Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in detail, focusing on the parts necessary to understand the operation and action according to the present invention.

1 to 3, the charging plug for an electric vehicle according to the present invention includes an electric connector 100, a wire 200, a wire cover 300, a body 400, a lever 500, , An elastic member (not shown), and an elastic member guide 700 or the like. Hereinafter, for convenience of description, the direction in which the electric connector 100 protrudes from the body 400 toward the charging part of the electric vehicle is called a forward direction (arrow A), and the opposite side is called a reverse direction (arrow B).

The electrical connector 100 forms the appearance of the electrical connector 100 and is connected to the connector housing 110 which is installed on the body 400 so as to be forward and backward, and electrically connected to the inlet of the charging part of the electric vehicle. It may include a terminal (not shown) installed in the 110.

4 to 8, the wire 200 and the wire cover 300 will be described as follows.

The wire 200 may be formed of a plurality of strands for signal transmission, including electricity supply. The plurality of strands of wire 200 may be tied together to form a wiring harness structure. That is, the plurality of strands of wire 200 may be integrated into a wiring harness structure by being wired together in one sheath 210, but the front portion 202 connected to the electrical connector 100 is the electrical connector 100. The sheath 210 is peeled off for electrical connection. Hereinafter, when a plurality of strands of wire 200 are bundled and described, the wire 200 is referred to as a wiring harness 200.

The wire cover 300 may be made to protect the wiring harness 200 to prevent the wiring harness 200 from being damaged by friction with the body 400. In particular, the wire cover 300 is bound to one with the wiring harness 200 can be made to be integrally movable with the wiring harness 200 in accordance with the forward, backward of the electrical connector 100.

The wire cover 300 may include a clamping 310, a bracket 320, a crimping ring 330, a crimping panel 340, and the like.

The clamping 310 is used to bind the wire cover 300 to the wiring harness 200 in one piece, and is preferably formed in a ring shape to fit the wiring harness 200 to the outside of the wiring harness 200. It can be crimped.

It may be desirable for the clamping 310 to be coupled to the uncovered portion of the sheath 210 of the wiring harness 200 so that the wiring harness 200 can be more easily and firmly coupled to the wiring harness 200.

The bracket 320 is for protecting the wiring harness 200.

That is, the bracket 320 may be divided into a plurality of bracket members 320a and 320b along the circumferential direction of the wiring harness 200 to wrap the wiring harness 200 to which the clamping 310 is coupled. have. That is, as the bracket 320 is formed of a plurality of bracket members 320a and 320b, the wiring harness 200 may be easily inserted into or separated from the bracket 320 without being damaged. At this time, the bracket 320 may be formed corresponding to the size of the wiring harness 200 to increase the binding force with the wiring harness 200.

One side of the bracket 320 may be coupled to move integrally with the electrical connector (100). That is, the bracket 320 may be formed at the front end of the bracket front fastening hole 321 to be fixed to the connector housing 110 of the electrical connector 100 by the fastening of the fastening member 10, such as a screw. . In addition, the bracket 320 may be provided with a locking hole 322 into which the protrusion 111 protruding from the outer surface of the connector housing 110 of the electrical connector 100 is fitted, and thus the locking hole of the bracket 320. 322 may be fitted to the protrusion 111 of the electrical connector 100. Therefore, the bracket 320 is coupled to the electrical connector 100 and can be easily interlocked integrally without friction with the wiring harness 200 according to the forward and backward movement of the electrical connector 100.

The other side of the bracket 320 may be provided with a clamping position fixing portion for fixing the position where the clamping 310 is seated on the bracket 320 so as to be coupled to the wiring harness 200 through the clamping 310. The clamping position fixing part has a locking jaw 323 protruding from the bracket 320 so that the clamping 310 can be caught on the opposite side of the electrical connector 100 around the clamping 310 (hereinafter, 'locking jaw for fixing the clamping position'). It may include). That is, the clamping position fixing jaw 323 may be in close contact with the rear end of the clamping (310). Here, since the front end of the wiring harness 200 is connected to the electrical connector 100 and the front end of the bracket 320 is connected to the electrical connector 100, the clamping position fixing jaw 323 is clamped. Instead of fixing the 310 in both front and rear directions, it may be sufficient to fix the position only at the rear of the clamping 310.

A plurality of bracket members 320a and 320b may be hooked to each other, so that one of the bracket members 320a may have a hook 325 that can be fitted to a hook hole 324 formed in the adjacent bracket member 320b. Can be formed.

The bracket 320 corresponds to the length of the wiring harness 200 inserted into the body 400 so as to generally protect the wiring harness 200 inserted into the body 400. It may be formed long.

