Description

Technical Field

[0001] The utility model relates to the technical field of AC contactors, in particular to an AC contactor base which is convenient for connecting with a shell. Background Art

[0002] AC contactor is an automatic switching device that connects or disconnects the main circuit of a motor or load. It uses electromagnetic force to close or disconnect the switch. It is suitable for frequent operation and remote control of high-voltage circuits, and has low-voltage release protection. AC contactor usually includes a base and a shell.

[0003] The shell and base of the existing AC contactor are usually fixed with screws or snaps during installation and connection. However, the screw fixation makes the assembly between the base and the shell more complicated, resulting in low assembly efficiency. Since the base and the shell are usually made of plastic material, the shell and the base will undergo shrinkage deformation during assembly by snap fixation. After the base and the shell are disassembled and assembled many times, the shell and the base are easily damaged, resulting in a reduction in the service life of the shell and the base. Utility Model Content

[0004] The utility model provides an AC contactor base which is convenient for connecting with a shell to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An AC contactor base that is easy to connect to a shell comprises a contactor shell and a contactor base, connecting plates are provided on both sides of the bottom of the contactor shell, and clamping holes are provided on the surface of the connecting plates, strip grooves are provided on both sides of the top of the contactor base, sliding rods are provided in the strip grooves, and a push plate is movably provided on the sliding rod, a buckle and a push block are provided on one side of the push plate, a through hole and a push block hole are provided on the side wall of the strip groove, a first limiting groove is provided on the side of the push plate away from the buckle, and a second limiting groove is provided on a side wall of the strip groove away from the through hole, and a spring is provided between the first limiting groove and the second limiting groove.

[0007] Preferably, a avoidance groove is provided in the middle of the connecting plate.

[0008] Preferably, the buckle is inserted through the through hole and snapped into the snap hole.

[0009] Preferably, the push block is inserted through the push block hole and is provided with a rubber pad.

[0010] Preferably, one side of the buckle is provided with a chamfer.

[0011] Beneficial Effects

[0012] The above one or more technical solutions in an AC contactor base that is convenient for connection with a housing provided by an embodiment of the utility model have at least one of the following technical effects:

[0013] The above technical scheme is used to connect the contactor housing and the contactor base during installation, so that the connecting plate is pressed down to the outside of the strip groove, and the bottom of the connecting plate abuts against the buckle. Under the action of the chamfer of the buckle, the buckle moves into the strip groove, and the connecting plate is continued to be pressed down so that the clamping hole and the through hole are opposite to each other. At this time, the push plate is pushed by the elastic force of the spring to clamp the buckle into the clamping hole, thereby completing the installation connection between the contactor housing and the contactor base. During disassembly, the push block is pushed to move the push plate into the strip groove. At this time, the buckle moves with the push plate and disengages from the clamping hole, thereby separating the contactor housing from the contactor base. This effectively solves the problem that the installation connection between the existing AC contactor housing and the base is inconvenient, and the housing base is easily damaged. This not only speeds up the assembly efficiency, but also improves the service life of the contactor housing and the contactor base. BRIEF DESCRIPTION OF THE DRAWINGS
