The FPC 80 mainly includes a contact 84 (a lower contact is not shown) that contacts the first contact portion 22 and the second contact portion 40 of the contact 14, a pattern connected to the circuit from the contact 84, and the housing 12. A locking portion 82 that engages with the convex portion 56 is provided. As shown in FIG. 1, in this embodiment, the contacts 84 of the FPC 80 are arranged in a single row. The engaging portion 82 may have any shape as long as it can be engaged with the convex portion 56 of the housing 12, but in this embodiment, it may be a U-shaped notch as shown in FIG. It may be a through hole. Depending on the specification, the through hole may be a stop hole.

図に基づいて本発明のコネクタ１０の構成部品について説明する。まず、コンタクト１４について説明する。前記コンタクト１４は金属製であり、公知技術のプレス加工によって製作されている。前記コンタクト１４の材質としては、バネ性や導電性などが要求されるので、黄銅やベリリウム銅やリン青銅等を挙げることができる。本実施例では、前記コンタクト１４は前記ハウジング１２の挿入孔５２内に挿入される。 The components of the connector 10 of the present invention will be described based on the drawings. First, the contact 14 will be described. The contact 14 is made of metal and is manufactured by a known press working. The material of the contact 14 is required to be springy or conductive, and can include brass, beryllium copper, phosphor bronze, and the like. In this embodiment, the contact 14 is inserted into the insertion hole 52 of the housing 12.

前記コンタクト１４は、少なくとも一方端に第一接触部２２と他方端に押受部２４とを有する第一片２０と、他方端に接続部３０を有する第二片２８と、前記第一接触部２２と前記接続部３０の間に位置するとともに前記第一片２０と前記第二片２８の一方端を連結する弾性部３６及び支点部３８とを有している。つまり、前記コンタクト１４は、図示はしないが略逆倒ｈ形状をし、前記第一片２０の第一接触部２２と前記弾性部３６と前記支点部３８と前記接続部３０は略クランク形状に配置されている。本実施例では、図３のように、前記支点部３８から前記第一接触部２２と同一方向側に延設した延設部３２が設けられるとともにその先端に第二接触部４０を有した略逆倒Ｈ字形状をしており、上下２点接点になっており、前記第一片２０の第一接触部２２と前記弾性部３６と前記支点部３８と前記接続部３０は略クランク形状に配置されている。 The contact 14 includes a first piece 20 having at least one first contact portion 22 at one end and a pressing portion 24 at the other end, a second piece 28 having a connection portion 30 at the other end, and the first contact portion. And an elastic part 36 and a fulcrum part 38 that are located between the connecting part 30 and the one end of the first piece 20 and the second piece 28. That is, although not shown, the contact 14 has a substantially inverted h shape, and the first contact portion 22, the elastic portion 36, the fulcrum portion 38, and the connection portion 30 of the first piece 20 have a substantially crank shape. Has been placed. In this embodiment, as shown in FIG. 3, an extended portion 32 extending from the fulcrum portion 38 in the same direction as the first contact portion 22 is provided, and a second contact portion 40 is provided at the tip thereof. It has a reverse H-shape and has two upper and lower contact points, and the first contact portion 22, the elastic portion 36, the fulcrum portion 38, and the connection portion 30 of the first piece 20 have a substantially crank shape. Has been placed.

前記固定部２０は、前記コンタクト１４の接続部３０近傍に設けている。前記固定部２０の位置や大きさは、前記コンタクト１４の保持力や接続安定性等を考慮して適宜設計している。 The fixing portion 20 is provided in the vicinity of the connection portion 30 of the contact 14. The position and size of the fixing portion 20 are appropriately designed in consideration of the holding force of the contact 14, connection stability, and the like.

