Description

本発明は、側壁の側縁側同士を折り重ねることによって略筒状に形成された端子挿入空間を有する端子、特に、該端子挿入空間に相手端子と接触させる接触片を有する端子に関する。   The present invention relates to a terminal having a terminal insertion space formed in a substantially cylindrical shape by folding side edge sides of a side wall, and more particularly to a terminal having a contact piece in contact with a mating terminal in the terminal insertion space.

特許文献１に、この種の端子の一例が開示されている。この端子は、前端側に相手側の雄型端子が挿入される端子挿入口を有する矩形筒状の端子挿入空間を備え、該端子挿入空間は、更に、端子挿入空間を構成する一方の面から前端側に突出すると共に対向する筒壁に向けて屈曲し、互いに重ね合わされた一対の弾性接触片を備える。

特開２０１１−１５４９４４号JP 2011-154944 A

特許文献１の構成によれば、第２弾性接触片を利用して、第１弾性接触片のバネ力を補強することができるが、ここでは、第１弾性接触片に設けた相手端子と接触する接点部が、第１弾性接触片を支持している支持部よりも、雄型端子の挿入方向において手前側に位置付けられているため、相手端子の挿入の初期段階において、相手端子が接点部と比較的大きな力を受ける状態で衝突することになってしまうため、この衝突によって相手端子の挿入が妨げられてしまうおそれがある。特に、第１弾性接触片を補強する第２弾性接触片を設けている場合には、接点部のバネ力が強化されていることから、この問題はより大きなものとなる。
本願発明はこのような従来技術における問題点を解決するためになされたものであり、補強部によって相手端子と接触する接点部におけるバネ力が強化されている場合においても、相手端子の挿入を円滑にすることができる端子、該端子を用いたケーブル側コネクタ、及び、該ケーブル側コネクタを用いたケーブルコネクタ装置を提供することを目的とする。 According to the configuration of Patent Document 1, it is possible to reinforce the spring force of the first elastic contact piece using the second elastic contact piece. Here, the contact with the mating terminal provided on the first elastic contact piece is possible. Since the contact portion to be positioned is positioned closer to the front side in the insertion direction of the male terminal than the support portion supporting the first elastic contact piece, the counterpart terminal is connected to the contact portion in the initial stage of insertion of the counterpart terminal. Therefore, there is a possibility that insertion of the mating terminal may be hindered by this collision. In particular, when the second elastic contact piece that reinforces the first elastic contact piece is provided, this problem becomes more serious because the spring force of the contact portion is strengthened.
The present invention has been made to solve such problems in the prior art, and even when the spring force at the contact portion contacting the mating terminal is reinforced by the reinforcing portion, the mating terminal can be smoothly inserted. It is an object of the present invention to provide a terminal that can be used, a cable-side connector using the terminal, and a cable connector device using the cable-side connector.

上記の課題を解決するため、本発明の一態様による端子は、手前から奥に向かって相手端子が挿入される端子挿入空間を有する端子であって、前記端子挿入空間は、幅方向にて互いに離間され且つ高さ方向にてそれぞれ高さを有する第一及び第二の側壁の側縁側同士を折り重ねることによって略筒状に形成されており、前記端子挿入空間に近い側に配置された、前記折り重ねられた前記第一の側壁の側縁側には、前記高さ方向にて弾性変位可能な状態で片持ち梁状に支持された接触片が前記相手端子の挿入方向に沿って設けられており、前記端子挿入空間から遠い側に配置された、前記折り重ねられた前記第二の側壁の側縁側には、前記接触片を前記高さ方向にて補強する片持ち梁状に支持された補強部が前記相手端子の挿入方向に沿って設けられており、前記接触片に設けた前記相手端子との接点部は、前記接触片の支持部よりも、前記挿入方向において奥側に位置することを特徴として有する。
この態様の端子によれば、相手端子を端子挿入空間にある程度挿入した後にのみ当該相手端子を接触片と接触させることができるため、相手端子の挿入を円滑にすることができる。本構成では、特に、接触片のバネ力が補強部によって強化され、相手端子を挿入するために要する力が通常よりも大きいことから、より大きな効果を得ることができる。 In order to solve the above problems, a terminal according to an aspect of the present invention is a terminal having a terminal insertion space into which a mating terminal is inserted from the front toward the back, and the terminal insertion spaces are mutually in the width direction. It is formed in a substantially cylindrical shape by folding the side edges of the first and second side walls that are spaced apart and have a height in the height direction, and is disposed on the side close to the terminal insertion space, On the side edge side of the folded first side wall, a contact piece supported in a cantilever shape while being elastically displaceable in the height direction is provided along the insertion direction of the mating terminal. The side wall of the folded second side wall disposed on the side far from the terminal insertion space is supported in a cantilever shape that reinforces the contact piece in the height direction. Reinforced part is installed along the insertion direction of the mating terminal It is and the contact portion between the mating terminals provided in the contact piece, than the support portion of the contact piece, has a feature in that located on the rear side in the insertion direction.
According to the terminal of this aspect, since the mating terminal can be brought into contact with the contact piece only after the mating terminal is inserted into the terminal insertion space to some extent, the mating terminal can be inserted smoothly. In this configuration, in particular, since the spring force of the contact piece is strengthened by the reinforcing portion and the force required to insert the mating terminal is larger than usual, a greater effect can be obtained.

