Tightener for pin insulator

Abstract

The invention relates to the field of cable installation, in particular to a tightener for a pin insulator. The tightener comprises a pressing plate, an upper splint and a lower splint, wherein one ends of the upper splint and lower splint are hinged through a first screw rod; a first through hole, a second through hole and a third through hole for a second screw rod to penetrate through are formed in the other end of the upper splint and lower splint; the pressing plate can reciprocate along the first screw rod and the second screw rod; the upper splint and lower splint are respectively provided with a first arc-shaped structure and a second arc-shaped structure which are opposite to match and form a clamping ring used for clamping and embedding an annular side groove of the pin insulator, the pressing plate is located above the pin insulator, the first screw rod and the second screw rod are each provided with a corresponding locking nut, and the pressing plate can move towards the upper splint and lower splint by screwing the locking nuts so that a cable can be pressed on a top groove of the pin insulator. The tightener for the pin insulator can replace a wire binding mode to fixa cable on the pin insulator, and is simple in structure, convenient and fast to use and firm in fixation.

Description

technical field [0001] The invention relates to the field of cable installation, in particular to a wire tightener for pin insulators. Background technique [0002] Pin insulators are usually used to fix high-voltage cables. When in use, the cables are tightly attached to the top or side slots of the pin insulators, and then the cables are bound and fixed with the pin insulators by winding wires. This method is inefficient and the binding method There is no uniform standard for the tightness of the binding and the tightness of the binding. The randomness is large, and it is easy to cause the wire to be not firmly fixed. It will become loose or even loose after long-term use. The wire is usually made of metal wires such as aluminum wires, which are directly wound on the cable sheath, which will cause the cable to loosen. If the sheath is damaged, it is easy to cause dangers such as overheating of the cable or even leakage and short circuit, and the insulated cable will direct...

The wire is usually made of metal wires such as aluminum wires, which are directly wound on the cable sheath, which will cause the cable to loosen. Damage to the sheath may easily cause dangers such as overheating of the cable or even leakage and short circuit, and the insulated cable will be in direct contact with the metal wire, resulting in hidden dangers of leakage
