D-Sub, D-Shaped Connectors - HousingsD-Sub housings and connectors, commonly referred to as D-shaped connectors, are designed to interconnect the wires, cables, and other components used in electronics and electrical systems. The housings are typically constructed from rigid materials such as steel or plastic, and hold male and female or plug and socket contacts. Typically, the housings are designed to mount onto a PCB and accept one or more pins.Different models of D-Sub connectors are available in order to meet a wide range of application requirements. The 748642-1 is a popular flat-faced D-Sub housing that features dual-grip style contacts and dielectric strength up to 4kV. It is designed for a wide range of applications in both the commercial and industrial markets.The 748642-1 features a rugged construction and two levels of use, depending on the application. The first level of usage requires the insertion of a dielectric insert to create a secure seal between the male and female connectors. This prevents current leakage during operation and provides maximum contact area between the pins. The second level of usage is an open-face design, with no dielectric insert. When using this second level of usage, the pins are slightly exposed and can be accessed for assembly or repair.The 748642-1 is popular in many industrial applications, including control systems, instrumentation, and data acquisition. Its rugged design makes it suitable for harsh environments, while its reliability ensures it can be counted on in mission-critical applications. The 748642-1 is also commonly used in communications, aerospace, and automotive industries.The 748642-1\'s working principle is based on the electrical connection between male and female contacts in a single housing. The contacts are typically molded into the body of the D-Sub and include options for straight male and female styles or right-angle male and female styles. The contacts are wired in parallel with one another, which creates a connection when the male and female contacts contact each other. This allows signals to travel along the length of the entire connector.The contacts on the 748642-1 are made from various metals and alloys depending on the application. Often, gold-plated steel is used in order to provide reliable long-lasting connections. The contact coatings are also designed to resist corrosion and provide a secure fit with the mating connector. The contacts are secured in place through latching with the insert.The 748642-1\'s dielectric strength is rated up to 4kV, making it suitable for a wide range of operating voltages. Its current rating is up to 3A, with maximum contact resistance at 0.2mΩ. It is designed to meet the requirements of MIL-DTL-5015 connector series.To ensure high performance, the 748642-1 must be installed and maintained correctly. Before installation, the contacts should be cleaned with an approved cleaning agent and inspected for any signs of damage. During installation, the connector should be rotated through its full range of motion to ensure a secure connection. After installation, the connectors should be inspected for correct mating and fit.In conclusion, the 748642-1 is a reliable and rugged D-Sub housing suitable for many industrial application requirements. Its features include dual-grip style contacts and dielectric strength up to 4kV, as well as a wide range of current ratings and operating voltages. The contacts are secured in place through latching with the insert, and the connector should be rotated through its full range of motion to ensure a secure connection. With proper installation and maintenance, the 748642-1 can provide long-lasting and reliable performance.
