An insertion groove 21 for inserting the FPC 60 is recessed in the front portion of the upper surface of the insulator 20. The front surface of the insertion groove 21 and the upper surface of the front portion are open. The rear portion of the insertion groove 21 extends to the inside of the insulator 20 (see FIG. 5). The bottom surface of the rear portion of the insertion groove 21 constitutes a mounting surface 21a on which the bottom surface of the FPC 60, particularly the tip thereof, is mounted. A plurality of mounting grooves 22 extending in the front-rear direction are formed on the rear surface of the insulator 20 (see FIG. 4). The plurality of mounting grooves 22 are formed so as to be spaced apart from each other at predetermined intervals and arranged in the left-right direction. The surface shape of the mounting groove 22 along the rear surface of the insulator 20 is a substantially rectangular shape having a long side in the vertical direction and a short side in the horizontal direction. The lengths of the long and short sides of the mounting groove 22 are slightly smaller than the vertical and horizontal widths of the rear surface of the corresponding contact 30 so that the contact 30 can be press-fitted into the mounting groove 22 and fixed as described later. Is big. The rear portion of each mounting groove 22 penetrates the rear portion of the insulator 20 in the front-rear direction. The front portion of each mounting groove 22 is recessed in the bottom surface of the insertion groove 21. A bottom wall 23 is formed at the lower end of the insulator 20 so as to be continuous with the bottom surface of the mounting groove 22. That is, when the connector 10 is mounted on the circuit board CB, the bottom wall 23 is located between the bottom surface of the mounting groove 22 and the circuit board CB.

インシュレータ２０の左右両側部には、一対の側壁２４が形成される。左右の側壁２４の内側面の前端上部には、閉位置保持突起２５が突設される。インシュレータ２０の左右両側部近傍には、左右の側壁２４のすぐ内側に位置し、かつ、前後方向に延びる金具固定溝２６が形成される。金具固定溝２６の前面は開放している。金具固定溝２６の前部の上下両面も開放している。金具固定溝２６の後部の上下両面及び左右両面はインシュレータ２０によって塞がれている。金具固定溝２６の後端は、インシュレータ２０の後端面にまで及んでいる（図４参照）。 A pair of side walls 24 are formed on both the left and right sides of the insulator 20. A closed position holding protrusion 25 is provided so as to project from the upper part of the front end of the inner surface of the left and right side walls 24. In the vicinity of the left and right side portions of the insulator 20, metal fitting fixing grooves 26 located immediately inside the left and right side walls 24 and extending in the front-rear direction are formed. The front surface of the metal fitting fixing groove 26 is open. Both the upper and lower sides of the front portion of the metal fitting fixing groove 26 are also open. The upper and lower sides and the left and right sides of the rear portion of the metal fitting fixing groove 26 are closed by the insulator 20. The rear end of the metal fitting fixing groove 26 extends to the rear end surface of the insulator 20 (see FIG. 4).

金具固定溝２６より内側に位置する部分の前端部には、抜止部２７がそれぞれ上向きに形成される（図３参照）。抜止部２７の前面２７ａと後面２７ｂとは、前後方向に対して直交する平面により構成される。抜止部２７の上面２７ｃは、前後方向に対して平行な平面により構成される。抜止部２７は、インシュレータ２０の左右両端部にそれぞれ形成される。抜止部２７の後方には、インシュレータ２０を上下方向に貫通する貫通孔２８が、抜止部２７と隣接して形成される。貫通孔２８は、後述するＦＰＣ６０の係合部６３を収容する。貫通孔２８の形状及び大きさは、係合部６３を収容可能であれば、任意の形状及び大きさであってもよい。 At the front end of the portion located inside the metal fitting fixing groove 26, the retaining portion 27 is formed upward, respectively (see FIG. 3). The front surface 27a and the rear surface 27b of the retaining portion 27 are formed by planes orthogonal to the front-rear direction. The upper surface 27c of the retaining portion 27 is formed of a plane parallel to the front-rear direction. The retaining portions 27 are formed on the left and right ends of the insulator 20, respectively. Behind the retaining portion 27, a through hole 28 that penetrates the insulator 20 in the vertical direction is formed adjacent to the retaining portion 27. The through hole 28 accommodates the engaging portion 63 of the FPC 60, which will be described later. The shape and size of the through hole 28 may be any shape and size as long as the engaging portion 63 can be accommodated.

