[0051] Please see Figures 1-3 As shown, in one embodiment of this utility model, a retractable data cable includes a housing 10, a reel 20, a first data cable 40, a second connection interface 90, and a connector. The connector is disposed on the housing 10. In this embodiment, the connector is an interface mounting base 54 disposed on the first housing portion 14. The housing 10 includes a first housing portion 14 and a second housing portion 15 disposed opposite each other along the thickness direction, and a side housing portion 16 connected between the first housing portion 14 and the second housing portion 15. A support portion 60 is provided on the surface of the first housing portion 14 (in other embodiments, the support portion 60 may also be disposed on the first housing portion 14). The second shell portion 15 (not limited here) has a cavity 11 formed inside the shell 10. A cable passage 12 communicating with the cavity 11 is provided on the side shell portion 16. A cable reel 20 is rotatably disposed within the cavity 11. The first data cable 40 includes a cable body 41 and a first connecting interface 42 at one end of the cable body 41. The other end of the cable body 41 passes through the cable passage 12 into the cavity 11 and is wound around the cable reel 20. A second connecting interface 90 is disposed on the shell 10 and mounted on the interface mounting base 54. The second connecting interface 90 is electrically connected to the cable body 41 within the cavity 11. When not in use, the cable body 41 is wound around the cable reel 20. The cable reel 20 can rotate to wind up or unwind the cable body 41. This retractable data cable is easy to store and carry. The cable body 41 can be wound around the cable reel 20 without tangling itself or other items. When the retractable data cable is needed, simply pull out the cable body 41. It is convenient to use.

[0052] The first connection interface 42 can be connected to an electronic device (such as a mobile phone, tablet computer, etc.), and the second connection interface 90 can be connected to a charging adapter. The first connection interface 42 and the second connection interface 90 can be one of the following interface types: USB Type-C, USB Type-A, Lightning, Micro USB, etc. For example, the second connection interface 90 is a USB Type-C interface (e.g.,...). Figure 2As shown), when the second connection interface 90 is inserted into the charging head, the interface mounting base 54 connected to the second connection interface 90 is indirectly connected to the charging head. The interface mounting base 54 is disposed on the first housing 14, and the support part 60 is disposed on the first housing 14. The support part 60 is connected to the charging head, that is, the interface mounting base 54, as a connector, can connect the support part 60 disposed on the first housing 14 to an external device. The housing 10 and the charging head temporarily form an assembly. When the charging head is plugged into a wall socket in the room, the housing 10 is not suspended when connected to the charging head, so there will be no inconvenience caused by the weight of the housing 10 pulling the cable 41 when it is suspended in the air, which would reduce the user experience. Of course, in other embodiments, the first connection interface 42 can be used to connect to the charging head, and the second connection interface 90 can be used to connect to an electronic device. It is not limited that the first connection interface 42 must be connected to an electronic device. Since the thickness of the housing 10 is the smallest relative to the length and width of the housing 10 (e.g., Figure 1 As shown, the housing 10 is connected to an external device (such as a charging head) along the thickness direction of the housing 10 at the support 60, so the overall shape is not obtrusive and the aesthetics are good.

[0053] Please see Figure 4 As shown, in one embodiment of this utility model, the connector 50 includes an elastic strap. When the elastic strap is connected to the housing 10, there is a placement space 52 between them for placing an external device. After the elastic strap deforms elastically, the external device can be placed in the placement space 52. The elastic force of the elastic strap binds and locks the relative position of the housing 10 and the external device, making them form a whole. In this embodiment, the elastic strap is integrally formed. In other embodiments, the elastic strap can be designed to include multiple strap segments connected in sequence. In this embodiment, the connector 50 uses the strap to bind and lock the relative position of the housing 10 and the external device, so that the support part 60 of the first housing part 14 is connected to the external device. In this document, the connector specifically uses a strap or an interface mounting base 54 to connect the support part 60 to the external device. In other embodiments, the connector can also use a buckle, magnetic attraction, or Velcro to connect the support part 60 to the external device. The specific connection structure of the connector is not limited; it is only necessary to achieve the connection between the support part 60 and the external device through a mechanical connection structure.

[0054] For further optimization of the solution, please refer to [link / reference]. Figure 4As shown, the binding surface of the elastic strap is provided with a plurality of protrusions and recesses 51. The length direction of the plurality of protrusions and recesses 51 extends along the width direction of the elastic strap, and the plurality of protrusions and recesses 51 are spaced apart along the length direction of the elastic strap. In other embodiments, the length direction of the plurality of protrusions and recesses 51 may extend along the length direction of the elastic strap, and the plurality of protrusions and recesses 51 are spaced apart along the width direction of the elastic strap. By providing the protrusions and recesses 51, the binding surface of the elastic strap can increase the friction coefficient of the binding surface and improve the binding effect.

[0055] In a further optimized design, the elastic strap is provided with multiple air chambers that can deform elastically. These air chambers are spaced apart along the length of the elastic strap. By providing deformable air chambers, the binding elasticity of the elastic strap is increased, and the elastic strap can generate a more uniform and adaptive elastic force distribution according to the shape and size of the object being bound during the binding process, thereby improving the binding effect.

