The second connecting plate 220 can be fixed to the side of the turntable body 210 facing the upper cover 121 by gluing or screwing. An axial hole matching the rotating shaft 111 is arranged in the middle of the turntable body 210 and the second connecting plate 220. The rotating shaft 111 is passed through the axial hole, and the turntable can rotate around the rotating shaft 111 in a clockwise direction and a counterclockwise direction.

[0060] See attached Figure 2In the embodiment of the present application, the connecting wire 300 includes a first wiring harness 310, a second wiring harness 320, a first connection connector 330 and a second connection connector 340. The first connection connector 330 and the second connection connector 340 are located outside the housing 100, which can be a USB connector, a TYPE-C connector or a Lightning connector, etc., and those skilled in the art can configure them as needed. The two ends of the first wiring harness 310 are respectively connected to the first connection connector 330 and the housing 100, and the two ends of the second wiring harness 320 are respectively connected to the second connection connector 340 and the turntable. The housing 100 is provided with wire holes corresponding to the first wiring harness 310 and the second wiring harness 320, and the first wiring harness 310 and the second wiring harness 320 are respectively inserted into the corresponding wire holes, and the first wiring harness 310 and the second wiring harness 320 are conductively connected. Specifically, the end of the first wiring harness 310 away from the first connection connector 330 can be connected to the first connecting plate 122 by means such as welding, and is conductively connected to a plurality of elastic conductive members 123. The first wiring harness 310 includes a plurality of wire cores, each of which is connected to an elastic conductive member 123. The elastic conductive member 123 may be a metal spring, a spring thimble or other suitable elastic member capable of conducting electricity. A through hole 213 is provided on the turntable body 210, and one end of the second wiring harness 320 away from the second connection joint 340 may be connected to the second connecting plate 220 by passing through the through hole 213 in a manner such as welding. The second connecting plate 220 is provided with a plurality of coaxial annular conductive portions 221, wherein the axis thereof is consistent with the central axis of the rotating shaft 111 on the bottom shell 110, and the second wiring harness 320 is conductively connected to the plurality of annular conductive portions 221. The second wiring harness 320 includes a plurality of wire cores, each of which is connected to an annular conductive portion 221, and the annular conductive portion 221 may be an annular copper sheet or other annular conductive metal sheet. During the rotation of the turntable, the multiple elastic conductive members 123 are always in contact with the multiple annular conductive parts 221, so that the first wire harness 310 and the second wire harness 320 are always in conductive connection through the elastic conductive members 123 and the annular conductive parts 221 during the rotation of the turntable. In some other embodiments, multiple annular conductive parts 221 connected to the first wire harness 310 may be provided on the first connecting plate 122, and multiple elastic conductive members 123 connected to the second wire harness 320 may be provided on the second connecting plate 220. In some other embodiments, the turntable may only include the turntable body 210 but not the second connecting plate 220, and the above-mentioned annular conductive parts 221 or elastic conductive members 123 are provided on the side of the turntable body 210 facing the upper cover 121.

[0061] See attached Figure 2In the embodiment of the present application, the second wire harness 320 is wound on the turntable body 210 from the inside to the outside along the first direction with the rotating shaft 111 as the center. Since the end of the second wire harness 320 away from the second connecting connector 340 is fixed to the second connecting plate 220 of the turntable, when the wound second wire harness 320 is pulled out from the accommodation space, the second wire harness 320 can drive the turntable to rotate along the first direction. In the embodiment of the application, the data cable also includes a decorative piece 350, and the second wire harness 320 is inserted into the decorative piece 350. The decorative piece 350 is detachably fixed to the housing 100 and is located at the wire hole on the housing 100 corresponding to the second wire harness 320.

[0062] See attached Figure 3 In the embodiment of the present application, the coil spring 410 is located in the accommodation space, and the two ends of the coil spring 410 are connected to the housing 100 and the turntable, respectively. Specifically, the coil spring 410 is telescopically fixed to the bottom housing 110 through the coil spring cover plate 420, and the first end of the coil spring 410 (that is, the end located inside the coil spring 410) can be fixed to the rotating shaft 111 of the bottom housing 110 by means such as clamping, and the second end of the coil spring 410 (that is, the end located inside the coil spring 410) can be fixed to the turntable body 210 by means such as clamping. When the second wire harness 320 is pulled out from the accommodating space and the second wire harness 320 drives the turntable to rotate in the first direction, the turntable body 210 drives the second end of the coil spring 410 to move, so that the coil spring 410 is in a stretched state; when the pulled out second wire harness 320 is released, the coil spring 410 can drive the turntable body 210 to rotate in a second direction opposite to the first direction through its own elastic force, so that the pulled out second wire harness 320 is rewound on the turntable. After the pulled out second wire harness 320 is rewound on the turntable, the second wire harness 320 returns to the initial state of being completely wound on the turntable. In some other embodiments, the coil spring 410 can also be replaced with an elastic band or other suitable elastic member that can drive the turntable to rotate in the second direction through its own elastic force.

