Abstract From the Canadian patent

A device or appliance comprising a light waveguide plug connector is composed of a pin seated resiliently and with play in a socket. Both the pin and socket have cylindrical portions and conical end portions, one of the pins and socket has an intermediate tapering portion with a taper substantially less than the taper of the conical end portion. The slightly tapered intermediate portion will facilitate the plugging in of the pin into the socket, even given a radial offset of the axis of the socket and the pin to each other.
