Abstract:
1. A waterproof structure comprising: one case; an other case; one connector fixed to a mounting hole of the one case; an other connector fixed to a mounting hole of the other case, the one connecter being constructed to be connected to the other connector; a ring-shaped first packing provided between a surface of the one case and a surface of the one connector and extending such that the mounting hole of the one case is surrounded thereby, the first packing being constructed to keep waterproof an interface between the one case and the one connector, wherein the surfaces of the one case and the one connector extend orthogonal to a fitting direction of the one connector with the other connector such that the interface between the one case and the one connector is defined by the surfaces of the one case and the one connector; and a ring-shaped second packing provided between a surface of the other case and an outer circumferential surface of the other connector such that the second packing extends on the outer circumferential surface of the other connector, the second packing being constructed to keep waterproof an interface between the other case and the outer circumferential surface of the other connector, wherein the surface of the other case and the outer circumferential surface of the other connector extend parallel to the fitting direction such that the interface between the other case and the other connector is defined by the surface of the other case and the outer circumferential surface of the other connector, wherein one of the one connector and the other connector includes a terminal accommodating portion configured to accommodate a terminal and an outer housing fixed to a corresponding one of the one case and the other case, the outer housing being provided in a shape of a cylinder having a bottom and opening toward another of the one connector and the other connector, the outer housing being configured to accommodate therein the terminal accommodating portion movably in the direction orthogonal to the fitting direction; a recess is provided in a shape of a dent on an inner bottom surface of the outer housing and positioning therein the terminal protruding from the terminal accommodating portion; and a ring-shaped fourth packing is provided between the inner bottom surface of the outer housing and the terminal accommodating portion and is adapted to keep waterproof an interface between the inner bottom surface of the outer housing and the terminal accommodating portion, wherein the recess is surrounded by the fourth packing.
