An edge connector is a type of electrical connector for use with PC boards. They consist of a plastic "box" open on one side, with pins on either side of the longer edges, sprung to push into the middle of the open center. PC boards are then constructed with traces leading to the edge of the board, which are then slid into the edge connector. The edge connector is a money-saving device because it only requires a single connector, and they also tend to be fairly robust. For a time they were used in the vast majority of connectors found in computers, but modern computers have demanded many more pins than can easily be accommodated on the edge of a reasonable size board, and today more traditional male/female connectors are more common.
The plastic member defines a locking protrusion and a restriction protrusion respectively abutting against the upper surface and received within the notch of the module, while the metal member defines a pair of grounding tangs respectively engaged with the corresponding grounding pads on two opposite surfaces of the module.
1 and 3, a card edgeconnector 1 of the present invention is adapted to be mounted to a circuit board (not shown) for insertion of an electronic card (not shown) so as to enable the circuit board to electrically connect with the electronic card by means of the card connector 1.
The card connector 1 mainly includes an insulative housing 2 having a plurality of terminals 3 therein, and a pair of reinforcement member 4 respectively disposed and detachably secured on two opposite ends of the insulative housing 2.
An electrical connector as set forth in claim 3 characterized in that each of the arcuate supporting surfaces has a radius of curvature which is substantially equal to the radius of curvature of the associated bight portion, each bight portion being against its associated supporting surface when the first arms are flexed.
An electrical connector as set forth in claim 13 characterized in that the extensions have inclined surfaces against which the circuit board is positioned when the circuit board is in its functional position, the angle of inclination being the second acute angle.
An electrical connector as set forth in claim 16 characterized in that the ears are inclined at the second acute angle whereby the edge portions of the board are clamped between the ears and the inclined surfaces of the extensions when the board is in its functional position.
