田６により取り付けてある。Problems to be solved by conventional techniques and ideas The high-frequency coil of the technique is illustrated in FIGS.
This is the configuration shown in Figure 0. High frequency coil 1 in Figure 7
1, a coil 3 made of a large diameter wire is wound around a bobbin 2, a tap 4 is further attached, and the whole is housed in a shield case 5. As shown in an enlarged view in FIG. 8, the tap 4 is attached with solder 6 with its L-shaped tip in contact with the coil 3.

は、半田付けの代わりにスポツト溶接等を採用す
ればよいが、設備に多大な費用を要する。 In this high frequency coil 1, it is difficult to determine the mounting position of the tap 4, and in order to accurately determine the tap mounting position, a separate tap holding mechanism is required, resulting in a complicated configuration. Furthermore, as shown in FIG. 9, this high-frequency coil 1 is installed upright on a printed circuit board 7 with terminals soldered to it, but the heat generated during soldering the terminals is transferred through the terminals as shown by the arrows. This may be transmitted to the attachment part of the tap 4 to the coil 3, melting the solder 6, and causing the tap 4 to fall off. As a countermeasure to this problem, spot welding or the like may be used instead of soldering, but this requires a large amount of equipment cost.

個所に円弧部１５が形成してあり、タツプ１３は
ラクンク形状に折曲された先端部が円弧部１５内
に隙間なく挿入された状態で半田１６により固着
してある。 The high frequency coil 10 shown in FIG. 10 has a structure in which a coil 12 and a tap 13 are attached to a bobbin 11, and the whole is housed in a shield case 14. As shown enlarged in FIGS. 11 and 12, the coil 12 has an arcuate portion 15 formed at a location corresponding to the tap attachment position, and the tip of the tap 13 is bent into a loose shape. It is inserted into the arcuate portion 15 without any gaps and is fixed with solder 16.
この構成では、タツプ取付位置が比較的容易に
判別可能となる反面、円弧部１５を形成する加工

ル１０をプリント回路基板上に立設する際の熱に
より半田１６が溶けるとタツプ１３が円弧部１５
Ａより抜け出して脱落してしまうからである。 Although this configuration allows the tap attachment position to be determined relatively easily, it requires processing to form the arcuate portion 15, and furthermore, it is necessary to manage the dimensions of the arcuate portion 15. If the arc portion is larger than the specified size as shown by 15A in Fig. 13, tap 13
is loosely fitted in the arcuate portion 15A, and when the solder 16 melts due to the heat generated when the high-frequency coil 10 is installed upright on the printed circuit board, the tap 13 becomes loosely fitted in the arcuate portion 15A.
This is because they will get out of A and fall out.
そこで、タツプ１３の先端を、第１４図に示す
ようにフツク形状に折曲したフツク部１３ａと

考えられるが、この場合には、タツプ１３に曲げ
加工を必要とすると共に、フツク部１３ａを円弧
部１５又は１５Ａに掛止する作業が面倒となる。 Therefore, the tip of the tap 13 is formed into a hook portion 13a bent into a hook shape as shown in FIG. 14, and this hook portion 13a is hooked onto the arcuate portion 15 or 15A as shown in the same figure. However, in this case, the tap 13 would require bending, and the work of hooking the hook portion 13a to the arcuate portion 15 or 15A would be troublesome.
本考案は上記問題点を解決した高周波コイルを
提供することを目的とする。 The object of the present invention is to provide a high frequency coil that solves the above problems.
問題点を解決するための手段
本考案は、基板部の上面に段部を設け、タツプ

それを無くする。 The configuration in which the tap is placed between the board part and a part of the coil allows the tap to be temporarily fastened by attaching the coil, eliminating the need for special work for temporarily fastening the tap, and preventing solder from reaching the terminal part. Even if the tap melts due to the applied heat, there is no possibility that the tap will fall off from the coil.
