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.
