Therefore, they cannot be understood as a limitation on the present invention.

[0028] Embodiment 1:

[0029] like Figure 1 to Figure 5 As shown, a swivel connector includes a conductive column 1, a conductive sleeve 1 2, a conductive sleeve 2 3, and a conductive sleeve 3 4. The conductive column 1, the conductive sleeve 1 2, the conductive sleeve 2 3, and the conductive sleeve 3 4 are all made of conductive materials. For example, the conductive column 1, the conductive sleeve 1 2, the conductive sleeve 2 3, and the conductive sleeve 3 4 are made of copper.

[0030] refer to Figure 2 , Figure 3 , Figure 4 As shown, the conductive column 1 is in the shape of a long cylindrical strip as a whole, and the conductive sleeve three 4, the conductive sleeve two 3, and the conductive sleeve one 2 are distributed in sequence along the length direction of the conductive column 1 and are arranged on the outer periphery of the conductive column 1 at intervals.

[0031] The conductive sleeve 1 2, conductive sleeve 2 3, and conductive sleeve 3 4 are copper rings with different diameters as a whole. The outer diameters of the conductive sleeve 3 4, conductive sleeve 2 3, and conductive sleeve 1 2 are arranged to increase in sequence. The conductive sleeve 1 2, conductive sleeve 2 3, conductive sleeve 3 4, and conductive column 1 cooperate with each other to form a conical distribution extending to one side, and the central axes of the conductive column 1, conductive sleeve 1 2, conductive sleeve 2 3, and conductive sleeve 3 4 coincide with each other, so that the conductive column 1, conductive sleeve 1 2, conductive sleeve 2 3, and conductive sleeve 3 4 can realize overall rotation.

[0032] Furthermore, an insulating injection molding body 5 is filled between the conductive column 1, the conductive sleeve three 4, the conductive sleeve two 3, and the conductive sleeve one 2, and then the conductive column 1, the conductive sleeve three 4, the conductive sleeve two 3, and the conductive sleeve one 2 are integrally injection molded through the injection molding body 5, and the insulation between the conductive column 1, the conductive sleeve one 2, the conductive sleeve two 3, and the conductive sleeve three 4 is ensured, so as to avoid safety problems such as conductive short circuit between the conductive column 1, the conductive sleeve one 2, the conductive sleeve two 3, and the conductive sleeve three 4 during use of this embodiment.

[0033] The conductive sleeve three 4, the conductive sleeve two 3, and the conductive sleeve one 2 are arranged on the periphery of the injection molding body 5. Specifically, the periphery of the injection molding body 5 is provided with a convex ring one 52, a convex ring two 53, and a convex ring three 54 in a stepped distribution. The outer diameter of the convex ring three 54 is matched with the inner diameter of the conductive sleeve three 4, and the conductive sleeve three 4 is installed on the convex ring three 54. The outer diameter of the convex ring two 53 is matched with the inner diameter of the conductive sleeve two 3. The conductive sleeve two 3 is installed on the convex ring two 53. The outer diameter of the convex ring one 52 is matched with the inner diameter of the conductive sleeve one 2, and the conductive sleeve one 2 is installed on the convex ring one 52.

[0034] Furthermore, the plug-in end 13 of the conductive column 1 is arranged through the injection molded body 5, and the conductive sleeve three 4, the conductive sleeve two 3, and the conductive sleeve one 2 are distributed close to the plug-in end 13 in sequence, that is, the conductive sleeve three 4 is closest to the plug-in end 13, the conductive sleeve one 2 is farthest from the plug-in end 13, and the conductive sleeve two 3 is located between the conductive sleeve three 4 and the conductive sleeve one 2.

[0035] The plug-in terminal 13, the conductive sleeve three 4, the conductive sleeve two 3, and the conductive sleeve one 2 form a connector for providing power to the electrical appliance, that is, the plug-in terminal 13, the conductive sleeve three 4, the conductive sleeve two 3, and the conductive sleeve one 2 are injection-molded into an integrated structure through the injection molding body 5, and plugged into the electrical appliance to provide power for the operation of the electrical appliance, thereby providing a rotatable plug-in power connection for the electrical appliance, so that the electrical appliance can be rotated when in use, and it is not easy to cause the power cord to be twisted or broken, thereby improving the safety and reliability of the use of the electrical appliance.

