ところで、上記の弾性接触片は、その幅寸法、板厚、弾性変位量、及び形状等をそれぞれ適宜調整することにより、タブとの接触状態を良好に保つのに必要なバネ反力を確保するものである。したがって、端子金具が小型になると、弾性接触片の幅寸法も小さくなるため、上記バネ反力を得るのが難しくなり、タブとの接続信頼性に欠けるという事情がある。   By the way, the above-mentioned elastic contact piece ensures the spring reaction force necessary for maintaining a good contact state with the tab by appropriately adjusting the width dimension, the plate thickness, the elastic displacement amount, the shape and the like. Is. Therefore, when the terminal fitting is reduced in size, the width dimension of the elastic contact piece is also reduced, so that it is difficult to obtain the spring reaction force, and the connection reliability with the tab is lacking.

＜請求項１の発明＞
弾性接触片がその幅方向両端部から中央部に向けて本体部内におけるタブの挿入経路側に近づくように湾曲する湾曲部を有しているから、仮に弾性接触片の幅寸法（湾曲部の弦方向に沿った寸法）が小さくとも、高いバネ反力を発生させることができる。したがって、端子金具が小型になっても、タブとの間に必要な接触荷重を得ることができる。 <Invention of Claim 1>
Since the elastic contact piece has a curved part that curves so as to approach the insertion path side of the tab in the main body part from both ends in the width direction toward the center part, the width dimension of the elastic contact piece (string of the curved part) Even if the dimension along the direction is small, a high spring reaction force can be generated. Therefore, even if the terminal fitting is reduced in size, a necessary contact load can be obtained between the tabs.

＜請求項２の発明＞
湾曲部は弾性接触片のうちのタブに接触する部分に形成され、湾曲部とタブとの接触面積は小さいため、弾性接触片とタブとの間の接触抵抗が低くなる。その結果、本体部内にタブを低挿入力で挿入することができる。 <Invention of Claim 2>
The curved portion is formed in a portion of the elastic contact piece that contacts the tab, and since the contact area between the curved portion and the tab is small, the contact resistance between the elastic contact piece and the tab is low. As a result, the tab can be inserted into the main body portion with a low insertion force.

＜実施形態１＞
本発明の実施形態１を図１ないし図６によって説明する。本実施形態の端子金具１０は導電性の金属板を曲げ加工等して一体に成形され、筒状の本体部１１と、本体部１１の後方に連なるオープンバレル状のバレル部１２、１３とを備えている。バレル部１２、１３は、図示しない電線の端末部に露出する芯線にかしめ付けして接続されるワイヤバレル１２と、その後方に位置して電線の端末部における被覆又はこの被覆に嵌着されるゴム栓にかしめ付けして接続されるインシュレーションバレル１３とを有している。 <Embodiment 1>
A first embodiment of the present invention will be described with reference to FIGS. The terminal fitting 10 of this embodiment is integrally formed by bending a conductive metal plate or the like, and includes a cylindrical main body portion 11 and open barrel-shaped barrel portions 12 and 13 connected to the rear of the main body portion 11. I have. Barrel portions 12 and 13 are wire barrel 12 that is connected by caulking to a core wire exposed at a terminal portion of an electric wire (not shown), and a sheath at the rear portion of the electric wire that is positioned behind or fitted to the coating. And an insulation barrel 13 connected by caulking to a rubber stopper.

本体部１１は、図４に示すように、バレル部１２、１３側から連続して延びる略水平な底板部１４と、底板部１４の幅方向両端から立ち上がる略垂直な一対の側板部１５と、両側板部１５の立ち上がり端間に架け渡されて底板部１４と対向する天板部１６とからなる。本体部１１の前面は相手端子金具６０のタブ６１の挿入口１７として開口されている。なお、タブ６１の断面形状は横長の長方形とされている。   As shown in FIG. 4, the main body portion 11 includes a substantially horizontal bottom plate portion 14 continuously extending from the barrel portions 12 and 13 side, and a pair of substantially vertical side plate portions 15 rising from both ends in the width direction of the bottom plate portion 14. It consists of a top plate portion 16 that is spanned between rising ends of both side plate portions 15 and faces the bottom plate portion 14. The front surface of the main body 11 is opened as the insertion opening 17 of the tab 61 of the mating terminal fitting 60. The cross-sectional shape of the tab 61 is a horizontally long rectangle.

