The rubber insert features an outside structure to join with the inner surface of the plastic body, an inside structure to surround the cable, and a fitting rib along an outside surface of the outside structure, the fitting rib to occupy the receiving cavity. The inside structure of the rubber insert moves in response to movement of the cable while the outside structure does not move.

The invention relates to a power distribution unit (1), such as a fuse box for a vehicle, for providing a protected electrical connection between a power supply cable and a plurality of distribution cables (7). The unit comprises a housing (2) and, received in said housing: —a bus bar (5) configured to be connected to the power supply cable; —a plurality of fuses (10), each fuse comprising a body (15), a first end portion (11) configured to be connected to the bus bar (5), and a second end portion (12) configured to be connected to a distribution cable (7); —at least one retainer (20) for maintaining the bus bar (5) in position with respect to the housing (2); —at least one positioner (40) for positioning the fuse first end portion (11) relative to the bus bar (5) along directions (X, Y) substantially parallel to the bus bar; —a biasing member (30) configured to urge the fuse first end portion (11) towards the bus bar (5), to cause the fuse first end portion to remain in contact with the bus bar.

A safety fuse for use in a motor vehicle includes which fuse comprises a first contact metal portion, a second contact metal portion and a melting metal section connecting the first contact portion to the second contact portion. The melting section is enclosed by a casing made from a non-conductive material and includes two hollow half-shells provided with mutual coupling elements, each half-shell having an inner surface facing the melting section and an outer surface facing outside of the fuse. At least one of the half-shells is provided on at least part of the inner surface of an alveolar structure with open cells in the direction of the melting section. The alveolar structure is formed by a plurality of walls protruding from the inner surface and intersected with each other.

The invention concerns a fuse box, comprising a busbar (6) and at least one fuse (8) connected to the busbar, each fuse including two opposite end portions (8A, 8B) and a central portion (82), at least the central portion of each fuse and a section of the busbar being encapsulated in a plastic coating layer. The central portion (82) includes a part (84) of reduced cross-section. The two end portions (8A, 8B) include two respective electrical connectors (81A, 81B), and at least the two electrical connectors (81A, 81B) of each fuse (8) are not encapsulated in the plastic coating layer, so that a new fuse (12) can be connected between the two electrical connectors (81A, 81B) in replacement of a blown fuse (8).
