Description

本発明は、端子及びコネクタに関するものである。   The present invention relates to a terminal and a connector.

従来、ケーブル等の電線をプリント回路基板等の回路基板に接続するために電線対基板コネクタが使用されている(例えば、特許文献1参照。)。このような電線対基板コネクタは、一方のコネクタが回路基板に実装され、ケーブルの端部に接続された他方のコネクタと嵌(かん)合する。   Conventionally, a wire-to-board connector has been used to connect an electric wire such as a cable to a circuit board such as a printed circuit board (for example, see Patent Document 1). In such a wire-to-board connector, one connector is mounted on a circuit board and is fitted (engaged) with the other connector connected to the end of the cable.

図13は従来のコネクタが有する端子を示す斜視図である。   FIG. 13 is a perspective view showing terminals of a conventional connector.

図において、862は図示されないケーブルの端部に接続される端子の結線部であり、端子の本体部861の後端に接続されている。前記結線部862は、ケーブルの絶縁被覆の上からケーブルに圧着されてケーブルを保持する被覆保持部862aと、ケーブルの先端部分において絶縁被覆が除去されたことによって露出している導電芯(しん)線に直接圧着されてケーブルを保持するとともに、導電芯線と電気的に接続される芯線保持部862bとを備える。また、前記本体部861は、左右両側端から立接する一対の折曲げ片861aを備え、略U字状又はコ字状の断面形状を備える。   In the drawing, reference numeral 862 denotes a terminal connection portion connected to an end portion of a cable (not shown), and is connected to the rear end of the terminal main body portion 861. The connection portion 862 includes a sheath holding portion 862a that is crimped to the cable from above the insulation coating of the cable to hold the cable, and a conductive core that is exposed by removing the insulation coating at the tip portion of the cable. A core wire holding portion 862b that is directly crimped to the wire to hold the cable and is electrically connected to the conductive core wire is provided. Further, the main body portion 861 includes a pair of bent pieces 861a standing from both left and right ends, and has a substantially U-shaped or U-shaped cross-sectional shape.

そして、前記本体部861の先端における左右両側端からは、細長い帯状の一対の接続部863が前方に延出する。左右の接続部863は、互いに平行に本体部861の先端から前方に延出しているが、途中で折返し反転させられているので、その先端は後方に向けて延出する。そして、左右の接続部863は、本体部861の先端に接続された基端部863aと、該基端部863aの先端から上方に向けて延出する折返し部863bと、該折返し部863bの先端から後方に向けて延出する反転部863cとを備える。なお、左右の反転部863cの先端は、円弧状の連結部865によって互いに連結されている。また、左右の反転部863cの側面には、互いに向合うように突出する接触凸部864が形成されている。   A pair of elongate strip-shaped connection portions 863 extend forward from the left and right ends at the tip of the main body portion 861. The left and right connecting portions 863 extend forward from the front end of the main body portion 861 in parallel to each other, but are turned upside down in the middle, so that the front ends extend rearward. The left and right connection portions 863 include a base end portion 863a connected to the distal end of the main body portion 861, a folded portion 863b extending upward from the distal end of the proximal end portion 863a, and a distal end of the folded portion 863b. And an inversion part 863c extending rearward. Note that the ends of the left and right reversing portions 863c are connected to each other by an arc-shaped connecting portion 865. In addition, contact convex portions 864 that protrude so as to face each other are formed on the side surfaces of the left and right inversion portions 863c.

前記端子は、ケーブルの端部に接続された状態で図示されない電線コネクタのハウジング内に装填(てん)される。そして、前記電線コネクタが回路基板に実装された図示されない基板コネクタと嵌合すると、前記端子は、基板コネクタが備える図示されない相手方端子と接触する。この場合、該相手方端子は板状の部材であり、端子に対して図において矢印Pで示される方向に相対的に移動し、左右の反転部863cの間に進入する。そして、板状の相手方端子は、表裏両面から反転部863cによって挟持され、これにより、端子と電気的に接触する。このとき、左右の反転部863cの接触凸部864が相手方端子の表裏両面に喰(くい)込むことにより、相手方端子と端子との接触が確実なものとなる。   The terminal is loaded into a housing of a wire connector (not shown) in a state of being connected to an end of the cable. When the wire connector is fitted to a board connector (not shown) mounted on the circuit board, the terminal comes into contact with a mating terminal (not shown) provided in the board connector. In this case, the counterpart terminal is a plate-like member, moves relative to the terminal in the direction indicated by the arrow P in the drawing, and enters between the left and right reversing portions 863c. Then, the plate-like mating terminal is sandwiched by the reversing portion 863c from both the front and back surfaces, thereby making electrical contact with the terminal. At this time, the contact protrusions 864 of the left and right reversing portions 863c bite the front and back surfaces of the counterpart terminal, thereby ensuring contact between the counterpart terminal and the terminal.

しかしながら、前記従来の端子においては、接続部863の反転部863cの先端及び連結部865が本体部861の折曲げ片861aの上方に位置するので、接続部863の捲(めく)れが発生してしまうことがある。例えば、基板コネクタとの嵌合作業等において、基板コネクタの部品や基板に実装されている他の部品のような他の部材の先端がコネクタに沿って、かつ、前方に向って、つまり、結線部862から接続部863に向って相対的に移動した場合、前記他の部材の先端が反転部863cの先端又は連結部865に引掛かることがある。すると、反転部863cの先端が上昇させられ、反転部863c全体が前方に向って回転させられ、捲れてしまう。   However, in the conventional terminal, the tip of the reversing portion 863c of the connecting portion 863 and the connecting portion 865 are located above the bent piece 861a of the main body portion 861, so that the connecting portion 863 is bent. May end up. For example, in a fitting operation with a board connector, the tip of another member such as a board connector part or another part mounted on the board is along the connector and directed forward, that is, connected. In the case of relative movement from the portion 862 toward the connecting portion 863, the tip of the other member may catch on the tip of the reversing portion 863c or the connecting portion 865. Then, the tip of the reversing part 863c is raised, and the whole reversing part 863c is rotated forward and drowned.

また、接続部863の反転部863cの先端及び連結部865が本体部861の折曲げ片861aの上方に位置するので、端子の高さ寸法が大きくなってしまい、端子の低背化が困難である。そのため、コネクタ全体の低背化も困難になってしまう。   In addition, since the tip of the reversing portion 863c of the connection portion 863 and the connecting portion 865 are located above the bent piece 861a of the main body portion 861, the height of the terminal becomes large, and it is difficult to reduce the height of the terminal. is there. This makes it difficult to reduce the height of the entire connector.

さらに、左右の反転部863cの先端を円弧状の連結部865によって互いに連結するので、相手方端子からの力を受けた場合に、反転部863cの各々は、独立に変位することができず、相互に束縛されてしまう。そのため、相手方端子から受けた力を適切に吸収することができず、相手方端子との接触を維持することできないときがある。   Furthermore, since the tips of the left and right reversing portions 863c are connected to each other by the arc-shaped connecting portion 865, each of the reversing portions 863c cannot be displaced independently when receiving a force from the counterpart terminal. It will be bound to. For this reason, the force received from the counterpart terminal cannot be properly absorbed, and sometimes the contact with the counterpart terminal cannot be maintained.

さらに、左右の反転部863cの先端を円弧状の連結部865によって互いに連結するので、端子の加工性が低下してしまう。前記端子は、通常、金属板に打抜き加工及び曲げ加工を施して製造するものであるところ、携帯電話機等小型の電子機器に装填されるコネクタにおいては端子の寸法が極めて微小なものとなり、先端が円弧状の連結部865によって連結された複雑な形状の反転部863cを含む左右の微小な接続部863を金属板から正確に打抜くことは困難である。   Furthermore, since the tips of the left and right reversing portions 863c are connected to each other by the arc-shaped connecting portion 865, the workability of the terminal is degraded. The terminal is usually manufactured by punching and bending a metal plate. However, in a connector loaded in a small electronic device such as a cellular phone, the terminal has a very small dimension, and the tip is It is difficult to accurately punch the left and right minute connection portions 863 including the inversion portions 863c having complicated shapes connected by the arc-shaped connection portions 865 from the metal plate.

