Description

本発明は、雄コネクタと雌コネクタで構成されるコネクタセットに関する。 The present invention relates to a connector set including a male connector and a female connector.

自動車において電気デバイス同士を電気的に接続するコネクタは家庭用のコネクタと異なり、厳しい環境で使われる。厳しい環境の要件としては、車両の振動や熱変化が挙げられる。車両の振動により、雄コネクタの端子と雌コネクタの端子が長期間に亘って摺動する虞がある。また、熱変化によりコネクタ自体が熱変形することによっても端子同士が摺動する虞がある。さらに、コネクタの熱変形によりコネクタ間の結合が緩み、走行振動による摺動が助長される虞もある。長期間にわたり摺動が続くと端子が磨滅し、電気的接続状態が低下する虞がある。また、摺動が過度に続くと端子のメッキがはがれ、端子の表面に酸化物が生成されることもあり得る。酸化物は電気抵抗を増大させる。 Unlike automobile connectors, connectors for electrically connecting electrical devices in automobiles are used in harsh environments. Severe environmental requirements include vehicle vibration and thermal changes. Due to the vibration of the vehicle, the terminals of the male connector and the female connector may slide over a long period of time. In addition, the terminals may slide due to thermal deformation of the connector itself due to thermal changes. Furthermore, there is a possibility that the coupling between the connectors is loosened due to thermal deformation of the connectors, and sliding due to running vibration is promoted. If sliding continues for a long period of time, the terminals may be worn out and the electrical connection state may be lowered. Further, if the sliding continues excessively, the terminal plating may be peeled off, and an oxide may be generated on the surface of the terminal. Oxides increase electrical resistance.

そこで、コネクタの端子の摺動を抑制する技術の一例が特許文献１に開示されている。特許文献１の技術は、コネクタの幅方向と上下方向（即ち、コネクタの矩形状の挿通口における、横方向と縦方向）の摺動を抑制することを目的とする。特許文献１が開示する技術は、雌コネクタに備えた板バネが雄コネクタの端子の両サイドを支持することでコネクタの幅方向における摺動を抑制し、また、雄コネクタが、板バネと、板バネと対向している突出部とにより上下方向に挟持保持されることでコネクタの上下方向における摺動を抑制する。 An example of a technique for suppressing the sliding of the connector terminals is disclosed in Patent Document 1. The technique of patent document 1 aims at suppressing the sliding of the width direction of a connector, and an up-down direction (namely, the horizontal direction and the vertical direction in the rectangular insertion port of a connector). The technology disclosed in Patent Document 1 is that the leaf spring provided in the female connector supports both sides of the terminal of the male connector to suppress sliding in the width direction of the connector, and the male connector includes the leaf spring, The connector is prevented from sliding in the vertical direction by being sandwiched and held in the vertical direction by the projecting portion facing the leaf spring.

特許文献１の技術は、コネクタの幅方向及び上下方向の摺動は抑制できるが、雄コネクタの挿通・抜去方向（以下、「挿抜方向」とも称する）における摺動抑制は配慮されていない。本明細書は、コネクタの挿抜方向における摺動を効果的に抑制する技術を提供する。 The technology of Patent Document 1 can suppress sliding in the width direction and vertical direction of the connector, but does not consider the suppression of sliding in the insertion / removal direction of the male connector (hereinafter also referred to as “insertion / removal direction”). The present specification provides a technique for effectively suppressing sliding in a connector insertion / extraction direction.

本明細書が開示する技術の一態様は次の構成を有するコネクタセットに具現化することができる。そのコネクタセットは、筒状の嵌合部を有する雌コネクタと、嵌合部に挿通される平板端子を有する雄コネクタで構成される。雌コネクタは、雄コネクタを抜け止めするための板部材を備える。その板部材は、挿通された平板端子と嵌合部内面との間に位置するように雌コネクタに取り付けられている。板部材には、平行に並んだ複数の切込みが設けられている。板部材は、切込みに沿って板部材の一面側に立ち上がる複数の第１折り曲げ部と、他面側に立ち上がる複数の第２折り曲げ部を有する。第１折り曲げ部は、第１折り曲げ部と板部材の平面とが嵌合部の奥側で鋭角を成すように折り曲げられ、その先端エッジが挿通された平板端子と接触する。第２折り曲げ部は、第２折り曲げ部と板部材の平面とが嵌合部の入口側で鋭角を成すように折り曲げられ、その先端エッジが嵌合部内面と接触する。 One aspect of the technology disclosed in this specification can be embodied in a connector set having the following configuration. The connector set includes a female connector having a cylindrical fitting portion and a male connector having a flat terminal inserted through the fitting portion. The female connector includes a plate member for retaining the male connector. The plate member is attached to the female connector so as to be positioned between the inserted flat plate terminal and the inner surface of the fitting portion. The plate member is provided with a plurality of cuts arranged in parallel. The plate member has a plurality of first bent portions that rise to one surface side of the plate member along the cut and a plurality of second bent portions that stand to the other surface side. The first bent portion is bent so that the first bent portion and the flat surface of the plate member form an acute angle on the back side of the fitting portion, and comes into contact with the flat plate terminal through which the leading edge is inserted. The second bent portion is bent so that the second bent portion and the flat surface of the plate member form an acute angle on the inlet side of the fitting portion, and the leading edge thereof contacts the fitting portion inner surface.

雄コネクタの平板端子が雌コネクタの嵌合部に挿通されることで、コネクタセットは電気的に接続される。雌コネクタには、金属製の板部材が、平板端子と嵌合部内面との間に位置するように取り付けられている。板部材は、例えば圧入によって雌コネクタに取り付けられる。板部材には、典型的には板バネが用いられる。板部材は平行に並んだ複数の切込みを有する。切込みは、例えばコの字状に設けられ、切込みに沿って折り曲げられて立ち上げられる。複数の折り曲げ部のうち、いくつかは板部材の一面側に立ち上がるように折り曲げられ、残りは板部材の他面側に立ち上がるように折り曲げられる。便宜上、前者を第１折り曲げ部と称し、後者を第２折り曲げ部と称する。別言すれば、第１折り曲げ部は、板部材に対して平板端子側に折り曲げられ、第２折り曲げ部は、板部材に対して嵌合部内面側に折り曲げられる。第１折り曲げ部は、第１折り曲げ部と板部材の平面とが嵌合部の奥側で鋭角を成すように折り曲げられて、第１折り曲げ部の先端エッジが、挿通された雄コネクタの平板端子と接触する。第２折り曲げ部は、第２折り曲げ部と板部材の平面とが嵌合部の入口側で鋭角を成すように折り曲げられて、第２折り曲げ部の先端エッジが、嵌合部内面と接触する。第１折り曲げ部、第２折り曲げ部はいずれも、折り曲げ部の角度が上記した条件に合致していればよく、嵌合部の奥側から入口側に折り曲げられてもよいし、嵌合部の入口側から奥側に折り曲げられてもよい。 The connector set is electrically connected by inserting the flat terminal of the male connector into the fitting portion of the female connector. A metal plate member is attached to the female connector so as to be positioned between the flat plate terminal and the fitting portion inner surface. The plate member is attached to the female connector, for example, by press fitting. A plate spring is typically used as the plate member. The plate member has a plurality of cuts arranged in parallel. The cut is provided, for example, in a U-shape, and is bent up along the cut to be raised. Among the plurality of bent portions, some are bent so as to stand up on one side of the plate member, and the rest are bent so as to stand up on the other side of the plate member. For convenience, the former is referred to as a first bent portion, and the latter is referred to as a second bent portion. In other words, the first bent portion is bent toward the flat plate terminal with respect to the plate member, and the second bent portion is bent toward the fitting portion inner surface side with respect to the plate member. The first bent portion is bent so that the first bent portion and the flat surface of the plate member form an acute angle on the back side of the fitting portion, and the front edge of the first bent portion is inserted into the flat terminal of the male connector Contact with. The second bent portion is bent so that the second bent portion and the flat surface of the plate member form an acute angle on the inlet side of the fitting portion, and the leading edge of the second bent portion comes into contact with the inner surface of the fitting portion. The first bent portion and the second bent portion may both be bent from the rear side of the fitting portion to the inlet side as long as the angle of the bent portion matches the above-described conditions. It may be bent from the entrance side to the back side.

