Backplane Connectors - Contacts

Backplane connectors are widely used in communications, computing, and other systems for connecting circuit boards together. An important component of backplane connectors is the contact, which is the part that actually makes the electrical connection between two boards. 1857417-2 is one of the more popular contact types, and it is used in a wide range of applications. This article will discuss the application field and working principle of this type of contact.

The 1857417-2 type of contact is used in a variety of backplane connector designs. It is usually employed in high-speed systems, as it offers very reliable performance. This type of contact is used in both linear and flip-chip applications, and is suitable for a variety of bus speeds. It also has a low insertion force and a self-lubricating design, making it easier to install and maintain.

The 1857417-2 contact is a single-piece, male-type connector contact with a needle nose terminal shape. The contact has a 0.040 inch diameter, and a length of 0.165 inches. It is made of a phosphor bronze material and has a gold plating, making it suitable for a variety of applications. The contact is designed for use in a standard backplane circuit board connector, and is compatible with the following connector sizes: 0.635, 0.8170, and 0.9845 inch pitch.

The application field of the 1857417-2 contact is mainly for high-speed data transmission systems such as 10Gb/s Ethernet and PCI Express systems. Its low insertion force and reliable performance make it ideal for these applications. It is also one of the most reliable contact types and can handle up to 4,000 mating cycles.

The working principle of the 1857417-2 contact is relatively straightforward. When installed in a backplane connector, the contact engages when two backplane boards are pushed together. As the current flows through the contact, the contact provides an electrical connection between the two boards. This connection is maintained until the boards are separated.

The 1857417-2 contact is highly reliable and is suitable for a variety of application fields. It is designed to be used in high-speed backplane connectors, and its low insertion force and self-lubricating design make it easier to install and maintain. Furthermore, its gold plating and phosphor bronze material make it robust and able to handle up to 4,000 mating cycles. All of these features make the 1857417-2 a valuable contact type for backplane connectors.
