an electrical contact 1 and a wire connection 2 extending from the electrical contact 1.

The electrical contact part 1 consists of a base plate part 3 and elastic clamping arms 4 formed on both sides of the base plate part 3. This electrical contact part 1 has a mating electrical connector (not shown).
The contact piece is adapted to be inserted in the normal manner.

It should be noted that in the present invention, the substrate portion 3 is made from a highly conductive material 5 and the elastic clamping arms 4 are made from a spring material 6 (see FIG. 2). In this case, first, as shown in FIG. 2, a plate of high conductivity material 5 and plates of spring material 6 are joined to both sides of this plate. Then,
The plate of the spring material 6 is bent appropriately to form an electrical connector E as shown in FIG.

When the contact piece of the mating electrical connector is inserted into the electric contact part 1, this contact piece is held by the elastic gripping arm 4 of the spring member 6.
The high conductivity material 5 is pressed so as to come into pressure contact with the substrate portion 3, thereby obtaining reliable electrical contact.

[Effects of the Invention] According to the present invention, since the electrical connector is made of a highly conductive material and a spring material bonded to this material, the assembly process can be omitted, and the need for difficult technology in the assembly process can be omitted. disappears. Therefore, the electrical connector can be easily manufactured. Further, reliable electrical contact can be obtained by the elastic clamping arms made of spring material and the substrate part made of highly conductive material, and there is an advantage that a highly reliable electrical connector can be obtained.
