Backplane Connectors are a type of high-speed, high-density connections used in modern high-performance computing applications. Unlike other types of connectors, backplane connectors are designed to withstand high-speed signals, reduce crosstalk, prevent damage to components, and provide efficient connections between multiple devices. Two broad types of backplane connectors are Hard Metric and Standard backplane connectors.

Hard Metric Backplane Connectors

Hard Metric backplane connectors conform to the IEC or ISO standards for bus configurations. These connectors have different metric sizes, ranging from 2 to 10, and have rectangular contacts which can be either cut-off or blunt. The rectangular contacts are what provide the connection between the different devices. Hard Metric backplane connectors also have superior electrical performance, with a high level of crosstalk isolation and no signal distortion. Additionally, the larger sizes of Hard Metric backplane connectors are ideal for high-speed applications, such as PCIe, Serial ATA, and others.

Standard Backplane Connectors

Standard backplane connectors are most commonly used in the industry. These connectors come in a variety of sizes and configurations, and can be used in a wide range of applications. Standard backplane connectors are designed with simple pin configurations, allowing them to be used in multiple applications, such as computer boards, system control boards, and others. These connectors are compliant with the IEC or ISO standards, and have a high level of reliability and performance. Additionally, these connectors can be used in both free air and in conductor media.

Application Field and Working Principle

Backplane connectors are used in a variety of applications, such as computers, industrial control systems, communications systems, and medical devices. By providing reliable and high-performance connections, backplane connectors enable the reliable transmission of data and power between different components or devices.

The working principle of backplane connectors is based on the movement of electrons between the contacts. As the connector is mated, the contacts slide against each other to create a connection. The contact material creates an electrical connection between the contacts, allowing data to pass through the connection. Additionally, the contacts are protected by plastic or rubber seals, which provide insulation and protection from electrostatic interference.

In conclusion, Hard Metric and Standard backplane connectors are designed to provide reliable and high-performance connections between multiple devices. These connectors are designed to meet IEC or ISO standards, and are ideal for a wide range of applications, such as computers, industrial control systems, communications systems, and medical devices. By providing reliable connections, backplane connectors enable the transmission of data and power between different components or devices.