この構成によると、雄コネクタ（の平板端子）と第１折り曲げ部とが嵌合部入口側で成す角度が鋭角である。そのような構造によって、雄コネクタは差し込み易いが抜き難くなる。別言すれば、雄コネクタを抜去する際の平板端子と板部材先端エッジの間の摩擦力が、雄コネクタを挿通する際の平板端子と先端エッジの間の摩擦力よりも大きくなる。一方において、雌コネクタ（の嵌合部内面）と第２折り曲げ部とが嵌合部奥側で成す角度も鋭角である。そのような構造によって、雄コネクタを抜去する際の嵌合部内面と板部材先端エッジの間の摩擦力が、雄コネクタを挿通する際の嵌合部内面と先端エッジの間の摩擦力よりも大きくなる。即ち、板部材が雄コネクタ抜去方向に外れ難くなる。上記の構造の板部材により、挿通された雄コネクタが抜去方向に後退し難くなる。雄コネクタを嵌合部の最も奥まで挿通すると（即ち、それ以上は奥へ進まなくなるまで雄コネクタを挿通すると）、雄コネクタはそれ以上は前進することがなく、また、板部材によって後退もし難くなる。即ち、雄コネクタの挿抜方向の摺動を抑制できる。 According to this configuration, the angle formed by the male connector (the flat plate terminal thereof) and the first bent portion on the fitting portion entrance side is an acute angle. Such a structure makes the male connector easy to insert but difficult to remove. In other words, the frictional force between the flat plate terminal and the plate member tip edge when the male connector is pulled out becomes larger than the friction force between the flat plate terminal and the tip edge when the male connector is inserted. On the other hand, the angle formed by the female connector (the inner surface of the fitting portion) and the second bent portion on the back side of the fitting portion is also an acute angle. With such a structure, the frictional force between the inner surface of the mating portion and the leading edge of the plate member when the male connector is removed is greater than the frictional force between the inner surface of the mating portion and the leading edge when the male connector is inserted. growing. That is, it becomes difficult for the plate member to come off in the male connector removal direction. The plate member having the above structure makes it difficult for the inserted male connector to retract in the removal direction. When the male connector is inserted all the way into the fitting part (that is, when the male connector is inserted until the male connector does not advance further), the male connector does not advance further, and it is difficult for the plate member to retract. Become. That is, sliding in the insertion / extraction direction of the male connector can be suppressed.

本明細書が開示する技術の詳細、及び、さらなる改良は、発明の実施の形態、及び、実施例にて詳しく説明する。 Details of the technology disclosed in this specification and further improvements will be described in detail in embodiments and examples of the invention.

実施例の特徴の幾つかを最初に列記する。なお、以下の特徴は、それぞれ単独でも有用なものである。 Some of the features of the examples are listed first. In addition, the following features are each useful by itself.

（特徴１）雌コネクタを板部材の平面に対して直交方向から平面視したときに、第１折り曲げ部及び第２折り曲げ部の折り曲げ線が、雄コネクタの挿通方向に対して斜めである。この構成によると、雄コネクタの抜去方向の摺動が抑制できるとともに、雄コネクタの幅方向における摺動も抑制できる。 (Feature 1) When the female connector is planarly viewed from the direction orthogonal to the plane of the plate member, the fold lines of the first bent portion and the second bent portion are oblique with respect to the insertion direction of the male connector. According to this configuration, sliding in the removal direction of the male connector can be suppressed, and sliding in the width direction of the male connector can also be suppressed.

（特徴２）雄コネクタと雌コネクタのいずれか一方に雄コネクタの挿通を止める制止部が設けられている。制止部があることにより、雄コネクタは、制止部によって予め定められた位置よりも奥に挿通されることがない。 (Feature 2) A restraining portion for stopping insertion of the male connector is provided in one of the male connector and the female connector. Due to the presence of the restraining portion, the male connector is not inserted deeper than the position predetermined by the restraining portion.

図面を参照して第１実施例のコネクタセットについて説明する。図１（Ａ）はコネクタセット１０の挿抜方向における断面図（図１（Ｂ）のＡ−Ａ線における断面）を示す。図１（Ｂ）はコネクタセット１０の幅方向における断面図（図１（Ａ）のＢ−Ｂ線における断面）を示す。コネクタセット１０は、雄コネクタ２と雌コネクタ４からなる。雌コネクタ４は、金属製の筒状の嵌合部２０を有する。嵌合部２０が、雌コネクタ側の端子に相当する。嵌合部２０の内部には、板バネ６が取り付けられている（後述）。他方、雄コネクタ２は、金属製の平板端子３を有する。雄コネクタ２、及び、雌コネクタ４は、いずれも、端子（平板端子３、嵌合部２０）の一部を覆う樹脂製のカバーを有するが、それらの図示は省略している。雄コネクタ２の平板端子３を雌コネクタ４の嵌合部２０に挿通することにより、コネクタセット１０は電気的に接続される。雌コネクタ４はさらに、制止部１４を有する。雄コネクタ２の平板端子３を嵌合部２０に挿通していくと、平板端子３は制止部１４に当接し、それ以上進めなくなる。即ち、制止部１４は、雄コネクタ２の挿通を予め定められた位置で止め、雄コネクタ２をそれ以上奥に挿通することを防止する。なお、図中のＹ軸の方向が挿抜方向に相当する。 The connector set of the first embodiment will be described with reference to the drawings. FIG. 1A shows a cross-sectional view in the insertion / extraction direction of the connector set 10 (cross section taken along the line AA in FIG. 1B). FIG. 1B shows a cross-sectional view in the width direction of the connector set 10 (a cross section taken along line BB in FIG. 1A). The connector set 10 includes a male connector 2 and a female connector 4. The female connector 4 has a metal cylindrical fitting portion 20. The fitting portion 20 corresponds to a terminal on the female connector side. A leaf spring 6 is attached inside the fitting portion 20 (described later). On the other hand, the male connector 2 has a flat plate terminal 3 made of metal. Each of the male connector 2 and the female connector 4 has a resin cover that covers a part of the terminals (the flat terminal 3 and the fitting portion 20), but the illustration thereof is omitted. The connector set 10 is electrically connected by inserting the flat plate terminal 3 of the male connector 2 into the fitting portion 20 of the female connector 4. The female connector 4 further has a restraining portion 14. When the flat plate terminal 3 of the male connector 2 is inserted through the fitting portion 20, the flat plate terminal 3 comes into contact with the stop portion 14 and cannot be further advanced. That is, the restraining part 14 stops the insertion of the male connector 2 at a predetermined position and prevents the male connector 2 from being inserted further into the back. Note that the direction of the Y-axis in the figure corresponds to the insertion / extraction direction.