[0036] Specifically, refer to Figure 1 , Figure 3 As shown, the other end of the conductive column 1 is provided with a connecting end 11 penetrating the injection molded body 5, and the outer periphery of the connecting end 11 is provided with a wire pressing terminal 3 42 connected to the conductive sleeve 3 4 , a wire pressing terminal 2 32 connected to the conductive sleeve 2 3 , and a wire pressing terminal 1 22 connected to the conductive sleeve 1 2 .

[0037] The crimping terminal 1 22, the crimping terminal 2 32, and the crimping terminal 3 42 are in the shape of a hollow cylinder. The external connecting wires can be cold-pressed and connected to the connecting terminal 11, the crimping terminal 1 22, the crimping terminal 2 32, and the crimping terminal 3 42 respectively, and then the plug-in terminal 13, the conductive sleeve 1 2, the conductive sleeve 2 3, and the conductive sleeve 3 4 provide different types of power supplies (or signal lines) for the electrical equipment according to the properties of the corresponding connecting wires.

[0038] For example, when the live wire is connected to the connection terminal 11, the plug-in terminal 13 becomes the "live wire" terminal, when the neutral wire is connected to the pressure terminal three 42, the conductive sleeve three 4 becomes the "neutral wire" terminal, when the signal wire is connected to the pressure terminal one 22, the conductive sleeve one 2 becomes the "signal transmission" terminal, and then the design positions of the conductive transmission contacts and the signal transmission contacts of this embodiment can be adjusted according to actual needs, that is, the conductive column 1, the conductive sleeve one 2, the conductive sleeve two 3, and the conductive sleeve three 4 can be arbitrarily set as conductive transmission contacts or signal transmission contacts according to actual needs. It can also be understood that the conductive column 1, the conductive sleeve one 2, the conductive sleeve two 3, and the conductive sleeve three 4 can be arbitrarily adjusted to conductive transmission contacts or signal transmission contacts according to different external connecting lines, thereby improving the practicality of the product.

[0039] This embodiment can be adjusted to different types of power connection plugs to be plugged into electrical appliances to provide power and other needs for the electrical appliances.

By means of the extension section 1 21, the extension section 2 31 and the clamping ring 12 injection-molded in the injection molded body 5, the conductive column 1, the conductive sleeve 2 3 and the conductive sleeve 3 4 can be more firmly installed on the injection molded body 5 to increase the firmness and reliability of the installation of this embodiment.

[0041] The injection molded body 5 is provided with a protrusion 51 extending to both sides on one side close to the connection end 11 . The protrusion 51 can facilitate the external installation and fixation of the present embodiment, thereby improving the reliability of use.

[0042] Before the injection molding body 5 is fixed by injection molding, the conductive column 1, conductive sleeve three 4, conductive sleeve two 3, and conductive sleeve one 2 can be rotated and adjusted according to actual needs. The relative positions of the conductive sleeve one 2, the conductive sleeve two 3, and the conductive sleeve three 4 can be adjusted to adjust the angle between the connecting end 11, the wire pressing end two 32, and the wire pressing end three 42.

[0043] refer to Figure 1As shown, the second wire pressing end 32, the connecting end 11, and the third wire pressing end 42 are distributed at 180 degrees, and the distribution angle formed between the second wire pressing end 32, the connecting end 11, and the third wire pressing end 42 can also be adjusted according to actual needs.

[0044] Embodiment 2:

[0045] like Figure 6-7 As shown, the difference between this embodiment and embodiment 1 lies in the arrangement of the wire pressing terminal 1 22, the wire pressing terminal 2 32, and the wire pressing terminal 3 42. An opening is provided on one side of the wire pressing terminal 1 22, the wire pressing terminal 2 32, and the wire pressing terminal 3 42 to facilitate cold pressing and fixing of external connecting wires.

[0046] And reference Figure 7 As shown, in this embodiment, the angle formed between the second crimping terminal 32, the connecting terminal 11, and the third crimping terminal 42 is 120 degrees, but it is not limited to being set to 120 degrees, and the above angle can be adjusted according to actual needs.

[0047] 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, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
