1-102690-3

Rectangular Connectors - Headers, Male Pins are mainly used for signal transmission, data exchange, and power transfer in various electronic devices. The 1-102690-3 is a type of rectangular connector. Its application field and working principle are as follows.

Application Field

The 1-102690-3 type is a low-current, vertical-mounting type connector with a 3-mm pitch. It is mainly used in devices with low current requirements and a medium-sized PCB size, such as smart phones, tablets, modems, digital cameras, and other small portable electronic products. It is also suitable for applications that require a smaller pitch.

Working Principle

This 1-102690-3 type rectangular connector is composed of an insulated body, a terminal block, and a pin. The body has a three-wire type (positive, negative, and shielding), which is divided into two parts. The two parts are connected by bolts, and the terminals of the two parts are inserted into the terminal block at the same time. When connected, the terminal pins are connected by the pin through the two parts. The internal contact elements will be closely matched through the contact pin and the contact element, and finally form a transiently secure electrical film.

In addition, the two parts of the 1-102690-3 are integrated with anti-vibration claws, which can prevent false contact while ensuring a tight connection. It also provides flexible wire routing, excellent anti-vibration performance, and improved wiring efficiency and reliability.

Therefore, this 1-102690-3 type rectangular connector has strong signal transmission ability, good stability and reliability, especially suitable for low-current, small-pitch transmission with improved wiring efficiency. It is widely used in commercial, industrial and networking products.
