D-Sub Connectors

A D-sub connector, also known as a D-subminiature connector, is a type of electrical connector commonly used in computers. It was developed by the Deutsch company in the 1950s and was named after its inventor, Walter Deutsch. The D-sub is popular due to its small size and wide array of possible configurations. It is typically used for wiring between circuits and components, such as in laptop computers or controllers.

1-747944-6 Application Field and Working Principle

The 1-747944-6 D-sub connector is a type of PCB mount, low impedance D-subminiature connector. It is constructed using thermoplastic insulator material, which ensures reliable connection and excellent heat and vibration resistance. This type of D-sub connector is typically found in consumer electronics, automotive electronics, and industrial control applications.

The 1-747944-6 operates by having two male and two female contacts, each of which are joined by a common ground pin. When mated, the two contacts come in direct physical contact, ensuring an electrical connection. Operating temperature range for the 1-747944-6 is -25°C to +105°C (including temperature coefficient). It has an electrical current rating of 2A (RMS) and voltage rating of 250V (AC/DC).

The operating mechanism of the 1-747944-6 consists of a combination of a latch and slots. The latch holds the contacts steady and the slots prevent pins from slipping out. The contacts are held in place by spring tension and friction between the mating surfaces of the contacts. This allows the connection to be made and the contacts will remain secure under normal operating conditions.

The 1-747944-6 D-sub connector is also well-suited for use with shielded electrical cables and avoid EMI problems. This type of D-sub connectors is designed to prevent the emission of electromagnetic radiation and protect the circuits from ambient interference. This shielding helps ensure proper data transfer and minimizes errors in applications that require reliable communication, such as automotive electronics.

Overall, the 1-747944-6 D-sub connector is an ideal solution for a variety of electronic applications that require a compact, reliable, and shielded connection. It is highly reliable and compatible with a wide range of electrical cables and components, making it an excellent choice for application in consumer electronics, automotive electronics, and industrial control applications.
