Power line

Abstract

The invention discloses a power line. The power line comprises a wire rod jacket layer, an inflation cavity is formed in a wire rod jacket layer, more than one inner core wires are arranged in the inflation cavity, more than one inner core wires are wrapped through an inner protective layer; more than one locating sleeves are arranged on the wire rod jacket layer in a raised manner, a movable cavity is arranged in each locating sleeve, guide sliding chutes are arranged on two sides of the inner wall of each movable cavity; a piston is arranged in the movable cavity, sliding blocks are arrangedat two sides of the piston; and the sliding blocks are arranged in the sliding chutes in a slide manner. The power line disclosed by the invention can be expanded by inflating the inert gas, so thatthe gap between the locating sleeves close to each other is pulled open after inflation, the power line and the inner wall of the line hole are in expansion contact always, thereby preventing the power line from swinging and displacing; and the internal core wire can be suspended in the power line after the expansion, thereby increasing the shock resistance and the shear resistance.

Description

technical field [0001] The invention relates to the field of electronic wires, in particular to a power cord. Background technique [0002] There are many types of wire materials, such as power cords, cable wires, signal wires, etc. Currently, the power cords that are used more often include inner core wires and outer protective layers. Since the core wire is placed close to the inner wall of the protective layer, when the protective layer is under pressure, the inner core wire will be immediately compressed, resulting in a reduction in the service life of the entire core wire, and poor impact resistance and compression resistance; [0003] In addition, in the equipment, in order to supply the power cord to pass through, a large number of outlet channels will be set up. The space of the outlet channel will be larger than the outer diameter of the power cord. When the equipment is in use, the outgoing wires shake, and during the shaking process, the power cord will continue ...

AI Technical Summary

Problems solved by technology

Since the core wire is placed close to the inner wall of the protective layer, when the protective layer is under pressure, the inner core wire will be immediately compressed, resulting in a reduction in the service life of the entire core wire, and poor impact resistance and compression resistance;

[0003] In addition, in the equipment, in order to supply the power cord to pass through, a large number of outlet channels will be set up. The space of the outlet channel will be larger than the outer diameter of the power cord. When the equipment is in use, the outgoing line shakes, and during the shaking process, the power cord will continue to swing, and the swinging power cord will loosen the solder joint between the power cord and the motherboard, so there is often a problem of de-tinning, and the power cord is short-circuited. Easy to burn, poor fire performance
