Abstract

A cable-gland system provides a sealing function to openings in an electronic chassis that receive cables. The cable-gland system comprises a plurality of individual cable glands. Each of the plurality of individual cable glands includes an exterior end to be positioned adjacent an exterior of the chassis, and an interior end for positioning within the chassis. Each of the plurality of individual cable glands includes a through-hole extending between the exterior and interior ends for receiving one of the cables, and an outer surface between the exterior and interior ends. Each of the plurality of individual cable glands has a male projection on one side of the outer surface and a female recess on an opposing side of the outer surface. The cable glands are connectable to form the cable-gland system by mating the male projection on one cable gland with the female recess of an adjacent cable gland.

First claim

What is claimed is:

1. A cable-gland system for sealing openings that receive cables in an electronic chassis, the cable-gland system comprising:
a plurality of individual cable glands, each of the plurality of individual cable glands including an exterior end to be positioned adjacent an exterior of the electronic chassis, an interior end for positioning within the electronic chassis, a through-hole extending between the exterior and interior ends for receiving one of the cables, and an outer surface between the exterior and interior ends, each of the plurality of individual cable glands having a male projection on one side of the outer surface and a female recess on an opposing side of the outer surface; and
wherein the plurality of individual cable glands is configured to be connected to form the cable-gland system by mating the male projection on one cable gland with the female recess of an adjacent cable gland;
wherein each of the plurality of individual cable glands has a registration feature for mating within a corresponding feature in the electronic chassis, the registration feature being positioned in a central area between the exterior end and the interior end, the male projection and the female recess being positioned between the exterior end and the registration feature.

2. The cable-gland system of claim 1 , wherein the registration feature is a projection extending away from the outer surface for mating within a corresponding recess in the electronic chassis.

3. The cable-gland system of claim 1 , wherein the through-holes in the individual cable glands have different internal diameters for receiving cables of different sizes.

4. The cable-gland system of claim 1 , wherein each of the plurality of individual cable glands includes a front annular groove adjacent to the exterior end, the front annular groove configured to receive a corresponding portion of the electronic chassis.

5. The cable-gland system of claim 4 , wherein the exterior ends of the plurality of individual cable glands protrude outside of the electronic chassis.

6. The cable-gland system of claim 1 , wherein each of the plurality of individual cables further includes an O-ring adjacent to the interior end for assisting with sealing the cable gland within the electronic chassis.

7. The cable-gland system of claim 1 , wherein each of the plurality of individual cable glands is generally cylindrical, the male projection is located on a first platform extending away from the one side of the outer surface, the female recess is located on a second platform extending away from the opposing side of the outer surface.

8. The cable-gland system of claim 1 , wherein the male projections of the plurality of individual cable glands and the female recesses of the plurality of individual cable glands form a snap-fit connection.

9. The cable-gland system of claim 1 , wherein each of the plurality of individual cable glands is interchangeable within the cable-gland system such that locations of two individual cable glands within the cable-gland system can be exchanged.
