Description
Technical field
The utility model relates to a kind of sensitive switch, particularly a kind of water proof and dust proof sensitive switch that uses in the place of meeting trickle or many dust or pernicious gas that is applicable to.
Background technology
The kind of switch is a lot, and sensitive switch is wherein important a kind of.Common sensitive switch by loam cake be arranged on switch that covers and form, switch can be transferred to associated components in the switch loam cake with outer mechanical force or stroke.Be equipped with in the switch loam cake operation strip with can with the contacted contact of operation strip, also be equipped with on the switch base and be used for the terminal that is connected with external circuit.When operation strip is displaced to critical point, produce instantaneous operation, operation strip terminal moving contact and fixed contact are switched on or switched off fast, final feasible external circuit conducting or the disconnection that is connected with the sensitive switch terminal.
Sensitive switch commonly used is not considered the infringement of water, dirt and pernicious gas corrosion owing in normal environment, use, and sealing device is not set on switch yet.In case run into adverse circumstances; At meeting trickle or many dust or there is the place of pernicious gas to use sensitive switch equipment; Because it does not have sealing device; Therefore hardware in the function that does not possess the anti-pernicious gas of water proof and dust proof, switch will cause adverse effect, even causes the short circuit or the inefficacy of switch.For at meeting trickle or many dust or have in the adverse circumstances of pernicious gas and also can use sensitive switch, the utility model improves sensitive switch.
Summary of the invention
The utility model technical problem to be solved provides a kind of water proof and dust proof sensitive switch; The design sealing device makes sensitive switch possess the function of waterproof and dustproof and anti-pernicious gas; Thereby effectively avoided in the adverse circumstances causing the short circuit or the inefficacy of switch, ensured the normal use of sensitive switch in adverse circumstances because of the infringement of trickle, dust and pernicious gas corrosion.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises pedestal; Be connected with loam cake on the said pedestal; Running through to be arranged on has Chang Kaiduan, normally closed terminal and support on the said pedestal, in said loam cake, being arranged on said Chang Kaiduan and the said normally closed terminal has upper and lower two fixed contacts; In said loam cake, being arranged on has the spring operation strip on the said support, there is a moving contact the relative two fixed contact positions of said operation strip one end, and said operation strip top is provided with switch, and said loam cake is run through on the sub-top of said switch; Between said loam cake and the sub-top of said switch, a flexible gland is set, the sub-top of said switch is run through said sealing shroud and is closely cooperated with it, and said sealing shroud is connected with said loam cake.Said sealing shroud should have suitable physical dimension, and when guaranteeing that switch is in any stroke state, strain does not take place sealing shroud, thus guarantee sealing shroud closely cooperate all the time (cover) be not subjected to displacement at the same position of switch.
Exterior surface is provided with an annular groove around the sub-top of said switch on said, and the young end of said groove is big, and said sealing shroud is provided with the cover edge, and said cover is along being crimped on through the rivet hot mode in the said groove that covers on said.
Between said pedestal and said loam cake, be provided with the elastic tape that seals.
Said Chang Kaiduan, said normally closed terminal and said support are to run through with injection molding way to be fixed on the said pedestal.
The material of said sealing shroud and said elastic tape is a silica gel material.
The material of said fixed contact and said moving contact is a silver alloy, is connected on the copper material through the riveted joint mode.
The utility model has the advantages that: because of adopted sealing setting in junctions such as pedestal, loam cake and switch; Sensitive switch interior metal member and extraneous contacting have been avoided; So it is can play the effect of the anti-pernicious gas of water proof and dust proof well, and simple in structure, safe and reliable.
