Abstract

A sealing and strain relief device having at least one sealing element is disclosed. The device is arranged in the manner of a sandwich between outer, plate-like bearing elements made from a relatively hard or rigid material and which is made from a relatively soft or elastic material. Slots are introduced both into the outer bearing elements and into the or each central sealing element in such a way that the slots run respectively next to one another and respectively one behind the other, in relation to the sandwich-like arrangement thereof, within the respective bearing element and within the respective sealing element. The strain relief elements are associated with at least one plate-like bearing element such that each data cable, which is sealed and is guided in the region of slots arranged one behind the other of the sandwich-like arrangement, can be restrained using a strain relief element.

Claims

1. A sealing and strain relief device for data cables, comprising:

at least one central sealing element made from a relatively soft or elastic material;

two plate-like bearing elements made from a relatively hard or rigid material, wherein the at least one central sealing element is assembled in a sandwich-like arrangement between the two plate-like bearing elements;

a plurality of slots in the two bearing elements and the at least one central sealing element, wherein the slots are respectively next to one another and respectively one behind the other within respective ones of the two bearing elements and within the at least one central sealing element in relation to the sandwich-like arrangement; and

a plurality of strain relief elements associated with at least one of the two bearing elements,

wherein the sandwich-like arrangement of the at least one central sealing element and the two bearing elements with the strain relief elements is configured to seal and strain relief data cables guided in the slots perpendicular to the at least one central sealing element and the two plate-like bearing elements.

2. The sealing and strain relief device of claim 1, wherein the strain relief elements are associated exclusively with one of the two bearing elements.

3. The sealing and strain relief device of claims 1, wherein the strain relief elements are fixed releasably on the respective ones of the two bearing elements.

4. The sealing and strain relief device of claims 1, wherein each of the plurality of strain relief elements has a plate-like basic body, and wherein when one of the plurality of the strain relief elements has been fastened on the respective one of the two bearing elements, the strain relief element is perpendicular to the bearing element.

5. The sealing and strain relief device of claim 4, wherein the plate-like basic body of each strain relief element has a rail-like guide element on at least one of a first side and a first end, allowing the strain relief element be fixed on one of the two bearing elements via the guide element, and wherein the plate-like basic body of each strain relief element has receptacles for data cables on the at least one of the second side and the second end.

6. The sealing and strain relief device of claim 5, wherein the plate-like basic body of each strain relief element inserts into a groove-like guide element of one of the two plate-like bearing element via the respective rail-like guide element.

7. The sealing and strain relief device claims 4, wherein the plate-like basic body of each of the plurality of strain relief elements, when inserted into one of the two bearing elements is latched with the bearing element via a barb-like anchoring element of the bearing element, which barb-like anchoring element latches into a cutout in the plate-like basic body of each strain relief element.

8. The sealing and strain relief device of claims 1, wherein the central sealing element protrudes laterally with respect to the two bearing elements.

9. The sealing and strain relief device of claim 8, wherein each of the at least one central sealing element protrudes on four sides of the two bearing elements.

10. The sealing and strain relief device of claim 1, wherein each of the at least one central sealing element protrudes on at least one side of the two bearing elements.

11. A sealing and strain relief device for data cables, comprising:

at least one central sealing element made from a relatively soft or elastic material;

two plate-like bearing elements made from a relatively hard or rigid material, wherein the at least one central sealing element is assembled in a sandwich-like arrangement between the two plate-like bearing elements;

a plurality of slots in the two bearing elements and the at least one central sealing element, wherein the slots are respectively next to one another and respectively one behind the other within respective ones of the two bearing elements and within the at least one central sealing element in relation to the sandwich-like arrangement; and

a plurality of strain relief elements associated with at least one of the two bearing elements,

wherein the sandwich-like arrangement of the at least one central sealing element and the two bearing elements with the strain relief elements is configured to seal and strain relief data cables guided in the slots; and

wherein the central sealing element protrudes laterally with respect to the two bearing elements.

12. The sealing and strain relief device of claim 11, wherein each of the at least one central sealing element protrudes on four sides of the two bearing elements.

13. A sealing and strain relief device for data cables, comprising:

at least one central sealing element made from a relatively soft or elastic material;

two plate-like bearing elements made from a relatively hard or rigid material, wherein the at least one central sealing element is assembled in a sandwich-like arrangement between the two plate-like bearing elements;

a plurality of slots in the two bearing elements and the at least one central sealing element, wherein the slots are respectively next to one another and respectively one behind the other within respective ones of the two bearing elements and within the at least one central sealing element in relation to the sandwich-like arrangement; and

a plurality of strain relief elements associated with at least one of the two bearing elements,

wherein the sandwich-like arrangement of the at least one central sealing element and the two bearing elements with the strain relief elements is configured to seal and strain relief data cables guided in the slots; and

wherein each of the at least one central sealing element protrudes on at least one side of the two bearing elements.
