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.

平型導体用電気コネクタとしては、例えば、特許文献１に開示されている電気コネクタが知られている。この特許文献１にあっては、平型導体（フレキシブルケーブル）が接続される端子は金属板の平坦な板面を維持した形態に作られており、並んで上下に位置する支持部として一つの上腕部と接点部として可撓性のある一つの下腕部とをそれらの一端側を自由端とする形態として連結部で連結して一部材として形成し、端子を保持するハウジングの受入部から上記上腕部と下腕部の自由端同士間へ平型導体の先端部に形成された接続部分を挿入するようになっている。   As the flat conductor electrical connector, for example, an electrical connector disclosed in Patent Document 1 is known. In this Patent Document 1, a terminal to which a flat conductor (flexible cable) is connected is made in a form that maintains a flat plate surface of a metal plate, and one terminal is used as a support portion positioned vertically. From the receiving portion of the housing that holds the terminal, the upper arm portion and one flexible lower arm portion as a contact portion are connected to each other by a connecting portion in a form having one end side as a free end. A connecting portion formed at the distal end portion of the flat conductor is inserted between the free ends of the upper arm portion and the lower arm portion.

上腕部には可動部材としてアクチュエータを回動可能に支持する凹状の案内支持部が形成されており、下腕部には平型導体との接触のための接触部としての接触突起が設けられていて、上記可動部材の回動操作を行うことで、平型導体を下腕部の接触部へ圧して、接圧をもって該接触部との電気的接続を確保している。上記下腕部は一つの腕状部分を成して形成されているが、その上縁に位置する接触部は、該下腕部の長手方向で、複数箇所に形成されている。   The upper arm portion is provided with a concave guide support portion that rotatably supports the actuator as a movable member, and the lower arm portion is provided with a contact protrusion as a contact portion for contact with the flat conductor. Thus, by rotating the movable member, the flat conductor is pressed against the contact portion of the lower arm portion, and electrical connection with the contact portion is ensured with contact pressure. The lower arm portion is formed as one arm-shaped portion, and contact portions located at the upper edge thereof are formed at a plurality of locations in the longitudinal direction of the lower arm portion.

特許文献１によると、かかるコネクタにあっては、下腕部に複数の接触部を設けたので、接触部に異物が付着しあるいは接触部の表面が酸化した事態においても、少なくとも他の接触部がこれらの事態による影響の回避のもとで平型導体との接触を確保できるとしている。   According to Patent Document 1, in such a connector, since a plurality of contact portions are provided in the lower arm portion, at least other contact portions even in a situation where foreign matter adheres to the contact portions or the surface of the contact portions is oxidized. However, it is said that the contact with the flat conductor can be ensured while avoiding the influence of these situations.

特開２００７−０１２６１８JP2007-012618

しかしながら、特許文献１のコネクタにあっては、端子は一つの下腕部に前後して位置する複数の接触部を設けることとしたので、下腕部が疲労により可撓性の低下を生じたり、複数の接触部のうちの一つにでも異物が付着したりすると、接触部と平型導体との間で接触不具をもたらすという虞れがあった。   However, in the connector disclosed in Patent Document 1, since the terminal is provided with a plurality of contact portions positioned on the front and back of one lower arm portion, the lower arm portion may be less flexible due to fatigue. If foreign matter adheres to any one of the plurality of contact portions, there is a possibility that a contact failure is caused between the contact portion and the flat conductor.

下腕部は一つしか設けられていないので、この下腕部が疲労して可撓性が低下すると、複数の接触部のすべてにおいて適切な接圧を確保できなくなるし、一つの接触部に異物が付着したときに、異物が、接触部と平型導体との間に噛み込まれた状態を生じて、上記一つの接触部を平型導体から引き離す方向に変位させるように作用すると、他の接触部も追従して同様に平型導体から離れる方向に変位してしまうこととなり、すべての接触部で接圧が低下する。その結果として、端子はその接触部と平型導体との間で接触不具合をもたらすこととなる。   Since only one lower arm portion is provided, if this lower arm portion is fatigued and its flexibility is lowered, it becomes impossible to secure an appropriate contact pressure in all of the plurality of contact portions. When a foreign object adheres, the foreign object is caught between the contact part and the flat conductor, and the one contact part is displaced in the direction away from the flat conductor. Similarly, the contact portion is also displaced in a direction away from the flat conductor, and the contact pressure is reduced at all contact portions. As a result, the terminal causes a contact failure between the contact portion and the flat conductor.

本発明は、かかる不具合を解消できる端子を有す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。   This invention makes it a subject to provide the electrical connector for flat type conductors which has a terminal which can eliminate this malfunction.

本発明に係る平型導体用電気コネクタは、金属板の平坦な板面に沿って弾性腕部が延びるように設けられた端子が上記板面に対し直角方向を配列方向としてハウジングにより保持されており、該ハウジングは上記弾性腕部の自由端上へ平型導体の接続部分を挿入することを許容する空間を形成する受入部を有し、ハウジングと端子の少なくとも一方により移動可能に支持されている可動部材を移動操作することで、上記弾性腕部と平型導体の接続部分を接圧のもとに接触させて電気的に接続する。   The flat conductor electrical connector according to the present invention is such that terminals provided such that the elastic arm portion extends along the flat plate surface of the metal plate are held by the housing with the direction perpendicular to the plate surface as the arrangement direction. The housing has a receiving portion that forms a space that allows the connecting portion of the flat conductor to be inserted on the free end of the elastic arm portion, and is movably supported by at least one of the housing and the terminal. By moving the movable member, the connecting portion of the elastic arm portion and the flat conductor is brought into contact with each other under a contact pressure to be electrically connected.

かかる平型導体用電気コネクタにおいて、本発明では、端子は、金属板を折り曲げる折曲部を介して上記弾性腕部に並列に形成された他の弾性腕部を有し、それぞれの弾性腕部は独立して撓み変位が可能であると共に、自由端側に平型導体の接続部分との接触のための接触部を有し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 terminal has other elastic arm portions formed in parallel to the elastic arm portions via bent portions that bend the metal plate, and each elastic arm portion. Is characterized in that it can be flexibly displaced independently and has a contact portion for contact with the connecting portion of the flat conductor on the free end side.

このように構成される本発明のコネクタにあっては、端子の弾性腕部に設けられている接触部上に平型導体の接続部分を挿入配置した後に、可動部材の操作によって平型導体を圧して、平型導体の接続部分と端子の接触部の間で接圧をもって接触接続を行う。   In the connector of the present invention configured as described above, after the flat conductor connecting portion is inserted and arranged on the contact portion provided on the elastic arm portion of the terminal, the flat conductor is operated by operating the movable member. The contact connection is performed with contact pressure between the connection portion of the flat conductor and the contact portion of the terminal.