本発明は、前記従来の問題点を解決して、本体部から前方に向けて延出するとともにその先端が相互に独立の左右一対の接続腕部を折返し反転させて前記先端を本体部に近接又は接触させることにより、接続腕部の強度が高く、嵌合の際に変形することがなく、かつ、独立に変位可能なので相手方端子との接触が確実であり、捲れが発生することがなく、低背化及び小型化することができ、加工性が高く、コストが低く、信頼性の高い端子及びコネクタを提供することを目的とする。   The present invention solves the above-mentioned conventional problems, extends forward from the main body, and turns the pair of left and right connecting arm parts independent of each other so that the front end is close to the main body. Or, by making contact, the strength of the connecting arm portion is high, it does not deform during fitting, and it can be displaced independently, so contact with the counterpart terminal is reliable, and no twisting occurs, An object of the present invention is to provide a highly reliable terminal and connector that can be reduced in height and size, have high workability, low cost, and high reliability.

そのために、本発明の端子においては、電線に接続される結線部と、該結線部の先端に接続された本体部と、該本体部の先端に接続され、相手方端子と接触する略平行な一対の接触腕部とを有し、各接触腕部は、前記本体部に接続された基端部と、該基端部の先端に接続され、後方に折返す折返し部と、該折返し部の先端から後方に向けて延出する反転部と、該反転部の先端に、曲げ部を介して接続された先端部とを備え、一対の接触腕部の先端部は、相互に独立であるとともに、前記本体部に近接又は接触し、該本体部によって変位を規制され、一対の接触腕部の間に進入する相手方端子と接触する。   Therefore, in the terminal of the present invention, a connection part connected to the electric wire, a main body part connected to the tip of the connection part, and a substantially parallel pair connected to the tip of the main body part and contacting the counterpart terminal Each contact arm portion, a base end portion connected to the main body portion, a turn-back portion connected to the tip end of the base end portion and folded back, and a tip end of the turn-up portion A reversing portion extending rearward and a tip portion connected to the tip of the reversing portion via a bending portion, and the tip portions of the pair of contact arm portions are independent from each other, It approaches or comes into contact with the main body, the displacement is regulated by the main body, and it comes into contact with a counterpart terminal that enters between a pair of contact arms.

本発明の他の端子においては、さらに、前記接触腕部の側面形状は、ほぼ閉じた周辺を備える。   In another terminal of the present invention, the side surface shape of the contact arm portion includes a substantially closed periphery.

本発明の更に他の端子においては、さらに、前記本体部の左右両側縁から本体部に略直交する方向に延出する側方規制部を含む位置規制部を更に有し、一対の接触腕部の先端部は左右の側方規制部の間に位置する。   In still another terminal of the present invention, the terminal further includes a position restricting portion including a side restricting portion extending in a direction substantially orthogonal to the main body portion from the left and right side edges of the main body portion, and a pair of contact arm portions The front end portion is located between the left and right side restricting portions.

本発明の更に他の端子においては、さらに、前記位置規制部は、側方規制部の先端から本体部に略直交する方向に延出する下方規制部を含み、一対の接触腕部の先端部は前記本体部と側方規制部との間に位置する。   In still another terminal of the present invention, the position restricting portion further includes a lower restricting portion extending in a direction substantially orthogonal to the main body portion from the tip end of the side restricting portion, and the tip end portions of the pair of contact arm portions Is located between the main body portion and the side regulating portion.

本発明の更に他の端子においては、さらに、一対の接触腕部の先端部は前記本体部と側方規制部とに挟持される。   In still another terminal according to the present invention, the distal ends of the pair of contact arm portions are sandwiched between the main body portion and the side regulating portion.

本発明のコネクタにおいては、前記電線に接続された本発明の端子と、該端子が装填されるハウジングとを有し、前記端子と接触する相手方端子、及び、前記ハウジングと嵌合する相手方ハウジングを備える相手方コネクタと嵌合する。   In the connector of the present invention, the terminal of the present invention connected to the electric wire, a housing in which the terminal is loaded, a mating terminal that contacts the terminal, and a mating housing that fits the housing Mates with mating connector.

本発明によれば、端子は、本体部から前方に向けて延出するとともにその先端が相互に独立の左右一対の接続腕部を折返し反転させて前記先端を本体部に近接又は接触させるようになっている。これにより、接続腕部の強度が高く、嵌合の際に変形することがなく、かつ、独立に変位可能なので相手方端子との接触が確実であり、捲れが発生することがなく、低背化及び小型化することができ、加工性を向上させ、コストを低下させ、信頼性を向上させることができる。   According to the present invention, the terminal extends forward from the main body portion, and the front end of the terminal is turned upside down so that the pair of left and right connecting arm portions are folded back to bring the front end close to or in contact with the main body portion. It has become.

図において、1は、本実施の形態のコネクタとしての電線コネクタであり、電線対基板コネクタにおける第1コネクタであり、複数の電線91を備えるケーブルの終端に接続される。また、101は、本実施の形態の電線対基板コネクタにおける相手方コネクタとしての基板コネクタであり、回路基板191の表面に実装され、前記電線コネクタ1と嵌合する。   In the figure, reference numeral 1 denotes an electric wire connector as a connector of the present embodiment, which is a first connector in an electric wire-to-board connector, and is connected to a terminal end of a cable including a plurality of electric wires 91. Reference numeral 101 denotes a board connector as a mating connector in the wire-to-board connector of the present embodiment, which is mounted on the surface of the circuit board 191 and fits with the wire connector 1.

前記基板191は、例えば、パーソナルコンピュータ、携帯電話機、PDA(Personal Digital Assistant:個人用携帯情報端末)、デジタルカメラ、ビデオカメラ、音楽プレーヤ、ゲーム機、車両用ナビゲーション装置等の電子機器、デジタルテレビ、DVDプレーヤ等の家庭電化製品のような電気機器等に使用されるプリント回路基板や、フレキシブル回路基板(FPC:Flexible Printed Circuit)、フレキシブルフラットケーブル(FFC:Flexible Flat Cable)等と称される平板状ケーブルなどであり、いかなる種類のものであってもよく、ここでは、携帯電話機等の内部において、使用されるプリント回路基板であるものとして説明する。   The board 191 includes, for example, a personal computer, a mobile phone, a PDA (Personal Digital Assistant), a digital camera, a video camera, a music player, a game machine, an electronic device such as a vehicle navigation device, a digital television, A flat circuit board called a printed circuit board, a flexible circuit board (FPC: Flexible Printed Circuit), a flexible flat cable (FFC: Flexible Flat Cable), etc. used for electric appliances such as home appliances such as DVD players Any type of cable may be used, and here, description will be made assuming that the printed circuit board is used inside a mobile phone or the like.

なお、図に示される例において、電線91は3本であるが、該電線91の数は任意に変更することができ、例えば、1本又は2本であってもよいし、4本以上であってもよい。また、前記電線91は、金属等の導電性材料から成る導電芯線と、樹脂等の絶縁性材料から成り、前記導電芯線の周囲を被覆する絶縁被覆とを備える通常の導電線である。   In the example shown in the figure, the number of the electric wires 91 is three, but the number of the electric wires 91 can be arbitrarily changed. For example, one or two electric wires 91 may be used. There may be. The electric wire 91 is a normal conductive wire including a conductive core wire made of a conductive material such as metal and an insulating coating made of an insulating material such as resin and covering the periphery of the conductive core wire.

