Description

本発明は、プリント回路基板のスルーホールに繰り返し挿抜可能な接続端子に関するものである。   The present invention relates to a connection terminal that can be repeatedly inserted into and removed from a through hole of a printed circuit board.

プリント回路基板のスルーホールに挿入して、スルーホール内面と電気的接続を得る接続端子としては、例えば特許文献１に記載されているようなプレスフィット端子が公知である。このプレスフィット端子は、端子の先端側（基板挿入側）が、スルーホールを突き抜ける先端挿入部と、スルーホール内面に接触する接触挿入部で構成され、先端挿入部は二股に分かれており、その先端部が先端側へ行くに従い内方に傾斜するように形成されている。したがって、接続端子の先端部の傾斜面がスルーホールの縁部に案内されながら、接続端子がスルーホール内に挿入されるとき、先端挿入部が撓みやすくなるので、スルーホール挿入途中の挿入力を低くできる。また、接触挿入部の挿入完了時には、接触挿入部がスルーホール内面に高い接触荷重で接触して、接続信頼性を確保する。   As a connection terminal that is inserted into a through hole of a printed circuit board to obtain an electrical connection with the inner surface of the through hole, a press-fit terminal as described in Patent Document 1, for example, is known. In this press-fit terminal, the tip end side (board insertion side) of the terminal is composed of a tip insertion portion that penetrates the through hole and a contact insertion portion that contacts the inner surface of the through hole, and the tip insertion portion is divided into two parts. The tip portion is formed so as to be inclined inward as it goes to the tip side. Therefore, when the connecting terminal is inserted into the through-hole while the inclined surface of the tip of the connecting terminal is guided to the edge of the through-hole, the tip-inserting portion is easily bent. Can be lowered. Further, when the insertion of the contact insertion portion is completed, the contact insertion portion comes into contact with the inner surface of the through hole with a high contact load, thereby ensuring connection reliability.

特開２００５−１７４６５４号公報JP 2005-174654 A

従来のプレスフィット端子は、金属角材を金型等により打ち出し、成形することにより製造されるもので、非常に硬いことから、その外接円の直径をスルーホール内径より大きく設定して、スルーホールを削って接続する接続する方式であり、基本的には挿入というより圧入状態で永久接続するものである。つまり、従来のプレスフィット端子は、弾性変形領域を超えた塑性変形領域でスルーホールに圧入されるものであるため、スルーホールに挿入した後、引き抜いてしまうと、再挿入して繰り返し使用することができないものであった。また、プリント回路基板側も、スルーホールが損傷するため、再使用することができなくなる。   A conventional press-fit terminal is manufactured by punching and molding a metal square with a mold or the like, and is very hard. Therefore, the diameter of the circumscribed circle is set larger than the inner diameter of the through hole, and the through hole is formed. This is a method of connecting by shaving, and basically a permanent connection in a press-fit state rather than insertion. In other words, the conventional press-fit terminal is press-fitted into the through hole in the plastic deformation region beyond the elastic deformation region, so if it is pulled out after being inserted into the through hole, it should be reinserted and used repeatedly. It was something that could not be done. Also, the printed circuit board side cannot be reused because the through hole is damaged.

本発明の目的は、以上のような問題点に鑑み、プリント回路基板のスルーホールに繰り返し挿抜可能な接続端子を提供することにある。   In view of the above problems, an object of the present invention is to provide a connection terminal that can be repeatedly inserted into and removed from a through hole of a printed circuit board.

この目的を達成するため本発明に係る接続端子は、プリント回路基板のスルーホールに繰り返し挿抜可能な接続端子であって、
一枚の金属板からの加工により形成された、四角筒部と、その四角筒部の対向する一対の側壁部の先端側から互いに向かい合う状態で先の方へ伸び出す一対の弾性片とを少なくとも有しており、
前記一対の弾性片は、伸び出し方向の中間部が前記スルーホール内面に押し付けられる平行部となっており、この平行部から先が徐々に弾性片の間隔が狭まる先すぼみ部となっていて先端で互いに接触している、ことを特徴とするものである。 In order to achieve this object, the connection terminal according to the present invention is a connection terminal that can be repeatedly inserted into and removed from the through hole of the printed circuit board,
At least a square tube portion formed by processing from a single metal plate and a pair of elastic pieces extending toward the front in a state of facing each other from the front end sides of a pair of opposing side wall portions of the square tube portion Have
The pair of elastic pieces is a parallel part in which the intermediate part in the extending direction is pressed against the inner surface of the through hole, and the tip of the pair of elastic pieces is a tapered part where the distance between the elastic pieces gradually narrows from the parallel part. Are in contact with each other.

