A D-sub connector is a sort of contact/connector typically found in electronics and communication systems. It is composed of a D Shaped metal band and many more parallel rows of pin contacts, commonly referred to as "male" or "socket contacts called female." The dimensions, materials, current ratings, lengths, and resistance of D-sub connector contacts might vary. The crimp contact is the most common kind of connection. A stripped wire end is inserted into the cavity at the back of the contact to assemble it. A crimp tool is then used to squeeze the cavity while grasping the contact with the wire.
Types of D Sub contact
Wires can be connected to D-sub connector contacts using some distinct techniques.
Solder Bucket Contacts
Solder bucket contacts carry a cavity into which the stripped wire is placed and manually soldered.
Insulation Displacement Contacts
Insulation displacement contacts ensure a ribbon cable is reinforced with keen tines on the back side of the connection; this works on the insulation of the whole wires at the same time. This is so quick in the sense of assembly, whether carried out manually or mechanically.
Crimp Contacts
Crimp contacts are put together by placing a stripped wire end into a hollow in the back of the contact, squeezing the cavity with a crimp tool to make the cavity securely grab the wire at various locations, and then connecting the two parts. After being put into the connection, the crimped contact is locked into place
PCB Pins
PCB pins are not soldered to a wire but rather directly to a printed circuit board. Through-hole plated (THP) board-type pins have historically been utilized (print). Still, gull-wing surface mount (SMD) connections are becoming more popular, even though the latter typically have solder pad contact issues when subjected to mechanical stress.
