A street yard clamp for pin insulators

Abstract

The invention relates to the cable installation field and specifically relates to a street code clamp for a pin insulator. The street code clamp comprises a press plate, a hinge plate assembly and two locking bolts, wherein the press plate and the hinge plate assembly are arranged oppositely. The press plate is provided with a line pressing groove. The hinge plate assembly comprises a first clamping plate and a second clamping plate, wherein the first clamping plate and the second clamping plate are provided with a first C-shaped structure and a second C-shaped structure, the opening directions of which are opposite, respectively. The first C-shaped structure and the second C-shaped structure are cooperated to form a clamp ring for clamping an annular side groove of the pin insulator. The first clamping plate and the second clamping plate are superposed. The two locking bolts pass through the press plate, the first clamping plate and the second clamping plate in sequence and realize threaded connection. The clamping plates and the hinge plate assembly are in bolt connection; the hinge plate assembly is arranged in the annular side groove of the pin insulator through a hinge mode; and therefore, operation is convenient, a cable can be fixed firmly and safely.

Description

technical field [0001] The invention relates to the field of cable installation, in particular to a street code clamp for pin insulators. Background technique [0002] Pin insulators are devices used to fix overhead cables, such as figure 1 As shown, the pin insulator 1 is usually provided with a top groove 11 and an annular side groove 12. When used, the pin insulator is fixed on a street yard support or a building, and the cable is close to the top groove or side groove of the pin insulator, and then used The cable is bound and fixed with pin-type insulators in the way of binding and winding. This method is inefficient, and there is no uniform standard for the binding method and the tightness of the binding. If the cable is loose, it usually uses metal wires such as aluminum wires, which are directly wound on the cable sheath, which will cause damage to the cable sheath, and may easily cause dangers such as cable overheating or even leakage and short circuit. Moreover, th...
