As an industrial product used for rotary connection, the slip ring can be interpreted literally, but it is worth to explore what the slip ring is composed of. Let's first look at the working principle of the slip ring. It relies on the rolling lap principle and through the ingenious internal structure design to realize the transmission of large capacity data and energy from the fixed position to the rotating position, so as to solve the problem of wiring caused by unrestricted rotation of mechanical parts. In different industries, the slip ring has different names. For example, the military industry likes to call it the collector ring, some industries like to call it the central collector, others like to call it the slip ring box, etc.
In a broad way, conductive slip ring, gas-liquid slip ring and optical fiber slip ring can be regarded as three different products. For example, the gas-liquid slip ring processes many through holes with a certain diameter inside and outside the cylindrical metal parts, and connects the rotor and stator through holes, so as to realize the unrestricted rotational transmission of gas or liquid. The optical fiber slip ring belongs to a kind of precision optical components. Its main components are optical fiber collimator and various optical lens and prism components. When it rotates, the signal transmission between stator and rotor does not need friction pairs. Therefore, the service life of optical fiber slip ring is very long and it can basically reach the level of 100 million revolutions.
Let's look at the conductive slip ring. The conductive slip ring is a product that transmits electric energy and electric signals. It relies on the contact between the brush wire or carbon brush and the copper ring, so as to realize the transmission of electric energy and signals. During operation, the copper ring keeps rotating and contacts the carbon brush or brush wire. In the process of this rotation, the action must be very smooth, and the surface of the copper ring is also very smooth. Therefore, the copper ring, smooth and sliding ring movement are one of the origins of the name of the sliding ring. In view of this feature, we can also find examples in the articles published by many scientific research institutions or colleges and universities that directly turn the copper ring in the slip ring into the slip ring.
JINPAT Electronics is a professional slip ring manufacturer with the ability of independent research and development of optical fiber slip rings, gas-liquid slip rings and various types of conductive slip rings. The slip rings here are called by the slip ring industry. They generally represent the above three kinds of slip rings for different purposes, which belong to the general name of industrial products such as "slip rings" for rotating transmission of energy and signals. Taking the name of JINPAT's slip ring as an example, the cap slip ring refers to a kind of standard slip ring with flange, which belongs to a class of conductive slip ring. The hollow shaft slip ring is a slip ring with a through hole. For convenience, many products of JINPAT adopts the same structure as the through hole slip ring, and are also divided into the hollow shaft slip ring series.
For example, JINPAT high-frequency slip ring refers to a conductive slip ring that can transmit high-frequency signals and SDI high-definition video signals. The English codes of this kind of slip ring are LPHF and LPCC. Among them, LPHF high-frequency slip ring is often integrated in the hollow shaft slip ring and forms a brand-new product with the electric slip ring. This kind of product is basically applied to all kinds of military and civilian radar antennas and mobile communication antenna bases. LPCC series high-frequency slip ring is regarded as a single channel LPHF high-frequency slip ring without shell. It can transmit both high-frequency signals and SDI high-definition video signals. The difference between the two slip rings is that the coaxial impedance used is different, one is 5 Ω and the other is 75 Ω.