上記端子には、折曲部を介して並列に複数の弾性腕部が設けられており、これらの複数の弾性腕部のそれぞれが独立して撓み変位可能となっているので、一つの弾性腕部に疲労による撓み特性低下、接触部への異物の付着等の不具合が生じても、不具合のある弾性腕部に係りなく、独立した他の弾性腕部が正規作動して、接触圧が該他の弾性腕部で維持されるし、また接触信頼性も確保される。また、不具合が生じていないときには、複数の弾性腕部にそれぞれ設けられているので、複数箇所の接触部により、さらなる接触信頼性の向上そして接触部が位置する接触点分布範囲を広げて、平型導体の局部的撓み変形の防止を図れる。   The terminal is provided with a plurality of elastic arm portions in parallel via the bent portion, and each of the plurality of elastic arm portions can be flexed and displaced independently. Even if a defect such as deterioration of the bending characteristics due to fatigue or adhesion of a foreign object to the contact part occurs, the independent elastic arm part operates normally regardless of the defective elastic arm part, and the contact pressure is It is maintained by other elastic arms, and contact reliability is also ensured. In addition, when there is no malfunction, each of the elastic arms is provided with a plurality of elastic arms, so that the contact reliability at a plurality of locations can be further improved and the contact point distribution range where the contacts are located can be expanded. The local bending deformation of the mold conductor can be prevented.

本発明において、端子は平型導体のための受入空間を挟み並んで延びる上腕部と下腕部とを有し、該上腕部と下腕部とが互いにそれらの長手方向一端側を自由端として中間位置あるいは他端側で連結部により連結されて一部材をなして上記板面に対し直角方向を配列方向としてハウジングにより保持されており、該ハウジングの受入部は上記上腕部と下腕部の自由端同士間へ平型導体の接続部分を挿入することを許容する上記受入空間を形成し、上記上腕部と下腕部の少なくとも一方が弾性腕部として形成されていて、可動部材を移動操作することで、上記上腕部と下腕部の自由端同士を近接方向に撓み変位させて平型導体の接続部分を挟圧接触するようになっており、複数の弾性腕部は連結部寄りの長手方向位置に形成された折曲部から自由端に向け延びていて、複数の弾性腕部は互いに非接触で独立して撓み変位が可能であると共に、互いの自由端に接触部を有しているようにすることができる。   In the present invention, the terminal has an upper arm portion and a lower arm portion that extend side by side across a receiving space for a flat conductor, and the upper arm portion and the lower arm portion have one end in the longitudinal direction thereof as a free end. It is connected by a connecting portion at an intermediate position or the other end side to form a single member, and is held by the housing with the direction perpendicular to the plate surface as the arrangement direction. The receiving portion of the housing is the upper arm portion and the lower arm portion. The receiving space allowing the insertion of the flat conductor connecting portion between the free ends is formed, and at least one of the upper arm portion and the lower arm portion is formed as an elastic arm portion, and the movable member is moved and operated. By doing so, the free ends of the upper arm portion and the lower arm portion are deflected and displaced in the proximity direction so that the connecting portion of the flat conductor is clamped and contacted, and the plurality of elastic arm portions are closer to the connecting portion. From the bent part formed at the longitudinal position. Extend toward the end, a plurality of resilient arms with is capable of independently deflection displacement without contact with each other, it can be made to have a contact portion to the free end of each other.

こうすることで、本発明は、弾性腕部の接触部上に平型導体を配して可動部材でこれを圧する形式の端子のみならず、平型導体を上腕部と下腕部との両腕部で挟んで、少なくとも一方の腕部を弾性腕部として、可動部材により平型導体を弾性腕部の接触部へ圧するようにする形式にも適用できるようになる。この二つの腕部を有する端子は、受入空間が位置する一端側に可動部材が位置する、いわゆるフロントフリップと称されるものと、上腕部が連結部より他端側にも延びていて可動部材がこの他端側に配されていて、可動部材でこの上腕部の他端部をもち上げ、連結部を支点とした梃子の原理で上腕部の一端側を下方へ弾性変位させて、平型導体を圧する、いわゆるバックフリップと称されるものとが存在しているが、両者のいずれにも適用可能である。   In this way, the present invention is not limited to a terminal of a type in which a flat conductor is disposed on the contact portion of the elastic arm portion and pressed by the movable member, and the flat conductor is connected to both the upper arm portion and the lower arm portion. The present invention can also be applied to a type in which at least one arm portion is sandwiched between the arm portions, and the flat conductor is pressed against the contact portion of the elastic arm portion by a movable member. The terminal having the two arm portions is a so-called front flip in which the movable member is located on one end side where the receiving space is located, and the movable member having the upper arm portion extending from the connecting portion to the other end side. Is arranged on the other end side, lifts the other end portion of the upper arm portion with a movable member, and elastically displaces one end side of the upper arm portion downward with the principle of a lever using the connecting portion as a fulcrum, There is a so-called back flip that presses the conductor, but it can be applied to both.

このように、端子が上腕部と下腕部を有し、少なくとも一方が折曲部を介して並んで形成された主腕部と副腕部を有し、折曲部が連結部寄り位置に位置していると主腕部も副腕部も上記折曲部から先端である自由端に向け延びる片持ち梁状をなすようになり、両腕部の互いの自由端側が独立して撓み変位可能となり、撓み可能な腕長（連結部寄り位置から自由端までの距離）が十分に長くなり撓みやすくなる。   Thus, the terminal has an upper arm portion and a lower arm portion, at least one has a main arm portion and a sub arm portion formed side by side via the bent portion, and the bent portion is located closer to the connecting portion. When positioned, both the main arm part and the sub arm part form a cantilever shape extending from the bent part toward the free end, which is the tip, and the free end sides of both arm parts are flexibly displaced independently. It becomes possible, and the length of the arm that can be bent (distance from the position close to the connecting portion to the free end) becomes sufficiently long and is easily bent.

本発明において、複数の弾性腕部のそれぞれの接触部同士が長手方向で互いにずれて位置しているようにすることが好ましい。こうすることで、接触部同士間で長手方向に間隔が保たれるので、一つの弾性腕部の接触部に異物が付着しても、異物は、他の弾性腕部の接触部にまで及ばずにこの他の弾性腕部の接触部での接触信頼性に悪影響をもたらさない。また、上記長手方向で複数の接触部が存在することとなるので、平型導体は複数の接触部との接触点分布範囲が広くなり、その平型導体の面形態の局部的な崩れを抑制する。 In the present invention, it is preferable that the contact portions of the plurality of elastic arm portions are shifted from each other in the longitudinal direction. In this way, since the distance between the contact portions is maintained in the longitudinal direction, even if a foreign matter adheres to the contact portion of one elastic arm portion, the foreign matter reaches the contact portion of the other elastic arm portion. no Is al have an adverse effect on the contact reliability of the contact portion of the other elastic arm portion without. In addition, since there are a plurality of contact portions in the longitudinal direction, the flat conductor has a wide contact point distribution range with the plurality of contact portions, and suppresses local collapse of the surface form of the flat conductor. To do.

本発明において、端子は、上腕部と下腕部のいずれか一方が可動部材を案内しながら支持する案内支持部を有し、他方が接触部を有しているようにすると、いわゆる既述のフロントフリップそしてバックフリップのいずれの形式にも採用可能な端子となる。その場合、上腕部と下腕部のうち、上記一方が可動部材を支持する支持強度の確保のために他方よりも剛性を高く、換言すれば他方が平型導体との接触信頼性の確保のために撓みやすくなっていることが望ましい。   In the present invention, if the terminal has a guide support portion that supports one of the upper arm portion and the lower arm portion while guiding the movable member, and the other has a contact portion, the so-called terminal is described. This terminal can be used for both front flip and back flip types. In that case, of the upper arm portion and the lower arm portion, the above-mentioned one has higher rigidity than the other in order to secure the supporting strength for supporting the movable member, in other words, the other ensures the contact reliability with the flat conductor. Therefore, it is desirable that it bends easily.