複数のコンタクト３０は、ばね弾性を備えた銅合金（例えばリン青銅、ベリリウム銅、若しくはチタン銅）又はコルソン系銅合金の薄板を順送金型（スタンピング）を用いて図示形状に成形加工したものである（図５参照）。コンタクト３０は、その表面に下地となる下地めっきが形成され、下地めっきの上面の一部に表層めっきが積層される。 The plurality of contacts 30 are formed by molding a thin plate of a copper alloy having spring elasticity (for example, phosphor bronze, beryllium copper, or titanium copper) or a Corson-based copper alloy into the illustrated shape using a progressive mold (stamping). Yes (see Figure 5). A base plating is formed on the surface of the contact 30, and the surface plating is laminated on a part of the upper surface of the base plating.

図５に示すように、コンタクト３０は、側面視略コ字形である。コンタクト３０は、先端に接触突部３２を有する接触アーム３１と、接触アーム３１を支持するアーム支持部３３と、接触アーム３１の直上に位置し下面の先端近傍に支持凹部３５を有する押えアーム３４と、を有する。コンタクト３０は、後端に突設した実装部３６を有する。後述するとおり、コンタクト３０の実装部３６は、はんだ付けにより回路基板ＣＢ上の回路パターンと接続される。 As shown in FIG. 5, the contact 30 has a substantially U-shaped side view. The contact 30 includes a contact arm 31 having a contact protrusion 32 at its tip, an arm support portion 33 that supports the contact arm 31, and a pressing arm 34 that is located directly above the contact arm 31 and has a support recess 35 near the tip of the lower surface. And have. The contact 30 has a mounting portion 36 projecting from the rear end. As will be described later, the mounting portion 36 of the contact 30 is connected to the circuit pattern on the circuit board CB by soldering.

各コンタクト３０は、各取付溝２２に取り付けられることで、インシュレータ２０に支持される。すなわち、各コンタクト３０は、インシュレータ２０の各取付溝２２に対して後方から圧入される。図５に示すように各コンタクト３０を取付溝２２に圧入すると、アーム支持部３３が、インシュレータ２０の底壁２３の上面に支持される。接触アーム３１（接触突部３２）は、挿入溝２１内に位置する。押えアーム３４の上面に突設した係止突起３７は、対応する取付溝２２の上面に食い込む（図５参照）。以上により、コンタクト３０は、取付溝２２に対して固定状態となる。コンタクト３０が取付溝２２に対して固定状態となると、コンタクト３０の表面は、取付溝２２の内面に対して近接又は当接する。実装部３６は、インシュレータ２０の後面より後方に突出する。実装部３６の下面はインシュレータ２０の下面より下方に位置する。 Each contact 30 is supported by the insulator 20 by being attached to each mounting groove 22. That is, each contact 30 is press-fitted into each mounting groove 22 of the insulator 20 from the rear. When each contact 30 is press-fitted into the mounting groove 22 as shown in FIG. 5, the arm support portion 33 is supported on the upper surface of the bottom wall 23 of the insulator 20. The contact arm 31 (contact protrusion 32) is located in the insertion groove 21. The locking projection 37 projecting from the upper surface of the pressing arm 34 bites into the upper surface of the corresponding mounting groove 22 (see FIG. 5). As described above, the contact 30 is in a fixed state with respect to the mounting groove 22. When the contact 30 is fixed to the mounting groove 22, the surface of the contact 30 approaches or comes into contact with the inner surface of the mounting groove 22. The mounting portion 36 projects rearward from the rear surface of the insulator 20. The lower surface of the mounting portion 36 is located below the lower surface of the insulator 20.

