近年、電気・電子機器の小型化が進むにつれ、コネクタの小型化の要求も強くなってきており、コネクタはより一層軽薄短小化が進んできている。軽薄短小化が進む中、アクチュエータやスライダー等の回動部材の稼動するスペースを確保するため、コンタクト上面（特にテール側）を露出することが公の事実となっている。しかしながら、コネクタの使用用途によってはコネクタの小型化（低背化）の要求がされることがなく、コンタクトが露出していると、防塵性が悪く、場合によっては接続不良の原因に繋がることも考えられる。
また、ＦＰＣをコネクタに挿入する際には挿入力の掛からない構造のものが要求され、ＦＰＣが完全に嵌合されているかどうかを目視で判別することも要求されている。
さらに、悪環境での使用も考えられ、客先要求により本出願人が提案した特許文献６より、さらに防塵性アップの要求が強くなってきている。
さらにまた、防塵性アップをした特許文献６や特許文献７の構造では、前記コンタクトを基板等に半田付けした際に、半田が前記回動部材の前記押圧部まで上がってしまい、前記押圧部が回動できなくなり、無理に回動しようとすると前記回動部材が破損してしまうといった問題が発生した。 In recent years, as electric and electronic devices have been miniaturized, there has been an increasing demand for miniaturization of connectors, and connectors are becoming lighter, thinner and smaller. As lightness and miniaturization progresses, it is a public fact that the upper surface of the contact (especially the tail side) is exposed in order to secure a space in which a rotating member such as an actuator or a slider operates. However, depending on the usage of the connector, there is no requirement for miniaturization (low profile) of the connector. If the contact is exposed, the dust-proof property is poor, and in some cases, it may cause connection failure. Conceivable.
Further, when the FPC is inserted into the connector, a structure having no insertion force is required, and it is also required to visually determine whether or not the FPC is completely fitted.
Furthermore, the use in bad environment is also considered, and the request | requirement of dust-proof improvement is still stronger than the patent document 6 which this applicant proposed by the customer request.
Furthermore, in the structures of Patent Document 6 and Patent Document 7 with improved dust resistance, when the contact is soldered to a substrate or the like, the solder goes up to the pressing portion of the rotating member, and the pressing portion is When the rotation is impossible and the rotation is forced, the rotation member is damaged.

本発明は、このような従来の問題点に鑑みてなされたもので、接続対象物の挿入力が掛からないで、防塵性が高く、基板への半田付けの際に半田が前記回動部材の押圧部まで上がらない構造のコネクタを提供せんとするものである。 The present invention has been made in view of such a conventional problem, and does not apply an insertion force of an object to be connected, has high dustproofness, and when soldering to a substrate, the solder is attached to the rotating member. It is intended to provide a connector having a structure that does not rise to the pressing portion.

最初に、図４（Ａ）の一方のコンタクト１４について説明する。一方の前記コンタクト１４は図４（Ａ）のように倒略Ｈ形状をし、少なくとも前記ＦＰＣ６４と接触する接触部２６（図４（Ａ）の図面の上側）と基板等に接続する接続部４０と前記ハウジング１２に固定する固定部３８と連結支点部３０と回動部材１８によって押圧される押受部３２と前記接続部４０の上部に半田上がり防止手段を備えている。前記接触部２６と前記押受部３２とは略クランク状の板状片の第一片２２の両端に設けられ、前記押受部３２の先端には内側に突出した突出部４２が設けられている。一端側に前記ハウジング１２に挿入される固定部３８を有する延設部３６と他端側に基板と接続する接続部４０とを有する第二片２４を備え、前記第一片２２と前記第二片２４はほぼ中間付近で連結支点部３０によって連結されている。前記接触部２６と前記連結支点部３０と前記接続部４０とは略クランク形状に配置されており、前記接続部４０には前記押受部３２側に突出するような突出台４４が設けられ、前記押受部３２と前記突出台４４との間で前記回動部材１８の押圧部５４が回動するようなっている。本実施例では前記コンタクト１４の連結支点部３０付近に、前記嵌合口２０と反対方向に傾斜する傾斜部２８が設けられている。該傾斜部２８を設けることで、低背化を図っている。また、前記突出台４４は前記回動部材１８の押圧部５４が回動する際に安定した回動をするために、押受部３２と接続部４０との間の間隔を調整するためのものであり、突出量はこのようなことを考慮して適宜設計する。前記半田上がり防止手段は、前記接続部４０の上部で、かつ、前記突出台４４に設けられている。前記半田上がり防止手段は、前記コネクタ１０を基板に半田付けした際に半田が前記回動部材１８の前記押圧部５４まで上がらないようにするものである。前記半田上がり防止手段としては、図９（Ａ）のようなスリット７４と、図９（Ｂ）のようなスリット溝７６と、図９（Ｃ）のようなスリット孔７８を挙げることができる。このように、スリット７４やスリット溝７６やスリット孔７８を設けることで、前記接続部４０から前記押圧部５４までの距離を長くし、半田が前記スリット７４や前記スリット溝７６や前記スリット孔７８に滞積して、前記押圧部５４まで到達しないようにしたものである。