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.
== Use in prototyping ==
Jumper wires of insulated 26[[American wire gauge|AWG]] wire terminated with [[crimping|crimped]] pins or sockets in plastic housing are used to make connections between [[pin headers]] or sockets. With 2.5 mm (0.1 inch) housing they're suitable for interfacing single board computers like the [[Arduino]] and [[Raspberry Pi]]. These will also fit without damage to interconnect the components on solderless [[breadboard]] although here 22 AWG solid-core hookup wire with bare ends can be used instead.<ref>[https://www.rapidonline.com/jumper-wires-for-breadboard-arduino-raspberry-pi-olimex-etc-544268 Jumper Wires for Breadboard, Arduino, Raspberry Pi, Olimex, etc.], Rapid Electronics</ref>
== DuPont crimp connectors ==
A DuPont crimp consists of two parts, 0.1” (2.54mm) housing and separate metal crimp terminal. Generally for jump wire size is used, with wire of 22, 24, 26, 28 or 30 AWG 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. As a general rule, you should not solder a crimp terminal.<ref>[http://www.virginiawind.com/tips/060801_02.asp Making the Connection: Solder vs. Solderless Terminals] by Jerry Sussman</ref>
