Abstract

The electric junction box includes: a wiring board; a connector block having a body part and terminals, the terminal penetrating through a bottom wall of the body part and one end part of the terminal being electrically connected to the wiring board; a case which is arranged above the bottom wall of the body part, has holes each of which allows an opposite end part of the terminal to pass therethrough so as to expose the terminal, and receives the wiring board and the connector block therein; and a drain part provided on an inner surface of the case so that water, which enters into the case from the hole and is drained from the connector block, moves downward along the inner surface of the case and is drained outside the case.

Claims

1. An electric junction box comprising:

a wiring board;

a connector block having a body part and terminals, the terminal penetrating through a bottom wall of the body part and one end part of the terminal being electrically connected to the wiring board;

a case which is arranged above the bottom wall of the body part, has holes each of which allows an opposite end part of the terminal to pass therethrough so as to expose the terminal, and receives the wiring board and the connector block therein; and

a drain part provided on an inner surface of the case so that water, which enters into the case from the hole and is drained from the connector block, moves downward along the inner surface of the case and is drained outside the case.

2. The electric junction box according to claim 1, wherein the wiring board is arranged in a vertical direction in the case and the drain part is provided at least in a range of from above an upper end of the wiring board to below a lower end of the wiring board.

3. The electric junction box according to claim 1, wherein the drain part is a first rib projecting from the inner surface of the case.

4. The electric junction box according to claim 3, wherein a plurality of the first ribs are provided.

5. The electric junction box according to claim 3, wherein a second rib is provided in the proximity of an upper end part of the first rib, the upper end part facing the connector block.

6. The electric junction box according to claim 1, wherein the drain part is a groove denting from the inner surface of the case.
