D-Sub, D-Shaped Connectors - Accessories - Jackscrews

Jackscrews, also known as thread-forming screws or thread-cutting screws, are widely used in many types of electronic devices and circuits. Specifically, 4750-3 jackscrews fit into D-Sub connectors, as well as other types of connectors, and often feature a steel self-threading body and machine thread components. The shape of the connector is the same as that of a D-shaped object, featuring two steps of equal size and shape.

Jackscrews are primarily used to provide a secure electrical connection between any type of electrical component, with the two main functions including the fixing of electrical connectors and providing grounding contact points. These components can be found in a variety of applications, including computing and telecommunication devices, automotive electronics, and other consumer electronic devices, particularly those with flat panels.

The 4750-3 jackscrews are designed with a socket head, which can be used to secure the screw to the device. The body of the screw is made from steel, which is heat-treated for increased stability and durability. The inside of the jackscrew is fitted with a fine-toothed screw thread, which can be used to attach contact pins, and provide a low impediment connection. The steel body of the screw is also used to provide a surface for the contact pins, which increases the overall contact area.

When it comes to the working principle of the jackscrews, it is important to understand the two main components of the device; the contact pins and the threaded body. The contact pins are able to create an electrical connection through mutual contact with each other and other metal parts, which is enabled by the screws. The threaded bodies of the screws are then used to secure the contact pins to the device, while providing a grounded connection from the device to ground.

The 4750-3 jackscrews are also available with an optional knurled head, which can be used for additional ground connection points. This type of head also provides a stable connection, which prevents slippage and loosening of the screws. It also ensures a secure ground connection, which is essential for ensuring a reliable connection. In addition to the contact pins, the threads of the jackscrew are also used to provide a surface for contact with other metal parts, which helps to increase the overall contact area.

Overall, the 4750-3 jackscrews are essential components for a range of electronic devices and circuits. The socket head, which can be found on the jackscrews, provides a secure connection, while the threaded body enables the secure attachment of contact pins. The contact pins are then used to create an electrical connection, while also providing a ground connection for the device. Finally, the knurled head provides a stable connection, which prevents slippage and loosening, while also ensuring a secure ground connection.
