Connector for cable with low voltage and large wire diameter

Abstract

The invention discloses a connector used for a cable with low voltage and a large wire diameter. The connector comprises a joint body, pressing sleeves and tapered clamping blocks, wherein the joint body is a cylindrical conductor which is respectively provided with outer threads at the periphery of each of the two ends; concave holes are formed on the centers of end parts at the two ends of the joint body, and a cable joint is respectively contained in the concave hole on one end part; each of the pressing sleeves is a hollow barrel body which is provided with inner threads at two ends of the inner wall; the two pressing sleeves are respectively matched with outer threads at the two ends of the joint body; two cable joints are placed in the concave holes of the joint body after respectively passing through the pressing sleeve corresponding to each end, and are threaded and pressed with the outer threads at the two ends of the joint body by the pressing sleeves; the tapered clamping blocks are of hollow tapered structures matched with the concave holes of the joint body; the two tapered blocking blocks are clamped in the concave holes at the two end parts of the joint body after respectively penetrating through the two cable joints in a sleeved manner, and are used for clamping a cable. The connector disclosed by the invention can be used for quickly and detachably connecting the cable with the cable or terminal equipment, so that the problems that the existing cable is complex in connecting process, poor in detachable performance and poor in connecting and firming performances are solved.

Description

technical field [0001] The invention belongs to the technical field of electric connectors, and in particular relates to a connector used for intermediate connection of low-voltage large-diameter cables or connection between terminals of low-voltage large-diameter cables and electrical equipment. Background technique [0002] During the electrical installation and construction process, when the low-voltage electrical line is long and the cable length is not enough, the cable usually needs to be extended for use. The usual method of cable lengthening is to cut open the ends of the two butt cables to expose the wire cores, insert the wire cores into the matching metal junction tubes, press them tightly with crimping pliers, and wrap them with yellow wax cloth and insulating tape after the production is completed. The heat-shrinkable sleeve is overcoated, and the flame is baked to make the sleeve close to the joint and tighten to complete the single-phase joint production. In ...
