Abstract

The utility model relates to a plug seat component for a power plug. An annular insulation protection cover is provided at the front end of the plug, all conducting pins are enclosed and covered from the side surface of the annular insulation protection cover, and the shape of a plug seat is matched with the shape of the plug annular insulation protection cover. The utility model is characterized in that the cross section of each pin of the plug is cylindrical or annular, the shape of each plug jack of the plug seat is an annular groove or a cylindrical hole respectively matched with the corresponding annular pin or the cylindrical pin. The plug seat can avoid the electric shock and the problem of the difficult plug of the plug, and the plug seat is not existed, the connection among electric appliances is convenient, for example, the plug seat component can be applied to the power connection between the kettle body of a split electric kettle and a kettle seat.

Description

A kind of plug and socket of power source assembly

The utility model belongs to a kind of power connector, is specifically related to a kind of plug and socket of power source assembly.

The common power plug can be inserted into conductive base pin in the receptacle sockets front end setting, and when plug has just inserted socket but pin when still having a segment length to be exposed at outside the jack, people's finger might touch charged pin from the side, has the danger of getting an electric shock.In order to overcome this shortcoming, 93202965.5 and No. 96219446.8 Chinese patents disclose two kinds of safety-type plug and socket components respectively, be provided with an annular insulating shield in their plug head, from the side all conductive base pins are covered, surrounded, at their sockets annular groove or plush copper with above-mentioned annular insulating shield form fit are arranged, like this when plugs and sockets does not plug together fully, conductive base pin is surrounded by the enclosure space that the clamping of socket and plug annular insulating shield forms, and can avoid taking place electric shock accidents.But above-mentioned plugs and sockets should use and have difficulties, because when pin is about to be inserted into jack, operator's sight line is blocked by annular insulating shield, can't see pin and jack, is difficult to make each pin to aim at corresponding jack respectively, inserts difficulty.

The purpose of this utility model is to provide a kind of plug and socket of power source assembly, and it can prevent from when plugs and sockets from not plugging together fully electric shock accidents to take place, and can make the easy alignment receptacles of pin again.

Its purpose can realize by following scheme: this plug and socket component comprises the plug that has two or two above conductive base pins, and the socket that has the respective numbers jack, jack is built-in with elastic electric conductor, plug head has an annular insulating shield, from the side all conductive base pins are surrounded, cover, the shape of socket and plug annular insulating shield coupling, both can be overlapped mutually, its main feature is, the cross section of each root pin of plug is circular, and constitute concentric circles with the cross section of annular insulating shield, wherein being positioned at middle pin is cylindrical or annular, all the other pins are annular, and the shape of each jack of socket is respectively toroidal cavity or the cylindrical hole that mates with corresponding circle annular pin or cylindrical pin.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is the plug shape schematic diagram of a kind of concrete enforcement structure of the utility model.

Fig. 2 is the socket shape schematic diagram that mates with plug shown in Figure 1.

Fig. 3 is Figure 1A-A line cutaway view.

Fig. 4 is Fig. 2 B-B line cutaway view.

Fig. 5 is second kind of concrete plug shape schematic diagram of implementing structure of the utility model.

Fig. 6 is the socket shape schematic diagram that mates with plug shown in Figure 5.

Fig. 7 is the third concrete plug shape schematic diagram of implementing structure of the utility model.

Fig. 8 is the socket shape schematic diagram that mates with plug shown in Figure 7.

Fig. 1, plug shown in Figure 3 have three pins 121,122,123, there is an annular insulating shield 11 the front end side of plug, from the side three pins are surrounded, cover, wherein middle pin 121 is cylindrical, all the other two pins 122,123 are annular, the cross section of annular insulating shield 11 and Ge Gen pin all is circular, and they constitute concentric circles.Fig. 2, socket shown in Figure 4 have three jacks 221,222,223, the position of each jack, shape three pins with plug shown in Figure 1 respectively are corresponding, it is cylindrical wherein to be positioned at middle jack 221, all the other two jacks 222,223 be shaped as toroidal cavity, be provided with elastic conduction contact 23 in each jack, socket upper portion side wall 21 also is annular, annular insulating shield 11 couplings of its size, shape and plug.In the time plugs and sockets will being plugged together, need only make the annular insulating shield alignment socket annular sidewall of plug, the corresponding jack of the just automatic alignment socket of each pin of plug.

Shown in Figure 5 is a plug that has three pins, and each root pin 121,122,123 shape all is an annular; Shown in Figure 6 is with Fig. 5 in the matching used socket of plug, it has three jacks 221,222,223, the shape of each jack all is a toroidal cavity.

Shown in Figure 7 is a plug with two pins, and the pin 121 in the middle of wherein being positioned at is for cylindrical, and another root pin 122 is an annular.Shown in Figure 8 is and the matching used socket of Fig. 7 plug, and wherein Zhong Jian jack 221 is a cylindrical hole, and another jack 222 is a toroidal cavity.

Certainly, in above-mentioned concrete enforcement structure, socket also can be provided with annular insulating shield 11 couplings of annular groove and plug, and when plugs and sockets plugged together, annular insulating shield was inserted in the annular groove.

The utlity model has following advantage and effect:

1, when plug has just inserted socket, pin and still has a segment length to be exposed at outside the jack, inserts The annular insulating shield of front end can be covered charged pin, avoid getting an electric shock.

2, when will be with plug insertion socket, only need the ring with annular insulating shield alignment socket Connected in star or annular sidewall just can make the pin alignment receptacles, therefore do not exist plugs and sockets to plug together Hard problem.

3, plug can be done 360 degree rotations on socket, and both can plug together with any relative direction, are convenient to the connection between the electrical device, and for example they can be applied to the kettle body and the connection of the power supply between the kettle seat of separated electric kettle.
