Description

本発明は、カードエッジコネクタの構成部材であるコネクタ端子、詳しくはカードエッジコネクタのハウジングに開設された端子収容室に挿入することによってカードエッジコネクタを形成する部材であるコネクタ端子に関する。   The present invention relates to a connector terminal that is a component of a card edge connector, and more particularly to a connector terminal that is a member that forms a card edge connector by being inserted into a terminal accommodating chamber established in a housing of the card edge connector.

カードエッジコネクタの構成部材であるコネクタ端子として、例えば、図１２に示すようなコネクタ端子５００がある。コネクタ端子５００は、カードエッジコネクタのハウジングに開設された端子収容室（図示せず）に挿入される導電性の鞘状部５０１と、鞘状部５０１に開設された開口部５０２と、開口部５０２から通電接触部５０３を突出させた状態で鞘状部５０１内に設けられた弾性接触片５０４と、ケーブル（図示せず）を圧着固定するための結束部５０５と、を備えている。   As a connector terminal which is a constituent member of the card edge connector, for example, there is a connector terminal 500 as shown in FIG. The connector terminal 500 includes a conductive sheath-like portion 501 inserted into a terminal accommodating chamber (not shown) established in the housing of the card edge connector, an opening portion 502 established in the sheath-like portion 501, and an opening portion. An elastic contact piece 504 provided in the sheath-like portion 501 with the energization contact portion 503 protruding from 502, and a binding portion 505 for fixing a cable (not shown) by pressure bonding are provided.

コネクタ端子５００は、弾性接触片５０４の通電接触部５０３付近が開口部５０２より外に突出した形状であるため、コネクタ端子５００に対するケーブル圧着作業、ワイヤハーネス作業あるいはコネクタハウジングへの挿入作業の過程において、他の部材や作業用機材などと接触したとき、弾性接触片５０４が損傷したり、変形したり、通電接触部５０３が汚損されたりすることがある。   Since the connector terminal 500 has a shape in which the vicinity of the energizing contact portion 503 of the elastic contact piece 504 protrudes outside the opening portion 502, in the process of cable crimping work, wire harness work or connector housing work on the connector terminal 500. When contacted with other members or work equipment, the elastic contact piece 504 may be damaged or deformed, or the energizing contact portion 503 may be soiled.

そこで、このような問題を回避するため、コネクタハウジングに挿入するまでは電気接触用バネ片を端子内に収納して傷付きなどから保護する機能を有する「コネクタ」が提案されている（例えば、特許文献１参照。）。   Therefore, in order to avoid such a problem, a “connector” having a function of protecting the spring piece for electrical contact in the terminal and protecting it from being damaged until it is inserted into the connector housing has been proposed (for example, (See Patent Document 1).

実開平５−６２９７２号公報Japanese Utility Model Publication No. 5-62972

前述したように、特許文献１記載の「コネクタ」の場合、コネクタハウジングに挿入するまでは電気接触用ばね片が囲み壁内に収納された状態に保たれるため、傷付き防止機能は優れている。しかし、ばね片がばね片押動突条に乗り上げることで、ばね片の電気接触部を囲み壁から突出させているため、ばね片の公差やばね片の変形、囲み壁の公差などが累積することにより、ばね片の突出量が変化するため、接触信頼性が損なわれる可能性がある。   As described above, in the case of the “connector” described in Patent Document 1, since the spring piece for electrical contact is kept in the surrounding wall until it is inserted into the connector housing, the scratch prevention function is excellent. Yes. However, since the spring piece runs on the spring piece pushing ridge, the electrical contact portion of the spring piece protrudes from the surrounding wall, so the tolerance of the spring piece, deformation of the spring piece, tolerance of the surrounding wall, etc. accumulate. As a result, the amount of protrusion of the spring piece changes, which may impair contact reliability.

そこで本発明は、コネクタハウジングに挿着するまでの過程で、通電用の弾性接触片が損傷したり、変形したりすることを防止することができ、接触信頼性に優れたコネクタ端子を提供することを目的とする。   Therefore, the present invention provides a connector terminal that can prevent the elastic contact piece for energization from being damaged or deformed until it is inserted into the connector housing, and has excellent contact reliability. For the purpose.

