High-voltage connector for new energy vehicle

Abstract

The invention discloses a high-voltage connector for a new energy vehicle. The high-voltage connector comprises a copper bar, a metal shell, a metal cover, an insulating protective shell, an insulating protective cover, a metal terminal, a shielding mechanism and a rear cover, and the metal shell and the metal cover form a first accommodating cavity; a first opening and a second opening are respectively formed in the side wall and the bottom of the metal shell; the insulating protective shell and the insulating protective cover are buckled to form a second accommodating cavity; and the copperbar is arranged in the second accommodating cavity and protrudes out of the insulating protective shell, the copper bar extends outwards from the first opening and is perpendicular to the metal shell,the shielding mechanism and the rear cover are arranged on a high-voltage wiring harness in a sleeving mode and connected with the copper bar through metal terminals, and the shielding mechanism is fixed to the metal shell through the rear cover. A right-angle structure is adopted, so that the installation requirement space of the high-voltage connector and an electric appliance is reduced; the insulating protective shell uses an internal secondary locking structure to replace a high-voltage interlocking loop, thereby ensuring that the insulating protective shell cannot be disassembled from the outside of the high-voltage connector, and reducing the overall cost of the high-voltage connector under the condition of ensuring personnel safety.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a high-voltage connector used for new energy vehicles. Background technique [0002] At present, new energy high-voltage connectors are mainly quick-plug connectors and 180-hole installation connectors. There is a large demand for wiring space for high-voltage wiring harnesses in automobiles. Some narrow spaces cannot meet the wiring requirements. In addition, quick-connect connectors require additional The high-voltage interlock circuit is complex and costly; at the same time, the EMC performance brought about by the shielding contact structure of the high-voltage connector of the new energy vehicle is poor. Contents of the invention [0003] Aiming at the defects of the above prior art, the main purpose of the present invention is to overcome the deficiencies of the prior art, and discloses a high-voltage connector for new energy vehicles, including a copper bar, a metal sh...
