Description

Technical Field

[0001] This utility model belongs to the field of slip ring technology, specifically relating to a double-ended power supply quick-connect slip ring. Background Technology

[0002] Slip rings, as key devices for transmitting power and signals between rotating parts and stationary structures, play a vital role in numerous fields. Traditional slip rings are inconvenient to operate and typically only allow power to be supplied from one side. This design is significantly insufficient in applications requiring high power supply flexibility, failing to meet the demands of equipment requiring efficient and stable power transmission and convenient operation. Therefore, a dual-end powered quick-connect slip ring was designed to address these issues.

[0003] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solutions of this utility model and facilitating understanding by those skilled in the art. It should not be assumed that these technical solutions are known to those skilled in the art simply because they have been described in the background section of this utility model. Utility Model Content

[0004] To overcome the shortcomings of the prior art, the purpose of this utility model is to provide a dual-end power supply quick-connect slip ring.

[0005] To achieve the above and other related objectives, the technical solution provided by this utility model is: a dual-end power supply quick-connect slip ring, comprising: main body; An inner conductor is disposed inside the main body, and a socket is provided on the inner conductor in a first direction; A conductive shaft is provided through the main body. The conductive shaft is pluggable and rotatably disposed in the insertion hole. The axial length of the conductive shaft is greater than the length of the main body in a first direction. The portion of the conductive shaft corresponding to the insertion hole has several evenly distributed annular grooves along the circumferential direction. A first side conductor is located on one side of the inner conductor in a second direction, and one end of the first side conductor extends out of the main body. A second side conductor is located on the other side of the inner conductor in a second direction, and one end of the second side conductor extends out of the main body. When the conductive shaft is in the inserted state, it is electrically connected to the inner conductor, the first side conductor, and the second side conductor.

[0006] In this design, the protruding ends of the first conductor and the second conductor are on the same side, which facilitates the connection of the two ends to the power supply.

[0007] Furthermore, the first side conductor includes a side clamping plate, and a gripping claw structure is provided on one side of the side clamping plate. The gripping claw structure is composed of an upper arc-shaped structure and a lower arc-shaped structure that are corresponding to each other. Both the upper arc-shaped structure and the lower arc-shaped structure are composed of multiple arc-shaped strips evenly arranged. The arc-shaped strips of the upper arc-shaped structure and the arc-shaped strips of the lower arc-shaped structure are bent towards each other. The structure of the arc-shaped strips is adapted to the structure of the annular groove. The lower end of the side clamping plate is also provided with a bending portion, which is located on the same side as the gripping claw structure.

[0008] Furthermore, a first side locking position is provided on the side of the inner conductor where the first side conductor is installed, and an installation port communicating with the socket is provided at the first side locking position. A lower locking position communicating with the first side locking position is provided at the lower end of the inner conductor. An installation cavity is provided radially on the inner side of the socket. The side locking plate is locked in the first side locking position and the end away from the bending part extends out of the first side locking position. The bending part is located in the lower locking position. The claw structure passes through the installation port and is provided in the installation cavity. The inner diameter of the claw structure in the unforced state is smaller than the inner diameter of the socket. The arc-shaped strip is correspondingly engaged with the annular groove.

[0009] Furthermore, a second side slot is provided on one side of the inner conductor where the second side conductor is installed. The second side conductor is secured in the second side slot and both ends of the second side slot extend out of the second side slot, with one end extending out of the main body and the other end extending to be flush with the outer surface of the main body.

[0010] Furthermore, a bearing is provided on both sides of the inner conductor in the first direction, and a washer is provided on both sides of each bearing. Both the bearing and the washer are coaxially arranged with the insertion hole, and the inner diameters of the bearing and the washer are adapted to the diameter of the conductive shaft. In this design, when the conductive shaft is inserted into the insertion hole, both the bearing and the washer are fitted onto the conductive shaft.

[0011] Furthermore, grooves are formed at both ends of the inner conductor in the first direction, and the bearing and its inner washer are embedded in the corresponding grooves. In this design, the embedded bearing and washer make the structure more stable.

[0012] Furthermore, sealing rings are provided on both sides of the inner conductor in the first direction. These sealing rings are located outside the bearing and are coaxially arranged with the insertion hole. The inner diameter of the sealing ring is adapted to the diameter of the conductive shaft. In this design, when the conductive shaft is inserted into the insertion hole, the sealing rings are fitted onto the conductive shaft.

