Description

本発明は、導電ケーブルとプリント回路基板の接触端子部との電気的接続部材として使用される基板用端子及び基板用コネクタに関する。   The present invention relates to a board terminal and a board connector used as an electrical connection member between a conductive cable and a contact terminal portion of a printed circuit board.

プリント回路基板の周縁部に形成された接触端子部と、導電ケーブルとの接続部材として使用される基板用コネクタに関しては、その用途に応じて、従来、様々な方式が提案されているが、本発明に関連するものとして、例えば、特許文献1記載の「プリント基板用コネクタ」あるいは特許文献2記載の「カードエッジコネクタ」などがある。   Various methods have been proposed for board connectors used as connecting members between contact terminals formed on the peripheral edge of a printed circuit board and conductive cables, depending on the application. For example, “printed circuit board connector” described in Patent Document 1 or “card edge connector” described in Patent Document 2 are related to the invention.

特許文献1記載の「プリント基板用コネクタ」は、コネクタハウジングの端子収容室に収容する接続端子の弾性接触片と、該弾性接触片に対向する該接続端子の天板部との間にプリント回路基板を挟持接続させるものである。   A “printed circuit board connector” described in Patent Document 1 includes a printed circuit between an elastic contact piece of a connection terminal housed in a terminal housing chamber of a connector housing and a top plate portion of the connection terminal facing the elastic contact piece. The substrate is sandwiched and connected.

特許文献2記載の「カードエッジコネクタ」は、筺形のアウターハウジング内に互いに対向した状態で回動可能に支持された複数のインナーハウジングの間にプリント回路基板の端部を挟持することにより、各インナーハウジングに収容された導電端子の当接部とプリント回路基板とを接続するものである。   The "card edge connector" described in Patent Document 2 is obtained by sandwiching the end of the printed circuit board between a plurality of inner housings that are rotatably supported in a saddle-shaped outer housing. The contact portion of the conductive terminal accommodated in each inner housing is connected to the printed circuit board.

特許文献1記載の「プリント基板用コネクタ」及び特許文献2記載の「カードエッジコネクタ」(以下、「コネクタ」という。)は、プリント回路基板の周縁方向に沿って複数の端子を配列した状態で接続する場合、複数の端子の配置間隔を当該端子の横幅より広く確保しなければならないので、コネクタの狭ピッチ化の要請に応えることが困難である。また、引用文献2記載のコネクタは、基板上下の回路を接続することはできるが、端子に基板受け部が無いため、自動車の使用環境の信頼性に欠ける。   The “printed circuit board connector” described in Patent Document 1 and the “card edge connector” (hereinafter referred to as “connector”) described in Patent Document 2 are arranged in a state in which a plurality of terminals are arranged along the peripheral direction of the printed circuit board. In the case of connection, it is difficult to meet the demand for a narrower pitch of the connector because the arrangement interval of the plurality of terminals must be ensured wider than the lateral width of the terminals. Moreover, although the connector of the cited reference 2 can connect the circuit of board | substrate upper and lower sides, since there is no board | substrate receiving part in a terminal, it lacks the reliability of the use environment of a motor vehicle.

即ち、引用文献1,2記載のコネクタにおいて狭ピッチ化を図るためには、端子の横幅を小さくする必要があるが、端子の横幅を小さくすると、その剛性が低下し、プリント回路基板に対する挟持力が弱まり、接触信頼性が悪化するので、端子の横幅減少には限界がある。   That is, in order to reduce the pitch in the connectors described in the cited documents 1 and 2, it is necessary to reduce the lateral width of the terminal. However, if the lateral width of the terminal is reduced, the rigidity is lowered and the clamping force to the printed circuit board is reduced. Since the contact reliability is deteriorated and the contact reliability is deteriorated, there is a limit in reducing the lateral width of the terminal.

本発明が解決しようとする課題は、コネクタの狭ピッチ化及び製造工程における生産性向上を図ることができ、接触信頼性も良好な基板用端子及びこれを用いた基板用コネクタを提供することにある。   The problem to be solved by the present invention is to provide a board terminal and a board connector using the same, which can reduce the pitch of the connector and improve the productivity in the manufacturing process, and have good contact reliability. is there.

本発明の基板用端子は、導電性を有する平板材を加工して形成された基板用端子であって、プリント回路基板の周縁部の両面に形成された接触端子部及び基板受け接点にそれぞれ接触した状態で前記プリント回路基板を挟持するために対向配置されたバネ接触部及び基板受け部を有する端子本体を備え、前記端子本体を構成する平板材の一部をその平面方向が前記プリント回路基板の平面方向と交差する状態に配置して前記基板受け部を形成し、前記基板受け部に断面形状が略コ字形状をした凹状領域を設けたことを特徴とする。   The board terminal of the present invention is a board terminal formed by processing a conductive flat plate material, and contacts the contact terminal part and the board receiving contact formed on both sides of the peripheral part of the printed circuit board, respectively. A terminal main body having a spring contact portion and a substrate receiving portion arranged to face each other in order to sandwich the printed circuit board in a state where the printed circuit board is sandwiched. The substrate receiving portion is formed so as to intersect with the planar direction of the substrate, and a concave region having a substantially U-shaped cross section is provided in the substrate receiving portion.

