Problems solved by technology
[0004] Since the whole lead clamp is only connected by the bolt assembly 1, if the bolt and the nut become loose, the contact gap between the upper and lower clamps and the cable will increase, and the contact resistance between the lead clamp and the cable will also increase accordingly. Large, the conductivity of the lead fixture itself is reduced, and the effect of electric energy connection between cables is greatly reduced

The invention discloses a wiring clamp of high-low voltage distribution lines and especially relates to a lead wire clamp used for electric power installation. The electric power installation lead wire clamp comprises an upper wire clamp, a lower wire clamp and a bolt assembly, wherein the bolt assembly comprises a bolt and a nut, the bolt comprises a bolt head and a screw, the nut is provided with a threaded hole in threaded connection the screw, the upper and lower wire clamps are arranged between the head part of the bolt and the nut, and the upper wire clamp and the lower wire clamp are clamped to form a wire clamping hole. The electric power installation lead wire clamp is characterized in that one surface, opposite to the bolt, of the nut is provided with a group of transverse positioning grooves which are distributed in the circumferential direction, and all the transverse positioning grooves are communicated with the threaded hole; the whole bolt is made of aluminum; and the bottom end of the screw is provided with a group of vertical positioning sheets evenly distributed in the circumferential direction, and the vertical positioning sheets are corresponding to the transverse positioning grooves in position and shape. The electric power installation lead wire clamp overcomes the defect in the prior art that the bolt assembly is liable to loose, and the conductive performance of the lead wire clamp is ensured.
Description
technical field [0001] The invention relates to a connection clip for high and low voltage power distribution lines, in particular to a lead wire clip for electric installation. Background technique [0002] Lead clamps (also known as terminal clamps, connectors or parallel trench clamps) are commonly used electrical fittings. According to structural characteristics, lead clamps are divided into bolt type, H type and wedge type. The main structure of the bolt type lead clamp (such as Figure 4 shown) includes upper wire clamp 2, lower wire clamp 4 and bolt assembly 1, wherein bolt assembly 1 is mainly composed of nuts and bolts, and bolt (English: bolt) is a threaded cylindrical rod-shaped object with a head at one end. The cylindrical part of the thread is called a stud, which is used to cooperate with the nut, and the other end is the head, which is called the bolt head. The upper and lower wires are clamped between the bolt head and the nut. The upper wire clamp 2 and the...
