Like numbers refer to like elements throughout.

1 illustrates an embodiment of a connector 100 of an electric vehicle charging device according to the present invention and a separated state of an inlet 200 of an electric vehicle in which the connector 100 is detachably mounted.

The inlet 200 may include a female power terminal 220 and a communication terminal 230 in the inlet housing 210 and may be shielded by an openable and openable cover 240.

Connector 100 of the electric vehicle charging device according to the present invention is provided with a terminal housing 130 inside the first body 110, the male power terminal 132 and the communication terminal (respectively) inside the terminal housing 130 ( 130 may be provided.

Therefore, when charging the electric vehicle, when the user mounts the connector 100 of the electric vehicle charging device to the inlet 200 and the connection between the terminals is completed, the electric vehicle charging device is a battery (not shown) of the electric vehicle via the connector. To charge the battery.

The terminal housing 130 equipped with the power terminal 132 and the communication terminal 130 of the connector 100 should be inserted into and mounted inside the inlet housing 210 constituting the inlet 200 in a charged state. In the charged state, it may not be exposed to the outside for safety or standard reasons.

That is, the terminal housing 130 on which the power terminal and the communication terminal 133 of the connector 100 are mounted may be exposed to the outside or displaced to the opening side only in a mounting state for charging.

Therefore, for such a selective exposure, protruding or displaced structure, the connector 100 has a first body 110 and the terminal housing 130 is mounted in the first body 110 to be slidably displaceable. It may have a structure.

In addition, the terminal housing 130 in which the power terminal 132 and the communication terminal 130 of the connector 100 are mounted is in a charged state, that is, the process of being mounted in the inlet housing 210 requires a predetermined magnitude or more of force. In addition, the lever 150 may be used to reduce the actual force of the user required during the mounting process. That is, by using the lever 150 to secure the gain of the force, the actual user can be easily mounted to the inlet 200 with the connector 100 with a small force. In particular, the elderly or female driver, if you do not use the lever can feel a physical burden during the mounting process of the connector.

In addition, the second body 140 may have a bent shape so that the user can easily hold the coupler 100 with one hand. A cable C connected to the plurality of terminals described above may pass through the second body 140.

Referring to Figure 2 below, the structure of the coupler of the electric vehicle charging apparatus according to the present invention will be described in detail.

2 shows a lateral perspective view of one embodiment of an electric vehicle charger connector according to the invention, and FIG. 3 shows a lateral perspective view of another embodiment of an electric vehicle charger connector according to the invention.

First, the connector of the electric vehicle charging apparatus according to the present invention will be described with reference to FIG. 2.

The connector of the electric vehicle charging apparatus according to the present invention includes a communication terminal (not shown) and a power terminal (not shown), the communication terminal and the terminal housing 130 mounted with the power terminal, and openings at both ends, and the terminal housing The first body 110, which is mounted so as to be displaceable in the internal space, is coupled to the first body 110 by a hinge, and the front end of the terminal housing 130 in the opening direction of any one of the openings. A lever 150 for propelling the terminal housing so as to be displaced, and a rear end of the terminal housing 130, which is pulled by the terminal housing 130 when the lever 150 rotates, and the first body A second body 140 that is slidable from the other opening of the 110 and is formed with a step that is limited to the insertion depth to the first body.

As shown in FIG. 2, a terminal housing 130 on which each terminal is mounted is disposed in front of the inner space of the first body 110, and a second body 140 is located after the terminal housing 130. Is connected to the end 130b.

The second body 140 is fastened to the rear end of the terminal housing 130, is pulled by the terminal housing 130 when the lever is rotated, the other opening of the first body 110 It is slidable at (113, see FIG. 4).

Specifically, the second body 140 has a diameter at the handle portion 141 and the enlarged portion 143 extending downward based on the enlarged portion 143 of the central region, so that the rear end portion of the terminal housing ( 130b) and may be partitioned into a sliding part 142 which is slidable at the other opening 113 (see FIG. 4) of the first body.

As shown in FIG. 2, the second body 140 has an enlarged portion 143 having the largest diameter, a handle portion 140 extending downward from the rear end of the enlarged portion 143, and a front end of the second body. A sliding portion 142 which is slidably inserted into the first body 110 and is slidably inserted into the first body of the sliding portion 142 while being fastened to the rear end of the terminal housing 130. It includes a step (S) formed at the boundary of the sliding portion and the enlarged portion to limit the depth.

