[0023] One of the embodiments of the present application is an electromagnetic shielding shell for a high-voltage connector, as shown in FIGS. 1 and 2, including an integrated barrel-shaped structure 100 that includes a barrel wall 110 and a barrel bottom 120 that are connected to each other.

[0024] The embodiments of the present invention provide an integrated barrel-shaped structure including the barrel wall 110 and the barrel bottom 120, the entire electromagnetic shielding shell does not have structural slits, thereby improving the current passing capacity and electromagnetic shielding performance, and there is no overlap of multiple sheet metal materials in the structure of the electromagnetic shielding shell, and can increase the thickness of the electromagnetic shielding shell under the same conditions, and it can also make the structure thickness of the electromagnetic shielding shell have better uniformity, avoid the situation of thick local structures, and the space occupied by the electromagnetic shielding shell in the high-voltage connector is reduced and materials are saved, which can reduce the material cost and manufacturing cost of the product.

[0025] In one of the embodiments, the barrel bottom 120 is provided with a plurality of through holes 121 for the terminals to pass through, so that the terminals in the high-voltage connector can pass through the electromagnetic shielding shell to meet the structural requirements of some high-voltage connectors. In some other embodiments, the barrel bottom 120 may not be provided with the through holes 121. The terminals in the high-voltage connector can also pass through the electromagnetic shielding shell through the openings of the integrated barrel-shaped structure 100, which meets the structural need of some high-voltage connectors.

[0026] In one of the embodiments, the outer surface of the barrel bottom 120 is provided with the same number of protection rings 130 as through holes 121, and the protection rings 130 surround peripheral edges of the through holes 121, and continuously extend from the barrel bottom 120 along an axial direction of the integrated barrel-shaped structure 100.

[0027] The terminals in the high-voltage connector can pass through the through holes 121 of the barrel bottom 120 and then can pass through the protective rings 130 on the outer surface of the barrel bottom 120. The protective rings 130 can protect and limit the terminals, such that the structure passing through the electromagnetic shielding shell is more stable, to prevent the terminals from bending or deforming.

[0028] In one of the embodiments, the junction between the outer surface of the barrel bottom 120 and the outer surface of the barrel wall 110 and / or the junction between the inner surface of the barrel bottom 120 and the inner surface of the barrel wall 110 is provided with a rounded structure 140 to reduce the stress concentration at the junction of the barrel bottom 120 and the barrel wall 110, which facilitates the assembly of the electromagnetic shielding shell and optimizes the current flow path.

[0029] In one of the embodiments, the junction between the outer surface of the barrel bottom 120 and the outer surface of the protection ring 130 and / or the junction between the inner surface of the ban-el bottom 120 and the inner surface of the protection ring 130 is provided with a rounded structure 140 to reduce the stress concentration at the junction between the barrel bottom 120 and the protection ring 130, which facilitates the assembly of the terminals and optimizes the current flow path.

[0030] In one of the embodiments, the number of the through holes 121 and the number of protection rings 130 are both one or two. so that the electromagnetic shielding shell can be passed through by one or two terminals respectively.

[0031] In one of the embodiments, there are three through holes 121 and three protection rings 130, so that the electromagnetic shielding shell can be passed through by the three terminals.

[0032] In one of the embodiments, the barrel bottom 120 has a circular shape, and the three through holes 121 and the three protection rings 130 are all distributed at equal intervals around a center of the barrel bottom 120 in a ring shape, so that the distribution of the structure and weight of the electromagnetic shielding shell is more even, and the three terminals of the high-voltage connector can pass through the electromagnetic shielding shell neatly.

[0033] In one of the embodiments, the barrel bottom 120 is provided with a plurality of clamping holes 122 for fixing the electromagnetic shielding shell. Correspondingly, a number of hooks are provided in the shell of the high-voltage connector to engage with the clamping holes 122 of the barrel bottom 120. During assembly, the hooks of the shell of the high-voltage connector are snapped into the clamping holes 122 of the barrel bottom 120 of the electromagnetic shielding shell. The electromagnetic shielding shell can be easily fixed into the high-voltage connector and the structure is simple and easy to install.

[0034] In one of the embodiments, the barrel bottom 120 is circular, and three clamping holes 122 are provided. The three clamping holes 122 are distributed at equal intervals around the center of the bottom 120 in a ring shape, so that the electromagnetic shielding shell can be more firmly installed in the high-voltage connector.

[0035] In one of the embodiments, the barrel wall 110 extends continuously along the axial and circumferential directions of the integrated barrel-shaped structure 100, so that the entire barrel wail 110 is structurally free from openings and seals, which results in a better electromagnetic shielding effect.

[0036] In one of the embodiments, the barrel wall 110 is provided with inner and outer surfaces that extend smoothly and continuously, so that neither the inner surface nor the outer surface of the barrel wall 110 has any protrusions or recesses, thereby reducing material costs and manufacturing costs.

[0037] In one of the embodiments, the integrated barrel-shaped structure 100 has a uniform wall thickness. Thus the structure is simple and easy to install, and the current flows through the integrated barrel-shaped structure 100 more smoothly.

[0038] In one of the embodiments, the barrel wall 110 has the same wall thickness along the circumferential direction of the integrated barrel-shaped structure 100. Thus the structure is simple and easy to install, and the current flows through the barrel wall 110 more smoothly.

[0039] In one of the embodiments, the integrated barrel-shaped structure 100 is a structure formed by a deep drawing process. The deep drawing process is also called deep drawing, drawing or calendaring process, and belongs to one of the stamping processes, which is a stamping processing method that uses a mold to turn the blank into a hollow part with openings. The deep drawing process can be used to make thin-walled parts in the shape of barrel, step, cone, sphere, box, etc. When comparing to the process made by turning and other processes, the integrated barrel-shaped structure 100 is made by a deep drawing process which is simple and the cost is lower, and it can have a uniform wall thickness and a smooth surface.

[0040] The embodiment of the present invention also provides a high-voltage connector, which includes a connector housing and an electromagnetic shielding housing as described above. The electromagnetic shielding housing is arranged inside the connector housing. The barrel opening of the integrated barrel-shaped structure 100 is arranged at the mating end of the high-voltage connector. The high-voltage connector can have better current passing capacity and electromagnetic shielding performance, and the electromagnetic shielding shell occupies less space in the high-voltage connector, saves materials, and can reduce material costs and manufacturing costs.

[0041] The above are only some embodiments of the present invention and are not intended to limit the present invention,, and any modification, equivalent replacement and improvement made within the spirit and principle of this invention shall be included within the protection scope of the present application. 28 04 25
