Abstract
The utility model relates to a waterproof rocker switch with reliable electric contact. With utilization of the waterproof rocker switch, problems that the existing rocker switch has the poor electric connection and the self-locking force of a button is low can be solved. The waterproof rocker switch is characterized in that a tube cavity (9) for placing a spring (7) is arranged at the upper portion of a sliding sleeve (8); a steel ball (10) that can rotate flexibly is arranged at the lower end of the sliding sleeve (8) and is contacted with an upper end surface of a contact bridge (4). The provided waterproof rocker switch has the characteristics of good electric connecting performance and a large button self-locking force.
Description
Technical field
The utility model relates to a kind of for the switch on the small household appliance, especially a kind ofly electrically contacts reliable waterproof rocker switch.
Background technology
Rocker switch is widely used on the small household appliance, its version has multiple, mainly formed by button, support, pedestal, contact bridge, intermediate terminal, side terminal by a kind of structure of rocker switch at present, intermediate terminal and side terminal are fixed on the pedestal lower end, contact bridge places and forms seesaw on the intermediate terminal, pressing contact bridge can make it with the side terminal contact or separate the closed and disconnected of realization circuit.Button is plugged on the upper end of support, the lower end of support is equipped with spring and sliding sleeve, sliding sleeve withstands on the contact bridge, sliding sleeve is that tubulose and lower end are sphere, presses the button support and rotates thereupon, and the lower end edge contact bridge of sliding sleeve is slided, under the effect of spring, sliding sleeve has two static position, i.e. the both sides of lifting up activity supporting point of contact bridge, and the location of the tactile bridge that achieves a butt joint.Pedestal top is provided with the top cover of protrusion, and the upper end of support is for sphere and place the interior trim ring of top cover, and support is connected with the trim ring hinge, is provided with sealing ring between support and the top cover.In use, form good being electrically connected between contact bridge and the side terminal in order to make, need spring to have enough elastic forces, but the problem that thereupon occurs is the force of sliding friction that has increased between support and the contact bridge, resistance is bigger when pressing button, feel is sent out puckery, clamping stagnation, operate dumbly, the wearing and tearing to support and contact bridge simultaneously are also bigger, and useful life is short, the elastic force of spring is restricted when selecting spring for use, and is unsuitable excessive.Therefore, there is following technological deficiency in this rocker switch: 1. between contact bridge and the side terminal to contact pressure little, electrical connection properties is poor; 2. because the elastic force of spring is little, cause the self-lock force of button when unlatching or off-position less, run into button because of carelessness and misoperation will occur.
The utility model content
In order to overcome the little deficiency of self-lock force of existing rocker switch electrical connection properties difference and button, the utility model provides a kind of reliable waterproof rocker switch that electrically contacts, and this electrically contacts reliable waterproof rocker switch and has the big characteristics of self-lock force that electrical connection properties reaches button well.
The technical solution of the utility model is: a kind ofly electrically contact reliable waterproof rocker switch and comprise button, support, pedestal, contact bridge, intermediate terminal and side terminal, intermediate terminal and side terminal are fixed on the pedestal lower end, contact bridge places and forms seesaw on the intermediate terminal, button is plugged on the upper end of support, the lower end of support is equipped with spring and sliding sleeve, the top of sliding sleeve is provided with the tube chamber of inserting spring, and the lower end of sliding sleeve includes the steel ball that can rotate flexibly, and steel ball contacts with the contact bridge upper surface.
The lower end of described sliding sleeve is provided with the ball-and-socket that matches with steel ball, and the edge of ball-and-socket closes up to the centre and contains steel ball.
The upper surface of described contact bridge is provided with the bar shaped chute that the cross section is circular arc.
Described pedestal top is provided with the top cover of protrusion, is provided with trim ring in the top cover, and the upper end of support is for sphere and place trim ring, support to be connected with the trim ring hinge, is provided with sealing ring between support and the top cover.
The utlity model has following beneficial effect: owing to take such scheme, can select the bigger spring of elastic force during design for use, make the bigger thrust of formation between contact bridge and the side terminal, improved electrical connection properties, when pressing button, be rolling friction between steel ball and the contact bridge, reduced frictional resistance, it is laborsaving, flexible to press button, good hand touch; Owing to increased the elastic force of spring, increased the self-lock force of button in enable possition and off-position, do not note touching button and misoperation can not take place yet, safe and reliable.
