Description

アンテナ基板接続ユニットAntenna board connection unit
　本発明は、アンテナ基板およびアンテナ基板に接続される接続用基板を相互に接続するアンテナ基板接続ユニットに関する。 The present invention relates to an antenna substrate connection unit for mutually connecting an antenna substrate and a connection substrate connected to the antenna substrate.
　携帯電話等の携帯端末機器においては、通信システムの一部を構成するアンテナユニットが内蔵されている。アンテナユニットは、例えば、特許文献１における図３にも示されるように、アンテナが実装されたアンテナ回路基板と、アンテナ切替スイッチおよび無線回路を含んで構成される通信制御回路基板と、各基板に設けられる同軸コネクタと、二つの同軸コネクタを接続する同軸ケーブルとを含んで構成されるものが提案されている。また、２つ折れ携帯電話において、例えば、特許文献２にも示されるように、アンテナユニットが、アンテナが設けられた一枚の基板の表面部と、アンテナ制御回路が形成されるその基板の裏面部と、表面部および裏面部にそれぞれ、設けられる同軸コネクタと、二つの同軸コネクタを接続する同軸ケーブルとを含んで構成されるものも提案されている。このような携帯電話等の携帯端末機器においては、小型軽量化および低背化が要望されるのでアンテナユニットの小型化および薄型化も要望されている。また、アンテナ周波数特性の観点から同軸ケーブルの長さも極力短くすることも要望される。 Mobile terminal devices such as mobile phones have built-in antenna units that form part of the communication system. For example, as shown in FIG. 3 in Patent Document 1, the antenna unit includes an antenna circuit board on which an antenna is mounted, a communication control circuit board including an antenna changeover switch and a radio circuit, and each board. There has been proposed a configuration including a coaxial connector provided and a coaxial cable connecting the two coaxial connectors. In a two-fold mobile phone, for example, as shown in Patent Document 2, the antenna unit includes a front surface portion of one substrate on which an antenna is provided, and a rear surface of the substrate on which an antenna control circuit is formed. There has also been proposed a configuration including a coaxial connector provided on each of the first portion, the front surface portion, and the rear surface portion, and a coaxial cable connecting the two coaxial connectors. In such mobile terminal devices such as mobile phones, there is a demand for a reduction in size and weight and a reduction in height. In addition, from the viewpoint of antenna frequency characteristics, it is desired to shorten the length of the coaxial cable as much as possible.
　アンテナ基板接続ユニットの一部を構成する同軸コネクタは、例えば、特許文献３にも示されるように、雄コネクタおよび雌コネクタを含んで構成されている。例えば、同軸ケーブルの一端が基板に接続される場合、図７に示されるように、雌コネクタが基板に固定される。同軸ケーブルの一端の中心導体を雌コネクタに結線する場合、先ず、雌コネクタの中心曲がり板状導体の端部が、半田付け作業により、同軸ケーブルの中心導体に固定される。次に、雌コネクタの導体圧着部および外皮圧着部が、それぞれ、同軸ケーブルに対しかしめられることにより、その結線が完了することとなる。 The coaxial connector that constitutes a part of the antenna substrate connection unit includes, for example, a male connector and a female connector as disclosed in Patent Document 3. For example, when one end of the coaxial cable is connected to the board, the female connector is fixed to the board as shown in FIG. When the central conductor at one end of the coaxial cable is connected to the female connector, first, the end of the central bent plate-like conductor of the female connector is fixed to the central conductor of the coaxial cable by a soldering operation. Next, the conductor crimping portion and the outer skin crimping portion of the female connector are respectively crimped to the coaxial cable, thereby completing the connection.

