Description

本開示は、端子及びコネクタに関するものである。 The present disclosure relates to terminals and connectors.

従来、ＬＳＩ、ＣＰＵ等の半導体装置であってＰＧＡ（ＰｉｎＧｒｉｄＡｒｒａｙ）タイプの端子を備えるものは、プリント配線板等の回路基板に接続される場合、その端子が、前記回路基板に取付けられたソケットと呼ばれるコネクタを介して、回路基板の導電トレースに電気的に接続されるようになっている。そして、前記ソケットは、半導体装置のピン状の端子の各々に対応する複数の開口部が形成されたハウジングと、各開口部内に収容されて各ピン状の端子と係合する複数の端子とを備えている（例えば、特許文献１参照。）。 Conventionally, when a semiconductor device such as an LSI or a CPU having a PGA (Pin Grid Array) type terminal is connected to a circuit board such as a printed wiring board, the terminal is attached to the circuit board. It is electrically connected to the conductive trace of the circuit board via a connector called a socket. The socket includes a housing in which a plurality of openings corresponding to each of the pin-shaped terminals of the semiconductor device are formed, and a plurality of terminals housed in the openings and engaged with the pin-shaped terminals. (See, for example, Patent Document 1).

図９は従来のコネクタの端子を示す斜視図である。 FIG. 9 is a perspective view showing the terminals of the conventional connector.

図において、８５１は、図示されない回路基板上に搭載されるコネクタのハウジングに形成された複数の開口部の各々の内部に収容される端子であり、金属板に打抜き、曲げ等の加工を施すことによって作製されたものである。 In the figure, reference numeral 851 is a terminal accommodated inside each of a plurality of openings formed in a housing of a connector mounted on a circuit board (not shown), and the metal plate is punched, bent, or the like. It was made by.

そして、前記端子８５１は、平板状の支持部８５２と、該支持部８５２の上端に接続された屈曲した連結部８５３と、該連結部８５３の先端に接続された係合部８５４とを有する。なお、前記支持部８５２は、側方に分岐した分岐部８５２ａを含んでいる。 The terminal 851 has a flat plate-shaped support portion 852, a bent connecting portion 853 connected to the upper end of the support portion 852, and an engaging portion 854 connected to the tip end of the connecting portion 853. The support portion 852 includes a laterally branched branch portion 852a.

また、前記係合部８５４は、上端が前記連結部８５３の先端に接続された第１側部８５４ａと、該第１側部８５４ａの下端に接続された底部８５４ｂと、下端が前記底部８５４ｂに接続された第２側部８５４ｃとを含む略コ字状の部分である。なお、前記第１側部８５４ａと第２側部８５４ｃとは、前記係合部８５４の上端に形成された開口端８５４ｄに向けて漸次近接するように形成されている。さらに、該開口端８５４ｄの幅Ｗは、端子８５１が係合する図示されないピン状の端子の径よりも小さく、該ピン状の端子によって押広げられるように設定されている。そして、前記第１側部８５４ａ及び第２側部８５４ｃにおける開口端８５４ｄに対応する部分には、前記ピン状の端子を誘込む案内片８５４ｅが接続されている。 Further, the engaging portion 854 has a first side portion 854a whose upper end is connected to the tip of the connecting portion 853, a bottom portion 854b whose upper end is connected to the lower end of the first side portion 854a, and a lower end thereof to the bottom portion 854b. It is a substantially U-shaped portion including the connected second side portion 854c. The first side portion 854a and the second side portion 854c are formed so as to gradually approach the opening end 854d formed at the upper end of the engaging portion 854. Further, the width W of the open end 854d is set to be smaller than the diameter of the pin-shaped terminal (not shown) with which the terminal 851 engages, and is expanded by the pin-shaped terminal. A guide piece 854e for attracting the pin-shaped terminal is connected to a portion of the first side portion 854a and the second side portion 854c corresponding to the opening end 854d.

前記端子８５１がハウジングに形成された各開口部内に収容された状態では、前記支持部８５２及び分岐部８５２ａの下端は、前記開口部の底面を貫通する貫通孔に挿入されてハウジングの底面に到達し、これにより、前記端子８５１がハウジングに固定される。また、前記分岐部８５２ａの下端は、ハウジングが搭載されている回路基板の表面の接続パッドにはんだ付によって電気的に接続される。さらに、前記支持部８５２における係合部８５４と反対側の側面は、開口部の内壁面に当接する。そのため、前記ピン状の端子が開口端８５４ｄ内に挿入される際に係合部８５４が力を受けても、このような力が開口部の内壁面によって受止められるので、前記端子８５１の各部が変形したり、損傷を受けたりすることがない。 When the terminal 851 is housed in each opening formed in the housing, the lower ends of the support portion 852 and the branch portion 852a are inserted into a through hole penetrating the bottom surface of the opening and reach the bottom surface of the housing. As a result, the terminal 851 is fixed to the housing. Further, the lower end of the branch portion 852a is electrically connected to a connection pad on the surface of the circuit board on which the housing is mounted by soldering. Further, the side surface of the support portion 852 opposite to the engaging portion 854 abuts on the inner wall surface of the opening. Therefore, even if the engaging portion 854 receives a force when the pin-shaped terminal is inserted into the opening end 854d, such force is received by the inner wall surface of the opening, so that each portion of the terminal 851. Will not be deformed or damaged.

しかしながら、前記従来のコネクタにおいては、近年の電子機器における部材の小型化に十分に対応することができない。スマートフォンのようなモバイル通信機器や、ラップトップコンピュータ、タブレット、デジタルカメラ、音楽プレーヤ、ゲーム機、ナビゲーション装置等の電子機器においては、筐体の小型低背化及びそれに伴う各部品の小型低背化が要求されているが、前記従来のコネクタでは、端子８５１を収容する複数の開口部が形成されたハウジングの寸法が大きいので、コネクタの小型低背化の要求に十分に対応することができない。 However, the conventional connector cannot sufficiently cope with the miniaturization of members in recent electronic devices. In mobile communication devices such as smartphones and electronic devices such as laptop computers, tablets, digital cameras, music players, game consoles, and navigation devices, the housing is made smaller and shorter, and each component is made smaller and shorter. However, in the conventional connector, since the size of the housing in which a plurality of openings for accommodating the terminal 851 is formed is large, it is not possible to sufficiently meet the demand for miniaturization and low profile of the connector.

もっとも、ハウジングを省略することによって、前記従来のコネクタを小型低背化することも考えられる。しかし、その場合、前記端子８５１は、分岐部８５２ａの下端が回路基板の表面の接続パッドにはんだ付されることによってのみ支えられることになるので、前述のようにピン状の端子が開口端８５４ｄ内に挿入される際に係合部８５４が力を受けると、このような力によって、端子８５１の各部が変形したり、損傷を受けたりするか、又は、分岐部８５２ａの下端と回路基板の表面の接続パッドとのはんだ付部分が破断してしまう可能性がある。 However, it is also conceivable to reduce the size and height of the conventional connector by omitting the housing. However, in that case, the terminal 851 is supported only by soldering the lower end of the branch portion 852a to the connection pad on the surface of the circuit board, so that the pin-shaped terminal is the open end 854d as described above. If the engaging portion 854 receives a force when inserted into the terminal 851, each portion of the terminal 851 may be deformed or damaged, or the lower end of the branch portion 852a and the circuit board may be damaged. The soldered part with the connection pad on the surface may break.

