[0002] Electronic devices refer to devices or apparatuses that use electronic technology to achieve specific functions. Their core characteristic is that they process and manipulate electrical signals through electronic circuits (such as integrated circuits, semiconductor components, etc.). Common electronic devices include chargers, smartphones, televisions, stereos, headphones, etc.

[0003] Currently, some existing electronic devices are quite large, take up a lot of space, and are not easy to store. Therefore, how to reduce the size of electronic devices is one of the topics that the industry needs to study. Summary of the Invention

[0004] This invention provides an ultra-thin telescopic cable module and electronic device to solve the technical problem of how to reduce the size of electronic devices.

[0005] A first aspect of this application provides an ultra-thin telescopic cable module, comprising: a data cable; a spool on which the data cable is wound, the spool being rotatable about its own central axis in two opposite clockwise directions to wind or unwind the data cable; and an electrical adapter plate connected to one end of the spool along its axial direction, the electrical adapter plate extending radially beyond the spool, the side of the electrical adapter plate opposite to the spool having a plurality of conductive annular grooves spaced apart, the plurality of conductive annular grooves being used for electrical contact with other modules rotatable relative to the electrical adapter plate.

[0006] In some embodiments, the electrical adapter board has an electrical connection point on the side opposite to the conductive annular groove, and the electrical connection point is electrically connected to one end of the data cable.

[0007] In some embodiments, a receiving groove is formed on the surface of the rotating wheel facing the electrical adapter plate, and one end of the data cable passes through the receiving groove from the outer periphery of the rotating wheel and is electrically connected to the electrical connection position.

[0008] In some embodiments, when projected along the axial direction of the wheel, the orthographic projection of the electrical connection position falls entirely within the orthographic projection range of the receiving groove.

[0009] In some embodiments, the receiving slot contains a resilient reset member capable of driving the roller to wind up the data cable.

[0010] In some embodiments, the resilient reset member is made of metal, and an insulating partition is blocked on the side of the resilient reset member facing the electrical adapter plate.

[0011] In some embodiments, the insulating partition is housed within the receiving groove.

[0012] In some embodiments, a limiting plate is further included, the limiting plate being connected to one end of the rotating wheel away from the electrical adapter plate, the limiting plate extending radially beyond the rotating wheel, and a winding groove being formed between the portion of the limiting plate and the portion of the electrical adapter plate extending radially beyond the rotating wheel and the outer peripheral surface of the rotating wheel, the portion of the data cable wound around the rotating wheel being accommodated in the winding groove.

[0013] In some embodiments, the limiting plate and the rotating wheel are integrally formed, and / or, one of the rotating wheel and the electrical adapter plate has a insertion groove, and the other has an insertion protrusion, the insertion protrusion being inserted into the insertion groove and thermally fused together.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0035] The specific technical features described in the specific embodiments can be combined in any suitable manner without contradiction. For example, different combinations of specific technical features can form different embodiments and technical solutions. To avoid unnecessary repetition, the various possible combinations of the specific technical features in this utility model will not be described separately.

[0036] In the following description, the terms "first," "second," etc., are used merely to distinguish different objects and do not indicate that the objects have the sameness or relationship. It should be understood that the directional descriptions "above," "below," "outside," and "inside" refer to the orientation under normal use conditions, while "left" and "right" refer to the left and right directions shown in the corresponding diagrams, which may or may not be the left and right directions under normal use conditions.

[0037] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. The term "connection," unless otherwise specified, includes both direct and indirect connections.

[0038] Electronic devices refer to devices or apparatuses that utilize electronic technology to achieve specific functions. Their core characteristic is the processing and manipulation of electrical signals through electronic circuits (such as integrated circuits and semiconductor components). Common electronic devices include chargers, smartphones, televisions, stereos, and headphones. With the continuous development of electronic devices, ongoing research is needed not only in their functionality but also in their miniaturization.

[0039] Some electronic devices include a retractable cable module for retractable data cables. The size of the retractable cable module affects the overall size of the electronic device. This application aims to reduce the size of the electronic device by reducing the size of the retractable cable module. To this end, this application provides an ultra-thin retractable cable module. The ultra-thin retractable cable module is relatively thin, which reduces the space occupied, thereby helping to reduce the size of the electronic device including the ultra-thin retractable cable module.

[0040] The ultra-thin telescopic cable module of this application embodiment can be applied to any electronic device that needs to use an ultra-thin telescopic cable module, such as charging cables, chargers, etc.

[0041] The following describes some embodiments of this application in detail with reference to Figures 1 to 16.

[0042] In some embodiments of this application, for ease of explanation, a first direction, a second direction, and a third direction are defined. These three directions intersect each other; intersecting each other includes perpendicularly intersecting each other. To facilitate understanding of the embodiments of this application, the embodiments shown in Figures 1 to 16 are illustrated using the example of the first direction, second direction, and third direction being perpendicularly intersecting each other. However, those skilled in the art should understand that the embodiments of this application are not limited to the case where these three directions intersect each other perpendicularly. For ease of explanation, as shown by the arrows in Figures 1 to 5 and Figures 8 to 12, the direction where arrow X is located is the first direction, the direction where arrow Y is located is the second direction, and the direction where arrow Z is located is the third direction.

[0043] The first aspect of this application provides an ultra-thin telescopic cable module 6, as shown in Figures 1 to 9. The ultra-thin telescopic cable module 6 includes a data cable 5, a rotating wheel 61, and an electrical adapter plate 62. The data cable 5 is wound around the rotating wheel 61, which is capable of rotating around its central axis in two opposite clockwise directions to wind or unwind the data cable 5. The electrical adapter plate 62 is connected to one end of the rotating wheel 61 along the axial direction of the rotating wheel 61, and extends beyond the rotating wheel 61 radially. The side of the electrical adapter plate 62 facing away from the rotating wheel 61 is provided with a plurality of conductive annular grooves 621 at intervals. The plurality of conductive annular grooves 621 are used for electrical contact with other modules that can rotate relative to the electrical adapter plate 62.

[0044] For example, other modules that are electrically in contact with the plurality of conductive annular grooves 621 may be conductive plates 4, and the electrical contact points 430 of the plurality of terminals 43 of conductive plates 4 are electrically in contact with the plurality of conductive annular grooves 621 of electrical adapter plates 62.

