Abstract
The utility model discloses a full-closed safety transformer comprising a coil (7), an outer shell and two parallel insertion pieces (1), wherein the head end and the tail end of a winding (8) of the coil (7) are welded to the lower ends of the two insertion pieces (1) respectively. The full-closed safety transformer further comprises an installation block (2) and a stop dog (3), the two insertion pieces (1) and the installation block (2) are integrated in an injection molding mode, the upper end and the lower end of each insertion piece (1) extend out of the installation block (2), the lower end of the installation block (2) is in inserted connection with the upper end of the stop dog (3) in a matched mode, and one side face of the stop dog (3) is provided with two U-shaped grooves (4) used for containing the parts, extending out of the installation block (2), of the lower ends of the insertion pieces (1). According to the full-closed safety transformer, deviation in the distance between the top ends of the two insertion pieces (1) is small, and the welding portions of the winding (8) of the coil (7) and the insertion pieces (1) are prevented from being impacted and damaged by filled liquid when injection molding is carried out.
Description
Technical field
The utility model relates to a kind of electric elements, is specifically a kind of fully-enclosed safe transformer.
Background technology
Fully-enclosed safe transformer comprises coil, shell and two inserted sheets, coil consists of bobbin and the coiling being coiled on bobbin, respectively with two, the two ends end to end inserted sheet of coiling is welded and fixed, and the middle and lower part of coil and two inserted sheets is all positioned at shell, and shell is stretched out on the top of two inserted sheets.Between this transformer and other electrical equipment, without wire, be connected, give after two inserted sheet indirect currents of this transformer, the coil of transformer produces alternating magnetic field, and alternating magnetic field directly acts on other electrical equipment, impels electrical equipment action.Owing to being connected without wire between this transformer and other electrical equipment, belong to closed, safer, therefore named fully-enclosed safe transformer.
This fully-enclosed safe transformer in manufacturing process, first by the head and the tail two ends of the coiling of coil respectively with the bottom welding of two inserted sheets, and coil and inserted sheet are placed in to the die cavity of mould, last injection mo(u)lding shell.In injection moulding process, coiling lacks an overfill protection with the weld part of inserted sheet, during injection moulding easily by fluid injection impact failure.And because shell is integral molded plastic moulding, volume is relatively large, once cooling after-contraction amplitude is also larger, can cause like this distance dimensional discrepancy between the top of two inserted sheets very large.
Utility model content
The technical problems to be solved in the utility model is, provide a kind of can guarantee that two range deviations between inserted sheet top are little and can avoid injection moulding time coil-winding and inserted sheet weld part by the fully-enclosed safe transformer of fluid injection impact failure.
Technical solution of the present utility model is, a kind of fully-enclosed safe transformer with following structure is provided, it comprises the inserted sheet that coil, shell and two are parallel to each other, weld with the lower end of two inserted sheets respectively at the head and the tail two ends of the coiling of coil, it also comprises a mounting blocks and a block, two inserted sheets and mounting blocks are injected into upper end, the lower end of one and two inserted sheets and all stretch out mounting blocks, peg graft and coordinate with block upper end in the lower end of mounting blocks, a side of block is provided with two and stretches out the U-lag of the part of mounting blocks for accommodating inserted sheet lower end.
Adopt after above structure, the utility model fully-enclosed safe transformer compared with prior art, has the following advantages:
The manufacture process of this transformer is: by inserted sheet lower end and coiling welding, and mounting blocks is inserted on baffle plate, by the end face of baffle belt U-lag and coil against, again coil, mounting blocks and baffle plate are put into mold cavity, like this, the U-shaped face of mounting blocks base plate, U-lag, coil have just formed one by face of baffle plate and the bottom surface of die cavity and have blocked the chamber that fluid injection is impacted, and the weld part of inserted sheet lower end and coiling is just contained in this chamber, finally injection mo(u)lding shell.
From analyzing above, first, the shell of this transformer is not integral molded plastic moulding, but first mounting blocks and inserted sheet are injected into one, together with finally mounting blocks being injection-moulded in shell, like this, the mounting blocks volume of fixing inserted sheet is less with respect to the whole shell of prior art, therefore the amplitude of cooling after-contraction deformation is also very little, the distance dimensional discrepancy that makes to be fixed on two inserted sheet tops on mounting blocks is little, more accurate; During also due to injection moulding, the weld part of inserted sheet lower end and coiling in U-lag, and is not impacted by fluid injection by accommodating protection, is difficult for destroyed.
As improvement, mounting blocks bottom surface is provided with two projections, and the end face of block is provided with two pits, and each projection inserts in a corresponding pit, and like this, mounting blocks and block grafting coordinate convenient and strength-saving reliable.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fully-enclosed safe transformer of the present utility model as shown in Figure 1, Figure 2, Figure 3 shows, it comprises inserted sheet that coil 7, shell, two be parallel to each other 1, mounting blocks 2 and a block 3.Weld with the lower end of two inserted sheets 1 respectively at the head and the tail two ends of the coiling 8 of coil 7.Two inserted sheets 1 all stretch out mounting blocks 2 with upper end, lower end that mounting blocks 2 is injected into one and two inserted sheets 1.Peg graft and coordinate with block 3 upper ends in the lower end of mounting blocks 2, mounting blocks 2 bottom surfaces are provided with two projections 5, and the end face of block 3 is provided with two pits 6, and each projection 5 inserts in a corresponding pit 6.A side of block 3 is provided with two U-lags 4.The part of stretching out mounting blocks 2 of each inserted sheet 1 lower end is positioned at U-lag 4.
