作為用以連接機器間或機器內的纜線，眾所周知有於平衡傳送用平坦狀纜線構件的端部具有連接器部的構造(例如，參照專利文獻1)，此纜線構件是成對的信號傳路路徑與接地部交互並列而能平衡傳送的構造，且，係成對之信號端子部與接地端子部露出於端部的構造。連接器部安裝於該平衡傳送用平坦狀纜線構件的端部，而將該平衡傳送用平坦狀纜線構件的信號端子部本身與接地端子部本身設為端子部。As a cable for connecting the machine room or the inside of the machine, it is known that the end portion of the flat cable member for balanced transfer has a connector portion (for example, refer to Patent Document 1), and the cable members are paired. The signal transmission path and the ground portion are alternately arranged to balance the transmission structure, and the signal terminal portion and the ground terminal portion are exposed to the end portion. The connector portion is attached to the end portion of the balanced transmission flat cable member, and the signal terminal portion itself of the balanced transmission flat cable member and the ground terminal portion itself are referred to as terminal portions.
又，也有使極細的複數條同軸纜線集合一體化的線束形狀者，此種纜線中，有複數條同軸纜線與絕緣纜線並列配置，且前述複數條同軸纜線的外部導體及前述絕緣纜線之中心導體導電接著於共用的接地條者(例如，參照專利文獻2)Further, in the case of a wire harness shape in which a plurality of extremely small coaxial cables are integrated, a plurality of coaxial cables are arranged in parallel with the insulated cable, and the outer conductors of the plurality of coaxial cables and the aforementioned The center conductor of the insulated cable is electrically connected to the common grounding strip (for example, refer to Patent Document 2)

謀求電子機器的小型化及輕量化且進一步的高性能，藉此，處理的資訊量也會增大。所以，將複數條同軸纜線設成線束形狀並透過中間基板連接於機器的基板時，乃期望進一步改善線束之末端的傳送特性或雜訊特性等電性特性。In order to reduce the size and weight of electronic equipment and further improve the performance, the amount of information to be processed also increases. Therefore, when a plurality of coaxial cables are formed in a harness shape and connected to the substrate of the machine through the intermediate substrate, it is desirable to further improve the electrical characteristics such as the transmission characteristics or the noise characteristics at the ends of the wire harness.
在此，本發明的目的在於提供一種確保良好的電性特性且高密度安裝的同軸纜線線束。Here, it is an object of the present invention to provide a coaxial cable harness that ensures good electrical characteristics and is mounted at a high density.
關於能解決上述課題之本發明的同軸纜線線束，係具備複數條同軸纜線及中間基板的同軸纜線線束，該複數條同軸纜線具有中心導體、配設於前述中心導體外周的內部絕緣體、配設於前述內部絕緣體外周的外部導體、及配設於前述外部導體外周的外覆層，該中間基板連接前述複數條同軸纜線之至少一端側，該同軸纜線線束的特徵在於：前述中間基板配列有複數個信號線部及複數個接地線部；在連接於前述同軸纜線側的相反側的一端，前述信號線部及前述接地線部以等間隔P配列；在連接於前述同軸纜線側之一端的前述信號線部及前述接地線部的間隔係與在另一端的前述等間隔P不同；將前述信號線部之數量設為m，前述接地線部之數量設為n，前述同軸纜線之數量設為c時，則「m≦c＜m+n」；前述信號線部分別連接於一條前述同軸纜線的中心導體；前述接地線部之全部或至少一者未連接於前述中心導體而是連接於全部或至少一者前述外部導體；連接於前述信號線部的前述同軸纜線中至少一者的直徑大於前述間隔P大。A coaxial cable harness according to the present invention which can solve the above problems is a coaxial cable harness including a plurality of coaxial cables and an intermediate substrate, the plurality of coaxial cables having a center conductor and an internal insulator disposed on an outer circumference of the center conductor And an outer conductor disposed on an outer circumference of the inner insulating body and an outer layer disposed on an outer circumference of the outer conductor, wherein the intermediate substrate is connected to at least one end side of the plurality of coaxial cables, wherein the coaxial cable harness is characterized by: The intermediate substrate is provided with a plurality of signal line portions and a plurality of grounding wire portions; and at one end opposite to the side of the coaxial cable, the signal line portion and the grounding wire portion are arranged at equal intervals P; and are connected to the coaxial line The interval between the signal line portion and the ground line portion at one end of the cable side is different from the equal interval P at the other end; the number of the signal line portions is m, and the number of the ground line portions is n, When the number of the coaxial cables is c, "m≦c<m+n"; the signal line portions are respectively connected to the center conductors of one of the coaxial cables; All or at least one of the ground portions is not connected to the center conductor but is connected to all or at least one of the outer conductors; at least one of the coaxial cables connected to the signal line portion has a larger diameter than the interval P .
