Abstract
A touch switch comprises a center static contact, edge static contact and an electric conduction reed, all of which are arranged in the base. An elastic rubber piece covers the upper portion of the base. A cover plate presses the skirt edge of the elastic rubber piece and is buckled and connected with the base tightly. A large through hole is formed in the center of the cover plate, the upper portion of the elastic rubber piece is exposed out of the large through hole to serve as a button, an elastic deformation inclined wall of the elastic rubber piece is in a circular bead step shape, a downward protruding pressing block is arranged inside the elastic rubber piece, the lower end of the downward protruding pressing block exceeds the lower plane of the skirt edge of the elastic rubber piece and is in pressing and touching fit with the upper surface of the electric conduction reed, and a short-stroke pressing switch structure is formed. The electric conduction reed can be pressed to conduct the switch by slightly pressing the elastic rubber piece downward, the needed stroke is short, the response is fast and sensitive, the elastic deformation inclined wall in the circular bead step shape can be fully deformed and reset in the small space, the overall size of the switch is compact, the occupied installing space is smaller, and the layout is more flexible.
Description
Technical field: the present invention relates to a kind of switching device, particularly touch-switch.
Background technology: on the electrical equipment in automobile and other field, often need to use touch-switch, the elastic rubber of common touch-switch is made into hollow circuit cylinder boss shape usually, forms handle and strain wall, by pressing, elastic rubber is out of shape to press down conductive reed, realize switch on and off.The touch-switch of this structure is in order to guarantee reliable strain and reply and have excellent handle simultaneously, the stroke of needs pressing can be longer, the space that rubber parts distortion needs is also larger, make the volume size of whole switch bigger than normal, compact not, application restriction is installed many, and pressing triggering reaction is fast not enough.
Summary of the invention: for the deficiencies in the prior art, the invention provides a kind of compact touch-switch rational in infrastructure.
The present invention includes and be arranged in center fixed contact in base and edge fixed contact, each fixed contact respectively with the pin conducting of correspondence, also conductive reed is placed with in base, the middle part of this conductive reed contacts with center fixed contact elasticity opening and closing, the corner of conductive reed contacts laminating with edge fixed contact, elastic rubber covers in the top of base, cover plate push down elastic rubber shirt rim and and base be fastened and connected airtight, this cover plate central is provided with large through-hole, large through-hole is exposed as button in the top of elastic rubber, the strain skew wall of elastic rubber adopts fillet step shape, the inside of elastic rubber is provided with lower convex in block, this lower convex lower end by block exceed elastic rubber shirt rim lower plane and and conductive reed upper surface pressing touching cooperation, form short stroke press switch structure.
Elastic rubber in the present invention slightly presses down can press conductive reed actuating switch, the stroke needed is short, reaction rapid sensitive, the strain skew wall of fillet step can abundant deformation and reply in little space, makes the overall dimensions of switch compact, install take up room less, arrange more flexible, and well airtight after cover plate and elastic rubber assemble, not by the impact of steam, dust, performance is very reliable.
The present invention is further illustrated below in conjunction with drawings and Examples.
Accompanying drawing illustrates: Fig. 1 is the main structure schematic diagram of embodiment.
Fig. 2 is the switch-turn-ON states schematic diagram of Fig. 1.
Fig. 3 is the stereogram of cover plate.
Fig. 4 is the upward view of cover plate.
Fig. 5 is the main structure schematic diagram of elastic rubber.
Fig. 6 is the stereogram of elastic rubber.
Fig. 7 is the stereogram of conductive reed.
Fig. 8 is the stereogram of base.
Embodiment: as shown in Figures 1 to 8, center fixed contact 5 and edge fixed contact 6 are arranged in base 1, and edge fixed contact 6 can have two, each fixed contact respectively with pin 7 conducting of correspondence.In base 1, be also placed with conductive reed 2, the middle part of this conductive reed 2 contacts with the opening and closing of center fixed contact 5 elasticity, and the corner of conductive reed 2 contacts laminating with edge fixed contact 6.Elastic rubber 3 covers in the top of base 1, cover plate 4 push down elastic rubber 3 shirt rim and and base 1 be fastened and connected airtight, this cover plate 4 center is provided with large through-hole 8, large through-hole 8 is exposed as button in the top of elastic rubber 3, the strain skew wall 9 of elastic rubber 3 adopts fillet step shape, the inside of elastic rubber 3 is provided with lower convex in block 10, this lower convex lower end by block 10 exceed elastic rubber 3 shirt rim lower plane and and the upper surface pressing touching of conductive reed 2 coordinate, formation short stroke press switch structure.
The shirt rim of the elastic rubber 3 in the present embodiment is provided with several location hole 11, and the lower surface of cover plate 4 is then provided with several reference column 12 corresponding matching, and both position cooperations are more accurate like this.A chimb enclosed continuously 13 is provided with in base 1 upper surface, the shirt rim correspondence of this chimb 13 and elastic rubber 3 is sealed and matched, better tightness so after mounting, conductive reed 2 and center fixed contact 5 and edge fixed contact 6 is made to be placed in the annular seal space of switch internal, water and dust is stoped to enter, in order to avoid affect the electric conductivity of switch completely.
Pin 7 is that injection moulding is entrenched in base 1, can make direct insertion and SMD two kinds of forms, and general pin 7 and corresponding fixed contact are integrative-structures, is also that the inner end portion of pin 7 is as fixed contact.The present embodiment is also provided with groove on the surface of center fixed contact 5 and edge fixed contact 6, prevents single-contact, and when conducting, electrical contact is more reliable, and dust-proof, oxidation proof properties also significantly improves.Conductive reed 2 can be designed to the series of different elastic force and different coating, can change touching operating physical force and the contact resistance of switch by changing conductive reed 2, easy to adjust.
During push switch, also namely press elastic rubber 3 top down, strain skew wall 9 elastic deformation rapidly, the lower convex of elastic rubber 3 forces the surface of pressing conductive reed 2 to be out of shape downwards by block 10, contact with center fixed contact 5 fast in the middle part of conductive reed 2, make switch conduction arrive state as shown in Figure 2.After removing the external force of pressing, strain skew wall 9 elastic recovery, elastic rubber 3 and convexly lift reset by block 10 down, conductive reed 2 also produces bounce-back under the elastic force effect of self, leave center fixed contact 5 fast, switch disconnects, and is returned to initial condition as shown in Figure 1.In make-break operation process, strain skew wall 9 can abundant deformation and reply in little space, and the pressing stroke of elastic rubber 3 is short, and reaction fast.
