D-Sub Connectors – Accessories – Jackscrews

Jackscrews are an important accessory used mainly in D-Sub connectors. They are used to secure the male and female parts of a D-Sub connector together and to ensure a tight fit. Jackscrews are typically made of metal and come in various sizes.

The most common type of D-Sub connector is the DE-15, also known as an HD15. It uses a pair of small jackscrews that are inserted through the side of the connector and tightened to secure the two components together. The screws are then tightened using a small screwdriver, which applies a tremendous amount of force to ensure a tight, secure fit.

Jackscrews are especially important when a D-Sub connector is used in a high vibration environment. The screws prevent the connector from becoming loose, which can cause signal interference or electrical shorts. They also help to dissipate heat from the connector more efficiently, which is especially important in high power applications.

Jackscrews are also used in other types of connectors, such as USB and RJ45 connectors. In these applications, they are designed to provide a secure fit and to ensure that the mating parts are not damaged during installation. Jackscrews can also be used to secure bus bars or metal plates used in various electrical systems.

In addition to their primary application as a fastener, jackscrews can also be used as an adjustment mechanism. This is especially useful for adjusting the height of D-Sub connectors in order to ensure a proper connection between two components. By adjusting the height, or “depth”, of the connector, it is possible to achieve a perfect connection between the parts. This is especially useful for connectors that are used in confined spaces, where the depth of the connector must be adjusted in order to ensure a proper fit.

Overall, jackscrews are an important accessory to be used in any D-Sub connector application. They provide a secure fit and ensure that the mating parts are not damaged during installation. They are also used to provide a means of adjustment, in order to adjust the depth or height of the connector. Furthermore, they play an important role in dissipating heat from the connector and preventing signal interference. Without jackscrews, the secure fit of the connector would not be possible, and the performance of the device would suffer.
