Abstract

Abstract The invention relates to a connector for fiber optics, having two ferrules mounted on the end of each of the fibers to be connected, each having a bore into which the fiber optic can be inserted loosely and fixed in place such that its end coincides with the end of the ferrule, and a female reconstitution coupling having a longitudinal bore to support and align the two ferrules face to face, and longitudinal pressure means to thrust each of the ferrules toward the other, characterized by the fact that it includes a separator (11) of resilient plastic material having a refractive index equal to or close to that of the core of the fibers (8) to be connected, the said separator having, prior to its installation, a thickness at least equal to the gap (e) between the ends of the confronting fibers once the connection is made, the said separator (1) being made integral with a sleeve (12) adapted to be positioned and held inside of the female reconstitution coupling.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 175 words
A connector for fiber optics having two ferrules mounted on the end of each of the fibers to be connected, each having a bore into which the fiber optic may be inserted loosely and fixed in place such that its end coincides with the end of the ferrule, and a female reconstitution coupling having a longitudinal bore for supporting and aligning the two confronting ferrules, and longitudinal pressure means to thrust each of the ferrules toward the other, characterized by the fact that the connector substantially includes a separator (11) of resilient plastic material having a refractive index equal to or close to that of the core of the fibers (8) to be connected, said separator having, prior to its installation, a thickness at least equal to the gap (e) between the ends of the confronting fibers once the connection is made, said separator being integral with a sleeve (12) adapted to be positioned and held inside of a female reconstitution coupling whereby said separator may be removed and replaced without damage to said fibers.
Claim 2
Dependent Claim 175 words
A connector for fiber optics having two ferrules mounted on the end of each of the fibers to be connected, each having a bore into which the fiber optic may be inserted loosely and fixed in place such that its end coincides with the end of the ferrule, and a female reconstitution coupling having a longitudinal bore for supporting and aligning the two confronting ferrules, and longitudinal pressure means to thrust each of the ferrules toward the other, characterized by the fact that the connector substantially includes a separator (11) of resilient plastic material having a refractive index equal to or close to that of the core of the fibers (8) to be connected, said separator having, prior to its installation, a thickness at least equal to the gap (e) between the ends of the confronting fibers once the connection is made, said separator being integral with a sleeve (12) adapted to be positioned and held inside of a female reconstitution coupling whereby said separator may be removed and replaced without damage to said fibers.
Claim 3
Dependent Claim 19 words
A connector according to claim 1, characterized by the fact that the separator (11) is made of silicone elastomer.
Claim 4
Dependent Claim 26 words
A connector according to claim 1, characterized by the fact that the exterior wall (14) of said sleeve (12) has a convex, curved or biconical section.
Claim 5
Dependent Claim 74 words
A connector according to claim 1 in which there is provided an abutment body held in the longitudinal bore of the female coupling and having an axial bore into which protuberances at the ends of the ferrules are introduced and with the end of which the ends of the fibers coincide, characterized by the fact that the said sleeve (12) is force-fitted into the said axial bore (4) of the said abutment body (3).