図１から図８の実施例では、図９（Ａ）の前記スリット７４を用いて半田上がりを防止している。前記コンタクト１４の突出台４４の端面４５から前記ハウジング１２の端面７５（図５の一点鎖線）までの距離と前記スリット７４の長さ（深さ）の比を３／５〜４／５にしている。前記コンタクト１４の突出台４４の端面４５から前記ハウジング１２の端面７５までの距離と前記スリット７４の長さ（深さ）の比とは、前記コンタクト１４の突出台４４の端面４５から前記ハウジング１２の端面７５までの距離に対して、前記スリット７４の長さ（深さ）を表したものである。３／５以下では半田上がりを防止することが出来なく、４／５以上では前記コンタクト１４の強度が弱くなり、破損する恐れがある。つまり、前記接続部４０の半田はいったん上昇すると前記スリット７４にぶつかり、進行方向がそれ、前記スリット７４にそって進むので、前記押圧５４までの距離が長くなり、到達しなくなる。つまり、比が３／５とは前記コンタクト１４の突出台４４の端面４５から前記ハウジング１２の端面７５までの距離が０．５ｍｍだった場合に、前記スリット７４の長さが０．３ｍｍということであり、比が４／５とは前記コンタクト１４の突出台４４の端面４５から前記ハウジング１２の端面７５までの距離が０．５ｍｍだった場合に、前記スリット７４の長さ（深さ）が０．４ｍｍということである。 First, one contact 14 in FIG. 4A will be described. One of the contacts 14 has a substantially H-shaped shape as shown in FIG. 4A, and at least a contact portion 26 that contacts the FPC 64 (upper side of the drawing of FIG. 4A) and a connection portion 40 that connects to a substrate or the like. Further, a fixing part 38 fixed to the housing 12, a connecting fulcrum part 30, a pressing part 32 pressed by the rotating member 18, and a solder rise prevention means are provided above the connection part 40. The contact portion 26 and the pressing portion 32 are provided at both ends of the first piece 22 of a substantially crank-shaped plate piece, and a protruding portion 42 protruding inward is provided at the tip of the pressing portion 32. Yes. A second piece 24 having an extending portion 36 having a fixing portion 38 inserted into the housing 12 on one end side and a connecting portion 40 connected to the substrate on the other end side is provided, and the first piece 22 and the second piece are provided. The pieces 24 are connected by a connecting fulcrum 30 near the middle. The contact portion 26, the connection fulcrum portion 30, and the connection portion 40 are arranged in a substantially crank shape, and the connection portion 40 is provided with a protruding base 44 that protrudes toward the pressing portion 32, The pressing portion 54 of the rotating member 18 is rotated between the pressing portion 32 and the protruding base 44. In this embodiment, an inclined portion 28 that is inclined in the direction opposite to the fitting port 20 is provided near the connection fulcrum portion 30 of the contact 14. By providing the inclined portion 28, the height is reduced. The protrusion 44 is for adjusting the interval between the pressing portion 32 and the connecting portion 40 in order to rotate stably when the pressing portion 54 of the rotating member 18 rotates. Therefore, the amount of protrusion is appropriately designed in consideration of the above. The solder rise prevention means is provided in the upper part of the connection portion 40 and on the protruding base 44. The solder rise prevention means prevents the solder from going up to the pressing portion 54 of the rotating member 18 when the connector 10 is soldered to the board. Examples of the solder rising prevention means include a slit 74 as shown in FIG. 9A, a slit groove 76 as shown in FIG. 9B, and a slit hole 78 as shown in FIG. 9C. Thus, by providing the slit 74, the slit groove 76, and the slit hole 78, the distance from the connecting portion 40 to the pressing portion 54 is increased, and the solder is the slit 74, the slit groove 76, and the slit hole 78. In this way, it does not reach the pressing portion 54. In the embodiment shown in FIGS. 1 to 8, the slit 74 shown in