Abstract

The utility model relates to an electric shock proof plug and a special socket thereof. Convex edges are arranged around the plane of the plug rod of a power supply which is arranged on the plug. A boss inosculated with the front plane of the socket is arranged on the front plane of the socket. Thus, when the plug held by a hand is inserted into the socket or is pulled out of the socket, electric shock resulting from that a finger is contacted with the plug rod of a power supply of the plug due to the convex edges and the boss for blocking the finger is avoided. The utility model has the advantages of simple structure and low production cost. Accidents of electric shock can be effectively avoided.

Description

The plug of protection against electric shock and private jack thereof

The utility model relates to the plug and the private jack thereof of a kind of plug and private jack thereof, particularly a kind of protection against electric shock.

Present widely used plug, the installed surface of its power supply inserted link and its end face in the same way is same plane, supporting with it socket also is a planar structure, like this when hold the plug socket or with plug when socket is extracted, finger just might touch the power supply inserted link of plug, and causes getting an electric shock.

The purpose of this utility model is to provide a kind of plug and private jack thereof of getting an electric shock of preventing.

The utility model is to realize above-mentioned purpose like this: make plug that the end margin in the same way of power supply inserted link is installed, protrude plug power supply inserted link plane 1～7mm is installed; And on the socket cover plane of socket correspondingly, protrude the boss that a shape and big or small and recessed plug-in power pack inserted link plane match, make supply hub on the socket in the boss scope, the amplitude that boss protrudes is consistent with the recessed nearly amplitude in installation power supply inserted link plane on the recessed plug, also be 1～7mm, like this when holding the plug socket or plug transferred in socket, because the boss effect of protruding on cocked bead and the socket on the plug, finger can not touch the power supply inserted link on the plug, has avoided the danger of getting an electric shock.

Because this plug edge protrudes, and socket correspondingly has the protrusion boss, so when holding plug, during its socket or dial-out socket, finger can not touch the plug-in power pack inserted link, the fail safe when having improved operation, avoided the Danger Electric shock risk of plug or group plug, and simple in structure.

Below in conjunction with accompanying drawing the utility model is done concrete detailed description.

Fig. 1 is the front view of plug;

Fig. 2 is the cutaway view of plug along A-A;

Fig. 3 is the front view of socket;

Fig. 4 is the left view of socket.

As Fig. 1, Fig. 2, part (1) and part (2) are the power supply inserted links on the plug, and (3) are the mounting planes of power supply inserted link, and (4) are the edges that the protrusion of end in the same way of power supply inserted link (1) and (2) is installed on the plug, and the amplitude that protrude edge (4) is 1～7mm.

With reference to Fig. 3, Fig. 4, on the horizontal frontal plane (5) of socket (7), a boss (6) is arranged, the amplitude of its protrusion is 1～7mm, all in the boss scope, shape and size that the recessed plane of power supply inserted link is installed on the shape of boss (6) and size and the plug match supply hub.

When holding the plug socket or plug transferred to socket, owing to there is the boss (6) that protrudes on cocked bead (4) on the plug and the socket to block finger, avoided may advancing of power supply inserted link (1) and (2) on the finger contact plug.

Claims

1, the plug of protection against electric shock is broadcast bar (1) and (2) are formed by power supply, and it is characterized in that has the edge (4) of a protrusion around the plane (3) that power supply inserted link (1) and (2) is installed.

2, the plug of protection against electric shock according to claim 1 is characterized in that the amplitude on edge (4) protrusion plane (3) was 1～7mm.

3, the private jack of protection against electric shock is characterized in that the boss (6) that has plane (3) recessed on the plug of a size and shape and the described protection against electric shock of claim 1 to match on the socket horizontal frontal plane (5).

4, the private jack of protection against electric shock according to claim 3 is characterized in that the amplitude that boss (6) protrudes is 1～7mm.