左右一対の固定金具４０は金属板のプレス成形品であり、インシュレータ２０の左右両端部に取り付けられる（図３参照）。固定金具４０の上面には、アクチュエータ５０を支持する支持部４１が形成される。固定金具４０の下端部には、側方、すなわち左右方向の外側に向けて、略Ｌ字状の実装部４２が突設される。固定金具４０は、インシュレータ２０に対して前方から圧入することによりインシュレータ２０に固定される。 The pair of left and right fixing brackets 40 are press-molded products of a metal plate, and are attached to both left and right ends of the insulator 20 (see FIG. 3). A support portion 41 for supporting the actuator 50 is formed on the upper surface of the fixing bracket 40. A substantially L-shaped mounting portion 42 is projected from the lower end portion of the fixing bracket 40 toward the side, that is, the outside in the left-right direction. The fixing bracket 40 is fixed to the insulator 20 by press-fitting it into the insulator 20 from the front.

左右方向に延びる板状部材である回転式のアクチュエータ５０は、耐熱性の合成樹脂材料を金属製の成形型を利用して射出成形したものである。左右両側部には側部アーム５１がそれぞれ設けられる。アクチュエータ５０の下端部近傍には、アクチュエータ５０を板厚方向に貫通する複数のアーム挿通用貫通孔５２が左右方向に並べて形成される。各アーム挿通用貫通孔５２の直下には、各アーム挿通用貫通孔５２の下端を塞ぐ回転中心軸５３が形成される（図５参照）。所定の隣り合うアーム挿通用貫通孔５２の間に位置する部分の下端部には、カム部５４が設けられる（図４及び図５参照）。アクチュエータ５０の側部アーム５１の先端には、閉位置保持突起５５が外側に向けて突設される（図３参照）。側部アーム５１の内側には、突起部５６がアクチュエータ５０の内面から突設される。 The rotary actuator 50, which is a plate-shaped member extending in the left-right direction, is an injection-molded heat-resistant synthetic resin material using a metal molding die. Side arms 51 are provided on both the left and right sides. A plurality of arm insertion through holes 52 penetrating the actuator 50 in the plate thickness direction are formed in the vicinity of the lower end portion of the actuator 50 side by side in the left-right direction. Immediately below each arm insertion through hole 52, a rotation center shaft 53 that closes the lower end of each arm insertion through hole 52 is formed (see FIG. 5). A cam portion 54 is provided at the lower end of a portion located between predetermined adjacent arm insertion through holes 52 (see FIGS. 4 and 5). A closed position holding protrusion 55 is projected outward from the tip of the side arm 51 of the actuator 50 (see FIG. 3). A protrusion 56 is projected from the inner surface of the actuator 50 inside the side arm 51.

図１、図３に示すようにインシュレータ２０に対してアクチュエータ５０を略直交させた状態で、対応するコンタクト３０の押えアーム３４が各アーム挿通用貫通孔５２に挿入される。支持凹部３５は、回転中心軸５３に係合する（図５参照）。左右の側部アーム５１の基端部は、左右の固定金具４０の支持部４１に載置される。以上により、アクチュエータ５０は、コンタクト３０及び固定金具４０に対して支持される。 As shown in FIGS. 1 and 3, the holding arm 34 of the corresponding contact 30 is inserted into each arm insertion through hole 52 in a state where the actuator 50 is substantially orthogonal to the insulator 20. The support recess 35 engages with the rotation center shaft 53 (see FIG. 5). The base ends of the left and right side arms 51 are placed on the support 41 of the left and right fixing brackets 40. As described above, the actuator 50 is supported by the contact 30 and the fixing bracket 40.

このように支持部４１によって側部アーム５１の基端部が支持されると、各コンタクト３０の支持凹部３５と対応する回転中心軸５３との係合関係が維持される。従って、アクチュエータ５０は、インシュレータ２０（ＦＰＣ６０の挿脱方向）に対して可動可能である。特に、アクチュエータ５０は、回転中心軸５３回りに回転可能になる。 When the base end portion of the side arm 51 is supported by the support portion 41 in this way, the engagement relationship between the support recess 35 of each contact 30 and the corresponding rotation center shaft 53 is maintained. Therefore, the actuator 50 is movable with respect to the insulator 20 (the insertion / removal direction of the FPC 60). In particular, the actuator 50 becomes rotatable around the rotation center axis 53.

