Description
Technical field
The utility model relates to a kind of switch, particularly a kind of reset switch.
Background technology
Present employed reset switch is nothing more than the switch, conductive rubber switch and the elargol thin film switch that are spring-piece type.Wherein elastic sheet switch is to be provided with the metal clips that several are the semicircle sphere, and when the user pushes this metal clips, this metal clips will contact corresponding circuit simultaneously, make circuit turn-on.Split when putting horizontal reset into when needs, need push metal clips once more.This switch is not that easily simultaneously, the conducting position contact area of switch is little when using, and occurs the situation of loose contact after long-term the use easily.
Summary of the invention
The purpose of this utility model provides a kind of reset switch, and this reset switch good stability is easy to use, and has the advantage that cost is low and applicability is strong.
The technical scheme that realizes the utility model purpose is as follows:
Reset switch, comprise housing with cavity, the housing upper surface is provided with and is communicated with described cavity opening, the lower end of one "T"-shaped button is passed in the cavity that opening extend into housing, this button comprises insulation press section and conducting rod, be provided with the conductive seat that is positioned at described conducting rod below in the cavity of described housing, be symmetrically arranged with bearing in the described cavity, the upper end of one spring is connected with the lower surface, insulation press section of button, the spring lower end is connected with bearing, the upper surface of described housing is provided with retractor device, the insulation press section of this retractor device and button near.
The upper surface of described bearing is provided with blind hole, and described spring is fixed in this blind hole.
Described conductive seat upper surface is provided with cavity, and this cavity is provided with a conducting strip, and this conducting strip lower surface is connected with a spring.
The positioning seat that described retractor device comprises guide vane end stop, compresses spring and have cavity, described guide vane end stop one end is connected with the compression spring, and the compression spring other end is fixed in the cavity of positioning seat.
The end that described guide vane end stop connects the compression spring is snug fit in the cavity of positioning seat.
Adopted such scheme, be symmetrically arranged with bearing in the described cavity, the upper end of one spring is connected with the lower surface, insulation press section of button, the spring lower end is connected with bearing, when exerted pressure in the insulation press section, the insulation press section transfers the pressure to spring, makes length of spring compressed and accumulates restoring force, and conducting rod extend in the groove of conductive seat and closely contacts with conducting strip.The upper surface of housing is provided with retractor device, the insulation press section of this retractor device and button near.The insulation press section is pressed behind bottom offset, and it is spacing to the insulation press section that the guide vane end stop of retractor device is made bottom offset at the tension force of compression spring, can prevent that like this button from automatically reseting, and guarantees the reliability and the stability of switching on.When the needs open circuit, promote the elastic force that guide vane end stop overcomes the compression spring, initial position is got back in the insulation press section under the return action power of spring, and with guide vane end stop near.Therefore, the utlity model has simple, the convenient and reliable advantage of use
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of embodiment of the present utility model.
In the accompanying drawing, 1 is housing, and 2 are the insulation press section, and 3 is conducting rod, and 4 is conductive seat, and 5 is conducting strip, and 6 is spring, and 7 is bearing, and 8 is spring, and 9 is guide vane end stop, and 10 are the compression spring, and 11 is positioning seat.
Embodiment
With reference to Fig. 1, be reset switch of the present utility model, comprise the housing 1 with cavity, the housing upper surface is provided with and is communicated with described cavity opening, the lower end of one "T"-shaped button is passed in the cavity that opening extend into housing, and this button comprises insulation press section 2 and conducting rod 3.Be provided with the conductive seat 4 that is positioned at described conducting rod below in the cavity of described housing, described conductive seat upper surface is provided with cavity, and this cavity is provided with a conducting strip 5, and this conducting strip lower surface is connected with a spring 6.The upper end that is symmetrically arranged with bearing 7, one springs in the described cavity is connected with the lower surface, insulation press section of button, and the spring lower end is connected with bearing.The upper surface of described bearing 7 is provided with blind hole, and described spring 8 is fixed in this blind hole.The upper surface of described housing 1 is provided with retractor device, the insulation press section of this retractor device and button near.Described retractor device comprises guide vane end stop 9, compression spring 10 and the positioning seat 11 with cavity, and described guide vane end stop 9 one ends are connected with compression spring 10, and compression spring 10 other ends are fixed in the cavity of positioning seat 11.The end that described guide vane end stop 9 connects compression spring 10 is snug fit in the cavity of positioning seat 11.
When need using switch of the present utility model, exerted pressure in insulation press section 2, conducting rod 3 moves downward in the groove that inserts conductive seat 4, and conducting rod 3 is closely contacted with conducting strip 5.Insulation press section 2 makes spring 8 compression and accumulates the answer energy in the process that presses down, and simultaneously, the tension force of compression spring 10 promotes the upper surface that guide vane end stop moves to insulation press section 2, and the axial location of insulation press section 2 is limited.When the needs open circuit, promote the elastic force that guide vane end stop overcomes the compression spring, initial position is got back in insulation press section 2 under the return action power of spring 8, and with guide vane end stop 9 near.