　上述のアンテナ基板接続ユニットの結線において、例えば、直径が約０．３ｍｍ程度の細線同軸ケーブルを同軸コネクタの雌コネクタおよび雄コネクタに結線する場合、特許文献３に示される組立作業と同様に、細線同軸ケーブルの芯線部をそのコネクタの内部コンタクトに圧着し半田付け固定する作業を必要とし、加えて、それらをコネクタの絶縁体の中に入れた後、コネクタの外部コンタクトに入れ、外部コンタクトの２箇所を細線同軸ケーブルのシールド部に対し圧着するといった作業も必要とされる場合がある。従って、アンテナ基板接続ユニットにおける同軸ケーブルおよび同軸コネクタの結線作業においては、その工数が比較的多いので煩雑な作業となるという問題を伴う。 In the connection of the antenna substrate connection unit described above, for example, when connecting a thin coaxial cable having a diameter of about 0.3 mm to a female connector and a male connector of a coaxial connector, It is necessary to crimp the core part of the coaxial cable to the internal contact of the connector and solder and fix it. In addition, after putting them in the insulator of the connector, put them in the external contact of the connector, There is a case where an operation of crimping the portion to the shield portion of the thin coaxial cable is also required. Therefore, the coaxial cable and coaxial connector connection work in the antenna substrate connection unit involves a problem that the man-hours are relatively large, which is a complicated work.
　以上の問題点を考慮し、本発明は、アンテナ基板およびアンテナ基板に接続される接続用基板を相互に接続するアンテナ基板接続ユニットであって、アンテナ基板接続ユニットの薄型化を図ることができ、しかも、アンテナ基板およびアンテナ基板に接続される接続用基板相互間の結線作業を簡略化できるアンテナ基板接続ユニットを提供することを目的とする。 In view of the above problems, the present invention is an antenna substrate connection unit for connecting an antenna substrate and a connection substrate connected to the antenna substrate to each other, and the antenna substrate connection unit can be thinned. Moreover, it is an object of the present invention to provide an antenna substrate connection unit that can simplify the connection work between the antenna substrate and the connection substrates connected to the antenna substrate.

　カバー部材１８における右側の孔１８ａと左側の孔１８ａとの間には、図１に示されるように、二個の窪み１８ｄが所定の間隔をもって形成されている。二個の窪み１８ｄの中心間距離は、上述のフレキシブル配線基板１０の一対のコンタクトパッド１０ｓａの中心間距離と一致している。カバー部材１８の内周面における各窪み１８ｄに対応する部分は、コンタクトパッド１０ｓａに当接しフレキシブル配線基板１０を案内するように隆起部１８ｄｐを部分的に形成している。 Between the right hole 18a and the left hole 18a in the cover member 18, two depressions 18d are formed at a predetermined interval as shown in FIG. The distance between the centers of the two depressions 18d is equal to the distance between the centers of the pair of contact pads 10sa of the flexible wiring board 10 described above. A portion corresponding to each recess 18 d on the inner peripheral surface of the cover member 18 partially forms a raised portion 18 dp so as to contact the contact pad 10 sa and guide the flexible wiring board 10.
　カバー部材１８と一体に形成される係止部となる一対の突起片１８ｇａおよび１８ｇｂの相互間距離は、上述のフレキシブル配線基板１０の段差部１０Ｅの相互間距離と一致している。一対の突起片１８ｇａおよび１８ｇｂの先端は、それぞれ、カバー部材１８が最下端位置まで押し下げられる場合、図２に示されるように、コネクタ本体２０の窪み２０ＧＡおよび２０ＧＢに嵌合される。その際、カバー部材１８と一体に形成される折曲部１８ｇｃは、コネクタ本体２０のポスト２０ＲＰＢおよび２０ＬＰＢ相互間に挿入される。 The distance between the pair of protruding pieces 18ga and 18gb, which are locking portions formed integrally with the cover member 18, is the same as the distance between the step portions 10E of the flexible wiring board 10 described above. The ends of the pair of protrusion pieces 18ga and 18gb are fitted into the recesses 20GA and 20GB of the connector main body 20 as shown in FIG. 2 when the cover member 18 is pushed down to the lowest position. At that time, the bent portion 18gc formed integrally with the cover member 18 is inserted between the posts 20RPB and 20LPB of the connector body 20.
