Abstract

The invention relates to a power supply socket and plug for low-voltage electrical-equipment. The socket and plug comprises an insulated socket body (1) and an insulated socket box (2), wherein the insulated socket body (1) is fixed on the electrical equipment; the insulated socket box (2) is in inserting connection with the insulated socket body (1); the insulated socket body (1) is provided with a two-phase or three-phase electrode guide post (3) and an iron block (4); and the insulated socket box (2) is internally and correspondingly provided with a two-phase or three-phase electrode shrapnel (5) and a magnet (6). When the plug power line of the plug is entangled or pulled, the plug can quickly and easily fall off from the socket, so as to avoid pulling down the electrical equipment fixedly connected with the socket, so that the damage of people or the electrical equipment can be prevented.

Description

A kind of magnetic socket, plug

Technical field

The present invention relates to a kind of supply socket, plug of low-voltage electrical apparatus.

Background technology

The power supply connection device of common low-voltage electrical apparatus is divided into two kinds: a kind ofly comprise a power line; One end connecting circuit inside conductor of power line; The other end is provided with plug, and plug is provided with electrode, and plug is pegged graft into commercial power socket; The electrode intermediate plate of commercial power socket grasps plug electrode, can be communicated with power supply; Another kind is split type, comprises a socket and a plug, and socket is installed on the electrical equipment, is provided with inserting groove and electrode column in the socket, wherein, and electrode column connecting circuit lead; Be provided with spliced eye in the plug, be provided with electrode slice in the spliced eye, electrode slice is electrically connected with the city through power line; In the inserting groove with plug insertion socket, meanwhile, electrode column also inserts in the spliced eye of plug, and electrode column and electrode slice are in contact with one another, and so both can be communicated with power supply, can socket be connected fixing again with plug.

But above-mentioned any power supply connection device no matter, with plug insertion socket, be communicated with civil power after, all exist a potential safety hazard: because between the socket and plug or through the intermediate plate method of clamping; Or realize connecting fixing through the mode of slotted eye driving fit; Therefore, the two interlock is very tight, in case the people stumbles or pull power cord plug because of carelessness; Just might pull electrical equipment and fall to the ground, thereby people and electrical equipment are damaged.

Summary of the invention

To existing socket, the existing the problems referred to above of plug, the invention provides a kind of when the people tears power cord plug because of carelessness, can let socket and plug rapidly, the magnetic socket, the plug that separate like a cork.

The present invention has taked following technical scheme to realize above-mentioned purpose:

A kind of magnetic socket, plug comprise an insulated receptacle body and an insulated receptacle box, and the insulated receptacle body is fixed on the electrical equipment, and the blind plug box is plugged on the insulated receptacle body; The insulated receptacle body is provided with two phase or three-phase electrode guide pillar and iron blocks, correspondingly is provided with two phase or three-phase electrode shell fragment and magnet in the blind plug box, wherein:

The rear end of electrode guide pillar is electrically connected through the circuit in lead and the electrical equipment, and the rear end of electrode shell fragment is passed through power line and is electrically connected with civil power, is in contact with one another through the contact of front end separately between electrode guide pillar and the electrode shell fragment to be communicated with conduction;

Iron block is fixed on the center of insulated receptacle body, and between the electrode guide pillar, magnet is fixed on the center of blind plug box, and between the electrode shell fragment, the two is fixed insulated receptacle body and blind plug box through magnetic attraction each other.

Above-mentioned a kind of magnetic socket, plug, the insulated receptacle box can adopt integral structure, also can adopt the split-type structural that comprises end box and lid.

The invention has the beneficial effects as follows: because connection between the socket and plug and fixing main interior iron plate of socket and the mutual attraction between the magnet in the plug of relying on realize; So in case power cord plug is stumbled, pulls by the people; Plug can be rapidly, split away off from socket easily; So just can avoid pulling and be connected fixing electrical equipment with socket, thereby prevent people or electrical equipment are damaged.
