先前，已知有使平角導體以規定間隔並排、且夾著平角導體而黏合絕緣膜的扁平電纜。該扁平電纜係於末端露出平角導體，且與外部設備電性連接。作為扁平電纜之一例，已知有如下類型：將以規定間隔設有孔部之絕緣膜黏合於平角導體，藉由在孔部切開，而於端部露出平角導體。例如，專利文獻1中，揭示有如下扁平電纜：使一根或複數根極細同軸電線與複數根平角導體混合存在，且使其等以固定相隔距離而並排地配置於2塊絕緣膜間。 Conventionally, a flat cable in which a rectangular conductor is arranged at a predetermined interval and a flat-angle conductor is sandwiched to bond an insulating film is known.

[專利文獻1]日本特許第3620821號 [Patent Document 1] Japanese Patent No. 3620821
專利文獻1中，極細同軸電線與平角導體以固定距離而並排，但因各線之用途不同，故而若使兩者以同等方式並排，則當將該扁平電纜連接於基板等連接對象時，操作性變差。 In the case of the patent document 1, the ultrafine coaxial electric wire and the rectangular conductor are arranged side by side at a fixed distance. However, since the use of the respective lines is different, if the two are connected in parallel in the same manner, the operability is obtained when the flat cable is connected to a connection object such as a substrate. Getting worse.
因此，本發明之目的在於提供一種同軸電線與平角導體混合 存在的單一的扁平電纜，其末端部之操作性優良。 Accordingly, it is an object of the present invention to provide a coaxial wire that is mixed with a flat angle conductor. The single flat cable that is present has excellent operability at the end portion.
為了達成上述目的，本發明之扁平電纜具備：複數根平角導體，其呈平面狀排列；複數根同軸電線，其呈平面狀排列；一對絕緣膜，其自排列面之兩側夾入上述複數根平角導體及上述複數根同軸電線；及接著層，其將一對上述絕緣膜彼此接著；且連接構件連接於在上述複數根平角導體及上述複數根同軸電線之長度方向上的兩端部露出的上述複數根平角導體及上述複數根同軸電線，上述複數根平角導體之並排間距與上述複數根同軸電線之並排間距不同。 In order to achieve the above object, the flat cable of the present invention comprises: a plurality of flat-angle conductors arranged in a planar shape; a plurality of coaxial wires arranged in a planar shape; and a pair of insulating films sandwiching the plurality of the self-aligned faces a root angle conductor and the plurality of coaxial wires; and an adhesive layer connecting the pair of insulating films to each other; and the connecting member is connected to both end portions of the plurality of flat-angle conductors and the plurality of coaxial wires in a longitudinal direction thereof And the plurality of flat-angle conductors and the plurality of coaxial wires, wherein a side-by-side spacing of the plurality of rectangular conductors is different from a side-by-side spacing of the plurality of coaxial wires.

首先，列出本申請發明之實施形態的內容進行說明。 First, the contents of the embodiments of the present invention will be described.
作為本申請發明之實施形態之扁平電纜， a flat cable as an embodiment of the invention of the present application,
(1)具備：複數根平角導體，其呈平面狀排列；複數根同軸電線，其呈平面狀排列；一對絕緣膜，其自排列面之兩側夾入上述複數根平角導體及上述複數根同軸電線；及接著層，其將一對上述絕緣膜彼此接著；連接構件連接於在上述複數根平角導體及上述複數根同軸電線之長度方向上的兩端部露出的上述複數根平角導體及上述複數根同軸電線，上述複數根平角導體之並排間距與上述複數根同軸電線之並排間距不同。 (1) having: a plurality of flat-angle conductors arranged in a planar shape; a plurality of coaxial wires arranged in a planar shape; and a pair of insulating films sandwiching the plurality of flat-angle conductors and the plurality of roots on both sides of the self-aligning surface a coaxial wire; and an adhesive layer, wherein the pair of insulating films are connected to each other; and the connecting member is connected to the plurality of rectangular conductors exposed at both end portions of the plurality of rectangular conductors and the plurality of coaxial wires in the longitudinal direction The plurality of coaxial wires have a side-by-side spacing of the plurality of flat-angle conductors different from the side-by-side spacing of the plurality of coaxial wires.
