Description
Technical field
The utility model belongs to the part field of electric switch.
Background technology
In various types of electric switches, modal is push-button switch and rocker switch.Rocker switch generally include can and corresponding at least two the optional stable operation positions of different optional operator scheme between the rocker component changed.Push-button switch generally includes linear activated button, and this button is by the simple linear motor performance of a definite sequence.
Existing push-button switch adopts slip working method mostly, mainly formed by conduction seesaw, button, Compress Spring, contact, left and right and switch pedestal, one end of Compress Spring is fixedly installed on the button back side, the other end is provided with slide bar, when work, while relying on button to swing, the power of rocking becomes to making slide bar to slide on seesaw, thereby drive control conduction seesaw to swing, make to be arranged on conduction seesaw both ends upper contact and contact with pedestal upper contact, realize switching on and off of circuit.
Its shortcoming of aforesaid way is: slide bar is easy to wear, thereby the wobble accuracy of impact conduction seesaw causes conducting electricity the contact contact sensitivity at seesaw two ends, and button functional reliability is poor.
Utility model content
The utility model is intended to provide a kind of safe and reliable, highly sensitive boxlike push-button switch conversion equipment.
The purpose of this utility model can reach by following measures: boxlike push-button switch conversion equipment, comprise pedestal, pedestal top is provided with moving contact, the make contact plate of moving contact is connected by locking spring with dividing plate, described pedestal end face tightens the slide plate that has been sticked, one end of slide plate is connected with back-moving spring, and back-moving spring is pushed against slide plate on pedestal; Described pedestal bottom surface is respectively equipped with relative push button and cut-off push button, on slide plate, is being provided with and is connecting bayonet socket and disconnect bayonet socket respectively with push button, position that cut-off push button is corresponding; Described push button is connected with a contact pressing plate, the free end of contact pressing plate is provided with the limiting section of anti-back, this contact pressing plate runs through pedestal and connects bayonet socket, press push button, contact pressing plate is pushed contact dividing plate, thereby dividing plate promotes make contact plate and connects circuit, and slide plate blocks limiting section and prevents that contact pressing plate from exiting; Described cut-off push button is connected with a button spindle, and this button spindle front end is and the inclined-plane that disconnects bayonet fittings.
Technique scheme difference with the prior art is: adopt contact pressing plate to promote contacting plate and connect circuit, compare slide bar connection circuit more reliable, in addition, the free-ended limiting section of contact pressing plate can block mutually with slide plate, prevent contact pressing plate rollback, when need to remove contact pressing plate and slide plate block state time, press cut-off push button, because button spindle front end is to coordinate inclined-plane with disconnection opening, button spindle will promote slide plate to the direction motion away from cut-off push button, thereby contact pressing plate is separated with slide plate, contact pressing plate is homing under the promotion of dividing plate, it is open circuit on-state.
Further, described cut-off push button is provided with back-moving spring, can make cut-off push button Quick-return original position.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model boxlike push-button switch conversion equipment embodiment.
Embodiment
As shown in Figure 1: boxlike push-button switch conversion equipment, comprise square pedestal 1, pedestal 1 top is provided with moving contact, and moving contact is made up of make contact plate 2 and dividing plate 3 successively under upper, and make contact plate 2 is connected by locking spring with dividing plate 3.
The bottom surface of pedestal 1 is fixed with push button 6 and cut-off push button 7 from left to right, push button 6 is made up of joint button cap and contact pressing plate 8, contact pressing plate 8 free ends are with the rectangle limiting section 81 that prevents back skating of projection, cut-off push button 7 is made up of cut-off push button cap, push-button reset spring and button spindle 9, and button spindle 9 free ends are by left-to-right downward-sloping inclined-plane.
On slide plate 4, be provided with and connecting bayonet socket and disconnect bayonet socket with push button 6, position that cut-off push button 7 is corresponding respectively; Press push button 6, contact pressing plate 8 runs through pedestal and connects after bayonet socket and contact and promote dividing plate 3, and dividing plate 3 promotes the make contact plate 2 connection circuit that moves up, and rectangle limiting section 81 and slide plate 4 block, and prevent contact pressing plate 8 back skatings.Press cut-off push button 7, mate with button spindle 9 free end inclined-planes owing to disconnecting bayonet socket, when button spindle 9 moves upward, can promote slide plate 4 moves from left to right, make slide plate 4 depart from the limited field of limiting section 81, contact pressing plate 8 separates with slide plate 4, contact pressing plate 8 is homing under the promotion of dividing plate 3, i.e. open circuit on-state, and cut-off push button 7 disconnects under the effect of back-moving spring also homing.
The foregoing is only the detailed description of the utility model preferred embodiment, be not used for limiting the utility model, the embodiment of all similar variations of doing according to creation spirit of the present utility model, all should be contained among the utility model.
