As environmental issues have recently become an issue, eco-friendly vehicles have emerged as a target for energy conservation and environmental pollution minimization. In particular, hydrogen fuel cell vehicles, biodiesel vehicles, electric vehicles, etc. have been attracting attention as a replacement for vehicles composed of existing internal combustion engines.

Among them, an electric vehicle is a vehicle that moves using electricity, and refers to a vehicle that stores electric energy in batteries and uses it as a raw material. Electric vehicles can be divided into electric vehicles (EVs), plug-in hybrid EVs (PHEVs), and hybrid EVs (HEVs) according to the usage method and utilization rate of electric energy.

First, HEV (Hybrid EV) is a vehicle that combines two types of power from an internal combustion engine and an electric motor, and is characterized by realizing higher fuel economy and higher efficiency than conventional internal combustion engine vehicles. PHEV (Plug-in Hybrid EV) refers to a vehicle designed to charge and use the HEV battery from outside, and EV (Electric Vehicle) refers to a vehicle driven only by a battery and an electric motor.

In particular, HEV, PHEV, and EV vehicles commonly use electric energy to drive vehicles. HEV uses electric energy to be generated and used in vehicles, and PHEV and EV are supplied with power from the outside. Electric vehicles that are supplied with electric power from the outside are provided with a fast charging unit and a slow charging unit for charging a battery.

The battery of the electric vehicle can be charged by a quick charger or a slow charger. A quick charger is a charger that converts and uses 380V power of three-phase alternating current to direct current, and can finish charging the battery within 30 minutes. The quick charger is used in connection with the rapid charging part of the electric vehicle, and is directly connected to the battery of the electric vehicle to apply electric energy.

On the other hand, a slow charger is a charger that uses a 220V power source of single-phase AC and takes about 6 hours to charge the battery. The slow charger is used by connecting to the slow charging part of the electric vehicle, and applies electric energy to the battery through a converter that converts AC power into DC power inside the electric vehicle.

Due to the recent increase in commercial electric vehicles, the charging infrastructure problem of electric vehicles has become an issue. Quick chargers for electric vehicles are usually installed at gas stations or charging stations dedicated to electric vehicles, and slow chargers are built in places where parking is expected for a long time, such as in parking lots or shopping malls. Both fast and slow chargers are designed to be charged regardless of battery manufacturer and type.

At this time, the reason that the handle 130 is provided to protrude the other side of the latch 106, the other side of the latch 106 is pressed by an external force, the latch 106 seesaw inside the holder 110 (see- This is to allow unlocking of the outlet charger 100 and the inlet charger through a saw) movement.

To this end, the handle 130 forms an opening hole 132 to protrude the other side of the latch 106 to the outside.

In particular, the latch 106 is elastically supported to the handle 130 by the elastic member 108 while the other side is exposed to the outside of the handle 130. So, when the latch 106 is pressed on the other side, the elastic member 108 is compressed. And, when removing the external force, by the elastic restoring force of the elastic member 108, the latch 106 is returned to the initial state of the locked state of the outlet charger 100 and the inlet charger.

On the other hand, the module unit 160 is fixedly mounted inside the holder 110, and is provided with a locking latch 106, an electric device 102, a power terminal 104, and the like. Thus, as the module unit 160 in which the latch 106 for locking, the electric device 102 and the power terminal 1040 are integrated is assembled inside the outlet charger 100, the assembling property is significantly improved.

In particular, the holder 110 may be divided into a rear holder 112 and a front holder 114.

The rear holder 112 is directly inserted into the housing 120 to be detachably coupled to the housing 120 and forms a partition wall 113 to partition the inside in the axial direction.

At this time, the partition wall 113 is connected to the power line 10 of the module unit and forms a receiving member 115 to receive and support the power terminal 104 that supplies power to the inlet charger. In addition, the partition wall 113 passes through the first installation hole 117 to protrude to the outside by inserting one side of the latch 106 included in the module unit.

In addition, the front holder 114 is formed to block the front side of the rear holder 112 and finish, and expose the power terminal 104 supported by the receiving member 115 to the front side, and one side of the latch 106 The first installation hole portion 117 and the second installation hole portion 119 disposed in a straight line are formed to protrude outward.
