Advantages of the Invention

[0024] Compared with the prior art, the disk slip ring, the rotary conductive assembly and the pull-in type data cable assembly according to the present invention have the following advantages.

[0025] 1. The disk slip ring according to the present invention ensures a stable electrical connection with the PCB board during rotation. The disk slip ring includes a structural holder and a plurality of conductive members provided on the structural holder. The structural holder includes a limiting ring and an extending stage symmetrically extending along the radial direction of the limiting ring. The conductive member is provided on the extending stage and includes a contact portion that electrically contacts another external assembly. A contact point is formed on the contact portion, and the contact points of each conductive member are coplanar and on the same straight line. According to this design, the limiting ring can limit the position of the disk slip ring and can rotate around the limiting ring. The symmetrically provided extending stage can well maintain the balance of the forces received at both ends during rotation, reduce the wear of the disk slip ring when acting with other assemblies, and extend the service life. The contact portion of the conductive member is convenient for abutting against other assemblies. Since the contact points of the contact portion are on the same straight line, the overall coaxiality can be maintained, thereby making the rotation process of the disk slip ring more stable.

[0026] 2. In the disk slip ring according to the present invention, there are at least two extending stages, which are axially symmetric or centrosymmetric on both sides of the limiting ring. According to this design, the conductive members are symmetrically and spaced apart on the extending stage, and the extending stage is axially symmetric and centrosymmetric on both sides of the limiting ring. During operation, the conductive members on the extending stage press against other assemblies and slide relatively, receiving the same frictional force, thereby ensuring the balance and stability of the rotation of the disk slip ring.

[0027] 3. In the disk slip ring according to the present invention, the conductive members are provided at equal intervals on the same side in the axial direction of the limiting ring of the extending stage. According to this design, when the conductive members on the extending stage rotate, the connection line of the contact points and the rotation center are always on the same straight line, thereby ensuring the balance and stability in the rotation process of the disk slip ring.

[0028] 4. In the disc slip ring according to the present invention, the disc slip ring further includes a plurality of pins electrically connected to a conductive member, and the extension stage has a plurality of accommodating grooves for accommodating the conductive member and the pins. The pins and the conductive member constitute a simple circuit loop, the pins are electrically connected to a data cable to acquire electrical signals, transmit electrical signals by the conductive member, or receive electrical signals transmitted from an assembly or device electrically connected to the conductive member and transmit them to the data cable, the accommodating grooves serve to restrain the conductive member and the pins, preventing the disc slip ring from loosening or falling off due to rotation, thereby reducing its function or requiring disposal.

[0029] 5. In the disc slip ring according to the present invention, the conductive members and pins are fitted into the housing grooves and all partially protrude from the housing grooves. According to this design, the conductive members and pins are fitted into the housing grooves, the housing grooves can secure the conductive members and pins, and they can be easily replaced if they are used for a long period of time or if the elements are excessively worn out. Furthermore, the simple structure makes production and processing easier.

[0030] 6. In the disc slip ring according to the present invention, a portion of the conductive member is bent to form a contact portion, and abutment structures are provided on the bent surfaces of each contact portion. The abutment structures form contact points on the bent surfaces at positions that electrically contact other external assemblies. According to this design, the contact portion of the conductive member is convenient for contact with other assemblies, and the abutment structures are connected to the conductive member as an intermediate layer, allowing them to abut against other assemblies, thereby strengthening contact, reducing resistance, and ensuring better conductivity.

[0031] 7. In the disc slip ring according to the present invention, the contact portion is arc-shaped, the arc is curved in the opposite direction to the extension step, and the abutment structure is provided on the arc-shaped surface of each contact portion. By making the contact portion arc-shaped, the contact area is reduced to some extent, and the contact surface is made smoother, thereby ensuring the smoothness of the process in which the conductive member presses against the contact surface and slides, and thereby making the rotation process of the disc slip ring more stable.

[0032] 8. In the disc slip ring according to the present invention, the limiting ring protrudes from the structural holder on the side closer to the conductive member, and the height of the protrusion is smaller than the height of the apex of the contact portion of the conductive member. By providing the limiting ring to protrude, the contact area between the inner wall of the limiting ring and other structures is increased, the position of the limiting ring is well limited, insufficient coupling and loosening during operation are avoided, and by limiting the protrusion height, friction is prevented from occurring at the interface of the protruding portion against other structures, thereby reducing the smoothness of use, as well as preventing wear and ensuring the service life of the disc slip ring.

[0033] 9. In the disc slip ring according to the present invention, the limiting ring is provided with an annular protrusion on the side where the contact portion is formed, away from the conductive member, which forms a concentric link structure with respect to the limiting ring. According to this design, the annular protrusion can be mated and connected to other assemblies, further enhancing the stability of the connection.

