Abstract

The utility model relates to the technical field of plugs and sockets, in particular to a separated plug and socket; the utility model comprises a plug and a socket which are used together; iron sheets and magnets are respectively fixed on the bonding surfaces of the socket and the plug; when the iron sheets and the magnets are attracted, the electrode of the socket and the conductive splinter of the plug contact; because the iron sheets are mutually attracted in a magnetic field, the connection of the plug and the socket can ensure the stable connection; in addition, a certain pressure exists between the electrode and the conductive splinter because of magnetic absorption, so the stability of a circuit can be ensured; the socket and the plug can be separated without too large external force because of the magnetic absorption, so the use is very convenient; in addition, an anti-reverse plugging structure is adopted, to ensure safe power consumption.

Description

Split type plugs and sockets

Technical field:

The utility model relates to the plugs and sockets technical field, particularly split type plugs and sockets.

Background technology:

General thermostat plug and thermostat socket, their connections between the two realize (power supply connects and temperature control partly is an one) by welding or clamping.UL standard security standard according to the U.S., in using the liquid heat process, must possess break function between electrical appliance and power line, promptly when touching power line, touching the external force that is produced must separate power connector in a certain scope with electrical appliance, to avoid electrical appliance to topple over or drop, cause breakage or electric leakage, human body is damaged.

More existing sockets, it between the electrode of its heating part and the socket (power supply is connected and temperature control partly is an one) movable plug-in type, the electrode of this heating vessel is cylindric and contacts with the lotus shape sleeve, be called the one contact, this product is when meeting accident, heating part can not separate timely with power line socket, makes electrical appliance topple over or drop, and causes breakage or electric leakage that human body is damaged.The socket of this structure uses in the vessel that use liquid heat has unsafe defective.

The utility model content:

The purpose of this utility model is to provide split type plugs and sockets at the deficiency of existing thermostat, and it both can guarantee that plug well contacted with socket, and the while can also be realized separating of plug and socket more conveniently.

For achieving the above object, the utility model adopts following technical scheme:

It comprises plug, the socket that is used, and the composition surface of socket and plug is fixed with iron plate, magnetic iron plate respectively, and iron plate just can make the electrode of socket contact with the electroconductive elastic sheet of plug during with the adhesive of magnetic iron plate.

Form on the composition surface of described socket for the ccontaining inner fovea part of plug head, iron plate is fixed in the bottom of this inner fovea part.

Offer electrode hole on the composition surface of described plug for the electrode insertion of socket.

The electrode of described socket is positioned at the inner fovea part of socket.

The bottom of described inner fovea part forms projection, and plug head has the counnter attack that cooperates with projection and inserts the Access Division, and projection cooperates with the slotting Access Division of counnter attack and plays the counnter attack plugging function.

The beneficial effects of the utility model are, because iron plate attracts each other under the effect in magnetic field, therefore, during with plug and socket grafting, can guarantee both stable connections; In addition, utilize the magnet suction type to make between electrode and the electroconductive elastic sheet and have certain pressure, so can guarantee that circuit is stable; Adopt the magnet suction type, do not need too big external force just can realize the separation of socket and plug, very easy to use, but also adopt protective design to avoid insterting by mistake, the assurance Electrical Safety.

Description of drawings:

Fig. 1 is a structural representation of the present utility model

Embodiment:

Below in conjunction with accompanying drawing the utility model is further described.

See accompanying drawing 1, the utility model comprises plug 20, the socket 10 that is used, and socket 10 is fixed with iron plate 18, magnetic iron plate 24 respectively with the composition surface of plug 20, and iron plate 18 is just in time corresponding mutually with the position of magnetic iron plate 24; Iron plate 18 just can make the electrode 16 of socket 10 contact with the electroconductive elastic sheet 22 of plug 20 during with 24 adhesives of magnetic iron plate, because iron plate 18 attracts each other with magnetic iron plate 24, therefore, when plug 20 is pegged graft with socket 10, can guarantee that both are stable to connect; In addition, adopt the mode of magnet absorption, on direction up and down, do not need too big external force just can realize separating of socket 10 and plug 20, when the user runs into the power line of plug 20 because of carelessness, plug 20 is separated with socket 10, so just can not make electrical appliance be involved together and damage electrical appliance or injury user.

In order to make socket 10 and plug 20 when interconnecting, guarantee Electrical Safety, also can adopt following structure: form on the composition surface of described socket 10 for the ccontaining inner fovea part 12 of plug 20 front ends, iron plate 18 is fixed in the bottom 14 of this inner fovea part 12, when this structure can guarantee that plug 20 is connected with socket 10, electrode can not be exposed outside, and guarantees Electrical Safety.

In order to strengthen fail safe, offer electrode hole 26 on the composition surface of described plug 20, the electrode 16 on the electroconductive elastic sheet 22 of plug 20 and the socket 10 is just in time corresponding mutually; Electrode 16 1 ends of described socket 10 are positioned at socket 10, the other end is positioned at inner fovea part 12, the electroconductive elastic sheet 22 of plug 20 is positioned at plug 20 fully, when plug 20 engaged with socket 10, the electrode 16 on the socket 10 can penetrate in the electrode hole 26 on the plug 20 and contact with the electroconductive elastic sheet 22 of plug 20.

The bottom 14 of described inner fovea part 12 forms projection 30, plug 20 front ends have the counnter attack that cooperates with projection 30 and insert Access Division 40, when plug 20 forwards insert in the inner fovea part 12 of socket 10, projection 30 falls in the Access Division 40, if when the inner fovea part 12 of socket 10 is inserted in plug 20 upsets again, projection 30 no longer with Access Division 40 coordinations, so electrode 16 is non-conductive, thereby realize the counnter attack plugging function.

Socket 10 shown in the figure adopts two electrodes, and iron plate 18 is between two electrodes 16 of socket 10, and the front end that plug magnetic iron plate 24 is positioned at plug 20 is corresponding with iron plate 18.

The utility model both can guarantee that plug well contacted with socket, can also realize simultaneously separating of plug and socket more conveniently.