ここでは、前記従来のコネクタの問題点を解決して、高いスペース効率で相手方コネクタとの接続を実現することができ、小型低背でありながら、相手方端子と嵌合する際に相手方端子から力を受けても、変形したり、損傷を受けたりすることがなく、電気的接続状態を安定的に維持することができ、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。 Here, the problem of the conventional connector can be solved and the connection with the other party connector can be realized with high space efficiency. It is an object of the present invention to provide highly reliable terminals and connectors that can stably maintain an electrical connection state without being deformed or damaged even if they are subjected to a shock.

そのために、端子においては、基板に固定される基板固定部と、相手方端子を挟持する一対の接触部と、前記基板固定部及び接触部に両端がそれぞれ接続された弾性変形部とを備え、該弾性変形部のばね定数が前記接触部のばね定数よりも小さい。 Therefore, the terminal is provided with a substrate fixing portion fixed to the substrate, a pair of contact portions sandwiching the mating terminal, and an elastically deformed portion having both ends connected to the substrate fixing portion and the contact portion. The spring constant of the elastically deformed portion is smaller than the spring constant of the contact portion.

他の端子においては、さらに、前記弾性変形部は、前記基板固定部及び接触部よりも板厚が薄い肉薄部を含む。 In the other terminals, the elastically deformed portion further includes a thin portion having a thinner plate thickness than the substrate fixing portion and the contact portion.

更に他の端子においては、さらに、各接触部は、前記弾性変形部の上端に接続され、前記基板固定部と平行に延在する基部と、該基部の下面から下方に向けて延在する接触腕部とを含み、各接触腕部は、下方に向うにつれて他方の接触腕部に接近するように傾斜する傾斜部を含む。 In yet another terminal, each contact portion is connected to the upper end of the elastically deformed portion and has a contact extending downward from the lower surface of the base portion with a base portion extending in parallel with the substrate fixing portion. Each contact arm includes an incline that inclines toward the other contact arm as it goes downward.

更に他の端子においては、さらに、前記弾性変形部は、前記基板固定部の基端に接続され、各基部は、その基端が前記弾性変形部に接続され、各接触腕部は、前記基部の基端と先端との中間位置から下方に向けて延在する。 In still another terminal, the elastically deformed portion is further connected to the base end of the substrate fixing portion, the base end of each base portion is connected to the elastically deformed portion, and each contact arm portion is connected to the base portion. It extends downward from the intermediate position between the base end and the tip of the.

更に他の端子においては、さらに、各基部は、その基端が前記弾性変形部に接続され、その先端はＵ字状の連結部によって他方の基部の先端と連結されている。 In still other terminals, the base of each base is connected to the elastically deformed portion, and the tip thereof is connected to the tip of the other base by a U-shaped connecting portion.

更に他の端子においては、さらに、各基部は、その基端が他のＵ字状の連結部によって他方の基部の基端と連結され、平面視において、一対の基部と一対の連結部とによって周囲を画定された開口部には、前記相手方端子が進入して、前記端子と嵌合する。 At yet another terminal, each base is further coupled to the base of the other base by another U-shaped connecting portion, and in plan view by a pair of bases and a pair of connecting portions. The mating terminal enters the opening defined by the periphery and fits with the terminal.

更に他の端子においては、さらに、前記基板固定部及び弾性変形部は、それぞれ、一対である。 In the other terminals, the substrate fixing portion and the elastically deforming portion are each paired.

コネクタにおいては、相手方端子と嵌合する端子と、該端子が表面に接続された基板とを備えるコネクタであって、前記端子は、前記基板に固定される基板固定部と、前記相手方端子を挟持する一対の接触部と、前記基板固定部及び接触部に両端がそれぞれ接続された弾性変形部とを含み、該弾性変形部のばね定数が前記接触部のばね定数よりも小さい。 The connector is a connector including a terminal that fits with the mating terminal and a board to which the terminal is connected to the surface, and the terminal sandwiches the board fixing portion fixed to the board and the mating terminal. A pair of contact portions and an elastically deformed portion having both ends connected to the substrate fixing portion and the contact portion are included, and the spring constant of the elastically deformed portion is smaller than the spring constant of the contact portion.

本開示によれば、高いスペース効率で相手方コネクタとの接続を実現することができ、小型低背でありながら、相手方端子と嵌合する際に相手方端子から力を受けても、端子が変形したり、損傷を受けたりすることがなく、電気的接続状態を安定的に維持することができ、信頼性が向上する。 According to the present disclosure, it is possible to realize a connection with a mating connector with high space efficiency, and despite its small size and low profile, the terminal is deformed even if a force is received from the mating terminal when mating with the mating terminal. It can maintain a stable electrical connection without being damaged or damaged, and reliability is improved.

図において、１は本実施の形態におけるコネクタであって、基板１１と、該基板１１の表面に機械的及び電気的に接続された端子５１とを備え、相手方コネクタ１０１と互いに嵌合される。また、該相手方コネクタ１０１は、相手方基板１１１と、該相手方基板１１１の表面に機械的及び電気的に接続された相手方端子１５１とを備える。 In the figure, reference numeral 1 denotes a connector according to the present embodiment, which includes a substrate 11 and a terminal 51 mechanically and electrically connected to the surface of the substrate 11 and is fitted to each other with the mating connector 101. Further, the mating connector 101 includes a mating board 111 and a mating terminal 151 mechanically and electrically connected to the surface of the mating board 111.

本実施の形態におけるコネクタ１は、例えば、スマートフォンのようなモバイル通信機器や、ラップトップコンピュータ、タブレット、デジタルカメラ、音楽プレーヤ、ゲーム機、ナビゲーション装置等の電子機器において、プリント回路基板等の基板同士を接続したり、ＬＳＩ、ＣＰＵ等の半導体装置と基板との間でパッド間隔を調整するインターポーザを基板に接続したりするために用いられるものである。したがって、相手方基板１１１は、基板１１と同様の基板であってもよいし、インターポーザであってもよいが、ここでは、基板１１と同様の基板である場合について説明する。なお、前記基板１１及び相手方基板１１１は、例えば、電子機器等に使用されるプリント回路基板、フレキシブルフラットケーブル（ＦＦＣ）、フレキシブル回路基板（ＦＰＣ）等であるが、平板状の電気回路を有するものであれば、いかなる種類の基板であってもよい。 The connector 1 in the present embodiment is, for example, a substrate such as a printed circuit board in a mobile communication device such as a smartphone or an electronic device such as a laptop computer, a tablet, a digital camera, a music player, a game machine, or a navigation device. Is used, or an interposer for adjusting a pad spacing between a semiconductor device such as an LSI or a CPU and a substrate is connected to the substrate. Therefore, the mating substrate 111 may be the same substrate as the substrate 11 or may be an interposer, but here, the case where the substrate is the same as the substrate 11 will be described. The substrate 11 and the mating substrate 111 are, for example, a printed circuit board, a flexible flat cable (FFC), a flexible circuit board (FPC), etc. used for electronic devices and the like, but have a flat plate-shaped electric circuit. Any kind of substrate may be used as long as it is used.

また、本実施の形態において、コネクタ１及び相手方コネクタ１０１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、前記コネクタ１及び相手方コネクタ１０１の各部が図に示される姿勢である場合に適切であるが、そ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。 Further, in the present embodiment, the expressions indicating the directions of upper, lower, left, right, front, back, etc. used to explain the configuration and operation of each part of the connector 1 and the mating connector 101 are absolute. It is not a thing but a relative one, and is appropriate when each part of the connector 1 and the mating connector 101 is in the posture shown in the figure, but when the posture is changed, it is changed according to the change in the posture. Should be interpreted.