２つの接触部である前記第一接触部２２と第二接触部４０は、前記ＦＰＣ８０と接触し易いように凸部形状にしており、前記接続部３０は本実施例では図１（Ｂ）のように表面実装タイプ（ＳＭＴ）にしているが、ディップタイプでも良い。前記第二接触部４０の先端を前記第一接触部２２側に屈曲させている。このように、屈曲させることで、前記第二接触部４０の先端で、前記ＦＰＣ８０が挿入された際に前記ＦＰＣ８０が下側（第二接触部４０側）に湾曲しないで、前記ＦＰＣ８０が挿入し易いようにしている。屈曲の角度は、下述する凸部５６と前記第二接触部４０の先端が同一高さになるようにしている。また、屈曲させることで、ＦＰＣを抜く際には前記延設部３２に弾性があるため、前記回動部材１６を開いた状態にすると前記第二接触部４０で前記ＦＰＣ８０押し上げるように作用するので前記ＦＰＣ８０を外し易くなる。 The first contact portion 22 and the second contact portion 40 which are two contact portions are formed in a convex shape so as to easily come into contact with the FPC 80, and the connection portion 30 in FIG. As described above, the surface mount type (SMT) is used, but a dip type may be used. The tip of the second contact portion 40 is bent toward the first contact portion 22 side. Thus, by bending, the FPC 80 is inserted at the tip of the second contact portion 40 without bending the FPC 80 downward (second contact portion 40 side) when the FPC 80 is inserted. It is made easy. The angle of bending is such that the convex portion 56 described below and the tip of the second contact portion 40 have the same height. In addition, since the extending portion 32 is elastic when bent to pull out the FPC, the second contact portion 40 acts to push up the FPC 80 when the rotating member 16 is opened. It becomes easy to remove the FPC 80.

前記支点部３８と前記弾性部３６と前記押受部２４とは、前記ＦＰＣ８０が挿入された際に、次のような作用を果たすための部分である。前記ＦＰＣ８０が前記ハウジング１２の嵌合口１８内に挿入された後に、前記回動部材１６の押圧部４６が前記コンタクト１４の接続部３０と押受部２４との間で回動すると、前記押受部２４が前記押圧部４６によって押し上げられることで前記コンタクト１４の支点部３８を支点にし、前記コンタクト１４の弾性部３６が前記第一接触部２２側に傾くことによって、前記第一接触部２２が前記ＦＰＣ８０に押圧される。前記支点部３８と前記弾性部３６と前記押受部２４の大きさや形状は、このような作用を果たすために、適宜設計されている。 The fulcrum part 38, the elastic part 36, and the pressing part 24 are parts for performing the following actions when the FPC 80 is inserted. After the FPC 80 is inserted into the fitting port 18 of the housing 12, when the pressing portion 46 of the rotating member 16 rotates between the connection portion 30 of the contact 14 and the pressing portion 24, the pressing When the portion 24 is pushed up by the pressing portion 46, the fulcrum portion 38 of the contact 14 is used as a fulcrum, and the elastic portion 36 of the contact 14 is inclined toward the first contact portion 22, whereby the first contact portion 22 is The FPC 80 is pressed. The size and shape of the fulcrum portion 38, the elastic portion 36, and the pressing portion 24 are appropriately designed to achieve such an action.

さらに、前記コンタクト１４の押受部２４の先端に膨れ防止手段を設けることが好ましい。前記回動部材１６の押圧部４６を前記コンタクト１４の押受部２４と接続部３０との間で回動させるとき、前記回動部材１６の回動に対する反発力が強い為に、前記回動部材１６の中央部が膨れる傾向があるが、前記膨れ防止手段を設けることにより、かかる傾向を防ぐようにすることができるためである。さらに、前記膨れ防止手段として、前記押受部２４の先端に突出部２６を設けることがより好適である。前記突出部２６の大きさは、上記役割を果たすことが出来れば如何なる大きさでもよく、前記回動部材１６の押圧部４６が引っ掛かる程度に適宜設計する。 Furthermore, it is preferable to provide a swelling preventing means at the tip of the pressing portion 24 of the contact 14. When the pressing portion 46 of the rotating member 16 is rotated between the pressing portion 24 and the connecting portion 30 of the contact 14, since the repulsive force against the rotation of the rotating member 16 is strong, the rotation This is because the central portion of the member 16 tends to swell, but the tendency can be prevented by providing the swelling preventing means. Further, it is more preferable to provide a protruding portion 26 at the tip of the pressing portion 24 as the swelling preventing means. The size of the protruding portion 26 may be any size as long as it can fulfill the above role, and is appropriately designed to the extent that the pressing portion 46 of the rotating member 16 is caught.

