[0001] This utility model relates to the field of electrical component technology, and in particular to a high-voltage connector assembly. Background Technology

[0002] Driven by the surging tide of electrification, high-voltage connectors, serving as bridges for energy and information flow, play an indispensable role in numerous cutting-edge fields such as electric vehicles, new energy infrastructure, rail transit, and industrial automation. With the diversification of technical standards and the rapid expansion of application scenarios, the market has placed unprecedentedly high standards on the compatibility and flexibility of high-voltage connectors, requiring them to ensure efficient power transmission while adapting flexibly to different environments. Therefore, products need to exhibit two states: shielded and unshielded. This presents a significant challenge to connector design intelligence and maintenance strategies. Traditional solutions, such as replacing the entire set of connectors to meet different shielding requirements, have revealed their limitations: they not only significantly increase the hardware cost burden and inventory control complexity for enterprises but also appear slow and inflexible in the face of rapidly changing market demands. Lengthy procurement chains and complex replacement procedures not only delay system response speed but also lead to unnecessary downtime and resource waste, affecting the smooth operation of overall business.

[0003] Therefore, there is a need to provide an improved technical solution that addresses the shortcomings of the existing technology. Utility Model Content

[0006] A high-voltage connector assembly includes a housing and an inner core; the housing has a slot for inserting the inner core; the two ends of the inner core are a first end and a second end, which are arranged sequentially along the direction in which the inner core is inserted into the slot; a plurality of positioning blocks are provided on the outer periphery of the first end of the inner core, the positioning blocks extending in a direction perpendicular to the length direction of the inner core; the ends of the positioning blocks abut against the inner wall of the slot, and an annular installation space is formed between the side wall of the inner core and the inner wall of the slot, the installation space being provided with a cylindrical shield.

[0007] According to one embodiment of the present invention, the second end of the inner core is provided with a positioning protrusion extending along the length direction of the inner core, and the end of the positioning protrusion abuts against the inner end of the slot; a plate-shaped installation gap is formed between the second end of the inner core and the inner end of the slot; a baffle is provided at one end of the shield corresponding to the second end, the baffle is located in the installation gap, and the baffle is provided with a clearance hole corresponding to the positioning protrusion.

[0008] According to one embodiment of the present invention, the inner core includes a first inner core and a second inner core that are interlocked with each other.

Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0035] like Figures 1-6 , Figure 11 As shown, this embodiment of the present invention provides a high-voltage connector assembly, including a housing 1 and an inner core 2. The housing 1 has a slot 11 for inserting the inner core 2. The two ends of the inner core 2 are a first end 21 and a second end 22, which are arranged sequentially along the direction in which the inner core 2 is inserted into the slot 11. A plurality of positioning blocks 23 are provided on the outer periphery of the first end 21 of the inner core 2, and the positioning blocks 23 extend in a direction perpendicular to the length direction of the inner core 2. When the inner core 2 is inserted into place, the ends of the positioning blocks 23 abut against the inner wall of the slot 11, and an annular installation space 12 is formed between the side wall of the inner core 2 and the inner wall of the slot 11. A cylindrical shielding cover 3 is provided in the installation space 12.

[0036] The high-voltage connector assembly provided in this embodiment of the invention can provide both shielded and unshielded functions, such as... Figures 1-3 As shown, when the product's surrounding environment requires shielding, first insert the shielding cover 3 into the slot 11 of the housing 1, and finally insert the inner core 2 into the shielding cover 3; Figures 10-12As shown, when the surrounding environment of the product does not require shielding, the inner core 2 can be directly inserted into the slot 11 of the housing 1. Since the positioning block 23 at the first end 21 of the inner core 2 abuts against the inner wall of the slot 11, it provides positioning functionality, ensuring the accuracy and stability of the inner core 2 connection. This invention innovatively introduces a detachable shielding cover technology, and removing the shielding cover 3 does not affect the positioning and installation of the inner core 2. This invention can flexibly adapt to the different needs of shielded and unshielded systems in a low-cost manner, fundamentally resolving the contradiction between compatibility and cost control, and solving the problem of high costs caused by traditional complete replacement solutions.

