[0002] This invention relates to the field of electronic components technology, and in particular to a planar slip ring, a rotating conductive component, a telescopic cable module, and a telescopic data cable. [Background Technology]

[0004] The existing planar slip rings have various structures, which leads to uneven force distribution and reduced coaxiality of conductive components during operation and rotation in some cases, thus affecting conductivity and rotational stability. [Summary of the Invention]

[0006] To address the technical problem of poor coaxiality of conductive components in planar slip rings, this invention provides a planar slip ring, a rotating conductive component, a telescopic cable module, and a telescopic data cable.

[0007] The present invention provides a rotating conductive component, comprising a planar slip ring for ensuring a stable electrical connection with a PCB board during rotation, and a first circuit board adapted to the planar slip ring. The planar slip ring includes a structural support and a plurality of conductive elements disposed on the structural support. The structural support includes a limiting ring and an extension segment extending radially away from the center of the limiting ring. The extension segment is integrally formed with the limiting ring and is symmetrically arranged along the limiting ring. The conductive elements are disposed on the extension segments and include contact portions for electrical contact with other external components. Contact points are formed on the contact portion, and the contact points of each conductive element are coplanar and located on the same straight line. The contact portion is arc-shaped, and the contact points are located at the apex of the arc surface of the contact portion. Multiple receiving grooves for accommodating the conductive elements are formed on the extension section. A connecting groove is formed on the structural support, which connects the receiving grooves with the outside of the structural support. The connecting groove is located on the opposite side of the pin extension direction on the structural support. A sliding groove corresponding to the contact portion of the conductive element is formed on the first circuit board. The sliding groove is an arc-shaped sliding groove, and the curvature of the sliding groove is consistent with the curvature of the rotation trajectory of the contact portion of the conductive element.

[0008] Preferably, the extension segment is at least two segments, the extension segments are arranged in an array along the outer edge of the limiting ring, and the conductive elements are evenly spaced on the same side of the extension segments.

[0009] Preferably, the conductive element is embedded in the receiving groove and partially protrudes from the receiving groove.

[0010] Preferably, the conductive component is bent to form a contact portion, the contact portion is arc-shaped, the arc bends away from the extension segment, and an abutment structure is provided on the arc surface of each contact portion, the abutment structure forming the contact point at the position where the arc surface makes electrical contact with other external components.

[0011] Preferably, each of the receiving grooves has a pin on the side away from the conductive element. One end of the pin is electrically connected to the conductive element, and the other end protrudes outward relative to the receiving groove. The pin is integrally formed or spliced ​​with the conductive element.

[0012] Preferably, the limiting ring has an annular protrusion on the side away from the conductive element that forms a contact portion, which is concentric with the limiting ring. The outer diameter of the annular protrusion is smaller than the outer diameter of the limiting ring. The side of the limiting ring closest to the conductive element protrudes from the structural support, and the protrusion height is less than the height of the apex of the contact portion of the conductive element.

[0013] Preferably, the first circuit board is provided with a limiting protrusion adapted to the limiting ring, and the planar slip ring can rotate by the cooperation between the limiting ring and the limiting protrusion.

[0014] Preferably, the first circuit board has a groove corresponding to the contact portion of the conductive element. The groove is formed along the rotation trajectory of the corresponding conductive element, and the conductive element abuts against and is electrically connected to the bottom of the groove.

[0015] Another solution to the technical problem of the present invention is to provide a telescopic component, including the rotating conductive component as described above. The telescopic wire module also includes a data line electrically connected to the rotating conductive component. When the data line is stretched, it will drive the planar slip ring in the rotating conductive component to rotate.

[0016] Another solution to the technical problem of the present invention is to provide a retractable data cable, including a housing and a retractable cable module as described above disposed within the housing.

