Abstract

The invention discloses a safety mechanism and an isolating switch, and relates to the technical field of electrics. The safety mechanism comprises a shell, a sliding block arranged in the shell and a switching-on and switching-off assembly fixedly connected with the sliding block, a safety channel and a sliding way intersecting with the safety channel are arranged in the shell, the sliding block slides in the sliding way under driving of the switching-on and switching-off assembly, a through hole is formed in the sliding block, and the axis of the through hole is parallel to the axis of the safety channel. When the switching-on and switching-off assembly is in a switching-off state, the through hole is located at the intersection point of the slideway and the safety channel. According to the safety mechanism, the sliding block is controlled through opening and closing operation of the opening and closing assembly to open and close the safety channel in the shell, the wiring screw is always located on one side of the sliding block, the breakdown risk of the wiring screw is reduced, meanwhile, in the closing state, a tool can be prevented from disassembling the wiring screw, the danger of electric shock is effectively avoided, and the service life of the safety mechanism is prolonged. And the safety is relatively high.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to a safety mechanism and an isolating switch. Background technique [0002] The isolation switch is a switching device mainly used for isolating power supply, switching operation, and connecting and cutting off small current circuits. In the opening position, there is an insulation distance between the contacts that meets the specified requirements and an obvious disconnection mark; in the closing position, it can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time current. When the isolating switch is connected to the load, it is necessary to transfer the busbar, and the isolating switch fixes the busbar through terminal screws to ensure a stable electrical connection with the load. [0003] The isolating switch has a switch housing and a moving contact carriage. In the prior art, a safet...
