- the present invention relates to a filler assembly for cable glands and relates particularly, but not exclusively, to such a filler assembly for filling cable glands for use in hazardous areas.
- Many cable glands for use in connecting a cable to an enclosure in hazardous areas need to be filled with a compound which provides a barrier against the effects of an explosion occurring within the enclosure to which the cable gland is attached.
- the barrier is typically formed from a two-part clay-filled epoxy compound.
- the two component parts of the compound need to be thoroughly mixed with each other prior to fitting into the gland, and the resulting putty like material needs to be packed between the individual conductors in the cable.
- time of the putty like material is chosen to be relatively long, in order to enable it to be manipulated into the spaces between the individual conductors before curing becomes advanced.
- the filled cable assembly must be left undisturbed for a significant period, usually several hours, especially if mixed at low temperatures.
- the components of the filler material sometimes contain hazardous materials which become harmless when the filler material is mixed. Persons mixing the components of the putty like filler material may come into contact with these hazardous materials during mixing, and air can become trapped within the cable gland by the filler material which may cause the barrier formed by the filler material to fail in the event of an explosion. Filling of the cable gland is also relatively difficult, especially in the case of small cable glands.
- GB 765082 discloses an arrangement for insulating a splice between two stranded connectors in which resinous material is introduced from a capsule having an elongate tip.
- this arrangement suffers from the drawback that it is not suitable for filling cable glands, since the introduction of a material which is sufficiently fluid to penetrate between the individual conductors of a cable would cause material to flow along the conductors along the interior of the cable, which would prevent the cable gland from being sufficiently filled to expel all of the air from the cable gland to avoid air voids.

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.

- The present invention relates to a filler assembly for cable glands and relates particularly, but not exclusively, to such a filler assembly for filling cable glands for use in hazardous areas.
- Many cable glands for use in connecting a cable to an enclosure in hazardous areas need to be filled with a compound which provides a barrier against the effects of an explosion occurring within the enclosure to which the cable gland is attached. The barrier is typically formed from a two-part clay-filled epoxy compound. The two component parts of the compound need to be thoroughly mixed with each other prior to fitting into the gland, and the resulting putty like material needs to be packed between the individual conductors in the cable. Such an arrangement is disclosed in GB 2258350. time of the putty like material is chosen to be relatively long, in order to enable it to be manipulated into the spaces between the individual conductors before curing becomes advanced. As a result, the filled cable assembly must be left undisturbed for a significant period, usually several hours, especially if mixed at low temperatures. Also, the components of the filler material sometimes contain hazardous materials which become harmless when the filler material is mixed. Persons mixing the components of the putty like filler material may come into contact with these hazardous materials during mixing, and air can become trapped within the cable gland by the filler material which may cause the barrier formed by the filler material to fail in the event of an explosion.

