Technical Field

The present invention relates to a connector, and more particularly, to a connector applied to a small pluggable module and increasing a heat dissipation area.

Background

With the development of network information, the flow of network processing and management data is continuously increasing, so more and updated communication transmission technologies are continuously developed to provide faster transmission speed, longer transmission distance and efficient and safe transmission of data, and in order to increase the port Density when interconnecting with network devices, the development of miniaturized modules is mainly common, so the industry develops a dual-Density four-channel Small Form-factor Pluggable Double-Density (QSFP-DD) module to meet the above requirements.

However, with the continuous increase of the transmission rate, the energy used for transmitting signals is increased, and more heat is generated, so that the typical QSFP optical module can normally operate at the temperature of 70 degrees celsius, if the temperature exceeds 70 degrees celsius, the performance of the optical module will be reduced, and the service life will be shortened, and the requirements of the QSFP-DD for the relative temperature are lower due to the higher transmission rate, so in order to solve the heat dissipation problem, the roughness and the flatness of the QSFP-DD are improved, and the common solution is to open holes in the housing of the connector, but according to the current structural configuration, the open holes cannot be increased any more, so that the contact area between the heat dissipation fin base of the connector and the optical module can only be increased, and how to increase the contact area between the heat dissipation fin base of the connector and the optical module, so as to accelerate the heat dissipation effect is a problem that needs to be solved in industry.
