D-Shaped Connectors are immensely useful accessories for the connectors or modules industry. They enable the assemblage of soft-shell connectors in a range of configurations and can even be used to assemble rack-mountable connectors. The Jackscrews application field and working principle of these connectors are explained here.

Jackscrews are used for securing soft-shell connectors. Typically they consist of a mating pair of screws and nuts that can be threaded into the threads of the connector or module. The purpose of the Jackscrews is to firmly secure the soft-shell connectors into the enclosure or chassis. As such, Jackscrews are normally used together with lock washers, which ensure that the screws do not come loose due to vibration.

In terms of the working principle of Jackscrews, they consist of a screw portion and a nut portion. The screw portion is threaded into the connector or module and the nut portion is screwed into the chassis, securing the connector or module firmly in position. The use of lock washers ensures that the screws are not loosened due to vibration.

The proprietary 3344-38 Jackscrews is designed to work with high-power cable connectors, cables and modules. The high strength thermal plastic insulation provides excellent insulation for high-powered interconnects. The 3344-38 has an increased torque rating of up to 54 in-lb and the anti-rotation feature prevents any rotation of the threaded lock screw.

The connectors in this application field are also known as threaded stay-puts or threaded locking screws. The threaded stay-puts have the same threading and security levels as the 3344-38 Jackscrews and provide increased stability within the cable connector, module or mounting assembly. The threaded locking screws are the most secure form of Jackscrews, and they are threaded into the inner surface of the enclosure or chassis, providing a permanent bond.

In conclusion, Jackscrews are invaluable accessories for securing soft-shell connectors. The 3344-38 Jackscrews are specifically designed for high-power cable connectors, and have a high torque rating and anti-rotation feature for added security. The threaded stay-puts and threaded locking screws are also varieties of Jackscrews, and provide additional stability and security.
