Card Edge Electrical Connector

Abstract

The invention relates to a card edge electrical connector used for electrically inserting an expansion card. The card edge electrical connector comprises a base body and stop pins. One end of the base body is equipped with at least one protruding shaft. The outer profile of the protruding shaft is in a polygonal shape. Each stop pin is equipped with a shaft hole, and the shaft holes are in a polygonal shape matched with the protruding shafts. The stop pins are pivoted to the protruding shafts via the shaft holes respectively, so that the corners of each shaft hole and the corners of the corresponding protruding shaft form a polygonal positioning structure. Each stop pin can be rotated around the base body with the corresponding protruding shaft as the rotation axis, and one corner of each protruding shaft is abutted against one corner of the corresponding shaft hole, so that the stop pins may buckle or loosen the expansion card. Thus, force on the buckling points is dispersed to decrease wear rate. Therefore, the stop pins may maintain good holding force and buckling force for a long time, and the service life of the card edge electrical connector is prolonged.

Description

[0001] 【Technical field】 [0002] The invention relates to an electrical connector, in particular to a card edge electrical connector with a stop pin. [0003] 【Background technique】 [0004] Many electronic devices use expansion cards to improve the performance of electronic devices. For example, the increase of memory cards can make the computer system quickly and smoothly handle huge application calculations, and these expansion cards are quite small. In order to make these expansion cards and circuits As a result, different types of electrical connectors have been developed, among which the card-edge electrical connector that uses stop pins to fix expansion cards is the most common one. [0005] Generally speaking, stopper pins are provided on the ends of both sides of the card edge type electrical connector for loading memory cards, and these stopper pins can help to fix the memory card in the slot of the card edge type electrical connector, It can also be used to eject t...

AI Technical Summary

Problems solved by technology

[0009] In view of the above problems, the present invention provides a card edge electrical connector, so as to solve the problem that the stop pin of the conventional card edge electrical connector adopts the design of engaging the tenon and the card slot, which causes stress concentration during use. At the buckle point, the structure is easy to wear and cause fatigue damage, resulting in the reduction of the fixing force of the stop pin and the loosening of the memory card