そして、前記コネクタ１は、基板１１、及び、該基板１１の表面に接続された端子５１のみを備え、一般的なコネクタが備える合成樹脂等の絶縁性材料から成るハウジングであって、前記端子５１を収容又は保持するようなハウジングを備えていない。なお、図に示される例において、端子５１は、４つであって、平面視（Ｘ－Ｙ平面上）において、長方形の各頂点に位置するように配置されているが、端子５１の数及び配置の形態は、これに限定されるものでなく、任意に変更することができる。また、前記端子５１は、好適には、縦横高さの各寸法が０．３～１．０〔ｍｍ〕程度であるが、端子５１の各寸法は、これに限定されるものでなく、任意に変更することができる。さらに、前記基板１１の表面には、図示されない基板１１の電気回路に接続された長方形状の接続パッド６１が形成されている。該接続パッド６１の形状、寸法、数及び配置の形態は、端子５１の形状、寸法、数及び配置の形態に適合するように設定される。 The connector 1 includes only the substrate 11 and the terminal 51 connected to the surface of the substrate 11, and is a housing made of an insulating material such as synthetic resin provided by a general connector, and the terminal 51 is provided. Does not have a housing to accommodate or hold. In the example shown in the figure, there are four terminals 51, which are arranged so as to be located at each vertex of the rectangle in a plan view (on the XY plane), but the number of terminals 51 and the number of terminals 51 The form of arrangement is not limited to this, and can be arbitrarily changed. Further, the terminal 51 preferably has vertical and horizontal height dimensions of about 0.3 to 1.0 [mm], but the terminal 51 dimensions are not limited to this and are arbitrary. Can be changed to. Further, on the surface of the substrate 11, a rectangular connection pad 61 connected to an electric circuit of the substrate 11 (not shown) is formed. The shape, dimensions, number, and arrangement of the connection pads 61 are set to match the shape, dimensions, number, and arrangement of the terminals 51.

各端子５１は、好適には、導電性の金属板に打抜き、曲げ等の加工を施すことによって一体的に作製されたものであり、具体的には、図４Ａ～４Ｃに示されるように、一対の基板固定部５２と、該基板固定部５２から上方（Ｚ軸正方向）に向けて延在する一対の弾性変形部５３と、該弾性変形部５３の上端に接続された一対の接触部５４と、各接触部５４同士を連結する一対の連結部５５とを有する。また、平面視において、一対の接触部５４と一対の連結部５５とによって周囲を画定された空間は、相手方端子１５１が進入する開口部５６となっている。そして、前記端子５１は、概略、その幅方向（Ｙ軸方向）中心を通るＸ－Ｚ平面を対称面とした面対称となるような全体形状を有する。 Each terminal 51 is preferably integrally manufactured by punching, bending, or the like on a conductive metal plate, and specifically, as shown in FIGS. 4A to 4C. A pair of substrate fixing portions 52, a pair of elastically deformed portions 53 extending upward (Z-axis positive direction) from the substrate fixing portion 52, and a pair of contact portions connected to the upper ends of the elastically deformed portions 53. It has a 54 and a pair of connecting portions 55 that connect the contact portions 54 to each other. Further, in a plan view, the space defined by the pair of contact portions 54 and the pair of connecting portions 55 is an opening 56 into which the mating terminal 151 enters. The terminal 51 has an overall shape that is plane-symmetrical with the XX plane passing through the center in the width direction (Y-axis direction) as the plane of symmetry.

前記一対の基板固定部５２は、各々が基板１１の長手方向（Ｘ軸方向）に延在する角柱状の部分であって、互いに平行となるように並べられている。ここでは、一方の基板固定部５２を第１基板固定部５２Ａと称し、他方の基板固定部５２を第２基板固定部５２Ｂと称することとする。なお、第１基板固定部５２Ａと第２基板固定部５２Ｂとを統合的に説明する場合には、基板固定部５２として説明する。 The pair of substrate fixing portions 52 are prismatic portions extending in the longitudinal direction (X-axis direction) of the substrate 11, and are arranged so as to be parallel to each other. Here, one substrate fixing portion 52 is referred to as a first substrate fixing portion 52A, and the other substrate fixing portion 52 is referred to as a second substrate fixing portion 52B. When the first board fixing portion 52A and the second board fixing portion 52B are described in an integrated manner, they will be described as the board fixing portion 52.

図に示される例において、第１基板固定部５２Ａは、切欠き５２ｂより前方の先端延長部５２ａを含み、該先端延長部５２ａの分だけ、第２基板固定部５２Ｂよりも長手方向の寸法が大きくなっている。第１基板固定部５２Ａ及び第２基板固定部５２Ｂの後端（図４Ｃにおける右端）の位置が互いに等しいので、第１基板固定部５２Ａの先端、すなわち、前端は第２基板固定部５２Ｂの前端よりも前方（Ｘ軸正方向）に位置する。これにより、製造工程において、作製された端子５１を図示されない金属板から成る金属キャリアから切断して分離する際に、先端延長部５２ａを把持することによって該先端延長部５２ａの先端と金属キャリアとの境界部を容易に切断することができ、作業性が向上する。なお、前記先端延長部５２ａは、適宜省略することもできる。 In the example shown in the figure, the first substrate fixing portion 52A includes the tip extension portion 52a in front of the notch 52b, and the dimension in the longitudinal direction is larger than that of the second substrate fixing portion 52B by the amount of the tip extension portion 52a. It's getting bigger. Since the positions of the rear ends (right end in FIG. 4C) of the first board fixing portion 52A and the second board fixing portion 52B are equal to each other, the tip of the first board fixing portion 52A, that is, the front end is the front end of the second board fixing portion 52B. It is located in front of (X-axis positive direction). As a result, in the manufacturing process, when the manufactured terminal 51 is cut from a metal carrier made of a metal plate (not shown) and separated, the tip of the tip extension portion 52a and the metal carrier are gripped by gripping the tip extension portion 52a. The boundary portion of the metal can be easily cut, and workability is improved. The tip extension portion 52a may be omitted as appropriate.

各端子５１の一対の基板固定部５２は、図１及び３Ａに示されるように、その底面が基板１１表面上の対応する接続パッド６１の表面に対向した状態で、はんだ付によって接続パッド６１の表面に機械的及び電気的に接続される。なお、図に示される例において、第１基板固定部５２Ａの先端延長部５２ａは、接続パッド６１の表面に接続されていない。 As shown in FIGS. 1 and 3A, the pair of board fixing portions 52 of each terminal 51 are soldered to the connection pad 61 with the bottom surface facing the surface of the corresponding connection pad 61 on the surface of the board 11. Mechanically and electrically connected to the surface. In the example shown in the figure, the tip extension portion 52a of the first substrate fixing portion 52A is not connected to the surface of the connection pad 61.

前記一対の弾性変形部５３は、各々が各基板固定部５２の基端、すなわち、後端における上面から上方に向けて延在する角柱状の部分であって、互いに平行となるように並べられている。ここでは、第１基板固定部５２Ａに接続された弾性変形部５３を第１弾性変形部５３Ａと称し、第２基板固定部５２Ｂに接続された弾性変形部５３を第２弾性変形部５３Ｂと称することとする。なお、第１弾性変形部５３Ａと第２弾性変形部５３Ｂとを統合的に説明する場合には、弾性変形部５３として説明する。 Each of the pair of elastically deformed portions 53 is a base end of each substrate fixing portion 52, that is, a prismatic portion extending upward from the upper surface at the rear end, and is arranged so as to be parallel to each other. ing. Here, the elastic deforming portion 53 connected to the first substrate fixing portion 52A is referred to as a first elastic deforming portion 53A, and the elastic deforming portion 53 connected to the second substrate fixing portion 52B is referred to as a second elastic deforming portion 53B. I will do it. When the first elastic deformation portion 53A and the second elastic deformation portion 53B are described in an integrated manner, the first elastic deformation portion 53A and the second elastic deformation portion 53B will be described as the elastic deformation portion 53.

