Each switching mechanism is composed of a wire inlet board, a wire outlet board and an elastic contactor, wherein the wire inlet board and the wire outlet board are fixed in the base, the elastic contactor is fixed to the wire inlet board, and four sets of switching mechanisms exist. The twinkling mechanism is composed of a support (1) fixed in the base (3), a transmission part (12), an elastic turn-over part (4), a pressure spring (11) and a top plate (7), wherein the transmission part (12) and the elastic turn-over part (4) are respectively fixed to the support through suspension arms, the two ends of the pressure spring (11) are connected with the transmission part (12) and the elastic turn-over part (4) respectively, the top plate (7) is arranged in the base, the upper end of the top plate (7) makes contact with the elastic turn-over part (4), and the lower end of the top plate (7) makes contact with all the elastic contactors. The combined microswitch is high in repeatability, good in electromagnetic shielding and irradiation resistance and capable of controlling four circuits to be simultaneously connected and disconnected at the same time.
Description
Technical field
The present invention relates to a kind of sensitive switch, relate in particular to a kind of composite type sensitive switch.
Background technology
Sensitive switch is called again sensitive switch, because it is closed or disconnect instantaneous conversion speed, is exceedingly fast, and therefore in automatic control circuit, is commonly used to commutation circuit; It usually by pedestal, stretch into handle in this pedestal, be located in this pedestal wink actuation mechanism and switching mechanism form.A sensitive switch generally can only be controlled the break-make of a circuit, if will realize, a plurality of circuit switch simultaneously, usually a plurality of sensitive switches need to be combined to the associating use; Not only cumbersome, and be difficult to guarantee a plurality of sensitive switch synchronization actions.When making for signal controlling, easily cause control signal can not synchronously be switched on or switched off, cause the signal disorder; When controlling for a plurality of circuit, can cause the instantaneous phase shortage of power consumption equipment or short circuit, cause damage.
Summary of the invention
For the above-mentioned defect existed in prior art, the present invention aims to provide a kind of simple in structure, good reliability, can control the composite type sensitive switch of four synchronous break-makes of circuit simultaneously.
To achieve these goals, the present invention is by the following technical solutions: it comprises that inside is provided with wink actuation mechanism and the pedestal of switching mechanism, stretch into the handle in this pedestal, and inlet wire plate and the outlet board of described switching mechanism in being fixed on described pedestal and the elastic contact blade be fixed on described inlet wire plate form; Switching mechanism is four groups, and support, the end of described wink actuation mechanism in being fixed on pedestal is fixed on driving member, an end that the other end on this support is fixed with spring base and is fixed on support elastic overturning sheet, another spring base that is fixed on this elastic overturning sheet other end of being the shape of falling Ω, is fixed on stage clip between two spring bases, is located in pedestal and upper end contacts the top board that lower end and each elastic contact blade keep in touch and forms with the elastic overturning sheet.
There is the second outlet board be fixed in pedestal the top of elastic contact blade; Pedestal is coated by metal shell.
Compared with the prior art, the present invention is owing to having adopted technique scheme, utilize the elastic force of stage clip realize the distortion of elastic overturning sheet or reset, thereby by compressing or unclamp top board and realize that each elastic contact blade synchronize with outlet board and contact or disconnection, finally reach the purpose of four circuit of Synchronization Control; There is the advantages such as repeatable accuracy is high, good reliability.In addition, owing to having adopted the metal shell that pedestal is coated, so the present invention also has the effect of shielding electromagnetism and anti-irradiation.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: support 1, metal shell 2, pedestal 3, elastic overturning sheet 4, elastic contact blade 5, inlet wire plate 6, top board 7, outlet board 8, the second outlet board 9, spring base 10, stage clip 11, driving member 12, pressure handle 13.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described:
As shown in Figure 1: wink actuation mechanism and four groups of switching mechanisms is arranged in the pedestal 3 of housing shape, inlet wire plate 6 and the outlet board 8 of each described switching mechanism in being fixed on pedestal 3, be fixed on inlet wire plate 6 and be elastic contact blade 5 formations of bending font, described wink, actuation mechanism was by the support 1 that is fixed on each switching mechanism top, one end is fixed on this support the driving member 12 that is L shape structure, be fixed on the free-ended spring base 10 of this driving member, one end is fixed on the elastic overturning sheet 4 that is the shape of falling Ω on support 1, be fixed on free-ended another spring base 10 of this elastic overturning sheet, be connected to the stage clip 11 between two spring bases 10, be located in pedestal 3 and upper end contacts the top board 7 that lower end and each elastic contact blade 5 keep in touch and forms with elastic overturning sheet 4, the pressure handle 13 that stretches into pedestal 3 keeps in touch with driving member 12.
In order to guarantee that each elastic contact blade 5 can contact with top board 7 simultaneously, respectively is fixed with the second outlet board 9 of equal height above each elastic contact blade 5 is free-ended.For safety, also in order to improve shielding and Radiation hardness, on pedestal 3 surfaces, be coated with metal shell 2 simultaneously.
Operation principle: during normal condition, elastic overturning sheet 4 is the shape of falling Ω structure; The elastic force of stage clip 11 promotes top board 7 downwards by this elastic overturning sheet, makes this top board oppress each elastic contact blade 5 and synchronously contacts with corresponding outlet board 8, thereby realize that four circuit synchronously connect.When pressing pressure handle 13, the reaction force that is subject to top board 7 along with elastic overturning sheet 4 increases gradually, and elastic overturning sheet 4 elastic deformation amounts are also increasing gradually; When the elastic deformation amount reaches critical value, upwards overturn immediately and form Ω shape structure, the instantaneous disengaging top board 7 of elastic overturning sheet 4 in the stage casing of this elastic overturning sheet; So each elastic contact blade 5 synchronously disengages with corresponding outlet board 8 by top board 7 jack-up, thereby realize that four circuit synchronously disconnect.When unclamping pressure handle 13, elastic overturning sheet 4 reverts to normal condition under the effect of stage clip 11 elastic force, so each circuit can synchronously be switched to on-state again.
