A band finger is a specially shaped elastic connecting component that has been in practical use for over 50 years, becoming the choice for high current, high insertion/extraction life, and harsh operating conditions. Below is some detailed information about band fingers:
Application Fields: Belt contact fingers 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 belt contact fingers ensure excellent electrical connection performance with their low heat generation power, low contact resistance, and stable and uniform contact force.
Technical Features: The band touch technology, also known as MULTILAM technology, establishes parallel contact points between two surfaces by applying a certain degree of contact force, which can break down the contamination layer and achieve an effective electrical connection. Each contact leaf forms an independent elastic load-carrying bridge, thereby significantly reducing the overall contact resistance.
Material and Manufacturing: The watch band can be made from high elasticity beryllium copper alloy or alloy copper thin plate with excellent elasticity and conductivity. These materials are manufactured through strictly controlled processes, offering good conductivity and high elasticity, suitable for various circuit breakers, cable accessories, busbars, and high current industrial connectors.
Design Features: The strap features a compact touch point size, simple structure, multiple touch points, strong current conduction, and does not require a tight spring. It offers stable contact pressure, fatigue resistance, easy installation, and a long service life. It can be customized for single-point, double-point, or strong-conduction embedded contact as needed, to carry different rated currents and dynamic thermal stable currents.
Application Range: The band finger is widely used in intermediate sliding and dynamic-stationary contacts of switchgear. Due to the small radial size of the band finger slot, it is particularly suitable for compact radial size environments. The band finger also finds extensive applications in data transmission, fiber optics, coaxial applications, and photovoltaics.
Overall, the watch band connector is a high-performance, simple-structured electrical connection component that can meet various stringent working conditions, providing a strong guarantee for the safety, efficiency, and stability of the power transmission and distribution industry.