本發明的同軸纜線線束，其中較佳為至少一個前述信號線部或前述接地線部的兩端部係以在前述中間基板之寬度方向上成為不同位置的方式彎曲。In the coaxial cable harness of the present invention, it is preferable that at least one of the signal line portions or both end portions of the ground line portion is curved so as to have different positions in the width direction of the intermediate substrate.
又，本發明的同軸纜線線束，其中以與前述已彎曲之信號線部鄰接的接地線部係配合前述已彎曲之信號線部的彎曲來變更寬度尺寸為佳。Moreover, in the coaxial cable harness of the present invention, it is preferable to change the width dimension by fitting the curved portion of the bent signal line portion to the ground line portion adjacent to the bent signal line portion.
又，本發明的同軸纜線線束，其中較佳為前述同軸纜線的前述信號線部及前述接地線部之一端部係均等配列，前述同軸纜線之中心導體連接於前述信號線部，前述同軸纜線之外部導體或中心導體連接於前述接地線部之另一端，前述同軸纜線之配列間距係均等，且前述同軸纜線的配列間距比前述信號線部及前述接地線部的配列間距還大。Further, in the coaxial cable harness of the present invention, preferably, the signal line portion of the coaxial cable and one end portion of the ground line portion are evenly arranged, and a center conductor of the coaxial cable is connected to the signal line portion. The outer conductor or the center conductor of the coaxial cable is connected to the other end of the grounding line portion, the arrangement pitch of the coaxial cable is equal, and the arrangement pitch of the coaxial cable is smaller than the arrangement pitch of the signal line portion and the ground line portion. Still big.
又，本發明的同軸纜線線束，其中較佳為複數個前述接地線部連結，此連結部分成為與前述同軸纜線之外部導體連接的連接部。Further, in the coaxial cable harness of the present invention, preferably, the plurality of grounding wire portions are connected, and the connecting portion is a connecting portion that is connected to an outer conductor of the coaxial cable.

依據本發明，一個以上的接地線部未連接於同軸纜線之中心導體而是連接於外部導體，所以，能減少用以將中心導體連接並接地於接地線部之同軸纜線的條數。又，在連接於同軸纜線之側，信號線部及接地線部的間隔係與在相反側的等間隔P不同，同軸纜線之數量比信號線部與接地線部的總數還少，所以，能使用直徑比成為等間隔P的一側還大的同軸纜線，連接於信號線部之同軸纜線中至少一者的直徑大於間隔P。藉由減少同軸纜線的條數，以連接於信號線部的同軸纜線而言，能使用中心導體為大徑者，能大幅地改善傳送特性或雜訊特性等電性特性。即，依據本發明，能作成確保良好的電性特性且高密度安裝的同軸纜線線束，對於伴隨著電子機器之進一步的高性能化所致之資訊量的增大，能良好地因應。According to the present invention, since one or more grounding wire portions are not connected to the center conductor of the coaxial cable but are connected to the external conductor, the number of coaxial cables for connecting the center conductor to the grounding wire portion can be reduced. Further, on the side connected to the coaxial cable, the interval between the signal line portion and the ground line portion is different from the equal interval P on the opposite side, and the number of coaxial cables is smaller than the total number of the signal line portion and the ground line portion. A coaxial cable having a diameter larger than a side which is equal to the interval P can be used, and at least one of the coaxial cables connected to the signal line portion has a diameter larger than the interval P. By reducing the number of coaxial cables, the coaxial cable connected to the signal line portion can be used with a large diameter of the center conductor, and the electrical characteristics such as transmission characteristics and noise characteristics can be greatly improved. In other words, according to the present invention, it is possible to provide a coaxial cable harness that can be mounted at a high density while ensuring good electrical characteristics, and can cope with an increase in the amount of information accompanying further improvement in performance of the electronic device.
以下說明本發明之同軸纜線線束之實施形態的例子。又，本發明之同軸纜線線束可採用兩端側分別連接於中間基板的情形，或僅一端側連接於中間基板而另一端側附帶連接器的情形等各式各樣的形態，惟在此是針對一端側連接於中間基板的構造作說明。An example of an embodiment of the coaxial cable harness of the present invention will be described below. Further, the coaxial cable harness of the present invention may be connected to the intermediate substrate at both end sides, or may be of various forms such as the case where only one end side is connected to the intermediate substrate and the other end side is provided with a connector. The structure in which one end side is connected to the intermediate substrate will be described.
