Description

本発明は、プリント基板に表面実装されて、例えばリード線の先端に装着された丸形圧着端子の接続・固定に供するに好適なねじ端子に関する。   The present invention relates to a screw terminal suitable for use in connection / fixation of a round crimp terminal mounted on the surface of a printed circuit board, for example, attached to the tip of a lead wire.

プリント基板へのリード線の接続は、従来一般的には上記リード線を直接半田付けしたり、基板に設けた貫通孔にビスを挿通させ、このビスに螺合するナットを用いて基板との間にリード線を挟み込んで固定したり、或いは基板に立設したピンにリード線を巻き付けて、若しくは半田付けするようにしている。また前面にねじ端子金具を配設し、その裏面側に上記ねじ端子金具から延びて突出する半田付け片（ピン）を備えた合成樹脂製のねじ端子ブロックを用い、このねじ端子ブロックの半田付け片（ピン）をプリント基板に設けた嵌合孔に圧入し、半田付けすることでプリント基板に取り付けた上で、上記ねじ端子金具にリード線をねじ止め固定することも提唱されている（例えば特許文献１を参照）。
特開平１０−１３４８６５号公報 The connection of the lead wire to the printed circuit board is conventionally performed by soldering the lead wire directly or by inserting a screw through a through hole provided in the substrate and using a nut screwed to this screw. The lead wire is sandwiched between them and fixed, or the lead wire is wound around a pin standing on the substrate or soldered. In addition, a screw terminal block is provided on the front side, and a screw terminal block made of synthetic resin having a soldering piece (pin) protruding from the screw terminal bracket on the back side is used. It has also been proposed that a piece (pin) is press-fitted into a fitting hole provided in a printed circuit board and soldered and attached to the printed circuit board, and then a lead wire is screwed and fixed to the screw terminal fitting (for example, (See Patent Document 1).
JP-A-10-134865

しかしながら特許文献１に示されるねじ端子ブロックは、その前面に設けたねじ端子金具を安定に保持するべく大型で堅牢な構造を有しており、部品コストも比較的高い。しかもその裏面側に突出する半田付け片（ピン）をプリント基板に設けた嵌合孔に圧入し、半田付けしてプリント基板に取り付けて用いられるので、その取り扱いが面倒である。更にはプリント基板に、予め上記ねじ端子ブロックを取り付ける為の嵌合孔を開けておくことが必要なので、プリント基板における回路パターン設計の自由度が妨げられ、遣い勝手が悪いと言う不具合がある。   However, the screw terminal block disclosed in Patent Document 1 has a large and robust structure for stably holding the screw terminal fitting provided on the front surface thereof, and the parts cost is relatively high. In addition, soldering pieces (pins) protruding from the back surface side are press-fitted into fitting holes provided in the printed circuit board, soldered and attached to the printed circuit board, and handling thereof is troublesome. Furthermore, since it is necessary to make a fitting hole for attaching the screw terminal block in advance on the printed circuit board, the degree of freedom of circuit pattern design on the printed circuit board is hindered, and there is a problem that it is not easy to use.

本発明はこのような事情を考慮してなされたもので、その目的は、部品コストを抑えて簡易に製作することができ、プリント基板に簡易に装着してリード線の接続等に用いることのできる遣い勝手に優れたねじ端子を提供することにある。   The present invention has been made in view of such circumstances, and its purpose is that it can be easily manufactured at a reduced component cost, and can be easily mounted on a printed circuit board and used for connecting a lead wire or the like. The object is to provide an excellent screw terminal that can be used.

上述した目的を達成するべく本発明に係るねじ端子は、プリント基板に表面実装されるものであって、
板状の主体部と、この主体部の両端部を同じ向きにそれぞれ曲折して形成した一対の脚部と、上記主体部の上面に刻設したねじ穴とを備え、前記各脚部の先端縁部をそれぞれ面取り加工して該先端部をプリント基板に半田付けされる実装部としたことを特徴としている。 In order to achieve the above-described object, the screw terminal according to the present invention is surface-mounted on a printed circuit board,
A plate-like main body, a pair of legs formed by bending both ends of the main body in the same direction, and a screw hole formed on the upper surface of the main body; Each of the edge portions is chamfered to form a mounting portion that is soldered to a printed circuit board.

