Abstract

The utility model relates to a safety pin and socket which is composed of a plug and a socket. Both sides of the lower part of a plug shell 1 are provided with holes. The lower ends of the two electrical-contact elements 2 of the plug are raised, and the upper parts of the electrical-contact elements 2 of the plug are electrically connected with wire-connection sheets 4 in the plug shell through two flexible electrical conductors 3. A spring 6 which makes the raised parts of the electrical-contact elements of the plug to extend out of the holes on the lower part of the plug shell is arranged in the plug shell. The bottoms of jacks 11 of a socket shell 8 are recessed to the side, and concave parts which can accommodate the raised parts of the electrical contact elements 2 of the plug are formed. The electrical contact elements 9 of the socket are fixed on the sidewalls of the concave parts. The electrical contact elements in the socket of the utility model can not be contacted by common conducting body. Thus, the accident of the electric shock caused by contacting the electrical contact elements by common conducting body is avoided, and the use is safe.

Description

Safety pin and socket

The utility model relates to a kind of plug and socket, belongs to the electrical connector field.

Present general electrical connector, plug all uses the electric contact piece of sheet shape or cylindricality directly to insert socket, this structure may be because of causing electric shock accidents with the electric contact piece in other conductor false touch and the socket, and produce risk of short-circuits when the wet environment neutralization dabbles.

The purpose of this utility model provides a kind of safe and reliable electric connector, makes the interior electric contact piece of socket that can't touch this electric connector with the common metal thing, with the electric shock accidents of avoiding causing therefrom.

The purpose of this utility model is achieved in that a kind of Safety pin and socket is made up of plug and socket, said plug has plug body and plug electric contact piece, said socket has jack housing and socket electric contact piece, and said jack housing is opened jack, and said socket electric contact piece is contained in the said jack.In addition:

The both sides of said plug body bottom have the hole; The lower end projection of said plug electric contact piece, its top realizes being electrically connected with the lug plate in the plug body by flexible electrical conductor; The spring that the lower end jut that makes the plug electric contact piece stretches out outside the two side holes of plug body bottom is housed in the plug body;

The jack bottom of said jack housing is recessed to avris, and formation can be held the recess of said plug electric contact piece jut, and said socket electric contact piece is fixed in this recess sidewalls place.

After making said spring pressurized with external force, the lower end jut of said plug electric contact piece is inside retraction just, and plug can successfully insert socket or extracted from socket this moment.Behind the plug insertion socket, the lower end jut of said plug electric contact piece is the recess of the jack bottom avris of corresponding said socket just, and under the effect of the spring that discharges, closely contact, thereby realize being electrically connected function with the socket electric contact piece that is fixed in this recess sidewalls place.

Because the electric contact piece of socket of the present utility model is positioned at the recess of the jack bottom avris of socket, therefore can't touch the electric contact piece of socket with general conductor, can avoid the electric shock accidents that causes therefrom, have advantage safe in utilization.

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

Fig. 1 is the structural representation of plug among first embodiment of the utility model;

Fig. 2 is the structural representation of socket among first embodiment of the utility model;

Fig. 3 is that the A-A of Fig. 2 is to cutaway view;

Fig. 4 is the structural representation of plug among second embodiment of the utility model;

Fig. 5 is the structural representation of socket among second embodiment of the utility model.

The utility model is made up of plug and socket, as shown in Fig. 1～Fig. 3.

Plug shown in Figure 1 has insulation crust 1 and copper plug electric contact piece 2; The lower end projection of plug electric contact piece 2, the top of this jut is platform, form the inclined-plane below, the flexible electrical conductor 3 of the middle part weld metal sheet of plug electric contact piece 2 or metal wire and so on, metal wiring film 4 welding in flexible electrical conductor 3 and the shell 1 are to realize being electrically connected the end connection terminal screw 7 of lug plate 4; The both sides of plug body 1 bottom have the outwardly directed hole of lower end jut that allows plug electric contact piece 2; The both sides at shell 1 middle part also have the hole, and the button 5 affixed with the upper end of plug electric contact piece 2 is housed in this hole; The spring 6 that touches mutually and the lower end jut of plug electric contact piece 2 is stretched out outside the two side holes of shell 1 bottom with button 5 is housed in the shell 1.

Fig. 2 and socket shown in Figure 3 have insulation crust 8 and copper socket electric contact piece 9; Open vertical jack 11 on the shell 8, jack 11 bottoms are recessed to avris, and formation can be held the recess of the jut of plug electric contact piece 2, and the socket electric contact piece 9 that is connected with terminal screw 10 is fixed in this recess sidewalls place.

Inside pressing keys 5, the lower end jut of plug electric contact piece 2 are just driven inwardly retraction, and plug can successfully insert socket or extract from socket at this moment.After plug insertion socket puts in place, the recess of the jack bottom avris of the proper respective socket of lower end jut of plug electric contact piece 2, unclamp button 5 this moment, the just d/d spring of the lower end jut of plug electric contact piece 2 is pressed to the outside, closely contact with the socket electric contact piece 9 that is fixed in this recess sidewalls place, thereby realized that plug is electrically connected function with the safety of socket.

Consider that from manufacture craft plug electric contact piece 2 also can be made one with button 5.In addition, contact with the good of socket electric contact piece 9,, also can install and touch mutually with the inboard of the jut of plug electric contact piece 2 and by spring that the latter pushed in the bottom of plug body 1 for guaranteeing plug electric contact piece 2.

In second embodiment of the present utility model of Fig. 4～shown in Figure 5, the not perforate of middle part of plug body 1, and save button, its spring 6 is contained in the bottom of said plug body 1, and touch mutually with the inboard of the jut of plug electric contact piece 2, the top and bottom of the lower end jut of plug electric contact piece 2 are the inclined-plane.

In the plug insertion socket or the process of from socket, extracting, the power that the jut of plug electric contact piece 2 lower ends can give because of the sidewall of the jack 11 of jack housing 8 bounces back, after plug insertion socket puts in place, the just d/d spring of the jut of plug electric contact piece 2 is pressed to the outside, closely contacts with the socket electric contact piece 9 that is fixed in this recess sidewalls place.

When vertical use socket, make for preventing because of humid environment and dabbling that water causes short circuit risk in the socket, also have the aperture 12 of sluicing usefulness in the bottom of the jack 11 of above said jack housing 8.
