Hereinafter, after the mounting process of the connector is completed, The structure for maintaining the mounting state for performing the charging process will be described with reference to FIGS. 2 and 3. FIG.

The connector 100 of the electric vehicle charging apparatus according to the present invention is characterized in that the connector body 110 is fixed to the terminal housing 130 or the handle 140 propelled to fix the displaced state of the terminal housing 130 in the connector body 110 As shown in FIG. That is, the fixed latch serves to restrain the displaced terminal housing or handle to remain displaced.

2, the fixed latch 161 fixes the displacement state of the displaced handle 140, and in the embodiment shown in FIG. 3, the fixed latch 161 is connected to the displaced terminal 140. In the embodiment shown in FIG. And the housing 130 is fixed.

Thus, in the embodiment shown in FIGS. 2 and 3, each of the fixed latches 161 fixes the terminal housing 130 or the handle 140 according to the position of the latching protrusion that is locked with the fixed latch.

In the embodiment shown in FIG. 2, the locking protrusion 1402 is provided on the upper surface of the handle 140, and in the embodiment shown in FIG. 3, the locking protrusion 1302 protrudes from the rear of the terminal housing 130 And is provided on the upper end surface of the end portion 130b.

Each of the locking protrusions 1302 and 1402 is fixed to the handle 140 or the lever 150 so as to maintain the displaced state of the handle 140 or the lever 150 in a state in which the terminal housing 130 is propelled in accordance with the rotation of the lever 150. [ .

Each of the engaging projections 1302 and 1402 may have different slopes in the cross direction. The reason why the slope is different will be described later.

In addition, the embodiment shown in FIG. 3 may further include a locking latch 111 for maintaining a state where the connector is fastened to the inlet of the electric vehicle, unlike the embodiment shown in FIG.

In the embodiment shown in FIG. 2 or 3, the fixed latch 161 is a structure for fixing the state in which the terminal housing is propelled by the lever. That is, it is a structure for maintaining the protruded or displaced state of the terminal housing in the charging process of the electric vehicle.

In the state shown in FIG. 3, the locking latch 111 is configured to prevent unintentional disconnection of the connector body 130 when the connector body 130 is mounted on the inlet 200.

That is, the locking latch 111 is configured to block the connector from being separated from the inlet of the electric vehicle in a state in which the terminal housing is propelled by the fixed latch.

As shown in FIG. 3, the fixing latch 161 and the locking latch 111 may be hinged to the center of the inner upper surface of the connector body, respectively.

One end 161a of the fixed latch 161 is selectively pressed by a release button 162 which will be described later and the other end 161b of the fixed latch 161 is connected to the latching protrusion 1302 of the terminal housing, And a fixing protrusion 161c which is engaged with the fixing protrusion 161c.

The fastening protrusion 111c is formed at the other end 111b of the fastening latch 111c and the fastening protrusion 111c is formed at the other end of the fastening protrusion 111c. And can be projected to the outside.

One end 111a of the locking latch 111 is disposed above the other end of the other end 161b of the fixed latch so that the locked state releasing operation can be released simultaneously.

Since the fixing latch or the latching lever is coupled to the connector body by a hinge and elasticity can be added by an elastic member such as a spring, the fixing protrusion and the latching protrusion having a corresponding gentle slope can be separated by a separate resistor Therefore, when the connector 100 is mounted on the inlet 200, the connector 100 can be smoothly mounted on the inlet without requiring a large force.

The fastening protrusions 111c formed on the fastening latch 111 of the embodiment shown in FIG. 3 may also have different slopes on both sides with respect to the cross section. In other words, the inclination of the left side surface is gentle and the inclination of the right side surface is formed so as to be steep close to the vertical, so that when mounted on the inlet 200, it can be smoothly mounted with minimal physical resistance, The right side surface is hooked and fixed so that the state of being mounted on the inlet can be prevented from being easily released.