本発明のコネクタ端子は、コネクタハウジングに形成された端子収容室に挿入される鞘状部と、前記鞘状部に一端部が固定され、他端部が、前記鞘状部の挿入方向と反対側に向けて折り曲げられ、他端部の先端を自由端とした弾性接触片と、を備え、前記鞘状部に、前記弾性接触片の通電接触部を突出させる突出用開口と、前記突出用開口から前記通電接触部が突出した状態で、前記弾性接触片の他端部を係止する端子突起部と、が形成され、
前記端子収容室へ前記鞘状部を挿入することで、前記弾性接触片の他端部が、前記端子収容室内に設けられたハウジング突起部に接触して、進行が阻止されて弾性変形し、前記弾性接触片の他端部の屈曲の開度が大きくなって起立して、前記通電接触部が前記突出用開口から突出すると共に、前記弾性接触片の他端部が、前記端子突起部に乗り上げて、越えることで、前記弾性接触片の復帰力により前記弾性接触片の他端部が前記端子突起部を押圧した状態となり、前記弾性接触片の他端部を前記端子突起部に係止させることを特徴とする。
The connector terminal of the present invention has a sheath-like portion inserted into a terminal accommodating chamber formed in the connector housing, one end portion fixed to the sheath-like portion, and the other end opposite to the insertion direction of the sheath-like portion. An elastic contact piece that is bent toward the side and has a distal end at the other end as a free end, and a protrusion opening for projecting an energizing contact portion of the elastic contact piece on the sheath-like portion, and the protrusion In a state where the energization contact portion protrudes from the opening, a terminal projection portion that locks the other end portion of the elastic contact piece is formed,
By inserting the sheath-like portion into the terminal accommodating chamber, the other end portion of the elastic contact piece comes into contact with a housing protrusion provided in the terminal accommodating chamber, and the progress is prevented and elastically deformed, The opening degree of bending of the other end portion of the elastic contact piece rises and rises so that the energizing contact portion protrudes from the protrusion opening, and the other end portion of the elastic contact piece extends to the terminal protrusion portion. By climbing and overcoming, the other end of the elastic contact piece presses the terminal protrusion by the restoring force of the elastic contact piece, and the other end of the elastic contact piece is locked to the terminal protrusion. It is characterized by making it.

本発明によれば、端子収容室に鞘状部を挿入する前では、弾性接触片の通電接触部は突出用開口から突出していない状態である。従って、弾性接触片を保護することができる。鞘状部が端子収容室に挿入されると、弾性接触片の他端部が端子収容室内に設けられたハウジング突起部に接触することで、弾性接触片が弾性変形して通電接触部を突出用開口から突出させることができる。そして、端子突起部に乗り上げ、越えることで、弾性接触片の他端部を端子突起部に係止させることができるので、通電接触部の突出量はコネクタハウジングに依存せず、弾性接触片のみの要因に依存するので、通電接触部の突出量を安定させることができる。
According to the present invention, before the sheath portion is inserted into the terminal accommodating chamber, the energization contact portion of the elastic contact piece is not protruding from the protruding opening. Therefore, the elastic contact piece can be protected. When the sheath-like portion is inserted into the terminal receiving chamber, the other end portion of the elastic contact piece comes into contact with the housing protrusion provided in the terminal receiving chamber, so that the elastic contact piece is elastically deformed to protrude the energizing contact portion. It can protrude from the opening for use. Since the other end of the elastic contact piece can be locked to the terminal protrusion by riding on and over the terminal protrusion, the protruding amount of the energizing contact portion does not depend on the connector housing, but only the elastic contact piece. Therefore, the protruding amount of the energizing contact portion can be stabilized.

前記弾性接触片が、前記鞘状部の挿入方向の前縁部分に形成されたＵ字状の折り曲げ部を介して前記鞘状部に連設されているのが望ましい。
このような構成とすれば、鞘状部と弾性接触片とを連続した材料で一体的に形成することができるので、生産性の向上を図ることができ、コネクタハウジングの端子収容室に挿着された後の弾性接触片は安定した弾性を発揮することができる。 It is desirable that the elastic contact piece is connected to the sheath portion via a U-shaped bent portion formed at a front edge portion in the insertion direction of the sheath portion.
With such a configuration, the sheath-like portion and the elastic contact piece can be integrally formed of a continuous material, so that productivity can be improved and the sheath can be inserted into the terminal housing chamber of the connector housing. Then, the elastic contact piece can exhibit stable elasticity.

