Cable protection device for avoiding electric leakage after abrasion of joint of wire end and socket

Abstract

The invention relates to the technical field of cables. The invention further discloses a cable protection device for avoiding electric leakage after the joint of a wire end and a socket is abraded. The middle end of an elastic ring is formed by elastically connecting sliding shafts. The top end of the elastic ring is fixedly connected with the bottom end of a connecting rod, and the middle end ofthe connecting rod is movably connected with a supporting shaft. The two positions of the top end of the connecting rod are fixedly connected with the two ends of a connecting rope respectively. Themiddle end of the connecting rope is movably installed on the top side of a rotating shaft. Current passes through an inner core, and certain attraction force is formed between the inner core and a magnet. The magnet penetrates through a lock ring and is adsorbed at the inner core of a sheath. The inner core is pulled upwards under the acting force of the top end. The magnets slides downwards to the sheath at the side wall of the inner core, and no magnetic attraction exists at the sheath. The magnet is pulled back by the elastic ring, and the magnet is pulled back to the outer side wall of the lock ring again, so that the lock ring is loosened immediately when the surface of the sheath is damaged, and the electric leakage position is prevented from being dragged into the socket difficultly.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable protection device for preventing electric leakage after the connection between a thread head and a socket is worn out. Background technique [0002] In recent years, the outside of the cables used are all wrapped with insulating material, which is different from the production and use of two cables exposed to the outside. The safety of cable production is also gradually enhanced. The cables used The scope of the area is also gradually expanding. The terminal of the cable will be connected with various plugs, sockets and the internal structure of the electrical appliance. The inner workings are functioning normally. [0003] The sheath of the cable will be damaged after a long period of use. The damaged part is often located at the connection between the cable and the plug and socket. Most electrical appliances will generate a certain amount of heat when they are used. Aft...

[0003] The sheath of the cable will be damaged after a long period of use. The damaged part is often located at the connection between the cable and the plug and socket. Most electrical appliances will generate a certain amount of heat when they are used. After the heat evaporates upwards, there will be some A certain amount of water vapor is formed, and after turning into water, it will drip on the cable, and may flow along the side wall of the cable to the connection of its terminal. If it starts to crack here, the internal circuit will touch the water, which is easy to let Danger of electric shock caused by accidental use of the user
