Abstract

The utility model discloses a power supply socket and plug, wherein a plug is provided with a plug post, one end of the plug post is connected with a wire connecting terminal which is provided with an insulation layer and a conducting wire rabbet, and one end of the wire connecting terminal near the plug post is provided with an outward protrusion which can prevent the plug post from dropping out of the socket. The socket is provided with an insulating casing which is provided with a row of rabbets, the upper end of each rabbet is provided with a flute which is provided with a notch and is matched with the outward protrusion of the plug, and the rabbet is provided with an intubation tube in which the plug post can be inserted, and the intubation tube is communicated with a power supply. One plug of the utility model can only be connected with one conducting wire, so the utility model has the advantage of flexible use and can also be inserted with multiple conducting wires according to the requirements of electric devices, therefore the utility model has good commonality. The utility model has the advantages of light weight and small size, the insulating layer on the plug is not easy to be damaged, the insulating layer can be replaced when damaged and can not affect other plugs, therefore the utility model can effectively reduce maintenance cost.

Description

Supply socket and plug

Technical field:

The utility model relates to a kind of supply socket and plug.

Background technology:

Present known attaching plug all is made up of two to four inserting columns and the shared shell of each inserting column.The then corresponding design of socket with plug, between do not have interchangeability, the only corresponding a kind of socket of a kind of plug.And present this plug is because shell is that each inserting column is shared, so volume is big, is easy to be broken, especially the plug that uses of factory or construction site, because cable (rubber-covered) is more big and heavy, when pulling up plug and arbitrarily loose one's grip, the shell of plug will be fallen on the ground heavyly and be smashed; When moving the lead of band plug, also can be owing to the plug volume is hung bad greatly easily.This phenomenon makes repair cost high owing to occur too frequently, and the clear-cut jack that directly cable is inserted socket of people compresses with some little peg woods sometimes, and certain this way is absolutely unsafe, especially for multi cord.Present in addition known socket is to the connection of power supply, employing all be internal connecting type, the locus that the special purpose interface of other socket of not connecting, line difficulty and this socket occupy during a plurality of arranging in distribution box is bigger.

The utility model content:

It is good that the utility model aims to provide a kind of versatility, non-damageable supply socket of plug body and plug.

The technical scheme that the utility model is taked is: plug has an inserting column, and an end of inserting column is connected with the binding post of tape insulation layer and wire jack, and described binding post is provided with the evagination that prevents the inserting column separation connector by an end of inserting column.

The utility model socket has an insulation crust, and this has jack above shell, and the jack upper end is provided with a notched groove that matches with the plug evagination, is the intubate that is used for inserting inserting column in the jack, and intubate is communicated with power supply.

For easy-to-connect, and be convenient to closely arranging of many sockets uses, socket insulation crust both sides are provided with binding post, and the bottom of described intubate is connected with a conducting strip, and these conducting strip both sides extend described binding post.

The utility model plug available different color mark live wire, ground wire, zero line on its insulating outer layer when making.During use; a plug only connects a lead; when it being inserted on the utility model socket; with the breach on the evagination alignment socket on the plug; make evagination fall into described groove, rotary connector is stabilized in the socket plug then; can not become flexible, the stabilizing equipment power supply is had very positive meaning.Because a plug only connects a lead, very flexible during use, if socket is a Three-phase five-wire, we can insert in the corresponding receptacle sockets according to demand or Three-phase five-wire or three-phase and four-line or the single-phase three-wire or the single-phase two wires etc. of power consumption equipment, as long as be no more than the load rating electric current, need to insert several and just insert several, a socket has just solved all kinds of needs for electricity, thereby the utlity model has good versatility, and commutation is very convenient.Lighter owing to plug weight in addition, volume is less, thereby the insulating barrier on the plug is difficult for breaking or it is bad to be hung, and has promptly given a piece of bad advice one, also only need change one, does not influence other plug, and maintenance cost is effectively reduced.

Description of drawings:

Fig. 1 is the structural representation of the utility model plug.

Fig. 2 is the structural representation of the utility model socket.

Fig. 3 is that the A of Fig. 2 is to view.

Embodiment:

Present embodiment is an example that is used for the three-phase five-wire mode power supply.The utility model plug has a cylindrical inserting column 1 as can be seen from Figure 1, one end of inserting column 1 is connected with binding post 2, binding post 2 has insulating barrier 3 and wire jack 5, insulating barrier 3 and is provided with an evagination 4, one line ball bolts 21 by an end margin of inserting column and passes described insulating barrier 3 and enter wire jack 5 lead is compressed.

Fig. 2 and Fig. 3 have reflected the detailed structure of the utility model socket, from Fig. 2 and Fig. 3 as can be seen the utility model socket have an insulation shell 6, this insulation shell is provided with jack 7, the upper end of this jack is provided with recessed towards periphery groove 8, the groove end face is provided with breach 9, make on the utility model plug evagination thus breach enter groove 8.The two sides of insulation shell 6 also respectively are provided with a binding post 13, one conducting strip 10 is arranged between two binding posts 13, one intubate 11 is arranged in the jack 7 of insulation shell, and intubate 11 lower ends link to each other with conducting strip 10, and lead inserts binding post 9 makes lead well contact with conducting strip 10 by wiring spiral shell card 12.Intubate 11 is with charged after the lead energising.The bottom of socket can be pick-uped bar some sockets are fitted together, or with screw socket is fixed on the distribution panelboard.

The utility model socket is except making the described single form of example (Three-phase five-wire or three-phase and four-line or single-phase three-wire or single-phase two wires), also can be made into a plurality of forms that are connected as a single entity, just conducting strip 10 lengthenings are a little, and two binding posts 13 are still at the two ends of conducting strip 10.

Another execution mode of the utility model socket is only the upper end of jack to be provided with the described groove 8 that has breach 9 on the basis of existing socket, it can be used with the utility model plug get final product.

Plugs and sockets of the present utility model has matching relationship, and the one, evagination on the plug and the groove fit on the socket are used; The 2nd, the inserting column of plug and the intubate of socket cooperatively interact, plug can insert any one jack and the intubate that is no more than the rated current socket as required, during the jack of plug insertion socket, should note breach with its evagination elder generation alignment receptacles upper end, rotate an angle again after entering groove, plug steadily is inserted on the socket not can loose or dislocation, angle of counter-rotating when taking off plug, make evagination face toward indentation, there and pull up plug again, whole use can guarantee that Electrical Safety is stable.The utility model is applicable to the socket plug docked mode of all kinds of power supplys, as Three-phase five-wire, three-phase and four-line, two-phase two wires, single-phase three-wire and single-phase two wires.Because each plug only connects a lead, weight alleviates relatively, and each plug can not land simultaneously during unplugg in addition, thereby the external insulation layer of plug is difficult to break, and guaranteed that thus Electrical Safety is stable in the whole use, and maintenance cost reduces.
