When the contact portion 18a of the elastic bending portion 18 comes into contact with the portion 6a and is displaced in the elastic displacement direction indicated by the arrow Y in FIG. 7, a load is applied to the side-shaped elastic bending portion 18. At that time, the bead processed portion 18b having a reverse U-shaped cross section serves as a beam with respect to the side-shaped elastic bent portion 18, and the rigidity is increased, so that a necessary contact load can be secured.

また、弾性接触片16は、図6に示す状態から図7に示す状態に変位する。この際、弾性接触片16の弾性屈曲部18の自由端部18cが、電気接続部11の天壁部11cの開口孔11dの後側縁に設けられ、過大変位を防止する過大変位防止片12、及び、側壁部11bに設けられ、下方への変位を規制する支持片を兼ねた過大変位防止片13にそれぞれ当接して、所望の接触荷重で弾性変位(バネ変位)が維持される。   Further, the elastic contact piece 16 is displaced from the state shown in FIG. 6 to the state shown in FIG. At this time, the free end portion 18c of the elastic bending portion 18 of the elastic contact piece 16 is provided at the rear edge of the opening hole 11d of the top wall portion 11c of the electrical connection portion 11 to prevent excessive displacement.

この第2実施形態の端子10Aは、弾性屈曲部18の自由端部18cと四角筒状の電気接続部11の両側壁部11b,11bとの両方に過大変位防止部14,15を設けている点が前記第1実施形態と異なる。尚、他の構成は、前記第1実施形態と同一であるため、同一構成部分に同一符号を付して詳細な説明は省略する。   The terminal 10A according to the second embodiment is provided with excessive displacement prevention portions 14 and 15 on both the free end portion 18c of the elastic bending portion 18 and both side wall portions 11b and 11b of the rectangular cylindrical electrical connection portion 11. This is different from the first embodiment. In addition, since the other structure is the same as that of the said 1st Embodiment, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted.

図8〜図13に示すように、弾性屈曲部18の自由端部18cの両側に過大変位を防止する一対の過大変位防止片(過大変位防止部)14,14をそれぞれ一体突出形成してある。さらに、四角筒状の電気接続部11の両側壁部11b,11bに、弾性変位部17の上方への変位時に弾性屈曲部18の各過大変位防止片14が当接して過大変位を防止する矩形の過大変位防止孔(過大変位防止部)15をそれぞれ形成してある。   As shown in FIGS. 8 to 13, a pair of excessive displacement prevention pieces (excessive displacement preventing portions) 14, 14 for preventing excessive displacement are integrally formed on both sides of the free end portion 18 c of the elastic bending portion 18. It is. Further, the excessive displacement prevention pieces 14 of the elastic bending portion 18 come into contact with both side walls 11b, 11b of the rectangular cylindrical electrical connection portion 11 when the elastic displacement portion 17 is displaced upward to prevent excessive displacement. Each of the rectangular excessive displacement prevention holes (excessive displacement prevention portions) 15 is formed.

以上第2実施形態の端子10Aによれば、図13に示すように、カードエッジコネクタ8の端子収容室8aに端子10を収容し、基板ユニットのコネクタ収容部5に嵌合すると、基板ユニットのコネクタ収容部5のホルダ7の押上突起7aにより端子10の弾性接触片16の弾性変位部17が上方へ持ち上がった状態に変位し、弾性接触片16の弾性屈曲部18の接触部18aが基板6の導電部6aと接触する。   As described above, according to the terminal 10A of the second embodiment, when the terminal 10 is accommodated in the terminal accommodating chamber 8a of the card edge connector 8 and fitted into the connector accommodating portion 5 of the board unit, as shown in FIG. The elastic protrusion 17 a of the elastic contact piece 16 of the terminal 10 is displaced upward by the push-up protrusion 7 a of the holder 7 of the connector housing portion 5, and the contact portion 18 a of the elastic bent portion 18 of the elastic contact piece 16 becomes the substrate 6. In contact with the conductive portion 6a.