本発明に係る接続端子において、前記平行部と四角筒部の間が内側にほぼ弓形に曲がった弓形湾曲部となっていることが好ましい。   In the connection terminal according to the present invention, it is preferable that a space between the parallel portion and the rectangular tube portion is an arcuate curved portion that is bent inwardly in an arcuate shape.

また、本発明に係る接続端子において、前記弓形湾曲部の四角筒部寄りの部分は、前記四角筒部の底板部側に折れ曲がった補強板部を有していて、断面Ｌ字形になっていることが好ましい。   In the connection terminal according to the present invention, the portion of the arcuate curved portion near the square tube portion has a reinforcing plate portion bent toward the bottom plate portion of the square tube portion, and has an L-shaped cross section. It is preferable.

また本発明に係る接続端子において、前記一対の弾性片の平行部は断面円弧状に形成されていることが好ましい。   Moreover, the connection terminal which concerns on this invention WHEREIN: It is preferable that the parallel part of a pair of said elastic piece is formed in cross-sectional arc shape.

本発明に係る接続端子は、互いに向かい合う一対の弾性片の中間の平行部より先が先すぼみ状になっていて先端で互いに接触しており、かつ平行部と四角筒部の間が内側に弓形に湾曲しているため、平行部に互いに接近させる方向の外力が加わると、先すぼみ部と弓形湾曲部が共に弾性変形して、平行部は平行状態のまま間隔が狭まるようになる。このため、プリント回路基板のスルーホールに挿入した場合には、平行部の全長がほぼ均等な接圧でスルーホールの内面に接触することになり、低い接圧でも良好な接触状態を得ることができる。したがって、スルーホール内面との接圧を低く、かつ均等に設定できるため、スルーホールに挿入したときに弾性片が塑性変形することがなく、繰り返し挿抜が可能になると共に、スルーホールを損傷させるおそれも少ない。   The connection terminal according to the present invention has a tapered shape in which the tip is parallel to the middle parallel part of the pair of elastic pieces facing each other, and is in contact with each other at the tip. Therefore, when an external force is applied in the direction in which the parallel portions approach each other, both the tapered portion and the arcuate curved portion are elastically deformed, and the distance between the parallel portions is reduced while being in a parallel state. For this reason, when it is inserted into the through hole of the printed circuit board, the entire length of the parallel part comes into contact with the inner surface of the through hole with a substantially uniform contact pressure, and a good contact state can be obtained even with a low contact pressure. it can. Therefore, since the contact pressure with the inner surface of the through hole can be set low and evenly, the elastic piece does not undergo plastic deformation when inserted into the through hole, and can be repeatedly inserted and removed, and the through hole may be damaged. There are few.

また、一対の弾性片の、弓形湾曲部の四角筒部寄りの部分を、断面Ｌ字形に折り曲げておくと、その部分の剛性が高くなるため、弾性片の伸び出し方向が安定し、互いに向かい合う一対の弾性片がどちらかに傾いたり、ずれたりするのを防止できる。
さらに、弾性片の平行部を断面円弧状に形成しておくと、平行部が弾性変形し難くなるため、平行部の全長をより均等な接圧でスルーホールの内面に接触させることができる。 Also, if the portions of the pair of elastic pieces near the square tube portion of the bow-shaped curved portion are bent into an L-shaped cross section, the rigidity of the portions increases, so that the extending direction of the elastic pieces becomes stable and faces each other. It is possible to prevent the pair of elastic pieces from being inclined or displaced in either direction.
Furthermore, if the parallel portion of the elastic piece is formed in a circular arc shape in cross section, the parallel portion is less likely to be elastically deformed, so that the entire length of the parallel portion can be brought into contact with the inner surface of the through hole with a more uniform contact pressure.

