Belt buckle power plug extension cord

Abstract

The invention discloses a belt buckle power plug extension cord, which comprises a male terminal, a female terminal and a wire, wherein both the male terminal and the female terminal both comprise cylindrical parts and tapered tail parts; the circumference of the cylindrical part of the female terminal is upwardly provided with a plurality of petal-shaped inner protection petals connected in sequence; two sides of each inner protection petal are provided with a tooth chain belt respectively; one tooth chain belt is provided with a zipper head; the inner protection petals and the zipper heads are combined to form a sleeve via the tooth chain belts, and the front ends are folded to coat the tapered tail part of the male terminal; the wire, close to one end of the male terminal, is provided with an outer protection ring convex circumferentially, and the front ends of the folded inner protection petals are placed at the inner side of the outer protection ring. The belt buckle power plug extension cord has the advantages that after the multiple inner protection petals are combined, the front ends are folded and sleeve the tapered tail part of the male terminal, and dual effects of isolating mud or cement mortar and enhancing anti-pulling performance are achieved; and a straight buckle belt and the outer protection ring can help enhance the two functions, and the extension cord can be used in harsh environments such as mud or cement mortar.

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.
