[0037] In one embodiment of the present invention, Figures 1 to 6 As shown, a power cord is provided, including a wire 10 and a plug 20. Further, the wire 10 in this embodiment includes a live wire, a neutral wire and a ground wire;

[0038] The plug 20 includes:

[0039] The shell 21 has a support seat inside, and a turning groove 22 is provided on the back of the shell 21; the turning groove 22 runs through the front end face and the rear end face of the shell 21, and the width of the turning groove 22 is greater than or equal to the diameter of the wire 10, and the wire 10 can rotate in the turning groove 22.

[0040] The conductive rotating shaft 23 is rotatably arranged on the support seat at both ends, and part of the conductive rotating shaft 23 is arranged in the turning groove 22 and connected to the wire 10; further, the conductive rotating shaft 23 is located in the middle position of the turning groove 22, and the conductive rotating shaft 23 divides the turning groove 22 into an upper turning groove 22 and a lower turning groove 22.

[0041] The conductive terminal 24 is fixed in the housing 21 . A conductive portion extends from the upper end of the conductive terminal 24 . The conductive portion is slidably fitted with the conductive shaft 23 .

[0042] Specifically, the wire 10 is connected to the portion of the conductive shaft 23 exposed in the turning groove 22. When the wire 10 is located in the lower turning groove 22, when the position between the wire 10 and the plug 20 needs to be changed, the wire 10 is moved to rotate the conductive shaft 23, and the wire 10 moves toward the upper turning groove 22. Finally, the wire 10 located in the lower turning groove 22 is transferred to the upper turning groove 22. During the rotation, the conductive shaft 23 and the conductive portion of the conductive terminal 24 maintain a sliding fit to achieve electrical connection. There will be no power outage during the rotation, which can meet the usage requirements of different environments.

[0043] In another embodiment of the utility model, the conductive shaft 23 includes a metal part 231 and an insulating part 232 that are alternately connected; the electric wire 10 is electrically connected to the metal parts 231. Specifically, since the electric wire 10 has a live wire, a neutral wire and a ground wire, the conductive terminal 24 is correspondingly provided with a live wire terminal, a neutral wire terminal and a ground wire terminal; the provided metal parts 231 are respectively connected to the live wire and the live wire terminal, the neutral wire and the neutral wire terminal, and the ground wire and the ground wire terminal; an insulating part 232 is also provided between each metal part 231 to avoid the connection between each metal part 231, meet the connection requirements, and avoid the short circuit.

[0044] In another embodiment of the present invention, Figure 2 and Figure 5 As shown, the conductive shaft 23 is provided with a fixing groove 233, and the fixing groove 233 extends into each of the metal parts 231. Specifically, the wire 10 is fixed in the fixing groove 233 to achieve electrical connection with the corresponding metal part 231, and the wire 10 will not leak out of the surface of the conductive shaft 23, thereby avoiding interference when the conductive shaft 23 rotates.

[0045] In another embodiment of the present invention, Figure 5 As shown, the fixing groove 233 includes a first groove portion 2331 and a second groove portion 2332 which are connected. The first groove portion 2331 is arranged along the axial direction of the conductive shaft 23, and the second groove portion 2332 is arranged along the axial direction of the conductive shaft 23. The second groove portion 2332 is located in the middle of the first groove portion 2331. Specifically, the first groove portion 2331 is arranged along the axial direction of the conductive shaft 23, so that part of the wire 10 is connected to the metal portion 231 along the first groove portion 2331, and the second groove portion 2332 is arranged along the circumference of the conductive shaft 23, that is, the second groove portion 2332 is vertically distributed with the first groove portion 2331, and part of the wire 10 is connected to the corresponding metal portion 231 along the second groove portion 2332. In this way, when part of the wire 10 is fixed to the second groove portion 2332, it will affect the fixing of other parts of the wire 10 to the first groove portion 2331, thereby reducing the difficulty of processing.

Specifically, since the diameter of the support portion 234 is smaller than the metal portion 231 and the insulating portion 232, when the support portion 234 is fixed to the support seat, the support seat and the side of the metal portion 231 are in contact or nearly in contact, thereby playing a role of limiting. The structure is simple and can meet the limit of the conductive shaft 23, and the conductive shaft 23 is prevented from being offset.

[0047] In another embodiment of the present invention, Figure 2 and Figure 6 As shown, the conductive terminal 24 includes a first conductive portion 241 and an elastic second conductive portion 242, wherein the first conductive portion 241 is fixed in the housing 21, the first conductive portion 241 extends out of the housing 21, and the second conductive portion 242 is connected between the first conductive portion 241 and the conductive shaft 23. Specifically, the elastic second conductive portion 242 ensures that it is in close contact with the conductive shaft 23, so as to avoid a gap between the conductive shaft 23 and the second conductive portion 242 when the conductive shaft 23 rotates, thereby preventing a circuit from being broken.

[0048] In another embodiment of the utility model, the upper surface of the second conductive part 242 has a protrusion, and the protrusion is in close contact with the conductive shaft 23. Specifically, the upper surface of the second conductive part 242 is provided with a protrusion, and the protrusion is in close contact with the conductive shaft 23, and the second conductive part 242 is deformed to generate elastic force, and the elastic force keeps the protrusion in close contact with the conductive shaft 23.

[0049] Furthermore, the protrusion is formed by folding the free end of the second conductive portion 242 upward.

[0050] Furthermore, the protrusion is formed by the second conductive portion 242 through a stamping process.

[0051] In another embodiment of the utility model, the second conductive part 242 has an angle with the horizontal plane, so that the second conductive part 242 keeps in contact with the conductive shaft 23. Specifically, the free end of the second conductive part 242 is tilted upward, and further, the second conductive part 242 is tilted away from the free end of the first conductive part 241, so that when the conductive shaft 23 contacts the second conductive part 242, the second conductive part 242 generates an elastic force, and the elastic force keeps the second conductive part 242 and the conductive shaft 23 in contact.

[0052] In another embodiment of the utility model, an elastic member is provided between the second conductive part 242 and the housing 21. Specifically, an elastic member is provided between the second conductive part 242 and the housing 21, and under the action of the elastic member, the stability of the second conductive part 242 and the conductive shaft 23 is improved. Furthermore, the elastic member is silicone, a spring, etc.

[0053] In another embodiment of the present invention, Figure 2 As shown, the housing 21 includes an upper shell 211 and a lower shell 212, the upper shell 211 is provided with an upper support seat 213, the lower shell 212 is provided with a lower support seat 214, the upper support seat 213 and the lower support seat 214 are both provided with arc grooves, the two arc grooves constitute positioning holes, and the two ends of the conductive shaft 23 are connected to the positioning holes. Specifically, during installation, the wire 10 is connected to the conductive shaft 23 after passing through the turning groove 22, and then the support portion 234 of the conductive shaft 23 is installed on the upper support seat 213. When the upper shell 211 and the lower shell 212 are connected, the lower support seat 214 and the upper support seat 213 limit the support portion 234 in the positioning hole, reducing the difficulty of assembly.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
