Description
Technical field
The present invention relates to a kind of microswitch, more particularly, to a kind of combination type microswitch.
Background technology
Microswitch is also called sensitive switch, because its closure or the instantaneous conversion speed of disconnection are exceedingly fast, therefore controls automatic
It is commonly used to switching circuit in circuit processed；It is generally by pedestal, the handle stretching in this pedestal, the wink motivation being located in this pedestal
Structure and switching mechanism are constituted.One microswitch typically can only control the break-make of a circuit, to realize multiple circuit simultaneously
Switching, it usually needs multiple microswitch are combined and is used in combination；Not only cumbersome, and it is difficult to ensure that multiple micro-
Dynamic switch synchronization action.Make when controlling for signal, then easily cause control signal and can not synchronously be switched on or switched off, lead to signal
Disorderly；When controlling for multiple circuit, then can lead to the instantaneous phase shortage of electrical equipment or short circuit, cause damage.
Content of the invention
For drawbacks described above present in prior art, the present invention is intended to provide a kind of structure is simple, good reliability, can be with
When control four circuit synchronization break-makes combination type microswitch.
To achieve these goals, the present invention employs the following technical solutions：It includes inside and is provided with wink motivation structure and switching
The pedestal of mechanism, the handle stretching in this pedestal, described switching mechanism by the inlet wire plate fixed in the susceptor and outlet board,
And the elastic contact blade being fixed on described inlet wire plate is constituted；Switching mechanism is four groups, and described wink, motivation structure was by being fixed on pedestal
In support, to be fixed on that the other end on this support is fixed with the driving member of spring base, one end is fixed on support be in Ω for one end
The elastic overturning piece of shape, another spring base being fixed on this elastic overturning piece other end, the pressure being fixed between two spring bases
Spring, it is located in pedestal and upper end contacts the top board composition that lower end and each elastic contact blade keep contact with elastic overturning piece.
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, due to employing technique scheme, the elastic force using stage clip realizes elasticity to the present invention
The deformation of rotating sheet or reset, thus synchronously contacting or break by oppressing or unclamping top board and realize each elastic contact blade and outlet board
Open, be finally reached the purpose of four circuit of Synchronization Control；There is repeatable accuracy height, good reliability.Further, since adopting
Metal shell that pedestal is coated, the therefore present invention also have the effect of shielding electromagnetism and Flouride-resistani acid phesphatase.
Brief description
Fig. 1 is the structural representation of the present invention.
In figure：Support 1, metal shell 2, pedestal 3, elastic overturning piece 4, elastic contact blade 5, inlet wire plate 6, top board 7, outlet board
8th, the second outlet board 9, spring base 10, stage clip 11, driving member 12, pressure handle 13.
Specific embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings：
As shown in Figure 1：Wink motivation structure and four groups of switching mechanisms are had, each described switching mechanism is by solid in the pedestal 3 of housing shape
The inlet wire plate 6 being scheduled in pedestal 3 and outlet board 8, to be fixed on inlet wire plate 6 be in that the elastic contact blade 5 of bow font is constituted, and described wink is moved
Mechanism is fixed on the driving member 12 of L-shape structure on this support, is fixed by the support 1 being fixed on above each switching mechanism, one end
It is fixed on the elastic overturning piece 4 in the shape of falling Ω on support 1, is fixed on this bullet in the spring base 10 of this driving member free end, one end
Another spring base 10 of property rotating sheet free end, the stage clip 11 being connected between two spring bases 10, it is located in pedestal 3 and upper end
Contacting lower end keeps the top board 7 contacting to constitute with elastic overturning piece 4 with each elastic contact blade 5；Stretch into pressure handle 13 and the transmission of pedestal 3
Part 12 keeps contact.
In order to ensure that each elastic contact blade 5 can be contacted with top board 7 simultaneously, each fixation above each elastic contact blade 5 free end
There is mutually level second outlet board 9.For safety, and also to improving shielding and Radiation hardness, in pedestal 3 surface bag
It is covered with metal shell 2.
Operation principle：During normal condition, elastic overturning piece 4 is in the shape of falling Ω structure；The elastic force of stage clip 11 is turned over by this elasticity
Rotor pushes down on top board 7, and so that this top board is oppressed, each elastic contact blade 5 is synchronous with corresponding outlet board 8 to be contacted, thus realizing four
Individual circuit synchronization is connected.When pressing pressure handle 13, the counteracting force being subject to top board 7 with elastic overturning piece 4 is gradually increased, elasticity
Rotating sheet 4 elastic deformation amount be also gradually increased；When elastic deformation amount reaches marginal value, the stage casing of this elastic overturning piece is immediately
It is flipped up and forms Ω shape structure, elastic overturning piece 4 instantaneously departs from top board 7；Then each elastic contact blade 5 and corresponding outlet board
8 synchronous disengaging and by top board 7 jack-up, thus realize four circuit synchronization disconnecting.When unclamping pressure handle 13, elastic overturning piece
4 revert to normal condition in the presence of stage clip 11 elastic force, and then each circuit understands synchronism switching to on-state again.
