Description

本発明は、メス端子に係り、特に、ビード部と弾性部とで箱状部に挿入されたオス端子のオスタブを挟み込むものに関する。   The present invention relates to a female terminal, and more particularly to a method of sandwiching a male tab of a male terminal inserted into a box-shaped portion between a bead portion and an elastic portion.

従来、図１２で示すようなメス端子３０１が知られている（たとえば、特許文献１、特許文献２参照）。メス端子３０１は、平板状の金属の素材を所定形状に形成した後、この所定形状の素材に所定の曲げ加工を施すことを形成されている。また、メス端子３０１は、ビード部３０３が形成された箱状部３０５を備えている。箱状部３０５の内部には、ビード部３０３と対向した板バネ部（弾性部）３０７が設けられている。そして、箱状部３０５内に挿入されたオス端子のオスタブを、ビード部３０３と板バネ部３０７とで挟み込むことで、メス端子３０１がオス端子に接続されるようになっている。   Conventionally, a female terminal 301 as shown in FIG. 12 is known (see, for example, Patent Document 1 and Patent Document 2). The female terminal 301 is formed by forming a flat metal material into a predetermined shape and then subjecting the predetermined shape material to a predetermined bending process. The female terminal 301 includes a box-shaped portion 305 in which a bead portion 303 is formed. Inside the box-shaped part 305, a leaf spring part (elastic part) 307 facing the bead part 303 is provided. And the female terminal 301 is connected to a male terminal by inserting | pinching the male tab of the male terminal inserted in the box-shaped part 305 with the bead part 303 and the leaf | plate spring part 307. FIG.

なお、ビード部３０３は、図１３で示すように、箱状部３０５の底壁部３０９の幅方向中央部にのみ設けられている（たとえば、特許文献３参照）。   In addition, the bead part 303 is provided only in the center part of the width direction of the bottom wall part 309 of the box-shaped part 305, as shown in FIG. 13 (for example, refer patent document 3).

特開２０００−１５００４１号公報JP 2000-150041 A 特開２００１−２１０４１７号公報JP 2001-210417 A 特開２００１−１１０４９７号公報JP 2001-110497 A

ところで、従来のメス端子３０１では、ビード部３０３が底壁部３０９の幅方向中央部にしか形成されていないので、箱状部３０５に挿入されたオス端子のタブとビード部との接触面積が小さくなり、メス端子３０１とオス端子との間の電気的導通性が悪くなるおそがあるという問題がある。   By the way, in the conventional female terminal 301, since the bead part 303 is formed only in the center part in the width direction of the bottom wall part 309, the contact area between the tab of the male terminal inserted into the box-shaped part 305 and the bead part is small. There is a problem that the electrical continuity between the female terminal 301 and the male terminal is likely to be reduced.

また、従来のメス端子３０１の箱状部３０５は、底壁部３０９の幅方向の両端から一対の側壁部３１１，３１３が立ち上がっているが、ビード部３０３の幅方向の一方の端と一方の側壁部３１１との間が僅かにあいており（空隙３１５が形成されており）、ビード部３０３の幅方向の他方の端と他方の側壁部３１３との間が僅かにあいているので（空隙３１７が形成されているので）、底壁部３０９と側壁部３１１との間の曲げ加工がしずらく、底壁部３０９と側壁部３１３との間の曲げ加工がしずらく、メス端子３０１の製造がしづらいという問題がある。   In addition, the box-shaped portion 305 of the conventional female terminal 301 has a pair of side wall portions 311 and 313 rising from both ends of the bottom wall portion 309 in the width direction. There is a slight gap between the side wall portion 311 (a gap 315 is formed), and a slight gap is provided between the other end in the width direction of the bead portion 303 and the other side wall portion 313 (gap). 317), the bending between the bottom wall 309 and the side wall 311 is difficult, the bending between the bottom wall 309 and the side wall 313 is difficult, and the female terminal 301 There is a problem that it is difficult to manufacture.

本発明は、上記問題点に鑑みてなされたものであり、平板状の導電性素材を所定形状に形成した後、この所定形状の素材に所定の曲げ加工を施すことで形成されたメス端子において、製造し易くオス端子との間の電気的導通性が良好であるメス端子を提供することを目的とする。   The present invention has been made in view of the above problems, and in a female terminal formed by forming a flat conductive material into a predetermined shape and then subjecting the predetermined shape of the material to a predetermined bending process.