[0034] 10. In the disc slip ring according to the present invention, 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 work in conjunction with other assemblies to provide further positional constraints, and improves connection stability.

[0035] 11. The rotating conductive assembly according to the present invention includes the above-described disc slip ring and a limiting plate that fits the disc slip ring, wherein the limiting plate is provided with limiting protrusions that fit the limiting ring, and the disc slip ring can rotate through the cooperation between the limiting ring and the limiting protrusions. The rotating conductive assembly has the same beneficial effects as the above-described disc slip ring and will not be described in detail here.

[0036] 12. In the rotating conductive assembly according to the present invention, a sliding groove corresponding to the contact portion of the conductive member is provided in the first limiting plate, the sliding groove is provided along the rotational trajectory of the corresponding conductive member, and the conductive member presses against the bottom of the sliding groove and is electrically connected. According to this design, when the planar sliding plate rotates, the conductive member moves within the sliding groove and is always electrically connected to the bottom of the sliding groove, facilitating the transmission of electrical signals.

[0037] 13. The retractable data cable assembly according to the present invention includes the aforementioned rotating conductive assembly, further including a data cable electrically connected to the rotating conductive assembly, characterized in that pulling the data cable rotates the disk slip ring of the rotating conductive assembly. It has the same beneficial effects as the aforementioned rotating conductive assembly and will not be described in detail here. [Brief explanation of the drawing]

The specific meanings of these terms in the present invention can be understood by those skilled in the art depending on the context.

[0044] Furthermore, the terms “attach,” “install,” “provide,” “connect,” and “link” should be understood in a broad sense. For example, they may be fixed connections, detachable connections, or integrated configurations. They may be mechanical connections or electrical connections. They may be direct connections, indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. The specific meanings of the above terms in this invention can be understood by those skilled in the art depending on the context.

[0045] As shown in Figures 1 and 2, a first embodiment of the present invention provides a disk slip ring 1 for ensuring a stable electrical connection with a PCB substrate during rotation, the disk slip ring 1 comprising a structural holder 11 and a plurality of conductive members 12 provided on the structural holder 11, the structural holder 11 comprising a limiting ring 111 and an extension step 112 extending symmetrically along the radial direction of the limiting ring 111, the conductive members 12 comprising a contact portion 121 provided on the extension step 112 and electrically in contact with another external assembly, the contact portion 1211 having a contact point 1211 formed thereon, the contact points 1211 of each conductive member being coplane and on the same straight line.

[0046] Furthermore, the structural shape of the limiting ring 111 is not limited and is not necessarily link-shaped. For the sake of rotation, the inner wall of the limiting ring 111 is usually circular, and it contacts a structure that is connected to it to fix the position of the disc slip ring 1, while also being able to rotate while in close contact with the inner wall of the limiting ring 111.

[0047] Specifically, in a particular embodiment of the present invention, the limiting ring 111 is designed in a link shape, with a certain thickness between the inner and outer walls, thereby ensuring the mechanical properties of the limiting ring 111, and the extension step 112 is integrally molded with the limiting ring 111 and extends to both opposing sides.

[0048] According to this design, the limiting ring 111 can restrict the position of the disc slip ring 1 and can rotate around the limiting ring 111. The symmetrically positioned extension steps 112 maintain a good balance of forces at both ends during rotation, reducing wear on the disc slip ring 1 when interacting with other assemblies and extending its service life. The contact portion 121 of the conductive member 12 is easily pressed against other assemblies, and since the contact points of the contact portion 121 are on the same straight line, overall coaxiality can be ensured, thereby making the rotation process of the disc slip ring 1 more stable.

[0049] Furthermore, there are at least two extension stages 112, and they are axially or centrally symmetric on both sides of the limiting ring 111. Specifically, the conductive members 12 are provided at equal intervals on the same side of the extension step 112.

[0050] Here, "same side" refers to the same side in the axial direction of the limiting ring 111, not the same side in the radial direction of the extension step 112. In other words, the presence of the conductive member 12 on the same side of the extension step 112 prioritizes ensuring coplaneness. In a coplane state, the position of the conductive member 12 is limited, the contact point 1211 is adjusted, and coaxiality is ensured. The extension steps 112 are provided symmetrically in pairs to ensure the coaxiality of the conductive member 12 provided on them and the balance of forces acting on the entire structure of the disc slip ring 1. Therefore, the total number of extension steps 112 is not limited and may be an even number. If coaxiality is not required, the number of extension steps 112 may be an odd number such as 3 or 5, thereby achieving central symmetry and balancing the forces acting on the disc slip ring 1.

[0051] Specifically, in the embodiment of the present invention, there are two stretching steps 112, and the conductive member 12 is on the same side as the stretching steps 112 and lies on the same straight line.

