A collector ring, also known as a slip ring, is an indispensable component in the rotary antenna system and communications on the move. Except some low-end applications that have a short scanning area, most of the antenna slip rings need to integrate a radio frequency signal module. According to different industry, this radio frequency module has different names. As a professional slip ring manufacturer, JINPAT Electronics calls such module high frequency rotary joint or radio frequency rotary joint. This kind of rotary joint can support 4 channel max. The frequency range is the same as those of antenna and communication on the move devices.

 

A high frequency rotary joint, or radio frequency slip ring, is usually integrated with a through hole slip ring. The high frequency rotary joint is integrated within the through bore. Most of JINPAT hybrid radio frequency slip ring solutions take up such design. As for those that slip ring with solid shaft can’t satisfy, a through hole intermediate frequency slip ring would help.

The combination is a brand new hybrid radio frequency electrical slip ring. Generally speaking, the radio frequency slip ring is a standard product. There’s no need to adjust the signal transmission. So, it has a briefer production process. As for radio frequency slip rings with a through bore design, they are custom products. Signals consistency, delay consistency and insolation between circuits are all elements that should be consider. Few adjustments should be made before mass production.

 

In short, JINPAT Electronics is well qualified to develop stand radio frequency rotary joints and custom through hole radio frequency rotary joints. Take JINPAT Stand high frequency rotary joint LPHF-02A for example. It is very mature radio frequency slip ring model. It is a hot sale model and receive favorable feed backs from the clients. In terms of rf slip ring with through hole design, the through hole diameter can reach 120mm max.

In the development of electro-mechanical technology, computer signals like Ethernet, USB, HDMI and DP are widely applied. These applications symbolized the intense conjunction of computer technology and mechanics technology. As a frequently applied mechanical rotary conductive component of the electro-mechanical systems, slip rings need to transmit various signals mentioned above to keep pace with the modern technology. As the pioneer of the slip ring industry in China, JINPAT electronics took the initiatives in developing slip rings with capacity of transmitting these kind of signals.

Today, we will be looking into JINPAT slip rings that can transmit USB signals, HDMI signals and DP signals. Given the current technological demands, JINPAT USB slip rings can be largely divided into two groups: USB2.0 slip rings and USB3.0 slip rings. Clients can request a slip ring model to transmit solely the USB signals as well as a hybrid slip ring solution that transmit both USB signals and other signals.

JINPAT USB slip ring can integrate multiple channels. A JINPAT USB slip ring is able to support 2 USB3.0 channels and 12 USB2.0 channels. The theoretical transmission rate is 5.0Gbps while the actual transmission rate reaches over 2.0Gbps. JINPAT multi-channel USB slip ring serves mechanical system that demands large capacity and high speed data transmission. JINPAT USB slip rings are mainly used in machine vision devices, high-speed data collection, photographing equipment and testing rotary table, etc.

Aside from USB slip rings, HDMI slip rings and DP slip rings are also mainstream products. Different from SDI slip ring that can only transmit video signals, HDMI slip ring and DP slip ring take up high definition medium connectors. These two kind of slip rings adopt digital video/audio connector that is compatible with special digital devices. In both the slip ring and the electromechanical system, to transmit SDI requires coaxial cable as media. The same is truth with HDMI signals and DP signals, special HDMI cables and DP cables are needed. To make a suitable impedance matching in these two kinds of slip rings is very challenging and significant.

A hybrid JINPAT slip ring that integrate HDMI and DP signals can support versions up to HDMI1.4 and DP1.3. The hybrid slip ring can transmit video signals in 4K@30Hz and 2K@90Hz, downward compatible. Transmission bandwidth reaches up to 10.2Gbps. Just like USB slip ring, JINPAT HMDI DP slip rings support hybrid solutions that integrate other signals. JINPAT HDMI DP slip rings are mainly used in VR devices, training aids equipment and high definition video cable reels.

In the slip ring industry, custom models are generally technology intensive products. Aside from fiber optic rotary joints and high frequency slip rings, most of the standard slip ring only fulfill the task of transmitting power and signals. And that’s what mainstream electromechanical systems need. JINPAT Electronics, is a private ran slip ring company. It is the pioneer that take initiative in stepping into the virgin land of slip ring manufacturing in China. With over 25-year experience in the industry, JINPAT Electronics has developed very mature production lines of different standard slip ring models. And to keep pace with the emerging demands in the various field, JINPAT also spares no effort in innovating. JINPAT has made thousands of successful custom slip ring solutions for clients all around the world.

Among all the custom JINPAT slip rings, multi-function integrated slip rings take up a big part. There are many hybrid combinations like power, hydraulic and pneumatic integrated slip ring, electro-optical integrated slip ring and radio frequency and electrical integrated slip ring, etc. There are numerous ways of integration in related to the medium and the shapes. The most competitive and shining hybrid one is the Ethernet integrated slip ring. According to the application contexts, they can be divided in to commercial and industrial. Industrial Ethernet slip rings are applied in machinery devices while those commercial ones are applied in electromechanical systems and commercial devices.

Recently, JINPAT Electronics has received many orders of custom Ethernet integrated slip rings. We will be looking into 2 today. The first is LPT025-0610-04S-E3. It is a hybrid slip ring built on the through bore slip ring prototype. The bore diameter is 25.4mm. There are 6 10A power channels, 4 electrical signal channels and 1 Gigabit Ethernet channel. Four of the general electrical signals adopts shielded twisted pairs. As for the Ethernet part, it adopts CAT5e as leads and RJ45 as connector.

 

Another Ethernet integrated slip ring is developed from JINPAT capsule slip ring. It is coded LPC063-56A-2202-E2-12S-SD1 and takes up module design. The original structure of 22 2A channels is retained and the other parts is rebuilt in to a 100M Ethernet channel, 2 groups of 12 CAN signal channels and 1 HD-SDI channel. To avoid interference between the power channels and the signal channels, there are 1~2 shielding rings between each module. And besides, shielded wires are applied to channels conveying different kinds of signals.