好ましくは前記ねじ穴は、請求項２に記載するように前記板状の主体部の表裏を貫通して設けられる。また請求項３に記載するように前記主体部および脚部は、プレスにより板材から一体部品として切り出した後、該一体部品の両端を折り曲げ加工して形成されるものである。尚、前記ねじ穴については、請求項４に記載するように前記主体部の中心から偏心した位置に設けることが好ましい。また請求項５に記載するように前記主体部にバーリング加工を施して前記ねじ穴を形成することも好ましい。   Preferably, the screw hole is provided so as to penetrate through the front and back of the plate-like main portion as described in claim 2. According to a third aspect of the present invention, the main body portion and the leg portion are formed by cutting both ends of the integrated component after being cut out from the plate material as an integrated component by pressing. In addition, about the said screw hole, as described in Claim 4, it is preferable to provide in the position eccentric from the center of the said main-body part. Further, it is also preferable that the screw hole is formed by performing burring processing on the main body portion.

本発明によれば、板状の主体部の両端部を同じ向きにそれぞれ曲折して一対の脚部を形成し、上記主体部の上面にねじ穴を刻設した略コの字状の形状を有し、上記各脚部の先端縁部をそれぞれ面取り加工して該先端部をプリント基板に半田付けされる実装部とした構造を有するので、プリント基板に簡易に表面実装することができ、脚部によりプリント基板の表面から離反させて位置付けられる主体部に設けられたねじ穴にねじを螺合させて、例えばリード線の先端に装着された丸形圧着端子等を容易にねじ止めして接続・固定することができる。特に前記各脚部の先端縁部をそれぞれ面取り加工して該先端部をプリント基板に半田付けされる実装部としているので、該実装部とプリント基板表面との間に入り込む半田の濡れ領域を広くすることができ、強固で安定な半田接合を可能とし得る。   According to the present invention, both ends of the plate-like main body portion are bent in the same direction to form a pair of leg portions, and a substantially U-shaped shape in which a screw hole is formed on the upper surface of the main body portion. And has a structure in which the tip edge of each leg is chamfered and the tip is soldered to the printed circuit board, so that the surface can be easily surface mounted on the printed circuit board. The screw is screwed into the screw hole provided in the main part that is positioned away from the surface of the printed circuit board by the part, and for example, a round crimp terminal attached to the tip of the lead wire is easily screwed and connected・ Can be fixed. In particular, since the tip edge of each leg is chamfered and the tip is soldered to the printed circuit board, the solder wet area that enters between the mounting and the printed circuit board surface is widened. It is possible to achieve a strong and stable solder joint.

しかも本発明に係るねじ端子は、プリント基板上に容易に表面実装することができ、予めプリント基板に端子取り付け用の取付孔等を穿つ必要がないので、その取り付け位置の制限が極めて少ない。これ故、回路パターン設計の自由度を高め得る等の二次的な効果も奏し得る。しかも板材の折り曲げ加工等によって簡易に製作することができるので、その部品コストを低減し得る等の利点もある。   Moreover, the screw terminal according to the present invention can be easily surface-mounted on a printed circuit board, and it is not necessary to previously pierce the printed circuit board with a mounting hole for attaching a terminal, so that the mounting position is extremely limited. Therefore, secondary effects such as an increased degree of freedom in circuit pattern design can be achieved. Moreover, since it can be easily manufactured by bending the plate material, there is an advantage that the cost of the parts can be reduced.

また前述したように板状の主体部の表裏を貫通してねじ穴を設けるようにすれば、主体部の板厚を有効に活用して多くのねじ溝を刻設する（ねじ溝のターン数を増やす）ことができるので、ねじとの結合強度を高めることが可能となり、また前述したようにねじ穴を前記主体部の中心から偏心した位置に設けるようにすれば、該主体部におけるねじ溝の横に確保される領域を、チップマウンタによる該ねじ端子の吸着領域として活用することができるので、自動表面実装に供されるチップ部品としての提供することが可能となる等の効果がある。   In addition, as described above, if screw holes are provided through the front and back of the plate-shaped main part, many screw grooves are engraved by effectively utilizing the plate thickness of the main part (the number of turns of the screw groove). Therefore, if the screw hole is provided at a position eccentric from the center of the main part as described above, the screw groove in the main part can be increased. Since the area secured beside each other can be used as a suction area for the screw terminal by the chip mounter, there is an effect that it can be provided as a chip component used for automatic surface mounting.