このような構成とすれば、前記端子本体を構成する平板材の一部をその平面方向が前記プリント回路基板の平面方向と交差する状態に配置して前記基板受け部を形成し、前記基板受け部に断面形状が略コ字形状をした凹状領域を設けたことにより、前記基板受け部として必要な剛性を確保しつつ、この部分の横幅の増大を回避することができる。従って、基板用端子をプリント回路基板の周縁に沿って複数配置する場合の配置間隔を小さくすることが可能となり、基板用コネクタの狭ピッチ化を図ることができる。なお、前記「横幅」とは、基板用端子をプリント回路基板の周縁に沿って複数配置した状態で接続するとき、基板用端子同士が隣り合う方向のサイズをいう(以下、同じ。)。   With such a configuration, a part of the flat plate material constituting the terminal body is arranged in a state in which the plane direction intersects the plane direction of the printed circuit board to form the board receiving part, and the board receiving part By providing a concave region having a substantially U-shaped cross section in the portion, it is possible to avoid an increase in the lateral width of this portion while ensuring the rigidity necessary for the substrate receiving portion. Therefore, it is possible to reduce the arrangement interval when a plurality of board terminals are arranged along the peripheral edge of the printed circuit board, and the board connector can be narrowed. The “lateral width” refers to a size in a direction in which the board terminals are adjacent to each other when a plurality of board terminals are arranged along the periphery of the printed circuit board (hereinafter the same).

また、端子本体を構成する平板材をその平面方向がプリント回路基板の平面方向と直交する状態に配置して基板受け部を形成し、基板受け部に断面形状が略コ字形状をした凹状領域を設けたことにより、端子本体の剛性が高まり、基板用端子をプリント回路基板に接続したときにバネ接触部の弾性力によって基板受け部が受ける押圧力に対する剛性が高まるので、プリント回路基板に対する接触圧力が安定し、接触信頼性も良好となる。   Further, the flat plate material constituting the terminal body is arranged in a state in which the plane direction thereof is orthogonal to the plane direction of the printed circuit board to form a substrate receiving portion, and the substrate receiving portion has a concave region having a substantially U-shaped cross section. Since the rigidity of the terminal body is increased, and the rigidity against the pressing force received by the board receiving part by the elastic force of the spring contact part when the board terminal is connected to the printed circuit board, the contact with the printed circuit board is increased. The pressure is stable and the contact reliability is also good.

ここで、端子本体を構成する平板材の一部を減厚して折り曲げることにより前記バネ接触部の側面を覆う保護壁を形成することが望ましい。このような構成とすれば、バネ接触部と保護壁との隙間を狭隘化し、バネ接触部付近の横幅の増大を回避することができるため、基板用コネクタの狭ピッチ化に有効であり、製造工程では、平板材において一つの基板用端子を形成するため材料占有幅を狭くすることができるため、生産性向上に有効である。   Here, it is desirable to form a protective wall that covers the side surface of the spring contact portion by thinning and bending a part of the flat plate material constituting the terminal body. With such a configuration, the gap between the spring contact portion and the protective wall can be narrowed, and an increase in the lateral width near the spring contact portion can be avoided. In the process, since one board terminal is formed in the flat plate material, the material occupation width can be narrowed, which is effective in improving productivity.

また、前記基板受け部の横幅を前記バネ接触部の支持部材の横幅より小さくすることが望ましい。このような構成とすれば、基板用端子をプリント回路基板の周縁に沿って複数配置する場合、隣り合う基板用端子の基板受け部とバネ接触部とがプリント回路基板を挟んで交互に位置するように配置することにより、二つの基板用端子のバネ接触部の支持部材の横幅の和より狭いスペース内に、二つの基板用端子を対向配置することが可能となるため、基板用コネクタの狭ピッチ化に有効である。   In addition, it is preferable that the lateral width of the substrate receiving portion is smaller than the lateral width of the support member of the spring contact portion. With such a configuration, when a plurality of board terminals are arranged along the periphery of the printed circuit board, the board receiving parts and spring contact parts of adjacent board terminals are alternately positioned with the printed circuit board interposed therebetween. By arranging in this manner, the two board terminals can be arranged to face each other in a space narrower than the sum of the lateral widths of the support members of the spring contact portions of the two board terminals. Effective for pitching.

