Abstract

PROBLEM TO BE SOLVED: To suppress a water from penetrating an electric connection box from the external through an opening portion for passing therethrough a wire harness, without manufacturing newly any metallic mold for the conventional constituent members of the electric connection box. SOLUTION: In a lower-side cover 12 having a notch-form opening portion 22 for passing therethrough a wire harness W, there are provided a right-side rib 23 along both a right-side end 21a of a sidewall 21 forming the opening portion 22 and an inside bottom surface 20a and a left-side rib 24 along both a left-side end 21b of the sidewall 21 and the inside bottom surface 20a. The lower-side cover 12 is so formed that the position of the lower end of the opening portion 22 is made lower than the one of the inside bottom surface 20a. Also, a draining structure for draining a water from the inside bottom surface 20a is provided in both the ribs 23, 24. Further, both the ribs 23, 24 are so formed in the state wherein they are superimposed on each other in the opening direction orthogonal to the opening surface of the opening portion 22 as to choke the clearance between the lower side of the opening portion 22 and a wire harness W. Moreover, a draining path 25 along the inside bottom surface 20a is formed between both the ribs 23, 24.

2. Description of the Related Art Conventionally, as shown in FIG. 5, a relay box is provided with a main body 51 having a substantially flat connecting portion 50, and the connecting portion 50 is provided with a plurality of relay mounting holes (not shown). Each relay mounting hole has a lower portion serving as a terminal fixing portion into which a female terminal to which each wire of the wire harness W is connected is inserted and fixed, and an upper portion thereof is electrically connected to the female terminal. The cavity in which the relay 52 is fixed is formed.

The upper side of the main body 51 is covered with an upper cover (not shown) together with the relay 52 mounted in each cavity.
The lower side of the main body 51 is covered with a lower lid 54 having an opening 53 through which the wire harness W passes, together with the female terminals inserted and fixed in each terminal fixing portion. The main body 51, the upper lid, and the lower lid 54 are each integrally formed of synthetic resin. The upper lid and the lower lid 54 are formed to have a substantially uniform thickness in order to minimize a dimensional change due to molding.

There is a possibility that water enters the main body 51 from above. In addition, water may adhere to each female terminal due to condensation. If water accumulates inside the relay box, a problem such as short circuit or electric leakage occurs. Therefore, it is necessary to discharge water from the inside of the relay box. For this reason, the lower lid 5
4 is provided with a drain hole for discharging water from the inside. The drain hole is also commonly used by the opening 53. When draining the water inside from the opening 53, the lower lid 54 is formed such that the bottom plate 57 is inclined toward the opening 53, as shown in FIG. 5.

However, since the cross section of the wire harness W is substantially circular, a relatively large gap is formed between the wire harness W and the lower side of the opening 53 cut out in a square shape. . However, when water is splashed from outside toward the opening 53 of the relay box, it is conceivable that water may enter the inside of the relay box through a gap between the lower side of the opening 53 and the wire harness W. .

It is conceivable to change to a bottom plate 57 having a groove-like cross-sectional shape that conforms to the shape shown in FIG. The discharge of water from the inner bottom surface 57a can be performed by providing a small drain groove at the bottom of the groove. However, for this purpose, it is necessary to newly manufacture a molding die for the lower lid 54, which leads to an increase in the unit cost of parts.