前記鞘状部と前記弾性接触片とに、前記ハウジング突起部を、前記弾性接触片の他端部まで案内するスリット部が形成されているのが望ましい。
鞘状部と弾性接触片とに、スリット部が形成されていると、ハウジング突起部を確実に、弾性接触片の他端部まで案内させることができる。 It is desirable that a slit for guiding the housing protrusion to the other end of the elastic contact piece is formed in the sheath-like portion and the elastic contact piece.
If the slit part is formed in the sheath-like part and the elastic contact piece, the housing protrusion can be reliably guided to the other end of the elastic contact piece.

前記端子突起部が、前記スリット部を挟んで２ヵ所に形成されていると、弾性接触片の他端部を平均的に係止させることができる。   If the terminal protrusions are formed at two locations across the slit, the other end of the elastic contact piece can be locked on average.

前記弾性接触片の他端部に湾曲部が形成されているのが望ましい。通電接触部が突出して他の端子に接触するときに、接触荷重が高すぎる場合に、弾性接触片の他端部に湾曲部が形成されていると湾曲部が弾性変形することで接触荷重を緩和させることができる。   It is desirable that a curved portion is formed at the other end of the elastic contact piece. If the contact load is too high when the current-carrying contact part protrudes and contacts another terminal, if the curved part is formed at the other end of the elastic contact piece, the curved part is elastically deformed to reduce the contact load. Can be relaxed.

本発明により、コネクタハウジングに挿着するまでの過程で、通電用の弾性接触片が損傷したり、変形したりするのを防止することができ、通電接触部の突出量を安定させることができるので、接触信頼性に優れたコネクタ端子を提供することができる。   According to the present invention, it is possible to prevent the elastic contact piece for energization from being damaged or deformed until it is inserted into the connector housing, and to stabilize the protruding amount of the energization contact portion. Therefore, a connector terminal with excellent contact reliability can be provided.

図１〜図６に示すように、本発明の実施の形態に係るコネクタ端子１０は、カードエッジコネクタ１００のコネクタハウジング１０１に形成された端子収容室１０２に挿入される導電性の鞘状部２０と、鞘状部２０と導通した状態で鞘状部２０内に設けられた弾性接触片３０と、鞘状部２０の後方に形成され、ケーブルＣを圧着固定するための結束部４０と、結束部４０の後方に配設され、ケーブルＣが挿通される防水栓５０と、を備えている。
コネクタ端子１０を構成する鞘状部２０、弾性接触片３０および結束部４０などは導電性の良好な金属板を曲げ加工することにより、一体的に形成されている。 As shown in FIGS. 1 to 6, the connector terminal 10 according to the embodiment of the present invention includes a conductive sheath-like portion 20 that is inserted into a terminal accommodating chamber 102 formed in the connector housing 101 of the card edge connector 100. An elastic contact piece 30 provided in the sheath-like portion 20 in a state of being electrically connected to the sheath-like portion 20; a binding portion 40 formed on the rear side of the sheath-like portion 20 for crimping and fixing the cable C; And a waterproof plug 50 through which the cable C is inserted.
The sheath portion 20, the elastic contact piece 30, the binding portion 40, and the like constituting the connector terminal 10 are integrally formed by bending a metal plate having good conductivity.

なお、以下の説明においての「前後」という表現は、コネクタハウジング１０１の端子収容室１０２に対するコネクタ端子１０の挿入方向（図１に示す矢線Ｘ方向）を「前」とし、その反対方向を「後」として表現したものである。   In the following description, the expression “front and rear” means that the insertion direction of the connector terminal 10 with respect to the terminal accommodating chamber 102 of the connector housing 101 (direction of arrow X in FIG. 1) is “front” and the opposite direction is “ It is expressed as “after”.

鞘状部２０の横断面形状は矩形状をなし、端子が形成された回路基板Ｂが挿入される基板挿入溝１０３側である端子側面２１に、弾性接触片３０の一部が突出する突出用開口２２が形成されている。端子側面２１とは反対側となる鞘状部２０の背面２３の前縁部分には、スリット部２４が形成されている。スリット部２４は、端子収容室１０２に設けられたハウジング突起部１０４を案内するもので、コネクタ端子１０の軸線に沿って鞘状部２０の幅方向の略中央に形成されている。   The cross-sectional shape of the sheath-like portion 20 is rectangular, and a part of the elastic contact piece 30 protrudes from the terminal side surface 21 on the side of the board insertion groove 103 into which the circuit board B on which the terminal is formed is inserted. An opening 22 is formed. A slit portion 24 is formed at the front edge portion of the back surface 23 of the sheath-like portion 20 on the side opposite to the terminal side surface 21. The slit portion 24 guides the housing protruding portion 104 provided in the terminal accommodating chamber 102, and is formed at the approximate center in the width direction of the sheath-like portion 20 along the axis of the connector terminal 10.

