Abstract
Abstract A stiff resilient segmented polymeric plastic sheet useful for forming an enclosure about a cable splice or termination. The sheet is grooved to reduce its thickness along narrow linear intersecting latticed strips which define rectangular and triangular patterns in the sheet. The sheet can be easily cut and folded along the narrow strips to form hollow enclosures of various sizes and shapes.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
77 words
An enclosure attached to an electrical cable and extending around a splice or termination in the cable, said enclosure comprising a stiff, resilient, polymeric sheet having latticed grooves on one surface to reduce its thickness and define intersecting sets of spaced parallel narrow strips connecting segments of the sheet, said sheet being bent along some of said strips to shape the enclosure, means attaching edges of the sheet together and means attaching said sheet to the cable.
Claim 2
Dependent Claim
77 words
An enclosure attached to an electrical cable and extending around a splice or termination in the cable, said enclosure comprising a stiff, resilient, polymeric sheet having latticed grooves on one surface to reduce its thickness and define intersecting sets of spaced parallel narrow strips connecting segments of the sheet, said sheet being bent along some of said strips to shape the enclosure, means attaching edges of the sheet together and means attaching said sheet to the cable.
Claim 3
Dependent Claim
77 words
An enclosure attached to an electrical cable and extending around a splice or termination in the cable, said enclosure comprising a stiff, resilient, polymeric sheet having latticed grooves on one surface to reduce its thickness and define intersecting sets of spaced parallel narrow strips connecting segments of the sheet, said sheet being bent along some of said strips to shape the enclosure, means attaching edges of the sheet together and means attaching said sheet to the cable.
Claim 4
Dependent Claim
77 words
An enclosure attached to an electrical cable and extending around a splice or termination in the cable, said enclosure comprising a stiff, resilient, polymeric sheet having latticed grooves on one surface to reduce its thickness and define intersecting sets of spaced parallel narrow strips connecting segments of the sheet, said sheet being bent along some of said strips to shape the enclosure, means attaching edges of the sheet together and means attaching said sheet to the cable.
Claim 5
Dependent Claim
19 words
An enclosure according to claim 1, further including an electrically insulating resinuous composition around the splice within the enclosure.
Claim 6
Dependent Claim
64 words
An enclosure according to claim 2, wherein the sheet is of polypropylene having a thickness through the segments of between about 0.04 to 0.10 inch, and a thickness through the strips of less than about 0.03 inch, the spacing between the strips of said first set is about 0.5 inch and the spacing between the strips of said second set is about 3 inches.
Claim 7
Dependent Claim
74 words
An enclosure according to claim 3, wherein said intersecting sets of strips include a first longitudinally extending set; a second set perpendicular to and intersecting the first set to define a rectangular pattern; and third and fourth sets oblique to each other, intersecting at every second intersection of the first and second sets, and extending diagonally of the rectangular pattern so that the shape of each segment is right triangular along said one surface.
Claim 8
Dependent Claim
57 words
An enclosure according to claim 1, wherein said sets of strips include a lonitudinally extending first set, and two additional sets having strips of equal spacing intersecting each other along the strips of the first set to form therewith an included angle of less than 45* to define segments having a triangular shape along said one surface.
