[0042] The cable reel 4 includes an outer shell 41, which provides external protection and support for the entire reel. It encloses the internal components, ensuring they are protected from the external environment during use. A rotatable cable reel 42 is housed within the outer shell 41. This reel 42 is one of the reel's core components, and the charging cable 5 is wound around it. When the user stretches the charging cable 5, the reel 42 rotates, releasing the desired length of cable. When charging is complete, a coil spring automatically retracts the reel 42, retracting the charging cable 5. A coil spring is housed within the reel 42, one end of which is fixedly connected to the reel 42 and the other end to the outer shell 41. When the charging cable 5 is stretched, the coil spring stretches, storing elastic potential energy. When the external force is removed, the coil spring releases this elastic potential energy, causing the reel 42 to rotate in the opposite direction, automatically retracting the charging cable 5. The cable reel 42 is equipped with a circuit board 1 44, and a circular circuit board 2 45 is mounted on the inner wall of the outer shell 41. Circuit boards 1 44 and 2 45 are positioned facing each other and play a key role in the electrical connection of the charging cable 5. A spring clip 46 is positioned between circuit boards 1 44 and 2 45. One end of the spring clip 46 is fixedly connected to circuit board 1 44, while the other end of the spring clip 46 elastically contacts circuit board 2 45. This spring clip 46 establishes a reliable electrical connection between circuit boards 1 44 and 2 45. Since the cable reel 42 rotates continuously during use, the elastic contact of the spring clip 46 ensures a stable electrical connection at various rotation angles. A circular power connection area 47 is provided on circuit board 2 45, corresponding to the spring clip 46. This power connection area 47 is designed to better cooperate with the rotating spring clip 46, ensuring a stable and reliable electrical connection. One end of the charging cable 5 is electrically connected to the circuit board 1 44 , and also includes an external wire 48 electrically connected to the circuit board 2 45 , and the external wire 48 is electrically connected to the circuit board 3 11 .

[0043] The outer shell 41, the winding drum 42, and the circuit board 45 are coaxially arranged, and a plurality of spring clips 46 are provided. The plurality of spring clips 46 are arranged at radial intervals on the winding drum 42. A plurality of power connection areas 47 are provided, and the plurality of power connection areas 47 are arranged corresponding to the plurality of spring clips 46. When the winding drum 42 rotates, the spring clips 46 rotate along the corresponding power connection areas 47 to maintain electrical connection.

[0044] One end of the charging cable 5 is electrically connected to the circuit board 1 44. When a user uses the charging cable 5 to charge a device such as a mobile phone, current is transmitted to the circuit board 1 44 through the charging cable 5.

[0045] The first circuit board 44 and the second circuit board 45 are electrically connected via a spring 46. The elastic contact of the spring 46 enables a stable current transmission between the first circuit board 44 and the second circuit board 45.

[0046] The second circuit board 45 and the third circuit board 11 are electrically connected via an external wire 48. The external wire 48 transmits the current on the second circuit board 45 to the third circuit board 11.

[0047] This makes one end of the charging line 5 electrically connected to the circuit board 3 11. In this way, a complete circuit connection from the power supply of the socket to the charging line 5 is achieved, providing a reliable power supply for charging devices such as mobile phones.

[0048] In summary, the cord reel structure of the USB socket is cleverly designed. Through the coordinated action of various components, the stretchable and automatic retraction functions of the charging cable are realized, while ensuring the stability and reliability of the circuit connection.

[0049] Two cord reels 4 are provided, a design that provides users with more charging options and convenience. The two cord reels can simultaneously meet the charging needs of multiple devices, or if one cord reel fails, the other can still function normally, improving the reliability of the socket. Circuit board three 11 is disposed between the two cord reels 4. This layout can make the circuit connection more compact and reasonable, reduce the length and complexity of the line, and improve the stability and reliability of the circuit. At the same time, placing circuit board three 11 in the middle position also facilitates connection with the two cord reels, enabling power distribution and transmission.

[0050] Plug 6 comes in a variety of styles, including Type-C, USB, Micro, and Lightning. This diverse design accommodates the charging needs of a wide range of devices, from new smartphones and tablets to traditional electronic devices. Users no longer need to carry multiple charging cables and plugs; they can simply use the included plug to charge a variety of devices, greatly improving charging convenience and versatility.

[0051] The sidewall of the housing 3 is provided with a socket 14 for connecting to the circuit board 3 11. This socket serves to securely connect the circuit board 3 11. This ensures that the circuit board 3 11 is securely mounted within the housing 3, preventing it from loosening or shifting during use. The socket design facilitates installation and removal of the circuit board 3 11, making it easier to repair and replace.

[0052] Connected to circuit board three 11 are power terminals 15, which are used to electrically connect to the wall's electrical grid. When the outlet is mounted on the wall, terminals 15 connect to the wall's electrical grid, directing power to the outlet. This control and distribution by circuit board three 11 provides a stable power supply to the cord reel 4 and the socket 12, enabling charging of devices such as mobile phones.

[0053] The housing 3 includes a mounting slot 16 for the cable reel 4. The design of the mounting slot 16 allows the cable reel 4 to be accurately positioned within the housing 3, ensuring proper operation. The mounting slot 16 provides stable support and fixation for the cable reel 4, preventing it from shaking or shifting during use. Furthermore, the mounting slot 16 provides protection from external impacts and damage.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
