A kind of armored cable mechanical locking joint

Abstract

The invention is a mechanical interlocking connector for armoured cables and particular a mechanical interlocking connector for connecting an armoured cable and a device, and relates to the technical field of mechanical equipment. The mechanical interlocking connector is composed of a pin, a U-shaped rack, an inner cone, an outer cone, a jig body, a spring spacing sheet, a cable protection spring, bolts, screw rods, spring washers, compression nuts and an armoured cable. The profile of the jig body is a circular column. A through hole is formed in the upper part of the jig body in the axial direction, and a bell mouth is formed in the lower part of the jig body. The through hole in the axial direction of the jig body is intercommunicated with the bell mouth. Connection holes are formed at two sides of the jig body in the axial direction. The bell mouth of the jig body is internally sleeved with the outer cone and the inner cone in sequence. The armoured cable passes through the through hole of the jig body in the axial direction. An external steel wire of the armoured cable is clamped between the jig body and the outer cone. An inner steel wire of the armoured cable is clamped between the outer cone and the inner cone. The U-shaped rack tightly compresses an interlocking combined cone formed of the jig body, the outer cone and the inner cone through the bolts and the compression nuts.

Description

technical field [0001] The invention relates to a mechanical locking joint for armored cables, in particular to a mechanical locking joint for connecting armored cables and equipment, and belongs to the technical field of mechanical equipment. Background technique [0002] Armored cable is a kind of cable wrapped with protective steel tape or steel wire on the outer layer of ordinary power and communication cables. Its application scope includes: power cables buried underground, submarine communication cables, etc. The armored cable is generally an outer steel wire sheath or a cable with two outer layers arranged at a certain pitch and steel wires in opposite helical directions. In the fields of offshore oil, scientific research, etc., in addition to the advantages and application fields of traditional armored cables, the steel wires (one or two layers) of armored cables can carry underwater equipment through mechanical locking joints. The release system realizes the retrac...

AI Technical Summary

Problems solved by technology

[0004] At present, the mechanical locking joint between the armored cable and the equipment in the world is generally directly pressed by a cone, and each steel wire is not specially fixed. Therefore, in practical applications, not only the installation process is cumbersome, but the steel wires are easily arranged. , uneven force, and the steel wires are easy to overlap each other, which may cause the safety hazard of steel wire extrusion and fracture
