Abstract

Abstract A method for protectively enclosing electrical cables (10, 12) 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 (36) in communication with the housing interior, the pressure-relief valve (36) 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 (36). The encapsulant introduction step is practiced by providing a pump (40) 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 (44).

Claims Analysis

Total Claims: 7

Claim 1

Independent Claim 113 words

A method for protectively enclosing one or more electrical cables, comprising 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 40 words

A method as 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 3

Dependent Claim 45 words

A method as claimed in claim 1 or claim 2, 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 4

Dependent Claim 31 words

A method as claimed in claim 2, wherein said step B is further practiced by configuring said end plate means with a recess and inserting said cable seal in said recess.

Claim 5

Independent Claim 83 words

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, which method comprises 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 6

Dependent Claim 40 words

A method as claimed in claim 5, wherein said step B is practiced by providing a pump having an inlet and an outlet, placing said pump inlet in communication with said housing interior and supplying encapsulant to said pump inlet.

Claim 7

Dependent Claim 83 words

A method as claimed in claim 1, claim 2 or claim 4 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 further steps of: A. providing a pump having an inlet and an outlet and placing said pump outlet in communication with said housing interior; B. providing a bulk container of encapsulant; and C. supplying encapsulant to said pump inlet directly from said bulk encapsulant container.