FIG. 9A is used to prevent the solder from rising. The ratio of the distance from the end surface 45 of the protruding base 44 of the contact 14 to the end surface 75 of the housing 12 (dashed line in FIG. 5) and the length (depth) of the slit 74 is 3/5 to 4/5. Yes. The ratio of the distance from the end surface 45 of the projecting base 44 of the contact 14 to the end surface 75 of the housing 12 and the length (depth) of the slit 74 is determined from the end surface 45 of the projecting base 44 of the contact 14 to the housing 12. This represents the length (depth) of the slit 74 with respect to the distance to the end surface 75 of the slit 74. If it is 3/5 or less, it is not possible to prevent the solder from rising, and if it is 4/5 or more, the strength of the contact 14 becomes weak and may be damaged. In other words, once the solder of the connecting portion 40 rises, it collides with the slit 74, and the traveling direction deviates and advances along the slit 74. Therefore, the distance to the press 54 becomes long and does not reach. That is, the ratio of 3/5 means that the length of the slit 74 is 0.3 mm when the distance from the end surface 45 of the protruding base 44 of the contact 14 to the end surface 75 of the housing 12 is 0.5 mm. The ratio of 4/5 means that when the distance from the end surface 45 of the protruding base 44 of the contact 14 to the end surface 75 of the housing 12 is 0.5 mm, the length (depth) of the slit 74 is 0.4mm.

前記接続部４０の配置位置としては、基板のランド位置や基板のパターン位置や狭スペース等を考慮して適宜設計する。即ち、前記接続部４０は要求仕様に応じて、前記接触部２６に対向する側や前記押受部３２に対向する側に設けられることになり、また、ランドの位置によっては千鳥に設けることもある。一方の前記コンタクト１４では、前記接続部４０を前記押受部３２に対向する側に設けている。前記接触部２６は、ＦＰＣ６４と接触し易いように凸部形状にしており、前記接続部４０は本実施例では図４（Ａ）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ＦＰＣ６４の仕様によっては、前記接触部２６と対向する側にも接触部２６を設ける場合もある。即ち、２つの接触部２６、２６を設けて、前記ＦＰＣ６４を挟持するようにしてもよい。本実施例では、一方の前記コンタクト１４では、前記連結支点部３０から前記接触部２６に対向するように延設部３６を設け、該延設部３６上に前記ハウジング１２に固定するための固定部３８を設けている。前記固定部３８の大きさや形状は、保持力や前記ハウジング１２の強度等を考慮して適宜設計する。 The arrangement position of the connecting portion 40 is appropriately designed in consideration of the land position of the substrate, the pattern position of the substrate, the narrow space, and the like. That is, the connecting part 40 is provided on the side facing the contact part 26 or the side facing the pressing part 32 according to the required specifications, and depending on the position of the land, it may be provided in a staggered manner. is there. In the one contact 14, the connecting portion 40 is provided on the side facing the pressing portion 32. The contact portion 26 has a convex shape so that it can easily come into contact with the FPC 64. In the present embodiment, the connection portion 40 is a surface mount type (SMT) as shown in FIG. But it ’s okay. Depending on the specifications of the FPC 64, the contact portion 26 may be provided on the side facing the contact portion 26. That is, two contact portions 26 and 26 may be provided to sandwich the FPC 64. In the present embodiment, one of the contacts 14 is provided with an extending portion 36 so as to face the contact portion 26 from the connection fulcrum portion 30, and fixing for fixing the housing 12 on the extending portion 36. A portion 38 is provided. The size and shape of the fixing portion 38 are appropriately designed in consideration of the holding force, the strength of the housing 12, and the like.