さらに、前記保護壁の一部を前記端子本体に係止することが望ましい。このような構成とすれば、端子本体と保護壁との一体性が高まり、端子本体の剛性を増大させることができる。   Furthermore, it is desirable that a part of the protective wall is locked to the terminal body. With such a configuration, the integrity of the terminal body and the protective wall is increased, and the rigidity of the terminal body can be increased.

一方、前記平板材の一部を折り曲げて前記基板受け部の凹状領域内に嵌め込むことにより前記基板受け部の側面の少なくとも一部を覆う基板受け部保護壁を設けることが望ましい。このような構成とすれば、製造工程における作業性が向上する。   On the other hand, it is desirable to provide a substrate receiving part protective wall that covers at least a part of the side surface of the substrate receiving part by bending a part of the flat plate material and fitting it into the concave region of the substrate receiving part. With such a configuration, workability in the manufacturing process is improved.

また、前記基板受け部保護壁を前記基板受け部に係止する係止手段を設けることが望ましい。このような構成とすれば、基板受け部と基板受け部保護壁との一体性が高まり、端子本体の剛性を増大させることができる。   Moreover, it is desirable to provide a locking means for locking the substrate receiving portion protection wall to the substrate receiving portion. With such a configuration, the integrity of the substrate receiving portion and the substrate receiving portion protective wall is increased, and the rigidity of the terminal body can be increased.

この場合、前記係止手段として、前記基板受け部及び前記基板受け部保護壁に互いに嵌合する凹凸嵌合構造を設けることができる。このような構成とすれば、プリント回路基板の周縁をバネ接触部と基板受け部との間に挟持したとき、基板受け部に加わるバネ押圧力の一部を基板受け部保護壁で受けることが可能となるため、端子本体の剛性向上を図ることができる。   In this case, a concave-convex fitting structure can be provided as the locking means to be fitted to the substrate receiving portion and the substrate receiving portion protective wall. With such a configuration, when the peripheral edge of the printed circuit board is sandwiched between the spring contact portion and the substrate receiving portion, a part of the spring pressing force applied to the substrate receiving portion can be received by the substrate receiving portion protection wall. Therefore, the rigidity of the terminal body can be improved.

また、前記係止手段として、前記基板受け部の凹状領域内に嵌め込まれた前記基板受け部保護壁の周縁の少なくとも一部を前記凹状領域に押圧状態で当接させた接触係合構造を設けることもできる。   Further, as the locking means, a contact engagement structure is provided in which at least a part of the peripheral edge of the substrate receiving part protective wall fitted in the recessed area of the substrate receiving part is brought into contact with the recessed area in a pressed state. You can also

このような構成とすれば、前述の凹凸嵌合構造の場合と同様、プリント回路基板の周縁をバネ接触部と基板受け部との間に挟持したとき、基板受け部に加わるバネ押圧力の一部を基板受け部保護壁で受けることが可能となるため、端子本体の剛性向上を図ることができる。   With such a configuration, as in the case of the concave-convex fitting structure described above, when the peripheral edge of the printed circuit board is sandwiched between the spring contact portion and the substrate receiving portion, the spring pressing force applied to the substrate receiving portion is reduced. Since the portion can be received by the substrate receiving portion protective wall, the rigidity of the terminal body can be improved.

前記接触係合構造の形成方法は限定しないが、例えば、基板受け部の凹状領域内に嵌め込まれた基板受け部保護壁に対し、当該基板受け部保護壁がその面方向に広がるような加工を施して、基板受け部保護壁の周縁を凹状領域の内面に押圧状態で当接させる方法などを採用することができる。   Although the method for forming the contact engagement structure is not limited, for example, processing is performed so that the substrate receiving part protective wall extends in the surface direction with respect to the substrate receiving part protective wall fitted in the concave region of the substrate receiving part. And a method of bringing the peripheral edge of the substrate receiving portion protective wall into contact with the inner surface of the concave region in a pressed state can be employed.

また、前記バネ接触部を前記基板受け部に向かって付勢する補助バネを設けることもできる。このような構成とすれば、プリント回路基板に対する挟持力を強化することができるので、接触信頼性の向上に有効である。   In addition, an auxiliary spring that urges the spring contact portion toward the substrate receiving portion may be provided. With such a configuration, the clamping force with respect to the printed circuit board can be enhanced, which is effective in improving the contact reliability.

さらに、前記バネ接触部及び前記基板受け部に対して略直角方向からの加圧によりケーブルを圧着可能なケーブル圧着部を設けることもできる。このような構成とすれば、端子圧着工程などにおける端子本体のセット高さを低くすることができるため、作業性の向上に有効である。   Furthermore, a cable crimping part capable of crimping a cable by pressurization from a substantially perpendicular direction to the spring contact part and the substrate receiving part can be provided. With such a configuration, the set height of the terminal body in the terminal crimping process or the like can be reduced, which is effective for improving workability.