[0045] It should be noted that the data cable 5 is wound around the outer circumference of the reel 61. The end of the data cable 5 closest to the center of the reel 61 is called the connecting end 51, and the end furthest from the center of the reel 61 is the movable end. This means that the movable end extends or shortens as the reel 61 unwinds or rewinds the data cable 5.

[0046] The rotation of the rotating wheel 61 allows for the winding or unwinding of the movable end of the data cable 5. Winding facilitates storage of the electronic device 100, while unwinding allows the charging connector 53 of the data cable 5 to be pulled to a more distant location, improving operational convenience. Furthermore, the electrical adapter plate 62 is electrically connected to other modules (e.g., the conductive plate 4) via the conductive annular groove 621, enabling its conductive function. The electrical adapter plate 62 is connected to one end of the rotating wheel 61 along its axial direction and extends radially beyond the rotating wheel 61, acting as a baffle to prevent the data cable 5 from dispersing to one side of the rotating wheel 61, thus improving the stability of the data cable 5's extension and retraction. The electrical adapter plate 62 also serves as an electrical connection to other modules, combining electrical connection with its function as a baffle, thereby reducing the number of components, minimizing space occupation, and further facilitating the miniaturization of the electronic device 100. In addition, the conductive annular groove 621 is configured as a groove, so that the part of other modules (e.g., conductive plate 4) that cooperates with the conductive annular groove 621 (e.g., electrical contact point 430 of terminal 43 of conductive plate 4) extends into the conductive annular groove 621. The conductive annular groove 621 plays a limiting role and improves the stability of the electrical connection between the two.

[0047] For example, the connection end 51 of the data cable 5 is electrically connected to the side of the electrical adapter plate 62 where the conductive annular groove 621 is provided, or the connection end 51 of the data cable 5 is electrically connected to the side of the electrical adapter plate 62 away from the conductive annular groove 621.

[0048] In some embodiments of this application, as shown in Figures 6 to 8, an electrical connection position 622 is provided on the side of the electrical adapter plate 62 away from the conductive annular groove 621, and the electrical connection position 622 is electrically connected to one end of the data line 5.

[0049] It is understandable that the electrical connection point 622 is electrically connected to the connection end 51 of the data cable 5.

[0050] For example, the electrical connection 622 is soldered to the connection end 51 of the data line 5.

[0051] This design reduces the likelihood of the data cable 5's connection end 51 contacting the conductive annular groove 621, thereby reducing the risk of a short circuit. Furthermore, by placing the electrical connection point 622 on the side facing the rotating wheel 61, the need for the data cable 5 to extend to the electrical adapter plate 62 away from the rotating wheel 61 is avoided, thus shortening the length of the data cable 5. It also eliminates the space occupied by the portion of the data cable 5 extending to the electrical adapter plate 62 away from the rotating wheel 61, further facilitating the miniaturization of the electronic device 100.

[0052] In some embodiments of this application, as shown in Figures 8 and 9, the ultra-thin telescopic cable module 6 further includes a limiting plate 63. The limiting plate 63 is connected to the end of the rotating wheel 61 away from the electrical adapter plate 62. The limiting plate 63 extends beyond the rotating wheel 61 radially. The portion of the limiting plate 63 and the portion of the electrical adapter plate 62 extending radially beyond the rotating wheel 61 forms a winding groove 60 between the limiting plate 63 and the outer peripheral surface of the rotating wheel 61. The portion of the data cable 5 wound around the rotating wheel 61 is accommodated in the winding groove 60.

[0053] With this configuration, the limiting plate 63 acts as a baffle that prevents the data cable 5 from spreading away from the electrical adapter plate 62, thus reliably confining the data cable 5 wrapped around the outer circumference of the rotating wheel 61 within the winding groove 60 and improving the stability of the data cable 5's extension and retraction operation.

[0054] In some embodiments of this application, as shown in Figures 9 and 10, the limiting plate 63 and the rotating wheel 61 are integrally formed, and / or, of the rotating wheel 61 and the electrical adapter plate 62, one has a plug groove 623 and the other has a plug protrusion 612. The plug protrusion 612 is inserted into the plug groove 623 and heat-fused together.

[0055] As exemplarily shown in Figure 10, the limiting plate 63 and the rotating wheel 61 are integrally formed. This improves the reliability of the connection between the two, saves assembly steps, and increases production efficiency.

[0056] As exemplarily shown in Figure 9, one of the rotating wheel 61 and the electrical adapter plate 62 has a insertion groove 623, and the other has an insertion protrusion 612. The insertion protrusion 612 is inserted into the insertion groove 623 and heat-fused together. The rotating wheel 61 and the electrical adapter plate 62 are connected by the insertion protrusion 612 and the insertion groove 623, which improves the reliability of the connection and makes the connection operation convenient.

[0057] In some embodiments of this application, as shown in Figures 9 and 10, a receiving groove 611 is formed on the surface of the rotating wheel 61 facing the electrical adapter plate 62, and one end of the data cable 5 passes through the receiving groove 611 from the outer periphery of the rotating wheel 61 and is electrically connected to the electrical connection position 622.

[0058] In this way, the receiving groove 611 can accommodate a part of the data cable 5, so that the connection end 51 of the data cable 5 is electrically connected to the electrical connection position 622 within the receiving groove 611, avoiding the connection point from being exposed, reducing the risk of the connection point being broken due to contact with other components, and also reducing the occupation of external space, which is conducive to the miniaturization of the ultra-thin telescopic cable module 6, thereby facilitating the miniaturization of the electronic device 100 including the ultra-thin telescopic cable module 6.

[0059] In some embodiments of this application, the orthographic projection of the electrical connection position 622 along the axial projection of the wheel 61 falls entirely within the orthographic projection range of the receiving groove 611.

[0060] This improves the adequacy of the connection between the data cable 5 connector 51 and the electrical connector 622, and also avoids the risk of short circuits caused by the exposed electrical connector 622 making electrical contact with other components.

[0061] In some embodiments of this application, as shown in FIG9, the receiving groove 611 contains a resilient reset member 64 capable of driving the roller 61 to wind up the data cable 5.

[0062] Optionally, the resilient reset element 64 can be made of a metallic or non-metallic material. Non-metallic materials can be, but are not limited to, polyoxymethylene.

