The present invention provides, in various embodiments, a push on cap for an electrical cable that can be both temporary and permanent. The cap includes an extension that can be folded back for temporary installation of the cap on the cable, and unfolded onto the cable for permanent installation.
1. A cap for covering an exposed end of a cable, wherein the cap is a push on cap, not a heat shrink cap or a cold shrink cap, the cap consisting essentially of an elastomeric rubber material and a sealing mastic both when temporarily installed on the cable and when permanently installed on the cable, the sealing mastic positioned on a middle section of the cap, wherein the cap is configured to provide an interference fit without engaging the sealing mastic when the cap is in a folded form and temporarily installed on the cable, and wherein the cap is configured to provide a water-tight seal using the sealing mastic when the cap is in an extended form and permanently installed on the cable, wherein when the cap is in the extended form and permanently installed on the cable it is irreversibly fixed to the end of the cable and would have to be cut off to be removed.
2. The cap of claim 1 , wherein the elastomeric rubber material comprises ethylene propylene rubber.
3. The cap of claim 1 , wherein the sealing mastic is bonded to the rubber.
4. The cap of claim 1 , wherein the sealing mastic is cured in an elastic state.
5. The cap of claim 1 , wherein the cap is configured for a secondary (low voltage) cable.
6. The cap of claim 1 , wherein in the folded form a portion of the cap is folded back exposing the sealing mastic.
7. The cap of claim 1 , wherein in the extended form the cap is unfolded onto the cable positioning the sealing mastic against the cable jacket.
8. A push on cap for a cable that can be both temporary and permanent, the cap consisting essentially of an elastomeric rubber material and a sealing mastic both when temporarily installed on the cable and when permanently installed on the cable, the elastomeric rubber material forming a cap body having a closed cap end; and an extension portion having a middle section and an end section, the middle section of the extension portion having the sealing mastic bonded to an inner surface thereof, and the end section of the extension portion including one or more pull tabs, wherein the extension portion is configured to be folded back over at least a portion of the cap body to expose the mastic when the cap is free or temporarily installed on the cable; and wherein the one or more pull tabs are configured to be pulled to unfold the extension portion onto the cable and seal the mastic thereto when the cap is permanently installed on the cable.