各弾性変形部５３は、肉薄部としての窪み部５３ａと、該窪み部５３ａの下端に接続された下側傾斜部５３ｂと、前記窪み部５３ａの上端に接続された上側傾斜部５３ｃとを含んでいる。前記窪み部５３ａは、プレス等の加工を施すことによって作製された厚さ方向（Ｙ軸方向）の寸法が小さい肉薄の部分であって、基板固定部５２、接触部５４及び連結部５５よりも板厚が薄くなるように形成されている。図に示される例において、前記窪み部５３ａは、弾性変形部５３の内側面（一対の弾性変形部５３同士が互いに対向する側の面）を窪ませて形成され、弾性変形部５３の外側面は、平坦で基板固定部５２及び接触部５４の外側面と面一となっているが、前記窪み部５３ａを弾性変形部５３の外側面に形成することもできる。 Each elastically deformed portion 53 includes a recessed portion 53a as a thin portion, a lower inclined portion 53b connected to the lower end of the recessed portion 53a, and an upper inclined portion 53c connected to the upper end of the recessed portion 53a. I'm out. The recessed portion 53a is a thin portion having a small thickness direction (Y-axis direction) produced by processing such as pressing, and is larger than the substrate fixing portion 52, the contact portion 54, and the connecting portion 55. It is formed so that the plate thickness becomes thin. In the example shown in the figure, the recessed portion 53a is formed by recessing the inner side surface of the elastically deformed portion 53 (the surface on the side where the pair of elastically deformed portions 53 face each other), and the outer surface of the elastically deformed portion 53. Is flat and flush with the outer surfaces of the substrate fixing portion 52 and the contact portion 54, but the recessed portion 53a can also be formed on the outer surface of the elastically deformed portion 53.

そして、前記窪み部５３ａは、各弾性変形部５３のほとんどを占める範囲に形成されるので、各弾性変形部５３のほとんどの部分は、基板固定部５２、接触部５４及び連結部５５よりも板厚が薄くなっている。したがって、前記弾性変形部５３は、基板固定部５２、接触部５４及び連結部５５よりも、柔軟であり、弾性変形しやすくなっている。特に、基板１１の短手方向（Ｙ軸方向）の力を受けた場合、弾性変形部５３の断面係数が厚さ方向（Ｙ軸方向）の寸法の二乗に比例し、断面二次モーメントが厚さ方向の寸法の三乗に比例するので、厚さ方向の寸法が小さい前記弾性変形部５３は、前記力を受けた方向に弾性変形しやすくなっている。 Since the recessed portion 53a is formed in a range that occupies most of the elastically deformed portions 53, most of the elastically deformed portions 53 are more plates than the substrate fixing portion 52, the contact portion 54, and the connecting portion 55. The thickness is getting thinner. Therefore, the elastically deformed portion 53 is more flexible than the substrate fixing portion 52, the contact portion 54, and the connecting portion 55, and is easily elastically deformed. In particular, when a force is applied to the substrate 11 in the lateral direction (Y-axis direction), the geometrical moment of inertia of the elastically deformed portion 53 is proportional to the square of the dimension in the thickness direction (Y-axis direction), and the moment of inertia of area is thick. Since it is proportional to the cube of the dimension in the radial direction, the elastically deformed portion 53 having a small dimension in the thickness direction is likely to be elastically deformed in the direction in which the force is applied.

また、前記下側傾斜部５３ｂは、下端が基板固定部５２に接続された部分であって、板厚が基板固定部５２の寸法から窪み部５３ａの寸法にまで、上方に向うにつれて、漸減する部分である。さらに、前記上側傾斜部５３ｃは、上端が接触部５４に接続された部分であって、板厚が接触部５４の寸法から窪み部５３ａの寸法にまで、下方に向うにつれて、漸減する部分である。 Further, the lower inclined portion 53b is a portion whose lower end is connected to the substrate fixing portion 52, and the plate thickness gradually decreases as the plate thickness increases from the dimension of the substrate fixing portion 52 to the dimension of the recessed portion 53a. It is a part. Further, the upper inclined portion 53c is a portion whose upper end is connected to the contact portion 54, and the plate thickness gradually decreases from the dimension of the contact portion 54 to the dimension of the recessed portion 53a as it goes downward. ..

前記一対の接触部５４の各々は、互いに平行に、かつ、各基板固定部５２と平行に基板１１の長手方向に延在する角柱状の部材であってその基端、すなわち、後端（図４Ｃにおける右端）が各弾性変形部５３の上端、すなわち、上側傾斜部５３ｃの上端に接続された基部５４ａと、該基部５４ａの下面から下方に向けて延在する接触腕部５４ｂとを含んでいる。ここでは、第１弾性変形部５３Ａに接続された接触部５４を第１接触部５４Ａと称し、第２弾性変形部５３Ｂに接続された接触部５４を第２接触部５４Ｂと称することとする。なお、第１接触部５４Ａと第２接触部５４Ｂとを統合的に説明する場合には、接触部５４として説明する。 Each of the pair of contact portions 54 is a prismatic member extending in the longitudinal direction of the substrate 11 in parallel with each other and in parallel with each substrate fixing portion 52, and the base end, that is, the rear end thereof (FIG. The right end in 4C) includes the upper end of each elastically deformed portion 53, that is, the base portion 54a connected to the upper end of the upper inclined portion 53c, and the contact arm portion 54b extending downward from the lower surface of the base portion 54a. There is. Here, the contact portion 54 connected to the first elastically deformed portion 53A is referred to as a first contact portion 54A, and the contact portion 54 connected to the second elastically deformed portion 53B is referred to as a second contact portion 54B. When the first contact portion 54A and the second contact portion 54B are described in an integrated manner, the first contact portion 54A and the second contact portion 54B will be described as the contact portion 54.

図に示される例において、第２接触部５４Ｂは、基部５４ａの先端、すなわち、前端（図４Ｃにおける左端）において下面から下方に向けて延在する下方凸部５４ａ１を含んでいる。該下方凸部５４ａ１の上下方向（Ｚ軸方向）の寸法は、接触腕部５４ｂよりも小さくなっている。なお、前記下方凸部５４ａ１は、適宜省略することもできる。 In the example shown in the figure, the second contact portion 54B includes a downward convex portion 54a1 extending downward from the lower surface at the tip end of the base portion 54a, that is, the front end (left end in FIG. 4C). The vertical dimension (Z-axis direction) of the downward convex portion 54a1 is smaller than that of the contact arm portion 54b. The downward convex portion 54a1 may be omitted as appropriate.

