As a significant component of modern manufacturing, the demand for High Current slip rings in the shipbuilding industry is steadily increasing. Almost all modern vessels are equipped with navigation radars, making High Current slip rings indispensable components for marine navigation radars. Furthermore, some specialized ships are equipped with mechanical inertial navigation systems, which also incorporate High Current slip rings.

Typical application terminals for High Current slip rings are found in large engineering ships’ crane and hoisting equipment, as well as in special-purpose ships employing full-rotating electric propulsion systems. As a leading player in the international slip ring industry, JINPAT has developed hundreds of products for these two types of equipment, with most of them being high-voltage and High Current models. Some propulsion systems even utilize High Current slip rings with power ratings reaching several tens of megawatts. Taking the example of crane and hoisting equipment on engineering ships, whether it be specialized floating crane vessels for offshore operations, ships with deck cranes, wind turbine installation vessels, or hoisting equipment on offshore oil drilling platforms,JINPAT high-voltage and High Current slip rings have extensive applications.

Typically, smaller lifting weight shipboard cranes adopt single-function High Current slip rings that do not integrate weak signal modules or pneumatic and hydraulic modules. Among the slip rings produced by JINPAT for marine crane applications, this type is the most common,featuring a box-type structure where the stator and rotor are independently housed in a single enclosure. On the other hand, regular shipboard slip rings usually employ ordinary steel materials for the casing with relatively lower protection ratings.

However, for certain special equipment like crane slip rings used on oil drilling platforms, 304 stainless steel orhigher-grade steel materials are utilized, and the thickness of the plate is several times that of the casing used in regular crane slip rings, enabling the product to meet specific explosion-proof ratings. Therefore, slip rings with explosion-proof capabilities have higher protection ratings. A few shipboard High Current slip rings for marine crane applications may adopt a cylindrical integral structure, which facilitates achieving higher protection ratings.

As for propulsion system applications, JINPAT offers a variety of products, including regular single high-power modules and multi-module slip rings integrating High Current modules, pneumatic and hydraulic slip rings, and electrical signal slip rings. In specialized slip rings for propulsion systems, there is a category of products characterized by ultra-high operating voltages, usually exceeding 3300VAC, with tremendous power transmission capabilities, often exceeding one megawatt. JINPAT has successfully delivered multiple specialized slip rings with power transmission capacities of up to 7.5 megawatts and has the capability for research,development, and mass production of specialized slip rings with a maximum power of 15 megawatts.

The High Current Ethernet Slip Ring is a specialized slip ring device designed for transmitting both high currents and Ethernet signals. Unlike traditional Ethernet slip rings, the high current Ethernet slip ring is capable of simultaneously transmitting high currents and high-speed Ethernet signals, making it suitable for scenarios where large currents and data need to be transmitted in rotating or moving equipment.

 

In various industrial and technological applications, the need to transmit both high currents and Ethernet signals is quite common. For example, large machinery, industrial robots, automation equipment, stage lighting, and camera equipment often require high-power power supplies and real-time data and control signal transmission. In such cases, the high current Ethernet slip ring plays a crucial role, enabling devices to continuously and stably transmit currents and data during rotational movements.

 

The design of the high current Ethernet slip ring takes into consideration the high load requirements for current transmission. It typically incorporates high-power conductive materials and special structures to ensure the stability and reliability of current transmission. Additionally, it integrates Ethernet signal transmission channelsto ensure high-speed data transfer unaffected by rotational movements.

 

Recently, JINPAT developed a new high current Ethernet signal integrated slip ring, with the model number LPA000-04100-0820-0408-07E3. The power loop of this slip ring integrates 4channels of 100A, 8 channels of 20A, and 4 channels of 8A current pathways.Among them, the 4 channels of 100A use a carbon brush structure as a separate module. The remaining 12 channels of current pathways and Ethernet signal pathsare integrated within the hollow shaft slip ring, forming another module. This high current integrated slip ring accommodates up to 7 Ethernet signal pathsand uses aviation plug connections. Its development marks a significant advancement for JINPAT in the field of multi-channel Ethernet signal integration technology.

 

 

Besides this integrated slip ring, as an experienced slip ring manufacturer, JINPAT offers various products that integrate large current and Ethernet signal pathways. For example, the LPA000-03100-01PE-0220-1002-02E3-03E2-04S-01A represents a multi-module integrated large current slip ring, including 2 channels of Gigabit Ethernet and 3 channels of Fast Ethernet. Additionally, it features an extra gas-liquid module, although it only includes 1 gas pathway.

 

In summary, the High Current Ethernet Slip Ring is a powerful slip ring device that meets the demands of transmitting high currents and high-speed Ethernet signals. It provides an efficient and stable power and data transmission solution for rotating and moving equipment and systems.