In FIG. 2, although the step S is illustrated to limit the insertion depth of the sliding part 142 of the second body 140, the step S is understood as a means for limiting the insertion depth. This may be any structure as long as the structure restricts the insertion depth of the sliding part 142 such as a locking step, a protrusion or a partition wall on the surface of the sliding part 142.

That is, a structure for limiting the insertion depth may be formed on the surface of the sliding part without increasing the diameter of the sliding part 142 to replace the enlarged part 143.

Therefore, the diameter of the enlarged portion 143 may be larger than the diameter of the sliding portion 142 and the diameter of the handle portion.

Therefore, when the terminal housing 130 and the second body 140 are fastened in the first body 110 and the terminal housing 130 is displaced in the first body 110, the The sliding part 142 of the second body 140 may also be displaced in the first body 110.

The second body 140 is reduced in diameter at the handle portion 141 and the enlarged portion 143 which extends downward based on the enlarged portion 143 of the central area, and thus at the rear end 130b of the terminal housing. When fixed and fastened and partitioned by the sliding part 142 which is slidable from the other opening 113 of the first body 113 (see FIG. 4), there are advantages as follows.

The insertion depth of the second body 140 slidingly inserted into the first body 110 constituting the body of the connector is caused by a step between the enlarged portion 143 and the sliding portion 142 of the second body 140. Since it is limited, it is possible to prevent damage to the coupler even in the pulling operation of the user's excessive lever.

In addition, when the lever is repeatedly used for a long time, the first body 110 may be subjected to a stress such as repeated twisting by the second body, the first body consisting of two covers (see FIG. 4). ) Weakens the bonding state. Such a structure may eventually cause play and weaken the waterproofing performance, but the insertion depth of the second body to the first body may be limited by the step between the enlarged part 143 and the sliding part 142. If so, durability and waterproofing can be prevented.

The terminal housing 130 may be pushed in a predetermined direction, for example, a left direction (see FIG. 2) of the horizontal direction by the lever 150 to be described later. The reason for pushing the terminal housing 130 is to displace the terminal housing 130 forward in the process of mounting the connector 100 according to the present invention to the inlet 200. That is, the terminal housing 130 acts as a propulsion member that is pushed by the lever.

Since the connector of the electric vehicle charging device according to the present invention has a structure in which the housing in which the terminal is accommodated by the lever is directly propelled, the number of driving parts can be minimized because a separate propulsion member is not used.

The second body 140 is fastened to the rear end 130b of the terminal housing 130, may be towed by the terminal housing 130, and another opening of the first body 110. It may be slidable at 113 (see FIG. 4).

Specifically, the second body 140 is extended and bent from the handle portion 141 and the handle portion 141 is fastened to the rear end portion (120a) of the terminal housing 130 of the first body 110 It may include a sliding portion 142 slidable to the other opening.

As shown in FIG. 2, the sliding part 142 of the second body 140 is fastened and fixed to the rear end 130b of the terminal housing 130 within the rear end area of the first body 110. The handle part 141 integrally formed with the sliding part 142 may be configured in a pipe shape through which the cables C connected to the plurality of terminals 131 pass.

Specifically, as shown in FIG. 2, the sliding part 142 of the second body 140 is fixed to the rear end 130b of the terminal housing 130 to slide on the rear half of the first body 110. It is installed to be possible, and provided with an inner path through which the cable (C) passes, and has a handle portion 141 in the form of a handle that can be grasped by a user's hand, and the size corresponding to the inner diameter of the inner path in the second half. It may be configured to have a cable protection member 145 having a fitting.

The handle part 141 and the sliding part 142 may be bent at an angle that is easy for the user to hold by hand.

The sliding part 142 of the second body 140 is a portion parallel to the longitudinal direction of the first body 110 or the displacement direction of the terminal housing. Rather than the handle portion and the sliding portion is not clearly distinguished and formed in a gentle curve or the like, the horizontal sliding portion and the handle portion bent at the end of the configuration configured by the method, such as when pulling the lever 150 Smooth sliding operation is possible, and durability can also be improved.

The cable protection member 145 is made of a rubber material to protect the cable (C) introduced to the connector 100. In addition, since the size of the cable protection member 145 is formed in a size corresponding to the inner diameter of the second body 140, it is possible to apply and use a cable of various sizes to the connector 100, to ensure the airtight immersion Safety accidents such as back can be prevented.

