Abstract
Abstract A device for forming a detachable connection between a waveguide and another optical component or waveguide characterized by a coupling section and at least one plug. Each plug comprises a base member having a trough-shaped cross section with a pair of spaced, upstanding shanks at one end of the base member and a flap member secured to the base member with a portion covering an opening between the shanks and movable therefrom. Each plug member receives at least one waveguide and engages the protective sheathing so that the waveguide is secured therein with a free end of the waveguide, which end has the protective sheath removed, extending between the spaced shanks at the one end. The coupling section has means for guiding a plug in a linear path as it is inserted in the coupling section and means forming a centering groove which extends into the path of each plug at an acute angle thereto so that as the plug is inserted in the coupling section, the free end of each waveguide, which is secured in the plug, is received in the centering groove and deflected thereby to move therealong to a position for forming an optical contact with the optical component. If the optical component is a transmission or reception diode, the coupling section has a plane surface extending perpendicular to the axis of the centering groove so that when the optical component is held on the plane surface, the waveguide will be perpendicular to the active surface and contact it to the same optical axis. When the optical component is another waveguide, the device will have a pair of means for guiding each of the plugs with the means forming the centering groove disposed there-between and extending at an acute angle to both guide means.

Total Claims: 11
Claim 1
Independent Claim
273 words
A device for detachably connecting at least one light waveguide having a protective sheathing to another light waveguide, said device comprising a coupling section and a pair of plugs, each of said pair of plugs comprising a base member having a trough-shaped cross section with a pair of spaced, upstanding shanks at one end of the base member and a flap member secured to said base member with a portion covering the space between the pair of shanks at said one end of the base member and being movable from a position covering said shanks, each of said plugs receiving at least one light waveguide and engaging the protective sheathing so that the waveguide is secured therein with a free end of the waveguide, which end has the protective sheathing removed, extending between the spaced shanks at said one end of the base member, said coupling section having a pair of separate means for guiding a plug in a linear path as it is inserted into the coupling section, each of said separate means for guiding being a plug guide having a trough-like cross section for slidably receiving the plug, and means forming a centering groove being disposed between the pair of plug guides and extending into the path of each plug at an acute angle thereto so that as each of the plugs is inserted into the coupling section, the free end of each of the waveguides secured therein is received in a centering groove and deflected thereby to move therealong to a position for forming an optical contact with a waveguide carried by the other plug of the pair of plugs.
Claim 2
Independent Claim
273 words
A device for detachably connecting at least one light waveguide having a protective sheathing to another light waveguide, said device comprising a coupling section and a pair of plugs, each of said pair of plugs comprising a base member having a trough-shaped cross section with a pair of spaced, upstanding shanks at one end of the base member and a flap member secured to said base member with a portion covering the space between the pair of shanks at said one end of the base member and being movable from a position covering said shanks, each of said plugs receiving at least one light waveguide and engaging the protective sheathing so that the waveguide is secured therein with a free end of the waveguide, which end has the protective sheathing removed, extending between the spaced shanks at said one end of the base member, said coupling section having a pair of separate means for guiding a plug in a linear path as it is inserted into the coupling section, each of said separate means for guiding being a plug guide having a trough-like cross section for slidably receiving the plug, and means forming a centering groove being disposed between the pair of plug guides and extending into the path of each plug at an acute angle thereto so that as each of the plugs is inserted into the coupling section, the free end of each of the waveguides secured therein is received in a centering groove and deflected thereby to move therealong to a position for forming an optical contact with a waveguide carried by the other plug of the pair of plugs.
