D-type connectors have been widely used for many years. They were originally developed by Cannon in 1952 and are now part of CanT. The D-type connector has been used as a multi-way connector in many applications, but it is probably the most widely known connector for RS-232 serial links. In fact, D-type connectors have been used for serial links on most computers for many years, and various types of D-type connectors can still be found on most computers today.
The D-type connector was originally called a subminiature connector, and the connector is now commonly referred to as a D subminiature connector. Although these connectors were small when they were first introduced, after so many years of development in the connector industry, many sophisticated connector products have been developed and designed in the world, so D-type connectors are no longer considered to be truly ultra-small Connector.
D-type connectors usually consist of two and sometimes more parallel connection rows. The connector has a D-format metal shell, which not only provides mechanical strength for the connector, but also provides some limited screening. The metal shell of the plug and the socket contacts to provide screening. In addition, panel mount connectors are usually fixed to the panel using nuts with additional threads that allow the mating connector to be fixed to it to prevent it from loosening.
In addition, the free connector can have a back shell that can provide shielding, and can be connected to a cable screen. Or if it is plastic, they can provide protection and also provide strain relief on the cable. As expected, the pin-containing connector is a male D-type connector, while the socket pin-containing connector is a female connector. The original D-type connector has two rows of pins, and the total number of pins is an odd number, which causes the connector to have one pin in another row, resulting in an e D shape, which also prevents the mating mechanism of the connector The direction is incorrect.
