Problems solved by technology

[0004] For this reason, the technical problem to be solved by the present invention is to solve the technical problem that the contact pressure changes slowly with the rotation of the rotating shaft, and the stability of the contact force between the moving contact and the static contact cannot be guaranteed during the rotating motion, thus proposing a belt Kick rotary switch with energy storage device to quickly separate or contact the moving contact and the static contact

Embodiment Construction

[0031] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0032] This embodiment provides a sudden jump rotary switch, such as figure 1 As shown, it includes: a base 2, an outer casing 1 that is mounted on the base 2 to form an accommodation space with the base 2, located in the accommodation space, fixed on the base 2 and having a first installation space. The seat 6 is installed in the first installation space, the movable contact frame 5 and the movable frame 4 with the second installation space 40 are respectively restricted by the first limiting device and the second limiting device and cannot rotate, and pass through the The through holes at the top of the outer casing 1 and the middle seat 6 enter the rotating assembly 3 of the second installation space 40, and a driving device i...

Abstract

The invention relates to a snap-through rotary switch. A locking device is arranged on a moving contact frame, a locking structure is arranged on a middle seat; an unlocking device and an elastic assembly are arranged between a movable frame and the moving contact frame; when a rotary assembly rotates within a threshold value range, the moving contact frame is locked on the middle seat under cooperation of the locking device and the locking structure, and the movable frame moves relative to the moving contact frame to compress the elastic assembly so that the elastic assembly can store energy; when the rotary assembly rotates to a threshold value point, the unlocking device drives the locking device to break away from the locking structure, and the moving contact frame moves under the energy storage action of the elastic assembly to drive a moving contact to make contact with or break away from a static contact. The elastic assembly serving as an energy storage device is matched with the locking device and the unlocking device, the moving contact can rapidly break away from or make contact with the static contact, and therefore the contacting force of the moving contact and the static contact of the snap-through rotary switch is stable.

Description

technical field [0001] The invention relates to a sudden jump rotary switch, which belongs to the field of electric switches. Background technique [0002] Isolating switch is the most widely used electrical appliance in high-voltage switching appliances. As the name suggests, it plays an isolation role in the circuit and is used to break and connect the circuit with load. [0003] Chinese patent document CN203134639U is a common rotary small three-pole isolating switch, including a housing, a handle, and a moving contact, a static contact, a spring, a rotating shaft, a connecting rod, a bracket, a screw, and a connecting terminal arranged inside the housing. The bottom surface of the housing forms two partition walls to divide the bottom surface into three contact spaces. The three sets of terminals are respectively arranged at both ends of the contact space on the bottom surface of the shell. Above the head, the spring is arranged under the moving contact, the partition w...
