Abstract
The utility model relates to the electrical and electronic field, and especially relates to a three-proofing electronic controller based on hierarchical protective shells. The three-proofing electronic controller comprises a housing, a plug-in piece, a circuit board and a sealing cover. The butt joint parts of the housing and the plug-in piece and the butt joint parts of the housing and the sealing cover are respectively provided with flange disks which are matched with each other. The flange disks are fixedly connected though socket head cap screws. Rubber films are arranged on the contact surfaces. A large-sized electronic element on the circuit board is wrapped in an aluminum protective cover. An accommodating cover is arranged on the housing correspondingly to the aluminum protective cover. Heat radiation fins are arranged outside the accommodating cover. Collision-avoidance blocks are arranged on two sides of the lower end of the circuit board. The three-proofing electronic controller is reasonable in structure design; the hierarchical protective structure is adopted, and the aluminum protective cover, the accommodating cover, the rubber films and the outer composite material protective housing are arranged in sequence from the inner to the outer, so that the three-proofing electronic controller is good in waterproof, shockproof and dustproof performance, and is provided with the electromagnetic protection function to a certain extent; in addition, the structure is compact, the weight is light, the inner electronic elements are effectively protected from being damaged, and the stable operation of the electronic controller is ensured.
Description
Technical field
The utility model relates to electrotechnical, electronic field, especially the three anti-electronic controllers based on level containment vessel.
Background technology
When Electronic Control product is used out of doors, reliability requirement is high, no matter is that bad weather or human factor are fallen it, and electronic product all should be able to normally be worked, and this just requires electronic controller to possess good waterproof and dustproof, shockproof properties.Existing electronic controller, adopts plastics or metal shell conventionally, and the former is lightweight but protective value is poor; the latter's protective value is good but weight is large, especially, for adapting to the electronic component on internal circuit board and circuit board, must size be done greatlyr; then integral installation radiator on shell; on the one hand, this can make the idle space of containment vessel inside very large, has reduced the reliability of electronic controller; on the other hand; radiator body is large, use material is many, has increased cost, is unfavorable for assembling.
The patent No. is a kind of electronic controller of CN200520044904.0, adopted aluminum alloy casing to reduce weight, by separately for large electronic component provides housing to reduce inner idle space, by radiator being set for large electronic component separately, reduced cost, reduced the body of electronic controller, but because adopting normal screws, the connection between its each parts is spirally connected, do not consider to prevent dust in the position that is spirally connected, waterproof, between circuit board and seal cover, also lack necessary precautions against earthquakes, this makes its containment vessel intensity very high, but waterproof, anti-dust performance is poor, and when electronic component is subject to clashing into energetically, circuit board and contacting of inner walls are easy to cause the damage of electronic component, need to innovate improvement.
Utility model content
The purpose of this utility model is to provide the three anti-electronic controllers based on level containment vessel in order to overcome above-mentioned technical disadvantages, makes it possess waterproof, shockproof, dustproof NBC protective performance, solves that electronic devices and components are fragile, the problem of fluctuation of service.
The technical scheme that the utility model technical solution problem adopts is: the three anti-electronic controllers based on level containment vessel, comprise housing, plug connector, circuit board and seal cover, described housing and plug connector docking site, housing is equipped with the mutual ring flange mating with seal cover docking site, ring flange is connected and fixed by soket head cap screw, on contact-making surface, be equipped with rubber film, large size electro sub-element on described circuit board is wrapped in aluminium quality guarantee guard shield, the housing position corresponding with aluminium quality guarantee guard shield is provided with housing, housing outside is provided with radiating fin, both sides, described circuit board lower end are provided with anticollison block.
The inner space of described housing is fitted and is mated mutually with aluminium quality guarantee guard shield, and aluminium quality guarantee guard shield, housing form the electronic component containment vessel of level.Between aluminium quality guarantee guard shield and housing, rubber film is not set, object is to avoid affecting heat conductivility, reduces the radiating efficiency of radiating fin, as long as but guaranteed the close contact between aluminium quality guarantee guard shield and housing, do not affect anti-seismic performance.
Described housing, seal cover are the high strength containment vessel that stainless plate panel is outer, the composite material of aluminum plate internal layer is made.
In the rubber film of described seal cover and housing docking site, be connected to seal cover inwall and with seal cover inwall suitable coupling mutually.
The anticollison block of both sides, described circuit board lower end, it is highly greater than the height of all electronic components in circuit board lower surface.
The beneficial effect that the utility model has is: the utility model reasonable in design; adopt level protection structure; be followed successively by from inside to outside aluminium quality guarantee guard shield, housing, rubber film and outer layer of composite material containment vessel; possess good waterproof, shockproof and anti-dust performance; also possess certain electromagnetic protection function, close structure, lightweight; effectively protection internal electronic component is not damaged, has ensured the stable operation of electronic controller.