[0052] One understandable aspect of this design is that the conductive members 12 are provided symmetrically and spaced apart on the extension stage 112, and the extension stage 112 is provided axially and centrally symmetrically on both sides of the limiting ring 111. During operation, the conductive members 12 of the extension stage 112 press against other assemblies, slide relative to each other, and receive the same frictional force, thereby ensuring the balance and stability of the rotation of the disc slip ring 1. When the conductive members 12 of the extension stage 112 rotate, the connection line with the contact point 1211 and the center of rotation are always on the same straight line, thereby ensuring the balance and stability of the rotation process of the disc slip ring 1.

[0053] Furthermore, a portion of the conductive member 12 is bent to form a contact portion 121, and abutment structures 122 are provided on the bent surface of each contact portion 121. The abutment structures 122 form contact points 1221 on the bent surface at positions that electrically contact other external assemblies.

[0054] Specifically, the contact portion 121 is arc-shaped, the arc curves in the opposite direction to the extension step 112, and the abutment structure 122 is provided on the arc-shaped surface of each contact portion 121.

[0055] Furthermore, the conductive member 12 itself is made of a metal material and is capable of conductivity, and the abutment structure 122 is provided to improve conductivity.

[0056] One understandable aspect of this design is that, according to this design, the contact portion 121 of the conductive member 12 easily presses against other assemblies, and by making the contact portion 121 arc-shaped, the contact area is reduced to some extent, and the contact surface is made smoother, thereby ensuring the smoothness of the process in which the conductive member 12 presses against the contact surface and slides, and thereby making the rotation process of the disc slip ring 1 more stable. The abutment structure 122 is connected to the conductive member 12 as an intermediate layer and can abut against other assemblies, thereby strengthening the contact, reducing resistance, and ensuring better conductivity.

[0057] Specifically, in certain embodiments of the present invention, the conductive member 12 is a metal dome, and in addition, in order to ensure that the conductive members 12 are on the same straight line, the arcs of the contact portions 121 must be controlled to be of the same standard and their centrifugal centers must be on the same straight line, so that the contact points 1221 of each conductive member 12 are at the same height, and specifically, the standard of the arcs is not limited here and depends on the actual needs.

[0058] Furthermore, referring to Figures 2 and 3, the disc slip ring 1 further includes a plurality of pins 13 electrically connected to the conductive member 12, and the extension step 112 has a plurality of accommodating grooves 1121 for accommodating the conductive member 12 and the pins 13.

[0059] The pin 13 is connected to the end of the conductive member 12 that is fitted into the housing groove 1121, and together with this end, it is fitted into the housing groove 1121, which can fix the conductive member 12 and the pin 13. The other end of the pin 13 extends from the housing groove 1121 and is connected to a data cable, thereby ensuring an electrical connection between the pin 13 and the conductive member 12 and enabling the transmission of electrical signals. At the same time, the conductive member 12 and the pin 13 are stably fixed, preventing the pin 13 and / or the conductive member 12 from falling off when external forces or frictional forces are applied during use or rotation processes, thus avoiding shortening the service life of the disc slip ring 1.

[0060] One understandable aspect of this design is that, according to this design, pin 13 and conductive member 12 form a simple circuit loop, where pin 13 is electrically connected to the data cable, acquires electrical signals, transmits electrical signals via conductive member 12, or receives electrical signals transmitted from an assembly or device electrically connected to conductive member 12 and transmits them to the data cable.

[0061] Specifically, the conductive member 12 and the pin 13 are fitted into the housing groove 1121, and all of them partially protrude from the housing groove 1121.

[0062] The accommodating grooves 1121 are opened at intervals in the extension steps 112, similar to the conductive member 12, and the width of the accommodating grooves 1121 corresponds to the width of the conductive member 12.

[0063] One understandable aspect of this design is that, according to this design, the conductive member 12 is fitted into the housing groove 1121, resulting in a simpler structure and easier production and processing.

[0064] Furthermore, one end of the conductive member 12 is fitted into the housing groove 1121, and the other end is suspended together with the contact portion 121. In a specific embodiment of the present invention, the suspended end of the conductive member 12 is housed in the housing groove 1121, thereby reducing the space occupied by the conductive member 12 while securing it.

[0065] One understandable aspect is that by suspending the conductive member 12 in an arc shape, the contact position and pressure when the conductive member 12 comes into contact with other assemblies can be automatically adjusted.

[0066] Furthermore, each pair of electrically connected pins 13 and conductive members 12 is either integrally molded or joined together during molding.

[0067] Specifically, the structural holder 11 has a communication groove 1123 that connects the housing groove 1121 to the outside of the structural holder. The communication groove 1123 is located on the side of the structural holder 11 opposite to the direction in which the pin 13 extends. Through the communication groove 1123, the user can check the connection state between the pin 13 and the conductive member 12, and the state in which the pin 13 and the conductive member 12 are fitted into the housing groove 1121.

