[0002] Electric vehicles are a type of transportation that uses electricity as its primary power source. Unlike traditional gasoline vehicles that rely on gasoline or diesel combustion for power, electric vehicles store electrical energy through onboard batteries and then use an electric motor to convert that electrical energy into mechanical energy, thereby propelling the vehicle forward. This power mode gives electric vehicles many unique characteristics. During the use of electric vehicles, they need to be charged at fixed locations. To ensure the convenience, safety, and efficiency of charging, a charging interface connector is required.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Reference Figures 1-3This utility model provides an embodiment of a novel charging interface connector, comprising a connector 1. A protective sleeve 2 is slidably connected to the outer wall of the connector 1. The protective sleeve 2 mainly shields the left and right ends of the connector 1 from the connection points with the charging head 7 and the delivery head 8, preventing rainwater from splashing onto the connection points of the connector 1 and causing damage. A guide tube 5 is fixedly connected to the inner wall of the protective sleeve 2. The guide tube 5 allows the locking block 4 to slide within the protective sleeve 2 without deviation in its movement trajectory, and ensures that the return spring 3 does not undergo significant deformation. A limit mechanism is provided on the inner wall of the protective sleeve 2. A slot 6 is provided on the outer wall of the connector 1, which has a horizontal opening and a vertical opening. When the locking block 4 coincides with the horizontal opening, it can carry the protective sleeve. 2. When the locking block 4 coincides with the vertical opening, the locking block 4 cannot move with the protective sleeve 2. The left end of the connector 1 is connected to the charging head 7, which is the plug part of the existing fixed gun line. The right end of the connector 1 is connected to the conveying head 8. The conveying head 8 is mainly connected to the connector 1 and can transmit electrical energy to the extension gun head to charge the vehicle through the conveying line 9. The right end of the conveying head 8 is provided with the conveying line 9. The side wall of the connector 1 is provided with the connecting component. The limiting mechanism includes the locking block 4. The locking block 4 passes through and slides on the inner wall of the protective sleeve 2. The protective sleeve 2 has a corresponding slot for the locking block 4, which can satisfy the sliding of the locking block 4 on the inner wall of the protective sleeve 2. The bottom end of the locking block 4 is elastically connected to the protective sleeve 2 through the return spring 3.
[0033] Reference Figure 1 , Figure 4 and Figure 5 The connecting assembly includes a tube 10, which is fixedly connected to the side wall of the connector 1. A pressing plate 12 is elastically connected to the inner wall of the front end of the tube 10 via a positioning spring 11. The left end of the pressing plate 12 is protruding, allowing the pressing plate 12 and wedge 13 to move along the inner wall of the tube 10 by pressing the protrusion. A wedge 13 is fixedly connected to the right end of the pressing plate 12. The wedge 13 is inclined, and when the inclined surface is compressed, it slides along the inner wall of the tube 10. The tube 10 is inserted into the inner walls of the delivery head 8 and the charging head 7, respectively. The delivery head 8 and the charging head 7 have corresponding slots for the tube 10, allowing for initial positioning and insertion. The wedge 13 is inserted into the inner walls of the delivery head 8 and the charging head 7, respectively. Figure 5As shown, the slot of the insertion tube 10 on the delivery head 8 has a slot corresponding to the wedge 13, which allows the wedge 13 to be inserted and limit the delivery head 8 in one direction. The inner wall of the front end of the insertion tube 10 is fixedly connected to one end of the positioning spring 11. When the pressing plate 12 moves forward, it will compress the positioning spring 11. When resetting, the reverse elastic force of the positioning spring 11 will bring the pressing plate 12 back to its original position. The other end of the positioning spring 11 is fixedly connected to the outer wall of the pressing plate 12. The pressing plate 12 is slidably connected to the inner wall of the insertion tube 10. The insertion tube 10 has slots corresponding to the pressing plate 12 and the wedge 13, which can satisfy their movement inside the insertion tube 10. The wedge 13 is slidably connected to the inner wall of the insertion tube 10. The pressing plate 12 is slidably connected to the inner wall of the connector 1. The connector 1 contains electronic components for transmission, which allows the connector 1 to function as a transferor of electrical energy.
[0034] Reference Figures 1-3 The bottom end of the locking block 4 is fixedly connected to one end of the return spring 3. When the locking block 4 moves downward, it will compress the return spring 3. When resetting, the elastic force of the return spring 3 will carry the locking block 4 to reset. The other end of the return spring 3 is fixedly connected to the inner wall of the top of the protective sleeve 2. The locking block 4 is locked on the inner wall of the slot 6. The locking block 4 is slidably connected to the outer wall of the guide tube 5.
[0035] Working principle: First, when connecting the fixed charging cable to the extension cable, insert the right end of connector 1 into the delivery head 8, and insert the tube 10 into the inner wall groove of the delivery head 8. Then, press the wedge 13 into the inner wall of the tube 10 and compress the positioning spring 11. When the wedge 13 and the inner wall groove of the delivery head 8 coincide, the reverse elastic force of the positioning spring 11 will reset the pressing plate 12 and the wedge 13, allowing the wedge 13 to be inserted into the inner wall groove of the delivery head 8 to complete the connection between connector 1 and delivery head 8. In the same way, connector 1 and charging head 7 can be connected to achieve long-distance charging.
[0036] When it is necessary to cover the connection between connector 1, charging head 7 and conveying head 8 in rainy weather, simply move the locking block 4 downward and compress the return spring 3 to separate the locking block 4 from the vertical opening of the slot 6, allowing the locking block 4 to enter the horizontal slot of the slot 6. Then move the locking block 4 to the right, taking the protective sleeve 2 with it, so that the protective sleeve 2 covers the connection between connector 1 and conveying head 8. When it is necessary to limit the movement, simply release the locking block 4 and use the reverse elastic force of the return spring 3 to push the locking block 4 upward to reset it, allowing the locking block 4 to lock into the vertical opening of the slot 6 to complete the limit movement.
[0037] When it is necessary to disconnect the connector 1 and the conveyor head 8, simply follow the second step to release the limit on the protective sleeve 2, allowing the protective sleeve 2 to move to... Figure 2In the initial position, simply press the pressing plate 12 and compress the positioning spring 11 to allow the pressing plate 12 to retract into the insertion tube 10 along with the wedge block 13. Then, separate the connector 1 and the delivery head 8 to remove the insertion tube 10 from the inner wall of the delivery head 8 and complete the disassembly.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