上記態様の端子において、前記高さ方向において前記接触片と対面している前記端子挿入空間の内壁に対して、前記接触片の接点部は、前記接触片の支持部よりも、前記高さ方向にて近接しているのが好ましい。
この構成によれば、相手端子は、徐々に力を受けながら、接触片の接点部と接触することになり、相手端子の挿入を円滑にすることができる。 In the terminal according to the aspect described above, the contact portion of the contact piece is higher in the height direction than the support portion of the contact piece with respect to the inner wall of the terminal insertion space facing the contact piece in the height direction. It is preferable that they are close to each other.
According to this configuration, the mating terminal comes into contact with the contact portion of the contact piece while gradually receiving force, and the mating terminal can be smoothly inserted.

上記態様の端子において、前記接触片の自由端は、前記補強部と前記高さ方向にて対面しているのが好ましい。
この構成によれば、接触片の中で最も強度が弱い自由端を、補強部によって補強することができるため、相手端子との接圧をより確実に確保するとともに、接触片の耐久性をより確実に向上させることができる。 The terminal of the said aspect WHEREIN: It is preferable that the free end of the said contact piece has faced the said reinforcement part in the said height direction.
According to this configuration, since the free end having the weakest strength among the contact pieces can be reinforced by the reinforcing portion, the contact pressure with the mating terminal can be more reliably ensured and the durability of the contact piece can be further increased. It can certainly be improved.

上記態様の端子において、前記補強部の側縁は、前記接触片とは反対側の前記補強部の面に向かって折り返されており、折り返された前記補強部の側縁に、片持ち梁状に支持されたランス用の片が形成されてもよい。
補強部の側縁側を折り返すことにより、補強部の強度を高めることができる。また、補強部の側縁側を片持ち梁状に支持することにより、補強部の側縁側をランス用の片として用いることができる。 In the terminal of the above aspect, the side edge of the reinforcing part is folded back toward the surface of the reinforcing part opposite to the contact piece, and the side edge of the folded reinforcing part is cantilevered. A lance piece supported on the lance may be formed.
The strength of the reinforcing portion can be increased by folding back the side edge side of the reinforcing portion. Further, by supporting the side edge side of the reinforcing portion in a cantilever shape, the side edge side of the reinforcing portion can be used as a lance piece.

上記態様の端子において、前記ランス用の片は、前記幅方向と前記高さ方向の双方に沿う断面において略Ｌ字形状を有するのが好ましい。
断面形状を略Ｌ字とすることにより、ランスの強度を強化することができる。 In the terminal of the above aspect, it is preferable that the lance piece has a substantially L shape in a cross section along both the width direction and the height direction.
By making the cross-sectional shape substantially L-shaped, the strength of the lance can be enhanced.

上記態様の端子において、前記接触片は、該接触片の支持部の近傍に、前記高さ方向にて前記接触片の面を打ち出した打ち出し部を有してもよい。
打ち出し部を設けることにより、打ち出しの方向及び度合いに応じて接触片の支持力を調整し、これによって接触片のバネ性を制御することができる。 In the terminal according to the aspect described above, the contact piece may include a launching part that is a surface of the contact piece that is launched in the height direction in the vicinity of the support part of the contact piece.
By providing the launching portion, the support force of the contact piece can be adjusted according to the direction and degree of launching, and thereby the spring property of the contact piece can be controlled.

上記態様の端子において、前記高さ方向にて前記接触片の接点部と対面している前記端子挿入空間の内壁に、前記高さ方向にて前記端子挿入空間側に突出する凸部を設けてもよい。
凸部を設けることにより、該凸部と接触片とによって相手端子の高さ方向における挿入距離を調整することができ、相手端子を端子挿入空間の所定位置により確実に位置決めすることができる。 In the terminal of the above aspect, a convex portion that protrudes toward the terminal insertion space in the height direction is provided on the inner wall of the terminal insertion space facing the contact portion of the contact piece in the height direction. Also good.
By providing the convex portion, the insertion distance in the height direction of the mating terminal can be adjusted by the convex portion and the contact piece, and the mating terminal can be reliably positioned at a predetermined position in the terminal insertion space.

上記態様の端子において、前記補強部は支持部によって片持ち梁状に支持されており、前記補強部の自由端側は、前記補強部の支持部よりも、前記挿入方向において奥側に位置するのが好ましい。
接触片と同様に、補強部を補強片として形成し、その自由端側を支持部よりも挿入方向において奥側に位置付けることにより、接触片の動作に同期させた状態で補強片を動作させることができ、接触片のバネ力を強化しつつ、相手端子の挿入を円滑にすることができる。 In the terminal of the above aspect, the reinforcing portion is supported in a cantilever shape by a supporting portion, and the free end side of the reinforcing portion is located on the back side in the insertion direction with respect to the supporting portion of the reinforcing portion. Is preferred.
Like the contact piece, the reinforcing part is formed as a reinforcing piece, and the reinforcing piece is operated in a state synchronized with the operation of the contact piece by positioning the free end side behind the support part in the insertion direction. Thus, the mating terminal can be inserted smoothly while strengthening the spring force of the contact piece.

