以下、図面を参照しながら本発明の好適な実施の形態を詳述する。なお、各図面に示される同一または同等の構成要素、部材等には同一の符号を付し、適宜重複した説明は省略する。また、実施の形態は発明を限定するものではなく例示であり、実施の形態に記述されるすべての特徴やその組み合わせは必ずしも発明の本質的なものであるとは限らない。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. The same or equivalent components, members, etc. shown in the drawings are designated by the same reference numerals, and redundant description will be omitted as appropriate. Moreover, the embodiment is not limited to the invention but is an example, and all the features and combinations thereof described in the embodiment are not necessarily essential to the invention.
図１〜図１４を参照し、本発明の実施の形態に係るコネクタ１の構成を説明する。図１により、コネクタ１の互いに直交する前後、上下、左右の各方向を定義する。前後方向は、線状導体の挿入方向（以下、単に「挿入方向」とも表記）であり、前側は挿入方向の手前側、後側は挿入方向の奥側である。コネクタ１は、例えば、ＬＥＤ照明等に用いられる図示しないＣＯＢ（Chip On Board）基板に実装（固定）される、ＣＯＢ基板へのケーブル接続用のリードソケットである。上下方向は、コネクタ１の実装先となる基板と垂直である。コネクタ１は、本実施の形態ではケーブル規格の１つであるＡＷＧ（American Wire Gauge）の２２〜２４に単線及び撚線の双方で対応するため、線状導体の外径が０．５〜０．９ｍｍまで対応できるように設計される。コネクタ１は、第１端子部材１０と、第２端子部材２０と、ガイド部材３０と、を備える。第１端子部材１０及び第２端子部材２０は、それぞれ板金部品である。ガイド部材３０は、樹脂成形体である。 The configuration of the connector 1 according to the embodiment of the present invention will be described with reference to FIGS. 1 to 14. FIG. 1 defines the front-back, up-down, and left-right directions of the connector 1 orthogonal to each other. The front-rear direction is the insertion direction of the linear conductor (hereinafter, also simply referred to as "insertion direction"), the front side is the front side of the insertion direction, and the rear side is the back side of the insertion direction. The connector 1 is, for example, a lead socket for connecting a cable to a COB board, which is mounted (fixed) on a COB (Chip On Board) board (not shown) used for LED lighting or the like. The vertical direction is perpendicular to the board on which the connector 1 is mounted. In the present embodiment, the connector 1 corresponds to 22 to 24 of the AWG (American Wire Gauge), which is one of the cable standards, with both single wire and stranded wire, so that the outer diameter of the linear conductor is 0.5 to 0. Designed to handle up to 9.9 mm. The connector 1 includes a first terminal member 10, a second terminal member 20, and a guide member 30. The first terminal member 10 and the second terminal member 20 are sheet metal parts, respectively. The guide member 30 is a resin molded body.
第１端子部材１０は、前後方向と垂直な板状金属であり、ガイド部材３０の後部の第１保持部３１に保持される。第１端子部材１０の下端面は、ガイド部材３０の下面よりも下方に位置し、ＣＯＢ基板への実装部となる。第１端子部材１０は、弾性変形しない固定部の例示であり、上端部中央に、第１接点部１１を有する。第１接点部１１は、Ｖ字状ないしＵ字状の切欠部（凹形状）である。図示の例では、第１接点部１１は底部が丸味を帯びたＶ字状であり、Ｖ字の角度は約１００°である。Ｖ字の角度は鈍角であることが望ましい。第１接点部１１の後端のエッジ部は、第１エッジ部１１ａであり、線状導体（図１２の単線５１又は図１３の撚線６１）の外周面に下方から食い込んで保持力を発生する部分である。第１エッジ部１１ａは、Ｖ字状ないしＵ字状であることから、線状導体と少なくとも２点で接触することになる。第１エッジ部１１ａは、線状導体の挿入方向を横切るように延びる。 The first terminal member 10 is a plate-shaped metal perpendicular to the front-rear direction, and is held by the first holding portion 31 at the rear of the guide member 30. The lower end surface of the first terminal member 10 is located below the lower surface of the guide member 30 and serves as a mounting portion on the COB substrate. The first terminal member 10 is an example of a fixed portion that is not elastically deformed, and has a first contact portion 11 at the center of the upper end portion. The first contact portion 11 is a V-shaped or U-shaped notch (concave shape). In the illustrated example, the first contact portion 11 has a V-shape with a rounded bottom, and the V-shaped angle is about 100 °. The V-shaped angle is preferably an obtuse angle. The edge portion at the rear end of the first contact portion 11 is the first edge portion 11a, which bites into the outer peripheral surface of the linear conductor (single wire 51 in FIG. 12 or stranded wire 61 in FIG. 13) from below to generate a holding force. It is the part to do. Since the first edge portion 11a is V-shaped or U-shaped, it comes into contact with the linear conductor at at least two points. The first edge portion 11a extends so as to cross the insertion direction of the linear conductor.