次に、本発明の基板用コネクタは、前述した基板用端子と、複数の前記基板用端子を保持するハウジングと、を備えたことを特徴とする。このような構成とすれば、コネクタの狭ピッチ化を図ることができる。   Next, a board connector according to the present invention includes the board terminals described above and a housing that holds the plurality of board terminals. With such a configuration, it is possible to reduce the connector pitch.

本発明により、コネクタの狭ピッチ化及び製造工程における生産性向上を図ることができ、接触信頼性も良好な基板用端子及びこれを用いた基板用コネクタを提供することができる。   According to the present invention, it is possible to provide a connector for a board and a board connector using the same, which can reduce the pitch of the connector and improve the productivity in the manufacturing process and have good contact reliability.

図1〜図8に示すように、本発明の第1実施形態である基板用端子100は、導電性を有する平板材を加工して形成されたものであり、プリント回路基板200の周縁部の両面に交互に形成された接触端子部201及び基板受け接点202にそれぞれ接触した状態でプリント回路基板200を挟持するために対向配置されたバネ接触部11及び基板受け部12を有する側面視コ字状の端子本体10を備えている。基板受け部12は、端子本体10を構成する平板材の一部をその平面方向がプリント回路基板200の平面方向と交差する状態に配置することによって形成されている。   As shown in FIGS. 1 to 8, the board terminal 100 according to the first embodiment of the present invention is formed by processing a flat plate material having conductivity, and is formed on the peripheral portion of the printed circuit board 200. The U-shaped side view having the spring contact portion 11 and the substrate receiving portion 12 arranged to face each other to sandwich the printed circuit board 200 in contact with the contact terminal portions 201 and the substrate receiving contact 202 alternately formed on both surfaces. Shaped terminal body 10 is provided. The board receiving portion 12 is formed by arranging a part of the flat plate material constituting the terminal body 10 in a state where the plane direction intersects the plane direction of the printed circuit board 200.

基板受け部12には断面形状が略コ字形状をした凹状領域12aが設けられ、その横幅12wは支持部材13の横幅13wより小さく形成され、平板材の一部を減厚して折り曲げることによりバネ接触部11の側面を覆う保護壁14が形成され、平板材の一部を折り曲げて基板受け部12の凹状領域12a内に嵌め込むことにより基板受け部12の側面の一部を覆う基板受け部保護壁15が形成されている。基板受け部12のバネ接触部11側には、バネ接触部11に向かって突出した複数の受け側接点部16が設けられている。   The substrate receiving portion 12 is provided with a concave region 12a having a substantially U-shaped cross section. The lateral width 12w is smaller than the lateral width 13w of the support member 13, and a portion of the flat plate material is reduced and bent. A protective wall 14 that covers the side surface of the spring contact portion 11 is formed, and a substrate receiver that covers a portion of the side surface of the substrate receiving portion 12 by bending a portion of the flat plate material and fitting it into the concave region 12a of the substrate receiving portion 12. A part protection wall 15 is formed. A plurality of receiving side contact portions 16 protruding toward the spring contact portion 11 are provided on the spring contact portion 11 side of the substrate receiving portion 12.

ここで、横幅12w,13wとは、基板用端子100をプリント回路基板200の周縁に沿って複数配置した状態で接続するとき、基板用端子100同士が隣り合う方向(図1中の矢線X方向)のサイズをいう。端子本体10を構成する平板材は、板厚0.25mmの「ばね用りん青銅板(C5210)」に機械加工を施すことによって形成されているが、材質や製法を限定するものではない。   Here, the horizontal widths 12w and 13w are directions in which the substrate terminals 100 are adjacent to each other when the plurality of substrate terminals 100 are connected along the periphery of the printed circuit board 200 (arrow X in FIG. 1). Direction). The flat plate material constituting the terminal body 10 is formed by machining a “spring phosphor bronze plate (C5210)” having a thickness of 0.25 mm, but the material and the manufacturing method are not limited.

バネ接触部11は、基板受け部12と略平行をなす支持部材13の下面側において、基板受け部12及び受け側接点部16に向かってV字状をなすように突設され、支持部材13の基端側にはケーブル17を結束するためのケーブル保持部18及びケーブル圧着部19が設けられている。V字状をなすバネ接触部11の内側には、側面視J字状の補助バネ20が設けられている。ケーブル圧着部19は、バネ接触部11及び基板受け部12に対して略直角方向からの加圧によりケーブル17を圧着可能であるように形成されている。   The spring contact portion 11 protrudes in a V shape toward the substrate receiving portion 12 and the receiving side contact portion 16 on the lower surface side of the supporting member 13 that is substantially parallel to the substrate receiving portion 12. A cable holding part 18 and a cable crimping part 19 for bundling the cables 17 are provided on the base end side. An auxiliary spring 20 having a J-shape in a side view is provided inside the spring contact portion 11 having a V shape. The cable crimping portion 19 is formed so that the cable 17 can be crimped to the spring contact portion 11 and the substrate receiving portion 12 by pressurization from a substantially perpendicular direction.

