Description of the Invention: Technical Field The present invention relates to a cable harness, a cable harness with a connector, and a cable harness, and has a plurality of coaxial cables and insulation arranged in parallel. The cable, the external conductor system of the coaxial cable is grounded. [Prior Art] In recent years, in addition to the miniaturization and weight reduction of such electronic devices, high-speed and high-quality images have been demanded due to the spread of mobile phones and small video cameras. In order to meet these needs, the ultra-fine coaxial cable is used in the connection between the machine body and the liquid crystal display unit or the wiring in the machine, and a plurality of coaxial cables are integrated and integrated due to the ease of wiring. Cable harness. The coaxial cable used for the cable harness is configured such that the center conductor, the inner insulator, the outer conductor, and the outer portion are arranged coaxially from the inside. The center conductor is formed by, for example, kneading seven copper alloy wires, and the outer surface thereof is covered with an insulating material such as Teflon (registered trademark) resin to form an internal insulator. The outer conductor disposed on the outer peripheral surface of the inner insulator is formed, for example, by winding a copper alloy wire into a spiral shape, and on the outer surface, for example, two sheets of the polyester tape are stacked and wound to be welded to each other as an outer cover. Further, the copper vapor deposition surface of the copper vapor deposition tape may be wound around the outer surface of the outer conductor as the inner side, or the outer layer may be wound with two layers opposite to the winding direction of the copper alloy wire. Can be a braided construction. Various forms are proposed on the cable harness. For example, it is known that many 200947473 multiple signal transmission coaxial cables and a plurality of power transmission (power supply) cables are connected by heat fusion or adhesive. It is formed in a shape (for example, refer to Patent Document 1). In addition, for example, the signal cable is coaxially arranged at a predetermined pitch by a coaxial cable and a power supply cable, and the tape having the adhesive layer is attached to the two sides of the cable, thereby forming an integrated cable harness. It is known (for example, refer to Patent Document 2). [Patent Document 1] Japanese Laid-Open Patent Publication No. JP-A-62-8661 No. JP-A No. JP-A No. 2000-322943A SUMMARY OF INVENTION [Problems to be Solved by the Invention] However, as described above As described above, electronic devices such as mobile phones and small video cameras have been designed to further improve the performance, thereby increasing the amount of information processed. On the other hand, there is also a demand for miniaturization and weight reduction, so that the cable harness for such an electronic device is also required to be assembled at a high density, and there is a tendency that the cable harness is formed by a very thin coaxial cable. Since the coaxial cable has a center conductor, an internal insulator, an outer conductor, and an outer casing, the center conductor has a small cross-sectional area. As in the cable of Patent Document 2, when a coaxial cable is used as a power supply cable, The necessary current is used to make a number of coaxial cables. Further, the end portion of the cable harness is electrically connected to a connector or a substrate or the like which is soldered to a terminal arranged at a predetermined pitch. Therefore, it is required that all the cables constituting the cable harness are arranged at a predetermined pitch and arranged at the terminals. In particular, when the cable is extremely thin, the arrangement pitch of each cable is also small, and even if