[0063] For example, the elastic reset member 64 is connected between the housing and the rotating wheel 61. The elastic reset member 64 can apply an elastic reset force to the rotating wheel 61. The direction of the elastic reset force is opposite to the winding direction of the data cable 5 on the rotating wheel 61. The winding direction refers to the direction from the connection end 51 of the data cable 5 along the direction surrounding the rotating wheel 61 to the moving end.

[0064] Thus, with the elastic reset member 64, when the rotating wheel 61 rotates in the first clockwise direction, the movable end of the data cable 5 extends outward. After the force driving the movable end of the data cable 5 to extend outward is removed, the rotating wheel 61 can rotate in the second clockwise direction, opposite to the first clockwise direction, under the action of the elastic reset member 64, thereby winding the movable end onto the rotating wheel 61. In this way, the elastic reset member 64 enables the rotating wheel 61 to automatically wind up the movable end, eliminating the need for manual rotation of the rotating wheel 61, saving manpower, and improving the user experience. Furthermore, the rotating wheel 61 has a receiving groove 611 for accommodating the elastic reset member 64, saving the space occupied by the elastic reset member 64 within the housing's receiving cavity, and also improving the stability of the elastic reset member 64's installation.

[0065] In some embodiments of this application, the elastic reset member 64 is made of metal, and an insulating partition 65 blocks the side of the elastic reset member 64 facing the electrical adapter plate 62.

[0066] For example, the elastic reset element 64 includes, but is not limited to, a spring or a torsion spring.

[0067] For example, the insulating partition 65 may be made of, but is not limited to, plastic or polyurethane.

[0068] For example, the metal material used for the elastic reset member 64 can be, but is not limited to, carbon spring steel, alloy spring steel, stainless steel, copper alloy, and nickel-based alloy.

[0069] The elastic reset member 64 is made of metal, which improves its durability and extends its service life. Furthermore, an insulating partition 65 is provided on the side of the elastic reset member 64 facing the electrical adapter plate 62, reducing the likelihood of the elastic reset member 64 coming into contact with the electrical connection point 622 and minimizing the chance of the elastic reset member 64 affecting current transmission.

[0070] In some embodiments of this application, as shown in Figures 8 and 9, the insulating partition 65 is accommodated in the receiving groove 611.

[0071] This not only improves the reliability of fixing the insulating partition 65, but also reduces the space occupied by the insulating partition 65 in the accommodating groove 611, further facilitating the miniaturization of the electronic device 100.

[0072] In some embodiments of this application, as shown in Figures 9 and 10, the receiving groove 611 includes a first groove 6111 and a second groove 6112 separated by a partition plate 6110. The partition plate 6110 extends in a circumferential direction around the central axis of the rotating wheel 61. The second groove 6112 surrounds the outer periphery of the first groove 6111. The elastic reset member 64 is accommodated in the first groove 6111. One end of the data cable 5 passes through the second groove 6112 from the outer periphery of the rotating wheel 61.

[0073] For example, the first groove 6111 shares a central axis with the rotating wheel 61.

[0074] For example, the electrical connection position 622 of the electrical adapter plate 62 is opposite to the second groove 6112 in the axial direction of the roller 61.

[0075] In this way, the elastic reset component 64 and the connecting end 51 are separated, which reduces the chance of them interfering with each other and facilitates their stable installation.

[0076] In some embodiments of this application, as shown in Figures 9 and 10, the insulating partition 65 includes a main body 651, which covers the opening of the first groove 6111.

[0077] By sealing the opening of the first groove 6111 by the main body 651, the elastic reset member 64 contained in the first groove 6111 is sealed, which not only facilitates the installation stability of the elastic reset member 64, but also completely blocks the electrical connection position 622 between the elastic reset member 64 and the electrical adapter plate 62, thereby further reducing the probability of the elastic reset member 64 affecting the current transmission.

[0078] In some embodiments of this application, as shown in Figures 9 and 10, the insulating partition 65 further includes an extension 652 extending from the main body 651 to the outer periphery, the extension 652 covering at least a portion of the opening of the second groove 6112.

[0079] By covering at least a portion of the opening of the second groove 6112 with the extension 652, the limiting effect of the connecting end 51 within the second groove 6112 is improved, thereby enhancing the fixing stability of the connecting end 51.

[0080] In some embodiments of this application, as shown in FIG9 and FIG10, the extension 652 is formed with a notch 653, one end of the data line 5 passes through the second groove 6112 and exits through the notch 653, and is electrically connected to a plurality of electrical connection positions 622.

[0081] By setting the notch 653, the connection end 51 of the data cable 5 extends from the second slot 6112 toward the electrical adapter board 62, thereby connecting the connection end 51 to the electrical connection position 622.

[0082] In some embodiments of this application, as shown in Figures 9 and 10, the insulating partition 65 is formed as an integrally molded structure.

[0083] This not only improves the connection strength between the main body 651 and the extension 652, but also saves assembly steps and increases production efficiency.

[0084] In some embodiments of this application, as shown in Figures 9 and 10, a connecting protrusion 6113 extends from one end of the partition plate 6110 facing the electrical adapter plate 62, and a connecting groove 654 is formed in the insulating partition plate 65. The connecting protrusion 6113 is inserted into the connecting groove 654 and heat-fused together.

[0085] By connecting the protrusion 6113 and the connecting groove 654 through insertion and heat fusion, the partition plate 6110 and the insulating partition plate 65 are fixedly connected together. That is, the insulating partition plate 65 is fixedly connected to the rotating wheel 61, which improves the insulation barrier effect of the insulating partition plate 65.

[0086] The second aspect of this application provides an electronic device 100, as shown in FIG2. The electronic device 100 includes a motherboard 2, a conductive plate 4 provided in the first aspect, and an ultra-thin telescopic cable module 6. The electrical connection portion 40 of the conductive plate 4 is electrically connected to the motherboard 2. The ultra-thin telescopic cable module 6 can pull out or retract the data cable 5. Each terminal 43 of the conductive plate 4 is electrically connected to the ultra-thin telescopic cable module 6.

[0087] In some embodiments of this application, as shown in Figures 3 and 8, the motherboard 2 includes a main substrate 21, electronic components 20 electrically connected to the side of the main substrate 21 away from the conductive plate 4, and conductive lines 22 electrically connected to the side of the main substrate 21 facing the conductive plate 4. One end of the conductive lines 22 away from the main substrate 21 is electrically connected to the electrical connection portion 40 of the conductive plate 4.

[0088] For example, the main substrate 21 is a printed circuit board.