コネクタ１０は、前後方向と略平行な回路基板ＣＢ（図１の仮想線参照）の上面（回路形成面）に対して実装される。具体的には、各コンタクト３０の実装部３６は、回路基板ＣＢ上の回路パターン（図示略）に塗布したはんだペーストに載置される。左右の固定金具４０の実装部４２は、回路基板ＣＢ上の接地パターン（図示略）に塗布したはんだペーストに載置される。リフロー炉等において各はんだペーストを加熱溶融することで、各実装部３６は、上記回路パターンにはんだ付けされる。各実装部４２は、上記接地パターンにはんだ付けされる。結果、コネクタ１０の回路基板ＣＢへの実装が完了する。 The connector 10 is mounted on the upper surface (circuit forming surface) of the circuit board CB (see the virtual line in FIG. 1) which is substantially parallel to the front-rear direction. Specifically, the mounting portion 36 of each contact 30 is placed on the solder paste applied to the circuit pattern (not shown) on the circuit board CB. The mounting portions 42 of the left and right fixing brackets 40 are placed on the solder paste applied to the grounding pattern (not shown) on the circuit board CB. By heating and melting each solder paste in a reflow furnace or the like, each mounting portion 36 is soldered to the above circuit pattern. Each mounting portion 42 is soldered to the grounding pattern. As a result, the mounting of the connector 10 on the circuit board CB is completed.

図１及び図２に示すように、ＦＰＣ６０は、複数の薄膜材を互いに接着して構成した積層構造である。ＦＰＣ６０は、延長方向（前後方向）の先端部を構成しかつその他の部分に比べて硬い端部補強部材６１と、延長方向に沿って直線的に延びかつ端部補強部材６１の下面まで延びる複数の回路パターン６２と、延長方向の先端部において、側縁部から外側に向けて突設された係合部６３と、を備える。係合部６３は、延長方向に直交する方向、すなわち左右方向に突出するように、一対形成される。係合部６３の上面６３ａは、端部補強部材６１の上面と同一平面上に位置するように連続して形成される。 As shown in FIGS. 1 and 2, the FPC 60 has a laminated structure in which a plurality of thin film materials are bonded to each other. The FPC 60 includes an end reinforcing member 61 that constitutes a tip portion in the extension direction (front-back direction) and is harder than other portions, and a plurality of FPC 60s that extend linearly along the extension direction and extend to the lower surface of the end reinforcing member 61. 62, and an engaging portion 63 projecting outward from the side edge portion at the tip end portion in the extension direction. A pair of engaging portions 63 are formed so as to project in a direction orthogonal to the extension direction, that is, in the left-right direction. The upper surface 63a of the engaging portion 63 is continuously formed so as to be located on the same plane as the upper surface of the end reinforcing member 61.

ＦＰＣ６０（接続対象物）を接続するためには、アクチュエータ５０を開位置まで回転させる。アクチュエータ５０を開位置まで回転させた後に、挿入溝２１に対してＦＰＣ６０の後端部を前斜め上方から挿入する。アクチュエータ５０を閉位置まで前方に回転させると、側部アーム５１の固定金具４０側の面が支持部４１に接触する。アクチュエータ５０の閉位置保持突起５５は、インシュレータ２０の閉位置保持突起２５と係合する。これにより、アクチュエータ５０は、インシュレータ２０に対して閉位置で保持される。この時、アクチュエータ５０の各カム部５４は、ＦＰＣ６０の上面に対して面接触して、ＦＰＣ６０を下方に押圧する。従って、ＦＰＣ６０の回路パターン６２は、各コンタクト３０の接触アーム３１を下方に弾性変形させながら接触突部３２に対して確実に接触する（図７参照）。 In order to connect the FPC 60 (object to be connected), the actuator 50 is rotated to the open position. After rotating the actuator 50 to the open position, the rear end portion of the FPC 60 is inserted into the insertion groove 21 from diagonally above the front. When the actuator 50 is rotated forward to the closed position, the surface of the side arm 51 on the fixing bracket 40 side comes into contact with the support portion 41. The closed position holding protrusion 55 of the actuator 50 engages with the closed position holding protrusion 25 of the insulator 20. As a result, the actuator 50 is held in the closed position with respect to the insulator 20. At this time, each cam portion 54 of the actuator 50 comes into surface contact with the upper surface of the FPC 60 and presses the FPC 60 downward. Therefore, the circuit pattern 62 of the FPC 60 reliably contacts the contact protrusion 32 while elastically deforming the contact arm 31 of each contact 30 (see FIG. 7).