更には前記主体部にバーリング加工を施して前記ねじ穴を形成するようにすれば、主体部の板厚が薄い場合でもねじ穴を確実に設けることが可能であり、その実施形態として好適である。   Furthermore, if the main body is subjected to burring to form the screw hole, the screw hole can be reliably provided even when the main body is thin, which is preferable as an embodiment thereof. .

以下、図面を参照して本発明の一実施形態に係るねじ端子について説明する。
図１はこの実施形態に係るねじ端子の概略構成を示す斜視図であり、図２はその部分断面図、図３はその平面構成図をそれぞれ示している。図において１は板状の主体部、２,２は上記主体部１の両端部を同じ向きにそれぞれ曲折して形成された一対の脚部、そして３は上記主体部１の上面に、特にその表裏を貫通して設けられたねじ穴である。 Hereinafter, a screw terminal according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a perspective view showing a schematic configuration of a screw terminal according to this embodiment, FIG. 2 is a partial sectional view thereof, and FIG. 3 is a plan view thereof. In the figure, 1 is a plate-like main body, 2 and 2 are a pair of legs formed by bending both ends of the main body 1 in the same direction, and 3 is an upper surface of the main body 1, It is a screw hole provided through the front and back.

ちなみにこのねじ端子は、例えば厚み１.６ｍｍの黄銅板（板材）からプレスにより所定形状に切り出した部品素材を、穴開け加工、折り曲げ加工等を施すことにより製作されるものであり、例えば幅略５ｍｍ、長さ１０ｍｍ、高さ６ｍｍの略コの字形状をなすチップ部品として構成されている。特にこのねじ端子の前述した一対の各脚部２,２の先端縁部２ａは、例えば０.５ｍｍの径にてそれぞれ面取り加工されており、これによって該脚部２,２の先端部２ｂがプリント基板に半田付けされる実装部として設定されている。また前記ねじ穴３は、前記主体部１の中心からその長手方向に偏心した位置に、例えば３ｍｍ径のものとして刻設される。   By the way, this screw terminal is manufactured by, for example, subjecting a part material cut out from a brass plate (plate material) having a thickness of 1.6 mm to a predetermined shape by pressing, drilling, bending, etc. It is configured as a chip component having a substantially U-shape of 5 mm, a length of 10 mm, and a height of 6 mm. In particular, the tip edge portions 2a of the pair of leg portions 2, 2 of the screw terminal are chamfered, for example, with a diameter of 0.5 mm, so that the tip portions 2b of the leg portions 2, 2 are formed. It is set as a mounting part to be soldered to the printed circuit board. The screw hole 3 is engraved with a diameter of 3 mm, for example, at a position eccentric in the longitudinal direction from the center of the main body 1.

尚、ねじ穴３を挟んで前記主体部１の両縁部にそれぞれ張り出した凸部４ａ,４ａは、前述したように板材から切り出した部品素材にねじ穴３を形成する際、該部品素材を保持するべく設けられた保持片４,４の一部である。この凸部４ａ,４ａについては、ねじ端子として格別な機能を呈するものではないので、主体部１の縁部に沿って切り落とすことも可能である。   The protrusions 4a and 4a projecting from both edge portions of the main body 1 with the screw hole 3 interposed therebetween, when forming the screw hole 3 in the component material cut out from the plate material as described above, It is a part of the holding pieces 4 and 4 provided to hold. Since the convex portions 4 a and 4 a do not exhibit a special function as a screw terminal, they can be cut off along the edge of the main portion 1.

