Abstract

A grommet for feeding a stranded element through an opening includes a first grommet element having an elongated first body with a first collar radially extended relative to the first body. The grommet includes a second grommet element having an elongated second body with a second collar radially extended relative to the second body. The first grommet element and the second grommet element are formed separately from each other. A feedthrough includes the grommet, and a method includes feeding a stranded element through an opening.

Claims (80)

1 . A grommet for feeding a stranded element through an opening, the grommet comprising:

a first grommet element comprising an elongated first body with a first collar radially extended relative to the first body; and

a second grommet element comprising an elongated second body with a second collar radially extended relative to the second body;

wherein the first grommet element and the second grommet element are formed separately from each other; and

wherein:

the first collar circumferentially projects beyond a circumferential end of the first body to circumferentially overlap with the second body; and/or

the second collar circumferentially projects beyond a circumferential end of the second body to circumferentially overlap with the first body.

2 . The grommet of claim 1 , wherein the first body and the second body are each configured to be brought together at respective contact surfaces to complement each other circumferentially and/or radially to form the grommet.

3 . The grommet of claim 1 , wherein the first body comprises a first cavity and the second body comprises a second cavity, the first and second cavities complementing each other when the first body and the second body are brought together in a direction transverse to an elongation direction, for receiving the stranded element.

4 . The grommet of claim 1 , wherein the first body and the second body are arrangeable to contact each other transverse to their an elongation direction, with the first collar and the second collar facing away from each other.

5 . The grommet of claim 1 , wherein the first body and the second body are arrangeable offset relative to each other along an elongation direction.

6 . The grommet of claim 1 , wherein:

when the first collar circumferentially projects beyond the circumferential end of the first body to circumferentially overlap with the second body, the second body is guided inside a corresponding projecting section of the first collar along the first body; and/or

when the second collar circumferentially projects beyond the circumferential end of the second body to circumferentially overlap with the first body, the first body is guided inside a corresponding projecting section of the second collar along the second body.

7 . The grommet of claim 6 , wherein:

the corresponding projecting section of the first collar and the corresponding projecting section of the second collar intersect along the first body and the second body.

8 . The grommet of claim 1 , wherein:

the first body comprises a first groove formed on an opposite end of the first body from the first collar; and/or

the second body comprises a second groove formed on an opposite end of the second body from the second collar; and

wherein the first collar and the second collar are each configured for attaching a tie.

9 . The grommet of claim 8 , wherein:

when the tie is arranged within the first groove, the tie is configured to intersect the second collar; and/or

when the tie is arranged within the second groove, the tie is configured to intersect the first collar.

10 . The grommet of claim 1 , wherein:

the first grommet element and the second grommet element are insertable into the opening from opposite directions, or from opposite axial directions;

the first grommet element and the second grommet element are formed identically to each other; and/or

the grommet is an additive manufacturing part.

11 . A feedthrough arrangement, comprising:

an opening; and

the grommet according to claim 1 ;

wherein the first grommet element and the second grommet element are inserted into the opening from opposite directions.

12 . A method for feeding a stranded element through an opening, the method comprising:

feeding the stranded element through the opening;

providing the grommet according to claim 1 ;

inserting the first grommet element into the opening and around the stranded element from a first side; and

inserting the second grommet element into the opening and around the stranded element from a second side, which is opposite the first side.

13 . A grommet for feeding a stranded element through an opening, the grommet comprising:

a first grommet element comprising an elongated first body with a first collar radially extended relative to the first body; and

a second grommet element comprising an elongated second body with a second collar radially extended relative to the second body;

wherein the first grommet element and the second grommet element are formed separately from each other;

wherein:

the first body comprises a first groove formed on an opposite end of the first body from the first collar, the first groove being configured for attaching a tie that is arrangeable within the first groove of the first body to intersect the second collar of the second grommet element; and/or

the second body comprises a groove formed on an opposite end of the second body from the second collar, the second groove being configured for attaching a tie that is arrangeable within the second groove of the second body to intersect the first collar of the first grommet element.

14 . The grommet of claim 13 , wherein:

the first body and the second body are each configured to be brought together at respective contact surfaces to complement each other circumferentially and/or radially to form the grommet;

the first body comprises a first cavity and the second body comprises a second cavity, the first and second cavities complementing each other when the first body and the second body are brought together in a direction transverse to an elongation direction, for receiving the stranded element;

the first body and the second body are arrangeable to contact each other transverse to the elongation direction, with the first collar and the second collar facing away from each other;

the first body and the second body are arrangeable offset relative to each other along the elongation direction;

the first grommet element and the second grommet element are formed identically to each other; and/or

the grommet is an additive manufacturing part.

15 . A feedthrough arrangement, comprising:

an opening; and

the grommet according to claim 13 ;

wherein the first grommet element and the second grommet element are inserted into the opening from opposite directions.

16 . A method for feeding a stranded element through an opening, the method comprising:

feeding the stranded element through the opening;

providing the grommet according to claim 13 ;

inserting the first grommet element into the opening and around the stranded element from a first side; and

inserting the second grommet element into the opening and around the stranded element from a second side, which is opposite the first side.

17 . A grommet for feeding a stranded element through an opening, the grommet comprising:

a first grommet element comprising an elongated first body with a first collar radially extended relative to the first body; and

a second grommet element comprising an elongated second body with a second collar radially extended relative to the second body;

wherein the first grommet element and the second grommet element are formed separately from each other; and

wherein the first grommet element and the second grommet element are only configured for insertion into the opening from opposite axial directions.

18 . The grommet of claim 17 , wherein:

the first body and the second body are each configured to be brought together at respective contact surfaces to complement each other circumferentially and/or radially to form the grommet;

the first body comprises a first cavity and the second body comprises a second cavity, the first and second cavities complementing each other when the first body and the second body are brought together in a direction transverse to an elongation direction of the first body and the second body, for receiving the stranded element;

the first body and the second body are arrangeable to contact each other transverse to the elongation direction, with the first collar and the second collar facing away from each other;
