Abstract
A waterproof push button switch comprises a base, an underplate, a button and terminals. The base is provided with an upper chamber and a lower chamber. A pitman with a copper bar extends into the upper chamber from the lower chamber. The copper bar is arranged in the lower chamber. The underplate having terminals is sealed at the lower chamber. A seal ring is enclosed on the top of the pitman inside the upper chamber. The button is embedded on the top of the pitman inside the upper chamber. The utility model is applicable for mechanical equipments for field operation and underwater operation.
Description
One, affiliated technical field
The utility model belongs to the button technical field, refers in particular to a kind of waterproof push switch.
Two, background technology
Button is mainly used in electromagnetic starter, contactor, relay and other electric control circuits.The present push-button switch of using on the market, employing be the mode of spring reset, water resistance is poor, is not suitable for the plant equipment of field work and underwater operation.Chinese patent once disclosed a kind of " waterproof push switch ", and (application number: 97125923.2), it mainly is applicable to for example washing machine of control wetting system." a kind of water-proof type push-button switch " (ZL01204105.X), it lays Waterproof glue line by base end face, and the cylinder appropriate location is established sealing ring, the lid inner frieze is established measures such as a circle edge clipping, to reach the purpose of waterproof.
Three, summary of the invention
Task of the present utility model is to provide a kind of waterproof push switch, and it is applicable to the plant equipment of field work and underwater operation.
For finishing above-mentioned task, the solution that the utility model is taked is: a kind of waterproof push switch, comprise pedestal, base, button, terminal, described pedestal has epicoele and cavity of resorption, the coupling bar of one band copper bar enters epicoele from cavity of resorption, and the copper bar is in cavity of resorption, and the base of band edge is encapsulated in cavity of resorption, one sealing ring is inserted in the coupling bar upper end in epicoele, and button embeds the coupling bar upper end in epicoele.
Switch is in normally open.Press the button, the elastic force that overcomes sealing ring makes coupling bar just make copper bar and termination contact, switch connection downwards.Release button resets at the elastic force effect knob down of sealing ring, and the copper bar leaves terminal, and switch is located normally open again.The utility model adopts sealing ring as the part that resets, and sealing ring had both played the effect that resets, and waterproof effect is arranged again.Sealing ring is the form of interference fit with cooperating of pedestal in the pedestal epicoele, can not enter into switch inside (pedestal cavity of resorption) even can guarantee well after water oozes down around the button.
Four, description of drawings
Fig. 1 is the structural representation of present embodiment.
View when Fig. 2 is the present embodiment connection.
Among the figure: 1, pedestal, 2, button, 3, spring, 4, base, 5, terminal, 6, the copper bar, 7, nut, 8, sealing ring, 9, sealing gasket, 10, coupling bar, 11, epicoele, 12, cavity of resorption.
Five, embodiment
Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.
Referring to Fig. 1 and Fig. 2, a kind of waterproof push switch, comprise pedestal 1, base 4, button 2, terminal 5, described pedestal 1 has epicoele 11 and cavity of resorption 12, the coupling bar 10 of one band copper bar 6 enters epicoele 11 from cavity of resorption 12, and copper bar 6 is in cavity of resorption 12, and the base 4 of band edge 5 is packaged in cavity of resorption 12, one sealing ring 8 is inserted in coupling bar 10 upper ends in epicoele 11, and button 2 embeds coupling bar 10 upper ends in epicoele 11.
Referring to Fig. 1 and Fig. 2, a sealing gasket 9 is enclosed within on the external screw thread of pedestal 1, screws on nut 7 then.This design more helps waterproof.Tightening of nut 7 is fixed on the equipment switch well, and the outside sealed pad 9 of water blocks, and can not enter switch inside.
Referring to Fig. 1 and Fig. 2, coupling bar 10 is built-in with spring 3.Coupling bar 10 built-in springs 3 mainly are in order to guarantee that copper bar 6 can contact with terminal 5 well, thereby guarantee the normal break-make of switch.
Present embodiment adopts silica gel to make sealing ring 8, improves water resistance and useful life.