本実施の形態において、基板コネクタ101及び電線コネクタ1の各部の構成及び動作を説明するために使用される上、下、左、右、前、後等の方向を示す表現は、絶対的なものでなく相対的なものであり、基板コネクタ101及び電線コネクタ1が図に示される姿勢である場合に適切であるが、基板コネクタ101及び電線コネクタ1の姿勢が変化した場合には姿勢の変化に応じて変更して解釈されるべきものである。   In the present embodiment, expressions showing directions such as upper, lower, left, right, front, rear, etc. used for explaining the configuration and operation of each part of the board connector 101 and the wire connector 1 are absolute. However, the circuit board connector 101 and the wire connector 1 are appropriate when they are in the posture shown in the figure. However, when the posture of the board connector 101 and the wire connector 1 is changed, the posture changes. It should be interpreted accordingly.

そして、前記基板側端子161は、互いに平行になるように前記ピッチで配列され、各々の本体部が、前記先端壁部115に形成されたスリット状の空間である端子保持部116内に収容されて保持される。また、前記基板側端子161の接触部164は、前記先端壁部115から後方に延出する。前記接触部164は、略矩形の板状部材であり、図2に示されるように、先端壁部115から後方に延出するとともに、底壁部112から上方に延出するように配設される。なお、前記基板側端子161のソルダーテール部162は、図1に示されるように、その先端が先端壁部115の下端から先端方向に延出し、回路基板191に形成された図示されない信号線、コンタクトパッド、端子等の接続部材に、はんだ付等によって電気的に接続される。   The board-side terminals 161 are arranged at the pitch so as to be parallel to each other, and each main body portion is accommodated in a terminal holding portion 116 which is a slit-like space formed in the tip wall portion 115. Held. Further, the contact portion 164 of the board-side terminal 161 extends backward from the tip wall portion 115. The contact portion 164 is a substantially rectangular plate-like member, and is disposed so as to extend rearward from the tip wall portion 115 and upward from the bottom wall portion 112 as shown in FIG. The As shown in FIG. 1, the solder tail portion 162 of the board-side terminal 161 has a tip extending from the lower end of the tip wall portion 115 in the tip direction, and a signal line (not shown) formed on the circuit board 191. It is electrically connected to connection members such as contact pads and terminals by soldering or the like.

一方、電線コネクタ1は、合成樹脂等の絶縁性材料によって一体的に形成され、前記基板コネクタ101の基板側ハウジング111と嵌合するハウジングとしての電線側ハウジング11と、該電線側ハウジング11に装填された金属製の端子61とを有する。そして、前記電線コネクタ1は、概略、扁平な直方体形状を備え、その下面が基板コネクタ101の上面に対向するような姿勢で上方から基板コネクタ101に挿入されて嵌合される。すなわち、基板コネクタ101に垂直嵌合される。   On the other hand, the electric wire connector 1 is integrally formed of an insulating material such as a synthetic resin, and is loaded into the electric wire side housing 11 as a housing that fits with the substrate side housing 111 of the board connector 101. The metal terminal 61 is made. The electric wire connector 1 has a substantially flat rectangular parallelepiped shape, and is inserted into and fitted into the board connector 101 from above in such a posture that its lower surface faces the upper surface of the board connector 101. That is, it is vertically fitted to the board connector 101.

図に示されるように、電線側ハウジング11は、直方体形状の部材であって、略矩形の平板状の天板部12と、該天板部12と平行で略矩形の平板状の底板部14と、天板部12及び底板部14の先端側の縁を連結し、天板部12及び底板部14に対して垂直な略矩形の平板状の先端部15と、前記天板部12と平行で、天板部12及び底板部14の後端側の縁を連結し、天板部12及び底板部14に対して垂直な略矩形の平板状の後端部16と、天板部12及び底板部14の左右両側の縁を連結し、天板部12及び底板部14に対して垂直な略矩形の平板状の一対の側壁部17とを有する。   As shown in the drawing, the electric wire side housing 11 is a rectangular parallelepiped member, and is a substantially rectangular flat plate top plate portion 12 and a substantially rectangular flat plate bottom plate portion 14 parallel to the top plate portion 12. And a top end 15 of a substantially rectangular shape that is perpendicular to the top plate 12 and the bottom plate 14, and is parallel to the top plate 12.

なお、該側壁部17の外側側壁には、外方に突出するロック部18が形成されている。電線コネクタ1が基板コネクタ101と嵌合する際に、前記ロック部18が基板側ハウジング111の側壁部117と係合することによって電線コネクタ1と基板コネクタ101とをロックする。   A lock portion 18 that protrudes outward is formed on the outer side wall of the side wall portion 17. When the electric wire connector 1 is fitted to the board connector 101, the lock part 18 is engaged with the side wall part 117 of the board side housing 111 to lock the electric wire connector 1 and the board connector 101.

また、前記電線側ハウジング11は、各電線91の先端部が挿入されるとともに、電線91に接続された端子61の各々を収容して保持する空間である端子収容部13を備える。該端子収容部13の各々は、底板部14の先端寄りの部分から先端部15にかけて連続して形成されたスリット状の相手方端子挿入開口13aと、後端部16に形成された矩形状の電線挿入開口13bとを備える。   In addition, the electric wire side housing 11 includes a terminal accommodating portion 13 that is a space for accommodating and holding each of the terminals 61 connected to the electric wires 91 while the distal end portion of each electric wire 91 is inserted. Each of the terminal accommodating portions 13 includes a slit-like counterpart terminal insertion opening 13 a formed continuously from a portion near the tip of the bottom plate portion 14 to the tip portion 15, and a rectangular electric wire formed at the rear end portion 16. And an insertion opening 13b.

そして、各端子収容部13内に電線91の先端部に接続された端子61が収容されると、図2に示されるように、電線91が電線コネクタ1の後方から対応する電線挿入開口13bに挿入された状態となり、各端子61の本体部63及び該本端部63の先端に接続された接触腕部64は各端子収容部13の外方に露出しない。なお、前記本体部63から切起こされた係止片部67は、電線側ハウジング11の天板部12に形成された溝状の係止開口部12a内に露出して、該係止開口部12aの後側壁と係合する。   And if the terminal 61 connected to the front-end | tip part of the electric wire 91 is accommodated in each terminal accommodating part 13, as FIG. 2 shows, the electric wire 91 will be in the corresponding electric wire insertion opening 13b from the back of the electric wire connector 1. As shown in FIG. The main body portion 63 of each terminal 61 and the contact arm portion 64 connected to the tip of the main end portion 63 are not exposed to the outside of each terminal accommodating portion 13. The locking piece 67 cut and raised from the main body 63 is exposed in a groove-shaped locking opening 12a formed in the top plate 12 of the electric wire side housing 11, and the locking opening 67 12a is engaged with the rear side wall.

前記端子収容部13、相手方端子挿入開口13a及び端子61の接触腕部64は、基板コネクタ101の基板側端子161における接触部164のピッチ及び配列態様に対応するように配列される。   The terminal accommodating portion 13, the counterpart terminal insertion opening 13 a, and the contact arm portion 64 of the terminal 61 are arranged so as to correspond to the pitch and arrangement of the contact portions 164 in the board-side terminal 161 of the board connector 101.

次に、前記端子61の構成について詳細に説明する。   Next, the configuration of the terminal 61 will be described in detail.

図4は本発明の第1の実施の形態における端子を示す斜視図、図5は本発明の第1の実施の形態における端子を示す四面図、図6は本発明の第1の実施の形態における端子右半分を示す斜視断面図である。なお、図5において(a)は上面図、(b)は正面図、(c)は下面図、(d)は側面図である。   FIG. 4 is a perspective view showing a terminal in the first embodiment of the present invention, FIG. 5 is a four-view diagram showing the terminal in the first embodiment of the present invention, and FIG. 6 is a first embodiment of the present invention. It is a perspective sectional view showing the terminal right half in. 5A is a top view, FIG. 5B is a front view, FIG. 5C is a bottom view, and FIG. 5D is a side view.