[0037] like Figure 2 As shown, in one embodiment of this utility model, the shape and size of the shield 3 are the same as those of the installation space 12.

[0038] To further improve the effectiveness of the shielding function, such as Figure 2 , Figure 4 , Figures 7-9 , Figure 11 As shown, in one embodiment of this utility model, a baffle 31 is provided at one end of the shielding cover 3 corresponding to the second end 22, enclosing the second end 22 of the inner core 2 within the shielding cover 3. To address the issue of the inner core 2's length dimension increasing or decreasing due to the installation and removal of the shielding cover 3, in this embodiment, the second end 22 of the inner core 2 is provided with a positioning protrusion 24 extending along the length direction of the inner core 2. When the inner core 2 is inserted into place, the end of the positioning protrusion 24 abuts against the inner end of the slot 11, forming a plate-shaped installation gap 13 between the second end 22 of the inner core 2 and the inner end of the slot 11. The baffle 31 is located within the installation gap 13, and the baffle 31 is provided with a clearance hole corresponding to the positioning protrusion 24. Preferably, the shape and size of the baffle 31 are the same as the installation gap 13. In this embodiment, regardless of whether the shielding cover 3 is installed, the second end 22 of the inner core 2 abuts against the inner end of the slot 11 through the positioning protrusion 24 to achieve precise positioning. Moreover, after the shielding cover 3 is installed, the shielding effect is improved due to the presence of the baffle 31.

[0039] like Figure 3 , Figure 11 , Figure 12 As shown, in one embodiment of the present invention, the inner core 2 includes a first inner core 25 and a second inner core 26 that are interlocked with each other. Further, in this embodiment, the positioning block 23 is disposed at the end of the first inner core 25, and the positioning protrusion 24 is disposed at the end of the second inner core 26.

[0040] like Figure 1 , Figure 3 , Figure 10 , Figure 12As shown, in one embodiment of this utility model, the inner core 2 is provided with two pins 27, that is, the inner core 2 is a 2PIN inner core.

[0041] like Figure 2 , Figure 3 , Figure 11 , Figure 12 As shown, in one embodiment of the present invention, the housing 1 is cylindrical, and a first opening 14 and a second opening 15 are respectively provided at both ends of the housing 1. Further, the opening directions of the first opening 14 and the second opening 15 are opposite and parallel to the length direction of the housing 1.

[0042] like Figure 2 , Figure 3 , Figure 11 , Figure 12 As shown, to achieve the positioning of the inner core 2, spring tabs 28 are provided on both sides of the inner core 2, and recessed holes 16 corresponding to the spring tabs 28 are provided on both sides of the housing 1. After the inner core 2 is inserted into the slot 11, the end of the spring tab 28 is located in the recessed hole 16. In this embodiment, the side wall of the shielding cover 3 is provided with a through hole 32 corresponding to the spring tab 28, so that the spring tab 28 can slide into the recessed hole 16 after the shielding cover 3 is installed. Specifically, in this embodiment, the spring tab 28 is located inside the first end 21 of the inner core 2.

[0043] like Figure 3 , Figure 12 As shown, in one embodiment of the present invention, the high-voltage connector assembly further includes a retaining cover 4, which is disposed at the outer end of the slot 11 and detachably connected to the housing 1, thereby confining the inner core 2 and the shielding cover 3 within the housing 1. In this embodiment, the retaining cover 4 is annular.

[0044] 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. This embodiment mainly describes the wire end of the high-voltage connector assembly, which has a removable shield 3. By selecting whether to install the shield 3, the unshielded and shielded states can be switched. This utility model has the following advantages:

[0045] 1. Removable shielding cover design: This utility model can achieve both shielding and unshielding functions. When shielding, the shielding cover is included to ensure electromagnetic compatibility; when unshielding, the shielding cover is removed to ensure seamless integration with the unshielded system.

[0046] 2. Cost Savings: This invention achieves both shielding and unshielding functions by only removing and installing the shielding cover, rather than the entire connector. This significantly reduces hardware replacement costs, directly decreasing overall costs and production complexity, while also reducing inventory pressure and maintenance complexity. This design simplifies supply chain management and improves market responsiveness.

[0047] 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.
