Which connector type is this?
The SAE DC connector is hermaphroditic which means there is no difference between the plug and socket.

Searching for "SAE Right angle connector" brings up other sellers of the product you linked to, but does not shed any light on the source of the connector itself.

As it seems to be an injection moulded part, there is a good chance you cannot buy these off the shelf - the whole assembly is moulded in the factory. Unless a solder cup version exists, your best bet is to find a cheap supplier of the cables and cut them to length.