[0063] The limit assembly is located in the accommodating space, and the limit assembly is used to limit the rotation of the turntable in the second direction when the second wire harness 320 is initially drawn out and released, so that the second wire harness 320 remains drawn out. When the second wire harness 320 is drawn out and released again, the restriction on the rotation of the turntable is released, and the turntable can rotate in the second direction driven by the winding spring 410, so that the drawn out second wire harness 320 can be rewound on the turntable. It should be noted that the initial withdrawal mentioned here refers to the withdrawal of the second wire harness 320 when the second wire harness 320 is completely wound on the turntable. When the drawn out second wire harness 320 is rewound on the turntable, the second wire harness 320 returns to the initial state of being completely wound on the turntable. In this case, re-drawing the second wire harness 320 is regarded as the initial withdrawal. That is to say, when the second wire harness 320 is continuously pulled out and released when it is completely wound on the turntable, the first pulling out and releasing is the initial pulling out and releasing, and the second wire harness 320 remains pulled out; the second pulling out and releasing is the second pulling out and releasing, and the pulled out second wire harness 320 is rewound on the turntable; the third pulling out and releasing is the initial pulling out and releasing, and the second wire harness 320 remains pulled out; the fourth pulling out and releasing is the second pulling out and releasing, and the pulled out second wire harness 320 is rewound on the turntable, and so on. For the data cable of the embodiment of the present application, when the user needs to use the data cable, he only needs to pull out the second wire harness 320 completely wound on the turntable to the required length for the first time and release it, and the second wire harness 320 can remain in the pulled-out state, and the user can conveniently use the pulled-out data cable for charging or data transmission; when the user does not need to use the data cable, he only needs to pull it out and release it again, and the pulled-out second wire harness 320 can be automatically wound on the turntable, return to the initial state of being completely wound on the turntable, and be stored in the housing 100, thereby conveniently realizing the storage of the second wire harness 320, reducing the space occupied by the second wire harness 320, making it not easy to get tangled and easy to carry. The data cable of the embodiment of the present application is not only convenient for the user to use, but also can extend the service life of the data cable and reduce the damage of the data cable.

[0064] See attached Figure 2-8In the embodiment of the present application, the turntable body 210 is provided with an annular wall 211 along the circumferential direction, and a plurality of clamping grooves 212 are evenly provided on the inner side of the annular wall 211 (i.e., the side of the annular wall 211 facing the rotating shaft 111) along the circumferential direction. The limiting assembly includes a clamping member 510, which is rotatably provided on the housing 100 and matches the clamping groove 212. The clamping member 510 is rotatably connected to the bottom shell 110 through a screw 520, and a through hole 511 is provided on the clamping member, and the screw 520 passes through the through hole 511 and engages with the screw groove on the bottom shell 110, so that the clamping member 510 is limited to the bottom shell 110, and the clamping member 510 can rotate around the screw 520 to be clamped or disengaged from the clamping groove 212. The clamping member 510 is configured to clamp with the clamping slot 212 when the wiring harness is first drawn out and released, restricting the turntable from rotating in the second direction, and to disengage from the clamping slot 212 when the wiring harness is drawn out and released again, and no longer restricting the turntable from rotating in the second direction. When the turntable rotates in the first direction, the clamping member 510 can be driven to rotate in the first direction, so that the clamping member 510 and the clamping slot 212 in the clamped state are disengaged from each other. Thus, the rotation of the turntable can be controlled by controlling the rotation of the clamping member 510, so that the second wiring harness 320 is kept in the drawn out state or wound on the turntable.

[0065] In the embodiment of the present application, the limit assembly includes a self-locking switch, which is configured to be in an unlocked state when pressed and released for the first time, and in a self-locking state when pressed and released again, wherein the self-locking switch can push the clamping member 510 to clamp with the clamping groove 212 when it is in the unlocked state, and limit the rotation of the turntable in the second direction, so that the second wire harness 320 drawn out remains in the drawn out state; when the clamping member 510 is in the self-locking state, it no longer pushes the clamping member 510 to clamp with the clamping groove 212, and at this time, the coil spring 410 can drive the turntable to rotate in the second direction by its own elastic force, so that the second wire harness 320 drawn out is rewound on the turntable. The clamping member 510 is configured to press the self-locking switch when the wire harness is first drawn out and again drawn out. The clamping member 510 can be configured to rotate in the first direction driven by the turntable when the turntable rotates in the first direction (that is, when the wire harness is first drawn out and again drawn out), contact the self-locking switch and press the self-locking switch.