the position deviation of .200947473 is a sub-centimeter unit, it is likely to cause a problem. Therefore, it is required that the cables constituting the cable harness are arranged with high precision. Therefore, it is important that the cables are fixed at a predetermined pitch on the ground rod. Further, in the cable harness other than the above-mentioned Patent Documents 1, 2, the signal cable and the power supply cable are arranged separately, and only the signal cable is connected to the ground rod and fixed, but at this time, the end portion is performed. When the operation is performed, the signal cable and the power supply cable are required to be separately positioned, so that workability is poor. © Accordingly, it is an object of the present invention to provide a cable harness, a cable harness with a connector, and a cable harness connection structure, including: a cable for a signal cable and a power cable, which is easy and correct A very thin coaxial cable that connects the connector terminals of the end portion and the like is connected. [Means for Solving the Problem] A cable harness according to the present invention which solves the above-described problems is characterized in that a plurality of coaxial cables and insulated cables are arranged in parallel, and a plurality of coaxial cables have a center conductor and a configuration An inner insulator on the outer circumference of the center conductor, an outer conductor disposed on the outer circumference of the inner insulator, and an outer conductor disposed on the outer circumference of the outer conductor; the insulated cable has a center conductor and is disposed on the center conductor The exposed portion of the outer circumference is fixed to the common ground rod by the exposed portion of the outer conductor of the coaxial cable and the insulated cable, and the exposed portion is electrically connected to the ground rod. In the cable harness of the present invention, the outer diameter Di of the insulated cable and the outer diameter Dc of the outer conductor portion of the coaxial cable are preferably .200947473

發明相關的纜線線束，上述同軸纜線之各中心導體及上述 絕緣纜線之中心導體，係接續到設置於電性電路之接續端 子，作爲特徵。 此外，此纜線線束的接續構造，係爲對例如印刷基板（FPC : 軟性印刷電路、PWB :印刷配線板等）的接續構造。 [發明之效果] 包含於本發明之纜線線束的絕緣纜線係由中心導體及外 被構成，因此容易確保中心導體之截面積爲大之構造，而 〇 可滿足作爲電源用纜線之性能。 又，同軸纜線之外部導體及絕緣纜線之外被係被挾持於 接地棒上固定，因此使端末部分對連接器端子等接續之時 • 不致有各纜線之排列狀態混亂之事。 具備本發明之纜線線束的附有連接器之纜線線束，同軸 纜線之中心導體及絕緣纜線之各中心導體係高精度地接續 到連接器之接續端子，而爲電源供給性能優越可靠性高之 附有連接器的纜線線束。又，接續於本發明之纜線線束與 200947473 印刷基板等之纜線線束之接續構造亦可達成同樣的效果。 【實施方式】 以下，將針對本發明相關之纜線線束、附有連接器之纜 線線束及纜線線束之接續構造的實施形態之例進行說明° 第1圖是顯示本發明相關之纜線線束之例的圖’第1 (A) 圖是纜線線束之俯視圖，而第1(B)圖是從第1(A)圖中F方 向看去之端面圖。此外，在第1(A)圖中，爲了使圖面簡明 起見，省略後述之第2接地棒30之圖示。又，第5圖係第 © 1圖之箭號方向V附近之放大截面圖。 如第1圖所示，纜線線束1 0具有多數條之同軸纜線Π、 ' 及至少1條之絕緣纜線40，此等係配置成並列。 同軸纜線11係被使用作爲信號傳輸用之信號纜線。在本 實施形態中設置37條。 如第2圖所示，同軸纜線11具有：中心導體15、配設於 中心導體15之外周的內部絕緣體14、配設於內部絕緣體 14之外周的外部導體13、及配設於外部導體13之外周的 ® 絕緣性外被12，將此等配設爲同軸狀而構成。 根據例如AWG(美國線規）之規格，同軸纜線1 1係使用相 當於AWG44之纜線。AWG44之同軸纜線1 1，係中心導體 15爲例如外徑0.020mm之鍍銀銅合金的線材15a共7條加 以捻撚而形成。又，內部絕緣體14係由被覆於中心導體15 之外周面的例如PF A等之氟樹脂形成，藉由擠出的被覆形 成厚度0.04mm。又，外部導體13係將例如鏟錫的銅合金 的線材13a橫捲繞於內部絕緣體14之外周面而捲成螺旋 200947473 狀，形成外徑爲0.21mm。除此之外，外被12係由被覆於 外部導體13之外周面的例如PFA等之氟樹脂形成，AWG44 之情況，形成外徑爲0.26mm。 同軸纜線1 1之端部進行引線處理，從前端側依序爲中心 導體1 5、內部絕緣體1 4、外部導體1 3分別成階段地露出 預定長度。 又，絕緣纜線40在本實施形態中設置3條。 絕緣纜線40，如第3圖所示，具有中心導體4 1及配設於 〇 其外周之絕緣性的外被42，將此等配設爲同軸狀而構成。 絕緣纜線40，例如同軸纜線11爲相當於AWG44之尺寸 者的情況，係使用相當於AWG之規格中之AWG38的纜線， 中心導體4 1例如係將鍍錫的銅合金的線材4 1 a共7條加以 捻線而形成，外被42係由被覆於中心導體41之外周面的 例如PFA等之氟樹脂形成，形成外徑爲〇.21mm。中心導體 41之部分的直徑爲0.11mm，外被42的厚度爲0.05mm。外 被42之厚度係比AWG44之同軸纜線11的內部絕緣體14 ❸之厚度更厚。 絕緣纜線40係作爲電源供給用而使用之纜線，中心導體 41之截面積係爲同軸纜線11之中心導體15的截面積以上 者。絕緣纜線40係爲由中心導體4 1及外被42構成的構造， 因此容易確保中心導體41的截面積比同軸纜線11更大。 當絕緣纜線40之外被42形成與同軸纜線11之外部導體 13之層爲同等之外徑時，與同軸纜線11之外部導體π — 起宜藉由2個接地棒20, 30挾持而固定。此外被42對於將 -10- 200947473 接地棒20，30固定於同軸纜線U及絕緣纜線40之時的熱 具有充分的厚度，使得外被42熔融而不致無法維持其絕緣 性能。使用脈衝加熱將同軸纜線11之外部導體13及絕緣 纜線40銲接到接地棒20，30而固定的情況’絕緣纜線40 之外被42宜作成爲〇.