各接触腕部５４ｂは、基部５４ａの前端と後端との中間位置において、前記基部５４ａの下面に接続されている。そして、各接触腕部５４ｂは、前記基部５４ａの下面に上端が接続された基端部５４ｂ１と、該基端部５４ｂ１の下端に上端が接続され、図４Ｂに明確に示されるように、下方に向うにつれて他方の接触腕部５４ｂに接近するように傾斜する傾斜部５４ｂ２と、該傾斜部５４ｂ２の下端に上端が接続され、下方に向けて延在する先端部５４ｂ３とを含んでいる。なお、前記接触腕部５４ｂの各部の板厚は、均一であり、かつ、基部５４ａの板厚とも同一である。前記接触腕部５４ｂは、相手方端子１５１の接触部１５４と接触する部分であり、一対の接触腕部５４ｂ同士の間に、相手方端子１５１の接触部１５４が上方から下向きに相対的に移動して進入する。そして、互いに対向する先端部５４ｂ３の間隔（Ｙ軸方向の間隔）が前記相手方端子１５１における基板１１の短手方向（Ｙ軸方向）の外寸よりも小さく設定されているので、互いに対向する先端部５４ｂ３の間隔は、前記相手方端子１５１の接触部１５４によって弾性的に押広げられる。これにより、前記接触腕部５４ｂがばね力を発揮するので、相手方端子１５１の接触部１５４は、基板１１の短手方向の両側から前記接触腕部５４ｂによって挟持され、該接触腕部５４ｂと確実に接触して導通する。 Each contact arm portion 54b is connected to the lower surface of the base portion 54a at an intermediate position between the front end and the rear end of the base portion 54a. Each of the contact arm portions 54b has a base end portion 54b1 having an upper end connected to the lower surface of the base portion 54a and an upper end connected to the lower end of the base end portion 54b1. It includes an inclined portion 54b2 that inclines toward the other contact arm portion 54b toward the end, and a tip portion 54b3 having an upper end connected to the lower end of the inclined portion 54b2 and extending downward. The plate thickness of each portion of the contact arm portion 54b is uniform and is the same as the plate thickness of the base portion 54a. The contact arm portion 54b is a portion that comes into contact with the contact portion 154 of the mating terminal 151, and the contact portion 154 of the mating terminal 151 moves relatively downward from above between the pair of contact arm portions 54b. enter in. Since the distance between the tip portions 54b3 facing each other (distance in the Y-axis direction) is set to be smaller than the outer dimension in the lateral direction (Y-axis direction) of the substrate 11 in the mating terminal 151, the tips facing each other are set. The distance between the portions 54b3 is elastically expanded by the contact portion 154 of the mating terminal 151. As a result, the contact arm portion 54b exerts a spring force, so that the contact portion 154 of the mating terminal 151 is sandwiched by the contact arm portions 54b from both sides in the lateral direction of the substrate 11, and is surely connected to the contact arm portion 54b. Contact and conduct.

なお、前記基部５４ａ及び接触腕部５４ｂを含む接触部５４は、厚さ方向の寸法が基板固定部５２及び連結部５５と同一であって、弾性変形部５３の窪み部５３ａの厚さ方向の寸法よりも大きくなっているので、基板１１の短手方向の力を受けた場合には、弾性変形部５３よりも断面二次係数が大きいので、弾性変形部５３よりも変形しにくい。 The contact portion 54 including the base portion 54a and the contact arm portion 54b has the same dimensions in the thickness direction as the substrate fixing portion 52 and the connecting portion 55, and is in the thickness direction of the recessed portion 53a of the elastic deformation portion 53. Since it is larger than the size, it is less likely to be deformed than the elastically deformed portion 53 because the moment of inertia of area is larger than that of the elastically deformed portion 53 when a force in the lateral direction of the substrate 11 is applied.

また、該弾性変形部５３は、基板固定部５２の後端から上方に向けて延在し、基部５４ａは、弾性変形部５３の上端から前方に向けて延在し、接触腕部５４ｂは、基部５４ａの前端と後端との中間位置から下方に向けて延在しているので、基板固定部５２の下面から、弾性変形部５３、基部５４ａ及び接触腕部５４ｂの表面をたどって接触腕部５４ｂの先端近傍にまで到達する経路の長さが長くなっている。したがって、基板固定部５２の下面から、はんだやフラックスが、前記経路をたどって、接触腕部５４ｂと相手方端子１５１の接触部１５４との接触部分に到達することが、効果的に防止される。このように、はんだ上りやフラックス上りが生じないので、接触腕部５４ｂと相手方端子１５１の接触部１５４との導通状態が良好に維持される。 Further, the elastically deformed portion 53 extends upward from the rear end of the substrate fixing portion 52, the base portion 54a extends forward from the upper end of the elastically deformed portion 53, and the contact arm portion 54b extends forward. Since it extends downward from the intermediate position between the front end and the rear end of the base portion 54a, the contact arm traces the surfaces of the elastically deformed portion 53, the base portion 54a, and the contact arm portion 54b from the lower surface of the substrate fixing portion 52. The length of the path reaching the vicinity of the tip of the portion 54b is long. Therefore, it is effectively prevented from the lower surface of the substrate fixing portion 52 that the solder or the flux follows the path to reach the contact portion between the contact arm portion 54b and the contact portion 154 of the mating terminal 151. As described above, since solder rise and flux rise do not occur, the conduction state between the contact arm portion 54b and the contact portion 154 of the mating terminal 151 is maintained in a good state.

前記一対の連結部５５の各々は、角柱状の部材を基板１１の長手方向に観て、すなわち、Ｙ－Ｚ平面上において、概略Ｕ字を逆さにしたような形状となるように湾曲させたものであって、平面視（Ｘ－Ｙ平面上）において、基板１１の短手方向（Ｙ軸方向）に延在して互いに平行となるように並べられ、一対の接触部５４の基部５４ａの前端同士及び後端同士をそれぞれ連結する。ここでは、接触部５４の基部５４ａの前端同士を連結する連結部５５を第１連結部５５Ａと称し、接触部５４の基部５４ａの後端同士を連結する連結部５５を第２連結部５５Ｂと称することとする。前記第１連結部５５Ａの両端は、基部５４ａの前端における上面に接続され、前記第２連結部５５Ｂの両端は、基部５４ａの後端における上面に接続されている。なお、第１連結部５５Ａと第２連結部５５Ｂとを統合的に説明する場合には、連結部５５として説明する。 Each of the pair of connecting portions 55 is curved so that the prismatic member is viewed in the longitudinal direction of the substrate 11, that is, on the YZ plane, the shape is substantially upside down in a U shape. In a plan view (on the XY plane), the substrate 11 extends in the lateral direction (Y-axis direction) and is arranged so as to be parallel to each other, and the base portion 54a of the pair of contact portions 54 The front ends and the rear ends are connected to each other. Here, the connecting portion 55 that connects the front ends of the base portion 54a of the contact portion 54 is referred to as a first connecting portion 55A, and the connecting portion 55 that connects the rear ends of the base portion 54a of the contact portion 54 is referred to as a second connecting portion 55B. I will call it. Both ends of the first connecting portion 55A are connected to the upper surface at the front end of the base portion 54a, and both ends of the second connecting portion 55B are connected to the upper surface at the rear end of the base portion 54a. When the first connecting portion 55A and the second connecting portion 55B are described in an integrated manner, the first connecting portion 55A and the second connecting portion 55B will be described as the connecting portion 55.

このように、一対の接触部５４の基部５４ａの前端同士及び後端同士が、それぞれ、連結部５５によって連結されているので、相手方端子１５１の接触部１５４が一対の接触腕部５４ｂ同士の間に進入する際に、前記相手方端子１５１の接触部１５４から、一対の接触部５４の間隔を押広げるような力を受けても、互いに対向する基部５４ａの間隔が押広げられることがない。したがって、相手方端子１５１の接触部１５４が一対の接触腕部５４ｂ同士の間に進入する際には、主として、概略上下方向に延在する細長いカンチレバー状の接触腕部５４ｂが弾性的に変形して、互いに対向する先端部５４ｂ３の間隔が押広げられる。 In this way, the front ends and the rear ends of the base portion 54a of the pair of contact portions 54 are connected to each other by the connecting portion 55, so that the contact portion 154 of the mating terminal 151 is between the pair of contact arm portions 54b. Even if the contact portion 154 of the other terminal 151 receives a force that expands the distance between the pair of contact portions 54, the distance between the base portions 54a facing each other is not expanded. Therefore, when the contact portion 154 of the mating terminal 151 enters between the pair of contact arm portions 54b, the elongated cantilever-shaped contact arm portion 54b extending substantially in the vertical direction is elastically deformed. , The distance between the tip portions 54b3 facing each other is widened.

