Abstract
The utility model discloses a power line plug comprising a wire connecting seat and two or three wire connecting terminals, the wire connecting seat is respectively provided with two or three blind holes, a mouth part of each blind hole is respectively provided with an annular bulge part, two or three wire connecting terminal are formed in the wire connecting seat in an integrated manner through sulfuration, upper ends of the two or three wire connecting terminals respectively and correspondingly run through the two or three blind holes and extend beyond the blind holes, a protection sleeve is mounted on an outer part of each wire connecting terminal by means of a sliding fit, a bottom part of each protection sleeve is provided with an annular step which forms a sliding fit with an inner wall of the blind hole in which the annular step is arranged, and a spring is connected between a bottom end of each annular step and a bottom face of the blind hole in which the annular step s arranged. The power line plug is simple in structure; and when the power line plug is not used, the protection sleeves outside the wire connecting terminals surround the upper ends of the wire connecting terminals under the resetting and jacking effects of springs, and therefore the wire connecting terminals do not contact with the outside environment, the wire connecting terminals are prevented from corrosion, and the service life of the power line plug is prolonged.
Description
Technical field
The utility model relates to a kind of power-line plug.
Background technology
Common electrical accessorie in power-line plug four lives, it is the joint that electrical equipment connects power supply.Power-line plug comprises junction block and two or three binding posts, two or three binding posts are fixed on junction block and with power line and are connected, during use, two or three binding posts intercalation respectively in the jack of socket panel, are connected on power supply power line.When power-line plug was extracted from socket panel, the binding post on it was externally exposed, corrosion can occur after long-time, thereby have influence on the useful life of power-line plug.
The utility model content
The purpose of this utility model is to provide a kind of power-line plug; when being connected with socket panel; the outer sheath of binding post is held back in blind hole on junction block; when not using; the outer sheath of binding post is enclosed in the upper end of binding post under the jacking effect that resets of spring, to protect binding post not by corrosion.
The technical solution of the utility model is as follows:
a kind of power-line plug, include junction block and two or three binding posts, it is characterized in that: be respectively equipped with two or three blind holes on described junction block, the oral area of each blind hole has respectively annular projection, described two or three binding posts one-body molded in junction block by sulfuration, and the upper end of two or three binding posts correspondence is respectively passed two or three blind holes and is extended, the outside of each binding post is by the sheath that has been slidably installed, the bottom of described sheath has the ring-shaped step that the blind hole inwall with the place is slidably matched, be connected with spring between the bottom surface of the bottom of described ring-shaped step and the blind hole at place.
Described power-line plug is characterized in that: described sheath adopts insulating material to make.
Described power-line plug is characterized in that: the bottom of described junction block is connected with respectively and two or three power lines that binding post is connected.
The beneficial effects of the utility model:
The utility model is simple in structure; when being connected with socket panel; the outer sheath of binding post is held back in blind hole on junction block; when not using; the outer sheath of binding post is enclosed in the upper end of binding post under the jacking effect that resets of spring; make binding post not contact with external environment, protected binding post not by corrosion, thereby extended the useful life of attaching plug.