　コネクタ本体２０は、図５に拡大されて示されるように、例えば、樹脂材料で成形され、ケーブル収容部２０Ａを中央部に有している。ケーブル収容部２０Ａは、その三方が互いに略平行に所定の間隔をもって形成される側壁２０ＲＷおよび２０ＬＷと、側壁２０ＲＷの一端と側壁２０ＬＷの一端とを連結する連結壁２０ＢＷとにより囲まれるとともに、上方がカバー部材１８により覆われることにより形成されている。コネクタ本体２０における上述のケーブルスロットの下部を形成する前壁２０ＦＷの平坦部には、一対の突起片１８ｇａおよび１８ｇｂがそれぞれ嵌合される窪み２０ＧＡおよび２０ＧＢが形成されている。 The connector main body 20 is formed of, for example, a resin material and has a cable housing portion 20A in the center as shown in an enlarged manner in FIG. The cable housing portion 20A is surrounded by side walls 20RW and 20LW that are formed in substantially parallel to each other at a predetermined interval, and a connecting wall 20BW that connects one end of the side wall 20RW and one end of the side wall 20LW, and the upper side is It is formed by being covered with a cover member 18.

　側壁２０ＲＷおよび２０ＬＷの両端には、それぞれ、ポスト２０ＲＰＡおよび２０ＲＰＢ、２０ＬＰＡおよび２０ＬＰＢが形成されている。 Posts 20RPA and 20RPB, 20LPA and 20LPB are formed on both ends of the side walls 20RW and 20LW, respectively.
　側壁２０ＲＷおよび２０ＬＷは、互いに同一の構造を有するので側壁２０ＲＷについて説明し、側壁２０ＬＷについての説明を省略する。 Since the side walls 20RW and 20LW have the same structure, the side wall 20RW will be described and the description of the side wall 20LW will be omitted.
　側壁２０ＲＷは、ポスト２０ＲＰＡとポスト２０ＲＰＢとの間における略中央部に切欠部２０ＧＤを有している。図５において、切欠部２０ＧＤの左側部分には、側壁２０ＲＷの下端近傍に形成される金属製の爪部２０ＲＮ２と、それに比べて幅の狭い爪部２０ＲＮ１とが隣接して形成されている。爪部２０ＲＮ１の位置は、側壁２０ＲＷにおける爪部２０ＲＮ２に位置に比べて若干高く上端にある。これにより、爪部２０ＲＮ１および爪部２０ＲＮ２は、爪部２０ＲＮ１の先端と爪部２０ＲＮ２の先端とが、二段で互いに平行となるように形成されている。 Side wall 20RW has notch 20GD in the approximate center between post 20RPA and post 20RPB. In FIG. 5, a metal claw portion 20RN2 formed near the lower end of the side wall 20RW and a claw portion 20RN1 having a narrower width are formed adjacent to the left side portion of the cutout portion 20GD. The position of the claw portion 20RN1 is slightly higher than the position of the claw portion 20RN2 on the side wall 20RW and is at the upper end. Thereby, claw part 20RN1 and claw part 20RN2 are formed so that a tip of claw part 20RN1 and a tip of claw part 20RN2 may be mutually parallel in two steps.
　図５において、切欠部２０ＧＤの右側部分には、側壁２０ＲＷの下端近傍に形成される金属製の爪部２０ＲＮ３と、それに比べて幅の狭い爪部２０ＲＮ４とが隣接して形成されている。爪部２０ＲＮ４の位置は、側壁２０ＲＷにおける爪部２０ＲＮ３に位置に比べて若干高く上端にある。これにより、爪部２０ＲＮ４および爪部２０ＲＮ３は、爪部２０ＲＮ４の先端と爪部２０ＲＮ３の先端とが、二段で互いに平行となるように形成されている。その際、爪部２０ＲＮ１の先端と爪部２０ＲＮ４の先端とが共通の平面上にあり、爪部２０ＲＮ２の先端と爪部２０ＲＮ３の先端とが共通の平面上にある。金属製の爪部２０ＲＮ２および爪部２０ＲＮ３は、例えば、コネクタ本体２０とインサート成形されている。 In FIG. 5, a metal claw portion 20RN3 formed near the lower end of the side wall 20RW and a claw portion 20RN4 having a narrower width are formed adjacent to the right side portion of the cutout portion 20GD. The position of the claw portion 20RN4 is slightly higher than the position of the claw portion 20RN3 on the side wall 20RW and is at the upper end. Thereby, claw part 20RN4 and claw part 20RN3 are formed so that a tip of claw part 20RN4 and a tip of claw part 20RN3 may be mutually parallel in two steps. At that time, the tip of the claw portion 20RN1 and the tip of the claw portion 20RN4 are on a common plane, and the tip of the claw portion 20RN2 and the tip of the claw portion 20RN3 are on a common plane. The metal claw portion 20RN2 and the claw portion 20RN3 are insert-molded with the connector body 20, for example.