訊號傳輸用同軸電線與供電用平角導體設於一個扁平電纜中，故而，能由單一的扁平電纜來實現訊號傳輸與供電。故而，電纜之操作性提高，從而能有效率地進行配線作業。又，平角導體之並排間距與同軸電線之並排間距不同，故而，關於直徑不同的平角導體與同軸電線之並排間距，可分別單獨地設定為適於利用絕緣膜進行層壓之並排間距、且適於與連接構件連接之並排間距。 The coaxial cable for signal transmission and the flat-angle conductor for power supply are arranged in a flat cable, so that signal transmission and power supply can be realized by a single flat cable. Therefore, the operability of the cable is improved, so that the wiring work can be performed efficiently. Moreover, the side-by-side spacing of the rectangular conductors is different from the side-by-side spacing of the coaxial wires. Therefore, the side-by-side spacing of the rectangular conductors and the coaxial wires having different diameters can be individually set to be parallel spacing suitable for lamination using an insulating film, and The side-by-side spacing is connected to the connecting member.
(2)較佳為，上述同軸電線與上述平角導體被分為不同的群，且上述連接構件分別連接於各個群。 (2) Preferably, the coaxial electric wire and the rectangular conductor are divided into different groups, and the connecting members are respectively connected to the respective groups.
藉此，易於分別對同軸電線與平角導體進行末端處理。 Thereby, it is easy to perform end treatment on the coaxial wire and the rectangular conductor separately.
(3)較佳為，上述平角導體之上述並排間距大於上述同軸電線之上述並排間距。 (3) Preferably, the side-by-side spacing of the above-mentioned rectangular conductors is greater than the above-mentioned side-by-side spacing of the coaxial wires.
若平角導體之並排間距大於同軸電線之並排間距，則能使平角導體之寬度大於同軸電線之直徑，適於使平角導體中流動相對較大的電流。 If the side-by-side spacing of the flat-angle conductors is greater than the side-by-side spacing of the coaxial wires, the width of the flat-angle conductor can be made larger than the diameter of the coaxial wires, and is suitable for flowing a relatively large current in the rectangular conductor.
(4)較佳為，上述連接構件包含第1連接構件與第2連接構件，於由上述複數根平角導體構成之第1群與由上述複數根同軸電線構成之第2群之間的上述絕緣膜上設有縫隙，上述第1連接構件連接於上述第1群之端部，上述第2連接構件連接於上述第2群之端部。 (4) Preferably, the connecting member includes the first connecting member and the second connecting member, and the insulating layer between the first group of the plurality of rectangular conductors and the second group of the plurality of coaxial wires A slit is formed in the film, the first connecting member is connected to an end portion of the first group, and the second connecting member is connected to an end portion of the second group.
利用縫隙將第1群與第2群分開，藉此，當第1群與第2群之連接端不同等時，亦能容易地進行連接作業。 By separating the first group from the second group by the slit, the connection work can be easily performed when the connection ends of the first group and the second group are different.
以下，參照圖式，對於本發明之扁平電纜之實施形態的示例進行說明。 Hereinafter, an example of an embodiment of the flat cable of the present invention will be described with reference to the drawings.
圖1係本實施形態之扁平電纜10之端部的俯視圖，圖2係扁平電纜10之剖面圖。 1 is a plan view of an end portion of a flat cable 10 of the present embodiment, and FIG. 2 is a cross-sectional view of the flat cable 10.
本實施形態之扁平電纜10係用於將一對外部設備電性連接，或者用於進行設備內配線之電纜。如圖1所示，扁平電纜10具備：呈平面狀排列之複數根平角導體11、呈平面狀排列之複數根同軸電線12、及覆蓋該複數根平角導體11與複數根同軸電線12之絕緣膜13。複數根平角導體11與複數根同軸電線12係彼此平行地排列。 The flat cable 10 of the present embodiment is used for electrically connecting a pair of external devices or a cable for wiring inside the device. As shown in FIG. 1, the flat cable 10 includes a plurality of rectangular conductors 11 arranged in a planar shape, a plurality of coaxial wires 12 arranged in a planar shape, and an insulating film covering the plurality of rectangular conductors 11 and the plurality of coaxial wires 12. 13. The plurality of rectangular conductors 11 and the plurality of coaxial wires 12 are arranged in parallel with each other.