[0056] For further optimization of the solution, please refer to [link / reference]. Figure 4 As shown, the first shell portion 14 is provided with a first mounting portion 140, and the two ends of the elastic strap are respectively provided with second mounting portions 53 that are detachably connected to the first mounting portion 140. In other embodiments, the first mounting portion 140 may be provided on the side shell portion 16, which is not limited here. The shell 10 and the elastic strap are detachably connected through the first mounting portion 140 and the second mounting portion 53, which facilitates the installation and removal of the elastic strap. Of course, the shell 10 and the elastic strap may also be fixedly connected.

[0057] Please see Figure 4 As shown, in one embodiment of this utility model, the retractable data cable also includes a second data cable 80. One end of the second data cable 80 is provided with a connector body 81, and a second connection interface 90 is provided on the connector body 81. The other end of the second data cable 80 is electrically connected to the cable body 41 in the receiving cavity 11. The side shell 16 is provided with a placement groove 160 for placing the connector body 81. When the second connection interface 90 is not in use, the second connection interface 90 can be stored in the placement groove 160 of the side shell 16, so that the product looks neat and beautiful when idle, avoiding the messiness and damage risk caused by exposed interfaces, and improving the durability and service life of the interface.

[0058] Please see Figures 1-2 As shown, in one embodiment of the present invention, the support portion 60 further includes a rubber pad, which is disposed on the first shell portion 14. In other embodiments, the rubber pad may be disposed on the second shell portion 15. When the support portion 60 of the first shell portion 14 is connected to an external device, the rubber pad between the two has resistance to prevent relative movement between the shell 10 and the external device, making it less likely for the shell 10 and the external device to separate, thereby improving the connection stability between the shell 10 and the external device.

[0059] For further optimization of the solution, please refer to [link / reference]. Figures 1-2 As shown, in one embodiment of this utility model, the connector further includes a rotating shaft 70 connected to the interface mounting base 54. The first housing portion 14 is provided with a storage groove 141, and the rotating shaft 70 is inserted into a blind mounting hole on the side wall of the storage groove 141. The second connecting interface 90 rotates via the rotating shaft 70 to fold itself or protrude from the storage groove 141. When the second connecting interface 90 is folded and stored in the storage groove 141 (e.g. Figure 1 As shown), the second connection interface 90 is not connected to an external device. When the second connection interface 90 rotates to protrude itself from the housing 10, the second connection interface 90 can extend along the thickness direction of the housing 10 (e.g., Figure 2 As shown in the figure, at this time, the second connection interface 90 has been switched to the waiting state before connecting to the external device.

[0060] For further optimization of the solution, please refer to [link / reference]. Figure 5 As shown, the connector 50 also includes a rotating shaft 70 connected to the interface mounting base 54. A storage groove 141 is provided in the first housing 14. Each of the two oppositely arranged side walls in the storage groove 141 is provided with a sliding groove 13. The two ends of the rotating shaft 70 correspond one-to-one with the two sliding grooves 13 and are inserted into the sliding grooves 13. The rotating shaft 70 can slide in the sliding grooves 13, that is, the position of the second connection interface 90 on the housing 10 to be connected can be adjusted, so as to facilitate the movement of the second connection interface 90 to be aligned with the external device and connected.

[0061] For further optimization of the solution, please refer to [link / reference]. Figure 5 As shown, in one embodiment of this utility model, the connector 50 further includes a rotating shaft 70 connected to the interface mounting base 54. To facilitate conductor installation, the rotating shaft 70 has a wire-passing channel (not shown). A connector circuit board is provided inside the second connection interface 90. One end of the connector circuit board is electrically connected to one end of the interface mounting base 54. The conductor electrically connected to the wire 41 passes through the wire-passing channel and is then electrically connected to the other end of the interface mounting base 54. In this embodiment, the wire-passing channel inside the rotating shaft 70 not only greatly facilitates the installation and arrangement of the conductor but also effectively solves the common problems of conductor entanglement and interference with other cables in traditional data cables. More specifically, the second connection interface 90 is equipped with a connector circuit board, one end of which is electrically connected to one end of the interface mounting base 54. The conductor electrically connected to the wire 41 passes through the wire-passing channel and is finally connected to the other end of the interface mounting base 54. The wire-passing channel allows the conductor to pass smoothly during the connection process, avoiding conductor fatigue damage caused by frequent bending and twisting, thereby significantly improving the service life of the conductor. Meanwhile, the presence of the cable passage ensures the stability of the conductor during the connection process, reduces signal transmission interruptions or instability that may be caused by external interference, and further improves the overall performance and reliability of the data cable.

[0062] For further optimization of the solution, please refer to [link / reference]. Figure 3 As shown, the interface mounting base 54 is provided with electrical contacts that are electrically connected to the wire body 41. The second connection interface 90 is provided with a probe connector. When the second connection interface 90 is installed in the interface mounting base 54, the probe connector (such as a PogoPin spring connector) is electrically connected after contacting the electrical contacts. The second connection interface 90 can be directly unplugged and put into the slot provided in the housing 10. If it is needed, the second connection interface 90 can be plugged back in.

[0063] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model shall be determined by the protection scope of the claims.