The terminal housing 130 requires propulsion force converting means for converting the rotation moment of the lever 150 into a propulsion force in a predetermined direction in order to be propelled by the lever 150 when the lever 150 rotates.

Therefore, the connector of the electric vehicle charging device according to the present invention is to propel the terminal housing according to the rotational trajectory of the guide pin according to the rotation of the lever at the upper end of the guide pin and the upper side of the terminal housing as a driving force conversion means.

The guide pin 136 is inserted into the guide hole 1502 of the upper end 159 of the 150 to propel the terminal housing 130.

The guide pin 136 converts the rotational force of the lever into the horizontal driving force in accordance with the rotational trajectory of the guide hole 152. Therefore, the guide hole 152 may be configured in the form of a long hole.

The guide hole 1502 may be formed to be parallel to the longitudinal direction of the upper end 159 of the lever 150.

The guide pins 136 may be provided in pairs at positions corresponding to each other on both side surfaces of the terminal housing. In addition, the upper end 159 of the lever 150 may be branched near the hinge 151 to be bent and extended in the direction of each guide pin.

Since the object to be propelled by the lever 150 is a guide pin 136 provided in the terminal housing 130, the rotation moment applied when the lever is rotated by increasing the distance between the guide pin 136 and the hinge of the lever. By maximizing, there is an advantage that the size of the user's force required in the mounting process of the connector can be minimized.

As described above, the lever 150 may be hinged to the first body 110 by a hinge 151. The hinge 151 may be provided with a spring 158 (see FIG. 4) to provide a restoring force when the lever 150 rotates.

Therefore, when the user grasps the handle 141, which is the lower region of the second body 140, and pulls the lever 150 toward the second body 140, the guide pin 136 is the guide hole 152. Pressed along the inner wall surface, it is propelled in the horizontal direction can displace the terminal housing 130 to one side.

By such a structure, the terminal housing 130 and the second body 140 may be slide-displaced together as the terminal housing 130 is displaced in a fastened and fixed state.

The guide pins and the guide holes are interchanged with each other so that guide pins are provided at the upper end of the lever, and guide holes for inserting the guide pins of the levers are provided at the side surfaces of the terminal housing 130. You may.

The propulsion structure of the terminal housing 130 described above is for mounting the connector to the inlet of the electric vehicle to charge the electric vehicle, and after the mounting process of the connector is completed, the state is maintained in the mounting state A structure for maintaining the mounting state in order to perform the charging process will be described with reference to FIGS. 2 and 3.

The connector 100 of the electric vehicle charging device according to the present invention is the terminal housing 130 or the second body 140 propelled to fix the state in which the terminal housing 130 is displaced from the first body 110. It may further include a fixing latch that is fixed to the locking. That is, the fixed latch serves to restrain the displaced terminal housing or the second body to remain in the displaced state.

Specifically, in the embodiment shown in Figure 2, the fixed latch 161 is fixed to the displacement state of the displaced second body 140, in the embodiment shown in Figure 3, the fixed latch 161 is displacement The terminal housing 130 is fixed.

Thus, in the embodiment shown in Figures 2 and 3, each of the fixing latch 161 is fixed to the terminal housing 130 or the second body 140 in accordance with the position of the locking projection to be fixed to the fixed latch. .

In the embodiment shown in Figure 2, the locking projection 1402 is provided on the upper surface of the second body 140, the embodiment shown in Figure 3 the locking projection 1302 is the terminal housing 130 The rear end of the 130b is provided on the top surface.

Each of the locking protrusions 1302 and 1402 maintains the displaced state of the second body 140 or the lever 150 while the terminal housing 130 is propelled according to the rotation of the lever 150. It is provided to fix it.

Each of the locking protrusions 1302 and 1402 may have different cross-sectional inclinations. The reason why the inclination is different will be described later.

In addition, the embodiment illustrated in FIG. 3 may further include a fastening latch 111 for maintaining a state in which a connector is fastened to an inlet of an electric vehicle, unlike the embodiment illustrated in FIG. 2.

In the embodiment shown in Figure 2 or 3, the fixing latch 161 is configured to fix the state in which the terminal housing is pushed by the lever. That is, it is a configuration for maintaining the protruding or displaced state of the terminal housing during the charging process of the electric vehicle.

In addition, in the state shown in FIG. 3, the fastening latch 111 is configured to block the first body 130 from being unintentionally separated from the state mounted to the inlet 200.

