Description

Technical Field

[0001] The utility model relates to the technical field of contactors, in particular to a contactor end cover. Background Art

[0002] A contactor is an electrical device in industrial electronic control technology that uses current flowing through a coil to generate a magnetic field to close the contacts in order to control the load.

[0003] Existing contactors generally consist of two parts, a base and an end cover, and four clamping rods are fixed at the bottom of the two short sides of the end cover. The base and the end cover are fixed by clamping the clamping rods with the clamping seats on the base. However, during production on an assembly line, the operation time of each position is limited. If the workers hastily install the base and the end cover without aligning the clamping rods with the base when splicing them, the clamping rods may break, making the entire end cover unusable and requiring a new end cover to be replaced, causing waste.
