Abstract

The utility model relates to a machinery clamping quick connector which is suitable for connecting the guide wires in electric power electricity transmitting and distributing lines and is composed of a guide sleeve, guide wire covering heads, a jaw, a compression spring, a spring seat, and a fusiform pipe. One-way sawtooth-shaped teeth are arranged on the hole wall of the inner cavity of the tapered jaw which is split into two halves. At the time of connecting the guide wires, the guide wires are inserted from the both ends of the connector; the spring force is overcome, and the jaw is pushed to the big head of the fusiform pipe; simultaneously the jaw which is split into two halves is separated, and the guide wires extend into the jaw; the jaw tightly clamps the guide wires through the tension of the guide wires and the resilience of the compression spring; the current flow passes through the connector and is transmitted. The connector has the advantages of convenient operation, rapidity, and firm guide wire connection.

Description

The quick conductor jointer of transmission line

The utility model belongs to the conductor jointer tool, is particularly useful for a kind of mechanical clamping type quick connector tool that built on stilts plain conductor connects in the power transmission and distribution circuit.

At present, in the construction and repairing work of transmission line, use friedly connect, method such as crimping connects lead.The speed of application of joint is slow, the cycle is long, and complex process, difficulty are big, of poor quality, and lead damage and waste are serious.It is 92213933.4 quick lead coupling that Patent Office of the People's Republic of China has announced the patent No. on November 24th, 1993.This coupling can improve wiring speed, when still connecting stranded conductor, is difficult to penetrate the locknut of one, and this coupling many places thread connection, and there is loosening factor in its complex structure, has influence on wiring quality.

The objective of the invention is,, provide a kind of simple and efficient to handle, connect reliable, firm quick conductor jointer in order to improve the operating efficiency and the wiring quality of electric power transmission line construction and repairing.

Basic design of the present utility model is made up of guide pin bushing [1], lead packet header [2], claw [3] compression spring [4], spring base [5], fusiformis pipe [6].Spring base [5] is contained in the centre position of fusiformis pipe [6] and fixes, and its two ends are installed compression spring [4], claw [3] guide pin bushing [1] respectively, dress lead packet header [2] in the guide pin bushing [1].

Accompanying drawing 1 is a structural representation of the present utility model.Accompanying drawing 2 is the A-A cutaway view of Fig. 1.

Reference numeral: [1] guide pin bushing, [2] lead packet header, [3] claw, [3-1] claw positioning key, [4] compression spring, [5] spring base, [6] fusiformis pipe.

Be described in detail structure of the present utility model in conjunction with the accompanying drawings.According to illustrated in figures 1 and 2, the centre of fusiformis pipe [6] is cylindrical for one section, and two ends are conical.Claw [3] is for splitting the cone of two halves, do not misplace when the correspondence position of the cone of two halves has location notch and positioning key [3-1] to guarantee in the claw folding.The tapering of claw [3] is identical with the inner chamber tapering of fusiformis pipe tapered segment.Have zigzag to clamp tooth on the claw internal chamber wall, the sawtooth incline direction is towards prismatic pipe stage casing.Guide pin bushing [1] is installed in two of fusiformis pipe, lead packet header [2] and guide pin bushing [1] be combined with the gap.Fusiformis pipe [6] and claw [3] are manufactured with good metallic conductor

This transmission line quick connector, it is simple to connect technology, and service speed is fast, is connected firmly.Operating time shortened to 1-2 minute by original 2-3 hour, and cost reduces 1/3-4/5, and damage wires not, had reduced the joint waste.Its ampacity and item technical indicators such as resistivity and temperature rise all are better than the lead of corresponding specification, have guaranteed quality of connection.

It is as follows to narrate implementation process in conjunction with the accompanying drawings:

Fusiformis pipe [6] aluminium compo pipe is manufactured, spring base [5] is contained in middle section position, and it is fixing in tube wall upper punch hole, pack into successively and compress spring [4], claw [3] in two ends, with cold forging radially aluminium-alloy pipe is made fusiformis, two ends mounting guide sleeve [1] and lead packet header [2], quick conductor jointer.

During use, plain conductor is inserted lead packet header [2] from the two ends of connector through guide pin bushing [1] respectively, the claw [3] that promotes two ends overcomes the elastic force that compresses spring [4] and moves to fusiformis Guan Daduan, the round end in lead packet header [2] with two claws [3] separately, lead puts in the claw of sawtooth tooth together with packet header, until the big end of claw, utilize the elastic force of compression spring [4] and the gravity of lead then, driving two ends claws [3] moves to the small end of fusiformis pipe, the sawtooth tooth is the lead auto lock, and is to draw tighter and tighter, and the two ends lead connects by connector, current lead-through is finished quick connection.

Claims

1, the quick conductor jointer of transmission line, it is characterized in that this connector is made up of guide pin bushing [1], lead packet header [2], claw [3], compression spring [4], spring base [5], fusiformis pipe [6], spring base [5] is contained in the centre position of fusiformis pipe [6] and fixes, its two is installed compression spring [4], claw [3], guide pin bushing [1] respectively, dress lead packet header [2] in the guide pin bushing [1].

2, the quick conductor jointer of transmission line according to claim 1, it is characterized in that described claw [3] is for splitting the cone of two halves, its tapering is identical with fusiformis pipe tapered segment inner chamber tapering, the correspondence position of two halves cone has location notch and positioning key, have zigzag to clamp tooth on the claw internal chamber wall, its incline direction is towards the stage casing of fusiformis pipe.