Slip rings are critical components that enable the transfer of power and signals in a 360° range, and they are widely used in electromechanical products across various industries. In the field of consumer electronics, slip rings are also employed in certain specialized products such as high-end toys, multi-rotor drones, and stabilizing gimbals.The slip rings used in these products typically have small dimensions and are lightweight. One notable example is the slip ring solution provided by JINPAT forconsumer electronics applications. The JINPAT LPMS ultra-miniature slip ring series, with a diameter usually below 10mm, includes a few customized pancake slip ring products.

As a pioneer among international slip ring manufacturers, JINPAT LPMS ultra-miniature slip ring series currently represents one of the smallest slip rings available in the global market. The smallest product in the series has a diameter of only 5.5mm. If there is a clear demand for even smaller diameter slip rings in the market, JINPAT can develop ultra-miniature slip rings with a diameter of 4.5mm. Presently, the standard LPMS ultra-miniature slip rings offer a maximum number of 15 signal channels and have a diameter not exceeding 7.1mm, with a total wire weight not exceeding 15 grams.

One distinctive feature of JINPAT LPMS ultra-miniature slip rings is their ability to support the mixed transmission of both power and signals. However, they are limited to transmitting relatively simple signals. For more complex signals such as Ethernet or USB, customization is required. Leveraging the advantages of the LPMS series ultra-small diameter,JINPAT has developed numerous signal-integrated slip rings for specialized applications, including USB 2.0, SDI high-definition video signal, and gigabit Ethernet signal slip rings. Among these ultra-miniature customized slip rings application terminals, cruise missiles can be considered the most unique. The slip rings are installed inside the optical-electricturret of the cruise missile to support the transmission of power, SDI, or other signals.

As a weapon that has gained popularity on the battlefield in recent years, cruise missiles are characterized by their portability and precision in striking targets. However, they also impose strict limitations on the size and weight of their components. Therefore, for ultra-miniature slip rings like JINPAT LPMS series, which weigh only a few grams, the optical-electric turret of cruise missiles is an ideal application terminal. Taking the example of the JINPAT LPMS-15 standard slip ring, it can be customized to accommodate SDI, Ethernet, and other signal channels, meeting the transmission requirements of common signals in small optical-electricturrets. Through optimized design, it can also support the operation of small aircraft or cruise missiles at altitudes above 8000 meters. This data is not derived from thin air but is based on conclusions drawn from the summary of various ultra-miniature slip ring cases provided by JINPAT for the consumer electronics industry and other sectors over the years.

As a typical representative of the high-precision manufacturing industry, the chip manufacturing industry widely adopts various automation machines to improve production efficiency and quality. Among these automation machines, slip rings play an important role as essential electrical connection devices. JINPAT, as a leading international slip ring manufacturer, provides corresponding slip ring solutions for key processes and equipment in wafer fabrication, chip etching, and packaging.

Let’s first look at the slip ring cases provided by JINPAT for packaging equipment. These cases cover highly complex multi-module products as well as seemingly ordinary standard products. One representative example is the LPS separate standard slip ring. These slip ring products have no bearings or casings, and the stat or brush wires and rotors are exposed. The standard products of the LPS separate slip rings support a 2A current throughout the series and are designed with gold-to-gold contact points, enabling mixed transmission of signals and current. In precision chip packaging equipment, the most commonly used model of the LPS separate slip rings is the LPS-12, which is responsible for 360° power transmission within the machine and does not involve signal transmission issues.

Due to their small size, LPS series slip rings are primarily suitable for small-scale electromechanical devices, and the chip manufacturing industry is no exception. For large-scale packaging equipment, slip ring solutions with more functions and stronger signal and current transmission capabilities need to be chosen. In general, hollow shaft slip rings and customized multi-module products are commonly used in medium to large-scale electromechanical devices. The latest product developed by JINPAT,the LPT000-0802-02L-03A, is a multi-module slip ring integrated with gas,liquid, and electricity. It integrates 8 channels of 2A current, 2 channels of liquid transmission, and 3 channels of gas transmission, meeting the requirements for transmitting   special liquids and gases in packaging equipment.

JINPAT slip ring solutions are widely used in the chip packaging industry, providing manufacturers with reliable electrical connections. Whether it is a small packaging machine or a large packaging equipment, JINPAT slip ring products meet their respective needs,ensuring the reliability of signal transmission, data collection, and power supply. By collaborating with JINPAT, the chip manufacturing industry can obtain high-quality slip ring solutions, driving the industry’s development and progress.

