Abstract
The utility model belongs to the improvement on sockets and plugs in the field of electric production technology and comprises a safety socket and a safety plug. The safety socket is provided with a socket shell 1. An insulation partition block 4 is fixed on a bottom plate of the socket shell 1. Moving contacts 5 that can move right and left are fixed at two sides of the insulation partition block 4 and connected with a bimetallic strip 11. The safety plug is provided with a plug shell 8. A conductive plug rod 10 is connected with a lead and fixed in the plug shell 8. The conductive plug rod 10 is externally sheathed with a movable insulating sheath 9. The utility model has the advantage that by the connection between the moving contacts and the bimetallic strip, the bimetallic strip stretches to the two sides and pulls the moving contacts to draw back in a cylindrical positioning shell from the outside when a circuit is overloaded, and the plug is released from the socket, thus cutting off the power supply of an electrical appliance and achieving the purpose of protecting the electrical appliance.
Description
Technical field
The utility model belongs to electric manufacturing technology field, particularly to the improvement of electric connector and socket.
Background technology
Existing socket is by spring inserted sheet clamping plug, and is more firm behind the plug insertion socket, and still holding circuit is communicated with when circuit runs into high pressure, overload, causes the accident of burning electrical appliance easily.Reed in the socket is exposed to the socket aperture bottom in addition, often has child to insert with conductor such as iron wire and causes electric shock accidents.
Summary of the invention
The utility model purpose provides a kind of safety socket and plug, to overcome the drawback that existing plug and socket can't automatic disconnections when transshipping.
Specifically, safety socket has Socket casing, and it is fixed with the insulation spacer block on the Socket casing base plate, is fixed with the armature contact of left and right displacement in insulation spacer block both sides, and armature contact is connected with bimetal leaf.
Armature contact is fixed on the metal conducting bar, and there is spring on metal conducting bar one end top, and metal conducting bar is positioned in the tubular location shell with spring, and armature contact passes through metal conducting bar, spring is connected with bimetal leaf.Armature contact is circular.Between two armature contacts, be connected to resistance and indicator light.
Safety plug has plug casing, and the conductive plug bar is connected with lead and is fixed in the plug casing, is with movable insulating sleeve outside the conductive plug bar, the through hole that movable insulating sleeve bottom has the conductive plug bar to stretch out.
Movable insulating sleeve is inner to be connected with coil tension spring, and coil tension spring is fixed in the plug casing.Conductive plug bar bottom sides is shaped on circular groove and is convenient to cooperate with circular armature contact.
The utility model advantage is to be connected with bimetal leaf by armature contact; bimetal leaf opens the pulling armature contact to both sides and outwards withdraws in the shell of tubular location when overload in circuit; plug deviates to disconnect the electrical appliance power supply from socket, reached the purpose of protection electrical appliance.In addition, cooperate by armature contact and insulation spacer block and to have sealed most of jack mouth, simultaneously by insulating sleeve with the conductive plug rod seal, stopped the generation of error shock accident.

Embodiment
Provided the utility model embodiment as Fig. 1, Fig. 2.Safety socket such as Fig. 1 have Socket casing 1, are fixed with insulation spacer block 4 on the Socket casing base plate, are fixed with the armature contact 5 of left and right displacement in insulation spacer block 4 both sides, and armature contact 5 is connected with bimetal leaf 11.Armature contact 5 is fixed on the metal conducting bar 6, and there is spring 3 on metal conducting bar 6 one ends tops, and metal conducting bar is positioned in the tubular location shell 2 with spring, and armature contact 5 passes through metal conducting bar, spring is connected with bimetal leaf 11.Armature contact 5 for conductive plug bar bottom sides in circular and the safety plug be shaped on circular groove cooperate locate more firm.Be connected to resistance R and indicator light L between two armature contacts 5.By being set, indicator light can judge in the socket whether switch on.For multipurpose socket, described armature contact multiple row is arranged.
Safety plug as shown in Figure 2, it has plug casing 8, conductive plug bar 10 is connected with lead and is fixed in the plug casing 8, is with movable insulating sleeve 9 outside conductive plug bar 10.Movable insulating sleeve 9 the inners are connected with coil tension spring 7, and coil tension spring is fixed in the plug casing 8.Conductive plug bar bottom sides is shaped on circular groove.
The utility model operation principle: coil tension spring is compressed during with plug insertion socket, movable insulating sleeve moves up, the conductive plug bar stretches out movable insulating sleeve and inserts socket aperture, and armature contact snaps in the circular groove of conductive plug bar side, simultaneously compacted location under the effect of spring.In case circuit overloads, bimetal leaf expand and to open the pulling armature contact to both sides and outwards withdraw in the shell of tubular location, plug deviates to disconnect the electrical appliance power supply from socket, reached the purpose of protection electrical appliance.
