Abstract

An electrical connector includes a bracket having a plurality of mating frames arranged side by side in a lateral direction and opening forward and plural transition modules inserted forward to be at least partially accommodated in the mating frame, wherein the bracket defines plural heat dissipation grooves each located between two adjacent frames and plural heat dissipation fins each located in a corresponding heat dissipation groove, the heat dissipation groove opening through in a front-rear direction.

First claim

What is claimed is:

1. An electrical connector for connecting plural cards to a printed circuit board, comprising:
a bracket having a plurality of mating frames arranged side by side in a lateral direction and opening forward for receiving the cards; and
a plurality of transition modules inserted forward to be at least partially accommodated in the mating frames for electrically connecting the card and the printed circuit board;
wherein the bracket defines a plurality of heat dissipation grooves each located between two adjacent frames and a plurality of heat dissipation fins each located in a corresponding heat dissipation groove, the heat dissipation groove opening through in a front-rear direction; and
wherein the bracket comprises a metallic housing and a plurality of insulative housings, the metallic housing comprises a main body extending laterally and a plurality of walls extending rearward from the main body, the plurality of insulative housings are arranged in the main body to collectively form the mating frames, and each transition module is located between two adjacent walls.

2. The electrical connector as claimed in claim 1 , wherein the heat dissipation grooves are disposed in the metallic housing, and the heat dissipation fins extend substantially parallel to the walls.

3. The electrical connector as claimed in claim 1 , wherein the transition module defines a first end arranged in the frame and a second end for connecting with the circuit board, and each transition module comprises a first wafer and a second wafer each having a plurality of terminals extending from the first end to the second end.

4. The electrical connector as claimed in claim 1 , wherein the insulative housing is located in the main body and extends rearward.

5. The electrical connector as claimed in claim 1 , wherein the transition module comprises a housing and a plurality of terminals located in the housing, the terminal comprises a matching portion for matching with the card, and the insulative housing defines slots on both sides of the matching portion.

6. The electrical connector as claimed in claim 1 , wherein the heat dissipation fins and side walls of the heat dissipation grooves are unitary, and a gap is defined between the heat dissipation fin and the two adjacent side walls.

7. The electrical connector as claimed in claim 1 , wherein a front end of the heat dissipation fin is substantially flush with a front surface of the bracket.

8. The electrical connector as claimed in claim 1 , wherein the bracket comprises a baffle wall upstanding in the heat dissipation groove, an outer periphery of the baffle wall is connected with an inner wall of the heat dissipation groove so that the baffle wall blocks the heat dissipation groove along the front-rear direction, and the heat dissipation fin is fixed in the heat dissipation groove by the baffle wall.

9. The electrical connector as claimed in claim 1 , wherein the bracket comprises two outermost holding portions staggered in the front-rear direction.

10. An electrical connector comprising:
a metallic housing defining a plurality of upright receiving slots along a lateral direction, each upright slot opening through along a front-rear direction with a mating face at a front side thereof, and a partition wall between every two adjacent upright slots; and
a plurality of transition assemblies received in the upright slots, respectively;
wherein the partition wall is divided into three parts along the lateral direction to form two heat dissipation sub-grooves at each partition wall.

11. The electrical connector as claimed in claim 10 , wherein a front part and a rear part of the heat dissipation sub-groove is separated by a baffle wall, the front part only opening forward while the rear part opening rearward and opening through along an upright direction.

12. An electrical connector comprising:
a housing having a main body defining a plurality of receiving slots along a lateral direction, a front partition wall between every two receiving slots, and a plurality of rear partition walls extending from a rear face of the main body, the receiving slot extending rearward between every two adjacent partition walls; and
a plurality of transition assemblies having conductive elements and being received in the receiving slots;
wherein the front partition wall defines a front heat dissipation groove opening forwards and a heat dissipation fin in the front heat dissipation groove, the rear partition wall includes three extending walls extending from the rear face of the main body, the three extending walls are separated from each other in the lateral direction.

13. The electrical connector as claimed in claim 12 , wherein the heat dissipation fin is aligned with a middle extending wall of the three extending walls.

14. The electrical connector as claimed in claim 13 , wherein the front heat dissipation groove is baffled rearwards.

15. An electrical connector for connecting plural cards to a printed circuit board, comprising:
a bracket having a plurality of mating frames arranged side by side in a lateral direction and opening forward for receiving the cards; and
a plurality of transition modules inserted forward to be at least partially accommodated in the mating frames for electrically connecting the card and the printed circuit board;
wherein the bracket defines a plurality of heat dissipation grooves each located between two adjacent frames and a plurality of heat dissipation fins each located in a corresponding heat dissipation groove, the heat dissipation groove opening through in a front-rear direction; and
wherein the bracket comprises a baffle wall upstanding in the heat dissipation groove, an outer periphery of the baffle wall is connected with an inner wall of the heat dissipation groove so that the baffle wall blocks the heat dissipation groove along the front-rear direction, and the heat dissipation fin is fixed in the heat dissipation groove by the baffle wall.
