Description

connector assembly

The present invention relates to a connector assembly, in particular to a connector assembly with a heat sink.

Chinese Invention Patent Publication No. CN109283635B (corresponding to US Invention Patent Publication No. US10,295,767 B2) discloses a heat sink assembly for an optical transceiver. It is disclosed that the bottom of the heat sink of the heat sink assembly includes a front end slot that guides the movement of the heat sink relative to the cam structure and a rear end inclined slot. When the transceiver is partially inserted into the top bracket, there is a small gap between the thermal interface material of the heat sink and the transceiver. At this point, the cam structure is in contact with the slot, so the heat sink is positioned higher relative to the transceiver. After the transceiver is moved to the end of travel of the top bracket, the rear connector interface engages the connector electronics. At this point, the cam structure moves relative to the slot, so the heat sink is lowered relative to the transceiver. In the lowered position, the thermal interface material will contact the contact surface of the transceiver. The clamp attaches the heat sink and provides downward pressure on the heat sink to push the heat sink down and contact the transceiver. When the transceiver is to be withdrawn from the top bracket, the force of the spring pushing the cam structure forward is greater than the downward pressure of the clamp, so the heat sink is lifted away from the transceiver, which reduces the contact travel during insertion or removal of the transceiver Potential for damage to thermal interface material due to shear forces.

The above-mentioned prior art uses a cam structure to raise the heat sink to form a gap between the heat sink and the transceiver, so that the transceiver does not come into contact with the thermal interface material when it is partially inserted. However, how to raise the radiator in parallel by the cam structure lacks a specific structure that can be implemented, and raising the entire radiator in parallel requires two cam structures (the front cam structure and the rear cam structure) to achieve. On the other hand, , after the transceiver is moved to the end of travel of the top bracket, the simultaneous action of the two cam structures is also required to push the heat sink further down and make the transceiver contact the thermal interface material of the heat sink.

Accordingly, it is an object of the present invention to provide a connector assembly that improves at least one of the disadvantages of the prior art.
