Description

Technical Field

[0001] This utility model relates to the field of silicone button technology, specifically a highly conductive silicone button structure. Background Technology

[0002] Silicone pressing parts are pressing parts products made from silicone, belonging to a category of silicone products. Silicone pressing parts have excellent heat resistance, cold resistance, environmental resistance, electrical insulation, and fatigue resistance.

[0003] The top of the existing silicone pressing part is located outside through the perforation of the shell for easy pressing. However, the silicone pressing part and the perforation are not tightly attached, so dust can enter the interior of the shell through the perforation, affecting the internal components. In addition, the silicone pressing part rebounds through its own elasticity during use, but its own elasticity is weak and sometimes it cannot rebound, causing the pressing part to fail and the actual use effect is poor. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a highly conductive silicone button structure, which solves the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a highly conductive silicone button structure, including a connecting piece, the top of which is integrally formed with multiple pressing parts, a silicone block is fixed inside the pressing part, a conductive black dot is fixed at the bottom of the silicone block, a groove is integrally formed on the outer wall of the pressing part, an expansion mechanism is provided inside the groove, the expansion mechanism includes a fixing ring, an expansion sealing ring is fixed inside the fixing ring, and a spring is fixed on the inner side wall of the fixing ring.

[0006] Preferably, the outer wall of the expansion sealing ring is integrally formed with a protrusion.

[0007] Preferably, the cross-section of the protrusion is triangular.

[0008] Preferably, the retaining ring is made of hard plastic.

[0009] Preferably, the pressing part is provided with a reset mechanism, which includes a plurality of elastic sheets. The outer side wall of the silicone block is provided with an annular groove. The bottom end of the elastic sheet is located inside the annular groove, and the upper end of the elastic sheet passes through the pressing part and is fixedly connected to the inner side wall of the fixing ring.

[0010] Preferably, the inner upper surface of the annular groove is an inclined surface. Beneficial effects

[0011] This invention provides a highly conductive silicone button structure. Compared with the prior art, it has the following advantages:

[0012] 1. This high-conductivity silicone button structure, by setting an expansion mechanism, allows the pressing part to pass through the housing perforation. The spring presses the expansion sealing ring outward, and the expansion sealing ring is tightly attached to the inner side wall of the housing perforation. This can prevent dust from entering the interior of the housing through the perforation and affecting the internal components.

[0013] 2. This highly conductive silicone button structure, by setting a reset mechanism, when the pressing part is pressed, the pressing part squeezes the elastic sheet through the annular groove. When the pressing part is released, the elastic sheet will return to its original position along with the pressing part. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a highly conductive silicone button structure, including a connecting piece 1, the top of the connecting piece 1 is integrally formed with multiple pressing parts 2, a silicone block 6 is fixed inside the pressing part 2, a conductive black dot 4 is fixed at the bottom of the silicone block 6, a groove 7 is integrally formed on the outer wall of the pressing part 2, an expansion mechanism 3 is provided inside the groove 7, the expansion mechanism 3 includes a fixing ring 303, an expansion sealing ring 302 is fixed inside the fixing ring 303, and a spring 304 is fixed on the inner side wall of the fixing ring 303, so as to seal the inner side wall of the housing perforation and prevent dust from entering.

[0021] Preferably, the outer wall of the expansion sealing ring 302 is integrally formed with a protrusion 301, which can block the outside of the housing perforation and further improve the sealing performance.

[0022] Preferably, the cross-section of the protrusion 301 is triangular, which makes it easy to squeeze the protrusion 301 through the housing perforation.
