Abstract
Abstract A protective cover is provided for a standard rectangular transformer connector bar having ports for cable installation and threaded boreholes in adjacent ninety degree planes. The cover comprises a translucent housing open at one end and closed at the other with a plurality of internal aligning ribs having apertures therein which allow longitudinal passage of the connector bar therethrough. A plurality of parallel access ports through the housing extend longitudinally and are spaced from each other ninety degrees so as to be alignable with the installation ports and boreholes of the bar connector. Opposed flexible tines extend across each of the access ports from the edges thereof. The apertures in the ribs are geometrically configured so as to align the access ports with the installation ports and boreholes of the connector bar for either a right-hand or left-hand installation of the connector bar on the transformer stud.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
229 words
An insulator cover for an elongated transformer bar connector having a plurality of spaced installation ports extending along the length thereof and extending therethrough at substantially right angles to the longitudinal axis of said bar connector, a plurality of internally threaded boreholes equal in number to said installation ports and extending from said ports to the exterior of said connector at substantially right angles to the axes of said ports, and a threaded borehole for a transformer stud locking screw, said cover comprising an elongated housing closed at one end and open at the other end; a plurality of first and second substantially parallel rows of longitudinally aligned spaced access ports through the wall of said housing, said first row of access ports being peripherally spaced from said second row of access ports substantially ninety degrees; the spacing between adjacent individual access ports being substantially the same as the spacing between said installation ports in said bar connector; at least one alignment rib secured to and extending transversly within the interior of said housing; aperture means in said alignment rib of a dimension to allow longitudinal passage of said connector bar therethrough while maintaining said cover in a substantially fixed position relative to said connector bar whereby said access ports will be aligned with said installation ports and boreholes in said bar connector when the cover is assembled thereon.
Claim 2
Dependent Claim
229 words
An insulator cover for an elongated transformer bar connector having a plurality of spaced installation ports extending along the length thereof and extending therethrough at substantially right angles to the longitudinal axis of said bar connector, a plurality of internally threaded boreholes equal in number to said installation ports and extending from said ports to the exterior of said connector at substantially right angles to the axes of said ports, and a threaded borehole for a transformer stud locking screw, said cover comprising an elongated housing closed at one end and open at the other end; a plurality of first and second substantially parallel rows of longitudinally aligned spaced access ports through the wall of said housing, said first row of access ports being peripherally spaced from said second row of access ports substantially ninety degrees; the spacing between adjacent individual access ports being substantially the same as the spacing between said installation ports in said bar connector; at least one alignment rib secured to and extending transversly within the interior of said housing; aperture means in said alignment rib of a dimension to allow longitudinal passage of said connector bar therethrough while maintaining said cover in a substantially fixed position relative to said connector bar whereby said access ports will be aligned with said installation ports and boreholes in said bar connector when the cover is assembled thereon.
Claim 3
Dependent Claim
24 words