第２端子部材２０は、立設部２１及び板バネ部２３を有する。立設部２１は、前後方向と垂直であり、ガイド部材３０の前部の第２保持部３２に保持される。立設部２１の下端面は、ガイド部材３０の下面よりも下方に位置し、ＣＯＢ基板への実装部となる。立設部２１には、線上導体の入口となる挿入口２２が設けられる。板バネ部２３は、立設部２１の上端部から屈曲してガイド部材３０の上方を通って後方斜め下に延び、ガイド部材３０の円筒状内面部３６の後方に至る。板バネ部２３は、上下方向に弾性変形可能であり、弾性変形して線状導体を第１接点部１１側に押圧する押圧部の例示である。板バネ部２３の後端下部のエッジ部は、第２接点部としての第２エッジ部２４であり、線上導体の外周面に上方から食い込んで保持力を発生する部分である。第２エッジ部２４は、線状導体の挿入方向を横切るように延びる。図９に示すように、第１エッジ部１１ａ及び第２エッジ部２４は、線状導体が挿入されていない状態において、挿入方向（前後方向）における位置が略等しい。これにより、線状導体の曲がりを抑制でき、バランス良く線状導体を保持（挟持）できる。特に撚線６１（図１３）は、単線５１（図１２）と比較して剛性が低いため、第１エッジ部１１ａ及び第２エッジ部２４の前後方向の位置ずれにより曲がりやすいが、第１エッジ部１１ａ及び第２エッジ部２４の前後方向位置を略等しくすることで、線状導体が撚線６１であっても曲がりを抑制してバランス良く保持（挟持）できる。線状導体が挿入された状態における第１エッジ部１１ａ及び第２エッジ部２４の前後方向の位置ずれは、線状導体の外径以内であることが望ましく、位置ずれが大きくならないように、板バネ部２３の長さ及び前後方向に対する角度、立設部２１と板バネ部２３との境界部のＲ部（屈曲部）の位置、Ｒサイズを設定している。これにより、線状導体が挿入された状態における第１エッジ部１１ａ及び第２エッジ部２４による保持（挟持）が確実となる。第１エッジ部１１ａ及び第２エッジ部２４の上下方向の間隔は、０．５ｍｍの単線にも保持力（挟持力）を発生できるように、線状導体が挿入されていない状態において０．５ｍｍより小さく設定される。 The second terminal member 20 has an upright portion 21 and a leaf spring portion 23. The upright portion 21 is perpendicular to the front-rear direction and is held by the second holding portion 32 at the front portion of the guide member 30. The lower end surface of the upright portion 21 is located below the lower surface of the guide member 30, and serves as a mounting portion on the COB substrate. The upright portion 21 is provided with an insertion port 22 that serves as an inlet for the on-line conductor. The leaf spring portion 23 bends from the upper end portion of the upright portion 21 and extends diagonally downward rearward through above the guide member 30 to reach the rear of the cylindrical inner surface portion 36 of the guide member 30. The leaf spring portion 23 is an example of a pressing portion that is elastically deformable in the vertical direction and elastically deforms to press the linear conductor toward the first contact portion 11. The edge portion at the lower part of the rear end of the leaf spring portion 23 is the second edge portion 24 as the second contact portion, and is a portion that bites into the outer peripheral surface of the on-line conductor from above to generate a holding force. The second edge portion 24 extends so as to cross the insertion direction of the linear conductor. As shown in FIG. 9, the positions of the first edge portion 11a and the second edge portion 24 in the insertion direction (front-back direction) are substantially the same in the state where the linear conductor is not inserted. As a result, bending of the linear conductor can be suppressed, and the linear conductor can be held (sandwiched) in a well-balanced manner. In particular, since the stranded wire 61 (FIG. 13) has lower rigidity than the single wire 51 (FIG. 12), it is easy to bend due to the positional deviation of the first edge portion 11a and the second edge portion 24 in the front-rear direction, but the first edge By making the positions of the portion 11a and the second edge portion 24 substantially equal in the front-rear direction, bending can be suppressed and the linear conductor can be held (sandwiched) in a well-balanced manner even if it is a stranded conductor 61. It is desirable that the positional deviation of the first edge portion 11a and the second edge portion 24 in the