Connection kits for magnetic contactor coils

Abstract

A connection component used for an electromagnetic contactor is disclosed. The component comprises a shell. Two control signal input and output terminals connected to an external power supply, two coil incoming and outgoing line leading-out terminals and two connection parts are symmetrically installed on left and right sides in the shell and a coil is also installed in the shell. The connection parts are sheet-shape roll-up elastic connection parts. One end of each sheet-shape roll-up elastic connection part is provided with a vertical segment and the other end is provided with a through hole. A lower end of the vertical segment is provided with a roughly 90 degree arc bending. A back segment of a horizontal segment of the 90 degree arc bending is provided with a rotation arc bending. The coil is provided with a transverse positioning rib and a vertical positioning rib. The horizontal segment of the 90 degree arc bending is installed between the vertical positioning rib and the coil incoming and outgoing line leading-out terminals. The vertical segment is clamped in the transverse positioning rib. Lower ends of the control signal input and output terminals are plugged with the through holes. The component has advantages that a structure characteristic of each sheet-shape roll-up elastic connection part simplifies a coil incoming and outgoing line leading-out connection terminal structure and reliable connection between the control signal input and output terminals and the coil incoming and outgoing line leading-out terminals is guaranteed.

Description

technical field [0001] The invention relates to a commonly used electrical component in the field of electrical technology, in particular to a connection assembly for an electromagnetic contactor. Background technique [0002] The existing connection between the input and output ends of the control signal and the lead-out ends of the coil inlet and outlet wires mainly uses a detachable rigid bent conductor fixed on the coil, which finally extends out of the contactor housing and exposes a part for The rigid connection method of connecting external power supply has the advantage of less connecting parts, and has been widely used in the market. [0003] However, due to the existing connection method, the coil bobbin will be deformed after winding. When the product is assembled, this rigid connection method requires high dimensional processing accuracy of the conductor and the shell, resulting in high manufacturing costs. It is difficult to assemble at the same time. In addit...

Problems solved by technology

However, the existing rigid direct-connected conductors have many bends and complex shapes. After miniaturization, it is more difficult to process and assemble, and the cost will be higher.
