Abstract
The utility model discloses a novel waterproof switch. A fixed terminal and an elastic terminal are installed on a base. Shafts on a cover plate penetrate through holes in a waterproof sleeve to be riveted onto the base. The waterproof sleeve and the base form a cavity. The fixed terminal and the elastic terminal are arranged in the cavity. Lead wires are fixed to the fixed terminal and the elastic terminal. Glue is arranged in the cavity. A transmission rod and a torsion spring form a rotation mechanism. The shaft of the transmission rod is clamped in the holes on two sides of the base. One end of the torsion spring is pressed against an inclined surface of the transmission rod, and the other end of the torsion spring is pressed against a platform of the base. The base is clamped in buckling holes of a glue casing through buckling bosses arranged on the base. A switch assembly is installed on grooves of the base and a step of the glue casing. A spring is installed on a cylinder of the base. The waterproof switch is reasonable in structure design, good in waterproof function and high in reliability.

Background technology
Water proof switch is applied very extensive in household electrical appliances, Industry Control product, generally comprises Jiao Gai, waterproof cover, moving plate, base, common terminal, Chang Kaiduan, normally closed terminal, shell fragment; Common terminal, Chang Kaiduan, normally closed terminal are installed on base, moving plate is arranged on common terminal, shell fragment is arranged on Chang Kaiduan and moving plate, on Chang Kaiduan, normally closed terminal and moving plate, be respectively equipped with contact, moving plate is under the effect of shell fragment, contact on it contacts with normally closed terminal upper contact, common terminal and normally closed terminal conducting; Button stretches out in Jiao Gai through waterproof cover, while pressing button, button lower reaction is in moving plate, button drives moving plate to move downward, under the effect of moving plate, shell fragment and normal beginning, rotor contact separates with normally closed terminal contact, and rotor contact moves downward and often opens terminal contact and contact, thereby connect common terminal and normal beginning, switch is changed.There is following shortcoming in the sensitive switch of prior art: press button and drive waterproof cover, between waterproof cover and button, can produce motion, the change of shape of this contact position can cause the water resistance of switch unreliable; After button comes downwards to moving plate and changes, button continues descending limited space, causes the mechanism of driving switch button must design accurately, and error volume is little, and cost is high, affects the reliability in switch use procedure.For making up the deficiencies in the prior art, the utility model aims to provide a kind of novel water proof switch.
Utility model content
For the problems referred to above, the utility model aims to provide a kind of novel water proof switch.
For realizing this technical purpose, scheme of the present utility model is: a kind of novel water proof switch, comprises handle, press negative winding stem, handle side platform, glue shell, button bit hole on glue shell, step on glue shell, the circular arc chamber of glue shell, base, button bit boss on base, groove on base, the hole of base both sides, cylinder on base, the platform of base, rotating mechanism, drive link, axle on drive link, drive link head, the inclined-plane of drive link, the tail plane of drive link, the other end of drive link, torsion spring, one end of torsion spring, steady pin, roller, switch module, waterproof jacket, hole on waterproof jacket, cover plate, axle on cover plate, pedestal, flexible terminal, fixed terminal, wire, glue, spring, described fixed terminal and flexible terminal are arranged on pedestal, axle on described cover plate through the hole riveting on waterproof jacket on pedestal, described waterproof jacket and pedestal form a cavity, described fixed terminal and flexible terminal are positioned at cavity, and described wire is positioned on fixed terminal and flexible terminal, and described wire is positioned at the cavity of pedestal and base formation, described glue is positioned at cavity, described drive link, torsion spring composition rotating mechanism, the axle of described drive link is stuck in the hole of base both sides, one end of described torsion spring withstands on the inclined-plane of drive link, the other end of described torsion spring withstands on the platform of base, described base is stuck in by the button bit boss on base in the button bit hole of glue shell, described switch module is arranged on the step on groove and the glue shell on base, on the cylinder of described spring fitting on base.
As preferably, the axle on described cover plate is fastened on pedestal through the hole riveted joint on waterproof jacket.
As preferably, described wire bonds is on fixed terminal and flexible terminal.
The utility model is broken the traditional concept of switch in the past, injects glue or allied substances and solidify sealed cavity in cavity, reaches the object of terminal root waterproof; Under the revolving force effect of torsion spring, drive link head extruding waterproof jacket, waterproof jacket is that silica gel material is made, its pliable and tough characteristic causes the suffered power of drive link to be delivered on flexible terminal, make flexible terminal generation elastic deformation, thereby no longer contact with fixed terminal, current path is in off-state; Press negative winding stem and form driving mechanism through the hole on glue shell.Press pressuring press handle, handle is descending by the tail plane of the drive link of its side platform promotion transmission mechanism, and the power that drive link overcomes torsion spring rotates, and drive link head departs from flexible terminal, the flexible terminal resilience that loses external force restriction contacts with fixed terminal, switch conduction; Discharge handle, handle is returned to initial position under the effect of spring, and transmission mechanism again pushes flexible terminal under the effect of torsion spring, and flexible terminal separates with fixed terminal, and switch disconnects.The utility model reasonable in design, anti-water section and the driving mechanism of switch separate completely, can be because of the water-proof function of the motion effects switch of driving mechanism; Driving mechanism handle is descending to be caused crossing function that stroke splits pass without impact after switch transition, for the external drive mechanism of switch provides larger tolerances in design, has significantly improved the reliability of the safe handling of switch.
