本考案は、ボビンの端子板の両端面に金属金具
をはめ込みリード線端子とした薄型トランス等に
適用して好適なコンパクトな構造のインダクタン
ス・トランス素子に関する。[Detailed Description of the Invention] The present invention relates to an inductance transformer element having a compact structure suitable for application to thin transformers and the like in which metal fittings are fitted into both end faces of a terminal plate of a bobbin and used as lead wire terminals.
第１図は従来の薄型トランスの構成図であり、

子を夫々示す。ボビン７は第２図に示す如く、両
端の鍔７ａの両外端下側に端子板４が設けられて
いる。端子板４には端子ピン５，６が横外方及び
下外方へ突出形成され、一方の端子ピン６に巻線
端末が巻付けられ半田処理が施されている。 Figure 1 is a configuration diagram of a conventional thin transformer.
1 is an E-type or EI-type core, 2 is a flange of the bobbin 7, 3 is a winding, 4 is a terminal plate of the bobbin, and 5 is a pin terminal. As shown in FIG. 2, the bobbin 7 is provided with terminal plates 4 on the lower sides of both outer ends of flanges 7a at both ends. Terminal pins 5 and 6 are formed on the terminal plate 4 to protrude laterally outwardly and downwardly outwardly, and a winding end is wound around one terminal pin 6 and soldered.

ン端子５の突出による占有面積が大きくなり、実
用的でない。 When a core 1 as shown in FIG. 1 is attached to a bobbin provided with a terminal plate 4 having such a terminal pin, the length l 2 of the terminal plate 4 is the same as the vertical dimension l 1 of the core 1 . is formed, the pin terminals 5,
6 naturally protrudes from the horizontal dimension l3 of core 1,
When such an inductance element or transformer element is mounted on a high-density mounting board, the area occupied by the protrusion of the pin terminals 5 becomes large, which is impractical.
また外部との電気的機械的取り付け部分となる
ピン端子部は細いので、取扱いに充分注意しても
簡単に折れ曲がり、時には折損する虞れがある。
更にピン端子部が突出しているため梱包等に際し
ても嵩張り、梱包サイズが大きくスペースが膨大
となる欠点を有することになる。 Furthermore, since the pin terminal portion which is the part for electrical and mechanical attachment to the outside is thin, it can easily bend and sometimes break even if handled with sufficient care.
Furthermore, since the pin terminal portion protrudes, it is bulky when packaged, resulting in a disadvantage that the package size is large and an enormous amount of space is required.
本考案はかかる点に鑑み、コイル端末の処理位

インダクタンス・トランス素子を提案することを
主たる目的とする。 In view of these points, the present invention appropriately sets the processing position of the coil terminal and the size of the terminal plate, and
The main purpose of the present invention is to propose an inductance transformer element of this type that eliminates the above-mentioned drawbacks by replacing the external terminal portion with a pin type and configuring it with a conductive fitting terminal.

A total of four recesses 8a into which the fitting terminals 9 are fitted are provided at both lower ends. As shown in FIG. 5, the fitting terminal 9 is made of metal and has a concave cross section, and is fitted into a recess 8a having the same shape as this cross section. Since the coil terminal side surface 9a of the fitting terminal 9 is soldered in advance, the fitting terminal 9 is inserted into the recess 8a with adhesive and fixed, and then the coil terminal is soldered to the soldered surface 9a. By housing the core 1, the transformer element is completed. In order to mount such an element on a printed circuit board or the like, when it is placed on a predetermined lead frame, it becomes electrically conductive through each fitting terminal 8, so that it can be directly soldered and fixed. Therefore, the terminal plate 8 is accommodated within the range of the dimensions W and L of the core 1, and within the range of the overall height dimension H (distance between the flanges of the bobbin).

The hole 12a for fitting the protrusion is provided. Then, both are fixed with adhesive, and the ends of the coils are soldered to the fitting terminals 11.

参照）。 FIG. 7 is a perspective view of main parts showing still another example of the present invention. As shown in FIG. 8, a split pin-shaped protrusion 13a is formed on the terminal plate 12 side of the fitting terminal 13 made of a Ti-Ni or Cu-Zn shape memory alloy, as shown in FIG.
By applying heat, the split pin shape is closed in the matrix state and inserted into the protrusion fitting hole 12a, and stress is applied to the hole 12a so that the split pin expands as it cools, so it does not come out easily ( (See Figure 9).

This is because, after being exposed and attached to a terminal board, it is heated during soldering to a printed circuit board, so that it does not undergo shape memory deformation due to the heating.

適である。 As described above, according to the present invention, in an inductance transformer element in which a bobbin for winding a coil is provided inside a set of cores and the cores are integrated, flanges are provided on both sides of the bobbin, and flanges are provided on both sides of the bobbin, and flanges are provided on both sides of the bobbin. A flat terminal plate is formed on the outer bottom part within the installation dimensions of the core, and a conductive mating terminal is attached to the bottom of the terminal plate, so it takes less bulk when packed compared to a conventional pin terminal structure. There is no tension, storage space can be used effectively, and the hassle of inserting a thin pin terminal into a small hole when attaching it to a terminal board etc. can be eliminated. This prevents the terminal portion from protruding and protruding, allowing high-density mounting.
Therefore, it is suitable for application as a thin and compact transformer with good space for office automation equipment, etc., which is increasing in number.
