2-176793-8

D-Sub, D-Shaped Connectors - Backshells, Hoods

Application Field and Working Principle

The 2-176793-8 connectors, otherwise known as D-subminiature or D-sub connectors, are typically used for applications involving signal and data transmission. These connectors feature an array of pins or sockets surrounded by a D-shaped metal shield. The shield can be made of steel, brass or aluminum, depending on the application. Commonly, the shell is used to provide grounding, EMI/RFI shielding, and secure connection of the pins/sockets in the mating process. As a vital part of a typical D-sub assembly, the shell or hood provides physical strain relief for the associated cables. The application field of the 2-176793-8 is wide, from industrial automation, medical field to aerospace and defense.

A D-sub connector typically consists of a metal backshell, contacts, and insulating plastic body. The D-shaped hood, which is the most conspicuous part of a D-sub connector, serves many purposes such as shielding the connector from electrical interference and protecting the wiring from damage. Inside the hood, the contacts are typically arranged in two parallel rows and connected with a printed circuit board. The backshell is the group of components which connect directly to the cable and make up the entire connector assembly. It also provides additional stability and strain relief for the connection.

The working principle of the 2-176793-8 is based on simple snap-in connections. The contact pins, which are typically made of conductive metal such as copper, are placed into the corresponding slots in the hood. The contacts are surrounded by the insulating plastic body and the metal shield of the hood, which gives the assembly enhanced protection against environmental factors. When the contact pins of the connector are inserted into the mating part, they create an electrical connection. This connection creates a link between the devices and allows data and signals to be transmitted within the system.

The 2-176793-8 D-sub connectors offer superior electrical and mechanical performance. It is durable enough to stand up Wear and tear, while still providing reliable connectivity. It has a wide range of application in many industries due to its efficient data transmission characteristics. It is also known to be reliable, cost-effective, and easy to install, making it an ideal choice for industrial automation, medical, aerospace and defense applications.
