Connecting plug for a current supply rail arrangement intended particularly for lighting purposes and small-sized electrical motors

Claim 2

A connecting plug for a current supply rail arrangement provided with current conductors and a protective grounding lead, particularly for lighting purposes and small electric motors, said plug comprising; a casinglike body, contact fingers being separately flexibly fastened in the body; an eccentric for each said contact finger rotatably journaled in the body, each said eccentric upon being rotated displacing a corresponding contact finger between a position retracted within a casing and a position protruding therefrom for contact with the current conductors in the current supply rail; and a locking device adapted to be displaced by the action of the supply rail away from a position locking the rotation of the eccentrics as the plug is pushed to the bottom of the supply rail, said locking device comprising a locking cam formed on a turning spindle connecting said eccentrics, a locking clasp attached to said body and engaged with the locking cam; and a slide positioned in said body, said slide having one of end forming an operative element having a guiding means, said slide being displaceable between a locking position in which said operative element protrudes from said casing, and a releasing position in which said operative element is pushed into the casing and said guiding means displaces the locking clasp from its engagement with the locking cam.

Claim 3

A connecting plug as claimed in claim 1, wherein said operative element of the slide is adapted to protrude from the center portion of said casing, said portion being adapted to be positioned against the edge of an opening in the current supply rail.

Claim 4

A connecting plug for a current supply rail arrangement provided with current conductors and a protective grounding lead, particularly for lighting purposes and small electric motors, said plug comprising; a casinglike body; contact fingers being separately flexibly fastened in the body; an eccentric for each said contact finger rotatably journaled in the body, each said eccentric upon being rotated displacing a corresponding contact finger between a position retracted within a casing and a position protruding therefrom for contact with the current conductors in the current supply rail; and a locking device adapted to be displaced by the action of the supply rail away from a position locking the rotation of the eccentrics as the plug is pushed to the bottom of the supply rail, said locking device comprising a locking means formed on a turning spindle connecting the eccentrics, and a pivoting lever journaled in said body, said lever having one arm forming an operative element and another arm forming a locking element, said lever being pivotable between a locking position in which said operative element protrudes from said casing so as to engage the locking element with the locking element with the locking means on said spindle and a releasing position in which the operative element is pushed into the casing and the locking element is disengaged from said locking means.

Claim 5

A connecting plug for a current supply rail arrangement provided with current conductors and a protective grounding lead, particularly for lighting purposes and small electric motors, said plug comprising; a casinglike body; contact fingers being separately flexibly fastened in the body; an eccentric for each said contact finger rotatably journaled in the body, each said eccentric upon being rotated displacing a corresponding contact finger between a position retracted within a casing and a position protruding therefrom for contact with the current conductors in the current supply rail; and a locking device adapted to be displaced by the action of the supply rail away from a position locking the rotation of the eccentrics as the plug is pushed to the bottom of the supply rail, said locking device comprising a locking means formed on a turning spindle connecting the eccentrics, and a pivoting lever journaled in said body, said lever having one arm forming an operative element and another arm forming a locking element, said lever being pivotable between a locking position in which said operative element protrudes from said casing so as to engage the locking element with the locking element with the locking means on said spindle and a releasing position in which the operative element is pushed into the casing and the locking element is disengaged from said locking means.

Claim 6

A connecting plug according to claim 3, wherein said operative element of the lever is adapted to protrude from the center portion of said casing, said portion being adapted to be positioned against the bottom of said current supply rail.
