The power connector that uses in existing separated electric water pot, because structural defective, there is following problem: at first, conducting simultaneously was electrically connected for three groups when last socket in the past was connected with following socket, be ground wire, live wire, zero line connects, can give the designer inconvenient greatly in use, especially when needs use direct current to connect; Its two, in the past connector adopts the plane to cooperate; Easily produce eccentric phenomena when last socket is connected with following socket and cause and produce electric loose contact sometimes, and cause conductive contact to burn to death and influence useful life of connector; The 3rd, connector lower terminal upper surface of support in the past adopts planar design, can ponding when down socket flows down as water at socket lower terminal bearing down, and connector has at least one group of electrified body to expose, thus a series of potential safety hazard can appear in use.

Summary of the invention:

The purpose of this utility model is the defective that overcomes prior art, provides a kind of simple in structure, safe and reliable, non-damageable power connector.

The purpose of this utility model is achieved in that

A kind of power connector, it comprises socket and following socket, be provided with upper connecting terminal in the socket shell on described in the socket, also be provided with power spring in the cavity of socket shell on described, described socket down comprises lower terminal bearing and following plug casing; On the lower terminal bearing of described down socket, be provided with lower connecting terminal and following contact stud, it is characterized in that the socket shell also is provided with an interchange zero line copper ring on described to exchange the live wire copper ring with one; Under also being provided with fire line terminal under the interchange on the described lower terminal bearing, exchanging zero terminal with exchanges under ground wire terminal, and also be with back-moving spring on the contact stud down described, be provided with one at the top of described back-moving spring and exchange ground wire and cover.

The direct current zero line copper ring on the described plug casing down and the contact-making surface of last socket are for having arc-shaped curved surface.

Described lower terminal upper surface of support is descending conical surface, and is provided with osculum at the edge of described conical surface.

Live contact on described in socket and the play socket be located at respectively described on the inwall of socket shell and following plug casing.

The utility model adopts upward, and socket combines, is provided with osculum and live contact internal hidden type structure with the curved surface of following socket, and increase binding post, make the utility model on last socket and horizontal plane that following socket matches, to do the rotation arbitrarily of 360 degree, and guarantee to be electrically connected good, easy to use, and safe and reliable.

Embodiment:

Be embodiment of the present utility model with accompanying

drawing

1,2,3,4,5,6,7,8,9,10 below, the utility model be further detailed:

In the present embodiment, the utility model is made up of last socket and following socket, socket shell 8 on socket comprises on described, be located at described on power spring 4 in the cavity of socket shell 8, the zero line copper ring 10 that exchanges that be connected ground wire terminal 3 in the interchange on the power spring 4, is pressed in the cavity of the interchange ground wire contact head 7 of the other end that exchanges the interchange ground wire terminal gland 2 of going up ground wire terminal 3, is pressed in power spring 4 and the contact jaw that is located at socket shell 8 exchanges live wire copper ring 9 with one; On described, also be provided with direct current zero terminal and direct current fire line terminal in the socket shell 8.Install socket for convenience, the top of socket is provided with a mounting bracket 1 on described.

Described socket down comprises lower terminal bearing 17 and following plug casing 13; Described plug casing 13 tops down are connected with direct current zero line copper ring 11 and direct current live wire copper ring 12, by plug casing 13, direct current zero line copper ring 11 and direct current live wire copper ring 12 constitute a cavity down, direct current zero line copper ring 11 is positioned at topmost, and the contact-making surface of direct current zero line copper ring 11 and last socket is for having arc-shaped curved surface.Ground wire terminal 19 and following contact stud 16 under being provided with zero terminal 20 under fire line terminal 18 under the interchange, the interchange on the described lower terminal bearing 17, exchanging, following contact stud 16 is located at the centre position of lower terminal bearing 17, and also be with back-moving spring 15 on the contact stud 16 down described, be provided with one at the top of described back-moving spring 15 and exchange ground wire lid 14.In order to make that socket has drain function down, described lower terminal bearing 17 upper surfaces are designed to descending conical surface 23, and be provided with osculum 22 at the edge of described conical surface, like this, when water flows down above following socket, just can prolong conical surface 23 smoothly and flow to osculum 22 discharges, guarantee safe handling of the present utility model.Live contact 21 in the following socket is located at down on the inwall of plug casing 13, can avoids electrified body to expose, bring psychological fear to the user thereby may occur potential safety hazard in use.
