D-Sub, D-Shaped Connector JackscrewsD-sub, D-shaped connector jackscrews are small screws that are used to secure D-sub connectors to a panel or enclosure. D-sub connectors are a type of electrical connector that are commonly used in computing, communications, and industrial control applications. They are named after their distinctive D-shaped metal shell, which provides EMI/RFI shielding and mechanical support for the connector's contacts.
D-sub jackscrews are typically used to secure the connector to a panel or enclosure, and they are typically located at the corners of the connector shell. The jackscrews are tightened using a small screwdriver or hex key, which allows the connector to be securely fastened to the panel and prevents it from coming loose. Some D-sub connectors also use jackscrews to secure the individual contacts within the connector, which helps to maintain a reliable connection and prevent contact failure.