端子61は、金属板に打抜き加工、曲げ加工等の加工を施して製造されたものであり、本体部63と、該本体部63の後端に接続された結線部62と、前記本体部63の先端に接続された左右一対の接触腕部64とを有し、電線91の終端、すなわち、先端に接続される。   The terminal 61 is manufactured by performing a punching process, a bending process, or the like on a metal plate, and includes a main body part 63, a connection part 62 connected to the rear end of the main body part 63, and the main body part 63. A pair of left and right contact arm portions 64 connected to the tip of the wire 91 and connected to the terminal end of the electric wire 91, that is, the tip.

なお、図4及び6においては、端子61の下面側が上方を向いて示されている。また、図4においては、図示の都合上、電線91の先端部分であって端子61に接続される部分の図示が省略されている。   4 and 6, the lower surface side of the terminal 61 is shown facing upward. Further, in FIG. 4, for the convenience of illustration, illustration of the tip portion of the electric wire 91 and the portion connected to the terminal 61 is omitted.

そして、前記結線部62は、電線91の絶縁被覆の上から電線91に圧着されて電線91を保持する被覆保持部62aと、電線91の先端部分において絶縁被覆が除去されたことによって露出している導電芯線に直接圧着されて電線91を保持するとともに、導電芯線と電気的に接続される芯線保持部62bとを備える。前記被覆保持部62a及び芯線保持部62bは、結線部62の左右両側縁から下方に延出し、その先端が折曲げられて電線91及び導電芯線に圧着される。なお、図4〜6において、前記被覆保持部62a及び芯線保持部62bの形状は、既に曲げ加工が施され、電線91及び導電芯線に圧着された状態の形状である。   And the said connection part 62 is exposed by crimping | bonding to the electric wire 91 from the upper side of the insulation coating of the electric wire 91, and hold | maintaining the electric wire 91, and the insulation coating was removed in the front-end | tip part of the electric wire 91. And a core wire holding portion 62b that is directly crimped to the conductive core wire to hold the electric wire 91 and is electrically connected to the conductive core wire. The sheath holding portion 62a and the core wire holding portion 62b extend downward from the left and right side edges of the connection portion 62, and their tips are bent and are crimped to the electric wire 91 and the conductive core wire. 4-6, the shape of the said covering holding | maintenance part 62a and the core wire holding | maintenance part 62b is a shape of the state already bent and crimped | bonded to the electric wire 91 and the conductive core wire.

また、前記本体部63は、その中央部分から切起こされて形成された係止片部67を備える。該係止片部67は、その基端が本体部63に接続され、その自由端である先端が斜め上後方を向くように、延出するカンチレバー状の部材である。そして、係止片部67は、その先端が電線側ハウジング11の係止開口部12aの後側壁と係合することによって、電線側ハウジング11の端子収容部13内に収容された端子61が端子収容部13から抜出ることを防止する。なお、端子61は、電線91の先端部分に接続された状態で、電線側ハウジング11の後方から、後端部16に形成された矩形状の電線挿入開口13bを通して、端子収容部13内に挿入されることによって、電線側ハウジング11に装填される。   The main body 63 includes a locking piece 67 formed by being cut and raised from the central portion thereof. The locking piece portion 67 is a cantilever-like member that extends so that the base end thereof is connected to the main body portion 63 and the distal end that is the free end faces obliquely upward and rearward. The engaging piece 67 is engaged with the rear side wall of the engaging opening 12a of the electric wire side housing 11 so that the terminal 61 accommodated in the terminal accommodating portion 13 of the electric wire side housing 11 is a terminal. Pulling out from the accommodating portion 13 is prevented. The terminal 61 is inserted into the terminal accommodating portion 13 from the rear side of the electric wire side housing 11 through the rectangular electric wire insertion opening 13b formed in the rear end portion 16 while being connected to the distal end portion of the electric wire 91. As a result, the electric wire side housing 11 is loaded.

前記接触腕部64は、それぞれ、細長い帯状又は棒状の部材であり、本体部63の先端縁から前方に延出するが、途中で折返し反転させられているので、その先端は後方に向けて延出する。そして、左右の接触腕部64は、各々、本体部63の先端に接続された基端部64aと、該基端部64aの先端から下方に向けて湾曲し、後方に折返すように半円状に湾曲した折返し部64bと、該折返し部64bの先端から後方に向けて延出する反転部64cとを備える。前記基端部64aと反転部64cとは、ほぼ平行であり、折返し部64bによって接続されることにより、略U字状の側面形状を備える。   Each of the contact arm portions 64 is an elongated belt-like or rod-like member, and extends forward from the front end edge of the main body portion 63, but is turned upside down in the middle, so that the front end extends rearward. Put out. The left and right contact arm portions 64 are each a base end portion 64a connected to the tip end of the main body portion 63, a semicircle so as to bend downward from the tip end of the base end portion 64a and to be folded back. And a reversing portion 64c that extends rearward from the tip of the folding portion 64b. The base end portion 64a and the reversing portion 64c are substantially parallel to each other, and are connected by a folded portion 64b to have a substantially U-shaped side shape.

さらに、前記反転部64cの先端には、それぞれ、略S字状の側面形状を備える曲げ部としてのクランク部64eを介して、先端部としての被保持部64fが接続されている。該被保持部64fは、前記反転部64cとほぼ平行であるが、該反転部64cよりも上方に位置し、本体部63に近接又は接触している。つまり、左右の被保持部64fの上面は、それぞれ、本体部63に近接又は当接している。これにより、各接触腕部64全体の側面形状は、略矩形又は長円形のほぼ閉じた周辺を備えるものとなる。したがって、各接触腕部64の変形に対する強度は、極めて高いものとなる。   Further, a held portion 64f as a tip portion is connected to the tip of the reversing portion 64c via a crank portion 64e as a bending portion having a substantially S-shaped side shape. The held portion 64f is substantially parallel to the reversing portion 64c, but is positioned above the reversing portion 64c and is close to or in contact with the main body portion 63. That is, the upper surfaces of the left and right held portions 64f are close to or in contact with the main body portion 63, respectively. Thereby, the side shape of each contact arm portion 64 as a whole is provided with a substantially rectangular or oval substantially closed periphery. Therefore, the strength against deformation of each contact arm portion 64 is extremely high.

さらに、左右の被保持部64fは、相互に分離されているので、互いに独立に変位することができ、これにより、左右の反転部64c及び接触腕部64全体が互いに独立に変位することができる。   Furthermore, since the left and right held parts 64f are separated from each other, they can be displaced independently of each other, and thereby the left and right reversing parts 64c and the entire contact arm part 64 can be displaced independently of each other. .

また、前記本体部63の左右両側縁には位置規制部66が接続されている。該位置規制部66は、左右両側縁から延出する帯板部材を折曲げて形成され、本体部63の左右両側縁から本体部63に略直交する方向としての下方に延出する側方規制部66bと、該側方規制部66bの先端から本体部63に略平行に内方に延出する下方規制部66aとを備える。そして、左右の被保持部64fは、本体部63、側方規制部66b及び下方規制部66aによって囲まれた空間内に位置し、これにより、左右の反転部64cの先端である被保持部64fの上下左右方向への変位が規制される。   In addition, position restricting portions 66 are connected to the left and right side edges of the main body portion 63. The position restricting portion 66 is formed by bending a band plate member extending from the left and right side edges, and is a side restriction extending downward from the left and right side edges of the main body 63 as a direction substantially perpendicular to the main body 63. A portion 66b and a lower restricting portion 66a extending inward from the tip of the side restricting portion 66b substantially in parallel to the main body 63. The left and right held portions 64f are located in a space surrounded by the main body portion 63, the side restricting portions 66b, and the lower restricting portions 66a, whereby the held portions 64f that are the tips of the left and right reversing portions 64c. Displacement in the vertical and horizontal directions is restricted.