前述の通り、雌コネクタ４は、その嵌合部２０の内部に、金属性の板バネ６を備える。図２、図３を参照して、板バネ６について説明する。図２は、板バネ６の平面図である。図２に示すように、板バネ６には、コの字状の切込みが設けられている。本実施例の板バネ６は、Ｙ軸方向に沿って４つ、Ｘ軸方向に沿って３つ、計１２個の切込みを有する。以下では、説明の都合上、Ｙ軸方向に沿って設けられる切込みを、Ｘ軸の正方向に向かって、順に１列目、２列目、３列目と称する。１列目の４つの切込みは平行に並んでおり、２列目、３列目の切込みについても同様である。２列目の切込み６ｘは、Ｙ軸の負方向が閉じられたコの字型に切込まれており、他方、１列目の切込み６ｙ及び３列目の切込み６ｙは、Ｙ軸の正方向が閉じられた逆コの字型に切込まれている。図２の板バネ６に付された○印は、切込み６ｘに沿って紙面の裏側から表側に折り曲げることを意味し、×印は、切込み６ｙに沿って紙面の表側から裏側に折り曲げることを意味する。そのようにして折り曲げられた板バネ６を、図３に示す。図３は、板バネ６の斜視図である。２列目の切込み６ｘに沿って折り曲げると、第１折り曲げ部６ａが立ち上がり、１列目と３列目の切込み６ｙに沿って折り曲げると、第２折り曲げ部６ｂが立ち上がる。即ち、第１折り曲げ部６ａと第２折り曲げ部６ｂは板バネ６の平面に対して、相互に反対側に折り曲げられる。第１折り曲げ部６ａにおいて、その折り曲げ線と平行な辺を、先端エッジ６ａｅと称し、第２折り曲げ部６ｂにおいて、その折り曲げ線と平行な辺を、先端エッジ６ｂｅと称する。 As described above, the female connector 4 includes the metal leaf spring 6 inside the fitting portion 20. The leaf spring 6 will be described with reference to FIGS. FIG. 2 is a plan view of the leaf spring 6. As shown in FIG. 2, the leaf spring 6 is provided with a U-shaped cut. The leaf spring 6 of this embodiment has a total of 12 cuts, four along the Y-axis direction and three along the X-axis direction. Hereinafter, for convenience of explanation, the cuts provided along the Y-axis direction are referred to as the first, second, and third rows in order toward the positive direction of the X-axis. The four cuts in the first row are arranged in parallel, and the same applies to the cuts in the second row and the third row. The second row of cuts 6x are cut in a U-shape with the negative Y-axis direction closed, while the first row of cuts 6y and the third row of cuts 6y are in the positive direction of the Y-axis. Is cut into a closed inverted U-shape. The symbol “◯” attached to the leaf spring 6 in FIG. 2 means that the sheet is folded from the back side to the front side along the notch 6x, and the sign “X” means that the sheet is folded from the front side to the back side of the sheet along the notch 6y. To do. FIG. 3 shows the leaf spring 6 bent in such a manner. FIG. 3 is a perspective view of the leaf spring 6. When bent along the second row of cuts 6x, the first bent portion 6a rises, and when bent along the first row and third row of cuts 6y, the second bent portion 6b rises. That is, the first bent portion 6 a and the second bent portion 6 b are bent to the opposite sides with respect to the plane of the leaf spring 6. In the first bent portion 6a, a side parallel to the fold line is referred to as a leading edge 6ae, and in the second bent portion 6b, a side parallel to the fold line is referred to as a leading edge 6be.

図１に戻り、嵌合部２０内部の板バネ６について説明する。板バネ６は、雄コネクタ２を雌コネクタ４に挿通した際に、平板端子３と嵌合部２０の内面との間に位置するように取り付けられる。本実施例では、図３の板バネ６は嵌合部２０に圧入されて固定される。具体的には、板バネ６のＸ軸方向における両端が、嵌合部２０の内面に固着する。なお、板バネ６の取り付け方法は、これに限られない。 Returning to FIG. 1, the leaf spring 6 inside the fitting portion 20 will be described. The leaf spring 6 is attached so as to be positioned between the flat terminal 3 and the inner surface of the fitting portion 20 when the male connector 2 is inserted into the female connector 4. In this embodiment, the leaf spring 6 in FIG. 3 is press-fitted into the fitting portion 20 and fixed. Specifically, both ends of the leaf spring 6 in the X-axis direction are fixed to the inner surface of the fitting portion 20. In addition, the attachment method of the leaf | plate spring 6 is not restricted to this.

第１折り曲げ部６ａは、図１（Ａ）に示すように、第１折り曲げ部６ａと板バネ６の平面とが、嵌合部２０の奥側（即ち、Ｙ軸の正方向側）で鋭角を成すように折り曲げられる。また、第１折り曲げ部６ａは、平板端子３を嵌合部２０に挿通した際に、先端エッジ６ａｅが平板端子３と接触するように折り曲げられる。他方、第２折り曲げ部６ｂは、図１（Ａ）に示すように、第２折り曲げ部６ｂと板バネ６の平面とが、嵌合部２０の入口側（即ち、Ｙ軸の負方向側）で鋭角を成すように折り曲げられる。また、第２折り曲げ部６ｂは、先端エッジ６ｂｅが嵌合部２０の内面と接触するように折り曲げられる。 As shown in FIG. 1A, the first bent portion 6a has an acute angle between the first bent portion 6a and the flat surface of the leaf spring 6 on the back side of the fitting portion 20 (that is, the Y axis positive direction side). It can be folded to form Further, the first bent portion 6 a is bent so that the tip edge 6 ae contacts the flat plate terminal 3 when the flat plate terminal 3 is inserted into the fitting portion 20. On the other hand, as shown in FIG. 1A, the second bent portion 6b is such that the second bent portion 6b and the flat surface of the leaf spring 6 are the inlet side of the fitting portion 20 (that is, the negative direction side of the Y axis). It can be bent at an acute angle. The second bent portion 6b is bent so that the tip edge 6be is in contact with the inner surface of the fitting portion 20.

