Description

本発明は、平型導体用電気コネクタに関する。   The present invention relates to an electrical connector for a flat conductor.

ＦＰＣ等の平型導体の長手方向で先端側に設けられた接続部分との接触接続のための接触部と回路基板への接続のための接続部とを備えた複数の端子と、該端子をコネクタ幅方向に配列保持するハウジングとを有し、該ハウジングが、上壁と下壁そして両方の側壁で形成される周壁の後部で、前方に向け平型導体の接続部分を受け入れる受入部を形成する導入壁部を有し、接続部分に接触する上記端子の接触部が上記受入部内に位置している平型導体用電気コネクタが回路基板に取り付けられるコネクタとして広く用いられている。   A plurality of terminals including a contact portion for contact connection with a connection portion provided on the tip side in the longitudinal direction of a flat conductor such as an FPC, and a connection portion for connection to a circuit board; A housing that is arranged and held in the connector width direction, and the housing forms a receiving portion for receiving a connecting portion of a flat conductor toward the front at a rear portion of a peripheral wall formed by an upper wall, a lower wall, and both side walls. An electrical connector for a flat conductor in which a contact portion of the terminal that contacts the connecting portion is located in the receiving portion is widely used as a connector that is attached to a circuit board.

かかる平型導体用電気コネクタは、平型導体の長手方向に対して直角な幅方向で、該平型導体の先端縁に多数の接続部分が細ピッチで配置されていて、それぞれが、幅方向にコネクタに配列された端子の接触部に対応して接触接続する。したがって、各接続部分を対応する端子の接触部と確実に接触させるには、平型導体の受入部への導入に際し、平型導体はその幅方向で正確に位置していなければならない。   Such an electrical connector for a flat conductor has a width direction perpendicular to the longitudinal direction of the flat conductor, and a large number of connecting portions are arranged at a fine pitch at the leading edge of the flat conductor, The contacts are connected in correspondence with the contact portions of the terminals arranged in the connector. Therefore, in order to ensure that each connection portion is brought into contact with the contact portion of the corresponding terminal, when the flat conductor is introduced into the receiving portion, the flat conductor must be accurately positioned in the width direction.

この種のコネクタと開示する特許文献１では、平型導体としてのＦＰＣ等をその幅方向で位置決めして収めるための嵌合口の入口部にテーパ面の部分を設け、平型導体が嵌合口への導入開始時に多少幅方向にずれていても、該平型導体はその側縁先端が上記テーパ面に沿って案内され正規の幅方向位置に導かれて、上記嵌合口へ進入し、嵌合口内で正規位置で上記接続部分と接触部が対応して接触接続されるようになっている。   In this type of connector and disclosed in Patent Document 1, a tapered surface portion is provided at an inlet portion of a fitting port for positioning and storing an FPC or the like as a flat conductor in the width direction, and the flat conductor is connected to the fitting port. Even if it is slightly shifted in the width direction at the start of introduction of the flat conductor, the end of the side edge of the flat conductor is guided along the tapered surface and guided to the normal width direction position, and enters the fitting port for fitting. The connection portion and the contact portion are correspondingly connected to each other at a normal position in the mouth.

特開２００４−１７８９５８JP 2004-178958 A

特許文献１では、端子はハウジングに対し前方と後方のそれぞれの方向から取り付けられる二種の端子を配列方向で交互に有していて、前方から取り付けられる端子の後端側に形成された、回路基板への半田接続のための接続部が、前後方向で、上記嵌合口の後端位置、すなわち入口端位置にまで延びている。上記接続部は、後端縁のみならず上縁もハウジングの部分より突出しており、平型導体を嵌合口に向け、水平方向、そして傾斜方向のいずれの方向から導入しても、該平型導体の先端はこの接続部に当接してしまう可能性が高い。   In Patent Document 1, the terminal has two types of terminals attached to the housing from the front and rear directions alternately in the arrangement direction, and is formed on the rear end side of the terminal attached from the front. A connecting portion for solder connection to the board extends in the front-rear direction to the rear end position of the fitting port, that is, the inlet end position. In the connection part, not only the rear end edge but also the upper edge protrudes from the housing part, and the flat type conductor is directed to either the horizontal direction or the inclined direction with the flat type conductor facing the fitting port. There is a high possibility that the tip of the conductor abuts on this connecting portion.

平型導体は母材が樹脂製であり、そして端子は金属できわめて薄いので、平型導体が端子の接続部へ当接すると、この端子の接続部により傷つけられ易い。平型導体は母材が樹脂製であるが、先端には回路線として金属の接続部分があり、損傷を受けると、平型導体の前端の削れにより、樹脂粉そして金属粉が生じ、これらが接触不良やショートの原因となることもあった。   Since the base material of the flat conductor is made of resin and the terminal is made of metal, the flat conductor is easily damaged when the flat conductor abuts against the terminal connection. The flat conductor is made of resin, but there is a metal connection part as a circuit line at the tip. If it is damaged, the front end of the flat conductor is scraped to produce resin powder and metal powder. It could cause poor contact or short circuit.