即ち、このねじ端子は、例えば図４にその概略的な製作手順を模式的に示すように、先ず図４(ａ)に示すように主体部１および一対の脚部２,２を展開し、更にねじ穴３を形成する際に用いる一対の保持部４,４を主体部１の両縁に設けた略十文字形状の部品素材を、所定の板材からプレス加工により一体部品として切り出す。次いで図４(ｂ)に示すように上記部品素材の上記保持部４,４を治具５,５を用いて保持し、前記主体部１の中心から偏心した位置に丸穴を穿ち、この丸穴にねじ溝を刻設してねじ穴３を形成する。   That is, for example, as shown schematically in FIG. 4 in a schematic manufacturing procedure, the screw terminal first expands the main body 1 and the pair of legs 2 and 2 as shown in FIG. Further, a substantially cross-shaped part material provided with a pair of holding parts 4, 4 used at the time of forming the screw hole 3 on both edges of the main part 1 is cut out from a predetermined plate material as an integrated part by pressing. Next, as shown in FIG. 4 (b), the holding parts 4, 4 of the component material are held using jigs 5, 5, and a round hole is formed at a position eccentric from the center of the main body 1. A screw groove 3 is formed by cutting a screw groove in the hole.

また図４(ｃ)に示すように、プレスにより部品素材を切り出した際、その縁部に生じるバリを切り落として該縁部を面打ち加工する。この面打ち加工については、少なくとも脚部２,２の先端部となる部位に対して行えば十分である。その後、図４(ｄ)に示すように前述した保持部４,４を切り落とし、上記部品素材を前述した一対の脚部２,２を確保し得る位置（点線で示す）にて同一方向に折り曲げ加工し、前述した略コの字形状をなすねじ端子を形成する。   Further, as shown in FIG. 4C, when a component material is cut out by pressing, burrs generated at the edge portions are cut off and the edge portions are faced. It is sufficient to perform this surface punching process on at least the portion that becomes the tip of the legs 2 and 2. After that, as shown in FIG. 4 (d), the above-mentioned holding parts 4, 4 are cut off, and the part material is bent in the same direction at a position (indicated by a dotted line) where the above-mentioned pair of leg parts 2, 2 can be secured. The screw terminal which processes and forms the substantially U shape mentioned above is formed.

このようにして製作されて略コの字形状をなすねじ端子は、例えば図５に示すように前記一対の脚部２,２の先端部２ｂを実装部としてプリント基板１０の導電パターン１１上に半田付けされて該プリント基板１０に表面実装される。そして前記ねじ穴３に螺合するねじ１２を用いて、例えばリード線１３の先端にかしめ装着された丸形圧着端子１４のねじ止めによる接続・固定に供される。この際、プリント基板１０に表面実装されたねじ端子の脚部２,２の先端部２ｂ、特にその先端縁部２ａがそれぞれ面取りされており、前述したプレス加工によって生じたバリ（突起）が除去されているので、半田１５はその溶融によって導電パターン１１上から脚部２,２の先端部、およびその間に形成される隙間に掛けて良好に回り込む。従ってプリント基板１０への半田付けによるねじ端子の表面実装を、機械的に安定に、しかも強固に行うことができ、ねじ穴３へのねじ１２のねじ締め力に対する強度を十分に高いものとすることができる。   As shown in FIG. 5, for example, as shown in FIG. 5, the screw terminal manufactured in this manner is formed on the conductive pattern 11 of the printed circuit board 10 with the tip portions 2b of the pair of leg portions 2 and 2 as a mounting portion. And is surface-mounted on the printed circuit board 10. Then, the screw 12 that is screwed into the screw hole 3 is used for connection / fixing by screwing, for example, a round crimp terminal 14 that is caulked to the tip of the lead wire 13. At this time, the tip portions 2b of the screw terminal legs 2 and 2 mounted on the printed circuit board 10 are chamfered, particularly the tip edge portion 2a thereof, and the burrs (protrusions) generated by the above-described pressing are removed. As a result, the solder 15 wraps well over the conductive pattern 11 from the top of the conductive pattern 11 to the tip portions of the legs 2 and 2 and the gap formed therebetween. Therefore, the surface mounting of the screw terminal by soldering to the printed circuit board 10 can be performed mechanically and stably, and the strength against the screw tightening force of the screw 12 to the screw hole 3 is sufficiently high. be able to.