本発明の実施形態に係るメス端子１は、たとえば、絶縁性のハウジング（図示せず）の端子収容孔に設置されて使用されるものであり、ハウジングに設置されたメス端子１には、オス端子が接続されるようになっている。メス端子１は、たとえば、小型の端子に属し、後述する矩形状の箱状部３の外形寸法Ｌ１，Ｌ２が数ミリメートル程度になっている（図１参照）。   The female terminal 1 according to the embodiment of the present invention is used by being installed in a terminal receiving hole of an insulating housing (not shown), for example, and the female terminal 1 installed in the housing has a male terminal. The terminal is connected. The female terminal 1 belongs to, for example, a small terminal, and outer dimensions L1 and L2 of a rectangular box-shaped portion 3 described later are about several millimeters (see FIG. 1).

また、メス端子１は、金属等の平板状の導電性素材を所定形状に形成した後、この所定形状の素材５（図７参照）に所定の曲げ加工を施すことで形成されたものであり、箱状部３と、ビード部７と、弾性部（板バネ部）９（図５参照）とを備えて構成されている。   The female terminal 1 is formed by forming a flat conductive material such as metal into a predetermined shape and then subjecting the predetermined shape material 5 (see FIG. 7) to a predetermined bending process. The box-shaped part 3, the bead part 7, and the elastic part (leaf spring part) 9 (see FIG. 5) are configured.

箱状部３は、図４等で示すように、細長い矩形状の第１の平板状部１１と細長い矩形状の第２の平板状部１３と細長い矩形状の第３の平板状部１５と細長い矩形状の第４の平板状部１７とによって矩形な筒状に形成されている。   As shown in FIG. 4 and the like, the box-shaped portion 3 includes an elongated rectangular first flat plate portion 11, an elongated rectangular second flat plate portion 13, and an elongated rectangular third flat plate portion 15. It is formed in the shape of a rectangular cylinder by the elongate rectangular fourth flat plate portion 17.

さらに説明すると、第２の平板状部１３は、第１の平板状部１１に隣接し第１の平板状部１１の幅方向の一方の端から９０°の角度で起立して立ち上がっている。第３の平板状部１５は、第１の平板状部１１に隣接し第１の平板状部１１の幅方向の他方の端から９０°の角度で起立して立ち上がっている。第４の平板状部１７は、第３の平板状部１５に隣接し第３の平板状部１５の幅方向の一方の端から９０°の角度で起立して立ち上がっている。   More specifically, the second flat plate portion 13 is adjacent to the first flat plate portion 11 and stands up at an angle of 90 ° from one end in the width direction of the first flat plate portion 11. The third flat plate portion 15 is adjacent to the first flat plate portion 11 and stands up at an angle of 90 ° from the other end in the width direction of the first flat plate portion 11. The fourth flat plate portion 17 is adjacent to the third flat plate portion 15 and rises up at an angle of 90 ° from one end in the width direction of the third flat plate portion 15.

各平板状部１１，１３，１５，１７の長手方向は、筒状の箱状部３の中心軸の延伸方向と一致しており、各平板状部１１，１３，１５，１７それぞれの幅方向は、箱状部３の中心軸の延伸方向に対して直交している。第１の平板状部１１と第４の平板状部１７とは、お互いが平行になって対向しており、第２の平板状部１３と第３の平板状部１５とは、お互いが平行になって対向している。   The longitudinal directions of the flat plate-like portions 11, 13, 15, and 17 coincide with the extending direction of the central axis of the cylindrical box-like portion 3, and the width directions of the flat plate-like portions 11, 13, 15, and 17 respectively. Is orthogonal to the extending direction of the central axis of the box-shaped part 3. The first flat plate portion 11 and the fourth flat plate portion 17 are opposed to each other in parallel, and the second flat plate portion 13 and the third flat plate portion 15 are parallel to each other. Facing each other.

