Description
Technical field
The present invention relates to electrical equipment electromagnetic compatibility technology, be specifically related to the electromagnetic armouring structure of the electrical equipment of a kind of band connecting lead wire.
Background technology
Electromagnetic compatibility is a pressure standard of car electrics parts, new forms of energy electric machine controller is because needing to carry out the control of forceful electric power, high frequency, the radiation-emitting energy of hardware circuit is the highest, and therefore housing radiation-emitting energy to hardware circuit of need to adopting an effective measure when design shields.The environment that uses of vehicle requires that again controller must possess certain dust and water protection performance simultaneously, and controller and lead-in wire thereof have good shock resistance.
The patent of Publication No. CN102438433 A discloses a kind of electromagnetic shielding structure of junction box of motor controller, this patent includes box body, the electromagnetic shielding baffle plate being made up of metal overhead gage and the upper and lower split of metal lower baffle plate it is provided with at the line outlet of box body, overhead gage and lower baffle plate offer the arc notch passed for wire harness in its mosaic, the insulating barrier at position of being matched with arc notch by cable is peelled off, expose wire netting, and on wire netting, it is wound around Copper Foil, work as box body, after cable and lid assembling, on, Copper Foil is firmly pushed down by the arc notch of lower baffle plate, with formation loop, junction box space, cable is completely enclosed within to extraradial electromagnetic wave the inner space of rosette, therefore there is preferable effectiveness, but it is dust-proof, waterproof and shock resistance is the best, and processing inconvenience.
In order to make electromagnetic shielding rosette have good dust-proof, waterproof and shock resistance, also have and upper and lower baffle plate General Purpose Rubber or the magnetic conduction rubber of electromagnetic shielding rosette are manufactured, controller lead-in wire position is sealed.But the sealing means of General Purpose Rubber is almost without effectiveness, and magnetic conduction rubber is with high costs, the easy fragmentation when judder, and reliability is the best.
Summary of the invention
It is an object of the invention to provide the electrical equipment electromagnetic armouring structure of a kind of band connecting lead wire, both there is good effectiveness, there is again the most dust-proof, waterproof and shock resistance, and there is preferable effectiveness.
The electrical equipment electromagnetic armouring structure of band connecting lead wire of the present invention, including box body, the electromagnetic shielding baffle plate being made up of the upper and lower split of overhead gage and lower baffle plate it is provided with at the line outlet of box body, overhead gage and lower baffle plate offer the arc notch passed for wire harness in its mosaic, groove is offered along longitudinal at the end face of overhead gage and the bottom surface of lower baffle plate, upper, the through hole connected with arc notch by groove is offered along the vertical direction on lower baffle plate, on, rubber seal it is injection molded with on lower baffle plate, rubber seal is by strip pad, connect post and arc spacer composition, strip pad is positioned at groove, and the strip pad being positioned at overhead gage groove protrudes from overhead gage end face, connect post and be positioned at through hole, arc spacer is positioned at the surface of arc notch.
It is each provided with convex tendon along the vertical direction in the left and right sides of box body line outlet, on two ends, the left and right end face of overhead gage and lower baffle plate, respectively offers the chute matched 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 putting into the arc notch of lower baffle plate, after each wire harness installs, overhead gage is arranged on box body, finally covers junction box cover plate, and be tightened by bolts.
The simple in construction of the present invention, low cost, wire harness, under the effect of high pressure, is closed between box body, junction box cover plate and electromagnetic shielding baffle plate in the cavity surrounded to extraradial electromagnetic wave, and does not disturb other electric component, therefore there is good capability of electromagnetic shielding, improve the reliability of product.Owing to 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 is not only able to reliably be compressed by electromagnetic shielding baffle plate, it is made to be unlikely to teetertotter and cause unnecessary abrasion and abnormal sound, flexibly connecting so that formed between electromagnetic shielding baffle plate and junction box cover plate, strip pad is absorbable and reduces from electromotor and the vibration on road surface.Make to be formed between wire harness and upper and lower baffle plate flexible contact by arc spacer, avoid the Insulation Problems that wire harness occurs because of friction, arc spacer has bigger decrement simultaneously, it can be ensured that the sealing between electromagnetic shielding baffle plate and wire harness, it is ensured that dust-proof, the waterproof and shock resistance of electrical equipment.
