A power distribution box assembly for a vehicle is provided. The power distribution box assembly includes a housing having a peripheral wall and an inner wall. The inner wall is dimensioned to hold electrical components. A cover is configured to cover the peripheral wall of the housing, and the cover has an interior surface. A first latching mechanism and a second latching mechanism are disposed opposite of the first latching mechanism. The first and second latching mechanisms are selectively operable between an engaged positon and a disengaged position. In the engaged position, the cover is closed onto the housing. A rib is disposed on a top surface of the inner wall of the housing. The rib abuts the interior surface of the cover when the first and second latching mechanisms are in the engaged position.

A power distribution panel for distributing power to a plurality of components. A modular frame may removably attach in an aperture of a side of a chassis. A first module may be removably attached in an opening of the modular frame. A second module, different from the first module, may be removably attached in the opening of the modular frame.

An electrical distribution block includes a first base, a second base, and a spacer plate discrete from the first and second base. The spacer plate is positioned between first base and the second base and secures the first base to the second base. A conductor block is connected to at least one of the first base or the second base. The conductor block includes a primary tap and a secondary tap.

A distribution box includes a box body, a cover plate, and at least one guiding rail. The box body has several side plates and a base plate. An opening is formed by surrounding an end of each side plate. The base plate is connected to another end of each side plate. The cover plate is detachably engaged with the box body and closes the opening. The guiding rail is disposed inside the box body and has an open end facing toward the opening. At least one electrical accessory slides into the guiding rail from the open end and is engaged with the guiding rail. With the open end facing toward the opening, the electrical accessory could be easily disassembled and assembled without reserving an installation space at a position adjacent to the open end for providing other electrical accessories, which provides an effect of saving installation space.

Provided is an electrical connection box 10 that includes a box main body 12 having a surface 14 provided with a component mounting portion 22 in which an electrical component 30 is mounted; and a cover member 16 covering the surface 14 of the box main body 12, in which an inner surface 48 of a top wall portion 42 of the cover member 16 is provided with a heat dissipation member holding portion 52 that protrudes toward the electrical component 30, and a plastic heat dissipation member 64 held by the heat dissipation member holding portion 52 is made to come into contact with a surface 66 of the electrical component 30.
