Application Field

20021321-00056D4LF fall into the category of rectangular connectors – headers, receptacles and female sockets. Specifically speaking, such rectangular connectors are especially designed for the hardware connections of hybrid highly dense circuit boards such as printed circuit board, flexible printed circuit board, flat cable, shielded cable etc.

Working Principle

All the electrical terminals inside the rectangular connectors must be equivalent in current, voltage, and power to form an electrical circuit. The rectangular connectors have two parts, including header pins and receive terminal, where the pins are connected to the tail or path on the board. Generally speaking, the receiving terminal is made up by two parts--insulation or shell and the contact. Once the necessary number pins have been connected to the board or cable, the insulation shell is ready to be mounted and screwed in. The shells are placed above the pins by pressing or clamping. And then, the contact is chemically bonded to the pins. As a consequence, the assembled rectangular connectors can provide strong, durable, secure and hermetic connections between two components.
