D-Sub, D-Shaped Connectors - Contacts

D Sub Connectors have been designed for various applications including machining, joining and fabrication solutions. The versatile D-shaped connectors are widely used for many configurations from single pin and double pin versions, to more complicated systems with hundreds of contacts. As with any type of connector, the choice of contacts for a particular application depends on the type of connection required and the environment in which it must operate.

The standard 166998-2 D-Sub connector design is credited to Deutsch for their original two-pin design, which is now used for all types of applications with contacts of varying shapes and sizes. An example of this is the commonly-seen D-Sub connector array that’s fitted to computers and peripherals. This type of connector is used to join two compatible devices together in order to transfer electrical signals.

Most D-Sub connectors use female and male contacts that are either crimped or soldered depending on the application and industry standards. Many types of contacts are currently available on the market including straight and right-angle contacts for both the connect and disconnect systems. Contact designs are tailored to the application requirements and must meet the relevant standardisation for safety and performance.

The design of the contacts for a 166998-2 D-Sub application will depend upon its use and the environment in which it is expected to operate. These may include pressure contacts for reliability in harsh environments, or spring contacts for better performance in low-power applications. There are also various contact sizes to choose from, and these will depend upon the frequency range and power handling ability of the devices in the network.

The working principle behind a 166998-2 type D-Sub connector is simple; a contact from the female connector mates with its counterpart contact on the opposing male connector. The contact connection is completed by a mechanical force, either by hand or a tool, such as a screwdriver. This ensures a secure connection between the two components.

The contact mating process of a D-Sub connector generally consists of two stages. Firstly, the contact of the male connector must compress in order to make connection with the opposite contact on the female connector. Secondly, a small amount of electrical current may be passed between the contacts, providing a guarantee of connection and ensuring that the electrical signal can be transmitted between the components.

The 166998-2 application field and working principle of D-Sub connectors provide an invaluable resource for those looking to join two components in a secure and reliable connection. By understanding the contact design, the environmental requirements and the applicable industry standards, a suitable D-Sub connector can be selected for any application.
