The utility model is characterized in that the positioning component (the ball 2 and the top spring 4) are arranged on the right end of the switch base 1; the rotating shaft 3 is provided with a semi-circle positioning tooth corresponding to the rotating shaft 3; the base board subassembly 8 and the switch base 1 are connected through two symmetrical button positions 5; the base board subassembly 8 is provided with a plurality of oval perforations to partite each gear static touch plate.
Description
The utility model relates to a kind of rotary electrical equipment switch.
A kind of being widely used on the household electrical appliance such as electric fan arranged at present,, and have the rotary switch that gear is adjusted function with the mode opening and closing power supply of rotary middle spindle.This rotary switch is semi-enclosed, and positioning element is located at the lower end of rotating shaft, causes axially loaded inhomogeneous, movable contact spring is contacted with gear static contact, arc power supply sheet produce the virtual connection phenomenon sometimes.Therefore, dangerous in the use, the life-span is short; Simultaneously, the base plate dress links with 2 tapping screws with switch base, and technology is more loaded down with trivial details.
The purpose of this utility model provides a kind of be placed on the switch base right-hand member and by the positioning element on the straight line of two installing holes, corresponding with it a plurality of semicircle positioning tooths are arranged in the rotating shaft lower end, the rotating shaft end has the protrusion step, guarantee that movable contact spring can and contact bending ear contact like clockwork with the rotating shaft rotation and shift gears with each gear static contact, simultaneously, for guaranteeing to contact well between movable contact spring and bending ear contact and each the gear static contact, the reinforcement of projection is arranged on the movable contact spring and be arc, one pressing spring is arranged between movable contact spring and rotating shaft simultaneously, when contacting with arc power supply sheet with each gear static contact uniform pressure is arranged, thereby have excellent contact with the assurance movable contact spring.
Technical solution of the present utility model is, on the basis of the circular switch base that has rotary switch now, positioning element, stage clip, movable contact spring, base plate dress, gear static contact, curved ear contact, screw, curve ear contact, one and the corresponding a plurality of semicircle positioning tooths of circular switch base right-hand member positioning element are arranged on the rotating shaft of the present utility model, can reliably locate exactly when guaranteeing switch gearshift rotation, the base plate dress adopts two symmetrical button bits to be connected with switch base, the assembly technology simple and fast, improve work efficiency, save cost.
Operation principle of the present utility model is when rotating shaft rotates, the corresponding with it corresponding one by one location of positioning tooth on the positioning element that places circular switch base right-hand member and the rotating shaft, be fixed on movable contact spring and rotating shaft rotation synchronously and location on the step of rotating shaft, when movable contact spring rotates to a certain position, promptly simultaneously and base plate a certain gear static contact and the bending ear contact loaded onto contact i.e. circuit connection.Rotate to the adjacent position, get final product gear shift.When rotating to the movable contact spring center line and overlapping by two installing hole straight lines, movable contact spring one end leaves bending ear contact, and the other end leaves the gear static contact, thus open circuit.The utility model compact conformation, positioning element place circular switch base right-hand member, make the rotating shaft axially loaded even.
The utility model has the advantages that and directly positioning element is placed on the circular switch base symmetrical line, base plate and switch base link with two symmetrical button bits, make simple in structure, compact, dependability is strengthened, and arc movable contact spring reinforcement and stage clip have also guaranteed movable contact spring and gear static contact, the reliable contact of bending ear contact simultaneously, good operability, safety, long service life.
According to Fig. 1 .2.3, the utility model has a circular switch base, and circle centre position has a hole, and the switch base right-hand member has settled location notch with the installing and locating parts.Positioning element, form by top spring 4 and ball 2, rotating shaft has a plurality of semicircle positioning tooths corresponding with positioning element, rotating shaft 3 and circular positioning tooth, the step integral molded plastic of laying movable contact spring forms, movable contact spring 7 is arranged laying under the step of movable contact spring, stage clip 6 is arranged on the sound sheet 7, afterwards rotating shaft 3 is inserted in the centre bore of switch base 1, buckle base portion and adorn 8, base plate is adorned on one side semicircle of 8 inner surface, useful oval perforation is apart from one another by the gear static contact of opening 10, their leg are passed base plate to outside, are bending ear contacts 9 on another half of circle, and leg is also passed base plate to outside, by base plate general assembly 8 and circular switch pedestal 1 that rotary switch is totally-enclosed, both link by two symmetrical button bits 5, and curve ear 11 contacts are work indication terminals, and oval perforation separates the gear static contact, increased the dielectric strength between the gear static contact, the useful life of having improved switch.