[0013] Furthermore, the inner conductor is provided with clamping rings on both sides in the first direction. The clamping rings are located outside the sealing ring and are coaxially arranged with the insertion hole. The inner diameter of the clamping rings is adapted to the diameter of the conductive shaft. In this solution, when the conductive shaft is inserted into the insertion hole, the clamping rings are sleeved on the conductive shaft.

[0014] Furthermore, the main body has mounting grooves at both ends in the first direction, and the sealing ring and the clamping ring are embedded in the corresponding mounting grooves. In this design, the embedding of the sealing ring and the clamping ring makes the structure more stable.

[0015] Furthermore, the inner conductor includes an upper conductor and a lower conductor, which are detachably connected; the main body includes an upper shell and a lower shell, which are detachably connected. In this design, both the inner conductor and the main body are composed of two detachable parts, facilitating the installation and maintenance of the internal structure.

[0016] Due to the application of the above technical solution, the beneficial effects of this utility model compared with the prior art are as follows: This utility model features a dual-end power supply quick-connect slip ring that supports dual-end power supply, providing more flexible and stable power supply for equipment. It effectively solves the limitations of traditional slip rings with single-sided power supply, meeting the power supply flexibility requirements of different application scenarios. It also has a quick-plug function, facilitating equipment installation, debugging, and maintenance.

[0022] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0023] Example: This embodiment provides a dual-end powered quick-connect slip ring, including: Main Body 1: See Appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the main body 1 has two ends (end A and end B) for connecting to a power source, ensuring that power can be supplied from both sides simultaneously. The main body 1 is made of high-strength materials to ensure structural stability and reliability. Its internal design provides ample installation space and support for other components. The main body 1 includes an upper housing 101 and a lower housing 102, which are detachably connected. The main body 1 consists of two detachable parts, facilitating the installation and maintenance of the internal structure.

[0024] Inner conductor 2: See appendix Figure 8 As shown, the inner conductor 2 is disposed inside the main body 1, and a socket 201 is formed on the inner conductor 2 in the first direction. The inner conductor 2 is used to transmit power and is made of a highly conductive and wear-resistant material, such as copper alloy. This material can effectively reduce resistance and energy loss, while also possessing good wear resistance, ensuring long-term stable power transmission. The inner conductor 2 includes an upper conductor 202 and a lower conductor 203, see Appendix Figure 10As shown, the upper conductor 202 and the lower conductor 203 are detachably connected, and are electrically connected when connected; the inner conductor 2 consists of two detachable parts, which facilitates the installation and maintenance of the internal structure.

[0025] Conductive axis 3: See appendix Figure 3 Appendix Figure 4 Appendix Figure 6 and attached Figure 7 As shown, the conductive shaft 3 passes through the main body 1 and is pluggable and rotatable in the insertion hole 201. The axial length of the conductive shaft 3 is greater than the length of the main body 1 in the first direction. (When the conductive shaft 3 is in the inserted state, both ends of it extend out of the main body 1.) The part of the conductive shaft 3 corresponding to the insertion hole 201 has several evenly distributed annular grooves 301 along the circumference. The conductive shaft 3 is a structure that can be quickly inserted and pulled out, which facilitates the connection and disconnection of the power supply. The design of the annular grooves 301 of the conductive shaft 3 ensures that the electrical connection with the docking part (claw structure 402) can be quickly established and disconnected during the insertion and removal process, while ensuring good contact performance.

[0026] First side conductor 4: See appendix Figure 3 and attached Figure 9 As shown, the first side conductor 4 is located on one side of the inner conductor 2 in the second direction, and one end of the first side conductor 4 extends out of the main body 1 to form end A; see appendix. Figure 5 and attached Figure 7 As shown, the first side conductor 4 includes a side clamping plate 401. A gripper structure 402 is provided on one side of the side clamping plate 401. The gripper structure 402 is composed of an upper arc-shaped structure 4021 and a lower arc-shaped structure 4022, which are correspondingly arranged. Both the upper arc-shaped structure 4021 and the lower arc-shaped structure 4022 are composed of multiple arc-shaped strips evenly distributed. The arc-shaped strips of the upper arc-shaped structure 4021 and the arc-shaped strips of the lower arc-shaped structure 4022 are bent towards each other. The structure of the arc-shaped strips is adapted to the structure of the annular groove 301. A bending part 403 is also provided at the lower end of the side clamping plate 401. The bending part 403 is provided on the same side as the gripper structure 402.