本発明において、端子は、複数の弾性腕部が折曲部形成前の板面に位置する主弾性腕部と、折曲部形成後に該板面から折曲部にて折り曲げられていて上記主弾性腕部と並列をなす位置に形成された副弾性腕部とで形成されている形態とすることができる。 In the present invention, the terminal is a main elastic arm portion in which a plurality of resilient arm portion is located on the plate surface of the front bent portion formed, have been found bent at the bent portion from the plate surface after bending portion forming the It can be set as the form formed with the subelastic arm part formed in the position which makes a parallel with the main elastic arm part.

本発明において、端子は連結部に対して自由端とは反対側で該連結部からハウジング外に延びている接続部を有し、該接続部は、連結部との間の位置で副弾性腕部の方向に偏倚しており、かつ接触部が設けられているいずれかの隣接した並列な弾性腕部の板面同士の中間に位置しているようにすることができる。端子の接続部は、回路基板に形成されたパッドへの半田接続のための部位をなすものであり、上述のように接続部が偏倚していることで、標準的に定まっているパッドの位置を何ら変更せずに接続部の方でパッドに一致した位置をとることができる。また、コネクタの設計上で接続部の位置に対する何らかの要請があれば、これに対応することもできる。 In the present invention, the terminal has a connecting portion extending from the connecting portion to the outside of the housing on the side opposite to the free end with respect to the connecting portion, and the connecting portion is located at a position between the connecting portion and the secondary elastic arm. It can be made to be located in the middle of the plate surfaces of any adjacent parallel elastic arm portions that are biased in the direction of the portion and that are provided with the contact portion. Connecting portions of the terminals, which constitute sites for solder connection to pads formed on the circuit board, by connecting portions as described above is offset, the position of the pad that are definite standard The position corresponding to the pad can be taken at the connecting portion without changing any of the above. In addition, if there is any request for the position of the connecting portion in the design of the connector, this can be dealt with.

本発明は以上のように、端子に設けられた弾性腕部を複数並列に形成して、それぞれの弾性腕部が互いに独立して撓み変位可能なそれらの自由端側に接触部を有することとしたので、一つの弾性腕部で疲労により撓み特性が低下しても、独立して撓む他の弾性腕部によりかかる事態に対する安全性を多重に確保でき、また、一つの弾性腕部の接触部へ異物が付着しても他の弾性腕部の接触部が独立して平型導体に対する適切な接圧を維持し、複数の接触部による接触確実性が担保される。   In the present invention, as described above, a plurality of elastic arm portions provided on the terminal are formed in parallel, and each elastic arm portion has a contact portion on a free end side thereof that can be flexibly displaced independently of each other; Therefore, even if the bending characteristics of one elastic arm part deteriorate due to fatigue, the other elastic arm parts that bend independently can ensure multiple safety against such a situation, and the contact of one elastic arm part Even if a foreign substance adheres to the part, the contact part of the other elastic arm part independently maintains an appropriate contact pressure against the flat conductor, and the contact reliability by the plurality of contact parts is ensured.

以下、添付図面にもとづき、本発明の実施形態について説明する。   Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

図１（Ａ）は、本実施形態のコネクタの外観そしてこれに接続される平型導体の接続前における接続部分が設けられている前端部を示す斜視図、図１（Ｂ）は接続後の斜視図である。   FIG. 1A is a perspective view showing the appearance of the connector of this embodiment and a front end portion provided with a connection portion before connection of a flat conductor connected thereto, and FIG. 1B is a view after connection. It is a perspective view.

図１（Ａ），（Ｂ）において、符号１は本実施形態の平型導体用電気コネクタであり、符号Ｆがこのコネクタ１に接続される平型導体である。   In FIGS. 1A and 1B, reference numeral 1 denotes a flat conductor electrical connector according to this embodiment, and reference numeral F denotes a flat conductor connected to the connector 1.

平型導体Ｆは、その前端部（図１（Ａ）にてコネクタ１寄り部分をなす右上縁部に上記コネクタ１との接続部分を有し、後方（図１（Ａ），（Ｂ）にて左下方）に長く延びているが、図（Ａ）では接続部分のすぐ後方位置までの部分が示されていて、それより後方は図示が省略されている。上記平型導体Ｆは、本実施形態では、前端部下面の被覆が除去されて接続回路部が露呈して接続部分をなしている。この接続部分は、コネクタとの接続時の強度向上のため通常、上面に補強シートが施されている。   The flat conductor F has a connection portion with the connector 1 at its front end (upper right edge portion forming a portion closer to the connector 1 in FIG. 1 (A)) and rearward (see FIGS. 1 (A) and (B)). In Fig. (A), the portion up to the position immediately behind the connection portion is shown, and the illustration behind the connection portion is omitted. In the embodiment, the coating on the lower surface of the front end portion is removed to expose the connection circuit portion, and this connection portion is usually provided with a reinforcing sheet on the upper surface in order to improve the strength when connected to the connector. Has been.

かかる平型導体Ｆの接続部分には、その幅方向両側縁に突出部によって被係止部Ｆ１が形成されている。この突出形状の被係止部Ｆ１は後述の柱部に係止して、平型導体Ｆの抜け防止に寄与する。   In the connecting portion of the flat conductor F, a locked portion F1 is formed by protruding portions on both side edges in the width direction. This protruding portion F1 to be locked is locked to a pillar portion to be described later and contributes to preventing the flat conductor F from coming off.

一方、コネクタ１は、コネクタ本体２と、該コネクタ本体２に対し、後述の端子により可動に支持されている可動部材３から成っている（図２をも参照）。本実施形態では、可動部材３は回動操作を受ける。   On the other hand, the connector 1 includes a connector main body 2 and a movable member 3 that is movably supported by terminals described later with respect to the connector main body 2 (see also FIG. 2). In the present embodiment, the movable member 3 receives a turning operation.

コネクタ本体２は、電気絶縁材から作られたハウジング１０と、金属板の平坦面を維持して作られていてハウジング１０により保持されている端子２０と、この端子と同様に金属板から作られていて、ハウジング１０により保持されている金具４０とを有している。これらの端子２０そして金具４０については、後述する。   The connector body 2 is made of a housing 10 made of an electrical insulating material, a terminal 20 made by maintaining a flat surface of a metal plate and held by the housing 10, and made of a metal plate in the same manner as this terminal. And a metal fitting 40 held by the housing 10. The terminals 20 and the metal fitting 40 will be described later.