本発明は、このような事情に鑑み、平型導体の導入開始時、平型導体を端子との当接により傷めることなく、所定導入位置へ案内できる平型導体用電気コネクタを提供することを課題とする。   In view of such circumstances, the present invention provides an electrical connector for a flat conductor that can guide a flat conductor to a predetermined introduction position without damaging the flat conductor due to contact with a terminal at the start of introduction of the flat conductor. Let it be an issue.

本発明に係る平型導体用電気コネクタは、平型導体の長手方向で先端側に設けられた接続部分との接触接続のための接触部と回路基板への接続のための接続部とを備えた複数の端子と、該端子をコネクタ幅方向に配列保持するハウジングとを有し、該ハウジングは、上壁と下壁そして両方の側壁で形成される周壁の後部で、前方に向け平型導体の接続部分を受け入れる受入部を形成する導入壁部を有し、接続部分に接触する上記端子の接触部が上記受入部内に位置している。   An electrical connector for a flat conductor according to the present invention includes a contact portion for contact connection with a connection portion provided on the distal end side in the longitudinal direction of the flat conductor and a connection portion for connection to a circuit board. A plurality of terminals, and a housing for arranging and holding the terminals in the connector width direction, the housing being a flat conductor facing forward at the rear part of the peripheral wall formed by the upper wall, the lower wall, and both side walls. And a contact portion of the terminal that contacts the connecting portion is located in the receiving portion.

かかる平型導体用電気コネクタにおいて、本発明では、導入壁部は上壁の後端が少なくとも平型導体の幅方向範囲で、下壁の後端よりも前方に位置していて、下壁の上面が上壁の後端よりも後方で上方に露呈する露呈面を有し、該露呈面がコネクタ幅方向での上記接続部の配列域外で該接続部の上縁よりも上方に位置していて、平型導体を受入部へ向けて導入する過程で該平型導体の先端縁が上記露呈面に当接可能となっていることを特徴としている。   In such an electrical connector for a flat conductor, in the present invention, the introduction wall portion has a rear end of the upper wall at least in the width direction range of the flat conductor, and is positioned forward of the rear end of the lower wall, The upper surface has an exposed surface that is exposed upward and behind the rear end of the upper wall, and the exposed surface is positioned above the upper edge of the connecting portion outside the arrangement region of the connecting portions in the connector width direction. In the process of introducing the flat conductor toward the receiving portion, the leading edge of the flat conductor can be brought into contact with the exposed surface.

このような構成の本発明によると、導入壁部を形成している上壁の後端が下壁の後端よりも前方に位置して該下壁に露呈面を形成するので、受入部が後端側で上方に開放されることとなり、上方からの斜め導入が容易かつ目視による導入時の平型導体の位置の確認が可能となる。   According to the present invention having such a configuration, the rear end of the upper wall forming the introduction wall portion is located in front of the rear end of the lower wall and forms an exposed surface on the lower wall. It is opened upward on the rear end side, so that oblique introduction from above is easy and the position of the flat conductor at the time of visual introduction can be confirmed.

また、平型導体の導入開始時、特に斜め導入の際に、端子の接続部が受入部側に配列されてても、露呈面が接続部よりも上方に位置しているので、平型導体の先端縁は接続部に当接することなく確実に露呈面で案内される。さらには、回路基板へのコネクタの実装後、接続部の回路基板との半田接続状態で上方から容易に目視確認が可能となる。   Further, when the introduction of the flat conductor is started, especially when the introduction is performed obliquely, the exposed surface is located above the connection portion even if the terminal connection portion is arranged on the receiving portion side. The leading edge of the is reliably guided on the exposed surface without abutting against the connecting portion. Furthermore, after the connector is mounted on the circuit board, it can be easily visually confirmed from above in the solder connection state with the circuit board at the connection portion.

本発明において、複数の端子は少なくともその一部の端子の接続部が前後方向で導入壁部の範囲内に位置するようにすることができる。
本発明において、導入壁部は、コネクタ幅方向の少なくとも両端側で、上壁の後縁下面に、平型導体を下方に向け受入部の内方へ導入案内するテーパ面が導入上部案内面として設けられていることが好ましい。 In the present invention, at least some of the terminals of the plurality of terminals can be positioned within the range of the introduction wall portion in the front-rear direction.
In the present invention, the introduction wall portion is at least at both ends in the connector width direction, and the tapered surface that introduces and guides the flat conductor to the inside of the receiving portion toward the lower surface of the rear edge of the upper wall serves as the introduction upper guide surface. It is preferable to be provided.

こうすることで、平型導体を斜め導入する際、上壁の導入上部案内面で平型導体を受入部へ向け円滑に導入することができる。   By doing so, when the flat conductor is introduced obliquely, the flat conductor can be smoothly introduced to the receiving portion by the introduction upper guide surface of the upper wall.

本発明において、導入壁部は、側壁の後縁内面に、平型導体の側端縁をコネクタ幅方向で内方へ導入案内するテーパ面が導入側部案内面として設けられていることが好ましい。   In the present invention, it is preferable that the introduction wall portion is provided with a tapered surface as an introduction side portion guide surface on the inner surface of the rear edge of the side wall to introduce and guide the side edge of the flat conductor inward in the connector width direction. .