天板部１６には、幅方向に２条の受け部１８が形成されている。両受け部１８は、図１に示すように、前後方向に細長く延びる形状であって、外側から内側への叩き出しにより形成されている。詳しくは両受け部１８は、断面下半円弧状をなし、前端から後方へ向けて下向きに緩く傾斜する第１傾斜部１９と、第１傾斜部１９の後端から後方へ略水平に延びる受け本体部２１と、受け本体部２１の後端から後方へ向けて上向きに急勾配で傾斜する第２傾斜部２２とからなる。   Two receiving portions 18 are formed in the top plate portion 16 in the width direction. As shown in FIG. 1, the both receiving portions 18 are elongated in the front-rear direction, and are formed by knocking from the outside to the inside. Specifically, the receiving portions 18 have a lower semicircular arc shape in cross section, a first inclined portion 19 that is gently inclined downward from the front end to the rear, and a receiver extending substantially horizontally from the rear end of the first inclined portion 19 to the rear. The main body portion 21 and the second inclined portion 22 that inclines upward and steeply from the rear end of the receiving main body portion 21 to the rear.

底板部１４の前端部の幅方向両端部には、図３に示すように、両側板部１５との間に一対のスリット２３が入れられている。また、底板部１４の前端部には帯板状の弾性接触片２４が一体に連結されている。弾性接触片２４は、両スリット２３間にて後方へ回曲状に折り返される屈曲部２５と、屈曲部２５の折り返し端から後方へ略山型に延出する延出部２６とからなる。延出部２６における山の頂部は両受け本体部２１と対向するエンボス状の接点部２７とされている。この接点部２７は、弾性接触片２４の幅方向中央部に配置されている。延出部２６の前端部、屈曲部２５及び接点部２７はそれぞれ略同幅で連なる形状とされ、延出部２６の後端部（自由端部３９）はこれらよりも幅狭に形成されている。接点部２７の後方には延出部２６の自由端部３９に向けて次第に幅狭となる移行部２８が形成されている。   As shown in FIG. 3, a pair of slits 23 are provided between the both side plate portions 15 at both ends in the width direction of the front end portion of the bottom plate portion 14. A band plate-like elastic contact piece 24 is integrally connected to the front end portion of the bottom plate portion 14. The elastic contact piece 24 includes a bent portion 25 that is folded back backward between the slits 23 and an extended portion 26 that extends rearward from the folded end of the bent portion 25 in a substantially chevron shape. The peak portion of the extended portion 26 is an embossed contact portion 27 that faces the receiving body portion 21. The contact portion 27 is disposed at the center in the width direction of the elastic contact piece 24. The front end portion, the bent portion 25, and the contact portion 27 of the extension portion 26 are formed in a shape that is continuous with substantially the same width, and the rear end portion (free end portion 39) of the extension portion 26 is formed to be narrower than these. Yes. On the rear side of the contact portion 27, a transition portion 28 that is gradually narrowed toward the free end portion 39 of the extending portion 26 is formed.

