Backplane Connectors - Hard Metric, Standard - 646573-1 Application Field and Working Principle

Backplane connectors are used in a wide range of electronic equipment and are essential components in the design of electronic systems. There are two main types of backplane connectors, Hard Metric (HM) and Standard. The 646573-1 is a type of standard backplane connector specifically designed for high speed digital applications and provides a robust solution for your PCB interconnection needs. In this article, we will discuss the application field and working principle of the 646573-1 backplane connector.

Application Field and Operating Environment

The 646573-1 connector is designed for use in a wide range of mission and mission-critical applications including automotive electronics, industrial control, medical devices, telecommunications, and military applications. It is also suitable for applications using traditional components or Optical Interconnect Technology (OIT). It can provide signal integrity and reliability even in harsh operating conditions such as extreme temperatures, shock, and vibration environments. With its increased insulation, robustness, and cost effectiveness, the 646573-1 standard backplane connector is ideal for use in high-performance digital applications.

Construction and Features

The 646573-1 connector is constructed with high-performance materials. The pin and socket contacts consist of aluminum alloy and tin-plated copper with a durable gold contact plating. The contact area has a large surface area for better current carrying capacity and minimal contact resistance. The molded connector housing is constructed with a durable material like thermoplastic and black polycarbonate. It features high dimensional stability and a terminal mountable backplane allowing easy maintenance and installation.

The 646573-1 is designed to accommodate low signal-to-noise requirements and its improved contact plunger design increases contact reliability. It also provides superior signal shielding and isolation with its aluminum housing and individual sub-shielding. The contact pads use a common interface size which allows compatibility with most Printed Circuit Board (PCB) footprint requirements. The 646573-1 also features a low mating force, making it easy to use in high speed applications, and its robust internal design ensures reliable high-speed data transfer.

Working Principle

The 646573-1 operates through the use of a machined proboscis contact. It has one contact pad and one pin for each contact. The pins feature high lubricity and a low contact force, enabling easy mating and superior performance. A metal shielding element is inserted between the contact and the contact pad to provide immunity from external interference. The connector also utilizes a special harness that provides a secure mechanical bond between the contact and the housing. The harness also reduces ground loop noise.

Once the connection is made, a spring-loaded contact system ensures that the mating force is distributed evenly and securely. A compression force is provided by a latch mechanism to ensure a reliable connection. The latch locks the mating parts and ensures that the connection is maintained. The connector is compatible with board-level components and can carry both differential and single-ended signals.

Conclusion

The 646573-1 is a highly reliable standard backplane connector that is specifically designed for high-speed digital applications. It provides superior signal and power transmissions performance with its improved contact plunger design and increased insulation. The connector is robust and cost-effective and can accommodate a wide range of mission and mission-critical applications. With its easy installation and high-performance interface, the 646573-1 standard backplane connector is an ideal solution for your PCB interconnection needs.