front-rear direction in the state where the linear conductor is inserted is within the outer diameter of the linear conductor, and the plate is prevented from increasing the positional deviation. The length of the spring portion 23 and the angle with respect to the front-rear direction, the position of the R portion (bent portion) of the boundary portion between the upright portion 21 and the leaf spring portion 23, and the R size are set. As a result, the holding (pinching) by the first edge portion 11a and the second edge portion 24 in the state where the linear conductor is inserted is ensured. The vertical distance between the first edge portion 11a and the second edge portion 24 is 0.5 mm in a state where the linear conductor is not inserted so that a holding force (holding force) can be generated even for a single wire of 0.5 mm. Set smaller.
ガイド部材３０は、第１端子部材１０を保持する第１保持部３１及び第２端子部材２０の立設部２１を保持する第２保持部３２を有すると共に、線状導体をガイドするガイド部３３（図５、図６、図９〜図１１）を有する。ガイド部３３は、第１部分としてのテーパー部３５、第２部分としての円筒状内面部（保持部）３６、及び第３部分としての円筒状内面部３７を有する。テーパー部３５の後側（挿入方向奥側）に円筒状内面部３６が連なり、テーパー部３５の前側（挿入方向手前側）に円筒状内面部３７が連なる。図５及び図６に示すように、ガイド部３３の上部は、円筒状内面部３７の前端部の上部を除き、切り欠かれた形状となっているが、樹脂成形に必要な肉厚を確保できる限り、ガイド部３３の上部は左右に繋がっていてもよい。 The guide member 30 has a first holding portion 31 for holding the first terminal member 10 and a second holding portion 32 for holding the upright portion 21 of the second terminal member 20, and a guide portion 33 for guiding the linear conductor. (FIGS. 5, 6, 6 and 9 to 11). The guide portion 33 has a tapered portion 35 as a first portion, a cylindrical inner surface portion (holding portion) 36 as a second portion, and a cylindrical inner surface portion 37 as a third portion. The cylindrical inner surface portion 36 is connected to the rear side (back side in the insertion direction) of the tapered portion 35, and the cylindrical inner surface portion 37 is connected to the front side (front side in the insertion direction) of the tapered portion 35. As shown in FIGS. 5 and 6, the upper portion of the guide portion 33 has a notched shape except for the upper portion of the front end portion of the cylindrical inner surface portion 37, but the wall thickness required for resin molding is secured. As much as possible, the upper part of the guide portion 33 may be connected to the left and right.
テーパー部３５は、前側から後側に向けて（挿入方向の手前側から奥側に向けて）細くなる（径が小さくなる）部分であり、線状導体が撚線６１（図１３）である場合に、撚線６１がばらけないように集約させるように機能する。テーパー部３５の内面が前後方向に対して成す角度θは、０°＜θ＜４５°であるとよく、好ましくは０°＜θ＜１０°であり、図示の例では８°程度としている。θが４５°より小さくすると、挿入方向の力が上下ないし左右方向に分散されることを抑制し、撚線６１の集約をスムーズにできる。 The tapered portion 35 is a portion that becomes thinner (smaller in diameter) from the front side to the rear side (from the front side to the back side in the insertion direction), and the linear conductor is a stranded wire 61 (FIG. 13). In this case, the stranded wires 61 function to be aggregated so as not to be separated. The angle θ formed by the inner surface of the tapered portion 35 with respect to the front-rear direction is preferably 0 ° <θ <45 °, preferably 0 ° <θ <10 °, and is about 8 ° in the illustrated example. When θ is smaller than 45 °, it is possible to suppress the force in the insertion direction from being dispersed in the vertical or horizontal direction, and to smoothly consolidate the stranded wires 61.
