[0036] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Now, in conjunction with the accompanying drawings, the preferred embodiments of the present invention will be described in detail.

[0037] An embodiment of the present invention provides a telescopic winding data cable module, as Figures 1 to 8 shown. The telescopic winding data cable module includes a housing 1, a rotating base 2, a data cable 3, a first circuit board 4, and a second circuit board 5; the rotating base 2 is rotatably installed in the housing 1, the first circuit board 4 is installed on the rotating base 2, the data cable 3 is wound on the rotating base 2 and is electrically connected to the first circuit board 4; the second circuit board 5 is installed in the housing 1 and is disposed opposite to the first circuit board 4.

[0038] One of the first circuit board 4 and the second circuit board 5 is provided with a circular conductive circuit 41, and the other is provided with an electrical connector 51; the electrical connector 51 has a first electrical connection arm 511 and a second electrical connection arm 512, and the first electrical connection arm 511 and the second electrical connection arm 512 of the same electrical connector 51 abut against the same circular conductive circuit 41 to electrically connect the first circuit board 4 and the second circuit board 5.

[0039] In the telescopic winding data cable module of the present invention, one of the first circuit board 4 and the second circuit board 5 is provided with a circular conductive circuit 41, and the other is provided with an electrical connector 51. The electrical connector 51 has a first electrical connection arm 511 and a second electrical connection arm 512, and the first electrical connection arm 511 and the second electrical connection arm 512 of the same electrical connector 51 abut against the same circular conductive circuit 41 to electrically connect the first circuit board 4 and the second circuit board 5. In this way, an electrical connector 51 provides two electrical connection contact points with the same circular conductive circuit 41 through the first electrical connection arm 511 and the second electrical connection arm 512, improving the electrical connection stability between the first circuit board 4 and the second circuit board 5, and having a stronger load-bearing capacity for high-power use, and being more suitable for high-power use scenarios.

[0040] Specifically, when the data cable 3 is stretched or wound onto the rotating base 2, since the stretching or winding of the data cable 3 drives the rotating base 2 to rotate, the first circuit board 4 installed on the rotating base 2 is driven to rotate, while the second circuit board 5 remains stationary. During the rotation of the first circuit board 4, the first electrical connection arm 511 and the second electrical connection arm 512 will always abut against the circular conductive circuit 41, thereby maintaining the electrical connection between the first circuit board 4 and the second circuit board 5, and the first electrical connection arm 511 and the second electrical connection arm 512 slide relative to the circular conductive circuit 41 on the circular conductive circuit 41.

[0041] Regarding the specific arrangement of the annular conductive line and the electrical connector 51, in one embodiment, the annular conductive line 41 is arranged on the first circuit board 4, and the electrical connector 51 is arranged on the second circuit board 5. In another embodiment, the annular conductive line 41 is arranged on the second circuit board 5, and the electrical connector 51 is arranged on the first circuit board 4. Preferably, as Figure 6 and Figure 7 As shown, the annular conductive circuit 41 of the telescopic winding data line module of the present invention is arranged on the first circuit board 4, and the electrical connector 51 is arranged on the second circuit board 5. For the installation of the data line 3, a winding disk 22 is arranged on the rotating base 2, and the data line 3 is wound on the winding disk 22.

[0042] Alternatively, if Figure 8 and Figure 9 As shown, the electrical connector 51 further includes a mounting section 5111, and the first electrical connecting arm 511 and the second electrical connecting arm 512 further include a connecting section 5112 and an abutting section 5113. The mounting section 5111 is mounted on the first circuit board 4 or the second circuit board 5, and the connecting sections 5112 of the first electrical connecting arm 511 and the second electrical connecting arm 512 are respectively connected to the two ends of the mounting section 5111, and the abutting section 5113 is connected to the connecting section 5112. Two contact points with the annular conductive circuit 41 are provided by the abutting sections 5113 of the first electrical connecting arm 511 and the second electrical connecting arm 512. The design of the connecting section 5112 enables the abutting section 5113 to be in more stable contact with the annular conductive circuit 41, and enables the electrical connector 51 to be stably installed.

[0043] Optionally, the connecting section 5112 is tilted at one end away from the mounting section 5111, and the abutting section 5113 is U-shaped, with the opening of the abutting section 5113 facing away from the annular conductive line 41. The connecting section 5112 is tilted at one end away from the mounting section 5111, and the electrical connector 51 is in the shape of an "arch bridge" as a whole, so that the connecting section 5112 has a certain elasticity in structure, and can provide a certain buffer and elastic support when the abutting section 5113 contacts the annular conductive line 41. The U-shaped structure of the abutting section 5113 can better abut against the annular conductive line 41 to form a stable contact point. In another embodiment, Figure 12 As shown, the mounting section 5111 and the connecting section 5112 are connected via an extended support portion 5114 , and the extended support portion 5114 is extended toward the first circuit board 4 to increase the stability of the abutment between the abutment section 5113 and the annular conductive circuit 41 .

[0044] The abutting section 5113 includes a flat abutting portion 51131, and the abutting portion 51131 abuts against the annular conductive circuit 41. In this solution, the abutting section 5113 includes a flat abutting portion 51131, and the abutting portion 51131 is in direct contact with the annular conductive circuit 41. The flat design makes the contact between the abutting portion 51131 and the annular conductive circuit 41 more uniform and stable. Specifically, the flat abutting portion 51131 can provide stable electrical contact, reducing problems such as signal transmission interruption or power loss caused by poor contact. This design is particularly suitable for high-precision and high-power application scenarios. And because the contact between the abutting portion 51131 and the annular conductive circuit 41 is flat, the flat abutting portion 51131 can evenly distribute the pressure on the annular conductive circuit 41, reducing the possibility of local excessive wear. This uniform pressure distribution can effectively extend the service life of the annular conductive circuit 41 and the electrical connector 51. In another embodiment, as Figure 11 shown, the abutting section 5113 is arranged in a U shape with an overall arc shape.

