134752-3 Datasheet/PDFD-Sub connectors, also known as D-Shaped connectors, are a type of backshell which is designed to be formed in a distinctive angle. While they are most commonly used to terminate electrical connections to allow for cable connections within units or between devices, they can also be used in other applications such as mounting brackets and fuse boxes. The D-Sub also acts as a strain relief when used in cable connections, and serves to protect the underlying connection from possible damage.
The typical application of the D-Sub connector is in the form of a backshell, which is a hollow molded plastic shell that serves as a formfitting cover for the electrical connection. The backshell also houses a variety of hardware, including screws, snap-fit clasps, and rubber seals that provide mechanical and environmental protection against dust, contamination, and mechanical stress. The hoods also provide a degree of strain relief, as the material used in the hood construction resists deformation under stress. In addition, the hoods will generally enclose the electrical connection to the connector and protect it from the elements and possible injury.
The working principle of a D-Sub connector is based upon the fact that the backshell forces the connector into a specific shape, just like a conventional socket. This shape serves to provide a strong mechanical bond between the two connectors, preventing them from becoming disconnected. Once the connection is established, the two contacts can then be connected by soldering. The shell of the backshell provides the needed protection and shielding as well as allowing the connection to be accessed easily if needed.
The D-Sub connector is available in a variety of formats and sizes, ranging from the most popular 9-pin to the massive 34-pin connector. In addition, the connectors come in a variety of materials such as stainless steel, nickel-plated brass, and chrome plated steel. The connector is also available in various form factors, such as single, double, and multiple-pin. This variety of form factors allows for the connectors to be used in a wide range of applications.
The 134752-3 application field and working principle of the D-Sub connector is a popular choice for many different applications. Its versatility and strong mechanical bond make it an ideal choice for use in a variety of applications, including security systems, instrumentation, home entertainment systems, and many other applications. Whether the connector is being used in a small device or a large computer system, it will provide the robust connection needed to ensure reliable and secure communication.
