[0032] The present invention will be further described in conjunction with the following embodiments.

[0033] Depend on Figures 1 to 9 As can be seen, the new energy vehicle charging terminal connector described in this embodiment includes a housing 1 and a connecting arm 11 disposed on the housing 1; the end of the connecting arm 11 is provided with a connector head 2; the connector head 2 is provided with a connecting terminal 21.

[0034] A waterproof cover 3 is movably fitted over the connecting arm 11; the end of the waterproof cover 3 near the housing 1 is slidably sealed on the connecting arm 11; a waterproof cavity 31 is provided inside the waterproof cover 3; an opening 32 communicating with the waterproof cavity 31 is provided at the end of the waterproof cover 3 away from the housing 1; a left cover plate 41 and a right cover plate 42 are movably provided at the end of the waterproof cover 3 away from the housing 1.

[0035] The left cover plate 41 and the right cover plate 42 abut against each other to close the opening 32, thereby sealing the connector 2 inside the waterproof cavity 31.

[0036] The new energy vehicle charging terminal connector also includes a drive mechanism for driving the waterproof cover 3 to slide on the connecting arm 11.

[0037] Specifically, in this embodiment, before the new energy vehicle charging connector is plugged into the vehicle, the left cover plate 41 and the right cover plate 42 abut against each other to close the opening 32. At this time, the waterproof cavity 31 is in a sealed space, and the connector 2 is sealed in the waterproof cavity 31. This can prevent the connector 2 from being exposed to rain and high humidity, prevent short circuits and corrosion, and ensure the stability and service life of the charging equipment.

[0038] When it is necessary to connect with a car, the waterproof cover 3 is driven by the drive mechanism to slide towards the housing 1. When the waterproof cover 3 and the connector 2 move relative to each other, the end of the connector 2 pushes the left cover plate 41 and the right cover plate 42 to move to both sides, thereby opening the opening 32 and allowing the connector 2 to extend out of the waterproof cavity 31, thus facilitating connection with the car.

[0039] In this embodiment, a new energy vehicle charging connector is provided. The waterproof cover 3 has a left sliding groove 33 on one side of the opening 32; the waterproof cover 3 has a right sliding groove 34 on the other side of the opening 32; the left cover plate 41 has a left slider 43 that is slidably connected to the left sliding groove 33; the right cover plate 42 has a right slider 44 that is slidably connected to the right sliding groove 34; a support post 35 is provided at the middle of the end of the waterproof cover 3 away from the housing 1; a left tension spring 45 is provided between the left cover plate 41 and the support post 35; a right tension spring 46 is provided between the right cover plate 42 and the support post 35. In this embodiment, the left cover plate 41 has a left inclined surface 47 for abutting against the end of the connector 2; the right cover plate 42 has a right inclined surface 48 for abutting against the end of the connector 2; the end of the connector 2 pushes the left inclined surface 47 and the right inclined surface 48 to make the left cover plate 41 and the right cover plate 42 move away from each other.

[0040] Specifically, in this embodiment, before the new energy vehicle charging connector is plugged into the vehicle, the left cover plate 41 and the right cover plate 42 are brought close together and abutted against each other due to the tension of the left tension spring 45 and the right tension spring 46, thereby closing the opening 32. At this time, the waterproof cavity 31 is in a sealed space, sealing the connector 2 inside the waterproof cavity 31. This can prevent the connector 2 from being exposed to rain and high humidity, preventing short circuits and corrosion, and ensuring the stability and service life of the charging equipment.

[0041] When it is necessary to connect with a car, the drive mechanism drives the waterproof cover 3 to slide towards the housing 1, so that the end of the connector 2 abuts against the left inclined surface 47 and the right inclined surface 48. Under the action of the left inclined surface 47 and the right inclined surface 48, as the waterproof cover 3 slides towards the housing 1, the end of the connector 2 pushes the left cover plate 41 and the right cover plate 42 to move to both sides, thereby opening the opening 32, so that the connector 2 can extend out of the waterproof cavity 31, thus facilitating connection with the car.

[0042] The new energy vehicle charging terminal connector described in this embodiment includes a drive mechanism comprising a wrench 51 slidably disposed on a housing 1, a rack 53 disposed on the wrench 51, a gear 54 rotatably disposed on the housing 1, and a reel 55 coaxially driven with the gear 54; a traction rope 56 is wound on the reel 55; the traction rope 56 is connected to a waterproof cover 3; a connecting boss 22 is provided between the connector head 2 and the connecting arm 11; the drive mechanism also includes a return spring 23 disposed between the end of the waterproof cavity 31 away from the housing 1 and the connecting boss 22.

[0043] Specifically, when it is necessary to connect with the car, by pressing the wrench 51, the rack 53 is moved during the movement of the wrench 51, thereby causing the gear 54 and the reel 55 to rotate, and the traction rope 56 is wound onto the reel 55. Thus, the waterproof cover 3 can be slid towards the housing 1 by the traction rope 56.

