Abstract

The invention discloses a high-voltage distribution cabinet of an electric vehicle. The cabinet comprises a cabinet body and a cabinet cover. A concave cavity is formed in the cabinet body and internally provided with a circuit board, a current detector, a fuse, thermistors, a relay, a copper bar and a wire. A plurality of electrically connected connectors are arranged on the outer wall of the cabinet body, a boss is circumferentially arranged on the end face of an opening of the concave cavity of the cabinet body, the cabinet cover is provided with a groove matched with the boss in a clamped mode, and a rubber ring is disposed in the groove. By means of the connectors, electricity allocated into the high-voltage distribution cabinet is transmitted to various electric appliances, the protection grade of the cabinet body can be improved, and a good fool-proof function can be achieved. The positive temperature thermistor and the negative temperature thermistor can effectively prevent the situation that a circuit is too hot and accordingly resistors and elements are burnt, and the safety coefficient of equipment is improved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a high-voltage distribution box for electric vehicles. Background technique [0002] In today's energy shortage, electric vehicles have become more and more popular. The high voltage of electric vehicles has broken the 12V or 24V low-voltage electrical environment of traditional vehicles. The high-voltage power distribution box is like a traditional car power distribution box. The layout and use of numerous connecting wire harnesses, relays, fuses and other components will consider higher and safer electrical environment requirements. High-voltage power distribution boxes The structural design of the electric box must be safe and reliable. [0003] The function of the high-voltage distribution box is to distribute the electric energy transmitted by the battery pack to various electrical equipment. However, most of the high-voltage distribution boxes on the market cur...