また、本発明は、上記端子を保持するハウジングを有するコネクタ、該コネクタと該コネクタと嵌合される相手コネクタを特徴とする。   Further, the present invention is characterized by a connector having a housing for holding the terminal, and the connector and a mating connector fitted to the connector.

以下、添付図面を参照しつつ、本発明の好適な実施形態について説明する。尚、説明の便宜のため好適な実施形態のみを示すが、勿論、これによって本発明を限定しようとするものではない。   Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. For the convenience of explanation, only preferred embodiments are shown, but of course, the present invention is not intended to be limited thereto.

図１に、本発明の好ましい一つの実施形態による端子の斜視図を示す。ここでは、一例としてケーブル端子３０を例に挙げて説明するが、本発明をケーブル端子に限定する意図ではない。   FIG. 1 shows a perspective view of a terminal according to a preferred embodiment of the present invention. Here, the cable terminal 30 is described as an example as an example, but the present invention is not intended to be limited to the cable terminal.

ケーブル端子３０は、例えば、一枚の薄い金属板に打ち抜き、折り曲げ加工することによって形成されている。ケーブル端子３０は、本体５１と、芯線カシメ部５２、及び、外被カシメ部５３を、これらの順に有する。   The cable terminal 30 is formed, for example, by punching and bending a single thin metal plate. The cable terminal 30 includes a main body 51, a core wire crimping portion 52, and a jacket crimping portion 53 in this order.

ケーブル端子３０には、ケーブル３の芯線（図示されていない）を芯線カシメ部５２によってかしめ、且つ、ケーブル３の外被３ａを外被カシメ部５３によってかしめることにより、ケーブル３の一端を固定することができるようになっている。   One end of the cable 3 is fixed to the cable terminal 30 by caulking the core wire (not shown) of the cable 3 with the core caulking portion 52 and caulking the outer sheath 3a of the cable 3 with the outer caulking portion 53. Can be done.

図２乃至図６に、本体５１の構成を更に詳細に示す。図２は、本体５１についての図１のＡ−Ａ線断面斜視図、図３は、その前面図、図４は、その側面図、図５は、図３のＢ−Ｂ線断面図、図６は、図４（ｂ）のＣ−Ｃ線断面図である。   2 to 6 show the configuration of the main body 51 in more detail. 2 is a cross-sectional perspective view of the main body 51 taken along line AA of FIG. 1, FIG. 3 is a front view thereof, FIG. 4 is a side view thereof, and FIG. 5 is a cross-sectional view taken along line BB of FIG. 6 is a cross-sectional view taken along the line CC of FIG.

本体５１には、相手端子が挿入される端子挿入空間５１ｂが形成されている。端子挿入空間５１ｂには、端子挿入口５１ａを通じて、手前から奥に向かって図示矢印「α１」方向に沿って相手端子を挿入することができる。端子挿入空間５１ｂは、幅方向（図示矢印「β」方向）にて互いに離間され且つ高さ方向（図示矢印「γ」方向）にてそれぞれ高さを有する側壁３１、４１の側縁側同士を折り重ねることにより、略筒状に形成されている。側壁３１と側壁４１は、略直角な湾曲部を介して天壁６１において互いに連結された状態にある。側壁３１には、幅方向「β」方向に貫通した係止穴３５が、これに対応して、側壁４１には、係止突起４５が、それぞれ設けられており、係止突起４５を係止穴３５に係止させることによって、側壁３１の側縁側３２と、側壁４１の側縁部４２とを固定し、略筒状体を保持している。係止突起４５は、図示矢印「α１」方向における支持部４２ａ部分に配置されており、接触片４２Ａを支持している。   The main body 51 has a terminal insertion space 51b into which a mating terminal is inserted. A mating terminal can be inserted into the terminal insertion space 51b along the direction indicated by the arrow “α1” from the front to the back through the terminal insertion port 51a. The terminal insertion space 51b is folded between the side edges of the side walls 31, 41 that are spaced apart from each other in the width direction (arrow "β" direction in the figure) and have a height in the height direction (arrow "γ" direction in the figure). By overlapping, it is formed in a substantially cylindrical shape. The side wall 31 and the side wall 41 are in a state of being connected to each other at the top wall 61 via a substantially perpendicular curved portion. The side wall 31 is provided with a locking hole 35 penetrating in the width direction “β”. Correspondingly, a locking projection 45 is provided on the side wall 41, and the locking projection 45 is locked. By engaging with the hole 35, the side edge 32 of the side wall 31 and the side edge 42 of the side wall 41 are fixed, and the substantially cylindrical body is held. The locking protrusion 45 is disposed on the support portion 42a in the illustrated arrow “α1” direction, and supports the contact piece 42A.

