Description
【０００１】[0001]
本考案は、電線を差し込んで挟持する電線接続用の端子に関するものである。 The present invention relates to an electric wire connecting terminal for inserting and holding an electric wire.
【０００２】[0002]
図３は、従来の端子部を示す斜視図であり、図４は、従来の端子部の断面図で ある。 FIG. 3 is a perspective view showing a conventional terminal portion, and FIG. 4 is a sectional view of the conventional terminal portion.
【０００３】 図３に示すように、電線接続用端子２２は、接触金具２３、電線接触金具２４ 及び鎖錠片２５の３点の部品により構成されている。接触金具２３は、両端に下 方に向けて折り曲げた折曲げ部２７，２７を設けてあり、プリント基板２６に折 り曲げ部２７，２７を差し込んでプリント基板２６の裏面に半田付けしている。 また、接触金具２３にはバネ片２８が形成されおり、電線接触金具２４の下部に 設けられた切起し片２９を挿入すると、バネ片２８の弾性力が切起し片２９に加 わり、両者が接触導通する。電線接触金具２４は、上方側が開となったコ字形状 に折曲形成されており、互いに向き合う立上り片部３０，３０間に鎖錠片２５が 挿入されている。As shown in FIG. 3, the wire connecting terminal 22 is composed of three parts, a contact fitting 23, an electric wire contact fitting 24, and a locking piece 25. The contact fitting 23 has bent portions 27, 27 bent downward at both ends, and the bent portions 27, 27 are inserted into the printed circuit board 26 and soldered to the back surface of the printed circuit board 26. . Further, a spring piece 28 is formed on the contact fitting 23, and when the cut and raised piece 29 provided at the lower portion of the wire contact fitting 24 is inserted, the elastic force of the spring piece 28 is applied to the cut and raised piece 29, Both contact and conduct. The electric wire contact fitting 24 is bent into a U-shape with its upper side opened, and a locking piece 25 is inserted between the rising piece portions 30 facing each other.
【０００４】 図４に示すように、プリント基板２６を収納した収納ケース３１の電線挿入孔 ３２に電線１６を挿入すると、鎖錠片２５に屈曲して形成されている２つのバネ 部３３，３４の弾性により、電線１６が電線接触金具２４の一方の立上り片部３ ０に押し付けられて接触する。As shown in FIG. 4, when the electric wire 16 is inserted into the electric wire insertion hole 32 of the storage case 31 accommodating the printed circuit board 26, two spring portions 33, 34 formed by bending the locking piece 25 are formed. Due to the elasticity of the electric wire 16, the electric wire 16 is pressed against one of the rising piece portions 30 of the electric wire contact fitting 24 and comes into contact therewith.
【０００５】 従来の電線接続用端子２２には、次のような難点がある。 プリント基板２６、収納ケース３１の小型化のために、プリント基板に取り付 ける接触金具２３も必然的に小型となり、接触金具２３に設けたバネ片３３が短 い。この結果、バネ片３３にかかる応力が過大となり、バネ片３３が塑性変形を 起こし、電線接触金具２４とバネ片３３との接触不良が発生しやすい。The conventional wire connecting terminal 22 has the following drawbacks. Due to the miniaturization of the printed circuit board 26 and the storage case 31, the contact metal fitting 23 attached to the printed circuit board is also necessarily small, and the spring piece 33 provided on the contact metal fitting 23 is short. As a result, the stress applied to the spring piece 33 becomes excessively large, and the spring piece 33 is plastically deformed, so that the contact failure between the wire contact fitting 24 and the spring piece 33 is likely to occur.
【０００６】 また、部品点数が３点もあり、各部品同士の接触点が多く、接触不安定要因と なりやすく、製造コストも割高である。Further, there are three parts, and there are many contact points between the parts, which easily causes contact instability and the manufacturing cost is high.
【０００７】[0007]
本考案の目的は、部品点数１点で構成することを実現し、この結果、製造コス トを低減でき、接触点の数を削減すると共に電線を挟み込むバネ片を長く形成で き、接触の安定性がよい端子を提供することにある。 The purpose of the present invention is to realize the configuration with only one part, and as a result, the manufacturing cost can be reduced, the number of contact points can be reduced, and the spring piece for sandwiching the wire can be formed long, so that stable contact can be achieved. It is to provide a terminal having good performance.

