ELFB1813G Application Field and Working Principle

The ELFB1813G terminal block from HAR WIN is a cable-to-board power connector in the digital-signal conductor segment. It is an innovative termination method for power connections serving as an alternative to common soldering methods. The ELFB1813G terminal block can be used in various applications for relays, power supplies, and other industrial machinery. It provides safe, reliable, and efficient transmission of power for critical applications.

The ELFB1813G is composed of two sections: base and top section. The base section is typically wired to the cable connection and is capable of carrying up to 12-14 amps. It incorporates a secure screw-in design to offer a vibration-proof connection, making it very reliable even in harsh environments. The top section is designed to connect to a printed circuit board, which carries up to 2.2 amps. The top section is attached to the base via a locking lever.

The ELFB1813G terminal block design incorporates a double insulation barrier: high-temperature thermoplastic insulation material for the top section, and a void-free insulated epoxy infused cable sleeve for the base section. This design improves insulation and provides shock and vibration resistance. The combination of insulation, plus a pin-pin connection (both housing and pins), reduce resistance to near zero. At the same time, the combination of insulation and pin-pin connection ensures continuity under harsh conditions.

Overall, the ELFB1813G terminal block offers a broad range of features that directly improve the performance of industrial machines. Its unique design ensures safe, reliable, and efficient power transmission to areas that were previously difficult to access. The ELFB1813G is designed for safety and can be used in many applications, in signs, LED lighting, and medical equipment.

Working Principle

The ELFB1813G terminal block incorporates a patented double insulation barrier design that ensures safe and reliable power transmission. When the connector is closed, the plastic housing of the base section is pushed into contact with the printed circuit board connection. Simultaneously, the pin and socket are wedged together, creating a mechanical and electrical connection. This establishes a secure connection between the cable and the printed circuit board.

The base section also incorporates a secure, screw-in design with a secure snap-on locking lever. This design provides an improved vibration-proof connection, even in harsh conditions. This makes the ELFB1813G ideal for use in industrial machinery and electrical equipment.

The ELFB1813G is designed for easy installation. The terminal block has a broad range of features to ensure it can be installed in almost any environment with minimal effort. It is also available with various pin configurations to ensure maximum flexibility.