なお、相手方端子１５１の接触部１５４が一対の接触腕部５４ｂ同士の間に進入する際に、一対の接触腕部５４ｂは前記相手方端子１５１の接触部１５４から下向きの力も受けるところ、接触腕部５４ｂが基部５４ａの前端と後端との中間位置において基部５４ａに接続され、基部５４ａの後端のみが弾性変形部５３によって下方から支持されているのであるから、該弾性変形部５３には、その上端を前方に変位させるような曲げ力が作用する。しかし、基板１１の長手方向（Ｘ軸方向）の力を受けた場合、弾性変形部５３は、前後方向（Ｘ軸方向）の寸法が厚さ方向（Ｙ軸方向）の寸法よりも大きく、かつ、その場合の弾性変形部５３の断面二次係数が前後方向の寸法の二乗に比例するので、前記弾性変形部５３は、その上端が前方に変位するようには曲がりにくくなっている。なお、連結部５５によって互いに連結された一対の接触部５４を支持するのに十分であれば、弾性変形部５３及び基板固定部５２は、必ずしも一対のものである必要はなく、片側のみであってもよい。 When the contact portion 154 of the mating terminal 151 enters between the pair of contact arm portions 54b, the pair of contact arm portions 54b also receive a downward force from the contact portion 154 of the mating terminal 151. Since the 54b is connected to the base portion 54a at an intermediate position between the front end and the rear end of the base portion 54a, and only the rear end of the base portion 54a is supported from below by the elastic deformation portion 53, the elastic deformation portion 53 may be connected to the elastic deformation portion 53. A bending force that displaces the upper end forward acts. However, when a force is applied in the longitudinal direction (X-axis direction) of the substrate 11, the elastic deformation portion 53 has a dimension in the front-rear direction (X-axis direction) larger than a dimension in the thickness direction (Y-axis direction). In that case, since the quadratic coefficient of the cross section of the elastically deformed portion 53 is proportional to the square of the dimension in the front-rear direction, the elastically deformed portion 53 is difficult to bend so that its upper end is displaced forward. If it is sufficient to support the pair of contact portions 54 connected to each other by the connecting portion 55, the elastic deformation portion 53 and the substrate fixing portion 52 do not necessarily have to be a pair, but only on one side. You may.

また、前記相手方コネクタ１０１は、相手方基板１１１及び相手方端子１５１に加えて、端子保持部材１２１を更に備える。なお、図に示される例において、相手方端子１５１は、４つであって、平面視（Ｘ－Ｙ平面上）において、長方形の各頂点に位置するように配置されているが、相手方端子１５１の数及び配置の形態は、これに限定されるものでなく、コネクタ１の端子５１の数及び配置の形態に適合するように、変更することができる。さらに、前記相手方基板１１１の表面には、図示されない相手方基板１１１の電気回路に接続された円形状の相手方接続パッド１６１が形成されている。該相手方接続パッド１６１の形状、寸法、数及び配置の形態は、相手方端子１５１の形状、寸法、数及び配置の形態に適合するように設定される。 Further, the mating connector 101 further includes a terminal holding member 121 in addition to the mating board 111 and the mating terminal 151. In the example shown in the figure, there are four mating terminals 151, which are arranged so as to be located at each vertex of the rectangle in a plan view (on the XY plane). The form of the number and arrangement is not limited to this, and can be changed so as to match the form of the number and arrangement of the terminals 51 of the connector 1. Further, on the surface of the mating substrate 111, a circular mating connecting pad 161 connected to an electric circuit of the mating substrate 111 (not shown) is formed. The shape, dimension, number, and arrangement of the mating connection pad 161 are set so as to match the shape, dimension, number, and arrangement of the mating terminal 151.

そして、本実施の形態における相手方端子１５１は、好適には、導電性の金属の棒状材に切削、転造、切断等の加工を施すことによって一体的に作製されたものであり、具体的には、図２及び３Ｂに示されるように、基板固定部１５２と、該基板固定部１５２から下方（Ｚ軸負方向）に向けて延在する接触部１５４とを有する。 The mating terminal 151 in the present embodiment is preferably integrally manufactured by subjecting a conductive metal rod-shaped material to processing such as cutting, rolling, and cutting. Has a substrate fixing portion 152 and a contact portion 154 extending downward (Z-axis negative direction) from the substrate fixing portion 152 as shown in FIGS. 2 and 3B.

図に示される例において、前記基板固定部１５２は、厚板の円板状の部材であって、その直径が相手方接続パッド１６１の直径よりも小さく設定されている。そして、前記基板固定部１５２は、図３Ｂに示されるように、その底面（接触部１５４と反対側の面）が相手方基板１１１表面上の対応する相手方接続パッド１６１の表面に対向した状態で、はんだ付によって相手方接続パッド１６１の表面に機械的及び電気的に接続される。また、前記接触部１５４は、円柱状の部材であって、その外径は、基板固定部１５２の外径より小さく、さらに、コネクタ１の端子５１における開口部５６の周囲を画定する一対の連結部５５同士の間隔及び一対の接触部５４の基部５４ａ同士の間隔より小さく、かつ、互いに対向する先端部５４ｂ３の間隔より大きくなるように設定されている。 In the example shown in the figure, the substrate fixing portion 152 is a disk-shaped member of a thick plate, and its diameter is set to be smaller than the diameter of the mating connection pad 161. Then, as shown in FIG. 3B, the substrate fixing portion 152 has its bottom surface (the surface opposite to the contact portion 154) facing the surface of the corresponding counterpart connection pad 161 on the surface of the counterpart substrate 111. It is mechanically and electrically connected to the surface of the mating connection pad 161 by soldering. Further, the contact portion 154 is a columnar member whose outer diameter is smaller than the outer diameter of the substrate fixing portion 152, and further, a pair of connections defining the periphery of the opening 56 in the terminal 51 of the connector 1. It is set to be smaller than the distance between the portions 55 and the distance between the base portions 54a of the pair of contact portions 54, and larger than the distance between the tip portions 54b3 facing each other.

前記端子保持部材１２１は、合成樹脂等の絶縁性材料から成る部材であって、平面形状が長方形状の厚板状の部材であり、前記端子保持部材１２１を板厚方向に貫通する貫通孔１２１ａが形成されている。該貫通孔１２１ａの形状、寸法、数及び配置の形態は、相手方端子１５１の形状、寸法、数及び配置の形態に適合するように設定される。そして、各相手方端子１５１の接触部１５４は、対応する貫通孔１２１ａに挿入されて保持される。なお、前記貫通孔１２１ａの内径は接触部１５４の直径よりもわずかに小さい程度に設定されることが望ましく、これにより、接触部１５４は、貫通孔１２１ａに圧入された状態となり、安定的に保持される。 The terminal holding member 121 is a member made of an insulating material such as synthetic resin, and is a thick plate-shaped member having a rectangular planar shape, and is a through hole 121a penetrating the terminal holding member 121 in the plate thickness direction. Is formed. The shape, size, number, and arrangement of the through holes 121a are set so as to match the shape, size, number, and arrangement of the mating terminal 151. Then, the contact portion 154 of each mating terminal 151 is inserted into and held in the corresponding through hole 121a. It is desirable that the inner diameter of the through hole 121a is set to a degree slightly smaller than the diameter of the contact portion 154, whereby the contact portion 154 is in a state of being press-fitted into the through hole 121a and is stably held. Will be done.

