Cable transit and method for manufacturing such cable transit
A cable transit ( 100 ) is formed in one piece and comprises a frame ( 102 ) and a body formed from resilient material. The frame ( 102 ) is dimensioned to be inserted into an opening of a separating wall and has an axial extension L from a first end ( 104 ) to a second end ( 106 ). At least one through-hole ( 108 ) extends through the body in the axial extension thereof, and the cable transit is characterized in that the at least one through-hole ( 108 ) is defined by a cylindrical rim portion ( 110 ) and in that a volume ( 114 ) between the cylindrical rim portion ( 110 ) of the at least one through-hole and a frame ( 102 ) of the cable transit is recessed.
1. A cable transit formed in one piece, comprising
a frame and a body formed from resilient material, the frame being dimensioned to be inserted into an opening of a separating wall and having an axial extension L from a first end to a second end,
at least one through-hole extending through the body in the axial extension thereof,
wherein at least one through-hole is defined by a cylindrical rim portion and a recess is defined by the cylindrical rim portion and the frame, the recess being partitioned by a diaphragm.
2. The cable transit of claim 1 , wherein the recess extends from the first end of the body.
3. The cable transit of claim 1 , wherein the recess extends from both the first end and the second end of the body, and wherein the recess extending from the first end of the body is arranged opposite to the recess extending from the second end of the body.
4. The cable transit of claim 3 , wherein the diaphragm is arranged at an approximate middle of the body, in the axial extension thereof.
5. The cable transit of claim 1 , wherein a solid material bridge extends between the frame and the at least one through-hole.
6. The cable transit of claim 1 , further comprising a slit extending from a radial perimeter of the body, into the at least one through-hole and along the axial extension of the body.
7. The cable transit of claim 1 , further comprising at least two through-holes, wherein a support structure of solid material extends between the cylindrical rim portions of said at least two through-holes.
8. The cable transit of claim 1 , wherein the frame of the body is formed from solid material, providing structural stability to the cable transit.
9. The cable transit of claim 1 , wherein the at least one through-hole is partitioned by a membrane at a position between the first end and the second end of the body.
10. The cable transit of claim 1 , wherein the frame tapers off in the direction of the second end.
11. The cable transit of claim 1 , further comprising a radial flange extending outwardly from the first end of the body.
12. The cable transit of claim 1 , wherein at least the body is formed from a silicone compound or rubber compound, wherein material of the body has a hardness of 30-70 Shore A.
13. The cable transit of claim 12 , wherein the frame is formed from the same material as the body.
14. The cable transit of claim 1 , the cable transit having a cross-sectional shape being circular, oval or polygonal, such as quadratic, rectangular, pentagonal, hexagonal, heptagonal or octagonal.
