が形成される。``Problems to be solved by the invention'' In the small transformer as described above, after the first coil is wound around the iron core or bobbin, an insulating tape is wrapped around the first coil, and then the first coil is wrapped around the first coil. A second coil is wound around the coil, and electrical insulation is provided between each coil. However, since the above-mentioned insulating tape is wound by an automatic machine during the automatic coil winding process, it is often wound at an angle to the central axis of the coil winding, and in this case, the insulating tape is wound on top of it. During the winding process of the second coil, the wire slides on the insulating tape according to the inclination, so the winding of the second coil is biased to one side, forming a part with more windings and a part with less winding.

One end of the first coil pulled out from the final stage winding layer and the second coil wound overlappingly on the final stage winding layer.
A common end is provided that connects one end of the coil drawn out from the first winding layer, and this common end, the other end of the first coil, and the other end of the second coil are connected to separate terminals. We propose a compact transformer characterized by a fixed structure.

る。 According to this invention, since the electrical insulation between each coil can be removed, winding the second coil directly around the first coil prevents the coils from being biased, and also improves the electrical insulation. This is advantageous in terms of production efficiency because the step of wrapping the object can be omitted, and furthermore, since no area is required to house the electrical insulator, the transformer form can be made smaller.

して公知である。 FIG. 1 is an electrical circuit diagram of a small transformer 1 equipped with a primary coil 2 having coil ends 2a and 2b and a secondary coil 3 having coil ends 3a and 3b, and FIG. 2 is a mechanical diagram of the transformer 1. FIG. Such a small transformer 1 is known as a trigger transformer incorporated in a flash discharge light emitting device for photography.

通端子１ｃとなつている。 In this small transformer 1, an insulating tape 5 is provided between a primary coil 2 and a secondary coil 3 that are wound around a flanged bobbin 4, and an iron core 6 is inserted into the cylindrical part of the bobbin 4. has been done. Although not shown, the coil ends 2a, 2b of the primary coil 2 and the coil ends 3a, 3b of the secondary coil 3 are fixed to terminal pins implanted in the bobbin collar.
b and 3b are connected as shown in FIG. 1 to form one common terminal 1c.

Then, the potential difference between the winding layers located on the inner and outer surfaces of the insulating tape 5 becomes almost the same, so there is no risk of leakage between the winding layers, and in particular, there is no need to provide the insulating tape 5 between the coils.

絶縁が必要である。 However, in this type of transformer 1, the number of windings in the secondary coil 3 is large, and the highest potential difference appears between the winding start part and the winding end part. If the winding becomes disordered, such as protruding near the
The potential difference between the coils becomes extremely large, easily causing a leakage accident, and electrical insulation using the above-mentioned insulating tape 5 or the like is required.

A is formed, and then a second layer 30b is formed on the first layer 30a by winding from the side of the collar 4b to the side of the collar 4a, and a third layer 30c is similarly wound on the second layer 30b.
A fourth layer 30d is formed on the third layer 30c, an n-th layer 30n is formed on the n-1th layer 30n-1, and the winding end 3F is located at one end of the outermost layer. be.

0a is joined to the outermost layer 30n of the secondary coil 3. In addition, in this embodiment, 2 is used as the primary coil 2.
Since the coil is formed in layers, the winding end 2F is located on one side of the second layer 20b, but the number of windings of the primary coil 2 may be arbitrary, such as forming one layer or less than one layer depending on the winding. Further, the coil ends 2a, 2b, 3a, 3b pulled out from the winding start 2S, 3S and the winding end 2F, 3F of the coil are fixed to the terminal pins as described above.