ＦＰＣ６０を挿入してアクチュエータ５０を開位置から閉位置まで回転した状態における、コネクタ１０とＦＰＣ６０との係合の様子について、図８乃至図１１を用いてより詳細に説明する。図８は、ＦＰＣ６０を挿入した状態でアクチュエータ５０が開位置にあるときの図６に対応する断面図である。図９は、ＦＰＣ６０を挿入した状態でアクチュエータ５０が開位置にあるときの図１のIX−IX矢線に沿った拡大断面図に対応する図である。図１０は、ＦＰＣ６０を挿入した状態でアクチュエータ５０を閉位置まで回転させたときの図８に対応する断面図である。図１１は、ＦＰＣ６０を挿入した状態でアクチュエータ５０を閉位置まで回転させたときの図９に対応する拡大断面図である。 The state of engagement between the connector 10 and the FPC 60 in a state where the FPC 60 is inserted and the actuator 50 is rotated from the open position to the closed position will be described in more detail with reference to FIGS. 8 to 11. FIG. 8 is a cross-sectional view corresponding to FIG. 6 when the actuator 50 is in the open position with the FPC 60 inserted. FIG. 9 is a view corresponding to an enlarged cross-sectional view taken along the IX-IX arrow line of FIG. 1 when the actuator 50 is in the open position with the FPC 60 inserted. FIG. 10 is a cross-sectional view corresponding to FIG. 8 when the actuator 50 is rotated to the closed position with the FPC 60 inserted. FIG. 11 is an enlarged cross-sectional view corresponding to FIG. 9 when the actuator 50 is rotated to the closed position with the FPC 60 inserted.

ＦＰＣ６０がインシュレータ２０の挿入溝２１に挿入されると、ＦＰＣ６０の係合部６３は、インシュレータ２０の対応する位置に形成された貫通孔２８内にそれぞれ収容される（図８参照）。貫通孔２８は、ＦＰＣ６０の載置面２１ａよりも閉じ方向側に係合部６３を収容可能である。この状態で、インシュレータ２０の抜止部２７は、ＦＰＣ６０の抜去方向側、すなわち前側から係合部６３と対向する。抜止部２７は、係合部６３と係合する。アクチュエータ５０が開位置にある状態では、係合部６３の上面６３ａと抜止部２７の上面２７ｃとは、略同一の上下方向位置に配置される。 When the FPC 60 is inserted into the insertion groove 21 of the insulator 20, the engaging portion 63 of the FPC 60 is accommodated in the through hole 28 formed at the corresponding position of the insulator 20 (see FIG. 8). The through hole 28 can accommodate the engaging portion 63 on the closing direction side of the mounting surface 21a of the FPC 60. In this state, the retaining portion 27 of the insulator 20 faces the engaging portion 63 from the extraction direction side of the FPC 60, that is, from the front side. The retaining portion 27 engages with the engaging portion 63. When the actuator 50 is in the open position, the upper surface 63a of the engaging portion 63 and the upper surface 27c of the retaining portion 27 are arranged at substantially the same vertical position.

アクチュエータ５０を閉位置まで回転させると、アクチュエータ５０の突起部５６が、ＦＰＣ６０の係合部６３と当接する。特に、突起部５６は、アクチュエータ５０の閉位置において、係合部６３をアクチュエータ５０の閉じ方向に押し下げる（図１０及び図１１参照）。すなわち、突起部５６は、インシュレータ２０の挿入溝２１に挿入されたＦＰＣ６０の係合部６３の挿入位置に対応して形成される。図１１に示すとおり、突起部５６の左右方向に沿った断面形状は、閉じ方向側、すなわち下方に向けてテーパ状となる。特に、突起部５６の断面形状は、略台形である。突起部５６の先端、すなわち最下部は、閉位置において、抜止部２７の上面２７ｃよりも閉じ方向側（下方）に位置する。すなわち、図１０に示すとおり、閉位置において、突起部５６の最下部は、貫通孔２８内に収容される。 When the actuator 50 is rotated to the closed position, the protrusion 56 of the actuator 50 comes into contact with the engaging portion 63 of the FPC 60. In particular, the protrusion 56 pushes down the engaging portion 63 in the closing direction of the actuator 50 at the closing position of the actuator 50 (see FIGS. 10 and 11). That is, the protrusion 56 is formed corresponding to the insertion position of the engagement portion 63 of the FPC 60 inserted into the insertion groove 21 of the insulator 20. As shown in FIG. 11, the cross-sectional shape of the protrusion 56 along the left-right direction is tapered toward the closing direction side, that is, downward. In particular, the cross-sectional shape of the protrusion 56 is substantially trapezoidal. The tip, that is, the lowermost portion of the protrusion 56 is located in the closing position on the closing direction side (lower side) of the upper surface 27c of the retaining portion 27. That is, as shown in FIG. 10, in the closed position, the lowermost portion of the protrusion 56 is housed in the through hole 28.