[0017] Compared with the prior art, the planar slip ring, rotating conductive component, telescopic cable module, and telescopic data cable provided by the present invention have the following beneficial effects:

[0018] 1. This invention provides a planar slip ring for ensuring a stable electrical connection with a PCB board during rotation. The planar slip ring includes a structural support and multiple conductive components mounted on the structural support. The structural support includes a limiting ring and an extension segment extending radially away from the center of the limiting ring. The conductive components are mounted on the extension segment and include contact portions for electrical contact with other external components. Contact points are formed on the contact portions, and the contact points of each conductive component are coplanar and located on the same straight line. Through this design, the limiting ring can limit the position of the planar slip ring and allow it to rotate around the limiting ring. The symmetrically arranged extension segments maintain balanced force at both ends during rotation, thereby reducing wear when the planar slip ring interacts with other components and improving its service life. The contact portions of the conductive components facilitate contact with other components, and the contact points of the contact portions being on the same straight line ensure overall coaxiality, making the rotation of the planar slip ring more stable.

[0019] 2. The present invention provides a planar slip ring, wherein the extension segment has at least two segments, which are arranged in an array along the outer edge of the limiting ring, and conductive elements are evenly spaced on the same side of the extension segments. With this design, the conductive elements are arranged in an array on the extension segments. During operation, the conductive elements on the extension segments will resist and slide relative to other components, experiencing the same frictional force, thereby ensuring the balance and stability of the planar slip ring's rotation and enhancing its working stability.

[0020] 3. The present invention provides a planar slip ring with multiple receiving grooves on its extension section for accommodating conductive components. The conductive components are embedded in the receiving grooves and partially protrude from them. This design allows the conductive components to be easily replaced when they have been used for a long time or are excessively worn, and also simplifies the structure and makes manufacturing more convenient.

[0021] 4. The present invention provides a planar slip ring in which the conductive component is bent to form a contact portion. The contact portion is arc-shaped, with the arc bending away from the extending section. Each contact portion has an abutment structure on its arc surface, forming a contact point at the location where the arc surface makes electrical contact with other external components. This design facilitates contact between the conductive component and other components. The arc shape of the contact portion reduces the contact area and makes the contact surface smoother, ensuring smooth sliding of the conductive component and thus making the rotation of the planar slip ring more stable. The abutment structure acts as an intermediate layer connecting the conductive component and abutting other components, enhancing contact, reducing impedance, and ensuring better conductivity.

[0022] 5. The present invention provides a planar slip ring, wherein each receiving groove has a pin on the side away from the conductive element. One end of the pin is electrically connected to the conductive element, and the other end protrudes outward relative to the receiving groove. The pin and the conductive element are integrally formed or spliced ​​together. With this design, the pin and the conductive element form a simple circuit loop. The pin is used to electrically connect to the data line to obtain electrical signals and transmit the electrical signals through the conductive element, or to receive electrical signals transmitted by components or devices electrically connected to the conductive element and transmit them to the data line.

[0023] 6. The present invention provides a planar slip ring, wherein an annular protrusion concentrically arranged with the limiting ring is provided on the side of the limiting ring away from the contact portion formed by the conductive component. This design allows the annular protrusion to engage with other components, further ensuring the stability of the connection; the outer diameter of the annular protrusion is smaller than the outer diameter of the limiting ring. This simplifies the overall structure, allows the annular protrusion to engage with other components for further limiting, and increases the stability of the connection.

[0024] 7. The present invention provides a rotating conductive component, comprising the aforementioned planar slip ring and a first circuit board adapted to the planar slip ring. The first circuit board is provided with a limiting protrusion adapted to a limiting ring. The planar slip ring can rotate by the cooperation of the limiting ring and the limiting protrusion. The rotating conductive component has the same beneficial effects as the aforementioned planar slip ring, which will not be elaborated here.

[0025] 8. The present invention provides a rotating conductive component, wherein a groove corresponding to the contact portion of a conductive element is formed on a first circuit board. The groove is formed along the rotation trajectory of the corresponding conductive element, and the conductive element abuts against and is electrically connected to the bottom of the groove. With this design, when the planar sliding plate rotates, the conductive element can move within the groove, maintaining electrical connection with the bottom of the groove at all times, facilitating the transmission of electrical signals.