なお、前記基板固定部１５２、接触部１５４及び貫通孔１２１ａの断面形状は、必ずしも、図に示される例のように円形である必要はなく、例えば、正方形、六角形、八角形等の形状であってもよいが、ここでは、円形である場合について説明する。 The cross-sectional shape of the substrate fixing portion 152, the contact portion 154, and the through hole 121a does not necessarily have to be circular as in the example shown in the figure, and may be, for example, a square shape, a hexagonal shape, an octagonal shape, or the like. It may be present, but here, the case where it is circular will be described.

また、前記相手方コネクタ１０１を組立てる際には、望ましくは、まず、各相手方端子１５１の接触部１５４を端子保持部材１２１の対応する貫通孔１２１ａに挿入して、所定の長さだけ接触部１５４の先端を貫通孔１２１ａから突出させる。これにより、各相手方端子１５１は、基板固定部１５２の底面が互いにほぼ面一となった状態で、かつ、配置の形態が相手方接続パッド１６１の形態と同様になった状態で端子保持部材１２１によって保持される。そして、端子保持部材１２１によって保持された状態の複数の相手方端子１５１の基板固定部１５２の底面を、相手方基板１１１の相手方接続パッド１６１に対向させた状態で、はんだ付によって接続させる。これにより、相手方コネクタ１０１を容易に、かつ、短時間で組立てることができる。 Further, when assembling the mating connector 101, it is desirable that first, the contact portion 154 of each mating terminal 151 is inserted into the corresponding through hole 121a of the terminal holding member 121, and the contact portion 154 has a predetermined length. The tip is projected from the through hole 121a. As a result, each mating terminal 151 is provided by the terminal holding member 121 in a state where the bottom surfaces of the substrate fixing portions 152 are substantially flush with each other and the arrangement form is the same as that of the mating connection pad 161. Be retained. Then, the bottom surfaces of the board fixing portions 152 of the plurality of mating terminals 151 held by the terminal holding member 121 are connected by soldering while facing the mating connection pad 161 of the mating board 111. As a result, the mating connector 101 can be easily and quickly assembled.

次に、前記構成のコネクタ１と相手方コネクタ１０１とを嵌合させる動作について説明する。 Next, the operation of fitting the connector 1 having the above configuration and the mating connector 101 will be described.

図５は第１の実施の形態におけるコネクタと相手方コネクタとが嵌合する直前の状態を示す二面図、図６は第１の実施の形態におけるコネクタと相手方コネクタとが嵌合した状態を示す二面図、図７は第１の実施の形態における端子が相手方端子の位置ずれを吸収する動作を示す二面図である。なお、図５及び６において、（ａ）は背面図、（ｂ）は側面図であり、図７において、（ａ）は端子と相手方端子とが嵌合する第１の過程を示す図、（ｂ）は端子と相手方端子とが嵌合する第２の過程を示す図である。 FIG. 5 is a two-view view showing a state immediately before the connector and the mating connector in the first embodiment are fitted, and FIG. 6 is a state in which the connector and the mating connector in the first embodiment are fitted. Two views and FIG. 7 are two views showing an operation in which the terminal in the first embodiment absorbs the misalignment of the mating terminal. 5 and 6, FIG. 5A is a rear view, FIG. 7B is a side view, and FIG. 7A is a diagram showing a first process in which the terminal and the mating terminal are fitted to each other. b) is a diagram showing a second process in which the terminal and the mating terminal are fitted.

まず、オペレータは、図５に示されるように、コネクタ１の基板１１の表面と、相手方コネクタ１０１の相手方基板１１１の表面とを対向させた状態とし、Ｘ－Ｙ平面において、各端子５１の開口部５６の中心の位置と、対応する相手方端子１５１の接触部１５４の中心の位置とが合致すると、コネクタ１と相手コネクタ１０１とが互いに正規位置となり、コネクタ１と相手コネクタ１０１との位置合せが完了する。 First, as shown in FIG. 5, the operator sets the surface of the substrate 11 of the connector 1 and the surface of the mating substrate 111 of the mating connector 101 to face each other, and opens the terminals 51 in the XY plane. When the center position of the portion 56 and the center position of the contact portion 154 of the corresponding mating terminal 151 match, the connector 1 and the mating connector 101 are in normal positions with each other, and the connector 1 and the mating connector 101 are aligned with each other. Complete.

このような正規位置を維持しつつ、コネクタ１及び／又は相手コネクタ１０１を相手側に接近する方向、すなわち、嵌合方向に移動させると、相手コネクタ１０１の相手方端子１５１の接触部１５４がコネクタ１の端子５１の開口部５６内に進入し、さらに、前記端子５１の一対の接触腕部５４ｂ同士の間に進入する。前記一対の接触腕部５４ｂにおいて、基端部５４ｂ１同士の間隔は相手方端子１５１の接触部１５４の外寸よりも大きいが、傾斜する傾斜部５４ｂ２同士の間隔は下方に向うにつれて漸減するので、相手方端子１５１の接触部１５４は、途中で傾斜部５４ｂ２に接触する。そして、一対の接触腕部５４ｂの互いに向合う面において、傾斜部５４ｂ２と先端部５４ｂ３との接続部分は湾曲しているので、相手方端子１５１の接触部１５４が更に進行すると、接触腕部５４ｂ同士の間隔がスムーズに押広げられる。そして、主として、細長いカンチレバー状の接触腕部５４ｂが弾性的に変形して、互いに対向する先端部５４ｂ３の間隔が押広げられ、接触腕部５４ｂは、自身の発揮するばね力によって、相手方端子１５１の接触部１５４の両側に押付けられる。これにより、図１及び６に示されるように、コネクタ１と相手方コネクタ１０１との嵌合が完了すると、各端子５１と各相手方端子１５１とが導通した状態となる。 When the connector 1 and / or the mating connector 101 is moved in the direction approaching the mating side, that is, in the mating direction while maintaining such a normal position, the contact portion 154 of the mating terminal 151 of the mating connector 101 becomes the connector 1. It enters into the opening 56 of the terminal 51, and further enters between the pair of contact arm portions 54b of the terminal 51. In the pair of contact arm portions 54b, the distance between the base end portions 54b1 is larger than the outer dimension of the contact portion 154 of the other terminal 151, but the distance between the inclined inclined portions 54b2 gradually decreases as it goes downward. The contact portion 154 of the terminal 151 contacts the inclined portion 54b2 on the way. Since the connecting portion between the inclined portion 54b2 and the tip portion 54b3 is curved on the surfaces of the pair of contact arm portions 54b facing each other, when the contact portion 154 of the mating terminal 151 further progresses, the contact arm portions 54b come together. The interval is smoothly expanded. Then, mainly, the elongated cantilever-shaped contact arm portion 54b is elastically deformed, the distance between the tip portions 54b3 facing each other is expanded, and the contact arm portion 54b exerts its own spring force to cause the mating terminal 151. It is pressed on both sides of the contact portion 154 of. As a result, as shown in FIGS. 1 and 6, when the mating of the connector 1 and the mating connector 101 is completed, each terminal 51 and each mating terminal 151 are in a conductive state.

