Cable Lug Comprising a Nut or Functional Part, Method for the Production of Such a Cable Lug, and Nut

A cable lug in combination with a nut, comprising:

• said cable lug having a tubular receiving portion for a cable, an integrally formed flat part connecting portion connected to said tubular receiving portion, said flat part connecting portion having a hole therethrough defined by a wall, said hole having a central axis;
• and
• said nut comprising a body having an undercut, said nut being held captively and rotatable, on the flat part connecting portion, the nut not passing through the flat part connecting portion and being held by a reshaped holding material portion of the flat part connecting portion which projects into said undercut, said reshaped holding material portion being accommodated in the undercut, wherein an axial clearance is provided between said reshaped holding material and the wall which defines said hole.

A cable lug in combination with a functional part, comprising:

• said cable lug having a tubular receiving portion for a cable, an integrally formed flat part connecting portion connected to said tubular receiving portion, said flat part connecting portion having a hole therethrough defined by a wall, said hole having a central axis;
• and
• a functional part comprising a body having an undercut, said functional part being held captively and rotatable on the flat part connecting portion, the functional part being held by a holding material portion which projects into said undercut, this holding material portion being seated in a region sunk-in in a step-like mariner with respect to the unaffected surrounding region of the flat part connecting portion, the undercut being formed with an axial extent which is equal to or less than the axial extent of the unaffected flat part connecting portion, said step-like sunk-in region is rotationally symmetrical and has a conical portion which is open outward and upward and has at least one conical surface.

Method for forming a connection comprising:

• providing a cable lug and a functional part, the cable lug having a tubular receiving portion for a cable and a flat part connecting portion connected thereto, said flat part connecting portion having an aperture defined by a wall provided therethrough;
• pressing said nut into said flat part connecting portion by passing a portion of said nut through said hole such that a rotationally symmetrical circumferential step-like area comprising at least one step surface is formed in the flat part connecting portion, wherein at least one of the step surfaces forms a conical surface running at an acute angle to a horizontal or to a vertical.

Nut which can be inserted into a hole in a cable lug, comprising:

• a body having a radially opening undercut which is provided in an axial direction of the nut and has an upper delimiting surface and a lower delimiting surface, said undercut being formed to be rotationally symmetrical and the upper delimiting surface is part of a rotationally symmetrical stepped area.
