Clamping device of AC contactor

Abstract

The invention provides a clamping device of an AC contactor, including a clamp body, a locking device and a guide rail. An under-voltage protector includes a control panel and a shell, and the shell is provided with a circular boss at the bottom thereof. The clamp body is provided with a first groove in the top surface thereof. A clamping mechanism is arranged on the clamp body. A locking device is arranged in the clamp body, and the locking device includes an unlocking button and a bilaterally symmetrical locking block. The locking block is provided with a slot. The circular boss is providedwith a bump. The slot in the locking block is matched with the bump on the circular boss. The circular boss of the AC contactor can be clamped into the slot. The circular boss of the AC contactor is inserted into the first groove and can be detachably clamped to the clamp body. A number of clamping elastic parts are evenly distributed in the first groove. The clamp body is detachably clamped to the guide rail. The clamping device of the invention is simple in structure, stable and reliable, and greatly saves time and improves the clamping efficiency.

Description

technical field [0001] The invention relates to the field of electrical equipment accessories, in particular to a clamping device for an AC contactor. Background technique [0002] The existing box clamping device is generally movable clamped on the guide rail, and the guide rail is provided in the cabinet, and the integrated device is clamped on the guide rail. However, this kind of card cannot be used in some specific positions. Connecting device, and the clamping device also has the situation that the clamping is not secure. [0003] Due to the different on-site environments, sometimes it is necessary to use different types of AC contactors, and sometimes they need to be combined for joint use. Since there is no fixation between adjacent AC contactors, it is easy to It caused the AC contactor to slide or fall off, causing the AC contactor to deviate from its original position. In addition, it is easy to cause deformation of the wires of the AC contactor, and even cause ...

[0002] The existing box clamping device is generally movable clamped on the guide rail, and the guide rail is provided in the cabinet, and the integrated device is clamped on the guide rail. However, this kind of card cannot be used in some specific positions. Connecting device, and the clipping device also has the situation that the clipping is not reliable

[0003] Due to the different on-site environments, sometimes it is necessary to use different types of AC contactors, and sometimes they need to be combined for joint use. Since there is no fixation between adjacent AC contactors, it is easy to Caused the AC contactor to slide or fall off, causing the AC contactor to deviate from its original position

In addition, it is easy to cause deformation of the wires of the AC contactor, and even cause the wires to fall off, and the adjacent AC contactors are not fixed, and the installation and removal are very cumbersome
