Solar connector consists of a plug and socket design. Oddly, the plugs and sockets are placed inside plastic shells, the plug is inside a
cylindrical shell that looks like a female connector but it is actually a male, and the socket is inside a square probe that looks male but is actually female.
The female connector has two plastic fingers which is pressed toward the central probe slightly so that
it gets inserted into the holes in the front of the male connector. When the two are pushed together,
the fingers slide down the holes until they reach a notch cut into the side of the male connector, where they pop outward to lock the two together.
