Abstract

The invention relates to a bidirectional spinning type electric joint, belonging to devices for realizing electric connection of two leads in a spiral press connection manner. A double-head inner sleeve is formed by integrating a left assembly and a right assembly, and the left assembly and the right assembly are symmetrical bilaterally and have the same structure. The left assembly consists of a cylinder and a variable-diameter shrink tube at the outer end of the left assembly, the cylinder of the left assembly is provided with outer thread, and the variable-diameter shrink tube is divided into 4-8 tongue sheets through axial notches. The device further comprises two same conical shells, each conical shell is internally provided with a through hole formed by articulating a cylindrical hole and a conical hole, and inner thread screwed with the outer thread of the double-head inner sleeve is arranged on the cylindrical hole. The bidirectional spinning type electric joint disclosed by the invention has the characteristics of large fastening gripping strength, small contact resistance and convenience for use.

Description

technical field [0001] The invention relates to a joint used for connecting two electric wires, in particular to a joint appliance which realizes electrical connection by crimping two wires by means of spiral crimping. Background technique [0002] In electricity, the cable connection metal mainly includes equipment clamps and wire lugs. When the equipment line clamp is in use, multiple nuts need to be tightened, which brings troubles to the on-site construction operation. The wire nose needs to be used with special hydraulic tools, which brings inconvenience to the on-site construction, especially the repair workers. Contents of the invention [0003] The purpose of the present invention is to provide a two-way spinning electrical connector with low contact resistance and screw crimping. [0004] The object of the present invention is achieved as follows: a two-way spinning electrical connector, the double-headed inner sleeve is composed of left and right parts that are...
