Shielded high-voltage junction box meeting IP67

Abstract

The invention relates to the technical field of lithium-ion battery shells, in particular to a shielded high-voltage junction box meeting IP67; the shielded high-voltage junction box comprises an upper cover component and a base component; the upper cover component comprises an upper metal cover, an upper plastic cover, an upper seal gasket and an upper shielding ring; the upper seal gasket is embedded in the upper plastic cover that is fixed in the upper metal cover, and the upper shielding ring is embedded in the upper metal cover; the base component comprises a lower plastic base, a lower metal base, a lower seal gasket and a lower shielding ring; the lower seal gasket is embedded in the lower plastic base, the lower plastic base is fixed in the lower metal base, and the lower shielding ring is embedded onto the lower metal base; the upper metal cover and the lower metal base are fixedly connected together through fixing bolts. A reliable connection mode for high-voltage wire electrical connection techniques is provided herein, the process is simple, the cost is low, the structure is reliable, and a battery system has improved reliability and safety.

Description

technical field [0001] The invention relates to the technical field of lithium-ion battery shells, in particular to a high-voltage junction box with shielding meeting IP67. Background technique [0002] In the electric vehicle industry, pure electric power and hybrid power put forward higher and higher requirements on the high-voltage connection end of the power battery system. The shielding and IP protection of high-voltage junction boxes have become difficult problems for the industry to overcome. At present, products such as connectors or fixing seats used in the high-voltage power line connection of the new energy vehicle power battery industry are exposed to the outside, which not only has poor waterproof and dustproof effects, but also easily generates electromagnetic interference, which affects the normal operation of other components. pose a safety hazard. A high-voltage power distribution box for an electric vehicle is disclosed in the prior art. Its structure is: ...