図１及び図２は本発明に係る接続端子の一実施形態を示す。この接続端子１は、一枚の金属板からの打抜き・折り曲げ加工により形成されたもので、図１に示すように後端側から順に、インシュレーションバレル部３、ワイヤーバレル部５、四角筒部７及び一対の弾性片９を一体に有している。インシュレーションバレル部３とワイヤーバレル部５は絶縁電線を圧着する部分である。四角筒部７の上面側には金属板の縁の合せ目１１ができる。インシュレーションバレル部３、ワイヤーバレル部５及び四角筒部７の構成は従来の一般的な接続端子と同様である。   1 and 2 show an embodiment of a connection terminal according to the present invention. This connection terminal 1 is formed by punching and bending from a single metal plate, and as shown in FIG. 1, in order from the rear end side, an insulation barrel portion 3, a wire barrel portion 5, a rectangular tube portion. 7 and a pair of elastic pieces 9 are integrally provided. The insulation barrel part 3 and the wire barrel part 5 are parts for crimping the insulated wires. On the upper surface side of the rectangular tube portion 7, a seam 11 of the edge of the metal plate is formed. The structure of the insulation barrel part 3, the wire barrel part 5, and the square cylinder part 7 is the same as that of the conventional general connection terminal.

この接続端子１の特徴は、一対の弾性片９の構成にある。すなわち、一対の弾性片９は、図２に示すように、四角筒部７の両側壁部の先端側から互いに向かい合う状態で先の方へ伸び出すように形成されている。一対の弾性片９の伸び出し方向の中間部には他の部分より間隔の広い平行部１３が設けられており、この平行部１３より先は徐々に弾性片９の間隔が狭まる先すぼみ部１５となっており、一対の弾性片９は先端１７で互いに接触している。また、弾性片９の平行部１３と四角筒部７の間は、内側に弓形に曲がった弓形湾曲部１９となっている。   The connection terminal 1 is characterized by a configuration of a pair of elastic pieces 9. That is, as shown in FIG. 2, the pair of elastic pieces 9 are formed so as to extend toward the front in a state of facing each other from the front end sides of the both side wall portions of the rectangular tube portion 7. A parallel portion 13 having a wider interval than the other portions is provided at an intermediate portion in the extending direction of the pair of elastic pieces 9, and a tapered portion 15 in which the interval between the elastic pieces 9 gradually narrows beyond the parallel portion 13. The pair of elastic pieces 9 are in contact with each other at the tip 17. Moreover, between the parallel part 13 and the square cylinder part 7 of the elastic piece 9, it becomes the arch-shaped curved part 19 bent in the shape of a bow inside.

一対の弾性片９の平行部１３は、図２（Ｃ）のように、断面円弧状に形成され、曲り難く（弾性変形し難く）なっている。一方、先端側の先すぼみ部１５及び後端側の弓形湾曲部１９は、少なくとも一部の区間が断面平板状に形成されていて、曲がりやすく（弾性変形しやすく）なっている。平行部１３の外面の曲率半径は、プリント回路基板２１のスルーホール２３の内面の曲率半径と同じかそれより若干大きく設定されている。また、平行部１３の外面間隔Ｐは、スルーホール２３の内径Ｄより若干大きく設定されている。例えば、Ｄ＝1.1mmのときはＰ＝1.3mm程度にするとよい。これにより、図２（Ｂ）のように弾性片９をスルーホール２３に挿入したときに、スルーホール２３の内面に押し付けられることになる。   The parallel portion 13 of the pair of elastic pieces 9 is formed in an arc shape in cross section as shown in FIG. 2C, and is difficult to bend (not easily elastically deformed). On the other hand, at least a part of the tip-side tapered portion 15 and the rear-end-side arcuate curved portion 19 is formed in a flat plate shape, and is easily bent (easily elastically deformed). The curvature radius of the outer surface of the parallel portion 13 is set to be the same as or slightly larger than the curvature radius of the inner surface of the through hole 23 of the printed circuit board 21. Further, the outer surface interval P of the parallel portion 13 is set to be slightly larger than the inner diameter D of the through hole 23. For example, when D = 1.1 mm, P = 1.3 mm is preferable. Thus, when the elastic piece 9 is inserted into the through hole 23 as shown in FIG. 2B, it is pressed against the inner surface of the through hole 23.

また、この実施形態では、弾性片９の、弓形湾曲部１９の四角筒部７寄りの部分は、四角筒部７の底板部側に折れ曲がった補強板部２５を有していて、この補強板部２５は、図２において紙面背面側から正面側に向けて立ち上がるような断面Ｌ字形に形成されている。   Further, in this embodiment, the elastic piece 9 has a reinforcing plate portion 25 that is bent toward the bottom plate portion side of the rectangular tube portion 7 at the portion near the rectangular tube portion 7 of the arcuate curved portion 19. The portion 25 is formed in an L-shaped cross section that rises from the back side to the front side in FIG.

