No-overhanging pin patch type silica gel elastic button

Abstract

The invention discloses a no-overhanging pin patch type silica gel elastic button comprising a pedestal and a button soft body. The button soft body comprises a button convex body, an elastic soft body and a conductive contact. The elastic soft body is a tapered cylinder shape. The small mouth internal edge of the elastic soft body is connected with the button convex body. The large mouth end of the elastic soft body is connected with the upper surface of the pedestal. The conductive contact is arranged at the lower end surface of the button convex body. The no-overhanging pin patch type silica gel elastic button is characterized in that the pedestal is internally provided with internal pins which do not exceed the external side of the pedestal. The lower end surfaces and the external side surfaces of the internal pins are welding surfaces. The internal pins are arranged on pin supports. Pin connecting frames connected with the internal pins are arranged between the internal pins. The internal pins and the pin connecting frames are included in the pin supports. The secondary bending process of pin welding is avoided by the button, and pin coplanarity is great so that the requirements for pin size, shape and number of different buttons can be simply realized. The button is suitable for application of surface mounting and also has advantages of high-density arrangement, low manufacturing cost and great practicality.

Description

technical field [0001] The invention relates to the structural design and application technology of a macromolecular elastic body key, in particular to a patch-type silicone elastic key without protruding pins. Background technique [0002] The conductive adhesive button industry was born in the 1980s and 1990s. Conductive monomer connectors are colloquially called keys. Whether in military products or civilian products, almost all electronic products all need to have function keys. At present, there are many keys using silica gel and elastic rubber, such as telephones, computer keyboards, remote controls, controllers, air conditioners and other electronic products containing various function keys. The current plight of the silicone keypad industry can be summarized as the lack of uniform norms and standards and the reliance on manual assembly. [0003] First of all, since the existing conductive monomer function buttons are non-standard parts, each electronic product nee...

AI Technical Summary

Problems solved by technology

Secondly, the assembly process of the existing silicone buttons mainly relies on manual work, and the production efficiency is low; generally, the silicone buttons have positioning feet and related positioning designs. Positioning and assembly, that is, manually put the positioning pin of each conductive single function button through the positioning hole of the circuit board

Relying on manual positioning and assembly results in low product production efficiency, high cost, and requires a large workplace

[0004] Based on the background of non-standard parts, although various measures to improve efficiency can be taken, such as the use of automation equipment, auxiliary packaging and other improvement methods, none of them can fundamentally solve the problems of high input costs and low production efficiency
