Abstract
Abstract A releasable connection device for light-wave conductors disposed in concentric plug components characterized by sleeve means for centering and aligning the components with the sleeve means being either a single member having a bore for receiving the components and slots extending from each end so that the member can be constricted by locking nuts onto the components or being formed of a plurality of elements held together by ring elements with longitudinal slots so that locking nuts can collapse or constrict the elements into tight engagement to align the components disposed therein.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
168 words
A releasable connecting device for light-wave conductors disposed in concentric plug components, the device comprising sleeve means for telescopically receiving the components, said sleeve means having external threads and being provided with means for forming at least one lengthwise extending slot, said sleeve means having means for forming a bore for receiving the plug components containing the light-wave conductors and enabling axial movement of the components within the means for forming the bore, and locking nuts acting on the external threads of the sleeve means, each of said locking nuts having a surface for engaging the component and applying an axial force thereto, said threads of the sleeve means and the locking nuts being configured so that threading of the locking nuts on the external threads axially shifts the plug components into abutting relationship and then radially constricts the sleeve means to decrease the means for forming the bore to frictionally hold the plug components in an axially aligned position and pressed together to form a connection therebetween.
Claim 2
Dependent Claim
168 words
A releasable connecting device for light-wave conductors disposed in concentric plug components, the device comprising sleeve means for telescopically receiving the components, said sleeve means having external threads and being provided with means for forming at least one lengthwise extending slot, said sleeve means having means for forming a bore for receiving the plug components containing the light-wave conductors and enabling axial movement of the components within the means for forming the bore, and locking nuts acting on the external threads of the sleeve means, each of said locking nuts having a surface for engaging the component and applying an axial force thereto, said threads of the sleeve means and the locking nuts being configured so that threading of the locking nuts on the external threads axially shifts the plug components into abutting relationship and then radially constricts the sleeve means to decrease the means for forming the bore to frictionally hold the plug components in an axially aligned position and pressed together to form a connection therebetween.
Claim 3
Dependent Claim
26 words
A releasable connecting device according to claim 1, wherein the sleeve means is free of external threads in the area of the means forming said slots.
Claim 4
Dependent Claim
27 words
A releasable connecting device in accordance with claim 2, wherein the sleeve means comprises a one piece member having several slots extending axially inward from each end.
Claim 5
Dependent Claim
37 words
A releasable connecting device according to claim 1, wherein the sleeve means is formed by a pair of members having a prism-shaped cross section, said pair of members being held together by annular retaining elements assembled thereon.
Claim 6
Dependent Claim
42 words
A releasable connecting device according to claim 4, wherein each of said members of the sleeve means has a groove running along the periphery adjacent each end, and said annular retaining elements being disposed in said groove for holding the members together.
Claim 7
Dependent Claim
27 words
A releasable connecting device according to claim 1, wherein the sleeve means is formed by three longitudinal extending members, said members being held together by retaining elements.
Claim 8
Dependent Claim
29 words
A releasable connecting device according to claim 1, wherein the sleeve means comprises a one piece member being provided with several slots running axially inward from each end thereof.
Claim 9
Dependent Claim
29 words
A releasable connecting device according to claim 7, wherein the sleeve means has a cylindrical bore having a diameter somewhat smaller than the outside diameter of the plug components.
Claim 10
Dependent Claim
45 words
A releasable connecting device according to claim 1, wherein the sleeve means comprises a one piece member and is provided with slots extending inward from each end, each of said slots from one end being staggered from the slots from the other end by 90°.
Claim 11
Dependent Claim
24 words
A releasable connecting device according to claim 1, wherein the means forming longitudinal slots forms three slots staggered by 120° relative to each other.
Claim 12
Dependent Claim
22 words
A releasable connecting device according to claim 1, wherein each of the threads has an angle of the thread of approximately 90°.
Claim 13
Dependent Claim
19 words
A releasable connecting device according to claim 1, wherein the external threads are in the form of multiple threads.
