Abstract
A resilient electrical terminal includes a loop-shaped conductive resilient compression spring having a body portion, a clamping leg portion extending generally normal to said body portion, and a contact leg portion extending generally normal to said clamping leg portion, said clamping leg portion containing a window opening, and an electrically conductive bus bar arranged parallel with and adjacent said contact leg portion on the side thereof remote from said spring body portion, said bus bar extending at one end through said window opening, the free extremity of said spring clamping leg portion being bent adjacent the window through an acute angle relative to the axis of the clamping leg portion to cause the wall portion of the window opening remote from the spring body portion, thereby to define a first sharp edge, whereby when a conductor is inserted in the window opening between the bus bar and the window wall portion, the sharp edge digs into the adjacent peripheral portion of the conductor to inhibit removal thereof through said window. A similar second sharp edge is provided on a punched-out tongue portion of the bus bar for also digging into the periphery of the conductor …
