Molex KK connector: Difference between revisions

 

==Description==

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.

Strip about 2 or 3 mm of insulation from the wire. Then with a racheting crimp tool such as the HT-225D. Place the pin into the apropriate crimp tool aperture. Squeeze the crimpers only enough to hold the pin in place. Insert about 3mm of the exposed strands into the pin. Squeeze the crimpers all the way. Release the crimpers, and pull the wire and pin out. The insulation is squeezed by the back of the pin, and the wire is squeezed in the center of the pin. This is to insure good electrical contact and a good hold on the wire. Push the wire and pin into the plastic housing, ensuring that the tab end of the pin goes the correct way into the housing, to lock into the square hole.<ref>[http://www.societyofrobots.com/electronics_wire_connector.shtml Wire Connector Tutorial], Society of Robots</ref> Using a simpler crimper such as the PA-09 will entail crimping in two steps. First to crimp the conductor then to crimp the insulation.<ref>[http://www.engineer.jp/en/products/pa09e.html How To Crimp Micro Connector Pin Finely], Universal Crimping Connector Pliers, Engineer Inc.</ref>
