[0026] Figure 6 for Figure 5 A schematic diagram of the exploded structure of the pressure device in the middle; Detailed Implementation

[0027] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0028] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a spring module structure 11 includes: a spring housing 100, a pressure cover 200, and a spring component 300; the spring housing 100 is provided with a first receiving cavity, and the pressure cover 200 is provided with a second receiving cavity, the first receiving cavity and the second receiving cavity are combined to form the receiving cavity of the spring component 300; a limiting snap-fit ​​structure 110 is provided at one end of the spring housing 100 facing the pressure cover 200, and a limiting boss 210 is provided at one edge of the pressure cover 200 facing the spring housing 100; when the spring housing 100 and the pressure cover 200 are combined and connected, the limiting boss 210 is located within the limiting snap-fit ​​structure 110.

[0029] It should be noted that traditional spring module structures used in pressure devices are relatively complex, with a large number of parts, requiring welding during assembly. Given the relatively large quantity of spring modules used, employing welding not only leads to low processing efficiency but also increases costs. For example... Figure 1As shown, this is a spring module structure before improvement. The spring housing of this spring module structure is a separate structure, that is, it includes an upper housing A and a lower housing B. The upper housing A and the lower housing B need to be assembled together by positioning with an electric welding fixture in order to fix the pressure cap 200 and the spring component 300. This assembly structure is not only inefficient in production, but also requires a lot of parts and is not simple enough. Therefore, this utility model provides a limiting snap-fit ​​structure 110 on the spring housing 100 and a corresponding limiting boss 210 on the pressure cap 200. The limiting snap-fit ​​structure 110 and the limiting boss 210 form a physical snap-fit ​​engagement, thereby assembling and fixing the spring housing 100, the pressure cap 200, and the spring component 300. In this way, the traditionally separate upper and lower parts of the spring housing can be combined into a single spring housing 100, reducing the number of parts used. This not only simplifies the structure but also replaces the traditional method of assembly and fixing through electric welding, enabling rapid assembly of the spring module structure 11, improving production efficiency, and reducing costs.

[0030] Furthermore, the limiting latching structure 110 includes a connecting protrusion 111 and a limiting latching portion 112. One end of the connecting protrusion 111 is disposed on the open end face of the spring housing 100, and the other end of the connecting protrusion 111 extends away from the open end face. One end of the limiting latching portion 112 is disposed on the other end of the connecting protrusion 111, and the free end of the limiting latching portion 112 extends towards the central axis of the spring housing 100. The limiting latching portion 112 abuts against the limiting boss 210.

[0031] It should be noted that the free end of the limiting boss 210 on the pressing cover 200 extends in a direction away from the central axis of the pressing cover 200. Meanwhile, by making the free end of the limiting clamping portion 112 extend in a direction toward the central axis of the spring housing 100, the opening inlet space of the spring housing 100 is reduced, which allows the pressing cover 200 to be clamped and fixed in the first accommodating cavity of the spring housing 100 via the limiting boss 210, and enables the limiting boss 210 to abut against the limiting clamping portion 112, thereby preventing the pressing cover 200 from falling off. The connecting protrusion 111 is provided to facilitate the processing of the limiting clamping structures 110. For example, in this embodiment, a plurality of limiting clamping structures 110 are provided, and each limiting clamping structure 110 is arranged at intervals around the periphery of the first accommodating cavity. The limiting clamping portion 112 is located on a side edge of the connecting protrusion 111, so it is necessary to provide the connecting protrusion 111 to keep the limiting clamping portion 112 in a suspended state, and meanwhile, each limiting clamping structure 110 is arranged at intervals, so that a bending die can perform bending processing on the limiting clamping portion 112 from the side edge. In another embodiment, the limiting clamping structure 110 may also only include the limiting clamping portion 112, each limiting clamping portion 112 is arranged at intervals, and the free end of the limiting clamping portion 112 is bent toward the central axis of the spring housing 100. In this embodiment, the spring housing 100 and the limiting clamping structures 110 are of an integrated structure, so as to ensure the strength of the limiting clamping structures 110.

[0032] Further, two limiting clamping portions 112 are provided in one same limiting clamping structure 110. In this way, by increasing the number of the limiting clamping portions 112, the number of pressing points between the limiting boss 210 and the limiting clamping portions 112 is increased, thereby ensuring more uniform stress.

[0033] Further, the diameter of the outermost ring of the limiting boss 210 on the pressing cover 200 is smaller than the diameter of the first accommodating cavity of the spring housing 100. In this way, the limiting boss 210 on the pressing cover 200 can be quickly squeezed into the first accommodating cavity of the spring housing 100 through the limiting clamping structures 110 on the spring housing 100, and the limiting clamping and fixing of the limiting boss 210 is realized via the limiting clamping structures 110. During assembly, a corresponding assembly fixture can be used to realize rapid positioning assembly, which improves assembly efficiency.

