91911-31509

Rectangular connectors are a prevalent type of interconnect device in the electronic industry that is intended to allow the transfer of signals or power between printed circuit boards (PCB), discrete wires, or other components. The 91911-31509 rectangular connector is a specific type of multipoint connector, commonly referred to as an array, edge-type, or mezzanine-style connector, that provides the platform for multiple-connection needs in many direct application fields.

This particular type of connector is designed with an edge type card with multiple contact points that securely locks into a mating connector. This imparts greater reliability, stability, and robustness, especially in board-to-board interfacing, than that of a conventional header pin-style contact. Commonly used in a variety of areas, including industrial instrumentation, medical electronics, aerospace, and defense, the 91911-31509 connector provides a reliable connection between devices. Special features also include Signal, Power, and Ground contacts on the same pin.

The connectors are composed of several necessary parts, such as a receptacle, backshell, and crimp contacts. The receptacle is an insulating component with metal sleeve that provides a locating feature for the crimp contacts when inserted in the housing, and it also helps to prevent misalignment of the contacts when mated into the connector system. The rear of the receptacle and cable are then protected by the backshell, forming an environmental seal and strain relief. Lastly, crimp contact kits are usually supplied with a wire/cable size range from maximum of 0.80 mm2 to 22.2 mm2.

The working principle of the 91911-31509 Multipoint Edge-type Connector relies on the central pin contact system, which is directly inserted into the receptacle. Once inserted into the housing, a robust spring-loaded contact mechanism applied pressure to ensure a reliable and secure contact. It also provides an audible response, creating a solid connection as the pin is fully inserted and swept into its locked position into the receptacle. This helps ensure a good connection every time.

In order to terminate the wire/cable to the contacts, the connector uses a crimping system. With the use of crimp contact kits, the contact is efficiently mated to the wire and inserted into the receptacle. Strain relief fixations can also be used for improved security in applications in which vibration is involved.
