Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicone button technology, and in particular to a self-positioning embedded structure for conductive particles in silicone buttons. Background Technology
[0002] When self-positioning conductive particles in silicone buttons, a self-positioning inlay structure is often used. This structure pre-designs conductive particles in specific positions and embeds them into the silicone button. Its advantages include improved production efficiency, ensuring the consistency and stability of conductivity, and enhancing product reliability and durability. The main reason for using this structure is to simplify the manufacturing process, reduce manual intervention, and ensure the accurate conductivity of each button, thereby improving the overall product quality and performance.
[0003] The self-positioning inlay structure of conductive particles in silicone buttons involves mixing conductive particles, such as metal powder or conductive rubber particles, with uncured silicone. The mixture is then injected into a mold. Inside the mold, recesses or protrusions of specific shapes and positions are designed to precisely position the conductive particles. Once the silicone material cures, the conductive particles are fixed in their predetermined positions, forming a button structure with conductive function. This self-positioning inlay method ensures the accurate placement of conductive particles in the silicone button, thereby guaranteeing the button's electrical performance and mechanical stability.
[0004] In the existing technology, some silicone button conductive particle self-positioning embedding structures use a simple mechanical pressing assembly method, which lacks a self-positioning function for the conductive particles. During the embedding process, due to the lack of an effective positioning mechanism, the conductive particles are difficult to accurately fall into the preset position of the silicone button, which easily leads to positional deviation, resulting in poor button contact, unstable conductivity, and reduced product yield. Therefore, a silicone button conductive particle self-positioning embedding structure is proposed to solve the above problems. Utility Model Content

[0032] The conductive mechanism includes an exhaust duct 11, which enables rapid air expulsion and intake during button pressing, ensuring a good operating feel while preventing internal pressure changes from affecting conductivity. A conductive plate 12 is fixedly connected to the internal space of the exhaust duct 11, which is the core component for circuit conduction, converting the mechanical signal generated by pressing into an electrical signal.

Extension 2 14 is fixedly connected to one side of the inner wall of extension 13, providing elastic buffering to ensure continuous and reliable contact between the conductive plate 12 and the circuit contacts. The exhaust duct 11 is located on the left and right sides of the bottom of the base 2.
[0033] Reference Figures 1 to 3 The adjustment component includes an insert block 7, the outside of which is fixedly connected to the inside of the insert groove 5.
