Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an I-lance having a winding plate having a flexible lead wire portion.

When winding transformer windings around an iron core, it is necessary to ensure insulation between each winding and draw out taps, especially when winding a large number of various windings with a small number of turns. In the case of winding, a lot of work is required, such as wrapping insulating paper between the layers of each winding, winding, tap drawing, and wire lJ' + It was an axe.

The present invention makes it possible to easily and speed up the transformer assembly work by forming various wires using a winding plate having a wire part and a leader wire part as a body, and its structure is described below. will be explained with reference to illustrated embodiments.

1M'3 and FIG. 2 show the curve 1 of the present invention,
] is a glass board 2 with a winding 3 and a leader wire 4, and the winding 3 and leader wire 4 are formed on the board 2 using a printed circuit board, a thin foil plate, or a linear shape. A conductor is pasted and, if necessary, a coating 5 is provided integrally with the substrate or buried. This will be explained below using an example. The plastic substrate in the winding portion 6 on which the winding wire 3 is printed is formed to be thick as shown in the second figure, and the core hole 7 is provided in the central rigid part thereof, and the plastic substrate on which the leader wire 4 is printed is formed to have a thick wall as shown in the second figure. The substrate portion is made thin to form a flexible portion 8 having flexibility, and the tip of the flexible portion 8 draws out a terminal 9 from the end face of the plus deck board to form a terminal portion]-◯. In order to stably connect the terminals 9 to the terminal portion 10, the end portion of the glass substrate is formed thick as shown in the second figure. In addition, although the example in which the number of turns of 30 wires in the winding part 6 is one turn is shown in the first case, if necessary, various numbers of turns may be printed around the core hole 7, and , winding section 6 and terminal section 10
Instead of forming the plus deck board portion thickly as shown in the second figure, it may be formed flat if necessary.

FIG. 3 shows an embodiment of a transformer using the printed winding plate 1 as described above, in which one iron core hole 7 of the printed winding plate l is attached to the center leg of the iron core 2, and The transformer is assembled by fitting the bobbin 14 around which the regular winding 13 is wound. Note that the pin 5 is a pin protruding from the bobbin 14. The winding wound on this bobbin 14]-3 can be either a single winding or a composite winding such as primary, secondary, etc., and can be used with a relatively large number of turns. The work of winding a small amount of winding around the iron core involves simply using a printed winding board l on which the winding is printed and fitting it inside the button and core, and the lead wire of the winding is also integrated. Since it is printed, there is no need to perform tap-drawing work,
The transformer can be assembled extremely easily and quickly.

The above-mentioned printed winding board 1 does not simply print one type of winding wire, but also prints two or more types of winding wires on one printed winding board and distributes them according to the number of wires. It is also possible to provide a large number of terminals in the terminal section, and since the space on the iron core is small for the printed winding board, it is possible to install one printed winding board as in the embodiment shown in the third figure. 1, which has a large number of windings as shown in Figure 4.5.6 by attaching multiple printed winding plates to a small iron core.
It is also possible to construct a lance.

Figure 4 is an exploded view of each part of the lance shown in Figure 5, and the same parts as Figure 3 are shown.

The embodiment shown in FIGS. 4 and 5 is suitable for a transformer for a discharge lamp lighting device as shown in FIG.
The next winding P and the second winding S are respectively wound around the bobbin 14.
has. The printed wiring board 20 has windings 21, 22, 23 printed on the winding part 6, and the printed lead wire of each winding passes through the flexible part 8 and is connected to the terminal 9 for each winding in the terminal part 10. and the other printed wiring board 3
0 has a printed winding g31 on the winding part 6, and a terminal 9 is attached to the terminal part 1o at the tip of the flexible part 8 on which the leader line is printed.
has. These printed winding plates 20 and 30 are arranged on both sides of both bobbins 14 for the primary winding p and secondary winding S as shown in the fourth figure, and each iron core hole 7 of both printed winding plates 2o and 3o is Then, the central leg of each core half 12, 12 is inserted into each of the core holes 7 of both the primary and secondary windings p and s to assemble the transformer as shown in Figure 5. In the transformer of this embodiment, in addition to both the primary and secondary windings PXs, windings 2], 22.23.3
It has 4 types of windings of 1, but the printed winding board 20.30
The transformer is assembled by simply attaching both the primary and secondary wires to the iron core along with the wires p and s, making the work extremely easy and quick.

The above embodiment describes an example in which the winding lead wire is printed on a Plus Deck board.However, the winding wire and lead wire are printed on a Plus Deck or other insulating board, and the winding wire and lead wire are printed on a Plus Deck board or other insulating board. It may be installed by pasting a conductor such as a wire, and if necessary, it may be provided with an insulation/protection coating, or it may be installed by burying a conductor as described in 041. It's something that can't be helped.

As described in 2 below, the present invention enables even a large number of windings with a small number of windings to be formed on a winding plate.
By attaching 1 to a small number of windings R't, not only can 7 be obtained, but also it can be molded into a uniformly sized component that is easy to handle, making it possible to downsize the transformer.In addition, the lead wire can be integrated with the winding. Since the winding Iiyama is provided at the winding Iiyama, there is no need to pull out the tamp, and since the lead wire part is an IF flexible part 8, the connection work of the terminals 9 is facilitated. Since the terminals are arranged in the same order as 10, each terminal can be connected without confusion. Therefore, the assembly work of the transformer is different from the conventional winding work.
Interlayer tape work, tap drawing work, soldering work, etc. are all unnecessary, making assembly easy and quick, and reducing costs.
