[0055] Example

[0056] See Figure 1 and Figure 2 In this embodiment, a data cable capable of single-side retraction and retraction is provided, comprising a first retraction and retraction module 10, a second retraction and retraction module 20, a first wire 30, and a second wire 40. For ease of description, the data cable capable of single-side retraction and retraction is hereinafter referred to as a data cable.

[0057] The first winding and unwinding module 10 includes a first winding device 11 and a first circuit board 12 that are connected to each other in a synchronous rotation.

The second winding and unwinding module 20 includes a second winding device 21 and a second circuit board 22 that are connected to each other in a synchronous rotation. The second winding device 21 is used to wind a second wire 40, and the second circuit board 22 is electrically connected to the second wire 40.

[0058] The first and second winding devices 11 and 21 are rotatable relative to each other, and the first and second circuit boards 12 and 22 are rotatably electrically connected. The first and second circuit boards 12 and 22 are always electrically connected: when the first and second circuit boards 12 and 22 remain relatively stationary, they are electrically connected; and when the first and second circuit boards 12 and 22 are relatively rotating, they are also electrically connected.

[0059] When the first wire 30 is wound or unwound, the first winder 11 and the first circuit board 12 both rotate synchronously; when the second wire 40 is wound or unwound, the second winder 21 and the second circuit board 22 both rotate. Because the first winder 11 and the second winder 21 can rotate relative to each other, and the first circuit board 12 and the second circuit board 22 are rotatably electrically connected, the first winder 11 can rotate independently of the second winder 21, and the first circuit board 12 can also rotate independently of the second circuit board 22. Because the first circuit board 12 and the second circuit board 22 are rotatably electrically connected, when the first winder 11 and the second winder 21 rotate relative to each other, the first wire 30 and the second wire 40 can always maintain an electrical connection, thereby ensuring that electrical energy and / or data are transmitted through the first wire 30 and the second wire 40. The first wire 30 and the second wire 40 are independent of each other, that is, when one of the first wire 30 or the second wire 40 is unwound or reeled, the other can maintain its current state without being affected.

A second protrusion 2122 is disposed within the second assembly slot 212. The outer end of the second spring 2121 is sheathed over the second protrusion 2122, thereby positioning and constraining the outer end of the second spring 2121.

[0075] There are multiple conductive rings 223 that are concentrically arranged, and the geometric center of the conductive rings 223 is located on the rotation axis of the second circuit board 22 .

[0076] The conductive contact 1232 corresponds to the conductive ring 223 and maintains electrical contact with the corresponding conductive ring 223. Specifically, the distance between the conductive contact 1232 and the rotation axis of the second circuit board 22 is equal to the radius of the corresponding conductive ring 223.

[0087] The cover 71 is disposed over the first assembly slot 112, thereby covering the first mainspring 1121 and thereby confining the first mainspring 1121 within the first assembly slot 112. The cover 71 and the first winder 11 can be fixedly connected by means of a snap connection, a buckle connection, or a screw connection. A central through-hole is defined in the cover 71, and the first connecting shaft 611 on the first housing 61 is rotatably inserted into the central through-hole of the cover 71.

[0088] The cover 71 has a protrusion 711 on its end surface. The outer periphery of the protrusion 711 is provided with a plurality of grooves 7111 arranged in a circular array.

The first sleeve portion 741 is sleeved onto the first boss 614, and the second sleeve portion 742 is sleeved onto the second boss 615, thereby achieving a fixed connection between the spring clip 74 and the first housing 61. The spring clip 74 and the swinging member 72 can be fixedly connected by bonding, snapping, or other means. When the swinging member 72 deflects and leaves its initial position, the spring clip 74 is used to provide an elastic restoring force to the swinging member 72, thereby driving the swinging member 72 to return to its original position.

[0091] During use, when the user needs to pull the first wire 30 out of the housing 60, the user can pull the first connector end 32 of the first wire 30 to drive the first winder 11 to rotate, wherein as the first winder 11 rotates, the cover 71 will rotate synchronously. After the cover 71 rotates, the swing member 72 will deflect, and the protrusion 721 of the swing member 72 will disengage from the currently embedded groove 7111. At the same time, the spring 74 will give the swing member 72 an elastic reset force. When the user releases his hand, the first spring 1121 will drive the first winder 11 to rotate and drive the stretched first wire 30 to reel, but at this time the spring 74 drives the swing member 72 to reset, and the first protrusion 722 on the swing member 72 abuts against the abutment groove 731 of the rotating wheel 73, thereby preventing the swing member 72 from rotating. At the same time, the protrusion 721 of the swing member 72 swings through a certain angle, and the protrusion 721 stops in a groove 7111 on the cover body 71, so that the cover body 71 stops rotating, and finally the first winder 11 stops rotating, which plays a role of locking and positioning.

[0092] When the user needs to rewind the first wire 30, they pull the portion of the first wire 30 that has escaped the housing 60, thereby rotating the cover 71. As the cover 71 rotates, the protrusion 721 on the swinging member 72 disengages from the recess 7111 in which it is currently embedded and deviates from its current position. At this point, the spring 74 applies an elastic restoring force to the swinging member 72. When the user releases their grip, the first spring 1121 gradually returns to its original position under its own elastic force. Simultaneously, the spring 74 drives the swinging member 72 back to its original position, and the second protrusion 723 on the swinging member 72 engages with the tooth groove 732 of the rotating wheel 73. The tooth groove 732 is an arc-shaped groove, and the tooth groove 732 and the second protrusion 723 cannot achieve self-locking. Therefore, when the angle swung by the protrusion 721 on the swinging member 72 is greater than the angle swung by the protrusion 721 during unwinding, and the protrusion 721 stops outside the groove 7111 of the cover body 71, the cover body 71 will rotate, and finally, under the action of the first spring 1121, the first wire 30 is wound into the housing 60.

[0093] In this embodiment, the first positioning assembly 70 and the second positioning assembly 80 have the same structure. The cover of the second positioning assembly 80 is fixedly connected to the second winder. The swinging member and the rotating wheel of the second positioning assembly 80 are both rotatably connected to the second housing 62. The spring of the second positioning assembly 80 is mounted on the second housing and connected to the swinging member of the second positioning assembly 80. The operating principle of the second positioning assembly 80 is similar to that of the first positioning assembly 70.

[0094] In other embodiments, the first positioning assembly 70 and the second positioning assembly 80 may also adopt other structures in existing designs, which will not be described in detail herein.
