In an electric connection box, first and second holding structures between a casing and a terminal block outside the casing include locking portions provided on the side of an assembly surface of the casing, locked portions provided on the side of the terminal block and in which a relative movement of an installation target toward the side of an opening at an assembly completion position is locked by the locking portions, guide portions provided on the side of the assembly surface and extend along a direction of the relative movement between the locking portions and the locked portions in a state where the casing is attached to the installation target, and guided portions provided on the side of the terminal block and are guided from the side of the opening to the assembly completion position along the guide portions, respectively.

Electric connection box and wire harness

An electrical connection box can include a housing and a lower cover that closes a lower part of the housing in which the housing includes an electric wire bundle holder whose lower side open so as to be able to allow insertion of a bonder cap of an electric wire bundle in a state where the electric wire bundle is covered with the bonder cap. The lower cover includes a deep bottom part having a drainage hole. A shallow bottom part can be located above the deep bottom part below the electric wire bundle holder, with the shallow bottom part being formed to include an inclined surface inclined downward toward the deep bottom part, and a state where the bonder cap is inserted into the electric wire bundle holder is maintained on the inclined surface of the shallow bottom part on the lower cover.

An electric connection box includes: an insulating casing; at least one internal electric part that is accommodated inside the casing and is electrically connected to a plurality of internal electric wires drawn from the inside to the outside of the casing; and a terminal block that is provided with at least one external electric part electrically connected to at least one external electric wire and is assembled into the casing outside the casing. The casing includes an accommodation member that accommodates the internal electric part, and a removable member that is attached to and detached from the accommodation member. The terminal block includes a holding member that holds the external electric part. The holding member is formed as one part integrated with the removable member.

An electric junction box includes a fitting component to which an electronic component and an electric wire electrically connected to the electronic component are assembled, and a housing in which the fitting component is fitted and held. The fitting component includes a first peripheral wall forming an outer side face of the fitting component, a first bottom wall covering a lower opening of the first peripheral wall, a first drain hole provided in the first bottom wall, and a cylindrical drain portion protruding downward from an edge portion of the first drain hole in the first bottom wall.

Electric junction box

An electric connection box includes a fitting component having a peripheral wall, a housing having a fitting holding portion, a first water stop portion provided along a first opening end edge of the peripheral wall, a second water stop portion provided along a second opening end edge of the peripheral wall, and a guide lock. The guide lock guides the fitting component with respect to the fitting holding portion along an extending direction of the first opening end edge, and guides the fitting component by a fitting stroke distance along a fitting direction along the first opening end edge and the second opening end edge such that the fitting component is fitted and held. The fitting stroke distance is shorter than a length of the first water stop portion and the second water stop portion.
