〔分野の概要〕
本発明はトランス、又はコイルを構成するコイルボビン
の構造に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Overview of the Field] The present invention relates to the structure of a coil bobbin constituting a transformer or a coil.
従来、空隙のない磁心に使用するコイルボビンは、図−

対位置の端の部分に銅線が来ると、歯車には外部からの
力を強く加えないと巻線が出来なくなること、又コイル
ボビンは銅線に引っ張られるためコイルボビンの内径と
磁心は一様に接触せず、滑らかに回転出来ず非常に巻き
にくいと云う欠点があった。Conventionally, coil bobbins used for magnetic cores with no air gaps are shown in Figure-
As shown in 6, winding is carried out using a two-split coil bobbin with a gear 3 that meshes with an external drive gear 4 for rotating the coil bobbin during winding, provided on the outer surface of the collar of the coil bobbin. However, when winding, if the copper wire comes to the end opposite to the gear, winding will not be possible unless a strong external force is applied to the gear, and the coil bobbin will not touch the copper wire. Due to the tension, the inner diameter of the coil bobbin and the magnetic core do not come into uniform contact with each other, making it impossible to rotate smoothly and making it extremely difficult to wind.

磁心と組合せたコイルボビンをコイル取り付け基台に樹
脂を用い接着し、トランス・コイルに完成する。In order to eliminate the above-mentioned drawbacks, the present invention has a structure in which the gear of the coil bobbin is attached to the middle flange of the central partition part of the coil bobbin, and the inner flange to which the gear is attached is driven by an external drive gear. It is something. Therefore, even rotation is applied to the coil bobbin, making it easier to wind the wire uniformly. In the case of the coil bobbin having the structure according to the present invention, when attaching the coil bobbin to the board, a separate coil mounting base is prepared as in the conventional case.
The coil bobbin combined with the magnetic core is glued to the coil mounting base using resin to complete the transformer coil.

でインダクタンスを大きくし得ると云う利点を持つ。In addition, since the coil bobbin according to the present invention has a gear on the middle flange, there is no need for the conventional flange provided on the outside of the end face of the coil, and the winding portion of the coil bobbin is widened, making it possible to increase the inductance with the same dimensions. It has the advantage of

ンとするものである。On the other hand, another object of the present invention is to provide a two-split coil bobbin with an external drive gear when winding the coil bobbin.
By adopting a structure in which a gear is attached to the middle flange of the coil bobbin, a protrusion for attaching a pin terminal is provided on the outer surface of both sides of the coil flange, and by attaching a pin terminal for attaching a board to the protrusion, the coil bobbin can be directly attached to the two-split coil bobbin. This is a coil bobbin with a structure that allows pin terminals to be attached and mounted on a board.

ずると云う問題があった。FIG. 6 is a diagram showing winding using a coil bobbin of a conventional structure. The magnetic core 1 is a square-shaped magnetic core with no gaps in the magnetic path, and the coil bobbin 2 is divided into two parts. A gear 3 is attached to the outside of the coil bobbin. The gear 3 rotates the coil bobbin and winds it. It has a structure that meshes with an external drive gear 4 that drives the line. In a conventional gear, a gear is attached to the outer surface of a coil bobbin as shown in Figure 6, and the winding 5 is made by winding a copper wire 51 onto the coil bobbin, but the winding copper wire is located far away from the gear being driven. However, it is important to note that winding the copper wire requires force, and that if the bare copper wire 51 that does not sag is pulled strongly, the contact between the inner diameter of the coil bobbin and the magnetic core becomes strong, which causes various troubles when winding the copper wire into the coil bobbin. There was a problem that occurred.

イルボビンの中鍔６に歯車３１を設け、外部駆動歯車４
によりコイルボビンを駆動する構造としである。Embodiment 1 FIG. 1 is a diagram showing an embodiment of the present invention, in which a gear 31 is provided on the middle flange 6 of a coil bobbin divided into two, and an external drive gear 4 is provided.
The structure is such that the coil bobbin is driven by the coil bobbin.

イルボビンのほぼ中央部に鍔を設けて使用するもので、
此の中鍔を利用し、中鍔に歯車を設けるものである。Common mode choke coils used in circuits that suppress electromagnetic noise require two windings with approximately the same number of turns to be wound symmetrically around a coil bobbin with a magnetic core that has a magnetic path without air gaps. A middle collar is installed in the center of each coil bobbin to divide the winding into two equal parts. Also, in a transformer, when the voltage difference between the primary and secondary windings is large, the coil bobbin It is used with a tsuba located almost in the center.
This inner tsuba is used and a gear is installed on the inner tsuba.

れる。FIG. 2 shows the shape of a coil bobbin according to an embodiment of the present invention, and 7 shows a connecting part of the two-part coil bobbin, and the abutting surfaces of the two-part coil bobbin are stepped,
Alternatively, an interlocking mechanism may be provided, and the joint may be bonded using resin. With this structure, the gears of the conventional structure provided on the flanges at both ends are unnecessary, so the winding width of the coil bobbin becomes correspondingly wider, and the inductance can be increased with the same dimensions.

歯車部分への力は図−６の従来構造の場合に比べて半分
となり、巻線の作業は容易となる。In the coil bobbin, the gear 31 attached around the inner rim is driven by the external drive gear 4, so the force applied to the gear by the winding 51 is halved compared to the conventional structure shown in Figure 6, and the winding Line work becomes easier.

端子付きコイルボビンを構成出来る。The coil bobbin of the present invention has a structure in which a gear is provided on the middle flange of the two-split coil bobbin, and the gear is rotated via an external drive gear to wind the coil. In addition to creating a coil bobbin that is easy to handle, when the dimensions are the same, it is possible to wind more wires and increase inductance compared to the conventional two-piece coil bobbin in which the gear is installed on the outside of the flanges at both ends. By attaching the gear that drives the coil bobbin, a protrusion can be installed on the outside of the flange at both ends of the coil bobbin, and a pin terminal can be implanted, eliminating the need for a coil mounting base for board mounting, and making it possible to install a coil bobbin with a small number of parts. A coil bobbin with split pin terminals can be constructed.
