Description

Technical Field

[0001] This utility model relates to the field of capacitor grounding structure technology, and in particular to a metal elastic grounding component for capacitors. Background Technology

[0002] Capacitors are widely used components in household appliances, power systems, and electronic equipment for starting, running, filtering, energy storage, coupling, etc. Grounding is crucial to ensure their safe and stable operation.

[0003] Traditional capacitor grounding methods mostly involve bolts or welded grounding wires, but bolt grounding and welding methods have problems such as inconvenient installation, inconvenient disassembly, and high maintenance difficulty. Utility Model Content

[0004] To address the technical problems existing in the background art, this utility model proposes a metal elastic grounding component for capacitors.

[0005] The present invention proposes a metal elastic grounding component for capacitors, comprising a horizontally arranged first plate and two second plates respectively fixed on both sides of the first plate and extending downward. The first plate has a through hole, and each of the two second plates has a protrusion on the opposite side. The bottom end of the protrusion has a first abutment surface, and the second plate has a second abutment surface on the second plate and below the first abutment surface.

[0006] Preferably, the second plate includes an upper plate portion and a lower plate portion in its length direction. The end of the upper plate portion away from the first plate portion is inclined downward, and the end of the lower plate portion away from the upper plate portion is inclined upward. The protrusion is located on the upper plate portion, and the second abutment surface is located on the lower plate portion.

[0007] Preferably, a notch is provided at the connection between the lower plate body and the upper plate body.

[0008] Preferably, the protrusion is formed by cutting a portion of the upper plate body and bending it outward.

[0009] Preferably, a third plate is also fixed vertically downward on the first plate.

[0010] Preferably, the first plate, the second plate, and the third plate are integrally formed.

[0011] Preferably, the through hole is a stepped hole with the flared end facing upwards.

[0012] The metal elastic grounding component proposed in this utility model is fixedly connected to the studs on the capacitor by bolts during assembly. Then, the grounding component passes through the opening in the grounding metal mounting plate. The first abutting surface abuts against the top wall of the metal mounting plate, and the second abutting surface abuts against the bottom wall of the metal mounting plate, thereby fixing the grounding component and the metal mounting plate relatively in the vertical direction. The assembly method is simple and quick, and easy to disassemble. In addition, the second plate on the grounding component is elastic, which not only facilitates installation but also meets the needs of metal mounting plates of different thicknesses, thus expanding its assembly range.

[0016] Reference Figure 1 The present invention proposes a metal elastic grounding component for capacitors, comprising a horizontally arranged first plate 1 and two second plates 2 respectively fixed on both sides of the first plate 1 and extending downward. The first plate 1 has a through hole 11, and each of the two second plates 2 has a protrusion 21 on the opposite side. The bottom end of the protrusion 21 has a first abutment surface, and the second plate 2 has a second abutment surface located below the first abutment surface.

[0017] The specific installation process of the proposed metal elastic grounding component is as follows: During installation, the through hole 11 on the grounding component is fitted onto the stud 41 on the capacitor 4, and the screw 5 is screwed into the internal thread hole on the stud 41 to fix the grounding component onto the stud 41. See details below. Figure 2 Additionally, the stud 41 has a vertical plane. To prevent the grounding component from rotating, a vertically downward third plate 3 is fixed to the first plate 1. The third plate 3 fits against the vertical plane on the stud 41, thus preventing the grounding component from rotating together when the screw 5 is turned. Then, the grounding component passes through the opening on the grounding metal mounting plate 6, which is connected to a ground wire. The first abutting surface abuts against the top wall of the metal mounting plate 6, and the second abutting surface abuts against the bottom wall of the metal mounting plate 6. See the details below. Figure 3 This allows the grounding component and the metal mounting plate 6 to be fixed relatively in the vertical direction.

[0018] In the above embodiment, the second plate 2 includes an upper plate portion 22 and a lower plate portion 23 in its length direction. The end of the upper plate portion 22 away from the first plate portion 1 is inclined downward, and the end of the lower plate portion 23 away from the upper plate portion 22 is inclined upward. The protrusion 21 is located on the upper plate portion 22, and the second abutment surface is located on the lower plate portion 23. In use, based on the elasticity of the grounding member itself, the angle between the lower plate portion 23 and the upper plate portion 22 is adjustable, so that the grounding member can meet the usage requirements of metal mounting plates 6 of different thicknesses, and make it fit tightly with the metal mounting plate 6 according to its own elasticity.

[0019] To increase the elasticity of the grounding component, a notch 231 is provided at the connection between the lower plate body 23 and the upper plate body 22.

[0020] In the above embodiment, in order to reduce material costs and increase the elasticity of the grounding component, the protrusion 21 is formed by cutting a portion of the upper plate body 22 and bending it outward.

[0021] It should be further explained that the first plate 1, the second plate 2, and the third plate 3 are integrally formed.

[0022] In the above embodiment, the through hole 11 is specifically a stepped hole with the flared end facing upwards.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