円筒状内面部３６及び円筒状内面部３７は、それぞれ前端部から後端部にかけて内寸（内径）が一定である。円筒状内面部３６はテーパー部３５の後端部と同内寸（同内径）であり、円筒状内面部３７はテーパー部３５の前端部と同内寸（同内径）である。円筒状内面部３６の後側（挿入方向奥側）に、前述の第１エッジ部１１ａ及び第２エッジ部２４が位置する。円筒状内面部３６の前後方向の長さは、第１端子部材１０の厚みの２倍以上であることが好ましく、例えば０．５ｍｍ〜１．０ｍｍとする。円筒状内面部３６の内径は、線径０．８ｍｍの撚線に対応するため、誤差も考慮して例えば０．９ｍｍとする。円筒状内面部３６は、テーパー部３５で集約した撚線６１が再びばらけることを抑制しながら後方にガイドするように機能する。図１等に示すように、円筒状内面部３７の前端部（挿入方向の手前側の端部）は、第１端子部材１０の挿入口２２と同軸的に近接する。図９に示すように、円筒状内面部３７の前端部（ガイド部３３の前端部）の内寸（内径）Ｌ１は、挿入口２２の最も細い部分の内寸（内径）Ｌ２よりも大きい（Ｌ１＞Ｌ２）。例えば、Ｌ１＝１．３ｍｍで、Ｌ２＝１．２ｍｍである。これにより、挿入口２２を通過した撚線６１がガイド部材３０の前面に衝突してばらけることを抑制でき、撚線６１をスムーズにコネクタ１に挿入することができる。 The inner dimensions (inner diameter) of the cylindrical inner surface portion 36 and the cylindrical inner surface portion 37 are constant from the front end portion to the rear end portion, respectively. The cylindrical inner surface portion 36 has the same inner dimension (same inner diameter) as the rear end portion of the tapered portion 35, and the cylindrical inner surface portion 37 has the same inner dimension (same inner diameter) as the front end portion of the tapered portion 35. The first edge portion 11a and the second edge portion 24 described above are located on the rear side (back side in the insertion direction) of the cylindrical inner surface portion 36. The length of the cylindrical inner surface portion 36 in the front-rear direction is preferably twice or more the thickness of the first terminal member 10, and is, for example, 0.5 mm to 1.0 mm. The inner diameter of the cylindrical inner surface portion 36 is set to, for example, 0.9 mm in consideration of an error in order to correspond to a stranded wire having a wire diameter of 0.8 mm. The cylindrical inner surface portion 36 functions to guide the stranded wires 61 gathered by the tapered portion 35 backward while suppressing the loosening again. As shown in FIG. 1 and the like, the front end portion (the end portion on the front side in the insertion direction) of the cylindrical inner surface portion 37 is coaxially close to the insertion port 22 of the first terminal member 10. As shown in FIG. 9, the inner dimension (inner diameter) L1 of the front end portion (front end portion of the guide portion 33) of the cylindrical inner surface portion 37 is larger than the inner dimension (inner diameter) L2 of the thinnest portion of the insertion port 22 (inner diameter). L1> L2). For example, L1 = 1.3 mm and L2 = 1.2 mm. As a result, the stranded wire 61 that has passed through the insertion port 22 can be prevented from colliding with the front surface of the guide member 30 and being separated, and the stranded wire 61 can be smoothly inserted into the connector 1.