[0089] In some embodiments of this application, the thickness direction of the main substrate 21 coincides with the thickness direction of the conductive plate 4, and the two are disposed opposite each other along the thickness direction. This is more conducive to the miniaturization of the electronic device 100.

[0090] In some embodiments of this application, as shown in FIG8, the thickness H4 of the main substrate 21 is in the range of 0.6 mm to 0.8 mm.

[0091] For example, as shown in FIG8, the thickness H4 of the main substrate 21 can be, but is not limited to, 0.6mm, 0.61mm, 0.62mm, 0.63mm, 0.64mm, 0.65mm, 0.66mm, 0.67mm, 0.68mm, 0.69mm, 0.7mm, 0.71mm, 0.72mm, 0.73mm, 0.74mm, 0.75mm, 0.76mm, 0.77mm, 0.78mm, 0.79mm, and 0.8mm.

[0092] Thus, by setting the thickness H4 of the main substrate 21 to be in the range of 0.6mm to 0.8mm, the thickness of the main substrate 21 is relatively small, which reduces the space occupied by the motherboard 2 and further facilitates the miniaturization of the electronic device 100; and the thickness of the main substrate 21 is not too small, so as to meet the size requirements for setting up and arranging circuits.

[0093] In some embodiments of this application, as shown in Figures 6 to 8, the electrical adapter 62 is disposed on the side of the conductive plate 4 facing away from the main board 2, and the distance H3 between the surfaces of the electrical adapter 62 and the conductive substrate 41 of the conductive plate 4 facing each other is in the range of 0.7mm-0.9mm.

[0094] For example, as shown in FIG8, the spacing H3 between the surfaces of the electrical adapter plate 62 and the conductive substrate 41 of the conductive plate 4 that face each other can be, but is not limited to, 0.7mm, 0.71mm, 0.72mm, 0.73mm, 0.74mm, 0.75mm, 0.76mm, 0.77mm, 0.78mm, 0.79mm, 0.8mm, 0.81mm, 0.82mm, 0.83mm, 0.84mm, 0.85mm, 0.86mm, 0.87mm, 0.88mm, 0.89mm, and 0.9mm.

[0095] By limiting the distance H3 between the surfaces of the electrical adapter board 62 and the conductive substrate 41 of the conductive board 4 to face each other to a range of 0.7mm-0.9mm, the space occupied in the first direction X is reduced, and the distance between the two is not too small, thereby meeting the space requirements for arranging components such as the terminal 43.

[0096] In some embodiments of this application, as shown in Figures 1 to 3, the electronic device 100 further includes a connector 3, which is electrically connected to the main substrate 21 and is used for electrical connection to a power source.

[0097] The connector 3 is a mechanical structure used to connect with the power supply. After the connector is plugged in, the two are electrically connected, so that the current in the power supply can be electrically connected to the ultra-thin telescopic cable module 6 through the connector 3, the main board 2, the conductive plate 4 in sequence.

[0098] In some embodiments of this application, as shown in FIG3, the connector 3 includes a pin mounting base 31 and a pin 32 mounted on the pin mounting base 31. The pin mounting base 31 is connected to the housing 1. One end of the pin 32 is electrically connected to the main substrate 21, and the other end is used to connect with a power supply.

[0099] For example, pin 32 is fixedly connected to pin mounting base 31.

[0100] For example, the pin 32 is movably connected to the pin mounting base 31. This movable connection can be either a rotational connection or a sliding connection. The pin 32 can switch between an extended position and a retracted position. When the pin 32 is in the extended position, its extension direction is perpendicular to the outer surface of the pin mounting base 31, allowing it to be inserted into a power socket for charging. When the pin 32 is in the retracted position, it is housed in a receiving groove on the outer surface of the pin mounting base 31, reducing the space occupied by the pin 32 and further reducing the space occupied by the electronic device 100. The movable connection structure between the pin 32 and the pin mounting base 31 can refer to existing technology and will not be described in detail here.

[0101] In some embodiments of this application, as shown in Figures 1 to 3, the electronic device 100 further includes a housing 1, the housing 1 having an internal cavity, the motherboard 2 and the conductive plate 4 being fixed in the cavity, and the ultra-thin telescopic wire module 6 being rotatably mounted on the housing 1 and at least partially housed in the cavity, the motherboard 2, the conductive plate 4 and the ultra-thin telescopic wire module 6 being sequentially distributed along the first direction X.

[0102] In some embodiments of this application, as shown in Figures 1 to 5, the conductive plate 4 includes a conductive substrate 41, a terminal group 44, and an electrical connection portion 40. The terminal group 44 includes a plurality of terminals 43. Each terminal 43 is mounted on one side of the conductive substrate 41. The first end of each terminal 43 is electrically connected to the conductive substrate 41, and there is a gap between the second end of each terminal 43 and the conductive substrate 41. The electrical connection portion 40 is electrically connected to the conductive substrate 41. The thickness H2 of the conductive substrate 41 is in the range of 0.6 mm to 0.8 mm.

[0103] Preferably, the thickness H2 of the conductive substrate 41 is in the range of 0.6 mm to 0.7 mm.

[0104] For example, the conductive substrate 41 is a printed circuit board.

[0105] For example, the thickness H2 of the conductive substrate 41 can be, but is not limited to, 0.6mm, 0.61mm, 0.62mm, 0.63mm, 0.64mm, 0.65mm, 0.66mm, 0.67mm, 0.68mm, 0.69mm, 0.7mm, 0.71mm, 0.72mm, 0.73mm, 0.74mm, 0.75mm, 0.76mm, 0.77mm, 0.78mm, 0.79mm, or 0.8mm.

[0106] The electrical connection part 40 is a component for electrically connecting with a first other module (e.g., motherboard 2). The electrical connection part 40 is electrically connected to the conductive substrate 41, so that the other module electrically connected to the electrical connection part 40 is electrically connected to the conductive substrate 41. Furthermore, the first end of each terminal 43 is electrically connected to the conductive substrate 41, and each terminal 43 is used for electrically connecting with a second other module (e.g., ultra-thin telescopic wire module 6). In this way, the first other module and the second other module can be electrically connected through the conductive plate 4, thereby realizing the conductive function of the conductive plate 4.

