Introduction

The 91910-31351 is an array type, edge type and mezzanine (board to board) type rectangular connection used in high density applications. It features five pins mounted on a long edge of the rectangular body and is designed for a monolithic or split-molded type of circuit board configuration. It is an ideal solution for the creation, maintenance and protection of high speed and high frequency electronic connections, and its high density design helps to reduce board routing and improve board density.

Application Field

The 91910-31351 rectangular connector is designed mainly for signal integrity applications such as HDD/SSD, displays, graphic cards, and other high-speed and high-frequency applications. It has a Weigand-type design with two terminal pins that connect directly to the board, making it ideal for creating signal-interconnection between two boards that may be spaced apart. The flat contacts allow for easy and reliable connection with fewer bumps, making it suitable for automated processes such as automated die-bonding.

Working Principle

The 91910-31351 has a two-piece design that encompasses five pins each. Two of the pins form a base/ground connection while the other three carry signal-interconnection lines. The elastomeric body of the connector provides a reliable sealed connection that ensures correct mating and un-mating of the two parts. The contacts consist of two opposing spring terminals that form the electrical connection between the two boards and are permanently connected to each other. The contacts are rounded to ensure reliable contact alignment and secure contact retention during assembly. An insulating shell maintains electrical isolation between the contact pins and the outside environment.

Conclusion

The 91910-31351 rectangular connector is an ideal solution for high-speed and high-frequency applications due to its high-density design. It features five pins mounted on a single long side of the rectangular body and uses two head pins for creating a signal-interconnection. Its two-piece design and elastomeric body ensures reliable connection with fewer bumps and automated die-bonding. Its rounded contacts ensure reliable contact alignment and secure contact retention during assembly while its insulating shell maintains electrical isolation from the outside environment.
