[0003] For example, the utility model patent with publication number "CN214100183U" and the name "A Power Cord Rotary Connector" discloses a power cord rotary connector, which includes: a seat body that provides a placement cavity for a vertical multi-ring rotary joint; the vertical multi-ring rotary joint includes a rotating member, a plurality of annular contact surfaces arranged at intervals, and a first group of power cords electrically connected to the annular contact surfaces; a second group of power cords, which are provided with an electrical contact segment; the electrical contact segment is pressed on the annular contact surface to make the second group of power cords conductive with the first group of power cords; the second group of power cords is connected to the seat body, and the seat body provides a mounting portion for the rotating member, and the vertical multi-ring rotary joint is rotated relative to the seat body by means of the rotating member. Although it achieves the purpose of maintaining conductivity while rotating 360 degrees, the contact effect between the electrical contact segment and the annular contact surface is not very good, and poor contact is prone to occur. Utility Model Content

[0004] In view of the above-mentioned shortcomings, the purpose of the utility model is to provide a 360-degree conductive connector with reasonable structural design and good electrical contact effect.

[0005] In order to achieve the above purpose, the technical solution provided by the utility model is:

[0006] A 360-degree conductive connector comprises a rotating shaft, a circular ring, a connecting spring and a circuit substrate. A plurality of the circular rings are sleeved on the rotating shaft at intervals. The circular ring is integrally formed with axial end pins extending along the axial direction of the rotating shaft. The axial end pins on each circular ring are insulated. A plurality of the connecting springs are arranged on the circuit substrate. The two ends of the connecting springs are symmetrically bent upward to form two arc-shaped clamping parts that are adapted to the outer shape of the circular ring.

[0007] As a preferred solution of the utility model, the ends of the axial end feet all extend out of the end surface of the rotating shaft to facilitate connection.

[0008] As a preferred solution of the utility model, the distance between the lower parts of the bending positions at both ends of the connecting spring piece gradually widens to form a placement portion, and the bottom surface of the placement portion is a plane, which provides a stable structural support for the connecting spring piece and enhances the stability of the connection.

[0009] As a preferred solution of the utility model, the middle part of the edge of the placement part is turned downward to form a welding foot part, which can be welded to the circuit substrate, greatly enhancing the firmness and reliability of the connection.

[0010] As a preferred solution of the utility model, the number of the welding feet is two sides, which are symmetrically located in the middle of the two side edges of the placement part, further enhancing the firmness and reliability of the connection.

[0011] As a preferred solution of the utility model, the upper ends of the two arc-shaped clamping parts are symmetrically bent to form a flared part, which facilitates the quick insertion of the circular ring into the arc-shaped clamping part, and the assembly is simple and convenient.

[0012] As a preferred solution of the utility model, the number of the circular rings and the connecting spring sheets are consistent, so that each circular ring can match with the connecting spring sheet on the circuit substrate.

[0013] The beneficial effects of the utility model are as follows: the utility model has a reasonable structure, and two arc-shaped clamping parts are provided on the connecting spring sheet, which have a good matching effect with the shape of the circular ring, can be tightly clamped on the circular ring, have a good electrical contact effect, and can still maintain normal and stable current transmission during a 360-degree rotation, effectively ensuring the stability of the electrical connection, with high reliability and long service life; and the overall structure is simple and easy to implement, which is conducive to wide promotion and application, and is particularly suitable for electrical appliances such as hair dryers, hair clippers, curling irons, and hair straighteners.

[0020] Example: See Figures 1 to 4 The present embodiment provides a 360-degree conductive connector, which includes a rotating shaft 1, a ring 2, a connecting spring 3 and a circuit substrate 4. The number of the ring 2 and the connecting spring 3 is consistent, so that each ring 2 can be matched with the connecting spring 3 on the circuit substrate 4.

[0021] In this embodiment, the number of the circular rings 2 and the number of the connecting spring pieces 3 are both three. In other embodiments, the number of the circular rings 2 and the number of the connecting spring pieces 3 may also be two, four or more.

[0022] The three circular rings 2 are sleeved on the rotating shaft 1 at intervals. The circular rings 2 are integrally formed with axial end feet 21 extending along the axial direction of the rotating shaft 1. Preferably, the ends of the axial end feet 21 extend out of the end face of the rotating shaft 1 to facilitate welding with the wires. During production, a round copper tube is used to laser cut out the circular rings 2 and the axial end feet 21, and then placed in a bending mold for bending and forming. The required number of circular rings 2 is selected and placed in an injection mold. The axial end feet 21 are placed at intervals to form an insulating setting structure to avoid short circuits, and then injection molding is performed to obtain the rotating shaft 1 after solidification.

[0023] The three connecting springs 3 are arranged on the circuit substrate 4 at intervals corresponding to the circular ring 2. Specifically, the distance between the lower parts of the two ends of the connecting spring 3 is gradually widened to form a placement portion 31. The bottom surface of the placement portion 31 is a plane, which provides a stable structural support for the connecting spring 3 and enhances the stability of the connection. The middle part of the edge of the placement portion 31 is turned down to form a welding foot 32. Preferably, the number of the welding foot 32 is two sides, which are symmetrically located at the middle position of the two side edges of the placement portion 31, further enhancing the firmness and reliability of the connection. A welding hole 41 adapted to the welding foot 32 is provided on the circuit substrate 4. The welding foot 32 extends into the welding hole 41 and is welded, which is firmly installed and has high reliability.

[0024] The two ends of the connecting spring 3 are symmetrically bent upward to form two arc-shaped clamping parts 33 that match the shape of the ring 2. For easy assembly, the upper ends of the two arc-shaped clamping parts 33 are symmetrically bent to form flared parts 34, which facilitates the quick insertion of the ring 2 into the arc-shaped clamping parts 33, making assembly simple and convenient.

[0025] When assembling, refer to Figure 5 The flared portion 34 can conveniently insert the convenient ring 2 into the arc-shaped clamping portion 33 for assembly, and the two arc-shaped clamping portions 33 match the shape of the ring 2 well, can be tightly clamped on the ring 2, have good electrical contact effect, and can still maintain normal and stable current transmission during the 360-degree rotation process, effectively ensuring the stability of the electrical connection, high reliability, and long service life.

Therefore, the utility model is not limited to the specific implementations disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model.