図１１に示すように、円筒状内面部３６の後端部（ガイド部３３の奥端部）と、第１接点部１１の凹形状の底部との間に、第１接点部１１の前記底部の方が低くなる第１段差部１３が存在する。また、図１０に示すように、ガイド部３３の奥端部と、第１接点部１１の凹形状の底部以外の部分との間に、第１接点部１１の前記底部以外の部分の方が高くなる第２段差部１５が存在する。第１段差部１３は、撚線６１が円筒状内面部３６から後方に出る際に、第１端子部材１０の前面（第１接点部１１の底部直下）と衝突して外側にばらけることを抑制するように機能する。第２段差部１５は、撚線６１をさらに中央に集約するとともに、撚線６１と第１エッジ部１１ａとの接触の確実性を高めるように機能する。第２段差部１５は、撚線６１の６〜７割程度が第１接点部１１の前面に衝突せずに円筒状内面部３６の後端部から後方に出る程度の高さであるとよい。 As shown in FIG. 11, the bottom portion of the first contact portion 11 is located between the rear end portion of the cylindrical inner surface portion 36 (the back end portion of the guide portion 33) and the concave bottom portion of the first contact portion 11. There is a first stepped portion 13 in which is lower. Further, as shown in FIG. 10, a portion of the first contact portion 11 other than the bottom portion is located between the back end portion of the guide portion 33 and the portion other than the concave bottom portion of the first contact portion 11. There is a second step portion 15 that becomes higher. When the stranded wire 61 exits the cylindrical inner surface portion 36 rearward, the first step portion 13 collides with the front surface of the first terminal member 10 (immediately below the bottom portion of the first contact portion 11) and disperses outward. It works to suppress. The second step portion 15 functions to further consolidate the stranded wire 61 in the center and to increase the certainty of contact between the stranded wire 61 and the first edge portion 11a. It is preferable that the second step portion 15 has a height such that about 60 to 70% of the stranded wire 61 protrudes rearward from the rear end portion of the cylindrical inner surface portion 36 without colliding with the front surface of the first contact portion 11. ..
図１２は、単線ケーブル５０を挿入保持したコネクタ１を後方右上から見た斜視図である。単線ケーブル５０は、導体からなる芯線である単線５１の外周を絶縁被覆５２で覆ったものであり、コネクタ１に挿入される部分は絶縁被覆５２が除去されている。図１３は、撚線ケーブル６０を挿入保持したコネクタ１を後方右上から見た斜視図である。撚線ケーブル６０は、導体からなる芯線である撚線６１の外周を絶縁被覆６２で覆ったものであり、コネクタ１に挿入される部分は絶縁被覆６２が除去されている。単線５１及び撚線６１は、第２端子部材２０の挿入口２２から挿入され、ガイド部材３０の円筒状内面部３７、テーパー部３５、円筒状内面部３６、第１エッジ部１１ａと第２エッジ部２４との間の順に通過し、その際に板バネ部２３を押し上げる。板バネ部２３の弾性力により、単線５１及び撚線６１は、第１エッジ部１１ａと第２エッジ部２４とに保持（挟持）される。 FIG. 12 is a perspective view of the connector 1 in which the single wire cable 50 is inserted and held, as viewed from the rear upper right. In the single wire cable 50, the outer circumference of the single wire 51, which is a core wire made of a conductor, is covered with an insulating coating 52, and the insulating coating 52 is removed from the portion inserted into the connector 1. FIG. 13 is a perspective view of the connector 1 in which the stranded cable 60 is inserted and held, as viewed from the rear upper right. In the stranded cable 60, the outer circumference of the stranded wire 61, which is a core wire made of a conductor, is covered with an insulating coating 62, and the insulating coating 62 is removed from the portion inserted into the connector 1. The single wire 51 and the stranded wire 61 are inserted from the insertion port 22 of the second terminal member 20, and the guide member 30 has a cylindrical inner surface portion 37, a tapered portion 35, a cylindrical inner surface portion 36, a first edge portion 11a, and a second edge. It passes between the portions 24 in this order, and at that time, the leaf spring portion 23 is pushed up. The single wire 51 and the stranded wire 61 are held (sandwiched) between the first edge portion 11a and the second edge portion 24 by the elastic force of the leaf spring portion 23.
図１４は、単線ケーブル５０を挿入保持したコネクタ１の背面図であって、単線５１の外径が互いに異なる４種類の場合を併せて示した背面図である。図１４に示すように、コネクタ１は、単線５１の広範囲の外径に対応できる。図示は省略したが、撚線６１についても、同様に広範囲の外径に対応できる。 FIG. 14 is a rear view of the connector 1 in which the single wire cable 50 is inserted and held, and is a rear view showing four types of cases in which the outer diameters of the single wires 51 are different from each other. As shown in FIG. 14, the connector 1 can handle a wide range of outer diameters of the single wire 51. Although not shown, the stranded wire 61 can also be used for a wide range of outer diameters.
