Rectangular connectors, also known as rectangular plugs or rectangular sockets, are used to join two or more wires, cords, or cables together. They are widely used in a variety of electrical, electronic, and other cases for the connection of power, data, and communications.

Connectors are made up of two parts – the plug and the socket. The plug has a contact which is inserted into the socket and connected by a series of terminals. The plug and socket also have an insulation material between the contacts to protect from electric shock. Rectangular connectors are usually constructed in one of three types: standard DIN style, mini-style, and high-density. All three versions have different characteristics and therefore can be used for a variety of applications.

Standard DIN style connectors are often referred to as “ventilated” due to their wide range of contact arrangements which provide a wide range of electrical characteristics. These connectors are typically applied in power, control, data, and communications cables, as well as for shielding and grounding applications. Mini-style connectors are designed for low-voltage and low-current applications, such as computer interface and communication systems. High-density connectors are designed to optimize the space available for limited field applications, such as automotive or industrial. They are also used in high-power applications, such as robot arms and other motion control equipment.

The working principle of a rectangular connector is based on creating an electrical connection between two or more components. The contacts of the connector are designed to provide an electrical path between each of the components and the outer housing of the connector which provides insulation between the components and the outside world. The outer insulation of the plug and socket are usually made from plastic, rubber, or metal.

The standard contact configurations of rectangular connectors are usually male or female. Male contacts are designed to be inserted into female contacts and connected by a series of terminals. The plugs typically have two or three terminals depending on the application, while the sockets normally have three or four. Different types of contacts can be used depending on the application, such as insulated wire and ring terminals.

The contacts of the plug and socket may also have a variety of other features, such as polarized designs which help prevent the incorrect insertion of the plug into the socket. This is particularly important in high-voltage and low-voltage applications. Other features may include waterproof seals, dust or splash guards, LED indicators, and screw or clamp mechanisms to provide a secure connection.

Rectangular connectors are widely used in a variety of applications due to their ability to provide a reliable connection, their affordable cost, and their wide range of features. They are typically used in home, industrial, and communication applications.
