Rectangular Connectors - Headers, Male Pins are widely used in various electronic and electrical applications, such as computers, medical instruments, communications, consumer electronics, audiovisual equipment, automotive, and so on. Among them, 179846-1 is an important type used for making connections between two parts. Let’s find out its application field and working principle.

Application Field of 179846-1

179846-1 is a high-density board-to-board rectangular connector with header plugs, which is widely used in industrial control and other electronic fields. The size of this plug is 6.25mil*7.50mil, with 4 square pins and 1.27mm pitch. This plug is designed for connection with double sided PCBs, such as power line input/output, signal transfer, power charging and data communication. It is also used in other specific applications like making booms on aerial photography drones, connecting LEDs on light strips, etc.

Working Principle of 179846-1

179846-1 utilizes the slot type connector. There are two types of contact pins embedded in this connector - pin pads and socket pads. The pins are connected to the peripheral layer of the printed circuit board. When two components with 179846-1 are connected together, the pins of both components enter into the slots of the other component respectively. The pins are then barred and locked thanks to the spring in the slot and the inherent elasticity of the pins, resulting in a firm connection. The socket locking teeth, which are designed on the socket pads, guarantee that the connection between the two components can be released when needed.

At the same time, the contact system of 179846-1 is also using a pressure contact system. The pins are distributed inside the connector with a certain form and elasticity, and the side of the connector with the pins is installed in the housings of the two components to be connected. The pressure in the housing presses the pins, making them fit even better into the holes on the printed circuit board (PCB). This pressure contact system makes the connection even more secure and reliable, and also helps to decrease electrostatic interference.
