Abstract

The utility model relates to the technical field of an electric connecting device which comprises two parts of a plug and a socket. The power supply is connected through the inner surface of a barrel-shaped plug pin in the plug to contact with the outer surface of a plug post in the socket. The outer surface of the barrel-shaped plug pin in the plug is covered with an insulating layer. When jacks in the socket are not used, the insulation material in the interior of the socket automatically seals the jacks. Thus, the utility model has the advantages of safe use and simple structure.

Description

Safety plug and socket

The utility model relates to the arrangements of electric connection technical field.

Just widely used plug and socket all has certain unsafe factor at present, power supply connector in the socket and the pin in the plug all are to make with exposed sheet metal, are pulling out or during plug, pin header has begun contact electrification, and the rear portion is still exposed outside, and finger touches and promptly can get an electric shock; The child likes finger is inserted in the socket aperture out of curiosity, also easily touches the power supply connector and gets an electric shock.

The purpose of this utility model provides a kind of safe plugs and sockets, and the metal of the pin in the power supply connector during use in the socket and the plug all is difficult for contacting with staff.

For solving above-mentioned task, technical solution of the present utility model is: safety plug, comprise plug body (1) and the pin of fixedlying connected (3) with it, and it is characterized in that pin (3) is a hollow metal cylindrical shell, its outer surface is covered with insulating barrier (2); Safety socket, the power supply connector (5) that comprises socket (6) and be loaded in it is formed, have plug hole (7) on the socket (6), it is characterized in that power supply connector (5) is bar-shaped, its bottom links to each other with socket (6), its end links to each other with insulation head (8), barred body outer cover one thin type insulation baffle ring (9), and there is a spring (10) bottom of insulation baffle ring (9) around the barred body outside.

In above-mentioned technical solution, pin on the plug (3) longitudinally has groove (4); The corresponding isometrical cylinder of pin (3) on bar-shaped power supply connector (5) and insulation head (8) composition and the plug in the socket.

The utility model compared with prior art, can make jack on the socket when not using, insulation baffle ring (9) and insulation head (8) by its inside block automatically, avoid the child stretch into the finger and get an electric shock, owing to pin on the plug is wrapped up in its surface by one deck insulator, can not get an electric shock simultaneously so touch with hand once in a while yet.

Below in conjunction with drawings and Examples the utility model is described in further detail.

Fig. 1 is the safety plug front view.

Fig. 2 is the safety plug end view.

Fig. 3 is the safety socket front view.

Plug shown in attached Fig. 1 and 2 comprises plug body (1) and two pins (3) of fixedlying connected with it, and pin (3) is hollow cylindrical shell, and its outer surface is wrapped with insulating barrier (2), and pin (3) longitudinally has groove (4).

Socket shown in the accompanying drawing 3 comprises socket (6), have the jack (7) of two patchplugs on the socket (6), the position corresponding with jack (7) is equipped with two bar-shaped power supply connectors (5) in the socket (6), this power supply connector bottom links to each other with socket (6), its end is connected to an insulation head (8), form an isometrical cylinder, column diameter is corresponding with the internal diameter of pin (3) in the plug, cylinder overcoat one insulation baffle ring (9), there is a spring (10) bottom of insulation baffle ring (9) around the cylinder outside, when plug insertion socket, insulation baffle ring (9) moves under the promotion of pin (3) inwards, the metallic interior surface of pin (3) is contacted with the outer surface of power supply connector (5) and conduct electricity, when plug was extracted, insulation baffle ring (9) was reset to the root edge of jack (7) under the effect of spring (10).The utility model is equally applicable to the three phase mains jockey.