ハウジング１０は、電気絶縁材料を成形して作られていて、上記平型導体Ｆの幅方向に長く、比較的高さ寸法の小さい略直方体外形を有しており、図２（Ａ）の断面図に見られるように、前後方向（図２（Ａ）にて前方が右方、後方が左方）に貫通するスリット状の複数の端子溝１１が上記幅方向に配列形成されている。端子溝１１には、端子２０が対応して挿入され保持されており、上記幅方向で端子の配列範囲を形成している。該端子の配列範囲の外側には、金具４０を保持させるための金具溝１４が端子溝１１と同様なスリット状に、前後方向に貫通して形成されている。   The housing 10 is formed by molding an electrically insulating material, and has a substantially rectangular parallelepiped outer shape that is long in the width direction of the flat conductor F and has a relatively small height dimension. As seen in the figure, a plurality of slit-like terminal grooves 11 penetrating in the front-rear direction (the front side is the right side and the rear side is the left side in FIG. 2A) are arranged in the width direction. Terminals 20 are correspondingly inserted and held in the terminal grooves 11, and form an array range of terminals in the width direction. A metal groove 14 for holding the metal fitting 40 is formed in the same slit shape as the terminal groove 11 in the front-rear direction outside the terminal arrangement range.

既述したように上記端子２０そして金具４０が金属板の平坦な板面と対面するように配列されている関係上、これらを挿入保持する端子溝１１そして金具溝１４も、端子配列方向における溝幅が端子２０そして金具４０をそれぞれ板厚方向で定まる寸法に作られており、図２（Ａ）そして（Ｂ）において、紙面に直角な方向を上記溝幅としている。上記金具４０は、本発明の主眼するところではないので、コネクタを補強そして回路基板への取付強度を向上させるということにとどめ、以下説明を省略する。本実施形態では、上記端子２０は、後に詳述するように、一部が金属板を折り曲げて二枚構造をなしており、したがって、上記端子溝１１もこれに見合った溝幅を有していて、一つの端子溝１１には、板厚一枚分を収容する部分と二枚分を収容する部分とが存在している。   Since the terminal 20 and the metal fitting 40 are arranged so as to face the flat plate surface of the metal plate as described above, the terminal groove 11 and the metal groove 14 for inserting and holding them are also grooves in the terminal arrangement direction. The widths of the terminals 20 and the metal fittings 40 are each determined in the thickness direction. In FIGS. 2A and 2B, the direction perpendicular to the paper surface is the groove width. Since the metal fitting 40 is not the main point of the present invention, only the reinforcement of the connector and the attachment strength to the circuit board are improved, and the description thereof is omitted below. In the present embodiment, as described in detail later, the terminal 20 has a two-piece structure in which a part of the metal plate is bent, and thus the terminal groove 11 has a groove width corresponding to this. One terminal groove 11 has a portion for accommodating one sheet thickness and a portion for accommodating two sheets.

端子２０は、図２（Ａ），（Ｂ）そして図３に見られるように、上腕部２１と下腕部２２そして接続部２３を有しており、上腕部２１と下腕部２２は、それらの基部が連結部２４で連結されていて、ハウジング１０の端子溝１１を形成する上壁部１２と下壁部１３の内面に沿って位置し、接続部２３は上記下腕部２２の下部位置から連結部２４に対し上記下腕部２２とはと逆方向である前方に延びハウジング１０外へ突出している。該接続部２３は、ハウジング１０外では下向きに傾斜した後に前方に向け延びていて、その下縁は、回路基板（図示せず）の対応回路部に接するように位置しており、この対応回路部と半田接続される。上記上腕部２１は基部の上縁の係止突起２１Ａと連結部２４の上縁に係止突起２１Ｂを有し、前方から後方に向けてから端子２０を所定位置までの上記端子溝１１への挿入したときにハウジング１０の上壁部１２の内面に喰い込んで端子２０の抜けの防止を図っている。該上腕部２１は、紙面内での撓みに関し、比較的剛性が高く、特に下腕部２２との比較において剛性が高い。この上腕部２１の先端部２５は、高さ方向に幅広となっている。   As shown in FIGS. 2A and 2B and FIG. 3, the terminal 20 has an upper arm portion 21, a lower arm portion 22, and a connection portion 23, and the upper arm portion 21 and the lower arm portion 22 are These base portions are connected by a connecting portion 24 and are located along the inner surfaces of the upper wall portion 12 and the lower wall portion 13 that form the terminal groove 11 of the housing 10, and the connecting portion 23 is a lower portion of the lower arm portion 22. From the position, it extends forward in the direction opposite to the lower arm portion 22 with respect to the connecting portion 24 and protrudes out of the housing 10. The connection portion 23 is inclined downward and extends forward outside the housing 10, and its lower edge is positioned so as to contact a corresponding circuit portion of a circuit board (not shown). Soldered to the part. The upper arm portion 21 has a locking projection 21A on the upper edge of the base portion and a locking projection 21B on the upper edge of the connecting portion 24, and the terminal 20 is connected to the terminal groove 11 from the front to the rear to the predetermined position. When inserted, the inner wall of the upper wall portion 12 of the housing 10 is bitten to prevent the terminal 20 from coming off. The upper arm portion 21 has a relatively high rigidity with respect to bending in the paper, and particularly has a higher rigidity than the lower arm portion 22. The distal end portion 25 of the upper arm portion 21 is wide in the height direction.

上記先端部２５の下縁部には凹湾曲した溝状の案内支持部２６が下方に向け開口して形成されている。この案内支持部２６は、後述する可動部材を回動可能に案内支持するために形成されていて可動部材に対して軸受の機能を有する。この案内支持部２６は、剛性の高い上記上腕部２１の先端部分に位置しているだけなので、該上腕部２１の全体に対して剛性を阻害していない。   A groove-shaped guide support portion 26 that is concavely curved is formed at the lower edge portion of the tip portion 25 so as to open downward. This guide support portion 26 is formed to guide and support a movable member, which will be described later, in a rotatable manner, and has a bearing function with respect to the movable member. Since the guide support portion 26 is only located at the tip portion of the upper arm portion 21 having high rigidity, the rigidity of the entire upper arm portion 21 is not hindered.

端子２０の下腕部２２は、上腕部２１に比し幅（図での高さ寸法方向）が狭く形成されていて、弾性腕部として形成されており、紙面に平行な面内で上下方向に撓み可能となっている。この下腕部２２は、上述のごとく弾性腕部として形成されており、主弾性腕部２７と副弾性腕部２８とを有している。上記下腕部２２は、その基部となる連結部２４寄り位置で上記下腕部２２の上縁の一部に折曲部２９を有していて、該折曲部２９で下腕部２２の板厚方向に折曲されており、板厚方向で上記連結部２４と同じ位置で同一面を維持している主弾性腕部２７と、板厚方向で該主弾性腕部２７に対して折曲された分だけずれて位置することで主弾性腕部２７と並列をなしていて板厚同士で互いに対面する副弾性腕部２８を形成している。   The lower arm portion 22 of the terminal 20 has a narrower width (in the height direction in the figure) than the upper arm portion 21 and is formed as an elastic arm portion. Can be bent. The lower arm portion 22 is formed as an elastic arm portion as described above, and has a main elastic arm portion 27 and a sub elastic arm portion 28. The lower arm portion 22 has a bent portion 29 at a part of the upper edge of the lower arm portion 22 at a position near the connecting portion 24 serving as a base thereof. A main elastic arm portion 27 that is bent in the plate thickness direction and maintains the same surface at the same position as the connecting portion 24 in the plate thickness direction, and is bent with respect to the main elastic arm portion 27 in the plate thickness direction. The sub-elastic arm portions 28 that are parallel to the main elastic arm portion 27 and face each other at the plate thickness are formed by being shifted by the bent amount.

