[0010] Optionally, the rotating shaft includes:

[0011] The first shaft segment has one end integrally formed with the outer shell;

[0012] A variable diameter section, which is connected to the other end of the first shaft section;

[0013] The second shaft segment is connected to the side of the variable diameter segment away from the first shaft segment;

[0014] The diameter of the second shaft segment is smaller than that of the first shaft segment, and the diameter of the variable diameter segment gradually decreases from the side closest to the first shaft segment toward the side furthest from the first shaft segment, so as to make the transition between the first shaft segment and the second shaft segment smooth.

[0015] Optionally, the housing includes a first housing and a second housing, the first housing and the second housing being engaged to define an installation space for accommodating the turntable, one end of the rotating shaft being disposed on the first housing, the second housing being provided with a mounting through hole, and the stretchable data cable further including a screw, the screw being inserted into the mounting through hole and the other end of the rotating shaft.

[0016] Optionally, the first housing includes a first edge portion adjacent to the second housing, and the second housing includes a second edge portion disposed opposite to the first edge portion. The first edge portion is provided with one of a strip-shaped rib and a strip-shaped groove, and the second edge portion is provided with the other of a strip-shaped rib and a strip-shaped groove. The strip-shaped rib and the strip-shaped groove are adapted to position the first housing and the second housing.

[0017] Optionally, the first edge portion is further provided with one of the second pin and the second slot, and the second edge portion is further provided with the other of the second pin and the second slot, the second pin and the second slot being adapted to each other, and the height of the second pin being greater than the height of the strip rib.

[0018] Optionally, the interface is provided in two parts, and the two interfaces are respectively connected to the two ends of the data cable.

The rotating shaft passes through the first shaft hole, and the coil spring is installed in the mounting groove. The inner and outer sides of the coil spring are connected to the rotating shaft and the turntable, respectively. Specifically, the stretchable data cable also includes a cover plate, which is installed at one end of the turntable and covers the opening of the mounting groove. The turntable is provided with a second shaft hole, through which the rotating shaft passes. Since the cover plate is installed at the other end of the turntable away from the first shaft hole, and since the turntable is provided with a second shaft hole that cooperates with the rotating shaft, the presence of the cover plate allows the other end of the turntable to be constrained by the rotating shaft. Compared with the prior art that only has a first shaft hole, the rotational stability of the turntable is higher.

[0021] In addition, assembling the stretchable data cable requires sequential assembly steps of the coil spring and the turntable, and assembly steps of the turntable and the housing. Before the assembly of the housing and the turntable is completed, the coil spring may release energy and pop out of the turntable, which is quite dangerous. The cover plate added in this embodiment is placed at the opening of the mounting groove. Therefore, the cover plate can not only improve the rotation stability of the turntable, but also limit the coil spring before the turntable and the housing are assembled, thus improving the safety of product assembly.

[0042] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0043] refer to Figures 1-5 This utility model embodiment provides a stretchable data cable 1000, such as... Figure 1As shown, the stretchable data cable 1000 includes a housing 100, a turntable 200, a data cable 300, and a coil spring 400. A rotating shaft 110 is provided inside the housing 100. One end of the turntable 200 has a mounting groove 210, and the other end has a first shaft hole 220 communicating with the bottom of the mounting groove 210. The rotating shaft 110 passes through the first shaft hole 220 to rotatably connect the turntable 200 to the housing 100. The data cable 300 includes a cable body 310 and an interface 320. The cable body 310 is wound around the turntable 200, and the interface 320 is connected to the end of the cable body 310 and is located outside the housing 100. The coil spring 400 is installed in the mounting groove 210, and its inner and outer sides are connected to the rotating shaft 110 and the turntable 200, respectively. The cover plate 500 is installed at one end of the turntable 200 and covers the opening of the mounting groove 210. The turntable 200 is provided with a second shaft hole 510, and the rotating shaft 110 passes through the second shaft hole 510.

[0044] Firstly, since the cover plate 500 is installed at the other end of the turntable 200 away from the first shaft hole 220, and since the turntable 200 is provided with a second shaft hole 510 that cooperates with the rotating shaft 110, the presence of the cover plate 500 allows the other end of the turntable 200 to be constrained by the rotating shaft 110. Compared with the prior art which only has a first shaft hole 220, the rotational stability of the turntable 200 is higher.