[0066] Specifically, in the embodiment of the present application, the self-locking switch includes a slide 540, a slider 550, a limit rod 560, a spring 570 and a slide cover 580. The slide 540 is provided on the bottom shell 110 for accommodating the slider 550. The slide 540 is opened on one side of the clamping member 510, and the slider 550 can extend out of the slide 540 through the opening. The slider 550 can switch between an extended position extending out of the slide 540 and a storage position accommodated in the slide 540. When the slider 550 is in the extended position, it can push the clamping member 510 to engage with the clamping groove 212. A one-way slide 551 is provided on the side of the slider 550 facing the upper cover 121, and the one-way slide 551 has a first position A, a second position B, a third position C, and a fourth position D. Among them, there are respectively a first sliding section, a second sliding section, a third sliding section and a fourth sliding section between the first position A and the second position B, between the second position B and the third position C, between the third position C and the fourth position D, and between the fourth position D and the first position A, wherein the first sliding section and the fourth sliding section are V-shaped as a whole, and the opening of the V-shape faces the opening of the slide groove 540 (that is, toward the clamping member 510); the second sliding section and the third sliding section are also V-shaped as a whole, and the opening of the V-shape also faces the opening of the slide groove 540, and the angle between the second sliding section and the third sliding section is smaller than the angle between the first sliding section and the fourth sliding section. The limiting rod 560 is in a right-angle U-shape, and the cross section of the limiting rod 560 along its extension direction is circular. The first end of the limiting rod 560 is inserted into the insertion hole at the bottom of the slide groove 540 and is rotatably connected to the bottom shell 110. The insertion hole is located on the side of the slider 550 away from the clamping member 510. The second end of the limiting rod 560 is inserted into the one-way slide 551 and can slide along the one-way slide 551 to switch between the first position A, the second position B, the third position C, the fourth position D and the first position A in the slide 551 in sequence. The width of the slide 551 is slightly larger than the diameter of the second end of the limiting rod 560. Steps can be provided at the first position A, the second position B, the third position C, and the fourth position D to prevent the second end of the limiting rod 560 from moving in the opposite direction. The spring 570 is located in the slide groove 540, one end of the spring 570 abuts against the end of the slide groove 540 away from the opening, and the other end abuts against the slider 550, so as to push the slider 550 to move to the extended position. The spring 570 can also be replaced by an elastic member such as a metal spring that can push the slider 550 to move to the extended position. The slide groove cover plate 250 can be connected to the side of the slide groove 540 away from the bottom shell 110 by gluing, so that the slider 550, the limit rod 560 and the spring 570 are kept between the slide groove cover plate 580 and the bottom shell 110, and the limit rod 560 does not separate from the slideway 551.When the second end of the limit rod 560 is in the first position A, the limit rod 560 is engaged with the slide 551 (that is, it is abutted against the intersection of the V-shaped first sliding section and the fourth sliding section), so that the slider 550 is maintained in the storage position; when the second end of the limit rod 560 is in the second position B and the fourth position D, the slider 550 is in the storage position; when the second end of the limit rod 560 is in the third position C, the spring 570 pushes the slider 550 to keep it in the extended position, and the opening of the slide groove 540 can contact the stop portion set at the edge of the slider 550 to limit it from further leaving the slide groove 540.

[0067] See attached Figure 4 In the embodiment of the present application, the clamping member 510 includes a first clamping portion 512, a second clamping portion 513 and a contact portion 514 arranged along the circumferential direction. The first clamping portion 512, the second clamping portion 513 and the contact portion 514 are all protruding portions on the clamping member 510. The first clamping portion 512 and the second clamping portion 513 are respectively used to clamp with the clamping groove 212 and the slider 550, and the contact portion 514 is used to contact the slider 550.

[0068] See attached Figure 6-9 The working principle of the limit assembly in this application is explained.

[0069] See attached Figure 6 When the second wire harness 320 is completely wound on the turntable and has not been pulled out, the second end of the limiting rod 560 is in the first position A, and the second end of the limiting rod 560 is engaged with the slide 551, limiting the movement of the slider 550 out of the slide groove 540, so that the slider 550 remains in the storage position.

[0070] See attached Figure 7 When the second wire harness 320 is initially drawn out, the annular wall 211 is moved in the first direction (ie Figure 6-9 The first clamping portion 512 pushes the clamping member 510 to rotate in the first direction, so that the contact portion 514 presses the slider 550 into the slide groove 540, and the slider 550 moves into the slide groove 540. During this process, the second end of the limiting rod 560 moves from the first position A to the second position B. In the embodiment of the present application, a guiding slope is provided on one side of the slider 550 facing the clamping member 510, and the guiding slope is used to contact the contact portion 514 so that it can better push the slider 550 to move into the slide groove 540.

