[0037] In order to enable the above-mentioned objects, features and advantages of the present application to be more clearly understood, the present application will be further described below with reference to the drawings and specific embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0038] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0039] The power cord connection structure of some embodiments of the present invention is described below with reference to the accompanying drawings.

[0040] like Figures 1 to 7 As shown, this embodiment discloses a power cord connection structure, including: a first connector 1, which is used for fitting and installing with a host; a second connector 2, which is rotatably connected to the first connector 1, and the second connector 2 and the first connector 1 enclose a mounting cavity 101, and the second connector 2 is connected to a power cord 3; and a conductive component 4, which includes a first conductive element 41 and a second conductive element 42, which are located in the mounting cavity 101, and one of the first conductive element 41 and the second conductive element 42 is disposed in the first connector 101. The first conductive element 41 and the second conductive element 42 are disposed on the second connector 2 and are electrically connected to the power line 3. The first conductive element 41 has a conductive ring 411 formed on the side facing the second conductive element 42, which is coaxially disposed with the second connector 2. The second conductive element 42 has a contact 4223 formed on the side facing the first conductive element 41. The contact 4223 is configured to slide relative to the conductive ring 411 along the circumference of the conductive ring 411 and make contact with the conductive ring 411 to conduct electricity when the second connector 2 rotates relative to the first connector 1.

[0041] This application provides a power cord connection structure, including a first connector 1, a second connector 2, and a conductive component 4. The second connector 2 is connected to a power cord 3 and is rotatable relative to the first connector 1. The first connector 1 and the second connector 2 are respectively provided with a first conductive element 41 and a second conductive element 42. The first conductive element 41 forms a conductive ring 411 coaxially arranged with the second connector 2. Thus, when the second connector 2 rotates relative to the first connector 1, the second conductive element 42 and the first conductive element 41 rotate relative to each other simultaneously. The contact 4223 of the second conductive element 42 will slide and abut against the conductive ring 411 along its circumference, and the second conductive element 42 and the first conductive element 41 remain connected. Therefore, by adopting the power cord connection structure of this application, when the user rotates the main unit of the product during product use, the main unit and the first connector 1 can rotate relative to the second connector 2. Thus, on the one hand, the cooperation of the first conductive element 41 and the second conductive element 42 can ensure stable current conduction, and on the other hand, the power cord 3 will not be driven to rotate and twist, thereby effectively preventing damage caused by the twisting of the power cord 3 and helping to extend the service life of the product.

[0042] like Figure 2As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further defined as: the first connecting head 1 is provided with a mounting groove 102 on the side facing the second connecting head 2, the second connecting head 2 is inserted into the mounting groove 102 at the end away from the power cord 3 and cooperates with the inner wall of the mounting groove 102 to form a mounting cavity 101, the inner peripheral wall of the mounting groove 102 is recessed to form a first annular groove 103, and the outer peripheral wall of the second connecting head 2 is formed with an annular protrusion 211, which is adapted to be mounted in the first annular groove 103 so that the second connecting head 2 is rotatably connected to the first connecting head 1. By respectively providing the annular protrusion 211 on the second connecting head 2 and the first annular groove 103 on the first connecting head 1, and using the cooperation of the annular protrusion 211 and the first annular groove 103, the first annular groove 103 can provide support for the annular protrusion 211, so that the second connecting head 2 can rotate relative to the first connecting head 1 and will not fall off.

[0043] As shown in the drawings, Figure 2 and Figure 7 As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further defined as: the first connecting head 1 includes a connecting cover 11 and a mounting seat 12, the first conductive part 41 or the second conductive part 42 is arranged on the connecting cover 11, the connecting cover 11 is detachably arranged on the mounting seat 12, the connecting cover 11 cooperates with the mounting seat 12 to form the mounting groove 102 and the first annular groove 103, and the opposite sides of the annular protrusion 211 abut against the connecting cover 11 and the mounting seat 12, respectively. By arranging the separable connecting cover 11 and the mounting seat 12 to form the mounting groove 102 and the first annular groove 103, the second connecting head 2 can be greatly facilitated to be mounted on the first connecting seat, and the connecting cover 11 and the mounting seat 12 can clamp the annular protrusion 211 to form a supporting and limiting action, so that the second connecting head 2 can rotate relative to the first connecting head 1 and will not fall off.

[0044] As shown in the drawings, Figure 2 and Figure 7 As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further defined as: the mounting seat 12 includes a seat body 121 and a limiting ring 122, the seat body 121 is annular, and the limiting ring 122 is coaxially arranged on the top of the seat body 121, the limiting ring 122 cooperates with the seat body 121 to form a limiting groove 104, and the connecting cover 11 is adapted to be inserted into the limiting groove 104. By using the above structure, the seat body 121 and the limiting ring 122 cooperate to form the limiting groove 104 to facilitate the positioning and installation of the connecting cover 11, so that after the first conductive part 41 or the second conductive part 42 is arranged on the connecting cover 11, the alignment and connection of the conductive ring 411 and the contact 4223 can be better achieved.

