[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figure 1-5 The utility model provides a plug-in connector for connecting a charging pile to a power quality detector, including a charging gun 1 of the charging pile and a terminal socket 21 of the power quality detector 2, a protective cover 3 and an opening and closing assembly. The protective cover 3 is movably arranged on the power quality detector 2 and is located next to the terminal socket 21. The protective cover 3 has a shielding position for closing the terminal socket 21 in the movable stroke relative to the power quality detector 2; the opening and closing assembly is configured to drive the protective cover 3 out of the shielding position when the charging gun 1 is inserted into the terminal socket 21. Specifically, the protective cover 3 It is rotatably connected to the power quality detector 2, and the opening and closing assembly includes a rotating rod 4, a holster 11 and a first guide rod 22. The rotating rod 4 is fixedly connected to the protective cover 3, and a slide groove 41 is provided on the rotating rod 4. The slide groove 41 includes a connected spiral groove 411 and a straight groove 412; the holster 11 is fixedly connected to the charging gun 1, and a through hole 111 is provided on the holster 11. A ball rolling with the slide groove 41 is arranged at the through hole 111 of the holster 11; the first guide rod 22 is fixedly connected to the power quality detector 2, and the first guide rod 22 is slidably connected to the holster 11.

[0023] Before inserting the charging gun 1 into the terminal socket 21, the worker first needs to align the holster 11 on the charging gun 1 with the first guide rod 22 and the rotating rod 4, so that the rotating rod 4 enters the through hole 111 of the holster 11, and the first guide rod 22 enters the other hole of the holster 11. Then the worker holds the charging gun 1 and slowly brings the charging gun 1 close to the terminal socket 21. During this process, the ball in the through hole 111 first rolls with the spiral groove 411 in the slide groove 41, so that the rotating rod 4 can rotate. During the rotation of the rotating rod 4, the protective cover 3 is driven to rotate relative to the power quality detector 2, so that the electric protective cover 3 is separated from the shielding position, and the wiring is completed. The socket 21 is exposed to the outside; then the ball enters the straight groove 412 from the spiral groove 411. On the one hand, the charging gun 1 can continue to be pushed forward until it is inserted into the terminal socket 21, and on the other hand, the protective cover 3 no longer rotates; when the worker completes the power quality inspection of the charging pile, the worker pulls the charging gun 1 out of the terminal socket 21 and disengages from the sliding first guide rod 22. During this process, the ball first cooperates with the straight groove 412 to enable the charging gun 1 to be smoothly pulled out of the terminal socket 21, and then the ball rolls with the spiral groove 411 to make the dry rod rotate, thereby resetting the protective cover 3 to the shielding position, thereby preventing the worker from forgetting to reset the protective cover 3.

[0024] Compared with the prior art, the utility model provides a plug connector for connecting a charging pile to a power quality detector 2. Before the charging gun 1 is inserted into the terminal socket 21 of the power quality detector 2, the worker holds the charging gun 1 and performs an aligning action and an inserting action. During the process of the worker inserting the charging gun 1 into the terminal socket 21, the protective cover 3 can be driven out of the shielding position by the opening and closing component. In addition, after the power quality detector 2 finishes the power quality detection work on the charging pile, the worker pulls out the charging gun 1 from the terminal socket of the power quality detector 2 and moves it a distance. During this process, the protective cover 3 can be driven again to reset to the shielding position by the opening and closing component. On the one hand, the device can simplify the preparation work of the worker before connecting the charging gun 1 with the terminal socket 21, and on the other hand, it can effectively prevent the worker from forgetting to close the protective cover 3.

[0025] In another embodiment provided by the utility model, the protective cover 3 is slidably connected to the power quality detector 2, and the opening and closing assembly includes a second guide rod 5, a sliding sleeve 51, a holster 11, an elastic member 6 and a locking member, the second guide rod 5 is fixedly connected to the power quality detector 2; the sliding sleeve 51 is slidably connected to the second guide rod 5, a connecting rod 511 is hinged on the sliding sleeve 51, and the other end of the connecting rod 511 is hinged to the protective cover 3; the holster 11 is fixedly connected to the charging gun 1, and a through groove 112 is provided thereon for slidingly matching with the second guide rod 5; the elastic member 6 drives the sliding sleeve 51 to slide along the axial direction of the second guide rod 5 during the process of restoring the deformation, specifically, the elastic member 6 includes a spring, one end of the spring is connected to the power quality detector 2, and the other end of the spring is connected to the sliding sleeve 51; the locking member is used to lock the charging gun 1 with the power quality detector 2, specifically, the locking member includes a bolt 7, the bolt 7 is screwed on the holster 11, and a screw hole 23 is provided on the power quality detector 2 for screwing with the bolt 7.

[0026] Before inserting the charging gun 1 into the terminal socket 21, the worker first makes the second guide rod 5 enter the through groove 112 of the charging gun 1, so that the holster 11 can slide and cooperate with the second guide rod 5. As the charging gun 1 continues to approach the terminal socket 21, the holster 11 will push the sliding sleeve 51 to make the sliding sleeve 51 move relative to the second guide rod 5. During the movement of the sliding sleeve 51 relative to the second guide rod 5, the connecting rod 511 on the sliding sleeve 51 will push the protective cover 3 to move relative to the power quality detector 2. As the sliding sleeve 51 moves closer to the power quality detector 2, the protective cover 3 also slides and moves until it leaves the shielding position, and during the movement of the sliding sleeve 51, the sliding sleeve 51 will squeeze the spring. When the protective cover 3 is separated from the shielding position, the charging gun 1 continues to move so that the charging gun 1 is inserted into the terminal socket 21, and then the charging gun 1 is fixed on the power quality detector 2 by the cooperation of the bolt 7 and the screw hole 23, so as to prevent the charging gun 1 from falling off the terminal socket 21; when the power quality detection of the charging pile is completed, the bolt 7 is first turned to disengage the screw hole 23, and then the charging gun 1 is pulled out of the terminal socket 21 and separated from the second guide rod 5, and the elastic force of the spring drives the sliding sleeve 51 to slide relative to the second guide rod 5 and away from the power quality detector 2, and the sliding sleeve 51 will pull the protective cover 3 through the connecting rod 511 during the movement, so that the protective cover 3 can be reset to the shielding position.

[0027] There are two second guide rods 5 , which are located at two sides of the protective cover 3 , so that the charging gun 1 can be more stable during the movement.

[0028] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