[0071] See attached Figure 8 When the second wire harness 320 is initially released, the coil spring 410 drives the turntable along the second direction (i.e. Figure 6-9The spring 570 pushes the slider 550 to move out of the slide slot 540, and the second end of the limit rod 560 moves from the second position B to the third position C, and the slider 550 is in an extended state. During the movement, the slider 550 pushes the clamping member 510 to rotate along the second direction through the contact portion 514, so that the first clamping portion 512 is clamped with the clamping slot 212, and the second clamping portion 513 is clamped with the slider 550. After the first clamping portion 512 is clamped with the clamping groove 212, the turntable is restricted from rotating in the second direction; after the second clamping portion 513 is clamped with the slider 550, the slider 550 restricts the second clamping portion 513 from rotating in the second direction, so that the first clamping portion 512 will not rotate in the second direction driven by the coil spring 410 and the turntable after being clamped with the clamping groove 212. Furthermore, the first clamping portion 512 can continue to be clamped with the clamping groove 212, continuously restricting the turntable from rotating in the second direction, so that the pulled out second wiring harness 320 remains in the pulled out state. In the embodiment of the present application, the limit assembly further includes a torsion spring 530, which is sleeved on the clamping member 510, with one end of the torsion spring abutting against the bottom shell 110 and the other end abutting against the clamping member 510. The torsion spring 530 is used to make the clamping member 510 tend to maintain the position when the first clamping portion 512 is clamped with the clamping groove 212 through its own elastic force, so that the slider 550 can better push the clamping member 510 to clamp with the clamping groove 212 when it is in the extended position. It should be noted that when the slider 550 is in the storage position, no matter whether the turntable assembly rotates in the first direction or the second direction, the torsion spring 530 will not limit its rotation.

[0072] See attached Fig. 9 When the second wiring harness 320 is pulled out again, the annular wall 211 rotates along the first direction, and the annular wall 211 pushes the clamping member 510 to rotate along the first direction through the first clamping portion 512, so that the contact portion 514 presses the slider 550 into the slide groove 540, so that the slider 550 moves into the slide groove 540. During this process, the second end of the limiting rod 560 moves from the third position C to the fourth position D.

[0073] See attached Figure 6When the second wire harness 320 is released again, the spring 570 pushes the slider 550 to move out of the slide slot 540, and the second end of the limit rod 560 moves from the fourth position D to the first position A. The second end of the limit rod 560 is engaged with the slideway 551, limiting the slider 550 from moving out of the slide slot 540, so that the slider 550 remains in the storage position, and the slider 550 no longer restricts the rotation of the clamping member 510. At this time, the coil spring 410 can drive the turntable to rotate in the second direction by its own elastic force, and the clamping member 510 can rotate in the second direction under the action of the torsion spring 530 and the turntable, and separate from the slider 550, and the clamping member 510 no longer restricts the rotation of the turntable. The drawn second wire harness 320 can be automatically wound on the turntable under the action of the coil spring 410, stored in the housing 100, and return to the initial state of being completely wound on the turntable, ready for the next withdrawal.

[0074] In some other embodiments, the self-locking switch composed of the slide groove 540, the slider 550, etc. can be replaced with a self-locking switch of other structural forms, such as a self-locking switch corresponding to a button in a ballpoint pen that pops out after being pressed and released for the first time (i.e., is in an unlocked state), and remains in the pressed state (i.e., is in a self-locking state) after being pressed and released again.

[0075] In some other embodiments, the first connecting plate 122 and the second connecting plate 220 may not be provided in the shell 100. Accordingly, the connecting line 300 may include a whole wire harness and two connecting connectors located at both ends of the wire harness, and the two connecting connectors are both located outside the shell 100. The connecting line 300 is wound on the turntable body 210 and is fixedly connected to the turntable body 210, so that when one connecting connector is pulled, the turntable body 210 is driven to rotate, and the other connecting connector will not drive the turntable body 210 to rotate when pulled.

[0076] In some other embodiments, the first wiring harness 310 may not be connected to the first connection connector 330 , but may be configured to be directly connected to a power supply device, such as a battery or a charging control chip in a power bank.

[0077] The present application also provides an electronic device, which includes a data cable as described above. The electronic device may be, for example, a power bank or other power supply device, wherein the first connection connector 330 of the data cable may be used to be detachably connected to a charging interface on the electronic device, and the second connection connector 330 of the data cable may be used to be connected to a device to be charged. In some embodiments, the first wiring harness 310 of the data cable may not be connected to the first connection connector 330, but may be directly connected to a battery or a charging control chip in the electronic device, for example, by welding or other means.
