Now below referring to each description of drawings push switch of the present invention.
Earlier referring to Fig. 1.There is shown an embodiment of push switch of the present invention.Shown push switch has a horizontal U font spring element A, and this spring element comprises top 1, flexed portion 2 and lower part 3, and its lower middle portion 3 is divided into upper contact part 3a and lower contact part 3b, and lower contact part 3b is longer than upper contact part 3a.
Push switch has a support B, and support B comprises upper plate 4a, horizontal U font part 4b and lower plate 4c, and is equipped with back shaft 5.Upper plate 4a is located at the end of support B, has a pressing piece 4, and the effect of pressing piece 4 is, pushes support B when external force affacts on it, makes support B around back shaft 5 swings.Upper plate 4a, horizontal U font part 4b and lower plate 4c three inner surface separately are formed with horizontal U font fitting recess usually or recess 6 extends around back shaft 5.Laterally U font spring element A is contained in the assembling recess 6 of support B, inwardly affact simultaneously top 1 and lower part 3(or upper and lower contact part 3a and the 3b of spring element A), thus make support B and the horizontal U font spring element A work that cooperatively interacts formation contact spring element C.Contact spring element C is supported on the shell D by back shaft 5 swingably, making lower contact part 3b be pressed in first or fixed contact 7b simultaneously upward contacts with this fixed contact deflection, and the upper plate 4a that makes support B hits on a brake component 14, makes support B stop swing upwards because of the resilience force of spring element.Upper contact part 3a is placed in second or another fixed contact 7a top, and 7a is spaced a distance with fixed contact.
Laterally U font spring element A can make the sort of form shown in Fig. 5 a to 5d.More particularly, the U that generally represents with A1 in Fig. 5 a to 5d pacifies in the shape spring element, is formed with U font slit 3c on the lower part 3, thereby makes the upper contact part 3a of the core formation strip of lower part 3.
Another kind of way is that U font spring element A also can make the sort of form as Fig. 6 a to 6d.In horizontal U font spring element A2, horizontal U font spring element member a1 and horizontal U font spring element member a2 superpose fixing each other, thereby make upper contact part 3a be placed in lower contact part 3b top, constitute horizontal U font spring element A2.The end of lower part 3 promptly in spring element member a1 as upper contact part 3a, spring element member a2 is longer than spring element member a1, the end of lower part 3 promptly in spring element member a2 as lower contact part 3b.
The pressing piece 4 that is located at support B upper plate 4a end can be got any suitable form, as long as external force can be pushed support B when being applied to it, support B is got final product around back shaft 5 swings.For example, thus pressing piece 4 can be provided in a side of upper plate 4a terminal with upper plate 4a form the pressing piece 4 that an integral body can slave plate 4a end projects upwards ', as shown in Fig. 1 a.Thereby not so also can be located at independently that upper plate 4a goes up can be from the outstanding button of upper plate 4a, shown in Figure 1B.
Referring now to Fig. 2 and Fig. 3 a to 3c,, there is shown another embodiment of push switch of the present invention, wherein contact spring element c is configured in and makes among the small-sized shell D.More particularly, shell D has a housing 8, is equipped with fixed contact 7a and 7b on the interior bottom surface of housing 8.Terminal 7a ' and the 7b ' of fixed contact 7a and 7b protrude respectively outside the housing 8.Shell D also has a top board 9, has a slit 10 on the top board 9, press element 4 ' promptly insert by this slit.In addition, housing 8 is opposite each other to have side plate 11 to be provided with recess 12, and the two ends of back shaft 5 promptly are contained in this recess.In the shell D that so constitutes, contact spring element C disposes to such an extent that make it form such layout: back shaft 5 is supported in the recess 12, press element 4 ' protrude upward outside the slit 10, lower contact part 3b is pressed in fixed contact 7b and upward contacts with fixed contact 7b, upper contact part 3a then is placed in fixed contact 7a top, apart from fixed contact 7a predetermined distance d.At this moment just with shell D opposed side plate on the assembly parts 13a of the projection that forms firmly be fixed among the hole 9b that downward extension board 9a is located at top board 9 two ends, thus top board 9 firmly is fixed on the shell D.So cooperate the top board 9 that is installed on the shell D to play brake component 14,, and prevent that contact spring element D from throwing off from shell D for upwards swinging that receiving tray B produces because of lower contact part 3b contacts with fixed contact 7b pressing in shell D rear surface.
