Backplane connectors provide a high-speed connection between boards for applications that require the transfer of large quantities of data. The 91570-104 is one such connector that is commonly used in backplane and system-level applications. It offers performance, reliability, and space efficiency. In this article, we will discuss the 91570-104\'s application field and working principle.

Application Field

The 91570-104/E series backplane connector is designed to provide connection for RJ45 Type-A modular jacks and can be used in external box-to-external box applications. Typical applications include industrial control, automotive control, army control systems, aerospace electronics, telecommunications and data communications, medical and instrumentation, and other industrial computer-related applications. The 91570-104 is well-suited to applications that require a secure data transmission and a reliable connection between boards. It meets multiple requirements from various industries and is an ideal choice for mission-critical applications.

Working Principle

The 91570-104/E series consists of a modular jack, a rear connector, and an optional customized strain relief. The modular jack has two components — the mating contacts and the Ethernet port. The mating contacts are made from brass alloy and are designed to give a tight connection between the modular jack and the rear connector. The modular jack has a specific shape and size that provides the reliable contact between the modular jack contacts and the rear connector contact. The design of the modular jack ensures that the contact between the two components remains secure even after the mating operation.

The rear connector is composed of two components: the terminal contacts and the printed circuit board. The terminal contacts are made from beryllium copper and are designed to provide a secure and reliable connection between the connector and the printed circuit board. The printed board can also be designed to enable a snap-in mechanism for easier installation. The snap-in feature ensures that the connector and the printed board are securely connected during the mating operation.

The optional customized strain relief helps provide a secure and reliable connection and is designed to withstand high-vibration environments. The strain relief also helps to reduce the chance of accidental disconnection due to excessive vibration caused by external forces. This feature is especially beneficial for those applications that require a highly reliable connection.

The 91570-104 is designed to reduce power, data, and signal losses and offers improved performance for applications that require the transfer of large quantities of data. It is an excellent choice for industrial control, automotive control, army control systems, aerospace electronics, telecommunications and data communications, medical and instrumentation, and other industrial computer-related applications.