第１実施例のコネクタセット１０の利点を説明する。第１実施例の板バネ６の第１折り曲げ部６ａは、平板端子３と、嵌合部２０の入口側で鋭角を成す。そのような構造により、雄コネクタ２を抜去する際の平板端子３と、第１折り曲げ部６ａの先端エッジ６ａｅの間の摩擦力Ｆｍｏ（即ち、雄コネクタ２を抜去する際に雄コネクタ２にかかる摩擦力）は、雄コネクタ２を挿通する際の平板端子３と先端エッジ６ａｅの間の摩擦力Ｆｍｉ（即ち、雄コネクタ２を挿通する際に雄コネクタ２にかかる摩擦力）よりも大きくなる。即ち、雄コネクタ２は雌コネクタ４に差し込み易くなるとともに、抜き難くなる。一方において、第２折り曲げ部６ｂは、嵌合部２０の内面と、嵌合部２０の奥側で鋭角を成す。そのような構造により、雄コネクタ２を抜去する際の嵌合部２０内面と、第２折り曲げ部６ｂの先端エッジ６ｂｅの間の摩擦力Ｆｆｏ（即ち、雄コネクタ２を抜去する際に雌コネクタ４にかかる摩擦力）は、雄コネクタ２を挿通する際の嵌合部２０内面と先端エッジ６ｂｅの間の摩擦力Ｆｆｉ（即ち、雄コネクタ２を挿通する際に雌コネクタ４にかかる摩擦力）よりも大きくなる。即ち、板バネ６は、雌コネクタ４に対して、雄コネクタ２の抜去方向に動き難くなる。板バネ６が上記のような第１折り曲げ部６ａ及び第２折り曲げ部６ｂを有することにより、雄コネクタ２は一旦雌コネクタ４に挿通されると抜去し難くなる。また、雌コネクタ４は、制止部１４を有する。従って、雄コネクタ２を嵌合部２０に挿通していくと、平板端子３は制止部１４に当接し、それ以上前に進めなくなる。即ち、本実施例における雄コネクタ２は、板バネ６によって抜去方向に動き難くなるとともに、制止部１４によって挿通方向にも動き難くなる。上記の構造により雄コネクタ２の挿抜方向の摺動を抑制できる。車両の振動やコネクタセットの熱変形に起因して、雄コネクタが挿抜方向に摺動することを抑制できる。自動車のような厳しい環境下で用いられる場合においても、自動車に搭載される電気デバイス同士を適切に接続できる。 The advantages of the connector set 10 of the first embodiment will be described. The first bent portion 6 a of the leaf spring 6 of the first embodiment forms an acute angle with the flat terminal 3 and the inlet side of the fitting portion 20. With such a structure, the frictional force Fmo between the flat terminal 3 when the male connector 2 is removed and the tip edge 6ae of the first bent portion 6a (that is, the male connector 2 is applied when the male connector 2 is removed). (Friction force) is larger than the friction force Fmi between the flat terminal 3 and the tip edge 6ae when the male connector 2 is inserted (that is, the friction force applied to the male connector 2 when the male connector 2 is inserted). That is, the male connector 2 is easily inserted into the female connector 4 and is difficult to remove. On the other hand, the second bent portion 6 b forms an acute angle with the inner surface of the fitting portion 20 and the back side of the fitting portion 20. With such a structure, the frictional force Ffo between the inner surface of the fitting portion 20 when the male connector 2 is removed and the tip edge 6be of the second bent portion 6b (that is, the female connector 4 when removing the male connector 2). Is a frictional force Ffi between the inner surface of the fitting portion 20 when the male connector 2 is inserted and the front edge 6be (that is, a frictional force applied to the female connector 4 when the male connector 2 is inserted). Also grows. That is, the leaf spring 6 is difficult to move in the direction of removing the male connector 2 with respect to the female connector 4. Since the leaf spring 6 has the first bent portion 6 a and the second bent portion 6 b as described above, the male connector 2 is difficult to be removed once inserted into the female connector 4. The female connector 4 has a restraining portion 14. Therefore, as the male connector 2 is inserted through the fitting portion 20, the flat terminal 3 comes into contact with the restraining portion 14 and cannot move forward any further. That is, the male connector 2 in this embodiment is difficult to move in the removal direction by the leaf spring 6 and is also difficult to move in the insertion direction by the restraining portion 14. With the above structure, sliding in the insertion / extraction direction of the male connector 2 can be suppressed. It can suppress that a male connector slides in the insertion / extraction direction resulting from the vibration of a vehicle, or the thermal deformation of a connector set. Even when used in a harsh environment such as an automobile, electrical devices mounted on the automobile can be appropriately connected.

次に、図４〜図６を参照して、第２実施例について説明する。本実施例では、第１実施例と同じ機能を有する部材には同じ符号を付し、その説明を省略する。 Next, a second embodiment will be described with reference to FIGS. In the present embodiment, members having the same functions as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

第２実施例のコネクタセット１０ａは、板バネに設けられる折り曲げ部の形状が第１実施例の場合と異なる。図４は、第２実施例の板バネ２６の平面図である。板バネ２６には、図４に示すような３つの切込み２６ｚ１〜２６ｚ３が平行に設けられている。各切込みは、３つの台形が連続する形で切込まれている。より具体的には、Ｘ軸方向に隣接する各台形はその脚を共有しており、各台形は、台形の下底以外の３辺が切り込まれている。また、隣接する切込み間の距離は、台形の高さに等しい。即ち、Ｙ軸方向に隣接する２つの台形において、一方の台形の下底の一部と、他方の台形の上底は重なっている。以下では、説明の都合上、Ｙ軸方向に沿って設けられる台形状の切込みを、Ｘ軸の正方向に向かって、順に１列目、２列目、３列目と称する。図２と同様に、板バネ２６に付された○印は、切込みに沿って、２列目の台形状の部分を紙面の裏側から表側に折り曲げることを意味し、×印は、切込みに沿って１列目及び３列目の台形状の部分を紙面の表側から裏側に折り曲げることを意味する。 The connector set 10a of the second embodiment is different from the first embodiment in the shape of the bent portion provided on the leaf spring. FIG. 4 is a plan view of the leaf spring 26 of the second embodiment. The plate spring 26 is provided with three cuts 26z1 to 26z3 in parallel as shown in FIG. Each incision is inscribed in a form in which three trapezoids are continuous. More specifically, each trapezoid adjacent in the X-axis direction shares its leg, and each side of the trapezoid is cut out at three sides other than the bottom base of the trapezoid. The distance between adjacent cuts is equal to the height of the trapezoid. That is, in two trapezoids adjacent in the Y-axis direction, a part of the lower base of one trapezoid and the upper base of the other trapezoid overlap. Hereinafter, for convenience of explanation, the trapezoidal cuts provided along the Y-axis direction are sequentially referred to as the first, second, and third columns in the positive direction of the X-axis. As in FIG. 2, the circle mark attached to the leaf spring 26 means that the trapezoidal portion of the second row is bent from the back side to the front side along the notch, and the x mark is along the notch. This means that the trapezoidal portions in the first and third rows are bent from the front side to the back side of the paper.

線Ｌ１は、切込みに沿って板バネ２６を折り曲げる折り曲げ線の１つである。折り曲げ線Ｌ１と、その両側の切り込み２６ｚ１及び２６ｚ２に関し、折り曲げ部を説明する。符号２６ａを付した第１折り曲げ部と、符号２６ｂを付した第２折り曲げ部２６ｂは、切込み２６ｚ１と２６ｚ２に挟まれ、結局、図４の符号Ｌｐが示す部分だけで板バネ２６の枠部分と繋がっている。従って、第２折り曲げ部２６ｂを符号Ｌｐが示す部分で紙面裏側へ折り曲げると、第１折り曲げ部２６ａが従動的に紙面の表側に立ち上がる。図４に示す板バネ２６は、相互に反対方向に立ち上がる第１及び第２折り曲げ部を作成する工程が簡単になるという利点を奏する。この利点を有する板バネの特徴は以下の通り表現できる。即ち、板バネ２６は、折り曲げ線Ｌ１を境界にその一方の側に設けられた第１切込み２６ｚ２と他方の側に設けられた第２切込み２６ｚ１を有する。第１切込み２６ｚ２と折り曲げ線Ｌ１で囲まれた部分が第１折り曲げ部２６ａに相当し、第２切込み２６ｚ１と折り曲げ線Ｌ１で囲まれた部分が第２折り曲げ部２６ｂに相当する。第１折り曲げ部２６ａにおいて折り曲げ線Ｌ１に相当する辺は、第２折り曲げ部２６ｂと繋がっているか、あるいは、他の切込みによって板バネ２６の枠部分とは切り離されている。上記の形状を有する切込みを設けることによって、第２折り曲げ部２６ｂを紙面の一方側へ折り曲げると第１折り曲げ部２６ａが従動的に紙面他方側に立ち上がることになる。即ち、第１折り曲げ部２６ａと第２折り曲げ部２６ｂは、板バネ２６の平面に対して、反対側に折り曲げられる。 The line L1 is one of folding lines that bend the leaf spring 26 along the cut. Regarding the fold line L1 and the cuts 26z1 and 26z2 on both sides thereof, the fold portion will be described. The first bent portion 26a and the second bent portion 26b 26b are sandwiched between the notches 26z1 and 26z2, and only the portion indicated by the symbol Lp in FIG. It is connected. Therefore, when the second bent portion 26b is bent to the back side of the paper at the portion indicated by the symbol Lp, the first bent portion 26a is erected on the front side of the paper surface. The leaf spring 26 shown in FIG. 4 has the advantage that the process of creating the first and second bent portions that rise in opposite directions is simplified. The characteristics of the leaf spring having this advantage can be expressed as follows. That is, the leaf spring 26 has a first cut 26z2 provided on one side of the folding line L1 and a second cut 26z1 provided on the other side. A portion surrounded by the first cut 26z2 and the folding line L1 corresponds to the first bent portion 26a, and a portion surrounded by the second cut 26z1 and the bent line L1 corresponds to the second bent portion 26b. The side corresponding to the fold line L1 in the first bent portion 26a is connected to the second bent portion 26b, or is separated from the frame portion of the leaf spring 26 by another cut. By providing the cut having the above-described shape, when the second bent portion 26b is bent to one side of the paper surface, the first bent portion 26a is erected on the other side of the paper surface. That is, the first bent portion 26 a and the second bent portion 26 b are bent to the opposite side with respect to the plane of the leaf spring 26.