図３からも判るように、端子２０を板厚方向に見たときに、上記主弾性腕部２７と副弾性腕部２８とは、両者間に隙間を形成している状態で、外形がほぼ一致するよう形状そして大きさになっている。基部から自由端（図にて左端）までの長さである腕長の点で、主弾性腕部２７の方が副弾性腕部２８よりも、若干大きくなっていることが相違点である。   As can be seen from FIG. 3, when the terminal 20 is viewed in the plate thickness direction, the main elastic arm portion 27 and the sub elastic arm portion 28 are substantially in the form of a gap between them. Shaped and sized to match. The main difference is that the main elastic arm portion 27 is slightly larger than the sub elastic arm portion 28 in terms of the arm length which is the length from the base portion to the free end (left end in the figure).

上記主弾性腕部２７そして副弾性腕部２８のそれぞれの下縁は自由端寄りの後半部では上方に向け傾斜した斜部２７Ａ，２８Ａを有しており、ハウジング１０の下壁部１３の上面との間に隙間を形成し、かつその隙間が上記自由端側へ向け大きくなるようにされている。上記弾性腕部２７，２８の基部は端子溝１１の下面、すなわちハウジング１０の下壁部１３の上面上に支えられる被支持部である。そして、該主弾性腕部２７そして副弾性腕部２８の自由端には、それらの上縁で上記上腕部２１の案内支持部２６の方に向け上方へ突出した接触部２７Ｂ、２８Ｂが形成されている。上述したように、自由端まで主弾性腕部２７の腕長が副弾性腕部２８よりも若干大きくなっているので、その分だけ、主弾性腕部２７の接触部２７Ｂの方が副弾性腕部２８の接触部２８Ｂよりも後方にずれて位置している。両弾性腕部２７，２８の接触部２７Ｂ，２８Ｂは、上方への突出量はほぼ同じである。   The lower edges of the main elastic arm portion 27 and the sub elastic arm portion 28 have oblique portions 27A and 28A inclined upward in the latter half portion near the free end, and the upper surface of the lower wall portion 13 of the housing 10. Is formed so that the gap increases toward the free end. The base portions of the elastic arm portions 27 and 28 are supported portions supported on the lower surface of the terminal groove 11, that is, the upper surface of the lower wall portion 13 of the housing 10. The free ends of the main elastic arm portion 27 and the sub elastic arm portion 28 are formed with contact portions 27B and 28B protruding upward toward the guide support portion 26 of the upper arm portion 21 at their upper edges. ing. As described above, since the arm length of the main elastic arm portion 27 is slightly larger than that of the sub elastic arm portion 28 up to the free end, the contact portion 27B of the main elastic arm portion 27 is correspondingly larger. The portion 28 is located behind the contact portion 28B. The contact portions 27B and 28B of both elastic arm portions 27 and 28 have substantially the same amount of upward protrusion.

本実施形態では、好ましい形態として、上記主弾性腕部２７もしくは副弾性腕部２８の少なくとも一方に、連結部２４寄りとなる基部近傍位置の上記被支持部に小さな凸部２７Ｃ（もしくは２８Ｃ）がエンボス加工により両弾性腕部２７，２８の対面方向に突出形成されていて、両弾性腕部２７，２８は、上記凸部２７Ｃ（もしくは２８Ｃ）で点状に当接して、ほぼ腕長の全長で確実に非接触となるように隙間を形成し、斜部２７Ａ，２８Ａにて主たる弾性部が構成される両弾性腕部２７、２８が互いに独立して撓み弾性変位が可能となっている。   In this embodiment, as a preferred embodiment, a small convex portion 27C (or 28C) is formed on the supported portion near the base portion close to the connecting portion 24 on at least one of the main elastic arm portion 27 or the sub elastic arm portion 28. Both elastic arm portions 27 and 28 are formed so as to protrude in the facing direction by embossing, and both elastic arm portions 27 and 28 come into contact with each other in the form of dots at the convex portions 27C (or 28C), and are almost the full length of the arm length. Thus, a gap is formed so as to be surely non-contact, and both elastic arm portions 27, 28 constituting the main elastic portion at the inclined portions 27A, 28A are flexed independently of each other to enable elastic displacement.

ハウジング１０は、既述したように、金属板から形成されその板面を維持している上記端子２０を前方から挿入するためのスリット状の端子溝１１が紙面に平行に端子の数だけ配列形成されている。端子２０は、上述のごとく、上腕部２１が一枚形成、下腕部２２が二枚折形成されているので、上記端子溝１１も、これに対応して、ハウジング１０の上壁部１２には狭い溝幅、下壁部１３には広い溝幅をもって形成されている。かかる端子溝１１の上端そして下端を規制するハウジング１０の上壁部１２にそして下壁部１３は上記端子２０を保持する。基部をなす連結部２４の下縁がハウジング１０の下壁部１３の内面に接し、既述のごとく、上腕部２１の係止突起２１Ａ，２１Ｂがハウジングの上壁部１２に喰い込んで、端子位置を確保すると共に抜けを防止する。   As described above, the housing 10 is formed of a metal plate, and the slit-like terminal grooves 11 for inserting the terminals 20 that maintain the plate surface from the front are arranged in parallel to the paper surface as many as the number of terminals. Has been. As described above, since the terminal 20 is formed with one upper arm portion 21 and two lower arm portions 22 are folded, the terminal groove 11 is formed in the upper wall portion 12 of the housing 10 correspondingly. Is formed with a narrow groove width and a wide groove width in the lower wall portion 13. The upper wall portion 12 of the housing 10 that restricts the upper and lower ends of the terminal groove 11 and the lower wall portion 13 hold the terminals 20. The lower edge of the connecting portion 24 forming the base is in contact with the inner surface of the lower wall portion 13 of the housing 10, and as described above, the locking projections 21A and 21B of the upper arm portion 21 bite into the upper wall portion 12 of the housing, Secure the position and prevent it from coming off.

上記ハウジング１０は、その後半部（左半部）で上壁部１２が不存在となっていて、該後半部は上方に開放されており、平型導体Ｆの受入れのための受入部１５を形成している。受入部１５には、コネクタ幅方向両端位置に、ハウジング１０の下壁１３から立ち上がる柱部１６が立設されていて、所定位置までの挿入後の平型導体Ｆの被係止部Ｆ１の後縁を係止して平型導体Ｆの抜け防止を図っている。該受入部１５は、後述の可動部材３の配置をも許容している。かかる受入部１５には、上記端子２０の上腕部２１と下腕部２２のそれぞれの自由端部が位置しており、両者の間に平型導体Ｆを挿入可能とする受入空間１５Ａが形成されている。   The housing 10 has no upper wall portion 12 in the latter half (left half) thereof, and the latter half is opened upward, and the receiving portion 15 for receiving the flat conductor F is provided. Forming. Columns 16 rising from the lower wall 13 of the housing 10 are erected on the receiving portion 15 at both ends in the connector width direction. After the inserted portion F1 of the flat conductor F after insertion up to a predetermined position. The edge is locked to prevent the flat conductor F from coming off. The receiving portion 15 also allows the arrangement of the movable member 3 described later. In the receiving portion 15, the free end portions of the upper arm portion 21 and the lower arm portion 22 of the terminal 20 are positioned, and a receiving space 15 </ b> A in which a flat conductor F can be inserted is formed therebetween. ing.

