Abstract

The utility model discloses a magnetic safety power supply plug and a socket belonging to electric components. The utility model is composed of a plug and a socket. The socket is composed of a socket body and a socket cover. A round iron, a spring and a contact head draw rod are arranged in the socket body. A magnet is arranged in the plug. When the plug is inserted in the socket, the magnet on the plug attracts the round iron to drive the contact head draw rod to move, a contact is closed, and the electricity is communicated. The utility model has the advantages of simple structure, easy fabrication and high safety. The magnetic safety power supply plug and the socket of the utility model can avoid the accident of electric shock when either a metal strip or a magnet is inserted in the socket.

Description

Magnetic safety power supply plug and socket

The utility model belongs to a kind of electric components.

Present widely used plug and socket of power source has following several types:

1. round, the circular hole of square, flat spring hole scoket and round end, tack plug;

2. position-sensing switch formula socket;

3. multiple protective seals safety socket automatically;

More than the 1.2 two kind of plugs and sockets all less than thoroughly solving the security insurance problem, when child uses, the electric shock phenomenon takes place easily particularly.Though the 3rd kind has solved safety problem, its complex structure, the cost height is made difficulty.

The purpose of this utility model provides a kind of safe and reliable, makes simple magnetic-type safety powr supply plug and socket.

Description of drawings: Fig. 1, magnetic-type safety power source plug socket structure chart.

Fig. 2, magnetic-type safety powr supply plug structure chart.

With reference to the accompanying drawings, the utility model is elaborated

Magnetic-type safety powr supply plug of the present utility model and socket have changed the structure of original various plugs and socketss, and its socket is by (15) two most of compositions of socket (14), socket cover.On socket (14), have a square jack (5), its size is supporting with plug.Switch lever (2) is passed the circular hole on the socket (14), and an end is fixed with round iron (1), and the other end is equipped with spring (3).One end of contact pull bar (4) is installed on the switch lever (2), and the other end links to each other with power supply contact (7).Contact lever (6) is fixed on the socket (14), and the one end is connected with contact (8) by connector, and the other end is unsettled in jack (5).See shown in the figure one.At plug body (13) middle part one magnet/(12) are housed, front end is equipped with a contact flat spring (11), and a spring (10) is equipped with in the lower end of contact flat spring (11), links to each other with contact flat spring, and an end of lead (9) is connected on the contact flat spring (11).See shown in the accompanying drawing two.During use, in the square hole with plug insertion socket, magnet (12) just in time produces suction to round iron (1), and round iron (1) is moved down, and drives contact pull bar (4) and moves down, double-contact contact (8) closure, thereby make contact lever (6) charged, at this moment, contact flat spring contacts with contact lever (6), entire circuit is connected, operate as normal.

Magnetic-type safety powr supply plug of the present utility model and socket are compared with existing various plugs, socket, and it is low to have a cost, and security performance is good, are to insert the generation that socket can not cause electric shock accidents with bonding jumper or magnet.