[0026] 9. The present invention provides a telescopic cable module, comprising the rotary conductive component as described above, and the telescopic cable module further comprising a data cable electrically connected to the rotary conductive component, characterized in that: when the data cable is stretched, it causes the planar slip ring in the rotary conductive component to rotate. It has the same beneficial effects as the rotary conductive component described above, and will not be elaborated further here.

[0027] 10. The present invention provides a retractable data cable, comprising a housing and a retractable cable module as described above disposed within the housing. It has the same beneficial effects as the retractable cable module described above, and will not be elaborated further here. [Attached Image Description]

Detailed Implementation Methods

[0043] To make the objectives, technical solutions, and advantages of this invention clearer, the invention 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 and not intended to limit the invention.

[0044] Please combine Figure 1 and Figure 2 The first embodiment of the present invention provides a planar slip ring 1 for ensuring a stable electrical connection with a PCB board during rotation. The planar slip ring 1 includes a structural support 11 and a plurality of conductive elements 12 disposed on the structural support 11. The structural support 11 includes a limiting ring 111 and an extension segment 112 extending radially away from the center of the limiting ring 111. The conductive elements 12 are disposed on the extension segment 112 and include a contact portion 121 for electrical contact with other external components. Contact points 1211 are formed on the contact portion 121. The contact points 1211 of each conductive element are coplanar and located on the same straight line.

[0045] It should be noted that the shape of the limiting ring 111 is not limited and does not necessarily have to be circular. To facilitate rotation, the inner wall of the limiting ring 111 is usually circular, which can abut against the fixed position of the sliding ring 1 of the mating structure and can rotate while the inner wall of the limiting ring 111 is in contact with it.

[0046] Specifically, in a specific embodiment of the present invention, the limiting ring 111 adopts a circular design with a certain thickness between the inner and outer walls to ensure the mechanical properties of the limiting ring 111. The extension section 112 is integrally formed with the limiting ring 111 and extends to the opposite sides.

[0047] Understandably, through this design, the limiting ring 111 can limit the position of the planar slip ring 1 and can rotate around the limiting ring 111. The symmetrically arranged extension section 112 can keep the force at both ends balanced during rotation, thereby reducing the wear of the planar slip ring 1 when it interacts with other components and improving its service life. The contact part 121 of the conductive part 12 can easily abut against other components. The contact points of the contact part 121 are on the same straight line to ensure the coaxiality of the whole, making the rotation process of the planar slip ring 1 more stable.

[0048] Furthermore, the extension segment 112 has at least two segments, and the extension segment 112 is arranged in an array along the outer edge of the limiting ring 111, with the conductive elements 12 evenly spaced on the same side of the extension segment 112.

[0049] It should be noted that "same side" here refers to the same side along the axial direction of the limiting ring 111, rather than the same side along the radial direction of the extension 112. That is, the conductive element 12 is preferably coplanar on the same side of the extension 112. Then, in the case of coplanarity, the coaxiality is ensured by limiting the position of the conductive element 12 and adjusting the contact point 1211.

[0050] Optionally, the two sides are axially symmetric or centrally symmetric.

[0051] Understandably, in order to ensure the coaxiality of the conductive component 12 set on it and the overall balanced force of the planar slip ring 1, the extension segment 112 is arranged in an array. Therefore, there is no limit to the total number of extension segments 112, and it can be an even number. The number of extension segments 112 can also be an odd number, such as three or five, to satisfy the central symmetry so that the planar slip ring 1 is subjected to balanced force.

[0052] It should be noted that although increasing the number of extension sections 112 can enhance the working stability of the planar slip ring 1, it will also increase the cost. Therefore, choosing two or three extension sections 112 is a better solution.