[0034] In one embodiment, the spring housing 100 includes an installation limiting table 120 and a pressing protrusion 130, the limiting clamping structures 110 are provided on the installation limiting table 120, and the size of the pressing protrusion 130 is smaller than the size of the installation limiting table 120, so that the cross-section of the spring housing 100 has a convex-shaped structure.

[0035] It should be noted that the size of the holding boss accommodating cavity on the holding boss 130 is adapted to the size of the elastic member 300, and meanwhile, the size of the second accommodating cavity on the pressing cover 200 is also adapted to the size of the elastic member 300. Two ends of the elastic member 300 are respectively located in the holding boss accommodating cavity and the second accommodating cavity, and the elastic member 300 is positioned through the holding boss accommodating cavity and the second accommodating cavity, so as to avoid the problem that the elastic member 300 is displaced in a non-compression direction, which affects the holding effect. By arranging the installation limit table 120 and making the size of the holding boss 130 smaller than the size of the installation limit table 120, that is, making the diameter of the holding boss 130 smaller than the diameter of the installation limit table 120, so that the cross-section of the spring housing 100 forms a "convex"-shaped structure with an unclosed bottom, which is convenient for subsequent quick alignment and assembly of the spring module structure 11 to form the presser 10, and improves the assembly efficiency of the presser 10.

[0036] In one embodiment, the elastic member 300 includes a mandrel 310 and a spring body 320, and the spring body 320 is sleeved on the mandrel 310. The structure of a single spring without the mandrel 310 will lead to uneven pressure transmission and the problem that the spring is prone to bending. Therefore, by sleeving the spring body 320 on the mandrel 310, axial support is provided for the spring body 320, so as to avoid the risk of serious bending deformation of the spring when stressed, and ensure the working reliability of the presser 10. In this embodiment, the length of the spring body 320 is greater than the length of the mandrel 310.

[0037] A presser 10 includes the above-mentioned spring module structure 11, and further includes a top plate 12 and a lower cover 13. The lower cover 13 is provided with an installation cavity, the top plate 12 is arranged at an opening side of the lower cover 13, a side of the lower cover 13 away from the top plate 12 is provided with an installation escape hole 13a, the spring module structure 11 is installed in the installation cavity, and a part of the spring housing 100 passes through the installation escape hole 13a and protrudes relative to the surface of the lower cover 13.

[0038] It should be noted that an installation cavity is provided on the lower cover 13 to accommodate and install the spring module structure 11, and the top plate 12 is matched to limit and fix the spring module structure 11; the installation escape hole 13a is provided on the lower cover 13 to allow a part of the spring housing 100 to be exposed, and here the holding boss 130 of the spring housing 100 is exposed. The installation limit table 120 of the spring housing 100 abuts against the inner wall of the lower cover 13, thereby facilitating rapid alignment assembly and positioning of the spring housing 100. The holding boss 130 abuts against a connector to apply a pressing force to the connector. The pressing cover 200 can be made of elastic rubber material. In this embodiment, the top plate 12 and the lower cover 13 can be connected and fixed by electric welding, screw connection or gluing.

[0039] Furthermore, the top plate 12 is provided with a mounting positioning groove 12a, and the pressure cap 200 is partially located within the mounting positioning groove 12a. The mounting positioning groove 12a is used to position the pressure cap 200. The mounting positioning groove 12a can prevent the pressure cap 200 from being misaligned. Thus, by using the mounting positioning groove 12a in conjunction with the mounting clearance hole 13a, the positional accuracy of the spring module structure 11 within the pressure device 10 can be ensured, which also facilitates quick alignment during assembly and reduces adjustment time.

[0040] Furthermore, the edge of the top plate 12 is provided with a mounting protrusion 12b, the free end of which extends away from the spring module structure 11. A mounting hole 12c is provided on the mounting protrusion 12b for mounting the screw connector 14. The screw connector 14 facilitates the connection and fixation of the pressure device 10 to the PCB board; the size of the mounting hole matches the screw connector, and the extension direction of the mounting protrusion 12b ensures no interference during screwing. The mounting protrusion 12b also enhances the connection strength.

[0041] Furthermore, multiple spring module structures 11 are provided, and each spring module structure 11 is arranged at intervals within the mounting cavity. Depending on actual needs, the pressure unit 10 typically has one or more spring module structures 11; for example, the pressure unit 10 may have 1-hole, 6-hole, 7-hole, 16-hole, 32-hole, and 64-hole pressure units. One spring module is installed in each hole. Pressure units 10 with different numbers of holes are adapted to servers with different requirements. The interval arrangement of multiple spring module structures 11 also ensures pressure uniformity, avoiding poor contact problems in the connectors due to uneven pressure.

[0042] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
