(execution mode 1)
With Fig. 1 to Fig. 4 embodiments of the present invention 1 are described below.Fig. 1 is the outside drawing of formation as 1 group of U font iron core 1 of the iron core of an example of core.Fig. 2 is the key diagram that is used to illustrate the formation in gap unshakable in one's determination, described iron core comprises: part of the V-shape bending part 3A of the banded sheet 2 of U font iron core 1, ubi infra, this band shape sheet 2, the not bending of banded sheet 2 (part beyond the V-shape bending part 3A is called not bending part 3B below) and bobbin 4.Fig. 3 is the outside drawing of banded sheet 2.Fig. 4 is the outside drawing that the state of having assembled banded sheet 2 and U font unshakable in one's determination 1 and bobbin 4 is shown.
The following describes the formation of interferric space in the present embodiment 1.As depicted in figs. 1 and 2, for example, a pair of U font iron core 1 morphosis to face with each other.And, as shown in Figures 2 and 3, be formed with V-shape bending part 3A near the central authorities by the formed banded sheet 2 of insulating material.And as described below, in case clamp V-shape bending part 3A 1 unshakable in one's determination of U font, the global shape of banded sheet 2 just is approximate T font.In addition, as shown in Figure 2, the degree of depth of the V-shape bending part 3A of banded sheet 2 almost equates substantially with the thickness of U font iron core 1.In addition, this V-shape bending part 3A equate with sectional area with the area of the section part in opposite directions of U font iron core 1 with U font iron core 1 or more than be advisable.What use as banded sheet 2 in addition, is to be non magnetic aspect the magnetic and material that have insulating properties aspect electric.
Be that the assembling of transformer describes to having a routine electric equipment unshakable in one's determination below.
During the assembling transformer, for instance, as shown in Figure 2,, prepare the bobbin 4 of coiling coiling usefulness in order to form coil.Among Fig. 2 bobbin 4 is inserted the U font iron core 1 that is positioned at the below, banded sheet 2 also inserts together.At this moment, V-shape bending part 3A is configured to be in the profile position of U font iron core 1.Make the contoured surface part of the not bending part 3B of banded sheet 2 along the U font iron core 1 that is positioned at the below.And, the U font unshakable in one's determination 1 of top is inserted the V-shape bending part 3A that the bobbin 4 interior feasible butted parts that are in the U font iron core 1 of position, above and below are clamped banded sheet 2.
After this, as shown in Figure 4, under the state that the V-shape bending part 3A (not shown) of banded sheet 2 is clamped by 1 pair of U font iron core 1, fix 1 pair of U font iron core 1 by 2 legs 6 being combined by 2 bolts 7.And, form coil by bobbin 4 is wound the line, and constitute transformer.
In addition, what illustrate here is that 1 pair of U font unshakable in one's determination 1 and banded sheet 2 are inserted the example of bobbins 4, forms coil but also can manage bobbin 4 wound the line, and again U font unshakable in one's determination 1 and banded sheet 2 is inserted coils.
In addition, the length of banded sheet 2 when being clamped by U font iron core 1, is longer than bobbin 4 and coil, is advisable for recognizing banded sheet 2 this length from the outside with the total length of bending part 3B not.
Now the transformer that constitutes is as mentioned above illustrated its effect.
As shown in Figure 2, assemble under the situation of 1 pair of U font iron core 1, bobbin 4 and banded sheet 2, the V-shape bending part 3A of the formed banded sheet 2 of the wherein a part of bending of OBL banded sheet 2 is sandwiched between 1 pair of U font iron core 1.Therefore, needn't carry out banded sheet 2 is mounted on this operation on the U font iron core 1, can be fixed in naturally between 1 pair of U font iron core 1.Have, banded sheet 2 is present in the inside of bobbin 4 again.Therefore, even if the V-shape bending part 3A of banded sheet 2 staggers with respect to the butted part of U font iron core 1, also because the interior shape of bobbin 4 is a tubular, so can keep to avoid banded sheet 2 to stagger by bobbin 4 with respect to the butted part of U font iron core 1.In addition, as shown in Figure 4, when assembling 1 pair of U font iron core 1, bobbin 4 and banded sheet 2, the not bending part 3B that forms banded sheet 2 exposes the structure in bobbin 4 outsides.Here, play the coil terminals 5 of its lead-out wire effect for be exposed to outside coil (not shown) in the middle of bobbin 4, in case add the mechanical force from the outside, both contact just might to make coil terminals 5 and U font unshakable in one's determination 1.But, utilize the not bending part 3B of banded sheet 2 to be positioned at U font unshakable in one's determination 1 and coil terminals 5 formation between the two, just banded sheet 2 can make coil terminals 5 and U font iron core 1 electric insulation between the two as present embodiment 1.
Again as shown in Figure 4, because bobbin 4 outsides have the banded sheet that exposes 2 to exist, thereby thereby when installing to transformer group in the product can with the banded sheet 2 of visual confirmation wherein the V-shape bending part 3A of a part whether correctly insert 1 unshakable in one's determination of U font and form the gap 1 unshakable in one's determination of U font.
