本発明は、フラット回路体と端子金具との電気的な導通をとるための導体接続構造に関する。   The present invention relates to a conductor connection structure for establishing electrical continuity between a flat circuit body and a terminal fitting.

フラット回路体と端子金具との電気的な導通をとるための導体接続構造に係る技術は、例えば下記特許文献1に開示される。   A technique related to a conductor connection structure for establishing electrical continuity between a flat circuit body and a terminal fitting is disclosed in, for example, Patent Document 1 below.

フラット回路体としては、FPC(Flexible Printed Circuit)やFFC(Flexible Fiat Cable)などが挙げられ、例えば各種電子機器の内部配線に使用される。近年では、自動車等の移動体の配線にも使用される。   Examples of the flat circuit body include FPC (Flexible Printed Circuit) and FFC (Flexible Fiat Cable), and are used for internal wiring of various electronic devices, for example. In recent years, it is also used for wiring of mobile objects such as automobiles.

特開昭50−100585号公報Japanese Patent Laid-Open No. 50-100585

特許文献1に開示された従来技術にあっては、端子金具の導体接続部に、先端の尖った歯が複数形成される。この先端の尖った歯は、フラット回路体における絶縁体部分に先ず突き刺され、この後に内側に曲げ返されて再度フラット回路体に突き刺され、最終的には歯の先端が導体に接触する。このような導体接続構造であることから、接続信頼性に係る幾つかの問題点を有する。   In the prior art disclosed in Patent Document 1, a plurality of teeth with sharp tips are formed in the conductor connection portion of the terminal fitting. The sharp tooth at the tip is first stabbed into the insulator portion of the flat circuit body, then bent back inward and stabbed into the flat circuit body again, and finally the tip of the tooth contacts the conductor. Since it is such a conductor connection structure, it has some problems related to connection reliability.

In addition, when the teeth break through the conductor, the contact pressure decreases and the contact resistance increases. Therefore, there is a problem that the crimp height needs to be controlled severely in order to prevent them.

さらに、フラット回路体の位置ズレが生じてしまうと、導体との接触圧力が低下するとともに接触抵抗が増加することから、これらを防止するためとしてフラット回路体の位置決めをシビアにする必要があるという問題点を有する。さらにまた、歯の先端が導体に接触する導体接続構造であることから、接触面積が小さく、このため接触抵抗が増加し易いという問題点を有する。   Furthermore, if the displacement of the flat circuit body occurs, the contact pressure with the conductor decreases and the contact resistance increases. Therefore, it is necessary to position the flat circuit body severely in order to prevent them. Has a problem. Furthermore, since it is a conductor connection structure in which the tip of the tooth contacts the conductor, there is a problem that the contact area is small, and therefore the contact resistance tends to increase.

To do.

図1において、引用符号1はフラット回路体を示す。このフラット回路体1は、FPC(Flexible Printed Circuit)やFFC(Flexible Fiat Cable)であり、本実施例においては、自動車等の移動体の配線に使用される。フラット回路体1が移動体に使用される理由としては、特に限定するものでないが、ワイヤハーネスの薄型軽量化を図ることができるからである。   In FIG. 1, reference numeral 1 indicates a flat circuit body. The flat circuit body 1 is an FPC (Flexible Printed Circuit) or FFC (Flexible Fiat Cable), and is used for wiring of a moving body such as an automobile in this embodiment. Although the reason why the flat circuit body 1 is used for the moving body is not particularly limited, it is possible to reduce the thickness and weight of the wire harness.

一般的な電線が使用される場合にあっては、ワイヤハーネスの占有スペースや重さが大きくなってしまうという虞があるが、フラット回路体1であれば、そのようなことはない。   When a general electric wire is used, there is a possibility that the occupied space and weight of the wire harness will be increased. However, if the flat circuit body 1 is used, this is not the case.

フラット回路体1は、導体2と、この導体2を被覆する絶縁体3とを備えて構成される。フラット回路体1は、偏平な帯状に形成される。尚、図中のフラット回路体1は、導体2が一本のみ示されるがこの限りでないものとする。すなわち、複数本であってもよいものとする。この場合、複数の導体2は所定間隔で並べられ、これら複数の導体2を覆うように絶縁体3が設けられるものとする。   The flat circuit body 1 includes a conductor 2 and an insulator 3 that covers the conductor 2. The flat circuit body 1 is formed in a flat band shape. The flat circuit body 1 in the figure shows only one conductor 2, but this is not the case. That is, it may be a plurality. In this case, the plurality of conductors 2 are arranged at predetermined intervals, and the insulator 3 is provided so as to cover the plurality of conductors 2.

