Total Claims: 15
Claim 1
Independent Claim
302 words
An electric power distribution system comprising at least one current-carrying track which has a hollow sectional portion provided with a continuous elongated slot at the front side of the track and in the interior of which extend at least two electrical conductors insulated from one another, said conductors being adapted to be brought into contact with corresponding contact parts of current collectors which may be detachably fitted at any point along said current-carrying track, at least one connecting device comprising a housing consisting of electrically insulated material and which can be inserted from one end of said current-carrying track into said hollow sectional portion thereof, said housing containing contact elements adapted to be brought into contact with said electrical conductors of said current-carrying track through corresponding orifices in said housing, said contact elements each being provided with connector means disposed within said housing for an input or output conductor wire, said connecting device having at least one locking screw which can be turned when Said housing is pushed into said hollow sectional portion of said track thereby to prevent unintentional sliding of said housing in said hollow sectional portion, at least one of said contact elements in said housing being adapted to extend through its associated orifice, a spring tending to urge said contact element into the interior of the housing and out of contact with its associated electrical conductors, and said locking screw being operatively connected to but insulated from said movable contact element in such manner that the latter, due to said locking screw being turned when securing the housing in the hollow sectional portion of the track, is automatically caused to move out of its associated orifice in said housing thereby overcoming the action of the spring to establish contact with its associated electrical conductor of said current-carrying track.
Claim 2
Dependent Claim
302 words
An electric power distribution system comprising at least one current-carrying track which has a hollow sectional portion provided with a continuous elongated slot at the front side of the track and in the interior of which extend at least two electrical conductors insulated from one another, said conductors being adapted to be brought into contact with corresponding contact parts of current collectors which may be detachably fitted at any point along said current-carrying track, at least one connecting device comprising a housing consisting of electrically insulated material and which can be inserted from one end of said current-carrying track into said hollow sectional portion thereof, said housing containing contact elements adapted to be brought into contact with said electrical conductors of said current-carrying track through corresponding orifices in said housing, said contact elements each being provided with connector means disposed within said housing for an input or output conductor wire, said connecting device having at least one locking screw which can be turned when Said housing is pushed into said hollow sectional portion of said track thereby to prevent unintentional sliding of said housing in said hollow sectional portion, at least one of said contact elements in said housing being adapted to extend through its associated orifice, a spring tending to urge said contact element into the interior of the housing and out of contact with its associated electrical conductors, and said locking screw being operatively connected to but insulated from said movable contact element in such manner that the latter, due to said locking screw being turned when securing the housing in the hollow sectional portion of the track, is automatically caused to move out of its associated orifice in said housing thereby overcoming the action of the spring to establish contact with its associated electrical conductor of said current-carrying track.
Claim 3
Dependent Claim
134 words
An electric power distribution system according to claim 1, in which a first clamping member is provided in the form of a plate capable of being positioned transversely over the elongated slot in the hollow sectional portion of said track, said first clamping member having at least one guide rib for engagement in the elongated slot in the hollow sectional portion, said locking screw passing through an orifice in said clamping member and through the elongated slot in the hollow sectional portion when said housing is inserted into the hollow sectional portion, thereby allowing said first clamping member to be moved towards said housing by turning said locking screw in order to clamp a part of the hollow section portion into which the housing is inserted between said housing and said first clamping member.
Claim 4
Dependent Claim
102 words
An electric power distribution system according to claim 1, in which an insulating member is provided in the form of a web and carries at its end portions at least two of said contact elements which are movable together with said insulating member and are adapted to be brought into contact respectively with said electrical conductors of said current-carrying track extending on both sides of the elongated slot in the hollow sectional portion, and in which said locking screw engages the middle portion of said insulating member, and said spring being supported on said insulating member, and a wall of said housing.
Claim 5
Dependent Claim
59 words
An electric power distribution system according to claim 3, in which a guide sleeve is provided having a screw-threaded bore and is secured perpendicularly at said middle of said web-shaped insulating member, said guide sleeve being slidable in an orifice in said housing and being surrounded by said spring which is in the form of a helical compression spring.
Claim 6
Dependent Claim
59 words
An electrical power distribution system according to claim 3, in which said contact elements are in the form of bladelike metal tabs which are secured to said insulating member and each having at its end portions screw-threaded bores for selectively receiving a clamping screw for forming a portion of said connector means for an input or output conductor wire.
Claim 7
Dependent Claim
75 words
An electric power distribution system according to claim 1, in which one of said contact elements is provided for a protective ground connection secured to the middle portion of a leaf spring, said leaf spring being secured by its end portions in said housing and having at each said end portions a screw-threaded bore for selectively receiving a clamping screw for forming another portion of said connector means for an input or output conductor wire.