[0045] Secondly, assembling the stretchable data cable 1000 requires sequential assembly steps of the coil spring 400 and the turntable 200, and assembly steps of the turntable 200 and the outer shell 100. Before the assembly of the outer shell 100 and the turntable 200 is completed, the coil spring 400 may release energy and pop out of the turntable 200, which is highly dangerous. The cover plate 500 added in this embodiment is placed at the opening of the mounting groove 210. Therefore, the cover plate 500 can not only improve the rotational stability of the turntable 200, but also limit the coil spring 400 before the turntable 200 and the outer shell 100 are assembled, thus improving the safety of product assembly.

[0046] There are many specific implementation methods for mounting the cover plate 500 on the turntable 200. This embodiment is not limited here. Several specific embodiments are listed below for illustration.

[0047] In Embodiment 1, a first slot 520 is provided at one end of the turntable 200, and a first pin 240 is provided on the side of the cover plate 500 facing the turntable 200. The first pin 240 is adapted to the first slot 520 so that the cover plate 500 is installed at one end of the turntable 200.

[0048] refer to Figures 1-5 In the second embodiment, a first pin 240 is provided at one end of the turntable 200, and a first slot 520 is provided on the side of the cover plate 500 facing the turntable 200. The first pin 240 is adapted to the first slot 520 so that the cover plate 500 is installed at one end of the turntable 200.

[0049] In embodiment three, one end of the turntable 200 is provided with a slot (not shown in the figure), and the cover plate 500 is provided with a buckle (not shown in the figure). The slot and the buckle are adapted to each other so that the cover plate 500 is installed at one end of the turntable 200.

[0050] In embodiment four, one end of the turntable 200 is provided with a buckle, and the cover plate 500 is provided with a slot. The slot and the buckle are adapted to each other so that the cover plate 500 is installed at one end of the turntable 200.

[0051] refer to Figure 4 and Figure 5 In the specific embodiments of the above-mentioned Embodiment 1 and Embodiment 2, multiple first pins 240 are provided, and multiple first slots 520 are provided accordingly. This arrangement can increase the connection stability between the cover plate 500 and the turntable 200.

[0052] In a specific embodiment, the edge of the first pin 240 is provided with a chamfer (not shown in the figure). The chamfer can provide a guiding function when the first pin 240 is inserted into the first slot 520, reduce the difficulty of aligning the first pin 240 and the first slot 520, and facilitate the assembly of the cover plate 500 and the turntable 200.

[0053] refer to Figure 4 and Figure 5 In some embodiments, one end of the turntable 200 is provided with a receiving groove 230, and the cover plate 500 is installed in the receiving groove 230.

[0054] This embodiment provides a receiving groove 230 at one end of the turntable 200 to accommodate the cover plate 500. This reduces the overall thickness of the cover plate 500 after it is installed on the turntable 200, thereby reducing the thickness and volume of the stretch data cable 1000. This also makes it easier to transport, store, and carry the stretch data cable 1000.

[0055] refer to Figure 6 and Figure 7 In some embodiments, the rotating shaft 110 includes a first shaft segment 111, a variable diameter segment 112, and a second shaft segment 113. One end of the first shaft segment 111 is integrally formed with the housing 100, the variable diameter segment 112 is connected to the other end of the first shaft segment 111, and the second shaft segment 113 is connected to the side of the variable diameter segment 112 away from the first shaft segment 111. The diameter of the second shaft segment 113 is smaller than that of the first shaft segment 111, and the diameter of the variable diameter segment 112 gradually decreases from the side closest to the first shaft segment 111 towards the side away from the first shaft segment 111, so that the transition between the first shaft segment 111 and the second shaft segment 113 is smooth.

[0056] Specifically, when assembling the stretchable data cable 1000, the rotating shaft 110 needs to be inserted into the assembly formed by assembling the cover plate 500 and the turntable 200. In order to reduce the difficulty of aligning the rotating shaft 110 with the assembly, the rotating shaft 110 in this embodiment is provided with a second shaft segment 113 with a smaller diameter. Since the second shaft segment 113 has a smaller diameter, when assembling the rotating shaft 110, the second shaft segment 113 can be inserted into the assembly first, which can reduce the difficulty of aligning the rotating shaft 110 with the assembly.

