【考案の詳細な説明】
本考案の主な目的は、ラジオ受信機用ループア
ンテナの量産性を改善し、生産コストを安くする
ことにある。[Detailed Description of the Invention] The main purpose of the invention is to improve mass productivity of loop antennas for radio receivers and to reduce production costs.
本考案のループアンテナは、図面に例示したよ
うに、ループ状の基枠１の凹溝２内に、予め太目
の線材で巻回されたコイル３を収納し、基枠１に
ループ状の蓋枠４をかぶせて接合した構造のルー

位置決め用の突棒７を凹孔５に嵌合した状態で、
基枠１と蓋枠４とを超音波加工などにより接合し
たものである。 As illustrated in the drawing, the loop antenna of the present invention stores a coil 3 pre-wound with a thick wire in a groove 2 of a loop-shaped base frame 1, and a loop-shaped lid is attached to the base frame 1. In a loop antenna having a structure in which a frame 4 is covered and joined, an appropriate number of convex bodies 6 having concave holes 5 are provided inside the concave groove 2 of the base frame 1, and the coil 3 housed in the concave groove 2 is Hooked on the outside of the convex body 6 and held elastically, with the positioning protrusion 7 provided inside the lid frame 4 fitted into the recessed hole 5,
A base frame 1 and a lid frame 4 are joined by ultrasonic processing or the like.
なお、図中８はリード線、９はリード線接続部
の短絡を防ぐためのガイド用凸体である。 In the figure, 8 is a lead wire, and 9 is a guide convex body for preventing a short circuit at the lead wire connection portion.
以上の構造において、基枠１に設けられた凸体
６は、蓋枠４の位置決め用の突棒７を嵌合する凹
孔５を設けるためのものであるが、これを凹溝２
内の内側寄りに設けて、その外側に予め第５図の
ように太目の線材で巻回されたコイル３を引掛け
るように嵌合すれば、コイル３は第２図に示すよ
うに、凸体６によつて少し彎曲された状態に弾性
変形して弾性的に保持される。 In the above structure, the convex body 6 provided on the base frame 1 is for providing the concave hole 5 into which the protruding rod 7 for positioning the lid frame 4 is fitted, but this convex body 6 is provided in the concave groove 2.
If the coil 3, which is pre-wound with thick wire material as shown in FIG. It is elastically deformed and held in a slightly curved state by the body 6.
すなわち、凸体６は本来の位置決めの役割を果
たすのみでなく、コイル３を弾性的に保持して仮
止めするという役目も兼ねている。このようにコ
イル３の仮止めが簡単にできるため、蓋枠４を基
枠１にかぶせて、その合せ目を超音波加工などに
より接合するまでの作業性がよくなり、生産コス
トを安くできるという効果がある。 That is, the convex body 6 not only plays the role of original positioning, but also plays the role of elastically holding the coil 3 and temporarily fixing it. Since the coil 3 can be easily temporarily fastened in this way, the process from covering the lid frame 4 to the base frame 1 and joining the seams by ultrasonic processing is improved, and production costs can be reduced. effective.
なお、凸体６は、第２図のような円筒形でもよ
いし、第６図のように基枠１の内側の壁とくつつ
いた形状のものでもよい。 The convex body 6 may have a cylindrical shape as shown in FIG. 2, or may have a shape that is attached to the inner wall of the base frame 1 as shown in FIG. 6.
第１図は本考案に係るループアンテナの外観を

５：凹孔、６：凸体、７：突棒。
Fig. 1 is a perspective view showing the external appearance of the loop antenna according to the present invention, Figs. 2 and 3 are plan views showing the base frame and cover frame, respectively, and Fig. 4 is a cross section taken along line A-A in Fig. 1. Figure 5 is a perspective view showing the original form of the coil.
FIG. 6 is a plan view showing another example of the base frame. 1: Base frame, 2: Concave groove, 3: Coil, 4: Lid frame,
5: concave hole, 6: convex body, 7: protruding rod.
