Role of connector contact lubricants

For example, no matter which industry, electrical contact lubricants are used to improve the performance and reliability of electrical contacts and connectors. Invented in 1941 by the founders of Electrolube to improve the reliability of electrical performance and volume control, the use of contact lubricants has spread widely across multiple industries and has been a key factor affecting the stable performance of electrical equipment components for decades. Contact lubricants are specially manufactured greases and oils used to reduce friction and wear and improve the electrical characteristics of current-carrying metal interfaces, such as metal connectors on switches and connectors. Because the metal interface is completely flat and not smooth, when applied to surfaces such as thin films, it improves contact and electrical properties by filling all surface defects, reduces hot spots, burrs and arcs, and extends contact life.

The contact lubricant fills the air gap between the contacts, greatly increasing the effective surface area, preventing arc discharge and associated temperature rise and oxide formation. Additionally, provides a barrier to airborne pollution, promotes soft movement and reduces the effects of friction. Furthermore, the typical use of contact lubricants can also improve "feel" characteristics, such as improving the movement quality of a switch or simple plastic-plastic contact. Prevents electrical system failure, improves electrical transfer and reliability of contacts, contact lubricant fills all gaps, reduces resistance and thus increases contact surface area. Technology has spread to more important safety jobs inside vehicles, and the increase in electronic components has led to car recalls, so it is imperative that this important safety connection be maintained correctly. In other cases, this application may require contact lubricants with specific consistency and good electrical properties. There is a choice of "stimulating" or "hard" grease, which remains in place during mechanical operation of the switch. In this case, cone hole penetration or lubricant wear testing at different temperatures helps with product selection. Conversely, in applications with low contact forces, very soft oils or contact oils may be required. In this case, it is necessary to test the mechanical action of the switch using a range of lubricants to determine suitability. Therefore, all electrical requirements, material compatibility and environmental impacts must be considered when selecting the right lubricant. With the development of electronic applications, the improvement of electrical performance of vehicle switches and connectors mainly focused on low-voltage switches, moving to more important applications. With the changes in electric vehicles, more challenges are presented, including more electrical connections and, most notably, higher voltages being delivered around the vehicle. According to the experience of heavy-duty pressure switches, electroplating, relays and other industries, we provide a variety of products to meet the demanding requirements of the electric vehicle market.
