These 10-pin IDC (ribbon crimp connectors) can be snapped onto 10-wire ribbon cable to make your own cable assemblies and keep your connections organized. The connector breaks the 10 conductors out into 2 x 5 pins with a 2.54mm pitch.  Simply press the connector onto your ribbon cable, no soldering required. The cap portion of the connector can be removed, allowing these to be installed mid-cable as well.
