Power supply connectors

These connectors are all “MATE-N-LOK” connectors from TE Connectivity. This connector family consists of housings and pins sold separately in different form factors and pin sizes. Some parts can be obtained from conrad.nl; search for MATE-N-LOK.

I got the following to work with the connectors:

TE Connectivity 163304-2 Krimpcontact MATE-N-LOK, female pin, max 15A, 17 AWG Max, 20AWG Min, min dwarsdoortsnede 0.5mm2, max 1.0mm2

The TE customer drawing for the 163304 pocket MATE-N-LOK, the female pin: 0.5 to 1.0mm2 wire, for a 2.1mm diameter pin.

The corresponding pin seems to be this:

TE Connectivity 163558-2 Krimpcontact MATE-N-LOK, 15A, max 18AWG, min 22AWG,

The matching 163558 male pin from AMP, in the metric drawing: 0.3 to 0.75mm2 wire and 1.4 to 2.4mm insulation.

A male housing that is not fully compatible but which has at least proper spacing seems to be this:

TE Connectivity 350434-1 Male behuizing-board Universal-MATE-N-LOK.
