Rectangular Connectors - Housings

Rectangular connectors are an integral part of today\'s electronic devices. They provide an easily accessible interface that enables a secure mechanical and electrical connection between two or more components in a system. Connectors in general can come in a variety of form factors, including rectangular connectors.Rectangular connectors are identifiable by their precise and uniform shape, typically featuring a square or rectangular shape with two five-sided faces. They typically come in two parts – the housing, which provides the physical framework for the connector and generally serves as mounting platform for the connectors; and the terminals, which provide a conductive path from the housing to the circuit or wire being connected. Housings for rectangular connectors are typically made from injection-molded thermoplastics and offer beneficial properties such as greater chemical and heat resistance, higher temperature performance, enhanced protection against electrical interference, and improved durability, compared to traditional metal-based connectors.These advantages are especially useful in military/aerospace, audio/video, medical, industrial, and other high-demand applications. Rectangular connectors are designed to respond to these needs, offering more reliable, versatile, and efficient connections.The working principle of rectangular connectors is mainly based on a contact system. This contact system allows the contacts to fit the rectangular connector housing in a variety of ways, typically by interlocking or latching the two parts together. The terminals then provide a stable and reliable electrical connection, with most contacts made of either brass or nickel.Rectangular connectors are further organized into three main categories – shrouded, free-hanging, and panel-mounted connectors. Shrouded rectangular connectors are designed for shielded cord-to-cord connections. They are typically sold incomplete and require the addition of contacts to complete the assembly. Free-hanging connectors offer versatile applications and can be used with all common crimp and solder contacts. They come pre-assembled, with complete contact surfaces. Panel-mount connectors are sometimes called pc-mount connectors, as they are typically mounted onto printed circuit boards.The appropriate type of rectangular connector and housing needs to be determined based on the specific application requirements. Connector manufacturers often provide documentation to assist in the selection process, such as technical drawings and detailed product specifications.In addition to choosing the right type of rectangular connector for the application, precaution must also be taken when handling. Connectors can become damaged during installation and result in a weaker connection and possible signal loss. When handling the wires, it is important to be careful and not exceed the minimum insertion force, as this can increase the risk of mechanical damage, resulting in poor electrical performance.To sum up, rectangular connectors are a versatile and reliable type of connector, used for a variety of applications ranging from commercial to industrial and military/aerospace. Both the connection type and the connector housing need to be selected based on the application requirements. Additionally, careful handling protocol is essential during installation.
