D-Sub connectors are a type of electrical connector that is commonly used in computer and telecommunications applications. They are often used to connect cables between components, such as a computer\'s motherboard and an expansion card, or between two types of cable, such as serial or parallel. The "D-Sub" designation stands for "double-shielded" because it has two shield layers-an inner foil layer and an outer braid layer-which provide extra protection from external electrical interference.The most popular D-Sub connector is the DE-09, or DB-9, which has 9 pins and is commonly used for RS-232 (serial) connections. It is also available in larger sizes with up to 37 pins. D-Sub connectors can be either male (plug) or female (receptacle). The male connector has pins that protrude from its body, while the female connector has holes or sockets into which pins will fit.The 172-015-112-021 D-Sub Connector is a 15-pin variant in a male configuration, typically used for VGA video and game console applications. The connector has two rows of 7 pins spaced 0.200 inches apart and an additional row of 1 pin spaced 0.100 inches below the two rows of 7 pins. The pins are configured as three ground pins, three orientation pins, and nine signal pins.The most common application for the 172-015-112-021 D-Sub Connector is in connecting a VGA monitor to a PC. In this application, the VGA connector is attached to the monitor and the D-Sub Connector is attached to the PC\'s VGA port. The nine signal pins transmit the video signal from the PC to the monitor. The three orientation pins, which have locking tabs, ensure that the connector is properly aligned and securely connected.The shielding layers of the D-Sub Connector block unwanted interference from the environment and provide better signal integrity than that of an unshielded connector. The inner foil layer is connected to the shell to provide a ground connection to the signal line, while the outer braid layer is connected to the shell and provides additional protection against EMI and RFI.Finally, the shells of the D-Sub Connector are designed to provide physical protection for the pins and sockets and form an airtight seal that prevents dust and other contaminants from entering the connector. The outer edges of the shell have additional metal parts, called flanges, which are designed to provide extra physical protection and secure the connector when installed.In summary, the 172-015-112-021 D-Sub Connector is a 15-pin connector that is used for VGA video and game console applications. It has two rows of 7 pins spaced 0.200 inches apart and an additional row of 1 pin spaced 0.100 inches below the two rows. It is double-shielded and comes with an outer shell that provides physical protection and a tight seal to prevent the intrusion of contaminants.
