Rectangular Connectors - Housings
Rectangular connectors are a type of mating system that uses two or more parallel rows of contacts. These contacts are housed in an enclosure, which is typically made of plastic or metal. The most common type of rectangular connectors are D-Subminiature (D-Sub), which are used in computer applications to connect components. Other types of rectangular connectors include power barrier terminal blocks, jack connectors, zero insertion force (ZIF) connectors, and many others.

In terms of their applications, rectangular connectors are often used in industrial and military applications. Examples include computer and office equipment, consumer electronics, power and control circuits, audio and visual equipment, telecom systems, and automotive electronics. The main purpose of these connectors is to provide a reliable electrical connection among separate components. This can be done by either connecting them directly, or by using an intermediary adapter.

In terms of their working principle, rectangular connectors typically feature two sets of contacts that are housed in an enclosure. The enclosure is usually made of metal or plastic, and it consists of a series of metal or plastic labyrinths or passages that are designed to guide the contact pins into place. The contact pins are typically made of copper or stainless steel, and they are usually plated with a thin layer of gold or silver.When the pins enter the corresponding openings in the rectangular enclosure, the contacts create an electrical connection. This connection is then used to transfer signals or data from one component to another.

Rectangular connectors are advantageous because they are easy to install and maintain. Additionally, they require minimal connection surface area, and they can be designed for high-vibration environments. Furthermore, connectors that use rectangular housings are often designed to meet various industry and mil-spec standards, making them suitable for rugged applications. And finally, rectangular connectors are often used in applications where space is limited, such as in aircraft and aerospace applications.

In conclusion, rectangular connectors are used in a wide range of applications, from consumer electronics to military applications. They are sturdy and reliable, and they can be designed to meet military and industry standards. Their housings can be made of metal or plastic, and they use two sets of contact pins that are typically plated with gold or silver. Furthermore, connecting components via rectangular connectors is relatively easy, and the connectors can be designed to fit into cramped spaces.
