The 73981-102LF is a specialized backplane connector that has recently become more popular for certain applications. It is an ideal choice for highly dense, high-speed, and high-performance circuit board connections. Because of its high-speed transmission performance, it is commonly used in a variety of applications, including servers, communication systems, and high-end router applications, among others. In this article, we will discuss the working principle of this connector and its application field.

Working Principle of 73981-102LF

The 73981-102LF backplane connector is designed to meet the demands of signal integrity, signal transmission speed, and molding pressure during the circuit board connections. It uses a two-contact construction system, which is divided into two parts: a two-piece socket contact and a two-piece plug contact. The two pieces of the contact are connected to the circuit board through four plated holes. The inner contact locking member is inserted between the two contacts, which ensures reliable electrical connection and control electro-mechanical reliability.

The two-piece socket contact is made up of a copper alloy housing and a spring contact that is designed to ensure a tight connection. The socket contact is inserted into the plated hole of the circuit board. When the plug contact is inserted, the two contact locking members are pushed and locked, which ensures a tight connection.

The two-piece plug contact is also made up of a copper alloy housing and a spring contact. The elastic contact provides the correct contact pressure and also ensures the secure connection with the socket contact. The contact locking member is a housing-mounted wire spring that is designed to ensure a secure connection between the plug contact and the socket contact. Therefore, the 73981-102LF backplane connector has a reliable electrical connection and control electro-mechanical reliability.
