Abstract

An electrical connector assembly includes: a metal shell including a top wall, a bottom wall, a pair of parallel spaced side walls connecting the top and bottom walls, a receiving space, and a front opening communicating with the receiving space; a connector received in the receiving space of the metal shell; and a heat sink disposed in the rear side of the metal shell, wherein the metal shell includes a rear opening communicating with the receiving space, and the heat sink covers the rear opening.

First claim

What is claimed is:

1. An electrical connector assembly comprising:
a metal shell including a top wall, a bottom wall, a pair of parallel spaced side walls connecting the top and bottom walls, a receiving space, and a front opening communicating with the receiving space;
a connector received in the receiving space of the metal shell; and
a heat sink disposed in a rear side of the metal shell,
wherein the metal shell includes a rear opening communicating with the receiving space, and the heat sink covers the rear opening;
further includes a heat conducting member assembled with the heat sink, the heat conducting member extends forward beyond a front end of the connector; wherein
the metal shell includes an intermediate member dividing the receiving space into an upper receiving space and a lower receiving space spaced apart from the upper receiving space in a vertical direction; wherein
the intermediate member includes a lower through hole communicating with the lower receiving space, the metal shell includes a heat dissipation block received in the intermediate member to extend through the lower through hole into the lower receiving space for thermal conduction with a plug module received in the lower receiving space, and the heat conducting member is thermally conducted with the heat dissipation block; wherein
the top wall includes an upper through hole connecting with the upper receiving space, the metal shell includes an upper heat sink disposed on the top wall, the upper heat sink extends through the upper through hole into the upper receiving space and is thermally conducted with a plug module received in the upper receiving space.

2. The electrical connector assembly as claimed in claim 1 , wherein the heat conducting member directly connects with the heat dissipation block.

3. The electrical connector assembly as claimed in claim 1 , wherein the heat conducting member includes a pair and the pair of heat conducting members are disposed on the both sides of the heat dissipation block.

4. The electrical connector assembly as claimed in claim 1 , wherein the heat sink includes a plurality of heat dissipation channels extending in a front-to-back direction perpendicular to the vertical direction, and the upper heat sink includes a plurality of heat dissipation channels extending in the front-to-back direction.

5. The electrical connector assembly as claimed in claim 1 , wherein the metal shell includes a buckle member transversely spanning the upper heat sink and fitting with the side wall to fix the upper heat sink to the metal shell.

6. The electrical connector assembly as claimed in claim 1 , wherein the heat sink includes a mounting hole, and the heat conducting member is mounted in the mounting hole.

7. An electrical connector assembly comprising:
a metal shell including a top wall, a bottom wall, a pair of parallel spaced side walls connecting the top and bottom walls, a receiving space formed by the top wall, the bottom wall and the side walls with a front opening forwardly communicating the receiving space with an exterior, the top wall forming a top opening and the bottom wall forming a bottom opening, said shell forming no rear wall but a rear opening rearwardly communicating with the exterior;
an upper heat sink intimately positioned upon the top wall and covering the top opening in a vertical direction
a connector received in a rear portion of the receiving space of the metal shell and covering the bottom opening in the vertical direction; and
a rear heat sink disposed intimately behind the shell and covering the rear opening to forwardly communicate with the receiving space in a front-to-back direction perpendicular to the vertical direction; wherein
the rear heat sink is supported by a pair of heat conductive members which extend through the connector along the front-to-back direction; wherein
the metal shell includes an intermediate member dividing the receiving space into an upper receiving space and a lower receiving space spaced apart from the upper receiving space in said vertical direction; wherein
the intermediate member includes a lower through hole communicating with the lower receiving space, the metal shell includes a heat dissipation block received in the intermediate member to extend through the lower through hole into the lower receiving space for thermal conduction with a plug module received in the lower receiving space, and the heat conducting member is thermally conducted with the heat dissipation block; wherein
said upper heat sink extends through the top opening into the upper receiving space and is thermally conducted with a plug module received in the upper receiving space.

8. The electrical connector assembly as claimed in claim 7 , wherein rear heat sink includes a plurality of fins unified by at least one transverse bar through which the pair of heat conductive members extend along the front-to-back direction.

9. The electrical connector assembly as claimed in claim 8 , wherein the fins form corresponding heat dissipation channels along the front-to-back direction, the heat dissipation channel at a center is deepest while those at two sides are shallowest for complying with extension of the pair of corresponding heat conductive members.

10. The electrical connector assembly as claimed in claim 8 , wherein a rear edge of each of said side walls forwardly abuts against the transverse bar.

11. The electrical connector assembly as claimed in claim 10 , wherein the rear edge of each of said side walls forms a protrusion forwardly abutting the transverse bar.
