Abstract

The invention discloses a magnetic circuit mechanism of a relay. The magnetic circuit comprises a coil (1), a yoke (2) and a framework (3). Two installing holes are formed in the two ends of the framework (3) respectively. The two ends of the coil (1) are fixed into the corresponding installing holes of the framework (3) respectively. The yoke (2) is in an L shape, the short edge of the yoke is fixed to one side of the framework (3), the long edge of the yoke is attached to the side face of the framework (3) in the axis direction of the coil (1), the two ends of the framework (3) are connected with coil terminal pins respectively, and two sets of limiting structures are arranged at the positions, where the coil terminal pins (4) are arranged, on the two sides of the framework (3) respectively. According to the magnetic circuit mechanism of the relay, the number of components is small, the assembling process is reduced, and framework facture is prevented.

Description

technical field [0001] The invention relates to the technical field of relays, in particular to a magnetic circuit mechanism of a relay. Background technique [0002] When the relay is working, as long as a certain voltage is applied to both ends of the coil, a certain current will flow through the coil, thereby generating an electromagnetic effect. The armature pushes the moving spring through the push rod until the moving spring and the static spring are attracted. When the coil is powered off, the electromagnetic attraction force disappears, the armature returns to its original position, and the moving spring is separated from the static spring. [0003] At present, there is a magnetic circuit mechanism of a relay, which includes a coil, a yoke and a frame. Two mounting holes are provided at both ends of the frame, and the two ends of the coil are respectively fixed in the corresponding mounting holes of the frame. The yoke The iron is L-shaped, the short side is fixed o...
