Technical Field

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

Background

In the prior art, a high-speed optoelectronic connector generally includes a housing (or referred to as an iron cage), a heat sink mounted on a top wall of the housing, and a spring clip holding the heat sink to the housing.

In the prior art, for a case having a plurality of insertion chambers arranged side by side, a heat sink is mounted on the top wall of each insertion chamber, and the heat sink is held on the case by an elastic clip. In this application, the spring clip includes a pair of longitudinal beams extending in the longitudinal direction of the housing and a pair of transverse beams connected to both ends of the pair of longitudinal beams, respectively. A plurality of elastic pressing fingers are formed on each of the pair of transverse beams. When the elastic clip is fixed to the top wall of the housing, the elastic pressing fingers on the pair of transverse beams press against both ends in the longitudinal direction of the heat sink, respectively, thereby holding the heat sink to the housing.

In the prior art, in order to avoid the elastic pressing finger of the elastic clip, a large blank area for the elastic pressing finger to press and without arranging the heat dissipation column or the heat dissipation fins needs to be reserved on the heat sink, which reduces the heat dissipation area of the connector and the service life of the product. In addition, the length of the heat sink is also limited by the elastic clip, and the heat sink cannot meet the requirements of different heat dissipation performances.

In order to increase the effective heat dissipation area of the heat sink, the heat sink may be directly pressed and held on the top wall of the housing by a pair of elastic cross members. The two sides of the elastic clip are respectively provided with a hook, and the top wall of the shell is provided with a corresponding buckle. When the hooks of the spring clip snap into the snaps on the housing, the heat sink is locked to the top wall of the housing. However, in this solution, the hooks on both sides of the elastic clip need to be snapped into the corresponding snaps from the inside of the snaps. Therefore, when the elastic clamp is pressed downwards, the middle part of the elastic clamp can abut against the radiator, and the two sides can contract and deform towards the inner side, so that the clamping hooks on the two sides of the elastic clamp cannot be easily clamped in the clamping grooves of the clamping hooks on the outer side of the elastic clamp, the clamping hooks need to be pulled outwards by using an independent tool, and the clamping hooks can be clamped in the clamping grooves, so that the mounting difficulty of the elastic clamp is increased, and the radiating fins of the radiator with the thin thickness are easily damaged in the process of pulling the clamping hooks.
