Introduction to D-Shaped Connectors - Centronics

D-shaped connectors are a type of electrical connector designed to provide electrical connectivity between two electrical devices. Connectors of this type are often referred to as Centronics connectors, due to their popularity among desktop computer users for connecting peripherals, such as printers. Centronics connectors are characterized by their “D-shaped” housing, which is designed to fit snugly into corresponding ports on the equipment being connected.

5556622-2 Connector Application Field and Working Principle

The 5556622-2 is a Centronics connector designed for use with printers. It is a 25-pin, male-to-female connector commonly used to connect a printer to a computer. It is also commonly known as a Centronics connector, and its full name is “Centronics type II”. It was designed by the Centronics Corporation in 1976.

The 5556622-2 connector uses a two-piece, push-pull mating system to make the electrical connection. It has 25 pins arranged in three rows. The two rows on the left have eight pins each, and the row on the right has nine pins. The pins are 0.1 inches (2.5 mm) apart, and each pin has a diameter of 0.062 inches (1.57 mm). The connector also has two plastic locating pegs that fit into corresponding slots on the port. These pegs serve to keep the connector in place and prevent it from being accidentally disconnected.

When the connector is inserted into the port, pins on the connector contact corresponding pads on the port. The pins and pads are then connected by tension-mounting clips that mount to the case of the connector. The tension-mounting clips exert pressure on the pins and pads and create an electrical connection.

The 5556622-2 connector is a reliable and durable device, and it is designed to resist electrical noise and provide a secure connection. It is compatible with most popular printer models, and it is usually available in a variety of colors, including black, beige, and gray.

Conclusion

The 5556622-2 is a Centronics connector designed specifically for use with printers. It uses a two-piece, push-pull mating system to make the electrical connection and has 25 pins arranged in three rows. When inserted into the port, pins on the connector contact corresponding pads on the port and are connected by tension-mounting clips. The 5556622-2 is a reliable and durable device, and it is compatible with most popular printer models.
