Technical Field

[0001] The utility model relates to the technology of the network connector field, in particular to a bending and fixing structure of a lower shell of an SFP network connector. Background Art

[0002] SFP can be simply understood as an upgraded version of GBIC. It is an interface device that converts gigabit electrical signals into optical signals and can be hot-swapped. GBIC is an interchangeable product that complies with international standards. Gigabit switches designed with GBIC interfaces have a large market share in the market due to their flexible interchangeability. SFP modules further compress the size and power consumption by placing CDR and electrical dispersion compensation outside the module. They are used in optical communication applications in telecommunications and data communications. SFP connects the motherboards of network devices such as switches, routers and other devices with optical fibers or UTP cables. SFP is an industrial specification supported by some fiber optic device providers.

[0003] The shielding shell of the existing SFP network connector is mainly formed by assembling an upper shell and a lower shell. The upper shell includes a top plate and two side plates. The two side plates are bent downward and extended as a whole at both sides of the top plate. The front bottom of the two side plates is provided with an embedding groove; the lower shell is connected with the upper shell by a snap-fit ​​and encloses to form an accommodating cavity with an opening facing forward. Both sides of the front end of the lower shell are convexly provided with convex parts, and the convex parts are embedded in the embedding groove.