前記連結支点部３０と前記押受部３２とは、前記ＦＰＣ６４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ＦＰＣ６４が前記ハウジング１２の嵌合口２０内に挿入された後に、前記回動部材１８の押圧部５４が前記コンタクト１４の接続部４０の突出台４４と押受部３２との間で回動すると、前記押受部３２が押圧部５４によって押し上げられることで前記コンタクト１４の連結支点部３０の下端（図４（Ａ）の下側）を支点にし、前記コンタクト１４の連結支点部３０の上端が前記接触部２６側に傾くことによって、前記接触部２６が前記ＦＰＣ６４側に押圧される。前記連結支点部３０と前記押受部３２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。また、前記コンタクト１４の押受部３２の先端に突出部４２を設け、前記回動部材１８の押圧部５４を前記コンタクト１４の押受部３２と接続部４０の突出台４４との間で回動させるとき、前記回動部材１８の係止孔５８に係合させることで、前記回動部材１８の回動に対する強い反発力に対抗することが望ましい。前記突出部４２の大きさは、このような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１８の係止孔が引っ掛かる程度に適宜設計する。 The connecting fulcrum part 30 and the pressing part 32 are parts for performing the following actions when the FPC 64 is inserted. After the FPC 64 is inserted into the fitting port 20 of the housing 12, the pressing portion 54 of the rotating member 18 rotates between the protruding base 44 of the connecting portion 40 of the contact 14 and the pressing portion 32. When the pressing portion 32 is pushed up by the pressing portion 54, the lower end of the connection fulcrum 30 of the contact 14 (the lower side in FIG. 4A) is used as a fulcrum, and the upper end of the connection fulcrum 30 of the contact 14 is By tilting toward the contact portion 26 side, the contact portion 26 is pressed toward the FPC 64 side. The sizes and shapes of the connecting fulcrum part 30 and the pressing part 32 are appropriately designed in order to achieve such an action. Further, a protrusion 42 is provided at the tip of the pressing portion 32 of the contact 14, and the pressing portion 54 of the rotating member 18 is rotated between the pressing portion 32 of the contact 14 and the protruding base 44 of the connecting portion 40. When it is moved, it is desirable to resist the strong repulsive force against the rotation of the rotating member 18 by engaging with the locking hole 58 of the rotating member 18. The size of the protruding portion 42 may be any size as long as it can fulfill such a role, and is appropriately designed to the extent that the locking hole of the rotating member 18 is caught.

次に、もう一方のコンタクト１６について説明する。ここでは、上述した一方のコンタクト１４との相違部分についてのみ説明する。もう一方の前記コンタクト１６も図４（Ｂ）のように一方の前記コンタクト１４と同様に倒略Ｈ字形状をしており、主にＦＰＣ６４と接触する接触部２６（図４（Ｂ）の図面の上側）と基板に接続する接続部４０とハウジング１２に固定する固定部３８と連結支点部３０と前記回動部材１８のよって押圧される押受部３２とを備えている。これらの前記接触部２６と前記連結支点部３０と前記接続部４０は、略倒Ｕ字形状に配置されている。前記接続部４０は、一方の前記コンタクト１４と同様に表面実装タイプ（ＳＭＴ）にしているが、ディップタイプでも良い。 Next, the other contact 16 will be described. Here, only a difference from the above-described one contact 14 will be described. The other contact 16 has a substantially H-shaped shape as in the case of the one contact 14 as shown in FIG. 4B, and is mainly a contact portion 26 that comes into contact with the FPC 64 (FIG. 4B). A connecting portion 40 connected to the substrate, a fixing portion 38 fixed to the housing 12, a connecting fulcrum portion 30, and a pressing portion 32 pressed by the rotating member 18. The contact part 26, the connecting fulcrum part 30, and the connection part 40 are arranged in a substantially inverted U shape. The connection portion 40 is a surface mount type (SMT) like the one of the contacts 14, but may be a dip type.

