5748678-3 Connectors, Interconnects

D-Shaped connectors and backshells, or “D-Subs”, are physical devices used to connect two wires together. They are typically used in the wiring harness for cars, boats, aerospace, and industrial applications. The components of a D-Sub connector system consist of an insulator block, a connector shell, a plug, and the adapters for the connector shell.

A D-Sub connector’s primary application is to provide connection between two electrical circuits or electrical components. It provides a secure physical connection between them and establishes an electrical circuit by applying a constant voltage or current. The connector can also be used to provide noise isolation between the two circuits, which is why it is preferred in high-noise environments.

The principle of the D-Sub connector is simple. The two conducting surfaces, usually pins or blades, are connected to the two wires and secured in place by a backshell. The backshell, which fits snugly over the wire, helps keep dirt and debris from entering or breaking the connection. The plug and the adapter for the connector are seated in the end of the backshell, creating a seal between the two. When both sides of the connector has been inserted, the voltage or current is carried through them to the opposite connector.

The D-Sub connector is commonly used in harsh and noisy environments. Its design ensures that it can withstand the rigors of these environments, such as vibration and temperature variations. Additionally, the connector is designed to be able to handle small amounts of water and dust without any damage to the connection. This makes it the perfect choice for applications where the environment is harsh or unpredictable.

The 5748678-3 is a particular type of D-Sub connector. It is designed to provide connection between one pair of electrical circuits or components, and features a 9-way single row, hollow-end design. This type of connector is typically used in cars, boats, aerospace, and industrial applications. The 5748678-3 is made from high-grade stainless steel and brass, which makes it highly durable. It is also capable of handling electrical currents up to 10 A.

Due to its design and rugged construction, the 5748678-3 is able to withstand extreme temperatures and environments. Its robust construction means that it can be used in various applications where harsh and noisy conditions are present. Additionally, its tight connection prevents dirt and water from entering the connector, making it suitable for use in harsh or unpredictable environments.
