170111003 - Backplane Connectors - Hard Metric, Standard

Backplane connectors are devices that link electrical and electronic components within a system. They exist to provide efficient, reliable and safe connections between the parts of a system, and also combat the data transmission losses associated with different components. Two of the most commonly used types of backplane connectors are the hard metric and the standard types.

Hard Metric

Hard metric backplane connectors are an older, legacy technology that is quickly being replaced by more advanced, high-speed designs. Hard metric connectors provide for high-speed, low-frequency data transfer, as well as basic power and grounding connections. These connectors contain a sheet-metal housing that is filled with parallel pins. This allows the pins to move freely and provide a secure electrical connection. The connection between the two components is secured by two plates that are moved towards each other to provide an exact mechanical connection. Most hard metric backplane connectors are designed to meet IEEE specifications, with a standard connector having 50 to 200 pins. The term “hard metric” comes from the stiffness of the mating connectors, which makes them less desirable for large applications or complex power and signal requirements.

Standard

Standard backplane connectors have a simpler design that is used more often in modern applications. As compared to hard metric connectors, standard backplane connectors provide for less data transmission losses since they are more secure. These connectors use metal or plastic pins, cups, grooves, and/or slots to secure the connection between two components. They are available in a variety of sizes and can have up to 500 pins. Standard connectors are typically used in applications that require multiple modules to be connected to the same system. They are better suited for high-frequency data transfers due to their higher quality signal and secure connection. They are also more cost-effective than hard metric connectors, making them a popular choice for applications ranging from consumer electronics to industrial equipment.

Working Principle

The working principle of backplane connectors is similar for both the hard metric and standard types. Both use pins or sockets to transfer power and/or data between two components. The pins or sockets are inserted into the connecting parts of the connector and secured with a secure locking mechanism. This secure locking mechanism ensures that the connection is strong and that there are no signal or power losses due to the vibration or movement of the components. Once the connection is secured, the electrical conductors in the pins or sockets transfer the power and signals between the two components. The signals are transferred at high frequency, which helps reduce data transmission losses. In addition, the connector can also provide current, shielding, and grounding.

Application Field

Backplane connectors are used in a variety of applications, with the primary purpose being to reduce data transmission losses and secure the connection between two components. Hard metric connectors are usually used in legacy applications that require low-frequency data transfers, while standard connectors are more suited for higher-frequency data transfers and are found in consumer electronics as well as industrial equipment. Backplane connectors are also commonly used in the telecommunications, aviation, automotive, and medical industries as a cost-effective way to provide secure and reliable connections between different components. They are also used to create test systems, prototypes, and monitor systems, as well as for multi-media, networking, and other data sensitive applications. In conclusion, backplane connectors play an important role in the functionality of various systems. Both hard metric and standard connectors offer reliable and secure connections that are integral to their respective applications. Understanding the application fields and working principles of these connectors will help ensure that the correct type of connector is used for each application.
