- 1393561-94D-Sub, D-Shaped Connectors - Accessories - JackscrewsD-sub connectors, also known as D-shaped connectors, are types of electrical connectors typically used in a wide variety of applications. They are also known as spade copper connectors or barrel connectors, depending on their shape. They are differentiated from other connectors like IEC 60320 CEE 7 due to their distinctive shape and usage in critical industrial and scientific applications.The jackscrews, also known as connector screws, are intended to secure the D-Sub connector to a mating device or surface. They are usually square-head threaded body screws with drilled and tapped countersink holes on the underside. The threads of the jackscrews pass through and are secured to the round barrel connectors. This ensures that the connection between the two components is secure and reliable.Jackscrews are available in a variety of sizes and styles, including round and square head, flanged and oval head, and even 3- and 4-lug spade connectors. No matter what type of connector being used, jackscrews can be used to mount and secure the connector securely. The most commonly used type for D-Sub connectors is a steel screw with zinc chromate finish.One of the benefits of using jackscrews for D-Sub connector mounting is that they provide a tight, consistent fit. Due to their shape, they provide a secure and permanent connection between the two components, eliminating the need for additional alignment or the fear of a loose connection. This eliminates potential performance degradation as well as potential service life issues from vibrations or accidental detachment.In addition to providing a secure connection, the screws make the installation process easier as they require no special tools or procedures. They also do not require a large hole to be drilled into the surface which is important when mounting these connectors to a PCB or panel. In addition to this, their low profile design helps to minimize cable visibility and reduces the risk of physical damage.Jackscrews are extremely versatile and are used in a wide variety of applications including industrial PCs, protection and process control systems, robotics, automation, and aerospace. They are typically available in pre-assembled or unbent configurations in both metric and imperial thread sizes.Overall, jackscrews are an essential component for the secure electric connection between two components in D-Sub connectors. They are relatively inexpensive, versatile, and simple to use. Furthermore, their tight-fitting connection ensures a secure connection without sacrificing performance. As such, jackscrews are one of the most reliable and widely used fastener solutions for D-Sub connectors.
