Filler assembly for cable gland

Abstract

A dispenser apparatus for a curable liquid material is disclosed. The apparatus comprises a flexible bag defining a first compartment for accommodating a first component of a curable liquid material, and a second compartment for accommodating a second component of the curable liquid material and adapted to communicate with the first chamber to enable mixing of the first and second components to initiate curing of the curable liquid material. A first clamp temporarily prevents mixing of the first and second components, and an elongate nozzle communicates with the second compartment to dispense the mixed curable liquid material therefrom. A second clamp temporarily prevents passage of the curable liquid material from the second compartment to the nozzle.

         4 . An assembly according to  claim 1 , wherein the at least one seal spreads around the cores of the cable to surround the cores of the cable. 
     
     
         5 . An assembly according to  claim 1 , wherein the at least one seal is formed of an elastomeric materials. 
     
     
         6 . An assembly according to  claim 5 , wherein the elastomeric materials are flexible structures. 
     
     
         7 . The assembly according to  claim 6 , wherein the ring engages the at least one seal wherein the elastomeric materials extend radially inward from the ring. 
     
     
         8 . An assembly according to  claim 6 , wherein the elastomeric materials of the at least one seal form an opening that tightly grips the plurality of cores of the cable. 
     
     
         9 . An assembly according to  claim 6 , wherein the elastomeric materials return to an original shape when the cores are removed from the interstice. 
     
     
         10 . An assembly according to  claim 6 , wherein the ring abuts a cable connector, wherein the cable connector is connected to a threaded outer connector. 
     
     
         11 . An assembly according to  claim 10 , further comprising a thread protector disposed on the threaded outer connector, the thread protector configured to catch an excess curable liquid material. 
     
     
         12 . A filler assembly for filling a cable gland with curable liquid material, the assembly comprising:
 (a) a two-chamber dispenser apparatus for a curable liquid resin compound for creating a barrier to an explosion, the apparatus comprising:   a body defining at least one first chamber accommodating a first component of a curable liquid resin compound, and at least one second chamber accommodating a second component of said curable liquid resin compound, wherein mixing of said first and second components initiates curing of said curable liquid resin compound; and at least one dispenser device adapted to dispense said mixed curable liquid material therefrom between a plurality of said cores of said cable; and   (b) at least one seal having at least one aperture therethrough and adapted to provide a barrier to passage of said curable liquid material along the plurality of said cores of said cable, wherein the at least one seal is secured between a ring and a tube.   
     
     
         13 . An assembly according to  claim 12 , wherein said body is sufficiently flexible to enable manipulation of said curable liquid material through said body. 
     
     
         14 . An assembly according to  claim 12 , wherein the at least one seal comprises a flexible structure, wherein the flexible structure comprises a flexible member. 
     
     
         15 . An assembly according to  claim 14 , wherein the flexible structure is formed of an elastomeric material to form a space that tightly grips the plurality of the cores of the cable. 
     
     
         16 . An assembly according to  claim 15 , the flexible structure that forms the space tends to return to its original shape when the cores are removed from a mouth. 
     
     
         17 . An assembly according to  claim 15 , wherein the flexible structure tightly grips the plurality of the cores of the cable. 
     
     
         18 . An assembly according to  claim 15 , wherein the flexible structure that forms the space spreads around the cores of the cable to engage the cores of the cable. 
     
     
         19 . An assembly according to  claim 12 , further comprising a thread protector disposed on a threaded outer connector. 
     
     
         20 . An assembly according to  claim 19 , wherein the thread protector is configured to catch an excess curable liquid material.