アクチュエータ５０が閉位置にある状態では、係合部６３の上面６３ａは、突起部５６によって閉じ方向に押し下げられた分、抜止部２７の上面２７ｃよりも下方に位置する（図１０及び図１１参照）。係合部６３は、突起部５６による閉じ方向への押し下げによって撓み、外側に向かうほど抜止部２７の上面２７ｃから下方へと離間する。 When the actuator 50 is in the closed position, the upper surface 63a of the engaging portion 63 is located below the upper surface 27c of the retaining portion 27 by the amount pushed down in the closing direction by the protrusion 56 (see FIGS. 10 and 11). ). The engaging portion 63 is bent by being pushed down by the protrusion 56 in the closing direction, and is separated downward from the upper surface 27c of the retaining portion 27 toward the outside.

以上のような一実施形態に係るコネクタ１０は、低背化した状態であっても薄型化したＦＰＣ６０の保持力を安定的に維持できる。すなわち、ＦＰＣ６０の薄型化に伴って係合部６３の剛性が低下し、撓みやすくなった場合であっても、突起部５６と係合部６３との当接によって、係り代が安定する。突起部５６による係合部６３の閉じ方向への押し下げによって、係合部６３は下方へと撓む。これにより、係合部６３と抜止部２７との係り代が増す。このように、コネクタ１０は、係合部６３も含めて載置面２１ａに平坦にＦＰＣ６０を載置した場合と比較して、高い保持力を得ることができる。 The connector 10 according to the above embodiment can stably maintain the holding force of the thinned FPC 60 even in a low profile state. That is, even when the rigidity of the engaging portion 63 decreases as the FPC 60 becomes thinner and it becomes easier to bend, the engagement margin is stabilized by the contact between the protruding portion 56 and the engaging portion 63. By pushing down the engaging portion 63 in the closing direction by the protruding portion 56, the engaging portion 63 bends downward. As a result, the engagement margin between the engaging portion 63 and the retaining portion 27 increases. As described above, the connector 10 can obtain a higher holding force as compared with the case where the FPC 60 is mounted flat on the mounting surface 21a including the engaging portion 63.

コネクタ１０は、インシュレータ２０に対して下方に貫通孔２８を設けて係り代を増大させているため、抜止部２７の底壁２３からの突出量を増大させる必要はない。従って、コネクタ１０は、ＦＰＣ６０の挿入時に、ＦＰＣ６０と抜止部２７との接触を防止して、ＦＰＣ６０の挿入性を維持できる。 Since the connector 10 is provided with a through hole 28 below the insulator 20 to increase the engagement margin, it is not necessary to increase the amount of protrusion of the retaining portion 27 from the bottom wall 23. Therefore, the connector 10 can prevent the FPC 60 from coming into contact with the retaining portion 27 when the FPC 60 is inserted, and can maintain the insertability of the FPC 60.

