US Patent:

20220317386, Oct 6, 2022

Filed:

Jun 21, 2022

Appl. No.:

17/844909

Inventors:

- St. Paul MN, US
Terry L. Smith - Roseville MN, US
Alexander R. Mathews - Austin TX, US
James M. Nelson - Lino Lakes MN, US

International Classification:

G02B 6/38
G02B 6/32

Abstract:

An optical cable subassembly includes one or more optical waveguides, at least light coupling unit comprising a first attachment area permanently attached to the optical waveguides, and at least one cable retainer comprising a second attachment area permanently attached to the optical waveguides and adapted to be installed in a housing. A length of the optical waveguides between the first attachment area and the second attachment area allows a bend in the optical waveguides that provides a predetermined mating spring force at a predetermined angle of the light coupling unit when installed in the housing.

International Classification:

G02B 6/38
G02B 6/40

Abstract:

A connector is disclosed that includes a housing and first and second attachment areas located in the housing and spaced apart from each other along the mating direction of the connector. The second, but not the first, attachment area is designed to move relative to the housing. The connector further includes an optical waveguide that is permanently attached to, and under a first bending force between, the first and second attachment areas. The connector also includes a light coupling unit located in the housing for receiving light from the optical waveguide and transmitting the received light to a mating connector along a direction different than the mating direction of the connector. The mating of the connector to the mating connector causes the optical waveguide to be under a greater second bending force between the first and second attachment areas.

International Classification:

G02B 6/38

Abstract:

A modular optical connector includes a plurality of coupled optical ferrule support modules. Each optical ferrule support module comprises module connecting features configured to couple each ferrule support module with one or more neighboring ferrule support modules of the plurality of ferrule support modules. One or more optical ferrules are disposed and configured to rotate within the ferrule support module. Each optical ferrule includes a first attachment area configured to attach to one or more optical waveguides. One or more passageways are disposed within the ferrule support module. Each passageway is configured to receive the one or more optical waveguides. The passageway comprises a second attachment area configured to attach to the optical waveguides that are attached to the optical ferrule at the first attachment area. The passageway is dimensioned to constrain the optical waveguides to bend within the housing between the first attachment area and the second attachment area.

Abstract:

A hybrid connector includes a connector housing, one or more first connection elements configured to transfer a first type of energy or a fluid, and one or more second connection elements configured to transfer a second type of energy, different from the first type of energy, or the fluid. The first connection elements are rotationally fixed and the second connection elements are configured to rotate around an axis that is substantially perpendicular to a mating axis of the housing
