When it comes to terminals and single post connectors, PC pins 3-147070-0 are an essential element in modern electrical engineering. They are often used to connect electrical components in order to facilitate the transmission of power.

Designed to meet various industry and military specifications, these PC pins feature a 1.25mm total diameter that ensures excellent contact pressure, and up to 1.91 N of insertion force when mated. This ensures reliable connections, making these pins suitable for a wide range of applications, from high-speed critical connections in automobiles and medical devices, to advanced military applications, as well as various electrical components.

The design process of the 3-147070-0 PC pins involves careful calculations prior to assembly. Critical factors such as the minimum electrical contact space, the maximum contact pressure forces, and the length of the gold-plated area are all carefully engineered so that the pins can meet their performance requirements. The metal pins are typically composed of precious metals like tin, silver, nickel and copper, along with the gold plating. This combination provides good electrical resistance and corrosion resistance, making them a reliable contact solution.

The design of the PC pins is also very important, as the pins must fit into the corresponding connectors and keep a good electrical connection. The length, diameter and other dimensions vary according to different applications, and some pins also feature a raised collar that prevents the pins from slipping out of the mating connectors.

In terms of the working principle of the 3-147070-0 PC pins, the electrical contact between the two pins is established by compression contact. The contact resistance between the two pins is akin to pressure increase, caused by the contact force being introduced on one pin, which in turn causes the other pin to shift slightly and create contact.

The contact force is maintained in three ways: physically, surface area and springs. Physically, the pins\' contact will remain precisely in contact via the compression contact, meaning that the insertion force and contact pressure of the pins remain stable.

Surface area is another method of maintaining contact force. The area where the two pins meet increases over time as the contact force is maintained, ultimately increasing the contact force. Finally, spring-loaded pins can be used to maintain contact force and also allow for easy removal of pins, making them a preferred choice in certain applications.

In conclusion, PC pins 3-147070-0 are a reliable and versatile contact solution, suitable for a wide range of applications. By combining gold plating and metal composition, along with an efficient design process, they are extremely reliable and provide excellent contact pressures and insertion forces. Finally, the combination of physical contact, surface area and spring-loaded pins provides a reliable and efficient method of maintaining contact force.
