Abstract
The utility model discloses a switch, particularly a push switch. The push switch with longer service life comprises a shell, fixed fins arranged on the shell, a push button installed on the shell, a slide block connected with the push button, a rocker pivot pin, a rocker moving plate using the rocker pivot pin as a pivot, and an elastic trigger part arranged on the slide block, wherein the elastic trigger part is attached to the rocker moving plate and forms a movable fit with the rocker rotor plate; and the kinematic trajectory of the rocker moving plate passes through the fixing pins and contacts the fixing pins in a beat mode. By using the beat-type contact between the rocker moving plate and the fixing pins, the friction loss between the rocker moving plate and the fixing pins is avoided, thereby maintaining good contact between the rocker moving plate and the fixing pins in the long-term use process and prolonging the service life. A spring and a steel ball trigger the rocker moving plate, thereby ensuring good contact between the rocker moving plate and the fixing pins.
Description
Technical field
The utility model relates to a kind of switch, especially a kind of push switch.
Background technology
The automobile that uses at present generally adopts sliding structure with push switch; Move by slide and the fixing relative position between the pin and to realize contacting and disconnection of switch; Thereby the break-make of control electrical appliance; The push switch of sliding structure mainly is made up of fixedly pin, shell, button in slide, spring, the end holder assembly, is connecting slide block on the slide, and slide block is connecting button.The upper and lower of button pressed, and driving that slide is upper and lower to be moved, and upwards breaks off the on-off function of realizing switch with connection downwards through slide and fixing pin.Because slide is to rely on slip to contact with fixing pin; Therefore in use just be easy to wearing and tearing; Thereby cause slide to reduce or even be difficult to contact with the contact area of fixing pin; Therefore the push switch of this structure exists shortcomings such as contact resistance is big, load capacity is little, mechanical wear is serious, working life is short, reliability is low, can't satisfy the demand of client to high-quality, high reliability, long-life switch.
The utility model content
The utility model technical problem to be solved provides a kind of push switch of longer service life.
The utility model solves the push switch that its technical problem adopted; Comprise housing, be arranged on the fixedly pin on the said housing, the slide block that is installed in the button on the said housing and links to each other with said button; Also comprise seesaw fulcrum pin, be the seesaw moving plate of fulcrum and be arranged on the elasticity trigger part on the said slide block with said seesaw fulcrum pin; Said elasticity trigger part be fitted on the said seesaw moving plate and with said seesaw moving plate movingly, thereby the movement locus of said seesaw moving plate contacts with said fixedly pin clapper-type through said fixedly pin.
Further be, said elasticity trigger part comprises spring and steel ball, and said slide block is provided with mounting groove, and said length of spring compressed is provided with in the said mounting groove, and said steel ball is arranged between said spring and the said seesaw moving plate.
Further be that said seesaw moving plate and said fixedly pin are provided with the silver alloy contact layer at the clapper-type contact point.
The beneficial effect of the utility model is: utilize the seesaw moving plate to contact with fixing pin clapper-type, avoided frictional dissipation between the two, thereby in long-term use, also can keep good contact between the two, increased useful life.Utilize spring and steel ball to touch the seesaw moving plate, spring can compress the seesaw moving plate, thereby guarantees seesaw moving plate and fixing pin maintenance excellent contact.The contact layer resistance of silver alloy is less, thereby keeps good electrical conductivity.

Parts, position and numbering among the figure: housing 1, fixedly pin 2, button 3, slide block 4, seesaw fulcrum pin 5, seesaw moving plate 6, spring 7, steel ball 8.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1; The utility model comprises housing 1, is arranged on the fixedly pin 2 on the said housing 1, the slide block 4 that is installed in the button 3 on the said housing 1 and links to each other with said button 3; Also comprise seesaw fulcrum pin 5, be the seesaw moving plate 6 of fulcrum and be arranged on the elasticity trigger part on the said slide block 4 with said seesaw fulcrum pin 5; Said elasticity trigger part be fitted on the said seesaw moving plate 6 and with said seesaw moving plate 6 movingly, thereby the movement locus of said seesaw moving plate 6 contacts with said fixedly pin 2 clapper-types through said fixedly pin 2.The elasticity trigger part can be slidingly matched with seesaw moving plate 6, and the cooperation of also can rolling utilizes spring, and elastic such as rubber can realize the spring function of elasticity trigger part.Seesaw fulcrum pin 5 is injection-moulded in the integral body that becomes parts on the housing 1 with fixing pin 2; Pack into seesaw fulcrum pin 5 and form the seesaw structures of seesaw moving plate 6 with seesaw fulcrum pin 5; Seesaw moving plate 6 connects with fixing pin Bridge 2; Elastic contact part is packed in the slide block 4 and is contacted with seesaw moving plate 6, and slide block 4 is connected to form operating body with button 3.When button 3 is pressed downwards by operating physical force; Driving slide block 4 moves down; Move down at seesaw moving plate 6 through the elastic contact part on the slide block 4, produce counter-rotating between seesaw moving plate 6 and the seesaw fulcrum pin 5, the bottom of seesaw moving plate 6 is to anticlockwise; And on fixing pin 2, carry out the connection of clapper-type, thereby realize the turn-on power loss of switch.In like manner, after button 3 lost operating physical force, the working spring in the switch can upwards promote button 3; Driving slide block 4 moves up; Move up at seesaw moving plate 6 through the elastic contact part on the slide block 4, produce counter-rotating between seesaw moving plate 6 and the seesaw fulcrum pin 5, the lower rightward rotation of seesaw moving plate 6; And leave fixedly pin 2, thereby realize the break function of switch.Can find out from said structure, seesaw moving plate 6 and fixedly not slip between the pin 2, so friction between the two is considerably less, this contact area that causes because of friction with regard to avoiding reduces, and has increased the useful life of switch.The elasticity trigger part can also compress seesaw moving plate 6 and fixing pin 2, thereby guarantees to compress the seesaw moving plate 6 and the fixing contact area of pin 2, makes the use that switch can be reliable and stable.
Concrete, as shown in Figure 2, said elasticity trigger part comprises spring 7 and steel ball 8, and said slide block 4 is provided with mounting groove, and said spring 7 compressions are provided with in the said mounting groove, and said steel ball 8 is arranged between said spring 7 and the said seesaw moving plate 6.Steel ball 8 is partially embedded in the mounting groove, and in use, button 3 promotes slide block 4 and moves up and down; Thereby steel ball 8 receives the constraint of mounting groove along with slide block 4 motions; Under the pressure effect of spring 7, steel ball 8 can promote seesaw moving plate 6 tiltings, thereby opens and closes switch.Steel ball 8 top layers can be provided with wearing layer, and spherical steel ball 8 is less with seesaw moving plate 6 contacts area, thereby can reduce friction, and reduce wear, and improve useful life.
In order to improve conductance, said seesaw moving plate 6 is provided with the silver alloy contact layer with said fixedly pin 2 at the clapper-type contact point.
