[Effects of the Invention]

[0024] Compared with the prior art, the disc slip ring, rotating conductor assembly and retractable data cable assembly according to the present invention have the following advantages:

[0025] 1. The disc slip ring of the present invention ensures a stable electrical connection with a PCB substrate during rotation. The disc slip ring includes a structural holder and a plurality of conductive members mounted on the structural holder. The structural holder includes a limit ring and extension sections extending symmetrically along the radial direction of the limit ring. The conductive members include contact sections mounted on the extension sections for electrical contact with other external assemblies, with contact points formed on the contact sections, and the contact points of each conductive member are coplanar and on the same line. This design allows the limit ring to limit the position of the disc slip ring and allows it to rotate around the limit ring, maintaining a good balance of forces experienced by both ends of the symmetrically arranged extension sections during rotation. This reduces wear on the disc slip ring when interacting with other assemblies and extends its service life. The contact sections of the conductive members are convenient for abutting with other assemblies, and the contact points of the contact sections are on the same line, maintaining overall coaxiality, thereby making the disc slip ring more stable during rotation.

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

[0027] 3. In the disc slip ring of the present invention, the conductive members are arranged at equal intervals on the same axial side of the limiting ring of the extension section. With this design, when the conductive members of the extension section 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 of the disc slip ring during the rotation process.

[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 the conductive members, and the extension section has a plurality of receiving grooves for receiving the conductive members and the pins. The pins and conductive members form a simple circuit loop, and the pins are electrically connected to a data cable to acquire electrical signals and transmit them via the conductive members, or receive electrical signals transmitted from an assembly or device electrically connected to the conductive members and transmit them to the data cable. The receiving grooves serve to restrict the conductive members and pins, preventing the disc slip ring from loosening or falling off due to rotation, resulting in reduced functionality or being discarded.

[0029] 5. In the disc slip ring of the present invention, the conductive members and pins are fitted into the receiving grooves and all partially protrude from the receiving grooves. This design allows the conductive members and pins to be fitted into the receiving grooves, and the receiving grooves can fix the conductive members and pins, making them easy to replace after long-term use or when the elements are too worn. Furthermore, the simple structure makes production and processing easier.

[0030] 6. In the disc slip ring of the present invention, the conductive member has a bent portion to form a contact portion, and a butting structure is provided on the bent surface of each contact portion, and the butting structure forms a contact point on the bent surface at a position that electrically contacts other external assemblies. With this design, the contact portion of the conductive member is convenient for abutting other assemblies, and the butting structure is connected to the conductive member as an intermediate layer, allowing it to abut other assemblies, strengthening the contact, reducing resistance, and ensuring better conductivity.

[0031] 7. In the disc slip ring of the present invention, the contact portions are arc-shaped, the arcs are bent opposite to the extension sections, and abutment structures are provided on the arc surfaces of each contact portion. By making the contact portions arc-shaped, the contact area is reduced to a certain extent, and the contact surfaces are made smoother, ensuring that the process of the conductive member pressing and sliding against the contact surfaces is smooth, 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 limit ring protrudes from the structural holder on the side closest to the conductive member, with the protruding height being smaller than the height of the apex of the contact part of the conductive member. The protruding limit ring increases the contact area between the inner wall of the limit ring and other structures, and the position of the limit ring is well defined, preventing insufficient connection and loosening during operation. The limited protruding height prevents the interface of the protruding part from contacting other structures, causing friction and reducing smooth operation, and also prevents wear and ensures the service life of the disc slip ring.

[0033] 9. In the disc slip ring of the present invention, the limiting ring has an annular protrusion on the side where the contact portion is formed, away from the conductive member, which forms a concentric link structure with the limiting ring. With this design, the annular protrusion can be mated and connected to other assemblies, further improving 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 that of the limiting ring, which makes the overall structure simpler, and the annular protrusion can cooperate with other assemblies to provide additional positional restriction and improve the stability of the connection.

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

[0036] 12. In the rotating conductive assembly of the present invention, the first limiting plate has a slide groove corresponding to the contact portion of the conductive member, the slide groove is opened along the rotation trajectory of the corresponding conductive member, and the conductive member presses against the bottom of the slide groove to be electrically connected. With this design, when the flat slide plate rotates, the conductive member moves within the slide groove and is always electrically connected to the bottom of the slide groove, facilitating the transmission of electrical signals.

[0037] 13. A retractable data cable assembly according to the present invention includes the above-described rotating conductor assembly, and further includes a data cable electrically connected to the rotating conductor assembly, wherein pulling the data cable rotates the disk slip ring of the rotating conductor assembly. Since this has the same beneficial effects as the above-described rotating conductor assembly, it will not be described in detail here. [Brief explanation of the drawings]

The specific meanings of the above terms in the present 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 stable electrical connection with a PCB substrate during rotation, the disk slip ring 1 including a structural holder 11 and a plurality of conductive members 12 provided on the structural holder 11, the structural holder 11 including a limiting ring 111 and an extension section 112 extending symmetrically along the radial direction of the limiting ring 111, the conductive members 12 including contact sections 121 provided on the extension sections 112 and electrically connected to other external assemblies, contact points 1211 are formed on the contact sections 121, and the contact points 1211 of each conductive member are coplanar and on the same straight line.