その他の折り曲げ線についても同様に折り曲げた板バネ２６を、図５に示す。第１折り曲げ部２６ａにおいて、その折り曲げ線と平行な辺を、先端エッジ２６ａｅと称し、第２折り曲げ部２６ｂにおいて、その折り曲げ線と平行な辺を、先端エッジ２６ｂｅと称する。 FIG. 5 shows a leaf spring 26 that is similarly bent with respect to other folding lines. In the first bent portion 26a, a side parallel to the fold line is referred to as a leading edge 26ae, and in the second bent portion 26b, a side parallel to the fold line is referred to as a leading edge 26be.

続いて、図６を参照して、嵌合部２０内部の板バネ２６について説明する。図６（Ａ）は本実施例のコネクタセット１０ａの挿抜方向における断面図（図６（Ｂ）のＡ−Ａ線における断面）を示す。図６（Ｂ）はコネクタセット１０ａの幅方向における断面図（図６（Ａ）のＢ−Ｂ線における断面）を示す。図４に示すように、第１折り曲げ部２６ａの折り曲げ線と、第２折り曲げ部２６ｂの折り曲げ線は直線Ｌ１で共通であるため、板バネ２６をＸ軸方向からみると（図６（Ａ）参照）、第１折り曲げ部２６ａと第２折り曲げ部２６ｂは一直線に見える。その他の特徴は第１実施例の場合と同じである。 Next, the leaf spring 26 inside the fitting portion 20 will be described with reference to FIG. FIG. 6A is a cross-sectional view in the insertion / extraction direction of the connector set 10a of the present embodiment (cross section taken along line AA in FIG. 6B). FIG. 6B shows a cross-sectional view in the width direction of the connector set 10a (cross section taken along line BB in FIG. 6A). As shown in FIG. 4, since the fold line of the first fold portion 26a and the fold line of the second fold portion 26b are common to the straight line L1, the leaf spring 26 is viewed from the X-axis direction (FIG. 6A). See), the first bent portion 26a and the second bent portion 26b appear to be in a straight line. Other features are the same as in the first embodiment.

第２実施例のコネクタセット１０ａは、第１実施例のコネクタセット１０の利点に加えて次の利点を有する。前述したように、第２折り曲げ部２６ｂを板バネ２６の一方面側へ折り曲げると第１折り曲げ部２６ａが従動的に反対側に立ち上がる。それゆえ、第２実施例のコネクタセット１０ａは、製造コストを抑制することができる。また、隣接する切込み２６ｚの間の距離が、第１折り曲げ部２６ａ及び第２折り曲げ部２６ｂの高さに等しい。即ち、隣接する切込み２６ｚの間の板バネ２６は、全て第１折り曲げ部２６ａあるいは第２折り曲げ部２６ｂとして用いられる。従って、板バネ２６から効率的に第１折り曲げ部２６ａ及び第２折り曲げ部２６ｂを形成できる。 The connector set 10a of the second embodiment has the following advantages in addition to the advantages of the connector set 10 of the first embodiment. As described above, when the second bent portion 26b is bent toward the one surface side of the leaf spring 26, the first bent portion 26a rises to the opposite side. Therefore, the connector set 10a of the second embodiment can reduce the manufacturing cost. Further, the distance between the adjacent cuts 26z is equal to the height of the first bent portion 26a and the second bent portion 26b. That is, the leaf springs 26 between the adjacent cuts 26z are all used as the first bent portion 26a or the second bent portion 26b. Therefore, the first bent portion 26a and the second bent portion 26b can be efficiently formed from the leaf spring 26.

図７、図８を参照して、第３実施例における板バネ３６について説明する。本実施例では、第１実施例と同じ機能を有する部材には同じ符号を付し、その説明を省略する。 The leaf spring 36 in the third embodiment will be described with reference to FIGS. In the present embodiment, members having the same functions as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

第３実施例のコネクタセット１０ｂも、板バネに設けられる折り曲げ部の形状が第１実施例の場合と異なる。図７に示す板バネ３６は、図４の板バネ２６が有する切込みと形状は同じであるが、角度が異なる切込み３６ｚを有する。図７と図８は、板バネ４６をその平面に対して直交方向からみたときの図に相当する。第３実施例のコネクタセット１０ｂでは、第１及び第２折り曲げ部の折り曲げ線Ｌ２が、雄コネクタ２の挿抜方向（図中のＹ軸方向）に対して斜めである。即ち、板バネ３６には、折り曲げ線Ｌ２がＹ軸に対して斜めとなるように切込みが設けられる。 The connector set 10b of the third embodiment is also different from the first embodiment in the shape of the bent portion provided on the leaf spring. The leaf spring 36 shown in FIG. 7 has the same notch shape as that of the leaf spring 26 of FIG. 4, but has a notch 36z having a different angle. 7 and 8 correspond to views when the leaf spring 46 is viewed from a direction orthogonal to the plane. In the connector set 10b of the third embodiment, the fold line L2 of the first and second bent portions is oblique with respect to the insertion / extraction direction of the male connector 2 (Y-axis direction in the drawing). That is, the leaf spring 36 is provided with a cut so that the bending line L2 is oblique to the Y axis.

第３実施例における板バネ３６の上記特徴は、より詳しくは次のように表現することもできる。第１折り曲げ部３６ａの先端エッジ３６ａｅから嵌合部奥側（即ち、Ｙ軸の正方向側）へ延びる法線をＮ１とする。また、第２折り曲げ部３６ｂの先端エッジ３６ｂｅから嵌合部入口側（即ち、Ｙ軸の負方向側）へ延びる法線をＮ２とする。板バネ３６では、法線Ｎ１と雄コネクタ２の挿通方向Ｄ１が鋭角Ａ１を成すように、そして、法線Ｎ２と雄コネクタ２の抜去方向Ｄ２が鋭角Ａ２を成すように、切込みが設けられる。 More specifically, the above feature of the leaf spring 36 in the third embodiment can be expressed as follows. A normal line extending from the tip edge 36ae of the first bent portion 36a to the fitting portion back side (that is, the positive direction side of the Y axis) is N1. Further, a normal line extending from the tip edge 36be of the second bent portion 36b to the fitting portion inlet side (that is, the negative direction side of the Y axis) is N2. The leaf spring 36 is provided with a cut so that the normal line N1 and the insertion direction D1 of the male connector 2 form an acute angle A1, and the normal line N2 and the removal direction D2 of the male connector 2 form an acute angle A2.

