Patent number: 11428872Abstract: An optical connector includes a first attachment area for receiving and permanently attaching to an optical waveguide. A light coupling unit is disposed and configured to move translationally and not rotationally within the housing of the connector. The light coupling unit includes a second attachment area for receiving and permanently attaching to an optical waveguide received and permanently attached at the first attachment area. The light coupling unit also includes light redirecting surface. The light redirecting surface is configured such that when an optical waveguide is received and permanently attached at the first and second attachment areas, the light redirecting surface receives and redirects light from the optical waveguide. The optical waveguide limits, but does not prevent, a movement of the light coupling unit within the housing.Type: GrantFiled: May 10, 2021Date of Patent: August 30, 2022Assignee: 3M Innovative Properties CompanyInventors: Terry L.