保護壁14は、端子本体10を構成する平板材の一部に加圧加工を施すことによって減厚し、支持部材13の先端下方に位置する折曲部14aにおいて、支持部材13の基端側に向かって180度折り曲げることによって形成されている。折曲部14aは、その稜線方向がプリント回路基板200の平面方向と直交するように形成されている。支持部材13の基端側に位置する保護壁14先端には、断面へ字状をなすように折り曲げて係止部14bが形成されている。また、端子本体10を構成する平板材の一部にコ字状の切り込みを入れて、その内周部分を引き起こして係止片21を形成し、この係止片21の下面側に係止部14bを差し込むことによって、保護壁14の先端部分が端子本体10に係止されている。   The protective wall 14 is reduced in thickness by applying pressure processing to a part of the flat plate material constituting the terminal body 10, and the base end side of the support member 13 in the bent portion 14 a located below the front end of the support member 13. It is formed by bending 180 degrees toward. The bent portion 14 a is formed so that the ridge line direction is orthogonal to the planar direction of the printed circuit board 200. At the distal end of the protective wall 14 positioned on the base end side of the support member 13, a locking portion 14 b is formed by bending the cross section so as to form a letter shape.

The female housing 300 is formed of a synthetic resin material having insulating properties, and the tips of the substrate receiving portions 12 and the support members 13 of the plurality of substrate terminals 100 (see FIG. 1) inserted from the back side to the front side. A plurality of through holes 30 and 31 for holding the portion are formed.

次に、図16〜図21に基づいて、基板用端子100及びこれを用いた基板用コネクタ400について説明する。図16〜図19に示すように、複数の基板用端子100は、雌ハウジング300の背面側からその内部に挿入され、一定間隔に配置された状態となり、これら複数の基板用端子100を、その背面側から雌ハウジング300内に装着されるリテーナ500で固定することによって基板用コネクタ400が形成される。基板用コネクタ400においては、雌ハウジング300の正面に見えている複数の貫通孔30,31内にそれぞれ基板用端子100の支持部材13及び基板受け部12が収容された状態となっている。   Next, the board terminal 100 and the board connector 400 using the board terminal 100 will be described with reference to FIGS. As shown in FIG. 16 to FIG. 19, the plurality of board terminals 100 are inserted into the female housing 300 from the back side thereof and are arranged at regular intervals. The board connector 400 is formed by fixing with a retainer 500 mounted in the female housing 300 from the back side. In the board connector 400, the support member 13 and the board receiving portion 12 of the board terminal 100 are accommodated in the plurality of through holes 30 and 31 that are visible in the front of the female housing 300, respectively.

一方、図19に示すように、雄ハウジング600の背面側には、雄ハウジング600の正面側から挿入されたプリント回路基板200の接触端子部201及び端子受け部202付近が突出し、雌ハウジング300を装着するために略短四角筒形状に形成された接続部60がプリント回路基板200の突出部分を囲むように形成され、接続部60の上部にロックアーム係合部61が設けられている。   On the other hand, as shown in FIG. 19, on the back side of the male housing 600, the contact terminal portion 201 and the vicinity of the terminal receiving portion 202 of the printed circuit board 200 inserted from the front side of the male housing 600 protrude. A connecting portion 60 formed in a substantially short rectangular tube shape for mounting is formed so as to surround the protruding portion of the printed circuit board 200, and a lock arm engaging portion 61 is provided on the upper portion of the connecting portion 60.

図19に示すように、

プリント回路基板200が装着された雄ハウジング600の正面側の接続部61内に、雄ハウジング600の背面側から差し込み、
プリント回路基板200の接触端子部201及び端子受け部202部分を雌ハウジング300の基板挿入口32に挿入するとともに、
図20に示すように、
雌ハウジング300のロックアーム33を雄ハウジング600のロックアーム係合部61に係合させると、
複数の基板用端子100を有する基板用コネクタ400と、プリント回路基板200との接続が完了する。
As shown in FIG.
The front side of the female housing 300 of the board connector 400 formed by mounting a plurality of board terminals 100 is
Inserted into the connecting portion 61 on the front side of the male housing 600 to which the printed circuit board 200 is mounted from the back side of the male housing 600,
While inserting the contact terminal part 201 and the terminal receiving part 202 part of the printed circuit board 200 into the board insertion port 32 of the female housing 300,
As shown in FIG.
When the lock arm 33 of the female housing 300 is engaged with the lock arm engaging portion 61 of the male housing 600,
The connection between the printed circuit board 200 and the board connector 400 having the plurality of board terminals 100 is completed.