Slip rings for medical robots are a crucial technology in the field of medical devices. As precision electromechanical products, medical robot slip rings come in various types. In the following text, we will provide a brief analysis of the types of slip rings used inmedical robots.

Before delving into medical robot slip rings, we can categorize medical robots into two main types based on their functionality and external appearance. The first type is the robotic arm-style medical robot, which resembles most industrial robots. These simpler productsare used for lifting or transporting heavy objects. On the other hand, high-endrobotic arm-style medical robots are equipped with integrated devices on the end effector, allowing them to perform lesion detection or treatment by utilizing the endless rotation of the limbs.

JINPAT has developed slip rings specifically for robotic arm-style medical robots. These slip rings employ JINPAT’s patented structure of high-lifetime welded robot hollow shaft slip rings,meeting the requirements for stable operation, reliability, and lifespan underhigh-intensity working conditions. This highly reliable hollow shaft slip ring structure is not limited to medical robot applications but is also utilized inmedium to large specialized treatment equipment and other industries.

The second type of medical robots,represented by da Vinci surgical robots, typically have fewer degrees of freedom in their mechanical arms. However, they require much stricter control sensitivity and precision. JINPAT LPC, LPM, and LPMS series of capsule sliprings meet the demands of these high-precision surgical robots in terms of starting torque, smooth operation, lifespan, stability, and reliability. These capsule slip rings also support customization of Ethernet, USB, SDI, and various analog and digital signal types to fulfill the signal transmission requirements of precision medical robots. The excellent structure and expandability of these capsule slip rings have led to their widespread use in the field of medical robots.

In addition to capsule slip rings, JINPAT also offers small bore hollow shaft series and pancake series slip rings for selection in medical robots. The small bore hollow shaft slip rings have the advantages of small space occupation, long lifespan, and the ability to customize a wide variety of signal types. The pancake slip rings, with their inherently low thickness advantage, are suitable for medical robots with lowaxial space requirements, making them highly attractive for specialized applications.

Overall, the diverse types of slip rings provided by JINPAT cater to the specific needs of medical robots, enabling reliable and efficient operation in various medical applications.

As a widely used component in various industries, slip rings find extensive applications. JINPAT, an experienced slip ring manufacturer, offers thousands of different types of slip rings for numerous industries. Among these industries, the field of film and television production is relatively niche,with a lesser demand for slip rings. In the film and television industry, slip rings are primarily used in film production and auxiliary equipment, such as photography booms, portable professional stabilizers, and other DIY accessories. Additionally, in high-definition television broadcasting setups, slip rings are utilized in systems like the “Fei Mao” system and television OB (Outside Broadcasting) vans.

 

Taking professional stabilizers as an example, their yaw axis can rotate 360 degrees, combined with the pitch and roll axes, allowing the attached camera equipment to capture various desired shots. Inside the yaw axis of professional stabilizers, a dedicated miniature slip ring is installed. The slip rings provided by JINPAT for such stabilizers belong to the LPMS series, with a range of 8 to 15 circuits. Models include LPMS-08D, LPMS-10C, LPMS-12U,LPMS-15, etc. These products have a maximum diameter of 7.4mm and are controlled within a minimum of 5.5mm. Compared to slip rings used in other auxiliary photography equipment, those used in portable professional stabilizers are simple in both functionality and structure.

 

Photography booms are used to support heavier professional-gradephotography equipment. Many booms come equipped with heavy-duty stabilizers,which also require the support of slip rings. Slip rings developed by JINPAT for photography booms are mainly based on partial LPM and LPC1C standard products. The LPM series standard products can transmit power while supporting the mixed transmission of simple signals and currents, but they do not support high-definition video signal transmission. On the other hand, the LPC1C series integrates LPCC series single-channel products capable of transmitting up to12G-SDI high-definition video signals. If there is a need in the market for transmitting more than one channel of high-definition video signals, the ideal choice would be the LPHF series high-frequency slip rings by JINPAT. By replacing the external coaxial line with a 75-ohm impedance cable, these slip rings can transmit 12G-SDI signals. Therefore, the LPHF series high-frequency slip rings are the perfect tool for transmitting multiple channels of 12G-SDIsignals in the film and television industry’s DIY equipment.

 

In photography studio shooting environments, proper lighting setup is crucial for capturing ideal shots. In addition to fixed lighting, occasional design of lighting equipment is necessary for assistance in photography. For example, on the set of the film “The Wandering Earth 2,” the crew designed a large searchlight turntable to simulate the required ambient light.A slip ring is installed in the center of the turntable. Since the turntable is manually operated, there is no need to add control signal pathways to the slip ring used, simplifying the structure and reducing costs. Due to the high power of the searchlights, standard-hole-type slip rings capable of transmitting a current of 15A are used to meet the requirements. The specific number of circuits and aperture sizes can be chosen based on practical considerations.