こうすることで、平型導体の接続部分を受入部へ導入する際、該平型導体を導入側部案内面でコネクタ幅方向で案内し、接続部分を同方向での正規位置へもたらす。   In this way, when the connecting portion of the flat conductor is introduced into the receiving portion, the flat conductor is guided in the connector width direction by the introduction side portion guide surface, and the connecting portion is brought to the normal position in the same direction.

本発明において、導入壁部は、下壁の後端がコネクタ幅方向で端子の接続部の配列域にて前方へ没した没入部を有し、該接続部が上記没入部内で後方に向け露出して突出しているようにすることができ、端子接続部が露呈することで半田接続が容易となる。   In the present invention, the introduction wall portion has an immersion portion in which the rear end of the lower wall is immersed forward in the connector width direction in the arrangement region of the terminal connection portion, and the connection portion is exposed backward in the immersion portion. Thus, the solder connection is facilitated by exposing the terminal connection portion.

本発明は、以上のように、ハウジングの導入壁部における上壁の後端を下壁の後端よりも前方に位置させて開放することとしたので、平型導体の導入、特に斜め導入の場合、導入操作がし易くなると共に目視確認しながら導入位置そして姿勢を定められ、これに加え、露呈面が、端子配列域外にあって、端子の接続部の上縁よりも上方に位置しているので、平型導体の先端縁が下壁の露呈部へ当接して導入案内されるようになり、平型導体の接続部分の受入部への導入の際に、平型導体の先端縁が端子と当接することがなく、傷められることがなくなり、損傷を受けた平型導体の前端での削れに生ずる樹脂粉による接触不良、金属粉によるショートが発生することを防止する。   In the present invention, as described above, since the rear end of the upper wall in the introduction wall portion of the housing is positioned and opened in front of the rear end of the lower wall, the introduction of the flat conductor, particularly the oblique introduction, is performed. In this case, the introduction position and posture can be determined while facilitating the introduction operation and visually confirming, and in addition, the exposed surface is outside the terminal arrangement area and is located above the upper edge of the terminal connection portion. As a result, the leading edge of the flat conductor comes into contact with the exposed portion of the lower wall and is guided to be introduced, and the leading edge of the flat conductor is introduced into the receiving portion of the connecting portion of the flat conductor. It does not come into contact with the terminal and is not damaged, thereby preventing contact failure due to resin powder generated due to scraping at the front end of a damaged flat conductor and short circuit due to metal powder.

The first terminal receiving groove 31, the second terminal receiving groove 32, and the fixing bracket receiving groove 33 are communicated with each other in the terminal arrangement direction (the direction perpendicular to the paper surface in FIGS. 3 and 4) behind the position. A space opened rearward so as to receive the connecting portion F1 of the flat conductor F from the rear is formed as the receiving portion 38. More specifically, a receiving portion 38 is formed inside the rear portion of the peripheral wall formed by the upper wall 35, the lower wall 36, and the side wall 37 of the housing 30 (the rear portion from the position of the connecting portions 14, 19, 23). A wall surrounding the receiving portion 38 forms an introduction wall portion 39.

上記ハウジング３０は、図３（Ａ）〜（Ｃ）そして図４（Ａ）に見られるように、第一端子収容溝３１には第一端子１１の連結部１４よりも前方位置に第一端子１１の係止突起１３Ｂ−３が喰い込んで係止する係止壁４０が形成され、第二端子収容溝３２そして固定金具収容溝３３には、図４（Ｂ），（Ｃ）に見られるように、第二端子１６の連結部１９そして固定金具２０の連結部２３のそれぞれよりも後方位置で係止突起１８Ａ−３が喰い込む係止壁４１そして係止突起２２Ａ−３が喰い込む係止壁４２が設けられていて、それぞれ第一端子１１、第二端子１６そして固定金具２０の抜けの防止を図っている。   As shown in FIGS. 3A to 3C and FIG. 4A, the housing 30 has a first terminal in the first terminal receiving groove 31 at a position ahead of the connecting portion 14 of the first terminal 11. 4B and FIG. 4C are formed in the second terminal receiving groove 32 and the fixing bracket receiving groove 33.

A stop wall 42 is provided to prevent the first terminal 11, the second terminal 16, and the fixture 20 from coming off.