[0045] Furthermore, insertion portions 51111 are provided on both sides of the installation section 5111, and the insertion portions 51111 are inserted into the first circuit board 4 or the second circuit board 5. Insertion portions 51111 are provided on both sides of the installation section 5111, and these insertion portions 51111 can be inserted into corresponding jacks or slots on the first circuit board 4 or the second circuit board 5 to achieve the fixed installation of the electrical connector 51. The insertion portions 51111 are further welded to the first circuit board 4 or the second circuit board 5. By providing the insertion portions 51111 on both sides of the installation section 5111, the electrical connector 51 can be firmly fixed to the first circuit board 4 or the second circuit board 5. This design can effectively prevent the electrical connector 51 from loosening or shifting due to mechanical vibration or external force during use, reducing the problem of poor contact caused by the loosening of the electrical connector 51, thereby improving the reliability of the electrical connection.

[0046] Furthermore, as Figure 7 shown, a plurality of annular conductive circuits 41 are provided. The plurality of annular conductive circuits 41 are concentric and have different radii; at least one electrical connector 51 is correspondingly provided for each annular conductive circuit 41. A plurality of annular conductive circuits 41 are provided. The annular conductive circuits 41 are concentric but have different radii, which can achieve multi-channel signal or power transmission. And at least one electrical connector 51 is correspondingly provided for each annular conductive circuit 41 to ensure stable electrical connection for each annular conductive circuit 41. The plurality of annular conductive circuits 41 and electrical connectors 51 can be respectively used for transmitting power and data signals, etc., which can be set according to specific needs and will not be elaborated here.

[0047] Furthermore, at least two electrical connectors 51 are correspondingly provided for each annular conductive circuit 41. Each annular conductive circuit 41 is provided with at least two electrical connectors 51, which can provide multiple contact points and reduce the problem of electrical connection interruption caused by poor single-point contact. Specifically, there are 6 annular conductive circuits 41, and two electrical connectors 51 are correspondingly provided on each annular conductive circuit 41. At this time, there are 4 connection points with the electrical connector 51 on each annular conductive circuit 41. Specifically, the scheme of the present invention can also increase or decrease the number of electrical connectors 51 according to actual application conditions to control the number of contact points of the electrical connector 51 and provide a more reliable electrical connection. For example, the corresponding electrical connectors 51 of a single electrical connection functional module are arranged in groups, and 6 electrical connectors 51 form 1 group. 1 group or 2 groups can be arranged.

[0048] On the other hand, Figure 3 As shown, the rotating base 2 is provided with an installation cavity 21, and a coil spring 6 is installed in the installation cavity 21; when the data line 3 is stretched, the coil spring 6 is rolled up to store force. The rotating base is provided with an installation cavity 21 for installing the coil spring 6. The coil spring 6 is installed in the installation cavity 21. When the data line 3 is stretched, the coil spring 6 is rolled up to store force; when the data line 3 is released, the coil spring 6 releases energy and drives the rotating base 2 to roll back the data line 3. The rotating base 2 is also provided with a positioning mechanism. When the user stops stretching the data line 3, the positioning mechanism positions the rotating base 2 so that the data line 3 remains at the current stretched length. When the data line 3 is slightly pulled again, the positioning mechanism releases the lock on the rotating base 2, and the rotating base 2 rotates and rewinds the data line 3 under the drive of the coil spring 6. The specific installation of the coil spring 6 and the specific implementation of the positioning mechanism can be implemented by the existing conventional scheme, which will not be described in detail here.

[0049] Furthermore, if Figure 1 As shown, the housing 1 includes a first base shell 11 and a second base shell 12, and the first base shell 11 and the second base shell 12 are mounted in abutment. A wire outlet 13 is provided on the side of the first base shell 11 and the second base shell 12, and one end of the data line 3 is led out from the wire outlet 13. The second circuit board 5 is installed in the first base shell 11, and a window 111 is provided on the side of the first base shell 11 away from the second base shell 12, and the power connection pin 52 of the second circuit board 5 is arranged corresponding to the window 111. By dividing the housing 1 into the first base shell 11 and the second base shell 12, this modular design makes the assembly process simpler and more efficient. The first base shell 11 and the second base shell 12 can be processed and assembled independently, and finally mounted in abutment, which reduces the complexity and error rate in the assembly process. The design of the wire outlet 13 on the side enables the data line 3 to be smoothly led out from the module. The window 111 on the first base shell 11 is arranged corresponding to the power connection pin 52 of the second circuit board 5, which is convenient for connection with external devices.

[0050] Furthermore, if Figure 4As shown, a plurality of stopper plates 112 are provided on the first base shell 11, and the plurality of stopper plates 112 are clamped on the side of the connecting section 5112 of the first electrical connecting arm 511 and the second electrical connecting arm 512 after passing through the second circuit board 5. The stopper plates 112 can not only improve the installation firmness of the second circuit board 5, but also improve the installation stability of the electrical connecting member 51 to avoid loosening during the sliding process. A rotating mounting column 113 is also provided in the first base shell 11, and the rotating base 2 is rotatably mounted on the rotating mounting column 113, and the second base shell 12 is mounted on the rotating mounting column 113 by screws.