The following describes the working condition of the push switch shown in the foregoing description now.
Pressing force is added to the contact spring element C that is contained in shell D downwards, when stretching out the outer press element 4 of top board 9 slits 10, starting contact spring element, thus top 1 is pressed on the lower part 3.For embodiment in, contact spring element C is supported on the back shaft 5 by flexed portion 2 swingably, thereby the pressing force that is added to press element 4 is worked, and makes the end of lower part 3 or upper and lower contact part 3a and 3b swing.This impels lower part 3b that deflection contacts with fixed contact 7b pressing further toward pressing down, thereby it is predetermined apart from d that upper contact part 3b can be reduced, and then makes and self further contact with fixed contact 7a pressing, makes switch connection.
Said above, the pressing force that affacts on the press element 4 makes the end of lower part 3 swing downwards, upper contact part contact with the pressing of lower contact part, thus can slightly slip on fixed contact 7a and 7b when making lower contact part 3b keep pressing to contact with fixed contact 7a and 7b respectively with upper contact part 3a.
So, when removing pressing force, the top and the bottom 1 of spring element and 3 borrow resilience force to get back to original position, and the lower contact part 3b of lower part 3 turns back to original position, keep simultaneously contacting with fixed contact 7b pressing, thereby make the upper contact part 3a predetermined distance d that can move up, switch is disconnected.
Can see that from above-described in push switch of the present invention, the contact spring element is to make top and the bottom keep compressing formation simultaneously in the recess by the accurate support of making of plastic resin that horizontal U font spring element is packed into.This structure can effectively prevent horizontal U font spring element distortion, because the whole basically length of spring element all is fixed on the inner surface of support, thereby makes support can accurately regulate the upper and lower contact part of stretching out from support.Particularly keep the upper contact part of unfettered state all the more so at the switch off period.Therefore, the present invention partly can evenly stretch out upper and lower contact and can not scatter because of push switch is different.
More particularly, laterally therefore U font spring element itself causes the reason of scattering to depend primarily on the structure of spring element by metal leaf springs compacting or crooked making.Yet horizontal U font spring element can be eliminated the phenomenon of scattering that produces because of U font spring element for above-mentioned reasons during the mounted contacts spring element in the support of packing into.
This show when making push switch of the present invention since with the contact spring arrangements of components in shell, thereby lower contact part deflection ground is contacted with a fixed contact pressing with constant active force, and the spacing d between upper contact part and another fixed contact part is remained unchanged, and whichsoever push switch is all the same.Therefore, be noted that the switch performance of this push switch is satisfactory, the accuracy height, this is because pressing piece guarantees to make upper contact partly to move down predetermined distance d, thereby really contacts with a fixed contact, and push switch is connected.
In addition, push switch of the present invention is that body plan must make leaf spring material be bent into and be equipped with the horizontal U font spring element integral installation of upper and lower contact part in the support that is equipped with pressing piece, back shaft and recess, thereby form the contact spring element, the contact spring element is packed into is equipped with in the shell of fixed contact then.Therefore, this push switch has structurally been simplified, and fully solid, and cost reduces, suitable producing by batch.In addition, laterally U font spring element can adopt the sheet spring by small-sized accurate processing mass production, and support and shell can be produced by batch with plastic resin automatically with the miniature precision method of molding, but therefore push switch high accuracy miniaturization mass production of the present invention.In addition, push switch of the present invention has quite long useful life, and switch performance is good.
Have again, push switch of the present invention is made to such an extent that make the contact spring element be supported on the back shaft swingably, this structure function can make the end of lower part or upper and lower contact part to lower swing to the pressing force of pressing piece, thereby guarantee the deflection of lower contact pressurized, the upper contact part contacts with the accurate pressing of fixed contact.In addition, this can also make the end of each contact part slide on fixed contact, contacts with the fixed contact pressing simultaneously, thereby the contact can the oneself be cleared up, and then guarantee that switch performance is satisfactory.