　一方、側壁２０ＬＷにおけるポスト２０ＬＰＡとポスト２０ＬＰＢとの間には、切欠部２０ＧＤ、および、爪部２０ＲＮ１～２０ＲＮ４に対応する切欠部２０ＧＥ、および、爪部２０ＬＮ１～２０ＬＮ４が形成されている。 On the other hand, between the post 20LPA and the post 20LPB on the side wall 20LW, a notch 20GD, a notch 20GE corresponding to the claws 20RN1 to 20RN4, and a claw 20LN1 to 20LN4 are formed.
　ケーブル収容部２０Ａには、複数のコンタクト端子２２ａｉ（ｉ＝１～３）が互いに平行にＹ座標軸に沿って所定の間隔で配列されている。コンタクト端子２２ａｉは、例えば、インサート成形により、コネクタ本体２０と一体化される。コンタクト端子２２ａｉは、湾曲状の接点部２２ｃを先端に有する可動部２２ｍと、通信制御用基板１４に半田付け固定される固定端子部２２ｆを有する固定部とから構成される。 In the cable housing portion 20A, a plurality of contact terminals 22ai (i = 1 to 3) are arranged in parallel with each other at a predetermined interval along the Y coordinate axis. The contact terminal 22ai is integrated with the connector body 20 by, for example, insert molding. The contact terminal 22ai includes a movable portion 22m having a curved contact portion 22c at the tip, and a fixed portion having a fixed terminal portion 22f that is fixed to the communication control board 14 by soldering.
　フレキシブル配線基板１０の接続端部がケーブル収容部２０Ａに挿入されるとき、３本のうち両端にある２本のコンタクト端子２２ａｉの接点部２２ｃは、それぞれ、図１１に拡大されて示されるように、コンタクトパッド１０ＧＰＡ，１０ＧＰＢに当接される。また、中央に配置される残りのコンタクト端子２２ａｉの接点部２２ｃは、コンタクトパッド１０ＳＰに当接される。固定端子部２２ｆは、連結壁２０ＢＷから外方に向けて突出している。これにより、両端にあるコンタクト端子２２ａｉの固定端子部２２ｆは、基板の接地ライン用導体パターンに接続され、中央に配置されるコンタクト端子２２ａｉは、信号ライン用導体パターンに接続されることとなる。その際、コンタクトパッド１０ＧＰＡ，１０ＧＰＢは、カバー部材１８の窪み１８ｄに対応する隆起部１８ｄｐに当接している一対のコンタクトパッド１０ｓａおよび絶縁性基材１０Ｍ内のめっきスルーホール１０ＴＨを介してカバー部材１８に電気的に接続されている。斯かる場合において、フレキシブル配線基板１０の接続端部におけるコンタクトパッド１０ＳＰに接続される信号ラインが、両脇の接地ラインおよびカバー部材１８により障害電波に対し遮蔽される、即ち、ＥＭＩシールドされることとなる。なお、金属製のカバー部材１８に端子部を形成し、その端子部を通信制御用基板１４の接地ライン用導体パターンに半田付け固定してもよい。または、上述したように、側壁２０ＲＷまたは側壁２０ＬＷの側壁に形成される爪部２０ＲＮ２、２０ＲＮ３、爪部２０ＬＮ２および爪部２０ＬＮ３のすべてを金属材料で形成し、それらを通信制御用基板１４の接地ライン用導体パターンに接続されるように構成されてもよい。さらに、通信制御用基板１４の接地ライン用導体パターンに接続されるコンタクトパッド１０ＧＰＡ、１０ＧＰＢに当接するコンタクト端子２２ａｉと、爪部２０ＲＮ２、２０ＲＮ３、爪部２０ＬＮ２および爪部２０ＬＮ３のすべてとを一体化するよう形成されてもよい。これにより、カバー部材１８が、基板の接地ライン用導体パターンとの接続が強固になり、より安定したＥＭＩシールドとなる。 When the connection end portion of the flexible wiring board 10 is inserted into the cable housing portion 20A, the contact portions 22c of the two contact terminals 22ai at both ends of the three are expanded and shown in FIG. The contact pads 10GPA and 10GPB are brought into contact with each other. Further, the contact portions 22c of the remaining contact terminals 22ai arranged at the center are in contact with the contact pads 10SP. The fixed terminal portion 22f protrudes outward from the connecting wall 20BW. Thus, the fixed terminal portions 22f of the contact terminals 22ai at both ends are connected to the ground line conductor pattern of the substrate, and the contact terminals 22ai arranged in the center are connected to the signal line conductor pattern. At that time, the contact pads 10GPA and 10GPB cover the cover member 18 