側壁３１の側縁側３２よりも端子挿入空間５１ｂに近い側に配置された、折り重ねられた側壁４１の側縁部４２に、相手端子の挿入方向「α」に沿って接触片４２Ａが形成されている。接触片４２Ａは、支持部４２ａによって片持ち梁状に支持されており、高さ方向「γ」において弾性変位可能である。接触片４２Ａの自由端４２ｅ側には、端子挿入空間５１ｂに挿入された相手端子と接触し得る接点部４２ｂが形成されている。   A contact piece 42A is formed along the insertion direction “α” of the mating terminal on the side edge portion 42 of the folded side wall 41, which is disposed closer to the terminal insertion space 51b than the side edge side 32 of the side wall 31. ing. The contact piece 42A is supported in a cantilever shape by the support portion 42a, and can be elastically displaced in the height direction “γ”. On the free end 42e side of the contact piece 42A, a contact portion 42b that can come into contact with a mating terminal inserted into the terminal insertion space 51b is formed.

接点部４２ｂは、山型に折り曲げることにより、高さ方向「γ」に多少突出した状態とされている。これにより、相手端子との接触をより確実に行うことができるようになっている。
また、接点部４２ｂは、接触片４２Ａの支持部４２ａよりも、挿入方向「α」において奥側に位置付けられている。相手端子が端子挿入空間５１ｂへ挿入されたとき、相手端子と接触片４２Ａの衝突を通じて相手端子に力が加わり、円滑な挿入が妨げられてしまうおそれがあるが、接点部４２ｂを支持部４２ａよりも奥側に位置付けることにより、端子挿入空間５１ｂにおいてある程度位置決めし且つ挿入にある程度勢いを与えた状態で、相手端子を接触片４２Ａと接触させることができるため、相手端子を端子挿入空間５１ｂへ円滑に挿入することができる。 The contact part 42b is in a state of slightly protruding in the height direction “γ” by being bent into a mountain shape. Thereby, a contact with the other party terminal can be performed more reliably.
Further, the contact portion 42b is positioned on the back side in the insertion direction “α” with respect to the support portion 42a of the contact piece 42A. When the mating terminal is inserted into the terminal insertion space 51b, force may be applied to the mating terminal through the collision of the mating terminal and the contact piece 42A, and smooth insertion may be hindered. Since the mating terminal can be brought into contact with the contact piece 42A while being positioned to some extent in the terminal insertion space 51b and with some momentum in the insertion, the mating terminal can be smoothly moved into the terminal insertion space 51b. Can be inserted into.

支持部４２ａの近傍に、接触片４２Ａの面を高さ方向「γ」に打ち出した打ち出し部４２ｄを設けてもよい。打ち出し部４２ｄを設けることにより、打ち出し部４２ｄにおける打ち出しの方向及び度合いに応じて支持部４２ａによる接触片４２Ａの支持力を調整し、これによって接触片４２Ａのバネ性を制御することができる。例えば、図示のように、端子挿入空間５１ｂに向かって内方に打ち出された打ち出し部４２ｄを支持部４２ａに設けることにより、支持部４２ａによる接触片４２Ａの支持力を大きく設定してもよい。また、打ち出し部４２ｄの形状を、平面視略長方形状とすることにより、バネ性の制御が容易となっている。   In the vicinity of the support portion 42a, a launching portion 42d that launches the surface of the contact piece 42A in the height direction “γ” may be provided. By providing the launch portion 42d, the support force of the contact piece 42A by the support portion 42a can be adjusted according to the direction and degree of launch at the launch portion 42d, and thereby the spring property of the contact piece 42A can be controlled. For example, as shown in the drawing, the support portion 42a may be set to have a large support force by providing the support portion 42a with a launch portion 42d that is punched inward toward the terminal insertion space 51b. In addition, by controlling the shape of the projecting portion 42d to be a substantially rectangular shape in plan view, the spring property can be easily controlled.

接触片４２Ａは、高さ方向「γ」において、端子挿入空間５１ｂを形成している天壁６１の内壁６１ｃと対面している。この内壁６１ｃに対し、接触片４２Ａの接点部４２ｂは、支持部４２ａよりも、高さ方向「γ」において近接した状態にある。この構成によれば、相手端子は、徐々に力を受けながら、接触片４２Ａの接点部４２ｂと接触することになるため、相手端子の挿入を円滑にすることができる。
また、高さ方向「γ」において接触片４２Ａの接点部４２ｂと対面している端子挿入空間５１ｂの内壁６１ｃに、高さ方向「γ」にて端子挿入空間５１ｂ側に突出する凸部６１ｂを設けてもよい。凸部６１ｂを設けることにより、該凸部６１ｂと接触片４２Ａとによって相手端子の高さ方向「γ」における挿入距離を調整することができ、相手端子を端子挿入空間５１ｂの所定位置により確実に位置決めすることができる。凸部６１ｂは、幅方向「β」において２カ所に設けられ、挿入方向「α」において接点部４２ｂの手前から接点部４２ｂを超えた奥の位置まで設けられている。 The contact piece 42A faces the inner wall 61c of the top wall 61 forming the terminal insertion space 51b in the height direction “γ”. The contact portion 42b of the contact piece 42A is closer to the inner wall 61c in the height direction “γ” than the support portion 42a. According to this configuration, the mating terminal is brought into contact with the contact portion 42b of the contact piece 42A while gradually receiving force, so that the mating terminal can be inserted smoothly.
Further, a convex portion 61b that protrudes toward the terminal insertion space 51b in the height direction “γ” is formed on the inner wall 61c of the terminal insertion space 51b that faces the contact portion 42b of the contact piece 42A in the height direction “γ”. It may be provided. By providing the convex portion 61b, the insertion distance in the height direction “γ” of the mating terminal can be adjusted by the convex portion 61b and the contact piece 42A, and the mating terminal can be surely secured by a predetermined position in the terminal insertion space 51b. Can be positioned. The convex portions 61b are provided at two locations in the width direction “β”, and are provided from the front of the contact portion 42b to the deep position beyond the contact portion 42b in the insertion direction “α”.

