Description

Practical PVC power cord of anti-drop

Technical Field

The utility model relates to a cable technical field, specifically speaking especially relates to a practical PVC power cord of anti-drop.

Background

The power cord connector is commonly used for various electrical appliances, and when the existing power cord is used, if the cord is accidentally pulled, the plug can be separated from the socket, so that sudden interruption of the electrical appliance is caused, and therefore, the anti-drop power cord needs to be designed. In addition, when the power line is used in an area with acid-base action, the armor, the lead sheath or the outer protective layer of the power line is often corroded, and the protective layer is failed due to long-term chemical corrosion or electrolytic corrosion, so that the insulation is reduced, and the fault of the power line is also caused. Therefore, a power line with a stable structure and a drop-proof function is required.
