D-Sub, D-Shaped Connectors, and accessories such as Jackscrews, can refer to a broad range of connectors used in various electrical applications. Applications for these connectors can range from consumer electronics, computer hardware, and networking to professional commercial or industrial solutions. With all these different applications, comes an understanding of the different working principles of the connectors. This article will discuss the 7231 application field and working principle of D-Sub connectors.

D-Sub connectors are most commonly used for serial connections, enabling two types of serial connection: RS-232, RS-422, and RS-485. The type of serial connection is dependent upon the specific type of D-Sub connector used. RS-232 is used for low-end connections, such as telephone lines, where only simple data signals are transmitted. RS-422 and RS-485 are more versatile applications, providing higher speed communication and transfer of larger volumes of data. These standards are used by modern businesses for point-to-point and multi-drop communication using channels up to 2KM in length.

The most common form of D-Sub connectors are 9-pin, 15-pin and 25-pin variants. The type of calculation pin is determined by the application. The 9-pin variants are used for low-speed serial connection applications such as RS-232, while the 15-pin and 25-pin variants are used with the more versatile RS-422 and RS-485 connections. All these connector variants come with specifications such as contact spacing, shell size, and signal lines. To meet these specifications, they usually come with different accessories such as jackscrews.

Jackscrews are a type of fastener which provide a secure connection between the female and male components of the D-Sub connector. A jackscrew consists of a threaded female component and a threaded male component with an internal groove. When the two are combined, the male component slides into the female component along the groove, and the threads of each piece interlock. The jackscrew is then secured by a nut, which is tightened to prevent movement of the connector. The size of jackscrew can vary depending on the size of the connector, and they come with a range of specifications to suit different applications.

The 7231 application of D-Sub connectors covers a wide range of industries and environments, from consumer electronics and professional commercial solutions to industrial networking applications. These connectors are also available in a variety of different sizes and configurations, including 9-pin, 15-pin, and 25-pin variants. The most common application field is for serial connections, where RS-232, RS-422, and RS-485 come into play. To ensure a secure and reliable connection, D-Sub connectors come with accessories such as jackscrews, which provide a secure and reliable locking mechanism.
