The Molex KK '''crimp connector''' is used in synthesizer by [[CGS]], [[Cyndustries]], [[EFM]], [[Encore Electronics]], [[Metalbox]], [[Oakley Sound Systems]] and [[Synthesis Technology]].<ref>[http://search.retrosynth.com/synth-diy/search/lookit.cgi?-v0503.816 Re: [sdiy] Blacet/Paia power header part number?] by Cynthia Webster, 21 Mar 2005</ref>

The ''header'' with pins is usually on the [[PCB]]. Inside the ''housing'' which mates with it, a metal sleeve is secured each conductor in two places, on the wire and on its insulator. Creating a ''gas-tight'' connection between the wire and terminal pin, prohibiting corrosion and the latter forming a ''strain relief'', providing additional resistance to mechanical stress.<ref>Molex Connectors Explained, as used in Pinball.

Molex KK housings mate with Molex KK headers on the [[PCB]]. The Molex headers look very similar to the [[MTA]] ones by TE AMP, but they are not the same. Do not try an force a Molex KK housing onto a MTA header or vice versa.<ref name="oakley">Oakley Sound Systems, [http://www.oakleysound.com/construct.pdf Construction Guide] by Tony Allgood, v1.2.4, 24th September 2013, p. 27</ref>
== Crimping ==
A Molex KK socket consists of two parts, a housing and metal crimp terminals. The terminals are bought separately. Generally two different sizes are in use, 0.1” (2.54mm) for signal connections and 0.156" (3.96mm) for power distribution. For 0.100" use wire of 22, 24, 26, 28 or 30 [[AWG]] with 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, may reduce electrical conductivity, and may 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>
