Abstract

The present invention relates to a pair of electrical connectors using resin solder unilaterally. The first electrical connector (100) has: a first set (110) formed by synthetic resin; and a first terminal (120) with a contact part (121) ) and the connecting portion (122) are exposed on the surface of the first set (110) and integrally formed on the first set (110), and are formed by lead-free ultra-high conductive plastic composed of conductive resin composition. And the second electrical connector (200) has: the second set (210), which is formed by insulating material; and the second terminal (220), which is formed by a conductive material that is more elastic than lead free ultra-high conductive plastic and The second set (210) has a contact portion (221) contacting the contact portion (121) of the first terminal (120) and a connection portion (222) exposed on the surface of the second set (210). The object of the present invention is to provide an electrical connector which can flow a larger current than a terminal formed according to MID, can be formed into various shapes according to the part to be used, and does not require soldering work.

Description

【Technical field】 [0001] The present invention belongs to the technical field of electrical connectors. The electrical connectors are provided with terminals using lead-free ultra-high-conductivity plastics made of conductive resin compositions, and counterpart electrical connectors paired with the electrical connectors. 【Background technique】 [0002] In general, an electrical connector includes a housing formed of an insulating material, and electrical contacts assembled in the housing. On the other hand, there is known an electrical connector manufactured by MID (Molded Interconnection Device) technology (for example, refer to Registered Utility Model Patent No. 2597015). This electrical connector includes a sleeve formed of synthetic resin, and terminals formed by plating the surface of the sleeve. The electrical connector and the sleeve do not need to manufacture additional electrical contacts, so the manufacturing cost of the electrical connector can be reduced. [0...
