Description

本発明は雌端子および雌端子を使用する電気コネクタに関し、特に、金属板を折り曲げて形成された角筒状の嵌合部を有する雌端子および雌端子を使用する電気コネクタに関する。   The present invention relates to a female terminal and an electrical connector using the female terminal, and more particularly to a female terminal having a rectangular tube-shaped fitting portion formed by bending a metal plate and an electrical connector using the female terminal.

電気コネクタに使用される雌端子の形状として角筒状の嵌合部と、この嵌合部内に配置された接触片すなわち接点ばね部材を有するものが知られている（例えば、特許文献１参照）。この雌端子は、接触部（嵌合部）の上壁内面に端子の挿抜方向に沿って配置された２つの凸部を有するとともに、嵌合部の底壁から２つの凸部に向けて内側に切り起こした接触片を有する。相手方の雄端子が、この雌端子に挿入されると雄端子の接触部は、前述の２つの凸部と接触片との間に、接触片を押し広げるように挿入されて電気的に接続されるようになっている。
特開２０００−２０８１９６号公報（図３） As a shape of a female terminal used for an electric connector, a rectangular tube-shaped fitting portion and a contact piece arranged in the fitting portion, that is, a contact spring member is known (for example, see Patent Document 1). . The female terminal has two convex portions arranged along the insertion / removal direction of the terminal on the inner surface of the upper wall of the contact portion (fitting portion), and the inner side from the bottom wall of the fitting portion toward the two convex portions. It has a contact piece cut and raised. When the mating male terminal is inserted into the female terminal, the contact portion of the male terminal is inserted between the two convex portions and the contact piece to expand the contact piece and is electrically connected. It has become so.
JP 2000-208196 A (FIG. 3)

上記の従来技術において、雌端子の嵌合部内の凸部と接触片は、雄端子の挿入によって互いに離れる方向に付勢される。換言すると、雄端子の挿入によって嵌合部には上壁と底壁に対し互いに離隔させる方向へ力が働く。このため、一般的に金属板を折り曲げて、金属板の端部同士を単に折り重ねて形成されている嵌合部は、雄端子の挿入により上下方向へ離隔させる力が発生して嵌合部が開くように変形するおそれがある。嵌合部が変形すると、雄端子と雌端子との接圧が適切に維持されず電気的な接続の信頼性が低下する。特に、雌端子が慣性ロック用の電気コネクタに使用される場合は、コネクタ同士の嵌合時に瞬間的に大きな接圧が発生するので、このような問題が生じやすい。また、コネクタ内の雌端子に接続されている電線を引っ張った場合、雌端子の嵌合部が応力を受けて変形することがある。   In the above prior art, the convex portion and the contact piece in the fitting portion of the female terminal are urged away from each other by the insertion of the male terminal. In other words, the insertion of the male terminal exerts a force on the fitting portion in a direction in which the upper wall and the bottom wall are separated from each other. For this reason, the fitting part generally formed by bending the metal plate and simply folding the end parts of the metal plate generates a force that separates the metal plate in the vertical direction by inserting the male terminal. There is a risk of deformation to open. When the fitting portion is deformed, the contact pressure between the male terminal and the female terminal is not properly maintained, and the reliability of electrical connection is lowered. In particular, when a female terminal is used in an electrical connector for inertia lock, such a problem is likely to occur because a large contact pressure is instantaneously generated when the connectors are fitted together. Moreover, when the electric wire connected to the female terminal in the connector is pulled, the fitting portion of the female terminal may be deformed by receiving stress.

本発明は、上記事情に鑑みてなされたものであり、嵌合時に、角筒状の嵌合部を形成する金属板の合わせ目が外方に開くおそれのない電気的接続の信頼性の高い雌端子および雌端子を使用する電気コネクタを提供することを目的とする。   The present invention has been made in view of the above circumstances, and at the time of fitting, there is a high reliability of electrical connection in which there is no possibility that the joint of the metal plate forming the rectangular tube-shaped fitting portion will open outward. An object is to provide a female terminal and an electrical connector using the female terminal.