如第1圖所示，構成同軸纜線線束的同軸纜線11具有中心導體12、配設於中心導體12外周的內部絕緣體13、配設於內部絕緣體13外周的外部導體14、及配設於外部導體14外周之絕緣性的外覆層15，並將此等配設成同軸狀而構成。As shown in Fig. 1, the coaxial cable 11 constituting the coaxial cable harness has a center conductor 12, an internal insulator 13 disposed on the outer periphery of the center conductor 12, an outer conductor 14 disposed on the outer periphery of the inner insulator 13, and The insulating outer covering 15 on the outer circumference of the outer conductor 14 is configured to be coaxially arranged.
本發明不論同軸纜線11的粗細度。例如能使用依據AWG(America Wire Gauge)之規格所定的AWG28～46的纜線。例如，將間距設為0.5mm時，能使用AWG28～32的同軸纜線11。將間距設為0.3mm時，能使用AWG42的同軸纜線11。The present invention is not limited to the thickness of the coaxial cable 11. For example, a cable of AWG 28 to 46 according to the specifications of AWG (America Wire Gauge) can be used. For example, when the pitch is set to 0.5 mm, the coaxial cable 11 of AWGs 28 to 32 can be used. When the pitch is set to 0.3 mm, the coaxial cable 11 of the AWG 42 can be used.
其次，說明使用同軸纜線11的同軸纜線線束。(第1例)如第2圖所示，構成同軸纜線線束10之同軸纜線11的端部已作末端處理，從前端側中心導線12、內部絕緣體13及外部導體14分別依序階段地露出既定長度。如此般地已作末端處理之複數條同軸纜線11係連接於中間基板21。同軸纜線11係以其端部易連接於中間基板21的方式作成配列成平面狀的集合體，而端部以外也可加以捆束。Next, a coaxial cable harness using the coaxial cable 11 will be described. (First example) As shown in Fig. 2, the end portion of the coaxial cable 11 constituting the coaxial cable harness 10 has been subjected to end treatment, and the front end side center wire 12, the inner insulator 13 and the outer conductor 14 are sequentially and sequentially Exposed to a given length. A plurality of coaxial cables 11 that have been subjected to end processing in this manner are connected to the intermediate substrate 21. The coaxial cable 11 is formed as a flat assembly in such a manner that its end portions are easily connected to the intermediate substrate 21, and may be bundled in addition to the ends.
中間基板21具有連接面31，複數條同軸纜線11連接於此連接面31。此中間基板21係由例如具有金屬箔等配線圖案的可撓性基板或硬質基板構成。The intermediate substrate 21 has a connection surface 31 to which a plurality of coaxial cables 11 are connected. The intermediate substrate 21 is made of, for example, a flexible substrate or a rigid substrate having a wiring pattern such as a metal foil.
於連接面31，構成複數個帶狀的配線圖案之複數個信號線部32及複數個接地線部33係沿中間基板21的寬度方向交互地形成。信號線部32及接地線部33的前端部成為接點32a、33a。這些接點32a、33a係以既定等間隔的並列間距P配置。On the connection surface 31, a plurality of signal line portions 32 and a plurality of ground line portions 33 constituting a plurality of strip-shaped wiring patterns are alternately formed along the width direction of the intermediate substrate 21. The front end portions of the signal line portion 32 and the ground line portion 33 serve as contacts 32a and 33a. These contacts 32a, 33a are arranged at a juxtaposed pitch P at equal intervals.
配置於中間基板21的一側部側(第2圖的下側)的接地線部33，係以朝向中間基板21之連接方向後端側(連接同軸纜線之側(在第2圖中為右側))延伸，且在超過信號線部32與中心導體12連接的點後彎曲而朝向配線圖案之排列方向延伸的方式形成。此朝向配線圖案之排列方向延伸的部分成為連接部33b。配置於中間基板21之一側部側(在第2圖中為下側)的同軸纜線11a的外部導體14連接於此接地線部33的連接部33b。The grounding wire portion 33 disposed on one side of the intermediate substrate 21 (lower side in FIG. 2) is directed toward the rear end side of the connection direction of the intermediate substrate 21 (the side connecting the coaxial cable (in FIG. 2 The right side)) extends and is formed so as to be bent beyond the point where the signal line portion 32 is connected to the center conductor 12 and extends toward the arrangement direction of the wiring patterns. This portion extending toward the arrangement direction of the wiring pattern serves as the connection portion 33b. The outer conductor 14 of the coaxial cable 11a disposed on one side of the intermediate substrate 21 (the lower side in FIG. 2) is connected to the connecting portion 33b of the grounding wire portion 33.
