Rectangular Connectors - Headers, Male Pins are widely used in electronic products with electrolytic aluminum alloy materials. 5-641120-2 is no exception. Its application field and working principle are introduced in this paper.

5-641120-2 is a rectangular connector used in the field of electronic products. It is a 2-position male header and pin strip with 2.54mm pitch, 30V max current, 1A max contact resistance, 1.4N minimum insulation over and 6.5N (min) of terminal pull-off force. This product can be applied in many occasions such as computer, panel and wiring and is mainly used to connect the printed circuit board (PCB) with the circuit nodes, to realize the interconnection of internal and external circuit.

The working principle of 5-641120-2 connector is based on the principle of metal contact. It is usually composed of two parts, namely the female branch and the male pin. The former tightens the terminal point of the printed circuit board while the latter is used to connect the circuit component and the printed circuit board. There are some positions (generally 2-8 positions) on the female branch. These positions have an elastic contact part which can be connected to the corresponding male pin. After inserting the male pin into the female branch, connection could be finished.

What’s more, 5-641120-2 has a convenient crimping press-fit technology. Generally one side of the male pin is connected to the insulated wire with circular crimping die. With its large contact area and high elasticity, crimping has a strong connection. It is visualized and operable and is very suitable for the mass production of wiring harness.

It also has an important feature, which is resistance to vibration and shock. It is necessary for electronic products working in harsh or special environment. The 5-641120-2 connector has a waterproof function which can effectively waterproof and prevent corrosion on the circuit board and prevent the damage of contact areas caused by water. With special material, it can also be flame retardant property and meet the requirements of some industrial use environment.

In conclusion, 5-641120-2 has a small size and can be widely used in the networking and communication system, panel and computer. It’s strong connection, waterproof and flame retardant property can make it a good choice for electronic products.
