| Application | The D-subminiature or D-sub is a common type of electrical connector used particularly in computers. At the time of introduction they were some of the smaller connectors used on computer systems.Hard disk, Network scanner, Monitor, Digi-camera, Telecamera, Packet-routing, SDXC, Memory card, nand flash, CCD, SSD, Keyboard, Printer, Invigilator, flash drive and cable ASSY. | |||
A D-sub contains two or more parallel rows of pins or sockets usually surrounded by a D-shaped metal shield that provides mechanical support, some screening against electromagnetic interference, and ensures correct orientation. The part containing pin contacts is called the male connector or plug, while that containing socket contacts is called the female connector or socket. The socket's shield fits tightly inside the plug's shield. The shields are connected to the overall screens of the cables (when screened cables are used). This creates an electrically continuous screen covering the whole cable and connector system.
D-subminiature connectors were invented by ITT Cannon, part of ITT Corporation, in 1952.[1] Cannon's part-numbering system uses a D as the prefix for the whole series, followed by a letter denoting the shell size (A=15 pin, B=25 pin, C=37 pin, D=50 pin, E=9 pin), followed by the actual number of pins, followed by the gender (P=plug, S=socket).[2] For example, DB25 denotes a D-sub with a 25 position shell size and a 25 position contact configuration. The contacts in these connectors are spaced approximately 0.109 inches (2.77 mm) apart with the rows spaced 0.112 inches (2.84 mm) apart.[3] (To be precise, the horizontal contact spacing is 326/3000 = 108/1000 = 0.1086 inch per row, with the second row offset by half that amount.)
Cannon also produced "hybrid" D-subs with larger positions in place of some of the normal pin positions that could be used for either high-current, high-voltage, or co-axial inserts. The DB13W3 variant was commonly used for high-performance video connections; this variant provided 10 regular (20) pins plus three coaxial contacts for the red, green, and blue video signals. Hybrid D-subs are currently being manufactured in a broad range of configurations by other companies, including Amphenol, Conec, Teledyne Reynolds, Assmann Electronics, Norcomp, Cinch, 3M, and Tyco. Variations include current ratings up to 40A, operating voltages as high as 13, 500V, and waterproof variants that are certified to IP67 standards.
In the photograph below, the connector on the left is a 9-pin male (DE-9M) connector plug, and the one on the right is a 25-pin female (DB-25F) socket. The hexagonal pillars at either end of each connector have a threaded stud (not visible) that passes through flanges on the connector, fastening it to the metal panel. They also have a threaded hole that receives the jackscrews on the cable shell, to hold the plug and socket together.
