Abstract
A joint for electrical conductors includes a connecting member having a longitudinal groove therein for receiving joining portions on a pair of electrical conductors. Biasing means carried by the conductors act against the groove bottom for biasing joining surfaces on the conductors into firm engagement with joining groove surfaces. The joint accommodates longitudinal thermal expansion and contraction of busbars or the like.
Claims13
A joint comprising a pair of elongated electrical conductors having end portions which are connected, said end portions having longitudinal axes, main body portions and joining portions, said joining portions having joining portion surfaces facing generally toward said main body portions in spaced relationship thereto, a connecting member having a longitudinal groove therein, said groove having a longitudinal groove opening along the length of said connecting member and opposite end groove openings at the opposite ends of said connecting member, said groove having a groove bottom spaced inwardly of said connecting member from said longitudinal groove opening, said groove having joining groove surfaces facing generally toward said groove bottom, said end portions of said conductors having said joining portions extending into said groove through said end groove openings with said longitudinal axes aligned, said main body portions of said end portions being located outside said groove adjacent said longitudinal groove opening, and independent yieldable biasing means mounted on and carried by each said joining portion on each said end portion independently of said connecting member for biasing against said groove bottom and urging said joining portion surfaces into engagement with said joining groove surfaces.
An elongated electrical conductor having a longitudinal axis and an end portion including a terminal end, said conductor including a main body portion having a generally flat outer surface and an integral joining portion extending from said main body portion opposite from said flat outer surface, said joining portion having joining surfaces facing generally toward said main body portion in outwardly-spaced relationship thereto, joining means attached to said joining portion at said end portion for joining said end portion to a connector, said joining means comprising a one-piece joining member including an attaching portion receiving said joining portion and an integral bowed spring portion extending upwardly and then downwardly in a direction from said attaching portion toward said terminal end, and said attaching portion and said joining portion being fixed against longitudinal movement relative to one another.
An elongated electrical conductor having a longitudinal axis and an end portion including a terminal end, said conductor including a main body portion having a generally flat outer surface and an integral joining portion extending from said main body portion opposite from said flat outer surface, said joining portion having joining surfaces facing generally toward said main body portion in outwardly-spaced relationship thereto and having a transverse slot therein, joining means attached to said joining portion at said end portion for joining said end portion to a connector, said joining means including an attaching portion receiving said joining portion, said attaching portion including a rearwardly extending tang having a downwardly bent portion received in said slot, and said joining means including a bowed spring portion extending upwardly and then downwardly in a direction from said attaching portion toward said terminal end.
