Problems solved by technology
However, the metal grounding piece is easy to increase the cost, and may affect the interference combination between the terminal module and the insulating shell. On the other hand, the conductive terminal has a contact portion exposed to the outside of the insulating shell. The terminal contact part is prone to short circuit problems caused by displacement

Embodiment Construction
[0018] see Figure 1 to Figure 9 As shown, the present invention discloses a card edge connector 100 , which is a PCI Express connector and includes an insulating body 1 , a terminal module 2 and a grounding strip 3 accommodated in the insulating body 1 . The insulating body 1 includes two elongated sidewalls 11 and a slot 10 between the sidewalls 11 . The terminal module 2 includes an insulating block 4 and two rows of terminals 5 fixed on the insulating block 4 . Each row of terminals 5 includes several ground terminals 51 and several signal terminals 52 . Two longitudinal sides of the insulating block 4 are recessed inwardly with a long groove 41 and a groove 42 formed by further inwardly recessing from the bottom of the long groove 41 to expose the ground terminal 51 . The ground strip 3 is made of conductive plastic, which is accommodated in the long groove 41 and has a convex portion 32 extending inward and entering the groove 42. The convex portion 32 abuts against th...

A card edge connector comprises an insulation body, a terminal module and a grounding strip, the terminal module and the grounding strip are accommodated in the insulation body, the insulation body comprises two lengthwise side walls and a slot located between the side walls, the terminal module comprises an insulation block and two rows of terminals fixed on the insulation block, and each row of terminals comprises a plurality of grounding terminals; the two lengthwise side faces of the insulating block are provided with long grooves and grooves which are formed by further sinking inwards from the bottom faces of the long grooves and enable the grounding terminals to be exposed, and the grounding strips are made of conductive plastic, contained in the long grooves and provided with protruding parts which extend inwards to enter the grooves. The protruding part abuts against the grounding terminal to achieve electrical connection, or a gap is reserved between the protruding part and the grounding terminal to achieve electrical connection through electromagnetic induction. According to the arrangement, the high-frequency performance of the card edge connector is improved by matching the grounding strip made of the conductive plastic with the grounding terminal in the terminal module.
Description
