Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
120 words
A junction box for providing access to optical fibers for making splices therein comprising: a base and a cover defining an enclosure therewithin, each of said base and said cover having a plurality of elements providing half-cylindrical channels, the elements at the base being in facing relationship to the elements of the cover to provide a plurality of generally cylindrical passages for supporting optical fiber cables, pairs of recesses adjoining said elements in said cover and said base, and a plug of resilient material in each of said pairs of recesses, said plugs each having at least one opening therein for engagingly receiving an optical fiber cable passing in a said adjoining passage in a facing pair of said elements.
Claim 2
Dependent Claim
120 words
A junction box for providing access to optical fibers for making splices therein comprising: a base and a cover defining an enclosure therewithin, each of said base and said cover having a plurality of elements providing half-cylindrical channels, the elements at the base being in facing relationship to the elements of the cover to provide a plurality of generally cylindrical passages for supporting optical fiber cables, pairs of recesses adjoining said elements in said cover and said base, and a plug of resilient material in each of said pairs of recesses, said plugs each having at least one opening therein for engagingly receiving an optical fiber cable passing in a said adjoining passage in a facing pair of said elements.
Claim 3
Dependent Claim
28 words
The junction box of claim 1, and means extending about the periphery of said base and cover for preventing the entry of liquid therebetween into said junction box.
Claim 4
Dependent Claim
24 words
The junction box of claim 1, at least one of said base and cover providing at least one recess therein for holding spare plugs.
Claim 5
Dependent Claim
15 words
The junction box of claim 1, said cover having reinforcing structure adjacent the said plugs.
Claim 6
Dependent Claim
24 words
The junction box of claim 1, and further comprising inserts adjacent to said elements and located on the base for fixing cable connecting strips.
Claim 7
Dependent Claim
30 words
The junction box of claim 1, wherein said base is relatively shallow, and said cover is relatively deep, said cover having sloped side and end walls and a rectangular top.
Claim 8
Dependent Claim
21 words
The junction box of claim 6, and further comprising an inner frame having therein a plurality of optical fiber junction trays.
Claim 9
Dependent Claim
31 words
The junction box of claim 1, wherein at least one said plug has a plurality of openings extending therethrough for receiving a separate cable of optical fibers in each said opening.
Claim 10
Dependent Claim
35 words
The junction box of claim 8, and wherein there is provided a slit in said plug for each of said openings, each said slit extending from the exterior of said plug to a said opening.
Claim 11
Dependent Claim
19 words
The junction box of claim 1, and a slit extending from the exterior of said plug to said opening.
