Plug-in connector with strain relief

1. Plug-in connector having a base element ( 10 ) containing at least one insulation displacement contact ( 13 , 14 ) which bonds and locates an at least single-core insulated cable ( 40 ) in the assembled condition of the plug-in connector ( 11 ), wherein the base element ( 10 ) comprises at least one inelastic clamping element ( 15 , 16 , 17 , 21 ) the length of which is selected so that in the assembled condition of the plug-in connector ( 11 ) the clamping element ( 15 , 16 , 17 , 21 ) deforms the cable insulation ( 43 ) of the cable ( 40 ) or penetrates the cable insulation ( 43 ) at least in part thereby clamping the cable ( 40 ), wherein at least one clamping element ( 17 ) is provided that clamps a connection web ( 44 ) of the cable ( 40 ), extending between two neighboring cores ( 41 ), in the mounted condition of the plug-in connector ( 11 ), wherein the clamping element ( 17 ) comprises a pointed tip ( 19 ) that clamps the connecting web ( 44 ) in the assembled condition of the plug-in connector ( 11 ), wherein the width of that clamping element ( 17 ) is selected to ensure that at least one core ( 41 ) of two neighboring cores ( 41 ) of the cable ( 40 ) is additionally clamped by the clamping element ( 17 ), wherein the plug-in connector ( 11 ) comprises an upper part ( 12 ) that presses the cable ( 40 ) onto the base element ( 10 ) in the mounted condition of the plug-in connector ( 11 ), and wherein the upper part ( 12 ) comprises at least one guide channel ( 33 ) into which the at least one clamping element ( 15 , 16 , 17 , 21 ) is inserted during assembly of the plug-in connector ( 11 ).

2. The plug-in connector as defined in claim 1 , wherein the clamping element ( 15 , 16 , 17 , 21 ) is arranged immediately adjacent an insulation displacement contact ( 13 , 14 ).

3. The plug-in connector as defined in claim 1 , wherein at least one clamping element ( 15 , 16 , 17 , 21 ) is provided before and behind the insulation displacement contact ( 13 , 14 ), related to the longitudinal direction ( 20 ) of the cable ( 40 ).

4. The plug-in connector as defined in claim 1 , wherein at least one clamping element ( 15 , 16 , 17 , 21 ) is made from an electrically non-conductive plastic material.

5. The plug-in connector as defined in claim 1 , wherein the clamping element ( 15 , 16 , 17 , 21 ) clamps the cable insulation ( 43 ) relative to the insulation displacement contact ( 13 , 14 ) at least approximately in the area of the diameter of the core ( 41 ), related to the mounting direction of the cable.

6. The plug-in connector as defined in claim 1 , wherein the pointed tip ( 18 , 19 , 22 , 23 ) is oriented in the longitudinal direction ( 20 ) of the cable ( 40 ).

7. The plug-in connector as defined in claim 1 , wherein the clamping element ( 1 , 5 16 , 17 , 21 ) comprises a plurality of pointed tips ( 22 , 23 ).

8. The plug-in connector as defined in claim 1 , wherein the upper part ( 12 ) contains at least one cable duct ( 31 ) intended to receive the cable ( 40 ).

9. The plug-in connector as defined in claim 1 , wherein the upper part ( 12 ) comprises an abutment ( 35 ) arranged approximately opposite the clamping element ( 15 , 16 , 17 , 21 ) in the assembled condition of the plug-in connector ( 11 ).

10. The plug-in connector as defined in claim 1 , wherein the upper part ( 12 ) comprises at least one positioning element ( 30 ) that positions the upper part ( 12 ) relative to the base element ( 10 ) during assembly of the plug-in connector ( 11 ).

11. The plug-in connector as defined in claim 1 , wherein the upper part ( 12 ) comprises at least two detents ( 34 ) that lock the upper part ( 12 ) on the base element ( 10 ) at the end of the assembly process.
