Abstract

The present invention relates to an assembly for the improved connection or termination of one or more minerally insulated cables, the assembly comprising an electrically insulating plate comprising one or more channels to accommodate and support one or more inward cables; one or more channels to accommodate and support one or more outward cables; one or more recesses to accommodate one or more electrical components; one or more terminal studs arranged to connect said at least one inward and outward cable; and a protective cover comprising one or more protective plates locatable over the electrically insulating plate and cables and further comprising one or more recesses located so as to provide access to each of the one or more terminal studs.

First claim

The invention claimed is:

1. An insulating connector for the connection of two or more cables or wires ( 16 , 50 ), the assembly comprising:
an electrically insulating block ( 42 ), said block ( 42 ) comprising:
one or more channels ( 52 ) to accommodate and support one or more inward cables ( 16 ), one or more of the inward cables comprising a minerally insulated cable;
one or more channels ( 52 ) to accommodate and support one or more outward cables ( 50 );
one or more recesses ( 52 ) to accommodate one or more electrical components ( 14 , 2 , 48 );
one or more terminal studs ( 12 ), each stud ( 12 ) arranged to connect said at least one inward and outward cable ( 16 , 50 ); and,
a cover ( 60 , 62 );
the cover ( 60 , 62 ) comprising one or more protective plates ( 64 , 66 ) locatable over the electrically insulating block ( 42 ) and cables ( 16 , 50 ), the protective plates ( 64 , 66 ) further comprising one or more recesses located so as to provide access to each of the one or more terminal studs ( 12 ).

2. An assembly as claimed in claim 1 wherein one or more of the protective plates ( 64 , 66 ) are comprised of an electrically insulating material.

3. An assembly as claimed in claim 1 wherein one or more of the protective plates ( 64 , 66 ) are of increased toughness relative to the protective cover ( 60 , 62 ) and/or electrically insulating block ( 42 ).

4. An assembly as claimed in claim 1 wherein one or more of the protective plates ( 64 , 66 ) additionally comprises a lid ( 68 ) which is fixedly attached to a substrate 36 .

5. An assembly as claimed in claim 4 wherein the lid ( 68 ) comprises a recess or cavity ( 74 ).

6. An assembly as claimed in claim 5 wherein the recess or cavity ( 74 ) is placed so as to allow access to each of the one or more terminal studs ( 12 ).

7. An assembly as claimed in claim 1 wherein said inward or outward cable ( 16 , 50 ) is bifurcated within a pot seal ( 14 ), said pot seal ( 14 ) being contained within a recess ( 52 ) formed within the electrically insulating block ( 42 ).

8. An assembly as claimed in claim 7 wherein said inward or outward cable ( 16 , 50 ) is thereon connected to one or more inward or outward conductors ( 46 ) protruding from said pot seal ( 14 ).

9. An assembly as claimed in claim 8 wherein said inward or outward conductors ( 46 ) are connected to said one or more terminal studs ( 12 ) by one or more connection terminals ( 44 ).

10. An assembly as claimed in claim 9 wherein said connection terminals ( 44 ) are comprised of ring tags ( 2 , 48 ), said ring tags ( 2 , 48 ) being arranged so that they may locate, in use, on respective terminal studs ( 12 ).

11. An assembly as claimed in claim 1 wherein the width of each channel ( 52 ) comprised within the insulating block ( 42 ) is approximately equal to or greater than the diameter of the cable ( 16 , 50 ) to be located, in use, in each respective channel ( 52 ).

12. An assembly as claimed in claim 1 wherein the width of each recess ( 52 ) comprised within the insulating block ( 42 ) varies to accommodate, in use, the respective pot seals ( 14 ), conductors ( 46 ), connection terminals ( 44 ) and ring tag ( 2 , 48 ) components.

13. An assembly as claimed in claim 1 wherein said one or more inward cables ( 16 ) are supported before entry into the assembly by a cable location and support feature.

14. An assembly as claimed in claim 1 wherein said one or more outward cables ( 50 ) are supported following exit from the assembly by one or more cable location and support features ( 54 ).

15. An assembly as claimed in claim 1 wherein the electrically insulating block ( 42 ) comprises at least a sufficient number of channels and/or recesses ( 52 ) to accommodate, in use, each cable ( 50 ) and electrical component ( 2 , 14 , 44 , 46 , 48 ).
