2143400-1

Rectangular Connectors - Arrays, Edge Type, Mezzanine (Board to Board)

The 2143400-1 connector is designed for use as a board-to-board connector in mezzanine and edge type applications. This type of connector is designed to provide the electrical interface between two printed circuit boards, without the need for a separate cable connection.

The 2143400-1 is a single row, right or left angle, 74 contact pin through-hole type connector that can be configured for either edge or mezzanine type applications. The pin count for the connector can range from 36-74 contacts. The contact material for the 2143400-1 connector is gold plated copper alloy.

Features

• Board-to-board contact interface
• Terminate with through-hole type soldering
• Reusable damp-proof shroud
• Positive double latch system
• High mating/unmating forces
• Polarized contact design

Applications

The 2143400-1 connectors are ideal for connecting the various boards in mezzanine and edge type applications. The through-hole type contacts make these connectors especially suitable for high power applications. These connectors are commonly used in printed circuit boards (PCB) within computers, displays, cameras, and other entertainment and industrial electronics.

Working Principle

The 2143400-1 connector consists of a housing and a stainless steel tubular pin that passes through the board. The pin is held in place in the housing by means of a crimp retention mechanism. The pin has a square cross-section which prevents rotation when the pins are inserted in the board. The pin has a gold plated copper alloy end contact which makes contact with the mating connector. The female connectors use two latch arms which are actuated by a leaf spring. These arms are pressed apart and provide an audible click when the connector is mated.

The performance of the 2143400-1 connector is determined by several factors. The contact material used for the pins, and the pin diameter are important design features that determine the electrical performance of the connector. The board to board positioning accuracy and proper mating of the connector is dependent upon the quality of the mechanical design features of the connector.

The 2143400-1 connector is an efficient and reliable means of providing board-to-board electrical connections in a variety of applications where space is a critical factor. The connector’s simple design, through-hole type contacts, and reusable shroud make it an excellent choice for demanding mezzanine and edge type applications.
