Abstract
Abstract A clamp for optical fiber couplers manufacturing apparatus comprises a slotted member having a slot into which optical fibers are inserted and having an opening outwardly winder from the slot so that the optical fibers are introduced into the slot, and a pushing member movably disposed adjacent the slot for pushing the optical fibers through the opening into the slot, wherein the slotted member is away from the pushing member when the fibers are not clamped, and the slotted member is fixed at a position where the slotted member clamps the fibers.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
146 words
An apparatus for clamping a plurality of optical fibers comprising: a first Y-shaped member being shaped so as to define a first slot, an upper portion of said first slot having a larger width than a lower portion of said first slot for facilitating entry of said optical fibers into said first slot; a second Y-shaped member being shaped so as to define a second slot, an upper portion of said second slot having a larger width than a lower portion of said second slot for facilitating entry of said optical fibers into said second slot; a pushing element for pushing said at least two optical fibers into said first slot and said second slot; and moving means for simultaneously moving said first and second Y-shaped members closer to said pushing element to effect clamping and apart from said pushing means after said fibers are coupled.
Claim 2
Independent Claim
146 words
An apparatus for clamping a plurality of optical fibers comprising: a first Y-shaped member being shaped so as to define a first slot, an upper portion of said first slot having a larger width than a lower portion of said first slot for facilitating entry of said optical fibers into said first slot; a second Y-shaped member being shaped so as to define a second slot, an upper portion of said second slot having a larger width than a lower portion of said second slot for facilitating entry of said optical fibers into said second slot; a pushing element for pushing said at least two optical fibers into said first slot and said second slot; and moving means for simultaneously moving said first and second Y-shaped members closer to said pushing element to effect clamping and apart from said pushing means after said fibers are coupled.
Claim 3
Dependent Claim
48 words
A clamp as described in claim 1 wherein said upper portion of said first Y-shaped member and said upper portion of second Y-shaped member are separated, said pushing element being received between said upper member of said first Y-shaped member and-said upper portion of said second Y-shaped member.
Claim 4
Dependent Claim
29 words
A clamp as described in claim 1 wherein said pushing element has a protruding portion for engaging a region between said first Y-shaped member and said second Y-shaped member.
Claim 5
Dependent Claim
34 words
A clamp as described in claim 3 wherein said protruding portion of said pushing element engages said first and second Y-shaped members orthogonal to an alignment of said first slot and said second slot.
Claim 6
Dependent Claim
19 words
A clamp as described in claim 1 wherein said first Y-shaped member is connected to said second Y-shaped member.
Claim 7
Dependent Claim
17 words
A clamp as described in claim 1 wherein said first slot is aligned with said second slot.
Claim 8
Independent Claim
110 words
A method for clamping a plurality of optical fibers between at least two Y-shaped members and a pushing element, each Y-shaped member being shaped so as to define a slot having a narrow region and a wide region, said method comprising the steps of: simultaneously moving said Y-shaped members closer to said pushing element to collect optical fibers in said Y-shaped members; receiving optical fibers in said wide regions of said slots within said Y-shaped members; and inserting said pushing element into an area between said Y-shaped members which is orthogonal to said slots to clamp said optical fibers in said narrow regions of said slots in said Y-shaped members.
Claim 9
Independent Claim
110 words
A method for clamping a plurality of optical fibers between at least two Y-shaped members and a pushing element, each Y-shaped member being shaped so as to define a slot having a narrow region and a wide region, said method comprising the steps of: simultaneously moving said Y-shaped members closer to said pushing element to collect optical fibers in said Y-shaped members; receiving optical fibers in said wide regions of said slots within said Y-shaped members; and inserting said pushing element into an area between said Y-shaped members which is orthogonal to said slots to clamp said optical fibers in said narrow regions of said slots in said Y-shaped members.