図８は、そのような板バネ３６が取り付けられた雌コネクタ４に雄コネクタ２が挿通されたコネクタセット１０ｂの平面図である。なお、図を見易くするために、雄コネクタ２に関してＸ軸の正方向側の嵌合部２０は、図示を省略している。本実施例においても、第１、第２実施例と同様に、第１折り曲げ部３６ａは折り曲げ線（例えば線Ｌ２）で紙面の裏側から表側に、第２折り曲げ部３６ｂは折り曲げ線で紙面の表側から裏側に折り曲げられる。また、第１折り曲げ部３６ａと板バネ３６の平面は、嵌合部奥側で鋭角を成すように折り曲げられ、先端エッジ３６ａｅは平板端子３に接触する。他方、第２折り曲げ部３６ｂと板バネ３６の平面は、嵌合部入口側で鋭角を成すように折り曲げられ、先端エッジ３６ｂｅは嵌合部２０内面に接触する。 FIG. 8 is a plan view of a connector set 10b in which the male connector 2 is inserted into the female connector 4 to which such a leaf spring 36 is attached. In order to make the drawing easier to see, the illustration of the fitting portion 20 on the positive side of the X axis with respect to the male connector 2 is omitted. Also in this embodiment, as in the first and second embodiments, the first fold portion 36a is a fold line (for example, line L2) from the back side of the paper surface to the front side, and the second fold portion 36b is the fold line and the front side of the paper surface. It is folded from the back side. The planes of the first bent portion 36 a and the leaf spring 36 are bent so as to form an acute angle on the rear side of the fitting portion, and the leading edge 36 ae contacts the flat plate terminal 3. On the other hand, the planes of the second bent portion 36b and the leaf spring 36 are bent so as to form an acute angle on the fitting portion inlet side, and the tip edge 36be contacts the inner surface of the fitting portion 20.

本実施例のコネクタセット１０ｂの利点を説明する。本実施例の第１折り曲げ部３６ａは、雄コネクタ２の挿抜方向（即ち、図８のＹ軸方向）において、平板端子３と嵌合部入口側で鋭角を成し、第２折り曲げ部３６ｂは、嵌合部２０の内面と嵌合部奥側で鋭角を成す。従って、第１、第２実施例と同様に、Ｆｍｏ＞Ｆｍｉ、及びＦｆｏ＞Ｆｆｉの関係が成り立つため、雄コネクタ２を一旦嵌合部２０に挿通したら、抜去し難くなる。従って、、コネクタセット１０ｂは、第１実施例のコネクタセット１０と同様に雄コネクタ２の挿抜方向における摺動を抑制できる。 The advantages of the connector set 10b of this embodiment will be described. The first bent portion 36a of the present embodiment forms an acute angle on the flat terminal 3 and the fitting portion entrance side in the insertion / extraction direction of the male connector 2 (that is, the Y-axis direction in FIG. 8), and the second bent portion 36b An acute angle is formed between the inner surface of the fitting portion 20 and the back side of the fitting portion. Therefore, as in the first and second embodiments, the relationships of Fmo> Fmi and Ffo> Ffi are established, so that once the male connector 2 is inserted into the fitting portion 20, it is difficult to remove. Therefore, the connector set 10b can suppress the sliding in the insertion / extraction direction of the male connector 2 similarly to the connector set 10 of 1st Example.

さらに、本実施例では、切込み３６ｚが挿通方向に対して斜めに設けられている（即ち、折り曲げ線が挿通方向に対して斜めである）ため、雄コネクタ２の幅方向（即ち、図８のＸ軸方向）において、第１折り曲げ部３６ａは平板端子３とＸ軸の負方向で鋭角を成す。そのような構造により、雄コネクタ２が、挿通方向から見て幅方向における左側（即ち、Ｘ軸の負方向）に動く際に、平板端子３と先端エッジ３６ａｅの間に生じる摩擦力Ｆｍｌ（即ち、雄コネクタ２が幅方向における左側に動く際に雄コネクタ２にかかる摩擦力）は、雄コネクタ２が幅方向における右側（即ち、Ｘ軸の正方向）に動く際に、平板端子３と先端エッジ３６ａｅの間に生じる摩擦力Ｆｍｒ（即ち、雄コネクタ２が幅方向における右側に動く際に雄コネクタ２にかかる摩擦力）よりも大きくなる（Ｆｍｌ＞Ｆｍｒ）。即ち、雄コネクタ２は、嵌合部２０の幅方向において、右側よりも左側へ動き難くなる。一方において、第２折り曲げ部３６ｂは、嵌合部２０内面とＸ軸の正方向で鋭角を成す。そのような構造により、雄コネクタ２が幅方向における左側に動く際に、嵌合部２０内面と先端エッジ３６ｂｅの間に生じる摩擦力Ｆｆｌ（即ち、雄コネクタ２が幅方向における左側に動く際に雌コネクタ４にかかる摩擦力）は、雄コネクタ２が幅方向における右側に動く際に、嵌合部２０内面と先端エッジ３６ｂｅの間に生じる摩擦力Ｆｆｒ（即ち、雄コネクタ２が幅方向における右側に動く際に雌コネクタ４にかかる摩擦力）よりも大きくなる（Ｆｆｌ＞Ｆｆｒ）。即ち、板バネ３６（の第２折り曲げ部３６ｂ）は、雌コネクタ４に対して、嵌合部２０の幅方向における右側よりも左側へ動き難くなる。雄コネクタ２の幅が、嵌合部２０内部の幅より短い場合に、雄コネクタ２を嵌合部２０内部の右側（Ｘ軸の正方向側）に当接するように挿通することにより、雄コネクタ２が嵌合部２０内部において幅方向に摺動するのを抑制できる。即ち、本実施例における雄コネクタ２は、板バネ３６によって挿抜方向に動き難くなるとともに、幅方向における左側にも動き難くなる。車両の振動やコネクタセットの熱変形に起因して、雄コネクタが挿抜方向及び幅方向に摺動することを抑制できる。 Further, in the present embodiment, the notch 36z is provided obliquely with respect to the insertion direction (that is, the folding line is oblique with respect to the insertion direction), so that the width direction of the male connector 2 (that is, FIG. 8). In the X axis direction), the first bent portion 36a forms an acute angle with the flat plate terminal 3 in the negative direction of the X axis. With such a structure, when the male connector 2 moves to the left in the width direction as viewed from the insertion direction (that is, the negative direction of the X axis), a frictional force Fml (that is, between the flat terminal 3 and the tip edge 36ae) The frictional force applied to the male connector 2 when the male connector 2 moves to the left side in the width direction is the same as the flat terminal 3 and the tip when the male connector 2 moves to the right side in the width direction (that is, the positive direction of the X axis). It becomes larger than the frictional force Fmr generated between the edges 36ae (that is, the frictional force applied to the male connector 2 when the male connector 2 moves to the right in the width direction) (Fml> Fmr). That is, the male connector 2 is less likely to move to the left side than the right side in the width direction of the fitting portion 20. On the other hand, the second bent portion 36b forms an acute angle with the inner surface of the fitting portion 20 and the positive direction of the X axis. With such a structure, when the male connector 2 moves to the left in the width direction, the frictional force Ffl generated between the inner surface of the fitting portion 20 and the tip edge 36be (that is, when the male connector 2 moves to the left in the width direction). The friction force applied to the female connector 4 is a friction force Ffr generated between the inner surface of the fitting portion 20 and the tip edge 36be when the male connector 2 moves to the right side in the width direction (that is, the male connector 2 has the right side in the width direction). (Friction force applied to the female connector 4 when moving in the direction) (Ffl> Ffr). That is, the leaf spring 36 (the second bent portion 36b thereof) is less likely to move to the left side than the right side in the width direction of the fitting portion 20 with respect to the female connector 4. When the width of the male connector 2 is shorter than the width inside the fitting portion 20, the male connector 2 is inserted so as to abut on the right side (the positive side of the X axis) inside the fitting portion 20. 2 can be prevented from sliding in the width direction inside the fitting portion 20. That is, the male connector 2 in the present embodiment is difficult to move in the insertion / extraction direction by the leaf spring 36, and is also difficult to move to the left side in the width direction. The male connector can be prevented from sliding in the insertion / removal direction and the width direction due to the vibration of the vehicle or the thermal deformation of the connector set.