[0027] See appendix Figure 8 and attached Figure 10As shown, a first side locking position 204 is provided on the side of the inner conductor 2 where the first side conductor 4 is installed. An installation opening 205 communicating with the insertion hole 201 is provided at the first side locking position 204. A lower locking position 206 communicating with the first side locking position 204 is provided at the lower end of the inner conductor 2. An installation cavity 207 is provided radially on the inner side of the insertion hole 201. The side locking plate 401 is locked within the first side locking position 204, and one end of it, away from the bending portion 403, extends out of the first side locking position 204 (this end is the end extending out of the main body 1). The bending portion 403 is located at the lower locking position 206. Inside the 6th cavity, the claw structure 402 passes through the mounting port 205 and is located in the mounting cavity 207. The upper arc-shaped structure 4021 is located on the upper side of the mounting cavity 207, and the lower arc-shaped structure 4022 is located on the lower side of the mounting cavity 207. The inner diameter of the claw structure 402 when it is not under force is smaller than the inner diameter of the insertion hole 201. The arc-shaped strip is engaged with the annular groove 301. When the conductive shaft 3 is inserted into the insertion hole 201, it will open the claw structure 402 slightly. After the arc-shaped strip is engaged with the annular groove 301, the claw structure 402 will hold the conductive shaft 3 tightly to achieve conductive connection.

[0028] Second side conductor 5: See appendix Figure 1 Appendix Figure 6 and attached Figure 7 As shown, the second side conductor 5 is located on the other side of the inner conductor 2 in the second direction, and one end of the second side conductor 5 extends out of the main body 1 to form end B; see appendix. Figure 8 and attached Figure 10 As shown, a second-side retaining position 208 is provided on one side of the inner conductor 2 where the second-side conductor 5 is installed. The second-side conductor 5 is secured within the second-side retaining position 208, with both ends extending out of the second-side retaining position 208. One end extends out of the main body 1, and the other end extends to be flush with the outer surface of the main body 1. (A mating connector can be provided at the end flush with the outer surface of the main body 1.) When the conductive shaft 3 is in the inserted state, it is electrically connected to the inner conductor 2, the first side conductor 4, and the second side conductor 5. The protruding end of the first side conductor 4 is on the same side as the protruding end of the second side conductor 5, which facilitates the connection of the two ends to the power supply.

[0029] Bearing 6: See Appendix Figure 2 and attached Figure 11 As shown, the inner conductor 2 has a bearing 6 on both sides in the first direction, and a washer 7 on both sides of each bearing 6. Both the bearing 6 and the washer 7 are coaxially aligned with the insertion hole 201. The inner diameters of the bearing 6 and the washer 7 are matched to the diameter of the conductive shaft 3. When the conductive shaft 3 is inserted into the insertion hole 201, the bearing 6 and the washer 7 are fitted onto the conductive shaft 3. The inner conductor 2 has grooves 209 at both ends in the first direction, and the bearing 6 and its inner washer 7 are embedded in the corresponding grooves 209. The embedded bearing 6 and washer 7 make the structure more stable.

[0030] The bearing 6 is used to support the rotating part of the main body 1, namely the conductive shaft 3. The bearing 6 adopts a design with a low coefficient of friction as much as possible to reduce wear and improve rotational stability. The types of bearing 6 include, but are not limited to, spherical bearings. Other types of bearings with low coefficients of friction are within the protection scope of this patent document. The bearing 6 is preferably made of high-quality materials and manufactured with high precision to improve the stability of the slip ring when rotating at high speed.

[0031] Sealing ring 8 and compression ring 9: See appendix Figure 1 and attached Figure 11 As shown, the inner conductor 2 is provided with sealing rings 8 on both sides in the first direction. The sealing rings 8 are located outside the bearing 6 (including the washer 7, actually outside the outer side of the outer washer 7 of the bearing 6). The sealing rings 8 are coaxially arranged with the insertion hole 201, and the inner diameter of the sealing rings 8 is adapted to the diameter of the conductive shaft 3. When the conductive shaft 3 is inserted into the insertion hole 201, the sealing rings 8 are fitted onto the conductive shaft 3. The inner conductor 2 is also provided with clamping rings 9 on both sides in the first direction. The clamping rings 9 are located outside the sealing rings 8, and the clamping rings 9 are coaxially arranged with the insertion hole 201. The inner diameter of the clamping rings 9 is adapted to the diameter of the conductive shaft 3. When the conductive shaft 3 is inserted into the insertion hole 201, the clamping rings 9 are fitted onto the conductive shaft 3. The main body 1 has mounting grooves 103 at both ends in the first direction, and the sealing rings 8 and clamping rings 9 are embedded in the corresponding mounting grooves 103. The embedded sealing rings 8 and clamping rings 9 make the structure more stable.

