Abstract

A cable sealing plug includes a cable pass through opening extending through the cable sealing plug in an axial direction, a compression seal extending around the cable pass through opening, and a locking part having a locking system. The compression seal is transferable to a compressed state in which an inner diameter of the compression seal is smaller than a predetermined cable diameter of an electric cable extending through the cable pass through opening. The locking part and the compression seal are formed as a unitary component.

First claim

What is claimed is:

1 . A cable sealing plug, comprising:
a cable pass through opening extending through the cable sealing plug in an axial direction; a compression seal extending around the cable pass through opening, the compression seal is transferable to a compressed state in which an inner diameter of the compression seal is smaller than a predetermined cable diameter of an electric cable extending through the cable pass through opening; and a locking part having a locking system, the locking part and the compression seal are formed as a unitary component.

2 . The cable sealing plug of claim 1 , further comprising a compression ring arranged at an axial end of the cable sealing plug opposite the locking part.

3 . The cable sealing plug of claim 2 , wherein the compression seal is located between the locking part and the compression ring.

4 . The cable sealing plug of claim 1 , further comprising an axially projecting shoulder on a surface where the locking part and the compression seal are connected to each other.

5 . The cable sealing plug of claim 1 , wherein the compression seal has a radially projecting pressure bead on an outer side and/or an inner side of the compression seal.

6 . The cable sealing plug of claim 5 , wherein the radially projecting pressure bead is a radially inwardly projecting pressure bead abutting directly against the locking part in the axial direction.

7 . The cable sealing plug of claim 1 , further comprising a shell surface formed at least in sections by the locking part and the compression seal.

8 . The cable sealing plug of claim 7 , wherein the locking system is arranged on the shell surface of the locking part.

9 . The cable sealing plug of claim 1 , wherein the locking part has a handling area on an end face facing away from the compression seal.

10 . The cable sealing plug of claim 9 , wherein the handling area increases axially and/or radially along a circumferential direction.

11 . The cable sealing plug of claim 2 , wherein the compression ring is formed of an electrically conductive material.

12 . The cable sealing plug of claim 2 , wherein the unitary component includes the compression seal, the locking part, and the compression ring.

13 . The cable sealing plug of claim 2 , wherein the compression ring has an extension projecting away from the compression seal in the axial direction.

14 . An electric connector, comprising:
a housing having an inner wall, a cable opening, and a locking device; and a cable sealing plug disposed in the cable opening, the cable sealing plug including a cable pass through opening extending through the cable sealing plug in an axial direction, a compression seal extending around the cable pass through opening, and a locking part having a locking system, the locking part and the compression seal are formed as a unitary component, the locking system is complementary to the locking device and fixes the cable sealing plug in a blocking position in the housing, the compression seal is pressed against the inner wall of the housing in the blocking position.

15 . The electric connector of claim 14 , further comprising an electric cable having a predetermined cable diameter, the electric cable extending through the cable pass through opening.

16 . The electric connector of claim 15 , wherein the compression seal is transferable to a compressed state in which an inner diameter of the compression seal is smaller than the predetermined cable diameter.

17 . The electric connector of claim 14 , wherein the cable sealing plug is located completely in the housing in the blocking position.

18 . The electric connector of claim 14 , wherein the locking part and the compression seal are formed as a unitary component.

19 . The electric connector of claim 14 , wherein the cable sealing plug includes a compression ring arranged at an axial end of the cable sealing plug opposite the locking part.

20 . The electric connector of claim 19 , wherein the housing has an annular pocket, the compression ring or the compression seal projects at least in sections into the annular pocket in the blocking position.
