Slip rings, as a kind of rotating conductive parts that have emerged since the beginning of the second industrial revolution, have now reached perfection in the industry. How have professional slip ring manufacturers such as JINPAT developed their research and development? For a long time, JINPAT Electronics has insisted on investing a minimum of 3% of its annual operating income in R&D. By the end of 2022, JINPAT Electronics has obtained 62 national patent authorisations related to slip rings, of which 6 are invention patents. Relying on technology accumulation driven by long-term investment in R&D, JINPAT Electronics has made great achievements in the production of slip rings for automation equipment, slip rings for construction machinery, slip rings for consumer electronics, slip rings for medical equipment and precision instruments, slip rings for ultra-high voltage megawatt class electric motors. rings, military photovoltaic turret slip rings, high-frequency integrated slip rings, high-frequency integrated slip rings, and high-frequency integrated contact rings.

In fact, the most important part of the slip ring is the friction pair. In an electrical slip ring, there is a wire brush friction pair and a carbon brush friction pair. The ratio of the different materials of the friction pair affects the electrical performance (signal transmission) and service life of the electrical slip ring, as well as other decisive factors. Currently, the test bench of JINPAT’s Electronic Experiment Centre and Quality Control Department can simultaneously handle up to 400 units of slip rings with different functions to test the service life or electrical performance. The scale of this test equipment is the largest in the industry. Slip ring friction couple experiments test materials, so high and low temperature and salt aerosol resistance tests are mainly focused on some special materials. Of course, the slip rings that require these capabilities have a relatively special design, so in many cases JINPAT improves the structure of the product and also checks the performance and service life of the slip ring on the test bench.