未連接於外部導體14之其他接地線部33係銲接於同軸纜線11的中心導體12。中心導體12連接於接地線部33的同軸纜線11具有作為接地線的功能。另一方面，個別的信號線部32係銲接於同軸纜線11的中心導體12，這些線部具有用以傳送信號的功能。將信號線部32的條數設為m，將接地線部33的條數設為n，將同軸纜線11、11a的條數設為c2時，則「m≦c＜m+n」的關係成立。The other ground line portion 33 that is not connected to the outer conductor 14 is soldered to the center conductor 12 of the coaxial cable 11. The coaxial cable 11 to which the center conductor 12 is connected to the ground line portion 33 has a function as a ground line. On the other hand, the individual signal line portions 32 are soldered to the center conductor 12 of the coaxial cable 11, and these line portions have a function of transmitting signals. The number of the signal line portions 32 is m, the number of the ground line portions 33 is n, and when the number of the coaxial cables 11 and 11a is c2, "m≦c<m+n" The relationship is established.
如此般地，配置於中間基板21之一側部(在第2圖中為最下側)的接地線部33未連接於同軸纜線11的中心導體12，而是連接於配置在中間基板21之相同一側部之同軸纜線11a的外部導體14，所以，可省略連接於配置在中間基板21之一側部(在第2圖中為最下側)之接地線部33之份量的同軸纜線11，而能減少同軸纜線11的條數。藉此，能將構成同軸纜線線束10之同軸纜線11之全部或其中一者以上的直徑設成較大。In this manner, the ground line portion 33 disposed on one side of the intermediate substrate 21 (the lowermost side in FIG. 2) is not connected to the center conductor 12 of the coaxial cable 11, but is connected to the intermediate substrate 21 Since the outer conductor 14 of the coaxial cable 11a of the same side portion is coaxial, the coaxial portion connected to the ground line portion 33 disposed on one side (the lowermost side in FIG. 2) of the intermediate substrate 21 can be omitted. The cable 11 can reduce the number of coaxial cables 11. Thereby, the diameter of all or more of the coaxial cables 11 constituting the coaxial cable harness 10 can be made larger.
例如，在全部的接地線及信號線分別連接於同軸纜線之中心導體的情況下，必須有與全部的接地線及信號線相同數量的同軸纜線，以構成「c=m+n」的關係本發明中同軸纜線的條數比上述情況少，可按條數減少的程度，將同軸纜線11之全部或其中一者以上的中心導體的直徑設成較大。For example, when all the grounding wires and signal wires are respectively connected to the center conductor of the coaxial cable, it is necessary to have the same number of coaxial cables as the entire grounding wire and the signal wire to constitute "c=m+n". In the present invention, the number of the coaxial cables is smaller than the above-described case, and the diameter of the center conductor of all or one of the coaxial cables 11 can be made large in accordance with the degree of reduction of the number of strips.
本實施形態中，配置於中間基板21之一側部的同軸纜線11a，可使用其中心導體12的直徑比其他同軸纜線11之中心導體12的直徑還大，且全體的外徑亦為大直徑者。In the present embodiment, the coaxial cable 11a disposed on one side of the intermediate substrate 21 can have a larger diameter of the center conductor 12 than the center conductor 12 of the other coaxial cable 11, and the entire outer diameter is also Large diameter.
此情形下，一旦將其他同軸纜線11之並列間距設成與信號線部32及接地線部33相同的並列間距時，配置於中間基板21之一側部的同軸纜線11a的中心導體12不會配置成與所對應的信號線部32相同直線狀。所以，配置於中間基板21之一側部之大直徑的同軸纜線11a，係藉由彎曲其中心導體12而配置連接於其前端部對應的信號線部32。即，於中間基板21中，連接同軸纜線11、11a側的信號線部32及接地線部33的配列間距係與相反側之等間隔的並列間距P不同。In this case, when the parallel pitch of the other coaxial cables 11 is set to the same parallel pitch as the signal line portion 32 and the ground line portion 33, the center conductor 12 of the coaxial cable 11a disposed on one side of the intermediate substrate 21 is provided. It is not arranged in the same straight line as the corresponding signal line portion 32. Therefore, the large-diameter coaxial cable 11a disposed on one side of the intermediate substrate 21 is disposed so as to be connected to the signal line portion 32 corresponding to the tip end portion by bending the center conductor 12. In other words, in the intermediate substrate 21, the arrangement pitch of the signal line portion 32 and the ground line portion 33 on the side of the coaxial cable 11 and 11a is different from the parallel pitch P at the interval on the opposite side.
