Introduction

D-Sub Connectors, also known as D-Subminiature Connectors, are a type of electrical connectors used in a variety of applications. They are commonly used in computers, automotive systems, and medical equipment. The D-Sub Connector designation comes from its trademarked and patented naming system which simply uses the letter "D" followed by two numbers. The first number indicates the number of contact positions while the second number indicates the number of grounded shields which protect the contact pins. i.e., the DBMT9H4P0L4A191K87 Connector has nine contact positions and four grounded shields.

Application Field

The DBMT9H4P0L4A191K87 Connector is commonly used in applications such as automotive diagnostics, power systems test and measurement, and air conditioner systems. The connector is made of durable, corrosion-resistant materials, making it suitable for industrial usage. It is designed to offer reliable connections in harsh environments. The DBMT9H4P0L4A191K87 Connector has a wide temperature range, allowing it to be used in a variety of ambient temperatures from -40 to 200 degrees Celsius. In addition, the connector has a built-in dust cover to protect the contacts from external corrosive elements.

Working Principle

The DBMT9H4P0L4A191K87 Connector works on the same principle as other D-Sub Connectors. When the plug is inserted into the socket, the contacts within the header are compressed against the contacts of the plug. This action ensures that an electrical connection is made between the two components. Furthermore, the four grounded shields also provide additional protection against external electrical interference.The DBMT9H4P0L4A191K87 Connector also has a locking mechanism which provides a secure connection between the plug and socket. The connector utilizes two or more locking clips on the sides which keep the plug in place. This feature helps to ensure that the electrical connection is not lost, even in rough environments. The contact pins are usually made of a highly durable material, such as copper or brass, which ensures that the connection is reliable. The contact surfaces on the pins are also heat-treated, further enhancing their reliability. When the connector is released, the contact pins are pushed back to their original position and the two parts of the connector are electronically disconnected.

Conclusion

The D-Sub Connectors, such as the DBMT9H4P0L4A191K87, are designed to offer reliable electrical connections and are used in a variety of applications. The connector has a wide temperature range and offers a secure connection via its locking mechanism. The contact pins are made of a durable material and are heat-treated to ensure a quality connection. The four grounded shields also provide protection against external electrical interference.
