D-Sub connectors are a commonly used type of connector, known as D-shaped because of their structure. The most common form resembles a trapezoid, with two rows of pins and sockets. To use the D-Sub connectors properly, many different components are needed. Backshells, hoods, mounting hardware, and contact protection are all necessary parts that make up a complete D-Sub application. 8655MH2501BLF is a specific D-sub Backshell used to protect the sensitive D-Sub contacts and provide strain relief for the wiring harness or assembly. This article will discuss the application field and working principle of the 8655MH2501BLF.

Application Field:

The 8655MH2501BLF is a metal D-Sub backshell that is designed to provide strain relief and contact protection for the wires and socket connections. These backshells provide secure connections, and are perfect for use in applications that require extreme environment or vibration, such as in aerospace, military, and automotive applications. Additionally, the 8655MH2501BLF is certified for use in applications up to 125°C, so it is also great for use in high-temperature environments. The backshell is designed to fit a variety of D-Sub connectors, and the screws on the body provide additional security for connecting cables and wires.

Working Principle:

The 8655MH2501BLF is designed to provide protection for the delicate D-Sub contacts, shielding them from corrosion and wear. It is composed of a two-piece ferrule assembly that attaches to the connector body. The two halves of the ferrule come together and are secured by a semi-captive hex nut that is tightened around the outer circumference of the connector. When connected, the outer part of the ferrule fits snugly around the D-Sub contacts, and the inner portion provides a tight connection between the cable and socket. The semi-captive hex nut is designed to securely clamp the metal ferrule in place while keeping the connection points secure.

In addition, the 8655MH2501BLF also provides strain relief for the wiring harness or assembly. This is achieved by the optional "mouse-rabbit ear" strain relief clamps that are located on each side of the backshell. These clamps help reduce wire pullout forces by contraction and gripping the wires when tightened. This provides additional stability for the connection, ensuring that wires remain in place even during periods of harsh vibration.

The 8655MH2501BLF is a reliable and essential piece of equipment for applications that require durable, secure connectors. Its features make it perfect for use in aerospace, military, and automotive applications, as well as in high-temperature environments. The backshell protects the cables and wires, while its strain relief clamps help ensure that the connections remain secure even during times of intense vibration.