上記導入壁部３９を形成するように上下に対をなして位置する上壁３５と下壁３６のうち、上壁３５はその後端が下壁３６の後端よりも前方に位置していて、換言すれば、下壁３６の後端が上壁３５の後端よりも後方に突出していて、該下壁３６の後方への突出部分の上面で上方に開放された露呈面４３を形成している。本実施形態では、コネクタ幅方向での端子配列範囲で、下壁３６の後端が上壁３５の後端の位置まで前方へ没していて、上記露呈面４３は端子配列範囲に対して両側に形成されている。すなわち下壁３６は、上記端子配列範囲で、没入部４４が形成されている。その結果、下壁３６のハウジング３０の後端にまで延びる第一端子１１の接続部１３Ａ−１は、上記没入部４４内に位置して露出している。該接続部１３Ａ−１は露呈しているので、第一端子１１をハウジングへ圧入する際の確認、接続部１３Ａ−１での半田接続時の半田の確認ができるとともに、半田時にはハウジング面を伝わるフラックス上りを防止できる。このように、下壁３６に上記没入部４４が形成されているので、露呈面４３は、図１（Ａ）に見られるように、上記没入部４４に対してコネクタ幅方向の両側の位置、換言すれば、第一端子１１の接続部１３Ａ−１の配列範囲の両外側に位置している。上記露呈面４３は、本実施形態では、固定金具２０のための固定金具収容溝３３を挟んで二つの領域に区分されていて、コネクタ幅方向で上記固定金具収容溝３３よりも外方に位置する外方露呈面４３Ａと、上記固定金具収容溝３３よりも内方に位置する内方露呈面４３Ｂとを有している。外方露呈面４３Ａは内方露呈面４３Ｂよりも若干高く位置している。図２（Ｂ）からも理解できるように、外方露呈面４３Ａと内方露呈面４３Ｂの間には若干の高低段差があるものの、前後方向で露呈面４３の範囲にあっては、両者とも没入部４４に位置する第一端子１１の接続部１３Ａ−１の上縁よりも上方に位置しており、該接続部１３Ａ−１の上縁に対して、外方露呈面４３Ａはδ１だけ高く、内方露呈面４３Ｂはδ２（＜δ１）だけ高くなっている。   Among the upper wall 35 and the lower wall 36 that are positioned in a pair so as to form the introduction wall portion 39, the upper wall 35 has a rear end positioned forward of a rear end of the lower wall 36, In other words, the rear end of the lower wall 36 projects rearward from the rear end of the upper wall 35, and the exposed surface 43 opened upward is formed on the upper surface of the rearward projecting portion of the lower wall 36. Yes. In this embodiment, the rear end of the lower wall 36 sunk forward to the position of the rear end of the upper wall 35 in the terminal arrangement range in the connector width direction, and the exposed surface 43 is on both sides of the terminal arrangement range. Is formed. That is, the lower wall 36 has an immersion portion 44 in the terminal arrangement range. As a result, the connection portion 13A-1 of the first terminal 11 extending to the rear end of the housing 30 of the lower wall 36 is located and exposed in the immersion portion 44. Since the connection portion 13A-1 is exposed, it is possible to confirm when the first terminal 11 is press-fitted into the housing, to confirm the solder at the time of solder connection at the connection portion 13A-1, and to transmit through the housing surface during soldering. Flux up can be prevented. Thus, since the said immersion part 44 is formed in the lower wall 36, the exposed surface 43 is the position of the both sides of the connector width direction with respect to the said immersion part 44, as seen in FIG. In other words, it is located on both outer sides of the arrangement range of the connection portion 13A-1 of the first terminal 11. In the present embodiment, the exposed surface 43 is divided into two regions across the fixing bracket receiving groove 33 for the fixing bracket 20, and is positioned outward of the fixing bracket receiving groove 33 in the connector width direction. The outer exposure surface 43 </ b> A and the inner exposure surface 43 </ b> B located inward of the fixing bracket receiving groove 33 are provided. The outer exposed surface 43A is located slightly higher than the inner exposed surface 43B. As can be understood from FIG. 2B, although there is a slight level difference between the outer exposed surface 43A and the inner exposed surface 43B, both are within the range of the exposed surface 43 in the front-rear direction. It is located above the upper edge of the connecting portion 13A-1 of the first terminal 11 located in the immersion portion 44, and the outer exposed surface 43A is higher by δ1 than the upper edge of the connecting portion 13A-1. The inner exposed surface 43B is higher by δ2 (<δ1).

外方露呈面４３Ａは、平型導体Ｆの受入部３８への導入時、特に斜め導入時に該平型導体Ｆの前端縁が当接して平型導体Ｆを案内するとともに、平型導体Ｆの前端が第一端子１１の接続部１３Ａ−１の上縁と当接・衝突することを防止する。   The outer exposed surface 43A guides the flat conductor F by the front edge of the flat conductor F coming into contact with the flat conductor F when the flat conductor F is introduced into the receiving portion 38, particularly when obliquely introduced. The front end is prevented from abutting and colliding with the upper edge of the connection portion 13A-1 of the first terminal 11.

外方露呈面４３Ａよりも若干低い内方露呈面４３Ｂは、平型導体Ｆが導入された後、可動部材３の閉位置への回動時に、第一端子１１の接触部１２Ａ−１そして第二端子１６の接触部１７Ａ−１により下方へ圧せられた際、該平型導体Ｆの撓みを許容するとともに該平型導体Ｆの下面を支える機能を有している。   The inner exposure surface 43B, which is slightly lower than the outer exposure surface 43A, has the contact portion 12A-1 and the first terminal 11 of the first terminal 11 when the movable member 3 is rotated to the closed position after the flat conductor F is introduced. When pressed downward by the contact portion 17A-1 of the two terminals 16, it has a function of allowing the flat conductor F to bend and supporting the lower surface of the flat conductor F.

