Abstract

The utility model relates to a power source and the socket and the rotary plug of an electrical appliance. A socket casing is an inner circle hollow body molded in a whole. The rotary plug is a cylinder whose upper part is small and a lower part is big. The rotary plug is inserted into the socket casing. If the rotary plug rotates in a certain angle, circular arc-shaped bosses arranged on both side faces in the lower part of the plug are exactly clamped by clamp blocks arranged on both side faces in the socket. Thereby, the plug can not fall off due to pull. A conductive sheet connected to the plug is closely contacted with a conductive contact sheet fixed in the socket. The utility model has the advantages of reliable electric contact, assurance of non-heating of the plug, long service life, simple structure, and safe utilization.

Description

Power supply and electrical appliance socket/rotary connector
The utility model relates to a kind of socket/, more specifically say so a kind of power supply and electrical appliance socket/.
The socket/that is used for power supply and electrical appliance at present, generally all be that plug is directly inserted energized in the socket, after this class socket/is used a period of time, plug gets loose easily, when plug and socket loose contact, easily make conductive contact blade produce oxidation, thereby cause the plug heating, even burn plug.
The utility model purpose is to provide a kind of pulling power-line plug also can not come off, and socket and plug electrically contacts reliably, and head is broadcast in the power supply of long service life and electrical appliance socket/rotation.
Power supply provided by the utility model and electrical appliance socket/rotary connector mainly are made up of Socket casing and rotary connector body two parts, the internal circular hollow body that Socket casing is formed in one, on the opposite position of the two sides, top of internal circular hollow body, respectively be provided with a fixture block, being contained in the outer binding post of Socket casing passes housing and fixedlys connected with fixture block respectively, socket T shape conductive contact blade is connected on the binding post that passes housing, power line be contained in the housing outer terminal and be connected; The rotary connector system is become cylinder, arc cam is made in the two sides of its underpart, the plane is processed in two sides in addition, the plug conducting sheet is separately fixed on the circular arc projection of plug body bottom, power line links to each other with the plug conducting sheet, rotary connector is inserted in the Socket casing, and then turn an angle, make that the T shape conductive contact blade in the conducting strip and socket closely contacts on the plug, this moment, the arc cam of rotary connector bottom was blocked by fixture block set in the socket, pull the power line on the plug in any case, plug can not come off yet.
The utility model directly inserts existing plug the mode of socket energising, change the energising of plug rotary extrusion type into, thereby guarantee that plugs and sockets closely contacts, it conducts electricity very well, plug can be removed the oxide layer on conducting strip surface in rotation, guarantee reliable electrical contact.In use plug does not generate heat, and can not burn yet, because the arc cam on the plug is stuck by the fixture block of socket, therefore pulls plug in any case and can not come off, and it also has simple in structure, and is easy to use, safe and reliable characteristics.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1--be the vertical view of the utility model socket.
Fig. 2--be the A-A face cutaway view of Fig. 1.
Fig. 3--be overlooking of the utility model rotary connector.
Fig. 4--be the B-B face cutaway view of Fig. 3.
As shown in Figure 1 and Figure 2, Socket casing 1 insulating material one-shot forming provided by the utility model, be the circle hollow body in it, the shape of shell body is square, oval, rectangle etc., be contained in Socket casing 1 outer binding post 3 and pass housing, socket T shape conductive contact blade 4 tops are connected on the binding post 3 that passes housing 1, and both sides, socket T shape conductive contact blade 4 bottom embed in the housing 1.Fixture block 2 set on the opposite position of two sides, internal circular hollow body top tightens together with binding post 3, earth terminal 14 is equipped with in bottom outside Socket casing 1, with reference to Fig. 3, Fig. 4, it is cylinder that rotary connector body 5 adopts the insulating material one-shot forming, the diameter that should make its underpart is greater than upper diameter, have metallic channel 13 at the cylinder center, plane 8 is made in the two sides of rotary connector body 6 bottoms, make other two sides become arc cam 6, plug conducting sheet 7 is fixed on the arc cam, power line is connected with plug conducting sheet 7 by metallic channel 13, in order to insure safety, the utility model is inserted in set band step safety guard 10 on the plug body 5 and is stuck on the arc cam 6, on the top of broadcasting a body 6 Spring Card 12 is housed, spring 11 is connected between band step safety guard 10 and the Spring Card 12, during use, rotary connector is pushed along the socket inner housing, this moment, safety guard 10 was blocked by the set fixture block 2 in Socket casing top, safety guard 10 is stuck in the top of Socket casing 1, continue to advance plug to the socket bottom, and then plug turned an angle, T shape conductive contact blade 4 in conducting strip 7 and the socket on the plug is closely contacted, power supply is switched on, this moment, the arc cam 6 of rotary connector bottom was blocked by the fixture block in the socket 3, so power line on the pulling plug of putting forth one's strength, plug can not come off, and earth connection 9 is equipped with in rotary connector of the present utility model bottom.
