Problems solved by technology

[0003] The existing cut-off switch uses an electromagnetic control switch to open or close, including an electromagnet core and a coil sleeved on it. When energized, a magnetic force is generated, and the magnetic force pushes the contacts or contact pieces of the two poles into contact with each other, and the circuit conducts On; but when the pressing force of the electromagnet is small, it is easy to cause poor contact between the contacts, which is prone to failure and damage to the equipment
At the same time, the electromagnetic control cut-off switch is suitable for small current occasions. When the current is 500 amperes, it cannot meet the requirements.

Abstract

The invention discloses a disconnecting switch, which comprises a hand handle, propulsion machinery connected with the hand handle, a contact block and a wire connecting stud bolt. The propulsion machinery is tightly against the contact block. A restoral elastic element is arranged between the contact block and the connection wire connecting stud bolt. The contact block is provided with a block contactor which is matched with a stub bolt contactor on the wire connecting stud bolt to be applied. The propulsion device comprises a shell and a slewing axis arranged in the interior of the shell. The slewing axis is matched with a chute. A slide rod is blocked in the chute. The shell is internally provided with a grade surface which is tightly against the chute. The gradient of the grade surface gradually transmits from low to high. The vertex of the grade surface is provided with a concave pit. The close of the switch is controlled by the manual control, thus solving the problem of great pressing force and being applicable to occasions of heavy current.

Description

technical field [0001] The invention relates to the field of automobile power switches, in particular to a cut-off switch. Background technique [0002] The cut-off switch is widely used in electric drive. It is a control electrical appliance used to automatically connect or disconnect high-current circuits. It can frequently connect and disconnect loads and has a voltage-loss shutdown function. [0003] The existing cut-off switch uses an electromagnetic control switch to open or close, including an electromagnet core and a coil sleeved on it. When energized, a magnetic force is generated, and the magnetic force pushes the contacts or contact pieces of the two poles into contact with each other, and the circuit conducts On; When, but the pressing force of the electromagnet is small, it is easy to cause poor contact between the contacts, which is prone to failure and damage to the equipment. At the same time, the electromagnetic control cut-off switch is suitable for the oc...
