What is D-sub connector backshell or hood?

It is made of thermoplastic or metal with 2 thumbs screw on the sides and it can also protect the cable from strain and, for the metal hood, EMI/RFI to enhance the performance and stability of the connections. The front and rear parts of the housing can be assembled with the D-sub connector by nuts and screw. The strain relief at the back of the hood relieves excessive force from the hood assembly that can possibly damage the cable. Both waterproof and non-waterproof hoods are available. The rubber ring on the hood seals the connector after the screws are tighten to the panel and avoid water leakage. Generally, the metal housing is more durable than the plastic housing, especially for the applications that requires re-assembly of the connector hood.
