A band finger is a specially shaped elastic connecting component that has been in practical use for over 50 years, making it an excellent choice for high current, high insertion/extraction life, and harsh environment applications. Below is some detailed information about the band finger:
Application Areas: The strap contacts are suitable for various electrical connections in high-voltage equipment, widely used in high-voltage switches, circuit breakers, sleeves, and busbars. In the power transmission and distribution industry, electrical connections must possess safety, efficiency, and stability. The strap contacts ensure excellent electrical connection performance with their low heat generation power, low contact resistance, and stable, uniform contact force.
Technical Features: The strap contact technology, also known as MULTILAM technology, establishes parallel contact points between two surfaces by providing certain contact force, capable of breaking down contamination layers and achieving effective electrical connections. Each contact leaf forms an independent elastic load-carrying bridge, significantly reducing the overall contact resistance.
Material and Manufacturing: The watch band contacts can be made from high elasticity beryllium copper alloy or elastic and conductive alloy copper thin plates. These materials are manufactured through a strictly controlled process, offering excellent conductivity and high elasticity, suitable for various circuit breakers, cable accessories, busbars, and high current industrial connectors.
Design Features: The strap's touch point is small in size, with a simple structure, multiple touch points, and strong current conduction capability. It does not require a tight spring, ensuring stable contact pressure and fatigue resistance. Installation is convenient, and the service life is long. It can be customized for single-point, double-point, or strong-conduction embedded contact as needed, to accommodate different rated currents and dynamic thermal stability currents.
Application Range: The belt contact fingers are widely used in intermediate sliding and dynamic-stationary contacts of switching equipment. Due to their small radial dimensions, they are particularly suitable for compact radial size environments. Belt contact fingers also find extensive applications in data transmission, fiber optics, coaxial applications, and photovoltaics.
Overall, the belt connector is a high-performance, simple-structured electrical connection component that meets stringent operational requirements in various conditions, providing robust assurance of safety, efficiency, and stability for the power transmission and distribution industry.
