Description

Technical Field

[0001] This utility model relates to the field of high-strength technology, specifically to a high-strength waterproof tactile switch. Background Technology

[0002] Tactile switches are widely used in consumer electronics, home appliances, and outdoor equipment. They generally employ a mechanical contact structure, and the button area typically has physical gaps, resulting in poor waterproof performance. In humid environments or situations involving liquid splashes, moisture, dust, and other foreign matter can easily penetrate the interior through the button gaps, causing problems such as contact oxidation, short circuits, or functional failures, severely affecting the reliability and lifespan of the switch. Utility Model Content

[0003] Therefore, the technical problem to be solved by this utility model is to overcome the defect of poor waterproof performance of existing tactile switches, thereby providing a high-strength waterproof tactile switch.

[0004] Therefore, this utility model provides a high-strength waterproof tactile switch, including a base, a dustproof film, a silicone pad, and a cover plate. The base has a receiving groove suitable for installing spring and contact assembly; the dustproof film is affixed to the top surface of the base and is used to cover the opening of the receiving groove; the silicone pad is disposed above the dustproof film; and the cover plate is assembled with the base and presses the silicone pad tightly to the base.

[0005] The opening edge of the receiving groove is provided with a protrusion.

[0006] The silicone pad is cross-shaped, and the base is formed with a positioning groove that matches the cross-shaped silicone pad.

[0007] The dustproof film is cross-shaped and adapted to the positioning groove.

[0008] The base has four corners with riveting posts, and the cover plate has through holes corresponding to the riveting posts. The cover plate and the base are riveted together and fixed by the riveting posts.

[0009] The contact assembly includes a first contact and a second contact disposed on both sides of the first contact, and the base is formed with a rib located between the first contact and the second contact.

[0010] The dustproof film is attached to the top of the base with adhesive.

[0011] The dustproof film is made of polyimide.

[0012] The technical solution of this utility model has the following advantages: 1. The high-strength waterproof tactile switch provided by this utility model includes a base, a dustproof membrane, a silicone pad, and a cover plate. The cover plate is assembled with the base, the silicone pad provides the first waterproof barrier, and the tight connection between the cover plate and the base ensures the stability and sealing reliability of the overall structure. The dustproof membrane serves as the second line of defense to isolate moisture and dust, thus forming a double-layer waterproof sealing structure. Compared with the prior art, this provides better waterproof sealing performance.

[0013] 2. The high-strength waterproof tactile switch provided by this utility model has a raised design on the edge of the receiving groove opening, which can form a higher local pressure when it is attached to the dustproof membrane, greatly enhancing the tightness of the sealing interface, effectively preventing liquid from seeping along the plane gap, and improving the waterproof level of key areas.

[0014] 3. The high-strength waterproof tactile switch provided by this utility model, with the cooperation of the cross-shaped silicone pad and the positioning groove, and the corresponding shape of the dustproof film, achieves precise radial positioning, which can effectively prevent the silicone pad from shifting or twisting under repeated pressing, ensuring that the pressing feel is always consistent, and protecting the dustproof film from damage due to misalignment and friction, thus extending its service life.

[0015] 4. The high-strength waterproof tactile switch provided by this utility model has a raised rib between the first contact piece and the second contact piece, which constitutes a reliable electrical isolation barrier. Attached Figure Description
