Abstract
Abstract A sleeve is fixedly fitted onto a terminal of an optical cable, and a disengagement preventing claw formed on the sleeve by cutting and raising its peripheral wall is brought into engagement with an inner surface of a recess which is formed in an inner surface of a cable receiving port of a connector housing. With this construction, the optical cable can be connected to the connector housing without using the conventional plug.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
116 words
An optical connector comprising: a sleeve fitted onto a terminal of an optical cable; a disengagement preventing claw formed on said sleeve by cutting and raising a peripheral wall of said sleeve outwardly; a connector housing including a cable receiving port into which said sleeve is inserted, said disengagement preventing claw being resiliently restored into a recess which is open to an inner surface of said cable receiving port, so that a foremost end of said disengagement preventing claw is brought into engagement with an inner surface of said recess; and wherein said recess is constructed by a through-hole which is open outwardly, and said through-hole serves as a means for disengaging said disengagement preventing claw.
Claim 2
Dependent Claim
116 words
An optical connector comprising: a sleeve fitted onto a terminal of an optical cable; a disengagement preventing claw formed on said sleeve by cutting and raising a peripheral wall of said sleeve outwardly; a connector housing including a cable receiving port into which said sleeve is inserted, said disengagement preventing claw being resiliently restored into a recess which is open to an inner surface of said cable receiving port, so that a foremost end of said disengagement preventing claw is brought into engagement with an inner surface of said recess; and wherein said recess is constructed by a through-hole which is open outwardly, and said through-hole serves as a means for disengaging said disengagement preventing claw.
Claim 3
Dependent Claim
139 words
An optical connector comprising: a sleeve mountable about an end of an optical cable; a resilient disengagement preventing claw projecting outwardly from a peripheral wall of said sleeve; a connector housing including a cable receiving port portion having an outer surface and having a cable receiving hole therein into which said sleeve is insertable, said cable receiving port portion having a through-hole which opens through both an inner surface of said cable receiving hole and said outer surface of said cable receiving port portion, said disengagement preventing claw being resiliently restored into said through-hole when said sleeve is inserted into said cable receiving hole, so that a foremost end of said disengagement preventing claw is brought into engagement with an inner surface of said through-hole; and wherein said through-hole serves as a means for disengaging said disengagement preventing claw.
Claim 4
Dependent Claim
139 words
An optical connector comprising: a sleeve mountable about an end of an optical cable; a resilient disengagement preventing claw projecting outwardly from a peripheral wall of said sleeve; a connector housing including a cable receiving port portion having an outer surface and having a cable receiving hole therein into which said sleeve is insertable, said cable receiving port portion having a through-hole which opens through both an inner surface of said cable receiving hole and said outer surface of said cable receiving port portion, said disengagement preventing claw being resiliently restored into said through-hole when said sleeve is inserted into said cable receiving hole, so that a foremost end of said disengagement preventing claw is brought into engagement with an inner surface of said through-hole; and wherein said through-hole serves as a means for disengaging said disengagement preventing claw.
Claim 5
Dependent Claim
17 words
An optical connector as recited in claim 2, wherein said sleeve has the optical cable mounted therein.
Claim 6
Dependent Claim
19 words
An optical connector as recited in claim 2, wherein said through-hole extends radially outwardly from said cable receiving hole.