平角導體11係剖面大致扁平的矩形狀的鍍錫銅導體。複數根平角導體11以規定的並排間距P1呈平面狀排列。複數根平角導體11之並排間距P1例如為6.25mm。當將平角導體11用作供電線時，較佳為使其寬度加寬。若加寬平角導體11之寬度，則其並排間距P1亦增大。本實施形態之扁平電纜10中，較佳為，使平角導體11之並排間距P1大於同軸電線12之並排間距P2。 The rectangular conductor 11 is a rectangular tinned copper conductor having a substantially flat cross section. The plurality of flat-angle conductors 11 are arranged in a planar shape at a predetermined parallel pitch P1. The side-by-side pitch P1 of the plurality of rectangular conductors 11 is, for example, 6.25 mm. When the rectangular conductor 11 is used as a power supply line, it is preferable to widen its width. If the width of the rectangular conductor 11 is widened, the side-by-side spacing P1 also increases. In the flat cable 10 of the present embodiment, it is preferable that the side-by-side pitch P1 of the rectangular conductors 11 is larger than the side-by-side pitch P2 of the coaxial electric wires 12.
同軸電線12例如為自中心起呈同心圓狀依序積層有中心導體、絕緣體、外部導體及外被的電線。複數根同軸電線12係以規定的並排間距P2呈平面狀排列。複數根同軸電線12之並排間距P2例如為0.5mm。當將同軸電線12用於訊號之高速傳輸用途時，同軸電線12之中心導體之剖面積無需較大，多使用外徑為0.5mm或更細的同軸電線。此時，自縮小配線空間方面而言，較佳為，縮緊各同軸電線12之間隔而儘量成為密度高的集合狀態。 The coaxial electric wire 12 is, for example, an electric wire in which a center conductor, an insulator, an outer conductor, and an outer sheath are laminated in a concentric manner from the center. The plurality of coaxial wires 12 are arranged in a planar shape at a predetermined parallel pitch P2. The side-by-side spacing P2 of the plurality of coaxial wires 12 is, for example, 0.5 mm. When the coaxial electric wire 12 is used for high-speed transmission of signals, the cross-sectional area of the center conductor of the coaxial electric wire 12 need not be large, and a coaxial electric wire having an outer diameter of 0.5 mm or less is often used. At this time, in terms of reducing the wiring space, it is preferable to tighten the interval between the coaxial wires 12 and to make the density as high as possible.
又，可根據目的而以混合存在有供電用寬幅平角導體、通常訊號用平角導體、高速傳輸用同軸電線該等三者之形狀來製作扁平電纜10，且僅使各個末端形成分支而進行連接。藉此，無需分別對各線進行配線，能實現省配線、降低成本。 In addition, the flat cable 10 can be formed in a shape in which three types of wide angled conductors for power supply, flat angle conductors for normal signals, and coaxial wires for high-speed transmission are mixed in accordance with the purpose, and only the respective ends are branched and connected. . Thereby, it is not necessary to separately wire each line, and it is possible to save wiring and reduce cost.
絕緣膜13係由聚酯樹脂等形成。於絕緣膜13，在彼此對向之面上，分別設有由熱塑性樹脂、熱硬化性樹脂或紫外線硬化性樹脂等構成的接著層14。 The insulating film 13 is formed of a polyester resin or the like. The insulating film 13 is provided with an adhesive layer 14 made of a thermoplastic resin, a thermosetting resin, or an ultraviolet curable resin, respectively, on the surfaces facing each other.
一對絕緣膜13係以自排列面之兩側夾入呈平面狀排列的平角導體11及呈平面狀排列的同軸電線12的狀態，透過接著層14而彼此黏 合。藉此，平角導體11及同軸電線12被一對絕緣膜13覆蓋。此外，較佳為，接著層14與絕緣膜13之接著力設定為強於其與平角導體11及同軸電線12之接著力。例如，較佳為，使用如下接著劑，其與構成絕緣膜13之樹脂的接著力係強於與構成平角導體11之金屬的接著力、或與構成同軸電線12之外周之外被的接著力。 The pair of insulating films 13 are in a state in which the flat-angle conductors 11 arranged in a plane and the coaxial wires 12 arranged in a plane are sandwiched between the two sides of the self-aligned surface, and are adhered to each other through the adhesive layer 14 Hehe. Thereby, the rectangular conductor 11 and the coaxial electric wire 12 are covered by the pair of insulating films 13. Further, it is preferable that the adhesion force of the bonding layer 14 and the insulating film 13 is set to be stronger than the bonding force with the rectangular conductor 11 and the coaxial electric wire 12. For example, it is preferable to use an adhesive which is stronger than the bonding force of the resin constituting the insulating film 13 to the bonding force with the metal constituting the rectangular conductor 11, or the bonding force outside the outer circumference of the coaxial electric wire 12. .