〇3mm以上之厚度。使用熔點230°C 左右之低熔點銲材的話’即使將外被42爲0.3mm之厚度的 絕緣纜線40銲接到接地棒20，30時’外被，42亦不熔融而 可保持絕緣特性。 〇 又，絕緣纜線40之端部亦進行引線處理’在長度方向之 端側，中心導體41露出預定長度（例如與同軸纜線11之中 心導體1 5同等長度）。 如第1圖所示，纜線線束10係使外部導體13及外被42 經由銲接而挾持於接地棒20, 30上’使得中心導體15及中 心導體41以預定之節距並列，且纜線線束1 〇及同軸纜線 1 1之位置可被固定。 接地棒20, 30係爲形成覆蓋所有的同軸纜線1 1之外部導 ® 體13及絕緣纜線40之外被42的長度之板。例如，係爲銅 板等之導電性之金屬板。 又，如第4圖所示，接地棒20，30之對向的面，係藉由 接合構件24而與各纜線11，40固定（參照第5圖）。接合構 件24方面，例如雖可使用板銲材，但是除了板銲材之外亦 可使用異方性導電薄膜（ACF)、非導電性薄膜（NCF)等。藉 由此等之接合構件24，接地棒20, 30與同軸纜線11之外 部導體13固接同時作電性接續。此外，即使在接合構件24 -11- 200947473 上使用非導電性薄膜之情況時，如第5圖所示，接合構件 24係埋入於接地棒20, 3 0與各纜線11，40之間隙的方式而 移動’因此外部導體13產生直接接觸於接地棒20，30之處 所’而達成接地棒20, 30與外部導體13之電性導通。如此， 各外部導體13可一起共通於接地棒20，30而進行接地。 又，雖然接合構件24對絕緣纜線40之外被42並未固接， 但是接合構件24係以埋入外被42之周圍而移動固化，因 此會妨礙絕緣纜線40朝正交於其軸方向之方向的移動。 〇 即，絕緣纜線40藉由接地棒20，30及接合構件24而固定 於至少軸方向以外。 由於同軸纜線11之外部導體13及絕緣纜線40之外被42 挾持固定在接地棒20，30，故能高精度地進行構成纜線線 束1 0之所有的纜線1 1，40之整理排列，且其排列狀態不致 混亂。因而，可正確地進行對纜線線束10之端末部份之連 接器端子等的接續。又，絕緣纜線40之中心導體41的截 面積可確保爲大，同時絕緣特性亦良好地維持，故作爲電 ® 源用纜線之性能係爲良好。 此外，雖然可採用：對同軸纜線11及絕緣纜線40之雙 方使用銲材之形態、對同軸纜線1 1使用銲材對絕緣纜線40 使用ACF或NCF之形態、對同軸纜線1 1及絕緣纜線40之 雙方使用使用ACF或NCF之形態，但是即使使用銲材之任 何形態將接合構件24(銲材）熱熔融之時’只要以脈衝加熱 等將接地棒20, 30 —次加熱即可。 以接地棒20，30挾持之部分的同軸纜線Π之外部導體 -12- 200947473 13的部分之外徑與絕緣纜線40之外被42的外徑之差，當 同軸纜線1 1爲AWG42或比AWG42更細之情況，至少可 容許至0.18mm。當同軸纜線11之外部導體13的部分之外 徑爲 0.17 mm之時，絕緣纜線40之外徑至少可容許至 0.35mm。若取兩者之直徑的比値的話，可容許較粗方之外 徑至少爲較細方之外徑的至少2倍左右。絕緣纜線40係作 爲電源用纜線而使用，因此中心導體41的截面積宜越大越 好（直徑大）。中心導體4 1粗化的結果，絕緣纜線40之外徑 比同軸纜線11之外部導體13的外徑更大也無妨。如第6 圖所示，對同軸纜線11之外部導體13的部分之外徑，可 容許絕緣纜線40之外徑較粗2倍左右。外徑差爲至0.18 mm 的話，調整接合構件24(銲材）之量，即可將以接地棒20, 30 挾持的部分藉由接合構件24而埋入。又，使絕緣纜線40 作成比同軸纜線1 1之外部導體1 3的部分之外徑更粗之情 況，只要將絕緣纜線40配置在並列之同軸纜線1 1的兩側 即可。藉此，同軸纜線1 1係配置在比同軸纜線1 1更粗的 絕緣纜線40之間。 其次，將針對上述纜線線束10之製造方法進行說明。 首先，將構成纜線線束10之所有的纜線11，40並列地配 置並藉由治具或接著帶等加以保持。各纜線11，40之配 置，例如第1圖所示，將自第1號心（第1圖之上端位置） 至第3號心作爲電源用絕緣纜線40，將自第4號心至第40 號心（第1圖之下端位置）作爲信號用同軸纜線1 1。又，所 有的纜線11, 40之端部的位置對準。 200947473 其後，將所有的纜線1 1，40之端部進行引線處理。 線處理係使用 YAG雷射或C〇2雷射等之雷射加工機 者，首先，調整CCh雷射之波長或強度且將同軸纜線 外被12從端部算起離開預定之距離的位置切斷，並將 側拉出而除去。此外，當發射C〇2雷射之時，預先使 部起預定長度加以彎曲等而退避，以避免射到絕緣纜凝 其次，調整YAG雷射之波長或強度且將同軸纜線 外部導體13從靠近外被切斷位置起預定長度之端部 © 置加以切斷，並將端部側之外部導體13拉出而除去 時，使絕緣纜線40退避或不退避均可。 更進一步，調整C〇2雷射之波長或強度且將同軸纜 之內部絕緣體14及絕緣纜線40之外被42更在靠近端 位置加以切斷，並將端部側之內部絕緣體14及外被 出而除去。依此，可將所有的纜線11，40 —起加工， 可有效地進行引線處理。 其後，在執行上述的引線處理之後，將外部導體13 ® 被42挾入於接地棒20, 30間而定位成預定之節距，並 接合構件24將接地棒20, 30及外部導體13及外被 定。接合構件24爲銲材之情況，以脈衝加熱等將接地彳 3〇加熱，使銲材熱熔融而固定。此外，在使用ACF或 以取代銲材之情況，加熱溫度比銲接更低，因此可使 造成對絕緣層之熱影響變少。 此外，上述實施形態中各種纜線之條數及配置係® 例，可適宜地變更。 此引 進行 1 1之 端部 自端 赛4〇。 1 1之 的位 。此 線11 部的 42拉 因此 及外 :使用 42固 W 20, i NCF :加熱 ί示一 -14- .200947473 尤其，只要同軸纜線11之外部導體13的部分之外徑與 絕緣纜線40之外徑大致同等的話，可在固定於接地棒20, 30之處處理成兩者在尺寸上等效，故配線的自由度爲高。 上述實施形態之纜線線束10，在兩端側附有連接器之情 況或僅一端側附有連接器而另一端側接續到基板之情況 等，可採用各種之形態。其次，將針對在纜線線束1 0之端 部安裝連接器之附有連接器之纜線線束進行說明。 第7圖顯示附有連接器之纜線線束的一端側之槪略俯視 〇 圖。又，第8圖係顯示第7圖中之箭號VII-VII位置的截面 圖。 如第7圖及第8圖所示，附有連接器之纜線線束50，係 纜線線束1

纜線11)的方式，外殼53安裝於連接器殼體51，此外殼53 係經由銲材或ACF而與接地棒30作電性接續。此外，外殼 53與接地棒30之接續，例如可藉由下面的方式進行：在面 向外殼53之接地棒30的處所之一部分預先設置開口部 53a ’在接地棒30之上覆以外殼53之後，從開口部53a導 入銲材或ACF而充塡於外殼53之下面與接地棒30之上面 200947473 之間（符號54之處）’以完成相互的導電接著。 如此構成的附有連接器之纜線線束50，當接續到插座 時，在外殼53之長度方向兩端附近接續到接地電路。當外 殼53接續到接地電路時’同軸纜線11之外部導體13因爲 接地棒20, 30經由外殼53而接地。 接續到接續端子52之前的纜線線束1〇,係將構成纜線線 束10的所有之纜線Π，4 0高精度地進行整列，同軸纜線 11之外部導體13及絕緣纜線40之外被42係被挾持於接地 〇 棒20，30上固定，因此使其配列不致於紊亂。是以，附有 連接器之纜線線束50各中心導體對各接續端子52係高精 度地定位者。又’如上述般，作爲絕緣纜線40之電源用纜 線之性能係爲良好。 將本發明相關之纜線線束10接續到FPC或PWB之接續 端子的構造亦屬可能。亦可經由FPC更接續到機器本體之 電路。 在本發明相關之纜線線束1

軸纜線11之外部導體13的部分之外徑更粗0.18mm，故可 -16- 200947473 容許絕緣纜線40之外徑至0.39mm。此時，絕緣纜線40之 中心導體41可容許至〇.33mm。將絕緣纜線40之外徑作成 與同軸纜線 11之外部導體同等，若外被 42之厚度爲 0.03mm，則絕緣纜線4 0之中心導體4 1的外徑可作成爲 0.15mm。雖然絕緣纜線40比同軸纜線11之外部導體的部 分之外徑更細，但是其差爲0.18 mm以內，故無多大關係。 (例2)同軸纜線1 1爲AWG46之情況 同軸纜線11之外部導體13的部分之外徑爲0.17mm左 〇 右，同軸纜線11之中心導體15的部分之外徑爲0.05mm左 右。 相對於此，絕緣纜線40宜爲AWG46或比AWG46更粗， 且其外被42宜爲0.03mm以上之厚度，因此絕緣纜線40之 外徑宜爲0.11mm以上。又，絕緣纜線40之外徑亦可比同 軸纜線11之外部導體13的部分之外徑更粗0.18mm，故可 容許絕緣纜線40之外徑至0.35 mm。此時，絕緣纜線40之 中心導體41的外徑可容許至0.2 9mm。將絕緣纜線40之外 © 徑作成與同軸纜線11之外部導體相同，且將外被42之厚 度作成0.03mm時，絕緣纜線40之中心導體41的外徑可作 成爲 0 · 11 mm。