導体2は、所定の幅寸法で真っ直ぐにのびる帯状に形成される。導体2は、銅や銅合金等の導電性を有する金属材料からなる。導体2は、これ自身に外力が加わった場合に、破れ等の破損がない程度の厚みを有する。また、導体2は、外力が加わった場合に、曲がる等の変形が可能な厚みを有する。   The conductor 2 is formed in a belt shape extending straight with a predetermined width dimension. The conductor 2 is made of a conductive metal material such as copper or a copper alloy. The conductor 2 has a thickness that does not cause breakage or the like when an external force is applied to the conductor 2. The conductor 2 has a thickness that allows deformation such as bending when an external force is applied.

絶縁体3は、絶縁性を有する樹脂材料からなる。絶縁体3は、FPCやFFCに応じて、フィルム状に形成されたり、押出成型により所定の厚みを有するように形成されたりする。   The insulator 3 is made of an insulating resin material. The insulator 3 is formed in a film shape or has a predetermined thickness by extrusion molding according to FPC or FFC.

以上のようなフラット回路体1は、この端末部分において所定長さで絶縁体3が除去(所定範囲で絶縁体3を除去)される。これにより、導体2が露出(剥き出し状態)し、露出した部分を介して端子金具4との電気的な導通をとることができるようになる。   In the flat circuit body 1 as described above, the insulator 3 is removed at a predetermined length at this terminal portion (the insulator 3 is removed within a predetermined range). As a result, the conductor 2 is exposed (exposed), and electrical continuity with the terminal fitting 4 can be established through the exposed portion.

端子金具4は、図示しない相手側端子金具との電気的接触部分として形成される電気接触部5と、フラット回路体1の導体2との電気的な導通をとる部分として形成される導体接続部6とを有する。端子金具4は、導電性を有する金属板を所定の展開形状に打ち抜いた後、曲げ等を施して例えば図示のような形状に形成される。   The terminal fitting 4 is a conductor connection portion formed as an electrical contact portion 5 that is formed as an electrical contact portion with a mating terminal fitting (not shown) and a portion that is electrically connected to the conductor 2 of the flat circuit body 1. 6. The terminal fitting 4 is formed, for example, in the shape shown in the figure by punching a conductive metal plate into a predetermined developed shape and then bending it.

尚、端子金具4は、本実施例において電気接触部5の部分が雌型となる形状であるが、この限りでないものとする。すなわち、雄型となる形状であってもよいものとする。   In addition, although the terminal metal fitting 4 is a shape from which the part of the electrical contact part 5 becomes a female type in a present Example, it shall not be this limitation. That is, it may be a male shape.

電気接触部5は、上記の如く雌型となる形状に形成される。具体的には、断面矩形の筒形状に形成される。このような電気接触部5の内部には、片持ち形状となる図示しない弾性接触片が形成される。弾性接触片は、図示しない相手側端子金具の雄型となる電気接触部に対し、弾力性を持って電気的に接触する部分として形成される。電気接触部5は、相手側端子金具の電気接触部に応じた長さに形成される。   The electrical contact portion 5 is formed in a female shape as described above. Specifically, it is formed in a cylindrical shape having a rectangular cross section. An elastic contact piece (not shown) having a cantilever shape is formed inside the electrical contact portion 5. The elastic contact piece is formed as a portion that comes into electrical contact with elasticity to an electrical contact portion that is a male shape of a mating terminal fitting (not shown). The electrical contact portion 5 is formed in a length corresponding to the electrical contact portion of the mating terminal fitting.

導体接続部6は、電気接触部5に連成される。このような導体接続部6は、フラット回路体1の導体2を挟み込んで電気的な導通をとることができるように形成される。具体的には、第一導体挟持部7と、第二導体挟持部8と、連結折り曲げ部9とを有し、これら各部分により導体2を挟み込んで電気的な導通をとることができるように形成される。   The conductor connection portion 6 is coupled to the electrical contact portion 5. Such a conductor connection portion 6 is formed so as to be electrically conductive by sandwiching the conductor 2 of the flat circuit body 1. Specifically, it has the 1st conductor clamping part 7, the 2nd conductor clamping part 8, and the connection bending part 9, so that the conductor 2 can be pinched | interposed by these each part and electrical continuity can be taken. It is formed.

尚、導体接続部6は、以下の説明から分かるようになるが、第一導体挟持部7及び第二導体挟持部8にて導体2を挟み込んでも、この導体2へのダメージを引き起こすようなことはない。   As will be understood from the following description, the conductor connecting portion 6 may cause damage to the conductor 2 even if the conductor 2 is sandwiched between the first conductor sandwiching portion 7 and the second conductor sandwiching portion 8. There is no.

第一導体挟持部7は、板状の第一板状部10と、この第一板状部10に形成される突出部11とを有する。第一板状部10は、端子金具4が金属板からなることから、上記の如く板状に形成される。また、第一板状部10は、導体接続部6における端子金具4の底板に相当する部分として帯状に形成される。このような第一板状部10は、電気接触部5における端子金具4の底板に相当する部分に連成される。   The first conductor holding portion 7 includes a plate-like first plate-like portion 10 and a protruding portion 11 formed on the first plate-like portion 10. The first plate portion 10 is formed in a plate shape as described above because the terminal fitting 4 is made of a metal plate. Further, the first plate-like portion 10 is formed in a band shape as a portion corresponding to the bottom plate of the terminal fitting 4 in the conductor connecting portion 6. Such a first plate-like portion 10 is coupled to a portion corresponding to the bottom plate of the terminal fitting 4 in the electrical contact portion 5.

