Description
Technical field
The present invention relates to electrical equipment electromagnetic compatibility technology, be specifically related to a kind of electromagnetic armouring structure of the electrical equipment with connecting lead wire.
Background technology
Electromagnetic compatibility is a pressure standard of car electrics parts, new forms of energy electric machine controller is because carrying out the control of forceful electric power, high frequency, the radiation-emitting energy of hardware circuit is very high, so housing need be adopted an effective measure the radiation-emitting energy of hardware circuit is shielded when design.Simultaneously the environment for use of vehicle requires again controller must possess certain dust and water protection performance, and controller and lead-in wire thereof have good shock resistance.
Publication number is that the patent of CN102438433 A discloses a kind of electromagnetic shielding structure of junction box of motor controller, this patent comprises box body, the line outlet place of box body is provided with by metal overhead gage and the upper and lower overlapping electromagnetic shielding baffle plate forming of metal lower baffle plate, overhead gage and lower baffle plate offer the arc notch passing for wire harness at its overlapping, the insulating barrier at position that cable is matched with arc notch is peelled off, expose wire netting, and on wire netting, be wound around Copper Foil, work as box body, after cable and lid assembling, on, the arc notch of lower baffle plate is firmly pushed down Copper Foil, with formation loop, terminal box inner space, cable is completely enclosed within to the inner space of terminal box to extraradial electromagnetic wave, therefore there is good effectiveness, but dustproof, waterproof and shock resistance are not good, and processing is inconvenient.
In order to make electromagnetic shielding terminal box there is good dustproof, waterproof and shock resistance, also have the upper and lower baffle plate of electromagnetic shielding terminal box is manufactured with General Purpose Rubber or magnetic conduction rubber, controller lead-in wire position is sealed.But the sealing means of General Purpose Rubber does not almost have effectiveness, and magnetic conduction rubber is with high costs, easily cracked when judder, and reliability is not good.
Summary of the invention
The object of this invention is to provide a kind of electrical equipment electromagnetic armouring structure with connecting lead wire, both there is good effectiveness, there is again preferably dustproof, waterproof and shock resistance, and there is good effectiveness.
Electrical equipment electromagnetic armouring structure with connecting lead wire of the present invention, comprise box body, the line outlet place of box body is provided with by overhead gage and the upper and lower overlapping electromagnetic shielding baffle plate forming of lower baffle plate, overhead gage and lower baffle plate offer the arc notch passing for wire harness at its overlapping, at the end face of overhead gage and the bottom surface of lower baffle plate, longitudinally offer groove, upper, on lower baffle plate, offer along the vertical direction the through hole that groove is communicated with arc notch, on, on lower baffle plate, injection mo(u)lding has rubber seal, rubber seal is by strip pad, joint pin and arc pad form, strip pad is positioned at groove, and the strip pad that is positioned at overhead gage groove protrudes from overhead gage end face, joint pin is positioned at through hole, arc pad is positioned at the surface of arc notch.
The left and right sides at box body line outlet is respectively provided with convex tendon along the vertical direction, on the end face of the two ends, left and right of overhead gage and lower baffle plate, respectively offer along the vertical direction the chute matching with this convex tendon, and this convex tendon is positioned at this chute.
During installation, first lower baffle plate is arranged on box body, then by each wire harness by the arc notch of putting into lower baffle plate, after each wire harness installs, overhead gage is arranged on box body, finally cover junction box cover plate, and be tightened by bolts.
Of the present invention simple in structure, cost is low, wire harness is under the effect of high pressure, to extraradial electromagnetic wave, be closed in the cavity surrounding between box body, junction box cover plate and electromagnetic shielding baffle plate, and do not disturb other electric component, therefore there is good capability of electromagnetic shielding, improved the reliability of product.Because the strip pad of rubber seal protrudes from overhead gage end face, on electromagnetic shielding baffle plate, the end face of strip pad is higher than the installed surface of junction box cover plate, after junction box cover plate is installed, junction box cover plate not only can compress electromagnetic shielding baffle plate reliably, make it be unlikely to teetertotter and cause unnecessary wearing and tearing and abnormal sound, but also make to form and flexibly connect between electromagnetic shielding baffle plate and junction box cover plate, strip pad can absorb and reduce the vibration from engine and road surface.By arc pad, make to form flexible contact between wire harness and upper and lower baffle plate, the Insulation Problems of avoiding wire harness to occur because of friction, simultaneously arc pad has larger decrement, can guarantee the sealing between electromagnetic shielding baffle plate and wire harness, has guaranteed dustproof, waterproof and the shock resistance of electrical equipment.
