Waterproof structure of electric junction box
View Patent ↗A first cover body has a first space defined by peripheral walls. Each of a plurality of protruded portions has a through hole, and is outwardly protruded from at least one of the peripheral walls so as to define a groove communicated with the first space and the through hole. Each of a plurality of retainers is provided with one of the protruded portions. A second cover body is fitted with the first cover body so as to close the first space, while being retained by the retainers. A plurality of projections are provided on an outer periphery of a third cover body. The third cover body is disposed in the first space such that each of the projections is fitted into the groove so as to partition the first space from the through hole.
1. An electric junction box, comprising:
a first cover body, having a first space defined by peripheral walls;
a plurality of protruded portions, each having a through hole, and outwardly protruded from at least one of the peripheral walls so as to define a groove communicated with the first space and the through hole;
a plurality of retainers, each provided with one of the protruded portions;
a second cover body, fitted with the first cover body so as to close the first space, while being retained by the retainers; and
a third cover body, comprising a plurality of projections provided on an outer periphery thereof, the third cover body being disposed in the first space so as to divide the first space into an upper region located between the third cover body and the second cover body and a lower region located below the third cover body, such that each of the projections is fitted into the groove so as to partition the upper region of the first space from-the through hole.
2. The electric junction box as set forth in claim 1 , wherein each of the retainers is a retaining projection formed in the groove so as to extend toward the first space.
3. The electric junction box as set forth in claim 1 , further comprising:
a first electric equipment, disposed between the first cover body and the third cover body; and
a second electric equipment, disposed between the second cover body and the third cover body.
