Abstract
Abstract The invention relates to optical fibre telecommunication engineering. A connection support for optical fibres has a stand one of whose faces has a grid of parallel rectilinear grooves each arranged for accomodating the ends of two optical fibres placed end to end with a view to connecting them together. The middle part of each groove in which is effected the transition between the fibres being formed by an insert in the stand in the shape of a comb and the stand is divided into two halves along a mid plane perpendicular to the grid of grooves.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
107 words
A connection support for optical fibres comprising a stand having a working surface, in which there is a grid of parallel rectilinear grooves, each arranged for accommodating the ends of two optical fibres placed end-to-end with a view to connecting them together, wherein the transition between the two optical fibres to be connected together is effected in a part of each groove, said part being in the form of an insert which is constituted by a comb received in a slot formed in the stand along a plane perpendicular to the network of grooves, and having gaps between its teeth which extend the line of the grooves.
Claim 2
Dependent Claim
107 words
A connection support for optical fibres comprising a stand having a working surface, in which there is a grid of parallel rectilinear grooves, each arranged for accommodating the ends of two optical fibres placed end-to-end with a view to connecting them together, wherein the transition between the two optical fibres to be connected together is effected in a part of each groove, said part being in the form of an insert which is constituted by a comb received in a slot formed in the stand along a plane perpendicular to the network of grooves, and having gaps between its teeth which extend the line of the grooves.
Claim 3
Dependent Claim
19 words
A connection support according to claim 1, including means for adjusting the height of the comb inside the slot.
Claim 4
Dependent Claim
100 words
A connection support according to claim 2, wherein said means for adjusting the height of the comb inside the slot include: two draw bolts housed in bores provided in the stand on either side of the slot perpendicularly to the grid of grooves, each having a head bearing on a shoulder set in the working surface of the stand and screwing into tapped holes formed in tabs projecting laterally from the comb; and two compression springs, each installed on the shank of a bolt and pressing on one side against the stand and on the other side on the tabs.
Claim 5
Dependent Claim
46 words
A connection support according to claim 1, wherein the stand is divided into two halves along a or the said plane perpendicular to the grooves intersecting said insert, said two halves of the stand having means for their centering and positioning in relation to each other.
Claim 6
Dependent Claim
105 words
A connection support according to claim 1, wherein the stand has parallel slots which are cut perpendicular to the network of grooves and which divide said network into several zones: two end zones which are situated at the ends of the grooves and in which the grooves have a semi-circular transversal profile; two intermediate zones which are delimited by the slots and in which the grooves have a V-shaped transversal profile; and two central zones situated on either side of the middle portions of the grooves in which the grooves keep a V-shaped profile as in the intermediate zones but with a slightly shallower depth.
