[0026] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. All other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.
[0027] According to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , a high-voltage connector plug and socket mating error insertion prevention structure includes a special-shaped boss 102, which is arranged at the insertion end of the connector socket 1, the direction of which is parallel to the axial direction of the connector socket 1, and the height of which is higher than the socket body flange 101 arranged at the insertion end of the connector socket 1. The main function of the special-shaped boss 102 is to achieve a limiting function, which can effectively reduce the shaking phenomenon when the connector plug 2 and the connector socket 1 are matched, and prevent the connector plug 2 from being inserted obliquely into the connector socket 1. Through this design, the situation that the mating sealing portion 203 is frequently turned over or pushed out due to the oblique insertion of the connector plug 2 during the matching process of the connector plug 2 and the connector socket 1 can be avoided, thereby ensuring the air tightness.
[0028] The guide insertion slot 202 is located at the insertion end of the connector plug 2, and is matched with the special-shaped boss 102. The insertion end of the connector plug 2 is provided with an insertion slot 201 for loading the mating sealing portion 203, and the insertion slot 201 is matched with the socket body flange 101.
[0029] According to Figure 7 , Figure 8 and Figure 9As shown, when the connector plug 2 mates with the connector socket 1, the irregular protrusion 102 gradually inserts into the guide slot 202. When the irregular protrusion 102 is inserted to a certain position in the guide slot 202, the socket body flange 101 begins to contact the mating sealing part 203. Subsequently, the socket body flange 101 gradually covers the mating sealing part 203 until the connector plug 2 and the connector socket 1 are fully inserted. The mating sealing part 203 plays a sealing role at the mating point of the connector plug 2 and the connector socket 1. This design not only ensures that the connector plug 2 and the connector socket 1 can fit perfectly, but also prevents interference between the anti-misalignment structures. During the process of pulling out the connector plug 2, this structure can effectively limit the tilt angle of the connector plug 2, thereby preventing the mating sealing part from being flipped or pushed out.
[0030] In this embodiment, when the irregular protrusion 102 is inserted to three-fifths of the position in the guide slot 202, the socket body flange 101 and the mating sealing part 203 begin to contact. This precise design effectively avoids the connector plug 2 from being inserted at an angle and plays a key limiting role in the entire insertion process.
[0031] In this embodiment, at least two irregular protrusions 102 are provided. This design can precisely limit the engagement of the connector plug 2 and the connector socket 1 from multiple positions and angles, thereby forming multiple positioning points or positioning areas.
[0032] In this embodiment, the cross-section of the irregular boss 102 adopts the shape of I, cross, straight, earth, dry, king, wedge, and trapezoid. Designing such a structure can not only enhance the accuracy of guidance and positioning, but also significantly improve the stability of the entire structure.
[0033] In this embodiment, the guide slot 202 is located in the middle of the insertion slot 201.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