つまり、反転部64cが上向きの力を受けても、被保持部64fは、本体部63に接触すると、それ以上上方に変位することが防止される。また、反転部64cが下向きの力を受けても、被保持部64fは、下方規制部66aに接触すると、それ以上下方に変位することが防止される。さらに、反転部64cが外向きの力を受けても、被保持部64fは、側方規制部66bに接触すると、それ以上外方に変位することが防止される。なお、反転部64cが内向きの力を受けた場合には、左右の被保持部64fは、相互に接触するので、それ以上内方に変位することが防止される。   That is, even if the reversing part 64 c receives an upward force, the held part 64 f is prevented from being displaced further upward when it comes into contact with the main body part 63. Even if the reversing portion 64c receives a downward force, the held portion 64f is prevented from being further displaced downward when it comes into contact with the lower regulating portion 66a. Furthermore, even if the reversing part 64c receives an outward force, the held part 64f is prevented from further outward displacement when it comes into contact with the side regulating part 66b. When the reversing portion 64c receives an inward force, the left and right held portions 64f are in contact with each other, and thus are prevented from being displaced further inward.

また、左右の反転部64cの先端である被保持部64fが本体部63及び位置規制部66によって囲まれた空間内に位置するので、電線91の先端部分に接続された端子61を端子収容部13内に挿入して電線側ハウジング11に装填する作業等の際に、前記被保持部64fが他の部品、工具等の他の部材に引掛かることがない。したがって、反転部64cが捲れてしまうことがない。   In addition, since the held portion 64f that is the tip of the left and right reversing portions 64c is located in the space surrounded by the main body portion 63 and the position restricting portion 66, the terminal 61 connected to the tip portion of the electric wire 91 is connected to the terminal accommodating portion. The held portion 64f is not caught by other parts, tools, or other members when inserted into the wire 13 and loaded into the electric wire side housing 11 or the like. Therefore, the inversion part 64c is not drowned.

さらに、前記端子61全体が電線側ハウジング11の端子収容部13内に収容され、周囲を取囲まれているので、電線コネクタ1と基板コネクタ101との嵌合作業等の際に、前記被保持部64fが基板コネクタ101の部品、回路基板191に実装されている他の部品、工具等の他の部材に引掛かることがない。したがって、反転部64cが捲れてしまうことがない。さらに、塵埃(じんあい)等の異物が左右の接触腕部64の間に進入することがないので、異物の噛(か)みこみに起因する接触腕部64の変形が生じることもない。   Further, since the entire terminal 61 is accommodated in the terminal accommodating portion 13 of the electric wire side housing 11 and surrounded by the periphery, the object to be held is engaged during the fitting operation of the electric wire connector 1 and the board connector 101 or the like. The portion 64f is not caught by other components such as components of the board connector 101, other components mounted on the circuit board 191, and tools. Therefore, the inversion part 64c is not drowned. Further, since foreign matter such as dust does not enter between the left and right contact arm portions 64, the contact arm portion 64 is not deformed due to the biting of foreign matter.

また、被保持部64fが下方規制部66aより上方に位置するので、反転部64cと基端部64aとの間隔を狭くすることできる。すなわち、接触腕部64の高さ方向の寸法を短くすることができる。したがって、端子61を低背化することができ、電線コネクタ1全体を低背化することができる。左右の反転部64cの先端である被保持部64fが相互に分離されていることで、左右の接触腕部64の加工性が高くなり、端子61全体の加工性が高くなる。   Further, since the held portion 64f is located above the lower restricting portion 66a, the interval between the reversing portion 64c and the base end portion 64a can be reduced. That is, the dimension of the contact arm portion 64 in the height direction can be shortened. Therefore, the terminal 61 can be reduced in height, and the entire wire connector 1 can be reduced in height. Since the held portions 64f that are the tips of the left and right reversing portions 64c are separated from each other, the workability of the left and right contact arm portions 64 is improved, and the workability of the entire terminal 61 is improved.

さらに、左右の接触腕部64の加工性が高いので、各反転部64cの先端に、複雑な形状を備えるクランク部64eを介して、被保持部64fが接続することが可能となり、これにより、被保持部64fを反転部64cよりも上方に位置させて、本体部63に近接又は接触させることができる。したがって、接触腕部64全体の側面形状を閉じた周辺を備えるものとして、接触腕部64の変形に対する強度を高くするとことが可能となるとともに、特に、反転部64cの上方への変位を効果的に防止することができる。   Furthermore, since the workability of the left and right contact arm portions 64 is high, the held portion 64f can be connected to the tip of each reversing portion 64c via a crank portion 64e having a complicated shape. The held portion 64f can be positioned above the reversing portion 64c and can be brought close to or in contact with the main body portion 63. Therefore, it is possible to increase the strength against deformation of the contact arm portion 64 by providing the periphery where the side shape of the entire contact arm portion 64 is closed, and in particular, it is possible to effectively displace the reversing portion 64c upward. Can be prevented.

なお、左右の反転部64cの内側の側面には、互いに向合うように突出する接触凸部64dが形成されている。また、左右の接触腕部64の間は、電線コネクタ1が基板コネクタ101と嵌合すると、相手方端子としての基板側端子161の接触部164が進入する空間である相手方端子進入部65となっている。該相手方端子進入部65に進入した板状の接触部164は、左右両面から接触腕部64によって挟持され、これにより、基板側端子161と端子61とが電気的に接触する。このとき、左右の反転部64cの接触凸部64dが接触部164の両面に喰込むことにより、基板側端子161と端子61との接触が確実なものとなる。   In addition, contact convex portions 64d that protrude so as to face each other are formed on the inner side surfaces of the left and right inversion portions 64c. Further, between the left and right contact arm portions 64, when the electric wire connector 1 is fitted to the board connector 101, a counterpart terminal entry portion 65 that is a space into which the contact portion 164 of the board side terminal 161 as the counterpart terminal enters. Yes. The plate-like contact part 164 that has entered the counterpart terminal entry part 65 is sandwiched by the contact arm part 64 from both the left and right sides, whereby the board-side terminal 161 and the terminal 61 are in electrical contact. At this time, the contact convex portions 64d of the left and right reversing portions 64c bite into both surfaces of the contact portion 164, so that the contact between the board-side terminal 161 and the terminal 61 is ensured.

このように、接触凸部64dが接触部164の両面に喰込むので、左右の反転部64cは、基板側端子161の接触部164から大きな反力を受けることとなる。しかし、前述のように、反転部64cの先端である被保持部64fの上下左右方向への変位が規制されているので、接触部164から大きな反力を受けても、各反転部64cが大きく変位することがなく、接触部164との接触を確実に維持することができる。   Thus, since the contact convex part 64d bites into both surfaces of the contact part 164, the left and right reversing parts 64c receive a large reaction force from the contact part 164 of the board-side terminal 161. However, as described above, since the displacement of the held portion 64f, which is the tip of the reversing portion 64c, is restricted in the vertical and horizontal directions, each reversing portion 64c is large even if it receives a large reaction force from the contact portion 164. The contact with the contact portion 164 can be reliably maintained without being displaced.

また、前述のように、接触腕部64全体の側面形状が略矩形又は長円形のほぼ閉じた周辺を備え、接触腕部64の変形に対する強度が極めて高いので、接触部164から大きな力を受けても、接触腕部64の各部は大きく変位することがない。特に、接触部164は接触腕部64に対して相対的に下方から相手方端子進入部65に進入するので、反転部64cは、接触部164から大きな上向きの力を受けることとなる。しかし、被保持部64fが本体部63に近接又は接触しているので、反転部64cは、上方に大きく変位することがない。   Further, as described above, the contact arm portion 64 as a whole has a substantially rectangular or oval side surface with a substantially closed periphery, and the strength against deformation of the contact arm portion 64 is extremely high. However, each part of the contact arm part 64 is not greatly displaced. In particular, the contact portion 164 enters the counterpart terminal entry portion 65 from below relative to the contact arm portion 64, so that the reversing portion 64 c receives a large upward force from the contact portion 164. However, since the held portion 64f is close to or in contact with the main body portion 63, the reversing portion 64c is not greatly displaced upward.

