Abstract

Provided is a wire connecting pipe for connecting electric wires. The wire connecting pipe not only allows convenient, rapid and safe electric wire connection and meanwhile achieves the aims of sealing, insulating and protecting electric wire cores, but also eliminates the need of twisting and jointing electric wire cores together during the hot-line electric wire connection, thereby preventing the electric shock danger which may be caused when electric wire cores are being twisted and jointed. A conductive wire-clamping piece is arranged in an insulating casing. Each of two ends of the insulating casing is equipped with a sealing ring. After electric wire heads are inserted into the sealing ring, when the electric wire heads are pulled back, the conductive wire-clamping piece pierces insulating layers of electric wires and grips electric wire cores, and then the inserted electric wire heads are tightly clamped in the insulating casing, thereby realizing the aim of connecting electric wires.

Description

Wire barrel

Affiliated technical field

The utility model relates to a kind of termination that connects electric wire, especially can be safely, the wire barrel that easily electric wire connected.

Background technology

At present, in power circuit is installed, in the time of need two wires being connected: strip off the end of a thread partial insulative layer, the electric wire core that the end of a thread strip off place is exposed is twisted joint together, and with insulating tape exposed electric wire core is wrapped up, and reaches the purpose of insulation protection.But present electric wire connected mode is too loaded down with trivial details: need the insulating barrier strip off of electric wire be twisted joint the electric wire core together, wrap up with insulating tape.And the insulating tape easy ageing can not play the effect of sealing, insulation.Have, under special circumstances, electric wire needs hot line job, the danger that the present mode of connection causes the operator to get an electric shock easily when twisting joint the electric wire core when connecting again.

Summary of the invention

Too loaded down with trivial details in order to solve present electric wire connected mode; The insulating tape easy ageing can not play the effect of sealing, insulation; And when hot line job; The weak point that the present mode of connection causes the operator to get an electric shock when twisting joint the electric wire core easily, the utility model provides a kind of wire barrel, the connection electric wire that this wire barrel can not only be convenient, fast, safe; Can reach simultaneously the purpose of sealing, insulation, protection electric wire core; And when hot line job connects electric wire, need not the electric wire core be twisted joint together the danger of having got an electric shock when having avoided twisting joint the electric wire core.

The utility model solves the technical scheme that its technical problem adopted: in insulation crust, a conduction card line plate is set, at the insulation crust two ends, a sealing ring is arranged respectively.After electric wire the end of a thread passed sealing ring and inserts, electric wire the end of a thread was when pulling back, and the conduction card line plate pierces through electric wire insulation layer, sting on the electric wire core, and the electric wire the end of a thread that inserts is stuck in insulation crust, thus reach the purpose that connects electric wire.

The beneficial effect of the utility model is: connection electric wire that can be convenient, fast, safe, the effect of sealing, insulation, protection electric wire core is arranged simultaneously, when having avoided twisting joint the electric wire core and insulating tape cause the danger of electric leakage, electric shock after aging.This wire barrel is simple in structure, is convenient to make.