[Embodiment] Hereinafter, an embodiment of a connection structure of a cable harness, a cable harness with a connector, and a cable harness according to the present invention will be described. FIG. 1 is a view showing a cable related to the present invention. Fig. 1(A) is a plan view of the cable harness, and Fig. 1(B) is an end view taken from the F direction of Fig. 1(A). Further, in the first (A) diagram, in order to simplify the drawing, the illustration of the second ground rod 30 to be described later is omitted. Further, Fig. 5 is an enlarged cross-sectional view of the vicinity of the arrow direction V of the first drawing. As shown in Fig. 1, the cable harness 10 has a plurality of coaxial cable Π, ' and at least one insulated cable 40, which are arranged in parallel. The coaxial cable 11 is used as a signal cable for signal transmission. In the present embodiment, 37 pieces are provided. As shown in FIG. 2, the coaxial cable 11 has a center conductor 15, an internal insulator 14 disposed on the outer circumference of the center conductor 15, an outer conductor 13 disposed on the outer circumference of the inner insulator 14, and an outer conductor 13 disposed on the outer conductor 13. The outer circumference of the insulation insulator 12 is configured to be coaxial. The coaxial cable 11 uses a cable equivalent to the AWG 44 according to, for example, the specifications of the AWG (American Wire Gauge). The coaxial cable 1 of the AWG 44 is a central conductor 15 formed of, for example, seven wires of a silver-plated copper alloy wire 15a having an outer diameter of 0.020 mm. Further, the internal insulator 14 is formed of a fluororesin such as PF A coated on the outer peripheral surface of the center conductor 15, and has a thickness of 0.04 mm formed by extrusion coating. Further, the outer conductor 13 is formed by winding a wire 13a of a copper alloy such as shovel on the outer peripheral surface of the inner insulator 14 and winding it into a spiral shape of 200947473 to form an outer diameter of 0.21 mm. In addition, the outer cover 12 is formed of a fluororesin such as PFA or the like which is coated on the outer peripheral surface of the outer conductor 13, and the outer diameter is 0.26 mm in the case of the AWG 44. The end portion of the coaxial cable 11 is subjected to lead processing, and the center conductor 15 , the internal insulator 14 and the outer conductor 13 are sequentially exposed to a predetermined length from the front end side. Further, the insulated cable 40 is provided in three in the present embodiment. As shown in Fig. 3, the insulating cable 40 has a center conductor 4 1 and an insulating outer cover 42 disposed on the outer periphery of the crucible 40, and is configured to be coaxial. The insulating cable 40, for example, the coaxial cable 11 is equivalent to the size of the AWG 44, and is a cable equivalent to the AWG 38 in the specification of the AWG. The center conductor 4 1 is, for example, a tin-plated copper alloy wire 4 1 . A total of seven strands are formed by twisting, and the outer layer 42 is formed of a fluororesin such as PFA or the like which is coated on the outer peripheral surface of the center conductor 41, and has an outer diameter of 〇.21 mm. The portion of the center conductor 41 has a diameter of 0.11 mm and the outer portion 42 has a thickness of 0.05 mm. The thickness of the outer cover 42 is thicker than the thickness of the inner insulator 14 of the coaxial cable 11 of the AWG 44. The insulated cable 40 is a cable used for power supply, and the cross-sectional area of the center conductor 41 is equal to or larger than the cross-sectional area of the center conductor 15 of the coaxial cable 11. Since the insulated cable 40 is configured by the center conductor 41 and the outer cover 42, it is easy to ensure that the cross-sectional area of the center conductor 41 is larger