Card edge connector

Abstract

The invention provides a card edge connector, which comprises a strip insulating body seat provided with a plurality of jacks, a group of connecting terminals arranged in parallel and two cantilever supporting frames arranged at the two ends of the insulating body seat, wherein the connecting terminals are inserted into the jacks of the insulating body seat to form a group of spliced electrodes electrically connected with a circuit board; and each of the cantilever supporting frames is provided with an auxiliary supporting frame which can be connected with the circuit board, and the auxiliary supporting frame is sleeved and hinged with the corresponding cantilever supporting frame mutually. Through the micro-clearance fit between the auxiliary supporting frames and the cantilever supporting frames, the card edge connector can solve the technical problem that hemlines of the auxiliary supporting frames and welded pins of the connecting terminals are in the same plane, effectively ensures that the welded pins on the connecting terminals and circuit board connecting points are not swayed under the influence of an external force for inserting and extracting an electronic card, improves the connecting stability and the use reliability of the connector, and correspondingly improves the yield and the service life of the connector.

Description

technical field [0001] The invention relates to a connector structure in electronic products, in particular to a card edge connector used for fixing flat or strip-shaped electronic cards. Background technique [0002] With the development of electronic technology, various flat or strip electronic cards have been widely used in various electronic equipment (such as electronic communication equipment, computers, etc.). The connection terminals of the circuit board are electrically connected to the circuit board through soldering feet, and the connector needs to fix the electronic card at the same time. At present, the existing connector mainly includes: a strip-shaped insulating body seat containing multiple jacks, a group of connecting terminals arranged in parallel, and two cantilever arms arranged at both ends of the insulating body seat for fixing the connector. Support frame; the upper end of each connecting terminal has a contact portion, which can be placed in the sock...
