A '''jumper wire''' also known as '''jumper link''', '''jumper''', '''jump wire''' or '''DuPont cable''' is a connecting wire, bare at the ends or terminated with some type of connector. These are

A DuPont crimp consists of two parts, 0.1” (2.54mm) housing and separate metal crimp terminal. The AWG for wire generally used is 22, 24, 26 or 28 (standard ribbon cable) and a maximum diameter of 1.57mm.<ref>Molex data sheet [http://www.molex.com/webdocs/datasheets/pdf/en-us/0008500114_CRIMP_TERMINALS.pdf 08-50-0114]</ref><ref>Molex data sheet [http://www.molex.com/webdocs/datasheets/pdf/en-us/0008520072_CRIMP_TERMINALS.pdf 08-52-0072]</ref>
Using the proper crimping tool makes a good crimp joint easy. A properly crimped joint does not need soldering and is more than strong enough.<ref>[http://renoirsrants.blogspot.co.uk/search/label/Crimping Crimping], by Dave Renoir, 20 October 2011</ref> Most crimp terminals are designed to be crimped, not soldered. Soldering a crimped terminal may weaken the mechanical connection, reduce electrical conductivity, and damage the terminal.