[0107] In the embodiments of this application, the electrical connection part 40, the conductive substrate 41, and the terminal 43 are electrically connected in sequence, which can realize the conductive function of the conductive plate 4. Furthermore, the thickness H2 of the conductive substrate 41 is in the range of 0.6mm to 0.8mm, which makes the thickness of the conductive substrate 41 relatively small, which is beneficial to reducing the overall thickness of the conductive plate 4, thereby facilitating the miniaturization of the electronic device 100 including the conductive plate 4. In addition, the thickness of the conductive substrate 41 is not too small to meet the size requirements for setting internal circuits.

[0108] In the embodiments of this application, "multiple" means two or more.

[0109] In some embodiments of this application, as shown in Figures 3 to 5, each terminal 43 includes an electrical contact 430 for electrical connection with other modules, and the distance L between the electrical contact 430 and the conductive substrate 41 is in the range of 0.9 mm to 1.1 mm.

[0110] For example, referring to FIG5, the point of the terminal 43 that is farthest from the conductive substrate 41 is designated as the electrical contact point 430. The distance L between the electrical contact point 430 and the conductive substrate 41 can also be considered as the dimension of the overall structure including the terminal 43 and the terminal mounting portion 42 on which the terminal 43 is mounted in the thickness direction of the conductive substrate 41.

[0111] For example, the distance L between the electrical contact 430 and the conductive substrate 41 can be, but is not limited to, 0.9mm, 0.91mm, 0.92mm, 0.93mm, 0.94mm, 0.95mm, 0.96mm, 0.97mm, 0.98mm, 0.99mm, 1mm, 1.01mm, 1.02mm, 1.03mm, 1.04mm, 1.05mm, 1.06mm, 1.07mm, 1.08mm, 1.09mm, or 1.1mm.

[0112] Thus, by setting the distance L between the electrical contact 430 and the conductive substrate 41 to be in the range of 0.9mm to 1.1mm, the distance between the conductive substrate 41 and other modules is relatively small when the terminal 43 is electrically connected to other modules, which further helps to reduce the space occupied, thereby facilitating the miniaturization of the electronic device 100 including the conductive plate 4; and the distance between the electrical contact 430 and the conductive substrate 41 is not too small, thereby reducing the risk of short circuit.

[0113] In some embodiments of this application, as shown in Figures 3 to 5, the plurality of terminals 43 include a first power terminal 431, a second power terminal 432, a first data terminal 433, a second data terminal 434, and a third data terminal 435; the electrical connection portion 40 includes a first power connection portion 401, a second power connection portion 402, a first data connection portion 403, a second data connection portion 404, and a third data connection portion 405. Part 404 and third data connection part 405 are electrically connected to first power terminal 431, second power terminal 432, first data terminal 433, second data terminal 434 and third data terminal 435 respectively; first data terminal 433, second data terminal 434 and third data terminal 435 are located between first power terminal 431 and second power terminal 432, and the width of first power terminal 431 and second power terminal 432 is greater than the width of first data terminal 433, second data terminal 434 and third data terminal 435.

[0114] Understandably, the first power terminal 431 and the second power terminal 432 are used to transmit current. The first data terminal 433, the second data terminal 434, and the third data terminal 435 are used to transmit digital or analog signals.

[0115] By placing the first data terminal 433, the second data terminal 434, and the third data terminal 435 between the first power terminal 431 and the second power terminal 432, a symmetrical and compact structure is formed, reducing the overall space occupied and facilitating integration on the conductive substrate 41. Furthermore, the widened design of the first power terminal 431 and the second power terminal 432 improves current carrying capacity, reduces resistance and heat generation, and enhances the stability of high-current transmission. Meanwhile, the narrower first data terminal 433, the second data terminal 434, and the third data terminal 435 meet signal transmission requirements and adapt to the low-interference requirements of high-frequency signals.

[0116] In some embodiments of this application, the widths of the first power terminal 431 and the second power terminal 432 are in the range of 0.48 mm to 0.65 mm.

[0117] For example, the width of the first power terminal 431 can be 0.48mm, 0.49mm, 0.50mm, 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, 0.6mm, 0.61mm, 0.62mm, 0.63mm, 0.64mm, or 0.65mm. The width of the second power terminal 432 can be 0.48mm, 0.49mm, 0.50mm, 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, 0.6mm, 0.61mm, 0.62mm, 0.63mm, 0.64mm, or 0.65mm.

[0118] Thus, by setting the width of the first power terminal 431 and the second power terminal 432 to be in the range of 0.48mm to 0.65mm, the current carrying requirements of conventional power transmission can be met, while avoiding the risk of increased resistance and overheating caused by excessive narrowness.

[0119] In some embodiments of this application, the widths of the first data terminal 433, the second data terminal 434, and the third data terminal 435 are in the range of 0.28 mm to 0.45 mm.

[0120] For example, the width of the first data terminal 433 can be, but is not limited to, 0.28mm, 0.29mm, 0.30mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, 0.35mm, 0.36mm, 0.37mm, 0.38mm, 0.39mm, 0.4mm, 0.41mm, 0.42mm, 0.43mm, 0.44mm, or 0.45mm. The width of the second data terminal 434 can be, but is not limited to, 0.28mm, 0.29mm, 0.30mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, 0.35mm, 0.36mm, 0.37mm, 0.38mm, 0.39mm, 0.4mm, 0.41mm, 0.42mm, 0.43mm, 0.44mm, or 0.45mm. The width of the third data terminal 435 can be, but is not limited to, 0.28mm, 0.29mm, 0.30mm, 0.31mm, 0.32mm, 0.33mm, 0.34mm, 0.35mm, 0.36mm, 0.37mm, 0.38mm, 0.39mm, 0.4mm, 0.41mm, 0.42mm, 0.43mm, 0.44mm, and 0.45mm.

[0121] Thus, by setting the width of the first data terminal 433, the second data terminal 434 and the third data terminal 435 to be in the range of 0.28mm to 0.45mm, the width is narrower, which can adapt to the needs of high-frequency signal transmission, reduce parasitic capacitance and crosstalk, improve the impedance matching performance of the data terminal 43, and also reduce the space occupied, which is conducive to the compactness between the terminals 43.

[0122] In some embodiments of this application, as shown in Figures 3 and 4, the electrical connection portion 40 and the terminal group 44 are mounted on the same side of the conductive substrate 41, or the electrical connection portion 40 and the terminal group 44 are mounted on different sides of the conductive substrate 41.

