[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0019] All features disclosed in this specification, or steps in all methods or processes disclosed herein, may be combined in any way, except for mutually exclusive features and / or steps.
[0020] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model discloses a protective device for an electric vehicle charging socket, including a charging socket 1. A sealing plug 2 is provided in the charging port of the charging socket 1. A plurality of positioning grooves 11 are provided on one end face of the sealing plug 2. The pins inside the charging socket 1 are all inserted into the positioning grooves 11. A sliding groove 5 is provided on the inner wall of the charging port. A slider 8 is slidably arranged inside the sliding groove 5. A plurality of spring pieces 9 are installed between the slider 8 and the sealing plug 2. The sealing plug 2 protrudes on one side facing the sliding groove 5 to form a sealing part 4. The sealing part 4 is inserted into the opening on the outside of the sliding groove 5.
[0022] In this embodiment, multiple magnets 10 are embedded in one end face of the sealing plug 2 with positioning groove 11. Metal blocks 7 are embedded in the inner wall of the charging port opposite the magnets 10. The magnets 10 are magnetically fixed to the corresponding metal blocks 7. The other end of the sealing plug 2 extends to the outside and is equipped with a handle 3. The metal blocks and magnets can magnetically position the inserted sealing plug, increasing the stability after insertion.
[0023] In this embodiment, limiting grooves 6 are provided on both sides of the slide groove 5. The end of the limiting groove 6 facing the opening of the charging socket 1 is not open. The two sides of the slider 8 protrude to form limiting parts 12. The limiting parts 12 are slidably disposed in the limiting grooves 6. The limiting parts and the limiting grooves can limit the slider, preventing the slider from falling out of the slide groove, so that the sealing plug can be connected with the charging socket, and preventing independent detachment.
[0024] In the embodiment, the sealing plug 2 is made of high-temperature-resistant insulating plastic material, and a fluororubber layer is arranged on the outer side of the sealing plug 2, which is in contact with the inner wall of the charging socket and seals the charging socket, thereby increasing the sealing between the sealing plug and the charging socket and better blocking heat through the fluororubber layer.
[0025] In the embodiment, the elastic sheet 9 is made of spring steel, which has high elasticity and fatigue resistance, and can be greatly deformed when subjected to external force and quickly return to the original shape after the external force is removed.
[0026] In the embodiment, one end of the sliding groove 5 extends to the inside of the charging socket 1, and the sliding block 8 is arranged at the deepest part of the sliding groove 5.
[0027] When not in use, the charging socket inside the charging socket is completely sealed by the sealing plug, and the sealing plug has a large thickness, which reduces the probability of being burned through, and because the sealing plug is wrapped with a fluororubber layer, the fluororubber has strong heat resistance, and also has excellent chemical corrosion resistance and aging resistance, which can effectively block the flame or high-temperature gas from entering the inside of the socket, and avoid further burning or explosion of the internal circuit.
[0028] When charging is needed, the sealing plug is pulled outwards by the handle, and after the sealing plug is separated from the metal block, the sealing plug can move outward along the sliding groove, and the movement of the sealing plug drives the elastic sheet and the sliding block, so that the sliding block moves stably along the limiting groove, and after the limiting part is in contact with one end of the limiting groove, it indicates that the sealing plug has been completely moved out of the charging socket. At this time, the sealing plug can be pressed downward around the elastic sheet, so that the sealing plug is vertically arranged below the opening of the charging socket, and after the charging plug is inserted into the charging socket, the sealing plug can be released, and the elastic sheet can make the sealing plug abut against the outer surface of the charging plug, so as to press the charging plug and the charging socket tightly and increase the stability of charging.
[0029] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any change or replacement without creative labor should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