本発明の雌端子は、金属板を折り曲げて形成された角筒状の嵌合部と、嵌合部内に配置された接点ばね部材と、嵌合部に連続する電線接続部とを備え、嵌合部に挿入された相手方の雄端子に接点ばね部材が接触して、雄端子と電気的接続をなす雌端子において、嵌合部を形成する金属板の端部同士が、嵌合部の、接点ばね部材の変位方向に沿う面で、互いに離隔しないように結合されていることを特徴とするものである。   A female terminal of the present invention includes a rectangular tube-shaped fitting portion formed by bending a metal plate, a contact spring member disposed in the fitting portion, and an electric wire connecting portion continuous to the fitting portion. The contact spring member comes into contact with the mating male terminal inserted into the mating portion, and in the female terminal that makes electrical connection with the male terminal, the end portions of the metal plate forming the fitting portion are of the fitting portion, The contact spring members are joined so as not to be separated from each other on the surface along the displacement direction of the contact spring members.

金属板の端部同士は、互いに分離しにくいように嵌まり合う相補的係合部を有していることが好ましい。この相補的係合部は、ありとあり溝状切欠とすることができる。   It is preferable that the end portions of the metal plate have complementary engaging portions that fit together so as to be difficult to separate from each other. The complementary engagement portion can be a groove-shaped notch.

また、この雌端子を使用する本発明の電気コネクタは、端子受容孔を有する絶縁ハウジングを備え、端子受容孔内に請求項１または２記載の雌端子を配置してなることを特徴とするものである。   In addition, an electrical connector of the present invention using this female terminal includes an insulating housing having a terminal receiving hole, and the female terminal according to claim 1 or 2 is disposed in the terminal receiving hole. It is.

本発明の雌端子は、角筒状の嵌合部を形成する金属板の端部同士が、嵌合部の、接点ばね部材の変位方向に沿う面で、互いに離隔しないように結合されているので、次の効果を奏する。すなわち、嵌合時に雄端子が挿入される雌端子の角筒状の嵌合部を形成する金属板が互いに離隔しないように結合されているので、合わせ目が外方に開くおそれのない電気的接続の信頼性の高い雌端子およびこれを使用する電気コネクタが得られる。   In the female terminal of the present invention, the end portions of the metal plates forming the rectangular tube-shaped fitting portion are joined so as not to be separated from each other on the surface of the fitting portion along the displacement direction of the contact spring member. Therefore, the following effects are produced. That is, since the metal plates that form the rectangular tube-shaped fitting portion of the female terminal into which the male terminal is inserted during fitting are joined so as not to be separated from each other, there is no possibility that the joint will open outward. A female terminal with high connection reliability and an electrical connector using the same are obtained.

金属板の端部同士が、互いに分離しにくいように嵌まり合う相補的係合部を有している場合は、金属板の互いに組み合う端部の形状のみで効果的に端部同士を結合することができる。   When the ends of the metal plates have complementary engaging portions that fit so as to be difficult to separate from each other, the ends are effectively joined only by the shape of the end portions of the metal plates that are combined with each other. be able to.

Here, the front part and the rear part of the female terminal 1 are referred to as the front part and the opposite side as the rear part where the counterpart male terminal 40 (FIGS. 6 and 7) is inserted.

嵌合部２は、底壁２ａ、底壁２ａの両側で底壁２ａに直角に立設された側壁２ｂ、２ｃ、２ｄ、上壁２ｅ、２ｆを有する。なお、ここで底壁２ａ、側壁２ｂ〜２ｄ、上壁２ｅ、２ｆとは、正面図や右側面図に基づいて説明の便宜上称するものである。上壁２ｅと上壁２ｆは雌端子１の挿抜方向Ｄ（図１（ｂ））に沿って互いに離隔している。上壁２ｅ、２ｆの間には矩形の開口６が形成されている。側壁２ｂの前部には上壁２ｅと、この上壁２ｅに連続して形成された側壁２ｄが、側壁２ｃに向けて折り曲げられるように一体に形成されている。側壁２ｃと側壁２ｄは、互いに組み合うように形成されている。すなわち、側壁２ｃの、側壁２ｄ側の端部には、あり溝状切欠（相補的係合部）８（図２）が形成され、側壁２ｄの端部には、このあり溝状切欠８と相補的な形状のあり（相補的係合部）１０が形成され、互いに嵌め合わされている。この嵌め合い構造により、側壁２ｃと側壁２ｄは、上下方向すなわち底壁２ａ側と上壁２ｅ側に引き離されにくい構造になっている。なお、側壁２ｃと側壁２ｄを一面側の側壁と称する。相補的係合部としては、あり１０やあり溝状切欠８に限定されるものではなく、湾曲状の相補的形状であってもよい。   The fitting portion 2 includes a bottom wall 2a, side walls 2b, 2c, and 2d, and upper walls 2e and 2f that are erected at right angles to the bottom wall 2a on both sides of the bottom wall 2a. Here, the bottom wall 2a, the side walls 2b to 2d, and the upper walls 2e and 2f are referred to for convenience of explanation based on a front view and a right side view. The upper wall 2e and the upper wall 2f are separated from each other along the insertion / removal direction D of the female terminal 1 (FIG. 1B). A rectangular opening 6 is formed between the upper walls 2e and 2f. An upper wall 2e and a side wall 2d continuously formed on the upper wall 2e are integrally formed at the front portion of the side wall 2b so as to be bent toward the side wall 2c. The side wall 2c and the side wall 2d are formed so as to be combined with each other. That is, a dovetail notch (complementary engaging portion) 8 (FIG. 2) is formed at the end of the side wall 2c on the side of the side wall 2d, and the dovetail notch 8 is formed at the end of the side wall 2d. Complementary shapes (complementary engagement portions) 10 are formed and fitted to each other. By this fitting structure, the side wall 2c and the side wall 2d are structured to be difficult to separate in the vertical direction, that is, the bottom wall 2a side and the top wall 2e side. The side wall 2c and the side wall 2d are referred to as one side wall. The complementary engaging portion is not limited to the dovetail 10 or the dovetail-shaped notch 8, but may be a curved complementary shape.