側壁４１の側縁部４２よりも端子挿入空間５１ｂから遠い側に配置された、折り重ねられた側壁３１の側縁側３２は、挿入方向「α」に沿って伸びており、端子挿入空間５１ｂに向かって内方に折り曲げられている。折り曲げられた側縁側３２の一部３２Ａは、接触片４２Ａの底側に位置付けられ、接触片４２Ａを高さ方向「γ」にて補強する補強部として機能する。補強片３２Ａは、接触片４２Ａと異なり、側壁４１ではなく側壁４２の側縁側に形成されている。補強片３２Ａと接触片４２Ａとを、このように互いに離間された側壁３１、３２の側縁側にそれぞれに形成することにより、補強片３２Ａと接触片４２Ａが互いに実質的に影響を与えない態様として両者の働きを完全に分けることができる。また、補強部３２Ａを設けたことにより、接触片４２Ａのバネ力は強化され、また、接触片４２Ａの耐久性は向上する。このように接触片４２Ａのバネ力が補強部３２Ａによって強化されている場合には、端子挿入空間５１ｂへ相手端子を挿入させる際に相手端子が接触片４２Ａから受ける力は補強片３２Ａを設ける前より大きくなるが、上述したように、接触片４２Ａの接点部４２ｂは、接触片４２Ａの支持部４２ａよりも、端子挿入空間５１ｂの挿入方向「α」において奥側に位置付けられていることから、このような状況においても、相手端子の挿入を円滑に行うことができる。   The side edge side 32 of the folded side wall 31 that is disposed on the side farther from the terminal insertion space 51b than the side edge portion 42 of the side wall 41 extends along the insertion direction “α” and extends into the terminal insertion space 51b. It is bent inward. A portion 32A of the bent side edge side 32 is positioned on the bottom side of the contact piece 42A and functions as a reinforcing portion that reinforces the contact piece 42A in the height direction “γ”. Unlike the contact piece 42 </ b> A, the reinforcing piece 32 </ b> A is formed not on the side wall 41 but on the side edge side of the side wall 42. By forming the reinforcing piece 32A and the contact piece 42A on the side edge sides of the side walls 31 and 32 thus separated from each other, the reinforcing piece 32A and the contact piece 42A do not substantially affect each other. The work of both can be completely separated. Further, by providing the reinforcing portion 32A, the spring force of the contact piece 42A is strengthened, and the durability of the contact piece 42A is improved. In this way, when the spring force of the contact piece 42A is reinforced by the reinforcing portion 32A, the force received by the counterpart terminal from the contact piece 42A when the counterpart terminal is inserted into the terminal insertion space 51b is before the reinforcement piece 32A is provided. Although it is larger, as described above, the contact portion 42b of the contact piece 42A is positioned on the back side in the insertion direction “α” of the terminal insertion space 51b than the support portion 42a of the contact piece 42A. Even in such a situation, the mating terminal can be smoothly inserted.

補強部３２Ａは、接触片４２Ａと同様に、片として形成されてもよい。補強片３２Ａは、支持部３２ａによって片持ち梁状に支持され、高さ方向「γ」において弾性変位可能である。補強片３２Ａの自由端３２ｅ側は、接触片４２Ａと同様に、支持部３２ａよりも挿入方向「α」において奥側に位置付けられている。このように、補強片３２Ａを接触片４２Ａと同様の態様で支持することにより、接触片４２Ａの動作に同期させた状態で補強片３２Ａを動作させることができ、接触片４２Ａのバネ力を強化しつつ、相手端子の挿入を円滑にすることができる。   The reinforcing portion 32A may be formed as a piece, like the contact piece 42A. The reinforcing piece 32A is supported in a cantilever shape by the support portion 32a and can be elastically displaced in the height direction “γ”. The free end 32e side of the reinforcing piece 32A is positioned on the back side in the insertion direction “α” with respect to the support portion 32a, like the contact piece 42A. Thus, by supporting the reinforcing piece 32A in the same manner as the contact piece 42A, the reinforcing piece 32A can be operated in synchronization with the operation of the contact piece 42A, and the spring force of the contact piece 42A is strengthened. However, the mating terminal can be inserted smoothly.

