Card edge connector

Abstract

The invention discloses a card edge connector, which integrates the functions of an inner buckle and an outer buckle, can reduce the mold cost and the assembly cost, and enhances the reliability of the buckles. The connector comprises a circuit board, and the circuit board is provided with an insulating body which can be in butt joint fit with a card edge. Slots extending to the shell are formed in the two ends of the insulating body, the slots penetrate through the insulating body, and the opening ends of the slots are adjacent to the inner wall of the shell; a buckle is inserted in the inserting groove and comprises an inserting section, a clamping hook is arranged at the end, close to the inserting groove, of the inserting section, and the clamping hook is inserted in the inserting groove. The buckle is provided with the two clamping hooks, and under the action of external force, the two clamping hooks can better prevent the buckle from being separated from the plastic main body; the buckle is provided with the resisting arm, the opening angle of the buckle is limited, and the buckle or the connector is prevented from being damaged when the opening angle of the buckle is too large.

Description

technical field [0001] The invention relates to the field of electrical connectors, in particular to a card edge connector, which includes a card edge connector with an integrated snap structure. Background technique [0002] The existing card edge connector is used for being disposed on the upper surface of a circuit board and for inserting an electronic card, so as to realize the electrical connection between the circuit board and the electronic card. The card edge connector is generally disposed on the circuit board, and can be inserted into one end of the memory card (or memory card), so as to realize the electrical connection between the memory card and the circuit board. [0003] The conventional buckle is composed of an inner buckle and an outer buckle, and two sets of molds need to be opened, and two sets of assembling are required, which increases the cost. Conventional clips only consist of a hook and a flat arm. When a hook is subjected to external force, it is e...

Problems solved by technology

[0003] The conventional buckle is composed of an inner buckle and an outer buckle. Two sets of molds need to be opened and two assemblies are required, which increases the cost

The conventional buckle is only composed of a hook and a flat arm. When a hook is subjected to external force, it is easy to cause the buckle to detach from the plastic body

Conventional buckles do not limit the opening angle of the buckle. The buckle can be opened at an excessive angle, which may easily cause damage to the buckle or the connector, or the buckle may touch other parts on the PCB.