ＦＰＣ６０の挿入時に係合部６３の上面６３ａと抜止部２７の上面２７ｃとが略同一の上下方向位置に配置される場合に、突起部５６の最下部が、閉位置において、抜止部２７の上面２７ｃよりも閉じ方向側に位置する。これにより、突起部５６は、閉位置において、係合部６３を確実に撓ませる。従って、コネクタ１０は、底壁２３からの抜止部２７の突出量を不必要に増大させることなく、係合部６３と抜止部２７との係り代を確保することができる。これにより、コネクタ１０は、保持力を維持できる。 When the upper surface 63a of the engaging portion 63 and the upper surface 27c of the retaining portion 27 are arranged at substantially the same vertical position when the FPC 60 is inserted, the lowermost portion of the protruding portion 56 is the upper surface of the retaining portion 27 in the closed position. It is located closer to the closing direction than 27c. As a result, the protrusion 56 reliably bends the engaging portion 63 in the closed position. Therefore, the connector 10 can secure the engagement margin between the engaging portion 63 and the retaining portion 27 without unnecessarily increasing the amount of protrusion of the retaining portion 27 from the bottom wall 23. As a result, the connector 10 can maintain the holding force.

本発明は、その精神又はその本質的な特徴から離れることなく、上述した実施形態以外の他の所定の形態で実現できることは当業者にとって明白である。従って、先の記述は例示的なものであり、これに限定されるものではない。発明の範囲は、先の記述によってではなく、付加した請求項によって定義される。あらゆる変更のうちその均等の範囲内にあるいくつかの変更は、その中に包含されるものとする。 It will be apparent to those skilled in the art that the present invention can be realized in certain forms other than those described above without departing from its spirit or its essential features. Therefore, the above description is exemplary and is not limited thereto. The scope of the invention is defined by the appended claims, not by the earlier description. Some of all changes that are within their equality shall be included therein.

例えば、図１１に示すとおり、突起部５６のアクチュエータ５０の長手方向に沿った断面形状は、テーパ状、特に略台形であるものとして説明したが、これに限定されない。突起部５６の断面形状は、矩形又は半円形など、ＦＰＣ６０の係合部６３を閉じ方向に押し下げることができる形状であれば任意の形状であってよい。また、突起部５６は、略台形以外のテーパ状の断面を有してもよい。例えば、突起部５６は、係合部６３を閉じ方向に押し下げる量が外側に向かうほど大きくなるような断面形状により構成されてもよい。一例として、突起部５６の断面形状は、アクチュエータ５０の内面からの突設量が左右方向の外側に向かうほど増大するように、直線状の傾斜面を閉じ方向側に有する三角形であってもよい。このような突起部５６の断面形状により、突起部５６は、左右方向の断面視において、内側から外側まで略均一に係合部６３を押圧する。従って、コネクタ１０は、係合部６３の一部に極度の押圧を加えることなく、より自然に係合部６３を撓ませることができる。 For example, as shown in FIG. 11, the cross-sectional shape of the protrusion 56 along the longitudinal direction of the actuator 50 has been described as being tapered, particularly substantially trapezoidal, but is not limited thereto. The cross-sectional shape of the protrusion 56 may be any shape as long as it can push down the engaging portion 63 of the FPC 60 in the closing direction, such as a rectangle or a semicircle. Further, the protrusion 56 may have a tapered cross section other than a substantially trapezoidal shape. For example, the protrusion 56 may be configured to have a cross-sectional shape such that the amount of pushing down the engaging portion 63 in the closing direction increases toward the outside. As an example, the cross-sectional shape of the protrusion 56 may be a triangle having a linear inclined surface on the closing direction side so that the amount of protrusion from the inner surface of the actuator 50 increases toward the outside in the left-right direction. .. Due to the cross-sectional shape of the protrusion 56, the protrusion 56 presses the engaging portion 63 substantially uniformly from the inside to the outside in the cross-sectional view in the left-right direction. Therefore, the connector 10 can flex the engaging portion 63 more naturally without applying extreme pressure to a part of the engaging portion 63.