[0068] Furthermore, as shown in Figures 3 and 4, in the limiting ring 111, the side closer to the conductive member 12 protrudes from the structural holder 11, and the height of the protrusion is smaller than the height of the apex of the contact portion 121 of the conductive member 12.

[0069] One understandable aspect of this design is that it improves the stability of the connection between the disc slip ring 1 and other assemblies, and limiting the height prevents the limiting ring 111 from rubbing against other assemblies, which would negatively affect the smooth rotation of the disc slip ring 1.

[0070] Furthermore, on the limiting ring 111, an annular protrusion 1111 is provided on the side where the contact portion 121 is formed, away from the conductive member 12, forming a concentric link structure with respect to the limiting ring 111.

[0071] Furthermore, in the limiting ring 111 and the annular protrusion 1111, the side wall closest to the conductive member 12 is defined as the outer wall, and the side wall opposite the outer wall is defined as the inner wall. The inner wall of the annular protrusion 1111 and the inner wall of the limiting ring 111 are on the same plane, and the diameter between the outer walls of the annular protrusion 1111 is smaller than the diameter between the outer walls of the limiting ring 111. That is, the thickness between the inner and outer walls of the annular protrusion 1111 is smaller than the thickness between the inner and outer walls of the limiting ring 111.

[0072] Furthermore, since the annular protrusion 1111 is provided close to the inner wall of the limiting ring 111, the inner wall of the annular protrusion 1111 and the inner wall of the limiting ring 111 are on the same plane.

[0073] One understandable aspect of this design is that, with 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 work in conjunction with other assemblies to further restrict position and ensure greater connection stability.

[0074] Furthermore, the structural holder 11 is further provided with a separator 1122.

[0075] The placement of the separator 1122 is not limited, and it is sufficient to ensure that the extension steps 112 are provided symmetrically. Specifically, in a particular embodiment of the present invention, the separator 1122 is provided at the location of the first conductive member 12 from the limiting ring 111 toward the extension step 112, and is also provided at the location where the five conductive members 12 are placed.

[0076] It is understood that the separator 1122 limits the spacing of the conductive members 12 and the positions of the limiting ring 111 and the conductive members 12, and also increases a predetermined weight, thereby ensuring reliability in the rotation process of the disc slip ring 1.

[0077] Referring to Figures 4 and 5, the present invention also provides a rotating conductive assembly 2 to solve the technical problems, which includes the disc slip ring 1 and a limiting plate 21 that fits the disc slip ring 1, the limiting plate 21 being provided with limiting protrusions 2111 that fit the limiting ring 111, and the disc slip ring 1 can rotate through the cooperation of the limiting ring 111 and the limiting protrusions 2111. The rotating conductive assembly 2 has the same beneficial effects as the disc slip ring 1 and will not be described in detail here.

[0078] There are usually two limiting plates 21, and the disc slip ring 1 is positioned within the two limiting plates 21 to assist in rotation or return to its original position. The limiting plate 21 closer to the conductive member 12 is as described above, while the limiting plate 21 further away from the conductive member 12 is designed to ensure proper functioning according to the actual needs or the corresponding structure of the disc slip ring 1.

[0079] Furthermore, the limiting plate 21 includes a first limiting plate 211 and a second limiting plate 212, and the disc slip ring 1 is provided on the second limiting plate 212 and can rotate through the cooperation between the limiting ring 111 and the first limiting plate 211.

[0080] Furthermore, in the rotating conductive assembly 2, the first limiting plate 211 has a sliding groove 2112 which serves as a contact portion 121 for the conductive member 12. The sliding groove 2112 is opened along the rotational trajectory of the corresponding conductive member 12, and the conductive member 12 presses against the bottom of the sliding groove 2112, thereby making an electrical connection.

[0081] Specifically, referring to Figures 6 and 7, Figure 6 is a schematic diagram of the wiring of the second circuit board, and Figure 7 is a schematic diagram of the wiring of the second circuit board.

[0082] One understandable aspect of this design is that, as the disc slip ring 1 rotates, the conductive member 12 moves within the slide groove 2112 and is always electrically connected to the bottom of the slide groove 2112, facilitating the transmission of electrical signals.

[0083] Referring to Figure 8, to solve the technical problems of the present invention, a retractable data cable assembly 3 is further provided, which includes the aforementioned rotating conductive assembly 2 and further includes a data cable 31 electrically connected to the rotating conductive assembly 2, wherein pulling the data cable 31 rotates the disc slip ring of the rotating conductive assembly 2. The retractable data cable assembly 3 has the same beneficial effects as the aforementioned rotating conductive assembly 2 and will not be described in detail here.

[0084] The foregoing are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made without departing from the principles of the present invention should be included within the scope of protection of the present invention.
