Abstract

The invention discloses a waterproof patched elastic key, comprising a base and a key soft body, wherein the key soft body comprises a key boss, an elastic soft body and a conductive contact; the elastic soft body is in the shape of a conical cylinder, the inner edge of the small opening of the elastic soft body is connected with the key boss, the big opening end of the elastic soft body is connected with the upper surface of the base, and a through hole corresponding to the big opening end of the elastic soft body in size is formed in the base; the conductive contact is arranged on the lower end face of the key boss; and the elastic key is characterized in that a waterproof soft edge is formed on the outer side of the base, and at least one waterproof cavity is formed in the waterproof soft edge. An internal pin protruding downwards is arranged at the bottom of the base and is not exposed outside the base, the lower end face and the circumference of the internal pin are welding surfaces, and welding gaps are formed on the circumference of the internal pin. The key has good waterproof performance, simple structure and low manufacturing cost.

Description

Technical field [0001] The invention relates to the application structure design technology of a polymer elastomer button, in particular to a waterproof patch type elastic button. Background technique [0002] The conductive adhesive button industry is an industry that was born in the 1980s and 1990s. In view of the problem that traditional non-standard monomer silicone buttons are not suitable for surface mount technology, surface mount type silicone buttons are proposed, that is, a pin bracket is added to the silicone button base, and a set of SMD silicone buttons are formed by molding; however, , On the one hand, facing high-density and high-integration applications, because the pins are exposed to the edge of the button during soldering, it is impossible to meet the requirements of high-density applications without gaps; on the other hand, in waterproof applications, the existing stickers The chip silicone button has not yet solved the structural design problem well, and the...