図21に示すように、基板用端子100においては、基板受け部12の横幅12wは支持部材13の横幅13wより小さく形成されているため、基板用端子10をその正面側(図1に示すプリント回路基板200側)から見たとき、端子本体10は逆L字形をなしている。従って、図16,図17に示すように、複数の基板用端子100を複数配列する場合、隣り合う基板用端子100のバネ接触部11と基板受け部12とがプリント回路基板200を挟んで交互に位置するように配置すれば、二つの基板用端子10の支持部材13の横幅13wの和より狭いスペース内に、二つの基板用端子100を対向配置することができるため、コネクタの狭ピッチ化を図ることができる。   As shown in FIG. 21, in the board terminal 100, since the lateral width 12w of the board receiving portion 12 is smaller than the lateral width 13w of the support member 13, the board terminal 10 is placed on the front side (the print shown in FIG. 1). When viewed from the circuit board 200 side), the terminal body 10 has an inverted L-shape. Therefore, as shown in FIGS. 16 and 17, when a plurality of substrate terminals 100 are arranged, the spring contact portions 11 and the substrate receiving portions 12 of the adjacent substrate terminals 100 are alternately sandwiched between the printed circuit boards 200. If the two board terminals 100 are arranged opposite to each other in a space narrower than the sum of the lateral widths 13w of the support members 13 of the two board terminals 10, the connector pitch is reduced. Can be achieved.

特に、基板用端子100の場合、端子本体10の基板受け部12の横幅12wをバネ接触部11の支持部材13の横幅13wの半分よりも小さく設定しているので、一つの基板用端子100の支持部材13の横幅13wの範囲内に二つの基板用端子100を配置することができ、狭ピッチ化への適応性に優れている。   In particular, in the case of the board terminal 100, the width 12w of the board receiving portion 12 of the terminal body 10 is set to be smaller than half of the width 13w of the support member 13 of the spring contact portion 11. The two board terminals 100 can be arranged within the range of the lateral width 13w of the support member 13, which is excellent in adaptability to narrow pitch.

基板用端子100においては、平板材の一部を減厚して折り曲げることによりバネ接触部11の側面を覆う保護壁14を形成し、同じく平板材の一部を折り曲げて基板受け部12の凹状領域12a内に嵌め込んで基板受け部保護壁15を設けたことにより、製造工程における生産性及び作業性の向上を図ることができる。   In the substrate terminal 100, a protective wall 14 is formed to cover the side surface of the spring contact portion 11 by thinning and bending a portion of the flat plate material, and a concave shape of the substrate receiving portion 12 is also formed by bending a portion of the flat plate material. By providing the substrate receiving portion protection wall 15 by fitting into the region 12a, it is possible to improve productivity and workability in the manufacturing process.

また、基板用端子100においては、端子本体10を構成する平板材の一部を減厚して折り曲げて保護壁14を形成したことにより、バネ接触部11と保護壁14との隙間を狭隘化して、バネ接触部11付近及び基板受け部12付近の横幅の増大を回避することができるため、基板用コネクタ400の狭ピッチ化に有効である。   Further, in the board terminal 100, a part of the flat plate material constituting the terminal body 10 is reduced in thickness and bent to form the protective wall 14, thereby narrowing the gap between the spring contact portion 11 and the protective wall 14. Thus, an increase in the lateral width in the vicinity of the spring contact portion 11 and in the vicinity of the substrate receiving portion 12 can be avoided, which is effective in narrowing the pitch of the board connector 400.

さらに、保護壁14の係止部14bを端子本体10の係止片21に係止したことにより、端子本体10と保護壁14との一体性が高まり、端子本体10の剛性を増大することに有効である。また、基板受け部12に、基板受け部保護壁15が嵌め込まれる凹状領域12aを設けたことにより、基板受け部12の剛性が増大するので、接触信頼性の向上に有効である。なお、使用条件に応じて、保護壁14を設けない構造とすることもできる。   Furthermore, by locking the locking portion 14b of the protective wall 14 to the locking piece 21 of the terminal main body 10, the integrity of the terminal main body 10 and the protective wall 14 is increased, and the rigidity of the terminal main body 10 is increased. It is valid. In addition, since the substrate receiving portion 12 is provided with the concave region 12a into which the substrate receiving portion protection wall 15 is fitted, the rigidity of the substrate receiving portion 12 is increased, which is effective in improving the contact reliability. In addition, it can also be set as the structure which does not provide the protective wall 14 according to use conditions.

また、端子本体10の基板受け部12は、平板材をその平面方向がプリント回路基板200の平面方向と直交する状態に配置して形成しているため、図21に示すように、基板用端子100をプリント回路基板200に接続したときにバネ接触部11の弾性力によって基板受け部12が受ける押圧力に対する剛性が高く、プリント回路基板200の接触端子部201と端子受け部202に対する安定した接触圧力を発生し、優れた接触信頼性を得ることができる。   In addition, since the board receiving portion 12 of the terminal body 10 is formed by arranging a flat plate so that the plane direction thereof is orthogonal to the plane direction of the printed circuit board 200, as shown in FIG. High rigidity with respect to the pressing force received by the substrate receiving portion 12 by the elastic force of the spring contact portion 11 when the 100 is connected to the printed circuit board 200, and stable contact between the contact terminal portion 201 and the terminal receiving portion 202 of the printed circuit board 200 Pressure can be generated and excellent contact reliability can be obtained.