次に、回動部材１６について説明する。この回動部材１６は電気絶縁性のプラスチックであり、公知技術の射出成形によって製作され、この材質としては寸法安定性や加工性やコスト等を考慮して適宜選択するが、一般的にはポリブチレンテレフタレート（ＰＢＴ）やポリアミド（６６ＰＡ、４６ＰＡ）や液晶ポリマー（ＬＣＰ）やポリカーボネート（ＰＣ）やポリフェニレンサルファイド（ＰＰＳ）やこれらの合成材料を挙げることができる。前記回動部材１６は主に操作部４２とハウジング１２に回動可能に装着される軸部分と前記コンタクト１４の押受部２４が入る係止孔４４と押受部２４を押圧する押圧部４６とを備えている。前記軸は、回動部材１６を回動するための支点であり、ハウジング１２の長手方向両側に回動部材１６が回動可能に適宜装着されている。 Next, the rotating member 16 will be described.

前記押圧部４６は、前記コンタクト１４の押受部２４に押し付ける部分であり、その形状としては細長形状にする。前記押圧部４６の形状は、本実施例では楕円形状をしている。このように楕円形状にすることによって、前記回動部材１６を回動させ、前記コンタクト１４の押受部２４と接続部３０との間で回転させることで、前記押圧部４６の大きさの変化により前記コンタクト１４の押受部２４が持ち上げられ、前記ＦＰＣ８０に前記コンタクト１４の第一接触部２２側を押し付けている。前記押圧部４６の形状としては、前記コンタクト１４の押受部２４と接続部３０との間で回転でき、長軸と短軸といった大きさの違いにより前記コンタクト１４の押受部２４を押し上げられれば、如何なるものでもよい。 The pressing portion 46 is a portion that is pressed against the pressing portion 24 of the contact 14 and has an elongated shape. The pressing portion 46 has an elliptical shape in this embodiment. By changing the size of the pressing portion 46 by rotating the rotating member 16 and rotating between the receiving portion 24 and the connecting portion 30 of the contact 14 by making the elliptical shape in this way. As a result, the holding portion 24 of the contact 14 is lifted, and the first contact portion 22 side of the contact 14 is pressed against the FPC 80. As the shape of the pressing portion 46, the pressing portion 24 of the contact 14 can be rotated between the pressing portion 24 and the connecting portion 30, and the pressing portion 24 of the contact 14 can be pushed up due to a difference in size such as a major axis and a minor axis. Anything may be used.

また、前記回動部材１６を回動した際に、前記回動部材１６の回動に対する反発力が強く、前記回動部材１６の中央部が膨れてしまうことを防ぐようにする為に、前記コンタクト１４の押受部２４が入る係止孔４４が別個独立に設けられている。別個独立に設けることで、結果的に隣接する前記コンタクト１４の間には、仕切り壁４８が設けられることになり、前記係止孔４４を別個独立に設け、かつ、前記仕切り壁４８を設けることで、前記回動部材１６の強度アップや回動時の変形を防止している。 Further, when the rotating member 16 is rotated, the repulsive force against the rotation of the rotating member 16 is strong, and in order to prevent the central portion of the rotating member 16 from expanding, A locking hole 44 for receiving the pressing portion 24 of the contact 14 is provided separately and independently. By providing them separately, as a result, a partition wall 48 is provided between the adjacent contacts 14, the locking holes 44 are provided separately and the partition wall 48 is provided. Thus, the strength of the rotating member 16 is prevented from being increased and deformation during rotation is prevented.

さらに、前記操作部４２は、前記回動部材１６を回動させる際に、指や治具等で押す部分である。前記操作部４２の形状・大きさは、指や治具等で押せればよく、コネクタの小型化や強度や加工性や操作性等を考慮して適宜設計する。 Furthermore, the operation unit 42 is a portion that is pushed by a finger, a jig, or the like when the rotating member 16 is rotated. The shape and size of the operation unit 42 may be pressed with a finger or a jig, and is designed as appropriate in consideration of downsizing, strength, workability, operability, and the like of the connector.

The convex portion 56 is a portion that engages with the locking portion 82 of the FPC 80, and the shape and size of the convex portion 56 follows the locking portion 82 and has a holding force, strength, workability, downsizing, etc. To design appropriately. As the shape of the convex portion 56, in addition to the quadrangular prism as in the present embodiment, a cylinder, a triangular prism, a spherical diameter, and the like can be considered.

