Abstract
This invention relates to a shell of a double-conjugated L-shaped large power electronic ballast including: a lower L-shaped shell, an upper L-shaped shell, a first side cover, a second side cover, two convex/concave points, in which, the two L-shaped shells in a same shape and size form a master shell by conjugating the two points, the end surfaces of both sides of the master shell are square, the two side covers are fixed at the cross sections of both ends and the two conjugated points are in the shape of the nominal convex/concave .
Description
Technical field
What the present invention relates to is a kind of shell, specifically, is a kind of dual L seamless high power electronic amperite housing, belongs to the electronic assemblies technical field.
Background technology
Various types of in the past great-power electronic ballast shell ubiquities following problem: circuit board can only be packed under all situations of all debugging.Can't debug or detect maintenance after packing into.High power valve generally is to be fixed on by screw to reach radiating effect on the housing, but installs very difficulty.
Find through literature search: Chinese patent publication number 1376024 prior art, open day is on October 23rd, 2002, patent name is: the power electronic ballast sealed heat-dissipating casing, this patent readme is: " sealed heat-dissipating casing for great-power electronic ballast disclosed by the invention; this shell is cuboid; be provided with the slot that electronic circuit board is installed in the shell; skeleton is installed in the heat radiation that also is provided with power tube; this skeleton connects or continuous casting with heat-dissipating casing; this shell also has the sealing cap, the introducing wire hole is arranged on the cap, cap is connected with shell by seal washer, it is introduced also has sealing orifice ring and clamp nut to seal on the wire hole, the sealed heat-dissipating casing of this ballast makes inner power device area of dissipation increase to whole housing, and this housing still seals, and the work safety that helps great-power electronic ballast is with stable." its weak point is: install high power valve concentratedly at housing bottom, not only install extremely difficultly, and thermal source is concentrated unfavorable again heat radiation.Electrical quantity when not putting into housing and pack into after utilize between the housing electrical quantity in when heat radiation and can be very different.The back being installed as debugging and keep in repair, will be very to bother and irrational technology.In addition, pfc circuit high power valve and half-bridge circuit high power valve be fitted together also can cause serious each other high-power RF to disturb, make circuit itself extremely unstable.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of dual L seamless high power electronic amperite housing is provided, it was both dispelled the heat fully effectively by the shell that has increased area of dissipation, be convenient to the installation and the debugging of opening wide again, simultaneously can be with pfc circuit high power valve and half-bridge circuit high power valve away from being installed in diverse location respectively, the high-power RF interference between not only having disperseed pyrotoxin but also avoided mutually.
The present invention is achieved by the following technical solutions, the present invention includes: bottom L shell body, top L shell body, first side cover, second side cover, concavo-convex meeting point, two places, two the identical bottom of shape and size L shell bodies form L type main casing with top L shell body by relative the agreeing with in concavo-convex meeting point, two places, two end sections of L type main casing are square, first side cover and second side cover are fixed on by screw on two end sections of L type main casing, and concavo-convex meeting point, described two places is the concave-convex of nominal dimension unanimity.
Concavo-convex meeting point, described two places, its spill is chosen plus tolerance, and convex is chosen negative common difference, makes to keep three grades of interference fit when agreeing with.
The center size of concavo-convex meeting point, described two places must be consistent.
Described L type main casing, its surface is the heat radiation convex.Height of projection and width can be decided in its sole discretion on demand, and heat radiation bossing surface area is big more, and radiating effect is obvious more.
Operation principle of the present invention is: concavo-convex meeting point, two places is the ingenious design part of L shell body, concavo-convex meeting point, two places is designed to the concave-convex of consistent size respectively.Like this, when agreeing with relatively, last lower house can effectively guarantee its seal.The heat radiation convex is adopted on L type main casing surface, because convex increases the surface area of casing and is twice, this just can make the surface radiating effect of casing also increase one times.Circuit board can directly be contained in the L shell body of bottom by chute.Simultaneously, first side cover and second side cover also can be fixed with screw and bottom L shell body earlier.Like this, the half-bridge circuit high power valve just can be installed in a side of housing very easily, the pfc circuit high power valve also can be contained in and half-bridge circuit high power valve distance first side cover far away, and this just plays the highly effective high-power RF that prevents and disturbs and improve the effect of the Electro Magnetic Compatibility of electric ballast.Under half state that opens wide, the great-power electronic ballast internal circuit board must be installed, debugging, check, it is very convenient that adjustment process becomes.After whole debugging was qualified, top L shell body was fixed with screw at two side cover plates on the cover.Promptly finish whole installations of great-power electronic ballast.Can carry out when needing also only need to open top L shell body when great-power electronic ballast keeped in repair later on.
The invention has the beneficial effects as follows: 1, be convenient to Installation and Debugging: top L shell body can be opened easily, circuit board can directly be inserted in the circuit board insertion groove of bottom L shell body, under the state that opens wide for the debugging of components and parts, installation, maintenance bring great convenience, particularly when unlimited high power valve and casing radiator to be connected and fixed installation more convenient.2, die sinking is simple: because main casing is assembled by the anti-phase butt joint of two identical L shell bodies, get final product so only need do half shape of original mould.3, L shell body concave-convex type agrees with and has reached anti-rainwater, dustproof requirement fully.4, L shell body on maintenance the time is removed and just can be removed easily behind the top screw of two end cover plate.Be convenient to open direct maintenance or adjust inner components and parts or circuit parameter.This is that other various forms all are difficult to accomplish at present.The half-bridge circuit high power valve can very easily be installed in a side of housing, keeps enough distances with the pfc circuit high power valve, can highly effectively prevent that high-power RF from disturbing.Improve the Electro Magnetic Compatibility of electric ballast.5, the surface portion of L shell body is made the convex of heat radiation, and surface area is increased.Radiating effect is more obvious.

Embodiment
As shown in Figure 1, the present invention includes: bottom L shell body 1, top L shell body 2, first side cover 3, second side cover 4, concavo-convex meeting point 5, two places, two the identical bottom of shape and size L shell bodies 1 form L type main casing with top L shell body 2 by concavo-convex meeting point, two places 5 relative agreeing with, two end sections of L type main casing are square, first side cover 3 and second side cover 4 are fixed on by screw on two end sections of L type main casing, the concave-convex that concavo-convex meeting point 5, described two places is nominal dimension unanimities.
Concavo-convex meeting point 5, described two places, its spill is chosen plus tolerance, and convex is chosen negative common difference, makes to keep three grades of interference fit when agreeing with.
The center size of concavo-convex meeting point 5, described two places must be consistent.
