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

The 91901-31169LF is a rectangular electrical connector commonly used for connecting and disconnecting circuit boards. It belongs to a category of rectangular connectors known as array, edge type, and mezzanine connectors (board to board).

Rectangular connectors are electrical devices designed for connecting and disconnecting circuit components without having to use soldering. The connector is available in a variety of shapes, such as square, circular, and U-shaped, for different applications. Array connectors allow a multiple connection of two or more circuits, edge type connectors are primarily used to connect boards edge-to-edge, while mezzanine connectors provide physical and electrical connection between mating printed circuit boards.

The 91901-31169LF is an example of a mezzanine (board to board) connector. It is designed to interconnect two boards of different size when only a discrete edge-card connector is used. It has a very small footprint, taking up minimal space on a board, while its high density design allows for the same number of signal pins to be packed into a much smaller space than a standard discrete connector.

The 91901-31169LF also features an integrated EMI shield that protects the electrical components from interference. The connector also uses flat contact technology, which ensures a reliable connection between circuit boards and components, due to the contact surface’s large contact area.

The 91901-31169LF is typically employed in application such as data communications, medical equipment, consumer electronics, telecommunications, and industrial automation. Due to its compact size and versatile design, the connector can be used in a variety of applications that require high-density integration and fast data transmission rate.

In terms of working principle, the 91901-31169LF is equipped with two separate contact pieces: a socket contact and pin contact. The socket contact is used to connect the pin contact on the other board, and the pin contact is responsible for transferring the electrical signals between the two boards. The two pieces are held together by a metal retainer that helps maintain a secure connection.

In conclusion, the 91901-31169LF is an electrical connector that is designed to be used for connecting and disconnecting circuit boards and components. It is a type of rectangular connector, belonging to the array, edge type, and mezzanine (board to board) category. It features an integrated EMI shield, flat contact technology, and a small, versatile footprint, making it a great choice for applications such as data communications, medical equipment, consumer electronics, telecommunications, and industrial automation.
