Rectangular connectors, also known as headers and male pins, are used to form an electrical connection between two printed circuit boards (PCBs) or electronic components. The 75869-108 is a type of rectangular connector that is widely used in the industrial, military and aerospace industries. This article will look at the application field and working principle of the 75869-108.

Application Field

The 75869-108 is a rectangular connector that is specifically designed to meet the demanding requirements of aviation and ground vehicle applications. It is manufactured in accordance with commercial and military standards, and has an electrical performance environment of 5-3000MHz. This makes it ideal for applications that are exposed to extreme temperatures, vibration, or other environmental fluctuations. It is also suitable for applications which require rigorous electrical isolation requirements.

In addition, the 75869-108 is designed with a snap-in mounting system to optimize the connection for ease of routing and wiring, making it ideal for applications such as internal wiring in cabinets, backplanes, and cable harnesses.

Working Principle

The 75869-108 rectangular connector utilizes a two-pole contact system. The two-pole contact system consists of two contact elements, one female element and one male element. The female element is a socket assembly composed of an insulating base plus a female contact. The male element is a terminal assembly composed of an insulating body and a male contact. The male contact of the male element is designed to fit into the female contact of the female element, forming an electrical connection between the two components when the two elements are mated.

Once the two elements are mated, the male element is secured to the female element with a locking tab on the insulating body to prevent unintentional separation. This design minimizes the risk of accidental disconnection in rugged applications.
