Problems solved by technology

However, the wiring holes of the contactor body in the above patents are mostly exposed in the air, so water vapor and dust will enter the interior of the contactor body through the wiring holes, damage the electronic components inside the contactor body, and even cause a short circuit, which is safe. Hidden dangers, and the existing contactor body needs to be disassembled to conduct a comprehensive inspection of the contactor body during maintenance, which increases the workload of operators and reduces work efficiency

Abstract

The invention discloses a rotary contactor. The rotary contactor comprises a contactor body, and the top end of the contactor body is provided with a plurality of wiring holes. Sealing structures arearranged in the plurality of wiring holes, connecting plates are hinged to two ends of one side of the contactor body, and adjusting structures are arranged at one ends of the two connecting plates. By arranging the sealing structure, an electric wire can penetrate through the threaded pipe and access contactor body, the threaded pipe is screwed in the wire connecting hole then, the clamping ringslides into the clamping groove from the bottom, a sealing half-ring is tightened, and the wire is clamped by the sealing semi-ring; and by arranging the adjusting structure, anticlockwise rotation ofthe rotating plate and loosening of the two elastic plates of the eccentric wheel can be achieved, the first tooth-shaped crankset is separated from the second tooth-shaped crankset, the connecting plate can rotate around the connecting shaft at the moment to drive the contactor body to rotate, and an operator can comprehensively overhaul the contactor body on the premise that the contactor bodyis not disassembled.

Description

technical field [0001] The invention relates to a contactor, in particular to a rotary contactor, and belongs to the technical field of automatic control systems. Background technique [0002] The contactor body is divided into AC contactor body (voltage AC) and DC contactor body (voltage DC), which is used in electric power, power distribution and power consumption. In a broad sense, the contactor body refers to an electrical appliance that uses a coil to flow through a current to generate a magnetic field to close the contacts in an industrial electrical appliance to control the load. In electrical engineering, because it can quickly cut off the AC and DC main circuits and can frequently switch on and control large current (some types can reach 800 amperes) circuits, it is often used in motors as control objects, and can also be used as a control object. It is used to control electric loads such as factory equipment, electric heaters, working machines and various electric...