一方の前記コンタクト１４ともう一方の前記コンタクト１６の相違点は、幾分形状的な違いはあるものの前記接続部４０と前記延設部３６とが逆にしただけである。即ち、一方の前記コンタクト１４では、前記接続部４０を前記押受部３２と対向する側に、前記延設部３６を前記接触部２６と対向する側に設けているのに対し、もう一方の前記コンタクト１６では、前記接続部４０を前記接触部２６と対向する側に、前記延設部３６を前記押受部３２と対向する側に設けている。もう一方の前記コンタクト１６の延設部３６に前記ハウジング１２に固定するための固定部３８を設けている。 The difference between the one contact 14 and the other contact 16 is that the connecting portion 40 and the extending portion 36 are reversed, although there are some differences in shape. That is, in one contact 14, the connecting portion 40 is provided on the side facing the pressing portion 32, and the extending portion 36 is provided on the side facing the contact portion 26, whereas the other contact 14 is provided. In the contact 16, the connecting portion 40 is provided on the side facing the contact portion 26, and the extending portion 36 is provided on the side facing the pressing portion 32. A fixing portion 38 for fixing to the housing 12 is provided in the extending portion 36 of the other contact 16.

ここで、前記回動部材１８の押圧部５４の移動及び回動の仕方について図８に基づいて説明する。
第一に、図８（Ａ）のように前記接続対象物と前記コネクタ１０との接続前の状態で、前記押圧部５４の下端７０側が前記押受部３２の突出部４２と接続部４０の突出台４４との間に位置する。
第二に、図８（Ｂ）のように前記操作部５６を回動（図面の時計回り方向）させると前記押圧部５４が嵌合口２０と反対方向に移動し、前記押圧部５４の下端７０側が前記押受部３２の突出部４２と接続部４０の突出台４４との間に挟持される。
第三に、図８（Ｃ）のように前記操作部５６をさらに回動させると第二の位置で前記押圧部５４が押圧部５４の中心を回転軸７２として回動する。
第四に、図８（Ｄ）のように前記操作部５６をさらに回動させると第三の位置で前記押圧部５４が押圧部５４の中心を回転軸７２として回動し、前記押圧部５４が前記押受部３２と前記接続部４０の突出台４４との間でほぼ垂直になり回転軸７２が前記突出部４２に接した上端６８側に移動する。
第五に、図８（Ｅ）のように前記操作部５６をさらに回動させると第四の位置で前記押圧部５４が前記突出部４２に接した上端６８側を中心に回動し、前記押圧部５４を前記突出部４２に引っ掛かった状態に係合させる。
即ち、前記押圧部５４は最初は移動し、その後回動し、さらに回動を続けると回転軸７２が変化して、省スペース間でコンパクトな回動（回転）を行なうものである。
つまり、本発明のコネクタ１０では、前記ＦＰＣ６４等の接続対象物を嵌合口２０内に挿入する際に挿入力の掛からない（所謂、ゼロ・インサーション・フォース（ＺＩＦ））構造で、前記回動部材１８の押圧部５４をより前記コンタクト１４、１６の突出部４２側で回動させる（より突出部４２側で前記コンタクト１４、１６の押受部３２を押し上げる）ことで小さな力で前記回動部材１８をロックできる構造で、かつ、前記回動部材１８の押圧部５４でより前記コンタクト１４，１６の突出部４２側の押受部３２を押し上げることで高い接触力を得られる構造になっている。 Here, how to move and rotate the pressing portion 54 of the rotating member 18 will be described with reference to FIG.