即ち、ホルダ7の押上突起7aにより端子10の弾性接触片16の弾性変位部17が上方へ持ち上がった状態に変位して、弾性接触片16の弾性屈曲部18の接触部18aが基板6の導電部6aと接触し、弾性屈曲部18の接触部18aが図13で矢印Yで示す弾性変位方向に変位した際に、側面へ字状の弾性屈曲部18に荷重が加わる。その際、側面へ字状の弾性屈曲部18に対し、断面逆U字状のビード加工部18bが梁の役割をし、剛性が上がるため、必要な接触荷重が確保できる。   That is, the push-up protrusion 7 a of the holder 7 displaces the elastic displacement portion 17 of the elastic contact piece 16 of the terminal 10 upward, and the contact portion 18 a of the elastic bent portion 18 of the elastic contact piece 16 is electrically connected to the substrate 6. When the contact portion 18a of the elastic bending portion 18 comes into contact with the portion 6a and is displaced in the elastic displacement direction indicated by the arrow Y in FIG. 13, a load is applied to the side-shaped elastic bending portion 18. At that time, the bead processed portion 18b having a reverse U-shaped cross section serves as a beam with respect to the side-shaped elastic bent portion 18, and the rigidity is increased, so that a necessary contact load can be secured.

また、弾性接触片16は、図12に示す状態から図13に示す状態に変位する。この際、電気接続部11の両側壁部11b,11bに設けられた各過大変位防止孔15の下縁に、弾性接触片16の弾性屈曲部18の自由端部18cの両側に設けられた各過大変位防止片14が当接して、所望の接触荷重で弾性変位(バネ変位)が維持される。   Further, the elastic contact piece 16 is displaced from the state shown in FIG. 12 to the state shown in FIG. At this time, it was provided on both sides of the free end portion 18c of the elastic bending portion 18 of the elastic contact piece 16 at the lower edge of each excessive displacement prevention hole 15 provided on the both side walls 11b, 11b of the electrical connecting portion 11. Each excessive displacement prevention piece 14 abuts, and an elastic displacement (spring displacement) is maintained with a desired contact load.

このように、ホルダ7の押上突起7aにより弾性接触片16の弾性変位部17が上方へ持ち上げられた際に、弾性接触片16の弾性屈曲部18の自由端部18cの各過大変位防止片14が電気接続部11の両側壁部11b,11bの各過大変位防止孔15の下縁の位置で止まって弾性変位が維持されるため、弾性屈曲部18の接触部18aにより常に所望の接触荷重で基板6の導電部6aとの接触が維持できる。即ち、弾性屈曲部18の自由端部18cの過大変位防止片14が止まる電気接続部11の過大変位防止孔15により、弾性接触片16の基板6の導電部6aと接触する接触部18aの接触荷重を所望の接触荷重に常に保持することができる。   In this way, when the elastic displacement portion 17 of the elastic contact piece 16 is lifted upward by the push-up protrusion 7 a of the holder 7, each excessive displacement prevention piece of the free end portion 18 c of the elastic bent portion 18 of the elastic contact piece 16. 14 stops at the position of the lower edge of each excessive displacement prevention hole 15 on both side walls 11b, 11b of the electrical connecting portion 11, and the elastic displacement is maintained, so that a desired contact is always made by the contact portion 18a of the elastic bent portion 18. Contact with the conductive portion 6a of the substrate 6 can be maintained by the load. That is, the contact portion 18a that contacts the conductive portion 6a of the substrate 6 of the elastic contact piece 16 through the excessive displacement prevention hole 15 of the electrical connection portion 11 where the over displacement prevention piece 14 of the free end portion 18c of the elastic bending portion 18 stops. It is possible to always keep the contact load at the desired contact load.

また、前記第1実施形態の弾性屈曲部18の自由端部18cの下方への変位を規制する支持片を兼ねた過大変位防止片13が不要となるため、その分、構造の簡素化及び低コスト化を図ることができる。   In addition, since the excessive displacement prevention piece 13 that also serves as a support piece for restricting the downward displacement of the free end portion 18c of the elastic bending portion 18 of the first embodiment is not necessary, the structure can be simplified and accordingly. Cost reduction can be achieved.

図14は本発明の第3実施形態の端子を断面で示す斜視図、図15は同端子の断面図、図16(a)は同端子の要部の部分断面図、図16(b)は同要部の他の形態の部分断面図である。   14 is a perspective view showing the terminal of the third embodiment in section, FIG. 15 is a sectional view of the terminal, FIG. 16A is a partial sectional view of the main part of the terminal, and FIG. It is a fragmentary sectional view of the other form of the principal part.

