Introduction to Backplane Connectors - Contacts

Backplane connectors provide a physical interface between two printed circuit boards in order to enable signals and power to be passed between them. The most common type of backplane connector is a contact-based system which utilizes either male or female pins to connect the two boards together.The 1857181-3 contact is one of the most widely used backplane connectors, due to its ability to provide a reliable and secure connection that can perform in a wide range of applications. The 1857181-3 contact is typically composed of a plastic infill surrounded by a ferrous metal body, and is available in a variety of contact types, connection styles, and contact configuration options.

Applications for 1857181-3 Contacts

The 1857181-3 contact is typically used in applications requiring high reliability and long-term signal integrity. This makes them ideal for applications such as data centers, telecommunications equipment, and servers, as they can provide a highly reliable connection against a variety of environmental conditions.Beyond providing reliable connections, the 1857181-3 contact is also well-suited for applications where contact density plays a major role. This contact type can provide higher densities due to its ability to carry multiple contacts in a single housing. This makes it ideal for medical and aerospace applications, where contact location and density are often critical factors.

Working Principle of 1857181-3 Contacts

The 1857181-3 contact is designed to provide a reliable connection between two printed circuit boards that can withstand a wide range of environmental conditions. In order to achieve this, the contact utilizes a simple design principle.The contact consists of a plastic infill that is surrounded by a ferrous metal body. The plastic infill acts as an electrical bridge between the two contact points on the circuit boards, and also contributes to the contact’s ability to withstand high levels of temperature and pressure. The ferrous body is designed to hold the plastic infill in place and provide electrical shielding, which prevents the contact from emitting electromagnetic radiation.The contact utilizes a spring-loaded mechanism to ensure that it provides a secure and reliable connection. This spring-loaded mechanism ensures that when the contact is mated, the two contact points are pressed together with a consistent force, regardless of the environmental conditions. This ensures that the contact remains in place and is able to maintain the connection over long periods of time.

Conclusion

The 1857181-3 contact is a reliable and secure backplane connector that is ideal for a wide range of applications. It utilizes a simple design principle, utilizing a plastic infill surrounded by a ferrous body, which helps to protect it from environmental conditions and ensure a secure connection. This makes it an excellent choice for applications where contact density and reliability are paramount, such as in medical and aerospace applications.
