Under the promotion of national industrial policies; New-energy automobile has received the very big attention of each auto vendor; And high voltage distribution box is the integrated of vehicle complete vehicle electrical control device, indispensable parts when being operation, and its performance quality will directly influence the quality of vehicle performance.The high voltage distribution box of traditional electric automobile, not only complex structure can not be applicable to a plurality of occasions flexibly, and be not easy repair demolition, poor sealing, water proofing property is poor, a little less than the anti-electromagnetic interference capability; Simultaneously, under the electric automobile high-pressure situations, inner arc resistant breakdown capability, anti-pressure ability and anti-make-break capacity all very a little less than, thereby use fail safe and reliability is all good inadequately, had a strong impact on the electric automobile serviceability.
Given this, the high voltage distribution box that in another Chinese patent 201020238966.6, proposes comprises main cartridge, and a side of main cartridge is being communicated with the fuse box body; The main cartridge that is communicated with the place with the fuse box body is provided with the insurance insulation board, is provided with two D.C. contactors, insulating monitoring module and binding post in the main cartridge, and lateral surface is provided with two multicore connectors up and down side by side; Insurance vertically is provided with three mini fuse silks and a big fuse on the insulation board side by side, and fuse box body bottom is provided with four single core connectors side by side, between big fuse and the single core connector with quadrature L shaped to be connected copper sheet continuous.Though the connector of this patent can plug timely and conveniently; Inspection and to change fuse convenient, and the high-voltage safety property of electric automobile increases, but this high voltage distribution box adopts is plain conductor; This plain conductor is not only laid cumbersome, and high-voltage resistance capability is weak, unreliable.
What propose at another Chinese patent 200620109769.8 is a kind of high voltage power distribution cartridge of hybrid vehicle, comprises box body, it is characterized in that: on box body, establish first water joint, second water joint and the 3rd water joint; In box body, be provided with main relay, current transformer, pre-charge resistance, pre-charge-relay, cooling fan relay, BCM control relay, IPU control relay, the control relay that powers on, pre-charge resistance; Pre-charge resistance and pre-charge-relay loop and main relay are connected in the input and the output of high voltage power power supply simultaneously; Current transformer is as independent loop.Though this high voltage distribution box compact conformation, little, the simple installation of volume; Can satisfy the waterproof and dustproof of automobile controller, the requirement of anti-electromagnetic interference, but its inner plain conductor that adopts connects each components and parts, not only anti-high pressure ability, anti-make-break capacity is not good enough, and circuit safety, reliable inadequately.
In sum, existing high voltage distribution box also is necessary further perfect.
Summary of the invention
The utility model is in order to adopt plain conductor as connecting lead in the high voltage distribution box that solves existing electric automobile; Mounting arrangement is complicated, dismounting is loaded down with trivial details; And the problem that the circuit high-voltage resistance capability is weak and propose a kind of with the copper winding displacement as lead, have simple in structurely, compact, install simply, convenient disassembly; And high-voltage resistance capability is strong, the high voltage distribution box of circuit safety, reliable electric automobile.
The utility model is realized through following technical scheme:
The high voltage distribution box of above-mentioned a kind of electric automobile, said block terminal comprise box body, are installed in the connector of said box body and the contactor that is electrically connected with said connector; Said connector is connected through copper bar with contactor.
The high voltage distribution box of said electric automobile, wherein: said box body comprises casing and loam cake; Be provided with seal washer between said casing and the said loam cake.
The high voltage distribution box of said electric automobile, wherein: said block terminal also includes mounting bracket, and said mounting bracket is installed in two relative lateral walls of said box body.
The high voltage distribution box of said electric automobile, wherein: said block terminal also comprises preliminary filling resistance and the fuse that is electrically connected with said connector.
The high voltage distribution box of said electric automobile, wherein: all be connected between said preliminary filling resistance and fuse and the said connector through copper bar.
Beneficial effect:
The high voltage distribution box of the utility model electric automobile is simple in structure, firm; And assembling is easily, dismantle easy to maintenance, sealing and good waterproof performance; Especially main circuit adopts the copper winding displacement as lead; Connect each components and parts, have the characteristics of the strong and excellent in durability of simple in structure, compactness and reliable, high pressure resistant, the anti-current switching ability of circuit, use safer, reliable.