本実施例のコネクタセット１０ｂの留意点を説明する。本実施例では、嵌合部２０の幅方向（即ち、図８のＸ軸方向）において、第１折り曲げ部３６ａが平板端子３とＸ軸の負方向で成す角度が鋭角になるように第１折り曲げ部３６ａが立ち上げられ、第２折り曲げ部３６ｂが嵌合部２０内面とＸ軸の正方向で成す角度が鋭角になるように第２折り曲げ部３６ｂが立ち上げられている。そのため、Ｆｍｌ＞Ｆｍｒ、Ｆｆｌ＞Ｆｆｒとなり、雄コネクタ２がＸ軸の負方向に摺動することを抑制できるが、第１折り曲げ部３６ａ及び第２折り曲げ部３６ｂの折り曲げ方はこれに限られない。例えば、第１折り曲げ部３６ａが平板端子３とＸ軸の正方向で成す角度が鋭角になるように第１折り曲げ部３６ａを立ち上げ、第２折り曲げ部３６ｂが嵌合部２０内面とＸ軸の負方向で成す角度が鋭角になるように第２折り曲げ部３６ｂを立ち上げてもよい。この場合、Ｆｍｌ＜Ｆｍｒ、Ｆｆｌ＜Ｆｆｒとなるため、雄コネクタ２を嵌合部２０内部の左側（図８のＸ軸の負方向）に当接するように挿通することにより、雄コネクタ２が嵌合部２０内部において幅方向に摺動するのを抑制できる。また、板バネ３６は、第１折り曲げ部３６ａと第２折り曲げ部３６ｂの切込みが、連続せずに別々に設けられていてもよい。このとき、第１折り曲げ部３６ａと第２折り曲げ部３６ｂの折り曲げ線は、必ずしも平行でなくてもよい。第１折り曲げ部３６ａと第２折り曲げ部３６ｂの少なくとも一方の折り曲げ線が、雄コネクタ２の挿抜方向に対して斜めであるような構成であってもよい。 The points to be noted of the connector set 10b of the present embodiment will be described. In the present embodiment, in the width direction of the fitting portion 20 (that is, the X-axis direction in FIG. 8), the first bent portion 36a is first sharp so that the angle formed by the flat terminal 3 and the negative direction of the X-axis is an acute angle. The bent portion 36a is raised, and the second bent portion 36b is raised so that the angle formed between the inner surface of the fitting portion 20 and the positive direction of the X axis is an acute angle. Therefore, Fml> Fmr, Ffl> Ffr, and the male connector 2 can be prevented from sliding in the negative direction of the X-axis, but the method of bending the first bent portion 36a and the second bent portion 36b is not limited to this. . For example, the first bent portion 36a is raised so that the angle formed between the first bent portion 36a and the flat terminal 3 in the positive direction of the X axis is an acute angle, and the second bent portion 36b is connected to the inner surface of the fitting portion 20 and the X axis. The second bent portion 36b may be raised so that the angle formed in the negative direction becomes an acute angle. In this case, since Fml <Fmr and Ffl <Ffr, the male connector 2 is fitted by inserting the male connector 2 into contact with the left side (the negative direction of the X axis in FIG. 8) inside the fitting portion 20. Sliding in the width direction inside the joint portion 20 can be suppressed. Further, the leaf spring 36 may be provided separately with the cuts of the first bent portion 36a and the second bent portion 36b being not continuous. At this time, the folding lines of the first bent portion 36a and the second bent portion 36b do not necessarily have to be parallel. A configuration in which at least one fold line of the first fold portion 36a and the second fold portion 36b is oblique to the insertion / extraction direction of the male connector 2 may be employed.

次に、図９、図１０を参照して、第４実施例のコネクタセット１０ｃについて説明する。本実施例では、第１実施例と同じ機能を有する部材には同じ符号を付し、その説明を省略する。図９は、本実施例の板バネ４６である。板バネ４６には、第２、第３実施例と同様の切込み４６ｚが、図９のＸ軸方向に沿って２つ設けられている。第１折り曲げ部４６ａは、切込み４６ｚに沿って紙面の裏側から表側へ折り曲げ線Ｌ３で折り曲げられて立ち上げられる。他方、第２折り曲げ部４６ｂは、切込み４６ｚに沿って紙面の表側から裏側へ折り曲げ線Ｌ３で折り曲げられて立ち上げられる。板バネ４６は、図９の板バネ４６のＸ軸方向における両側が、嵌合部２０内部の幅方向における両側に圧入されることにより取り付けられる。図１０は、板バネ４６が雌コネクタ４に取り付けられたコネクタセット１０ｃの、幅方向における断面図である。第１折り曲げ部４６ａは平板端子３と嵌合部入口側で鋭角を成し、その先端エッジ４６ａｅは平板端子３と接触する。他方、第２折り曲げ部４６ｂは嵌合部２０内面と嵌合部奥側で鋭角を成し、その先端エッジ４６ｂｅは嵌合部２０内面と接触する。そのような構造により、雄コネクタ２は一旦雌コネクタ４に挿通されると、抜去し難くなる。また、雌コネクタ４が制止部１４（図示略）を有することで、雄コネクタの挿通方向における摺動も抑制できる。さらに、本実施例では、図９のＸ軸方向（即ち、嵌合部２０の幅方向）において、第１折り曲げ部４６ａが２つ形成される。即ち、図１０に示すように、先端エッジ４６ａｅは、嵌合部２０の幅方向において、平板端子３と２箇所において接触する。そのような構造により、平板端子３は、Ｙ軸を回転の軸として回転し難くなる。上記のように、幅方向において第１折り曲げ部を２箇所有するような板バネを用いることにより、雄コネクタ２が挿抜方向に動き難くなるだけでなく、挿抜方向を回転の軸とする回転運動も起こりにくくなる。 Next, a connector set 10c according to a fourth embodiment will be described with reference to FIGS. In the present embodiment, members having the same functions as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. FIG. 9 shows the leaf spring 46 of this embodiment. The leaf spring 46 is provided with two cuts 46z similar to those in the second and third embodiments along the X-axis direction in FIG. The first bent portion 46a is raised from the back side of the paper surface to the front side along the notch 46z by a bend line L3. On the other hand, the second bent portion 46b is raised from the front side to the back side of the paper along the notch 46z by a bend line L3. The plate spring 46 is attached by press-fitting both sides in the X-axis direction of the plate spring 46 in FIG. 9 to both sides in the width direction inside the fitting portion 20. FIG. 10 is a cross-sectional view in the width direction of the connector set 10 c in which the leaf spring 46 is attached to the female connector 4. The first bent portion 46 a forms an acute angle with the flat plate terminal 3 on the inlet side of the fitting portion, and the tip edge 46 ae contacts the flat plate terminal 3. On the other hand, the second bent portion 46b forms an acute angle with the inner surface of the fitting portion 20 and the inner side of the fitting portion, and the tip edge 46be contacts the inner surface of the fitting portion 20. Due to such a structure, once the male connector 2 is inserted into the female connector 4, it is difficult to remove. Moreover, since the female connector 4 has the restraining part 14 (not shown), the sliding in the insertion direction of a male connector can also be suppressed. Furthermore, in the present embodiment, two first bent portions 46a are formed in the X-axis direction of FIG. 9 (that is, the width direction of the fitting portion 20). That is, as shown in FIG. 10, the leading edge 46 ae contacts the flat plate terminal 3 at two locations in the width direction of the fitting portion 20. Such a structure makes it difficult for the flat terminal 3 to rotate about the Y axis as a rotation axis. As described above, by using a leaf spring having two first bent portions in the width direction, not only does the male connector 2 become difficult to move in the insertion / removal direction, but also a rotational movement with the insertion / removal direction as the axis of rotation. Less likely to occur.