[0044] This embodiment describes a new energy vehicle charging connector. The housing 1 is provided with a limiting groove 12; the wrench 51 is provided with a limiting block 52 that is slidably connected to the limiting groove 12; and a driving spring 57 is provided between the wrench 51 and the housing 1. Specifically, the above-mentioned arrangement enables the wrench 51 to move stably, and the driving spring 57 facilitates the wrench 51 to reset.

[0045] This embodiment describes a new energy vehicle charging connector, wherein the connecting boss 22 is provided with a drive rod 24; the waterproof cover 3 is provided with a guide groove 6; the drive rod 24 is slidably disposed in the guide groove 6; the end of the guide groove 6 away from the housing 1 is provided with a left receiving groove 61 and a right receiving groove 62; a left stop block 7 is provided telescopically within the left receiving groove 61; a right stop block 8 is provided telescopically within the right receiving groove 62; a left spring 73 is provided between the left stop block 7 and the left receiving groove 61; a right spring 83 is provided between the right stop block 8 and the right receiving groove 62; the left stop block 7 and the right stop block 8 protrude into the guide groove 6 from both sides and abut against each other. In this embodiment, a new energy vehicle charging connector is provided, wherein the left stop 7 and the right stop 8 are respectively provided with a first left inclined surface 71 and a first right inclined surface 81 for abutting against the front end of the drive rod 24; and the left stop 7 and the right stop 8 are respectively provided with a second left inclined surface 72 and a second right inclined surface 82 for abutting against the rear end of the drive rod 24. This embodiment of a new energy vehicle charging connector includes a waterproof cover 3 with a left locking groove 91 communicating with a left receiving groove 61 and a right locking groove 92 communicating with a right receiving groove 62. A left locking block 93 is telescopically movably disposed within the left receiving groove 61; a right locking block 94 is telescopically movably disposed within the right receiving groove 62. One end of the left locking block 93 and one end of the right locking block 94 protrude from the ends of the waterproof cover 3 away from the housing 1, respectively. The other end of the left locking block 93 protrudes into the left receiving groove 61; the other end of the right locking block 94 protrudes into the right receiving groove 62. A first tension spring 95 is provided between the left locking block 93 and the left receiving groove 61; a second tension spring 96 is provided between the right locking block 94 and the left receiving groove 61. In this embodiment of a new energy vehicle charging connector, the left stop 7 has a left boss 74 at the end away from the right stop 8 for abutting against the other end of the left locking block 93. In this embodiment, a new energy vehicle charging connector is provided with a right boss 84 at the end of the right stop block 8 away from the left stop block 7, which is used to abut against the other end of the right locking block 94.

[0046] like Figure 7 As shown, specifically, in this embodiment, before being connected to the car, the left cover plate 41 and the right cover plate 42 are brought closer together and abutted against each other due to the tension of the left tension spring 45 and the right tension spring 46, thereby closing the opening 32. At this time, the waterproof cavity 31 is in a sealed space, sealing the connector 2 inside the waterproof cavity 31. At the same time, under the action of the return spring 23, the drive rod 24 is located at the end of the guide groove 6 near the housing 1. Under the action of the left spring 73 and the right spring 83, the left stop block 7 and the right stop block 8 abut against each other. Under the action of the first tension spring 95 and the second tension spring 96, the other end of the left locking block 93 is offset from the position of the left boss 74, and the other end of the right locking block 94 is offset from the position of the right boss 84.

[0047] like Figure 8 As shown, when it is necessary to connect with the car, by pressing the wrench 51, the rack 53 is moved during the movement of the wrench 51, thereby causing the gear 54 and the reel 55 to rotate, and the traction rope 56 is wound onto the reel 55. That is, the waterproof cover 3 can be slid towards the housing 1 by the traction rope 56. During the sliding of the waterproof cover 3, the end of the connector 2 abuts against the left inclined surface 47 and the right inclined surface 48. Under the action of the left inclined surface 47 and the right inclined surface 48, as the waterproof cover 3 slides towards the housing 1, the end of the connector 2 pushes the left cover plate 41 and the right cover plate 42 to move to both sides against the tension of the left tension spring 45 and the right tension spring 46, thereby opening the opening 32, so that the connector 2 can extend out of the waterproof cavity 31.

[0048] Additionally, as the waterproof cover 3 slides towards the housing 1, the drive rod 24 slides along the guide groove 6 away from the housing 1. When the drive rod 24 slides to the position of the left stop 7 and the right stop 8, under the action of the first left inclined surface 71 and the first right inclined surface 81, the left stop 7 and the right stop 8 retract into the left receiving groove 61 and the right receiving groove 62. After the drive rod 24 passes the left stop 7 and the right stop 8, under the action of the left spring 73 and the right spring 83, the left stop 7 and the right stop 8 abut together again. Furthermore, after being connected to the car, the car pushes the left locking block 93 and the right locking block 94 to move inward, so that the other end of the left locking block 93 abuts against the left boss 74 and the other end of the right locking block 94 abuts against the right boss 84, so that the left stop 7 and the right stop 8 always abut together, which can prevent the drive rod 24 from resetting due to the action of the return spring 23.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