於扁平電纜10之長度方向上的兩端部，絕緣膜13被除去規定長度，平角導體11及同軸電線12露出。所露出的平角導體11及同軸電線12分別連接於連接構件C1、C2。作為連接構件C1、C2，可使用連接器、基板、可撓性印刷基板(FPC)、印刷終端等。平角導體11及同軸電線12經由該連接構件C1、C2而與外部設備等連接。此外，亦能藉由在絕緣膜13被除去而露出之平角導體11及同軸電線12之一面黏附增強膜，而使平角導體11及同軸電線12在維持並排形狀的情況下連接於構件C1、C2。 At both end portions in the longitudinal direction of the flat cable 10, the insulating film 13 is removed by a predetermined length, and the rectangular conductor 11 and the coaxial electric wire 12 are exposed. The exposed rectangular conductor 11 and the coaxial electric wire 12 are connected to the connecting members C1 and C2, respectively. As the connecting members C1 and C2, a connector, a substrate, a flexible printed circuit board (FPC), a printing terminal, or the like can be used. The rectangular conductor 11 and the coaxial electric wire 12 are connected to an external device or the like via the connection members C1 and C2. Further, the reinforcing film can be adhered to one surface of the rectangular conductor 11 and the coaxial electric wire 12 exposed by the removal of the insulating film 13, so that the rectangular conductor 11 and the coaxial electric wire 12 are connected to the members C1 and C2 while maintaining the side-by-side shape. .
較佳為，於平角導體11與同軸電線12之露出部分，將其等分為不同的群。此時，於自露出部分起向前端之部分，可僅將平角導體11匯總而作為第1群A，僅將同軸電線12匯總而作為第2群B，分別進行末端處理而進行操作。具體而言，連接構件C1(例如，連接器或FPC)連接於第1群A(平角導體11)，且連接構件C2(例如，連接器)連接於第2群B(同軸電線12)。 Preferably, the exposed portion of the rectangular conductor 11 and the coaxial electric wire 12 is equally divided into different groups. At this time, in the portion from the exposed portion to the front end, only the rectangular conductors 11 are collectively used as the first group A, and only the coaxial electric wires 12 are collectively collected as the second group B, and the end processing is performed and operated. Specifically, the connection member C1 (for example, a connector or FPC) is connected to the first group A (the rectangular conductor 11), and the connection member C2 (for example, the connector) is connected to the second group B (the coaxial wire 12).
此外，亦可藉由將絕緣膜黏貼於平角導體11露出之部分等，而使各平角導體11不會短路。同軸電線12之外周被外被覆蓋，故而，於同軸電線12露出之部分，無需防止各同軸電線12的短路，而亦可將樹脂膜黏貼於同軸電線12，以使連接構件C2附近維持並排狀態。 Further, the flat-angle conductors 11 can be prevented from being short-circuited by adhering the insulating film to the exposed portion of the rectangular conductor 11. Since the outer circumference of the coaxial electric wire 12 is covered, the portion of the coaxial electric wire 12 that is exposed does not need to be prevented from being short-circuited by the coaxial electric wires 12, and the resin film may be adhered to the coaxial electric wire 12 so that the vicinity of the connecting member C2 is maintained side by side. .
繼而，使用圖3及圖4對本實施形態之扁平電纜10之製造方法進行說明。 Next, a method of manufacturing the flat cable 10 of the present embodiment will be described with reference to FIGS. 3 and 4.
就本實施形態之扁平電纜10而言，首先作成長扁平電纜15，接著，將長扁平電纜15切斷成所需長度而作成短扁平電纜，進而藉由對短扁平電纜進行加工而作成扁平電纜10。 In the flat cable 10 of the present embodiment, the flat cable 15 is first grown, and then the long flat cable 15 is cut into a desired length to form a short flat cable, and the flat cable is processed by processing the short flat cable. 10.
