Backplane Connectors are electrical connectors used to interconnect two or more printed circuit boards, enabling data transfer between them. The contacts of the Backplane Connector, such as the 031-9134-001, are the most important component of this type of connectors, as they determine the necessary contact force, mechanical robustness and electrical performance of the connector. Therefore, understanding the application field and working principle of the 031-9134-001 contacts is crucial in order to use the connector effectively.

The 031-9134-001 contacts are designed for data transmission applications, suitable for the standard IEEE 1149.1 protocol. This protocol, also known as the Joint Test Action Group (JTAG), defines the physical requirements for the interconnection of all types of devices and system boards, and enables testing and monitoring of the circuitry. The 031-9134-001 contacts are fully compatible with this protocol, so they can be used in any application that requires it.

The 031-9134-001 contacts are made of high-quality copper and a gold flash plating, which ensures reliable electrical performance up to 9A and contact resistance of less than 5mΩ. The contact force is adjustable from 12N to 28N and the insulation resistance is greater than 1000MΩ, guaranteeing robustness and durability of the connector. The contact spring is covered with PBT plastic, offering further insulation for EMC immunity, and a wide temperature range of -55 to 125 °C.

Regarding the working principle of 031-9134-001 contacts, they are based on a pin-and-socket design, in which the spring-loaded socket is inserted into the mating pin. This design allows the connection of two boards without the need for solder, providing easy connection and disconnection when needed. In addition, the spring mechanism of the socket is designed to ensure that the contact is firmly and consistently engaged. Nevertheless, when multiple contacts are being used, all of them must be firmly pressed to ensure a secure connection.

In summary, the 031-9134-001 contacts are designed for applications using the Joint Test Action Group (JTAG) protocol and offer reliable electrical performance with adjustable contact force, low contact resistance and high insulation resistance. The contacts are based on a pin-and-socket design and require all of the contacts to be firmly pressed to ensure a secure connection. Thanks to the quality of the materials used, these contacts are suitable for a wide temperature range and provide EMC immunity.
