Abstract

An electric vehicle charger includes a case including a lower case having an opened top surface and in which a connector insertion groove is defined in a side surface thereof and an upper case having an opened bottom surface and covering the opened top surface of the lower case, a circuit board seated on the lower case and on which at least one electrical component of a short-circuit detection part detecting short-circuit of an electric vehicle, a detection part detecting overvoltage and overcurrent during charging of the electric vehicle, a communication module communicating with a charging control part of the electric vehicle, and a display part displaying a charged state of the electric vehicle is mounted, a cable inserted into the lower case, the cable being electrically connected to the circuit board, and a cable connector inserted into the connector insertion groove to guide the insertion of the cable.

Claims

1. An electric vehicle charger comprising:

a case comprising a lower case having an opened top surface and in which a connector insertion groove is defined in a side surface thereof and an upper case having an opened bottom surface and covering the opened top surface of the lower case;

a circuit board seated on the lower case and on which at least one electrical component of a short-circuit detection part detecting short-circuit of an electric vehicle, a detection part detecting overvoltage and overcurrent during charging of the electric vehicle, a communication module communicating with a charging control part of the electric vehicle, and a display part displaying a charged state of the electric vehicle is mounted;

a cable inserted into the lower case, the cable being electrically connected to the circuit board; and

a cable connector inserted into the connector insertion groove to guide the insertion of the cable, the cable connector preventing moisture from being introduced into the case.

2. The electric vehicle charger according to claim 1, wherein the cable connector comprises:

a connector body slideably inserted into the connector insertion groove;

a guide sleeve through which the cable passes, the guide sleeve extending from a front surface of the connector body; and

a bracket pushing an outer circumferential surface of the guide sleeve to fix the guide sleeve.

3. The electric vehicle charger according to claim 2, wherein the connector insertion groove is recessed downward from the top surface of the lower case by a predetermined depth, and

in a state where the connector body is completely inserted into the connector insertion groove, a top surface of the connector body is flush with that of the lower case.

4. The electric vehicle charger according to claim 3, further comprising a sealing member seated on the top surfaces of the lower case and the connector body,

wherein a lower circumference of the upper case is closely attached to the top surfaces of the lower case and the connector body.

5. An electric vehicle charger comprising:

a case comprising a lower case having an opened top surface and in which a connector insertion groove is defined in a side surface thereof and an upper case having an opened bottom surface and covering the opened top surface of the lower case;

a circuit board seated on the lower case and on which at least one electrical component of a short-circuit detection part detecting short-circuit of an electric vehicle, a detection part detecting overvoltage and overcurrent during charging of the electric vehicle, a communication module communicating with a charging control part of the electric vehicle, and a display part displaying a charged state of the electric vehicle is mounted;

a cable inserted into the lower case, the cable being electrically connected to the circuit board; and

a cable connector inserted into the connector insertion groove to guide the insertion of the cable, the cable connector preventing moisture from being introduced into the case,

wherein the cable connector comprises;

a waterproof packing fitted into the cable through hole;

a bracket fixed to the inside of the lower case in a state where the bracket covers a top surface of the waterproof packing; and

a waterproof cover covering a rear surface of the waterproof packing, the waterproof cover being fixed to a side surface of the lower case.

6. The electric vehicle charger according to claim 5, wherein a stepped portion on which the rear surface of the waterproof packing is seated is disposed on a front surface of the waterproof cover.

7. The electric vehicle charger according to claim 5, wherein a seat groove on which the waterproof cover is seated is defined in a side surface of the lower case, and

the cable through hole is defined in a central portion of the seat groove.

8. The electric vehicle charger according to claim 5, further comprising a sealing member seated on the top surface of the lower case.