また前述したようにねじ穴３を、図３に示すように主体部１の中心からその長手方向に偏心した位置に設けるようにしているので、主体部１の表面の上記ねじ穴３の側部の領域を図示しないチップマウンタの吸着ヘッドによる吸着領域Ａとして有効に活用することができる。従ってねじ穴３の存在によりねじ端子の吸着が妨げられることがないので、該ねじ端子のチップマウンタを活用した自動表面実装を容易に行うことが可能となる等の効果が奏せられる。   Further, as described above, the screw hole 3 is provided at a position eccentric in the longitudinal direction from the center of the main body 1 as shown in FIG. This area can be effectively utilized as a suction area A by a suction head of a chip mounter (not shown). Accordingly, since the screw terminals 3 are not hindered by the presence of the screw holes 3, the automatic surface mounting using the chip mounter of the screw terminals can be easily performed.

更には本発明に係るねじ端子は、板材から切り出して折り曲げ加工し、その主体部１にねじ穴３を設けると共に、脚部２,２の先端縁部を面打ち加工しただけの簡易な構成なので、その製作コストが非常に安価である。しかもプリント基板１０に取付孔等を設けることなく簡易に表面実装することができるので、その取り扱い性に優れている。従ってプリント基板１０に対する回路パターン設計の自由度を妨げることが少なく、プリント基板１０上の比較的任意な位置にリード線１３のねじ止め位置を容易に設定することができる等の効果が奏せられる。   Furthermore, the screw terminal according to the present invention has a simple structure in which the screw terminal 3 is cut out from the plate material and bent, the screw hole 3 is provided in the main body portion 1, and the tip edge portions of the leg portions 2 and 2 are simply beveled. The production cost is very low. And since it can be easily surface-mounted without providing a mounting hole etc. in the printed circuit board 10, it is excellent in the handleability. Accordingly, the degree of freedom of circuit pattern design with respect to the printed circuit board 10 is hardly hindered, and the effect that the screwing position of the lead wire 13 can be easily set at a relatively arbitrary position on the printed circuit board 10 is achieved. .

尚、上述したねじ端子を量産する場合には、図８(ａ)〜(ｄ)にその概略的な手順を示すように、先ずその両縁のキャリア部にパイロット穴２１を設けた長尺の板材２２をプレス金型に送り込んで図８(ａ)に示すようにネジ用下穴を穿ち、その内面をタップ加工してねじ穴３を形成する。その後、図８(ｂ)に示すように上記ねじ穴３を基準として板材２２を打ち抜き加工して、ネジ端子を展開した形状に切り出す。そして脚部２,２の先端縁部となる部位を面打ち加工した後、図８(ｃ)に示すように主体部１の両端をそれぞれ折り曲げ加工して脚部２,２を形成する。しかる後、図８(ｄ)に示すように前記板材２２のキャリア部から、上述した如くプレス加工したネジ端子の部分を切り出す（切り落とす）ようにすれば良い。   In addition, when mass-producing the screw terminals described above, as shown in the schematic procedure in FIGS. 8A to 8D, first, a long length in which pilot holes 21 are provided in the carrier portions on both edges. The plate material 22 is fed into a press die, and a screw pilot hole is formed as shown in FIG. 8A, and the inner surface thereof is tapped to form the screw hole 3. Thereafter, as shown in FIG. 8B, the plate material 22 is punched out with the screw hole 3 as a reference, and the screw terminal is cut out into a developed shape. Then, after the surface portions of the leg portions 2 and 2 are chamfered, both ends of the main body portion 1 are bent to form the leg portions 2 and 2 as shown in FIG. Thereafter, as shown in FIG. 8 (d), the portion of the screw terminal pressed as described above may be cut out (cut off) from the carrier portion of the plate member 22.

このようにしてプレス加工によりねじ端子を形成することで、ねじ端子を効率よく連続して量産することができる。このとき図８(ｂ)に示すようにブランク加工する際の脚部２,２の長さを、ねじ穴３に螺合させるネジ（図示せず）の長さに合わせて調整することで、具体的にはねじ穴３を設けた主体部１から脚部２,２の先端部までの長さをねじ仕様に合わせて調整しておけば、脚部２,２の高さを容易に設定することができる。従って各種のねじ仕様に応じた高さのねじ端子を容易に実現することができる。   By forming the screw terminals by press working in this way, the screw terminals can be mass-produced efficiently and continuously. At this time, as shown in FIG. 8B, by adjusting the length of the legs 2 and 2 when blanking to the length of a screw (not shown) screwed into the screw hole 3, Specifically, the height of the legs 2 and 2 can be easily set by adjusting the length from the main body 1 provided with the screw holes 3 to the tips of the legs 2 and 2 according to the screw specifications. can do. Therefore, screw terminals having heights corresponding to various screw specifications can be easily realized.

