Abstract

The utility model aims in that provides a card edge connector used to connect an enlarged card to the circuit board; the utility model comprises a longwise insulation body which is provide with a center slot, and a plurality of conducting terminals. The utility model is characterized in that the card-edge connector comprises a metal shell which envelops the insulation body as the shielding. The metal shell is used to prevent the electromagnetic interference due to the installation of the metal shell, thereby realizing the normal operation of the connector., the card-edge connector can work normally.

Description

Bayonet connector

[technical field]

The utility model relates to a kind of bayonet connector.

[background technology]

At present, industry is in order to connect the bayonet connector of expansion board and circuit board, be typically provided with a plastics pedestal and an ear clip device, the plastics pedestal is provided with plurality of conductive terminals, its both sides are provided with turriform portion, be provided with the receiving space of accommodating ear clip device in the turriform portion, the receiving space two side is provided with pivoted hole, ear clip device is articulated in the pivoted hole, this ear clip device can be with firm being held in the bayonet connector of expansion board, prevent to produce signal interruption, also be provided with trip mechanism on the ear clip device simultaneously, can expansion board be withdrawed from the bayonet connector by the rotation of earclip because of vibrations break away from.But along with the development of electronic equipment, the electromagnetic interference that is produced in running is also more and more serious, obviously can have a strong impact on the normal operation of this kind bayonet connector.

Therefore, be necessary to design a kind of novel bayonet connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of bayonet connector, can guarantee its normal operation.

In order to reach above-mentioned creation purpose, the utility model bayonet connector, in order to expansion board is connected on the circuit board, comprise that one is provided with the lengthwise type insulating body and the plurality of conductive terminals of central slot, described bayonet connector also comprises the metal shell with bridging effect of a coated insulation body.

Compared with prior art, the utility model bayonet connector owing to the setting of metal shell, can cover the influence of electromagnetic interference, realizes its normal operation.
