Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board) are a type of electrical connectors designed to join two separate components into a single unit. They are used in a wide variety of applications in industries such as aerospace, automotive, and electronics. These connectors are often used for shelf-mounted and PCB-mounted components.

The main types of rectangular connectors include: Arrays, Edge Type, and Mezzanines. Arrays have two or more connections in the same plane. These connections are interconnected and provide multiple signals such as power, ground, and signal. Array connectors can also be used for Power Over Ethernet (PoE) connectivity. Edge Type connectors have electrical contacts that are along the edges of the connector. These are typically used in high-speed devices and applications. The third type, Mezzanine (Board to Board) connectors, are usually used as a small scale PCB to PCB connection.

The basic working principle of rectangular connectors is that they enable electrical current to flow through the connection of two or more electrical wires. This connection can be used for power, data, and other signals. The connection is held in place by metal contacts, such as pins, sockets, and blades, which are placed into grooves in the connector. The contacts are then secured with a retaining clip. The contacts must be clean and properly placed in order to ensure a solid connection.

The different types of connectors may have slightly different working principles, depending on the type of connector used. Some connectors require a settling-in period and should only be replaced by a similar type of connector. Another important factor in the working of connectors is the electrical contact resistance. This resistance is the resistance between two conductors in the connector contact. If the resistance is too high, it can affect the reliability of the electrical connection.

In conclusion, Rectangular Connectors - Arrays, Edge Type, and Mezzanines (Board to Board) are common types of electrical connectors and are used for a variety of applications. The basic working principle of these connectors is generally the same, but the type of connector used has an effect on the working principle. In order for a solid electrical connection to be maintained, the contacts must be clean and properly placed. Additionally, the electrical contact resistance must be at a reasonable level in order to ensure a reliable connection.
