Mercury slip ring is also called rotary connector,Rotary joint, mercury contact, conductive joint, conductive ring, collector ring, collector ring, etc.Different from the traditional carbon brush slip ring, liquid mercury is used as the conductive medium to integrate the fixed end with the rotating end, no longerneedCarbon brushes.
The biggest difference from the traditional carbon brush slip ring is that it mainly uses liquid mercury as the conductive medium and integrates the fixed end with the rotating end. When rotating, it does not need to use carbon brushes for conductive transmission, but directly uses mercury for conductive transmission.
The slip ring mainly refers to the connection mode between two parts. The electric brush is used as a precision part for signal transmission between the active part and the fixed part. It realizes the transmission of current, power and temperature signals between two relative rotating parts. The mercury slip ring mainly refers toTransmission mediumSlip ring mainly made of mercury.It is very different from the traditional collector ring. Its advantages are reliable use, high precision, high support for high loop and high current.

Compared with other slip rings, because the medium is fluid, it has the characteristics of compact structure and small size, which plays a major role in the field of special micro precision instruments.Due to the characteristics of mercury, the slip ring has no wear when rotating, and its service life is many times longer than that of ordinary ones. It is very suitable for conductive rotary joints that need frequent rotation.Because there is no complex physical and mechanical structure in the rotating part, the product is more reliable and maintenance free, without noise, noise, high speed, low price, no distortion of signal, small contact resistance, and larger current transmission.Because of these characteristics, the advantages of mercury slip rings make their products very attractive and competitive.Although the price is expensive, it occupiesa space for one person。

For the mercury slip ring with small size and high precision, its installation and fixation is a very difficult problem. How to install it correctly and reasonably? First, fix the mercury slip ring on theRotation axisOne end of.The coaxiality with the rotating shaft will affect the service life of the slip ring.Secondly, both ends of the mercury slip ring can be rotated to fix either end.In addition, we must use the terminal provided with the slip ring to ensure the service life. Never directly weld the wire to the slip ring terminal.If you encounter problems in the specific installation process, you can contact the technical support or customer service representative of the mercury slip ring supplier to help you install and debug.