なお、箱状部３における第２の平板状部１３と第４の平板状部１７との境では第２の平板状部１３と第４の平板状部１７とがお互いにごく僅かに離れている（間隙１９が形成されている）が、第２の平板状部１３と第４の平板状部１７とがお互いに接していてもよい。   Note that the second flat plate portion 13 and the fourth flat plate portion 17 are slightly separated from each other at the boundary between the second flat plate portion 13 and the fourth flat plate portion 17 in the box-shaped portion 3. However, the second flat plate portion 13 and the fourth flat plate portion 17 may be in contact with each other.

ビード部７は、矩形な筒状に形成されている箱状部３の１つの平板状部である第１の平板状部１１の一部をこの厚さ方向で箱状部３の内側に突出させることで形成されている。これにより、ビード部７が箱状部３の一部を構成していると考えられる。   The bead portion 7 projects a part of the first flat plate portion 11 which is one flat plate portion of the box-shaped portion 3 formed in a rectangular cylindrical shape to the inside of the box-shaped portion 3 in this thickness direction. It is formed by letting. Thereby, it is considered that the bead portion 7 constitutes a part of the box-shaped portion 3.

弾性部９は、第２の平板状部１３から箱状部３の内側に片持ち梁の態様で延出しており、箱状部３内に挿入された図示しないオス端子のオスタブを、ビード部７と協同して挟み込むようになっている。   The elastic part 9 extends from the second flat plate-like part 13 to the inside of the box-like part 3 in the form of a cantilever, and a male tab of a male terminal (not shown) inserted into the box-like part 3 is connected to the bead part. 7 in cooperation with.

また、メス端子１では、筒状の箱状部３を形成するときに、所定形状の素材５を所定の部位（第１の平板状部１１と第２の平板状部１３との間、および、第１の平板状部１１と第３の平板状部１５との間）の折り曲げをしやすくするために、ビード部７の幅方向の一端で、第２の平板状部１３が第１の平板状部１１から曲がって立ち上がっており、ビード部７の幅方向の他端で、第３の平板状部１５が第１の平板状部１１から曲がって立ち上がっている。   Further, in the female terminal 1, when the cylindrical box-shaped portion 3 is formed, the material 5 having a predetermined shape is moved to a predetermined portion (between the first flat plate portion 11 and the second flat plate portion 13, and In order to facilitate the bending of the first flat plate portion 11 and the third flat plate portion 15), the second flat plate portion 13 is connected to the first flat plate portion 13 at one end in the width direction of the bead portion 7. The third flat plate portion 15 is bent from the first flat plate portion 11 and rises at the other end in the width direction of the bead portion 7.

すなわち、ビード部７の幅方向の一端のところで、素材５が第１の平板状部１１から曲がり始めている。   That is, the material 5 starts to bend from the first flat plate portion 11 at one end in the width direction of the bead portion 7.

さらに説明すると、第２の平板状部１３と第１の平板状部１１との間には、曲率半径の小さな１／４円弧状の折り曲げ部２１が生成されているが、ビード部７の幅方向の一端が折り曲げ部２１の一端（第１の平板状部１１と接している端；１／４円弧の開始点）と接している。なお、折り曲げ部２１の他端は、第２の平板状部１３と接している。   More specifically, a quarter arc-shaped bent portion 21 having a small curvature radius is generated between the second flat plate portion 13 and the first flat plate portion 11. One end in the direction is in contact with one end of the bent portion 21 (the end in contact with the first flat plate portion 11; the start point of the ¼ arc). The other end of the bent portion 21 is in contact with the second flat plate portion 13.

同様にして、第３の平板状部１５と第１の平板状部１１との間には、曲率半径の小さな１／４円弧状の折り曲げ部２１が生成されている。そして、ビード部７の幅方向の他端に直接つながっている１／４円弧状の折り曲げ部２１を間にして、第１の平板状部１１と第３の平板状部１５とがつながっており、ビード部７の幅方向の他端に直接つながっている１／４円弧状の折り曲げ部２１を間にして、第１の平板状部１１と第３の平板状部１５とがつながっている。   Similarly, a quarter arc-shaped bent portion 21 having a small curvature radius is generated between the third flat plate portion 15 and the first flat plate portion 11. And the 1st flat plate-like part 11 and the 3rd flat plate-like part 15 are connected on the other side of the other end of the width direction of the bead part 7 with the 1/4 arc-shaped bending part 21 in between. The first flat plate portion 11 and the third flat plate portion 15 are connected to each other with a quarter arc-shaped bent portion 21 connected directly to the other end in the width direction of the bead portion 7.