第一板状部10は、端子金具4の軸方向に沿って長く形成される。第一板状部10における引用符号12は、フラット回路体1の導体2に対する導体対向面を示す。また、引用符号13は、導体対向面12の反対側となる端子底面を示す。   The first plate-like portion 10 is formed long along the axial direction of the terminal fitting 4. Reference numeral 12 in the first plate-like portion 10 indicates a conductor facing surface with respect to the conductor 2 of the flat circuit body 1. Reference numeral 13 indicates a terminal bottom surface on the opposite side of the conductor facing surface 12.

第一板状部10には、突出部11が二つ形成される(数は一例であるものとする)。この二つの突出部11は、導体接続部6の長手方向(端子金具4の軸方向)に所定の間隔をあけて配置形成される。   Two projecting portions 11 are formed on the first plate-like portion 10 (the number is an example). The two protruding portions 11 are arranged and formed at a predetermined interval in the longitudinal direction of the conductor connecting portion 6 (the axial direction of the terminal fitting 4).

本実施例においては、二つの突出部11の各中心軸が第一板状部10の中心軸に合うように配置形成される。二つの突出部11は、特に限定するものでないが、同じ形状及びサイズに形成される。以下、片方の突出部11について説明をする。   In the present embodiment, the central axes of the two protruding portions 11 are arranged and formed so as to match the central axis of the first plate-like portion 10. Although the two protrusion parts 11 are not specifically limited, they are formed in the same shape and size. Hereinafter, the one protrusion part 11 is demonstrated.

突出部11は、導体対向面12から突出する突出部分として形成される。本実施例においては、端子底面13を凹ませて導体対向面12を凸にするような打ち出し形状に形成される。具体的には、ドーム状となるインデント形状に形成される。   The protruding portion 11 is formed as a protruding portion protruding from the conductor facing surface 12. In the present embodiment, it is formed in a punched shape in which the terminal bottom surface 13 is recessed and the conductor facing surface 12 is convex. Specifically, it is formed in an indent shape that becomes a dome shape.

尚、突出部11は、上記ドーム状に限らず、例えば半球状であってもよいものとする。また、後述する実施例2や実施例3の形状であってもよいものとする。突出部11は、滑らかな曲面を有するように形成される(全体を曲面にしなくてもよいものとする。突出部11の変形例に関しては、突出先端に若干の平面を持たせてフラット回路体1の導体2に対する小さな載置部を形成してもよいものとする)。   In addition, the protrusion part 11 shall not be restricted to the said dome shape, for example, hemisphere shall be sufficient. Moreover, the shape of Example 2 or Example 3 described later may be used. The projecting portion 11 is formed to have a smooth curved surface (the entire surface does not have to be a curved surface. With respect to the modified example of the projecting portion 11, a flat circuit body is provided with a slight flat surface at the projecting tip. A small mounting portion for one conductor 2 may be formed).

第二導体挟持部8は、板状の第二板状部14と、この第二板状部14に形成される貫通孔15とを有する。第二板状部14は、端子金具4が金属板からなることから、上記の如く板状に形成される。また、第二板状部14は、フラット回路体1の導体2を介在させた状態で第一板状部10に対し重ね合わせられるような部分として帯状に形成される。第二板状部14は、端子金具4の軸方向に沿って長く形成される。このような第二板状部14は、連結折り曲げ部9を介して第一板状部10に連成される。   The second conductor holding portion 8 has a plate-like second plate-like portion 14 and a through hole 15 formed in the second plate-like portion 14. The second plate-like portion 14 is formed in a plate shape as described above because the terminal fitting 4 is made of a metal plate. Further, the second plate-like portion 14 is formed in a band shape as a portion that overlaps the first plate-like portion 10 with the conductor 2 of the flat circuit body 1 interposed. The second plate-like portion 14 is formed long along the axial direction of the terminal fitting 4. Such a second plate-like portion 14 is coupled to the first plate-like portion 10 via the connecting bent portion 9.

第二板状部14には、貫通孔15が二つ形成される(数は一例であるものとする)。この二つの貫通孔15は、導体接続部6の長手方向(端子金具4の軸方向)に所定の間隔をあけて配置形成される。具体的には、突出部11の位置に合わせて配置形成される。貫通孔15は、フラット回路体1の導体2の厚みに配慮して、また、後述する導体2の変形に配慮して、突出部11よりも一回り大きなサイズで貫通するように形成される。   Two through holes 15 are formed in the second plate-like portion 14 (the number is an example). The two through holes 15 are arranged and formed at a predetermined interval in the longitudinal direction of the conductor connecting portion 6 (the axial direction of the terminal fitting 4).