この接続端子１は、以上のように構成されているため、中間の平行部１３に互いに接近させる方向の外力が加わると、図３（Ａ）に２点鎖線で示すように、先端側の先すぼみ部１５と後端側の弓形湾曲部１９が共に弾性変形して、中間の平行部１３は平行状態のまま間隔が狭まるようになる。このため、弾性片９を、図２（Ｂ）のようにプリント回路基板２１のスルーホール２３に挿入すると、中間平行部１３の全長がほぼ均等な接圧でスルーホール２３の内面に接触することになり、低い接圧でも良好な接触状態を得ることができる。したがって、スルーホール内面との接圧を低く設定できるため、スルーホールに挿入したときに弾性片９が塑性変形することがなく、繰り返し挿抜が可能になると共に、スルーホールを損傷させるおそれも少ない。   Since this connection terminal 1 is configured as described above, when an external force is applied in the direction in which the intermediate parallel portion 13 is brought close to each other, as shown by a two-dot chain line in FIG. Both the recess 15 and the arcuate curved portion 19 on the rear end side are elastically deformed, and the interval between the intermediate parallel portions 13 is narrowed while being in a parallel state. For this reason, when the elastic piece 9 is inserted into the through hole 23 of the printed circuit board 21 as shown in FIG. 2B, the entire length of the intermediate parallel portion 13 contacts the inner surface of the through hole 23 with a substantially uniform contact pressure. Thus, a good contact state can be obtained even at a low contact pressure. Accordingly, since the contact pressure with the inner surface of the through hole can be set low, the elastic piece 9 is not plastically deformed when inserted into the through hole, and can be repeatedly inserted and removed, and the risk of damaging the through hole is small.

これに対し、図３（Ｂ）に示すように弾性片９の先端が開いているタイプの接続端子では、中間に平行部１３を設けておいても、外力を受けたときに、平行部１３が２点鎖線のように斜めに傾いてしまうため、スルーホールに挿入したときに、平行部１３の全長がほぼ均等な接圧でスルーホール内面に接触することができない。このため、低い接圧では良好な接触状態を得ることができない。   On the other hand, as shown in FIG. 3B, in the connection terminal of the type in which the tip of the elastic piece 9 is open, even when the parallel portion 13 is provided in the middle, when the external force is received, the parallel portion 13 However, when inserted into the through hole, the entire length of the parallel portion 13 cannot contact the inner surface of the through hole with a substantially uniform contact pressure. For this reason, a good contact state cannot be obtained with a low contact pressure.

また、この実施形態では、弾性片９の、弓形湾曲部１９の四角筒部７寄りの部分（弾性片９の付け根の部分）が、断面Ｌ字形に折り曲げられているため、その部分の剛性が高くなり、弾性片９の伸び出し方向が安定し、互いに向かい合う一対の弾性片９がどちらかに傾いたり、ずれたりするのを防止できる。   In this embodiment, the portion of the elastic piece 9 near the square tube portion 7 of the arcuate curved portion 19 (the portion of the base of the elastic piece 9) is bent into an L-shaped cross section. It becomes high, the extension direction of the elastic piece 9 is stabilized, and it is possible to prevent the pair of elastic pieces 9 facing each other from being inclined or displaced.

さらに、弾性片９の中間の平行部１３が断面円弧状に形成されているため、平行部１３が弾性変形し難くなり、平行部１３の全長をより均等な接圧でスルーホール２３の内面に接触させることができる。   Furthermore, since the parallel part 13 in the middle of the elastic piece 9 is formed in an arc shape in cross section, the parallel part 13 becomes difficult to elastically deform, and the entire length of the parallel part 13 is applied to the inner surface of the through hole 23 with a more uniform contact pressure. Can be contacted.

図４は、本発明に係る接続端子の使用状態の一例を示す。この例は、コネクタハウジング２７に上記のように構成された多数の接続端子１を一定の配列で組み込み、プリント回路基板２１の多数のスルーホールに一括して接続する場合である。接続端子１はスルーホール内面との接圧が低いため、このように多数の接続端子１を一括して接続する場合でも、挿抜が可能である。   FIG. 4 shows an example of a usage state of the connection terminal according to the present invention. This example is a case where a large number of connection terminals 1 configured as described above are incorporated in the connector housing 27 in a fixed arrangement and connected to a large number of through holes of the printed circuit board 21 at a time. Since the connection terminal 1 has a low contact pressure with the inner surface of the through hole, the connection terminal 1 can be inserted and removed even when a large number of connection terminals 1 are connected together.
