Abstract

PURPOSE:To mount a shield structure with an automatic winding machine by providing another winding between the windings of a transformer having a plurality of windings, grounding the one end of the windings and opening the other ends thereof. CONSTITUTION:In a shield structure, a shield winding 6 is wound between the primary winding 1 and the secondary winding 2, with the one end of shield winding 6 grounded and the other end opened. The shield winding 6 mush be wound with less number of turnings and without any gap using a thick lead wire from the point of view of the property of inducing a voltage on such coil. Otherwise, a number of turns is reduced by forming a shield winding 6 using two lead wires wound in parallel. In this case, gap is eliminated in actual. Thereby, windings can be formed with the automatic winding machine including the shield structure and accordingly an economical transformer can be realized while keeping the desired shield effect.

Description

【発明の詳細な説明】 〔発明の利用分野〕 本発明は、トランスのシールド構造に関するものである
。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a shield structure for a transformer.

〔発明の背景〕[Background of the invention]

伝送トランスや電源トランスにおいでは、−次側に印加
される縦電圧成分を二次側に伝送したくないときに、そ
の巻線間にシールドを設け、これを接地している。In a transmission transformer or a power transformer, when it is not desired to transmit the vertical voltage component applied to the negative side to the secondary side, a shield is provided between the windings and this is grounded.

に巻線を巻いた様子を示す。Ru. Figure 2 is a cross-sectional view of the winding of the transformer shown in Figure 1, with the bobbin 5
The figure shows how the wire is wound.

きず、手作業となり、高価になる。In the conventional shield structure, a metal foil 3 is wound between the windings, and a lead wire is attached to the metal foil 3. Since this involves winding metal foil, which is handled differently than the wire, an automatic winding machine cannot be used when manufacturing this, and the winding is done manually, which is expensive.

〔発明の目的〕[Purpose of the invention]

本発明の目的は、シールド構造を改善し、シールド構造

ランスを実現した。In order to achieve the above object, the present invention provides a shielding structure in which the metal foil is replaced with a wire that can be handled by an automatic winding machine, thereby realizing an economical transformer while maintaining the desired shielding effect.

〔発明の実施例〕[Embodiments of the invention]

本発明の一実施例を第３図および第４図に示す。 An embodiment of the invention is shown in FIGS. 3 and 4.

■は一次巻線、２は二次巻線、４はコア、５はボビン、
６はシールド巻線である。■ is the primary winding, 2 is the secondary winding, 4 is the core, 5 is the bobbin,
6 is a shield winding.

実施例におけるシールド構造は、−次巻線１と二次巻線
２の間にシールド巻、１６を巻き込み、前記シールド巻
線６の一端を接地し、他端を開放とするものである。The shield structure in the embodiment is such that a shield winding 16 is wound between the negative winding 1 and the secondary winding 2, one end of the shield winding 6 is grounded, and the other end is open.

シールド巻′ａ６は、そのコイルに電圧を誘起する性質
上、巻数を少なくし、かつ、太目の線材を使用し、すき
間をあけないように巻く必要がある。Since the shield winding 'a6 induces a voltage in the coil, it is necessary to reduce the number of turns, use a thick wire material, and wind it without leaving any gaps.

線６とすることにより、巻数を少なくした例を第５図に
示す。なお、第５図は２本並列巻きを明らかにするため

間をあけないように巻く。As another embodiment, FIG. 5 shows an example in which the number of turns is reduced by using two wires wound in parallel as the shield winding 6. In FIG. 5, the shield windings are spaced apart in order to make it clear that the shield windings are wound in parallel, but in reality, the shield windings are wound so that there is no space between them.
