Problems solved by technology

[0002] Most of the existing contactors do not have a safety lock structure. When the contacts of the contactor need to be replaced, the contact support will still move up and down after the arc extinguishing cover of the contactor is removed, which is prone to false contact, causing safety hazards and affecting The safety and stability during the disassembly and assembly of the contactor also makes the disassembly and assembly process inconvenient

Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0033] Such as figure 1 As shown, this embodiment provides a safety lock structure for a contactor. The contactor includes a base 1, a contact support 2, and an arc extinguishing cover 3 installed sequentially from bottom to top. Other structures of the contactor are similar to existing ones. Some contactors are the same, so the description is omitted. The safety lock structure includes a safety lock 4 and a torsion spring, which are installed in the contactor.

[0034] Such as Figure 2-4 As shown, the safety lock 4 includes a long rocker arm 43 and a short rocker arm 44, the long...

Abstract

The invention relates to a safety lock structure for a contactor and the contactor. The safety lock structure comprises a safety lock and a torsion spring; a mounting groove is formed in a base; the safety lock is mounted in the mounting groove; the torsion spring is connected with each of the safety lock and the mounting groove; a safety clamping hole is formed in a contact support; when an arc extinguishing cover is not mounted, the torsion spring drives one end of the safety lock to extend into the safety clamping hole; a boss is arranged on the arc extinguishing cover; and when the arc extinguishing cover is mounted on the contact support, the boss pushes the safety lock to extend into one end of the safety clamping hole to be separated from the safety clamping hole. Compared with theprior art, after the arc extinguishing cover of the contactor is disassembled, the safety lock limits the up and down displacement the contact support, so that the disassembling process of the contactor is safer and more convenient, and safety accidents are prevented when a contact is replaced; and when the arc extinguishing cover is mounted, the safety lock is separated from the contact support,and the contact support can move up and down without affecting the normal work of the contactor.

Description

technical field [0001] The invention relates to the technical field of power supply safety protection, in particular to a safety lock structure for a contactor and the contactor. Background technique [0002] Most of the existing contactors do not have a safety lock structure. When the contacts of the contactor need to be replaced, the contact support will still move up and down after the arc extinguishing cover of the contactor is removed, which is prone to false contact, causing safety hazards and affecting The safety and stability during the disassembly and assembly of the contactor also makes the disassembly and assembly process inconvenient. Contents of the invention [0003] The object of the present invention is to provide a safety lock structure for a contactor and a contactor in order to overcome the defects of the above-mentioned prior art. [0004] The purpose of the present invention can be achieved through the following technical solutions: [0005] A safety...
