Anti-loosening and convenient-to-install cable fixing device for electrical system

Abstract

An anti-loosening and convenient-to-install cable fixing device for an electrical system relates to the technical field of bullet train electrical systems and comprises an upper clamping seat, the inner bottom of the upper clamping seat is fixedly connected with a first spring, the top of the first spring is fixedly connected with a pressing block movably connected with the upper clamping seat, the bottom of the pressing block is fixedly connected with a movable rod penetrating through and extending to the bottom of the upper clamping base, the bottom of the movable rod is fixedly connected with a piston block, and an air hole penetrating through and extending to the top of the piston block is formed in the middle of the piston block. According to the anti-loosening and convenient-to-install cable fixing device for the electrical system, through cooperative use of the piston block and a clamping block, during use, the piston block is inserted into a piston groove, the piston block extrudes the clamping block into a lower clamping seat, when the piston block moves to the position below the clamping block, the clamping block pops up under the action of a second spring, and the upper clamping seat and the lower clamping seat are connected together in a clamped mode, therefore, the effect of facilitating installation is achieved, operation inconvenience caused by narrow space is avoided, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of motor vehicle electrical systems, in particular to an anti-loosening and easy-to-install cable fixing device for electrical systems. Background technique [0002] The current EMU electrical system is a system composed of low-voltage power supply components, also known as "low-voltage power distribution system" or "low-voltage power distribution line". The electrical system is often associated with automation technology, and an important part of the cable room There are many types of electrical systems in the house, so the number of cables is huge, so it needs to be classified and fixed by the fixing device. [0003] Most of the current cable fixing devices use bolts and nuts to fix the fixing parts on the wall of the motor car, but the internal structure of the motor car is relatively compact, which makes it difficult to install the tools. Loosening the fixing device may cause the fixing device to fall o...

[0003] Most of the current cable fixing devices use bolts and nuts to fix the fixing parts on the wall of the motor car, but the internal structure of the motor car is relatively compact, which makes it difficult to install the tools. Loosening the fixing device may cause the fixing device to fall off, causing the cables to be scattered outside, which is neither beautiful nor safe
