There are many types of Connector Disconnects in use today in the aircraft industry, from blade to plug and socket. From here they split into even more types based on their class, size, contact arrangement number and style. Depending on the combination of these variations, they can effectively send and receive data, signals and voltages without interference from EMI and RFI sources, vibrations, moisture, heat and other environmental and mechanical conditions.
Aircraft today are made up of hundreds of electrical systems and subsystems traveling from wing tip to wing tip and nose to tail. These Connector Disconnects allow for ease of installation. Can you imagine stringing one wire at a time from wing to wing and tip to tail? What a huge hassle! Using a connector disconnect during installation, modification, replacement, or repair of the aircraft electrical wiring interconnect system (EWIS) substantially decreases aircraft “down time”. Additionally, connector disconnects for the EWIS as well as subsystems or components not only allow work to be done expeditiously, but they also maintain the integrity of the data, signals and voltages traveling through them.
