Embodiment 1

[0027] The invention provides a driving assembly of a switch device, such as Figures 1 to 3 As shown, it includes a bobbin a, a static iron core b, a moving iron core c, a coil d, a permanent magnet e, and an elastic member f. The first flange a2 and the second flange a3, the first flange a2 and the second flange a3 are all circular.

[0028] One end of the static iron core b is inserted into the roll portion a1, and one side of the static iron core b is a first plane.

[0029] The moving iron core c can be moved and inserted in the reel part a1, and the moving iron core c is built in the reel part a1. The moving iron core c can move along the axial direction of the static iron core b. The moving iron core c is in the non-energized state of the coil d At the same time, there is a gap between the static iron core b and it is attracted to the side of the static iron core b when the coil d is energized.

[0030] The roll part a1, the first flange part a2, and the second flange...

Embodiment 2

[0047] Such as Figures 4 to 6 As shown, the similarities between Embodiment 2 and Embodiment 1 will not be described here. The difference between Embodiment 2 and Embodiment 1 is that the drive assembly of the switch device also includes a first sleeve i, and the first sleeve i is a magnetic One end of the first sleeve i is sheathed on the permanent magnet e, and the other end of the first sleeve i is located on the side of the permanent magnet e close to the moving iron core c.

[0048] The first sleeve i and the permanent magnet e form a magnetic circuit, and under the action of the first sleeve i, the attraction force of the coil d to attract the moving iron core c can be enhanced.

[0049] The first sleeve i can be a straight cylinder. In the present application, the interior of the first sleeve i is hollow and one end is open, and the open end of the first sleeve i is sleeved on the permanent magnet e and connected to the inner wall of the drum part a1. The closed end o...

Abstract

The invention relates to the technical field of electromagnetic switches, and discloses a driving assembly of a switching device, which comprises a static iron core, a coil, a movable iron core, a permanent magnet and an elastic piece, and is characterized in that one side of the static iron core is a first plane; the coil generates a first magnetic flux due to electrification; the movable iron core can move in the axial direction of the static iron core, a gap is formed between the movable iron core and the static iron core when the coil is not electrified, and the movable iron core is attracted to one side of the static iron core when the coil is electrified; the permanent magnet generates second magnetic flux, the permanent magnet is arranged outside the gap, the second magnetic flux and the first magnetic flux face the same direction at the gap, the side, close to the movable iron core, of the permanent magnet is a second plane, and the second plane is flush with the first plane orfar away from the movable iron core relative to the first plane; and the elastic piece is connected to the static iron core and the movable iron core and used for driving the movable iron core to reset in the direction away from the static iron core. The switch device provided by the invention is relatively small in size.

Description

technical field [0001] The invention relates to the technical field of electromagnetic switches, in particular to a driving assembly of a switch device. Background technique [0002] At present, it involves a drive system such as a switch device containing an electromagnetic coil. The coil structure in this switch device generally adopts a magnetic field generated after the coil is energized to close the moving iron core and the static iron core, so as to close the dynamic and static contacts of this type of switch device. When the dynamic and static contacts need to be disconnected, the power to the coil is cut off, so that the coil loses its magnetic field, so that the moving iron core can be reset under the action of the spring to disconnect the dynamic and static contacts. In order to obtain a suitable suction force, such coils often A coil with a large number of turns needs to be wound, resulting in a large switch volume, which is not conducive to installation on some d...