接点部２７と両受け部１８との間はタブ６１の挿入経路２９とされ、弾性接触片２４が自然状態にあるときに、接点部２７と両受け本体部２１の頂点間の上下方向の直線距離はタブ６１の板厚よりも小さくされている。本体部１１内には前方から相手端子金具６０のタブ６１が挿入され、正規挿入されたタブ６１は弾性接触片２４を撓み変形させつつ接点部２７と両受け本体部２１との間に弾性的に挟持されるようになっている。こうして接点部２７とタブ６１とが接続状態にあるときに、延出部２６の自由端部３９は底板部１４の内面に弾性的に当接し、これによって弾性接触片２４は実質的に両持ち梁状態となる。また、底板部１４における接点部２７と対向する位置には、弾性接触片２４が過度に撓み変形したときに接点部２７に下方から当接する過度撓み規制片３１が略垂直に切り起こして形成されている。この過度撓み規制片３１は、図４に示すように、底板部１４の幅方向中央から一側へ偏心して配置され、接点部２７との間が幅方向に位置ずれしている。   An insertion path 29 of the tab 61 is formed between the contact portion 27 and the both receiving portions 18, and when the elastic contact piece 24 is in a natural state, a straight line between the contact portion 27 and the apexes of the both receiving body portions 21. The distance is made smaller than the thickness of the tab 61. A tab 61 of the mating terminal fitting 60 is inserted into the main body portion 11 from the front, and the normally inserted tab 61 is elastic between the contact portion 27 and the receiving main body portion 21 while bending and deforming the elastic contact piece 24. It is supposed to be sandwiched between. Thus, when the contact portion 27 and the tab 61 are in the connected state, the free end portion 39 of the extension portion 26 elastically abuts against the inner surface of the bottom plate portion 14, whereby the elastic contact piece 24 is substantially supported at both ends. It becomes a beam state. Further, at the position facing the contact portion 27 in the bottom plate portion 14, an excessive deflection regulating piece 31 that comes into contact with the contact portion 27 from below when the elastic contact piece 24 is excessively bent and deformed is cut and raised substantially vertically. ing. As shown in FIG. 4, the excessive deflection regulating piece 31 is arranged eccentrically from the center in the width direction of the bottom plate portion 14 to one side, and is displaced in the width direction from the contact portion 27.

さて、弾性接触片２４の延出部２６には、幅方向両端から中央（接点部２７）にかけてその全幅がタブ６１の挿入経路２９に近づくように湾曲する湾曲部３２が形成されている。この湾曲部３２の曲率半径は、受け部１８の曲率半径等と比べて十分に大きくされている。そして、この湾曲部３２は接点部２７を含む延出部２６の中間部に形成されている。具体的には湾曲部３２は、図１に示すＢ−Ｂ断面の部分からＡ−Ａ断面の部分（接点部２７の位置）にかけて少しずつ湾曲の度合いを増加させる形態とされている。一方、屈曲部２５、延出部２６の前端部及び後端部（自由端部３９）は全幅に亘って略同一高さで連なる形状とされている。   The extending portion 26 of the elastic contact piece 24 is formed with a curved portion 32 that curves so that its entire width approaches the insertion path 29 of the tab 61 from both ends in the width direction to the center (contact point portion 27). The curvature radius of the curved portion 32 is sufficiently larger than the curvature radius of the receiving portion 18 and the like. The curved portion 32 is formed at an intermediate portion of the extending portion 26 including the contact portion 27. Specifically, the bending portion 32 is configured to gradually increase the degree of bending from the portion of the BB cross section shown in FIG. 1 to the portion of the AA cross section (position of the contact portion 27). On the other hand, the bent portion 25, the front end portion and the rear end portion (free end portion 39) of the extending portion 26 are formed in a shape that is continuous at substantially the same height over the entire width.