この第3実施形態の端子10Bは、図14〜図16(a),(b)に示すように、基板ユニットのコネクタ収容部(相手部材)5の基板6の導電部6aと接触する弾性接触片16を有した四角筒状の電気接続部11と、この四角筒状の電気接続部11の後側に設けられて被覆電線(電線)Wを接続する電線接続部19と、を備え、弾性接触片16は、四角筒状の電気接続部11の底壁部(下部)11aに間隔Hをあけて配置され、基板ユニットのコネクタ収容部5のホルダ7の押上突起(押上部)7aにより上方へ弾性変形する弾性変位部17と、この弾性変位部17の前端側(一端側)の折曲げ自由端部17aを介して弾性変位部17の後部(他端側)17cの上方まで延びて側面へ字状に折り曲げ形成され、弾性変位部17の上方への変位時に基板ユニットのコネクタ収容部5の基板6の導電部6aと接触する接触部18aを中途に有した弾性変形自在の弾性屈曲部18と、を備えている点は、前記第1実施形態と同様である。   As shown in FIGS. 14 to 16A and 16B, the terminal 10B of the third embodiment is in elastic contact with the conductive portion 6a of the substrate 6 of the connector housing portion (mating member) 5 of the substrate unit. A rectangular tubular electrical connecting portion 11 having a piece 16 and an electrical wire connecting portion 19 provided on the rear side of the rectangular tubular electrical connecting portion 11 to connect a covered electric wire (electric wire) W, and is elastic. The contact piece 16 is disposed on the bottom wall portion (lower portion) 11a of the square cylindrical electrical connecting portion 11 with a gap H, and is moved upward by the push-up protrusion (push-up portion) 7a of the holder 7 of the connector housing portion 5 of the board unit. An elastic displacement portion 17 that is elastically deformed toward the upper side and a rear free end portion 17a on the front end side (one end side) of the elastic displacement portion 17 so as to extend above the rear portion (the other end side) 17c of the elastic displacement portion 17 It is bent and formed in a U-shape, and the elastic displacement portion 17 is changed upward. Similar to the first embodiment in that it includes an elastically deformable elastic bending portion 18 having a contact portion 18a that contacts the conductive portion 6a of the substrate 6 of the connector housing portion 5 of the substrate unit. It is.

ここで、図14〜図16(a),(b)に示すように、弾性接触片16の弾性変位部17の前端側の折曲げ自由端部17aの近傍の弾性変位部17の前側と弾性屈曲部18の前側とを樹脂材(補助材)20で覆ってある。   Here, as shown in FIGS. 14 to 16 (a) and 16 (b), the front side of the elastic displacement portion 17 in the vicinity of the bending free end portion 17a on the front end side of the elastic displacement portion 17 of the elastic contact piece 16 is elastic. The front side of the bent portion 18 is covered with a resin material (auxiliary material) 20.

以上第3実施形態の端子10Bによれば、図16(a)で示すように、弾性接触片16の弾性変位部17の前端側の折曲げ自由端部17aの近傍の弾性変位部17の前側と弾性屈曲部18の前側とを補助材としての樹脂材20で覆うことにより、部品点数を増やすことなく、補助部を追加し、弾性接触片16を撓み難くする。これにより、弾性接触片16の基板ユニットのコネクタ収容部5の基板6の導電部6aと接触する接触部18aの接触荷重を増やすことができる。即ち、弾性変位部17の前側と弾性屈曲部18の前側を覆う樹脂材20が無いと、弾性屈曲部18の接触部18aがより深く沈み込むため、その接触荷重が下がってしまうが、樹脂材20でその自由を抑えてあげることにより、接触荷重を上げる(増やす)ことができる。   As described above, according to the terminal 10B of the third embodiment, as shown in FIG. 16A, the front side of the elastic displacement portion 17 in the vicinity of the bending free end portion 17a on the front end side of the elastic displacement portion 17 of the elastic contact piece 16. And the front side of the elastic bent portion 18 are covered with a resin material 20 as an auxiliary material, so that the auxiliary portion is added without increasing the number of parts, and the elastic contact piece 16 is hardly bent. Thereby, the contact load of the contact part 18a which contacts the electroconductive part 6a of the board | substrate 6 of the connector accommodating part 5 of the board | substrate unit of the elastic contact piece 16 can be increased. That is, if there is no resin material 20 that covers the front side of the elastic displacement portion 17 and the front side of the elastic bending portion 18, the contact portion 18a of the elastic bending portion 18 sinks deeper, so that the contact load decreases. By suppressing the freedom at 20, the contact load can be increased (increased).