[0053] Specifically, in this embodiment of the invention, there are two extension segments 112, and the conductive element 12 is disposed on the same side of the extension segment 112 and is on the same straight line.

[0054] Understandably, through this design, the conductive elements 12 are symmetrically and spaced apart on the extension section 112, and the extension section 112 is axially and centrally symmetrically arranged on both sides of the limiting ring 111. During operation, the conductive elements 12 on the extension section 112 will resist and slide relative to other components, and the frictional force they experience is the same, thereby ensuring the balance and stability of the rotation of the planar slip ring 1.

[0055] Furthermore, the conductive component 12 is bent to form a contact portion 121. The contact portion 121 is arc-shaped, and the arc bends away from the extension section 112. Each contact portion 121 has an abutment structure 122 on its arc surface. The abutment structure 122 forms a contact point 1221 at the position where the arc surface makes electrical contact with other external components.

[0056] It should be noted that the conductive component 12 itself is made of metal and can conduct electricity. The contact structure 122 is set to improve the conductivity.

[0057] Understandably, through this design, the contact portion 121 of the conductive element 12 can easily abut against other components. The arc shape of the contact portion 121 can reduce the contact area to a certain extent, and the contact surface is smoother, ensuring the smoothness of the conductive element 12 during the sliding process, thereby making the rotation process of the planar slip ring 1 more stable. The abutment structure 122 can serve as an intermediate layer to connect the conductive element 12 and abut against other components, which can enhance contact, reduce impedance, and ensure better conductivity.

[0058] Specifically, in a specific embodiment of the present invention, the conductive element 12 is a metal spring sheet. In addition, in order to ensure that the conductive elements 12 are on the same straight line, the arc of the contact portion 121 needs to be controlled to be of the same specification and the center of the arc is on the same straight line, so that the contact point 1221 of each conductive element 12 is at the same height. Specifically, the arc specification is not limited here, but is subject to actual needs.

[0059] It should be noted that the number of conductive elements 12 is not limited here and can be designed according to actual needs, and the length of the extension section 112 can be adjusted synchronously as needed.

[0060] Furthermore, please combine Figure 2 and Figure 3 The extension section 112 has multiple receiving grooves 1121 for accommodating the conductive element 12. The conductive element 12 is embedded in the receiving grooves 1121 and partially protrudes from the receiving grooves 1121.

[0061] It should be noted that the receiving groove 1121 is spaced apart on the extension section 112 along with the conductive element 12, and the width of the receiving groove 1121 corresponds to the width of the conductive element 12.

[0062] Understandably, with this design, the conductive component 12 is embedded in the receiving groove 1121, which makes the structure simpler and the manufacturing process more convenient.

[0063] In addition, one end of the conductive element 12 is embedded in the receiving groove 1121, and the other end is suspended along with the contact portion 121. In a specific embodiment of the present invention, the suspended end of the conductive element 12 is housed in the receiving groove 1121 to protect the conductive element 12 and reduce the space occupancy rate of the conductive element 12.

[0064] Understandably, the arc-shaped opening in the conductive component 12 can effectively and automatically adjust the contact position and the magnitude of the contact pressure when the conductive component 12 comes into contact with other components.

[0065] Furthermore, each receiving groove 1121 has a pin 13 on the side away from the conductive element 12. One end of the pin 13 is electrically connected to the conductive element 12, and the other end protrudes outward relative to the receiving groove 1121. The pin 13 is integrally formed or spliced ​​with the conductive element 12.

[0066] It should be noted that pin 13 and conductive element 12 are connected at one end embedded in the receiving groove 1121 and are embedded together in the receiving groove 1121. The other end of pin 13 extends out of the receiving groove 1121 to connect to the data line. On the one hand, this ensures the electrical connection between pin 13 and conductive element 12 to realize the transmission of electrical signals. On the other hand, it ensures the stable fixation of conductive element 12 and pin 13, preventing pin 13 and / or conductive element 12 from falling off due to external force or friction during use or rotation, thereby reducing the service life of the flat slip ring 1.

