[Effects of the Invention]

[0016] Embodiments of the present invention have at least the following beneficial effects: By providing an integrated barrel-shaped structure, the entire electromagnetic shielding shell does not have any structural slits, thereby improving current-carrying capacity and electromagnetic shielding performance; and, since there is no overlap of multiple sheet metal materials in the electromagnetic shielding shell structure, the thickness of the electromagnetic shielding shell can be increased under the same conditions. Furthermore, the thickness of the electromagnetic shielding shell structure can be made more uniform, preventing localized structural thickening. This reduces the space occupied by the electromagnetic shielding shell within the high-voltage connector, saving materials and reducing the material and manufacturing costs of the product.

[0020] One embodiment of the present application is an electromagnetic shielding shell for a high-voltage connector, which includes an integrated barrel-shaped structure 100 including a barrel wall portion 110 and a barrel bottom portion 120 that are connected to each other, as shown in Figures 1 and 2.

[0021] The embodiment of the present application provides an integrated barrel-shaped structure including a barrel wall 110 and a barrel bottom 120, and the entire electromagnetic shielding shell does not have any structural slits, thereby improving the current passing capacity and electromagnetic shielding performance. There is no overlap of multiple sheet metal materials in the electromagnetic shielding shell structure, which allows the thickness of the electromagnetic shielding shell to be increased under the same conditions. In addition, the uniformity of the thickness of the electromagnetic shielding shell structure can be improved, preventing the structure from being thickened in local areas. The space occupied by the electromagnetic shielding shell in the high-voltage connector can be reduced, saving material and reducing the material and manufacturing costs of the product.

[0022] In one embodiment, the barrel bottom 120 is provided with a plurality of through holes 121 for terminals to pass through, allowing the terminals of the high-voltage connector to pass through the electromagnetic shielding shell and meet the structural requirements of some high-voltage connectors. In other embodiments, the barrel bottom 120 may not be provided with the through holes 121. In this case, the terminals in the high-voltage connector can also pass through the electromagnetic shielding shell through the openings of the integrated barrel-type structure 100, meeting the structural requirements of some high-voltage connectors.

[0023] In one embodiment, the outer surface of the barrel bottom 120 is provided with protective rings 130, the number of which is equal to the number of through holes 121, and the protective rings 130 surround the peripheral edges of the through holes 121 and extend continuously from the barrel bottom 120 along the axial direction of the integrated barrel-shaped structure 100.

[0024] After passing through the through-hole 121 in the barrel bottom 120, the terminal of the high-voltage connector can pass through a protective ring 130 provided on the outer surface of the barrel bottom 120. The protective ring 130 can protect and restrict the terminal so that the structure passing through the electromagnetic shielding shell is more stable, and can prevent the terminal from bending or deforming.

[0025] In one embodiment, 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 includes a rounded structure 140 to reduce stress concentrations at the junction between the barrel bottom 120 and the barrel wall 110, facilitate assembly of the electromagnetic shielding shell, and optimize current flow paths.

[0026] In one embodiment, rounded structures 140 at the junction between the outer surface of the barrel bottom 120 and the outer surface of the guard ring 130 and / or the junction between the inner surface of the barrel bottom 120 and the inner surface of the guard ring 130 reduce stress concentrations at the junction between the barrel bottom 120 and the guard ring 130, facilitate assembly of the terminal, and optimize the flow path of electrical current.

[0027] In one embodiment, the number of through holes 121 and the number of protective rings 130 are both provided as one or two, allowing the electromagnetic shielding shell to pass through one or two terminals.

[0028] In one embodiment, there are three through holes 121 and three protective rings 130, and the electromagnetic shielding shell can pass through three terminals.

[0029] In one embodiment, the barrel bottom 120 is arranged in a circular shape, and the three through holes 121 and three protective rings 130 are all arranged in a ring shape at equal intervals around the center of the barrel bottom 120, which makes the structure and weight distribution of the electromagnetic shielding shell more even and allows the three terminals of the high-voltage connector to pass through the electromagnetic shielding shell properly.

[0030] In one embodiment, the barrel bottom 120 is provided with a plurality of clamp holes 122 for securing the electromagnetic shielding shell. Correspondingly, the shell of the high-voltage connector is provided with a number of hooks that engage with the clamp holes 122 in the barrel bottom 120. During assembly, the hooks on the shell of the high-voltage connector fit into the clamp holes 122 in the barrel bottom 120 of the electromagnetic shielding shell. The electromagnetic shielding shell can be secured to the high-voltage connector, has a simple structure, and is easy to install.

[0031] In one embodiment, the barrel bottom 120 is circular and has three clamp holes 122. The three clamp holes 122 are arranged in a ring shape at equal intervals around the center of the bottom 120, allowing the electromagnetic shielding shell to be more securely attached to the high-voltage connector.

[0032] In one embodiment, the barrel wall 110 extends continuously along the axial and circumferential directions of the integrated barrel structure 100, and the entire barrel wall 110 is structurally free of openings and seals, thereby providing superior electromagnetic shielding.

[0033] In one embodiment, the barrel wall 110 has smooth, continuous inner and outer surfaces, which eliminates protrusions and depressions on either the inner or outer surfaces of the barrel wall 110, thereby reducing material and manufacturing costs.

[0034] In one embodiment, the integrated barrel structure 100 has a uniform wall thickness, is simple in construction and easy to install, and allows electrical current to flow more smoothly through the integrated barrel structure 100.

[0035] In one embodiment, the barrel wall 110 has the same wall thickness along the circumference of the integrated barrel structure 100, which is simpler in construction and installation, and allows electrical current to flow more smoothly through the barrel wall 110.

[0036] In one embodiment, the integrated barrel-shaped structure 100 is a structure formed by a deep drawing process. Deep drawing, also known as deep drawing, drawing, or calendaring, is a stamping process in which a blank is converted into a hollow part with an opening using a die. Deep drawing can be used to create thin-walled parts in shapes such as barrels, stepped parts, cones, spheres, and boxes. Compared to processes such as turning, the integrated barrel-shaped structure 100 is formed by a deep drawing process, which is simpler and less expensive, and can have a uniform wall thickness and a smooth surface.

[0037] Furthermore, an embodiment of the present application provides a high-voltage connector including the above-described connector housing and an electromagnetic shielding housing. The electromagnetic shielding housing is disposed inside the connector housing. The barrel opening of the integrated barrel-shaped structure 100 is disposed at the mating end of the high-voltage connector. The high-voltage connector can have better current-passing performance and electromagnetic shielding performance, and the electromagnetic shielding shell does not occupy space within the high-voltage connector, saving material and reducing material and manufacturing costs.

[0038] 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 fall within the protection scope of the present application.