In particular, the bracket 320 may be formed to correspond to the structure of the body 400 so as not to cause structural interference with the body 400 while moving together with the electrical connector 100. That is, the bracket 320 is connected to the front part 326 positioned in parallel with the interior of the body cover 410 of the body 400 and the rear part of the front part 326 and corresponding to the grip of the body 300. The rear portion 327 may be formed to be inclined with respect to the portion 326 and positioned on the body grip 420 of the body 400. Thus, even if the bracket 320 is formed in a shape such as '∧' in the forward and backward directions (arrow A, arrow B) corresponding to the body 400, the body cover 410 and the body grip as will be described later Since 420 is coupled to move relative to the movement of the electrical connector 100, the electrical connector 100 can be moved without causing structural interference with the body 400 when moving forward or backward.

On the other hand, the front portion 326 of the bracket 320 is connected to the rear portion 327 of the bracket 320 and the wire of the plurality of strands of the front portion 202, the coating 210 of the wiring harness 200 is peeled off It may include a bracket connecting portion 326a formed to guide together integrally, and a plurality of branching portions 326b formed in front of the bracket connecting portion 326a to guide the branched wires 200. . Accordingly, the plurality of strands of wires may be branched by the plurality of branching portions 326b to be easily connected to the electrical connector 100.

The crimping ring 330 is formed in a ring shape by a material having excellent elasticity such as silicon, and is fitted to the outside of the bracket 320 so as to overlap the clamping 310 coupled to the wiring harness 200 by elastic force. The clamping 310 and the bracket 320 may be pressed onto the wiring harness 200. Accordingly, the binding force of the clamping 310 and the bracket 320 may be increased by the crimping ring 330, and the waterproofness and airtightness may be prevented so that moisture, foreign substances, etc. do not flow between the bracket 320 and the wiring harness 200. This can be further increased. The center hole 332 of the crimping ring 330 may be formed to correspond to the outer shape of the bracket 320 so that the crimping ring 330 is fitted to the outside of the bracket 320 to be in close contact. For example, the central hole 332 of the crimp ring 330 may be approximately circular. In addition, as shown in FIG. 2, the outer shape of the crimping ring 330 is in close contact with the inner surface of the second handle portion 424b of the body grip 420 as described above. The wire cover 300 may be formed to correspond to the internal shape of the second handle 424b of the body grip 420 so that the wire cover 300 may be press-fitted into the body grip 420. For example, the outer shape of the pressing ring 330 may be formed in a circular shape having a diameter approximately equal to the inner diameter of the second handle 424b of the body grip 420.

The pressing panel 340 is for fixing the wiring harness 200 to the bracket 320 so that the binding force between the wiring harness 200 and the bracket 320 can be increased. The bracket 320 and the wiring harness Interposed between the 200 may be provided with a pressing projection 342 protruding toward the wiring harness 200 to compress the wiring harness 200. In particular, when the bracket 320 is formed so that the coating 210 portion of the wiring harness 200 and the coating 210 of the wiring harness 200 can be uniformly bound regardless of the peeling front portion 202. Since the space between the bracket 320 and the front portion 202 where the sheath 210 of the wiring harness 200 is peeled off occurs relatively, the pressing panel 340 has a sheath 210 of the wiring harness 200. It may be preferable that the coating 210 of the wiring harness 200 is installed to correspond to the peeled front part 202 so as to compress the peeled front part 202. The pressing panel 340 may have a fastening hole 344 to which the fastening member 20 is fastened to be fastened to the bracket 320 by a fastening member 20 such as a bolt. The crimping protrusion 342 may be provided with one or more than two pieces, and preferably, a plurality of crimping protrusions 342 may be provided so that the coating 210 of the wiring harness 200 can be divided and crimped.

On the inner side of the first handle 424a, a binding protrusion 426 protruding from the wire cover 300 so as to be coupled to the wire cover 300 and interlocked with the wiring harness 200 is provided. Can be formed. Therefore, the wire cover 300 is press-fitted into the first handle 424a by the binding protrusion 426 to structurally bind the body grip 420 and the wire cover 300 to one through the wire cover 300. The body grip 420 may be interlocked with the wire 200. Accordingly, friction between the body grip 420 and the wire cover 300 is prevented, and the wiring harness 200 is connected between the coupling part 422 and the handle part 424 of the body grip 420. Even if the forward and backward directions (arrow A and arrow B) of the wiring harness 200 is prevented from being caught in the body grip 420, damage to the wire cover 300 can be prevented and the lever ( The operation of 500 can be made smooth and smooth.

Referring to FIG. 2, the second handle 424b may correspond to the wire cover 300, more precisely, the crimp ring 330 of the wire cover 300, so that the wire cover 300 may be press-fitted. The inner diameter of the wire cover 300 may be formed in a size that can be in close contact with the pressing ring 330. Accordingly, the body grip 420 and the wire cover 300 may be combined into one structurally. Here, since the body grip 420 is divided into a plurality of pieces 420a and 420b along the circumferential direction of the body grip 420 as described above, the wire cover 300 is easy to the body grip 420. Can be press-fitted.

The body coupling part 430 allows the body grip 420 and the body cover 410 to be integrally coupled, and in particular, the body grip 420 and the body cover 410 move forward and backward (arrow A, arrow B). It can be characterized in that the coupling so as to move relative to each other along.
