[0006] In this conductive rubber button of the present invention, the mounting hole is provided with symmetrically arranged fixing parts, which are disposed on the first annular inclined surface and the second annular inclined surface.

[0007] In this conductive rubber button of the present invention, the elastic element is composed of an annular ring and multiple elastic arms that cooperate with the elastic part, and the annular ring and the elastic arms are connected by an arc segment.

[0008] In this conductive rubber button of the present invention, the conductive component is provided with a rod, the lower end of the rod is formed with a notch, and the notch is located between symmetrically arranged conductive ends.

[0011] The conductive rubber button of this invention has the following advantages: The conductive rubber button has a compact and ingenious design. An elastic element is incorporated inside the button body to ensure a certain degree of reset force, thus preventing insufficient elasticity of the button body itself. Simultaneously, when pressed, it drives the conductive element in the middle, allowing it to move up and down with the button body, achieving a brief electrical connection. After the external force is removed, the button body, in conjunction with the elastic element, resets and disconnects the circuit. This extends the service life of the rubber button while reducing manufacturing costs, assembly difficulty, and the number of components used. Attached Figure Description

Detailed Implementation

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] like Figures 1 to 8As shown, this conductive rubber button of the present invention includes a button body 1, an elastic element 2, and a conductive element 3. The elastic element 2 is placed within the button body 1 during manufacturing, ensuring it is positioned in the center of the button body 1 during production, thus forming an integral structure with it. The conductive element 3 can be assembled into the center of the button body 1 later.

[0015] The button body 1 consists of a pressing part 4, a mounting part 5, and multiple elastic parts 6. The pressing part 4 is located at the upper end of the mounting part 5, and the elastic parts 6 are located at the lower end of the mounting part 5. A mounting hole 7 is formed in the middle of the button body 1, and the lower end of the mounting hole 7 is open to facilitate the insertion of the conductive component 3 into the mounting hole 7. The lower end of the button body 1 is also provided with a notch 30 for mounting with the device body 18.

[0016] A first annular inclined surface 8 and a second annular inclined surface 9 are provided in the mounting hole 7. The length of the first annular inclined surface 8 is less than the length of the second annular inclined surface 9. The first annular inclined surface 8 and the second annular inclined surface 9 are inclined in opposite directions. A first limiting annular groove 10 is formed between the first annular inclined surface 8 and the second annular inclined surface 9. A second limiting annular groove 11 is provided on the second annular inclined surface 9.

[0017] A symmetrically arranged fixing part 12 is provided in the mounting hole 7. The fixing part 12 can restrict the rotation of the conductive part 3 so that it will not be displaced. The fixing part 12 is provided on the first annular inclined surface 8 and the second annular inclined surface 9.

[0018] The elastic element 2 is disposed inside the button body 1, and is enclosed in the middle of the button body 1 to form an integral structure. The elastic element 2 consists of an annular ring 13 and multiple elastic arms 14 that cooperate with the elastic part 6. The annular ring 13 and the elastic arms 14 are connected by an arc-shaped segment 15. Through holes 16 are provided on the elastic element 2 and the button body 1 to facilitate the fixing of them to the device body 18 with bolts 17.

[0019] like Figure 7 As shown, the device includes a device body 18 and a circuit board 19. The back of the circuit board 19 faces the conductive element 3. A first stepped hole 20 and a second stepped hole 21 are provided in the middle of the device body 18. The inner diameter of the first stepped hole 20 is larger than the inner diameter of the second stepped hole 21, allowing the button body 1 to be placed within the first stepped hole 20 and then supported and limited by the second stepped hole 21. It is then installed onto the device body 18 using bolts 17. Symmetrically arranged conductive blocks 22 are provided on the back of the circuit board 19. When the conductive element 3 is pressed down, it electrically connects the two conductive blocks 22, ensuring the circuit connection. This is one circuit, while the other circuit remains connected.

[0020] The conductive element 3 is located in the middle of the button body 1. A fixed end 23 is located at the upper end of the conductive element 3, and symmetrically arranged conductive ends 24 are located at the lower end. A rod 25 is provided on the conductive element 3, with a notch 26 formed at the lower end of the rod 25, positioned between the symmetrically arranged conductive ends 24.

The fixed end 23 is also provided with a fixing groove 29 that mates with the fixing part 12. The fourth annular inclined surface 28 is provided with an annular protrusion 31 that mates with the second annular groove 11.

[0022] like Figure 8 As shown, when the button body 1 is pressed, the button body 1 is deformed downwards, thereby keeping the conductive end 24 in contact with the conductive block 22, realizing the electrical connection between the two conductive blocks 22, thereby controlling the operation of the device. This rubber button is a structure that needs to be pressed to be energized, so it can play a good power-on start-up effect for devices that are only briefly powered on.
