Description
Technical field
The utility model relates to a kind of sensitive switch, relates 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 conventionally 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, switches simultaneously, conventionally a plurality of sensitive switches need to be combined to 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 signal disorderly; 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 existing in prior art, the utility model 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 utility model 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 described switching mechanism consists of the elastic contact blade that is fixed on inlet wire plate and the outlet board in described pedestal and be fixed on described inlet wire plate; Switching mechanism is four groups, described wink actuation mechanism by being fixed on support, one end in pedestal, being fixed on driving member, one end that the other end on this support is fixed with spring base and being fixed on elastic overturning sheet, another spring base that is fixed on this elastic overturning sheet other end of being the shape of falling Ω on support, being fixed on stage clip between two spring bases, being located in pedestal and upper end contacts the top board that lower end and each elastic contact blade keep in touch and forms with elastic overturning sheet.
There is the second outlet board being fixed in pedestal the top of elastic contact blade; Pedestal is coated by metal shell.
Compared with the prior art, the utility model is owing to having adopted technique scheme, utilize the elastic force of stage clip to realize distortion or the reset of elastic overturning sheet, thereby by oppressing or unclamping top board and realize each elastic contact blade and synchronize contact or disconnect with outlet board, finally reach the object 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 coated metal shell of pedestal, so the utility model also has the effect of shielding electromagnetism and anti-irradiation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
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 utility model is described in further detail:
As shown in Figure 1: in the pedestal 3 of housing shape, have wink actuation mechanism and four groups of switching mechanisms, described in each, switching mechanism is by the inlet wire plate 6 and the outlet board 8 that are fixed in pedestal 3, be fixed on and on inlet wire plate 6, be the elastic contact blade 5 that bends font and form, described wink, actuation mechanism was by the support 1 that is fixed on each switching mechanism top, one end is fixed on the driving member 12 that is L shape structure on this support, 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, is respectively 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 four circuit, synchronously connects.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 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 and by top board 7 jack-up, synchronously disconnects thereby realize four circuit with corresponding outlet board 8.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.