首先，如圖3所示，作成長扁平電纜15。首先，於彼此對向地彼此擠壓之一對層壓輥21、21之間，以規定的間隔並排地供給複數根平角導體11及複數根同軸電線12。如上所述，以複數根平角導體11之並排間距P1與複數根同軸電線12之並排間距P2不同的方式並排。繼而，於一對層壓輥21、21之間，自一對絕緣膜保持輥23、23，將塗布有接著層14之絕緣膜13、13供給至平角導體11及同軸電線12之排列面之兩側。而且，利用一對層壓輥21、21，對夾入有平角導體11及同軸電線12之一對絕緣膜13、13進行擠壓，將絕緣膜13、13彼此黏合，形成長扁平電纜15。如此形成之長扁平電纜15自層壓輥21、21被搬送至下游，進而由捲取輥22捲取。 First, as shown in FIG. 3, the flat cable 15 is grown. First, a plurality of flat-angle conductors 11 and a plurality of coaxial electric wires 12 are supplied side by side at a predetermined interval between one pair of laminating rolls 21 and 21 which are pressed against each other. As described above, the side-by-side pitch P1 of the plurality of rectangular conductors 11 is arranged side by side in a manner different from the side-by-side pitch P2 of the plurality of coaxial wires 12. Then, between the pair of laminating rolls 21 and 21, the insulating films 13 and 13 coated with the adhesive layer 14 are supplied from the pair of insulating film holding rolls 23 and 23 to the arrangement faces of the rectangular conductor 11 and the coaxial electric wire 12. On both sides. Then, the insulating films 13 and 13 are pressed against one of the flat-angle conductors 11 and the coaxial electric wires 12 by the pair of laminating rolls 21 and 21, and the insulating films 13 and 13 are bonded to each other to form the long flat cable 15. The long flat cable 15 thus formed is conveyed to the downstream from the laminating rolls 21, 21, and further taken up by the take-up roll 22.
繼而，切斷長扁平電纜15，獲得所需長度的短扁平電纜。而且，如圖4所示，於短扁平電纜之端部，在絕緣膜13上形成切口後除去絕緣膜13，使平角導體11及同軸電線12露出。藉此，獲得扁平電纜10。此外，平角導體11及同軸電線12分別連接於連接構件C1、C2。 Then, the long flat cable 15 is cut to obtain a short flat cable of a desired length. Further, as shown in FIG. 4, a slit is formed in the insulating film 13 at the end portion of the short flat cable, and the insulating film 13 is removed to expose the rectangular conductor 11 and the coaxial electric wire 12. Thereby, the flat cable 10 is obtained. Further, the rectangular conductor 11 and the coaxial electric wire 12 are connected to the connecting members C1 and C2, respectively.
近年來，為了達成高速訊號傳輸，需要屏蔽效應高的配線材，為了對應於此種高速訊號傳輸，適宜使用同軸電線12。又，另一方面，亦需要由一個扁平電纜來實現訊號傳輸與供電，自該供電目的考慮，平角 導體11優於同軸電線12。 In recent years, in order to achieve high-speed signal transmission, a wiring material having a high shielding effect is required, and in order to correspond to such high-speed signal transmission, the coaxial electric wire 12 is suitably used. On the other hand, it is also necessary to realize signal transmission and power supply by a flat cable. For the purpose of the power supply, the flat angle is also considered. The conductor 11 is superior to the coaxial wire 12.
根據本實施形態之扁平電纜10，使同軸電線12與平角導體11混合存在於一個扁平電纜10中而設置，故而能由單一的扁平電纜10來實現將同軸電線12用於高速訊號傳輸、將平角導體11用於供電。故而，能提高扁平電纜10之操作性，實現有效率的配線作業。 According to the flat cable 10 of the present embodiment, the coaxial electric wire 12 and the rectangular conductor 11 are mixed and disposed in one flat cable 10, so that the coaxial cable 12 can be used for high-speed signal transmission and the flat angle can be realized by the single flat cable 10. The conductor 11 is used for power supply. Therefore, the operability of the flat cable 10 can be improved, and efficient wiring work can be realized.
又，根據本實施形態之扁平電纜10，複數根平角導體11之並排間距P1與複數根同軸電線12之並排間距P2不同。於平角導體11與同軸電線12，可根據各自的用途而設定直徑。故而，如圖2所示，當與排列面正交地俯視時，平角導體11與同軸電線12之寬度不同。因此，須以平角導體11之並排間距P1與同軸電線12之並排間距P2成為適於利用絕緣膜13進行層壓之並排間距、且適於與連接構件C1、C2連接之並排間距的方式，分別設定為不同的間距。本實施形態之扁平電纜10則符合該要求。 Further, according to the flat cable 10 of the present embodiment, the side-by-side pitch P1 of the plurality of rectangular conductors 11 is different from the side-by-side pitch P2 of the plurality of coaxial wires 12. The diameter of the rectangular conductor 11 and the coaxial electric wire 12 can be set according to the respective applications. Therefore, as shown in FIG. 2, the planer conductor 11 and the coaxial electric wire 12 have different widths when viewed in plan from the plane orthogonal to the arrangement surface. Therefore, the side-by-side pitch P1 of the rectangular conductors 11 and the side-by-side pitch P2 of the coaxial electric wires 12 must be a side-by-side spacing suitable for lamination by the insulating film 13, and a side-by-side spacing suitable for connection with the connecting members C1 and C2, respectively Set to a different pitch. The flat cable 10 of the present embodiment meets this requirement.
