Rectangular connectors are wiring devices consisting of contacts, plastic housings, and contacts. They offer quick connection opportunities for digital, analog and power circuits. They come in a variety of shapes including headers, specialty pins, board mount, and high power. Here we will explain the different applications and working principle of rectangular connectors.

Applications

Headers. Headers are the most commonly used types of rectangular connectors used for a variety of applications in the commercial, industrial, medical, and automotive industries. They offer a quick connecting system for digital circuits with just two rows of pins. They are usually used to connect two devices such as an IDE hard drive to a motherboard or a device to a circuit board. They are also used to connect multiple pieces of test equipment such as ammeters, voltmeters, and oscilloscopes.

Specialty pins. Specialty pins are a type of rectangular connector specifically designed for certain applications. They typically have two or three rows of pins and can be used to connect a device to a circuit board or a device to another device. They are often used in medical devices, automotive systems, and military equipment.

Board mount. Board mount rectangular connectors are designed to be mounted directly onto a circuit board. In most cases, this type of connector is used to connect two circuit boards together, such as a laptop to a desktop PC. They are also used to connect two microcontrollers, as well as to connect a device to a circuit board.

High power. High power rectangular connectors have two, three, or four rows of pins. These are designed for applications where a higher current flow is needed, such as for connecting a power supply to a device. They are also used for connecting high-power motors and other high-power electronics.

Working Principle

Rectangular connectors work by using pins to make electrical contact between two circuits. The pins are generally made from copper alloy and are insulated by a plastic coating. When the pins are inserted into the connector, they make contact with the other circuit and allow electricity to flow. The amount current that can be passed depends on the size of the pins and the type of connector.

The plastic housing of the connector houses the pins and forms the mechanical contact between the two circuits. The housing is also designed to prevent the pins from coming loose and help to maintain electrical contact. In most cases, the housing is also designed to prevent dust and debris from entering the connector and damaging the pins.

Rectangular connectors are also designed to be strong and durable. They are usually made from either polyethylene or nylon and are designed to resist corrosion as well as everyday wear and tear. This makes them an ideal choice for applications where the connectors need to be used in extreme temperatures or harsh environments.

In conclusion, rectangular connectors are wiring devices consisting of contacts, plastic housings, and contacts. They are available in a variety of shapes and sizes including headers, specialty pins, board mount, and high power. They offer quick connection opportunities for digital, analog and power circuits. They work by using pins to make electrical contact between two circuits and are designed to be strong and durable.
