91910-21551

The 91910-21551 rectangular connector is part of the array, edge type, mezzanine (board to board) family of connectors designed to connect two printed circuit boards mechanically and electrically. This type of connector is characterized by a low profile and high packing density, and is much smaller than conventional rectangular connectors.

Application Field

The 91910-21551 rectangular connector is mainly used in electronic devices such as cell phones, digital cameras, DVD players, and gaming devices. It is especially useful for devices that require quick and reliable connection between the main circuit board and opto-mechanical modules, such as flash memories or LCDs. With its low profile and provided design flexibility, this connector is ideal for tight integration within the device, enabling a more compact form factor and better packaging for the device.

Working Principle

The 91910-21551 rectangular connector is designed to interconnect two printed circuit boards by using two identical mating connectors, with one on each board. The connector is composed of an array of high-frequency laminated contacts contained in housings, which can be mounted to the boards either by soldering or PCB press-fit, depending on the application requirements.

The procedure for using the 91910-21551 rectangular connector is based on the principles of compression and insertion. The two mating connectors are first compressed together, and then the pins are inserted securely into the pads of the printed circuit board. This ensures a reliable connection and provides the signal and power contacts with the necessary robust protection against EMI/RFI interference.

The connector also includes features such as keying and polarization for easy mating and unmating and ease of use. In addition, there are multiple housings, keying positions, and contact layouts available to meet a variety of requirements.

Conclusion

The 91910-21551 rectangular connector is designed to provide reliable electrical and mechanical connection between two printed circuit boards in a variety of applications. It has a low profile, high packing density, and a variety of design features that make it an ideal choice for tight integration in compact electronic devices. Its compression and insertion procedure provides a secure connection and its keying, polarization, and multiple housings, keying positions and contact layouts ensure ease of use.
