Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, switch of the present invention, comprises pedestal 1 and arrangesCover plate 2 on pedestal 1, is provided with the first terminal 3 and the second terminal 4, the second terminals 4 in pedestal 1On be provided with stationary contact 5, pedestal 1 is stretched out respectively in one end of the first terminal 3 and the second terminal 4, also comprisesCan do the straight-line handle 6 that pushes away with respect to pedestal 1, on cover plate 2, be provided with through hole 7, push away one end of handle 6Stretch out cover plate 2 and can be along through hole 7 axially-movables through through hole 7, push away between the other end and pedestal 1 of handle 6Be connected by main spring 8, the other end of the first terminal 3 is positioned at pedestal 1 and this end and is provided with around this end and turnsMoving movable contact spring 9, is provided with the movable contact 10 matching with stationary contact 5 on movable contact spring 9, push away on handle 6 and establishBe equipped with and when handle 6 moves, promote the pushing mechanism that movable contact spring 9 rotates around the first terminal 3 ends pushing away.
In actual production, can adopt following pushing mechanism simple in structure, described in push away the interior setting of handle 6Have spring eye 11, pushing mechanism comprises the auxiliary spring 12 being embedded in spring eye 11 and is connected in auxiliary spring 12 1The push rod 13 of end, push rod 13 offsets with movable contact spring 9. In order to prevent in the time that needs disconnect single electric current during because of conductingThe excessive situation generation that causes stationary contact 5 and movable contact 10 to depart from, described movable contact spring 9 is with respect to movable contactThe other end end of point 10 forms push jack 14 after push rod 13 bendings, is provided with inclined-plane 15 on push rod 13,The end of push jack 14 is against on this inclined-plane 15.
Movable contact spring 9 with the annexation of the first terminal 3 can be, on described movable contact spring 9, is provided with groove 16,The end of the first terminal 3 is positioned at this groove 16 and offsets with movable contact spring 9. This structure easy accessibility.
Also can be that the middle part of described movable contact spring 9 is hinged with the end of the first terminal 3.
In described pedestal 1, be also provided with circuit board 17 and the 3rd terminal 18, the three being connected with circuit board 17Pedestal 1 is stretched out in one end of terminal 18, and the first terminal 3 is connected with circuit board 17 by wire 19.
On described circuit board 17, be provided with controllable silicon 20 and three carbon film bars---the first carbon film bar 21, secondCarbon film articles 22 and the 3rd carbon film articles 23, wherein the first carbon film bar 21 and the second carbon film bar 22 are positioned at a straight line,Parallel and the projection of the 3rd carbon film articles 23 and the first carbon film articles 21 covers the first carbon film articles 21 and the second carbon film articles 22,Push away on handle 6 reed 25 be set, on reed 25, have two feelers---main feeler 26 and secondary feeler 27, secondary touchingAngle 27 contacts with the first carbon film bar 21, the second carbon film bar 22, and main feeler 26 and the 3rd carbon film articles 23 contacts.
On described circuit board 17, be provided with the required controllable silicon of circuit 28, in order to reduce the temperature of controllable silicon 28,On described controllable silicon 28, be provided with fin 24.
Operation principle of the present invention is: as shown in Figure 3, push away handle 6 to pressing in pedestal 1, push away handle 6 and drive topBar 13 moves down, in the time that push rod 13 moves to the below, end that the first terminal 3 contacts with movable contact spring 9,Under the effect of auxiliary spring 12 and push rod 13, movable contact spring 9 rotates around the end of the first terminal 3, moving like thisContact 10 just contacts with stationary contact 5, whole switch conduction. And in the time that needs disconnect, stop executing pushing away handle 6Plus-pressure, pushes away handle 6 and resets under the effect of main spring 8, and push rod 13 is the groove 16 of process movable contact spring 9After move up, and with the upper end in contact of movable contact spring 9, if now electric current is very large, the effect of auxiliary spring 12Power cannot overcome the suction between stationary contact 5 and movable contact 10, so outwards pulls out and pushes away handle 6, makes push rod 13Inclined-plane 15 push jack 14 on movable contact spring 9 is applied to a component to the right, execute to movable contact spring 9 upper endsAdd an active force to the right, because the first terminal 3 is to be against in the groove 16 of movable contact spring 9, profit soBy the principle of seesaw, the movable contact 10 that is positioned at movable contact spring 9 lower ends is just bound to depart from stationary contact 5, fromAnd the normal use of guarantee switch ensures its security. Certainly when being used, reality can use elastic forceEnough large main springs 8, unclamping while pushing away handle 6, just can ensure that push rod 13 is bound to movable contact spring 9 like thisUpper end produce active force, thereby ensure that the movable contact 10 on movable contact spring 9 is bound to depart from stationary contact 5.
