Cutout cover
A fuse cutout assembly cover including an insulator cover end for positioning over a cutout assembly insulator and including a shield end for shielding a cutout upper contact assembly. The insulator cover is constructed to receive a variety of insulator and cutout assembly configurations.
1 . A fuse cutout cover for use with fuse cutout assemblies having insulators of different sizes and configurations, the fuse cutout assemblies each further including a fuse and an upper contact assembly for engaging an upper end of the fuse, the cover comprising:
a contact assembly shield configured for shielding the upper contact assembly; and
an insulator cover configured for covering at least an upper end of the insulator, the insulator cover comprising a hollow body having a central longitudinal axis and including a first side wall having a first height, a second side wall disposed above the first side wall, the second side wall having a second height and at least a portion of the second side wall being located inwardly of the first side wall toward the longitudinal axis of the hollow body, a first top wall extending between the first side wall and the second side wall at a top of the first side wall, the first top wall being discontinuous with the first side wall and the second side wall, and a third side wall disposed above the second side wall, the third side wall having a third height and at least a portion of the third side wall being located inwardly of the second side wall toward the longitudinal axis of the hollow body, and a second top wall extending between the second side wall and the third side wall at a top of the second side wall, the second top wall being discontinuous with the second side wall and the third side wall.
2 . A fuse cutout cover as set forth in claim 1 wherein at least a majority of the second side wall is located inwardly of the first side wall toward the longitudinal axis of the hollow body.
3 . A fuse cutout cover as set forth in claim 2 wherein at least a majority of the third side wall is located inwardly of the second side wall toward the longitudinal axis of the hollow body.
4 . A fuse cutout cover as set forth in claim 1 , further comprising a first transverse wall extending from a top of the first side wall forming a shoulder on the hollow body.
5 . A fuse cutout cover as set forth in claim 2 , further comprising a second transverse wall extending from a top of the second side wall.
6 . A fuse cutout cover as set forth in claim 5 , further comprising a third transverse wall extending from a top of the third side wall and defining an opening.
7 . A fuse cutout cover as set forth in claim 4 , further comprising a split formed in the first, second and third side walls, the split permitting the insulator cover to be resiliently deformed to receive portions of the cutout assembly into the insulator cover.
8 . A fuse cutout cover as set forth in claim 1 , wherein the contact assembly shield and the insulator cover are formed from a single piece of material.
9 . A fuse cutout cover as set forth in claim 1 , wherein the first side wall comprises a generally cylindrical wall.
10 . A fuse cutout cover as set forth in claim 9 , wherein the second side wall comprises a non-cylindrical wall.
11 . A fuse cutout cover as set forth in claim 10 , wherein the third side wall comprises a non-cylindrical wall.
12 . A fuse cutout cover for use with fuse cutout assemblies having insulators of different sizes and configurations, the fuse cutout assemblies each further including a fuse and an upper contact assembly for engaging an upper end of the fuse, the cover comprising:
a contact assembly shield configured for shielding the upper contact assembly; and
an insulator cover having a longitudinal axis extending through a center of the insulator cover, the insulator cover being configured for covering at least an upper end of the insulator, the insulator cover comprising a hollow body including a first side wall, a second side wall disposed above the first side wall and a third side wall disposed above the second side wall, the second side wall being shaped to define a first space having a first cross sectional area, and a second space having a second cross sectional area smaller than the first cross sectional area, the longitudinal axis passing through the second space and the first space being located radially outward from the longitudinal axis.
13 . The fuse cutout cover as set forth in claim 12 wherein the second side wall defines a third space having a third cross sectional area smaller than the second cross sectional area.
14 . The fuse cutout cover as set forth in claim 13 wherein the second side wall includes a first side wall section having a serpentine shape.
15 . The fuse cutout cover as set forth in claim 14 wherein the second side wall further includes a second side wall section opposite the first side wall section, the second side wall section having a serpentine shape.
16 . The fuse cutout cover as set forth in claim 15 wherein the second side wall further includes a third side wall section extending between the first and second side wall sections of the second side wall, the third side wall section having an arcuate shape.
17 . The fuse cutout cover as set forth in claim 16 wherein the second side wall further includes a fourth side wall section located on an opposite end of the first side wall section from the third side wall section.
18 . The fuse cutout cover as set forth in claim 12 wherein the first side wall is generally cylindrical and the second side wall is non-cylindrical.
19 . A fuse cutout cover as set forth in claim 12 , further comprising a continuous slit extending through the first side wall, second side wall and third side wall, the slit permitting the insulator cover to be resiliently deformed to receive portions of the cutout assembly into the insulator cover.
20 . A fuse cutout cover as set forth in claim 19 wherein the slit separates the first side wall section of the second side wall from the second side wall section of the second side wall.
