The seesaw switch can resist water and dust, and has the characteristics of simple structure, low cost and excellent dustproof and waterproof effects.

Description

A kind of rocker switch

Technical field:

The utility model relates to a kind of switch that is used on the small household appliance, belongs to a kind of rocker switch.

Background technology:

Rocker switch is widely used on the small household appliance, its version has multiple, mainly form by a kind of structure of rocker switch at present by pedestal, support, Ji Gai, contact bridge, middle-end, bent-up end, middle-end and bent-up end are fixed on base and cover, contact bridge places and forms seesaw on the middle-end, press contact bridge and can make it with bent-up end contact or separate, realize the closed and disconnected of circuit.Support and pedestal are hinged, and the lower end of support is equipped with spring and gland, and gland withstands on the contact bridge, reversing support can make gland be in the both sides that contact bridge is lifted up activity supporting point, under the effect of spring, achieve a butt joint and touch the location of bridge, the button of pressing the connection of support top during operation gets final product.Because support is movable part, all there is the gap between support and the pedestal and between button and the pedestal, can not waterproof and dustproof, in water enters pedestal, can cause electric leakage or short circuit, use dangerous; In dust enters pedestal, easily make the support activity dumb, dust enters between contact bridge and the terminal, also can hinder contacting of contact bridge and terminal, causes loose contact.

The utility model content:

Can not waterproof and dustproof deficiency in order to overcome existing rocker switch, the utility model provides a kind of rocker switch, this rocker switch is waterproof and dustproof, have simple in structure, cost low and the water proof and dust proof good effectiveness.

The technical solution of the utility model is: this rocker switch comprises pedestal, support, base lid 3, contact bridge, middle-end and bent-up end, middle-end and bent-up end are fixed on base and cover, support and pedestal are hinged, the lower end of support is equipped with spring and gland, it is to lift up on the contact bridge of activity supporting point that gland withstands on middle-end, the upper end outer surface of support is a spherical, with have manhole on the pedestal of corresponding position, support upper end, be provided with sealing ring between support and the pedestal, described sealing ring is fixed by the gland that is connected on the pedestal.

Described gland and pedestal are one by ultrasonic bonding.

Have circular deep gouge on the described pedestal, sealing ring places in the described deep gouge.

Described support upper end has centre bore, is plugged with button in centre bore.

Described rocker switch is the two-phase switch.

The utlity model has following beneficial effect: owing to take such scheme, be provided with sealing ring between support and the pedestal, sealing ring cooperates with the spherical of support upper end, the better seal effect is arranged, can effectively stop water, dust etc. to enter in the pedestal, simple in structure, cost is low, and water proof and dust proof is effective.

Accompanying drawing 2 is exploded views of the present utility model.

1-pedestal among the figure, 2-support, 3-Ji Gai, 4-contact bridge, 5-middle-end, 6-bent-up end, 7-spring, 8-gland, 9-button, 10-through hole, 11-sealing ring, 12-gland, 13-deep gouge, 14-centre bore.

Embodiment:

The utility model is described in further detail below in conjunction with accompanying drawing:

By Fig. 1 in conjunction with shown in Figure 2, this rocker switch comprises pedestal 1, support 2, base lid 3, contact bridge 4, middle-end 5 and bent-up end 6, middle-end 5 is fixed on the base lid 3 with bent-up end 6, support 2 is hinged with pedestal 1, the lower end of support 2 is equipped with spring 7 and gland 8, gland 8 withstands on middle-end 5 to lift up on the contact bridge 4 of activity supporting point, the upper end outer surface of support 2 is a spherical, with have manhole 10 on the pedestal 1 of corresponding position, support 2 upper end, be provided with sealing ring 11 between support 2 and the pedestal 1, described sealing ring 11 is fixing by the gland 12 that is connected on the pedestal 1.Sealing ring 11 cooperates with the spherical of support 2 upper ends, and the better seal effect is arranged, and can effectively stop water, dust etc. to enter in the pedestal 1, and simple in structure, cost is low, and water proof and dust proof is effective.

Described gland 12 is one with pedestal 1 by ultrasonic bonding.Make sealing ring 11 difficult drop-offs, utilize ultrasonic bonding fast convenient, the efficiency of assembling height.

By shown in Figure 1, have circular deep gouge 13 on the described pedestal 1, sealing ring 11 places in the described deep gouge 13.Be beneficial to sealing ring 11 location, be convenient to assembling.

By shown in Figure 1, described support 2 upper ends have centre bore 14, are plugged with button 9 in centre bore 14.Button 9 can adopt alternate manner with being connected also of support 2, and the structure of present embodiment mainly is in order to process with easy to assembly.

In conjunction with shown in Figure 2, described rocker switch is the two-phase switch by Fig. 1.Can make two-phase break-make simultaneously, safe and reliable.