鞘状部２０のスリット部２４の後部両側に、鞘状部２０に凹部を形成することで、鞘状部２０内に突出した端子突起部２５が形成されている。
端子突起部２５は、挿入方向の前側を、弾性接触片３０が乗り上げる傾斜面２５ａとし、後側が、弾性接触片３０の端面３３ａを係止させるため、背面２３とのなす角度が傾斜面２５ａより大きい係止面２５ｂとすることにより、側面視形状が略直角三角形状に形成され、背面２３側から見た形状が略二等辺三角形状に形成されている。 By forming recesses in the sheath-like part 20 on both sides of the rear part of the slit part 24 of the sheath-like part 20, terminal protrusions 25 protruding into the sheath-like part 20 are formed.
The terminal projection 25 has an inclined surface 25a on which the elastic contact piece 30 rides on the front side in the insertion direction, and the rear side locks the end surface 33a of the elastic contact piece 30. Therefore, the angle formed with the back surface 23 is larger than the inclined surface 25a. By using the large locking surface 25b, the side view shape is formed in a substantially right triangle shape, and the shape viewed from the back surface 23 side is formed in a substantially isosceles triangle shape.

弾性接触片３０は、鞘状部２０の背面２３の前縁部分に形成されたＵ字状の折り曲げ部２６を介して鞘状部２０から連設されていることで、弾性接触片３０の一端部が鞘状部２０に固定されている。この弾性接触片３０の一端部３１には、ハウジング突起部１０４が案内されるスリット部３２がコネクタ端子１０の軸線に沿って形成されている。この弾性接触片３０のスリット部３２は、鞘状部２０のスリット部２４と１本の直線状に並ぶ位置に形成されている。   The elastic contact piece 30 is continuously provided from the sheath-like part 20 via a U-shaped bent part 26 formed at the front edge portion of the back surface 23 of the sheath-like part 20, so that one end of the elastic contact piece 30 is provided. The part is fixed to the sheath-like part 20. A slit 32 for guiding the housing protrusion 104 is formed at one end 31 of the elastic contact piece 30 along the axis of the connector terminal 10. The slit portion 32 of the elastic contact piece 30 is formed at a position aligned with the slit portion 24 of the sheath-like portion 20 in a straight line.

弾性接触片３０は、後方部分を側面視形状がＵ字状をなすように、鞘状部２０の挿入方向と反対側に向けて折り曲げ、その先端（他端部３３）を自由端としている。他端部３３先端には端面３３ａが形成され、端面３３ａの中央部分には凹部３３ｂが形成されている。弾性接触片３０の他端部３３の端面３３ａが端子突起部２５に係止されると、鞘状部２０の背面２３に接触した状態に保たれ、弾性接触片３０が突出用開口２２に向かって付勢させられた状態となる。弾性接触片３０の屈曲部分は、突出用開口２２から突出して回路基板Ｂの端子に接触する通電接触部３４である。   The elastic contact piece 30 is bent toward the side opposite to the insertion direction of the sheath-like portion 20 so that the rear portion has a U-shape when viewed from the side, and the tip (the other end portion 33) is a free end. An end face 33a is formed at the tip of the other end 33, and a recess 33b is formed at the center of the end face 33a. When the end surface 33 a of the other end portion 33 of the elastic contact piece 30 is locked to the terminal protrusion 25, the elastic contact piece 30 is kept in contact with the back surface 23 of the sheath-like portion 20, and the elastic contact piece 30 faces the protruding opening 22. And become energized. A bent portion of the elastic contact piece 30 is an energization contact portion 34 that protrudes from the protrusion opening 22 and contacts a terminal of the circuit board B.

