Description

Technical Field

[0001] The utility model relates to the technology of the SFP network connection field, in particular to a window fixing structure of an SFP network connector shielding case. Background Art

[0002] In data communication and telecommunication lines, an SFP module is plugged and assembled with a corresponding interface socket on a communication system to achieve signal connection. The Small Form-Factor Pluggable (SFP) module is a common optical / electrical communication transceiver module, which has the characteristics of hot pluggability, easy maintenance and replacement, and small size. In order to quickly realize the hot plugging of the above SFP module, an SFP network communication connector structure is usually set for the SFP module, so as to realize the functions of quick buckling and quick unbuckling connection with the corresponding interface socket on the communication system.

[0003] The existing SFP network connector shielding case adopts an assembly structure of an upper case and a lower case, and the front ends of the upper case and the lower case enclose to form a window; at present, there are mainly two structures for the combination of the front ends of the upper case and the lower case: one is clearance fit, and this structure makes the window have the risk of loosening and opening deformation, and the structure is not stable. The other is to adopt dovetail riveting, and this structure process is too complex, the assembly is too troublesome, and it is necessary to flatten and punch riveting points first and then spot weld during production, and the production efficiency is very low and the cost is also very high. Therefore, it is necessary to improve the current SFP network connector shielding case. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide a window fixing structure of an SFP network connector shielding case, which can effectively solve the problems of unstable structure, low production efficiency and high cost existing in the current SFP network connector shielding case.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A window fixing structure of an SFP network connector shielding case includes an upper case and a lower case; the upper case and the lower case are spliced and fixed together up and down, and the front ends of the upper case and the lower case enclose to form a window; the front end of the upper case is in an inverted U shape, which includes two side plates and a top plate integrally formed and connected between the tops of the two side plates, and openings facing downwards are formed at the bottoms of the two side plates, and the openings penetrate the inner and outer sides of the side plates; the front end of the lower case is in a flat plate shape, and convex cards extend outwards from both sides of the front end of the lower case, and the convex cards are interference-fitted with the openings to be buckled and fixed.

[0007] As a preferred solution, arc-shaped inverted buckle structures are formed on the bottom edges of the front and rear sides of the slot, and the two inverted buckle structures are buckled with the bottoms of the two sides of the protrusion to make the installation more stable.

[0008] As a preferred solution, the depth of the single-sided interference between the protrusion and the groove is 0.03 mm, and the combination is more firm.

[0009] As a preferred solution, the card slots are multiple and evenly spaced from front to back, and correspondingly, the card protrusions are multiple and evenly spaced from front to back. The multiple card protrusions are respectively interfered with and snap-fitted with the corresponding card slots, so that the combination of the lower shell and the upper shell is more stable.

[0010] As a preferred solution, EMI shrapnel is riveted and fixed to the periphery of the window.

[0011] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0012] By opening downward-facing card slots at the bottom of both side panels, and cooperating with the flat front end of the lower shell, card protrusions extend outward on both sides of the front end of the lower shell, and the card protrusions are fixed by interference fit between the card protrusions and the card slots, there is no risk of the window loosening or opening and deformation. At the same time, this structure is very simple, the manufacturing process is simple, and the assembly is convenient, which effectively improves the assembly efficiency, and the cost is relatively low, so it is worthy of popularization and use.
