Abstract

Waterproof apparatus for cables and cable interfaces are provided herein. An exemplary apparatus includes a coupler body that includes a first end configured to releaseably couple with a connector bulkhead and a second end having an opening that is sized to receive a sealing gland, a cavity for receiving the sealing gland, the sealing gland comprising an outer peripheral surface configured to sealingly engage with an inner surface of the cavity, the sealing gland comprising an aperture that is configured to receive a cable.

Claims

1. An apparatus, comprising a coupler body that includes a first end configured to releaseably couple with a connector bulkhead and a second end having an opening that is sized to receive a sealing gland, and a cavity for receiving the sealing gland, the sealing gland comprising an outer peripheral surface configured to sealingly engage with an inner surface of the cavity, the sealing gland comprising an aperture that is configured to receive a cable, wherein the sealing gland is an annular member having a slit that allows a cable to pass therethrough when the sealing gland is pressed onto the cable, allowing the sealing gland to encircle the cable in a waterproof manner, wherein the sealing gland comprises a first surface and a second surface formed by the slit, the first and second surfaces touching one another after the cable passes through the slit due to resiliency of the sealing gland.

2. The apparatus according to claim 1, further comprising a sealing gasket associated with the first end of the coupler body, the sealing gasket forming a waterproof seal between the first end of the coupler body and the connector bulkhead.

3. The apparatus according to claim 1, wherein the coupler body further comprises:

a plurality of tabs that extend from the second end of the coupler body, the plurality of tabs forming a recess that receives the sealing gland; and

a coupler cap that is configured to releaseably engage with the second end of the coupler body, the coupler cap having a domed profile with an angled inner sidewall that engages with ends of the plurality of tabs to compress the plurality of tabs against the sealing gland when the coupler cap is engaged with the second end.

4. The apparatus according to claim 3, wherein each of the plurality of tabs is arcuate.

5. The apparatus according to claim 3, wherein the coupler cap comprises a frusto-conical inner sidewall.

6. The apparatus according to claim 1, wherein the first end comprises a bayonet arrangement that lockingly engages with the connector bulkhead.

7. The apparatus according to claim 1, wherein the cable comprises any of Category 5E, Category 6, Category 7, and Category 7 Direct Burial.

8. The apparatus according to claim 1, wherein the sealing gland comprises a closed cell foam.

9. A method for waterproofing a pre-terminated cable and connector, the method comprising:

threading the pre-terminated cable and the connector through a coupler cap having an angled inner sidewall;

placing a sealing gland around the pre-terminated cable by pressing the pre-terminated cable through a slit, allowing the sealing gland to encircle the cable in a waterproof manner, the sealing gland comprising a first surface and a second surface formed by the slit, the first and second surfaces touching one another after the cable passes through the slit due to resiliency of the sealing gland;

threading the pre-terminated cable and the connector into a coupler body that includes a first end configured to releaseably couple with a connector bulkhead and a second end having a plurality of tabs that form a recess;

disposing the sealing gland within the recess; and

engaging the coupler cap with the second end of the coupler body such that the plurality of tabs are compressed against the sealing gland by the angled inner sidewall of the coupler cap.

10. The method according to claim 9, further comprising:

associating a sealing gasket with the first end of the coupler body; and

coupling the first end of the coupler body with a bulkhead connector, the sealing gasket forming a waterproof barrier between the first end and the bulkhead connector.

11. The method according to claim 9, further comprising pre-terminating the cable by coupling the cable with the connector.

12. The method according to claim 9, wherein placing a sealing gland around the pre-terminated cable comprises aligning a section of the cable with the slit of the sealing gland;

and pushing the sealing gland from an outer peripheral sidewall of the sealing gland through the slit and onto the section of the cable so that the section of cable is surrounded by an inner sidewall of the sealing gland.