一方、バネ接触部11の内周側に、当該バネ接触部11を基板受け部12に向かって付勢する補助バネ20を設けたことにより、プリント回路基板200に対する挟持力を強化することができるため、接触信頼性を高めることができる。また、ケーブル圧着部19を支持部材13に対し約90°回転させた状態とすることにより、端子圧着工程などにおける端子本体10のセット高さを低くすることができるため、作業性の向上に有効である。   On the other hand, by providing the auxiliary spring 20 that urges the spring contact portion 11 toward the substrate receiving portion 12 on the inner peripheral side of the spring contact portion 11, the clamping force for the printed circuit board 200 can be strengthened. Therefore, contact reliability can be improved. In addition, by setting the cable crimping portion 19 in a state of being rotated about 90 ° with respect to the support member 13, the set height of the terminal body 10 in the terminal crimping step or the like can be lowered, which is effective in improving workability. It is.

次に、図22〜図24に基づいて、本発明の第2〜4実施形態である基板用端子102,103,104について説明する。なお、基板用端子102,103,104の構成部分において、図1〜図8に示す基板用端子100の構成部分と共通する部分については、図1〜図8中の符号と同じ符号を付して説明を省略する。   Next, the board terminals 102, 103, and 104 according to the second to fourth embodiments of the present invention will be described with reference to FIGS. In the constituent parts of the board terminals 102, 103, 104, the parts common to the constituent parts of the board terminal 100 shown in FIGS. The description is omitted.

図22に示す基板用端子102においては、端子本体101を構成する平板材の一部を減厚して折曲部124aで折り曲げることにより、バネ接触部121の側面を覆う保護壁124が形成され、同じく前記平板材の一部を折曲部125aで折り曲げて、断面形状が略コ字形状をなす基板受け部122の凹状領域122a内に嵌め込むことにより、基板受け部122の側面の一部を覆う基板受け部保護壁125が形成されている。   In the board terminal 102 shown in FIG. 22, a protective wall 124 that covers the side surface of the spring contact portion 121 is formed by reducing the thickness of a part of the flat plate material that constitutes the terminal body 101 and bending it at the bent portion 124 a. Similarly, a part of the side surface of the substrate receiving portion 122 is formed by bending a part of the flat plate material at the bent portion 125a and fitting it into the recessed region 122a of the substrate receiving portion 122 having a substantially U-shaped cross section. A substrate receiving part protective wall 125 is formed to cover the substrate.

図8に示す基板用端子100と、図22に示す基板用端子102と、を対比すると分かるように、基板受け部122の横幅122wをバネ接触部121の支持部材13の横幅13wと同じとするとともに、バネ接触部121の側面を覆う保護壁124の折曲部124aの横幅124wを支持部材13の横幅13wと同じとしている。図22に示す基板用端子102の構造とすれば、端子本体101の剛性をさらに増大させることができるので、複数の基板用端子102を配置して形成される電気コネクタ(図示せず)において、その配列ピッチを比較的広く確保できる場合、個々の端子本体101の剛性を十分に確保することができる。   As can be seen by comparing the board terminal 100 shown in FIG. 8 and the board terminal 102 shown in FIG. 22, the lateral width 122 w of the board receiving portion 122 is the same as the lateral width 13 w of the support member 13 of the spring contact portion 121. In addition, the lateral width 124 w of the bent portion 124 a of the protective wall 124 that covers the side surface of the spring contact portion 121 is the same as the lateral width 13 w of the support member 13. The structure of the board terminal 102 shown in FIG. 22 can further increase the rigidity of the terminal body 101. Therefore, in an electrical connector (not shown) formed by arranging a plurality of board terminals 102, When the arrangement pitch can be secured relatively wide, the rigidity of each terminal body 101 can be sufficiently secured.

次に、図23に示す基板用端子103においては、端子本体105を構成する平板材の一部を折曲部126aで折り曲げて、断面形状が略コ字形状をなす基板受け部127の凹状領域127a内に嵌め込むことにより、基板受け部127の側面の一部を覆う基板受け部保護壁126が形成されている。また、基板受け部保護壁126を基板受け部127に係止する係止手段として、基板受け部127及び基板受け部保護壁126に互いに嵌合する凹凸嵌合構造128が形成されている。   Next, in the substrate terminal 103 shown in FIG. 23, a part of the flat plate material constituting the terminal body 105 is bent at the bent portion 126a, and the concave region of the substrate receiving portion 127 having a substantially U-shaped cross section. A board receiving part protective wall 126 that covers a part of the side surface of the board receiving part 127 is formed by being fitted into the 127 a. Further, as a locking means for locking the substrate receiving portion protective wall 126 to the substrate receiving portion 127, a concave / convex fitting structure 128 that is fitted to the substrate receiving portion 127 and the substrate receiving portion protective wall 126 is formed.