本考案の端子は、上記課題を解決するために、基板の表面に対して直立する直 立部の一端側を電線支持部とし、前記直立部の他端側に一体に形成した延出部分 を基板に沿って折曲してバネ片を形成し、前記バネ片の自由端と前記電線支持部 との間に電線挟持部を形成したことを特徴とする。 In order to solve the above-mentioned problems, the terminal of the present invention has one end side of the upright portion which is upright with respect to the surface of the substrate as an electric wire support portion, and an extension portion integrally formed on the other end side of the upright portion. The invention is characterized in that a spring piece is formed by bending along a substrate, and an electric wire holding portion is formed between a free end of the spring piece and the electric wire supporting portion.

【００１２】 収納ケース２は、上面に蛍光灯側に取り付けるためのソケット部１４を備えて いる。また、収納ケース２の上部一隅には、収納ケース２の上面よりも一段低い 段部１５が形成され、段部１５には、収納ケース２の内部に収納されたプリント 基板５に対して直交方向から電線１６を挿入する電線挿入孔１７が設けられてい る。The storage case 2 has a socket portion 14 on the upper surface for attaching to the fluorescent lamp side. Further, a step portion 15 that is one step lower than the upper surface of the storage case 2 is formed in one corner of the upper portion of the storage case 2, and the step portion 15 is in a direction orthogonal to the printed circuit board 5 stored inside the storage case 2. An electric wire insertion hole 17 for inserting the electric wire 16 is provided.
【００１３】 電線接続用端子６は、薄肉の導電性材料をコ字形状に折り曲げて直立部１８を を形成し、直立部１８をプリント基板５の表面に対して直交方向に直立して配置 し、該直立部１８の互いに向き合う左側部１８ａと右側部１８ｃの一方を電線支 持部１９とし、即ち、図２に示すように、右側部１８ｃを電線支持部１９とし、 直立部１８の左側部１８ａの上縁に一体に延出部分１８ｄを形成し、延出部分１ ８ｄをその基部から電線支持部１９側に向け、プリント基板５に沿って折曲して バネ片２０を形成し、バネ片２０の自由端と電線支持部１９との間に形成された 間隙によって電線挟持部２１を形成してある。The wire connecting terminal 6 is formed by bending a thin conductive material into a U-shape to form an upright portion 18, and the upright portion 18 is placed upright in a direction orthogonal to the surface of the printed circuit board 5. , One of the left side portion 18a and the right side portion 18c of the upright portion 18 facing each other is the electric wire support portion 19, that is, as shown in FIG. 2, the right side portion 18c is the electric wire support portion 19, and the left side portion of the upright portion 18 is An extension portion 18d is integrally formed at the upper edge of 18a, and the extension portion 18d is bent from the base portion toward the electric wire support portion 19 side along the printed circuit board 5 to form a spring piece 20. The wire holding portion 21 is formed by the gap formed between the free end of the piece 20 and the wire supporting portion 19.
【００１４】 また、図２に示すように、直立部１８の左側部１８ａの下端及び右側部１８ｃ の下端は、プリント基板５に設けられた透孔を通して裏面側に突出され、プリン ト基板５の裏面に半田付けされる。Further, as shown in FIG. 2, the lower end of the left side portion 18 a and the lower end of the right side portion 18 c of the upright portion 18 are protruded to the back surface side through the through holes provided in the printed circuit board 5, and the printed circuit board 5 Soldered on the back side.
【００１５】 図２に示すように、電線１６を収納ケース２の電線挿通孔１７に挿入し、電線 接続用端子６の電線挟持部２１に差し込むと、バネ片２０の弾性により電線１６ が電線支持部１９に押し付けられ、電線１６が抜けずに挟持されて安定に接触す る。As shown in FIG. 2, when the electric wire 16 is inserted into the electric wire insertion hole 17 of the housing case 2 and inserted into the electric wire holding portion 21 of the electric wire connecting terminal 6, the elasticity of the spring piece 20 causes the electric wire 16 to support the electric wire. The electric wire 16 is pressed against the portion 19 and is clamped without coming off to make a stable contact.
【００１６】 なお、本実施形態では、バネ片２０は、直立部１８における左側部１８ａに延 長部分１８ｄを一体に設け、延長部分１８ｄの基部から折曲して形成しているが 、これに代えて、直立部１８の左側部１８ａと右側部１８ｃとの間に亘る正面部 １８ｂの左側に一体に延長部分を設け、この延長部分の基部から折曲して形成す ることもできる。In the present embodiment, the spring piece 20 is formed by integrally providing the extended portion 18d on the left side portion 18a of the upright portion 18 and bending it from the base portion of the extended portion 18d.
