Rectangular connectors are one of the most widely used types of components in electrical systems. They are used in a variety of applications, from consumer electronics and computer equipment to industrial and automotive applications. In this article, we\'ll take a look at what rectangular connectors are and explain their application field and working principle.

At its most basic level, a rectangular connector is simply two pieces of metal that connect two conductors or wires together. The connector consists of two sections, a male pin that is inserted into a female socket. The male pin and female socket are typically manufactured from either copper, aluminum, or brass with a tin or nickel plating. The plating helps prevent damage caused by corrosion.

Rectangular connectors are typically categorized according to their shape (e.g., square, right-angle). In addition, they can be further categorized according to the number of contacts they have. For example, DIN-style connectors are found on external peripheral devices like keyboards and mice and typically have two to five contacts.

The most common application of rectangular connectors is in electrical and electronic systems that require the transmission of signals. In these systems, the connectors are used to provide the necessary electrical linkage between two components. For example, they are commonly used to connect a USB cable to a computer or to connect a printer to a computer. Another common application is in automotive wiring systems where the connector is used to connect different components such as lights, switches, and sensors.

The working principle of rectangular connectors is quite straightforward. The male (pin) and female (socket) connectors are designed so that when they are mated, the spring action on the terminals pushes them together. This is what forms the electrical connection between the two components. The number of contacts on the connector determines the number of electric power signals that can be transmitted between two points. Depending on the type of connector, it may also be designed to carry signals for different types of data, such as analog or digital.

It is important to note that some rectangular connectors come in multiple sizes, which makes it possible to use them in different applications. The size of the connector is determined by the size of the wire or cable that is being used. For example, if a thicker cable is going to be used, then a larger connector should be used.

Overall, rectangular connectors are an essential part of any electrical or electronic system. They offer the necessary electrical connection between two components and, depending on the type, can also be used to carry electric power signals, digital, and/or analog data. They come in a variety of sizes, shapes, and contact configurations, making them suitable for a variety of applications.
