Abstract

The utility model discloses a vibration switch, particularly a vibration switch which uses inertia force. The utility model comprises a spring 2, a top plate 3, a shell cover 1 and conductive pins 4, 5, wherein the inner wall of the shell cover is provided with steps which are lower than the outer wall and are used for containing the top plate and fixing the conductive pins, the shell cover is provided with a hollow cavity which can contain the spring, the conductive pins are provided with two sheet-shaped clamping sheets which are used for fixing the spring, the hollow cavity is also provided with two fixed ribs which prevent the spring from shifting and the conductive pins extend out of the shell cover along the horizontal direction of the shell cover. Because the conductive pins of the vibration switch extend out of the shell cover along the horizontal direction, the thickness is made less than a congener switch. The inner hollow cavity of the shell cover of the vibration switch is provided with the fixed ribs and the conductive pins of the clamping sheets which are used for fixing the spring and are provided with two sheet-shaped structures, therefore the spring can not be inclined or be slid out of the conductive pins.

Description

A kind of simple and easy vibroswitch

Technical field

The utility model relates to a kind of vibroswitch, particularly a kind of inertia force vibroswitch that utilizes.

Background technology

Vibroswitch is widespread usage, particularly uses spring as resilient contact, because of spring good, highly sensitive, and be widely used, utilize inertia force to make the vibroswitch vibration such as footwear light-emitting device etc., realize in the circuit conducting with close, thereby start-up circuit is made relevant action.Known traditional vibroswitch generally comprises the insulation shell assembly, spring and fixture assembly thereof, nearly all vibroswitch all uses structure like insulation shell and the spring-like, and difference is that mainly the fixture assembly is different, generally all use a wiring board and relevant hardware to fix spring as the substrate holder, housing and electric contact separation are come, solve the conducting in the circuit well and closed the not high problem of sensitivity, but also bring other problem simultaneously, because use wiring board and hardware as fixed support, just pack into then in the housing, make that so this vibroswitch is thicker, production process is more complicated also, makes production cost than higher.Patent CN2672839Y mentions a kind of simple and easy switch, wherein conductive feet 5,6 all is that vertical base plate 1b stretches out outside the insulation shell along recess 11, in application process, need like this to insert and be welded on wiring board or other objects, make the thickness of entire product produce overlaying relation, cause thickness to increase, the thin product of thickness requirement is become inapplicable, make the application of this vibroswitch limitation occur for some, when the thin products such as slippers, just contradiction has appearred such as this class switch application; Conductive feet 6 also has only a monolithic to nip the end of spring 2a in addition, as the strong point,, make spring appearance when vibration tilt or skid off this conductive feet because spring has twisting, bring the unsteadiness factor for the operate as normal of switch, the functional reliability of switch is reduced.

The utility model content

The utility model purpose is to provide a kind of simple and easy vibroswitch, and its technical problem that at first will solve is to reduce the thickness of switch, and its further technical issues that need to address are that switch reliable operation, production cost are reduced.

Simple and easy vibroswitch provided by the utility model, as Fig. 1, shown in 2, comprise spring 2, top board 3, also comprise clamshell 1 and conductive feet 4,5, the inwall of described clamshell 1 has a step 6 that is lower than outer wall, be used to hold top board 1 and fixing conductive feet 5, clamshell 1 has a cavity that can hold described spring 2, cavity also has a cavity that mates with conductive feet 4 on one side, conductive feet 4 is the intermediate plates with two laminated structures, be used for fixing described spring, cavity diapire and sidewall have two fixedly muscle that prevent spring 2 displacements, described conductive feet 4,5 welding foot stretches out outside the clamshell 1 along clamshell 1 horizontal direction, and described spring makes conductive feet 4 and 5 conductings or disconnection under the inertia force effect.

Because two conductive feet along continuous straight runs of simple and easy vibroswitch described in the utility model stretch out outside the clamshell, external product and vibroswitch are on the same horizontal plane, make them overlap by thickness, rather than stack, so the gross thickness of product is lower than similar switch, in addition because the conductive feet that the internal cavities of the clamshell tool of vibroswitch described in the utility model has fixing muscle and is used for fixing the intermediate plate with two laminated structures of spring, although spring has torsion, can not make the spring inclination yet or skid off this conductive feet, make that the vibroswitch functional reliability is very good, add simple and easy vibroswitch described in the utility model and adopt comparatively simple structure, saved the substrate holder of conventional switch, make structure simpler, production cost is lower, and range of application is more extensive simultaneously.

Below in conjunction with accompanying drawing, the utility model is described.