補強片３２Ａの自由端３２ｅ側は、挿入方向「α」において、接触片４２Ａの自由端４２ｅに達する長さとするのが好ましい。この場合、接触片４２Ａの自由端４２ｅは、補強片３２Ａと高さ方向「γ」において対面することになるが、この結果、接触片４２Ａの中で最も強度が弱い自由端４２ｅを、接点部４２ｂと反対側の底面４２ｆ側から補強片３２Ａによって補強することができ、相手端子との接圧をより確実に確保するとともに、接触片の耐久性をより確実に向上させることができる。   It is preferable that the free end 32e side of the reinforcing piece 32A has a length that reaches the free end 42e of the contact piece 42A in the insertion direction “α”. In this case, the free end 42e of the contact piece 42A faces the reinforcing piece 32A in the height direction “γ”. As a result, the free end 42e having the weakest strength in the contact piece 42A is replaced with the contact portion 42A. The reinforcing piece 32A can be reinforced from the side of the bottom surface 42f opposite to 42b, and the contact pressure with the mating terminal can be ensured more reliably and the durability of the contact piece can be improved more reliably.

補強片３２Ａの側縁３３は、接触片４２Ａとは反対側の補強部３２Ａの面に向かって折り返されてもよい。このような折り返し部を設けることにより、補強片３２Ａの強度を高めることができる。   The side edge 33 of the reinforcing piece 32A may be folded back toward the surface of the reinforcing portion 32A opposite to the contact piece 42A. By providing such a folded portion, the strength of the reinforcing piece 32A can be increased.

折り返された側縁３３は、ランス用の片として使用することもできる。ランス用の片として使用する場合、折り返された側縁３３を、接触片４２Ａや補強片３２Ａ等と同様に、挿入方向「α」の手前側において支持部３３ａによって片持ち梁状に支持し、高さ方向「γ」において弾性変位可能とする。ランス片３３ｂは、幅方向「β」と高さ方向「γ」の双方に沿う断面「β−γ」形状、例えば、略Ｌ字形状としてもよい。このような形状とすることにより、ランスの強度を高めることができる。   The folded side edge 33 can also be used as a lance piece. When used as a lance piece, the folded side edge 33 is supported in the form of a cantilever by a support portion 33a on the front side in the insertion direction “α”, like the contact piece 42A and the reinforcing piece 32A. Elastic displacement is possible in the height direction “γ”. The lance piece 33b may have a cross-sectional “β-γ” shape along both the width direction “β” and the height direction “γ”, for example, a substantially L shape. By setting it as such a shape, the intensity | strength of a lance can be raised.

図７乃至図９を参照して、本発明の端子３０の動作を説明する。これらの図は、図５に対応する断面図であって、端子３０に相手端子７が挿入されたときの端子３０の動作を段階的に示した図である。尚、端子挿入空間５１ｂへの相手端子７の挿入を円滑にするため、相手端子７の先端は先細形状とされている。   The operation of the terminal 30 of the present invention will be described with reference to FIGS. These drawings are cross-sectional views corresponding to FIG. 5, and are diagrams illustrating the operation of the terminal 30 when the mating terminal 7 is inserted into the terminal 30 in a stepwise manner. In order to facilitate the insertion of the mating terminal 7 into the terminal insertion space 51b, the tip of the mating terminal 7 is tapered.

