Abstract

The invention discloses an electric connector, which comprises a body, a signal terminal and at least one grounding terminal, wherein the body is provided with a butting surface and sinks downward from the butting surface to form an inserting slot used for accommodating a butting element, the inserting slot is provided with a slot bottom surface, the body is provided with two side walls respectively located at two sides of the inserting slot, at least one side wall includes a first portion formed by insulation plastic and a second portion arranged on the first portion, the first portion is provided with a signal terminal hole, the second portion is made of conductive plastic and provided with a plurality of grounding terminal holes, the signal terminal hole and the grounding terminal holesare communicated with the inserting slot, and the grounding terminal holes at least partially exceed the slot bottom surface upward; the signal terminal is correspondingly accommodated in the signalterminal hole; the at least one grounding terminal is correspondingly accommodated in the at least one grounding terminal hole and connected with the second portion in a conductive manner; and both the signal terminal and the grounding terminal are provided with a contact portion, the contact portion protrudes into the inserting slot so as to be electrically connected with the butting element. Theelectrical length of the grounding terminal is changed through the second portion made of the conductive plastic to improve the high frequency performance.

Description

[0001] 【Technical field】 [0002] The invention relates to an electrical connector, especially an electrical connector suitable for transmitting high-frequency signals. [0003] 【Background technique】 [0004] With the development of technology and the upgrading of electronic components, the requirements for the frequency of signals transmitted by electrical connectors are getting higher and higher. For example, the PCI-E 5.0 specification under formulation expects the frequency of signals transmitted by electrical connectors to reach 32G, while transmission of high frequency One of the problems caused by the signal is that it is easy to generate high-frequency resonance, which is not conducive to signal transmission. In order to solve the above problems, the industry has tried to use conductive plastic to connect all the grounding terminals in the electrical connector, so as to improve the high-frequency performance of the electrical connector. The so-called conductive plasti...
