Card edge connector having heat-dissipating mechanism

1. A card edge connector mountable on a mother circuit board, the card edge connector comprising:

an elongated insulative housing comprising a bottom wall and a pair of parallel sidewalls each defining a plurality of passages therein, the bottom wall and the sidewalls jointly enclosing a central slot to receive a daughter circuit card therein; and

a plurality of conductive terminals residing in corresponding passages, respectively, the conductive terminals each comprising a contacting section projecting to the central slot to electrically and mechanically mate with the daughter circuit board and a mounting section to be mounted to the mother circuit board, and

wherein the bottom wall of the housing defines a plurality of airways in communication with the central slot; wherein the airways are aligned with a pair of opposing conductive terminals; and

wherein the side walls define a plurality of passageways along a lengthwise direction, and the terminals are respectively disposed in the corresponding passageways, under a condition that the airways does not laterally communicate with the corresponding passageways.

2. The card edge connector of claim 1 , wherein the passage comprises an opening terminating at an inner surface of the sidewall.

3. The card edge connector of claim 1 , wherein the passage comprises an upper channel and a lower channel terminating at an outer surface of the sidewall.

4. The card edge connector of claim 1 , wherein the housing comprises a pair of towers at two ends thereof, a plurality of board locks are coupled to the towers to securely mount the housing on the mother circuit board.

5. The card edge connector of claim 4 , wherein the tower comprises a pair of platforms and an over bridge linking the platforms, the platforms and the over bridge jointly define a receiving chamber.

6. The card edge connector of claim 5 , wherein a pair of latch/eject members are pivotally assembled in the receiving chambers, respectively, to lock the daughter circuit board in position.

7. An electrical connector comprising:

an elongated insulative housing having a central slot cooperatively enclosed by a bottom wall and a pair of sidewalls thereof, the bottom wall defining a plurality of airways in communication with the central slot; and

a plurality of conductive terminals spaced along the central slot for mechanical and electrical engagement with an electronic component coupled thereto:

wherein the airways vent heat generated in the housing out through a bottom surface of the bottom wall of the housing;

wherein the airways are aligned with a pair of opposing conductive terminals; and

wherein the side walls define a plurality of passageways along a lengthwise direction and in communication with a central slot, and the terminals are respectively disposed in the corresponding passageways, under a condition that the airways does not laterally communicate with the corresponding passageways.

8. The electrical connector of claim 7 , wherein the passages each comprise an opening terminating at an inner surface of the sidewall.

9. The electrical connector of claim 7 , wherein the passages each comprise at least one channel immediately connected to outer circumstance.

10. The electrical connector of claim 7 , wherein the housing comprise a pair of towers seated at two ends thereof, each tower defines a receiving chamber therein.

11. The electrical connector of claim 10 , wherein pair of latch/eject members is movably coupled to the receiving chambers, respectively, for locking the electronic component in position.
