Description

本発明は、携帯電話、デジタルカメラ、ノートパソコン等の電気機器に配線材として用いられる極細同軸ケーブルアセンブリ、及び極細同軸ケーブルの端末構造に関する。 The present invention relates to a micro coaxial cable assembly used as a wiring material in an electric device such as a mobile phone, a digital camera, and a laptop computer, and a terminal structure of the micro coaxial cable.

近年、携帯電話、デジタルカメラ、ノートパソコン等の電気機器にあっては、前記電気機器の液晶表示部の解像度を高める等の理由により、ノイズの影響の少ない極細同軸ケーブルアセンブリが配線材として用いられるようになってきている。 In recent years, in electrical devices such as mobile phones, digital cameras, and notebook computers, a micro coaxial cable assembly that is less affected by noise is used as a wiring material for reasons such as increasing the resolution of a liquid crystal display unit of the electrical device. It has become like this.

次に、一般的な極細同軸ケーブルアセンブリについて図８及び図９を参照して説明する。ここで、図８は、一般的な極細同軸ケーブルを示す図であって、図９は、極細同軸ケーブルの断面図である。 Next, a general micro coaxial cable assembly will be described with reference to FIGS. Here, FIG. 8 is a view showing a general micro coaxial cable, and FIG. 9 is a cross-sectional view of the micro coaxial cable.

図８に示すように、一般的な極細同軸ケーブルアセンブリ１は、携帯電話等の電気機器における第１電子部品（図示省略）と第２電子部品（図示省略）を電気的に接続するために用いられるものであって、集合した多数本の極細同軸ケーブル３を備えている。また、図９に示すように、極細同軸ケーブル３は、中心導体５と、この中心導体５を覆う絶縁層７と、この絶縁層７の外周部に設けられかつ中心導体５をシールドする横巻き外部導体９と、この横巻き外部導体９の回りを覆うシース１１とを備えている。ここで、極細同軸ケーブル３の外径は、０．３ｍｍ程度が主流になっているが、これよりも太径或いは細径のものも製作されている。 As shown in FIG. 8, a general micro coaxial cable assembly 1 is used to electrically connect a first electronic component (not shown) and a second electronic component (not shown) in an electric device such as a mobile phone. A plurality of micro coaxial cables 3 assembled. As shown in FIG. 9, the micro coaxial cable 3 includes a center conductor 5, an insulating layer 7 that covers the center conductor 5, and a lateral winding that is provided on the outer periphery of the insulating layer 7 and shields the center conductor 5. An outer conductor 9 and a sheath 11 covering the periphery of the laterally wound outer conductor 9 are provided. Here, the outer diameter of the ultra-fine coaxial cable 3 is mainly about 0.3 mm, but a thicker or smaller diameter is also manufactured.

図８に示すように、多数本の極細同軸ケーブル３の一端部には、極細同軸ケーブル専用の第１コネクタ１３が連結されており、この第１コネクタ１３は、前記第１電子部品における第１相手コネクタ１５に嵌合可能である。また、多数本の極細同軸ケーブル３の他端部には、極細同軸ケーブル専用の第２コネクタ１７が連結されており、この第２コネクタ１７は、前記第２電子部品における第２相手コネクタ１９に嵌合可能である。ここで、第１コネクタ１３及び第２コネクタ１７における極細同軸ケーブル３の接続ピッチは、０．４ｍｍが主流になっている。 As shown in FIG. 8, a first connector 13 dedicated to a micro coaxial cable is connected to one end of a large number of micro coaxial cables 3, and the first connector 13 is a first connector in the first electronic component. The mating connector 15 can be fitted. A second connector 17 dedicated to the fine coaxial cable is connected to the other end of the multiple fine coaxial cables 3, and the second connector 17 is connected to the second mating connector 19 in the second electronic component. Can be mated. Here, the connection pitch of the micro coaxial cable 3 in the first connector 13 and the second connector 17 is mainly 0.4 mm.

