Description
Technical field
The utility model belongs to electric switch part field.
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 connecting or disconnecting 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 highly sensitive, reliability and durability push-button switch switching mechanism.
The purpose of this utility model can reach by following measures: push-button switch switching mechanism, comprise the pedestal with inner chamber, this bottom wall of inner cavity is provided with two the first relative contacts and the second contact, between two contacts, be connected with the pendulum plate of conduction, pendulum plate comprises the pendulum left side at straight plate part and straight plate part two ends, right moved end, a left side for pendulum plate, right swinging end is relative with the second contact with the first contact respectively, pedestal inner chamber roof is respectively equipped with and a left side of putting plate, the left button that right swinging end is relative and right button, between described pedestal inner chamber roof and pendulum plate, be provided with the escapement of insulation, this escapement is connected with pedestal intracavity sidewall by balancing arbor, escapement can swing around balancing arbor, described escapement upper end is provided with respectively and left button, left and right lug boss that right button is relative, is provided with spring and latch in the installing hole of escapement lower end, and latch pushes against pendulum plate under the effect of spring.
Technique scheme difference with the prior art is: between button and pendulum plate, be originally by slide bar is set, slide bar rolls seesaw is swung on seesaw, thereby make contact, now original slide bar is replaced to escapement, thereby utilize the make contact that swings of escapement, compare slide bar, escapement swings and can make to put accurately make contact of plate, and button press switching action can make to put plate switches rapidly between two contacts, the design of escapement makes button switching sensitivity higher.
Further, in order to guarantee to put plate and reliability of contact, the left and right swinging end of described pendulum plate is upturned, and upwarping angle is 30 °.
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 push-button switch switching mechanism embodiment.
Embodiment
As shown in Figure 1: push-button switch switching mechanism, comprise the pedestal 1 with rectangular inner cavity, pedestal 1 bottom wall of inner cavity is provided with columned the first contact C and the second contact D that are made up of conducting metal, the first contact C and the equal external wire of the second contact D.
On base 1 between the first contact C and the second contact D, be connected with the pendulum plate 2 of being made by stainless steel or other conducting metals, the structure flat in the middle of this pendulum plate 2 is, two ends upwarp, putting plate 2 is by left swing moved end, straight plate part and right swinging end from left to right successively, straight plate part is connected with the rotating shaft of pendulum plate, and the angle that upwarps of left swing moved end and right swinging end is 30 °.Left swing moved end is relative with the second contact D with the first contact C respectively with right swinging end, and when pendulum plate 2 swings left, left swing moved end and the first contact C connect, and when pendulum plate 2 swings to the right, right swinging end and the second contact D connect.
Pedestal 1 inner chamber roof is fixed with left button A and right button B, left button A is relative with contact D with the first contact C respectively with right button B, left button A and right button B are by pressure cap and pressing lever composition, and pressure cap is positioned at pedestal 1 outside, pressing lever is positioned at pedestal 1 inner chamber.
Between pedestal 1 inner chamber roof and 2 of plates of pendulum, be provided with the escapement 3 that rubber or other insulating material are made, escapement 3 is connected with pedestal 1 intracavity sidewall by swinging axle.This escapement 3 is peach heart shape, two lug bosses of escapement 3 upper ends are relative with the pressing lever of left button A and right button B respectively, the pressure cap of left button A or right button B is being subject to can driving pressing lever to move downward after downforce, pressing lever can push corresponding escapement 3 lug bosses and move downward, and escapement 3 is swung to the left or to the right.The pointed nose of the lower end of escapement 3, with installing hole, is fixed with spring in installing hole, spring free end is connected with latch 4, and latch 4 pushes against pendulum plate 2 under the elastic force effect of spring.
Press left button A and right button B, thereby escapement 3 is swung to the left or to the right, the left swing of escapement 3 or right pendulum drive latch 4 left swings or right pendulum, meanwhile, swinging of latch 4 also swings the pendulum plate 2 offseting with latch 4, thereby connect the first contact C or the second contact D, the circuit completing between left button A and right button B switches.
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.
