[0022] 1, an embodiment of the present application provides an electromagnetic shielding shell for a high-voltage connector, including a main body 100 and a connecting body 200, and a plurality of elastic arms 300 are provided between the main body 100 and the connecting body 200, with one end of each elastic arm 300 connected to the main body 100 and the other end of each elastic arm 300 connected to the connecting body 200. Each elastic arm 300 is provided with a protrusion 330 that protrudes in the radial direction (i.e., in a direction perpendicular to the axial direction of the main body 100), and the protrusion 330 is used to electrically contact a mating connector.

[0023] In the embodiment of the present application, the elastic arms 300 are disposed between the main body 100 and the connecting body 200 of the electromagnetic shielding shell, and therefore the front and rear ends of the elastic arms 300 are connected to the electromagnetic shielding shell itself (the main body 100 and the connecting body 200 belong to part of the electromagnetic shielding shell). Furthermore, when a shielding current flows through the protrusions 330 of the elastic arms 300, the shielding current can be transmitted to the main body 100 and the connecting body 200 through the two ends of each elastic arm 300, respectively. This prevents the shielding current from being geometrically folded back, and ensures a smooth path for the shielding current, which reduces the loop resistance of the electromagnetic shielding shell and is beneficial to improving the electromagnetic shielding effect.

[0024] In one embodiment, each resilient arm 300 includes a protrusion 330 that protrudes from the outer surface of the body 100 so that the protrusions 330 can make electrical contact with a shielding member of a mating connector.

[0025] In one embodiment, the main body 100 is a ring-shaped structure, and the connecting body 200 is an arc-shaped structure arranged circumferentially around the main body 100, thereby simplifying the structure of the electromagnetic shielding shell and making it not only easier to manufacture but also easier to assemble into high-voltage connectors, etc.

[0026] In one embodiment, the elastic arm 300 is disposed between the main body 100 and the connecting body 200 along the axial direction of the main body 100. This is because, on the one hand, it is possible to expand the shielding space of the electromagnetic shielding shell in the axial direction of the main body 100, and, on the other hand, it is possible to reduce the resistance of the protrusion 330 provided on the elastic arm 300 when assembling the electromagnetic shielding shell to a high-voltage connector or the like.

[0027] In one embodiment, each elastic arm 300 extends between the main body 100 and the protrusion 330 along the axial direction of the main body 100, which provides a simple structure and easy assembly.

[0028] In one embodiment, a plurality of connecting arms 400 are spaced apart between the main body 100 and the connecting body 200, with one end of each connecting arm 400 connected to the main body 100 and the other end connected to the connecting body 200. The connecting arms 400 can improve the shielding effect by blocking or reflecting electromagnetic signals and assisting the flow of shielding current. The connecting arms 400 can also increase the connection strength between the main body 100 and the connecting body 200 to prevent the electromagnetic shield shell from deforming during assembly. Increasing the number of connecting arms 400 also reduces the thickness and width requirements for the elastic arms 300 required by the electromagnetic shield shell as much as possible under the same circumstances. This allows the elastic arm 300 structure to be positioned at corners and curved sections, while still ensuring the electromagnetic shielding effect. The structure of the electromagnetic shield shell can also be adjusted by increasing or decreasing the number and width of the connecting arms 400 or the elastic arms 300 to meet different product requirements, thereby changing the shielding performance and assembly mechanical strength of the electromagnetic shield shell.

[0029] In one embodiment, each linking arm 400 has a linear configuration, and the linking arm 400 is radially spaced from the shielding member of the mating connector such that the surface of the linking arm 400 does not directly contact the shielding member of the mating connector.

[0030] In one embodiment, each connecting arm 400 extends between the main body 100 and the connecting body 200 along the axial direction of the main body 100, which is beneficial for further expanding the shielding space of the electromagnetic shielding shell and further improving the structural strength of the electromagnetic shielding shell.

[0031] In one embodiment, the resilient arms 300 and the connecting arms 400 are alternately arranged between the main body and the connecting body along the circumferential direction of the main body. Because the resilient arms 300 and the connecting arms 400 are alternately arranged, when assembling the electromagnetic shielding shell, the protrusions 330 on each resilient arm 300 can more evenly withstand the resistance of other parts of the high-voltage connector, and at the same time, the connecting arms 400 and the resilient arms 300 can also more evenly withstand the squeezing force from the main body 100 and the connecting body 200, resulting in higher structural strength for the electromagnetic shielding shell.

[0032] In one embodiment, the elastic arms 300 and the connecting arms 400 are evenly spaced around the circumference of the main body 100, which further improves the structural strength of the electromagnetic shielding shell.

[0033] In one embodiment, the connector 200 includes a first connector 210 and a second connector 220 respectively disposed on two opposing sides of the main body 100, and the elastic arm 300 includes a plurality of first elastic arms 310 and a plurality of second elastic arms 320, one end of each first elastic arm 310 being connected to the main body 100 and the other end of each first elastic arm 310 being connected to the first connector 210, one end of each second elastic arm 320 being connected to the main body 100 and the other end of each second elastic arm 320 being connected to the second connector 220. The first connector 210 and the second connector 220 are disposed on opposite sides of the main body 100, with the first elastic arm 310 disposed between the main body 100 and the first connector 210 and the second elastic arm 320 disposed between the main body 100 and the second connector 220. This is beneficial to further reducing the loop resistance of the electromagnetic shielding shell and improving the shielding performance of the electromagnetic shielding shell, as the shielding current can flow to the main body 100 and the first connecting body 210 via the protrusion 330 on the first elastic arm 310, and also to the main body 100 and the second connecting body 220 via the protrusion 330 on the second elastic arm 320.

