Abstract

An anti-kink protection assembly is proposed that is configured for being situated on a connector housing that is mounted on a cable for anti-kink protection, comprising a cylindrical base part that is formed in one piece from a top part and a bottom part. The bottom part includes multiple locking arms that are separated from one another by a distance in the radial direction, and locking tabs are in each case situated on the lower end areas of the locking arms facing away from the top part, in the direction of the inner area of the cylindrical base part. The bottom part has a defined internal cross section in the area of the locking arms without the locking tabs. Tt least one upper end element is situated at the upper outer edge of the top part facing away from the locking arms. In addition, the anti-kink protection assembly includes a ring that is configured for being pushed over the bottom part of the base part onto the top part in a preassembly step, and for abutting against the at least one upper end element, and in a final assembly step, being pushed in the opposite direction with respect to the preassembly step, from the top part in the direction of the bottom part, until reaching the lower end areas of the locking arms.

First claim

What is claimed is:

1. An anti-kink protection assembly ( 100 , 200 ) that is configured for being situated on a connector housing ( 400 ) that is connected to a cable ( 300 ) for anti-kink protection, comprising:
a cylindrical base part ( 100 ) that is formed in one piece from a top part ( 101 ) and a bottom part ( 102 ),
wherein the bottom part ( 102 ) includes multiple locking arms ( 10 ) that are separated from one another by a distance in the radial direction, and locking tabs ( 11 ) are in each case situated on the lower end areas ( 112 ) of the multiple locking arms ( 10 ) facing away from the top part ( 101 ), in the a direction of the an inner area of the cylindrical base part ( 100 ),
wherein the bottom part ( 102 ) has a defined internal cross section (D) in the area where the locking arms ( 10 ) are without the locking tabs ( 11 ),
wherein at least one upper end element ( 13 ) is situated at an upper outer edge of the top part ( 101 ) and spaced away from the locking arms ( 10 ), and
a ring ( 200 ) that is configured and designed for being pushed over the bottom part ( 102 ) of the base part ( 100 ) onto and toward an area of the top part ( 101 ) in a preassembly step (Si), and for abutting against the at least one upper end element ( 13 ), and in a final assembly step (S 2 ), thereafter being pushed in an opposite direction with respect to the preassembly step ( 51 ), from the top part ( 101 ) in the direction of the bottom part ( 102 ), until reaching the lower end areas of the locking arms ( 10 ).

2. The anti-kink protection assembly ( 100 , 200 ) according to claim 1 , wherein each of the locking arms ( 10 ), at an upper end facing the top part ( 101 ), have locking projections ( 12 ), each at a distance (A) from a lower end of the particular locking projection ( 12 ) facing away from the top part ( 101 ), to the lower end area ( 112 ) of the locking arm ( 10 ) facing away from the top part ( 101 ).

3. The anti-kink protection assembly ( 100 , 200 ) according to claim 2 , wherein the ring ( 200 ) has an upper end that abuts against the locking projections ( 12 ) after the final assembly step (S 2 ).

4. The anti-kink protection assembly ( 100 , 200 ) according to claim 2 , wherein the distance (A) corresponds to a width of the ring ( 200 ).

5. The anti-kink protection assembly ( 100 , 200 ) according to claim 3 , wherein the distance (A) corresponds to the width of the ring ( 200 ).

6. The anti-kink protection assembly ( 100 , 200 ) according to claim 4 , wherein a width of an area of the top part ( 101 ) between the lower end of the at least one end element ( 13 ) facing the bottom part ( 102 ) and the upper end of one of the locking projections ( 12 ) facing the top part ( 101 ) corresponds to the distance (A), and the ring ( 200 ) is pushed onto the area of the top part ( 101 ) in the preassembly step.

7. The anti-kink protection assembly ( 100 , 200 ) according to claim 5 , wherein a width of an area of the top part ( 101 ) between the lower end of the at least one end element ( 13 ) facing the bottom part ( 102 ) and the upper end of one of the locking projections ( 12 ) facing the top part ( 101 ) corresponds to the distance (A), and the ring ( 200 ) is pushed onto the area of the top part ( 101 ) in the preassembly step.

8. The anti-kink protection assembly ( 100 , 200 ) according claim 7 , wherein the bottom part ( 102 ) includes three, four, five, or six locking arms ( 10 ), and/or the top part ( 101 ) includes three, four, five, or six stop elements or locking elements configured as upper end elements ( 13 ) or as an at least partially circumferential edge.

9. The anti-kink protection assembly ( 100 , 200 ) according claim 6 , wherein the bottom part ( 102 ) includes three, four, five, or six locking arms ( 10 ), and/or the top part ( 101 ) includes three, four, five, or six stop elements or locking elements configured as upper end elements ( 13 ) or as an at least partially circumferential edge.

10. The anti-kink protection assembly ( 100 , 200 ) according to claim 9 , wherein the internal cross section in the area of the locking arms ( 10 ) is constant or becomes larger in the direction of the locking tabs ( 11 ) or of the upper end elements ( 13 ).

11. The anti-kink protection assembly ( 100 , 200 ) according to o claim 9 , wherein the locking arms ( 10 ) are made of a material, and formed from the top part ( 101 ) and situated thereon, in such a way that the locking arms ( 10 ) have a predetermined elasticity.

12. The anti-kink protection assembly ( 100 , 200 ) according to claim 1 , wherein the internal cross section in the area of the locking arms ( 10 ) is constant or becomes larger in the direction of the locking tabs ( 11 ) or of the upper end elements ( 13 ).

13. The anti-kink protection assembly ( 100 , 200 ) according to o claim 1 , wherein the locking arms ( 10 ) are made of a material, and formed from the top part ( 101 ) and situated thereon, in such a way that the locking arms ( 10 ) have a predetermined elasticity.
