Abstract

Abstract A terminal for a watthour meter employs an offset portion internal to the watthour meter for disposing contacting surfaces for connection to current-coil conductors at four different transverse locations. Formation of the offset produces an under surface used as one element for capturing and applying compression force to a washer over a terminal gasket. A projection from the opposite surface of the terminal forms a bearing surface as the other element for applying compression force to the washer over the terminal gasket. Two holes, optionally tapped, are provided for connection of a voltage coil lead. One of the two holes remains free for connection even though the other may be covered by the current-coil conductor.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 242 words
A watthour meter, comprising: a base; at least one hole through said base; a surface surrouding said hole inside said base; a terminal; a generally planar terminal blade on said terminal projecting outward from said at least one hole; a generally planar offset portion on said terminal inside said base; said offset portion having first and second faces; said offset portion being generally parallel to said terminal blade; said offset portion being offset a predetermined distance from a center line of said terminal blade; a transverse portion connecting an inner extension of said terminal blade and said offset portion; a resilient terminal gasket surrounding said inner extension and bearing against said surface; a terminal washer surrounding said inner extension and bearing against an outer surface of said terminal gasket; said transverse portion having an under surface effective for bearing against said terminal washer at a first side of said terminal; a projection generally aligned on an opposed side of said terminal with said under surface; said projection forming a bearing surface for bearing against said terminal washer at a second side of said terminal; means for urging said terminal outward, whereby said transverse portion and said bearing surface apply compressive force on said terminal washer and said terminal gasket; and said predetermined distance being effective for permitting attachment to one of said first and second faces to conductors disposed in a vicinity of at least four transverse positions from said center line.
Claim 2
Dependent Claim 242 words
A watthour meter, comprising: a base; at least one hole through said base; a surface surrouding said hole inside said base; a terminal; a generally planar terminal blade on said terminal projecting outward from said at least one hole; a generally planar offset portion on said terminal inside said base; said offset portion having first and second faces; said offset portion being generally parallel to said terminal blade; said offset portion being offset a predetermined distance from a center line of said terminal blade; a transverse portion connecting an inner extension of said terminal blade and said offset portion; a resilient terminal gasket surrounding said inner extension and bearing against said surface; a terminal washer surrounding said inner extension and bearing against an outer surface of said terminal gasket; said transverse portion having an under surface effective for bearing against said terminal washer at a first side of said terminal; a projection generally aligned on an opposed side of said terminal with said under surface; said projection forming a bearing surface for bearing against said terminal washer at a second side of said terminal; means for urging said terminal outward, whereby said transverse portion and said bearing surface apply compressive force on said terminal washer and said terminal gasket; and said predetermined distance being effective for permitting attachment to one of said first and second faces to conductors disposed in a vicinity of at least four transverse positions from said center line.
Claim 3
Dependent Claim 36 words
A watthour meter according to claim 1 wherein said means for urging includes a pin hole through said terminal blade and a pin engaging said pin hole and bearing against an outer surface of said base.
Claim 4
Dependent Claim 14 words
A watthour meter according to claim 2 wherein said pin is a cotter pin.
