Abstract
The invention discloses a waterproof rocker switch with reliable electric contact, mainly solving the problems of poor electric connecting property of the existing rocker switch and small self-lock force of a button. The waterproof rocker switch is characterized in that a tube cavity (9) in which a spring (7) is embedded is arranged at the upper part of a slide sleeve (8); the lower end of the slide sleeve (8) is provided with a steel ball (10) capable of flexibly rotating; and the steel ball (10) contacts the upper end of a contact bridge (4). The waterproof rocker switch with reliable electric contact has the characteristics of good electric connecting property and large self-lock force of the button.
Description
Technical field
The present invention relates to a kind ofly for the switch on small household appliance, especially a kind ofly electrically contact reliable waterproof rocker switch.
Background technology
Rocker switch is widely used on small household appliance, its version has multiple, structure by a kind of rocker switch is mainly comprised of button, support, pedestal, contact bridge, intermediate terminal, side terminal at present, intermediate terminal and side terminal are fixed on pedestal lower end, contact bridge is placed in and on intermediate terminal, forms seesaw, press contact bridge and can make itself and side terminal contact or separated, realize the closed and disconnected of circuit.Button is plugged on the upper end of support, the lower end of support is provided with spring and sliding sleeve, sliding sleeve withstands on contact bridge, sliding sleeve is that tubulose and lower end are sphere, presses button support and rotates thereupon, can make the lower end edge contact bridge of sliding sleeve slide, 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 spherical and is placed in the trim ring in top cover, and support is connected with trim ring hinge, between support and top cover, is provided with sealing ring.In use, in order to make to form good being electrically connected between contact bridge and side terminal, need spring to have enough elastic forces, but the problem thereupon occurring is the force of sliding friction having increased between support and contact bridge, while pressing button, resistance is larger, feel is astringent, clamping stagnation, malfunction, simultaneously also larger to the wearing and tearing of support and contact bridge, useful life is short, when selecting spring, the elastic force of spring is restricted, unsuitable excessive.Therefore there is following technological deficiency in this rocker switch: 1. the contact between contact bridge and side terminal is little, and 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, encounter because of carelessness button and just there will be misoperation.
Summary of the invention
In order to overcome the little deficiency of existing rocker switch electrical connection properties self-lock force poor and button, the invention provides a kind of reliable waterproof rocker switch that electrically contacts, this electrically contacts reliable waterproof rocker switch and has the large feature of electrical connection properties self-lock force good and button.
Technical scheme of the present invention 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 pedestal lower end, contact bridge is placed in and on intermediate terminal, forms seesaw, button is plugged on the upper end of support, the lower end of support is provided 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 steel ball that can flexible rotating, and steel ball contacts with contact bridge upper surface.
The lower end of described sliding sleeve is provided with the ball-and-socket matching with steel ball, and the edge of ball-and-socket closes up and contains steel ball to centre.
The upper surface of described contact bridge is provided with the bar shaped chute that two end sections are circular arc, and described bar shaped chute is recessed to contact bridge below, and steel ball is positioned at chute.
Described pedestal top is provided with the top cover of protrusion, is provided with trim ring in top cover, and the upper end of support is spherical and is placed in trim ring, and support is connected with trim ring hinge, between support and top cover, is provided with sealing ring.
The present invention has following beneficial effect: owing to taking such scheme, during design, can select the spring that elastic force is larger, make the larger thrust of formation between contact bridge and side terminal, improved electrical connection properties, when pressing button, between steel ball and contact bridge, be rolling friction, reduced frictional resistance, press Laborsaving button, flexible, good hand touch; Owing to having 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 occur yet, safe and reliable.
