D-shaped connectors are a type of Centronics-style connectors commonly used for connecting computer peripherals. The 554815-1 is a particular type of D-shaped connector and is widely used in many applications and products. This article will provide an overview of the 554815-1 application field, working principle, and related specifications.

The 554815-1 is mainly used in electronic products such as server, computer, and audio/video equipment that require small and highly reliable interconnections. It is most commonly used as a connection between the Drive-Bay and PCB-Board in the form of a Motherboard to Plug cable, thus providing a reliable mechanical and electrical connection between the two components. The typical mating Force and Unmating Force for the 554815-1 are 7N and 5N respectively.

The working principle of the 554815-1 is quite simple. It contains two electrical pins, each with a positive-contact conductive point that is connected to the PCB-Board with a metal shield. The other end of the metal shield, which is connected to the driven-bay, is also connected to the two electrical pins. When the mating-force is applied to the system, the metal shield ensures that the electrical pins get securely connected to both the drive-bay and the PCB-Board. This type of connection is known as a ‘Cold-swap’ connection, which eliminates the need to power off the system while connecting or disconnecting it from the drive-bay.

The 554815-1 is compliant with the IEC 60950 standard, and comes with a variety of accessories to ensure a secure connection such as a set of strain reliefs, a cable clamp, and a robust shell. The shell is made up of corrosion resistant material to ensure maximum durability, and it is also available in various colors to suit customer’s needs. The contacts in the 554815-1 are gold plated, and the entire assembly can operate at temperatures ranging from -25°C to 125°C.

In conclusion, the 554815-1 is a reliable and highly versatile D-shaped connector used for a variety of applications. It is compliant with IEC 60950 standards, and is highly durable due to its high-quality materials and construction. The 554815-1 is easy to use, and its ‘cold-swap’ connection eliminates the need to power off the system while connecting or disconnecting it from the drive-bay. It is available in various colors to suit customer’s needs, and the range of accessories ensures a secure and reliable connection every time.
