D-Sub Connectors
D-sub connectors are a family of electrical connectors that have been widely used in numerous applications for over 60 years, with the number 205562-3 being part of this series. This type of connector is commonly used where multiple connections are required and when using a small form factor.Overview
D-sub connectors are comprised of two components: the receptacle and the plug. The receptacle is inserted into the panel, or wall, with the female pin contacts being soldered to their target connector. The plug is then inserted into the receptacle and the male pin contacts are soldered directly to the wires or cables. This is the most common type of connection technique used in D-sub connectors, however, it is also possible to insert the conatacts in the receptacle, or house, instead in cases where soldering is not an option.The common factor in D-sub connectors is its physical size and its two-piece construction, with a range of contact arrangements ranging from 8-pin to 50-pin.Appearance
The 205562-3 is a type of D-subminiature connector, featuring a full metal hood with a shrouded shell coupled to a die cast zinc alloy contact carrier housing. This type of connector also has a current rating of 12amps maximum (6Amp continuous) and a dielectric withstanding voltage of 1,000 volts.Application Field and Working Principle
The 205562-3 D-sub connector is predominantly used in industry applications, particularly in applications such as networking and aviation. In these applications the type of connection is directly dependant on the pin configurations. The main components of the 205562-3 are its front-mount receptacle, the back-mount socket, and a range of interchangeable contacts.The working principle of these types of connectors relies on the application of pressure that is generated between the pin contact and its mating component. This pressure is necessary in order to create the electrical connection, but should be limited as excessive force can damage the contact or receptacle.Conclusion
The 205562-3 is a type of D-sub connector that has become a popular choice for industry applications, due to its two-piece construction and its various pin configurations. It is usually used when a small form factor is needed yet multiple connections are needed. Working principle wise, these type of connectors require sufficient pressure to create electrical connections, but this pressure should be limited in order to avoid damage.
