Abstract
The invention concerns a spring-force clamp connector for connecting an electrical conductor, which has a conductive core piece with a four-cornered material passage according to this design, in which the end of the clamping member of a leaf spring penetrates such that the end of the clamping member forms a clamping site for the electrical conductor together with an inner wall area of the aperture collar of the material passage. It is proposed to use for the inner wall area of the aperture collar of the material passage a new shaping with a cross edge/edge and to arrange the clamping site for the electrical conductor deep in the material passage, whereby at the same time a metal-encased conductor pre-capture pocket is formed.
Claims6
A spring-force clamp connector for connecting an electrical conductor comprising:
- a substantially planar conductive core piece having an opening comprising a four-cornered material passage constructed and arranged to receive the electrical conductor therethrough, the material passage including an aperture collar extending in the direction of the passage, the aperture collar including an inner wall;
- a leaf spring including a clamping member, the clamping member having a first end that is inserted into the passage such that it forms with the inner wall of the aperture collar a clamping site for the electrical conductor;
- a cross edge disposed adjacent the inner wall area of the aperture collar, the cross edge projecting against the electrical conductor and extending crosswise to the direction of the passage;
- and
- wherein the clamping member spring is constructed and arranged such that an end-side clamping edge of the clamping member lies substantially opposite the cross edge when the electrical conductor is clamped.
A spring-force clamp connector with a substantially planar conductive core piece for connecting an electrical conductor comprising:
- an opening constructed and arranged to receive the conductor therethrough, the opening having a shape of a four-cornered material passage, and further including an aperture collar extending in the direction of the passage, the aperture collar including an annular, closed wall;
- a leaf spring including a clamping member, the clamping member having a first end that is inserted into the passage such that it forms with the inner wall of the aperture collar a clamping site for the electrical conductor, the clamping site having an uncoated surface;
- an end-side partial piece disposed at the uncoated and closed clamping site, the partial piece being disposed within the contour of the passage, the partial piece having a surface area which is the same size as or larger than the nominal cross section of the conductor to be clamped;
- and
- wherein the annular, closed inner wall area of the aperture collar with the end-side partial piece of the clamping member forms a conductor pre-capture pocket that is encased in metal for a forward end of the electrical conductor to be inserted.
A spring-force clamp connector with a substantially planar conductive core piece for connecting an electrical conductor comprising:
- an opening constructed and arranged to receive the conductor therethrough, the opening having a shape of a four-cornered material passage, and further including an aperture collar extending in the direction of the passage, the aperture collar including an inner wall;
- a leaf spring including a clamping member, the clamping member having a first end that is inserted into the passage such that it forms with the inner wall of the aperture collar a clamping site for the electrical conductor,
- a central partial piece of the clamping member of the leaf spring disposed outside of the contour of the passage, the central partial piece including a front convexity in the direction of the spring clamping force of the clamping member of the leaf spring;
- and wherein
- upon a pressing tool being placed on the front convexity and substantially perpendicular to the upper side of the conductive core piece, the clamping member is pushed back to an up position in which the clamping site is completely opened.
