Abstract

A housing component for a plug connector, in particular an end cap for a plug connector housing, having a cable-side axial portion and a plug-side axial portion adjoining the cable-side portion along a longitudinal axis. A cable bushing for a cable is formed in the cable-side portion and runs along the longitudinal axis. It is provided that the housing component has at least one fluid channel running in the cable bushing and being open towards the cable, in order to conduct away a fluid which has penetrated between the cable bushing and the cable in a defined manner into the plug-side portion. The fluid channel winds through the cable bushing at least in portions along the longitudinal axis. At least one outlet opening is formed in the plug-side portion in order to discharge the fluid from the housing component transversely to the longitudinal axis.

First claim

What is claimed is:

1 . A housing component for a plug connector, in particular an end cap for a plug connector housing, comprising:
a cable-side axial portion and a plug-side axial portion adjoining the cable-side portion along a longitudinal axis, the cable-side portion having a cable bushing for a cable running along the longitudinal axis; at least one fluid channel formed in the cable bushing and open towards the cable, in order to conduct away a fluid which has penetrated between the cable bushing and the cable in a defined manner into the plug-side portion, the fluid channel winding through the cable bushing at least in portions along the longitudinal axis, and at least one outlet opening being formed in the plug-side portion in order to discharge the fluid from the housing component transversely to the longitudinal axis (L); wherein the plug-side portion has, at least in some regions, at least one outer wall running around the longitudinal axis in order to delimit, at least in some regions, a cavity, the at least one fluid channel opening out into the cavity; and wherein the at least one outlet opening is formed in the at least one outer wall and/or between a plurality of said outer walls.

2 . The housing component according to claim 1 , further comprising:
at least one elevation, in particular a rib, formed on an inner lateral surface of the cable bushing and winding through the cable bushing at least in portions along the longitudinal axis in order to form the at least one fluid channel.

3 . The housing component according to claim 1 , wherein the at least one fluid channel is formed in such a way that the cable can rest on the fluid channel in order to seal the fluid channel on the inside, in the direction of the longitudinal axis.

4 . The housing component according to claim 1 , wherein the at least one fluid channel winds through the cable bushing in such a way that a direct passage for the fluid through the cable-side portion into the plug-side portion, said passage running solely longitudinal axial direction, is blocked.

5 . The housing component according to claim 1 , wherein the at least one fluid channel winds helically through the cable bushing.

6 . A housing component for a plug connector, in particular an end cap for a plug connector housing, comprising:
a cable-side axial portion and a plug-side axial portion adjoining the cable-side portion along a longitudinal axis, the cable-side portion having a cable bushing for a cable running along the longitudinal axis; at least one fluid channel formed in the cable bushing and open towards the cable, in order to conduct away a fluid which has penetrated between the cable bushing and the cable in a defined manner into the plug-side portion, the fluid channel winding through the cable bushing at least in portions along the longitudinal axis, and at least one outlet opening being formed in the plug-side portion in order to discharge the fluid from the housing component transversely to the longitudinal axis (L); wherein the plug-side portion has, at least in some regions, at least one outer wall running around the longitudinal axis in order to delimit, at least in some regions, a cavity, the at least one fluid channel opening out into the cavity; and a plug-side volume provided to the fluid by means of the cavity being larger than a cable-side volume provided to the fluid in the cable-side portion.

7 . The housing component according to claim 1 , wherein the inner diameter of the housing component in the plug-side portion is larger than in the cable bushing, and a support surface running transversely to the longitudinal axis being formed between the cable bushing and the at least one outer wall.

8 . The housing component according to claim 7 , further comprising:
a plurality of support elements arranged distributed on the support surface, preferably uniformly distributed around the cable bushing, in order to mechanically contact a sealing element of the plug connector adjacent to the housing component; at least one intermediate channel being formed in each of the support elements and/or between the support elements; and the at least one fluid channel opening out into the at least one intermediate channel.

9 . The housing component according to claim 8 , wherein the at least one fluid channel has, at a plug-side end portion, a deflecting portion running at least substantially parallel to the longitudinal axis in order to introduce the fluid in a targeted manner, starting from the fluid channel, into one of the intermediate channels.

10 . The housing component according to claim 8 , wherein between the at least one outer wall and the support elements, there is formed running around the support elements an outer channel, into which the individual intermediate channels open out, and which is designed to conduct the fluid to the at least one outlet opening.

11 . A plug connector comprising the housing component according to claim 1 and at least one sealing element adjacent along the longitudinal axis to the plug-side portion of the housing component or arranged in the plug-side portion and mountable externally on the cable.

12 . A plug connector assembly comprising the plug connector according to claim 11 and the cable.

13 . A housing component for a plug connector, in particular an end cap for a plug connector housing, comprising:
a cable-side axial portion and a plug-side axial portion adjoining the cable-side portion along a longitudinal axis, the cable-side portion having a cable bushing for a cable running along the longitudinal axis; and a cable-side volume for a fluid penetrated between the cable bushing, wherein the cable-side volume in the cable-side portion is smaller than a plug-side volume provided to the fluid in the plug-side portion, with at least one outlet opening being formed in the plug-side portion in order to discharge the fluid from the housing component transversely to the longitudinal axis, wherein the plug-side portion has, at least in some regions, at least one outer wall running around the longitudinal axis in order to delimit, at least in some regions, a cavity, the at least one fluid channel opening out into the cavity.
