Abstract
Abstract An arrangement for sealing a cable bushing for at least one connecting cable, and in particular for a connecting cable of a sensor element of a gas sensor. On the terminal side, the sensor element is arranged in a metallic housing which has a tubular opening, in which a sealing arrangement is disposed, through which the connecting cable is conducted. The sealing arrangement is fixedly surrounded by the housing and has an elastically deformable sealing element and a spring element acting in the direction of the leading-through of the connecting cable, the sealing element being elastically deformed by the spring energy of the spring element.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
96 words
An arrangement for sealing a cable bushing for at least one connecting cable, the at least one connecting cable including a first end extending though an opening in a housing, the arrangement comprising: a sealing arrangement situated in the opening in the housing, the sealing arrangement including: an elastically deformable sealing element, and a spring element, a spring force of the spring element acting in an axial direction with respect to the first end of the at least one connecting cable, wherein the sealing element is elastically deformed by the spring force of the spring element.
Claim 2
Dependent Claim
96 words
An arrangement for sealing a cable bushing for at least one connecting cable, the at least one connecting cable including a first end extending though an opening in a housing, the arrangement comprising: a sealing arrangement situated in the opening in the housing, the sealing arrangement including: an elastically deformable sealing element, and a spring element, a spring force of the spring element acting in an axial direction with respect to the first end of the at least one connecting cable, wherein the sealing element is elastically deformed by the spring force of the spring element.
Claim 3
Dependent Claim
68 words
The arrangement according to claim 1, further comprising: two members situated in the opening in the housing and being at least axially maintained in a predetermined position, one of the two members positioned behind another one of the two members in the direction of the first end of the at least one connecting cable, wherein the sealing element and the spring element are positioned between the two members.
Claim 4
Dependent Claim
60 words
The arrangement according to claim 2, wherein one of the two members is a supporting structure for the spring element, and another one of the two members is a counterpart element for the sealing element, and wherein the sealing element is elastically deformed when the sealing element is pressed against the counterpart element by the force of the spring element.
Claim 5
Dependent Claim
81 words
The arrangement according to claim 3, wherein the supporting structure includes a ceramic machined part having at least one graduated lead-through portion receiving the at least one connecting cable, and wherein the at least one connecting cable is coupled to a crimp connection, the crimp connection including a widening portion which widens toward the at least one connecting cable, the widening portion gripping the at least one graduated lead-through portion from a rear end of the at least one connecting cable.
Claim 6
Dependent Claim
78 words
The arrangement according to claim 1, wherein the sealing element includes a disk-shaped member having a first lead-through portion, the first lead-through portion receiving the at least one connecting cable, the disk-shaped member substantially filling a cross-section of the opening in the housing, and wherein the sealing arrangement further includes a sleeve member premolded on the disk-shaped member at the first lead-through portion, the sleeve member surrounding the at least one connecting cable at the first lead-through portion.
Claim 7
Dependent Claim
25 words
The arrangement according to claim 5, further comprising: a counterpart including second lead-through portions, wherein the sleeve member is inserted through the second lead-through portions.
Claim 8
Dependent Claim
24 words
The arrangement according to claim 1, wherein the at least one connecting cable is a cable of a sensor element of a gas sensor.
