Waterproof structure of electtrical terminal box

Abstract

To provide the waterproof structure of an electric connection box which can be surely waterproofed. A part of an outer wall 24a is swelled to provide swelled parts 25a, 25b, thereby realizing preventing of water from dropping on a part which is influenced by scattered water, such as a fuse plate, a connector block, etc. That is, since the side wall 24a of the box is extended so as to cross the scattered water over the influenced part, the water drops down along the extended side wall 24a. Or, since the swelled parts 25a, 25b shut off or turn the flow of the water, the water is prevented from being flooded into the interior along the outer wall by a capillarity. (C)2005,JPO&NCIPI.

Description

technical field [0001] The invention relates to a waterproof structure of an electric junction box. Background technique [0002] Generally, electrical junction boxes used for electric circuits of automobiles are often placed in the engine compartment, but they may also be placed in the vehicle. At this time, although the situation of directly spraying water is rare, when the current popular wet cleaning (washing) in the car, or when drinking or splashing the condensed water flowing from the air-conditioning duct when eating in the car, it is necessary It will be required to prevent water from entering the car. [0003] The use of O-rings is considered for good waterproof performance, but this requires grooves corresponding to the O-rings to be formed on the body and cover parts. Thus, problems such as an increase in mold cost, an increase in the number of parts due to the use of the O-ring, and an increase in assembly man-hours are incurred. [0004] In view of the probl...

Problems solved by technology

[0014] However, although the above-mentioned junction box 200 can realize the waterproof effect of preventing water dripping from above when the upper box part 210 is installed to cover the lower box part 220 from above, when the contact surface of the upper box part 210 and the lower box part 220 When used as a vertical surface, there will be little problem of achieving waterproof effect
