PV-Cables Tyco Solarlok Connector Female Plus #12AWG, 22.1203 Male or Female? At first glance, the distinction between male and female connectors is somewhat counter-intuitive. "Male" or "female" refers to the metal pins within the connectors rather than the actual plastic housing of the connectors. The housing of the male connector has a large opening at the end with the actual pin inside. The connector of the female pin, however, has a long tip goes fits into male connector when the two are mated.