なお、ビード部７の幅方向の端が１／４円弧状の折り曲げ部２１に入り込んでいてもよい。すなわち、ビード部７が形成されているところでは、１／４円弧状の折り曲げ部２１の一部がビード部７によって消滅し、たとえば、１／８円弧状になっていてもよい。   The end in the width direction of the bead portion 7 may enter the bent portion 21 having a ¼ arc shape. In other words, where the bead portion 7 is formed, a part of the ¼ arc-shaped bent portion 21 disappears by the bead portion 7 and may be, for example, a ８ arc shape.

また、メス端子１には、芯線カシメ部２３とシースカシメ部２５とが設けられており（図１〜図３参照）、芯線カシメ部２３よって電線（図示せず）の芯線がメス端子１に接続され、シースカシメ部２５よって電線のシースがメス端子１に支持されるようになっている。   The female terminal 1 is provided with a core wire caulking portion 23 and a sheath caulking portion 25 (see FIGS. 1 to 3), and the core wire caulking portion 23 connects the core wire of an electric wire (not shown) to the female terminal 1. The sheath of the electric wire is supported by the female terminal 1 by the sheath caulking portion 25.

メス端子１では、ビード部７が、第１の平板状部１１の幅方向で、第１の平板状部１１の全幅にわたって形成されている（図４、図１０（ａ）等参照）。   In the female terminal 1, the bead portion 7 is formed across the entire width of the first flat plate portion 11 in the width direction of the first flat plate portion 11 (see FIG. 4, FIG. 10A, etc.).

すなわち、ビード部７の第１の平板状部１１からの突出量が、第１の平板状部１１の幅方向では、幅方向両端部の立ち上がり部を除き、一定になっている。   That is, the protruding amount of the bead portion 7 from the first flat plate portion 11 is constant in the width direction of the first flat plate portion 11 except for the rising portions at both ends in the width direction.

なお、第１の平板状部１１の長手方向では、図５で示すように、ビード部７は、第１の平板状部１１の中間部に形成されている。また、第１の平板状部１１の長手方向での、ビード部７の第１の平板状部１１からの突出量は、両端部２９，３１で大きく中間部３３で小さくなっている。なお、第１の平板状部１１の長手方向での、ビード部７の第１の平板状部１１からの突出量が、図１０（ｂ）で示すように、両端の立ち上がり部を除き一定になっていてもよい。   In the longitudinal direction of the first flat plate portion 11, the bead portion 7 is formed at an intermediate portion of the first flat plate portion 11 as shown in FIG. 5. Further, the protruding amount of the bead portion 7 from the first flat plate portion 11 in the longitudinal direction of the first flat plate portion 11 is large at both end portions 29 and 31 and small at the intermediate portion 33. In addition, the protrusion amount from the 1st flat plate part 11 of the bead part 7 in the longitudinal direction of the 1st flat plate part 11 is constant except for the rising part of both ends, as shown in FIG.10 (b). It may be.

第２の平板状部１３から片持ち梁の態様で突出している弾性部９は、細長い矩形状に形成されている。弾性部９は、第１の平板状部１１と第４の平板状部１７との間に位置しており、弾性部９の厚さ方向は、第１の平板状部１１と第４の平板状部１７の厚さ方向に対して僅かに傾いているかもしくはほぼ一致している。弾性部９の長手方向は、第１の平板状部１１や第４の平板状部１７の長手方向と一致している。   The elastic portion 9 protruding from the second flat plate portion 13 in a cantilever manner is formed in an elongated rectangular shape. The elastic portion 9 is located between the first flat plate portion 11 and the fourth flat plate portion 17, and the thickness direction of the elastic portion 9 is the first flat plate portion 11 and the fourth flat plate portion. The shape portion 17 is slightly inclined or substantially coincident with the thickness direction. The longitudinal direction of the elastic portion 9 coincides with the longitudinal direction of the first flat plate portion 11 and the fourth flat plate portion 17.

