Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

As shown in fig. 1-2, the utility model provides a high pressure is with quick separating brake contactor is applied to contactor technical field, and it mainly includes casing 10, quiet contact jaw 20, moves contact jaw 30, base 40, induction coil 50 and iron core 60.

Specifically, one end of the housing 10 is connected to one end of the base 40, forming two working chambers. The stationary contact 20 includes a stationary contact head 21, a connecting rod 22, and an output connecting line 23. The stationary contact 21 is located in the housing 10 and is connected to one end of a connecting rod 22. The other end of the connecting rod 22 passes through the end of the housing 10 remote from the base 40 and is connected to the output connection 23.

The induction coil 50 and the iron core 60 are both disposed in the base 40, and the induction coil 50 is sleeved on the iron core 60. The movable contact end 30 includes a torsion spring 31, a movable contact head 32, an extension rod 33 and an adsorption seat 34. The torsion spring 31 is fixed to the housing 10, and one end thereof is connected to the movable contact 32. One end of the extension rod 33 is connected to the movable contact head 32, and the other end extends into the base 40 and passes through the iron core 60 to be connected to the suction seat 34.

Under the normal power-on condition, the induction coil 50 generates a magnetic field to make the iron core 60 generate a magnetic force, so as to adsorb the adsorption seat 34, the adsorption seat 34 pushes the extension rod 33, and further the movable contact 32 is driven to overcome the torsion force of the torsion spring 31 to effectively contact with the stationary contact 21. When the brake is required to be opened, the induction coil 50 is de-energized, the magnetic field disappears, the iron core 60 no longer has the magnetic adsorption and absorption seat 34, and at the moment, the movable contact head 32 is rapidly separated from the static contact head 21 under the action of the torsional force of the torsion spring 31, so that the rapid brake opening is realized.

It can be understood that, the separation and the contact of the movable contact head 32 and the stationary contact head 21 are both affected by the torsional force of the torsion spring 31, the torsion spring 31 is always in a stressed state, the torsional force of the torsion spring 31 can be changed after long-term use, in order to keep the torsional force of the torsion spring 31 in a proper range, the rotating shaft 12 is convexly arranged on the housing 10, the torsion spring 31 is sleeved on the rotating shaft 12, the torsional force of the torsion spring 31 can be adjusted by manually rotating the rotating shaft 12, and the torsion spring 31 is constantly in an effective working state.