又，信號線部32或接地線部33與中心導體12的連接亦可不是利用銲料，而是利用導電性接著劑來進行。Further, the connection between the signal line portion 32 or the ground line portion 33 and the center conductor 12 may be performed not by solder but by a conductive adhesive.
各同軸纜線11、11a的外部導體14可安裝接地條38。配置於中間基板21之一側部(第2圖中的最下側)側的接地線部33係連接於同軸纜線11a的外部導體14，而且透過藉接地條38導通之其他同軸纜線11的外部導體14在另一端側接地。又，配置於中間基板21之一側部側的接地線部33以外的各接地線部33係在已連接之同軸纜線11之中心導體12的另一端側接地。The outer conductor 14 of each of the coaxial cables 11, 11a can be mounted with a ground bar 38. The grounding wire portion 33 disposed on one side of the intermediate substrate 21 (the lowermost side in FIG. 2) is connected to the outer conductor 14 of the coaxial cable 11a, and is passed through the other coaxial cable 11 that is electrically connected by the grounding bar 38. The outer conductor 14 is grounded at the other end side. Further, each of the grounding wire portions 33 other than the grounding wire portion 33 disposed on one side of the intermediate substrate 21 is grounded at the other end side of the center conductor 12 of the connected coaxial cable 11.
中間基板21係藉由從其前端側(第2圖的左側)插入而連接於設置在電子機器等之電路基板之連接器的插座(receptacle)。藉此，中間基板21的接點32a、33a導通接觸於插座側的端子，而與設置有插座之電路基板側的配線導通。The intermediate substrate 21 is connected to a receptacle of a connector provided on a circuit board of an electronic device or the like by being inserted from the front end side (the left side of FIG. 2). Thereby, the contacts 32a and 33a of the intermediate substrate 21 are electrically connected to the terminals on the socket side, and are electrically connected to the wiring on the circuit board side where the socket is provided.
又，亦可作成於此中間基板21之前端側安裝連接器並與設置在電子機器等之電路基板的連接器連接之構成。又，朝向電路基板的連接方向亦可為與電路基板之面正交的方向或沿著電路基板之面的方向之任一者。Further, a configuration may be adopted in which a connector is attached to the front end side of the intermediate substrate 21 and connected to a connector provided on a circuit board of an electronic device or the like. Further, the connection direction to the circuit board may be either a direction orthogonal to the surface of the circuit board or a direction along the surface of the circuit board.
又，同軸纜線線束10亦可為中間基板21上的同軸纜線11之連接位置的配列係沿著同軸纜線11之長度方向的L型構造(參照第3圖(a))。或，亦可為中間基板21上的同軸纜線11之連接位置的配列係與同軸纜線11之長度方向正交的T型構造(參照第3圖(b))。Further, the coaxial cable harness 10 may be an L-shaped structure in which the connection position of the coaxial cable 11 on the intermediate substrate 21 is along the longitudinal direction of the coaxial cable 11 (see FIG. 3(a)). Alternatively, the arrangement of the connection positions of the coaxial cables 11 on the intermediate substrate 21 may be a T-shaped structure orthogonal to the longitudinal direction of the coaxial cable 11 (see FIG. 3(b)).
依據本實施形態，由於接地線部33中的一個未連接於同軸纜線11的中心導體12，而是連接於一個同軸纜線11a的外部導體14，所以，能減少用以將中心導體12連接並接地於接地線部33之同軸纜線11、11a的條數。藉由減少同軸纜線11的條數，以連接於信號線部32的同軸纜線11、11a而言，能使用中心導體12為大直徑者，能改善傳送特性或雜訊特性等電性特性。According to the present embodiment, since one of the ground line portions 33 is not connected to the center conductor 12 of the coaxial cable 11, but is connected to the outer conductor 14 of one coaxial cable 11a, the center conductor 12 can be reduced. And the number of coaxial cables 11, 11a grounded to the ground line portion 33. By reducing the number of the coaxial cables 11, the coaxial cables 11 and 11a connected to the signal line portion 32 can use the center conductor 12 as a large diameter, and can improve the electrical characteristics such as transmission characteristics or noise characteristics. .
例如，將一條同軸纜線11a的直徑作成粗大的情況下，若是將不粗大的同軸纜線11的直徑W設為間距P以下(W≦P)，則能使作成粗大的同軸纜線11a之直徑Wa大於間距P(Wa＞P)。For example, when the diameter of one coaxial cable 11a is made thick, if the diameter W of the coaxial cable 11 which is not thick is set to a pitch P or less (W≦P), the coarse coaxial cable 11a can be made. The diameter Wa is larger than the pitch P (Wa>P).
