Introduction to D-Shaped Connectors - Centronics

The D-Shaped connectors, also known as Centronics connectors, are a type of electrical connectors used to connect peripheral devices and computers. They are usually used to connect a peripheral device, such as a printer or scanner, to the computer by using a cable and the corresponding special port. There are several models of this type of Centronics connector, such as 71661-5080, and each has its own applications and working principles.

Applications of the 71661-5080

The 71661-5080 connector is usually used as a standard parallel connector for personal computers. It can send at least one-character data at a time in serial manner. This connector is ideal for unidirectional or bidirectional communication between computers, and it is also commonly found on older external storage devices and SCSI buses.

Working Principle of the 71661-5080

The 71661-5080 connector has a base which contains multiple pins, each surrounded by the same type of contact spring clips. These contact springs contain a wire which is connected to a resistor when the connector is inserted into the computer port, and they act as a kind of voltage regulator. When the electrical current flows through the pins of the 71661-5080 connector, it is regulated by the contact springs before it reaches the computer port. This principle of regulation is based on the fact that the contact springs are made of different types of materials with different electrical resistance values, and that the current flowing through them is affected by the difference in their respective resistance values. This regulation process ensures that the voltage and current supplied to the computer port is within the specified limits, and this helps prevent damage to the computer.

Conclusion

In conclusion, the 71661-5080 D-Shaped connector is a powerful and reliable connector for connecting peripheral devices and computers. It is ideal for unidirectional or bidirectional communication between computers, and its working principle is based on the contact springs surrounding the pins of the connector. The contact springs act as voltage regulators, ensuring that the input voltage is within the specified limits and preventing any damage to the computer.