[0067] Understandably, through this design, pin 13 and conductive element 12 form a simple circuit loop. Pin 13 is used to electrically connect to the data line to obtain electrical signals and transmit the electrical signals through conductive element 12, or to receive electrical signals transmitted by components or devices electrically connected to conductive element 12 and transmit them to the data line.

[0068] Specifically, the structural support 11 has a connecting groove 1121 and a connecting groove 1123 on the outside of the structural support. The connecting groove 1123 is located on the opposite side of the extension direction of the pin 13 on the structural support 11. The user can use the connecting groove 1123 to confirm the connection status of the pin 13 and the conductive element 12, as well as the embedded status of the pin 13 and the conductive element 12 in the receiving groove 1121.

[0069] Furthermore, please combine Figure 3 and Figure 4 The limiting ring 111 protrudes from the structural support 11 on the side near the conductive element 12, and the protrusion height is less than the height of the apex of the contact portion 121 of the conductive element 12.

[0070] Understandably, this design increases the stability of the connection between the flat slip ring 1 and other components, and the height limitation prevents the limiting ring 111 from rubbing against other components, thereby affecting the smoothness of the rotation of the flat slip ring 1.

[0071] Furthermore, an annular protrusion 1111 is provided on the side of the limiting ring 111 away from the conductive member 12 where the contact portion 121 is formed. The protrusion 1111 is concentric with the limiting ring 111.

[0072] Furthermore, the sidewalls of the limiting ring 111 and the annular protrusion 1111 near the conductive element 12 are defined as the outer sidewalls, and the sidewalls opposite to the outer sidewalls are defined as the inner sidewalls. The inner sidewalls of the annular protrusion 1111 and the inner sidewalls of the limiting ring 111 are on the same plane. The diameter between the outer sidewalls of the annular protrusion 1111 is smaller than the diameter between the outer sidewalls of the limiting ring 111, that is, the thickness between the inner and outer sidewalls of the annular protrusion 1111 is smaller than the thickness between the inner and outer sidewalls of the limiting ring 111.

[0073] It should be noted that the annular protrusion 1111 is positioned close to the inner wall of the limiting ring 111, so that the inner wall of the annular protrusion 1111 and the inner wall of the limiting ring 111 are on the same plane.

[0074] Understandably, through this design, the inner wall of the annular protrusion 1111 and the inner wall of the limiting ring 111 are on the same plane, making the overall structure simpler. The annular protrusion 1111 can cooperate with other components for further limiting, further ensuring the stability of the connection.

[0075] Furthermore, a partition plate 1122 is also provided on the structural support 11.

[0076] It should be noted that the position of the partition 1122 is not limited, as long as it is symmetrically arranged on the extension section 112. Specifically, in the specific embodiment of the present invention, the partition 1122 is set at the position of one conductive element 12 from the limit ring 111 towards the extension section 112, and is set again at intervals of five conductive elements 12.

[0077] Understandably, the partition 1122 is used to limit the spacing of the conductive element 12 and the position of the limiting ring 111 and the conductive element 12, while adding a certain counterweight to ensure the reliability of the planar slip ring 1 during rotation.

[0078] Please combine Figure 4 and Figure 5 The present invention also provides a rotating conductive component 2 to solve the technical problem described above, including the planar slip ring 1 and a first circuit board 21 adapted to the planar slip ring 1. The first circuit board 21 is provided with a limiting protrusion 211 adapted to the limiting ring 111. The planar slip ring 1 can rotate by the cooperation of the limiting ring 111 and the limiting protrusion 211. The rotating conductive component 2 has the same beneficial effects as the planar slip ring 1 described above, which will not be elaborated here.

[0079] Furthermore, the first circuit board 21 of the rotating conductive assembly 2 is provided with a groove 212 corresponding to the contact portion 121 of the conductive member 12. The groove 212 is opened along the rotation trajectory of the corresponding conductive member 12, and the conductive member 12 abuts against and is electrically connected to the bottom of the groove 212.