via a pair of contact pads 10sa that are in contact with the raised portions 18dp corresponding to the depressions 18d of the cover member 18 and the plated through holes 10TH in the insulating base material 10M. Is electrically connected. In such a case, the signal line connected to the contact pad 10SP at the connection end of the flexible wiring board 10 is shielded against the disturbing radio wave by the ground line on both sides and the cover member 18, that is, EMI shielded. It becomes. Note that a terminal portion may be formed on the metal cover member 18 and the terminal portion may be soldered and fixed to the ground line conductor pattern of the communication control board 14. Alternatively, as described above, the claw portions 20RN2, 20RN3, the claw portion 20LN2, and the claw portion 20LN3 formed on the side wall 20RW or the side wall of the side wall 20LW are all formed of a metal material, and are formed on the ground line of the communication control board 14 It may be configured to be connected to the conductor pattern for use. Further, the contact terminals 22ai contacting the contact pads 10GPA and 10GPB connected to the ground line conductor pattern of the communication control board 14 are integrated with the claw portions 20RN2, 20RN3, the claw portions 20LN2, and the claw portions 20LN3. It may be formed as follows. As a result, the cover member 18 is firmly connected to the ground line conductor pattern of the substrate, and the EMI shield becomes more stable.
　斯かる構成において、アンテナ基板接続ユニットを組み立てるにあたり、先ず、２個のケーブル用コネクタ１６のコンタクト端子２２ａｉの固定端子部２２ｆが、それぞれ、アンテナ基板１２および通信制御用基板１４における所定位置に半田付け固定される。次に、図１に示されるように、各ケーブル用コネクタ１６において、カバー部材１８がコネクタ本体２０に対し第１の位置の状態で取付けられる。第１の位置とは、カバー部材１８の係止片部１８ＲＦ１、１８ＲＦ２、１８ＬＦ１、および、１８ＬＦ２が、それぞれ、爪部２０ＲＮ１，２０ＲＮ４、２０ＬＮ１、および、２０ＬＮ４に係止されている状態をいう。その際、フレキシブル配線基板１０の接続端部（拡大部）が、一対の突起片１８ｇａ、１８ｇｂに干渉することなく、ケーブルスロットを通じてケーブル収容部２０Ａに挿入可能とされる。 In such a configuration, when assembling the antenna board connection unit, first, the fixed terminal portions 22f of the contact terminals 22ai of the two cable connectors 16 are soldered to predetermined positions on the antenna board 12 and the communication control board 14, respectively. Fixed. Next, as shown in FIG. 1, in each cable connector 16, the cover member 18 is attached to the connector main body 20 in the first position. The first position refers to a state in which the locking pieces 18RF1, 18RF2, 18LF1, and 18LF2 of the cover member 18 are locked to the claw portions 20RN1, 20RN4, 20LN1, and 20LN4, respectively. At that time, the connection end portion (enlarged portion) of the flexible wiring board 10 can be inserted into the cable housing portion 20A through the cable slot without interfering with the pair of protrusion pieces 18ga and 18gb.