他方、側壁２ｃの後部には、側壁２ｂの上縁１２上に折り曲げられた狭幅の内側上壁２ｇ（図１（ｂ）、図２（ｃ））が形成されている。また、前述の広幅の上壁２ｆは、側壁２ｂの後部に内側上壁２ｇ上に折り曲げられるように形成されている。上壁２ｆには、側壁２ｂの上縁１２近傍に矩形の切欠１４（図１（ａ））が形成され、内側上壁２ｇの先端が、上壁２ｆの折曲げ部分に干渉しないようにしている。   On the other hand, at the rear part of the side wall 2c, a narrow inner upper wall 2g (FIGS. 1B and 2C) is formed which is bent on the upper edge 12 of the side wall 2b. The above-described wide upper wall 2f is formed to be bent on the inner upper wall 2g at the rear portion of the side wall 2b. A rectangular notch 14 (FIG. 1A) is formed in the upper wall 2f in the vicinity of the upper edge 12 of the side wall 2b so that the tip of the inner upper wall 2g does not interfere with the bent portion of the upper wall 2f. Yes.

次に、図３を併せて参照して、嵌合部２内の、相手方の雄端子４０との接触構造について説明する。図３は、図１（ａ）のIII―III線に沿う断面図である。底壁２ａの前部には、嵌合部２内に打ち出しにより矩形の凸部１６（図１（ｃ）、図３）が形成されている。また、前述の内側上壁２ｇには、嵌合部２内を前方に延びる舌片状の接触片（接点ばね部材）１８が一体に形成されている。接触片１８は凸部１６に対向するように凸部１６近傍に延び、さらに接触片１８の先端部１８ａは、上壁２ｅに向けて湾曲しながら凸部１６から離隔するように延びている。この先端部１８ａは、挿入される雄端子４０の案内面として機能する。接触片１８は、凸部１６に最も接近した箇所が接点１８ｂとなる。すなわち、雄端子４０は、この接点１８ｂと凸部１６との間の間隙Ｇ（図３）に挿入されて雌端子１と電気的に接続される。   Next, a contact structure with the mating male terminal 40 in the fitting portion 2 will be described with reference to FIG. FIG. 3 is a sectional view taken along line III-III in FIG. At the front part of the bottom wall 2a, a rectangular convex part 16 (FIGS. 1C and 3) is formed by punching into the fitting part 2. In addition, a tongue-like contact piece (contact spring member) 18 extending forward in the fitting portion 2 is formed integrally with the inner upper wall 2g. The contact piece 18 extends in the vicinity of the projection 16 so as to face the projection 16, and the tip 18a of the contact piece 18 extends away from the projection 16 while being curved toward the upper wall 2e. The tip 18a functions as a guide surface for the male terminal 40 to be inserted. In the contact piece 18, the point closest to the convex portion 16 is a contact 18 b. That is, the male terminal 40 is inserted into the gap G (FIG. 3) between the contact 18 b and the convex portion 16 and is electrically connected to the female terminal 1.