最後に、固定タブ５８について説明する。前記固定タブ５８は金属製であり、公知技術のプレス加工によって製作されている。前記固定タブ５８の材質としては、加工性やバネ性や導電性などが要求されるので、黄銅やベリリウム銅やリン青銅等を挙げることができる。本実施例では、前記固定タブ５８は前記ハウジング１２の嵌合口１８側で、長手方向の両側に装着されている。 Finally, the fixing tab 58 will be described. The fixing tab 58 is made of metal and is manufactured by a known press working. As the material of the fixing tab 58, workability, springiness, conductivity, and the like are required, and examples thereof include brass, beryllium copper, and phosphor bronze. In the present embodiment, the fixing tabs 58 are mounted on both sides in the longitudinal direction on the fitting port 18 side of the housing 12.

ここで、前記ＦＰＣ８０の保持方法について説明する。
第一に、前記ＦＰＣ８０を前記嵌合口１８内に挿入する。
第二に、前記回動部材１６を回動させると、次のような作用が生じ、前記ＦＰＣ８０の係止部８２が前記ハウジング１２の凸部５６に係合し、保持される。
前記回動部材１６の押圧部４６が前記コンタクト１４の押受部２４に作用すると、前記ハウジング１２に保持された前記コンタクト１４の接続部３０は変位せず、前記コンタクト１４の押受部２４のみが前記押圧部４６によって押し上げられ、前記支点部３８を支点にし、前記弾性部３６が前記第一接触部２２側に傾くことによって、前記ＦＰＣ８０を直に押圧することなく、前記第一接触部２２が前記ＦＰＣ８０側に変位（この際に下側接触部である前記第二接触部４０は前記第一接触部２２に連動し、下側に変位）し、押圧することにより前記ＦＰＣ８０が下方変位して、前記ＦＰＣ８０の係止部８２が前記ハウジング１２の凸部５６に係合する。つまり、前記ＦＰＣ８０挿入時には、挿入力が掛からない状態で挿入でき、前記回動部材１６を回転することで、前記回動部材１６が前記コンタクト１４を弾性変形させて、前記コンタクト１４の上側の第一接触部２２が前記ＦＰＣ８０の接点に接触すると同時に前記ＦＰＣ８０を押し下げることで、前記ＦＰＣ８０の係止部８２が前記ハウジング１２の凸部５６と係合し、係合することで前記ＦＰＣ８０を保持できる。 Here, a method of holding the FPC 80 will be described.
First, the FPC 80 is inserted into the fitting port 18.
Secondly, when the rotating member 16 is rotated, the following action occurs, and the locking portion 82 of the FPC 80 is engaged with and held by the convex portion 56 of the housing 12.
When the pressing portion 46 of the rotating member 16 acts on the pressing portion 24 of the contact 14, the connection portion 30 of the contact 14 held by the housing 12 is not displaced, only the pressing portion 24 of the contact 14. Is pushed up by the pressing part 46, the fulcrum part 38 is used as a fulcrum, and the elastic part 36 tilts toward the first contact part 22 side, so that the first contact part 22 is not pressed directly. Is displaced to the FPC 80 side (in this case, the second contact portion 40 which is the lower contact portion is interlocked with the first contact portion 22 and displaced downward), and the FPC 80 is displaced downward by pressing. Thus, the locking portion 82 of the FPC 80 engages with the convex portion 56 of the housing 12. That is, when the FPC 80 is inserted, the FPC 80 can be inserted without applying an insertion force. By rotating the rotating member 16, the rotating member 16 elastically deforms the contact 14, and the upper side of the contact 14 is changed. By pressing down the FPC 80 at the same time when the one contact portion 22 contacts the contact point of the FPC 80, the locking portion 82 of the FPC 80 is engaged with the convex portion 56 of the housing 12, and the FPC 80 can be held by being engaged. .

本発明の活用例としては、携帯電話やノートパソコンやデジタルカメラ等の電気機器や電子機器に使用されるコネクタ１０に活用され、特に、別部材を使用することがなく、安定したフレキシブルプリント基板（以下「ＦＰＣ」という）の接続を得られる構造に関するものである。 As an application example of the present invention, it is used for a connector 10 used in an electric device or an electronic device such as a mobile phone, a notebook computer, or a digital camera, and in particular, a separate flexible printed circuit board (without using a separate member) (Hereinafter referred to as “FPC”).
