[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] In order to form a multi-interface structure, the existing SFP network connector has a middle spacer in its shielding shell, and the front end of the middle spacer needs to be assembled with a spring sheet, and the front end of the middle spacer has a covering section and a through slot, and the through slot is located behind the covering section; the spring sheet includes a covering portion, two elastic portions and two connecting portions; the covering portion covers the front end of the covering section, and the two elastic portions extend from the two ends of the covering portion respectively, and the two elastic portions are respectively located outside the two sides of the rear end of the covering section, and the two connecting portions extend from the rear ends of the two elastic portions respectively, and the two connecting portions are fitted and fixed together and located in the through slot.

[0004] In the prior art, the two connecting parts are fixed by welding or riveting. Welding refers to laser welding on the two connecting parts after assembly in the post-process, which has a particularly high processing cost; while riveting is riveting with riveting columns and riveting holes, and lacks a positioning mechanism, so the fixing structure is not firm. Therefore, it is necessary to study a solution to solve the above problems. Utility Model Content

[0008] As a preferred solution, the aforementioned positioning hole and rivet sheet are punched out on one of the connecting parts, and correspondingly, the positioning column and rivet hole are punched out on the other connecting part. The structure is simple, the production is easy, and the structural strength is guaranteed.

[0009] As a preferred solution, the positioning hole and the positioning column are respectively located in the middle of the two connecting parts. There are two rivet plates and two rivet holes. The two rivet plates are respectively located on both sides of the positioning hole, and the two rivet holes are respectively located on both sides of the positioning column. The structure is simple and the connection is more stable and reliable.

[0010] As a preferred solution, the positioning hole is a round hole, and the corresponding positioning column is a round column, which is simple to shape and easier to position.

[0011] As a preferred solution, the rivet hole is in the shape of an elongated strip, so that the rivet sheet can be inserted therein, and the riveting is more stable.

[0012] As a preferred solution, the through groove is in the shape of an isosceles trapezoid, and correspondingly, the two connecting parts are also in the shape of an isosceles trapezoid, so as to be better positioned in the through groove.

[0013] As a preferred solution, a plurality of strip-shaped holes are formed through the inner and outer side surfaces of the two elastic parts. The plurality of strip-shaped holes are arranged in parallel at intervals and extend forward and backward, so as to make the elastic parts more elastic.
