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 present invention relates to a sudden jump rotary switch. A locking device is provided on the moving contact frame, a locking structure is provided on the middle seat, and an unlocking device and an elastic assembly are arranged between the movable frame and the moving contact frame. When the rotating assembly rotates within the threshold range, the moving contact frame is locked on the middle seat under the mutual cooperation of the locking device and the locking structure, and the moving frame is relative to the moving contact The frame moves to compress the elastic assembly to store energy. When the rotating assembly rotates to the threshold point, the unlocking device drives the locking device to separate from the locking structure. It moves under the action of stored energy to drive the moving contact to contact or separate from the static contact. Through the energy storage device of the elastic component and the locking device and the unlocking device, the moving contact and the static contact are quickly separated or contacted, thereby obtaining a kick rotary switch with stable contact force between the moving contact and the static contact.

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...