First, as shown in FIG. 8A, in the state before the connection object and the connector 10 are connected, the lower end 70 side of the pressing portion 54 is connected to the protruding portion 42 of the pressing portion 32 and the connecting portion 40. It is located between the protrusions 44.
Second, as shown in FIG. 8B, when the operation portion 56 is rotated (clockwise in the drawing), the pressing portion 54 moves in the opposite direction to the fitting port 20, and the lower end 70 of the pressing portion 54. The side is sandwiched between the protruding portion 42 of the pressing portion 32 and the protruding base 44 of the connecting portion 40.
Third, as shown in FIG. 8C, when the operation portion 56 is further rotated, the pressing portion 54 rotates about the center of the pressing portion 54 as the rotation shaft 72 at the second position.
Fourth, when the operation portion 56 is further rotated as shown in FIG. 8D, the pressing portion 54 is rotated about the center of the pressing portion 54 as the rotation shaft 72 at the third position, and the pressing portion 54 is rotated. Becomes substantially vertical between the pressing portion 32 and the protruding base 44 of the connecting portion 40, and the rotating shaft 72 moves to the upper end 68 side in contact with the protruding portion 42.
Fifth, when the operation portion 56 is further rotated as shown in FIG. 8E, the pressing portion 54 is rotated around the upper end 68 side in contact with the protruding portion 42 at the fourth position, The pressing portion 54 is engaged in a state of being caught by the protruding portion 42.
That is, the pressing portion 54 moves first, then rotates, and further rotates, the rotating shaft 72 changes to perform a compact rotation (rotation) between spaces.
In other words, in the connector 10 of the present invention, when the object to be connected such as the FPC 64 is inserted into the fitting port 20, an insertion force is not applied (so-called zero insertion force (ZIF)) structure, and the rotation is performed. By rotating the pressing portion 54 of the member 18 closer to the protruding portion 42 side of the contacts 14 and 16 (pushing up the pressing portion 32 of the contacts 14 and 16 on the protruding portion 42 side), the rotation is performed with a small force. The member 18 can be locked, and the pressing portion 54 of the rotating member 18 can push the pressing portion 32 on the protruding portion 42 side of the contacts 14 and 16 to obtain a high contact force. Yes.

次に、回動部材１８について説明する。この回動部材１８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）やこれらの合成材料を挙げることができる。
前記回動部材１８は主に前記ハウジング１２に回動可能に装着される軸部分と前記コンタクト１４、１６の押受部３２を押圧する押圧部５４と前記コンタクト１４、１６の突出部４２が係合する係止孔５８と操作部５６とを備えている。本実施例では、前記回動部材１８を断面略Ｕ字形状にしている。前記軸は、回動部材１８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１８が回動可能に適宜装着され、上述したように前記押圧部５４が回動する際に回転軸７２が変化するように前記軸と前記ハウジング１２の軸受け部との関係ではクリアランスを設けている。また、長手方向両側には、前記コンタクト１４、１６の押受部３２を押圧した際に回動部材１８が高さ（図面の上）方向に持ち上がらないようにするためにハウジング１２と係合するロック部が設けられている。ロック部の形状や大きさ等は、ハウジング１２に係合できれば如何なるものでもよく、上述の役割やコネクタ１０の大きさや強度等を考慮して適宜設計する。 Next, the rotating member 18 will be described. The rotating member 18 is an electrically insulating plastic and is manufactured by a known technique of injection molding. This material is appropriately selected in consideration of dimensional stability, workability, cost, etc. Examples include butylene terephthalate (PBT), polyamide (66PA, 46PA), liquid crystal polymer (LCP), polycarbonate (PC), and synthetic materials thereof.