図７の（ａ）に示すように、端子挿入空間５１ｂへ相手端子７が挿入される以前において、接触片４２Ａは、曲部４２ｃにおいて補強片３２Ａと接触した状態にあるが、曲部４２ｃより自由端４２ｅ側においては、高さ方向「γ」において補強片３２Ａと多少離間され、隙間が形成された状態にある。
図７の（ｂ）に、接触片４２Ａと補強片３２Ａの衝突部付近の部分拡大図を示す。この図に示すように、接触片４２Ａの底面４２ｆと、補強片３２Ａの上面３２ｂとの間に隙間が形成されていることにより、接触片４２Ａが補強片３２Ａの側に変位した際に、接触片４２Ａが補強片３２Ａに接触（衝突）するまでの間（接触当初段階）は接触片４２Ａのみの弾性力（反力）が相手端子７に加えられる。そして、接触片４２Ａが補強片３２Ａに接触（衝突）した後は、接触片４２Ａの弾性力（反力）に加え、補強片３２Ａの弾性力（反力）も加わることとなり、結果、２つの片の弾性力（反力）が相手端子７に加わることとなる。従って、接触当初段階では少ない挿入力で相手端子７を端子３０に挿入できるとともに、挿入後は２つの片の弾性力（反力）により、接触片４２Ａと相手端子７との接触状態を確実に保持することができ、例えば、振動が加わる条件下においても相手端子７と端子３０との瞬断などの不具合を生じることがない。
また、自由端４２ｅ側に形成された隙間ｍの大きさを接点部４２ｂ側に形成された隙間ｎの大きさよりも、多少小さく設定することにより、接触片４２Ａが補強片３２Ａの側に変位した際に、自由端４２ｅ側が先に補強片３２Ａと確実に接触する、すなわち、方向「α」における接触片４２Ａと補強片３２Ａとの接触位置をほぼ同じ位置に制御することができることになり、補強片３２Ａの弾性力（反力）を制御できる。更に、これらの隙間ｍ、ｎの大きさを、接触片４２Ａや補強片３２Ａの板厚よりも小さく設定することにより、接触片４２Ａに過大な変位が生じる前に補強片３２Ａに接触させることができる。隙間ｍ、ｎの大きさや位置は、折り曲げの角度や位置を調整することで制御できる。 As shown in FIG. 7A, before the mating terminal 7 is inserted into the terminal insertion space 51b, the contact piece 42A is in contact with the reinforcing piece 32A at the bent portion 42c. On the free end 42e side, the gap is formed slightly apart from the reinforcing piece 32A in the height direction “γ”.
FIG. 7B is a partially enlarged view of the vicinity of the collision portion between the contact piece 42A and the reinforcing piece 32A. As shown in this figure, when a gap is formed between the bottom surface 42f of the contact piece 42A and the upper surface 32b of the reinforcing piece 32A, the contact piece 42A is contacted when displaced to the reinforcing piece 32A side. The elastic force (reaction force) of only the contact piece 42A is applied to the mating terminal 7 until the piece 42A contacts (collises) the reinforcing piece 32A (initial stage of contact). Then, after the contact piece 42A comes into contact (collision) with the reinforcing piece 32A, in addition to the elastic force (reaction force) of the contact piece 42A, the elastic force (reaction force) of the reinforcement piece 32A is also applied. The elastic force (reaction force) of the piece is applied to the mating terminal 7. Accordingly, at the initial stage of contact, the mating terminal 7 can be inserted into the terminal 30 with a small insertion force, and after the insertion, the contact state between the contact piece 42A and the mating terminal 7 is ensured by the elastic force (reaction force) of the two pieces. For example, there is no problem such as instantaneous disconnection between the mating terminal 7 and the terminal 30 even under a condition where vibration is applied.
Further, the contact piece 42A is displaced toward the reinforcing piece 32A by setting the size of the gap m formed on the free end 42e side to be slightly smaller than the size of the gap n formed on the contact portion 42b side. In this case, the free end 42e side is surely brought into contact with the reinforcing piece 32A first, that is, the contact position between the contact piece 42A and the reinforcing piece 32A in the direction “α” can be controlled to substantially the same position. The elastic force (reaction force) of the piece 32A can be controlled. Further, by setting the sizes of the gaps m and n to be smaller than the plate thickness of the contact piece 42A or the reinforcing piece 32A, the gap can be brought into contact with the reinforcing piece 32A before excessive displacement occurs in the contact piece 42A. it can. The size and position of the gaps m and n can be controlled by adjusting the bending angle and position.

図８に示すように、端子挿入空間５１ｂへ相手端子７が挿入される際、相手端子７は、端子挿入空間５１ｂの内壁６１ｃに設けた凸部６１ｂによって接触片４２Ａに向かって徐々にその位置を調整されつつ、接触片４２Ａ、特に、接触片４２Ａの自由端４２ｅの近傍に設けた接点部４２ｂと、凸部６１ｂとの間の隙間に挿入される。   As shown in FIG. 8, when the mating terminal 7 is inserted into the terminal insertion space 51b, the mating terminal 7 is gradually positioned toward the contact piece 42A by the convex portion 61b provided on the inner wall 61c of the terminal insertion space 51b. The contact piece 42A, in particular, the contact portion 42b provided in the vicinity of the free end 42e of the contact piece 42A, and the convex portion 61b are inserted.

相手端子７が端子挿入空間５１ｂへ更に挿入され、相手端子７が接触片４２Ａと接触すると、図９に示すように、接触片４２Ａの自由端４２ｅ側は、補強片３２Ａとの接触点である曲部４２ｃを支点として、補強片３２Ａの側に向かって変位する。この結果、接触片４２Ａは、自由端４２ｅ側の底面４２ｆにおいて、補強片３２Ａの上面３２ｂと衝突し、補強片３２Ａによって自由端４２ｅ側を支持される。補強片３２Ａは、接触片４２Ａと同様に、弾性変位可能に設けられているため、接触片４２Ａが補強片３２Ａに衝突した後は接触片４２Ａと同期して変位し、これによって、接触片４２Ａにバネ力（反力）を与えつつ、相手端子７の円滑な挿入を可能とする。   When the mating terminal 7 is further inserted into the terminal insertion space 51b and the mating terminal 7 comes into contact with the contact piece 42A, as shown in FIG. 9, the free end 42e side of the contact piece 42A is a contact point with the reinforcing piece 32A. The bending portion 42c is used as a fulcrum to displace toward the reinforcing piece 32A. As a result, the contact piece 42A collides with the upper surface 32b of the reinforcing piece 32A on the bottom surface 42f on the free end 42e side, and the free end 42e side is supported by the reinforcing piece 32A. Since the reinforcing piece 32A is provided so as to be elastically displaceable like the contact piece 42A, after the contact piece 42A collides with the reinforcing piece 32A, the reinforcing piece 32A is displaced in synchronization with the contact piece 42A, and thereby the contact piece 42A. The mating terminal 7 can be smoothly inserted while applying a spring force (reaction force) to.

The perspective view of the connector apparatus 1 by one preferable embodiment of this is shown, Furthermore, the centerline sectional drawing of the connector 20 is shown in FIG.