次に、本実施形態の作用を説明する。
端子金具１０は図示しないコネクタハウジングに挿入され、相手端子金具６０は図示しない相手コネクタハウジングに挿入される。両コネクタハウジングが正規嵌合されるに伴い、図２に示すように、両端子金具１０、６０が正規深さで導通接続される。このとき、相手端子金具６０のタブ６１が挿入口１７を通して本体部１１内の挿入経路２９に挿入され、両受け本体部２１の頂部と接点部２７との間にタブ６１が三点支持状態で弾性的に保持される。タブ６１の本体部１１内への挿入途中では、タブ６１が湾曲部３２を点接触又は線接触状態で摺動し、弾性接触片２４が屈曲部２５を支点として下方へ撓み変形されるとともに、弾性接触片２４の延出部２６の先端部が底板部１４の内面に弾性的に当接するようになっている。 Next, the operation of this embodiment will be described.
The terminal fitting 10 is inserted into a connector housing (not shown), and the mating terminal fitting 60 is inserted into a mating connector housing (not shown). As both connector housings are properly fitted, both terminal fittings 10 and 60 are conductively connected at a normal depth as shown in FIG. At this time, the tab 61 of the mating terminal fitting 60 is inserted into the insertion path 29 in the main body 11 through the insertion port 17, and the tab 61 is supported in a three-point supported state between the top of the both receiving main body 21 and the contact portion 27. It is held elastically. During the insertion of the tab 61 into the main body 11, the tab 61 slides on the curved portion 32 in a point contact or line contact state, and the elastic contact piece 24 is bent and deformed downward with the bent portion 25 as a fulcrum. The distal end portion of the extending portion 26 of the elastic contact piece 24 is in elastic contact with the inner surface of the bottom plate portion 14.

以上説明したように本実施形態によれば、弾性接触片２４がその幅方向両端部から中央部に向けて本体部１１内におけるタブ６１の挿入経路２９側に近づくように湾曲する湾曲部３２を有しているから、仮に弾性接触片２４の幅寸法（湾曲部３２の弦方向に沿った寸法）が小さくとも、高いバネ反力を発生させることができる。したがって、端子金具１０が小型になっても、タブ６１との間に必要な接触荷重を得ることができる。   As described above, according to the present embodiment, the bending portion 32 that bends so that the elastic contact piece 24 approaches the insertion path 29 side of the tab 61 in the main body portion 11 from both ends in the width direction toward the center portion. Therefore, even if the width dimension of the elastic contact piece 24 (dimension along the chord direction of the curved portion 32) is small, a high spring reaction force can be generated. Therefore, even if the terminal metal fitting 10 becomes small, a necessary contact load can be obtained between the tab 61 and the terminal fitting 10.

また、湾曲部３２は弾性接触片２４のうちのタブ６１に接触する部分に形成され、湾曲部３２とタブ６１との接触面積は小さくなるため、弾性接触片２４とタブ６１との間の接触抵抗が低くなる。その結果、本体部１１内にタブ６１を低挿入力で挿入することができる。   Further, the curved portion 32 is formed in a portion of the elastic contact piece 24 that contacts the tab 61, and the contact area between the curved portion 32 and the tab 61 is reduced, so that the contact between the elastic contact piece 24 and the tab 61 is achieved. Resistance becomes low. As a result, the tab 61 can be inserted into the main body 11 with a low insertion force.

また、弾性接触片２４の撓み動作の支点となる屈曲部２５が湾曲部３２を構成せずに幅方向の全幅に亘って略同一高さで連なる形状とされているから、屈曲部２５における撓み動作の円滑性が確保される。さらに、底板部１４に弾性的に接触する弾性接触片２４の自由端部も湾曲部３２を構成せずに幅方向の全幅に亘って略同一高さで連なる形状とされているから、この弾性接触片２４の自由端部における撓み動作の円滑性が確保される。したがって、本体部１１内にタブ６１をいっそう低挿入力で挿入することができる。   In addition, since the bent portion 25 serving as a fulcrum for the bending operation of the elastic contact piece 24 does not form the curved portion 32 and has a shape that is continuous at substantially the same height over the entire width in the width direction, the bent portion 25 is bent. Smooth operation is ensured. Further, since the free end portion of the elastic contact piece 24 that elastically contacts the bottom plate portion 14 does not form the curved portion 32 and is formed in a shape that is continuous at substantially the same height over the entire width in the width direction. The smoothness of the bending operation at the free end of the contact piece 24 is ensured. Therefore, the tab 61 can be inserted into the main body 11 with a lower insertion force.