-
FIG. 1 is a perspective view of a dispensing apparatus embodying the present invention. -
FIG. 2 . is a partially cut away perspective view of a cable gland having a filler formed using the apparatus ofFIG. 1 ; and -
FIG. 3 is a cross sectional view of the filled cable gland ofFIG. 2 with a thread protector in place. - Referring to
FIG. 1 , adispenser apparatus 2 embodying the present invention and for use in filling a cable gland 4 (FIG. 2 ) with curableliquid material 6 comprises a body of suitable transparent flexible plastics material defining aflexible bag 8 having afirst compartment 10 for accommodating a first component of a liquidcurable material 6, and asecond compartment 12 for accommodating a second component of thematerial 6. Afirst clamp 14 temporarily separates thefirst compartment 10 andsecond compartment 12 to thereby prevent mixing of the first and second components of thematerial 6. The first and second components are coloured differently (for example blue and yellow) so that thorough mixing of the first and second components produces a green liquid, thereby providing a visual indication when thorough mixing of the first and second components has occurred. Mixing of the first and second components together causes gelling of the material and initiates curing of the curableliquid material 6. - The
dispenser apparatus 2 is also provided with an elongatehollow nozzle 16 extending from thesecond compartment 12 such that dispensing of the mixed curable liquid material can be carefully controlled. In particular, thenozzle 16 can be inserted a considerable distance into thecable gland 4 and between individualcore conductors 20 of the core of acable 22 attached to the cable gland 4 (FIG. 2 ) so that theliquid material 6 can be highly flowable and fast-curing, as a result of which thecable gland 4 can be rapidly filled and air entrapment by theliquid material 6 minimised. Asecond clamp 18 temporarily prevents material flowing from thesecond compartment 12 into thenozzle 16, so that dispensing of thematerial 6 can be prevented until thorough mixing together of the first and second components has occurred. - The
flexible bag 8 is formed from two sheets of material welded together along all but one of their edges to form a bag having an open mouth, which is then mounted to thenozzle 16. Thesecond clamp 18 is then mounted to the bag adjacent to thenozzle 16, and the second component of thematerial 6 is dispensed into thesecond compartment 12. Thefirst clamp 14 is then mounted to the bag to seal the second component in thesecond compartment 12, and the first component is then dispensed into thefirst compartment 10. The open edge of the bag is then sealed to seal the first component in thefirst compartment 10. - Referring to
FIGS. 2 and 3 , thecable gland 4 to be filled by means of thedispenser apparatus 2 ofFIG. 1 comprises a threadedouter connector 24 for threaded connection to an enclosure (not shown) and acompound tube 26 rotatably mounted within theouter connector 24. Acable connector 28 is mounted to the end of thecable 22 and is connected to theouter connector 24 by means of cooperating screw threads (not shown). - A
ring 30 abuts thecable connector 28 and aflexible seal 32 is located around thecore conductors 20 of thecable 22 and compressed between thecompound tube 26 and ring 3 0 for limiting the extent of penetration ofcurable material 6 into thecable gland 4 before curing of thecurable material 6. Theflexible seal 32 comprises a generally frusto-conical body of elastomeric material having an aperture (not shown) therethrough for engaging thecore conductors 20 of thecable 22. The aperture in theseal 32 is sized such that it stretches to pass around thecore conductors 20 to tightly engage thecore conductors 20 to form a reasonably effective barrier to passage of thetrtaterial 6 along the space defined between thecore conductors 20 and thecompound tube 26. - Referring to
FIG. 3 , athread protector 34 formed of elastomeric material such as rubber is located over the external screw thread of theouter connector 24 of thecable gland 4 prior to filling of the cable gland withcurable material 6. Thethread protector 34 has ahollow rim 36 for catching excesscurable material 6 which may flow out ofend 40 of thecable gland 4 during the filling procedure, and an innercircular rim 38 which prevents penetration ofcurable material 6 into the gap between theouter connector 24 and thecompound tube 26. This ensures that thecompound tube 26 complete withcable connectors 28 can be removed from theouter connector 24 after curing of thematerial 6. - The process of filling the
cable gland 4 ofFIGS. 2 and 3 by means sof thedispenser apparatus 2 ofFIG. 1 will now be described. - In order to fill the core of the
cable gland 4 with curable material, theflexible seal 32 initially placed over thecore conductors 20 of thecable 22 so that theseal 32 tightly grips thecore conductors 20. Theouter connector 24 withcompound tube 26 are then mounted to thering 30 andcable connector 28 to compress theseal 32 between thering 30 andcompound tube 26. As a result, theflexible seal 32 acts as a barrier to penetration of the curableliquid material 6 into the interior of thecable gland 4. - The
first clamp 14 is then removed from thedispenser apparatus 2 and thesecond clamp 18 left in place, to enable thorough mixing of the first and second components of the curableliquid material 6. The first and second components are coloured blue and yellow respectively, a result of which the curableliquid material 6 is bright green when it is thoroughly mixed. Thesecond clamp 18 is then removed, and the outlet of thenozzle 16 is placed at a location near theseal 32. Theliquid material 6 is then dispensed through thenozzle 16 into the space between thecore conductors 20 of thecable 22 and into the space around thecore conductors 20 inside thecompound tube 26 of thecable gland 4, where its movement along thenozzle 16 near theseal 32 causes air to be expelled from the cable gland when the curableliquid material 6 is dispensed from thenozzle 16. Theseal 32 provides a sufficient barrier to penetration of thematerial 6 to hold hack the curable material until it begins to gel and support itself. At the same time, thethread protector 34 protects the external thread of theouter connector 24 from excess curable material and prevents penetration of the liquid curable material between theouter connector 24 and thecompound tube 26. Thematerial 6 is arranged to change colour to dark green when it is cured, so that a visual indication is provided when the curing process is completed. - It will be appreciated by persons skilled in the art that the above embodiment has been described by way of example only, and not in any limitative sense, and that various alterations and modifications are possible without departure from the scope of the invention as defined by the appended claims.
