DE9S0L2A190A197

D-Sub Connectors are an important class of connectors used in the application of electrical engineering. The DE9S0L2A190A197 connector, also referred to as a D-Sub mini-male connector, is a commonly found form of D-Sub connectors.

Application Field

The DE9S0L2A190A197 is primarily used in applications that require the connection of smaller electronic components, such as resistors, transistors, and integrated circuits. Examples include personal computer audio components, external modems, and headphones. This connector type is also frequently used in professional audio and video applications. DE9S0L2A190A197 connectors are known for their reliability due to their positive latching, preventing them from accidentally coming loose. This type of connector also offers strong EMC performance.

Working Principle

The DE9S0L2A190A197 connector is a mini-male type of connector, with nine pins arranged in a row. Two of the pins are for ground connections, one each for the positive and negative voltage lines, and the remaining five pins for signal transmission. The connector also features an electrical shield for improved EMC performance. The internal structure of the connector consists of a plastic body, contact pins, insulation sleeves, shell and sheet metal. The pins are surrounded by a plastic insulation sleeve and are connected via a grommet. The shield consists of a sheet metal enclosure that surrounds the outside of the connector.

When plugging and unplugging the DE9S0L2A190A197 connector, the latching system serves to secure the two halves together. The male portion features two "teeth" which securely latch into place when inserted into the female portion of the connector. The two ground pins are securely connected when the latching system is engaged, ensuring reliable electrical connections. The resistance provided by the contact pin\'s electrically conductive surfaces also serves to maintain a secure electrical connection.

Conclusion

The DE9S0L2A190A197 is a reliable and cost effective connector, which is often used in the connections of small electronic components. The use of a positive latching system ensures reliable connections, while its electrical shield improves the EMC performance. Furthermore, its small size makes it ideal for applications where space is limited.
