High-voltage wiring box convenient to assemble and disassemble and assembling and disassembling method of high-voltage wiring box

Abstract

The invention relates to a high-voltage junction box which is convenient for installation and disassembly and a disassembly method thereof. The high-voltage junction box that is easy to install and disassemble includes a base, an upper cover connected to the base, and on the panel of the equipment installed on the base. On the terminal post, the upper cover is detachably connected to the base, the radially protruding part of the upper cover is provided with a stop lock, and the corresponding concave part of the base is provided with a stop slot. When the upper cover is screwed to the set position, the stop of the upper cover The position lock slides into the stop groove of the base to lock, and the upper cover cannot be twisted any more. When it needs to be disassembled, pull up the pull ring of the stop lock by hand to unlock and unscrew the upper cover. The disassembly method includes: (1) When installing, screw the upper cover and the base, the stop lock pin slides into the stop slot of the base, and the stop lock is automatically locked; (2) When disassembling, pull up the stop lock pull ring, the stop lock The pin leaves the stop slot, automatically unlocks, and the upper cover is unscrewed.

Description

technical field [0001] The invention relates to a high-voltage power supply connection device for a power battery of a new energy vehicle, in particular to a high-voltage junction box which is easy to install and disassemble and a disassembly method thereof. Background technique [0002] At present, new energy vehicles have become an inevitable trend in the development of the automotive industry, and the application of charging equipment on electric vehicles has become more and more important to people. High-energy power batteries installed on electric vehicles require connectors that can be connected and shielded with high-voltage power supplies, and the connectors are used in vibration and exposed environments for a long time, and the waterproof and dustproof effects are poor, and they are prone to electromagnetic interference. The normal operation of the components poses a safety hazard. The structure of the high-voltage junction box disclosed in the prior art is as foll...