[0080] It should be noted that there are usually two first circuit boards 21. The planar slip ring 1 is placed in the two first circuit boards 21 to assist in rotation or reset. The first circuit board 21 on the side closer to the conductive element 12 is as described above, and the first circuit board 21 on the side farther away from the conductive element 12 is designed according to actual needs or the corresponding structure of the planar slip ring 1 to ensure the normal implementation of the function.

[0081] Understandably, with this design, when the flat slide rotates, the conductive component 12 can move within the slide groove 212, maintaining an electrical connection with the bottom of the slide groove 212 at all times, which facilitates the transmission of electrical signals.

[0082] Furthermore, the rotating conductive component 2 also includes a second circuit board 22, on which the planar slip ring 1 is disposed and electrically connected to the second circuit board 22.

[0083] For specific details, please refer to... Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of the circuit board for the second circuit board. Figure 7 This is a schematic diagram of the circuit board for the second circuit board.

[0084] Please see Figure 8 The present invention also provides a retractable cable module 3 to solve the technical problem described above. The retractable cable module 3 includes the rotating conductive component 2 as described above. The retractable cable module 3 further includes a data cable 31 electrically connected to the rotating conductive component 2. Stretching the data cable 31 causes the planar slip ring in the rotating conductive component 2 to rotate. The retractable cable module 3 has the same beneficial effects as the rotating conductive component 2 described above, which will not be elaborated upon here.

[0085] Furthermore, the present invention also provides a retractable data cable to solve the technical problem, including a housing and the aforementioned retractable cable module disposed within the housing.

[0086] In the embodiments provided by this invention, it should be understood that "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0087] It should be understood that the phrase "one embodiment" or "an embodiment" throughout the specification means that a specific feature, structure, or characteristic related to the embodiment is included in at least one embodiment of the invention. Therefore, "in one embodiment" or "in an embodiment" appearing throughout the specification does not necessarily refer to the same embodiment. Furthermore, these specific features, structures, or characteristics can be combined in any suitable manner in one or more embodiments. Those skilled in the art should also recognize that the embodiments described in the specification are optional embodiments, and the actions and modules involved are not necessarily essential to the invention.

[0088] In various embodiments of the present invention, it should be understood that the sequence number of each process does not necessarily imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

In this regard, each block in a flowchart or block diagram may represent a module, segment, or portion of code containing one or more executable instructions for implementing a specified logical function. It should also be noted that in some alternative implementations, the functions indicated in the blocks may occur in a different order than those indicated in the drawings. For example, two consecutively indicated blocks may actually be executed substantially in parallel, and they may sometimes be executed in reverse order, depending on the functions involved. It is particularly important to note that each block in the block diagrams and / or flowcharts, and combinations of blocks in the block diagrams and / or flowcharts, can be implemented using a dedicated hardware-based system that performs the specified function or operation, or using a combination of dedicated hardware and computer instructions.

[0090] Compared with the prior art, the planar slip ring, rotating conductive component, telescopic cable module, and telescopic data cable provided by the present invention have the following beneficial effects:

[0091] 1. This invention provides a planar slip ring for ensuring a stable electrical connection with a PCB board during rotation. The planar slip ring includes a structural support and multiple conductive components mounted on the structural support. The structural support includes a limiting ring and an extension segment extending radially away from the center of the limiting ring. The conductive components are mounted on the extension segment and include contact portions for electrical contact with other external components. Contact points are formed on the contact portions, and the contact points of each conductive component are coplanar and located on the same straight line. Through this design, the limiting ring can limit the position of the planar slip ring and allow it to rotate around the limiting ring. The symmetrically arranged extension segments maintain balanced force at both ends during rotation, thereby reducing wear when the planar slip ring interacts with other components and improving its service life. The contact portions of the conductive components facilitate contact with other components, and the contact points of the contact portions being on the same straight line ensure overall coaxiality, making the rotation of the planar slip ring more stable.