上記露呈面４３は、前後方向で上記接続部１３Ａ−１と範囲を重複しているので、コネクタを前後方向で大型化することなく該露呈面４３を設けることができる。   Since the exposed surface 43 overlaps with the connecting portion 13A-1 in the front-rear direction, the exposed surface 43 can be provided without increasing the size of the connector in the front-rear direction.

上記下壁３６に対向する上壁３５は、既述のように、その後端が下壁３６の後端よりも前方に位置しており、図２（Ａ），（Ｂ）に見られるように、該上壁３５の後縁下面が受入部３８へ平型導体Ｆを導入しやすく案内するための導入上部案内面４５がテーパ面で形成されている。該導入上部案内面４５は、第一端子収容溝３１そして第二端子収容溝３２の位置では、中断して不存在となっているが、上記受入部３８の全幅域、すなわち両側の側壁３７の間にわたり形成されている。   As described above, the upper wall 35 facing the lower wall 36 has a rear end positioned forward of the rear end of the lower wall 36, as shown in FIGS. 2 (A) and 2 (B).

The introduction upper guide surface 45 is interrupted and does not exist at the positions of the first terminal receiving groove 31 and the second terminal receiving groove 32, but the entire width region of the receiving portion 38, that is, the side wall 37 on both sides. It is formed across.

側壁３７には、上壁３５の後端よりも後方範囲で、コネクタ幅方向での内側面に平型導体Ｆをコネクタ幅方向で内方に向け正規位置へ案内する導入側部案内面４６が形成されている。該導入側部案内面４６は、図２（Ａ），（Ｂ）に見られるように、外方露呈面４３Ａの外側縁に隣接する導入側部横案内面４６Ａと、該導入側部横案内面４６Ａの前端縁から垂立する導入側部縦案内面４６Ｂとを有している。すなわち、導入側部横案内面４６Ａが下壁３６の後端の位置から上壁３５の後端の位置まで及んでおり、導入側部縦案内面４６Ｂは、上壁３５の後端に形成されている。したがって、平型導体Ｆは、幅方向にずれて導入される際には、上記導入側部横案内面４６Ａで正規位置へ向け案内された後、次いで導入側部縦案内面４６Ｂで案内される。   The side wall 37 has an introduction side guide surface 46 for guiding the flat conductor F inward in the connector width direction to the normal position on the inner side surface in the connector width direction in the rearward range from the rear end of the upper wall 35. Is formed. As shown in FIGS. 2 (A) and 2 (B), the introduction side portion guide surface 46 includes an introduction side portion side guide surface 46A adjacent to the outer edge of the outer exposure surface 43A, and the introduction side portion side guide. And an introduction side vertical guide surface 46B that hangs from the front edge of the surface 46A. That is, the introduction side lateral guide surface 46A extends from the rear end position of the lower wall 36 to the rear end position of the upper wall 35, and the introduction side vertical guide surface 46B is formed at the rear end of the upper wall 35. ing. Therefore, when the flat conductor F is introduced shifted in the width direction, it is guided toward the normal position by the introduction side lateral guide surface 46A and then guided by the introduction side vertical guide surface 46B. .

このように後部で導入壁部３９を形成するハウジング３０は、図１、図３、図４に見られるように、前部で可動部材３を支持し該可動部材３の回転を許容するために、前方そして上方に開放されて切欠部４７が端子配列範囲にわたり形成されており、上壁３５には、該切欠部４７の幅方向縁部４７Ａから、第一端子１１の可撓腕部１２Ｂそして第二端子１６の可撓腕部１７Ｂを収める溝切欠部４８Ａ，４８Ｂがそれぞれ後方に向け延びて形成され、また、固定金具２０の上腕部２１を収容する溝切欠部４８Ｃが上記溝切欠部４８Ａ，４８Ｂよりも長く後方に向け延びて形成されている。   Thus, the housing 30 forming the introduction wall portion 39 at the rear portion supports the movable member 3 at the front portion and allows rotation of the movable member 3 as seen in FIGS. 1, 3, and 4. A notch 47 is opened to the front and upward, and is formed over the terminal arrangement range. The upper wall 35 has a flexible arm 12B of the first terminal 11 from the width direction edge 47A of the notch 47, and Groove notches 48A and 48B for accommodating the flexible arm portion 17B of the second terminal 16 are formed extending rearward, respectively, and a groove notch 48C for accommodating the upper arm portion 21 of the fixing bracket 20 is formed in the groove notch 48A. , 48B and extending rearward.

The first terminal cam portion 54 and the second terminal cam portion 55 are located above the cam support arm portion 13B of the first terminal 11 and the cam support arm portion 18B of the second terminal 16 when the movable member 3 is rotated. When the movable member 3 comes to the closed position while being pivotally supported by the edge, the upper edge of the first terminal cam portion 54 presses the pressure receiving portion 12B-1 of the first terminal 11 upward, and the second terminal cam The upper edge of the portion 55 presses the pressure receiving portion 17B-1 of the second terminal 16 upward. When the pressure receiving portions 12B-1 and 17B-1 are pressed, the flexible arm portion 12B of the first terminal 11 and the flexible arm portion 17B of the second terminal 16 bend upward, respectively, and the first terminal is based on the principle of leverage. 11 contact arm portions 12A and second terminal 16 contact arm portions 17A are bent downward. As a result, the contact portion 12A-1 of the first terminal 11 and the contact portion 17A-1 of the second terminal 16 are brought into contact with the corresponding pads F2B-1 and F2A-1 of the circuit board F.