上記ハウジング１０の受入部１５には、絶縁材で作られた可動部材３が配置されている。該可動部材３は、図２（Ａ）の開位置と図２（Ｂ）の閉位置との間を回動自在に、端子２０の上記案内支持部２６により案内支持されている。上記可動部材３は、先端側（図２（Ａ）にて上端側）の操作部３１と、逆側の溝部３２とを有している。操作部３１は可動部材３へ操作力として回動力を与えるための部分であり、溝部３２は端子２０の先端部２５を収めるために形成されている。したがって、溝部３２は端子２０に対応して櫛歯状にスリットを形成している。そして、該溝部３２内に溝部３２の内面同士を連結している軸部３３が設けられていて、該軸部３３が端子２０の案内支持部２６によって回動自在に案内支持されている。   A movable member 3 made of an insulating material is disposed in the receiving portion 15 of the housing 10. The movable member 3 is guided and supported by the guide support portion 26 of the terminal 20 so as to be rotatable between an open position in FIG. 2A and a closed position in FIG. The movable member 3 has an operation portion 31 on the distal end side (upper end side in FIG. 2A) and a groove portion 32 on the opposite side. The operation portion 31 is a portion for applying a turning force as an operation force to the movable member 3, and the groove portion 32 is formed to accommodate the distal end portion 25 of the terminal 20. Therefore, the groove portion 32 forms a comb-like slit corresponding to the terminal 20. A shaft portion 33 that connects the inner surfaces of the groove portion 32 is provided in the groove portion 32, and the shaft portion 33 is rotatably supported by the guide support portion 26 of the terminal 20.

上記可動部材３は、図２（Ａ）のごとく、可動部材３が直立よりもさらに回動して傾いた姿勢の最大限回動状態の開位置にきていて、上記端子２０の上腕部２１と下腕部２２の自由端同士間の空間であって平型導体Ｆの挿入を許容する受入空間１５Ａを開放している。かかる開位置における姿勢となっている図２（Ａ）の可動部材３の下端縁３４は、平型導体Ｆの挿入方向と同じ方向を成す面として形成されており、平型導体Ｆはこの下端縁３４に沿って挿入される。すなわち、この下端縁３４は、可動部材３がその軸部３３から操作部３１に向け延びている方向に対しては、傾斜面をなしている。可動部材３はこの下端縁３４と背面３８（図２（Ａ）にて位置する可動部材３の左面）とが交差する部分は、略角部をなしていて、加圧部３６を形成し、可動部材３が閉位置へ向いた回動中に平型導体Ｆをこの加圧部３６で押圧し、閉位置へ達する直前に押圧力が最大値をとるようになっている。   As shown in FIG. 2A, the movable member 3 is at the open position in the maximum rotation state in which the movable member 3 is further rotated from the upright position and tilted. 15A, which is a space between the free ends of the lower arm portion 22 and allows insertion of the flat conductor F, is opened. The lower end edge 34 of the movable member 3 in FIG. 2A that is in the open position is formed as a surface that forms the same direction as the insertion direction of the flat conductor F, and the flat conductor F is the lower end. Inserted along edge 34. That is, the lower edge 34 forms an inclined surface with respect to the direction in which the movable member 3 extends from the shaft portion 33 toward the operation portion 31. In the movable member 3, a portion where the lower end edge 34 and the back surface 38 (the left surface of the movable member 3 located in FIG. 2A) intersects forms a substantially corner portion to form a pressing portion 36. During the rotation of the movable member 3 toward the closed position, the flat conductor F is pressed by the pressing portion 36, and the pressing force takes the maximum value immediately before reaching the closed position.

以上のごとくの本実施形態のコネクタは、次の要領で使用される。   The connector of this embodiment as described above is used in the following manner.

（１）先ず、コネクタ１を回路基板（図示せず）上の所定位置へ配置し、端子２０の接続部２３を該回路基板の対応回路部と半田等により接続する。金具４０も同様に回路基板へ半田固定される。   (1) First, the connector 1 is disposed at a predetermined position on a circuit board (not shown), and the connection portion 23 of the terminal 20 is connected to the corresponding circuit portion of the circuit board by soldering or the like. Similarly, the metal fitting 40 is fixed to the circuit board by soldering.

（２）次に、可動部材３を、図１（Ａ）に示される開位置にまで上方へ向け時計まわりに回動し、この開位置に維持しておく。   (2) Next, the movable member 3 is rotated clockwise to the open position shown in FIG. 1 (A) and kept in this open position.

（３）可動部材３が開位置にあると、受入部１５そして受入空間１５Ａは左方に大きく開放された状態が確保される。したがって、平型導体Ｆの挿入側から受入空間１５Ａの周辺が良く見出される。作業者は、平型導体Ｆを、その接続部分が下面となるようにして、この受入空間１５Ａ、すなわち、端子２０の上腕部２１と下腕部２２の間に挿入し、平型導体Ｆの先端が受入空間１５Ａの奥部に到達するまで挿入する。   (3) When the movable member 3 is in the open position, the receiving portion 15 and the receiving space 15A are ensured to be largely open to the left. Therefore, the periphery of the receiving space 15A is often found from the insertion side of the flat conductor F. The operator inserts the flat conductor F into the receiving space 15A, that is, between the upper arm portion 21 and the lower arm portion 22 of the terminal 20 so that the connecting portion is the lower surface. Insert until the tip reaches the back of the receiving space 15A.

平型導体Ｆは、上記所定位置まで挿入されると、その接続部分は、端子２０の接触部２７Ｂ，２７Ｂ上に位置する。   When the flat conductor F is inserted to the predetermined position, the connecting portion is located on the contact portions 27B and 27B of the terminal 20.

（４）所定位置まで平型導体Ｆを挿入した後、可動部材３を反時計まわりに回動して図１（Ａ）の位置から図１（Ｂ）の閉位置へもたらす。可動部材３はその加圧部３６および背面３８で平型導体Ｆを接触部２７Ｂ，２８Ｂへ圧し、平型導体Ｆは両接触部２７Ｂ，２７Ｂと電気的に接続される。   (4) After inserting the flat conductor F to a predetermined position, the movable member 3 is rotated counterclockwise to bring it from the position shown in FIG. 1 (A) to the closed position shown in FIG. 1 (B). The movable member 3 presses the flat conductor F to the contact portions 27B and 28B at the pressurizing portion 36 and the back surface 38, and the flat conductor F is electrically connected to both the contact portions 27B and 27B.

既述したように、自由端に上記接触部２７Ｂが設けられている主弾性腕部２７と、自由端に接触部２８Ｂが設けられている副弾性腕部２８は、それぞれ自由端に向け延びる片持ち梁を形成して互いに独立して弾性撓み可能であり、しかし、両者間には隙間が形成されているので、弾性撓み時に、両者は摩擦力を作用し合うこともない。したがって、両者は、平型導体Ｆに圧せられる結果、独立して撓んでそれぞれ所定の接圧が得られる。   As described above, the main elastic arm portion 27 provided with the contact portion 27B at the free end and the sub elastic arm portion 28 provided with the contact portion 28B at the free end are each extended toward the free end. The cantilever can be formed and elastically bent independently of each other. However, since a gap is formed between the two, the frictional force does not act between the two at the time of elastic bending. Accordingly, as a result of being pressed against the flat conductor F, both of them are bent independently and a predetermined contact pressure is obtained.

