Abstract

The invention discloses a mechanical interlocking structure and a multistage contactor comprising the same, and belongs to the technical field of low-voltage control electric appliances. The mechanical interlocking structure comprises an interlocking piece and a locking piece arranged on the interlocking piece. The locking piece comprises an elastic arm and a pair of interlocking heads arranged at one end of the elastic arm. The pair of interlocking heads are arranged and protrude towards one side of the interlocking piece. The mechanical interlocking structure is fixedly installed between two adjacent contactors, meanwhile, the contact assemblies of the two adjacent contactors are provided with the bosses protruding towards the interlocking piece, the bosses can be in elastic lock catch fit with the interlocking heads in the back-and-forth moving process of the contact assemblies, and therefore the interlocking function between the multiple stages of contactors can be achieved. Compared with the structural design that an additional fixing device is needed to fix the interlocking piece on the contactor body in the prior art, the contactor has the advantages of being simpler in structure and more convenient to assemble, the interlocking action is simple and stable, and therefore it is ensured that circuit control is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of low-voltage control appliances, in particular to a mechanical interlock structure and a multi-level contactor including the structure. Background technique [0002] Contactors, also known as electromagnetic switches, are used in electric power, power distribution and power consumption. In a broad sense, a contactor refers to an electrical appliance that uses a coil to flow current to generate a magnetic field, and drives the contacts to close or open through the connecting mechanism to control the load. The working principle of the contactor is: when the coil of the contactor is energized, the coil current will generate a magnetic field, and the generated magnetic field will cause the static iron core to generate electromagnetic attraction to attract the moving iron core, and drive the contact action of the AC contactor. When the coil is de-energized, the electromagnetic attraction force disappears, and ...
