Abstract

The invention discloses a general drop-proof parallel groove clamp and belongs to the technical field of power devices. The problem that a cable clamp in the prior art is small in usage range and high in maintenance cost and makes a cable easy to drop is solved. The general drop-proof parallel groove clamp comprises an upper clamping plate, a lower clamping plate, a bolt and clamping assemblies, wherein the upper clamping plate and the lower clamping plate are connected through a bolt to form a whole, a clamping cavity is formed between the upper clamping plate and the lower clamping plate, an upper clamping body and a lower clamping body which are serially connected with the bolt together are arranged in the clamping cavity, and the clamping assemblies are arranged at two ends of the upper clamping plate. Free clamping space control is achieved by utilizing matched usage of a first movable device and the second movable device, so that the cable clamp is suitable for different sizes of cables and a usage range of the cable clamp is widened, and meanwhile the tightness and stability of cable connection are improved.

Description

technical field [0001] The invention relates to the technical field of electric devices, in particular to a general-purpose anti-fall-off parallel groove clamp. Background technique [0002] Transmission line joints are an important part of high-voltage transmission lines, and their safe operation is of great significance to the safety of the power grid. Overhead line parallel trench clamps and power cable joints are the weakest links in the safe operation of transmission lines. It plays the role of fixing and shunting in the transmission line. At present, the parallel groove clamps on the market can only hold one specification of clamps. For cables of different specifications, different clamps need to be replaced. Therefore, it is necessary to manufacture clamps of different specifications to adapt to different types of cables. The range of use of the cable clip is greatly limited, and when the cable is placed in the cavity, it is easy to slip or even fall off, which will ...
