Description
Technical field
The utility model relates to a kind of composite type interlock sensitive switch, relates in particular to the asynchronous interlock sensitive switch of a kind of composite type.
Background technology
Sensitive switch is called again sensitive switch, and it is closed or disconnect instantaneous conversion speed and be exceedingly fast, and is usually used for the switching of commutation circuit in automatic control circuit.A sensitive switch generally can only be controlled a circuit, if will realize a plurality of circuit, switches, and normally a plurality of sensitive switches is combined and combines use (if application number is that " 200920125278.6 ", name are called " combined type synchronous linkage microswitch "); Two unit-combination type sensitive switches by two sensitive switches form, for switching a kind of interlock sensitive switch of two circuit switchings.
At present, two unit-combination type fine motions mostly are synchronous linked switch; It is to adopt double-pole to move simultaneously, and the mode that simultaneously triggers commutation is controlled the switching of two circuit.Therefore when having sequence requirement, the switching of two circuit can not be suitable for.In addition, when switch hold actuation mechanism because mechanical wear causes stroke to change or the environmental condition such as Yin Wendu, humidity, air pressure, vibratory impulse changes while causing stroke to change, may cause the action sequence of two switch units to put upside down, cause controlling and get muddled.
Summary of the invention
For the above-mentioned defect existing in prior art, the utility model aims to provide a kind of asynchronous interlock sensitive switch of two unit-combination types of action chronologically.
To achieve these goals, the utility model is by the following technical solutions: it comprise be provided with button housing, be fixed on two groups of connector assemblies on this housing, be arranged in the moving changement of two-stage wink of this housing, described connector assembly consists of common terminal and two binding posts that are reverse U shape, first order wink, moving changement was by the first linkage board being connected with button, the insulating base being flexibly connected with this first linkage board by being located at the chute at top, be movably connected in respectively the first movable contact spring of the first linkage board both sides, be separately fixed on the first linkage board and by the first extension spring of each the first movable contact spring tension and form, second level wink, moving changement was by the second linkage board being inserted in insulating base bottom slot, be movably connected in respectively the second movable contact spring of these the second linkage board both sides, be separately fixed on the second linkage board and by the second extension spring of each the second movable contact spring tension, be fixed in housing and the spring that the second linkage board is held out against formation.
There is respectively V-shaped groove the both sides of the first linkage board and the second linkage board, and the first movable contact spring and the second movable contact spring are positioned respectively in corresponding V-shaped groove; The top of the second linkage board is fixed with adjustment pad.
Compared with the prior art, the utility model is owing to having adopted technique scheme, utilize with the first order wink insulating base that is flexibly connected of moving changement promote to move to mechanism kinematic in second level wink, so when the first linkage board moves downward, the commutation of first overturning of two blocks of first movable contact springs; When the first linkage board continues to move downward one section of idle stroke and while touching bottom chute, just promotes the second linkage board and move downward and trigger two the second movable contact springs upset commutations, thereby realize two unit, switch chronologically.The utlity model has simple in structure, response rapidly, contact the advantages such as reliable.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: the first extension spring 1, button 2, the first linkage board 3, the first movable contact spring 4, binding post 5, housing 6, the second extension spring 7, the second linkage board 8, spring 9, adjustment pad 10, insulating base 11, the second movable contact spring 12, common terminal 13, chute 14.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Figure 1: button 2 is located on housing 6, in this housing, be fixed with outwardly directed two groups of connector assemblies; Described in each, connector assembly forms by being positioned at two binding posts 5 that housing 6 left sides are common terminal 13 of reverse U shape structure and are positioned at housing 6 right sides.In housing 6, there is two-stage wink to move changement, wherein, first order wink, moving changement was by the first linkage board 3 being connected with button 2, the insulating base 11 being flexibly connected with this first linkage board by being located at the chute 14 at top, be positioned at the first linkage board 3 both sides and be flexibly connected with it respectively two blocks of first movable contact springs 4, be separately fixed on the first linkage board 3 and by two of each the first movable contact spring 4 tensions the first extension springs 1 and form, second level wink, moving changement was by the second linkage board 8 being inserted in insulating base 11 bottom slots, two blocks of second movable contact springs 12 that are positioned at these the second linkage board both sides and are flexibly connected with it respectively, be separately fixed on the second linkage board 8 and by two the second extension springs 7 of each the second movable contact spring 12 tensions, be fixed in housing 6 and by the second linkage board 8 and hold out against again spring 9 formations in described slot.
For easy to process, simultaneously also in order to improve handoff response sensitivity, the first linkage board 3 adopts following structure with the relation that is flexibly connected and the second linkage board 8 between the first movable contact spring 4 with the relation that is flexibly connected between the second movable contact spring 12: the both sides of the first linkage board 3 and the second linkage board 8 all have V-shaped groove, and the first movable contact spring 4 and the second movable contact spring 12 are positioned respectively in described V-shaped groove; The first movable contact spring 4, the second movable contact spring 12 are cutting edge shape structure with the contact jaw of V-shaped groove.
For the ease of regulating the flip-flop transition between the first movable contact spring 4, the second movable contact spring 12, at the top of the second linkage board 8, be fixed with and adjust pad 10.
Operation principle: when press push button 2, the first linkage board 3 just can drive the first movable contact spring 4 to move down, the first extension spring 1 stretcher strain; When the first linkage board 3 moves to commutation during critical point, the elastic energy abrupt release of the first extension spring 1 and trigger the first linkage board 3 upset commutations, thus realize being switched on or switched off of that group connector assembly above.Continue push button 2, the first linkage boards 3 to cover the idle stroke of chute 14 and while touching this chute bottom, just can drive the second movable contact springs 12 move down by insulating base 11, the second linkage board 8; When this second movable contact spring moves to commutation during critical point, the elastic energy abrupt release of the second extension spring 7 and trigger the second linkage board 12 upset commutations, thus realize being switched on or switched off of that group connector assembly below.Two switch elements can be realized commutation sequentially.