次に、図４および図５を参照して、雌端子１を使用する電気コネクタ（プラグコネクタ）（以下、単にコネクタという）１００について説明する。図４および図５は、コネクタ１００を示し、図４（ａ）は平面図、図４（ｂ）は正面図、図５（ａ）は背面図、図５（ｂ）は側面図、図５（ｃ）は図５（ａ）のＶｃ−Ｖｃ線に沿う断面図をそれぞれ示す。なお、図４および図５において、雌端子１は省略してある。コネクタ１００は、略直方形状であり、絶縁性の合成樹脂から形成されたハウジング（絶縁ハウジング）１０１を有する。ハウジング１０１には、ハウジング１０１の嵌合面１０２から後面１０４にかけて貫通している４つの端子受容孔１０６が１列形成されている。各端子受容孔１０６の先端には雄端子４０が挿入される案内孔１３２が形成されている。ハウジング１０１の上面１０８の両端部には、嵌合面１０２から後面１０４に延びるリブ１１０が上方に突設されている。   Next, an electrical connector (plug connector) 100 (hereinafter simply referred to as a connector) 100 that uses the female terminals 1 will be described with reference to FIGS. 4 and 5. 4 and 5 show the connector 100, FIG. 4 (a) is a plan view, FIG. 4 (b) is a front view, FIG. 5 (a) is a rear view, FIG. 5 (b) is a side view, and FIG. (C) shows each sectional drawing which follows the Vc-Vc line | wire of Fig.5 (a). 4 and 5, the female terminal 1 is omitted. The connector 100 has a substantially rectangular shape and includes a housing (insulating housing) 101 formed of an insulating synthetic resin. The housing 101 is formed with a row of four terminal receiving holes 106 penetrating from the fitting surface 102 to the rear surface 104 of the housing 101. A guide hole 132 into which the male terminal 40 is inserted is formed at the tip of each terminal receiving hole 106. At both ends of the upper surface 108 of the housing 101, ribs 110 extending from the fitting surface 102 to the rear surface 104 protrude upward.

上面１０８の後端部両端には、リブ１１０に連続してハウジング１０１の上方および側方に凸部１１２が形成されている。また、上面１０８には、嵌合面１０２側に固定端１１４ａを有するラッチアーム１１４が、互いに離隔したリブ１１０、１１０の中間に形成されている。ラッチアーム１１４の自由端部１１４ｂは、上面１０８から離隔しており、上面１０８に対して弾性的に撓むことができるようになっている。ラッチアーム１１４の自由端部１１４ｂには上方に隆起した指掛突起１１６が形成されており、また、固定端１１４ａと自由端部１１４ｂとの間には、１対の係合突起１１８、１１８が上方に向けて形成されている。この係合突起１１８は、コネクタ１００の挿抜方向１２０（図４（ａ））の同じ位置に互いに挿抜方向１２０と直交方向に離隔して形成されている。各係合突起１１８の先端１１８ａは、急傾斜の平面に形成されている。   Convex portions 112 are formed at both ends of the rear end portion of the upper surface 108 so as to be continuous with the ribs 110 and above and to the side of the housing 101. On the upper surface 108, a latch arm 114 having a fixed end 114a on the fitting surface 102 side is formed in the middle of the ribs 110, 110 spaced apart from each other. The free end portion 114 b of the latch arm 114 is separated from the upper surface 108 and can be elastically bent with respect to the upper surface 108. A finger hooking protrusion 116 protruding upward is formed on the free end 114b of the latch arm 114, and a pair of engaging protrusions 118, 118 are formed between the fixed end 114a and the free end 114b. It is formed upward. The engagement protrusions 118 are formed at the same position in the insertion / removal direction 120 (FIG. 4A) of the connector 100 and spaced apart from each other in the direction orthogonal to the insertion / removal direction 120. The front end 118a of each engagement protrusion 118 is formed in a steeply inclined plane.

