Description
Technical field
The present invention relates to inductive type ballast or transformer, relate in particular to the clad structure of E cross magnetic core array inductive type ballast or transformer.
Background technology
The existing market illumination is divided into two big types with ballast: inductance type and electronic type.Electronic ballast is because useful life is short and high-frequency harmonic disturbs problems such as stronger, thus market adopt mostly remain Inductive ballast.Inductive ballast is divided into two types basically according to the magnetic core array structure: E font and C font.C font ballast is because problem such as processing technology complicacy and price be more expensive, and at present domestic is the mainstream product in the market with E font ballast still.
In the prior art, Inductive ballast and high-power transformer generally adopt irony base or totally-enclosed case to add the fixing clad structure of tightening up a screw.The irony base adds the fixing clad structure of tightening up a screw does not have shielding action for electromagnetic field; Totally-enclosed case adds the fixing clad structure of tightening up a screw and has shielding action preferably for electromagnetic field, but volume is big, Heavy Weight, and consumptive material is many.The inductance type miniature transformer then generally adopts the clad structure of non-enclosed type case, mainly coats the end face of E font iron core and yi word pattern yoke with iron sheet, and this clad structure has little, the lightweight advantage of volume, but poor for the shielding action of electromagnetic field.Application number CN201120240089.0; The prior art that name is called " the modified model clad structure of Inductive ballast or transformer " is the Inductive ballast as shown in Figure 1 or the modified model clad structure of transformer; Tongue 26 on the upper shell buckle 25 inserts in the catching groove 29 of lower house buckle 27, and the tail end 28 of tongue 26 bends, and is closely buckled in the outer surface of lower house panel 30; This kind structure the phenomenon that gets loose occurs after long-time the use, influence the performance of ballast; Between upper shell buckle 25, be stamped barricade 31, heat radiation when being unfavorable for the work of Inductive ballast or transformer, long-time continuously the use has potential safety hazard.
Summary of the invention
The applicant provides the modified model clad structure of another kind of Inductive ballast or transformer to the above-mentioned shortcoming of existing Inductive ballast or transformer clad structure, and its coating is firm, volume is little, good heat dissipation effect.
Technical scheme of the present invention is following:
The modified model clad structure of Inductive ballast or transformer comprises upper shell and lower house, and upper shell comprises top panel, and the last latch of fixed magnetic core body is arranged on the top panel; The peripheral clearance of top panel is provided with the last buckle of bending downward vertically, and the top of last buckle and sidepiece have tongue respectively and go up bending; Lower house comprises lower panel, and the following latch of fixed magnetic core body is arranged on the lower panel; The peripheral clearance of lower panel is provided with the upwards lower pinch plate of vertical bending, and the sidepiece of lower pinch plate has bending down; The installed part that has Inductive ballast or transformer on the lower panel, said installed part for lower panel be the earhole plate of one and the buckle of trough of belt mouth, locating button is arranged at the bottom of notch; It is characterized in that: have the tongue hole on the lower pinch plate; The height of the said upper surface of bending down on the lower pinch plate is between the upper surface and lower surface in tongue hole; Lower pinch plate outwards is bent into horizontal level from the upper end surface of bending down respectively; Make the part in said tongue hole outwards be bent into horizontal level thereupon; Tongue on the last buckle inserts the tongue hole of said horizontal level respectively, and the tail end of tongue outwards bends, and is closely buckled in the outside bending end of lower pinch plate;
Further technical scheme is following:
The said quantity that goes up tongue on the buckle is 2 or 3;
Said tongue is square;
The quantity of tongue is identical on the quantity in the tongue hole on the said lower pinch plate and the last buckle;
The tongue hole is square on the said lower pinch plate.
Technique effect of the present invention is:
1, match in 2 or 3 tongue holes that are provided with on the buckle on the upper shell on the lower pinch plate of 2 or 3 tongues and lower house, through tongue and lower pinch plate are carried out bending, guaranteed the firmness that upper shell and lower house coat;
2, be the gap between the buckle and between the lower pinch plate on the lower panel of lower house on the top panel of upper shell, help the heat radiation in working order time of Inductive ballast or transformer.
