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, a housing and metal crimp terminal. The terminals are bought separately. Generally for jump wires 0.1” (2.54mm) 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> For 0.156" use wire of 18, 20, 22 or 24 AWG, with a maximum diameter of 2.79mm.<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>
