Abstract
Abstract A method for protectively enclosing electrical cables, wherein a portion of at least one cable is sealably disposed in the interior of a housing, includes the steps of placing a pressure-relief valve in communication with the housing interior, the pressure-relief valve being selected to pass an encapsulant therethrough on exposure to a predetermined pressure in said housing interior, and introducing an encapsulant under pressure into the housing interior until the encapsulant passes through the pressure-relief valve. The encapsulant introduction step is practiced by providing a pump having an inlet and an outlet, placing the pump inlet in communication with the housing interior and supplying encapsulant to the pump inlet directly from a bulk encapsulant container.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
In a method for protectively enclosing one or more electrical cables, the steps of: A. applying end plate means to a cable, said end plate means being predefined to have a cable passage therethrough and having a cable seal in said cable passage; B. sealably applying to said end plate means a housing enclosing said end plate means and defining a hollow interior; C. placing a pressure-relief valve in communication with said housing interior, said pressure-relief valve being selected to pass an encapsulant therethrough on exposure to a predetermined pressure in said housing interior; and D. introducing an encapsulant under pressure into said housing interior until said encapsulant passes through said pressure-relief valve.
Claim 2
Dependent Claim
113 words
In a method for protectively enclosing one or more electrical cables, the steps of: A. applying end plate means to a cable, said end plate means being predefined to have a cable passage therethrough and having a cable seal in said cable passage; B. sealably applying to said end plate means a housing enclosing said end plate means and defining a hollow interior; C. placing a pressure-relief valve in communication with said housing interior, said pressure-relief valve being selected to pass an encapsulant therethrough on exposure to a predetermined pressure in said housing interior; and D. introducing an encapsulant under pressure into said housing interior until said encapsulant passes through said pressure-relief valve.
Claim 3
Dependent Claim
39 words
The invention claimed in claim 1, wherein said step B is practiced in part by providing first and second elongate casings juxtaposable along respective end surfaces thereof and sealably mating said first and second casings at said end surfaces.
Claim 4
Dependent Claim
41 words
The invention claimed in claim 1, wherein said step D is practiced in part by providing a pump having an inlet and an outlet, placing said pump outlet in communication with said housing interior and supplying encapsulant to said pump inlet.
Claim 5
Dependent Claim
30 words
The invention claimed in claim 2, wherein said step B is further practiced by configuring said end plate means with a recess and inserting said cable sea-1 in said recess.
Claim 6
Dependent Claim
81 words
In a method for protectively enclosing one or more electrical cables wherein a portion of at least one cable is sealably disposed in the interior of a housing, the steps of: A. placing a pressure-relief valve in communication with said housing interior, said pressure-relief valve being selected to pass an encapsulant therethrough on exposure to a predetermined pressure in said housing interior; and B. introducing an encapsulant under pressure into said housing interior until said encapsulant passes through said pressure-relief valve.
Claim 7
Dependent Claim