結束部４０は、ケーブルＣの外部絶縁体の外周を保持する外被かしめ部４１と、外部絶縁体に被覆された電線を保持して鞘状部２０と導通接続する導体かしめ部４２とにより形成されている。
防水栓５０は、コネクタ端子１０が端子収容室１０２に挿入されると、端子収容室１０２の後端に蓋となって圧入される。防水栓５０は、端子収容室１０２の後端に配設されることで、端子収容室１０２とケーブルＣとの隙間を塞ぎ、水密性を確保することができる。 The bundling portion 40 is formed by an outer caulking portion 41 that holds the outer periphery of the external insulator of the cable C, and a conductor caulking portion 42 that holds an electric wire covered with the outer insulator and is electrically connected to the sheath-like portion 20. Has been.
When the connector terminal 10 is inserted into the terminal accommodating chamber 102, the waterproof plug 50 is press-fitted into the rear end of the terminal accommodating chamber 102 as a lid. The waterproof plug 50 is disposed at the rear end of the terminal accommodating chamber 102, thereby closing the gap between the terminal accommodating chamber 102 and the cable C and ensuring water tightness.

以上のように構成された本発明の実施の形態に係るコネクタ端子の使用状態を図面に基づいて説明する。
図１に示すように、ケーブルＣが結束部４０に圧着固定されたコネクタ端子１０の鞘状部２０を、折り曲げ部２６を前方に向け、コネクタハウジング１０１の背面側から端子収容室１０２に向かって矢線Ｘ方向に挿入する。 The usage state of the connector terminal according to the embodiment of the present invention configured as described above will be described with reference to the drawings.
As shown in FIG. 1, the sheath-like portion 20 of the connector terminal 10 in which the cable C is fixed to the bundling portion 40 is directed toward the terminal accommodating chamber 102 from the back side of the connector housing 101 with the bent portion 26 facing forward. Insert in the direction of arrow X.

図５に示すように、コネクタ端子１０の挿入が進み、コネクタ端子１０の先端がハウジング突起部１０４の位置まで到達すると、弾性接触片３０のスリット部３２と、鞘状部２０のスリット部２４とが、ハウジング突起部１０４を案内しながら、ハウジング突起部１０４を鞘状部２０の奥側へ位置させる。   As shown in FIG. 5, when the insertion of the connector terminal 10 proceeds and the tip of the connector terminal 10 reaches the position of the housing protrusion 104, the slit portion 32 of the elastic contact piece 30 and the slit portion 24 of the sheath-like portion 20 However, the housing protruding portion 104 is positioned on the back side of the sheath-shaped portion 20 while guiding the housing protruding portion 104.

コネクタ端子１０の挿入が進むと、スリット部２４，３２内をハウジング突起部１０４がスライドしながらコネクタ端子１０が進み、ハウジング突起部１０４が弾性接触片３０の他端部３３の凹部３３ｂに当接する。ハウジング突起部１０４が弾性接触片３０の他端部３３の凹部３３ｂに当接した時点では、弾性接触片３０は原形に保たれており、その高さＨ１は鞘状部２０の高さより低い状態にある。
鞘状部２０と弾性接触片３０とに、スリット部２４，３２が形成されているので、ハウジング突起部１０４を確実に弾性接触片３０の他端部３３まで案内させることができる。 When the insertion of the connector terminal 10 proceeds, the connector terminal 10 advances while the housing protrusion 104 slides in the slit portions 24 and 32, and the housing protrusion 104 contacts the recess 33 b of the other end portion 33 of the elastic contact piece 30. . At the time when the housing protrusion 104 comes into contact with the recess 33b of the other end portion 33 of the elastic contact piece 30, the elastic contact piece 30 is kept in its original shape, and its height H1 is lower than the height of the sheath-like portion 20. It is in.
Since the slit portions 24 and 32 are formed in the sheath portion 20 and the elastic contact piece 30, the housing protrusion 104 can be reliably guided to the other end portion 33 of the elastic contact piece 30.