ところで、前記電気機器の伝送容量の増加に伴って、極細同軸ケーブルアセンブリ１における極細同軸ケーブル３の本数を増える傾向にある。一方、極細同軸ケーブル３の外径を考慮すると、第１コネクタ１３及び第２コネクタ１７における接続ピッチも０．４ｍｍより小さくすることは、現状は極めて困難である。そのため、極細同軸ケーブルアセンブリ１における極細同軸ケーブル３の本数が増えると（例えば３０本を越えると）、第１コネクタ１３又は第２コネクタ１７の幅が拡大して、第１コネクタ１３又は第２コネクタ１７の搭載面積が大きくなって、前記電気機器の小型化の障害になるという問題がある。 By the way, with the increase in the transmission capacity of the electrical equipment, the number of the micro coaxial cables 3 in the micro coaxial cable assembly 1 tends to increase. On the other hand, considering the outer diameter of the micro coaxial cable 3, it is extremely difficult to reduce the connection pitch of the first connector 13 and the second connector 17 to less than 0.4 mm. Therefore, when the number of the micro coaxial cables 3 in the micro coaxial cable assembly 1 increases (for example, exceeds 30), the width of the first connector 13 or the second connector 17 increases, and the first connector 13 or the second connector. There is a problem that the mounting area of 17 becomes large and becomes an obstacle to miniaturization of the electric device.

次に、第１の最良の形態の作用について説明する。 Next, the operation of the first best mode will be described.

第１コネクタ４７は、多数本の第１パターン側端子４９が対応関係にある第１接続パターン４５の先端部４５ｂに電気的に接続するように構成されてあって、第１フレキシブル回路基板４３は、多数本の第１接続パターン４５における先端部４５ｂのピッチが基端部４５ａのピッチよりも小さくなるように構成されているため、極細同軸ケーブルアセンブリ２１における極細同軸ケーブル３９の本数が増えても、第１コネクタ４７における第１パターン側端子４９のピッチ（接続ピッチ）を小さくして、第１コネクタ４７の幅の拡大を十分に抑えることができる。 The first connector 47 is configured to be electrically connected to the distal end portion 45b of the first connection pattern 45 in which a large number of first pattern side terminals 49 are in a corresponding relationship, and the first flexible circuit board 43 is Since the pitch of the distal end portions 45b in the multiple first connection patterns 45 is configured to be smaller than the pitch of the proximal end portions 45a, even if the number of the micro coaxial cables 39 in the micro coaxial cable assembly 21 increases. The pitch of the first pattern side terminals 49 in the first connector 47 (connection pitch) can be reduced to sufficiently suppress the expansion of the width of the first connector 47.

また、第１フレキシブル回路基板４３の両面側には極細同軸ケーブル３９と同数の第１接続パターン４５を有しているため、極細同軸ケーブルアセンブリ２１における極細同軸ケーブル３９の本数が増えても、第１フレキシブル回路基板４３の幅を小さくすることができる。 In addition, since the same number of first connection patterns 45 as the fine coaxial cables 39 are provided on both sides of the first flexible circuit board 43, even if the number of the fine coaxial cables 39 in the fine coaxial cable assembly 21 increases, 1 The width of the flexible circuit board 43 can be reduced.

Since the substrate 55 is configured such that the pitch of the distal end portions 57b in the multiple second connection patterns 57 is smaller than the pitch of the proximal end portions 57a, the number of the micro coaxial cables 39 in the micro coaxial cable assembly 21 is the same.

また、第２フレキシブル回路基板５５の両面側には極細同軸ケーブル３９と同数の第２接続パターン５７を有しているため、極細同軸ケーブルアセンブリ２１における極細同軸ケーブル３９の本数が増えても、第２フレキシブル回路基板５５の幅を小さくすることができる。 In addition, since the second flexible circuit board 55 has the same number of second connection patterns 57 as the fine coaxial cables 39 on both sides, even if the number of the fine coaxial cables 39 in the fine coaxial cable assembly 21 increases, 2 The width of the flexible circuit board 55 can be reduced.

以上の如き、第１の最良の形態によれば、極細同軸ケーブルアセンブリ２１における極細同軸ケーブル３９の本数が増えても、第１コネクタ４７及び第２コネクタ５９における接続ピッチを小さくして、第１コネクタ４７及び第２コネクタ５９の幅の拡大を十分に抑えることができるため、第１コネクタ４７及び第２コネクタ５９の搭載面積を小さくして、携帯電話２３の小型化を促進することができる。 As described above, according to the first best mode, even if the number of the micro coaxial cables 39 in the micro coaxial cable assembly 21 is increased, the connection pitch between the first connector 47 and the second connector 59 is reduced, and the first Since the expansion of the width of the connector 47 and the second connector 59 can be sufficiently suppressed, the mounting area of the first connector 47 and the second connector 59 can be reduced, and the downsizing of the mobile phone 23 can be promoted.