固定金具用カム部５６は、図４（Ｃ）に見られるように、円形をなしていて、固定金具２０の下腕部２２の前部をなす接続腕部２２Ｂには支持されておらず、可動部材３が閉位置にきたときに、該固定金具用カム部５６が上方へ移動して固定金具２０の受圧部２１Ｂ−１を上方へ押圧する。受圧部２１Ｂ−１が上方へ押圧されると、第一端子１１そして第二端子１６と同じ原理で、後端に設けられた爪状の係止部２１Ａ−１が下方へ撓み変位して、平型導体Ｆの係止凹部Ｆ３に進入し、上記係止部２１Ａ−１により平型導体Ｆの抜けが防止される。   As shown in FIG. 4C, the fixing bracket cam portion 56 has a circular shape and is not supported by the connection arm portion 22B that forms the front portion of the lower arm portion 22 of the fixing bracket 20, When the movable member 3 comes to the closed position, the fixing bracket cam portion 56 moves upward to press the pressure receiving portion 21B-1 of the fixing bracket 20 upward. When the pressure receiving portion 21B-1 is pressed upward, the claw-like locking portion 21A-1 provided at the rear end is bent downward and displaced by the same principle as the first terminal 11 and the second terminal 16. The flat conductor F enters the locking recess F3, and the locking portion 21A-1 prevents the flat conductor F from coming off.

次に、このような構成の本実施形態のコネクタへの平型導体Ｆの接続要領について説明する。   Next, the connection procedure of the flat conductor F to the connector of this embodiment having such a configuration will be described.

平型導体Ｆのコネクタへの接続に先立ち、コネクタの可動部材３を、図１（Ａ）そして図３（Ａ）〜（Ｃ）に見られるように、起立させて開位置にもたらす。第一端子１１、第二端子１６、固定金具２０は、可動部材３の第一端子用カム部５４、第二端子用カム部５５、固定金具用カム部５６から何ら力を受けていないので、第一端子１１の接触腕部１２Ａ、第二端子１６の接触腕部１７Ａ、固定金具２０の係止腕部２１Ａは、下方へ撓み変位しておらず、自由状態にあり、平型導体Ｆが受入部３８へ容易に導入可能となっている。   Prior to connecting the flat conductor F to the connector, the movable member 3 of the connector is raised to the open position as seen in FIG. 1 (A) and FIGS. 3 (A)-(C). Since the first terminal 11, the second terminal 16, and the fixing bracket 20 are not receiving any force from the first terminal cam portion 54, the second terminal cam portion 55, or the fixing bracket cam portion 56 of the movable member 3, The contact arm portion 12A of the first terminal 11, the contact arm portion 17A of the second terminal 16, and the locking arm portion 21A of the fixing bracket 20 are not deflected downward and are in a free state, and the flat conductor F is It can be easily introduced into the receiving unit 38.

平型導体Ｆは、コネクタへの導入位置（上下及び横方向位置）が正規位置にあり、導入方向が回路基板と平行な水平方向に行われる場合には、何の問題もなく、平型導体Ｆの接続部分Ｆ１は上記受入部３８内へ導入される。   The flat conductor F has no problem when the introduction position to the connector (vertical and lateral positions) is a normal position and the introduction direction is performed in a horizontal direction parallel to the circuit board. The connecting portion F1 of F is introduced into the receiving portion 38.

平型導体Ｆが正規位置からずれていたり、斜めに導入されることが往々にしてあり、かかる場合、導入が円滑に行えなかったり、平型導体の先端縁が端子に衝突して損傷を受けたりする傾向にあるが、本実施形態のコネクタでは、これに対処している。   In many cases, the flat conductor F is shifted from the normal position or introduced obliquely. In such a case, the introduction cannot be performed smoothly, or the leading edge of the flat conductor collides with the terminal and is damaged. However, the connector of this embodiment deals with this.

図３（Ａ）〜（Ｃ）に見られるごとく、平型導体Ｆが斜めに導入されようとすると、本実施形態では、平型導体の幅方向両端に対応して位置する下壁３６の露呈面４３（外方露呈面４３Ａ）が第一端子１１の接続部１３Ａ−１の上縁よりも上方に位置しているので、平型導体Ｆの前端縁が上記第一端子１１の接続部１３Ａ−１の上縁に衝突あるいは当接することなく上記露呈面４３に当接して、受入部３８へ向け前方へ案内される。したがって、平型導体Ｆはその前端縁が金属製である第一端子１１によって損傷を受けることなく、上記露呈面４３を滑りながら円滑に受入部３８へ導入される。   As seen in FIGS. 3A to 3C, when the flat conductor F is introduced obliquely, in this embodiment, the exposure of the lower wall 36 positioned corresponding to both ends in the width direction of the flat conductor is exposed. Since the surface 43 (outside exposure surface 43A) is located above the upper edge of the connection portion 13A-1 of the first terminal 11, the front end edge of the flat conductor F is the connection portion 13A of the first terminal 11. -1 abuts on the exposed surface 43 without colliding with or abutting on the upper edge, and is guided forward toward the receiving portion 38. Therefore, the flat conductor F is smoothly introduced into the receiving portion 38 while sliding on the exposed surface 43 without being damaged by the first terminal 11 whose front end edge is made of metal.