又，由於中間基板21之接地線部33中至少一者連接於同軸纜線11、11a的外部導體14，並透過其外部導體14接地，所以，回饋電流路徑成為小的迴路，而能使電性特性變佳。即，能確保良好的電性特性且高密度安裝的同軸纜線線束10，對於伴隨著電子機器之進一步的高性能化所造成資訊量的增大，能良好地因應。Further, since at least one of the ground line portions 33 of the intermediate substrate 21 is connected to the outer conductor 14 of the coaxial cables 11 and 11a and is grounded through the outer conductor 14, the feedback current path becomes a small loop and enables electricity. Sexual characteristics have improved. In other words, the coaxial cable harness 10 which can ensure high electrical characteristics and is mounted at a high density can be satisfactorily affected by an increase in the amount of information accompanying further improvement in performance of the electronic device.
又，本實施形態，係一個接地線部33未連接同軸纜線11a的中心導體12，而是連接於一條同軸纜線11a的外部導體14，惟未連接於中心導體12而連接於外部導體14之接地線部33的條數及將接地線部33連接於外部導體14之同軸纜線11的數量亦可為一條以上。Further, in the present embodiment, one grounding wire portion 33 is not connected to the center conductor 12 of the coaxial cable 11a, but is connected to the outer conductor 14 of one coaxial cable 11a, but is not connected to the center conductor 12 and is connected to the outer conductor 14 The number of the grounding wire portions 33 and the number of the coaxial cables 11 connecting the grounding wire portions 33 to the outer conductors 14 may be one or more.
又，未連接中心導體12而連接於外部導體14之接地線部33及此接地線部33連接於外部導體14的同軸纜線11，均不限定於中間基板21之一側部者。Further, the ground line portion 33 connected to the outer conductor 14 without connecting the center conductor 12 and the coaxial cable 11 to which the ground line portion 33 is connected to the outer conductor 14 are not limited to one side of the intermediate substrate 21.
又，為了使各同軸纜線11整齊排列來固定以及為了外部導體14之接地電位的均一化，以設置接地條38為佳。倘若即便無此接地條38，同軸纜線11也能良好地固定的話，也可無此接地條38。Further, in order to fix the coaxial cables 11 in order and to uniformize the ground potential of the outer conductor 14, it is preferable to provide the ground bar 38. If the coaxial cable 11 can be well fixed even without the grounding strip 38, the grounding strip 38 can be omitted.
其次，說明本發明之其他形態例。(第2例)第4圖所示的例子中，係設成任一信號線部32及接地線部33的兩端部在中間基板21的寬度方向為不同位置。Next, other examples of the invention will be described. (Example 2) In the example shown in FIG. 4, both end portions of any of the signal line portion 32 and the ground line portion 33 are different in the width direction of the intermediate substrate 21.
在此種配置中，信號線部32及接地線部33係在與中心導體12的連接處和接點(第4圖中為左端)32a、33a之間彎曲。又，連接於同軸纜線11a之外部導體14的接地線部33係配合其相鄰之信號線部32的彎曲來變更寬度尺寸。In such an arrangement, the signal line portion 32 and the ground line portion 33 are bent between the connection with the center conductor 12 and the contact (left end in FIG. 4) 32a, 33a. Further, the ground line portion 33 connected to the outer conductor 14 of the coaxial cable 11a is changed in width by the curvature of the adjacent signal line portion 32.
此第2例中，使信號線部32及接地線部33的配線圖案在中途彎曲或改變配線圖案的寬度尺寸，藉此不用改變接點32a、33a的間距P，而於包含大直徑的同軸纜線11a之全部的同軸纜線11中，能在不將其中心導體12彎曲的情況下連接於信號線部32或接地線部33。In the second example, the wiring pattern of the signal line portion 32 and the ground line portion 33 is bent or the width dimension of the wiring pattern is changed in the middle, whereby the pitch P of the contacts 32a, 33a is not changed, and the coaxial line including the large diameter is included. The coaxial cable 11 of all the cables 11a can be connected to the signal line portion 32 or the ground line portion 33 without bending the center conductor 12.
依據此同軸纜線線束10，可不需要於中心導體12連接時的彎曲作業，能容易進行將同軸纜線11與中間基板12連接的作業。又，在使各同軸纜線11例如均等地大直徑化的情況下，不用改變接點32a、33a的間距P即能使同軸纜線11的間距均等。According to this coaxial cable harness 10, it is possible to easily perform the work of connecting the coaxial cable 11 and the intermediate substrate 12 without bending the center conductor 12 when it is connected. Further, when the coaxial cables 11 are, for example, uniformly increased in diameter, the pitch of the coaxial cables 11 can be made uniform without changing the pitch P of the contacts 32a and 33a.
