Abstract
Disclosed is an alternating current contactor. The problem that an existing alternating current contact is unreliable in interlocking is solved. The alternating current contactor comprises an installation base. A plug core, a static contact and a connection terminal are arranged in the installation base. A movable contact is arranged on the plug core. The two side walls of the installation base are each provided with an installation groove. An interlocking piece is movably connected into one installation groove. A clamping hole is formed in the plug core. The interlocking piece comprises a first interlocking portion and a second interlocking portion. The interlocking piece is provided with a first position for installation, a second position and a third position, wherein when at the second position, the interlocking piece is pressed by the plug core to enable the second interlocking portion to get away from the side wall of an upper cover, and when at the third position, the interlocking piece is driven by another alternating current contactor to enable the first interlocking portion to be clamped to a clamping hole in the plug core. According to the alternating current contactor, reliable interlocking can be achieved, two alternating current contactors can be attached to each other, the movement stability of the alternating current contactors is ensured, the space needed during installation is reduced, and contactor installation is facilitated.
