Abstract
Abstract A flexible flap, having an elastic memory, which flap is used to normally cover a lightwave connector so as to prevent laser radiation emissions from the connector. The flexible nature of the flap allows the forcible deflection thereof, so that a mating connector can be attached to the normally covered one, and yet when the mating connector is removed the flap will automatically return to the covering position. In addition to preventing the emission of laser radiations, the flap can reduce contamination materials, such as dust, from covering the end of the fiber optic material.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
210 words
Combination dust cover and radiation shield comprising, in combination: L-shaped base means including mounting means for attaching said base means to a support adjacent a cylindrical male lightwave connector means, said male connector means including at least one annular surface engaging means; and unitary L-shaped flexible shield means including first attachment means for connection to said base means at one end thereof and a cylindrical and tubular female second attachment means, having at least one interior annular surface, at the other end thereof for engagement with the male lightwave connector means, said shield means having a normal position wherein the female second attachment means covers the male lightwave connector means, said shield means also having an elastic memory so that it may be flexed out of its normal position of covering the lightwave connector means whereby a female lightwave connector may be attached to the male lightwave connector means and said shield means will return to said normal position, the application of force in line with an axis of said lightwave connector means and to said other end of said flexible shield means causing said annular surface of said shield means to interact with said male lightwave connector means to form a dust cover for said male lightwave connector means.
Claim 2
Dependent Claim
210 words
Combination dust cover and radiation shield comprising, in combination: L-shaped base means including mounting means for attaching said base means to a support adjacent a cylindrical male lightwave connector means, said male connector means including at least one annular surface engaging means; and unitary L-shaped flexible shield means including first attachment means for connection to said base means at one end thereof and a cylindrical and tubular female second attachment means, having at least one interior annular surface, at the other end thereof for engagement with the male lightwave connector means, said shield means having a normal position wherein the female second attachment means covers the male lightwave connector means, said shield means also having an elastic memory so that it may be flexed out of its normal position of covering the lightwave connector means whereby a female lightwave connector may be attached to the male lightwave connector means and said shield means will return to said normal position, the application of force in line with an axis of said lightwave connector means and to said other end of said flexible shield means causing said annular surface of said shield means to interact with said male lightwave connector means to form a dust cover for said male lightwave connector means.
Claim 3
Dependent Claim
237 words
Connector apparatus comprising, in combination: support means including shield mounting means, for attachment to a cylindrical male lightwave conductor shielding means, and lightwave transmission male connector means, wherein said male connector means includes at least one annular surface engaging means; unitary L-shaped flexible shield means including first attachment means for attachment to said shield mounting means at one end thereof and a cylindrical and tubular female second attachment means at the other end thereof, said shield means having a normal position wherein the female second attachment means covers the male lightwave connector means whereby light is prevented from being emitted from said male connector means, said shield means also having an elastic memory so that it may be flexed out of its normal position of covering the lightwave connector means whereby a female lightwave connector may be attached to the male lightwave connector means and said shield means will attempt to return to said normal position; and at least one interior annular surface means contained in said second attachment means, at said other end of said shield means, for engagement with the lightwave connector means, the application of force in line with an axis of said lightwave connector means and to said other end of said flexible shield means causing said annular surface means of said shield means to interact with said male lightwave connector means to form a dust cover for said male lightwave connector means.
Claim 4
Dependent Claim
237 words
Connector apparatus comprising, in combination: support means including shield mounting means, for attachment to a cylindrical male lightwave conductor shielding means, and lightwave transmission male connector means, wherein said male connector means includes at least one annular surface engaging means; unitary L-shaped flexible shield means including first attachment means for attachment to said shield mounting means at one end thereof and a cylindrical and tubular female second attachment means at the other end thereof, said shield means having a normal position wherein the female second attachment means covers the male lightwave connector means whereby light is prevented from being emitted from said male connector means, said shield means also having an elastic memory so that it may be flexed out of its normal position of covering the lightwave connector means whereby a female lightwave connector may be attached to the male lightwave connector means and said shield means will attempt to return to said normal position; and at least one interior annular surface means contained in said second attachment means, at said other end of said shield means, for engagement with the lightwave connector means, the application of force in line with an axis of said lightwave connector means and to said other end of said flexible shield means causing said annular surface means of said shield means to interact with said male lightwave connector means to form a dust cover for said male lightwave connector means.
Claim 5
Independent Claim
107 words
The method of shielding the output of a support mounted lightwave connector means comprising, the steps of: forming a flexible female cavity, including a least one cavity annular surface for engaging said lightwave connector means, at one end of a length of elastic memory type material; and attaching the other end of said length of elastic memory type material adjacent said support mounted lightwave connector means whereby the cavity normally covers and shields said lightwave connector means from providing light output while allowing forceable, but temporary, displacement of said cavity so that a mating lightwave connector means may be connected to said support mounted lightwave connector means.
Claim 6
Independent Claim
107 words
The method of shielding the output of a support mounted lightwave connector means comprising, the steps of: forming a flexible female cavity, including a least one cavity annular surface for engaging said lightwave connector means, at one end of a length of elastic memory type material; and attaching the other end of said length of elastic memory type material adjacent said support mounted lightwave connector means whereby the cavity normally covers and shields said lightwave connector means from providing light output while allowing forceable, but temporary, displacement of said cavity so that a mating lightwave connector means may be connected to said support mounted lightwave connector means.
Claim 7
Dependent Claim
122 words
Apparatus for shielding the output of a support mounted lightwave connector means comprising, in combination: support means; lightwave connector means mounted on said support means; a length of elastic memory type material having at one end thereof means forming a flexible female cavity, said cavity including at least one annular surface for engaging said lightwave connector means; and means for attaching the other end of said length of elastic memory type material to said support means adjacent said lightwave connector means whereby the cavity normally covers and shields said lightwave connector means from providing light output while allowing forceable, but temporary, displacement of said cavity so that a mating lightwave connector means may be connected to said support mounted lightwave connector means.
Claim 8
Dependent Claim