さらに、左右の被保持部64fが互いに独立なので、左右の反転部64c及び接触腕部64全体は、互いに独立に変位することができる。したがって、基板側端子161から受ける力の大きさや方向が左右の接触腕部64で不均一であっても、左右の接触腕部64は、互いに独立に変位して前記力を適切に吸収することができ、基板側端子161との接触状態を維持することができる。   Furthermore, since the left and right held portions 64f are independent from each other, the left and right inversion portions 64c and the entire contact arm portion 64 can be displaced independently of each other. Therefore, even if the magnitude and direction of the force received from the board-side terminal 161 is not uniform between the left and right contact arm portions 64, the left and right contact arm portions 64 are displaced independently from each other and appropriately absorb the force. The contact state with the board side terminal 161 can be maintained.

次に、前記電線コネクタ1を基板コネクタ101に嵌合する動作について説明する。   Next, an operation for fitting the wire connector 1 to the board connector 101 will be described.

図7は本発明の第1の実施の形態における電線対基板コネクタの嵌合した状態を示す上面図、図8は本発明の第1の実施の形態における電線対基板コネクタの嵌合した状態を示す第1の側断面図であって図7のA−A矢視断面図、図9は本発明の第1の実施の形態における電線対基板コネクタの嵌合した状態を示す第2の側断面図であって図7のB−B矢視断面図である。   FIG. 7 is a top view showing a state in which the wire-to-board connector is fitted in the first embodiment of the present invention, and FIG. 8 is a state in which the wire-to-board connector is fitted in the first embodiment of the present invention. FIG. 9 is a first side sectional view showing a sectional view taken along line AA in FIG. 7, and FIG. 9 is a second side sectional view showing a state in which the wire-to-board connector is fitted in the first embodiment of the present invention. It is a figure and it is BB arrow sectional drawing of FIG.

電線コネクタ1を回路基板191に実装された基板コネクタ101に嵌合する場合には、電線コネクタ1をオペレータが手指等によって操作して、図1及び2に示されるように、電線コネクタ1の底板部14が基板コネクタ101の底壁部112に向合うように位置させる。また、電線コネクタ1の先端部15が基板コネクタ101の先端壁部115と同一方向を向くように、電線コネクタ1の向きが調整される。そして、電線コネクタ1を回路基板191に対して垂直に移動させ、電線コネクタ1の底板部14を基板コネクタ101の基板側ハウジング111の底壁部112、先端壁部115及び側壁部117によって周囲を画定される凹部に上方から挿入し、図7〜9に示されるように、電線コネクタ1を基板コネクタ101に嵌合させる。   When fitting the wire connector 1 to the board connector 101 mounted on the circuit board 191, the operator operates the wire connector 1 with fingers or the like, and the bottom plate of the wire connector 1 as shown in FIGS. 1 and 2. The portion 14 is positioned so as to face the bottom wall portion 112 of the board connector 101. Further, the orientation of the electric wire connector 1 is adjusted so that the distal end portion 15 of the electric wire connector 1 faces the same direction as the distal end wall portion 115 of the board connector 101. Then, the electric wire connector 1 is moved vertically with respect to the circuit board 191, and the bottom plate portion 14 of the electric wire connector 1 is surrounded by the bottom wall portion 112, the tip wall portion 115 and the side wall portion 117 of the substrate side housing 111 of the board connector 101. The wire connector 1 is fitted into the board connector 101 as shown in FIGS.

この際、基板コネクタ101の基板側端子161における接触部164が、電線コネクタ1に対して相対的に上昇し、電線側ハウジング11の底板部14の下方から、相手方端子挿入開口13aを通って、端子収容部13内に進入する。なお、該端子収容部13内において、底板部14の先端寄りの部分に形成された相手方端子挿入開口13aの上方に対応する部位には、接触腕部64の基端部64a、折返し部64b及び反転部64cが位置する。したがって、相手方端子挿入開口13aを通って端子収容部13内に進入した接触部164は、下方から左右の接触腕部64の間の相手方端子進入部65に進入する。   At this time, the contact portion 164 in the board-side terminal 161 of the board connector 101 rises relatively with respect to the electric wire connector 1 and passes from the lower side of the bottom plate portion 14 of the electric wire side housing 11 through the mating terminal insertion opening 13a. It enters into the terminal accommodating part 13. In the terminal accommodating portion 13, the base end portion 64 a of the contact arm portion 64, the folded portion 64 b, and the portion corresponding to the upper portion of the counterpart terminal insertion opening 13 a formed in the portion near the distal end of the bottom plate portion 14 are provided. The inversion part 64c is located. Therefore, the contact portion 164 that has entered the terminal accommodating portion 13 through the counterpart terminal insertion opening 13a enters the counterpart terminal entry portion 65 between the left and right contact arm portions 64 from below.

そして、前記接触部164が左右の接触腕部64によって挟持されるので、基板側端子161と端子61とが電気的に接触する。このとき、左右の反転部64cの接触凸部64dが接触部164の両面に喰込むので、基板側端子161と端子61とは、確実に接触する。また、反転部64cが大きく変位しないので、反転部64cと接触部164との接触が確実に維持される。これにより、電線91の導電線が、端子61及び基板側端子161を介して、回路基板191の接続部材に電気的に確実に接続される。   Since the contact portion 164 is sandwiched between the left and right contact arm portions 64, the board-side terminal 161 and the terminal 61 are in electrical contact. At this time, since the contact convex portions 64d of the left and right reversing portions 64c bite into both surfaces of the contact portion 164, the board-side terminal 161 and the terminal 61 are reliably in contact with each other. Further, since the reversing portion 64c is not greatly displaced, the contact between the reversing portion 64c and the contact portion 164 is reliably maintained. Thereby, the conductive wire of the electric wire 91 is electrically and reliably connected to the connection member of the circuit board 191 via the terminal 61 and the board-side terminal 161.

また、電線コネクタ1のロック部18が基板側ハウジング111の側壁部117と係合してロックされる。これにより、電線コネクタ1が基板コネクタ101から外れることが防止される。なお、ロックする際、オペレータは、ロック部材18を操作する必要がないので、電線コネクタ1と基板コネクタ101との嵌合操作を容易に行うことができる。なお、ロック部18と側壁部117とが係合したことによるクリック感を十分に感じることができるので、オペレータは、電線コネクタ1と基板コネクタ101との嵌合が完了したことを正確に認識することができる。   Further, the lock portion 18 of the electric wire connector 1 is engaged and locked with the side wall portion 117 of the board side housing 111. This prevents the electric wire connector 1 from being detached from the board connector 101. In addition, since it is not necessary for the operator to operate the lock member 18 when locking, the fitting operation of the electric wire connector 1 and the board connector 101 can be easily performed. In addition, since the click feeling due to the engagement of the lock portion 18 and the side wall portion 117 can be sufficiently felt, the operator accurately recognizes that the fitting between the wire connector 1 and the board connector 101 is completed. be able to.

このように、本実施の形態において、反転部64cの先端に接続された被保持部64fが相互に独立であり、かつ、本体部63に近接又は接触している。そして、被保持部64fが相互に独立なので、左右の反転部64c及び接触腕部64全体は、互いに独立に変位することができる。   Thus, in the present embodiment, the held parts 64f connected to the tip of the reversing part 64c are independent from each other and are close to or in contact with the main body part 63. And since the to-be-held part 64f is mutually independent, the right-and-left inversion part 64c and the contact arm part 64 whole can be displaced mutually independently.

