100746-1 Application Field and Working Principle

100746-1 backplane connectors are interchangeable, rectangular connectors that feature the same height and width with different numbers of contacts, allowing for simplified migration of connection type from one application to another. These connectors are commonly available in two to twenty-five row configurations, and have a nominal contact current rating of 3 Amps. The contact technology of these connectors is based on a normalizing floating contact system, and a positive locking system is used to ensure proper mating and secure connection.

100746-1 connectors feature a single piece housing comprised of an insulated material, such as thermoplastic elastomer, while a negative retention lock is provided at each end for secure mating. Each contact in the connector includes a mating and insulation displacement contact terminal, which is located between two insulation barriers. The housing also includes a strain relief feature which serves to secure the wire insulation jacket from being removed when the contacts are open.

When engaging the contacts of the backplane connector, two different forces are applied - a compression force applied at the contact termination, and a preload force which is applied at the contact contact through the keeping elements. The compression force is designed to reduce the contact resistance of the contacts, while the preload force ensures that the contacts remain in contact with the mating elements at all times. The preload force is determined by the design and material properties of the contact carrier.

These backplane connectors are designed to be used in applications such as computer systems, wireless base stations, routers, switches, hubs, control systems, and similar devices. The features and design of these connectors make them suitable for use in high speed applications, and they have proven to be very reliable throughout their design life. By providing a secure and reliable connection, the 100746-1 backplane connector offers a cost-effective solution for applications needing longterm reliability.
