The spring plays an important role in switches, battery boxes, power distribution units (PDU) and printed circuit boards (PCB), and is mainly used to realize reliable connection of circuits, provide stable grounding support and efficient signal transmission.

[0003] However, the existing conductive spring often gradually loses its elasticity during long-term use, especially after frequent mechanical pressing. This decrease in elasticity directly leads to a significant decrease in performance, which can affect the reliable connection of circuits, not only affecting the stable transmission of signals, but also causing instability in the operation of the device, further increasing the risk of failure and maintenance costs.

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1 As shown in the figure, this application discloses a compression spring, including: a fixing part 100, one end of which is provided with an inclined protruding first connecting part; the first connecting part 200 is provided with a first support part 300 at one end opposite to the fixing part 100; the other end of the fixing part 100 is provided with an inclined protruding second connecting part 400; the second connecting part 400 is provided with a second support part 500 at one end opposite to the fixing part 100; the first support part 300 and the second support part 500 are elastic.

[0025] In use, the fixing part 100 serves as the welding area or adhesive bonding area for the assembly, primarily for fixation. The first support part 300 and the second support part 500 are the compression contact areas for the assembly. During assembly, other assemblies are tightly fitted against the first support part 300 and the second support part 500, and then compressed downwards, thereby achieving electrical conductivity. When the first support part 300 and the second support part 500 are compressed downwards, the first connecting part 200 and the second connecting part 400 move inwards. Thus, the first connecting part 200 and the second connecting part 400 isolate the assemblies from each other to avoid interference and effectively shield electromagnetic interference.

[0026] Specifically, in actual use, the first support portion 300 is parallel to the fixed portion 100; the second support portion 500 is parallel to the fixed portion 100. When the assembly compresses the first support portion 300 and the second support portion 500, the parallel structure not only provides a more uniform supporting force, enabling the spring to stably bear the load during operation, but also enhances the overall stability of the spring structure. Through uniformly distributed force, the spring can maintain its shape and function during long-term use, avoiding deformation or damage caused by stress concentration, and ensuring a continuous and stable electrical connection during use, preventing a decrease in conductivity due to structural instability.

[0027] like Figure 1 As shown, in this embodiment, the fixing part 100, the first connecting part 200, and the first supporting part 300 are in a tri-fold shape; the fixing part 100, the second connecting part 400, and the second supporting part 500 are also in a tri-fold shape. Specifically, the two ends of the first connecting part 200 are respectively connected to the first supporting part 300 and the fixing part 100, and the two ends of the second connecting part 400 are respectively connected to the second supporting part 500 and the fixing part 100; the fixing part 100, the first supporting part 300, the first connecting part 200, the second connecting part 400, and the second supporting part 500 are all in a tri-fold shape. When the assembly compresses the first supporting part 300 and the second supporting part 500, the first connecting part 200 and the second connecting part 400 move closer to each other to achieve a compact layout in a limited space; at the same time, it can withstand repeated use without easily deforming or being damaged, thus extending the service life of the spring.

[0028] In this embodiment, the fixing part 100, the first connecting part 200, the first supporting part 300, the second connecting part 400, and the second supporting part 500 are integrally formed, which effectively eliminates stress concentration points that may be caused by welding or riveting processes, so that the structure of the entire compression spring can better withstand greater mechanical stress, maintain a stable shape and function in long-term use, and ensure that the compression spring has stable electrical conductivity.

[0029] like Figure 1As shown, in another embodiment of this utility model, the angle between the surface of the first connecting part 200 and the surface of the fixing part 100 is less than 60 degrees; the angle between the surface of the second connecting part 400 and the surface of the fixing part 100 is less than 60 degrees. In use, the smaller angle makes the overall structure of the compression spring compact and occupies less space. Simultaneously, when compressing the first support part 300 and the second support part 500, the degree of bending of the first connecting part 200 and the second connecting part 400 is reduced, lowering the risk of structural damage to the first connecting part 200 and the second connecting part 400 due to excessive deformation.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, the first connecting portion 200 has a first slot 210 at one end near the first support portion 300; the first slot 210 extends to the first support portion 300. The second connecting portion 400 has a third slot 230 at one end near the second support portion 500; the third slot 230 extends to the second support portion 500. Both the first slot 210 and the third slot 230 are provided in multiples, and are staggered. In actual use, the assembly fits tightly against the first support portion 300 and the second support portion 500. The first slot 210 and the third slot 230 can increase the contact points with the assembly to improve contact stability.

[0031] In this embodiment, a second slot 220 is provided at one end of the first connecting portion 200 near the fixing portion 100; the second slot 220 extends to the fixing portion 100. A fourth slot 240 is provided at one end of the second connecting portion 400 near the fixing portion 100; the fourth slot 240 extends to the fixing portion 100. A plurality of second slots 220 and fourth slots 240 are provided, and the second slots 220 and fourth slots 240 are arranged opposite to each other. In use, the fixing portion 100 is installed on sheet metal parts or other assemblies by soldering or adhesive backing, compressing the first support portion 300 and the second support portion 500 downwards, causing the first connecting portion 200 and the second connecting portion 400 to move inwards. The second slots 220 and fourth slots 240 can effectively help disperse and reduce stress concentration during use, reduce the risk of spring fatigue and breakage, and extend service life.

[0032] like Figure 2As shown, in actual use, the opening size of the first slot 210 and the third slot 230 is larger than the opening size of the second slot 220 and the fourth slot 240. While reducing the overall weight of the spring sheet, the stability and deformation resistance of the structure are enhanced by reasonably distributing the slot size, ensuring stable conductivity while reducing processing difficulty and cost.

[0033] In summary, this application discloses a compression spring, comprising: a fixing part, with a first connecting part extending obliquely at one end; a first supporting part at the end of the first connecting part opposite to the fixing part; a second connecting part extending obliquely at the other end of the fixing part; and a second supporting part at the end of the second connecting part opposite to the fixing part; the first supporting part and the second supporting part are elastic. By providing the first connecting part and the second connecting part between the fixing part and the first and second supporting parts, compression of the first and second supporting parts drives compression of the first connecting part and the second connecting part, thus conducting the assembly. This optimizes the structure and compression method of the conductive spring support component, ensuring that the spring can achieve a uniform force distribution when subjected to external force, enabling the device to maintain stable conductivity under different working conditions, and solving the problem of performance instability caused by uneven force on the conductive spring.

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0035] It should be noted that this utility model uses a compression spring as an example to introduce the specific structure and working principle of the utility model, but the application of this utility model is not limited to compression springs, and can also be applied to the production and use of other similar workpieces.

[0036] It should be understood that this invention is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