[0057] Since the diameter of the second shaft segment 113 is smaller than that of the first shaft segment 111, if the second shaft segment 113 is directly connected to the first shaft segment 111, a step will be formed at the connection point. This step can easily cause the components to abut against each other during assembly, resulting in assembly difficulties. To solve this technical problem, this embodiment provides a variable diameter segment 112. The diameter of the variable diameter segment 112 gradually decreases from the side closest to the first shaft segment 111 towards the side away from the first shaft segment 111, so that the transition between the first shaft segment 111 and the second shaft segment 113 is smooth. A smooth transition means that no step is formed, which can improve the smoothness of assembly.

[0058] In some embodiments, the housing 100 includes a first housing 120 and a second housing 130, which are engaged to define an installation space (not shown) for accommodating the turntable 200. One end of the rotating shaft 110 is disposed on the first housing 120, and the second housing 130 is provided with a mounting through hole 131. The data cable 1000 also includes a screw (not shown) inserted into the mounting through hole 131 and the other end of the rotating shaft 110.

[0059] In this embodiment, one end of the rotating shaft 110 is disposed on the first housing 120, and the other end of the rotating shaft 110 is connected to the second housing 130 through a screw. Therefore, both ends of the rotating shaft 110 are constrained. Compared with the prior art where the other end of the rotating shaft 110 is not connected to the second housing 130, the rotating shaft 110 has higher structural strength and is less prone to deformation under the influence of external forces. As a result, the rotational stability of the turntable 200 is also improved.

[0060] In a specific embodiment, the first housing 120 includes a first edge portion 121 adjacent to the second housing 130, and the second housing 130 includes a second edge portion 132 disposed opposite to the first edge portion 121. The first edge portion 121 is provided with a strip groove 1211, and the second edge portion 132 is provided with a strip rib 1321. The strip rib 1321 and the strip groove 1211 are adapted to position the first housing 120 and the second housing 130.

[0061] By implementing this embodiment, when assembling the first housing 120 and the second housing 130, the strip-shaped rib 1321 and the strip-shaped groove 1211 can be used to position the first housing 120 and the second housing 130, ensuring accurate alignment of the first housing 120 and the second housing 130. After positioning, the screws can be installed to complete the assembly of the first housing 120 and the second housing 130. The reason for using the strip-shaped rib 1321 is that the strip-shaped rib 1321 has high structural strength and is not easily damaged under external forces.

[0062] Optionally, the strip rib 1321 is disposed on the first edge portion 121, and the strip groove 1211 is disposed on the second edge portion 132. The strip rib 1321 and the strip groove 1211 are adapted to position the first housing 120 and the second housing 130.

[0063] By implementing this embodiment, when assembling the first housing 120 and the second housing 130, the strip-shaped rib 1321 and the strip-shaped groove 1211 can be used to position the first housing 120 and the second housing 130, ensuring accurate alignment of the first housing 120 and the second housing 130. After positioning, the screws can be installed to complete the assembly of the first housing 120 and the second housing 130. The reason for using the strip-shaped rib 1321 is that the strip-shaped rib 1321 has high structural strength and is not easily damaged under external forces.

[0064] In some embodiments, the first edge portion 121 is further provided with a second slot 1212, and the second edge portion 132 is further provided with a second pin 1323. The second pin 1323 is adapted to the second slot 1212, and the height of the second pin 1323 is greater than the height of the strip rib 1321.

[0065] Specifically, it is difficult to align the strip-shaped rib 1321 with the strip-shaped groove 1211. To solve this technical problem, this embodiment adds a second slot 1212 to the first edge portion 121 and a second pin 1323 to the second edge portion 132. The second pin 1323 and the second slot 1212 are adapted to each other, and the height of the second pin 1323 is greater than the height of the strip-shaped rib 1321. With this arrangement, before the strip-shaped rib 1321 and the strip-shaped groove 1211 are engaged, the second pin 1323 and the second slot 1212 will engage first, thereby pre-positioning the first housing 120 and the second housing 130, so that the strip-shaped rib 1321 can be placed into the strip-shaped groove 1211 later.

[0066] It is worth mentioning that the structural strength of the second pin 1323 is not as good as that of the strip rib 1321. Therefore, although the second pin 1323 can cooperate with the second slot 1212 to position the first housing 120 and the second housing 130, in order to ensure the connection strength between the first housing 120 and the second housing 130, this embodiment still provides the strip rib 1321 and the strip groove 1211.

