Connector housing and heat sink combination structure

The present invention provides a connector housing and a heat sink assembly structure, and more particularly to a connector housing and a heat sink assembly structure for a small form factor pluggable module.

Conventional transceiver modules are commonly used to connect circuit boards and other electrical modules or devices of communication lines. Different industry standards define connector types for different interfaces between a computer and an external communication device such as a data machine, a network interface, or other transceiver modules. The well-known GBIC (Gigabit InterfaCe Converter) is a transceiver module that communicates with a computer, Ethernet, Fibre Channel or other data communication environment.

In order to increase the port density when interconnecting network devices (such as switches, cable patch panels, distribution boxes, computer output/input ports, etc.), it is often desirable to miniaturize the transceiver module. The development of the Quad Small Form-Factor Pluggable (QSFP) module is in line with this need. The main advantage is that the QSFP module is smaller than the GBIC transceiver module, which makes the communication system higher. density.

A heat sink can be disposed on the housing of the conventional small pluggable module connector to assist in heat dissipation. The heat sink can be assembled to the housing of the connector by means of lateral fastening or front and rear fastening. However, the conventional heat sink must be fastened to the opening of the casing by the fastening member, and the arrangement of the opening may cause the shielding effect of EMI to be reduced. Moreover, it is conventionally known that the fastening members that are fastened before and after are weak in strength, and are also easily damaged by external force and are easily released.