本実施の形態によれば、下記の効果を奏することができる。 According to this embodiment, the following effects can be obtained.
(1) ガイド部材３０が挿入方向奥側に向けて細くなるテーパー部３５を有するため、撚線６１の挿入を進める段階で撚線６１をテーパー部３５によって自然に一定径内に集約することができる。よって、撚線６１の一部が途中で引っ掛かったりコネクタ１の外部に出たりすることを抑制でき、確実かつ信頼性の高い撚線６１の保持及び導通を実現できる。撚線６１は、絶縁被覆６２を剥く際にばらけてしまい（広がってしまい）、一定外径（外形）にならないことがあり、従来は一定外径（外形）にするために被覆剥き後に撚線６１を撚り、必要に応じて予備半田を行うことでばらけるのを防止（外形拡大防止および導通安定化）していたが、本実施の形態では被覆剥き後の撚りや予備半田等を行わなくても、撚線６１のばらけ抑制と安定した導通を実現できる。 (1) Since the guide member 30 has a tapered portion 35 that narrows toward the back side in the insertion direction, the stranded wires 61 can be naturally gathered within a constant diameter by the tapered portion 35 at the stage of advancing the insertion of the stranded wires 61. it can. Therefore, it is possible to prevent a part of the stranded wire 61 from being caught in the middle or coming out of the connector 1, and it is possible to realize reliable and highly reliable holding and conduction of the stranded wire 61. The stranded wire 61 may come apart (spread) when the insulating coating 62 is peeled off and may not have a constant outer diameter (outer shape). Conventionally, the stranded wire 61 is twisted after the coating is peeled off in order to obtain a constant outer diameter (outer shape). The wire 61 was twisted and pre-soldered as necessary to prevent it from loosening (prevention of external expansion and stabilization of conduction), but in the present embodiment, twisting and pre-soldering after stripping the coating are performed. Even without it, it is possible to suppress the loosening of the stranded wire 61 and realize stable conduction.
(2) ガイド部材３０はテーパー部３５の奥側に円筒状内面部３６を有するため、テーパー部３５で集約した撚線６１を円筒状内面部３６により再びばらけることを抑制しながら後方にガイドでき、引っ掛かりや跳ね返りを抑制して確実かつ信頼性の高い撚線６１の保持及び導通を実現できる。 (2) Since the guide member 30 has a cylindrical inner surface portion 36 on the back side of the tapered portion 35, the stranded wires 61 gathered by the tapered portion 35 are guided backward while being suppressed from being loosened again by the cylindrical inner surface portion 36. It is possible to suppress catching and rebounding, and to realize reliable and highly reliable holding and conduction of the stranded wire 61.
(3) 弾性変形する押圧部である板バネ部２３の付勢力（弾性）により線状導体を、弾性変形しない固定部である第１接点部１１（第１エッジ部１１ａ）に対して押し付ける構成のため、第１接点部１１（第１エッジ部１１ａ）が弾性を有する場合と異なり、線状導体を安定的に保持することができる。 (3) A configuration in which a linear conductor is pressed against a first contact portion 11 (first edge portion 11a), which is a fixed portion that is not elastically deformed, by an urging force (elasticity) of a leaf spring portion 23 that is an elastically deformable pressing portion. Therefore, unlike the case where the first contact portion 11 (first edge portion 11a) has elasticity, the linear conductor can be stably held.
(4) 板バネ部２３の第２エッジ部２４と第１端子部材１０の第１エッジ部１１ａとで線状導体を保持（挟持）する構成のため、金属エッジ同士での挟持となり、線状導体が撚線６１である場合も安定的な保持が可能となる。 (4) Since the second edge portion 24 of the leaf spring portion 23 and the first edge portion 11a of the first terminal member 10 hold (sandwich) the linear conductor, the linear conductors are sandwiched between the metal edges and are linear. Stable holding is possible even when the conductor is a stranded wire 61.
