Abstract

The utility model relates to an electric conducting wire joint. The usual method of the electric conductor wire connection is that the outer part of a metal joint adopts hydraulic pressure and detonation pressure to make the metal joint extruded and deformed to impact a conducting wire, but the connection method has the defects of large needed force, long time and unsafe use, or the environment is endangered. In a tube body, the electric conducting wire joint is provided with an aluminum claw, a steel clip, an elastic force device, etc. The elastic force of a spring is acted on the aluminum claw and the steel clip to make the aluminum claw and the steel clip clench the conducting wire to achieve the connection purpose. The electric conducting wire joint has the advantages of safe and convenient use, labour saving and time saving, and does not endanger the environment. The electric conducting wire joint can be widely used for connection tubes and anti-tension tubes.

Description

A kind of electrical lead joint

The utility model relates to a kind of electrical lead jockey, refers in particular to a kind of electrical lead joint.

Electrical lead method of attachment in the past all is that two leads are put into metal joint, takes modes such as hydraulic pressure, detonation pressure to make metal joint crimp in the metal joint outside, thereby compress lead, reach the connection purpose, thisly make metal joint distortion compress the method for lead with external pressure, required strength is big, connect hours is long, or equipment heaviness (hydraulic test can reach several tons of weights), cost height, or harm environment, use dangerously, the operation of going out is made troubles to power department.

The purpose of this utility model be to provide a kind of laborsaving, save time, equipment is light and handy, cost is low, safe in utilization, convenient not environmentally hazardous again electrical lead joint.

The purpose of this utility model is achieved like this, and device aluminium pawl, steel folder, aluminium pawl are near the inwall of body in the body of electrical lead joint, and steel is installed in the aluminium pawl and clamps the steel core of lead, and the aluminium pawl is caught lead and steel folder; An elastic force apparatus is set in body again, this elastic force apparatus is made up of spring base, spring, ratchet, lock pin, sour jujube hook, spring base is fixed in the body, the centre is offered a pin-and-hole that is communicated with body outward, one end of spring is fixed on the spring base, the sour jujube hook connects push-plate and passes spring and ratchet articulates, ratchet is contained in the spring base, and square opening is offered in the centre, pins ratchet with lock pin, when lock pin when square opening is got, ratchet rotates, and the sour jujube hook is deviate from, spring discharges push-plate extruded aluminium pawl, make the reach of aluminium pawl, clamping wire and steel folder.

This electrical lead joint has installed parts such as aluminium pawl, steel folder, elastic force apparatus in body, these parts suppress to be connected and carry out in the body, do not need metal joint crimp, required strength is little, laborsaving, save time, safe in utilization, convenient, do not endanger environment again, equipment is also light and handy.

The utility model is described in further detail below in conjunction with accompanying drawing.

Structural representation when Fig. 1 is electrical lead joint length of spring compressed.

Structural representation when Fig. 2 is the release of electrical lead joint spring.

Fig. 3 is that electrical lead joint elastic force apparatus connects cooperation figure.

With reference to Fig. 1, Fig. 2, device aluminium pawl 9 in the body 10 of electrical lead joint, steel folder 8, parts such as elastic force apparatus, again body 10 two ends are pressed into cone, aluminium pawl 9 is half garden wedge shape, near the inwall of body 10, steel folder 8 devices are in aluminium pawl 9, elastic force apparatus is by spring base 1, spring 7, ratchet 2, sour jujube hook 13, lock pin 6 is formed, and spring base 1 is fixed in the body 10, and the centre is offered pin-and-holes 3 that are communicated with body 10 outward, spring 7 is fixed on the spring base 1, one end of sour jujube hook 13 connects push-plate 5, and during spring 7 compressions, the other end passes spring 7 and tangles ratchet 2, ratchet 2 is contained in the spring base 1, pin ratchet 2 with lock pin 6, steel core 4 is exposed in the front end strip off of lead 11, insert from the two-port of body 10, steel folder 8 is clamped steel core 4, and aluminium pawl 9 is caught lead 11 and steel folder 8; When lock pin 6 was got, ratchet 2 rotated under the effect of spring 7, and sour jujube hook 13 is deviate from, spring 7 discharges, promote push-plate 5 extruded aluminium pawls 9, steel folder 8 is because the two ends of body 10 are cone, force aluminium pawl 9 to advance along the inner conical surface of body 10, Wire sheath 12 is partly also released port, and the steel core 4 of lead is tightly bitten by steel folder 8, and aluminium thigh and steel folder 8 are all tightly bitten by the aluminium tooth on the aluminium pawl 9, make lead 11, aluminium pawl 9, steel folder 8 and body 10 under squeezing action, form tight fit.Reach lead and connect purpose.

With reference to Fig. 3, electrical lead joint elastic force apparatus is made up of spring base 1, spring 7, ratchet 2, ratchet 13, lock pin 6, and spring 7 is fixed on the spring base 1, one end of sour jujube hook 13 connects push-plate 5, the other end passes spring 7, and after spring 7 compressions, sour jujube hook 13 articulates with ratchet 2, ratchet 2 is arranged in the spring base 1, offer square opening 14 in the middle of it, lock pin 6 tops are circular, and the bottom is square, the bottom projected square part of lock pin 6 is injected square opening 14, pin ratchet 2; When needs carry out the electrical lead connection, lock pin 6 to be hit down from pin-and-hole 3 with instrument, its projected square part is deviate from, circular portion falls into square opening 14, and ratchet 2 rotates under the effect of spring 7 elastic force, and sour jujube hook 13 is deviate from, spring 7 promotes push-plate 5 extruded aluminium pawls 9, steel folder 8.

This electrical lead joint is made simple, and each parts all can be preset in the body in the body, and the operation of going out is carried very convenient, can be widely used in splicing sleeve, the strain insulator pipe.
