Description

Hot plug type interface connector

Technical Field

The present invention relates to a hot plug type interface connector, and more particularly, to a hot plug type interface connector having a plurality of conductive terminals.

Background

Gigabit interface connectors (GBICs) are hot-plugged input/output devices that plug into gigabit ethernet ports/slots, responsible for connecting the ports to the fiber optic network. GBIC can be used and interchanged on a variety of Cisco products and can be mixed with 1000BaseSX, 1000BaseLX/LH or 1000BaseZX interfaces compliant with IEEE 802.3z on a port-by-port basis. Furthermore, cisco is providing a 1000BaseLX/LH interface that is fully compliant with the IEEE 802.3z1000BaseLX standard, but that is traveling up to 10 kilometers over single mode fiber, 5 kilometers farther than the normal 1000BaseLX interface. In summary, with the continued development of new functions, it will be easier to upgrade these modules to the latest interface technology, thereby enabling the customer investment to take maximum advantage.

These traditional plug-in designs have been successful in the past, but they tend not to achieve the industry's continuing goal of miniaturization. It is desirable to miniaturize transceivers to increase the port density associated with network connections such as distribution boxes, cable patch panels, wiring closet, and computer input/output (I/O). Conventional pluggable module configurations are not able to meet these parameter requirements. It is also desirable to increase port density and optimize the connection interfaces of the SFP modules.

A new standard has been published and is referred to herein as the hot plug (SFP) standard, which is an abbreviation for SMALL FORMPLUGGABLE, which can be simply understood as an upgraded version of GBIC. The SFP module volume is reduced by half compared with the GBIC module, and more than one time of port number can be configured on the same panel. Other functions of the SFP module are substantially identical to GBIC. Some switch manufacturers call SFP modules miniaturized GBICs (MINI-GBICs). The SFP module volume is reduced by half compared with the GBIC module, and more than one time of port number can be configured on the same panel. The other functions of the SFP module are essentially the same as GBIC.

In the prior art, a hot plug socket connector includes a cage and a heat dissipation module disposed above the cage. The top of the cage body is provided with a hollowed-out heat dissipation window, and when the butt joint module is inserted, the generated heat is subjected to heat dissipation function through the heat dissipation window by the heat dissipation module. However, a gap exists between the cage body and the heat dissipation module, so that the shielding performance of the hot plug socket connector is affected.

Accordingly, there is a need for an improvement over existing hot plug interface connectors that overcomes the deficiencies described in the prior art.