したがって、接触部２７Ｂと接触部２８Ｂのいずれか一方に、ゴミ等の異物が付着していたときには、一方では接触での不具合を生ずることがあり得るが、他方では異物が付着しておらず、しかも独立して撓むので、平型導体Ｆとの間で所定の接圧を確保した状態での接触を得る。   Therefore, when foreign matter such as dust adheres to one of the contact portion 27B and the contact portion 28B, on the one hand, it may cause a malfunction in contact, but on the other hand, no foreign matter adheres, And since it bends independently, the contact in the state which ensured the predetermined contact pressure between the flat conductors F is obtained.

次に、既述の端子２０の製造要領に関して説明する。   Next, the manufacturing procedure of the terminal 20 will be described.

図４は、金属板に折曲部２９を形成して図３のような端子２０を得る前の半加工状態の中間素材の平面図である。   FIG. 4 is a plan view of the intermediate material in a semi-processed state before the bent portion 29 is formed on the metal plate to obtain the terminal 20 as shown in FIG.

図４において、帯状の金属板を打ち抜いて形状づけられた中間素材Ｍは、送りのため係止孔Ｃ１が形成されたキャリア部分Ｃと、最終的に端子となる端子部分Ｔとを有している。端子部分Ｔとキャリア部分Ｃとは、くびれて形成された連接部Ｊによりつながっている。   In FIG. 4, an intermediate material M formed by punching a strip-shaped metal plate has a carrier portion C in which a locking hole C1 is formed for feeding, and a terminal portion T that finally becomes a terminal. Yes. The terminal portion T and the carrier portion C are connected by a connecting portion J formed constricted.

上記端子部分Ｔは、上記折曲部２９を形成する折曲加工を受ける前には平坦な面に、折曲加工後に端子の各部をなす部分を有している。端子２０の各部と折曲前の対応部分とを理解しやすくするために、この対応部分を端子各部の符号の頭にＴを付して示すこととする。   The terminal portion T has a portion that forms each part of the terminal after the bending process on a flat surface before receiving the bending process for forming the bending part 29. In order to make it easy to understand each part of the terminal 20 and the corresponding part before bending, the corresponding part is indicated with T at the beginning of the reference numeral of each terminal part.

上記連接部Ｊは、上記端子部分Ｔをその基部となる連結部Ｔ２４と上記キャリア部分Ｃとを連接している。該連結部Ｔ２４の上部からは左方に向け上腕部Ｔ２１が、下部からは左方に向け下腕部Ｔ２２がそして右方に向け接続部Ｔ２３がそれぞれ延びている。下腕部Ｔ２２は、連結部Ｔ２４の下部から左方へ直状に延びている主弾性腕部Ｔ２７と一旦上方へ向って主弾性腕部Ｔ２７から分枝してから左方へ延びて逆Ｌ字状をなす副弾性腕部Ｔ２８とを有している。副弾性腕部Ｔ２８はその腕長が主弾性腕部Ｔ２７よりも若干短い。上記分枝部分は折曲部Ｔ２９を形成している。   The connecting portion J connects the terminal portion T to the connecting portion T24 serving as a base thereof and the carrier portion C. From the upper part of the connecting part T24, an upper arm part T21 extends leftward, from the lower part a lower arm part T22 extends leftward, and a connecting part T23 extends rightward. The lower arm portion T22 has a main elastic arm portion T27 extending straight from the lower portion of the connecting portion T24 to the left and once branched upward from the main elastic arm portion T27, and then extends to the left and reverse L And a sub-elastic arm T28 having a letter shape. The sub-elastic arm portion T28 has a slightly shorter arm length than the main elastic arm portion T27. The branched portion forms a bent portion T29.

かかる端子部分Ｔは、上記折曲部Ｔ２９が折曲線Ｔ２９−１にて折り曲げられて、折り曲げ後に図３に見られるように主弾性腕部２７と副弾性腕部２８とがその板面同士が平行な状態で板厚方向にて対面するようにして、並列をなすようになる。折曲加工は、その加工上、主弾性腕部２７と副弾性腕部２８との間に隙間を残すようになり、この隙間が両者を非接触状態に保つ。積極的に隙間を形成するには、両者のいずれかが一方に、エンボス加工で既出の凸部２７Ｃを設けるのも一策である。このようにして、端子部分Ｔが形成された後あるいは挿入時に、連接部Ｊを切断線Ｊ−１の位置で切断して、キャリア部分Ｃから切り離す。中間素材を示す図４に見られるように、端子部分Ｔを形成すると、上腕部Ｔ２１と下腕部Ｔ２２の主弾性腕部Ｔ２７との間の範囲内に副弾性腕部Ｔ２８が位置するので、素材としての金属板は加工により捨てる部分があまりなく、副弾性腕部Ｔ２８を有しない端子の場合と比べ、端子部分Ｔ同士のピッチ幅も素材コストも変わらない。   The terminal portion T is formed by bending the bent portion T29 at a folding line T29-1 and the main elastic arm portion 27 and the auxiliary elastic arm portion 28 are arranged between the plate surfaces as shown in FIG. In parallel, they face each other in the plate thickness direction, and are arranged in parallel. In the bending process, a gap is left between the main elastic arm portion 27 and the sub elastic arm portion 28 in the processing, and this gap keeps both in a non-contact state. In order to positively form a gap, it is also possible to provide one of the two with the above-described convex portion 27C by embossing. In this way, after the terminal portion T is formed or inserted, the connecting portion J is cut at the position of the cutting line J-1 and separated from the carrier portion C. As shown in FIG. 4 showing the intermediate material, when the terminal portion T is formed, the sub elastic arm portion T28 is located in the range between the upper arm portion T21 and the main elastic arm portion T27 of the lower arm portion T22. The metal plate as a material does not have a lot of parts to be discarded by processing, and the pitch width between the terminal portions T and the material cost do not change compared to the case of the terminal without the sub-elastic arm portion T28.

本実施形態において、下腕部２２を折曲部２９の形成により主弾性腕部２７と副弾性腕部２８とを設けるのに際し、折曲部２９は図３に図示された位置に限定されず変更が可能である。図５（Ａ）は、図３の端子を参考のために再度示すものであり、折曲部２９は主弾性腕部２７の基部の上縁に位置しており、折曲前の副弾性腕部Ｔ２８（図にて破線で表示）は、すでに図４で示され、そして再度図５（Ａ）に示されるように、折曲線Ｔ２９−１に対して上側に位置して主弾性腕部２７と平行に延びている。   In the present embodiment, when the lower elastic portion 22 is provided with the main elastic arm portion 27 and the auxiliary elastic arm portion 28 by forming the bent portion 29, the bent portion 29 is not limited to the position illustrated in FIG. It can be changed. FIG. 5A shows the terminal of FIG. 3 again for reference. The bent portion 29 is located on the upper edge of the base portion of the main elastic arm portion 27, and the auxiliary elastic arm before bending is shown. The portion T28 (indicated by a broken line in the figure) is already shown in FIG. 4 and again as shown in FIG. It extends in parallel.

