Abstract

The utility model relates to a safety socket. The utility model adopts an electric interlock which is composed of a rotatable rocker and a contact piece uncharged in general. When a metal conductor is inserted into any jack of the socket to contact with the contact piece, the inserted conductor isn't electrified. Only when the two pin of a plug of an electrical appliance are inserted into the jacks, can the electrical appliance be supplied. Consequently, the electric shock or the casualty caused by electric shock can be prevented when the metal conductor is inserted into the jack by mistake.

Description

Safety socket

The utility model relates to a kind of two pole sockets that are used for single phase poaer supply.

General supply socket mainly is made up of socket, contact chip, binding post and cover plate.It is promptly charged for a long time that its contact chip of back is installed.Because charged contact chip is exposed in the jack, (1) causes children to insert, play jack and the injures and deaths that shock by electricity or get an electric shock with metal objects easily; (2) if one pin is still stayed in the jack during unplugg, also can get an electric shock.

In order to prevent to get an electric shock, a kind of socket with emergency exit is arranged at present, it is to have increased the screening orifice plate on original socket, avoids charged contact chip directly to expose, but the not solution of contact chip Issues on Static Electrification, electric shock accidents still can take place.

The purpose of this utility model just provides the not direct charged safety socket of a kind of contact chip, to stop the generation of accident.

The utility model is realized by this way: when a metallic conductor inserts arbitrary jack of this socket, fork is rotated around a center, the fork bottom promotes the contact chip under another jack in rotation, make this contact chip contact energising with binding post.In this process, although metallic conductor has inserted jack and contacted with contact chip, as long as do not insert any object in another jack, this metallic conductor all the time can be not charged.Have only two pins all to insert socket, could power to electrical appliance when the electrical appliance plug.As seen the utlity model has reliable electroshock-proof function.

Accompanying drawing is a concrete structure of the present utility model.

Fig. 1 is the cutaway view of structure; Fig. 2 is the movement state diagram behind the insertion plug.

With reference to Fig. 1, two energy are fixed on the socket ［ 7 ］ around fork ［ 3 ］, ［ 5 ］ that garden pin ［ 4 ］ rotates, and fork ［ 3 ］, ［ 5 ］ are plastic pressing forming, should have the good insulation performance performance, and enough intensity and resistance to wear should be arranged.Socket ［ 7 ］ also is the plastics rolled-up stock, has higher insulation property, and in order to simplify assembly technology, socket ［ 7 ］ adopts symmetrical part composite construction, and socket ［ 7 ］ is provided with three boss arranging by " product " font.Contact chip ［ 2 ］ and ［ 6 ］ are stuck in three boss, and its top is by bending.And the garden of vertically the being processed into arc of dogleg section.Be beneficial to and the cooperating of multiple appliance plug ［ 9 ］; Its underpart dashes a little sphere, guarantees to contact with binding post ［ 1 ］ or the good of ［ 8 ］, and this sphere and binding post ［ 1 ］ or ［ 8 ］ keep certain interval.For guaranteeing the functional reliability and the useful life of socket, adopt contact chip ［ 2 ］ and ［ 6 ］ has satisfactory electrical conductivity and flexible material.

The utility model compared with prior art has the advantages such as security performance is more reliable, process structure is reasonable. And production cost and existing product are substantially approaching.

Claims

1, a kind ofly it is characterized in that being equipped with in the socket fork and garden pin by molecular single-phase two utmost point supply sockets of cover plate, socket, contact chip and terminals, fork can rotate around the garden pin, and the contact chip that promote simultaneously another jack under contacts binding post.

2, according to claim item 1 said socket, it is characterized in that said socket adopts two symmetrical part composite constructions, the boss of arranging by " product " font is arranged on the socket.

3, according to claim item 1 said socket, it is characterized in that said contact chip is to be stuck in " product " font boss of socket, bottom sphere and binding post are gapped.
