Abstract

A connector assembly for installation on a wall includes a main connector body introduced into a cut-out hole of the wall and a protective shell positioned on an inner side of the wall. The protective shell protects the main connector body from an insulation foam entering the main connector body when foamed in place. The protective shell has a front portion, a receptacle formed at the front portion and receiving a second end of the main connector body, a flange extending from and surrounding the receptacle, and a lead-through channel formed at a back portion of the protective shell. The flange is attached on the inner side of the wall and covers the cut-out hole. The lead-through channel has an internal flap routing a cable through the back portion in a meandering manner. The internal flap is inclined with respect to the lead-through channel.

First claim

What is claimed is:

1. A connector assembly for installation on a wall, comprising:
a main connector body introduced into a cut-out hole of the wall along a first direction; and
a protective shell positioned on an inner side of the wall, the protective shell protecting the main connector body from an insulation foam entering the main connector body when the protective shell and the main connector body are foamed in place, the protective shell including a front portion, a receptacle formed at the front portion and receiving a second end of the main connector body, a flange extending from and surrounding the receptacle, and a lead-through channel formed at a back portion of the protective shell, the flange is attached on the inner side of the wall and covers the cut-out hole, the lead-through channel has an internal flap routing a cable through the back portion in a meandering manner, the internal flap is inclined with respect to the lead-through channel.

2. The connector assembly of claim 1 , wherein the protective shell has a pair of halves that are substantially symmetrical around a second direction perpendicular to the first direction.

3. The connector assembly of claim 2 , wherein the halves are connected by a film hinge.

4. The connector assembly of claim 2 , wherein the halves are connected by a pair of complementary latching elements.

5. The connector assembly of claim 2 , wherein the halves are sealed by an overlapping sealing structure.

6. The connector assembly of claim 1 , wherein the flange has a concavity facing the inner side of the wall.

7. The connector assembly of claim 6 , wherein the flange is deformed when in contact with the inner side of the wall.

8. The connector assembly of claim 1 , wherein the flange has a pair of fastening elements attaching the flange to the wall.

9. The connector assembly of claim 8 , wherein the fastening elements are protruding elements inserted in a plurality of additional cut-out holes surrounding the cut-out hole that receives the main connector body.

10. The connector assembly of claim 8 , wherein the fastening elements are integrally formed with the flange.

11. The connector assembly of claim 1 , wherein the flange has a plurality of lips extending with a rounded profile along the first direction.

12. The connector assembly of claim 1 , wherein the internal flap is inclined at least 60 degrees with respect to the lead-through channel.

13. The connector assembly of claim 1 , further comprising a cap having a conically narrowing middle section attached to the back portion of the protective shell.

14. The connector assembly of claim 1 , wherein the front portion of the shell and the back portion of the shell are arranged at a relative angle between 80 and 100 degrees.

15. The connector assembly of claim 14 , wherein the front portion of the shell and the back portion of the shell are arranged at a relative angle of 90 degrees.

16. The connector assembly of claim 1 , wherein the connector assembly is used in a refrigerator application.