That is, the fastening latch 111 is configured to block the connector from being separated from the inlet of the electric vehicle in a situation where the terminal housing is pushed by the fixed latch.

As shown in FIG. 3, the fixed latch 161 and the fastening latch 111 may be hinged to the inner top surface center of the connector housing, respectively.

The fixed latch 161 is configured such that one end 161a is selectively pressed by a release button 162 to be described later, and the other end 161b of the fixed latch 161 is a locking protrusion 1302 of the terminal housing to be described later. Fixing protrusions (161c) that are caught on may be provided.

One end 111a of the fastening latch is disposed above the other end of the other end 161b of the fixed latch, and a fastening protrusion 111c is formed at the other end 111b of the fastening latch, and the fastening protrusion 111c of the connector housing. It may protrude to the outside.

The reason why the one end 111a of the fastening latch 111 is disposed above the other end of the other end 161b of the fixed latch is to release the fastening state at the same time. That is, the other end 161b of the fixed latch presses and rotates the lower end of the one end 111a of the fastening latch in the process of releasing the fixed latch, thereby lowering the other end of the fastening latch on which the fastening protrusion 111c is formed, thereby causing the fastening protrusion. The fastening state to the electric vehicle inlet can be released.

As described above, the terminal housing 130 and the second body 140 may be provided with locking projections 1302 and 1402 to be selectively locked by the fixing protrusion 161c.

The locking protrusions 1302 and 1402 may be at least one protrusion formed on an upper end surface of the terminal housing and an upper end surface of the sliding part of the second body. Side slopes of the cross section of any one of the protrusions may be different. This is to enable the locking operation for the fixed latch.

A plurality of the locking protrusions are provided, and a method of forming a seating space therebetween is also possible, but only one case will be described for convenience of description.

One side surface of the locking protrusions 1302 and 1402 (the right side of 1302 and 1402 of FIGS. 2 and 3) and one side surface of the locking protrusion 161c (the left side of 161c of FIGS. 2 and 3). Each may have a vertical slope.

This is to prevent the fixing state from being easily released by the fixing latch. That is, when the fixing protrusion 161c passes over the locking protrusion 122, when the terminal housing 130 is retracted by a restoring force such as a spring mounted on the lever 150, the locking protrusion and The vertical inclined surfaces of the fixing protrusions may be supported by each other to prevent retraction of the terminal housing.

The other side surfaces of the locking protrusions 1302 and 1402 (left side of 1302 and 1402 of FIGS. 2 and 3) and one side surface of the fixing protrusion (right side of 161c of reference numerals of FIGS. 2 and 3) are inserted into a connector. In order to minimize physical resistance in the process may have a gentle slope in the direction corresponding to each other. The fixed latch or the fastening latch is coupled to the connector housing by a hinge, and elasticity may be added by an elastic member such as a spring, so that the fixing protrusion and the locking protrusion having the corresponding gentle inclined surface have separate resistances during the mounting process of the connector. Since it can be carried over without mounting, when the connector 100 is mounted on the inlet 200, the connector 100 may 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 inclinations on both sides with respect to the cross section. Thus, that is, the inclination of the left side is gentle, the inclination of the right side is formed to be steeply close to the vertical, and when mounted on the inlet 200 can be installed with a minimum of physical resistance with a smooth, The right side is fixed to the back (not shown) to prevent the state mounted on the inlet can be easily released.

In the embodiment shown in Fig. 3, when the connector 100 is mounted and the charging is completed, there is a need for a removable structure for releasing the mounting state of the connector.

Therefore, the embodiment according to the present invention shown in FIG. 3 is for releasing the fixed state of the terminal housing 130 by the fixing latch 161 (or fixing protrusion 161 (c)) to the first body. It includes a release button 162, when the one end (161a) of the fixed latch is pressed by the release button 162 and the fixed projection (161c) provided at the other end (161b) of the fixed latch at the same time the body As the one end 111a of the tooth is raised, the other end 111b of the fastening latch is lowered, and the fastening protrusion 111c formed at the other end 111b releases the fastening state from the electric vehicle inlet. The release operation releases the fastening state of the fastening latch.

2 does not include a fastening latch that maintains a fastening state, but a method of releasing a fixed state by a fixed latch is the same as the embodiment shown in FIG.

The release button 162 is provided to press the release button so that the fixing protrusion 116c of the fixing latch 116 is caught by the locking protrusion 1402 provided on the upper surface of the sliding part 142 of the second body 140. You can selectively release the frozen state.
