Abstract

The application relates to an electrical connection device ( 100 ) including a terminal block ( 10 ) adapted for connecting to a lug of an electrical cable. The terminal block ( 10 ) comprises a locking sleeve ( 3 ) adapted for securing the lug so as to enable translation between the terminal block ( 10 ) and the lug. The sleeve ( 3 ) comprises a first portion ( 1 ) and a second portion ( 2 ), as well as a pivot element ( 13, 14 ) configured such that the first and second portions ( 1, 2 ) pivot relative to one another. The pivot element comprises a pin ( 14 ) which is connected to the second portion ( 2 ) and engaged with the first portion ( 1 ) on the side of the first portion ( 1 ) substantially opposite the side of the first portion ( 1 ) facing the second portion ( 2 ). Advantageously, relative rotational is also allowed. A busbar is preferably connected to the terminal block.

First claim

What is claimed is:

1. Device for an electrical connection ( 100 ) including a terminal block ( 10 ) adapted for being connected to a lug ( 20 ) of an electrical cable ( 25 ), the terminal block ( 10 ) comprising a locking sleeve ( 3 ) adapted for securing the lug ( 20 ) in such a way as to form an electrical connection enabling relative movement between the terminal block ( 10 ) and the secured lug ( 20 ), characterised in that the locking sleeve ( 3 ) comprises a first portion ( 1 ) and a second portion ( 2 ), as well as a pivot element ( 13 , 14 ) configured such that the first and second portions ( 1 , 2 ) pivot relative to one another in order to allow for the introduction of the lug ( 20 ) and the securing thereof, in that the pivot element of the locking sleeve ( 3 ) comprises a pin ( 14 ) connected to the second portion ( 2 ) of the locking sleeve ( 3 ) and engaged with the first portion ( 1 ) of the locking sleeve ( 3 ) on the side of the first portion ( 1 ) substantially opposite the side of the first portion ( 1 ) facing the second portion ( 2 ) of the locking sleeve ( 3 ), and in that said relative movement allowed is translation.

2. Device for an electrical connection according to claim 1 , characterised in that the locking sleeve ( 3 ) of the terminal block ( 10 ) is configured to ensure a translation movement of the lug ( 20 ) over a limited length and for preventing the disconnection thereof of the locking sleeve ( 3 ) during translation.

3. Device for an electrical connection according to claim 1 , characterised in that said relative movement allowed further comprises rotation.

4. Device for an electrical connection according to claim 1 , characterised in that the pin ( 14 ) is located in a groove ( 11 ) formed in the first portion ( 1 ) of the locking sleeve ( 3 ), the pin ( 14 ) extending along an axis substantially perpendicular to an axis along which the terminal block extends substantially.

5. Device for an electrical connection as claim 1 , characterised in that the locking sleeve ( 3 ) has a shape that is complementary with that of the lug ( 20 ) in order to allow for engagement therewith.

6. Device for an electrical connection according to claim 5 , characterised in that the locking sleeve ( 3 ) defines a cylindrical space between the first and second portions ( 1 , 2 ), the locking sleeve ( 3 ) being adapted for enabling engagement with a lug ( 20 ) with a cylindrical rod ( 22 ) and an enlarged termination ( 23 ), and in that the rod ( 22 ) has a diameter less than that of the locking sleeve ( 3 ) and a length greater than that of the locking sleeve ( 3 ).

7. Device for an electrical connection as claimed in claim 1 , characterised in that the locking sleeve ( 3 ) comprises a fastening means ( 16 ) for the locking of the sleeve ( 3 ).

8. Device for an electrical connection as claimed in claim 1 , characterised in that it further comprises a busbar ( 12 ) connected to the terminal block ( 12 ) in order as such to form a terminal block and busbar assembly, and an electrical cable ( 25 ) with a lug ( 20 ), the lug ( 20 ) having a cylindrical rod ( 22 ) and an enlarged termination ( 23 ), and in that the rod ( 22 ) has a diameter less than that of the locking sleeve ( 3 ) and a length greater than that of the locking sleeve ( 3 ).

9. Electrical connection device and insulator assembly, characterised in that it comprises an electrical connection device ( 100 ) as claimed in claim 1 and an insulator ( 30 ), the electrical connection device ( 100 ) being arranged in the insulator ( 30 ), the insulator ( 30 ) being provided with walls ( 32 ), the walls ( 32 ) extending substantially parallel to the axis of the terminal block ( 10 ) and rising to a height greater than that of the terminal block ( 10 ).

10. Assembly according to claim 9 , characterised in that the insulator ( 30 ) comprises a cover ( 35 ) in order to encase the device ( 100 ).