凹凸嵌合構造128は、基板受け部保護壁12の周縁の一部に設けられた凸状部126bを、基板受け部127の凹状領域127aを形成するリブ127cの一部に開設された凹状部127bに嵌合させることによって形成されている。凸状部126bを凹状部127bに嵌合させると、基板受け部127と基板受け部保護壁126との一体性が高まるので、プリント回路基板の周縁(図示せず)をバネ接触部11と基板受け部127との間に挟持したとき、基板受け部127に加わるバネ押圧力の一部を基板受け部保護壁126で受けることが可能となるため、端子本体105の剛性を増大させることができる。   The concave / convex fitting structure 128 has a convex portion 126b provided on a part of the peripheral edge of the substrate receiving portion protection wall 12 and a concave portion formed on a part of the rib 127c forming the concave region 127a of the substrate receiving portion 127. It is formed by fitting to 127b. When the convex portion 126b is fitted to the concave portion 127b, the integrity of the substrate receiving portion 127 and the substrate receiving portion protection wall 126 is enhanced, so that the peripheral edge (not shown) of the printed circuit board is connected to the spring contact portion 11 and the substrate. A part of the spring pressing force applied to the substrate receiving portion 127 can be received by the substrate receiving portion protective wall 126 when sandwiched between the receiving portion 127 and the rigidity of the terminal body 105 can be increased. .

次に、図24に示す基板用端子104においては、端子本体107を構成する平板材の一部を折曲部128aで折り曲げて、断面形状が略コ字形状をなす基板受け部129の凹状領域129a内に嵌め込むことにより、基板受け部129の側面の一部を覆う基板受け部保護壁130が形成されている。また、基板受け部保護壁130を基板受け部129に係止する係止手段として、基板受け部12の凹状領域129a内に嵌め込まれた基板受け部保護壁130の周縁130aの一部を凹状領域129aのリブ129cの内側面に押圧状態で当接させた接触係合構造131が形成されている。   Next, in the substrate terminal 104 shown in FIG. 24, a part of the flat plate material constituting the terminal body 107 is bent at the bent portion 128a, and the concave region of the substrate receiving portion 129 having a substantially U-shaped cross section. A board receiving part protection wall 130 that covers a part of the side surface of the board receiving part 129 is formed by being fitted into the 129 a. Further, as a locking means for locking the substrate receiving part protection wall 130 to the substrate receiving part 129, a part of the peripheral edge 130a of the substrate receiving part protection wall 130 fitted in the recessed area 129a of the substrate receiving part 12 is a recessed area. A contact engagement structure 131 is formed in contact with the inner surface of the rib 129c of 129a in a pressed state.

接触係合構造131の形成方法は限定しないが、本実施形態では、基板受け部129の凹状領域129a内に嵌め込まれた基板受け部保護壁130に開設された貫通孔132及びその近傍に圧潰加工を施し、基板受け部保護壁130がその面方向に広がるように圧延させ、基板受け部保護壁130の周縁130aの一部を凹状領域129aのリブ129cの内側面に押圧状態で当接させることによって接触係合構造131を形成している。   Although the method for forming the contact engagement structure 131 is not limited, in the present embodiment, the through hole 132 formed in the substrate receiving part protection wall 130 fitted in the concave region 129a of the substrate receiving part 129 and the vicinity thereof are crushed. The substrate receiving part protection wall 130 is rolled so as to spread in the surface direction, and a part of the peripheral edge 130a of the substrate receiving part protection wall 130 is brought into contact with the inner side surface of the rib 129c of the concave region 129a in a pressed state. Thus, the contact engagement structure 131 is formed.

接触係合構造131を設けたことにより、基板受け部129と基板受け部保護壁130との一体性が高まるので、プリント回路基板の周縁(図示せず)をバネ接触部11と基板受け部129との間に挟持したとき、基板受け部129に加わるバネ押圧力の一部を基板受け部保護壁130で受けることが可能となるため、端子本体107の剛性を増大させることができる。   By providing the contact engagement structure 131, the integrity of the substrate receiving portion 129 and the substrate receiving portion protection wall 130 is increased, and therefore the peripheral edge (not shown) of the printed circuit board is attached to the spring contact portion 11 and the substrate receiving portion 129. Part of the spring force applied to the substrate receiving portion 129 can be received by the substrate receiving portion protection wall 130, so that the rigidity of the terminal body 107 can be increased.
