Abstract
Abstract Heat-shrinkable plastic material is molded, expanded, laterally distorted and cooled to provide an insulating cover for a flagtype electrical terminal assembly having right-angle components. The cover when positioned to enclose such terminal assembly and when heated changes its shape to envelop the terminal assembly in close-fitting relationship.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
104 words
A blank for producing an insulating cover adapted to envelop an electrical terminal assembly, said blank being formed of heatshrinkable insulating material and comprising a hollow body integrally joined to an open-ended tube of smaller transverse dimension, the body having an axis offset but parallel to the axis of the tube so that portions of the outer surfaces of the body and the tube are substantially flush, the body having an end wall partially encircling the adjacent end of said tube, and the body having exposed edges defining a notch adjacent said flush portions of the body and tube, and joining said end wall.
Claim 2
Dependent Claim
104 words
A blank for producing an insulating cover adapted to envelop an electrical terminal assembly, said blank being formed of heatshrinkable insulating material and comprising a hollow body integrally joined to an open-ended tube of smaller transverse dimension, the body having an axis offset but parallel to the axis of the tube so that portions of the outer surfaces of the body and the tube are substantially flush, the body having an end wall partially encircling the adjacent end of said tube, and the body having exposed edges defining a notch adjacent said flush portions of the body and tube, and joining said end wall.
Claim 3
Dependent Claim
114 words
A blank for producing an insulating cover to protect an electrical terminal assembly, said blank being formed of heat-shrinkable insulating material and comprising a hollow cylindrical body integrally joined to an open-ended cylindrical tube, the outer diameter of the body being greater than the outer diameter of the tube, the axis of the body being offset but parallel to the axis of the tube so that portions of the outer surfaces of the body and the tube are substantially flush, the body having an end wall partially encircling said tube, and the body having exposed curved edges defining a notch adjacent said flush portions of the body and tube, and joining said end wall.
Claim 4
Dependent Claim
114 words
A blank for producing an insulating cover to protect an electrical terminal assembly, said blank being formed of heat-shrinkable insulating material and comprising a hollow cylindrical body integrally joined to an open-ended cylindrical tube, the outer diameter of the body being greater than the outer diameter of the tube, the axis of the body being offset but parallel to the axis of the tube so that portions of the outer surfaces of the body and the tube are substantially flush, the body having an end wall partially encircling said tube, and the body having exposed curved edges defining a notch adjacent said flush portions of the body and tube, and joining said end wall.
Claim 5
Independent Claim
82 words
The method of producing an insulating cover for an electrical terminal assembly having a metal tab projecting laterally from a wire-receiving socket, said method including the following steps: molding a blank of heat-shrinkable insulating material, said blank comprising a hollow body joined to an offset tube of smaller transverse dimension, heating the blank, expanding the tube to approximately the same transverse size as the body, deforming the expanded tube while heated to form a laterally extending open pocket, and cooling the blank.
Claim 6
Independent Claim
82 words
The method of producing an insulating cover for an electrical terminal assembly having a metal tab projecting laterally from a wire-receiving socket, said method including the following steps: molding a blank of heat-shrinkable insulating material, said blank comprising a hollow body joined to an offset tube of smaller transverse dimension, heating the blank, expanding the tube to approximately the same transverse size as the body, deforming the expanded tube while heated to form a laterally extending open pocket, and cooling the blank.
Claim 7
Independent Claim
145 words
The method of producing an insulating cover for an electrical terminal assembly having a metal tab projecting laterally from a wire-receiving socket, said method including the following steps: molding a blank of heat-shrinkable insulating material, said blank comprising a hollow body integrally joined to an open-ended tube of smaller transverse dimension, the body having an axis offset but parallel to the axis of the tube so that portions of the outer surfaces of the body and the tube are substantially flush, the body having an end wall partially encircling said tube and having exposed edges defining a notch adjacent said flush portions of the body and tube, heating the blank, expanding the tube to approximately the same transverse size as the body, deforming the expanded tube in the region of the notch while heated to form a laterally extending open pocket, and cooling the blank.
Claim 8
Independent Claim
145 words
The method of producing an insulating cover for an electrical terminal assembly having a metal tab projecting laterally from a wire-receiving socket, said method including the following steps: molding a blank of heat-shrinkable insulating material, said blank comprising a hollow body integrally joined to an open-ended tube of smaller transverse dimension, the body having an axis offset but parallel to the axis of the tube so that portions of the outer surfaces of the body and the tube are substantially flush, the body having an end wall partially encircling said tube and having exposed edges defining a notch adjacent said flush portions of the body and tube, heating the blank, expanding the tube to approximately the same transverse size as the body, deforming the expanded tube in the region of the notch while heated to form a laterally extending open pocket, and cooling the blank.
Claim 9
Dependent Claim
83 words
A pre-stressed insulating cover for a flag-type electrical terminal, the cover being formed of heat-shrinkable tubular plastic material having a configuration comprising walls forming an open ended tubular portion having a laterally extending lip at one side and an axially extendinG projection at the other side, said lip and projection defining an open pocket with an inclined entrance opening which cover, when positioned to enclose the flag-type electrical terminal and when heated, changes its shape to envelop the flag-type terminal in close-fitting relationship.
Claim 10
Dependent Claim
83 words
A pre-stressed insulating cover for a flag-type electrical terminal, the cover being formed of heat-shrinkable tubular plastic material having a configuration comprising walls forming an open ended tubular portion having a laterally extending lip at one side and an axially extendinG projection at the other side, said lip and projection defining an open pocket with an inclined entrance opening which cover, when positioned to enclose the flag-type electrical terminal and when heated, changes its shape to envelop the flag-type terminal in close-fitting relationship.
Claim 11
Dependent Claim
94 words
A pre-stressed insulating cover for a flag-type electrical terminal, the cover being formed of heat-shrinkable tubular plastic material having a configuration comprising walls forming an open ended tubular portion having a laterally extending lip at one side and an axially extending projection at the other side, said lip and projection defining an open pocket with an inclined entrance opening the flag portion of the electrical terminal being insertable into said tubular portion of the cover through said entrance opening, said cover when heated changing its shape to envelop the electrical terminal in close-fitting relationship.
Claim 12
Dependent Claim
