Buckle power plug extension cord

Abstract

The invention discloses an extension cord of a power plug with a buckle, which includes a male head, a female head and electric wires. There is a tooth chain belt on both sides of the inner protection valve, and one of the tooth chain belts is provided with a zipper puller, and all the inner protection valves are assembled into a sleeve shape through the tooth chain belt and the zipper head. And the front end is folded and wrapped on the tail of the male head cone; a circumferentially protruding outer retainer is arranged on the wire near the male end, and the front end of the folded inner protection valve is placed on the inner side of the outer retainer; its advantages are: multiple After splicing and assembling the two inner flaps, the front end is closed and placed on the tail of the male cone, which has the dual functions of isolating mud or cement slurry and improving pull resistance; both the straight buckle and the outer retainer help to improve these two functions, This enables this extension cord to be used in harsh environments such as mud or grout.

Description

technical field [0001] The invention relates to an extension cord of a power plug; in particular, it is an extension cord of a power plug with a buckle. Background technique [0002] Power plug extension cords are relatively common supplies used to connect fixed sockets and mobile electrical supplies. [0003] Commonly used extension cords are a male head and a female head, with a wire in the middle, a metal insert on the male head, and a jack on the female head; some female heads have a ferrule outside, and the ferrule can wrap The male head plays the role of waterproof or fixing, and the inner side of the ferrule is generally provided with side grooves to prevent disengagement. [0004] Such a setting is sufficient for indoor or normal use, but it is not enough for frequent outdoor use, especially in sludge or cement slurry, because during use, the sludge Or the cement slurry will be stained with the extension cord to increase the weight. When pulling out, the sludge or ...

Problems solved by technology

[0004] Such a setting is sufficient for indoor or normal use, but it is not enough for frequent outdoor use, especially in sludge or cement slurry, because during use, the sludge Or the cement slurry will be stained with the extension cord to increase the weight. When pulled out, the sludge or cement slurry will also generate a lot of suction, and the male or female connector of the general design will be pulled out directly.