than that of the coaxial cable 11. When the outer portion of the insulating cable 40 is formed to have the same outer diameter as the layer of the outer conductor 13 of the coaxial cable 11, the outer conductor π of the coaxial cable 11 is preferably held by two ground rods 20, 30. And fixed. Further, 42 is sufficiently thick for the heat of fixing the-10-200947473 grounding bars 20, 30 to the coaxial cable U and the insulating cable 40, so that the outer cover 42 is melted without maintaining its insulating property. When the outer conductor 13 and the insulating cable 40 of the coaxial cable 11 are welded to the ground rods 20, 30 by pulse heating, the outer side of the insulating cable 40 is preferably made to have a thickness of 3 mm or more. When a low melting point solder material having a melting point of about 230 ° C is used, even if the insulating cable 40 having a thickness of 0.3 mm is welded to the ground rod 20, 30, the outer portion 42 is not melted and the insulating property can be maintained. Further, the end portion of the insulated cable 40 is also subjected to lead processing. On the end side in the longitudinal direction, the center conductor 41 is exposed to a predetermined length (e.g., the same length as the center conductor 15 of the coaxial cable 11). As shown in Fig. 1, the cable harness 10 is such that the outer conductor 13 and the outer sheath 42 are held on the ground rods 20, 30 by soldering, so that the center conductor 15 and the center conductor 41 are juxtaposed at a predetermined pitch, and the cable The position of the harness 1 〇 and the coaxial cable 1 1 can be fixed. The ground rods 20, 30 are plates that form the length of the outer conductive body 13 and the outer portion 42 of the insulated cable 40 covering all of the coaxial cables 11. For example, it is a conductive metal plate such as a copper plate. Further, as shown in Fig. 4, the opposing faces of the ground bars 20, 30 are fixed to the respective cables 11, 40 by the joint members 24 (see Fig. 5). For the joining member 24, for example, a plate welding material can be used, but an anisotropic conductive film (ACF), a non-conductive film (NCF), or the like can be used in addition to the plate welding material. By means of the joining members 24, the grounding bars 20, 30 are fixed to the outer conductors 13 of the coaxial cable 11 while being electrically connected. Further, even in the case where a non-conductive film is used on the joining members 24-11-200947473, as shown in Fig. 5, the joining member 24 is buried in the gap between the ground rods 20, 30 and the respective cables 11, 40. The way to move 'so the outer conductor 13 produces direct contact with the ground rods 20, 30' to achieve electrical conduction between the ground rods 20, 30 and the outer conductor 13. In this manner, each of the outer conductors 13 can be grounded together via the ground bars 20, 30. Further, although the joint member 24 is not fixed to the outer portion 42 of the insulated cable 40, the joint member 24 is moved and solidified by being embedded around the outer cover 42, thereby preventing the insulated cable 40 from being orthogonal to its axis. The direction of the direction of movement. That is, the insulated cable 40 is fixed to at least the axial direction by the ground bars 20, 30 and the joint member 24. Since the outer conductor 13 and the insulated cable 40 of the coaxial cable 11 are held by the ground bars 20 and 30, the cable 1 1 and 40 constituting all of the cable harnesses 10 can be accurately arranged. Arranged, and its arrangement is not confusing. Therefore, the connection of the connector terminals and the like of the terminal end portion of the cable harness 10 can be performed correctly. Further, since the cross-sectional area of the center conductor 41 of the insulated cable 40 is large and the insulation