A slip ring is an important component inelectromechanical equipment that enables 360° rotation for the transmission of electrical energy, electrical signals, optical signals, compressed air,liquids, and other media. The naming of slip rings varies depending on the transmitted medium. For example, fiber optic slip rings are specifically designed for transmitting optical signals and require excellent optical performance. Gas-liquid slip rings are used for transmitting liquids and air,demanding high precision and sealing requirements for component manufacturing.Electrical slip rings are capable of transmitting electrical energy and signals, supporting the transmission of over 30 different signal types.Different sizes of electrical slip rings exhibit significant differences in lifespan and electrical performance due to variations in the friction pair and other structural elements.

Within JINPAT slip ring product line, the through-hole slip ring is a strategic product widely applied in various large-scale equipment. With the popularization of automation and electromechanical integration in industries, common computer signals such as USB and Ethernet have long been integrated into slip rings. However, due to the limitations of the through-hole structure, signals like USB 3.0, HDMI, and DP can not be transmitted through this type of slip ring. In contrast, Ethernet signals, with their unique signal characteristics, are more commonly found in through-hole slip rings. As a well-established slip ring manufacturer with over20 years of industry experience, JINPAT has customized nearly a thousand through-hole Ethernet signal slip rings for customers.

JINPAT demonstrates exceptional technical capabilities in the field of Ethernet signal slip rings, particularly in terms of the maximum supported aperture. In through-hole slip rings, the transmission of signals is closely related to the size of the through-hole. Currently,JINPAT 100 Mbps Ethernet slip rings can achieve transmission within a maximum300 mm aperture, while their 1 Gbps Ethernet slip rings can transmit within a maximum 180 mm aperture. As JINPAT continues to improve its products and technologies, these figures are expected to be further surpassed in the future,resulting in even larger apertures for through-hole Ethernet signal slip rings.

JINPAT delivers a large number of Ethernet signal slip rings every month. Among these products, apart from capsule Ethernet slip rings specifically developed for monitoring devices, the majority consists of hollow shaft series Ethernet slip rings. For instance, the latest product introduced, LPT038-02E3, is a through-hole slip ring without a power ring, integrating only two channels of 1 Gbps Ethernet signals. JINPAT also offers other newly developed through-hole Ethernet signal integrated slip ring models, including LPT045-0410-04S-01E3, LPT030-0505-04S-01E3,LPT050-0405-01PE-01E3, LPT130-0812-08S-E2-02E3, and more.

Space electric slip rings are slip rings used in artificial spacecraft such as satellites, manned spacecraft, and space stations. They can be classified into two types based on environmental conditions: those used in unmanned spacecraft and those used in manned spacecraft. Besides the similarity of operating in a micro gravity environment,their main difference lies in the different operating temperature ranges.Electric slip rings inside manned spacecraft operate in a temperature environment that is constant, suitable for human survival, and maintained at as table level of humidity and pressure. On the other hand, electric slip rings in unmanned spacecraft, although installed inside equipment like attitude control systems and protected by a layer of polyimide, still experience significant temperature variations.

In the conducted testing of electric slip rings in the laboratory, two types were involved: pancake type and column type.The column type electric slip rings employ a brush and wire friction pair,while the pancake type electric slip rings use a carbon brush friction pair.Both of these products used in the experiment lack an outer shell, allowing astronauts to visually observe the wear process of the slip ring brushes in a vacuum micro gravity state, as well as the generation of metal debris.Additionally, the operation of carbon brushes produces carbon powder, enabling direct observation of the process of carbon powder generation in orbit,including the formation of clusters or floating phenomena in a vacuum.

According to the naming convention of JINPAT,the electric slip rings used in this experiment can be classified into two series: pancake-type LPKS and separate-type LPS. Both of these slip rings have a simple structure, and their design and manufacturing do not present significant challenges. The key breakthrough of this experiment lies in achieving long-term recording and observation by astronauts of the generation of metal debris and carbon powder clusters during the operation of electric slip rings in a micro gravity environment. This data, obtained using two commonly used friction pairs, provides important information on the wear process and the generation of debris clusters under vacuum conditions. This data serves as valuable references for the improvement and optimization of future models of space electric slip rings.

The aerospace industry is characterized by a high level of centralization. Although JINPAT is a leading international slip ring manufacturer, they have not yet ventured into this field due to a lack of vacuum high-low temperature impact test equipment. However, with the participation of some enterprises in the aerospace industry, JINPAT, as a supporting manufacturer of electric slip rings, will have increasing opportunities to get involved in this field.