[0032] The sealing ring 8 and the clamping ring 9 ensure a tight seal and prevent the ingress of external substances, allowing the slip ring to be used in environments with acidic or alkaline gases. The sealing ring 8 and the clamping ring 9 are made of high-strength, wear-resistant materials such as rubber or polyurethane. The sealing ring 8 and the clamping ring 9 effectively block the intrusion of dust, moisture, and other impurities, protecting internal components from damage while ensuring the electrical insulation performance of the slip ring.

[0033] The slip ring designed in this invention is mainly used in chain-type horizontal electroplating equipment. In the power transmission structure of traditional chain-type horizontal electroplating equipment, the length of the conductive shaft is relatively large (usually 1.5m~1.8m). Unilateral power connection can easily lead to uneven power distribution between the near and far ends of the conductive shaft. However, the slip ring design allows the power to be input from the middle of the conductive shaft, which is equivalent to reducing the distance between the near and far ends by half, resulting in a more uniform power distribution.

[0034] This utility model features a dual-end power supply quick-connect slip ring that supports dual-end power supply, providing more flexible and stable power supply for equipment. It effectively solves the limitations of traditional slip rings with single-sided power supply, meeting the power supply flexibility requirements of different application scenarios. It also has a quick-plug function, facilitating equipment installation, debugging, and maintenance. It is suitable for various equipment that requires efficient and stable power transmission and convenient operation.

[0035] Related application areas: Industrial automated production lines: In industrial automated production lines, numerous rotating devices such as robotic arms and rotary tables work collaboratively, placing extremely high demands on the stability and continuity of power supply. Traditional single-sided power supply slip rings may experience unstable operation or even shutdown when faced with complex production conditions due to sudden high power demands or power line failures. The double-sided power supply slip ring of this invention acts like two "power lifelines" for the production line. When power supply to one side fluctuates or fails, the other side can immediately replenish power, ensuring the normal operation of the equipment. For example, in an automobile manufacturing production line, robotic arms need to frequently perform high-precision gripping and assembly actions. The double-sided power supply slip ring ensures stable power support for the robotic arms during high-speed movements, avoiding motion deviations caused by insufficient power, thus improving production efficiency and product quality.

[0036] Wind power generation systems: Wind turbine blades rotate continuously under varying wind speeds and directions, requiring a stable and sufficient power supply for energy conversion and transmission. Traditional single-sided power supply slip rings are prone to overheating and wear under high loads and prolonged operation, affecting power generation efficiency and equipment lifespan. Dual-ended power supply slip rings, on the other hand, can evenly distribute high load demands across both ends, reducing the burden on each power supply line. It's like equipping the wind turbine with two "energy transmission guardians"; even if one "guardian" experiences a minor malfunction, the other can quickly take over the main power supply task. For example, in offshore wind farms, the harsh marine environment places higher demands on equipment reliability. Dual-ended power supply slip rings ensure stable power generation of wind turbines under complex sea conditions, reducing downtime for maintenance due to power supply issues and improving power generation efficiency.

[0037] Aerospace Equipment: The aerospace field demands extremely high reliability and safety from its equipment; any power supply failure can lead to serious consequences. In rotating components of aircraft, such as radar antennas and engine control systems, a failure of a traditional single-sided power supply slip ring can affect navigation, communication, and flight safety. The redundant design of dual-ended power supply slip rings provides reliable power assurance for aerospace equipment. It's like adding double insurance to the aircraft's electrical system; when one power supply fails, the other can immediately take over power transmission, ensuring the normal operation of critical functions. For example, in satellite attitude control systems, dual-ended power supply slip rings ensure stable operation of rotating components in space for extended periods, preventing attitude control failures due to power outages and guaranteeing normal satellite operation and data transmission.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
