Abstract
Abstract A method and apparatus for connecting individual light waveguides characterized by providing a splicing element holder, a pair of spaced waveguide clamping devices which are spaced from the holder, securing a splicing element having a longitudinal extending centering groove with the base in the holder with the groove opening toward the clamping devices, clamping a light waveguide in each clamping device with an end portion of the waveguide extending toward the splicing element at an acute angle, moving either the holder toward the pair of clamping devices or the pair of clamping devices toward the holder to insert the ends of the pair of waveguides into the centering groove of the splicing element, to bring the end faces of the pair of waveguides into contact with each other, and to cause the end portions of the waveguides to bend and to move into the centering groove for alignment of the end portions and subsequently securing the aligned end portions in the splicing device.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
172 words
A method of connecting a pair of individual light waveguides in end-to-end light transmitting relationship in a splicing element, said method comprising providing a splicing element holder and a pair of spaced waveguide clamping devices which are spaced from the holder; securing a splicing element having a longitudinal extending centering groove with a base in the holder with the groove opening toward the pair of spaced clamping devices clamping a light waveguide in each clamping device with an end portion of each waveguide extending toward the base of the centering groove at an acute angle; creating relative movement between the holder and the pair of clamping devices to insert the end of each of the waveguides into the centering groove of the splicing element, to bring the end faces of the pair of waveguides in contact with each other and to cause the end portions of the waveguides to bend and to move into the centering groove for axial alignment therein; and then securing the aligned end portions in the splicing element.
Claim 2
Independent Claim
172 words
A method of connecting a pair of individual light waveguides in end-to-end light transmitting relationship in a splicing element, said method comprising providing a splicing element holder and a pair of spaced waveguide clamping devices which are spaced from the holder; securing a splicing element having a longitudinal extending centering groove with a base in the holder with the groove opening toward the pair of spaced clamping devices clamping a light waveguide in each clamping device with an end portion of each waveguide extending toward the base of the centering groove at an acute angle; creating relative movement between the holder and the pair of clamping devices to insert the end of each of the waveguides into the centering groove of the splicing element, to bring the end faces of the pair of waveguides in contact with each other and to cause the end portions of the waveguides to bend and to move into the centering groove for axial alignment therein; and then securing the aligned end portions in the splicing element.
Claim 3
Dependent Claim
43 words
A method according to claim 1, wherein the step of creating relative movement between the holder and the pair of clamping devices comprise maintaining the splicing element holder in a stationary position and moving the pair of clamping devices toward the stationary holder.
Claim 4
Dependent Claim
46 words
A method according to claim 1, wherein the step of creating relative movement between the holder and the pair of clamping devices comprise maintaining each of the pair of clamping devices in a stationary position and moving the splicing element holder toward the stationary clamping devices.
Claim 5
Dependent Claim
56 words
A method according to claim 1, which includes subsequent to clamping the light waveguide in each of the clamping devices and prior to the step of creating relative movement removing a protective casing from each of the end portions of the clamped waveguide and subsequently cutting the exposed portion of the waveguides to a desired length.
Claim 6
Dependent Claim
40 words
A method according to claim 1, wherein subsequent to the step of clamping a waveguide in each of the clamping devices and prior to the step of creating relative movement cutting each of the end portions to a prerequisite length.
Claim 7
Dependent Claim
23 words
A method according to claim 1, wherein the step of securing comprises deforming the splicing element into gripping engagement on the aligned waveguides.
Claim 8
Dependent Claim
31 words
A method according to claim 1, wherein the step of securing comprises applying an adhesive material for cementing the end portions of the pair of aligned waveguides in the splicing element.
Claim 9
Dependent Claim
93 words
A method according to claim 1, wherein the step of creating relative movement between the holder and pair of clamping devices comprises subsequentially decreasing the distance between the holder and pair of clamping devices to insert the end of the waveguide in the centering groove, then moving the clamping devices toward each other to bring the end of the waveguide into contact, and then moving the holder and pair of clamping devices to further decrease the distance therebetween and to cause the bending of the end portions of the waveguides into axial alignment.
Claim 10
Independent Claim
133 words
An apparatus for forming a connection of a pair of individual light waveguides in end-to-end light transmitting relationship in a splicing element, said apparatus comprising a splicing element holder, a pair of clamping devices, each of said pair of clamping devices holding a single waveguide with an end portion extending at an acute angle to a splicing element with a centering groove supported in the splicing element holder; means for creating relative movement between the pair of clamping devices and the splicing element holder; and means for securing the aligned waveguides in the splicing element so that after the ends of the waveguides are inserted in the centering groove, moved into contact and adjacent end portions are bent into axial alignment, the waveguides and splicing element are secured together to complete the connection.
Claim 11
Independent Claim
133 words
An apparatus for forming a connection of a pair of individual light waveguides in end-to-end light transmitting relationship in a splicing element, said apparatus comprising a splicing element holder, a pair of clamping devices, each of said pair of clamping devices holding a single waveguide with an end portion extending at an acute angle to a splicing element with a centering groove supported in the splicing element holder; means for creating relative movement between the pair of clamping devices and the splicing element holder; and means for securing the aligned waveguides in the splicing element so that after the ends of the waveguides are inserted in the centering groove, moved into contact and adjacent end portions are bent into axial alignment, the waveguides and splicing element are secured together to complete the connection.
Claim 12
Dependent Claim
36 words
An apparatus according to claim 9, wherein the means for securing comprises means for applying a dose of adhesive material to the aligned waveguides in the splicing device so that the aligned waveguides are secured therein.