このように、弾性接触片16の弾性変位部17の前端側の折曲げ自由端部17aの近傍の弾性変位部17の前側と弾性屈曲部18の前側とを樹脂材20で覆うことにより、弾性接触片16の弾性変位部17の前端側の折曲げ自由端部17aを抑え、基板6の導電部6aに対する弾性接触片16の接触部18aの接触荷重を確保することができる。   In this way, by covering the front side of the elastic displacement portion 17 and the front side of the elastic bending portion 18 in the vicinity of the bending free end portion 17a on the front end side of the elastic displacement portion 17 of the elastic contact piece 16 with the resin material 20, the elastic contact piece 16 is elastic. The bending free end portion 17a on the front end side of the elastic displacement portion 17 of the contact piece 16 can be suppressed, and the contact load of the contact portion 18a of the elastic contact piece 16 on the conductive portion 6a of the substrate 6 can be ensured.

また、図16(b)に示すように、樹脂材20の量を増やすことにより、基板6の導電部6aに対する弾性接触片16の接触部18aの接触荷重をより一段と増やすことができる。   Moreover, as shown in FIG.16 (b), by increasing the quantity of the resin material 20, the contact load of the contact part 18a of the elastic contact piece 16 with respect to the electroconductive part 6a of the board | substrate 6 can be increased further.

このように、樹脂材20の量や長さを調整することにより、基板6の導電部6aに対する弾性接触片16の接触部18aの接触荷重と、電気接続部11の底壁部11aと弾性接触片16の弾性変位部17との間の隙間Hに挿入されるホルダ7の押上突起7aの挿入力とをそれぞれ簡単かつ確実に調整することができる。   In this way, by adjusting the amount and length of the resin material 20, the contact load of the contact portion 18 a of the elastic contact piece 16 with respect to the conductive portion 6 a of the substrate 6 and the elastic contact with the bottom wall portion 11 a of the electrical connection portion 11.

It is a fragmentary sectional view of the other form of the principal part.

この第4実施形態の端子10Cは、図17〜図19(a),(b)に示すように、弾性接触片16の弾性変位部17の前端側(一端側)の折曲げ自由端部17aの近傍の弾性変位部17の前側と弾性屈曲部18の前側とをゴム材(補助材)21で覆ってある点が前記第3実施形態と異なる。尚、他の構成は、前記第3実施形態と同一であるため、同一構成部分に同一符号を付して詳細な説明は省略する。   As shown in FIGS. 17 to 19A and 19B, the terminal 10 </ b> C of the fourth embodiment has a bending free end portion 17 a on the front end side (one end side) of the elastic displacement portion 17 of the elastic contact piece 16. Is different from the third embodiment in that the front side of the elastic displacement portion 17 and the front side of the elastic bending portion 18 in the vicinity of are covered with a rubber material (auxiliary material) 21. In addition, since the other structure is the same as that of the said 3rd Embodiment, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted.

以上第4実施形態の端子10Cによれば、図19(a)で示すように、弾性接触片16の弾性変位部17の前端側の折曲げ自由端部17aの近傍の弾性変位部17の前側と弾性屈曲部18の前側とを補助材としてのゴム材21で覆うことにより、部品点数を増やすことなく、補助部を追加し、弾性接触片16を撓み難くする。これにより、弾性接触片16の基板ユニットのコネクタ収容部5の基板6の導電部6aと接触する接触部18aの接触荷重を増やすことができる。即ち、弾性変位部17の前側と弾性屈曲部18の前側を覆うゴム材21が無いと、弾性屈曲部18の接触部18aがより深く沈み込むため、その接触荷重が下がってしまうが、ゴム材21でその自由を抑えてあげることにより、接触荷重を上げる(増やす)ことができる。   As described above, according to the terminal 10 </ b> C of the fourth embodiment, as shown in FIG. 19A, the front side of the elastic displacement portion 17 in the vicinity of the bending free end portion 17 a on the front end side of the elastic displacement portion 17 of the elastic contact piece 16. By covering the front side of the elastic bending portion 18 with a rubber material 21 as an auxiliary material, the auxiliary portion is added and the elastic contact piece 16 is hardly bent without increasing the number of parts. Thereby, the contact load of the contact part 18a which contacts the electroconductive part 6a of the board | substrate 6 of the connector accommodating part 5 of the board | substrate unit of the elastic contact piece 16 can be increased. That is, if there is no rubber material 21 that covers the front side of the elastic displacement portion 17 and the front side of the elastic bending portion 18, the contact portion 18a of the elastic bending portion 18 sinks deeper, so that the contact load decreases. By suppressing the freedom at 21, the contact load can be increased (increased).

