Abstract

The invention relates to a method for producing a nut which is rotationally connected to a flat part connecting section of a cable shoe, wherein the flat part connecting section has a passage opening, the nut has a sitting face which is at the bottom in the connected state, and a holder section extends on the nut from the sitting face further downward, wherein a tapered portion of the passage opening is formed by a holder material section which is preliminarily curved into the passage opening by deformation, and the holder material section is produced by a recess which is made in the flat part connecting section so as to surround the passage opening on a top side of the flat part connection section, which top side is associated with the sitting face. In order to specify a method of this kind which can be carried out in respect of production, in particular in respect of the production costs, in a favourable manner, it is proposed that the holder material section is first formed and the nut is placed onto the top side, wherein the holder section protrudes downward beyond a narrowest cross section of the passage opening which is formed by the holder material section, and that the holder section is then widened below the narrowest cross section, for the purpose of holding the nut on the cable shoe in a rotatable and interlocking manner. The invention further relates to a nut which is fitted in a rotatable manner on a flat part connecting section of a cable shoe.

First claim

The invention claimed is:

1. A method for connecting a nut to a flat part connecting section of a cable shoe comprising:
providing the nut having a seating face at a bottom thereof, and a holder section extending downward from the seating face;
providing the flat part connecting section;
forming a passage opening in the flat part connecting section;
forming a recess around the passage opening in a top side of the flat part connecting section, thereby deforming a holder material section of the flat part connecting section to form a tapered portion of the passage opening which curves into the passage opening, the holder material section forming a narrowest cross section of the passage opening;
inserting the nut into the passage opening through the top side of the flat part connecting section with the holder section of the nut protruding downward beyond the holder material section; and
widening the holder section of the nut underneath the holder material section, thereby holding the nut on the flat part connecting section in a freely rotatable and interlocking manner.

2. The method according to claim 1 , further comprising surface treating the flat part connecting section before attaching the nut to the flat part connecting section.

3. The method according to claim 1 , wherein the forming of the passage opening in the flat part connecting section and the forming of the recess are done at the same time.

4. The method according to claim 1 , wherein the forming of the passage opening in the flat part connecting section is done prior to the forming of the recess.

5. The method according to claim 1 , wherein the holder section of the nut is widened by plastic deformation.

6. A combination comprising:
a nut comprising a seating face at a bottom thereof, the seating face extending linearly from an opening through the nut, and a holder section extending downward from the seating face; and
a flat part connecting section of a cable shoe, the flat part connecting section comprising a bottom side and a linearly extending top side, a passage opening extending between the top side and the bottom side, a recess extending downward from the top side, the recess surrounding the passage opening and being spaced outwardly from the passage opening, and a holder material section forming a tapered portion of the passage opening which is curves into the passage opening and forms a narrowest cross section of the passage opening,
wherein the seating face of the nut is seated on the top side of the flat part connecting section and covers the recess but does not enter into the recess, and the holder section protrudes downward beyond the holder material section and extends underneath the holder section, such that the nut is held on the flat part connecting section in a freely rotatable and interlocking manner.

7. The nut according to claim 6 , wherein the recess a circumferential groove.