property is maintained well, the performance as the electric power source cable is good. In addition, although it is possible to use a form of a welding material for both the coaxial cable 11 and the insulated cable 40, a form of ACF or NCF for the insulated cable 40 for the coaxial cable 11, and a coaxial cable 1 for the insulated cable 40. Both the 1 and the insulated cable 40 are in the form of using ACF or NCF, but even if the joining member 24 (welding material) is thermally fused by any form of the welding material, the grounding rod 20, 30 times is used as long as the pulse is heated or the like. Just heat up. The difference between the outer diameter of the portion of the outer conductor -12-200947473 13 of the portion of the coaxial cable 挟-200947473 13 held by the ground rod 20, 30 and the outer diameter of the outer portion 42 of the insulated cable 40, when the coaxial cable 1 1 is AWG 42 Or a finer case than AWG42, at least to 0.18mm. When the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11 is 0.17 mm, the outer diameter of the insulated cable 40 is at least allowed to be 0.35 mm. If the ratio of the diameters of the two is taken, the outer diameter of the thicker portion is allowed to be at least about 2 times the outer diameter of the thinner portion. The insulated cable 40 is used as a power supply cable, so that the cross-sectional area of the center conductor 41 is preferably as large as possible (large diameter). As a result of the coarsening of the center conductor 41, the outer diameter of the insulated cable 40 may be larger than the outer diameter of the outer conductor 13 of the coaxial cable 11. As shown in Fig. 6, the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11 is allowed to be about 2 times larger than the outer diameter of the insulated cable 40. When the difference in outer diameter is 0.18 mm, the amount of the joint member 24 (welding material) can be adjusted, and the portion held by the ground rods 20, 30 can be buried by the joint member 24. Further, in the case where the insulating cable 40 is made thicker than the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11, the insulating cable 40 may be disposed on both sides of the coaxial cable 1 1 which is juxtaposed. Thereby, the coaxial cable 11 is disposed between the insulated cables 40 which are thicker than the coaxial cable 11. Next, a method of manufacturing the above-described cable harness 10 will be described. First, all of the cables 11, 40 constituting the cable harness 10 are arranged side by side and held by a jig or a belt or the like. The arrangement of the cables 11 and 40, for example, as shown in Fig. 1, is from the first core (the upper end position of Fig. 1) to the third core as the power supply insulated cable 40, from the fourth heart to The heart of the 40th (the lower end position of Fig. 1) serves as a signal coaxial cable 1 1. Further, the positions of the ends of all the cables 11, 40 are aligned. 200947473 Thereafter, all the ends of the cables 1, 1, 40 were subjected to lead processing. The line processing is performed by a laser processing machine such as a YAG laser or a C〇2 laser. First, the wavelength or intensity of the CCh laser is adjusted and the outer portion of the coaxial cable is counted from the end by a predetermined distance. Cut off and pull the side out to remove. In addition, when the C〇2 laser is emitted, the portion is preliminarily bent to be bent or the like to avoid the inhalation of the insulated cable, the wavelength or intensity of the YAG laser is adjusted, and the coaxial cable outer conductor 13 is removed. When the end portion © which is a predetermined length from the outer cut position is cut, and the outer conductor 13 on the end side is pulled out and removed, the insulated cable 40 may be retracted or not retracted. Further, the wavelength or intensity of the