更に、コネクタ端子１０の挿入が進むと、図６に示すように、弾性接触片３０の他端部３３がハウジング突起部１０４により挿入方向への移動が阻止される。弾性接触片３０の他端部３３はハウジング突起部１０４により進行が阻止されているが、鞘状部２０は挿入方向へ進行しているので、これに伴って弾性接触片３０が弾性変形して、その屈曲の開度が大きくなり、起立していくので、通電接触部３４が突出用開口２２より突出し、その高さＨ２は鞘状部２０より高くなる。   Further, when the insertion of the connector terminal 10 proceeds, the other end portion 33 of the elastic contact piece 30 is prevented from moving in the insertion direction by the housing protrusion 104 as shown in FIG. The other end portion 33 of the elastic contact piece 30 is prevented from advancing by the housing projection 104, but the sheath-like portion 20 is advanced in the insertion direction, and accordingly, the elastic contact piece 30 is elastically deformed. Since the opening degree of the bending increases and rises, the energizing contact portion 34 protrudes from the protruding opening 22, and the height H <b> 2 is higher than the sheath-shaped portion 20.

このとき、鞘状部２０の端子突起部２５の位置まで弾性接触片３０の他端部３３が開くと、他端部３３は端子突起部２５の傾斜面２５ａ（図８参照）に乗り上げる。更に、傾斜面２５ａに沿って摺動しながら、弾性接触片３０の他端部３３が開き、他端部３３の端面３３ａが傾斜面２５ａを越えると、図９に示すように、弾性接触片３０の復帰力により他端部３３が係止面２５ｂを押圧した状態となり、他端部３３の端面３３ａが係止面２５ｂに係止された状態となる。
At this time, when the other end portion 33 of the elastic contact piece 30 is opened to the position of the terminal projection portion 25 of the sheath-like portion 20, the other end portion 33 rides on the inclined surface 25a (see FIG. 8) of the terminal projection portion 25. Further, while sliding along the inclined surface 25a, opens the other end portion 33 of the resilient contact piece 30, the end face 33a of the other end portion 33 Eru Yue an inclined surface 25a, as shown in FIG. 9, the elastic contact The other end 33 presses the locking surface 25b by the restoring force of the piece 30, and the end surface 33a of the other end 33 is locked to the locking surface 25b.

弾性接触片３０の他端部３３が端子突起部２５に係止された状態となることで、弾性接触片３０の通電接触部３４を突出用開口２２から突出させた状態に保つことができる。また、図７に示すように、通電接触部３４の突出量を、カードエッジ型の回路基板Ｂを基板挿入溝１０３に挿入して、回路基板Ｂの回路端子部と電気的接続を得るのに十分な高さとすることができる。   Since the other end portion 33 of the elastic contact piece 30 is engaged with the terminal protrusion 25, the energization contact portion 34 of the elastic contact piece 30 can be kept protruding from the protruding opening 22. Further, as shown in FIG. 7, the protruding amount of the energization contact portion 34 is used to obtain the electrical connection with the circuit terminal portion of the circuit board B by inserting the card edge type circuit board B into the board insertion groove 103. It can be set to a sufficient height.

この通電接触部３４の突出量は、弾性接触片３０の開き度合いや、弾性接触片３０の公差と鞘状部２０の端子突起部２５の形成位置の誤差など、コネクタ端子１０のみに依存し、コネクタハウジング１０１の公差には依存しない。従って、通電接触部３４の突出量がコネクタ端子１０とコネクタハウジング１０１との累積公差による影響を受けないため、通電接触部３４の突出量を安定させることができる。よって、接触信頼性に優れたコネクタ端子１０とすることができる。   The amount of protrusion of the energizing contact portion 34 depends only on the connector terminal 10, such as the degree of opening of the elastic contact piece 30, the tolerance of the elastic contact piece 30 and the formation position error of the terminal protrusion 25 of the sheath-like portion 20, It does not depend on the tolerance of the connector housing 101. Therefore, since the protruding amount of the energizing contact portion 34 is not affected by the accumulated tolerance between the connector terminal 10 and the connector housing 101, the protruding amount of the energizing contact portion 34 can be stabilized. Therefore, the connector terminal 10 having excellent contact reliability can be obtained.

本実施の形態では、鞘状部２０と弾性接触片３０とを連続した材料で一体的に形成しているので、生産性の向上を図ることができ、コネクタハウジング１０１の端子収容室１０２に挿着された後の弾性接触片３０は安定した弾性を発揮することができる。   In the present embodiment, since the sheath-like portion 20 and the elastic contact piece 30 are integrally formed of a continuous material, productivity can be improved, and insertion into the terminal accommodating chamber 102 of the connector housing 101 is possible. The elastic contact piece 30 after being worn can exhibit stable elasticity.