又，根據本實施形態，平角導體11與同軸電線12被分為不同的群A、B，且將連接構件C1、C2連接於各個群A、B，故而，容易分別對平角導體11與同軸電線12進行末端處理。 Further, according to the present embodiment, the rectangular conductor 11 and the coaxial electric wire 12 are divided into different groups A and B, and the connecting members C1 and C2 are connected to the respective groups A and B. Therefore, it is easy to respectively separate the rectangular conductor 11 and the coaxial electric wire. 12 end treatment.
又，根據本實施形態，平角導體11之並排間距P1大於同軸電線12之並排間距P2，故而，能使平角導體11之寬度大於同軸電線12之直徑，適於使平角導體11中流動相對較大的電流。 Further, according to the present embodiment, the side-by-side pitch P1 of the rectangular conductors 11 is larger than the side-by-side pitch P2 of the coaxial electric wires 12, so that the width of the rectangular conductors 11 can be made larger than the diameter of the coaxial electric wires 12, and it is suitable for relatively large flow in the rectangular conductor 11. Current.
以上，已參照特定的實施態樣對本發明進行了詳細說明，但業者可知，可在不脫離本發明之精神與範圍的情況下進行各種變更或修正。又，上文所說明之構成構件的數量、位置、形狀等並不限於上述實施形態，當實施本發明時，可變更為適宜的數量、位置、形狀等。 The present invention has been described in detail above with reference to the specific embodiments thereof. It is understood that various changes and modifications may be made without departing from the spirit and scope of the invention. Further, the number, position, shape, and the like of the constituent members described above are not limited to the above-described embodiments, and when the present invention is implemented, a more appropriate number, position, shape, and the like can be changed.
例如，平角導體11並不限於供電用途，亦可用作訊號線。另一方面，同軸電線12尤其適於重視屏蔽特性之訊號傳輸，但亦可用於供電用途。 For example, the rectangular conductor 11 is not limited to power supply use, and can also be used as a signal line. On the other hand, the coaxial wire 12 is particularly suitable for signal transmission with a focus on shielding characteristics, but can also be used for power supply purposes.
例如，多數情況下，由平角導體11構成之第1群A與由同軸電線12構成之第2群B分別連接於不同連接構件C1、C2(參照圖1)。此時，亦可如圖5所示之扁平電纜100般，於第1群A與第2群B之間的絕緣膜13上設有縫隙S。於縫隙S之末端部，設有與縫隙S正交的短縫隙S1，且以縫隙S不會進一步由此向內側擴展的方式進行處理。根據該構成，當第1群A與第2群B之連接端不同時，由縫隙S將第1群A與第2群B分開，藉此，可容易地進行連接作業。 For example, in many cases, the first group A composed of the rectangular conductors 11 and the second group B composed of the coaxial electric wires 12 are connected to the different connection members C1 and C2 (see FIG. 1). At this time, as in the flat cable 100 shown in FIG. 5, a slit S may be provided in the insulating film 13 between the first group A and the second group B. A short slit S1 orthogonal to the slit S is provided at the end portion of the slit S, and the slit S is processed so as not to expand further inward. According to this configuration, when the connection ends of the first group A and the second group B are different, the first group A and the second group B are separated by the slit S, whereby the connection work can be easily performed.
此外，可代替短縫隙S1，而藉由在絕緣膜13上的縫隙S之末端部的部分形成圓孔、或將膠帶黏貼於該部分等，來抑制縫隙S之擴展。又，縫隙S可設於扁平電纜100之長度方向上的兩端部，亦可僅設於一端部。 Further, instead of the short slit S1, the expansion of the slit S can be suppressed by forming a circular hole in the portion of the end portion of the slit S on the insulating film 13, or adhering the tape to the portion or the like. Further, the slit S may be provided at both end portions in the longitudinal direction of the flat cable 100, or may be provided only at one end portion.
