Rectangular Connectors - Headers, Male Pins

Rectangular Connectors are electronic components being used to provide an electrical connection between two or more individual terminals. They are often referred to as headers, male pins, and plugs and sockets. The rectangular connector is an effective and easy way to create a connection in an automated assembly line or a PCB board. The application fields of rectangular connectors can be divided into two main types.

1. Industrial Control Application Field

The rectangular connector is widely used in the industrial control field. It is used to connect programmable logic controllers (PLCs), control systems, electric motor starters, servo motors, electronic relays, and other specific components, as well as remote I/O networks, industrial components communication interface modules, etc. The standard interface has a wide range of application fields, and compared with other specific connectors, it has higher stability and versatility.

2. Automotive Application Field

As vehicles become increasingly automated, the need for reliable and efficient electrical connections increases. Rectangular connectors are used in automobiles, SUVs, vans, and pickup trucks. These connectors are used to connect the countless sensors and switches in the vehicle, from interior switches to the engine control module. They are also used to connect door components, window motors, solenoids, instrument clusters, seat motors, power locks, and more.

Working Principle

The working principle of the rectangular connector is simple. It consists of two parts: the header is mounted on the electrical component or printed circuit board (PCB), and the mating connector is connected by pins. The two connectors fit into each other, forming a solid connection between the header and the mating connector. The mechanical connection of the two connectors is reinforced by internal plastic latches that lock the connector in place. The electrical connection is established when the pins on the mating connector make contact with the pins on the header.

As mentioned earlier, the rectangular connector is an effective solution for creating electrical connections in automated assembly lines or PCB boards. It provides a reliable connection that is durable, impervious to vibration and shock, and easy to assemble and disassemble.
