Summary of the invention
The present invention has overcome the deficiencies in the prior art, and a kind of ECU housing of good waterproof performance is provided, and has solved the poor problem of ECU housing water proofing property in the past.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: a kind of ECU housing of good waterproof performance, comprise base plate and cap, base plate is tetragonal structure, four edges of described base plate are equipped with screwed hole I, described base plate encloses formation installation cavity by dividing plate, and described base plate is provided with seal groove in dividing plate outside; The protruding formation connecting plate of described cap lower end surrounding, four edges of connecting plate are provided with screwed hole II, in the arbitrary side of described cap, be provided with two connection jaws, connection jaws arranged on left and right sides is equipped with screwed hole III, described dividing plate is provided with the structure identical with screwed hole III with connection jaws in relevant position, end face is also provided with the draw-in groove around connection jaws one circle outside described cap.This programme is when application, first sealing ring or fluid sealant will be added in seal groove, then ECU circuit board is arranged in installation cavity, then cap is directly covered and is combined on base plate, cap has the one side of connection jaws and places with the one side that dividing plate has same structure connection jaws, the interface of ECU circuit board stretches out by connection jaws, by screw and screwed hole I, screwed hole II coordinates fixes cap and base plate, when wiring, external lug end is clamped in draw-in groove, and coordinate joint is fixed with screwed hole III by screw, in draw-in groove, also can add sealing ring for enhanced leaktightness waterproof effect, this programme protects ECU circuit board and by seal groove and draw-in groove, internal circuit board and the external world is isolated completely by dividing plate is set, thereby prevents that outside water, wet goods liquid from entering enclosure interior, good water-proof effect, fabulous protection inner ECU circuit board.
Described cap upper surface is evenly distributed with a plurality of fin.In order to strengthen the radiating effect of ECU housing, in cap upper end, be uniformly distributed a plurality of fin, not only increase the heat exchange area of cap and extraneous air, but also increased the intensity of cap, improved the compressive property of cap, practical.
Described base plate is provided with a plurality of insulation fixed legs in installation cavity, and insulation fixed leg is provided with internal thread hole.In order to strengthen the radiating effect of ECU housing, in cap upper end, arrange and be uniformly distributed a plurality of fin, not only increase the heat exchange area of cap and extraneous air, but also increased the intensity of cap, improved the compressive property of cap, practical.
The arbitrary side of described base plate is provided with retainer ring.By retainer ring, base plate can be fixed, prevent displacement.
Described cap inside scribbles one deck heat-conducting glue.For strengthening the radiating effect of cap inside, so cap inside scribbles one deck heat-conducting glue, by heat-conducting glue, accelerate cap and heat exchange with outside, play good cooling-down effect.
Described base plate and cap all adopt magnadure to make.Magnadure not only has certain intensity, and cost is low, is convenient to processing, and quality is light, and thermal conductivity is good, and base plate and cap all adopt magnadure to make the thermal conductivity that can strengthen ECU housing, reduces costs simultaneously, reduces ECU case weight.
Compared with prior art, the invention has the beneficial effects as follows: the ECU housing of this good waterproof performance of the present invention design, simple in structure, easy for installation, and sealing and thermal diffusivity good, waterproof effect is remarkable, practical.
