[0037] like Figures 1-7 As shown, this embodiment of the present invention provides a high-voltage connector assembly, including a housing 3, a first inner core 1, and a second inner core 2. The housing 3 has a slot 30 for inserting either the first inner core 1 or the second inner core 2. The first inner core 1 includes a first terminal 11 and a shield 12 disposed around the outer periphery of the first terminal 11. The first inner core 1 and the second inner core 2 have the same shape and size, allowing both the first inner core 1 and the second inner core 2 to be smoothly inserted into the slot 30 of the housing 3.
[0038] The high-voltage connector assembly provided in this embodiment allows for selective insertion of either the first inner core 1 or the second inner core 2 into the slot 30 within the housing 3. When the second inner core 2 is inserted into the slot 30, it is in an unshielded state. When the first inner core 1 is inserted into the slot 30, the high-voltage connector is shielded due to the shielding cover 12 surrounding the first terminal 11 of the first inner core 1. This invention innovatively introduces replaceable shielding cover technology. Since the first inner core 1 and the second inner core 2 have the same shape and size, they can be interchanged, allowing for flexible switching between different usage scenarios and greatly improving product adaptability. It perfectly meets requirements in both shielded and unshielded systems without requiring a complete replacement, thus significantly reducing costs. Furthermore, this invention achieves a perfect balance between compatibility and cost control while ensuring performance. It not only meets various complex usage requirements but also saves users significant financial investment. Simultaneously, it improves inventory management efficiency, ensuring stable operation in different system environments, guaranteeing both good compatibility and effective cost control. This invention opens up new avenues for the application of high-voltage connectors, bringing users higher cost-effectiveness and a wider range of choices.
[0039] like Figure 1 , Figure 4 As shown, in one embodiment of the present invention, the shielding cover 12 is a sheet metal semi-enclosed shell structure with a notch 121 corresponding to the first terminal 11.
[0040] like Figure 1 , Figure 3 , Figure 4 As shown, in order to improve the shielding effect, in one embodiment of this utility model, the shielding cover 12 is provided with a shielding ring 13 at its end for shielding the cable connected to the first terminal 11. Furthermore, the shielding ring 13 contacts the shielding cover 12 via a spring contact 131.
[0041] like Figure 1 As shown, in one embodiment of this utility model, there are two of the first inner core 1 and the second inner core 2, that is, the high-voltage connector is a 2-pin connector.
[0042] like Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 7As shown, in one embodiment of this utility model, the housing 3 is cylindrical, and a first opening 31 and a second opening 32 are respectively provided at both ends of the housing 3. The first opening 31 is used for the insertion of the first inner core 1 or the second inner core 2 into the housing 3, and the second opening 32 is used for the insertion of the plug of the board end mating with the high-voltage connector into the first terminal 11 or the second inner core 2. Furthermore, the opening directions of the first opening 31 and the second opening 32 are perpendicular to each other.
[0043] like Figure 1 , Figure 3 , Figure 4 , Figure 6 , Figure 7 As shown, in order to achieve a stable connection between the first inner core 1 or the second inner core 2 and the housing 3, in one embodiment of this utility model, the inner walls on both sides of the slot 30 are provided with positioning grooves 33, and the outer walls on both sides of the first inner core 1 and / or the second inner core 2 are provided with positioning protrusions 34 corresponding to the positioning grooves 33. Further, the longitudinal section of the positioning protrusion 34 is triangular.
[0044] like Figure 1 As shown, in order to reduce friction when the first inner core 1 or the second inner core 2 is inserted into the housing 3, in one embodiment of the present invention, the inner wall of the slot 30 is provided with a first protruding ridge 35, the length direction of which is parallel to the length direction of the slot 30. To further reduce friction between the two, the outer wall of the first inner core 1 and / or the second inner core 2 is provided with a second protruding ridge 36, the length direction of which is perpendicular to the length direction of the slot 30.
[0045] This utility model provides an innovative replaceable shielding design for a high-voltage connector assembly, including both shielded and unshielded structures. The shielded structure cleverly incorporates a shielding cover 12 and a shielding ring 13 to ensure superior shielding performance, effectively addressing specific application scenarios with stringent shielding requirements. The unshielded structure precisely removes the shielding cover and shielding ring, utilizing a unique design process (the first inner core 1 and the second inner core 2 have the same shape and size) to achieve seamless integration with the housing 3, perfectly adapting to different application scenarios. Through a unified interface (slot 30) within the housing 3, the entire device can be replaced without requiring replacement, significantly improving product compatibility and ease of use, demonstrating significant technological innovation and practicality. This utility model adopts an innovative solution that only requires replacing the inner cores rather than the entire connector, based on cost optimization principles, greatly reducing hardware replacement costs. Simultaneously, from a supply chain management perspective, this solution significantly alleviates inventory pressure and greatly reduces maintenance complexity. By simplifying supply chain management processes, it effectively improves market responsiveness, exhibiting outstanding economic benefits and strong market competitiveness, providing new technical ideas and solutions for the development of related technological fields. This invention provides the industry with a lower-cost and more adaptable solution, which can not only reduce enterprise cost input and improve inventory management efficiency, but also quickly respond to market demands and enhance the competitiveness of the entire industry. At the same time, this invention can also help electrical connection technology move towards green and sustainable development, leading the industry to achieve efficient and environmentally friendly transformation, and making a greater contribution to promoting the development of the new energy electric vehicle industry.
[0046] The above is the first embodiment of this utility model, as follows: Figures 8-11 As shown, this is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the number of the first inner core 1 and the second inner core 2 is 3, that is, the high-voltage connector is a 3-pin connector.
[0047] High-voltage connectors generally include a wire end (with a slot) and a board end (with a plug corresponding to the slot), which are plugged together to achieve electrical connection. The first and second embodiments described above mainly describe the wire end of the high-voltage connector assembly, which has replaceable first inner core 1 and second inner core 2. By selecting different inner cores to insert into the housing 3, the conversion between unshielded and shielded states can be achieved. Figure 12As shown, in the third embodiment of this utility model, the high-voltage connector assembly further includes a plate-end assembly 4. The plate-end assembly 4 includes a plate-end body 41 and a plate-end shielding cover 42 disposed outside the plate-end body 41. The plate-end shielding cover 42 is detachably connected to the plate-end body 41. To correspond to the shielded or unshielded state of the wire end, in this embodiment, the plate-end assembly 4 also includes both shielded and unshielded states. When a shielded state is required, the plate-end shielding cover 42 is disposed outside the plate-end body 41 of the plate-end assembly 4; when an unshielded state is required, since the plate-end shielding cover 42 is detachably connected to the plate-end body 41, it can be removed to achieve the desired state.
[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
