Rectangular connectors, such as the 179841-1 header, are among the most common types of electrical connectors. These devices usually consist of either a header, male pin, or terminal block. The most common type are "headers" which are a combination of male and female contacts which mate with each other. The 179841-1 header is a hybrid header that combines a male header pin and a female socketed contact.

Application and Working Principle

The 179841-1 header is designed for high density board-to-board connectivity and is often used in applications such as consumer electronics, industrial automation, communications, lighting, and medical devices. Its operating principle is based on the electrical connection of the male header pins, which are usually found in a row soldered to a printed circuit board (PCB), with the female socketed contact. Contact is made when the female contact connects to a corresponding header pin. A secure connection is ensured through a friction lock that snaps the two components together by pressing the contact onto the header pin.

The header pin density can vary depending on the application requirements, but is typically between 1 and 7 pins. Larger pin densities are also available, up to a maximum of 50 pins. The number of pins and receptacles depends on the application and may vary between manufacturers. The contact is usually a gold-plated metal terminal, which is designed to provide a good electrical connection between the two components.

Advantages

The 179841-1 header offers a number of advantages over other types of connectors. These include a small size, allowing for a wide range of connection options, and a low cost which make it an ideal choice for many applications. The header also has a unique friction lock design which ensures a secure connection even under shock and vibration conditions. The terminals are rated to carry a higher current than other types of connectors, and the header is easy to assemble and disassemble.

The 179841-1 header is also highly reliable, as the metal terminals are designed to ensure a good electrical connection. The design of the header allows for a wide range of applications, including high temperature and high voltage applications. The header has a low profile, which reduces installation space and cost. Additionally, the terminals are designed with a plated finish which provides corrosion resistance and enhances electrical conductivity.

Conclusion

The 179841-1 header is an extremely versatile rectangular connector suitable for a wide range of applications. Its small size and low cost make it an ideal choice for many applications. Its unique friction lock design ensures a secure connection, and its terminals are rated for a higher current than other types of connectors. The header is highly reliable, and its plated finish enhances electrical conductivity and provides corrosion resistance.