コネクタ２０の一例として、ここではケーブルコネクタを例に挙げて説明するが、本発明は、ケーブルコネクタ２０に限定されるものではない。同様に、コネクタ装置１の一例として、ここではケーブルコネクタ装置を例に挙げて説明するが、本発明は、ケーブルコネクタ装置１に限定されるものではない。   As an example of the connector 20, a cable connector will be described as an example here, but the present invention is not limited to the cable connector 20. Similarly, as an example of the connector device 1, here, a cable connector device will be described as an example, but the present invention is not limited to the cable connector device 1.

ハウジング２１にケーブル端子３０を取付ける際、ケーブル端子３０は、ハウジング２１の端子保持孔２２ｃに、挿入方向「α」に沿って、奥から手前に向かって図示矢印「α２」方向に挿入される。ケーブル端子３０には、補強部３２Ａの側縁３３を利用して、弾性変位可能なランス片３３ｂが形成されており、ケーブル端子３０が端子保持孔２２ｃに挿入される際、ランス片３３ｂは、その弾性を利用して端子保持孔２２ｃの底部内壁に設けた段部２４を乗り越えて、段部２４の前面２４ａに当接した状態でそこに嵌る。その後、ケーブル端子３０の側面に設けた切欠５４に挿入するように、ハウジング２１にリテーナ４を取付けることにより、ケーブル端子３０はハウジング２１の所定位置に固定され得る。ハウジング２１の所定位置に固定されたとき、ケーブル端子３０の端子挿入口５１ａは、ハウジング２１の端子挿入口２２ｂと整列し、相手端子が挿入される連通口を形成する。   When the cable terminal 30 is attached to the housing 21, the cable terminal 30 is inserted into the terminal holding hole 22 c of the housing 21 in the illustrated arrow “α2” direction from the back toward the front along the insertion direction “α”. The cable terminal 30 is formed with an elastically displaceable lance piece 33b using the side edge 33 of the reinforcing portion 32A. When the cable terminal 30 is inserted into the terminal holding hole 22c, the lance piece 33b is The elastic member is used to get over the stepped portion 24 provided on the inner wall of the bottom of the terminal holding hole 22c and fit into the stepped portion 24 in contact with the front surface 24a. Thereafter, the cable terminal 30 can be fixed at a predetermined position of the housing 21 by attaching the retainer 4 to the housing 21 so as to be inserted into the notch 54 provided on the side surface of the cable terminal 30. When fixed at a predetermined position of the housing 21, the terminal insertion port 51a of the cable terminal 30 is aligned with the terminal insertion port 22b of the housing 21 to form a communication port into which the mating terminal is inserted.

ケーブルコネクタ装置１は、ケーブルコネクタ２０と基板コネクタ１０の組から成る。但し、上の説明からも明らかなように、本発明は、ケーブルコネクタ２０と基板コネクタ１０の組に限定されるものではなく、種々のコネクタに適用することができる。例えば、基板コネクタ同士の組としてもよいし、ケーブルコネクタ同士の組としてもよい。   The cable connector device 1 includes a set of a cable connector 20 and a board connector 10. However, as is clear from the above description, the present invention is not limited to the set of the cable connector 20 and the board connector 10, and can be applied to various connectors. For example, it may be a set of board connectors or a set of cable connectors.

基板コネクタ１０は、主に、ハウジング１１と、ハウジング１１の内部に配列された端子７を備える。ハウジング１１は、該ハウジング１１に埋め込まれた実装用金具１２を利用して基板２に固定される。   The board connector 10 mainly includes a housing 11 and terminals 7 arranged inside the housing 11. The housing 11 is fixed to the substrate 2 by using mounting hardware 12 embedded in the housing 11.

ハウジング１１の前面に、ケーブルコネクタ２０を嵌合させる嵌合口１１ａが設けられている。嵌合口１１ａを通じてケーブルコネクタ２０が基板コネクタ１０に嵌入される際、ケーブルコネクタ２０の端子挿入口５１ａとハウジング２１の端子挿入口２２ｂの連通口を通じて、基板コネクタ１０の相手端子７が、ケーブル端子３０の端子挿入空間５１ｂに挿入され、相手端子７とケーブル端子３０が電気的に接続される。また、このときケーブルコネクタ２０のハウジング２１に設けたロック突部２２ａが、基板コネクタ１０のハウジング１１に設けたロック孔１１ｂに嵌り、ケーブルコネクタ２０は基板コネクタ１０に係止される。   A fitting port 11 a for fitting the cable connector 20 is provided on the front surface of the housing 11. When the cable connector 20 is inserted into the board connector 10 through the fitting port 11a, the mating terminal 7 of the board connector 10 is connected to the cable terminal 30 through the communication port of the terminal insertion port 51a of the cable connector 20 and the terminal insertion port 22b of the housing 21. The mating terminal 7 and the cable terminal 30 are electrically connected to each other. At this time, the lock protrusion 22 a provided on the housing 21 of the cable connector 20 fits into the lock hole 11 b provided on the housing 11 of the board connector 10, and the cable connector 20 is locked to the board connector 10.