次に、平型導体Ｆが回路基板に対して平行あるいは斜めに導入される際に、導入位置が上下あるいはコネクタ幅方向にずれている場合がある。かかる場合、平型導体Ｆは、その前端縁あるいは前端部が導入上部案内面４５に当接して受入部３８へ向け下方に案内され、導入側部案内面４６、すなわち導入側部縦案内面４６Ａそして導入側部横案内面４６Ｂによりコネクタ幅方向で正規位置へ向け案内される。   Next, when the flat conductor F is introduced in parallel or obliquely with respect to the circuit board, the introduction position may be shifted vertically or in the connector width direction. In this case, the front end edge or front end portion of the flat conductor F abuts on the introduction upper guide surface 45 and is guided downward toward the receiving portion 38, and the introduction side portion guide surface 46, that is, the introduction side portion vertical guide surface 46A. And it is guided toward the normal position in the connector width direction by the introduction side portion lateral guide surface 46B.

かくして、平型導体Ｆはその接続部分Ｆ１が受入部３８内の正規位置へそして正規導入深さ位置まで導入される（図１（Ｂ）参照）。   Thus, the connecting portion F1 of the flat conductor F is introduced to the normal position in the receiving portion 38 and to the normal introduction depth position (see FIG. 1B).

次に、可動部材３を図１（Ｂ）の開位置から図４（Ａ）〜（Ｃ）に見られる閉位置へ回動する。可動部材３が閉位置へもたらされると、既述したように、第一端子１１と第二端子１６はそれらの受圧部１２Ｂ−１，１７Ｂ−１で対応する第一端子用カム部５４、第二端子用カム部５５で上方へ押圧されて可撓腕部１２Ｂ，１７Ｂが上方に撓む結果、接触腕部１２Ａ，１７Ａが下向きに撓み、接触部１２Ａ−１，１７Ａ−１が対応パッドＦ２Ｂ−１，Ｆ２Ａ−１に接触するとともに平型導体Ｆを下方へ圧し、接圧を高める。一方、固定金具２０は、受圧部２１Ｂ−１が固定金具用カム部５６で上方へ押圧され、第一端子１１、第二端子１６の場合と同様の原理で、爪状の係止部２１Ａ−１が下方へ移動変位して平型導体Ｆの係止凹部Ｆ３へ進入し、平型導体Ｆの抜けが確実に防止される。   Next, the movable member 3 is rotated from the open position in FIG. 1 (B) to the closed position seen in FIGS. 4 (A) to 4 (C). When the movable member 3 is brought to the closed position, as described above, the first terminal 11 and the second terminal 16 correspond to the first terminal cam portion 54, the second terminal 16 and the first terminal cam portion 54B. As a result of pressing upward by the two-terminal cam portion 55 and bending the flexible arm portions 12B and 17B upward, the contact arm portions 12A and 17A bend downward, and the contact portions 12A-1 and 17A-1 correspond to the corresponding pads F2B. -1 and F2A-1, and the flat conductor F is pressed downward to increase the contact pressure. On the other hand, in the fixing bracket 20, the pressure receiving portion 21B-1 is pressed upward by the fixing bracket cam portion 56, and the claw-shaped locking portion 21A- is operated on the same principle as the first terminal 11 and the second terminal 16. 1 moves downward and enters into the locking recess F3 of the flat conductor F, and the flat conductor F is reliably prevented from coming off.

本実施形態では、既述したように、平型導体Ｆにはその接続部分Ｆ１に補強パッドＦ４が設けられている。図１（Ａ）に見られるように、該補強パッドＦ４の後縁は平型導体Ｆの係止凹部Ｆ３の直後方に位置しており、前後方向で、二種のパッドＦ２Ａ，Ｆ２Ｂのうちの後方に位置するパッドＦ２Ｂ−１の後端に近い位置にあり、平型導体Ｆの接続部分Ｆ１が正規位置まで受入部３８内へ導入されたときには、図１（Ｂ）に見られるように、上記補強パッドＦ４の後縁はハウジング３０の上壁３５の後端と同じ位置にくる。すなわち、平型導体Ｆが正規位置まで完全に導入されたときには、上記補強パッドＦ４は、上壁３５に覆われてちょうど見えなくなる。上記補強パッドＦ４は、回路線Ｆ２のパッドと同じく金属製で光沢があり、平型導体Ｆが正規位置に到達するまでの導入過程で光っているので目視し易い。その後、平型導体Ｆが正規位置まで達すると、この光っていた補強パッドＦ４が上壁３５に覆われて急に見えなくなるので、正規位置までの導入されたことをきわめて容易に確認できる。   In the present embodiment, as described above, the flat conductor F is provided with the reinforcing pad F4 at the connection portion F1. As shown in FIG. 1A, the rear edge of the reinforcing pad F4 is located immediately behind the locking recess F3 of the flat conductor F, and in the front-rear direction, of the two types of pads F2A and F2B. As shown in FIG. 1B, when the connection portion F1 of the flat conductor F is introduced into the receiving portion 38 to the normal position, the pad F2B-1 is located at the rear end of the pad F2B-1. The rear edge of the reinforcing pad F4 is located at the same position as the rear end of the upper wall 35 of the housing 30. That is, when the flat conductor F is completely introduced to the normal position, the reinforcing pad F4 is covered with the upper wall 35 and cannot be seen. The reinforcing pad F4 is made of metal and is glossy like the pad of the circuit line F2, and is easily visible since it shines in the introduction process until the flat conductor F reaches the normal position. Thereafter, when the flat conductor F reaches the normal position, the shining reinforcing pad F4 is covered with the upper wall 35 and suddenly disappears, so it can be confirmed very easily that the flat conductor F has been introduced to the normal position.