弾性部９の幅は、たとえば、ビード部７の幅よりも小さくなっており、幅方向では、ビード部７の中心と弾性部９の中心とがお互いに一致している。また、弾性部９の先端部には、第１の平板状部１１側に円弧状に突出している凸部２７が形成されている。凸部２７は、ビード部７と対向している。さらに説明すると、各平板状部１１，１７や弾性部９の長手方向では、凸部２７は、ビード部７の第１の平板状部１１からの突出量が小さくなっている中間部３３と対向している。   For example, the width of the elastic portion 9 is smaller than the width of the bead portion 7, and the center of the bead portion 7 and the center of the elastic portion 9 coincide with each other in the width direction. Further, a convex portion 27 protruding in an arc shape on the first flat plate portion 11 side is formed at the distal end portion of the elastic portion 9. The convex portion 27 faces the bead portion 7. More specifically, in the longitudinal direction of the flat plate-like portions 11, 17 and the elastic portion 9, the convex portion 27 faces the intermediate portion 33 in which the protruding amount of the bead portion 7 from the first flat plate-like portion 11 is small. doing.

メス端子１の箱状部３内（ビード部７と弾性部９との間）にオス端子のオスタブを挿入すると、このオスタブが、ビード部７と弾性部９と凸部２７とに接触して、ビード部７と弾性部９とで所定の付勢力をもって挟み込まれ、メス端子１にオス端子が接続されるようになっている。   When the male tab of the male terminal is inserted into the box-shaped portion 3 of the female terminal 1 (between the bead portion 7 and the elastic portion 9), the male tab comes into contact with the bead portion 7, the elastic portion 9, and the convex portion 27. The bead portion 7 and the elastic portion 9 are sandwiched with a predetermined urging force so that the male terminal is connected to the female terminal 1.

この接続状態のとき、第１の平板状部１１等の長手方向で、オス端子のオスタブの長手方向の基端部における一方の面が、ビード部７の端部２９に接し、オス端子のオスタブの長手方向の中間部における他方の面が、弾性部９の凸部２７に接し、オス端子のオスタブの長手方向の先端部における一方の面が、ビード部７の端部３１に接するので、３点支持の態様で、安定してオス端子が接続される。   In this connected state, in the longitudinal direction of the first flat plate-like portion 11 and the like, one surface at the proximal end portion in the longitudinal direction of the male tab of the male terminal is in contact with the end portion 29 of the bead portion 7, and the male tab of the male terminal The other surface in the middle portion in the longitudinal direction is in contact with the convex portion 27 of the elastic portion 9, and one surface in the distal end portion in the longitudinal direction of the male tab of the male terminal is in contact with the end portion 31 of the bead portion 7. The male terminal is stably connected in a point support manner.

なお、ビード部７が、図１１（ａ）で示すように、第１の平板状部１１の幅方向で、第１の平板状部１１の全幅にわたって形成されておらず、第１の平板状部１１の中間部で途切れていてもよい。   The bead portion 7 is not formed over the entire width of the first flat plate portion 11 in the width direction of the first flat plate portion 11 as shown in FIG. You may interrupt at the intermediate part of the part 11. FIG.

ビード部７が第１の平板状部１１の幅方向の中間部で途切れている形態では、ビード部７の第１の平板状部１１からの突出量が、幅方向の両端部で最も大きくなっており、幅方向の中間部では「０」になっている。なお、幅方向の中間部での突出量が、「０」ではなく、幅方向両端部の突出量より小さくなっていてもよい。このように構成することで、上述したように、３点支持の態様で、安定してオス端子が接続される。   In the form in which the bead portion 7 is interrupted at the intermediate portion in the width direction of the first flat plate-like portion 11, the protruding amount of the bead portion 7 from the first flat plate-like portion 11 is the largest at both end portions in the width direction. It is “0” in the middle part in the width direction. Note that the amount of protrusion at the intermediate portion in the width direction is not “0” and may be smaller than the amount of protrusion at both ends in the width direction. By comprising in this way, as above-mentioned, a male terminal is stably connected by the aspect of 3 point | piece support.