ラッチアーム１１４は、前述のリブ１１０や凸部１１２により保護されている。すなわち、電線等の外部の部品がラッチアーム１１４と上面１０８との間に進入して、偶発的にラッチアーム１１４を変形あるいは折損することから防止している。図５（ｃ）に示すように各端子受容孔１０６に対応して、コネクタ１００の底壁１２２に形成された開口１２４内に係止アーム１２６が形成されている。係止アーム１２６は開口１２４の後端側から前方に延び、先端に端子受容孔１０６内に突出する突起１２６ａを有する。この突起１２６ａにより雌端子１が端子受容孔１０６内に係止される。また、コネクタ１００の後部には、外方に突出する他の凸部１２８が、底壁１２２からコネクタ１００の側壁１３０にかけて形成されている。   The latch arm 114 is protected by the rib 110 and the convex portion 112 described above. That is, an external component such as an electric wire enters between the latch arm 114 and the upper surface 108 to prevent the latch arm 114 from being accidentally deformed or broken. As shown in FIG. 5C, corresponding to each terminal receiving hole 106, a locking arm 126 is formed in an opening 124 formed in the bottom wall 122 of the connector 100. The locking arm 126 has a protrusion 126 a that extends forward from the rear end side of the opening 124 and protrudes into the terminal receiving hole 106 at the tip. The female terminal 1 is locked in the terminal receiving hole 106 by the protrusion 126a. Further, at the rear portion of the connector 100, another convex portion 128 protruding outward is formed from the bottom wall 122 to the side wall 130 of the connector 100.

次に、図６および図７を参照して、雌端子１を収容したコネクタ１００が相手方の電気コネクタ（ヘッダコネクタ）（以下、単にコネクタという）２００と嵌合する状態について説明する。図６はコネクタ１００とコネクタ２００が嵌合途中にある状態を示す断面図であり、図７はコネクタ１００とコネクタ２００が完全に嵌合した状態を示す断面図である。図６および図７に示すように、雌端子１が端子受容孔１０６内に収容されると、雌端子１の開口６内に係止アーム１２６の突起１２６ａが係合して、雌端子１は端子受容孔１０６内に係止される。このとき雌端子１の接触片１８と凸部１６との間の間隙Ｇは、コネクタ１００の案内孔１３２に位置合せされる。   Next, with reference to FIG. 6 and FIG. 7, a state in which the connector 100 housing the female terminal 1 is engaged with a mating electrical connector (header connector) (hereinafter simply referred to as a connector) 200 will be described. 6 is a cross-sectional view showing a state where the connector 100 and the connector 200 are in the middle of fitting, and FIG. 7 is a cross-sectional view showing a state where the connector 100 and the connector 200 are completely fitted. As shown in FIGS. 6 and 7, when the female terminal 1 is received in the terminal receiving hole 106, the protrusion 126 a of the locking arm 126 is engaged in the opening 6 of the female terminal 1, so that the female terminal 1 is Locked in the terminal receiving hole 106. At this time, the gap G between the contact piece 18 of the female terminal 1 and the convex portion 16 is aligned with the guide hole 132 of the connector 100.

相手方のコネクタ２００は、この実施形態では基板（ＰＣＢ）２５０上に配置されている。コネクタ２００は、絶縁性のハウジング２０２を有し、基板２５０上に位置する底壁２０４と、底壁２０４から上方に開放する嵌合凹部２０６を有する。底壁２０４には、雌端子１に対応する雄端子４０が植設されており、これらの雄端子４０が基板２５０の貫通孔２５０ａに挿入および固定されている。また側壁２０８には、嵌合凹部２０６に連通する係合口２１０が形成されている。係合口２１０は、嵌合凹部２０６内に挿入されたコネクタ１００の係合突起１１８に対応する位置に形成されている。   The mating connector 200 is disposed on a substrate (PCB) 250 in this embodiment. The connector 200 has an insulating housing 202 and has a bottom wall 204 located on the substrate 250 and a fitting recess 206 that opens upward from the bottom wall 204. Male terminals 40 corresponding to the female terminals 1 are planted on the bottom wall 204, and these male terminals 40 are inserted and fixed in the through holes 250 a of the substrate 250. Further, the side wall 208 is formed with an engagement port 210 communicating with the fitting recess 206. The engagement port 210 is formed at a position corresponding to the engagement protrusion 118 of the connector 100 inserted into the fitting recess 206.

