Embodiment
To shown in Figure 5, is an embodiment of drawer type transformer of the present utility model as Fig. 1, can be used for LED display, LED lamp bar etc., can certainly be applied to other occasions.
This drawer type transformer comprises drain pan 10, loam cake 20, circuit board etc.This circuit board is provided with current rectifying and wave filtering circuit, control circuit, transforming circuit etc., and these circuit can adopt existing various circuit to realize.
As shown in the figure, this drain pan 10 roughly is shaped as frame, and its top is provided with opening, so that the putting into of circuit board.In the present embodiment, this drain pan 10 adopts amalgamation drain pan 10, for example, adopts sheet material to bend out base plate, side plate, and then base plate and side plate amalgamation are fixed, thereby form whole shaped as frame drain pan 10.
The flanging 11 that bends inwards out at the edge of the opening of this drain pan 10, this loam cake 20 is fixedly mounted on this flanging 11 by slip snap device and retaining mechanism.As shown in the figure, this flanging 11 is provided with in the both sides of the edge of opening, and is understandable, the also lateral edges setting therein or also be provided with at other edges simultaneously of this flanging 11.
Further, owing to there are the heating components and parts on the circuit board, on the sidewall of this drain pan 10 and/or base plate, be provided with a plurality of heat radiation through holes 12, so that the distributing of the hot-air in the drain pan 10.In addition,, be provided with line three-way hole 13, and be somebody's turn to do line three-way hole 13 and can be arranged on position near loam cake 20 at least one sidewall of drain pan 10 for the ease of drawing of the lead of circuit board, thereby more near circuit board, so that outlet.
This loam cake 20 is installed on the flanging 11 by slip snap device pre-determined bit, and in the present embodiment, this slip snap device comprises button hole 14 that is arranged on the flanging 11 and the cramps 21 that are provided with in loam cake 20 inboards.As shown in the figure, this cramp 21 forms by the mode of punching press, has certain distance between this cramp 21 and loam cake 20 main bodys, thereby after cramp 21 inserts button hole 14, can be buckled in the inboard of flanging 11, forms pre-determined bit.
Understandable, this slip snap device can also adopt other form, for example button hole is arranged on to cover, and corresponding cramp washes off on flanging, cramp can be inserted button hole equally, and make cramp be located in the outside of loam cake, forms pre-determined bit.
After loam cake 20 pre-determined bit are installed to drain pan 10, by retaining mechanism loam cake 20 and flanging 11 are being locked, thereby loam cake 20 is being fixedly mounted on the drain pan 10.In the present embodiment, this retaining mechanism is included in the screwed hole 15 that is provided with on the flanging 11, the through hole 22 and the trip bolt that are provided with on loam cake 20.This screwed hole 15 is corresponding with the position of through hole 22, and passes through hole 22 by this trip bolt, screws in screwed hole 15, thus with loam cake 20 fixing and lockings on flanging 11.
Certainly, this trip bolt can also adopt bolt or other securing members.This through hole 22 also can adopt counter sink etc., avoids the exposing of head of screw, makes that the surface of loam cake 20 is more smooth.
Further, the both sides of this loam cake 20 can also be provided with mounting ear 23, thereby whole transformer can be fixedly installed to suitable position.
During assembling, earlier circuit board is fixedly mounted on the inner surface of loam cake 20 by modes such as screw or buckles; Then circuit board is aimed at the opening of drain pan 10, put in the drain pan 10, and cramp 21 is inserted in the button hole 14; Promote loam cake 20 then and slide, make cramp 21 buttons establish the edge of button hole 14, make and outwards to extract loam cake 20, form pre-determined bit; Use trip bolt to pass through the through hole 22 of loam cake 20 then, screw in the screwed hole 15 of flanging 11, thereby, finish assembling loam cake 20 and drain pan 10 lockings.
Owing in the assembling process, circuit board need not be fixed on the drain pan 10, thereby avoid defectives such as drain pan 10 sidewalls obstruction lock screw, easy clashing and breaking circuit board in the prior art, have advantages such as easy to assembly, safe.
Understandable, the quantity of this slip snap device, retaining mechanism, position etc. can be designed as required, are not limited to above-mentioned execution mode.Above embodiment has only expressed preferred implementation of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model; Therefore, all equivalents and modifications of being done with the utility model claim scope all should belong to the covering scope of the utility model claim.
