Abstract
The utility model discloses a dustproof key switch, include the elastomer, lead core, button upper cover and silica gel shield, the elastomer is connected with the pedestal, the front and back both sides of leading the core are equipped with movable contact spring and still respectively, lead the core and pass through the round hole cover in the outside of elastomer, and be connected with the pedestal, the button upper cover is connected with the pedestal, and the key core of leading the core wears out the round hole of button upper cover, silica gel shield and button cover connection, it is dull and stereotyped that the lower part of silica gel shield is silica gel, and upper portion is the silica gel lid, the middle part of silica gel lid is equipped with the through -hole, the through -hole is worn out to the key core, and the joint gap department of key core and through -hole is equipped with the dustproof cap. Because the silica gel shield has elasticity for the silica gel shield can prevent very tiny dust, and the through -hole at the silica gel shield is equipped with the dustproof cap with the upper portion key core joint line crack department that leads the core moreover, can prevent that the dust from carrying out the inside of switch, avoids causing the inside contact failure of switch, does not influence moreover and feels.
Description
Technical field
The utility model belongs to switching technique field, is specifically related to a kind of dust-proof key switch.
Background technology
Switch refers to that one can make open circuit, makes current interruptions or make it flow to the electronic component of other circuit.Current switch has many kinds, such as delay switch, audio-switch and optoelectronic switch etc., and key switch is one wherein.Current key switching structure more complicated, assembling comparatively bothers, and is unfavorable for enhancing productivity, and falls into the electronic component loose contact that dust causes inside through the gap place that is everlasting, and causes switch not use normally.
Utility model content
The purpose of this utility model is to provide a kind of dust-proof key switch, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of dust-proof key switch, comprise elastomer, lead core, button upper cover and silica gel dust cap, described elastomer is connected with pedestal, described both sides, front and back of leading core are respectively equipped with movable contact spring and still, describedly lead core by circle hole sleeve in elastomeric outside, and be connected with pedestal, described button upper cover is connected with pedestal, and the key core of leading core passes the circular hole of button upper cover, described silica gel dust cap is connected with button upper cover, the bottom of described silica gel dust cap is silica gel plate, top is silica gel lid, the middle part of described silica gel lid is provided with through hole, described key core passes through hole, and the joint gap place of key core and through hole is provided with dust cap.
Preferably, described key core upper surface is provided with cruciform groove.
Technique effect of the present utility model and advantage: this dust-proof key switch, structure is simple, reasonable in design, and assembling is comparatively simple, can enhance productivity greatly; Because silica gel dust cap has elasticity, make silica gel dust cap can prevent very tiny dust, and be connected gap place at the through hole of silica gel dust cap with the top key core of leading core and be provided with dust cap, can prevent dust from carrying out the inside of switch, avoid causing switch internal loose contact, and do not affect feel.