C〇2 laser is adjusted and the inner insulator 14 and the insulated cable 40 of the coaxial cable are cut off closer to the end position, and the inner insulator 14 on the end side is externally Was removed and removed. According to this, all the cables 11, 40 can be processed together, and the lead processing can be performed efficiently. Thereafter, after performing the above-described lead processing, the outer conductor 13 ® is inserted into the ground bars 20, 30 to be positioned at a predetermined pitch, and the bonding member 24 connects the ground bars 20, 30 and the outer conductor 13 and The outside is fixed. In the case where the joining member 24 is a welding material, the grounding crucible is heated by pulse heating or the like to thermally melt and fix the welding material. Further, in the case of using ACF or replacing the consumables, the heating temperature is lower than that of the soldering, so that the thermal influence on the insulating layer is reduced. Further, the number of the various cables and the arrangement of the various types of the cables in the above embodiment can be appropriately changed. This lead is performed at the end of the 1 1 self-end match. Bit 1 1 . The 42-pin pull of the 11th part of the line is therefore: 42 is used W 20, i NCF: heating is shown as a -14-.200947473, in particular, as long as the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11 and the insulated cable 40 When the outer diameters are substantially equal, they can be treated at the ground rods 20 and 30 to be equivalent in size, so that the degree of freedom of wiring is high. In the case of the cable harness 10 of the above-described embodiment, the connector may be attached to both end sides, or the connector may be attached to the one end side and the other end side may be connected to the substrate. Next, a cable harness with a connector attached to a connector at the end of the cable harness 10 will be described. Fig. 7 is a schematic plan view showing one end side of the cable harness with the connector attached. Further, Fig. 8 is a cross-sectional view showing the position of the arrow VII-VII in Fig. 7. As shown in FIGS. 7 and 8, the cable harness 50 with the connector, the center conductors 15 5, 4 1 at the ends of the cable harness 10 are individually connected to the connector housing. The connection terminal 51 of 51. The center conductors 15, 41 are connected to the splice terminal 52, for example, by soldering together by pulse heating. Further, in Fig. 7, the ground rod 30, the shape of the connector housing, and the illustration of the outer casing are omitted. ® As shown in Fig. 8, at the end of the cable harness 1 ,, the cables 11 and 40 placed on the connector housing 51 are covered (the coaxial cable 11 is illustrated in Fig. 8). The housing 53 is mounted to the connector housing 51, which is electrically connected to the ground rod 30 via a welding material or ACF. Further, the connection of the outer casing 53 to the ground rod 30 can be performed, for example, by providing an opening portion 53a in a portion facing the ground rod 30 of the outer casing 53 after the outer layer 53 is overlaid on the ground rod 30. A solder material or ACF is introduced from the opening portion 53a to be filled between the lower surface of the outer casing 53 and the upper surface 200947473 of the ground rod 30 (where the symbol 54) 'to complete the mutual conduction. The cable harness 50 with the connector thus constructed is connected to the ground circuit in the vicinity of both ends in the longitudinal direction of the casing 53 when it is connected to the socket. When the outer casing 53 is connected to the grounding circuit, the outer conductor 13 of the coaxial cable 11 is grounded via the outer casing 53 because of the ground bars 20, 30. The cable harness 1 接 before the connection terminal 52 is