Electric connector

Abstract

The invention discloses an electric connector, which is used for electrically connecting a first butt joint element to a second butt joint element, and comprises an insulating body, at least one accommodating groove and a plurality of connecting pieces, and is characterized in that the insulating body is provided with at least one accommodating groove; the at least one grounding terminal is fixedly arranged in the accommodating groove and is provided with a base part, a contact part extending from one end of the base part, a connecting part extending from the other end of the base part, and a fixed part extending from the side direction of the base part and fixedly held in the accommodating groove; a grounding piece is fixedly arranged in the containing groove and provided with a connecting beam, the connecting beam and the fixing part are located on the same side of the base part and contained in the containing groove, at least one clamping part extends from one side of the connecting beam, and the clamping part is clamped at the position, close to the fixing part, of the base part, so that the grounding terminal is fixed, and meanwhile the crosstalk problem is solved. A buffer space is formed between the position, close to the clamping part, of the connecting part and the insulating body, air is contained in the buffer space, and the insulating body abuts against and supports the position, close to the second butt joint element, of the connecting part so as to keep the flatness of the connecting part.

Description

【Technical field】 [0001] The invention relates to an electrical connector, especially a card edge electrical connector. 【Background technique】 [0002] The Chinese patent No. 202010884643.2 discloses a card edge electrical connector, which includes an insulating body, a row of second terminals, a row of first terminals and a grounding member. The insulating body includes opposite front and rear faces , and a card slot running through the front end surface, the first and second terminals include a connecting part, an elastic part extending from the connecting part to the card slot and pins, the elastic part has a protruding into the card slot The contact part, the connecting part of the first terminal extends out of the first fixing part, and the first fixing part is inserted into the insulating body from the rear end face; the connecting part has two opposite sides respectively facing adjacent terminals, a row of The first terminal includes a signal terminal and a ground te...

Problems solved by technology

[0003] (1) Although the elastic arms of the grounding member can be firmly pressed against the two opposite sides of the enlarged portion of the grounding terminal to improve the high-frequency performance of the card edge connector, the grounding terminal needs to be independent from the grounding terminal. The connecting part protrudes forward from the amplifying part, which increases signal loss and is not conducive to high-frequency performance
