Background technology
Sensitive switch often uses on various electric equipment products equipment, plays conducting and disconnection effect in circuit.When the sensitive switch operation is used, the Push switch contact, make the stator of switch inside be connected and get final product conducting with moving plate, and when the trip switch contact, switch is replied normality and can be disconnected.But current used sensitive switch, due in the cavity of its switch main body and the stator in cavity, moving plate, with the external world be all open, not sealing.The pernicious gases such as the air in external environment, water, oil, moisture, dust and liquid will enter in the switch cavity along gap, particularly under rugged environment, the impact of environmental factor makes stator, moving plate and the insulation layer between them in cavity be subject to oxidation and corrosion, cause loose contact and form leak resistance, finally causing the sensitive switch permanent damages.How to develop and a kind ofly be applicable to adverse circumstances, can effectively prevent external environment corrosion and oxidation, can permanence use, non-damageable sensitive switch has become urgent problem.
The utility model content
The purpose of this utility model is can't effectively prevent that in order to solve in prior art sensitive switch external environment from, to its corrosion and oxidation, extremely flimsy defect, providing a kind of sealed type sensitive switch to solve the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows:
A kind of sealed type sensitive switch, comprise switch main body, moving plate, switch contact and gland sheet, described moving plate, switch contact are set in turn in the switch main body top, described gland sheet is installed on switch main body by switch contact and moving plate, also comprise elastic sealing strip, described elastic sealing strip is arranged between switch contact and moving plate.
The shape of described elastic sealing strip is identical with the gland sheet.
Comprise cavity in described switch main body, be provided with main stator in described cavity and, from stator, described main stator is connected with main pin, described from stator with from pin, be connected.
The described quantity from stator is 2.
Described elastic sealing strip material is rubber.
beneficial effect
A kind of sealed type sensitive switch of the present utility model, compared with prior art can be suitable for all kinds of adverse circumstances, made sensitive switch obtain the useful life of permanence.Sensitive switch without any gap, has guaranteed clean and dry in cavity with outside, makes the pernicious gas such as outside air, water, oil, dust and liquid can not enter in the switch cavity.Stator, moving plate and the insulation layer between them of cavity the inside can not be subject to any oxidation and corrosion, remain good contact and insulation, have guaranteed the permanent use of switch.Also make the electric equipment products of using this sensitive switch, greatly reduce failure rate, improved the q&r of product, saved cost, reduce the wasting of resources and consumer's use cost, met the policy of conservation-minded society, there is good social benefit.

Embodiment
For making that architectural feature of the present utility model and the effect reached are had a better understanding and awareness, coordinate detailed explanation in order to preferred embodiment and accompanying drawing, be described as follows:
As depicted in figs. 1 and 2, a kind of sealed type sensitive switch described in the utility model, comprise switch main body 1, moving plate 2, switch contact 4 and gland sheet 5, described moving plate 2, switch contact 4 are set in turn in switch main body 1 top, and described gland sheet 5 is installed on switch main body 1 by switch contact 4 and moving plate 2.Moving plate 2 contacts use for the stator with on switch main body 1 inner chamber body 10, thus actuating switch.Switch contact 4, for pressing moving plate 2, impels moving plate 2 to contact with the stator on switch main body 1 inner chamber body 10.5 of gland sheets are fixed on switch contact 4 and moving plate 2 on switch main body 1, and gland sheet 5 and switch main body 1 fixing can adopt to be pasted or the various ways such as screw thread is fixing.Also comprise elastic sealing strip 3, described elastic sealing strip 3 is arranged between switch contact 4 and moving plate 2, can prevent that like this dust, liquid, various pernicious gases etc. from entering into switch main body 1 inside, has guaranteed the drying of switch main body 1 inside and has cleaned.Elastic sealing strip 3 can be designed to circle, as long as can cover the cavity 10 of switch main body 1.
But, for better result of use is arranged, it is identical with gland sheet 5 that the shape of elastic sealing strip 3 can be designed to, cavity 10 scopes of elastic sealing strip 3 protection are larger like this, and whole cavity 10 just seals fully, with the external world without any gap.Same for better result of use is arranged, elastic sealing strip 3 materials can be rubber, and the material characteristic of rubber can better prevent that dust, liquid, various pernicious gases etc. from entering into switch main body 1 inside.Elastic sealing strip 3 adopts the very thin and great elastomeric material of elasticity, on the free movement of the moving plate below it and top switch contact, can not produce any impact.
As shown in Figure 1, Figure 2 and Figure 3, comprise cavity 10 in switch main body 1, be provided with main stator 12 in described cavity 10 and, from stator 11, described main stator 12 is connected with main pin 14, described from stator 11 with from pin 13, be connected.Therefore if need this switch of conducting, only need to allow main stator 12 and get final product from interconnecting between stator 11, also just facilitate main pin 14 and from the interconnecting of pin 13, thereby passed through sensitive switch conducting or open circuit.In sensitive switch, this conduction mode is realized by moving plate 2.Moving plate 2 is conductive material, and switch contact 4 is the insulation material, moving plate 2 under the effect of switch contact 4, to pressing down the main stator 12 of rear direct contact and from stator 11, thus the turning circuit switch, the push switch contact 4, moving plate 2 reinstatements, switch disconnects.
In order to guarantee better result of use, from the quantity of stator 11, can be 2.Also have screwed hole 15 on switch main body 1, while for switch main body 1 and gland sheet 5, carrying out the screw thread fixed installation and use, certainly the fixed installation mode of switch main body 1 and gland sheet 5 also will be with use stickup, welding, the various ways such as engage.
During actual the use, as shown in Figure 4, main pin 14 and connect respectively corresponding circuit from pin 13 after assembled formation, gland sheet 5 is fixed on switch main body 1 and the inside has been installed elastic sealing strip 3, has formed whole sealing.When the conducting of needs sensitive switch, press switch contact 4 and get final product, when the needs sensitive switch disconnects, trip switch contact 4 gets final product.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what in above-described embodiment and specification, describe is principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
