The invention provides a card edge connector. The card edge connector comprises a longitudinal insulation body, a plurality of conductive terminals fixed on the insulation body and metal fastening members which are fixed at two sides of the insulation body, wherein each of the metal fastening members comprises a fixing portion, a base portion, an elastic arm and a horizontal arm, the fixing portion is fixed on the insulation body, the base portion extends from the fixing portion, the elastic arm inclines and extends forwards from the front end of the base portion, the horizontal arm is bent from the lower end of the base portion and extends forwards horizontally, and the elastic arm is provided with a pressing body which is used for pressing a sub-circuit board. Each of the metal fastening members is also provided with a limiting body which is bent and extends from the horizontal arm. The limiting body comprises a first limiting portion and a second limiting portion, the first limiting portion is bent and extends upwards from one side of the horizontal arm and the second limiting portion is bent and extends from the top of the first limiting portion to the elastic arm. The second limiting portion is provided with a limiting groove which extends along a longitudinal direction of the insulation body. The elastic arm is provided with a retaining piece which is bent toward the first limiting portion. The retaining piece is provided with a sliding block which protrudes upwards into the limiting groove. The card edge connector is stable in whole mechanism.
Description
technical field [0001] The invention relates to a card edge connector, in particular to a card edge connector with a stable structure and a metal buckle thereof. Background technique [0002] The card edge connector is used to be welded on a mother circuit board and plugged into a daughter circuit board so as to electrically connect the mother circuit board and the daughter circuit board. The two sides of the sub-circuit board are usually respectively provided with notches for buckling with the card edge connectors. The card edge connector generally includes an insulating body, a plurality of conductive terminals fixed on the insulating body, and two metal fasteners fixed on both sides of the insulating body. The insulating body is provided with a central slot for inserting the sub-circuit board. Each conductive terminal is provided with a contact portion extending into the central slot for connecting with the daughter circuit board, and a soldering leg extending out of th...