なお、図１１（ｂ）では、各平板状部１１，１７の長手方向でビード部７の突出量が一定になっているが、図５で示したように、変化していてもよい。   In addition, in FIG.11 (b), although the protrusion amount of the bead part 7 is constant in the longitudinal direction of each flat plate-shaped part 11 and 17, as shown in FIG. 5, you may change.

ところで、ビード部７が、図６で示すように、ビード部７の端で所定形状の素材５に剪断歪（永久歪）を発生させることで形成されていてもよい。図６の参照符号３５で示す箇所は、剪断歪が発生している箇所である。剪断歪のずれ量Ｌ３は、所定形状の素材５の厚さｔ１よりも小さくなっていることが望ましい。   By the way, the bead part 7 may be formed by generating a shear strain (permanent strain) in the material 5 having a predetermined shape at the end of the bead part 7 as shown in FIG. A portion indicated by reference numeral 35 in FIG. 6 is a portion where shear strain is generated. The shear strain deviation L3 is desirably smaller than the thickness t1 of the material 5 having a predetermined shape.

図８、図９に参考例に係るメス端子３５１を示す。参考例に係るメス端子３５１は、従来のメス端子と同様にして、箱状部３５３の第１の平板状部３５５の幅方向の中間部にのみ、ビード部３５７が形成されている。   8 and 9 show a female terminal 351 according to a reference example. In the female terminal 351 according to the reference example, the bead portion 357 is formed only at the intermediate portion in the width direction of the first flat plate portion 355 of the box-shaped portion 353 in the same manner as the conventional female terminal.

これに対して、メス端子１では、ビード部７の幅方向の一端で第２の平板状部１３が第１の平板状部１１から曲がって立ち上がっており、ビード部７の幅方向の他端で第３の平板状部１５が第１の平板状部１１から曲がって立ち上がっているので、ビード部７の幅が従来のものよりも広くなっており、箱状部３内に挿入されたオス端子のオスタブを、弾性部９と幅の広いビード部７とで挟み込むことができ、オス端子との間の電気的導通性が良好になる。   On the other hand, in the female terminal 1, the second flat plate portion 13 is bent up from the first flat plate portion 11 at one end in the width direction of the bead portion 7, and the other end in the width direction of the bead portion 7. Since the third flat plate portion 15 is bent and rises from the first flat plate portion 11, the width of the bead portion 7 is wider than the conventional one, and the male portion inserted into the box-shaped portion 3. The male tab of the terminal can be sandwiched between the elastic portion 9 and the wide bead portion 7, and the electrical conductivity between the male terminal is improved.

また、メス端子１によれば、ビード部７の幅方向の一端で第２の平板状部１３が第１の平板状部１１から曲がって立ち上がっており、ビード部７の幅方向の他端で第３の平板状部１５が第１の平板状部１１から曲がって立ち上がっているので、ビード部７の幅方向の両端が、第１の平板状部１１と第２の平板状部１３との間の折り曲げと第１の平板状部１１と第３の平板状部１５との間の折り曲げをするときにガイドの役目を果たし、所定形状の素材５の曲げ加工がしやすくなる。これにより、メス端子１の製造がしやすくなる。   Further, according to the female terminal 1, the second flat plate portion 13 is bent up from the first flat plate portion 11 at one end in the width direction of the bead portion 7, and the other end in the width direction of the bead portion 7. Since the third flat plate portion 15 is bent and rises from the first flat plate portion 11, both ends in the width direction of the bead portion 7 are formed between the first flat plate portion 11 and the second flat plate portion 13. It serves as a guide when bending between and between the first flat plate portion 11 and the third flat plate portion 15 and facilitates bending of the material 5 having a predetermined shape. Thereby, manufacture of the female terminal 1 becomes easy.

また、メス端子１において、第１の平板状部１１の幅方向で第１の平板状部１１の全幅にわたってビード部７が形成されている構成にすれば、ビード部７とオス端子のオスタブとの接触面積を一層広げることができる。   Further, in the female terminal 1, if the bead portion 7 is formed over the entire width of the first flat plate portion 11 in the width direction of the first flat plate portion 11, the bead portion 7 and the male tab of the male terminal The contact area can be further expanded.