(第3例)第5圖所示的例子是第4圖所示之例子的變形例，且是將各同軸纜線11的直徑作成粗大的例子。此第3例的情形也是在中途彎曲信號線部32及接地線部33的配線圖案，藉此不用改變接點32a、33a的間距P，而於全部的同軸纜線11中，能在不彎曲其中心導體12的情況下連接於信號線部32或接地線部33。(Example 3) The example shown in Fig. 5 is a modification of the example shown in Fig. 4, and is an example in which the diameter of each coaxial cable 11 is made thick. In the case of the third example, the wiring pattern of the signal line portion 32 and the ground line portion 33 is also bent in the middle, whereby the pitch P of the contacts 32a, 33a is not changed, and the coaxial cable 11 can be bent without being bent. In the case of the center conductor 12, it is connected to the signal line portion 32 or the ground line portion 33.
此構造之同軸纜線線束10的情況也可不需要於中心導體12連接時的彎曲作業，能容易地進行將同軸纜線11與中間基板12連接的作業。又，例如藉由使各同軸纜線11均等地大直徑化，能謀求中心導體12的大直徑化所致之電性特性的改善。In the case of the coaxial cable harness 10 of this configuration, the bending work when the center conductor 12 is connected is not required, and the work of connecting the coaxial cable 11 to the intermediate substrate 12 can be easily performed. Moreover, for example, by making each of the coaxial cables 11 uniform in diameter, it is possible to improve the electrical characteristics of the center conductor 12 by increasing the diameter.
(第4例)第6圖所示的例子為，將各接地線部33以朝中間基板21的後端(第6圖之右)延伸的方式形成，而且以分別朝側方(中間基板的寬度方向)延伸的方式形成連接部33b。接地線部33比信號線部32還長。使各同軸纜線11的外部導體14連接於這些接地線部33之個別的連接部33b。接地線部33未與接地線用的同軸纜線11連接，而係透過信號線用的同軸纜線11的外部導體14接地。當利用接地條38連接全部的外部導體14時，則各接地線用的同軸纜線11透過全部的外部導體14與同軸纜線側的接地電路接地，能將各接地線部33的電位予以均等化。(Fourth example) The example shown in Fig. 6 is such that each of the grounding wire portions 33 is formed to extend toward the rear end of the intermediate substrate 21 (the right side of Fig. 6), and is respectively directed to the side (the intermediate substrate) The connecting portion 33b is formed in such a manner that the width direction extends. The ground line portion 33 is longer than the signal line portion 32. The outer conductors 14 of the respective coaxial cables 11 are connected to the individual connection portions 33b of the ground line portions 33. The grounding wire portion 33 is not connected to the coaxial cable 11 for the grounding wire, but is grounded to the outer conductor 14 of the coaxial cable 11 for transmitting the signal wire. When all the outer conductors 14 are connected by the grounding strips 38, the coaxial cables 11 for the respective grounding wires are grounded through the grounding circuits on the coaxial cable side through all the outer conductors 14, and the potentials of the respective grounding wire portions 33 can be equalized. Chemical.
依據此構造的同軸纜線線束10，能減少同軸纜線11的條數，能謀求連接於信號線部32之同軸纜線11之中心導體12的大直徑化所致之電性特性的改善。According to the coaxial cable harness 10 of this configuration, the number of the coaxial cables 11 can be reduced, and the electrical characteristics of the center conductor 12 connected to the coaxial cable 11 of the signal line portion 32 can be improved.
(第5例)第7圖所示的例子為，將各接地線部33形成朝中間基板21的後端(第7圖之右)側延伸，而且使在後端形成朝側方(中間基板的寬度方向)延伸之連接部33b連結而構成一體連接部33c。使各同軸纜線11的外部導體14連接於此一體連接部33c。(Example 5) The example shown in Fig. 7 is such that each of the grounding wire portions 33 is formed to extend toward the rear end (the right side of Fig. 7) of the intermediate substrate 21, and is formed to be laterally formed at the rear end (intermediate substrate). The connecting portions 33b extending in the width direction are coupled to each other to constitute an integral connecting portion 33c. The outer conductor 14 of each coaxial cable 11 is connected to the integral connecting portion 33c.