図６に示すように、コネクタ１００をコネクタ２００の嵌合凹部２０６内に挿入すると、係合突起１１８の先端１１８ａが、コネクタ２００の上面２１２に当接する。先端１１８ａは、急角度に傾斜しているため、コネクタ１００を小さい挿入力でコネクタ２００に押し込むことはできない。従って、コネクタ１００を図６に示す位置から相当大きな力で押し込むと、係合突起１１８の先端１１８ａの斜面により、ラッチアーム１１４が矢印１３４（図６）で示すようにハウジング１０１の上面１０８側に変位される。そして、係合突起１１８の外面１１８ｂがコネクタ２００の上面２１２の内側のエッジより内方に撓むと、コネクタ１００は一気に嵌合凹部２０６内に押し込まれ、図７に示す位置に達する。コネクタ１００が図６に示す位置にあるとき、雄端子４０の先端部４０ａはコネクタ１００の案内孔１３２内に位置している。   As shown in FIG. 6, when the connector 100 is inserted into the fitting recess 206 of the connector 200, the tip 118 a of the engagement protrusion 118 abuts on the upper surface 212 of the connector 200. Since the tip 118a is inclined at a steep angle, the connector 100 cannot be pushed into the connector 200 with a small insertion force. Therefore, when the connector 100 is pushed in from the position shown in FIG. 6 with a considerably large force, the latch arm 114 is moved toward the upper surface 108 of the housing 101 as shown by the arrow 134 (FIG. 6) due to the inclined surface of the tip 118a of the engaging projection 118. Displaced. When the outer surface 118b of the engagement protrusion 118 bends inward from the inner edge of the upper surface 212 of the connector 200, the connector 100 is pushed into the fitting recess 206 all at once and reaches the position shown in FIG. When the connector 100 is in the position shown in FIG. 6, the distal end portion 40 a of the male terminal 40 is located in the guide hole 132 of the connector 100.

このように、係合突起１１８がコネクタ２００の上面２１２に当接した位置からコネクタ１００を嵌合凹部２０６に押し込むときに最大の挿入力が必要とされる。そして、係合突起１１８と上面２１２との当接関係が解除されると、コネクタ１００は嵌合途中で停止することなく、確実に完全嵌合位置まで押し込まれる。この種のコネクタ１００は、いわゆる慣性ロックタイプのコネクタと称され、半嵌合状態が回避されるようになっている。従って、慣性ロックコネクタは、構造上、嵌合の際にコネクタ１００はコネクタ２００に高速で挿入されるため、接触片１８と凸部１６に対し、瞬間的に大きな接圧が生じる。この接圧は、接触片１８を一面（接触片の変位方向に沿う面）すなわち側壁２ｄ、２ｃに沿って移動させ、側壁２ｄと側壁２ｃを互いに引き離すように作用する。しかし、側壁２ｄ、２ｃは前述の如くあり１０とあり溝状切欠８の関係に結合されているので、変形は確実に阻止され、電気的接続の信頼性が損なわれることはない。また、コネクタ１００内の雌端子１に接続されている電線３０を引っ張っても、雌端子１の嵌合部２が変形することが阻止される。   Thus, the maximum insertion force is required when the connector 100 is pushed into the fitting recess 206 from the position where the engagement protrusion 118 is in contact with the upper surface 212 of the connector 200. When the contact relationship between the engagement protrusion 118 and the upper surface 212 is released, the connector 100 is reliably pushed to the complete engagement position without stopping during the engagement. This type of connector 100 is referred to as a so-called inertia lock type connector, and a half-fitted state is avoided. Therefore, since the inertia lock connector is structurally connected, the connector 100 is inserted into the connector 200 at a high speed when mated, so that a large contact pressure is instantaneously generated between the contact piece 18 and the convex portion 16. This contact pressure acts to move the contact piece 18 along one surface (the surface along the displacement direction of the contact piece), that is, along the side walls 2d and 2c, and separate the side wall 2d and the side wall 2c from each other. However, since the side walls 2d and 2c are provided with the dovetail 10 as described above and are connected in the relationship of the groove-shaped notch 8, the deformation is surely prevented and the reliability of the electrical connection is not impaired. Moreover, even if the electric wire 30 connected to the female terminal 1 in the connector 100 is pulled, the fitting portion 2 of the female terminal 1 is prevented from being deformed.

完全嵌合位置では雄端子４０が、凸部１６と接触片１８との間の間隙Ｇに進入して、雌端子１に電気的に接続される。また、係合突起１１８が係合口２１０と合致した位置で、ラッチアーム１１４が弾発的に復帰して、係合突起１１８が係合口２１０に係合し、コネクタ同士の抜止めがなされる。   In the fully fitted position, the male terminal 40 enters the gap G between the convex portion 16 and the contact piece 18 and is electrically connected to the female terminal 1. Further, at a position where the engagement protrusion 118 is aligned with the engagement port 210, the latch arm 114 is elastically returned, the engagement protrusion 118 is engaged with the engagement port 210, and the connectors are prevented from being pulled out.