[0123] For example, the electrical connection portion 40 and the terminal group 44 are mounted on the same side of the conductive substrate 41, which reduces the space occupied on the other side of the conductive substrate 41. This is suitable for thickness-sensitive devices (such as ultra-thin consumer electronics products) and reduces the overall structural thickness through centralized wiring on one side. Furthermore, it also reduces the number of flipping steps on the conductive substrate 41 and improves assembly efficiency.

[0124] For example, as shown in Figures 3 and 4, the electrical connection portion 40 and the terminal group 44 are mounted on different sides of the conductive substrate 41, which is suitable for electrical connection between other modules distributed on both sides of the conductive substrate 41, and the dual-sided layout supports the arrangement of more terminals 43.

[0125] In some embodiments of this application, as shown in Figures 4 and 5, the conductive plate 4 further includes a terminal mounting portion 42, which is connected to one side of the conductive substrate 41, and the terminal 43 is mounted on the terminal mounting portion 42.

[0126] By providing the terminal mounting part 42, the terminal 43 is mounted on one side of the conductive substrate 41.

[0127] For example, the terminal mounting portion 42 is made of plastic, which may be, but is not limited to, flame-retardant polycarbonate or polybutylene terephthalate. The plastic body can effectively isolate adjacent terminals 43, prevent short circuits or leakage, and has flame-retardant properties.

[0128] For example, each terminal mounting part 42 is equipped with a plurality of terminals 43, and all terminals 43 mounted on the same terminal mounting part 42 are distributed sequentially at intervals along the width direction of the terminal 43 and are arranged parallel to each other.

[0129] In some embodiments of this application, as shown in FIG4, the terminal mounting portion 42 has five insertion slots arranged sequentially at intervals. The two outermost insertion slots are used to insert the first power terminal 431 and the second power terminal 432, respectively. The three middle insertion slots are used to insert the first data terminal 433, the second data terminal 434, and the third data terminal 435. The insertion slots extend through the first data terminal 43 along a direction intersecting the thickness direction of the conductive substrate 41. The first end and the second end of each terminal 43 extend from the two ends of their corresponding insertion slots. This reduces the possibility of contact between adjacent terminals 43, thereby reducing the probability of mutual interference between the terminals 43.

[0130] In some embodiments of this application, as shown in Figures 4 and 5, the terminal mounting portion 42 is a flat plate structure, and its thickness direction is consistent with the thickness direction of the conductive substrate 41.

[0131] In this way, by setting the terminal mounting part 42 as a flat plate structure, it is beneficial to reduce the space occupied by the terminal mounting part 42 itself. Furthermore, the thickness direction of the terminal mounting part 42 is consistent with the thickness direction of the conductive substrate 41, which can reduce the overall thickness of the structure composed of the terminal mounting part 42 and the conductive substrate 41, further reducing the size of the conductive plate 4, thereby further facilitating the miniaturization of the electronic device 100 including the conductive plate 4.

[0132] In some embodiments of this application, as shown in FIG5, the thickness H1 of the terminal mounting portion 42 is in the range of 0.4mm to 0.6mm.

[0133] For example, the thickness H1 of the terminal mounting portion 42 can be, but is not limited to, 0.4mm, 0.41mm, 0.42mm, 0.43mm, 0.44mm, 0.45mm, 0.46mm, 0.47mm, 0.48mm, 0.49mm, 0.5mm, 0.51mm, 0.52mm, 0.53mm, 0.54mm, 0.55mm, 0.56mm, 0.57mm, 0.58mm, 0.59mm, or 0.6mm.

[0134] Thus, by setting the thickness H1 of the terminal mounting portion 42 to be in the range of 0.4mm to 0.6mm, the thickness H1 of the terminal mounting portion 42 is set to be relatively thin, reducing the space occupied, and also meeting the size requirements of the mounting terminal 43.

[0135] In some embodiments of this application, as shown in FIG4, a plurality of terminal mounting portions 42 are mounted on one side of the conductive substrate 41. Each terminal mounting portion 42 is equipped with a first power terminal 431, a second power terminal 432, a first data terminal 433, a second data terminal 434 and a third data terminal 435.

[0136] This configuration improves the reliability of the electrical connection between the conductive plate 4 and other modules.

[0137] In some embodiments of this application, as shown in Figures 1 to 3, the housing 1 includes a bottom shell 11, a cover 12, and a side panel 13. The bottom shell 11 and the cover 12 are aligned along a first direction X. Both the bottom shell 11 and the cover 12 have notches 14 on the same side along a second direction Y that intersects with the first direction X. The notches 14 are aligned to form an opening. The side panel 13 closes the opening. The bottom shell 11, the cover 12, and the side panel 13 together form a receiving cavity. The movable end 52 of the data cable of the ultra-thin telescopic cable module extends out of the housing 1 through the side panel 13.

[0138] During assembly, the portion of the data cable 5 wound around the rotating wheel 61 can be assembled into the bottom shell 11. The charging connector 53 of the data cable 5 can be passed through the through hole of the side panel 13. Then, the side panel 13 can be installed into the notch 14 of the bottom shell 11. After that, the cover 12 can be assembled into the bottom shell 11 and the side panel 13 along the first direction X, so that the side panel 13 closes the notch 14 of the cover 12, thereby realizing the assembly of the shell 1. In this way, the assembly operation of the electronic device 100 can be simplified, which is conducive to improving the production efficiency of the electronic device 100.

[0139] In some embodiments of this application, as shown in FIG11, the edge of the side panel 13 is formed with an insertion groove 141 and / or an insertion protrusion 131 extending along the direction surrounding the side panel 13, and the edge of the notch 14 is formed with an insertion protrusion 131 and / or an insertion groove 141, and the insertion protrusion 131 and the insertion groove 141 are engaged and inserted.

[0140] For example, the edge of the side panel 13 is formed with an insertion groove 141 extending in the direction surrounding the side panel 13, and the edge of the notch 14 is formed with an insertion protrusion 131, which engages with the insertion groove 141.

[0141] For example, the edge of the side panel 13 is formed with an insertion protrusion 131 extending in the direction surrounding the side panel 13, and the edge of the notch 14 is formed with an insertion groove 141, the insertion protrusion 131 and the insertion groove 141 are engaged and inserted.

