Abstract
A card edge connector for electrically connecting a circuit card to a mother board includes an insulative housing having an elongated base and a pair of supporting arms extending perpendicularly from opposite lateral ends of the base, a number of conductive terminals, and a pair of latch members disposed at free ends of the pair of supporting arms. Each latch member has a latch tab for bearing against an upper surface of the circuit card and reliably locking the circuit card. The base defines an elongated slot along a longitudinal direction thereof and a number of passageways disposed by two sides of the slot for receiving the conductive terminals therein. Each terminal extends into the slot for engagement with the inserted circuit card.
Claims6
A card edge connector assembly for electrically connecting a circuit card to a mother board, comprising:
- an insulative housing having an elongated base and a pair of supporting arms extending perpendicularly from opposite lateral ends of the base, said base defining an elongated slot along a longitudinal direction thereof and a plurality of passageways beside the slot;
- a plurality of conductive terminals received in corresponding passageways and extending into the slot for engagement with the circuit card inserted into the connector;
- and
- a pair of latches disposed at free ends of the pair of supporting arms, each latch having a latch tab for locking the circuit card, the latch tab comprising a blocking portion for bearing against an upper surface of the circuit card and a touching portion for engaging a side surface of the circuit card;
- wherein
- said latches are plastic latches molded integrally with the insulative housing:
- wherein
- each of said latches has a tapered plate extending upwardly from a top surface of the supporting arm and a curved portion bent inwardly and then downwardly from the top of the tapered plate;
- wherein
- the blocking portion of said latch tab extends horizontally from the bottom of the curved portion towards the tapered plate, and the touching portion extends downwardly from the blocking portion.
An electrical connector assembly comprising:
- an electrical connector comprising:
- an insulative housing having an elongated base and a pair of supporting arms integrally molded with the base and extending perpendicularly from opposite lateral ends of the base, said base defining an elongated slot along a longitudinal direction thereof and a plurality of passageways disposed beside of the slot, each supporting arm having a latch extending integrally and upwardly therefrom, each latch having a latch tab for locking a circuit card;
- a plurality of conductive terminals received in corresponding passageways and extending into the slot;
- and
- a pair of engaging members each comprising a soldering plate adapted to be soldered on a mother board, a mating plate engaging in said supporting arm, and a slanting portion connecting the soldering plate and the mating plate;
- and
- a circuit card received in the slot and having two rows of contact pads on upper and lower surfaces of an edge thereof for mating with the conductive terminals, the circuit card further defining a pair of cutouts in opposite sides thereof for engaging with the pair of latches;
- wherein the latches of the electrical connector project beyond the upper surface of the circuit card, and are subject to squeezing force to disengage from the circuit board when the circuit card is to be withdrawn from the electrical connector;
- wherein
- said latch has a tapered plate extending upwardly. from a top surface of said supporting arm for providing perpendicular alignment of the circuit card, wherein
- said latch has a curved portion bent inwardly and then downwardly from the top of the tapered plate.