[0045] As shown in the drawings, Figure 7As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer peripheral wall of the mounting base 12 is formed with an abutment platform 123, and the abutment platform 123 is provided with a connection hole 105 for connecting with the host. By adopting the above structure, the connection hole 105 can cooperate with the fastener to ensure that the first connector 1 can be securely installed with the host, thereby ensuring that the conductive component 4 can be stably connected to the circuit board assembly in the host and is not easily loosened.

[0046] like Figure 2 , Figure 5 and Figure 6 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the second connector 2 includes a rotating base 21 and a connector body 22, the connector body 22 is connected to a power cord 3, the conductive component 4 also includes a third conductive element 43, the third conductive element 43 is fixedly disposed on the connector body 22 and electrically connected to the power cord 3, the rotating base 21 is rotatably connected to the first connector 1, the first conductive element 41 or the second conductive element 42 is fixedly disposed on the rotating base 21, the connector body 22 can be detached from the rotating base 21, when the connector body 22 is connected to the rotating base 21, the connector body 22, the third conductive element 43 and the power cord 3 can rotate relative to the first connector 1 under the drive of the rotating base 21, and the third conductive element 43 contacts and conducts electricity with the first conductive element 41 or the second conductive element 42. By adopting the above structure, one end of the connector body 22 is connected to the power cord 3, and the other end can be detachably connected to the rotating base 21. When the connector body 22 is connected to the rotating base 21, the third conductive element 43 provided on the connector body 22 can contact the first conductive element 41 or the second conductive element 42 provided on the rotating base 21 to achieve electrical connection. Under the limiting cooperation between the rotating base 21 and / or the first conductive element 41 or the second conductive element 42 and the connector body 22 and / or the third conductive element 43, the power cord 3 can rotate with the rotating base 21 relative to the first connecting base. Thus, when the first connecting base rotates with the host, the power cord 3 can be prevented from twisting and being damaged. When the device is no longer in use, the user can remove the connector body 22 and the power cord 3 from the rotating base 21, which makes the storage of the power cord 3 more convenient. Furthermore, when a part of the power cord connection structure is damaged, that part can be replaced instead of replacing the entire power cord connection structure, thereby saving maintenance costs.

[0047] like Figure 2 and Figure 5 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the outer peripheral wall of the rotating seat 21 is formed with an annular protrusion 211, and the annular protrusion 211 is adapted to be installed with the first annular groove 103 so that the rotating seat 21 is rotatably connected to the first connector 1.

By adopting the above structure, the insertion of the conductive post 421 into the first slot 401 enables the conductive post 421 and the third conductive member 43 to be tightly connected, which can effectively prevent the occurrence of poor contact, and the frictional resistance formed between the two can make the joint body 22 and the power cord 3 more stably connected with the rotating seat 21 and rotate with the rotating seat 21 relative to the first connecting seat.

[0049] As shown in the drawings, Figure 2 and Figure 6 As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further defined as: the joint body 22 is provided with a second slot 201 at one end facing the rotating seat 21, the third conductive member 43 is arranged at the bottom of the second slot 201, and the first conductive member 41 or the second conductive member 42 is adapted to be inserted into the second slot 201 at one end away from the mounting cavity 101 and connected with the third conductive member 43. By adopting the above structure, the insertion of the first conductive member 41 or the second conductive member 42 into the second slot 201 can expand the connection area between the two, so that the increased frictional resistance can make the joint body 22 and the power cord 3 more stably connected with the rotating seat 21 and rotate with the rotating seat 21 relative to the first connecting seat.

[0050] As shown in the drawings, Figures 1 to 3 As shown in the drawings, in addition to the features of the above embodiments, the present embodiment is further defined as: the first connecting head 1 is provided with a mounting groove 102 at one side facing the second connecting head 2, the rotating seat 21 is arranged in the mounting groove 102 and cooperates with the inner wall of the mounting groove 102 to form the mounting cavity 101, the peripheral wall of the mounting groove 102 is formed with notches 106 at opposite sides, the peripheral wall of the joint body 22 is recessed to form a second annular groove 202, the notches 106 are arranged opposite to the second annular groove 202, and the limiting member 5 is annular, the limiting member 5 is sleeved on the outside of the first connecting head 1, and the limiting member 5 partially penetrates through the notches 106 and extends into the second annular groove 202 to limit the up-and-down movement of the joint body 22 relative to the first connecting head 1. By adopting the above structure, when the joint body 22 is connected with the rotating seat 21, the limiting member 5 partially penetrates through the notches 106 and extends into the second annular groove 202, so that the limiting member 5 cooperates with the second annular groove 202 to form a limiting action, which supports the joint body 22 without affecting the rotation of the joint body 22 with the rotating seat 21, and limits the up-and-down movement and falling of the joint body 22 relative to the first connecting head 1, and in addition, the limiting member 5 is located on the outside of the first connecting head 1, which can facilitate the installation personnel to assemble.

The limiting member 5 is a spring with elasticity. When the limiting rib 52 of the limiting member 5 is located in the second annular groove 202, it can effectively limit the connector body 22, thereby preventing the power cord 3 from being pulled during use, causing it, the connector body 22, and the third conductive part 43 to fall off and suddenly cut off the power. After the device is finished using, the user only needs to press the pressing part 53 to bring it close to the positioning part 51, which will cause the limiting member 5 to deform.
