D-Sub connectors, sometimes referred to as D-shaped connectors, are electrical connectors used in various types of equipment. The D in the D-Sub stands for “double”, signifying that two parallel rows of pins are used. The 740-331570 specifically refers to the particular type of jackscrews used in some D-Sub connectors produced by Amphenol.

Jackscrews are small mechanical fasteners used to secure connectors or other objects to host machines. The 740-331570 jackscrews are specifically designed for D-Sub connectors and can be used in a variety of applications. Common uses include the attachment of a cable hood, or other enclosure onto the connector. The 740-331570 is sometimes referred to as panhead screws, as they have a rounded, “pan-like” head shape.

The 740-331570 jackscrews measure 18 mm overall length and have a thread diameter of 3.3 mm, with a pitch of 0.50. The jackscrews are brass nickel plated and have a 0.6 Nm (newton-meter) tightening torque. This torque is normally sufficient to provide secure contact between the connector and the host.

The 740-331570 jackscrews are typically used in applications where the D-Sub connector does not come pre-installed with a hood or enclosure. In such cases, the jackscrews are used to firmly secure the housing and cable to the connector, thus providing protection from external influences.In addition, the jackscrews ensure robust contact between the connector and the host, resulting in a reliable connection.

The 740-331570 jackscrews can be used in a variety of applications including industrial applications, military applications, and telecommunications applications. They are also used to mount quick-disconnect connectors, such as those found in computers and other electronics. Finally, the jackscrews are commonly used on D-sub back shells, which are components used to join and support two or more electrical connectors.

Jackscrews can be used in a variety of applications, including those involving different types of connectors. The 740-331570 jackscrews are specifically designed for D-Sub connectors and provide robust contact between the connector and its host. With its brass nickel plating and 0.6 Nm tightening torque, the 740-331570 jackscrews are sure to provide reliable contact and ample protection from external influences.