The rotating member 18 mainly includes a shaft portion rotatably mounted on the housing 12, a pressing portion 54 that presses the pressing portion 32 of the contacts 14, 16, and a protruding portion 42 of the contacts 14, 16. An engaging hole 58 and an operation portion 56 are provided. In this embodiment, the rotating member 18 has a substantially U-shaped cross section. The shaft is a fulcrum for rotating the rotating member 18, and the rotating member 18 is appropriately mounted on both sides in the longitudinal direction of the housing 12 so that the pressing portion 54 rotates as described above. At this time, a clearance is provided in the relationship between the shaft and the bearing portion of the housing 12 so that the rotating shaft 72 changes. Further, on both sides in the longitudinal direction, the rotating member 18 is engaged with the housing 12 so that the rotating member 18 does not lift in the height (upward in the drawing) direction when the pressing portion 32 of the contact 14, 16 is pressed. A lock portion is provided. The lock portion may have any shape, size, etc. as long as it can engage with the housing 12 and is appropriately designed in consideration of the above-described role, the size, strength, etc. of the connector 10.

前記回動部材１８の前記押圧部５４は、コンタクト１４、１６の押受部３２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ことが望ましく、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、図５（Ａ）及び図６（Ａ）のように回動部材１８を矢印「イ」方向及び矢印「ハ」方向に回動させ、コンタクト１４、１６の押受部３２と接続部４０の突出台４４との間で回転させることで、押圧部５４の大きさの変化によりコンタクト１４、１６の押受部３２が持ち上げられ、ＦＰＣ６４をコンタクト１４、１６の接触部２６側に押し付けている。押圧部５４の形状としては、コンタクト１４、１６の押受部３２と接続部４０の突出台４４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コンタクト１４、１６の押受部３２を押し上げられれば、如何なるものでもよい。前記押圧部５４の形状や大きさは、このようなことを考慮して適宜設計する。また、前記回動部材１８には、操作性を考慮して、操作部５６が設けられている。特徴的なのは、一方の前記コンタクト１４の押受部３２と突出台４４との間で回動することで、一方及びもう一方の前記コンタクト１４、１６の押受部３２を押し上げて、一方及びもう一方の前記コンタクト１４、１６の接触部２６をＦＰＣ６４に接触させている。 The pressing portion 54 of the rotating member 18 is a portion that is pressed against the pressing portion 32 of the contacts 14, 16. The shape of the pressing portion 54 is preferably an elongated shape, and in this embodiment, an elliptical shape. By making the shape oval in this way, as shown in FIGS. 5A and 6A, the rotating member 18 is rotated in the directions of the arrows “I” and “C”, and the contacts 14 and 16 are rotated. By rotating between the pressing portion 32 and the protruding base 44 of the connecting portion 40, the pressing portion 32 of the contacts 14 and 16 is lifted due to the change in the size of the pressing portion 54, and the FPC 64 is connected to the contacts 14 and 16. It is pressed against the contact portion 26 side. As the shape of the pressing portion 54, it can be rotated between the pressing portion 32 of the contacts 14, 16 and the protruding base 44 of the connecting portion 40, and the pressing of the contacts 14, 16 is caused by the difference in size such as the major axis and the minor axis. Any unit can be used as long as the unit 32 can be pushed up. The shape and size of the pressing portion 54 are appropriately designed in consideration of the above. The rotating member 18 is provided with an operation portion 56 in consideration of operability. Characteristically, by rotating between the pressing portion 32 of one of the contacts 14 and the protruding base 44, the pressing portion 32 of one and the other of the contacts 14 and 16 is pushed up, and one and the other. The contact portion 26 of one of the contacts 14 and 16 is in contact with the FPC 64.

前記回動部材１８を回動した際に、前記回動部材１８の回動に対する反発力が強い為に、前記コンタクト１４、１６の突出部４２が係合する係止孔５８が別個独立に設けられている。前記係止孔５８を別個独立に設けることで、前記回動部材１８の強度アップや回動時の変形を防止している。
上述した前記回動部材１８は前記ハウジング１２の嵌合口２０と反対側（一方のコンタクト１４の接続部側）に回動自在に装着されている。