次に、平型導体Ｆが不完全導入位置にあるときには、図５（Ａ）のように、補強パッドＦ４（図５（Ａ）では理解しやすいように補強パッドの域に点を分布させ付してある）の後部分が上壁３５の後縁からはみ出しており、これを目視することで不完全導入を発見できる。これは、上壁３５の後端が下壁３６の後端よりも前方に没していることにより可能となった。   Next, when the flat conductor F is at the incomplete introduction position, as shown in FIG. 5 (A), the points are distributed over the reinforcing pad F4 (in FIG. 5 (A), the points are distributed in the reinforcing pad area for easy understanding). The rear portion protrudes from the rear edge of the upper wall 35, and incomplete introduction can be found by visual observation. This is possible because the rear end of the upper wall 35 is submerged in front of the rear end of the lower wall 36.

次に、補強パッドＦ４を図１（Ａ）そして図５（Ａ）のように、平型導体Ｆが正規位置まで完全に導入されたときに上壁３５で覆われ、不完全導入のときに後方にはみ出して外部から見えるようにしなくとも、他のパターン形式として、図５（Ｂ）のように、正規位置まで導入されたときに上壁３５の後端の位置となる位置から後方部分に補強パッドＦ４の目視確認部分Ｆ４−１を形成して、不完全導入の場合には、該目視確認部分Ｆ４−１の前縁が上壁３５の後端にまで達していないことで、不完全導入を目視確認できる。   Next, as shown in FIGS. 1A and 5A, the reinforcing pad F4 is covered with the upper wall 35 when the flat conductor F is completely introduced to the normal position, and when it is incompletely introduced. Even if it does not protrude to the outside and can be seen from the outside, as another pattern format, as shown in FIG. When the visual confirmation part F4-1 of the reinforcing pad F4 is formed and incompletely introduced, the front edge of the visual confirmation part F4-1 does not reach the rear end of the upper wall 35. The introduction can be confirmed visually.

次に、導入壁部３９に形成される平型導体の案内面についての他の形態を説明する。   Next, another embodiment of the guide surface of the flat conductor formed on the introduction wall portion 39 will be described.

図２（Ａ），（Ｂ）の形態の、導入側部案内面４６では、導入側部横案内面４６Ａの前端位置に導入側部縦案内面４６Ｂが、設けられていたが、図６（Ａ），（Ｂ）の例では、下壁３６の上面からコネクタ幅方向内側に向け下方へ傾く横テーパ面の導入側部横案内面４６Ａと、露呈面４３に対して垂立し下壁３６の後端面からコネクタ幅方向内側に向け前方へ傾く縦テーパ面の導入側部縦案内面４６Ｂとを有している。上記導入側部横案内面４６Ａと導入側部縦案内面４６Ｂは、入口側となる下壁３６の後端寄りの位置で凸角部を形成し、互いに交差する稜線４６Ｃを共有している。したがって、平型導体Ｆは、幅方向にずれて導入される際には、上記導入側部縦案内面４６Ａもしくは、導入側部横案内面４６Ｂで正規位置へ向け案内される。   2 (A) and 2 (B), the introduction side portion guide surface 46 is provided with the introduction side portion vertical guide surface 46B at the front end position of the introduction side portion lateral guide surface 46A. In the examples of A) and (B), the lower wall 36 is vertically suspended from the lateral side guide surface 46A of the laterally tapered surface inclined downward from the upper surface of the lower wall 36 toward the inner side in the connector width direction and the exposed surface 43. And an introduction side vertical guide surface 46B of a vertical taper surface inclined forward from the rear end surface toward the inner side in the connector width direction. The introduction side lateral guide surface 46A and the introduction side vertical guide surface 46B form a convex corner at a position near the rear end of the lower wall 36 on the entrance side, and share a ridge line 46C intersecting each other. Therefore, when the flat conductor F is introduced while being shifted in the width direction, it is guided toward the normal position by the introduction side portion vertical guide surface 46A or the introduction side portion lateral guide surface 46B.