[0092] 2. The present invention provides a planar slip ring, wherein the extension segment has at least two segments, which are arranged in an array along the outer edge of the limiting ring, and conductive elements are evenly spaced on the same side of the extension segments. With this design, the conductive elements are arranged in an array on the extension segments. During operation, the conductive elements on the extension segments will resist and slide relative to other components, experiencing the same frictional force, thereby ensuring the balance and stability of the planar slip ring's rotation and enhancing its working stability.

[0093] 3. The present invention provides a planar slip ring with multiple receiving grooves on its extension section for accommodating conductive components. The conductive components are embedded in the receiving grooves and partially protrude from them. This design allows the conductive components to be easily replaced when they have been used for a long time or are excessively worn, and also simplifies the structure and makes manufacturing more convenient.

[0094] 4. The present invention provides a planar slip ring in which the conductive component is bent to form a contact portion. The contact portion is arc-shaped, with the arc bending away from the extending section. Each contact portion has an abutment structure on its arc surface, forming a contact point at the location where the arc surface makes electrical contact with other external components. This design facilitates contact between the conductive component and other components. The arc shape of the contact portion reduces the contact area and makes the contact surface smoother, ensuring smooth sliding of the conductive component and thus making the rotation of the planar slip ring more stable. The abutment structure acts as an intermediate layer connecting the conductive component and abutting other components, enhancing contact, reducing impedance, and ensuring better conductivity.

[0095] 5. The present invention provides a planar slip ring, wherein each receiving groove has a pin on the side away from the conductive element. One end of the pin is electrically connected to the conductive element, and the other end protrudes outward relative to the receiving groove. The pin and the conductive element are integrally formed or spliced ​​together. With this design, the pin and the conductive element form a simple circuit loop. The pin is used to electrically connect to the data line to obtain electrical signals and transmit the electrical signals through the conductive element, or to receive electrical signals transmitted by components or devices electrically connected to the conductive element and transmit them to the data line.

[0096] 6. The present invention provides a planar slip ring, wherein an annular protrusion concentrically arranged with the limiting ring is provided on the side of the limiting ring away from the contact portion formed by the conductive component. This design allows the annular protrusion to engage with other components, further ensuring the stability of the connection; the outer diameter of the annular protrusion is smaller than the outer diameter of the limiting ring. This simplifies the overall structure, allows the annular protrusion to engage with other components for further limiting, and increases the stability of the connection.

[0097] 7. The present invention provides a rotating conductive component, comprising the aforementioned planar slip ring and a first circuit board adapted to the planar slip ring. The first circuit board is provided with a limiting protrusion adapted to a limiting ring. The planar slip ring can rotate by the cooperation of the limiting ring and the limiting protrusion. The rotating conductive component has the same beneficial effects as the aforementioned planar slip ring, which will not be elaborated here.

[0098] 8. The present invention provides a rotating conductive component, wherein a groove corresponding to the contact portion of a conductive element is formed on a first circuit board. The groove is formed along the rotation trajectory of the corresponding conductive element, and the conductive element abuts against and is electrically connected to the bottom of the groove. With this design, when the planar sliding plate rotates, the conductive element can move within the groove, maintaining electrical connection with the bottom of the groove at all times, facilitating the transmission of electrical signals.

[0099] 9. The present invention provides a telescopic cable module, comprising the rotary conductive component as described above, and the telescopic cable module further comprising a data cable electrically connected to the rotary conductive component, characterized in that: when the data cable is stretched, it causes the planar slip ring in the rotary conductive component to rotate. It has the same beneficial effects as the rotary conductive component described above, and will not be elaborated further here.

[0100] 10. The present invention provides a retractable data cable, comprising a housing and a retractable cable module as described above disposed within the housing. It has the same beneficial effects as the retractable cable module described above, and will not be elaborated further here.
