D-Sub, D-Shaped Connectors - Backshells, Hoods, is a type of electrical connector with various number of pins from 3-2198618-7, ranging from 9 up to 150. It is used in a wide range of applications requiring the fast and cost-effective connection of digital, analogue, coaxial, or fibre optic signals.

These type of connectors offer a great versatility of connections due to its wide variety of contact positions and pin/socket configurations possibilities. It is also cost-effective way for customers to signal and power distribution anywhere in an application. Along with electrical connection, they are also used for EMI and strain reliefs depending on the specific application field.

The main application field of the 3-2198618-7 would be for the securing of wires and cables in industrial automation, radiography, automotive, the medical industry as well as military and aerospace industry. The parts that make up the whole connector are the connector, the hood, and the nut. The connector and hood together form the shell. The hood, nut, and connector provide EMI (Electromagnetic Interference) and strain reliefs protection for the wiring.

The working principle of the 3-2198618-7 is relatively complex. First, each pin or socket contact is connected to the male connector’s front section via an interior cable. Second, the nut and the hood are used to secure the male connector to its female counterpart. Third, when the nut and hood are in place, they will compress the guide mechanism of the female connector against the front section of the male connector, thus providing for an electrical connection.

Additionally, a gasket is used to fill the gap between the female connector’s guide slot and the male connector’s front section, which prevents moisture and dust from entering the connector. Finally, when fully engaged, the pocket tension relief (PTR) allows the male and female contact to stay firmly fitted together and prevents any loosening over time.

In summary, the 3-2198618-7 D-Sub, D-Shaped Connectors - Backshells, Hoods are most commonly used for securing wires and cables in a wide range of applications. It is a cost-effective and versatile solution for digital, analogue, coaxial, or fibre optic signal connection. The components used for assembly are the connector, hood, and nut upon which the working principle is based and finally, the PTR ensures the two remain firmly connected together.