本実施例のコネクタセット１０ｃの留意点について説明する。本実施例では幅方向において２つの第１折り曲げ部４６ａを有するが、２つより多くてもよい。また、本実施例では、折り曲げ線（例えば線Ｌ３）は挿抜方向と直交するように設けられているが、折り曲げ線の方向は、これに限られない。即ち、折り曲げ線が挿抜方向に対して斜めであってもよい。また、第１折り曲げ部と第２折り曲げ部の切込みは、別々に設けられていてもよい。さらに、第１折り曲げ部と第２折り曲げ部の折り曲げ線は、必ずしも互いに平行でなくてもよい。 The points to be noted of the connector set 10c of the present embodiment will be described. In the present embodiment, the two first bent portions 46a are provided in the width direction, but the number may be more than two. In this embodiment, the folding line (for example, the line L3) is provided so as to be orthogonal to the insertion / extraction direction, but the direction of the folding line is not limited to this. That is, the fold line may be oblique to the insertion / extraction direction. Moreover, the notch | incision of a 1st bending part and a 2nd bending part may be provided separately. Further, the fold lines of the first fold portion and the second fold portion do not necessarily have to be parallel to each other.

第１実施例から第４実施例に共通する留意点について説明する。第１折り曲げ部６ａ、２６ａ、３６ａ、４６ａは嵌合部２０の奥側から入口側に折り曲げられ、第２折り曲げ部６ｂ、２６ｂ、３６ｂ、４６ｂは、嵌合部２０の入口側から奥側に折り曲げられるが、折り曲げられる方向は、これに限られない。第１折り曲げ部が平板端子３と嵌合部入口側で鋭角を成し、第２折り曲げ部が嵌合部２０内面と嵌合部奥側で鋭角を成す構成であれば、第１折り曲げ部は嵌合部２０の入口側から奥側に折り曲げられ、第２折り曲げ部は嵌合部２０の奥側から入口側に折り曲げられてもよい。また、制止部は、雌コネクタ４にではなく、雄コネクタ２に設けられていてもよい。雄コネクタ２が嵌合部２０の内部を予め定められた位置よりも挿通方向に沿ってそれ以上奥に進むことを妨げる役割を有するのであれば、制止部は、どちらのコネクタに設けられていてもよいし、コネクタのどの位置にあってもよい。また、第１折り曲げ部が板バネの平面と嵌合部奥側で成す角度と、第２折り曲げ部が板バネの平面と嵌合部入口側で成す角度は、必ずしも同じでなくてもよい。また、板バネの雌コネクタへの取り付けは、圧入以外の方法であってもよい。また、板バネの外枠の形は、雌コネクタ４に適切に取り付けられる形状であれば、どのような形でもよい。即ち、板バネの外枠が切込みの形状になっていてもよいし、直線であってもよい。さらに、図１、図６、図８、図１０によると、雄コネクタ２は、嵌合部２０の内部において、板バネに対してＺ軸の正方向側に挿通されるが、雄コネクタ２（の平板端子３）と板バネの位置関係は、これに限られない。第１折り曲げ部が、その先端エッジが平板端子３と接触するとともに、平板端子３と嵌合部入口側で成す角度が鋭角であり、第２折り曲げ部が、その先端エッジが嵌合部２０の内面と接触するとともに、嵌合部２０の内面と嵌合部奥側で成す角度が鋭角であれば、雄コネクタと板バネの嵌合部内部における位置関係はどのようであってもよい。例えば、雄コネクタ２が、嵌合部２０の内部において、板バネに対してＺ軸の負方向側に挿通される構成であってもよい。 Points to be noted in common with the first to fourth embodiments will be described. The first bent portions 6a, 26a, 36a, 46a are bent from the rear side of the fitting portion 20 to the inlet side, and the second bent portions 6b, 26b, 36b, 46b are bent from the inlet side of the fitting portion 20 to the inner side. Although it is bent, the direction of bending is not limited to this. If the first bent portion has an acute angle at the flat terminal 3 and the fitting portion entrance side, and the second bent portion has an acute angle at the inner surface of the fitting portion 20 and the inner side of the fitting portion, the first bent portion is The fitting part 20 may be bent from the inlet side to the back side, and the second bent part may be bent from the back side of the fitting part 20 to the inlet side. Further, the restraining portion may be provided not on the female connector 4 but on the male connector 2. As long as the male connector 2 has a role of preventing the interior of the fitting portion 20 from proceeding further in the insertion direction than the predetermined position, the stop portion is provided in which connector. Or it may be in any position of the connector. In addition, the angle formed by the first bent portion on the flat surface of the leaf spring and the rear side of the fitting portion and the angle formed by the second bent portion on the flat surface of the leaf spring and the fitting portion inlet side are not necessarily the same. Further, the plate spring may be attached to the female connector by a method other than press fitting. The shape of the outer frame of the leaf spring may be any shape as long as it can be appropriately attached to the female connector 4. That is, the outer frame of the leaf spring may have a cut shape or a straight line. Further, according to FIGS. 1, 6, 8, and 10, the male connector 2 is inserted into the positive direction side of the Z-axis with respect to the leaf spring inside the fitting portion 20. The positional relationship between the flat terminal 3) and the leaf spring is not limited to this. The first bent portion has its leading edge in contact with the flat terminal 3 and an angle formed between the flat terminal 3 and the fitting portion entrance side is an acute angle, and the second bent portion has its leading edge of the fitting portion 20. As long as the angle formed between the inner surface of the fitting portion 20 and the inner side of the fitting portion is an acute angle, the positional relationship between the male connector and the leaf spring inside the fitting portion may be any. For example, the male connector 2 may be inserted into the negative direction side of the Z axis with respect to the leaf spring inside the fitting portion 20.
