Embodiment
Fig. 1 and Fig. 2 are respectively the cutaway view and the exploded perspective views of the waterproof touch-switch in the embodiment of the present invention.
Automatic compensation sealing type waterproof touch-switch of the present invention; Possess: the box-shaped bottom base 1 of insulation plastic cement system is formed with the recess of top opening, is provided with plane step 1A in the recess upper surface, is provided with boss 1B in upper surface, recess angle; Be provided with cylinder salient point C1 in the boss upper surface; Admittedly put in the recess bottom surface of bottom base 1 exposing inside thereof fixed contact 3A and the outside and to touch 2A surely, 2B, and make it fixing through embedding injection molded.Inboard fixed contact 3A is set at the central authorities of bottom surface, outside fixed contact 2A, and 2B is set at the lateral surface of bottom surface.Outside fixed contact 2A, 2B and inboard fixed contact 3A are independent separately in electric property, and inboard fixed contact 3A links to each other from the outward extending external circuit-connecting terminal 3 of the sidewall 1A of bottom base 1.Outside fixed contact 2A, 2B links to each other from the outward extending external circuit-connecting terminal 2 of sidewall 1A.
Dome-shaped metal spring leaf 4 is made up of electric conductivity better elastic thin plate.The round outer circumference end of metal spring leaf 4 is placed on outside fixed contact 2A, and above the 2B, the circular arch shape end face of the lower surface of metal spring leaf 4 and inboard fixed contact 3A leave relative with gap.
By the button 6 that the insulation plastic cement constitutes, its structure is made up of the protuberance 6B of cylinder 6A and cylinder 6A feather edge.Cylinder 6A can run through self-locking holddown plate 7 central parts perforation circular hole 7A up and downly to be extended upward and gives prominence to; Cylinder 6B can insert sealing clamp 5 up and downly and connect in the circular hole 5A; The upper surface that is provided with center protuberance 6C and compound seal diaphragm 8 in the bottom surface of cylinder 6B contacts.
The self-locking holddown plate covering 7 that is made up of the metal stainless sheet steel is installed in pedestal (1) and sealing clamp 5 upper surfaces; And be formed with the perforation circular hole 7A that central part connects; Its perforation circular hole circumferential flange 7B of portion complete cycle is tubular and extends upward; The peripheral edge portion upper surface that self-locking holddown plate circumferential edges central part is provided with the outstanding domed of symmetrical downward-sloping extension prominent some 7C and sealing clamp 5 compresses and contacts, and the corner edge portion of described self-locking holddown plate 7 is provided with on the projection that perforation circular hole 7D is buckled in pedestal 1 C1 and damages by pressure fixing.Under the state that is not pressed, button 6 utilizes in the spill bottom base 1 the upwards tension force of dome-shaped metal spring leaf 4 to make button 6 can not produce to rock.
When pushing the cylinder end face 6A that is used to the button 6 of 7A protrusion in the logical circular hole from the central part of self-locking holddown plate 7, button 6 can be used to through hole 7A and fixed motion downwards.The protuberance 6C of the cylinder 6A bottom surface of button 6 is contacting the end face central part of compound seal diaphragm 8.When button 6 was pushed downwards, the protuberance 6C of button 6 cylinder 6A bottom surfaces was compressing sealed thin diaphragm 8 and circular arch shape metal spring leaf 4.The lower surface circle central part of metal spring leaf 4 contacts with inboard fixed contact 3A, and the solid point in the outside touches 2A surely like this, and 2B is electric property ground with inboard fixed contact 3A through metal spring leaf and is connected, thus push switch energising becoming out state.
When releasing was applied to the pressing force on the button 6, whole upwards jack-up moved to the original position that is provided with under the resilient force that button 6 produces at metal spring leaf 4 recovery arcuations.Metal spring leaf 4 popped up with inboard fixed contact 3A along with recovering arch shape and separated this moment, outside fixed contact 2A, and 2B and inboard fixed contact 3A are cut off by electric property ground, thus push switch becomes off status.
As being provided with compound seal diaphragm 8 between the recess opening of Fig. 1 bottom base 1 shown in Figure 2 and the sealing clamp; Between the recess opening of bottom base 1 and boss, leave plane step 1A; 8 coverings of compound seal diaphragm stick on bottom base 1 plane step 1A and go up and contacting metal reed 4 end faces; Sealing clamp 5 is buckled in the boss 1B of bottom base 1; The perforation circular hole 7D of the corner edge portion of self-locking holddown plate 7 is buckled on the projection of bottom base 1 fixing, and utilizes its circumferential edges central part to be provided with the prominent point of the outstanding domed of a symmetrical downward-sloping extension 7C and exert pressure to the sealing clamp 5 of lower surface, impels that the leg-of-mutton flange part 5B of circumference compresses compound seal diaphragm 8 between perforation circular hole 5A and the outward flange of sealing clamp 5 lower surfaces; Make the recess plane of the opening step 1A formation of compound seal diaphragm 8 and bottom base 1 close close like this; If this waterproof touch-switch is in long-term the use, owing to can making to produce between self-locking holddown plate 7 and the bottom base 1 boss 1B upper surface, the reasons such as stress of expanding with heat and contract with cold or in assembling process, produce become flexible, form the slit; But; Have strong elastic owing to be arranged on the prominent point of the outstanding domed of the downward-sloping extension of self-locking holddown plate 7 a circumferential edges central parts symmetries 7C, and the prominent point of a domed 7C is forced compression when mounted, that is to say; The prominent point of the domed of self-locking holddown plate 7 circumferential edges central parts 7C is symmetrical downward-sloping bending; If self-locking holddown plate 7 is loosening with the generation of pedestal 1 boss 1B upper surface, the prominent point of domed 7C can discharge the elasticity that is forced compression automatically, continues compressing sealing clamp 5 to compress downwards; Sealing clamp 5 has obtained constant tension force like this, makes the junction surface of recess opening and the compound seal diaphragm 8 of bottom base 1 reach the purpose of permanent seal.
