Electric connector of shielding cable, electric connector body and its manufacture

Abstract

This invention can obtain a stable impedance characteristic by improving reliability of connection of a grounding terminal and an external conductor, to attain improvement in manufacturing and equalization of the impedance characteristic between products by entirely eliminating soldering process, to make thinning available, and to prevent that the grounding terminal and the external conductor cause poor connection by making secondary mold. It is the electric connector 100 used for connection of shield cables 200, which have signal wires 210 and grounding wires 220. The first housing 120 is primarily molded to the external conductor 110, and a support projection 113, which contacts the grounding terminal 140 by projecting to the inner side of the external conductor 110, is formed. At the position, which faces the support projection 113 through the grounding terminal 140 in the second housing 160 which is secondarily molded, a through hole 161, which is made of a core pin 341 that has carried out pressing of the grounding terminal 140 by projecting into the inner direction from a mold 310, is provided.

Description

technical field [0001] The present invention belongs to the technical field of electrical connectors that are used to connect shielded cables with signal wires and ground wires, and can transmit signals at high speed according to applications. The present invention relates to an electrical connector provided with a conductive plate-shaped outer conductor whose ground terminal is grounded. The reliability of the connection to the outer conductor of the ground terminal is improved, and the manufacturability of the electrical connector is improved. Background technique [0002] It is known that an electrical connector for a shielded cable has: a conductive tubular outer conductor, an insulating housing accommodated inside the outer conductor, and a signal terminal and a ground terminal accommodated inside the housing; The signal terminal is connected to the signal line of the shielded cable, and the ground terminal is connected to the ground line of the shielded cable (for ex...

AI Technical Summary

Problems solved by technology

However, in this case, the welding work is added, and the work of connecting the wires becomes complicated.

In addition, it is difficult to manage the amount of solder to a certain extent, so there may be a problem of deviation in impedance characteristics between products.

This problem is also caused when the shielded cable and the terminal are connected by soldering