このように、弾性接触片16の弾性変位部17の前端側の折曲げ自由端部17aの近傍の弾性変位部17の前側と弾性屈曲部18の前側とをゴム材21で覆うことにより、弾性接触片16の弾性変位部17の前端側の折曲げ自由端部17aを抑え、基板6の導電部6aに対する弾性接触片16の接触部18aの接触荷重を確保することができる。   Thus, by covering the front side of the elastic displacement portion 17 and the front side of the elastic bending portion 18 in the vicinity of the bending free end portion 17a on the front end side of the elastic displacement portion 17 of the elastic contact piece 16 with the rubber material 21, the elastic contact piece 16 is elastic. The bending free end portion 17a on the front end side of the elastic displacement portion 17 of the contact piece 16 can be suppressed, and the contact load of the contact portion 18a of the elastic contact piece 16 on the conductive portion 6a of the substrate 6 can be ensured.

また、図19(b)に示すように、ゴム材21の量を増やすことにより、基板6の導電部6aに対する弾性接触片16の接触部18aの接触荷重をより一段と増やすことができる。   Moreover, as shown in FIG.19 (b), the contact load of the contact part 18a of the elastic contact piece 16 with respect to the electroconductive part 6a of the board | substrate 6 can be increased further by increasing the quantity of the rubber material 21. FIG.

このように、ゴム材21の量や長さを調整することにより、基板6の導電部6aに対する弾性接触片16の接触部18aの接触荷重と、電気接続部11の底壁部11aと弾性接触片16の弾性変位部17との間の隙間Hに挿入されるホルダ7の押上突起7aの挿入力とをそれぞれ簡単かつ確実に調整することができる。   In this way, by adjusting the amount and length of the rubber material 21, the contact load of the contact portion 18 a of the elastic contact piece 16 with respect to the conductive portion 6 a of the substrate 6 and the elastic contact with the bottom wall portion 11 a of the electrical connection portion 11.

That is, as shown in FIG. 2 2 (a), (b ), both side portions 18d of the cross inverted V-shaped resilient bent portion 18, the angle θ between 18d, is made variable freely 180 degrees from .

以上第5実施形態の端子10Dによれば、図2(a)に示すように、断面逆V字状の弾性屈曲部18の両側部18d,18d間の角度θが狭い場合には、その角度が狭くなる分、基板6の導電部6aと接触する接触部18aが高くなるため、基板6の導電部6aとの接触を高い位置で受け止めることができるようになり、弾性屈曲部18の自由に動ける範囲が減り、接触荷重を増やすことができる。 Above, according to the terminal 10D of the fifth embodiment, as shown in FIG. 2 2 (a), when both side portions 18d of the cross inverted V-shaped resilient bent portion 18, the angle θ between 18d narrow, its Since the contact angle 18a that contacts the conductive portion 6a of the substrate 6 is increased by the narrow angle, the contact with the conductive portion 6a of the substrate 6 can be received at a high position, and the elastic bent portion 18 is free. The range of movement can be reduced and the contact load can be increased.

また、図2(b)に示すように、断面逆V字状の弾性屈曲部18の両側部18d,18d間の角度θが広い場合には、その角度が広くなる分、基板6の導電部6aと接触する接触部18aが低くなるため、基板6の導電部6aとの接触を低い位置で受け止めることができるようになり、弾性屈曲部18の自由に動ける範囲が増え、接触荷重を減らすことができる。 Further, as shown in FIG. 2 2 (b), when both side portions 18d of the cross inverted V-shaped resilient bent portion 18, the angle θ between 18d wide, amount that the angle becomes wider, the conductive substrate 6 Since the contact portion 18a in contact with the portion 6a is lowered, the contact with the conductive portion 6a of the substrate 6 can be received at a low position, the range in which the elastic bending portion 18 can freely move is increased, and the contact load is reduced. be able to.
