Abstract
The utility model discloses a five-loop dustproof touch switch. A cover plate is connected with a base in an inverted manner. A dustproof film is connected between the cover plate and the base. A cavity is formed between the cover plate and the base. Five groups of terminals are integrally molded on the base in an injection manner. A part of each terminal is disposed in the base, and the other part is exposed in the cavity. Springs are five connected arc-shaped springs. The five arc-shaped springs are arranged in a plum blossom structure. The springs are disposed in the cavity. The five arc-shaped springs are respectively corresponding to the five terminals. A through-hole is disposed in the middle of the cover plate. A side pressing button is positioned by the through-hole, wherein the upper part of the side pressing button is exposed in air, and the lower part is disposed in the cavity. A square hole is disposed in the middle of the side pressing button. A main button is positioned by the square hole. The switch is a five-loop touch switch which is simple in structure and compact in volume, and realizes menu selection of an electronic product. Direction control is completed by a switch and the switch has a dustproof function.
Description
Technical field
The utility model relates to a kind of dust-proof switch, relates in particular to a kind of five loop Dustproof soft-touch switchs.
Background technology
This class touch-switch is mostly single loop, double loop at present, mainly by cover plate, button, shell fragment and base, formed, multiplexly in electronic products such as mobile phone, digital camera, game machine, MP3, printer, remote controllers, usually adopt button pressed downwards, force the shell fragment distortion to connect circuit with termination contact, after removing pressure, shell fragment restores to the original state, open circuit.
The utility model content
The utility model purpose is exactly in order to make up the defect of prior art, and a kind of five loop Dustproof soft-touch switchs are provided.
The utility model is achieved through the following technical solutions:
a kind of five loop Dustproof soft-touch switchs, include main button, the side pressure button, cover plate, dustproof membrane, shell fragment, base and five groups of terminals, described cover plate is connected with the base back-off, described dustproof membrane is connected between cover plate and base, between cover plate and base, form cavity, described five groups of terminal integral molded plastics are on base, the part of terminal is positioned at base inside, another part is exposed in cavity, described shell fragment is the arc spring lamination of five disjunctors, five arc spring laminations are the plum blossom structural configuration, shell fragment is arranged in cavity, five respectively corresponding described five terminals of arc spring lamination, in the middle of described cover plate, have through hole, described side pressure button is located by through hole, wherein the top of side pressure button is exposed in air, bottom is in cavity, centre at the side pressure button has square hole, described main button is located by square hole, the top of main button is exposed in air, arc spring lamination in the middle of being positioned at is corresponding with main button, be positioned at four projections of the respectively corresponding side pressure button of four arc spring laminations below of periphery.
Described shell fragment adopts the silver-plated formation of beryllium-bronze, has both extended fatigue life, has guaranteed again the reliability of energising.
Described base adopts high-temperature resistance plastice to form, and meets the requirement of touch-switch SMT reflow soldering.
What described dustproof membrane adopted is cushion compound, is placed between cover plate and base, adopts interference fit, stops steam and dust to enter switch inside.
Operation principle of the present utility model is: exerted pressure in main button front, shell fragment and terminal middle part are connected, and form a loop.Main button is applied to lateral pressure, and main button drives the side pressure button and tilts, shell fragment and the position connection of terminal periphery, and all around totally four kinds of side pressure modes, can form four loops.Any mode of pressing, after removing external force, the shell fragment state that affranchises, loop disconnects.
The utility model has the advantages that: the utility model is a kind of five loop touch-switchs of simple in structure, volume compact, realizes the electronic product menu setecting, and direction is controlled by a switch and completed and have a dust reduction capability.