[0142] For example, the edge of the side panel 13 is formed with an insertion protrusion 131 and an insertion groove 141 extending in the direction surrounding the side panel 13, and the edge of the notch 14 is formed with an insertion groove 141 and an insertion protrusion 131. The insertion protrusion 131 of the side panel 13 is engaged with the insertion groove 141 of the notch 14, and the insertion groove 141 of the side panel 13 is engaged with the insertion protrusion 131 of the notch 14.

[0143] In this way, the side panel 13 is connected to the bottom shell 11 and the cover 12, and the assembly operation is convenient and the connection is reliable.

[0144] In some embodiments of this application, as shown in FIG11, a protruding rod 111 extends from one end of the bottom shell 11 toward the shell cover 12 along the first direction X, and the shell cover 12 forms a groove (not shown in the figure) that engages with the protruding rod 111.

[0145] For example, the cover 12 is inserted into the groove and heat-fused together.

[0146] For example, the cover 12 is interference-fitted with the groove.

[0147] For example, the cover 12 is fitted with the groove through a gap and bonded to it with an adhesive.

[0148] In this way, the bottom shell 11 and the cover 12 are fixedly connected, the connection operation is convenient, and the connection reliability is high.

[0149] In some embodiments of this application, as shown in FIG12, a mounting post 112 is formed on one of the two shell walls opposite each other along the first direction X of the housing 1. The mounting post 112 passes sequentially through the limiting plate 63, the rotating wheel 61, the insulating partition 65, the electrical adapter plate 62, and the conductive plate 4, and is locked by fasteners 7. The conductive plate 4 is fixedly connected to the housing 1. The limiting plate 63, the rotating wheel 61, the insulating partition 65, and the electrical adapter plate 62 can all rotate around the mounting post 112. The fasteners 7 can be, but are not limited to, bolts, screws, or rivets.

[0150] For example, the mounting post 112 is integrally formed into the bottom shell 11.

[0151] In some embodiments of this application, as shown in FIG12, the connector 3 and the side panel 13 are disposed opposite each other along the second direction Y.

[0152] In some embodiments of this application, as shown in FIG12, the outer contour of the housing 1 has a dimension along the second direction Y that is greater than the dimension along the third direction, and the dimension along the third direction is not less than the dimension along the first direction X.

[0153] In some embodiments of this application, as shown in FIG3, the electronic device 100 further includes a positioning component 8 disposed on the ultra-thin telescopic cable module 6. The positioning component 8 is configured to selectively restrict the rotation of the rotating wheel 61 or release the restriction on the rotating wheel 61, so that the length of the portion of the data cable 5 extending out of the housing 1 is fixed or the length of the portion of the data cable 5 extending out of the housing 1 is adjustable.

[0154] By setting the positioning component 8, the length of the part of the data cable 5 extending out of the housing 1 can be fixed, so as to be suitable for charging devices in different positions and modes, thereby improving charging convenience.

[0155] In some embodiments of this application, as shown in Figures 13 and 15, the positioning component 8 includes a first positioning structure 81 connected to the ultra-thin telescopic wire module 6 and a second positioning structure 82 connected to the housing 1. The first positioning structure 81 shares a central axis with the rotating wheel 61. The first positioning structure 81 has at least one limiting groove 811 formed on its outer peripheral surface around its central axis. One end of the second positioning structure 82 is rotatably connected to the housing 1 around a rotation central axis parallel to the central axis of the rotating wheel 61, and the other end has a limiting protrusion 821. The limiting protrusion 821 is configured to be able to engage with or disengage from the limiting groove 811, thereby limiting the rotation of the rotating wheel 61 or allowing the rotating wheel 61 to rotate.

[0156] Thus, the interaction between the limiting card protrusion 821 and the limiting card groove 811 enables the switching of the rotatable or restricted rotation of the rotating wheel 61, thereby adjusting and fixing the length of the data cable 5 extending out of the housing 1.

[0157] For example, as shown in FIG13, the first positioning structure 81 is disposed on the side of the limiting plate 63 facing away from the rotating wheel 61 and is integrally formed with the limiting plate 63.

[0158] For example, as shown in FIG13, the second positioning structure 82 is formed with a first connecting hole 822, and the bottom shell 11 of the housing 1 is formed with a first connecting shaft (not shown in the figure) that mates with the first connecting hole 822, so that the second positioning structure 82 is rotatably connected to the bottom shell 11 around the first connecting shaft.

[0159] In some embodiments of this application, as shown in Figures 13 to 15, the positioning component 8 further includes a third positioning structure 83. The third positioning structure 83 is configured to limit the second positioning structure 82 to a first rotational position during the outward extension of the data line 5, and to limit the second positioning structure 82 to a second rotational position during the inward retraction of the data line 5. The line connecting the rotation center of the second positioning structure 82 and the center of the rotating wheel 61 is used as a reference line. The first rotational position is located on the positive rotation side of the reference line, and the second rotational position is located on the negative rotation side of the reference line. When the second positioning structure 82 is positioned at the first rotational position by the third positioning structure 83, the limiting protrusion 821 disengages from the limiting groove 811. When the second positioning structure 82 is positioned at the second rotational position by the third positioning structure 83, the limiting protrusion 821 engages with the limiting groove 811.

[0160] As shown in Figure 14, the straight dotted line L represents the reference line, the curved dotted line M represents the forward rotation direction, and the curved dotted line N represents the reverse rotation direction. "The first rotation position is located on the forward rotation side of reference line L, and the second rotation position is located on the reverse rotation side of reference line L" means that the direction of rotation from reference line L to the first rotation position is the forward rotation direction M, and the direction of rotation from reference line L to the second rotation position is the reverse rotation direction N. That is, taking the orientation shown in Figure 14 as an example, the first rotation position is located to the left of reference line L, and the second rotation position is located to the right of reference line L.

