D-Sub connectors have been in use for many years in a variety of application fields. These connectors are used in many industrial, automotive and video applications, and are particularly useful in providing reliable electrical connection, as well as physical protection for connections. The "D" shape of these connectors allows them to have an efficient mechanical connection, and makes them especially useful in high-density applications.

The 749195-2 is a particular type of D-shaped connector known as a backshell. These connectors are designed to help when wire routing is tight, as the shell helps to prevent strain on the wiring. This type of connector offers a ‘snap\' type connection, so installation and maintenance is convenient, and the mechanical connection is sealed and secure. The 749195-2 also has a latched type cable clamp, which prevents the connector from being disconnected from the wire.

The 749195-2 has a particular working principle. The backshell is made up of two half shells connected together with curved grooves and finger tabs. When together, the finger tab provides a secure locking lever to grip the cable into place. The design of the double cavity allows for the shield to be connected to the housing. The curve of the shell creates a 360 degree engagement, providing a secure grip on the cable and a tight seal.

When using the 749195-2 D-sub backshell connector, the user has a number of options in terms of the type of cable, strain relief and shielding. The cable type can range from small signal wires all the way up to large diameter power cables. The strain relief can be provided by different choices of crimp, compression or push-in strain relief. Additionally, the connector can also provide a choice of EMI/RFI shielding. This can be either threaded or unthreaded shielding that can be added to the connector in order to protect circuits from electromagnetic interference.

The 749195-2 D-Sub backshells are particularly useful when creating a secure connection in tight spaces and areas. By providing a choice of cable style, strain relief and shielding, a user can tailor the connection to their exact needs. This type of connector also provides an efficient mechanical connection, protecting the wire from any kind of strain. The two half shells combined with the curved grooves and finger tabs allows for a snapped locking lever which provides a secure and strong connection.