次に、図５（Ｂ）に見られる例では、図５（Ａ）では折曲部２９が主弾性腕部２７の基部における上縁に位置していたのに対し、主弾性腕部２７の基部における下縁に位置しており、副弾性腕部２８は上方に向け折り曲げられている。したがって、折曲前の副弾性腕部Ｔ２８（図にて破線で表示）は、折曲線Ｔ２９−１に対して下側に位置して主弾性腕部２７と平行に延びている。   Next, in the example seen in FIG. 5 (B), the bent portion 29 is located at the upper edge of the base portion of the main elastic arm portion 27 in FIG. It is located at the lower edge of the base portion, and the secondary elastic arm portion 28 is bent upward. Therefore, the secondary elastic arm portion T28 (shown by a broken line in the figure) before bending is positioned below the folding line T29-1 and extends in parallel with the main elastic arm portion 27.

次に、図５（Ｃ）に見られる例では、連結部２４から延出している接続部２３の端部縁に折曲部２９が位置しており、折曲前の副弾性腕部Ｔ２８（図にて破線で表示）は右方に延びていて上記接続部２３の端部縁に位置する折曲線Ｔ２９−１で左方へ折曲加工を受けることとなる。この例では、図５（Ａ），（Ｂ）の例に比し、接続部２３が二重に形成されるので、回路基板への半田接続による固定がさらに強力となる。勿論、主弾性腕部２７の接続部２３の下縁に対応する部分で副弾性腕部２８を切り込んで下縁を回路基板から浮いた位置として、半田接続を主弾性腕部２７の接続部２３のみで行うことも可能である。   Next, in the example seen in FIG. 5C, the bent portion 29 is located at the end edge of the connecting portion 23 extending from the connecting portion 24, and the auxiliary elastic arm portion T28 (before bending) (Shown by a broken line in the figure) extends to the right and undergoes a bending process to the left at a folding line T29-1 located at the end edge of the connecting portion 23. In this example, as compared with the example of FIGS. 5A and 5B, since the connecting portion 23 is formed in a double manner, the fixing by the solder connection to the circuit board becomes stronger. Of course, the secondary elastic arm portion 28 is cut at a portion corresponding to the lower edge of the connecting portion 23 of the main elastic arm portion 27, and the lower edge is lifted from the circuit board, and the solder connection is performed at the connecting portion 23 of the main elastic arm portion 27. It is also possible to do it alone.

さらに、本実施形態では、図示しないが、接続部２３を板厚方向に偏倚して位置させることも可能である。既出の例のように弾性腕部が二つ設けられている場合は勿論、例えば、異なる位置に折曲部を設けて、三つ以上の弾性腕部を形成した場合であっても、連結部と接続部との間の位置でプレス等により板厚方向での偏倚加工を施し、この位置を境として連結部側に対して接続部が板厚方向に偏倚させるようにすることで、任意の弾性腕部に対して所望量だけ偏倚させることが可能である。例えば、下腕部が主弾性腕部と副弾性腕部の二つを有しているとき、それらの中間に接続部を位置させることができる。この接続部を偏倚させることの利点は、回路基板の接続部半田接続用のパッドの位置が通常、標準的に定まった位置に設けられているので、この位置を変更せずに、上記接続部の位置を偏倚させることで、これに対応可能となる。 Furthermore, in this embodiment, although not shown, it is also possible to position the connecting portion 23 so as to be biased in the plate thickness direction. Of course, when two elastic arm portions are provided as in the above example, for example, even when three or more elastic arm portions are formed by providing bent portions at different positions, the connecting portion By applying a biasing process in the plate thickness direction by a press or the like at a position between the connecting portion and the connecting portion, the connecting portion is biased in the plate thickness direction with respect to the connecting portion side with this position as a boundary. It is possible to deflect the elastic arm portion by a desired amount . For example, when the lower arm portion has two of a main elastic arm portion and a sub elastic arm portion, the connecting portion can be positioned between them. The advantage of biasing this connecting portion is that the position of the pad for soldering the connecting portion of the circuit board is usually provided at a standard position, so that the connecting portion can be changed without changing this position. This can be accommodated by biasing the position of.

本実施形態では、下腕部を多重にするものであったが、下腕部に加えて他の部分を多重にすることも、さらには、端子全体を多重にすることも可能である。例えば、上腕部を重複させた場合には、案内支持部の支持力が向上するので、端子の板厚を更に薄くすることができる。   In the present embodiment, the lower arm portion is multiplexed. However, in addition to the lower arm portion, other portions can be multiplexed, and further, the entire terminals can be multiplexed. For example, when the upper arm portion is overlapped, the support force of the guide support portion is improved, so that the thickness of the terminal can be further reduced.

本実施形態では、さらに上腕部が可動部材を案内支持する案内支持部を有している場合でも、下腕部に加え上腕部をも折曲部を介して二つの腕部とすることが可能となる。この場合、支持力が向上する。   In the present embodiment, even when the upper arm portion has a guide support portion that guides and supports the movable member, the upper arm portion can be made to have two arm portions via the bent portion in addition to the lower arm portion. It becomes. In this case, the supporting force is improved.

図１ないし図５の例では、端子が上腕部と下腕部とを有し、両者が自由端とは反対側の端部で連結部により連結されている、いわゆるフロントフリップ形式であったが、本発明はこれに限定されず、上腕部を有することなく下腕部のみを有し、該下腕部が二つ以上の弾性腕部から成っているようにすることができる。さらには、図６のように、上腕部２１と下腕部２２がその長手方向中間位置で連結部２４により連結されていて、長円断面形状のカム部３７を有する可動部材３の回動時に、上腕部２１の右端側の被圧部２１Ｃが上記カム部３７により上方に撓み、梃子の原理で上腕部２１の左端側が下方に撓んで平型導体を圧する、いわゆるバックフリップ形式にも、適用可能である。図６に図示の例では、図３の例とは異なり、上腕部２１に接触部２７Ｂ，２８Ｂをそれぞれ有する主弾性腕部２７と副弾性腕部２８が設けられている。   In the example of FIGS. 1 to 5, the terminal has a so-called front flip type in which the terminal has an upper arm portion and a lower arm portion, and both are connected by a connecting portion at an end opposite to the free end. However, the present invention is not limited to this, it is possible to have only the lower arm portion without having the upper arm portion, and the lower arm portion can be composed of two or more elastic arm portions. Further, as shown in FIG. 6, the upper arm 21 and the lower arm 22 are connected by the connecting portion 24 at an intermediate position in the longitudinal direction, and when the movable member 3 having the oval cross-sectional cam portion 37 is rotated. Also applied to the so-called back flip type in which the pressure-receiving portion 21C on the right end side of the upper arm portion 21 is bent upward by the cam portion 37 and the left end side of the upper arm portion 21 is bent downward by the lever principle to press the flat conductor. Is possible. In the example shown in FIG. 6, unlike the example of FIG. 3, a main elastic arm portion 27 and a sub elastic arm portion 28 each having contact portions 27 </ b> B and 28 </ b> B are provided on the upper arm portion 21.