[0067] Optionally, the second pin 1323 is disposed on the first edge portion 121, and the second slot 1212 is disposed on the second edge portion 132. The second pin 1323 and the second slot 1212 are adapted to each other, and the height of the second pin 1323 is greater than the height of the strip rib 1321.

[0068] Specifically, it is difficult to align the strip-shaped rib 1321 with the strip-shaped groove 1211. To solve this technical problem, this embodiment adds a second pin 1323 to the first edge portion 121 and a second slot 1212 to the second edge portion 132. The second pin 1323 and the second slot 1212 are adapted to each other, and the height of the second pin 1323 is greater than the height of the strip-shaped rib 1321. With this arrangement, before the strip-shaped rib 1321 and the strip-shaped groove 1211 are engaged, the second pin 1323 and the second slot 1212 will engage first, thereby pre-positioning the first housing 120 and the second housing 130, so that the strip-shaped rib 1321 can be placed into the strip-shaped groove 1211 later.

[0069] It is worth mentioning that the structural strength of the second pin 1323 is not as good as that of the strip rib 1321. Therefore, although the second pin 1323 can cooperate with the second slot 1212 to position the first housing 120 and the second housing 130, in order to ensure the connection strength between the first housing 120 and the second housing 130, this embodiment still provides the strip rib 1321 and the strip groove 1211.

[0070] In some embodiments, there are two interfaces 320, which are respectively connected to the two ends of the data cable 300.

[0071] This embodiment demonstrates a double-sided stretchable data cable 1000. When in use, the two interfaces 320 of the data cable 300 can be connected to a computer and a power device, a power adapter and a power device, etc. This embodiment does not limit the scope of the data cable 300.

[0072] In some embodiments, the stretchable data cable 1000 further includes an electrical connection component 600, which includes a first PCB board 610 and a second PCB board 620. The first PCB board 610 is disposed on the turntable 200 and has a conductive ring 621. The second PCB board 620 is disposed on the housing 100 and has a conductive contact 611. The conductive ring 621 contacts the conductive contact 611. The second PCB board 620 also has solder gold fingers 622 that are electrically connected to the conductive contact 611.

[0073] Specifically, the soldering gold finger 622 and the conductive contact 611 are both located on the second PCB board 620, and the conductive ring 621 that contacts the conductive contact 611 is located on the first PCB board 610. The end of the wire 310 away from the interface 320 is connected to the first PCB board 610. Therefore, the soldering gold finger 622 can conduct electricity with the wire 310 through the conductive contact 611 and the conductive ring 621.

[0074] This embodiment illustrates a single-sided stretchable data cable 1000, which has an interface 320 at only one end, suitable for pre-installation in electronic products such as power adapters, power banks, and power strips. Exemplarily, the soldering gold fingers 622 can be used to solder wires, connecting the wires to power supply components inside the electronic product to supply power to the stretchable data cable 1000.

[0075] Optionally, the conductive ring 621 is disposed on the second PCB board 620, and the conductive contact 611 is disposed on the first PCB board 610. The conductive ring 621 is in contact with the conductive contact 611.

[0076] Specifically, the soldering gold finger 622 and the conductive ring 621 are both disposed on the second PCB board 620, and the conductive contact 611 that contacts the conductive ring 621 is disposed on the first PCB board 610. The end of the wire 310 away from the interface 320 is connected to the first PCB board 610. Therefore, the soldering gold finger 622 can conduct electricity with the wire 310 through the conductive contact 611 and the conductive ring 621.

[0077] This embodiment illustrates a single-sided stretchable data cable 1000, which has an interface 320 at only one end, suitable for pre-installation in electronic products such as power adapters, power banks, and power strips. Exemplarily, the soldering gold fingers 622 can be used to solder wires, connecting the wires to power supply components inside the electronic product to supply power to the stretchable data cable 1000.

[0078] In some embodiments, the conductive contact 611 is an elastic conductive contact. Since the first PCB board 610 is mounted on the turntable 200 and the second PCB board 620 is mounted on the housing, the first PCB board 610 will rotate relative to the second PCB board 620 when the turntable 200 rotates. The conductive contact 611 and the conductive ring 621 will generate friction. In order to avoid poor contact due to long-term friction between the conductive contact 611 and the conductive ring 621, this embodiment sets the conductive contact 611 as an elastic conductive contact 611. In this way, the elasticity can ensure good contact between the conductive contact 611 and the conductive ring 621.

[0079] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
