Description

Connector assembly

Technical Field

The present invention relates to a connector assembly, and more particularly, to a connector assembly having a heat sink.

Background

U.S. patent publication No. US7,625,223 discloses a socket assembly including a lead frame, a heat sink, and a conductive gasket. The guide frame includes a top wall and defines an interior chamber configured to receive a mating connector. The top wall defines an opening communicating with the interior chamber. The heat sink is held in the internal chamber such that when the mating connector is inserted into the internal chamber, the upper portion of the heat sink passes through the opening and the lower portion engages with the mating connector. The conductive gasket is held between the guide frame and the heat sink. The heat sink includes a coupling portion that provides a thermal path for the mating connector when the mating connector is inserted into the interior chamber. The conductive gasket is configured to be compressed between the lead frame and the heat sink such that the conductive gasket provides a conductive path between the heat sink and the lead frame. However, the heat sink disclosed in the prior art is a metal heat sink having heat dissipating fins, and the principle thereof is that the heat is taken out by the air flow flowing between the heat dissipating fins, and the heat dissipating efficiency is slightly insufficient in the connector assembly with higher transmission speed and larger heat generation amount.

Chinese patent publication No. CN110139534A (corresponding to US patent publication No. US2019/0246523a1) discloses a cooling device, which includes a manifold and a plurality of pedestals. The manifold includes a housing enclosing an interior cavity for receiving a cooling liquid and circulating a flow of the cooling liquid. Each base is separately and flexibly coupled to the housing of the manifold by a bellows to seal and ring. Each pedestal is configured to extend outwardly from a bottom surface of a housing of the manifold when fluid pressure is present within the internal cavity. However, this prior art bellows only provides a flexible connection between the base and the manifold, requiring that the base have sufficient strength to extend outwardly from the bottom surface of the housing of the manifold in the presence of fluid pressure in the internal cavity of the manifold. Firstly, the corrugated pipe is used as a connecting sealing piece between the base and the manifold, so that the structure is complex and the manufacturing difficulty is high; secondly, because the base can extend outwards only through fluid pressure, when the fluid pressure is insufficient or the pressure is unstable, the outward protruding amount of the base relative to the manifold is easy to be insufficient, so that the pressure of the base contacting the electrical module is insufficient or even the base cannot contact the electrical module, and further the heat dissipation efficiency is reduced.
