Abstract

The utility model discloses an all-insulated overhead line jumper clamp, and relates to a wire connecting device for an overhead line of a distribution network. A hook line sleeve (6) and a hook line nut (5) are embedded into a groove at the front end of the inner wall of an insulating outer sleeve (1) in turn; one half of a fixed spring clamp (7) is clamped into the groove of the hook line sleeve (6), and the other half of the fixed spring clamp (7) is clamped into the groove at the front end of the inner wall of the insulating outer sleeve (1); and an insulating cover (2), a wiring hook (3), the hook line nut (5) and a hook line screw (4) are connected in turn from front to back. Except the wiring hook, the other electrified connection parts of the jumper clamp are arranged in the insulating outer sleeve, and an insulating sheath is arranged, so that the insulating property is high, and the safety of operating personnel on a pole is enhanced; equipotential handheld operation can be performed, which is more convenient and quicker than insulating operating rod operation in the conventional other products; and the jumper clamp is convenient to install and disassemble.

Description

A kind of all insulation overhead transmission line jumper clamp

Technical field

The utility model relates to distribution overhead transmission line wire connection device, relates in particular to a kind of all insulation overhead transmission line wire jumper (drainage thread) wire clamp.

Background technology

In the overhead transmission line live line working, usually can use tools for live workings such as insulated jumpers or bypass lead-in wire.Though the Work tool of live line working special use updates, insulation property significantly improve; But the electric connecting armour clamp of insulated jumpers and bypass lead-in wire and overhead wire still adopts exposed metal connecting clamp or gold utensil, without any insulation protection, uses extremely inconvenience, becomes the insulation blank spot in the live line working Work tool.

Urban distribution network complex circuit, many objective factors make that live line working personnel's job area is narrow and small, cause field operation personnel psychology pressure, stress and work fatigue easily, cause the person and equipment breakdown easily.

Still adopt the exposed metal wire clamp or the present situation of gold utensil at insulated jumpers and bypass lead-in wire, press for a kind of insulated jumpers of development and bypass lead-in wire special isolation wire clamp, when guaranteeing live line working, can be convenient, fast, safely insulated jumpers, bypass lead-in wire or other power supply downlead are connected with overhead wire and lock, thereby prevent the unexpected slippage of stube cable, replace existing naked metal wire clamp and imported product fully, eliminate the insulation blank spot of live line working insulated jumpers and bypass lead-in wire.

Summary of the invention

The purpose of this utility model just is to overcome the shortcoming and defect that prior art exists, and a kind of all insulation overhead transmission line jumper clamp is provided.

The purpose of this utility model is achieved in that

One, overall

The utility model comprises insulating coating pipe, insulating lid, wiring hook, hook line screw rod, hook line nut, hook thread casing and fixing spring card;

Its annexation is:

Be inlaid with hook thread casing and hook line nut in the inwall front end groove of insulating coating pipe successively, half snaps in the fixing spring card in the groove of hook thread casing, and second half snaps in the inwall front end groove of insulating coating pipe;

Be connected successively before and after insulating lid, wiring hook, hook line nut and the hook line screw rod.

Its operation principle is:

The utility model and insulated cable are combined into complete drainage thread or wire jumper.During use, by the altitude hot-line operation car operating personnel is transferred near the overhead wire, hand-held this insulating clamp of operating personnel directly is connected with aerial condutor, the hook thread casing is moved forward and hooks together stuck lead with wiring by rotation insulating coating pipe.Electric current conducts with contacting to drainage thread or wire jumper of wire clamp by aerial condutor.

The utility model compared with prior art has the following advantages and good effect:

1, except that the wiring hook, other charged coupling part all places in the insulating coating pipe, has increased insulating sleeve, and good insulation preformance has strengthened operating personnel's fail safe on the bar;

2, can carry out the equipotential hand-held, need adopt the mode of insulating bar operation more convenient and quick than existing other products;

3, installation and removal are convenient;