connected to all the cable turns constituting the cable harness 10, and the outer conductor 13 and the insulated cable 40 of the coaxial cable 11 are arranged in a high precision. The 42 series is held on the grounding pry bars 20, 30, so that the arrangement is not disturbed. Therefore, each of the center conductors of the cable harness 50 with the connector is positioned with high precision for each of the connection terminals 52. Further, as described above, the performance of the power cable for the insulated cable 40 is good. It is also possible to connect the cable harness 10 of the present invention to the connection terminal of the FPC or PWB. It can also be connected to the circuit of the machine body via FPC. In the cable harness 10 of the present invention, an example of the size of each cable is shown. ® (Example 1) When the coaxial cable 1 1 is the AWG 44 The outer diameter of the portion of the outer conductor 13 of the coaxial cable 11 is about 0.21 mm, and the outer diameter of the portion of the center conductor 15 of the coaxial cable 11 is about 0.06 mm. On the other hand, the insulating cable 40 is preferably AWG44 or thicker than the AWG44, and the outer portion 42 is preferably 0.03 mm or more. Therefore, the outer diameter of the insulating cable 40 is preferably 0.12 mm or more. Further, the outer diameter of the insulated cable 40 can also be 0.18 mm thicker than the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11, so that the outer diameter of the insulated cable 40 can be allowed to be -16-2009. At this time, the center conductor 41 of the insulated cable 40 can be tolerated to 〇.33 mm. The outer diameter of the insulated cable 40 is made equal to the outer conductor of the coaxial cable 11. If the thickness of the outer cover 42 is 0.03 mm, the outer diameter of the center conductor 4 1 of the insulated cable 40 can be made 0.15 mm. Although the insulated cable 40 is thinner than the outer diameter of the outer conductor portion of the coaxial cable 11, the difference is not more than 0.18 mm, so it does not matter much. (Example 2) When the coaxial cable 1 1 is the AWG 46, the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11 is 0.17 mm left and right, and the outer diameter of the portion of the center conductor 15 of the coaxial cable 11 is about 0.05 mm. . On the other hand, the insulating cable 40 is preferably AWG46 or thicker than the AWG 46, and the outer sheath 42 is preferably 0.03 mm or more. Therefore, the outer diameter of the insulating cable 40 is preferably 0.11 mm or more. Further, the outer diameter of the insulated cable 40 can be made thicker than the outer diameter of the portion of the outer conductor 13 of the coaxial cable 11 by 0.18 mm, so that the outer diameter of the insulated cable 40 can be allowed to be 0.35 mm. At this time, the outer diameter of the center conductor 41 of the insulated cable 40 can be tolerated to 0.29 mm. When the outer diameter of the insulated cable 40 is the same as the outer conductor of the coaxial cable 11, and the thickness of the outer cover 42 is made 0.03 mm, the outer diameter of the center conductor 41 of the insulated cable 40 can be made 0. 11 mm. . Although the description has been given of an example in which the cables are held in a row for the common ground rods, it is also possible to divide the end portions of one cable harness into two or more and to be held together in common. The ground rods are arranged in two rows in a horizontal or vertical direction. Further, in addition to the end portions, the respective cables may be wound by a tape and bundled. The present invention has been described with reference to the detailed and specific embodiments thereof, and it is obvious to those skilled in the art that various changes or modifications can be made without departing from the spirit and scope of the invention.
