Abstract
Description
Technical Field
[0001] This utility model relates to the field of wave springs, and in particular to a double wave spring with an insulating intermediate layer. Background Technology
[0002] A wave spring is an elastic element with multiple peaks and troughs on a thin metal ring, consisting of a thin-plate annular elastic metal unit composed of multiple peaks and troughs. This structure allows the wave spring to undergo elastic deformation and store energy when subjected to external force. A double wave spring is a composite material made of two or more wave springs of the same shape stacked together. The working principle of a double wave spring is similar to that of a single-layer wave spring, both based on the storage and release of elastic energy. When an external force is applied, the waveform of the double wave spring compresses or expands, thereby accumulating elastic energy. When the external force is removed, the spring returns to its original shape and releases the stored elastic energy. Due to the stacking of multiple wave springs, a double wave spring can provide higher stiffness and greater compression while maintaining a relatively smooth stroke. When double wave springs are used in electronics, power, and communications fields, a double wave spring with an insulating intermediate layer is needed to prevent short circuits caused by current flowing through the spring, ensure the normal operation and safety of equipment, reduce electric field interference, and improve the quality of signal transmission. Utility Model Content

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0005] A double wave spring with an insulating intermediate layer includes a double wave spring structure composed of multiple sets of wave spring components. Two mounting connection assemblies are symmetrically fixed at both ends of the double wave spring structure. Each mounting connection assembly consists of a rigid base ring and an annular rubber pad. The annular rubber pad is installed at the outer end of the rigid base ring. An annular central insulating layer is fixedly installed between the multiple sets of wave spring components. The annular central insulating layer consists of an annular ceramic insulating pad, an annular glass insulating pad, and an annular plastic insulating pad. There are two annular glass insulating pads, each installed at one end of an annular ceramic insulating pad. There are two annular plastic insulating pads, each installed at one end of a two annular glass insulating pad. Several buffer noise reduction components are symmetrically fixedly installed at one end of each of the two annular plastic insulating pads. Each buffer noise reduction component consists of a rubber connecting pad and a rubber airbag, with the rubber airbag installed at one end of the rubber connecting pad.
[0006] Preferably, the two adjacent wave spring components on the dual wave spring structure are fixedly connected.
[0007] Preferably, the rigid base ring and the annular rubber pad on the mounting connection assembly are fixedly connected, and the rigid base ring is fixedly connected to the wave spring component on the edge.
[0008] Preferably, the annular ceramic insulating pad and the annular glass insulating pad on the central insulating layer are fixedly connected, and the annular glass insulating pad and the annular plastic insulating pad are fixedly connected.

[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] By incorporating mounting connection components and an annular central insulation layer into the double wave spring structure, the annular rubber pad on the mounting connection component and the annular central insulation layer enhance the insulation performance of the double wave spring structure.

Detailed Implementation
[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a double wave spring with an insulating intermediate layer includes a double wave spring structure 1, which is composed of multiple sets of wave spring components 5 stacked together. Two mounting connection components 2 are symmetrically fixedly installed at both ends of the double wave spring structure 1. Each mounting connection component 2 consists of a rigid base ring 6 and an annular rubber pad 7. The annular rubber pad 7 is installed at the outer end of the rigid base ring 6. An annular central insulating layer 3 is fixedly installed between the multiple sets of wave spring components 5. The annular central insulating layer 3 consists of an annular ceramic insulating pad 8, an annular glass insulating pad 9, and an annular plastic insulating pad 10. There are two annular glass insulating pads 9, each installed at one end of the annular ceramic insulating pad 8. There are two annular plastic insulating pads 10, each installed at one end of the two annular glass insulating pads 9. Several buffer noise reduction components 4 are symmetrically fixedly installed at one end of each of the two annular plastic insulating pads 10. Each buffer noise reduction component 4 consists of a rubber connecting pad 11 and a rubber airbag 12. The rubber airbag 12 is installed at one end of the rubber connecting pad 11. Two adjacent wave springs on the double wave spring structure 1... Component 5 is a fixed connection. During installation, the mounting connection component 2, together with bolts, can be used to install and fix the double wave spring structure 1 onto the required equipment. When the double wave spring structure 1 is compressed, the waveform of the wave spring component 5 on the double wave spring structure 1 will be compressed or expanded, thereby accumulating elastic energy. When the external force disappears, the wave spring component 5 will return to its original shape and release the stored elastic energy. Finally, by setting the mounting connection component 2 and the annular central insulation layer 3 on the double wave spring structure 1, the annular rubber pad 7 on the mounting connection component 2 and the annular central insulation layer 3 can improve the insulation performance of the double wave spring structure 1, thereby effectively preventing short circuits and other faults caused by current passing through the double wave spring structure 1, ensuring the normal operation and safety of the equipment, reducing electric field interference, and improving the quality of signal transmission. By setting the buffer noise reduction component 4, the impact and friction between two adjacent wave spring components 5 can be reduced, thereby improving the service life of the double wave spring structure 1 and reducing the noise generated by the double wave spring structure 1 during use.
[0020] Furthermore, the rigid base ring 6 and the annular rubber pad 7 on the mounting connection assembly 2 are fixedly connected. The rigid base ring 6 is fixedly connected to the wave spring component 5 on the edge. The annular ceramic insulating pad 8 and the annular glass insulating pad 9 on the annular central insulating layer 3 are fixedly connected. The annular glass insulating pad 9 and the annular plastic insulating pad 10 are fixedly connected. The annular plastic insulating pad 10 on the annular central insulating layer 3 is fixedly connected to the wave spring component 5 in the middle. During use, the annular rubber pad 7 on the mounting connection assembly 2 and the annular ceramic insulating pad 8, annular glass insulating pad 9, and annular plastic insulating pad 10 on the annular central insulating layer 3 can provide insulation, thereby ensuring that the double wave spring structure 1 has a certain insulation performance.
[0021] Furthermore, the rubber connecting pad 11 on the buffer noise reduction component 4 is fixedly connected to the annular plastic insulating pad 10, and the rubber connecting pad 11 and the rubber airbag 12 are fixedly connected. When the waveform of the wave spring component 5 is compressed, the rubber connecting pad 11 and the annular plastic insulating pad 10 on the buffer noise reduction component 4 can block the two adjacent wave spring components 5, thereby reducing the impact and friction between the two adjacent wave spring components 5, thus reducing the wear of the wave spring components 5, and ultimately improving the service life of the wave spring components 5, thereby improving the service life of the double wave spring structure 1. At the same time, it can also reduce the noise generated by the collision of the two adjacent wave spring components 5 when the double wave spring structure 1 is in use.
