Abstract

Provided is an electric vehicle charger. The electric vehicle charger includes a lower case including a front partition wall having a cable penetration cutoff part that is cut to pass in forward and backward directions, an upper case including a front partition wall having a cable penetration cutoff part that is cut to pass in forward and backward directions, a sealing part having at least one portion disposed between the upper case and the lower case, and a cable passing though a portion of the upper case and a portion of the lower case, the cable being coupled between the upper case and the lower case.

First claim

What is claimed is:

1. An electric vehicle charger comprising:
a lower case comprising a first case protrusion, a first case groove, and a first front partition wall that is spaced at a distance from the first case protrusion, wherein the first case protrusion and the first front partition wall protrudes toward a center axis of a partition wall blocking part, and the first case groove is recessed toward a direction away from the center axis of the partition wall blocking part and is formed in the first front partition wall;
an upper case comprising a second case protrusion, a second case groove, and a second front partition wall that is spaced at a distance from the second case protrusion, wherein the second case protrusion and the second front partition wall protrudes toward the center axis of a partition wall blocking part, and the second case groove is recessed toward the direction away from the center axis of the partition wall blocking part and is formed in the second front partition wall;
a sealing part having at least one portion disposed between the upper case and the lower case; and
a cable coupled between the upper case and the lower case,
wherein the sealing part comprises:
the partition wall blocking part; and
a main sealing part connected to the partition wall blocking part,
wherein the partition wall blocking part comprises:
a cylindrical part having a through hole for insertion of the cable;
a plate protruding toward a direction away from the center axis of the partition wall blocking part;
a first sealing protrusion disposed spaced at a rear side of the plate and extending toward the direction away from the center axis of the partition wall blocking part;
a first sealing groove separately formed in each of an upper end of the plate and a lower end of the plate, wherein the first sealing groove is recessed toward the center axis of the partition wall blocking part to respectively receive the first case protrusion of the lower case and the second case protrusion of the upper case;
a second sealing groove disposed between the plate and the first sealing protrusion and recessed toward the center axis of the partition wall blocking part to insert the first front partition wall of the lower case and the second front partition wall of the upper case; and
a second sealing protrusion disposed within the second sealing groove, the second sealing protrusion being inserted into the first and second case grooves.

2. The electric vehicle charger according to claim 1 , wherein the sealing part further comprises:
a connection part extending inward from the main sealing part; and
a mounting sealing part having a ring shape, the mounting sealing part being disposed on an inner end of the connection part,
wherein the connection part and the mounting sealing part are integrated with the partition wall blocking part and the main sealing part.

3. The electric vehicle charger according to claim 1 ,
wherein the cylindrical part has a hollow cylindrical shape with front and rear ends opened, and
the front end of the cylindrical part communicates with a through hole of the plate.

4. The electric vehicle charger according to claim 3 , wherein a support protruding upward from a bottom surface of the lower case to the cylindrical part is disposed on the lower case.

5. The electric vehicle charger according to claim 2 , wherein a lower mounting part protruding upward and having an upper end that is recessed downward in a ring shape is disposed on the lower case, and
the mounting sealing part is disposed on an upper end of the lower mounting part.