また主体部１にねじ穴３を設けるに際して、その下穴をバーリング加工により、その下面側に突出する絞り込み穴として形成することも非常に有用である。このようにしてバーリング加工により筒状に形成した部位の内面にタップ加工を施してねじ穴３を形成すれば、図９にその外観斜視図を、また図１０にその部分断面図を示すようにねじ穴３の実効長を、主体部１の板厚の約２倍とすることができるので、ねじ穴３としても必要タップ数を確実に確保することができる。特にねじ径に比較して主体部１の板厚が薄い場合であっても、ねじ穴３として確実に機能させるべきタップ数を備えたねじ穴３を確実に形成することができる。またそのバーリング突起は、脚部２,２によって囲まれる主体部１の下面側に突出するだけなので、ねじ端子としての機能を阻害する虞がなく、従ってその実用的利点が多大である。またバーリングの高さを変えることで、様々なねじサイズに対応可能となるとなる等の効果が奏せられる。   In addition, when the screw hole 3 is provided in the main body 1, it is also very useful to form the prepared hole as a narrowing hole protruding to the lower surface side by burring. When tapping is performed on the inner surface of the portion formed into a cylindrical shape by burring in this way to form the screw hole 3, as shown in FIG. 9, its external perspective view and in FIG. 10, its partial cross-sectional view are shown. Since the effective length of the screw hole 3 can be about twice the plate thickness of the main body 1, the necessary number of taps can be reliably ensured even for the screw hole 3. In particular, even when the plate portion of the main body 1 is thinner than the screw diameter, the screw hole 3 having the number of taps that should function reliably as the screw hole 3 can be reliably formed. Moreover, since the burring protrusion only protrudes to the lower surface side of the main body 1 surrounded by the legs 2, 2, there is no possibility of hindering the function as a screw terminal, and therefore its practical advantage is great. Further, by changing the height of the burring, effects such as being able to cope with various screw sizes can be obtained.

尚、本発明は上述した実施形態に限定されるものではない。例えば図７に示されるように脚部２の先端部を更に内側に折り曲げて、該脚部２の先端部のより広い領域を実装面として用いることも可能である。但し、この場合には２段階の曲げ加工が必要となる。またここでは片方の脚部２の先端だけを折り曲げ加工しているが、両方の脚部２,２の先端部をそれぞれ曲げ加工することも勿論可能である。また場合によっては、外側に曲げ加工することも勿論可能である。   The present invention is not limited to the embodiment described above. For example, as shown in FIG. 7, it is also possible to bend the tip of the leg 2 further inward and use a wider area of the tip of the leg 2 as the mounting surface. In this case, however, a two-stage bending process is required. Here, only the tip of one leg 2 is bent, but it is of course possible to bend the tips of both legs 2,2. In some cases, it is of course possible to bend outward.

また上述した実施形態においては前記保持部４,４を切り落とすようにしているが、これらの保持部４,４を脚部２,２と同じ向きに折り曲げ、これによって主体部１の剛性（曲げ強度）を高めるようにしても良い。この保持部４,４の折り曲げについては、脚部２,２の折り曲げと同時にプレス加工により一括して行うようにすれば、製造コストの増大を伴うことがない。またねじ端子の形成材料やその大きさ等については、各種仕様に応じたものであれば良く、要は本発明はその要旨を逸脱しない範囲で種々変形して実施することができる。   In the above-described embodiment, the holding portions 4 are cut off. However, the holding portions 4 are bent in the same direction as the leg portions 2, and thereby the rigidity (bending strength) of the main portion 1 is obtained. ) May be enhanced. If the holding portions 4 and 4 are bent at the same time as the legs 2 and 2 by pressing, the manufacturing cost does not increase. Further, the material for forming the screw terminal, its size, and the like may be any one according to various specifications, and the present invention can be implemented with various modifications without departing from the gist thereof.
