An example waveguide connector is for making a blind-mate electrical connection between a first waveguide and a second waveguide. The waveguide connector includes a male part connected to the first waveguide, where the first waveguide includes a first conductive channel, and a female part connected to the second waveguide, where the second waveguide includes a second conductive channel. The female part includes a receptacle into which the male part slides to create the blind-mate electrical connection between the first conductive channel and the second conductive channel. A self-alignment feature is on at least one of the male part or the female part. The self-alignment feature is configured to guide the male part into the receptacle while correcting for misalignment of the male part and the female part.
