Edge connector

Abstract

The invention provides an edge connector. The edge connector comprises a lengthwise insulation body, a plurality of conducting terminals which are fixedly arranged on the insulation body and a pair of metal holding pieces which are fixedly arranged at two opposite sides of the insulation body, wherein the insulation body is provided with a center slot which is provided with an forward opening and is used for plugging a sub circuit board; the conducting terminals are provided with contact parts stretching into the center slot in a protruding way; and each metal holding piece is provided with a fixed holding arm which is fixedly held on the insulation body, an elastic arm which forwards and obliquely stretches from the fixed holding arm and a limit arm which is positioned at one side of the elastic arm, and the elastic arm is provided with a pressing-against body which downwards and obliquely stretches from the top part, a limit groove which penetrates through the elastic arm along a lengthwise direction of the insulation body and a first separation blade which is used for covering the lower position of the limit groove. The limit arm is provided with a limit piece stretching in the limit groove in a bending way, and thus the elastic arm is prevented from moving upwards.

Description

technical field [0001] The invention relates to a card edge connector, in particular to a card edge connector with a metal buckle. Background technique [0002] For the prior art related to the present invention, please refer to the Chinese Invention Patent Publication No. CN 102347536 A published on February 8, 2012, which discloses a card edge connector for soldering to a mother circuit board and provide a sub-circuit board for plugging in, so as to electrically connect the mother circuit board and the sub-circuit board. The two sides of the sub-circuit board are respectively provided with notches for locking with the card edge connector. The card edge connector includes an insulating body, several conductive terminals fixed on the insulating body, and two ear buckle mechanisms fixed on both sides of the insulating body. The insulating body is provided with a central slot for inserting the sub-circuit board. The ear button mechanism includes a first ear button and a sec...

Problems solved by technology

[0003] Because the connecting arm and the limiting part have no restrictions along the thickness direction of the insulating body; thus, when the sub-circuit board inserted into the central slot is misoperated and directly withdraws upward, the guide card on the limiting part is held body against the upper surface of the sub-circuit board, so that the misoperation of directly withdrawing from the sub-circuit board upwards will cause the limit part to drive the connecting arm to twist and deform upwards, thereby affecting the connection stability between the sub-circuit board and the card edge connector
