Claim 1
Independent Claim
276 words
A locked connector for use in electric connectors, optical fiber connectors and the like, including receptacle means having a recetacle shell, coupling means engaging the receptacle means with relative rotations, plug shell means having a plug shell engaging the receptacle shell with relative movements in their axial directions but against relative rotation, back-up means permitting said coupling means and said plug shell means to rotatably engage with each other, and detent means for holding said receptacle means and said plug shell means in their fitted position and permitting said receptacle means and said plug shell means to disengage from the fitted position by rotating said coupling means relative to said plug shell means with a force, said detent means comprising: a detent ring encircling said plug shell means and having means for rotating together with said coupling means to form a detent mechanism in connection with said plug shell, and spring means for urging said detent ring toward said plug shell; said detent ring provided with detent projections extending in an axial direction of the detent ring; said plug shell including a plug flange encircling the plug shell, said plug flange being formed with a plurality of detent recesses for receiving said detent projections of said detent ring to form said detent means; said plug flange provided with surfaces in opposition to said detent ring, said surfaces each having a mid-portion between said adjacent detent recesses and having a progressively decreased thickness from said mid-portion to the adjacent detent recesses to form a plurality of circular surfaces about the circumference of the plug flange, said detent recesses located at the bottoms of said circular arc surface.
Claim 2
Dependent Claim
276 words
A locked connector for use in electric connectors, optical fiber connectors and the like, including receptacle means having a recetacle shell, coupling means engaging the receptacle means with relative rotations, plug shell means having a plug shell engaging the receptacle shell with relative movements in their axial directions but against relative rotation, back-up means permitting said coupling means and said plug shell means to rotatably engage with each other, and detent means for holding said receptacle means and said plug shell means in their fitted position and permitting said receptacle means and said plug shell means to disengage from the fitted position by rotating said coupling means relative to said plug shell means with a force, said detent means comprising: a detent ring encircling said plug shell means and having means for rotating together with said coupling means to form a detent mechanism in connection with said plug shell, and spring means for urging said detent ring toward said plug shell; said detent ring provided with detent projections extending in an axial direction of the detent ring; said plug shell including a plug flange encircling the plug shell, said plug flange being formed with a plurality of detent recesses for receiving said detent projections of said detent ring to form said detent means; said plug flange provided with surfaces in opposition to said detent ring, said surfaces each having a mid-portion between said adjacent detent recesses and having a progressively decreased thickness from said mid-portion to the adjacent detent recesses to form a plurality of circular surfaces about the circumference of the plug flange, said detent recesses located at the bottoms of said circular arc surface.
Claim 3
Dependent Claim
46 words
A locked connector as set forth in claim 1, wherein said detent projections of the detent ring are two and located in diametrically opposed poitions, and said detent recesses of the plug flange are four and located at four positions equally spaced on the plug flange.
Claim 4
Dependent Claim
41 words
A locked connector as set forth in claim 2, wherein said detent ring is bent to form an angle about a line connecting said tow detent projections to have a springiness, thereby integtally forming said detent ring and said spring means.
Claim 5
Dependent Claim
33 words
A locked connector as set forth in claim 1, wherein said detent ring is provided with rotatable bushes supported by detent bush pins provided on the detent ring to form said detent projections.
Claim 6
Dependent Claim
35 words
A locked connector as set forth in claim 1, wherein said spring means for urging said detent ring toward said plug shell is a waved spring ring located in close proximty of said detent ring.