[0034] In one embodiment, a single first connector 210 is provided, and a plurality of first elastic arms 310 are respectively disposed between the main body 100 and the first connector 210. Because the single first connector 210 is provided, and the plurality of first elastic arms 310 are all disposed between the main body 100 and the first connector 210, the structural stability of the first connector 210 and the first elastic arms 310 can be improved, and the first connector 210, the main body 100, and the plurality of first elastic arms 310 as a whole are not easily deformed.

[0035] In one embodiment, multiple connecting arms 400 are spaced apart between the main body 100 and the first connector 210, with one end of each connecting arm 400 connected to the main body 100 and the other end connected to the first connector 210. Each connecting arm 400 has a flat surface, which can block or reflect electromagnetic signals, promote the flow of shielding current, and improve the shielding effect. Because only one first connector 210 is provided, multiple connecting arms 400 are arranged between the first connector 210 and the main body 100, which can increase the connection strength between the main body 100 and the first connector 210 and prevent the electromagnetic shield shell from easily deforming during assembly. Furthermore, increasing the number of connecting arms 400 can reduce the thickness and width requirements of the first elastic arm 310 as much as possible under the same circumstances, ensuring that the first elastic arm 310 structure can be placed around corners and bends to ensure the electromagnetic shielding effect. Furthermore, in order to meet the requirements of different products, the structure of the electromagnetic shielding shell can be modified by increasing or decreasing the number or width of the connecting arms 400 or the number or width of the first elastic arms 310, thereby changing the shielding performance and mechanical assembly force of the electromagnetic shielding shell.

[0036] In one embodiment, the connecting arm 400 extends along the axial direction of the main body 100. The extending directions of the connecting arm 400 and the first elastic arm s310 are both in the axial direction of the main body 100, which is beneficial for further expanding the shielding space of the electromagnetic shielding shell and further improving the structural strength of the electromagnetic shielding shell.

[0037] In one embodiment, the first resilient arms 310 and the connecting arms 400 are distributed in a staggered pattern between the main body 100 and the first connecting body 210. When assembling the electromagnetic shielding shell, the first resilient arms 310 and the connecting arms 400 are distributed in a staggered pattern, so that the protrusions 330 of each first resilient arm 310 can more evenly withstand the resistance of other parts of the high-voltage connector, and at the same time, the connecting arms 400 and each first resilient arm 310 can more evenly withstand the compressive force from the main body 100 and the first connecting body 210, resulting in higher structural strength for the electromagnetic shielding shell.

[0038] In one embodiment, a plurality of second connectors 220 are provided, and the plurality of second connectors 220 are distributed around the axial direction of the main body 100, with a gap 500 formed between two adjacent second connectors 220. In addition, a plurality of second elastic arms 320 are disposed between each second connector 220 and the main body 100. Compared to the structure of the first connector 210 and the first elastic arm 310, the structural stability of the second connector 220 and the second elastic arm 320 is inferior to that of the first connector 210 and the first elastic arm 310 because a gap 500 is formed between two adjacent second connectors 220 and the plurality of second connectors 220 are not connected to form a whole structure. However, a plurality of second connectors 220 are provided, with a gap 500 formed between two adjacent second connectors 220, and a plurality of second elastic arms 320 are respectively disposed between the plurality of second connectors 220 and the main body 100. During assembly, it is possible to quickly identify which side of the electromagnetic shielding shell is the first elastic arm 310 and which side is the second elastic arm 320, allowing the first elastic arm 310 and the second elastic arm 320 to be accurately assembled to the corresponding positions of a high-voltage connector or the like, and preventing the electromagnetic shielding shell from being reversed forward or backward. Furthermore, the structure of the electromagnetic shielding shell allows the number and width of the second elastic arms 320 to be increased or decreased to meet different product requirements, thereby changing the shielding performance and mechanical assembly force of the electromagnetic shielding shell.

[0039] In one embodiment, the main body 100, the connecting body 200 and the resilient arm 300 are integrally formed, which makes the manufacturing process of the electromagnetic shield shell simpler and provides greater structural stability.

[0040] In one embodiment, the main body 100, the elastic arm 300, and the connector 200 are arranged in this order along the axial direction of the main body 100.

[0041] Furthermore, in the embodiment of the present application, as described above, a high-voltage connector is provided that includes a connector housing (not shown) and an electromagnetic shielding shell, with the electromagnetic shielding shell being disposed inside the connector housing and the connecting body 200 being disposed at the mating end of the mating connector, thereby achieving a higher electromagnetic shielding effect against internal electromagnetic signals.

[0042] The above are only some embodiments of the present application, and are not intended to limit the present application, and any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