したがって、基板側端子161から受ける力の大きさや方向が左右の接触腕部64で不均一であっても、左右の接触腕部64は、互いに独立に変位して前記力を適切に吸収することができ、基板側端子161との接触状態を維持することができる。基板側端子161自体の寸法公差、基板側端子161の基板側ハウジング111への取付公差等の問題や、嵌合作業における電線コネクタ1と基板コネクタ101との姿勢変化により、左右の接触腕部64の間の相手方端子進入部65へ進入する基板側端子161の接触部164の姿勢等の状態は、必ずしも一様ではなく、これにより、左右の接触腕部64が接触部164から受ける力の大きさや方向は、不均一になりやすい。そのため、仮に左右の被保持部64fが連結されていると、例えば、一方の接触腕部64が接触部164から受けた力によって変位した場合、他方の接触腕部64もそれに引きずられて変位するので、接触部164との接触が維持されないおそれがある。それに対し、本実施の形態においては、左右の接触腕部64が互いに独立に変位可能なので、一方の接触腕部64の変位に他方の接触腕部64が引きずられることがなく、基板側端子161の接触部164との接触を確実に維持することができる。   Therefore, even if the magnitude and direction of the force received from the board-side terminal 161 is not uniform between the left and right contact arm portions 64, the left and right contact arm portions 64 are displaced independently from each other and appropriately absorb the force. The contact state with the board side terminal 161 can be maintained. Due to problems such as dimensional tolerance of the board-side terminal 161 itself, mounting tolerance of the board-side terminal 161 to the board-side housing 111, and changes in the posture of the wire connector 1 and the board connector 101 during the fitting operation, the left and right contact arm portions 64 The state of the contact portion 164 of the board-side terminal 161 that enters the counterpart terminal entry portion 65 between them is not necessarily uniform, and thereby, the force that the left and right contact arm portions 64 receive from the contact portion 164 is large. The sheath direction tends to be uneven. Therefore, if the left and right held parts 64f are connected, for example, when one contact arm part 64 is displaced by the force received from the contact part 164, the other contact arm part 64 is also displaced by that. Therefore, the contact with the contact portion 164 may not be maintained. On the other hand, in the present embodiment, the left and right contact arm portions 64 can be displaced independently from each other, so that the displacement of one contact arm portion 64 does not drag the other contact arm portion 64, and the board-side terminal 161. The contact with the contact portion 164 can be reliably maintained.

また、被保持部64fが相互に独立なので、左右の接触腕部64の加工性が高く、かつ、左右の接触腕部64の加工性が高いので被保持部64fを反転部64cよりも上方に位置させて、本体部63に近接又は接触させることができる。したがって、接触腕部64全体の側面形状を閉じた周辺を備えるものとして、接触腕部64の変形に対する強度を高くすることが可能となるとともに、特に、反転部64cの上方への変位を効果的に防止することができる。また、反転部64cと基端部64aとの間隔を狭くすることでき、接触腕部64の高さ方向の寸法を短くすることができるので、端子61を低背化することができ、電線コネクタ1全体を低背化することができる。   Further, since the held portions 64f are independent from each other, the workability of the left and right contact arm portions 64 is high, and the workability of the left and right contact arm portions 64 is high, so the held portion 64f is positioned above the reversing portion 64c. The main body 63 can be brought close to or in contact with the main body 63. Therefore, it is possible to increase the strength against deformation of the contact arm portion 64 by providing the periphery where the side shape of the entire contact arm portion 64 is closed, and in particular, it is possible to effectively displace the reversing portion 64c upward. Can be prevented. Moreover, since the space | interval of the inversion part 64c and the base end part 64a can be narrowed and the dimension of the height direction of the contact arm part 64 can be shortened, the terminal 61 can be made low-profile, and an electric wire connector The whole 1 can be reduced in height.

さらに、被保持部64fが本体部63及び位置規制部66によって囲まれた空間内に位置するので、被保持部64fの上下左右方向への変位が規制される。したがって、電線コネクタ1と基板コネクタ101との嵌合の際に、接触部164から大きな力を受けても、接触腕部64の各部が大きく変位することがないので、接触部164との接触を確実に維持することができる。また、被保持部64fが他の部材に引掛かることがないので、反転部64cが捲れてしまうことがない。   Furthermore, since the held portion 64f is located in the space surrounded by the main body portion 63 and the position restricting portion 66, the displacement of the held portion 64f in the vertical and horizontal directions is restricted. Therefore, when the electric wire connector 1 and the board connector 101 are fitted, even if a large force is received from the contact portion 164, each portion of the contact arm portion 64 is not greatly displaced, so that the contact with the contact portion 164 is prevented. It can be reliably maintained. Further, since the held portion 64f is not caught by another member, the reversing portion 64c will not be twisted.

なお、本実施の形態においては、接触腕部64の内側の側面から互いに向合うように突出する接触凸部64dを、反転部64cのみに形成した例についてのみ説明したが、接触凸部64dは、基端部64aのみに形成してもよいし、反転部64c及び基端部64aの両方に形成してもよい。   In the present embodiment, only the example in which the contact convex portions 64d that protrude from the inner side surface of the contact arm portion 64 so as to face each other are formed only on the inversion portion 64c, but the contact convex portion 64d is Further, it may be formed only on the base end portion 64a, or may be formed on both the inversion portion 64c and the base end portion 64a.

次に、本発明の第2の実施の形態について説明する。なお、第1の実施の形態と同じ構造を有するものについては、同じ符号を付与することによってその説明を省略する。また、前記第1の実施の形態と同じ動作及び同じ効果についても、その説明を省略する。   Next, a second embodiment of the present invention will be described. In addition, about the thing which has the same structure as 1st Embodiment, the description is abbreviate | omitted by providing the same code | symbol. The description of the same operation and the same effect as those of the first embodiment is also omitted.

図10は本発明の第2の実施の形態における端子を示す斜視図である。   FIG. 10 is a perspective view showing a terminal in the second embodiment of the present invention.

本実施の形態においては、図10に示されるように、位置規制部66の下方規制部66aがプレス加工によって上方に、すなわち、本体部63に向けて押圧されている。したがって、図示されない被保持部64fは、下方規制部66aによって本体部63に押付けられている。   In the present embodiment, as shown in FIG. 10, the lower restricting portion 66 a of the position restricting portion 66 is pressed upward, that is, toward the main body 63. Accordingly, the held portion 64f (not shown) is pressed against the main body portion 63 by the lower restricting portion 66a.

なお、図10においては、前記第1の実施の形態において説明した図4と同様に、端子61の下面側が上方を向いて示され、被覆保持部62a及び芯線保持部62bの形状は、既に曲げ加工が施され、電線91及び導電芯線に圧着された状態の形状である。   In FIG. 10, similarly to FIG. 4 described in the first embodiment, the lower surface side of the terminal 61 is shown facing upward, and the shapes of the covering holding portion 62a and the core wire holding portion 62b are already bent. It is a shape in a state where it is processed and crimped to the electric wire 91 and the conductive core wire.

このように、左右の反転部64cの先端である被保持部64fは、本体部63及び下方規制部66aによって上下両側から挟持されている。したがって、反転部64cが上向き及び下向きの力を受けても、被保持部64fは上下に変位することがない。また、被保持部64fは、本体部63及び下方規制部66aによって上下から挟持されているので、横方向にも変位不能であるから、反転部64cが外向き及び内向きの力を受けても、変位することがない。   Thus, the held portion 64f, which is the tip of the left and right reversing portions 64c, is sandwiched from the upper and lower sides by the main body portion 63 and the lower restricting portion 66a. Therefore, even if the reversing part 64c receives upward and downward forces, the held part 64f does not move up and down. Further, since the held portion 64f is sandwiched from above and below by the main body portion 63 and the lower restricting portion 66a, it cannot be displaced in the lateral direction, so even if the reversing portion 64c receives outward and inward forces. No displacement.

このように、本実施の形態においては、被保持部64fが本体部63及び下方規制部66aによって挟持され、固定されている。したがって、接触腕部64の変形に対する強度がより高くなり、接触部164から大きな力を受けても、接触腕部64の各部が大きく変位することがないので、接触部164との接触を確実に維持することができる。   Thus, in the present embodiment, the held portion 64f is sandwiched and fixed by the main body portion 63 and the lower restricting portion 66a. Accordingly, the strength against deformation of the contact arm portion 64 is further increased, and even if a large force is received from the contact portion 164, each portion of the contact arm portion 64 is not greatly displaced, so that the contact with the contact portion 164 is ensured. Can be maintained.

