The present application provides a high-voltage connector and an electromagnetic shielding shell for the high-voltage connector, the electromagnetic shielding shell has an integrated barrel-shaped structure formed by a deep drawing process, and integrated barrel-shaped structure includes a barrel wall and a barrel bottom that are connected to each other. By providing an integrated barrel-shaped structure formed by the deep drawing process, 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 structure, 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.