[0161] Thus, as the data cable 5 extends outward, the first positioning structure 81 rotates along the reverse rotation direction N with the rotating wheel 61, and the second positioning structure 82 rotates along the forward rotation direction M. When it is positioned at the first rotation position by the third positioning structure 83, the limiting card protrusion 821 disengages from the limiting card groove 811. Then, the second positioning structure 82 allows the first positioning structure 81 to continue rotating along the reverse rotation direction N, thereby allowing the rotating wheel 61 to rotate. As a result, the data cable 5 wrapped around the rotating wheel 61 can continue to extend outward, so that the length of the part of the data cable 5 extending out of the housing 1 continues to increase. When the length of the data cable 5 extending out of the housing 1 reaches a suitable level, the outward extension of the data cable 5 is stopped, and the data cable 5 turns inward to retract. The first positioning structure 81 rotates along the forward rotation direction M with the rotating wheel 61, and the second positioning structure 82 rotates along the reverse rotation direction N. When it rotates to the second rotation position where it is positioned by the third positioning structure 83, the limiting protrusion 821 engages with the limiting groove 811. The second positioning structure 82 then restricts the rotation of the first positioning structure 81, thereby restricting the rotation of the rotating wheel 61 along the forward rotation direction M, so that the data cable 5 no longer continues to retract, thus fixing the length of the data cable 5 extending out of the housing 1 that is wrapped around the rotating wheel 61.

[0162] In some embodiments of this application, as shown in Figures 13 to 15, the third positioning structure 83 is configured to also limit the second positioning structure 82 to a third rotational position during the outward extension of the data line 5, and to limit the second positioning structure 82 to a fourth rotational position during the inward retraction of the data line 5. The third rotational position is located on the positive rotational side of the reference line, and the fourth rotational position is located on the negative rotational side of the reference line. When the second positioning structure 82 is positioned at the third rotational position or the fourth rotational position by the third positioning structure 83, the limiting protrusion 821 disengages from the limiting slot 811.

[0163] Taking the orientation shown in Figure 14 as an example, the third rotation position is located to the left of reference line L, and the fourth rotation position is located to the right of reference line L. It can be understood that because the limiting protrusion 821 of the second positioning structure 82 in the second rotation position engages with the limiting groove 811, while the limiting protrusion 821 of the second positioning structure 82 in the fourth rotation position disengages from the limiting groove 811, the angle between the second rotation position and reference line L is smaller than the angle between the fourth rotation position and reference line L.

[0164] With this configuration, as the data cable 5 extends outward, the first positioning structure 81 rotates along the counter-rotation direction N with the rotating wheel 61, and the second positioning structure 82 rotates along the forward rotation direction M. When it rotates to the third rotation position where it is positioned by the third positioning structure 83, the limiting protrusion 821 disengages from the limiting groove 811. The second positioning structure 82 then allows the first positioning structure 81 to continue rotating along the counter-rotation direction N, thereby allowing the rotating wheel 61 to rotate. Consequently, the data cable 5 wound around the rotating wheel 61 can continue to extend outward, increasing the length of the portion of the data cable 5 extending out of the housing 1. When the outward extension of the data cable 5 stops and it turns inward to retract, the first positioning structure 81 rotates along the forward rotation direction M with the rotating wheel 61, and the second positioning structure 82 rotates along the counter-rotation direction N. During the rotation to the fourth rotation position where it is positioned by the third positioning structure 83, the limiting protrusion 821 remains disengaged from the limiting groove 811, allowing the data cable 5 to retract continuously until it is fully wound back to the bottom. Therefore, after using electronic device 100, the data cable 5 can be quickly rolled up, improving ease of use.

[0165] In some embodiments of this application, as shown in Figures 13 to 15, the second positioning structure 82 has a first locking block 823 and a second locking block 824. The third positioning structure 83 is rotatably connected to the housing 1. The outer periphery of the third positioning structure 83 has a plurality of first locking slots 831 and a plurality of second locking slots 832. The plurality of first locking slots 831 and the plurality of second locking slots 832 are circumferentially distributed around the rotation center axis of the third positioning structure 83 and are alternately arranged. The radial depth of the first locking slot 831 along the third positioning structure 83 is less than the radial depth of the second locking slot 832 along the third positioning structure 83. The shape of the first locking slot 831 is adapted to the shape of the first locking block 823. The shape of the first locking block 823 is adapted to the shape of the second locking block 824. The first locking block 823 can be engaged in the first locking slot 831 or the second locking slot 832, and the second locking block 824 can be engaged in the first locking slot 831 or the second locking slot 832. When the first locking block 823 is engaged in the first locking slot 831, the second positioning structure 82 is limited to the first rotation position. When the second locking block 824 is engaged in the first locking slot 831, the second positioning structure 82 is limited to the second rotation position. When the first locking block 823 is engaged in the second locking slot 832, the second positioning structure 82 is limited to the third rotation position. When the second locking block 824 is engaged in the second locking slot 832, the second positioning structure 82 is limited to the fourth rotation position.

[0166] Thus, during the outward extension of the data cable 5, when the first locking block 823 engages with the first locking groove 831, the second positioning structure 82 is limited to the first rotation position, and the data cable 5 can continue to extend outward. During the process of the data cable 5 stopping its extension and turning inward to retract, the second positioning structure 82 rotates along the reverse rotation direction N until the second locking block 824 engages with the first locking groove 831. Since the groove depth of the first locking groove 831 is shallow and the length of the second locking block 824 is long, the angle that the second positioning structure 82 rotates relative to the reference line L in the reverse rotation direction N is relatively small. The limiting locking protrusion 821 does not disengage from the limiting locking groove 811 and engages with each other, thereby limiting the rotation of the rotating wheel 61 and realizing the limitation of the retraction of the data cable 5. If it is necessary to retract the data cable 5 once, the data cable 5 can be stretched outward again while the second locking block 824 is engaged with the first locking slot 831 (the retraction of the data cable 5 is limited). The first locking block 823 can be engaged with the second locking slot 832. Then, the stretching of the data cable 5 is stopped and it is retracted. The second positioning structure 82 will be limited to the fourth rotation position where the second locking block 824 and the second locking slot 832 are engaged. At this time, the limiting locking protrusion 821 of the second positioning structure 82 and the limiting locking slot 811 of the first positioning structure 81 will disengage from each other, and the data cable 5 will be wound up to the bottom in one go.

[0167] In some embodiments of this application, as shown in Figures 13 to 15, the positioning component 8 further includes an elastic reset structure 84 that applies an elastic reset force to the second positioning structure 82.

[0168] For example, the resilient reset structure 84 is made of, but is not limited to, silicone material.

[0169] Thus, after the second positioning structure 82 rotates relative to the reference line L, the elastic reset structure 84 applies an elastic reset force to the second positioning structure 82, causing the second positioning structure 82 to rotate toward the reference line L, thereby forming a mutual locking force between the second positioning structure 82 and the third positioning structure 83, thereby realizing the length adjustment of the data line 5.

[0170] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
