[0001] The utility model relates to the technical field of isolating switches, in particular to a high-voltage isolating switch. Background Art

[0002] The isolating switch is used to isolate the power supply, perform switching operations, and connect and disconnect the current circuit. The isolating switch consists of an isolating switch body, a wiring slot, and an opening and closing device. When used in a high-voltage circuit, the wires are inserted into the wiring slot and squeezed by tightening the screws to make the wires stably contact with the electrode sheets, and the electrode sheets are connected to the poles. When cutting off the current circuit, the opening and closing device is rotated to cut off a pair of poles in the isolating switch body, thereby isolating.

[0003] The inventor found in his daily work that when the isolating switch is in use, when fixing the wires to the wiring slot at the bottom of the isolating switch, the worker needs to hold the wires with one hand to keep them inserted into the wiring slot to prevent the wires from falling out of the wiring slot, and use the other hand to screw the screws to fix the wires, which may make it more troublesome to fix the wires in the wiring slot.

[0010] The effect achieved by the above components is that the auxiliary wires are inserted into the two semicircular clamping blocks by setting the sliding surface.

[0011] Preferably, the arc surface of the semicircular clamping block is fixedly connected with a rubber pad.

[0012] The effect achieved by the above components is: by arranging the rubber pad, the friction between the wire and the semicircular clamping block is increased.

Then the worker screws the screw to fix the wire on the electrode sheet, thereby avoiding the need for workers to hold the wire by hand when installing it, and facilitating the installation of the wire. By setting a slide bar 24, the slide bar 24 is a square column, which limits the semicircular clamping block 21, and by setting a sliding surface 25, the wire is assisted to be inserted into In the two semicircular clamping blocks 21, by setting rubber pads 23, the friction between the wires and the semicircular clamping blocks 21 is increased.