また、極細同軸ケーブルアセンブリ２１における極細同軸ケーブル３９の本数が増えても、第１フレキシブル回路基板４３及び第２フレキシブル回路基板５５の幅を小さくすることができるため、携帯電話２３の狭いスペースを利用して、極細同軸ケーブルアセンブリ２１を搭載することができる Further, even if the number of micro coaxial cables 39 in the micro coaxial cable assembly 21 is increased, the widths of the first flexible circuit board 43 and the second flexible circuit board 55 can be reduced, so that the narrow space of the mobile phone 23 is used. Then, the micro coaxial cable assembly 21 can be mounted.

In particular, since the first flexible circuit board 71 has the same number of first connection patterns 73 (73 ′) as the fine coaxial cables 67 on both sides, the number of the fine coaxial cables 67 in the fine coaxial cable assembly 65 increases. However, the width of the first flexible circuit board 71 can be further reduced.

同様に、第２コネクタ８７は、多数本の第２パターン側端子８９が対応関係にある第２接続パターン８５（８５’）の先端部８５ｂ（８５’ｂ）に電気的に接続するように構成されてあって、第２フレキシブル回路基板８３は、多数本の表側の第２接続パターン８５の基端部８５ａと多数本の裏側の第２接続パターン８５’の基端部８５’ａが複数列に並ぶように構成されているため、極細同軸ケーブルアセンブリ６５における極細同軸ケーブル６７の本数が増えても、第２コネクタ８７の幅の拡大を十分に抑えることができると共に、第２フレキシブル回路基板８３の幅を小さくすることができる。特に、第２フレキシブル回路基板８３の両面側には極細同軸ケーブル６７と同数の第２接続パターン８５（８５’）を有しているため、極細同軸ケーブルアセンブリ６５における極細同軸ケーブル６７の本数が増えても、第２フレキシブル回路基板８３の幅をより小さくすることができる。 Similarly, the second connector 87 is configured to be electrically connected to the distal end portion 85b (85′b) of the second connection pattern 85 (85 ′) in which a large number of second pattern side terminals 89 have a corresponding relationship. The second flexible circuit board 83 includes a plurality of rows of base end portions 85a of the plurality of front-side second connection patterns 85 and base end portions 85′a of the plurality of back-side second connection patterns 85 ′. Therefore, even if the number of the micro coaxial cables 67 in the micro coaxial cable assembly 65 increases, the width of the second connector 87 can be sufficiently suppressed, and the second flexible circuit board 83 can be suppressed. The width of can be reduced. In particular, since the second flexible circuit board 83 has the same number of second connection patterns 85 (85 ′) as the fine coaxial cables 67 on both sides, the number of the fine coaxial cables 67 in the fine coaxial cable assembly 65 increases. However, the width of the second flexible circuit board 83 can be further reduced.

以上の如き、第２の最良の形態によれば、極細同軸ケーブルアセンブリ６５における極細同軸ケーブル６７の本数が増えても、第１コネクタ７５及び第２コネクタ８７の幅の拡大を十分に抑えることができるため、第１コネクタ７５及び第２コネクタ８７の搭載面積を小さくして、携帯電話２３の小型化を促進することができる。 As described above, according to the second best mode, even if the number of the micro coaxial cables 67 in the micro coaxial cable assembly 65 is increased, the expansion of the widths of the first connector 75 and the second connector 87 can be sufficiently suppressed. Therefore, the mounting area of the first connector 75 and the second connector 87 can be reduced, and the downsizing of the mobile phone 23 can be promoted.

また、極細同軸ケーブルアセンブリ６５における極細同軸ケーブル６７の本数が増えても、第１フレキシブル回路基板７１及び第２フレキシブル回路基板８３の幅をより小さくすることができるため、携帯電話２３の狭いスペースを利用して、極細同軸ケーブルアセンブリ６５を搭載することができる。 Further, even if the number of the micro coaxial cables 67 in the micro coaxial cable assembly 65 is increased, the widths of the first flexible circuit board 71 and the second flexible circuit board 83 can be further reduced. Utilizing this, it is possible to mount the micro coaxial cable assembly 65.
