What is the working principle of conductive slip ring?
Slip rings
using conductive parts of sliding or rolling contact, electrostatic
coupling or electromagnetic coupling, the antenna mount rotating parts
and stationary parts passed between electrical signal and power device.
In rotating components drive components, measuring element, and control
components, must from the room to offer their transmission control
signal and power supply. This requires a variety of slip ring assemblies
to transmit signals and energy. Some radar need to rotate the
connection line up to more than one hundred. Slip ring components
according to the transmission signal frequency can be divided into: the
low-frequency slip ring slip ring, intermediate and high frequency
rotating hinge. Slip ring usually means only the first two. Slip ring
component's performance indicators are: insulation resistance and
contact resistance, medium intensity and crosstalk. For intermediate
frequency slip ring, because high frequency consider shielding,
impedance matching, noise voltage, etc. First of all to ensure the
reliable contact, in the structural design of straight through to ensure
that all lines. , therefore, request the material of brush conductive
performance is good, the pressure to the slip ring, appropriate to the
eccentricity of the slip ring and shaking a little, good wear resistance
and friction torque is small, easy to maintain.
Low slip ring
Use of sliding contact of the low frequency signal and energy transmission slip ring assembly . There are the usual cylindrical slip ring slip ring slip ring and the differential two kinds. Cylindrical conductive ring slip ring is divided into flat ring and V -ring . Conductive ring more wear-resistant material commonly used pure copper, silver and gold coins . Brush with palladium, gold alloy or gold-plated copper wire brushes and synthetic graphite brushes . If a larger number of slip rings , a cylindrical slip ring from the upper and lower two brushes and a differential adapter plate (Figure 1 Schematic differential slip ring ) , but its axial dimension is large, the differential slip ring can significantly reduce the axial dimension , to reduce the volume and weight. Differential slip ring from the upper and lower two brushes and a differential adapter plate components. With the antenna position on the rotating brush , the brush is fixed, the differential adapter plate up and down two contact pieces , and the corresponding contact pads connected by a wire , a differential mechanism for the orientation speed to speed 1/ 2 . Antenna rotates , a current flows to each lower brush , through a differential on the turntable one or two contact pieces circuit flow from the corresponding upper brush in order to ensure between the fixed part and the rotating part of the circuit is always on . fiber optic rotary joint sliding contact wear powder may cause a short circuit between the rings . Therefore, from the structure should ensure easy cleaning , usually with modular structure, so that on-site repair or replace components.
IF slip ring
Used to transmit the radar frequency ( tens of MHz ) signal and the energy slip ring assembly . The slip ring high frequency need to be shielded . Transmission signals below 12 MHz can use ordinary slip ring . A ring connected to the center conductor , an outer ring over cable as shielding ring ( Figure 2 IF slip ring ) . Transmission signals above 12 MHz usually shielded coaxial type slip ring . The cross section of the slip ring groove , is essentially rectangular coaxial conductors. IF there is a capacitive slip ring ( Figure 3 capacitive slip ring frequency ) , the center conductor is annular with an insulating pad supporting the shield , the rotating part and a gap between the fixed part , and do not touch , IF signal by capacitive coupling. A limited range of rotation of the antenna case can not rotary joints , but with the cable winding device .

Slip ring insulating properties
Insulation of electrical slip ring is a very important performance properties, it is a measure of the reliability of slip ring
is an important indicator, refers to the metal ring and metal rings,
metal ring and the spindle between the metal ring and wire between the
metal ring and the shell, between the wire and the wire insulation
strength. Mainly due to the insulating properties of insulation
material, the internal structure design. A good slip ring design on the
one hand should give full play to the advantage of material, on the
other hand should be avoided material on some of the flaws.
Metal ring and the insulating material between the metal ring, high-performance engineering plastics generally select or use an insulating film with a high-performance epoxy resin based insulating adhesive. Insulation sheet will generally use is to use some larger slip ring, like through-hole slip ring and some larger Customized Slip Rings, etc., using potting process is generally smaller cap slip ring and customized smaller slip ring. The dielectric strength of insulation adhesive gel formulation is mainly affected by the impact of technology and potting, insulating rubber generally uses about 60 percent of the epoxy resin, about 20 percent kaolin, about seven percent of phthalic acid dibutyl about five percent triethanolamine, and a few percent of other ingredients. Craft glue should avoid cracks in the curing process and bubbles, when the air humidity increases, the dielectric strength may be reduced.

Mercury slip ring applications and deficiencies
As the name implies , mercury slip rings, is the use of mercury as a conductive medium, the slip ring assembly . Mercury
is the only state at room temperature, liquid metal , precisely because
of this feature, as well as metallic conductivity. Just let this idea become a reality. Is
to mercury sealed within the slip ring , the fixed end and the rotating
end integrated, rotating it directly through the conductive transfer of
mercury to the current , the transmitted high accuracy, good stability,
no noise in the transmission signal .
Compared to other slip ring , since the medium is a fluid , creating a compact structure , small size features, this feature, tiny precision instruments in the field of special primary role of non- mercury slip ring perfectly. Because of the characteristics of mercury , when rotating slip ring wear , longer life expectancy than the average many times , in the need for frequent rotation conductive rotary joint , which is very appropriate. Since rotating parts without complicated mechanical structure makes the product more reliable and maintenance-free, no noise , no noise , high speed , low price signal is not distorted, contact resistance, pass more current .
Mercury slip ring wide range of applications ! From traditional industries to new industries , from the civilian sector to the military industries have to use mercury slip ring . Mercury as a material we all know , is a good conductor , compared with other materials such as copper , its conductivity is not bad, because mercury is liquid mercury as the medium of an electrical rotary joint , the main principle is the use of liquid mercury at room temperature while maintaining , and mercury can be conductive, and the resistance is small , the shape can be freely changed, so , and copper and other materials than on some occasions , more applicable , it can be said slip ring can be applied traditional occasions , mercury slip ring can be competent, but because mercury is highly toxic , and more expensive, so the market price to be higher than the slip ring a large portion of the mercury slip rings are generally used in relatively high-end devices ( such as a hospital CT) is more appropriate . Superconducting experimental use of mercury in there to achieve the conductivity of weak signal transmission, numbers and control current is very appropriate, more suitable for conventional slip ring incapable of areas, such as high- speed, low impedance, low interference and other occasions. Which applications are: automated packaging packaging machinery, packaging machinery hand , robots and other automated packaging .
Mercury slip ring advantages:Therefore, in its interior is not as complex as the mechanical slip ring structure . Volume ratio on the mechanical slip ring is much smaller , and this is one of its major strengths . When the rotation is mainly mercury internal molecular friction , and the friction between the seals , so that the mercury slip ring wear is very small , so its very long life , high speed , and without maintenance.
Mercury slip ring its shortcomings :
Since the thermal expansion coefficient of mercury , the mercury slip ring is not used at high temperatures , generally working temperature should not exceed 60 ° C , followed by its high precision mechanical sealing structure , one to let expensive, on the other hand to the working environment requirements efficiency, vibration environment must be shockproof , otherwise it will seriously affect the life.