[0046] The structural shape of the limit ring 111 is not limited, and is not necessarily link-shaped. For ease of rotation, the inner wall of the limit ring 111 is usually circular, and the position of the disc slip ring 1 is fixed by abutting against an associated structure, and the limit ring 111 can rotate while adhering closely to the inner wall of the limit ring 111.

[0047] Specifically, in a specific embodiment of the present invention, the limiting ring 111 is designed in a ring shape, and there is a certain thickness between the inner wall and the outer wall, thereby ensuring the mechanical properties of the limiting ring 111, and the extension sections 112 are integrally molded with the limiting ring 111 and extend on opposite sides.

[0048] It can be seen that this design allows the limit ring 111 to limit the position of the disc slip ring 1 and also allows it to rotate around the limit ring 111, and the symmetrically arranged extension sections 112 keep the forces on both ends balanced during rotation, reduce wear on the disc slip ring 1 when working with other assemblies, and extend its service life. The contact portions 121 of the conductive member 12 are easy to press against other assemblies, and the contact points of the contact portions 121 are on the same straight line, ensuring overall coaxiality and making the rotation process of the disc slip ring 1 more stable.

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

[0050] Note that the term "same side" here refers to the same axial side of the limit ring 111, not the same radial side of the extension section 112. That is, having the conductive members 12 on the same side of the extension section 112 ensures coplanarity. In a coplanar state, the position of the conductive members 12 is limited, the contact points 1211 are adjusted, and coaxiality is ensured. The extension sections 112 are arranged symmetrically in pairs to ensure the coaxiality of the conductive members 12 and the balance of the forces acting on the entire structure of the disc slip ring 1. Therefore, the total number of extension sections 112 is not limited and may be an even number. If coaxiality is not required, the number of extension sections 112 may be an odd number, such as three or five, which will achieve central symmetry and balance the forces acting on the disc slip ring 1.

[0051] Specifically, in this embodiment of the present invention, the number of the extension sections 112 is two, and the conductive members 12 are on the same side of the extension sections 112 and on the same straight line.

[0052] It can be understood that, according to this design, the conductive members 12 are arranged symmetrically and spaced apart on the extension sections 112, and the extension sections 112 are arranged axially and centrally symmetrically on both sides of the limit ring 111, and during operation, the conductive members 12 of the extension sections 112 press against and slide relatively with other assemblies and are subjected to the same friction force, thereby ensuring the balance and stability of the rotation of the disc slip ring 1. When the conductive members 12 of the extension sections 112 rotate, the connection line with the contact point 1211 and the rotation center 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, the conductive member 12 is bent in part to form contact portions 121, and abutment structures 122 are provided on the curved surfaces of each contact portion 121, and the abutment structures 122 form contact points 1221 at positions on the curved surfaces that electrically contact other external assemblies.

[0054] Specifically, the contact portions 121 are arc-shaped, and the arcs are curved opposite to the extension sections 112 , and the abutment structures 122 are provided on the arc surfaces of each contact portion 121 .

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

[0056] It can be seen that with this design, the contact portion 121 of the conductive member 12 can easily press against other assemblies, and the arc-shaped contact portion 121 reduces the contact area to a certain extent, and the smoother contact surface ensures a smoother process of the conductive member 12 pressing and sliding against the contact surface, thereby making the rotation process of the disc slip ring 1 more stable. The abutting structure 122 is connected to the conductive member 12 as an intermediate layer, which can abut against other assemblies, strengthening the contact, reducing the resistance, and ensuring better conductivity.

[0057] Specifically, in a specific embodiment of the present invention, the conductive members 12 are metal domes. In addition, to ensure that the conductive members 12 are on the same straight line, the arcs of the contact portions 121 need to be controlled to have the same standard and the centrifugal force to be on the same straight line, so that the contact points 1221 of each conductive member 12 are at the same height. Specifically, the standard of the arcs is not limited here and depends on actual needs.

[0058] Further, referring to Figures 2 and 3, the disk slip ring 1 further includes a plurality of pins 13 electrically connected to the conductive member 12, and the extension section 112 is provided with a plurality of accommodating grooves 1121 for accommodating the conductive member 12 and the pins 13.

[0059] The pin 13 is connected to an end of the conductive member 12 that is fitted into the accommodating groove 1121, and is fitted into the accommodating groove 1121 together with this end. The accommodating groove 1121 can fix the conductive member 12 and the pin 13, and the other end of the pin 13 extends from the accommodating groove 1121 and is connected to a data cable, thereby ensuring an electrical connection between the pin 13 and the conductive member 12 and realizing the transmission of electrical signals. Meanwhile, the conductive member 12 and the pin 13 are stably fixed, and when external force or friction force is applied during use or rotation, the pin 13 and / or the conductive member 12 will not fall off, which will shorten the service life of the disc slip ring 1.

