Embodiment
Contrast below
accompanying drawing, by the description to embodiment, the specific embodiment of the present invention is described in further detail.
This
inventionelectric vehicle battery system high voltage protection device,
as Fig. 1shown in, comprise the plug 1 and socket 4 that coordinate grafting.
Plug 1 outside is provided with shell, is provided with the first main contacts 11 and the second main contacts 12 in shell, between the first main contacts 11 and the second main contacts 12, be provided with the fuse 13 being connected to major loop,
as Fig. 2shown in.
as Fig. 4, shown in 5, socket 4 be provided with stretch out to be connected to the cable 6 in cell high voltage loop, socket 4 is provided with and coordinates two of grafting to crimp sleeve 43 with the first main contacts 11 and the second main contacts 12, and cable 6 is connected on crimping sleeve 43.Socket 4 comprises be connected protection bonnet 41 and holder 42, and crimping sleeve 43 and described cable 6 are placed between protection bonnet 41 and holder 42.Wherein protection bonnet 41 and holder 42 are clamping.Holder 42 has the outer that a circle stretches out, and outer is provided with installing hole, is fixedly connected with socket 4 by screw or bolt, has socket seal circle in outer.
Plug 1 and socket 4 are provided with interlock.Interlocking contact pin is located in the shell of plug 1, and socket 4 is provided with and the interlocking sleeve 6 interlocking contact pin and coordinate.Interlocking sleeve 6 is embedded in the holder 42 on socket 4.The plastic casing that interlocking sleeve 6 comprises interlocking plug-in unit and the signal and communication line be connected in battery management system BMS.
