Card edge connector

Abstract

The invention discloses a card edge connector comprising a longitudinal insulation body and a plurality of conductive terminals fixed on the insulation body, wherein the insulation body comprises two side walls extending along the longitudinal direction, end walls connecting tail ends of the two side walls, and a central slot encircled by the two side walls and the end walls; the plurality of conductive terminals are respectively installed on the two side walls; each terminal is provided with a base part fixed on the corresponding side wall, an installation part extending out of the insulation body from one end of the base part, two extending parts extending from the other end of the base part, and two contact parts respectively extending to the central slot from the two extending parts; the base part, the extending parts, the contact parts and the installation part of each conductive terminal are positioned on the same plane, the two extending parts comprise a first extending part close to the central slot and a second extending part far away from the central slot, the first extending part is bent for many times to reduce positive pressure of the conductive terminal.

Description

[0001] 【Technical field】 [0002] The invention relates to a card edge connector, in particular to a card edge connector with double-point contact. [0003] 【Background technique】 [0004] US Patent No. 7,637,783B discloses a card edge connector, which includes an insulating body with a central slot and two rows of conductive terminals mounted on both sides of the central slot. Each conductive terminal includes a mounting portion extending leftward, a base portion extending forward from the mounting portion and then bent rightward, and two separate extension portions extending backward from the base portion and extending upward. The two extension parts are respectively bent downward and rightward to form two contact parts extending downward and upward respectively, and the two contact parts are used for double-point contact with the memory module. A contact portion of the conductive terminal extends upwards, which is opposite to the insertion direction of the memory module, wh...

AI Technical Summary

Problems solved by technology

Each conductive terminal is inserted and installed on both sides of the central slot from top to bottom. Each conductive terminal includes a base fixed to the insulating body, two extensions extending upwards from the base, and two extensions from the two extensions. The arc-shaped protruding parts protruding inward, because the thickness of the protruding parts in the horizontal direction is extremely large, they have no elasticity. When the circuit board module is inserted into the central slot, it can only rely on the extension part to deform. The extension part is straight, so the positive pressure between the conductive terminal and the circuit board module is extremely high, which easily causes the extension part of the conductive terminal to be plastically deformed, making it unusable
