Claims

[Claim 1] In an electrical isolation device (3) for a busbar (2), the electrical isolation device (3) for the busbar (2) comprises a support (4) made of an electrical insulating material configured to cover the busbar (2), and at least one detachable electrical insulating cover (5) attached to the support (4), - The support (4) comprises at least one opening (43) that can extend opposite to at least one fixing means (6) for fixing the busbar (2), and a guide slot (44) for guiding the at least one cover (5), - An electrical isolation device (3) for a busbar (2), characterized in that the at least one cover (5) comprises a body (51) and is slidably mounted on the support (4) via at least one guide member (52) connected to the body (51) so that it can move in the guide slot (44) between a first position in which the at least one opening (43) is not covered and a second position in which the at least one opening (43) is covered by the body (51). [Claim 2] The guide member (52) - A retaining member (53) for securing the cover (5) to the support (4), wherein the retaining member (53) comprises a deformable portion (53a) in particular in the form of a clip, configured to cooperate with at least one edge of the guide slot (44) to prevent the cover (5) from moving in at least one direction relative to the support (4), - The insulating device (3) according to claim 1, comprising: at least one positioning member (54) for positioning the cover (5) at at least one of the first position or the second position, wherein the guide slot (44) comprises at least one positioning element (45), such as a recess, having a shape that complements the shape of the positioning member (54) and demarcates the position. [Claim 3] The insulating device (3) according to claim 1 or 2, wherein the body (51) of at least one cover (5) is provided with a gripping promoting member (55, 55a) positioned on one end of the body (51) and configured to extend as a projection from the support (4) in at least one direction. [Claim 4] The insulating device (3) according to claim 1 or 2, comprising a plurality of covers (5), wherein the support (4) comprises a plurality of guide slots (44), and each of the slots is configured to cooperate with one of the plurality of covers (5). [Claim 5] The insulating device (3) according to claim 1 or 2, wherein the support (4) comprises at least one wall (41, 42) and at least one attached detachable portion (47) configured to be fixed to the at least one wall (41, 42), the detachable portion (47) comprising at least one opening (43) and the guide slot (44) for guiding the at least one cover (5). [Claim 6] The insulating device (3) according to claim 1 or 2, wherein the support (4) is provided with an anti-misassembly slit (71) that passes through the thickness of the support (4) and connects to the at least one opening (43), and the cover (5) is provided with an anti-misassembly means (72) that protrudes from the main body (51) and is configured to cooperate with the anti-misassembly slit (71) so as to extend through the anti-misassembly slit (71) and protrude from the support (4). [Claim 7] An electrical insulation assembly (1) for a busbar (2), comprising an insulating device (3) according to claim 1 or 2 and a busbar (2). [Claim 8] The electrical insulation assembly (1) according to claim 7, further comprising at least one fixing means (6) positioned opposite to the at least one opening (43) and mounted on the bus bar (2), wherein the fixing means (6) is a restraining screw. [Claim 9] - The support (4) is overmolded onto the busbar (2), or - The electrical insulation assembly (1) according to claim 7, further comprising an electrical insulation base plate (8) configured to cooperate with the support (4), wherein the base plate (8) extends at least to one side of the busbar (2) and the support (4) extends at least to the opposite side of the busbar (2) relative to the base plate (8). [Claim 10] A method for installing an electrical insulation assembly (1) according to claim 7, comprising positioning the busbar (2) on a module of an electrical energy storage device, positioning at least one fixing means (6) to fix the busbar (2) to the module, and moving the at least one cover (5) from the first position to the second position by sliding it against the support (4).
