Abstract

The utility model relates to an electric connector, which comprises a socket and a plug which are capable of plugging in and rotating relative to each other, wherein the socket is provided with a central wire connection terminal and a circular wire connection terminal of the same center with the central wire connection terminal, the plug is provided with an elastic contact plate of the same center with the central wire connection terminal and the circular wire connection terminal. When the plug is plugged in the socket, the elastic contact plate contacts with corresponding taper direct face, which guarantees good contact between the plug elastic electric contact plate and the circular surface and not easy to cut off. At the same time, the earthling central terminal is slightly higher than the circular surface, which guarantees that earthling is firstly realized when the appliance is in use and is very reliable.

Description

The electricity connector

Technical field

The utility model relates to a kind of electric connector, particularly a kind of electric connector that is applicable to wireless electric heating vessel.

Background technology

The existing electrical connector that is used for cordless electric appliance, general all by a plug with its mutually the socket of fit form, plug usually and consuming device make one, socket is connected with power line, when making electrical appliance, power line on the socket connects power supply and as pedestal, the plug of making one with consuming device places on the socket, the work of promptly switching on, so just can be so that consuming device is broken away from the puzzlement of power line, very convenient, and it is safe and reliable, the patent No. is that the Chinese utility model patent " electrical cnnector " of CN00233024.5 discloses so a kind of electrical cnnector by socket and the mutual fit of plug, the binding post that annular is arranged in the socket, the elasticity electric contact point that combines with annular binding post in the described socket is arranged on the plug, the binding post of annular is by the inwall of conduction in the described socket, outer wall and intermediate insulation material layer are formed, each elasticity electric contact point on the plug has dead ring isolated, when plug combines with socket, each annulus wall in each elasticity electric contact point on the plug and the socket combines, avoid the generation of electric arc, each is organized all has dead ring isolated between the contact, and the contact of zero potential is between the phase line, connector insulation shielding performance is further improved, guaranteed the safe and reliable of use.But each elasticity electric contact point is that a face contacts with the interior annulus wall of socket in the plug, after long-term use, because the regular plug of plug and socket, make wearing and tearing of elasticity electric contact point and distortion easily, thereby cause the loose contact of elasticity electric contact point and annulus wall, thereby make consuming device to obtain power supply by this electric connector reliably, require further improvement its structure thus, with the reliability that guarantees that such long term device is used.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of plug elasticity electric contact point and socket annulus wall is difficult for disconnecting safe and reliable electric connector.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this electricity connector, it includes can peg graft and can counterrotating plug and socket mutually, be provided with a center binding post in the socket, and have with the concentric annulus wall of this center binding post as the annular binding post, and be provided with in the plug and center binding post and the corresponding elasticity electric contact point of annular binding post, and there is dead ring to isolate each elasticity electric contact point, it is characterized in that: the terminal tapered spigot surface of described annulus wall, when plug insertion socket, described elasticity electric contact point and the tapered guide surface corresponding with it contact.

For guaranteeing closely cooperating and rotation flexibly of plug and socket, the dead ring internal diameter of described plug matches with the external diameter of described socket annulus wall.

Be to guarantee Central Post ground connection, described center binding post is a shape inserting column, and when plug insertion socket, described center binding post inserts first dead ring ground connection that contacts with the elasticity electric contact point.

Further when guaranteeing that electrical equipment uses, ground connection and last disconnection the at first, described center binding post can be higher than the annulus wall.

Compared with prior art, advantage of the present utility model is the setting by the terminal tapered guide surface of socket annulus wall, guaranteed that plug elasticity electric contact point contacts with the good of this annulus wall, make it be difficult for disconnecting dead electricity, simultaneously, the design of the ground connection center terminal of a little higher than annulus wall is when having guaranteed that electrical equipment uses, ground connection is realized and last the disconnection at first, and is fool proof reliable.

Embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Shown in Fig. 1～3, be used for the electric connector of wireless electric heating vessel for the utility model embodiment is a kind of, it comprises can peg graft and can counterrotating socket 1 and plug 2 mutually;

Socket 1 central part is provided with a center binding post 11, and have with the

concentric annulus wall

12 and 13 of this center binding post 11 as the annular binding post, the terminal

tapered spigot surface

121 and 131 of annulus wall, as shown in Figure 2;

And be provided with in the plug 2 and center binding post 11 and

annular binding post

12,13 corresponding elasticity

electric contact points

21,22 and 23, and have

dead ring

24,25 and 26 to isolate each elasticity electric contact point, as shown in Figure 3;

When plug 2 inserts socket 1, the dead ring 24 in the middle of center binding post 11 inserts and the ground connection that contacts with elasticity electric contact point 21, two elasticity

electric contact points

22 and 23 line and zero line of starting to exchange fire that contact with the

tapered guide surface

121 and 131 of its

annular binding post

12 and 13 ends respectively in addition, because the setting of

annulus wall

12 and 13 terminal

tapered guide surface

121 and 131, when plug 2 inserts socket 1, elasticity

electric contact point

22 and 23 is under action of gravity, tightly be attached on the annulus wall, guaranteed that plug elasticity electric contact point contacts with the good of this annulus wall, made it be difficult for disconnecting dead electricity;

During design, the center binding post 11 a little higher than

annulus walls

12 and 13 of axle shape inserting column, when plug 2 inserts socket 1, the center binding post 11 first ground connection that contact with the elasticity electric contact point 21 of plug 1, play shielding action, and then be that

annular binding post

12 and 13 contacts with elasticity

electric contact point

22 and 23, energized, otherwise, when plug 2 inserts socket 1, then be to break away from phase line earlier then to disconnect earth connection, when having guaranteed that like this electrical equipment uses, ground connection is realized and last the disconnection at first, very safe and reliable.
