Rectangular connectors - Housings are electronic components used to join two or more wires, cables or printed circuit boards. These connectors are used in a variety of applications, such as consumer electronics, medical equipment, and industrial and military applications. The rectangular shape and the various terminations of the connectors make them suitable for a variety of high-current, high-power connections. In this article, we\'ll look at the application fields and working principle of rectangular connectors.

Application Fields for Rectangular Connectors

Rectangular connectors have a variety of applications in the electrical and electronics industries. These include high-current and high-power applications found in industrial, military, medical and consumer electronics. High-current connectors are often used in applications such as generating plants, battery and charger systems, and telecommunications equipment. High-power applications of rectangular connectors include server racks, fuse boxes, uninterruptible power supplies and HVAC systems.

Rectangular connectors are also used in less demanding applications. These range from HDMI connectors used to connect digital audio/video equipment to RJ45 Ethernet connectors used for computer and LAN networks. In addition, rectangular connectors are commonly used in consumer electronics applications such as microwaves, air conditioners, televisions and audio/video equipment. These are available with various termination configurations to suit the application.

Working Principle Of Rectangular Connectors

The working principle behind rectangular connectors is the same as for other types of electrical connectors. The connector comprises two or more conductors, which connect to each other to create a secure connection. The connectors are soldered, crimped or turned to create electrical and mechanical continuity between the conductors. Additionally, the connectors are sealed and wired to ensure a safe electrical connection.

Generally, a rectangular connector is made from a thermoplastic material with a metal insert. This insert can be either a stamped or machined piece of metal. The metal insert acts as the mating surface, and when two connectors are mated, the metal inserts create a secure and reliable electrical connection. Other types of connectors, such as ones made from plastic or rubber, do not have a metal insert. Instead, they rely on two surfaces being tightly pressed together for the electrical connection.

To ensure the secure connection is maintained, the two connectors must be mated correctly. The most common method of mating is to align the metal inserts of the two connectors. This is done by aligning the lugs, pins or tabs on the metal insert with those on the other connector. The connectors can then be pushed together until there is an audible click or the connector locks into place. Additionally, the connectors can also be rotated to ensure the metal inserts are properly aligned.

Conclusion

In conclusion, rectangular connectors are a versatile and reliable form of electrical connection that is used for a variety of high-current, high-power and low-current applications. The working principle behind these connectors is the same as for other electrical connectors. Metal inserts on the connector are mated with those on the other connector to create a secure electrical connection. Additionally, the connectors must be correctly aligned before mating to ensure a secure connection.