(5) 円筒状内面部３７の前端部（ガイド部３３の前端部）の内寸（内径）Ｌ１は、挿入口２２の最も細い部分の内寸（内径）Ｌ２よりも大きい（Ｌ１＞Ｌ２）ため、挿入口２２を通過した撚線６１がガイド部材３０の前面に衝突してばらけることを抑制でき、撚線６１をスムーズにコネクタ１に挿入することができる。 (5) The inner dimension (inner diameter) L1 of the front end portion (front end portion of the guide portion 33) of the cylindrical inner surface portion 37 is larger than the inner dimension (inner diameter) L2 of the thinnest portion of the insertion port 22 (L1> L2). Therefore, it is possible to prevent the stranded wire 61 that has passed through the insertion port 22 from colliding with the front surface of the guide member 30 and being separated, and the stranded wire 61 can be smoothly inserted into the connector 1.
(6) 第１接点部１１は、Ｖ字状ないしＵ字状の切欠部（凹形状）であるため、広い径範囲の線状導体と確実に２点接触でき、確実かつ信頼性の高い撚線６１の保持及び導通を実現できる。 (6) Since the first contact portion 11 has a V-shaped or U-shaped notch (concave shape), it can reliably contact a linear conductor in a wide diameter range at two points, and a reliable and highly reliable twist. The holding and continuity of the wire 61 can be realized.
(7) 線状導体が挿入されていない状態において第１エッジ部１１ａ及び第２エッジ部２４の前後方向位置が略等しいため、線状導体の曲がりを抑制でき、バランス良く線状導体を保持（挟持）できる。特に撚線６１は、単線５１と比較して剛性が低いため、第１エッジ部１１ａ及び第２エッジ部２４の前後方向の位置ずれにより曲がりやすいが、本実施の形態では線状導体が撚線６１であっても曲がりを抑制してバランス良く保持（挟持）できる。 (7) Since the positions of the first edge portion 11a and the second edge portion 24 in the front-rear direction are substantially the same when the linear conductor is not inserted, bending of the linear conductor can be suppressed and the linear conductor is held in a well-balanced manner (7). Can be pinched). In particular, since the stranded wire 61 has lower rigidity than the single wire 51, it is easily bent due to the positional deviation of the first edge portion 11a and the second edge portion 24 in the front-rear direction. However, in the present embodiment, the linear conductor is stranded. Even if it is 61, it can be held (pinched) in a well-balanced manner by suppressing bending.
(8) 円筒状内面部３６の後端部（ガイド部３３の奥端部）と、第１接点部１１の凹形状の底部との間に、第１接点部１１の前記底部の方が低くなる第１段差部１３が存在するため、撚線６１が円筒状内面部３６から後方に出る際に第１端子部材１０の前面（第１接点部１１の底部直下）と衝突して外側にばらけることを抑制できる。 (8) The bottom portion of the first contact portion 11 is lower between the rear end portion of the cylindrical inner surface portion 36 (the back end portion of the guide portion 33) and the concave bottom portion of the first contact portion 11. Since the first step portion 13 is present, when the stranded wire 61 exits the cylindrical inner surface portion 36 rearward, it collides with the front surface of the first terminal member 10 (immediately below the bottom portion of the first contact portion 11) and is separated outward. It is possible to suppress the collision.
(9) ガイド部３３の奥端部と、第１接点部１１の凹形状の底部以外の部分との間に、第１接点部１１の前記底部以外の部分の方が高くなる第２段差部１５が存在するため、撚線６１をさらに中央に集約するとともに、撚線６１と第１エッジ部１１ａとの接触の確実性を高めることができる。 (9) A second step portion in which the portion of the first contact portion 11 other than the bottom portion is higher between the inner end portion of the guide portion 33 and the portion other than the concave bottom portion of the first contact portion 11. Since the presence of 15, the stranded wire 61 can be further concentrated in the center, and the certainty of contact between the stranded wire 61 and the first edge portion 11a can be increased.

In the present embodiment, the lower end portion of the first terminal member 10 and the lower end portion of the standing portion 21 of the second terminal member 20 are connected to each other by the connecting portion 40. The lower surface of the connecting portion 40 serves as a mounting portion on the COB substrate.