また、本実施の形態では、端子突起部２５が、スリット部２４を挟んで２ヵ所に形成されているので、弾性接触片３０の他端部３３の端面３３ａを偏りなく平均的に係止させることができる。従って、弾性接触片３０の通電接触部３４の回路基板Ｂの回路端子部への接触を安定しておこなうことができる。   Further, in the present embodiment, since the terminal protrusion 25 is formed at two positions across the slit 24, the end surface 33a of the other end 33 of the elastic contact piece 30 is locked evenly on average. be able to. Therefore, the contact of the energization contact portion 34 of the elastic contact piece 30 to the circuit terminal portion of the circuit board B can be stably performed.

次に、本発明の実施の形態に係るコネクタ端子の変形例を図面に基づいて説明する。なお、図１１においては、図９と同じ構成のものは同符号を付して説明を省略する。
変形例では、弾性接触片の他端部に湾曲部が形成されていることを特徴とするものである。 Next, a modification of the connector terminal according to the embodiment of the present invention will be described with reference to the drawings. In FIG. 11, the same components as those in FIG.
In the modification, a curved portion is formed at the other end of the elastic contact piece.

図１１に示すように、弾性接触片３０ｘの他端部３３に、湾曲部３５が形成されている。湾曲部３５は、弾性接触片３０ｘの内側に凸のＵ字状に形成されている。
例えば、図７に示す弾性接触片３０に回路基板Ｂの回路端子部を接触させようとしたときに、弾性接触片３０が弾性変形しにくく、弾性接触片３０の接触荷重が高すぎる場合がある。 As shown in FIG. 11, a curved portion 35 is formed at the other end portion 33 of the elastic contact piece 30x. The curved portion 35 is formed in a convex U shape inside the elastic contact piece 30x.
For example, when the circuit terminal portion of the circuit board B is brought into contact with the elastic contact piece 30 shown in FIG. 7, the elastic contact piece 30 is not easily elastically deformed, and the contact load of the elastic contact piece 30 may be too high. .

そのようなときに、弾性接触片３０ｘの他端部３３に湾曲部３５を形成することで、通電接触部３４を回路基板Ｂの回路端子部に接触させると、弾性度の低い湾曲部３５が弾性変形するため、通電接触部３４の突出用開口２２からの突出量を変えずに、弾性接触片３０ｘの接触荷重を緩和させることができる。   In such a case, if the energizing contact portion 34 is brought into contact with the circuit terminal portion of the circuit board B by forming the bending portion 35 at the other end portion 33 of the elastic contact piece 30x, the bending portion 35 having low elasticity is formed. Since the elastic deformation occurs, the contact load of the elastic contact piece 30x can be reduced without changing the amount of protrusion of the energizing contact portion 34 from the protrusion opening 22.

なお、この変形例では、湾曲部３５をＵ字状としているが、Ｖ字状としたり、Ｗ字状としたり、連続した波形としたりすることができる。   In this modification, the curved portion 35 is U-shaped, but can be V-shaped, W-shaped, or a continuous waveform.

以上、本発明の実施の形態では、弾性接触片３０の一端部３１を挿入側に位置させ、固定し、他端部３３を反対側に位置させ、自由端として、鞘状部２０に形成された端子突起部２５に係止させていた。しかし、弾性接触片の他端部を挿入側に位置させ、自由端とし、一端部を反対側に位置させ、固定して、ハウジング突起部１０４により他端部の移動を阻止することで、他端部を一端部側に移動させて、端子突起部２５に係止させるようにしてもよい。   As described above, in the embodiment of the present invention, one end portion 31 of the elastic contact piece 30 is positioned and fixed on the insertion side, the other end portion 33 is positioned on the opposite side, and the sheath-shaped portion 20 is formed as a free end. The terminal protrusion 25 was locked. However, the other end of the elastic contact piece is positioned on the insertion side, the free end, the one end is positioned on the opposite side, fixed, and the other end is prevented from moving by the housing projection 104. The end portion may be moved to the one end portion side and locked to the terminal protrusion 25.

本発明のコネクタ端子は、各種電気・電子機器用の電気コネクタあるいは車載用の電気コネクタの構成部材として、電気・電子産業や自動車産業などの分野において広く利用することができる。   The connector terminal of the present invention can be widely used in the fields of the electric / electronic industry, the automobile industry, etc. as a component of various electrical / electronic equipment electrical connectors or in-vehicle electrical connectors.