[0060] It can be seen that, according to this design, pin 13 and conductive member 12 form a simple circuit loop, with pin 13 being electrically connected to a data cable to acquire an electrical signal, transmit an electrical signal by conductive member 12, or receive an electrical signal transmitted from an assembly or device electrically connected to conductive member 12 and transmit it to the data cable.

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

[0062] The accommodation grooves 1121 are formed at intervals in the extension section 112 in the same manner as the conductive member 12 , and the width of the accommodation grooves 1121 corresponds to the width of the conductive member 12 .

[0063] It can be understood that, according to this design, the conductive member 12 is fitted into the receiving groove 1121, which has a simpler structure and is easier to produce and process.

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

[0065] It can be understood that by lifting the conductive member 12 in an arc shape, the contact position and pressure when the conductive member 12 contacts another assembly can be automatically adjusted.

[0066] Furthermore, each pair of electrically connected pin 13 and conductive member 12 is either integrally molded or jointly molded.

[0067] Specifically, a communication groove 1123 is opened in the structure holder 11 to connect the storage groove 1121 with the outside of the structure holder, and the communication groove 1123 is opened on the opposite side of the structure holder 11 in the extension direction of the pin 13, so that the user can check the connection state between the pin 13 and the conductive member 12 and the fitting state of the pin 13 and the conductive member 12 within the storage groove 1121 through the communication groove 1123.

[0068] Furthermore, as shown in FIGS. 3 and 4, the side of the limiting ring 111 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] It can be understood that this design can improve the stability of the connection between the disc slip ring 1 and other assemblies, and limiting the height can prevent the limit ring 111 from rubbing against other assemblies, which would adversely affect the smooth rotation of the disc slip ring 1.

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

[0071] Furthermore, the side wall of the limiting ring 111 and the annular protrusion 1111 that is 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] The annular protrusion 1111 is provided 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.

[0073] It can be understood that, according to this design, the inner wall of the annular protrusion 1111 and the inner wall of the limiting ring 111 are in the same plane, making the overall structure simpler, and the annular protrusion 1111 can further limit the position in cooperation with other assemblies and further ensure the stability of the connection.

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

[0075] The position of the separator 1122 is not limited as long as it can ensure that the extension stages 112 are arranged symmetrically. Specifically, in a specific embodiment of the present invention, the separator 1122 is arranged at the location of the first conductive member 12 from the limiting ring 111 towards the extension stage 112, and is also arranged at the location where five conductive members 12 are placed.

[0076] It can be 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 adds a certain weight, thereby ensuring the reliability of the disk slip ring 1 during the rotation process.

[0077] 4 and 5, in order to solve the technical problem, a rotating conductive assembly 2 is also provided, which includes the above-mentioned disc slip ring 1 and a limiting plate 21 that fits the disc slip ring 1, and the limiting plate 21 is provided with a limiting protrusion 2111 that fits the limiting ring 111, so that the disc slip ring 1 can rotate through cooperation between the limiting ring 111 and the limiting protrusion 2111. The rotating conductive assembly 2 has the same beneficial effects as the above-mentioned disc slip ring 1, so a detailed description will not be given here.

[0078] In addition, there are usually two limiting plates 21, and the disc slip ring 1 is arranged between the two limiting plates 21 to support rotation or resetting. The limiting plate 21 on the side closer to the conductive member 12 is as described above, and the limiting plate 21 on the side farther from the conductive member 12 is designed according to actual needs or the corresponding structure of the disc slip ring 1 to ensure normal functioning.

[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 mounted on the second limiting plate 212 and can rotate through cooperation between the limiting ring 111 and the first limiting plate 211.

[0080] Furthermore, in the rotating conductive assembly 2, a slide groove 2112 is opened in the first limiting plate 211 to be the contact portion 121 of the conductive member 12, and the slide groove 2112 is opened along the rotation trajectory of the corresponding conductive member 12, and the conductive member 12 is pressed against the bottom of the slide groove 2112 to be electrically connected.

[0081] Specifically, with reference to FIGS. 6 and 7, FIG. 6 is a schematic diagram of the wiring of the second circuit board, and FIG. 7 is a schematic diagram of the wiring of the second circuit board.

[0082] It can be understood that, according to this design, when 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] 8, in order to solve the technical problem, the present invention further provides a retractable data cable assembly 3, which includes the above-mentioned rotating conductor assembly 2 and further includes a data cable 31 electrically connected to the rotating conductor assembly 2, and pulling the data cable 31 rotates the disc slip ring of the rotating conductor assembly 2. The retractable data cable assembly 3 has the same beneficial effects as the above-mentioned rotating conductor assembly 2, so a detailed description will not be given here.

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