在此構造之同軸纜線線束10中，接地線部33未與接地線用的同軸纜線連接，而是透過信號線用之同軸纜線11的外部導體14來接地。能減少同軸纜線11的條數，能謀求以連接於信號線部32之同軸纜線11之中心導體12的大直徑化所致之電性特性的改善。又，若藉著銲料等將各外部導體14連接於一體連接部33c，即使不使用接地條38，也能使各接地線部33的電位均等化。In the coaxial cable harness 10 of this configuration, the grounding wire portion 33 is not connected to the coaxial cable for the grounding wire, but is grounded through the outer conductor 14 of the coaxial cable 11 for the signal wire. The number of the coaxial cables 11 can be reduced, and the electrical characteristics of the center conductor 12 connected to the coaxial cable 11 of the signal line portion 32 can be improved. Further, when the external conductors 14 are connected to the integral connecting portion 33c by solder or the like, the potential of each of the grounding wire portions 33 can be equalized without using the grounding strips 38.
(第6例)第8圖所示的例子為，將各接地線部33形成朝向中間基板21的後端(第8圖之右)側延伸，而且使在後端形成朝側方(中間基板的寬度方向)延伸之連接部33b按任意的每個單位條數連結而構成一體連接部33c。使各同軸纜線11的外部導體14連接於此一體連接部33c。(Example 6) The example shown in Fig. 8 is such that each of the grounding wire portions 33 is formed to extend toward the rear end (the right side of Fig. 8) of the intermediate substrate 21, and is formed to be laterally formed at the rear end (intermediate substrate). The connecting portion 33b extending in the width direction is connected to each of the arbitrary number of units to constitute the integral connecting portion 33c. The outer conductor 14 of each coaxial cable 11 is connected to the integral connecting portion 33c.
此構造之同軸纜線線束10中，接地線部33不與接地線用的同軸纜線連接，而是透過信號線用之同軸纜線11的外部導體14來接地。能減少同軸纜線11的條數，能謀求連接於信號線部32之同軸纜線11之中心導體12的大直徑化所致之電性特性的改善。又，此情形下，藉著上焊以將各外部導體14連接於一體連接部33c的話，即使是不使用接地條38，也能使各接地線部33的電位於每一單位條數均等化。In the coaxial cable harness 10 of this configuration, the grounding wire portion 33 is not connected to the coaxial cable for the grounding wire, but is grounded through the outer conductor 14 of the coaxial cable 11 for signal wires. The number of the coaxial cables 11 can be reduced, and the electrical characteristics of the center conductor 12 connected to the coaxial cable 11 of the signal line portion 32 can be improved. Further, in this case, by connecting the outer conductors 14 to the integral connecting portion 33c by the upper welding, even if the grounding strip 38 is not used, the electric power of each of the grounding wires 33 can be equalized per unit number. .
(第7例)第9圖所示的例子是表示信號線部32彼此鄰接的構造。又，將各接地線部33形成朝向中間基板21的後端(第9圖之右)延伸，而且使在後端朝向側方(中間基板的寬度方向)延伸的連接部33b連結而構成一體連接部33c，使各同軸纜線11的外部導體14連接於此一體連接部33c。在以未夾著接地線部33而鄰接的信號線部32進行差動傳送的情況下，能使用此配線。(Example 7) The example shown in Fig. 9 is a structure in which the signal line portions 32 are adjacent to each other. Further, each of the grounding wire portions 33 is formed to extend toward the rear end (the right side of the ninth figure) of the intermediate substrate 21, and the connecting portions 33b extending toward the side (the width direction of the intermediate substrate) at the rear end are connected to each other to form an integral connection. The portion 33c connects the outer conductor 14 of each coaxial cable 11 to the integral connecting portion 33c. This wiring can be used when the signal line portion 32 adjacent to the ground line portion 33 is not differentially transferred.
依據此構造的同軸纜線線束10，接地線部33不與接地線用的同軸纜線連接，而是透過信號線用之同軸纜線11的外部導體14來接地。According to the coaxial cable harness 10 of this configuration, the grounding wire portion 33 is not connected to the coaxial cable for the grounding wire, but is grounded through the outer conductor 14 of the coaxial cable 11 for the signal wire.
此情況下，能減少同軸纜線11的條數，能謀求連接於信號線部32之同軸纜線11之中心導體12的大直徑化所致之電性特性的改善。又，若藉著銲料將各外部導體14連接於一體連接部33c，即使不使用接地條38，也能謀求各接地線部33的電位均等化。In this case, the number of the coaxial cables 11 can be reduced, and the electrical characteristics of the center conductor 12 connected to the coaxial cable 11 of the signal line portion 32 can be improved. Further, when the external conductors 14 are connected to the integral connection portion 33c by solder, even if the ground bar 38 is not used, the potential of each of the ground line portions 33 can be equalized.