　続いて、図１に示されるように、フレキシブル配線基板１０のコンタクトパッド１０ｓａがカバー部材１８の内周面に向き合う状態で、図６に示されるように、フレキシブル配線基板１０の接続端部（拡大部）が、ケーブルスロットを通じてケーブル収容部２０Ａに載置される。その後、図２に示されるように、カバー部材１８がコネクタ本体２０に対し第２の位置まで押し下げられる。第２の位置とは、カバー部材１８の係止片部１８ＲＦ１、１８ＲＦ２、１８ＬＦ１、および、１８ＬＦ２が、それぞれ、爪部２０ＲＮ２，２０ＲＮ３、２０ＬＮ２、および、２０ＬＮ３に係止されている状態をいう。その際、フレキシブル配線基板１０の段差部１０Ｅが、突起片１８ｇａおよび１８ｇｂにより係止するようケーブル収容部２０Ａに位置決めされるとともに、拘束される。これにより、フレキシブル配線基板１０の両端にある接続端部が、それぞれ、各基板のケーブル用コネクタ１６に接続されるのでアンテナ基板接続ユニットの組み立てが終了することとなる。 Subsequently, as shown in FIG. 1, with the contact pads 10 sa of the flexible wiring substrate 10 facing the inner peripheral surface of the cover member 18, as shown in FIG. Is mounted on the cable housing portion 20A through the cable slot. Thereafter, as shown in FIG. 2, the cover member 18 is pushed down to the second position with respect to the connector main body 20. The second position refers to a state where the locking pieces 18RF1, 18RF2, 18LF1, and 18LF2 of the cover member 18 are locked to the claw portions 20RN2, 20RN3, 20LN2, and 20LN3, respectively. At that time, the stepped portion 10E of the flexible wiring board 10 is positioned and restrained by the cable housing portion 20A so as to be locked by the protruding pieces 18ga and 18gb. As a result, the connection end portions at both ends of the flexible wiring board 10 are respectively connected to the cable connectors 16 of the respective boards, so that the assembly of the antenna board connection unit is completed.
　従って、アンテナ基板接続ユニットの組み立てが、アンテナ回路基板および通信制御回路基板相互間の結線作業を、フレキシブル配線基板１０の半田付け作業等を必要とすることなく容易に簡略化でき、しかも、薄板状のフレキシブル配線基板１０によりケーブル用コネクタ１６を接続するのでアンテナ基板接続ユニットの薄型化を図ることができる。 Therefore, the assembly of the antenna board connecting unit can easily simplify the wiring work between the antenna circuit board and the communication control circuit board without requiring the soldering work of the flexible wiring board 10 and the like. Since the cable connector 16 is connected by the flexible wiring board 10, the antenna board connecting unit can be thinned.
　一方、フレキシブル配線基板１０の接続端部をケーブル用コネクタ１６から取り外すにあたっては、図示が省略される治具の先端が、カバー部材１８の開口部１８ａ，コネクタ本体２０の切欠部２０ＧＤ、２０ＧＥに貫通された後、治具によりリリース用ガイド片ＲＧＰが係止片部１８ＲＦ１～１８ＬＦ２を伴ってコネクタ本体２０から離隔する方向に押し広げられる。これにより、カバー部材１８がコネクタ本体２０から取り外されるので
フレキシブル配線基板１０の接続端部がケーブル用コネクタ１６から取り外し可能とされる。 On the other hand, when removing the connection end of the flexible wiring board 10 from the cable connector 16, the tip of a jig (not shown) penetrates the opening 18a of the cover member 18 and the notches 20GD and 20GE of the connector body 20. After that, the release guide piece RGP is pushed and spread in the direction away from the connector main body 20 with the locking piece portions 18RF1 to 18LF2 by the jig. Thereby, since the cover member 18 is removed from the connector main body 20, the connection end portion of the flexible wiring board 10 can be detached from the cable connector 16.
　なお、上述の例において、カバー部材１８は、取り外し可能とされるが、斯かる例に限られることなく、例えば、フレキシブル配線基板１０が接続された後、カバー部材１８の一部が、アンテナ回路基板および通信制御回路基板における接地ライン用導体パターンに半田付けにより固定されてもよい。 In the above-described example, the cover member 18 can be removed. However, the present invention is not limited to such an example. For example, after the flexible wiring board 10 is connected, a part of the cover member 18 is an antenna circuit. You may fix to the conductor pattern for ground lines in a board | substrate and a communication control circuit board by soldering.