図１２は、変形例に係るコネクタ１０の図６に対応する断面を示した図である。コネクタ１０は、閉位置におけるアクチュエータ５０の突起部５６と対応する位置に、インシュレータ２０の貫通孔２８を有するものとして説明したが、これに限定されない。図１２に示すとおり、コネクタ１０は、貫通孔２８に代えて、凹部２９を有してもよい。凹部２９の形状及び大きさは、係合部６３を収容可能であれば、任意の形状及び大きさであってもよい。凹部２９は、突起部５６による係合部６３の閉じ方向への押し込みが可能であれば、任意の深さで凹設されてもよい。 FIG. 12 is a view showing a cross section corresponding to FIG. 6 of the connector 10 according to the modified example. Although the connector 10 has been described as having the through hole 28 of the insulator 20 at a position corresponding to the protrusion 56 of the actuator 50 in the closed position, the connector 10 is not limited thereto. As shown in FIG. 12, the connector 10 may have a recess 29 instead of the through hole 28. The shape and size of the recess 29 may be any shape and size as long as the engaging portion 63 can be accommodated. The recess 29 may be recessed at any depth as long as the engaging portion 63 can be pushed in the closing direction by the protrusion 56.

コネクタ１０は、貫通孔２８及び凹部２９のいずれも有さず、係合部６３よりも外側にはインシュレータ２０が形成されないように構成されてもよい。例えば、インシュレータ２０の側壁２４及び金具固定溝２６を省略して、当該構成部に対応する位置にインシュレータ２０が形成されなくてもよい。すなわち、ＦＰＣ６０の側縁部よりも外側には、インシュレータ２０の抜止部２７のみが存在するように、インシュレータ２０が形成されてもよい。 The connector 10 may be configured so that neither the through hole 28 nor the recess 29 is provided, and the insulator 20 is not formed outside the engaging portion 63. For example, the side wall 24 of the insulator 20 and the metal fitting fixing groove 26 may be omitted, and the insulator 20 may not be formed at a position corresponding to the component. That is, the insulator 20 may be formed so that only the retaining portion 27 of the insulator 20 exists outside the side edge portion of the FPC 60.

突起部５６の最下部は、閉位置において、抜止部２７の上面２７ｃよりも閉じ方向側に位置するものとして説明したが、これに限定されない。突起部５６の最下部は、係合部６３を押し下げて、抜止部２７との係り代を確保することが可能であれば、任意の位置に配置されてもよい。例えば、突起部５６の最下部は、閉位置において、抜止部２７の上面２７ｃと略同一の高さに位置してもよい。この場合、突起部５６は、ＦＰＣ６０が挿入されてアクチュエータ５０が開位置にある状態で、抜止部２７の上面２７ｃよりもわずかに上方に位置する係合部６３の上面６３ａを押し下げるように構成される。 The lowermost portion of the protruding portion 56 has been described as being located on the closing direction side of the upper surface 27c of the retaining portion 27 at the closed position, but the present invention is not limited to this. The lowermost portion of the protruding portion 56 may be arranged at an arbitrary position as long as it is possible to push down the engaging portion 63 and secure a gap with the retaining portion 27. For example, the lowermost portion of the protrusion 56 may be located at substantially the same height as the upper surface 27c of the retaining portion 27 in the closed position. In this case, the protrusion 56 is configured to push down the upper surface 63a of the engaging portion 63 located slightly above the upper surface 27c of the retaining portion 27 with the FPC 60 inserted and the actuator 50 in the open position. To.

インシュレータ２０の抜止部２７は、前後方向に対して垂直な前面２７ａ及び後面２７ｂ、並びに前後方向に対して平行な上面２７ｃにより、略直方体状に形成されるものとして説明したが、これに限定されない。抜止部２７は、前面２７ａの上縁部から連続して形成される前側傾斜面及び後面２７ｂの上縁部から連続して形成される後側傾斜面を有してもよい。前側傾斜面は、前方から後方に向かうにつれて徐々に上方に向かう傾斜面である。後側傾斜面は、後方から前方に向かうにつれて徐々に上方に向かう傾斜面である。 The retaining portion 27 of the insulator 20 has been described as being formed in a substantially rectangular parallelepiped shape by the front surface 27a and the rear surface 27b perpendicular to the front-rear direction and the upper surface 27c parallel to the front-rear direction, but the present invention is not limited thereto. .. The retaining portion 27 may have a front inclined surface continuously formed from the upper edge portion of the front surface 27a and a rear inclined surface continuously formed from the upper edge portion of the rear surface 27b. The front inclined surface is an inclined surface that gradually increases upward from the front to the rear. The rear inclined surface is an inclined surface that gradually rises upward from the rear to the front.