また必要に応じて、下方規制部66aの曲げ加工量を、被保持部64fに近接もしくはわずかに接触する程度にし、被保持部64fが、上下方向に変位することはないが、前後左右方向には変位するように調整してもよい。   If necessary, the amount of bending of the lower restricting portion 66a is set to be close to or slightly in contact with the held portion 64f, and the held portion 64f is not displaced in the vertical direction, May be adjusted to be displaced.

なお、その他の点の構成、動作及び効果については、前記第1の実施の形態と同様であるので、その説明を省略する。   Since the configuration, operation, and effects of other points are the same as those in the first embodiment, description thereof is omitted.

次に、本発明の第3の実施の形態について説明する。なお、第1及び第2の実施の形態と同じ構造を有するものについては、同じ符号を付与することによってその説明を省略する。また、前記第1及び第2の実施の形態と同じ動作及び同じ効果についても、その説明を省略する。   Next, a third embodiment of the present invention will be described. In addition, about the thing which has the same structure as 1st and 2nd embodiment, the description is abbreviate | omitted by providing the same code | symbol. Also, the description of the same operations and effects as those of the first and second embodiments is omitted.

図11は本発明の第3の実施の形態における端子を示す斜視図である。   FIG. 11 is a perspective view showing a terminal in the third embodiment of the present invention.

本実施の形態においては、図11に示されるように、位置規制部66は、側方規制部66bのみを備え、下方規制部66aを備えていない。すなわち、下方規制部66aが省略されている。したがって、被保持部64fの下方向への変位は規制されていない。   In the present embodiment, as shown in FIG. 11, the position restricting portion 66 includes only the side restricting portion 66b and does not include the lower restricting portion 66a. That is, the downward restricting portion 66a is omitted. Therefore, the downward displacement of the held portion 64f is not restricted.

なお、図11においては、前記第1の実施の形態において説明した図4と同様に、端子61の下面側が上方を向いて示され、被覆保持部62a及び芯線保持部62bの形状は、既に曲げ加工が施され、電線91及び導電芯線に圧着された状態の形状である。   In FIG. 11, as in FIG. 4 described in the first embodiment, the lower surface side of the terminal 61 is shown facing upward, and the shapes of the covering holding portion 62a and the core wire holding portion 62b are already bent. It is a shape in a state where it is processed and crimped to the electric wire 91 and the conductive core wire.

このように、本実施の形態においては、下方規制部66aが省略されているので、位置規制部66に施す曲げ加工を簡略化することができる。したがって、端子61の加工が容易となり、生産性が向上する。なお、被保持部64fの下方向への変位が規制されていないので、反転部64cが下向きの力を受けた場合には反転部64cの変位が大きくなるが、基板側端子161の接触部164から反転部64cが受ける下向きの力は、上向きの力ほど大きくないと考えられる。したがって、実際上、反転部64cが下方向へ大きく変位することはない。   Thus, in the present embodiment, since the lower restricting portion 66a is omitted, the bending process applied to the position restricting portion 66 can be simplified. Therefore, processing of the terminal 61 becomes easy and productivity is improved. Since the downward displacement of the held portion 64f is not restricted, the displacement of the reversing portion 64c increases when the reversing portion 64c receives a downward force, but the contact portion 164 of the board-side terminal 161 increases. It is considered that the downward force received by the reversing portion 64c is not as great as the upward force. Therefore, in practice, the reversing portion 64c is not greatly displaced downward.

なお、その他の点の構成、動作及び効果については、前記第1の実施の形態と同様であるので、その説明を省略する。   Since the configuration, operation, and effects of other points are the same as those in the first embodiment, description thereof is omitted.

次に、本発明の第4の実施の形態について説明する。なお、第1〜第3の実施の形態と同じ構造を有するものについては、同じ符号を付与することによってその説明を省略する。また、前記第1〜第3の実施の形態と同じ動作及び同じ効果についても、その説明を省略する。   Next, a fourth embodiment of the present invention will be described. In addition, about the thing which has the same structure as the 1st-3rd embodiment, the description is abbreviate | omitted by providing the same code | symbol. Explanation of the same operations and effects as those of the first to third embodiments is also omitted.

図12は本発明の第4の実施の形態における端子を示す斜視図である。   FIG. 12 is a perspective view showing a terminal in the fourth embodiment of the present invention.

本実施の形態においては、図12に示されるように、反転部64cの先端には、クランク部64eに代えて、略L字状の側面形状を備える鉤(かぎ)部64gを介して、被保持部64fが接続されている。すなわち、反転部64cに先端部としての被保持部64fを接続する曲げ部として機能する部分が、本実施の形態においては、クランク部64eではなく、略L字状の側面形状を備える鉤部64gとなっている。そのため、前記被保持部64fは、反転部64c及び本体部63に対してほぼ垂直に上方に向けて延出する。そして、被保持部64fの先端は、本体部63に形成された保持用開口部68内に進入している。   In the present embodiment, as shown in FIG. 12, the tip of the reversing portion 64c is covered with a hook portion 64g having a substantially L-shaped side surface instead of the crank portion 64e. A holding part 64f is connected. That is, the portion that functions as a bending portion that connects the held portion 64f as the tip portion to the reversing portion 64c is not the crank portion 64e but a flange portion 64g having a substantially L-shaped side surface shape in the present embodiment. It has become. Therefore, the held portion 64f extends upward substantially perpendicularly to the reversing portion 64c and the main body portion 63. The tip of the held portion 64 f enters the holding opening 68 formed in the main body portion 63.

したがって、被保持部64fは、保持用開口部68によって前後左右方向への変位が規制される。なお、被保持部64fは、上下方向に大きく変位すると、その軸線が傾斜するので、前方又は後方の側面が保持用開口部68の前縁又は後縁に接触する。そのため、反転部64cが上下方向の力を受けた場合、被保持部64fの上下方向の変位は、保持用開口部68によってある程度の範囲で規制される。   Therefore, displacement of the held portion 64f in the front-rear and left-right directions is restricted by the holding opening 68. Note that when the held portion 64f is largely displaced in the vertical direction, the axis thereof is inclined, so that the front or rear side surface contacts the front edge or the rear edge of the holding opening 68. Therefore, when the reversing portion 64 c receives a vertical force, the vertical displacement of the held portion 64 f is restricted to a certain extent by the holding opening 68.

また、位置規制部66は、前記第3の実施の形態と同様に、側方規制部66bのみを備え、下方規制部66aを備えていない。   Further, as in the third embodiment, the position restricting portion 66 includes only the side restricting portion 66b and does not include the lower restricting portion 66a.

なお、図12においては、前記第1の実施の形態において説明した図4と同様に、端子61の下面側が上方を向いて示され、被覆保持部62a及び芯線保持部62bの形状は、既に曲げ加工が施され、電線91及び導電芯線に圧着された状態の形状である。   In FIG. 12, as in FIG. 4 described in the first embodiment, the lower surface side of the terminal 61 is shown facing upward, and the shapes of the covering holding portion 62a and the core wire holding portion 62b are already bent. It is a shape in a state where it is processed and crimped to the electric wire 91 and the conductive core wire.

このように、本実施の形態においては、クランク部64eよりも簡素な形状を備える鉤部64gによって被保持部64fが反転部64cの先端に接続されているので、接触腕部64の加工を簡略化することができる。したがって、端子61の加工が容易となり、生産性が向上する。また、被保持部64fの変位は、前後左右方向のみならず、上下方向にも保持用開口部68によって規制されるので、反転部64cは、いずれの方向の力を受けても、大きく変位することはない。   Thus, in the present embodiment, since the held portion 64f is connected to the tip of the reversing portion 64c by the flange portion 64g having a simpler shape than the crank portion 64e, the processing of the contact arm portion 64 is simplified. Can be Therefore, processing of the terminal 61 becomes easy and productivity is improved. Further, since the displacement of the held portion 64f is restricted by the holding opening 68 not only in the front-rear and left-right directions but also in the up-down direction, the reversing portion 64c is greatly displaced regardless of the force in any direction. There is nothing.
