Abstract

The utility model relates to shock-proof anti-loose safety plug and socket. The device includes a plug; one end of the insulating plug is fixed to metal tabs; the other end is a supply lead; the appearance surface of the metal tabs is equipped with a concave shaped insulated peel; an opening section of the insulated peel of the metal tabs is nude; the opening section of the insulated peel is positioned between the metal tabs. The device also includes a socket; the socket is provided with a hub corresponding to the metal tabs and the insulated peel; the socket in the hub is fixed with metal connecting pieces; the connecting pieces are provided with a boss corresponding to a groove of the metal tabs so as to electrically contact with the tabs. The device is safe and reliable; the contact between the plug and the socket is firm; moreover, bad contact phenomenon between the electrical equipment and the power supply doesn't occur.

Description

The anti-loosening safety plug socket of protection against electric shock

(1), technical field

The utility model relates to the anti-loosening safety plug socket of a kind of protection against electric shock.

(2), background technology

The inserted sheet of the used plug of electric equipment in the market all exposes, and this brings very big inconvenience and dangerous for child and blind person's use, and the phenomenon of getting an electric shock in plug plug process happens occasionally.Also have the plug that uses now not firm owing to contacting, cause the power supply loose contact, cause the damage electric equipment with socket.

(3), summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of protection against electric shock anti-loosening safety plug socket, and it is safe and reliable, and plug contacts with socket firmly, can not cause electric equipment power supply loose contact phenomenon.

The technical scheme in the invention for solving the technical problem is: it comprises plug, one end fixing metal inserted sheet of the plug of insulation, the other end is a power supply lead wire, described metal insert outer surface has " recessed " font insulated hull, metal insert is exposed at the opening portion of insulated hull, the inboard of the aperture position of described insulated hull between metal insert;

It also comprises socket, has on the socket and described metal insert and the corresponding jack of insulated hull, and fixing metal contact pin on the socket in the jack, metal contact pin has and the corresponding boss of described metal insert groove, so that electrically contact with inserted sheet.

In order to make plug, socket contact firmly, there is spring leaf on the metal contact pin opposite on the described socket.

Because metal insert does not expose, so safe and reliable.Because plugs and sockets is the convex-concave contact, and has spring leaf to compress, so plug contacts with socket firmly, can not cause electric equipment power supply loose contact phenomenon.

(4), description of drawings

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

Fig. 1 is the utility model plug partial sectional view;

Fig. 2 is the A-A cutaway view among the utility model Fig. 1;

Fig. 3 is the utility model socket partial view;

Fig. 4 is the B-B cutaway view among the utility model Fig. 3.

(5), embodiment

As shown in Figure 1, 2, an end fixing metal inserted sheet 2 of the plug 1 of insulation, the other end is a power supply lead wire.Described metal insert 2 outer surfaces have " recessed " font insulated hull 3, and metal insert 2 is exposed at the opening portion of insulated hull 3.The inboard of the aperture position of described insulated hull 3 between metal insert.Described insulated hull 3 is detachable with metal insert 2, so that the existing supporting use of socket.

Shown in Fig. 3,4, have on the socket and described metal insert 2 and insulated hull 3 corresponding jacks 6, fixing metal contact pin 7 on the socket 4 in the jack 6, metal contact pin 7 has and the corresponding boss of the groove of described metal insert 2, so that electrically contact with inserted sheet 2.In order to make plug 1, socket 4 contacts firmly, there is spring leaf 5 on metal contact pin 7 opposites on the described socket 4.

Claims
