Abstract
The utility model relates to switchgear, comprising a pedestal, a shell cover mounted on the pedestal, a pair of terminals mounted on the two sides of the pedestal, as well as a handspike pulling provided in the shell cover. One end of the handspike is protruding from the shell cover, the other end corresponding to a rotating shaft which is corresponding and matching to the angle switch driving cog at end of the handspike. The other end of the rotating shaft is permanently provided with a movable contact spring, a spring is arranged between the movable contact spring and the pedestal. Four moving contacts are symmetrically arranged on the sole of the movable contact spring. Two terminals are separately arranged at the protruding steps on the two sides of the pedestal base. The moving contacts on the movable contact spring located between the terminals and the pedestal are corresponding and matching to the terminals, separately. The utility model has the advantages that the abrasion will not take place between the terminals and the movable contact, stable electricity property and long performance life.
Description
Technical field
The utility model relates to a kind of switching device that is used to switch on or off power supply.
Background technology
Traditional switching device generally includes pedestal, be arranged on the pair of terminal of base bottom both sides, be arranged on the end cap on the pedestal, be arranged on the movable contact spring of terminal correspondence position, be provided with spring between pedestal and the movable contact spring, movable contact spring is provided with the corresponding cooperation with terminal of moving contact of four symmetrical distributions, the opposite side of movable contact spring then is provided with slide bar, be arranged with rotating shaft on the slide bar of movable contact spring, be arranged with push rod in the rotating shaft, the angle that is provided with a pair of mutual corresponding matching between push rod end and the rotating shaft outer wall is switched driving cog, and end cap is arranged on the pedestal, push rod is slidingly arranged in the end cap, and then stretch out from end cap the other end.When this switching device uses, whenever press push rod one time, push rod just switches driving cog by angle and acts on rotating shaft, drives rotating shaft and movable contact spring and turns over an angle simultaneously, and make the moving contact on the movable contact spring on terminal, also turn over an angle, thereby realize being switched on or switched off of switching device.But the movable contact spring of above-mentioned switching device is when rotating, because movable contact spring also is subjected to the axial thrust of rotating shaft and push rod, therefore, this movable contact spring is to be close to terminal surfaces to rotate long-term the use all the time, the movable contact spring and the terminal of switching device very easily wear and tear, thereby influence the electrical endurance of switch; In addition, the rotating shaft and the coupling reliability between the movable contact spring of this switching device are relatively poor, easily influence its normal use.
Summary of the invention
When the purpose of this utility model is to provide a kind of switch conduction or cut-out, do not have pivoting friction between switch movable contact spring and the terminal, and movable contact spring connects reliable switching device with rotating shaft.
For realizing the purpose of this utility model, a kind of switching device, comprise pedestal, be arranged on the end cap on the pedestal, be arranged on the pair of terminal of pedestal both sides, and be located in push rod in the end cap, one end of push rod stretches out from end cap, the other end is corresponding with rotating shaft, the angle of roller end is switched the mutual corresponding matching of angle switching driving cog of driving cog and push rod end, the described rotating shaft other end is set with movable contact spring, be provided with spring between movable contact spring and the pedestal, the bottom of movable contact spring is symmetrically arranged with four moving contacts, and two-terminal is separately positioned on the boss of base bottom both sides, moving contact on the movable contact spring between terminal and pedestal, these moving contacts respectively with the mutual corresponding matching of terminal.
The beneficial effects of the utility model are: can not wear and tear between the terminal of this switching device and the movable contact spring, electric property is stable, and is safe and reliable, the life-span is long.
Description of drawings
Fig. 1 is the exploded perspective view of the utility model switching device;
Fig. 2 is the structure cutaway view of this switching device.
Among the figure: 1, pedestal, 11 boss, 2, end cap, 3, terminal, 4, terminal, 5, push rod, 51, angle switches driving cog, 6, rotating shaft, 61, angle switches driving cog, 7, movable contact spring, 71, moving contact, 8, spring.
Embodiment
As illustrated in fig. 1 and 2, a kind of switching device, comprise pedestal 1, be arranged on the end cap 2 on the pedestal 1, link together after being embedded mutually by some columns and hole between pedestal 1 and the end cap 2, be arranged on the pair of terminal 3 of pedestal 1 both sides, 4, and be located in push rod 5 in the end cap 2, one end of push rod 5 stretches out from end cap 2, the other end is corresponding with rotating shaft 6, the angle of rotating shaft 6 ends is switched driving cog 61 and is switched driving cog 51 mutual corresponding matching with the angle of push rod 5 ends, the other end of rotating shaft 6 is equipped with on movable contact spring 7 by column and through hole, be provided with spring 8 between movable contact spring 7 and the pedestal 1, the bottom of movable contact spring 7 is symmetrically arranged with four moving contacts 71, two-terminal 3,4 are separately positioned on the boss 11 of pedestal 1 two bottom sides, and the moving contact 71 on the movable contact spring 7 is positioned at terminal 3,4 and pedestal 1 between, these moving contacts 71 respectively with terminal 3,4 mutual corresponding matching.
When above-mentioned switching device uses, whenever press push rod 5 one time, push rod 5 just switches driving cog 51,61 by angle and acts on rotating shaft 6, drive rotating shaft 6 and movable contact spring 7 and turn over an angle simultaneously, and make the moving contact 71 on the movable contact spring 7 turn over an angle with respect to two-terminal 3,4, and push rod 5 is pressed off and on, and rotating shaft 6 is also correspondingly rotated, moving contact 71 on the movable contact spring 7 is alternately realized contact or is disconnected, thereby realizes the operation that this switching device is connected and cut off between two-terminal 3,4; When movable contact spring 7 rotates, it also is subjected to the axial thrust of rotating shaft 6 and push rod 5, make moving contact 71 on the movable contact spring 7 can overcome the active force of spring 8, and make the moving contact 71 on the movable contact spring 7 leave two-terminal 3,4 surfaces, can realize under the friction situation being switched on or switched off not taking place thereby can make between the movable contact spring 7 of this switching device and the terminal 3,4, prolonged the useful life of switching device with this.
