Abstract

A cable lug or functional part in combination with a nut is provided. The cable lug or functional part has a tubular receiving portion for a cable, an integrally formed flat part connecting portion connected to the tubular receiving portion, the flat part connecting portion having a hole therethrough defined by a wall said hole having a central axis. The nut includes a body having an undercut. The nut is held captively and rotatably on the flat part connecting portion. The nut does not pass through the flat part connecting portion is held by a reshaped holding material portion of the flat part connecting portion which projects into the undercut. The reshaped holding material portion is accommodated in the undercut, and an axial clearance is provided between the reshaped holding material and the wall which defines the hole.

First claim

1 . 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 formed on said nut, 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.

2 . The combination according to claim 1 , wherein the holding material portion is accommodated in the undercut with radial play.

3 . The combination according to claim 1 , wherein the holding material portion has a surface which faces the nut or the functional part and runs directly into a conical area of the flat part connecting portion.

4 . The combination according to claim 1 , wherein the holding material portion is formed to be rotationally symmetrical.

5 . The combination according to claim 3 , wherein the conical area of the conical portion is formed to be rotationally symmetrical.

6 . The combination according to claim 3 , wherein two conical surfaces are provided, and in that at least one of the conical surfaces of the conical portion runs at an acute angle to a horizontal or a vertical.

7 . The combination according to claim 1 , wherein the undercut is formed outside a thread of the nut or the functional part.

8 . The combination according to claim 1 , wherein an inner face of the portion which forms the undercut has a cylindrical surface.

9 . The combination according to claim 8 , wherein the cylindrical surface of the undercut merges into the thread root of the nut.

10 . The combination according to claim 1 , wherein both an upper and a lower delimiting surface of the undercut overlap the flat part connecting portion in a lateral projection.

11 . The combination according to claim 10 , wherein the lower delimiting surface of the undercut extends over more than half of the associated stepped area in a vertical projection.

12 . The combination according to claim 10 , wherein an upper delimiting surface of the undercut is part of a stepped area.

13 . The combination according to claim 1 , wherein the hole is formed with a hole step.

14 . The combination according to claim 13 , wherein the hole step is formed in the lower region of the hole which faces away from the nut or functional parts.

15 . The combination according to claim 13 , wherein the hole step projects toward the interior of the hole.

16 . The combination according to claim 13 , characterized in that wherein a radial extent of the hole step corresponds to a radial depth of the undercut.

17 . The combination according to claim 13 , wherein, in terms of depth, the hole step is formed outside the lower region of the nut or functional part.

18 . 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 manner 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.

19 . The combination according to claim 18 , wherein the holding material portion is accommodated in the undercut with radial play.

20 . The combination according to claim 18 , wherein the conical area runs directly into a surface of the holding material portion, which surface faces the functional part.

21 . The combination according to claim 18 , wherein the holding material portion is formed to be rotationally symmetrical.

22 . The combination according to claim 18 , wherein the conical area of the conical portion is formed to be rotationally symmetrical.

23 . The combination according to claim 18 , wherein two conical surfaces are provided, and in that at least one of the conical surfaces of the conical portion runs at an acute angle to a horizontal or a vertical.

24 . The combination according to claim 18 , wherein the undercut is formed outside a thread of the nut or the functional part.

25 . The combination according to claim 18 , wherein both an upper and a lower delimiting surface of the undercut overlap the flat part connecting portion in a lateral projection.

26 . The combination according to claim 10 , wherein the lower delimiting surface of the undercut extends over more than half of the associated stepped area in a vertical projection.

27 . The combination according to claim 10 , wherein an upper delimiting surface of the undercut is part of a stepped area.

28 . The combination according to claim 18 , wherein the hole is formed with a hole step.

29 . The combination according to claim 28 , wherein the hole step is formed in the lower region of the hole which faces away from the nut or functional part.

30 . The combination according to claim 28 , wherein the hole step projects toward the interior of the hole.

31 . combination according to claim 28 , characterized in that wherein a radial extent of the hole step corresponds to a radial depth of the undercut.

32 . The combination according to claim 28 , wherein, in terms of depth, the hole step is formed outside the lower region of the nut or functional part.

33 . 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.