つまり、図６に示されるように、各相手方端子１５１の接触部１５４が各端子５１の一対の接触腕部５４ｂ同士の間に進入することにより、前記相手方端子１５１の接触部１５４からの力を受けて、前記一対の接触部５４の間隔が弾性的に押広げられる。これにより、前記接触腕部５４ｂがばね力を発揮するので、相手方端子１５１の接触部１５４は、基板１１の短手方向の両側から前記接触腕部５４ｂによって挟持され、該接触腕部５４ｂと確実に接触して導通する。したがって、衝撃や振動を受けたときにも、各端子５１と各相手端子１５１との導通状態を維持することができる。そして、各端子５１の基板固定部５２が接続された基板１１上の接続パッド６１に連結された導電トレースと、相手端子１５１の基板固定部１５２が接続された相手方基板１１１上の相手方接続パッド１６１に連結された導電トレースとが導通する。 That is, as shown in FIG. 6, the contact portion 154 of each partner terminal 151 enters between the pair of contact arm portions 54b of each terminal 51, so that the force from the contact portion 154 of the partner terminal 151 is applied. In response, the distance between the pair of contact portions 54 is elastically expanded. As a result, the contact arm portion 54b exerts a spring force, so that the contact portion 154 of the mating terminal 151 is sandwiched by the contact arm portions 54b from both sides in the lateral direction of the substrate 11, and is surely connected to the contact arm portion 54b. Contact and conduct. Therefore, even when it receives an impact or vibration, the conduction state between each terminal 51 and each partner terminal 151 can be maintained. Then, the conductive trace connected to the connection pad 61 on the board 11 to which the board fixing portion 52 of each terminal 51 is connected and the mating connection pad 161 on the mating board 111 to which the board fixing portion 152 of the mating terminal 151 is connected. Conductive with the conductive trace connected to.

ところで、コネクタ１及び／又は相手方コネクタ１０１の各部の寸法精度の低下や組立公差の増加、コネクタ１と相手方コネクタ１０１とを嵌合させる動作精度の低下等の何らかの原因により、いくつかの端子５１の開口部５６の中心の位置と、対応する相手方端子１５１の接触部１５４の中心の位置とがずれてしまうことがある。すなわち、端子５１に対し、相対的に、相手方端子１５１に位置ずれが生じてしまう場合がある。しかし、このような場合であっても、端子５１は、弾性変形部５３を有するので、前記相手方端子１５１の位置ずれを吸収することができる。 By the way, some terminals 51 have some causes such as a decrease in dimensional accuracy of each part of the connector 1 and / or the mating connector 101, an increase in assembly tolerance, and a decrease in operating accuracy for fitting the connector 1 and the mating connector 101. The position of the center of the opening 56 may be misaligned with the position of the center of the contact portion 154 of the corresponding mating terminal 151. That is, the position of the other terminal 151 may be displaced relative to the terminal 51. However, even in such a case, since the terminal 51 has the elastically deformed portion 53, it is possible to absorb the misalignment of the mating terminal 151.

例えば、端子５１に対し、相対的に、基板１１の短手方向（Ｙ軸方向）への位置ずれが相手方端子１５１に生じた場合、図７（ａ）に示されるように、相手方端子１５１の接触部１５４は、端子５１の開口部５６内に進入する際に、該開口部５６の中心から基板１１の短手方向（図７（ａ）に示される例においては、Ｙ軸正方向）に偏倚した状態となっている。この状態で、相手方端子１５１の接触部１５４が端子５１の一対の接触腕部５４ｂ同士の間に進入すると、図７（ｂ）に示されるように、弾性変形部５３が変形し、該弾性変形部５３の上端に接続された接触部５４及び連結部５５は、相手方端子１５１の接触部１５４と同様に、基板１１の短手方向に偏倚して、嵌合が完了する。そして、図６に示されるような端子５１の開口部５６の中心の位置と相手方端子１５１の接触部１５４の中心の位置とが合致している場合と同様に、一対の接触部５４の間隔は、相手方端子１５１の接触部１５４からの力を受けて、弾性的に押広げられる。これにより、前記接触腕部５４ｂがばね力を発揮するので、相手方端子１５１の接触部１５４は、基板１１の短手方向の両側から前記接触腕部５４ｂによって挟持され、該接触腕部５４ｂと確実に接触して導通する。したがって、衝撃や振動を受けたときにも、各端子５１と各相手端子１５１との導通状態を維持することができる。 For example, when the position shift of the substrate 11 in the lateral direction (Y-axis direction) relative to the terminal 51 occurs in the mating terminal 151, as shown in FIG. 7A, the mating terminal 151 When the contact portion 154 enters the opening 56 of the terminal 51, the contact portion 154 is directed from the center of the opening 56 in the lateral direction of the substrate 11 (in the example shown in FIG. 7A, the positive direction of the Y axis). It is in a biased state. In this state, when the contact portion 154 of the mating terminal 151 enters between the pair of contact arm portions 54b of the terminal 51, the elastically deformed portion 53 is deformed and the elastically deformed portion 53 is deformed as shown in FIG. 7B. The contact portion 54 and the connecting portion 55 connected to the upper end of the portion 53 are biased in the lateral direction of the substrate 11 in the same manner as the contact portion 154 of the mating terminal 151, and the fitting is completed. Then, as in the case where the position of the center of the opening 56 of the terminal 51 and the position of the center of the contact portion 154 of the mating terminal 151 match as shown in FIG. 6, the distance between the pair of contact portions 54 is , It is elastically expanded by receiving a force from the contact portion 154 of the mating terminal 151. As a result, the contact arm portion 54b exerts a spring force, so that the contact portion 154 of the mating terminal 151 is sandwiched by the contact arm portions 54b from both sides in the lateral direction of the substrate 11, and is surely connected to the contact arm portion 54b. Contact and conduct. Therefore, even when it receives an impact or vibration, the conduction state between each terminal 51 and each partner terminal 151 can be maintained.

つまり、端子５１と相手方端子１５１との間に位置ずれが生じた場合、接触部５４よりも、柔軟であり、弾性変形しやすい、すなわち、ばね定数の低い弾性変形部５３が、主として、変形することによって、位置ずれを吸収する。したがって、端子５１及び相手方端子１５１は、塑性変形したり、破損したりすることがなく、端子５１と接続パッド６１との接続及び相手方端子１５１と相手方接続パッド１６１との接続が破断することもない。また、接触部５４は、比較的弾性変形しにくい、すなわち、ばね定数が高いので、相手方端子１５１の接触部１５４が一対の接触部５４の間に進入し、該一対の接触部５４の間隔が押広げられると、接触腕部５４ｂが強いばね力を発揮するため、前記接触部１５４を強く挟持することができ、接触腕部５４ｂと接触部１５４との接触が確実になる。したがって、衝撃や振動を受けたときにも、各端子５１と各相手端子１５１との導通状態を維持することができる。 That is, when a positional deviation occurs between the terminal 51 and the mating terminal 151, the elastically deformed portion 53, which is more flexible and easily elastically deformed than the contact portion 54, that is, the elastically deformed portion 53 having a low spring constant is mainly deformed. By doing so, the misalignment is absorbed. Therefore, the terminal 51 and the mating terminal 151 are not plastically deformed or damaged, and the connection between the terminal 51 and the connection pad 61 and the connection between the mating terminal 151 and the mating connection pad 161 are not broken. .. Further, since the contact portion 54 is relatively hard to be elastically deformed, that is, the spring constant is high, the contact portion 154 of the mating terminal 151 enters between the pair of contact portions 54, and the distance between the pair of contact portions 54 is increased. When the contact arm portion 54b is pushed open, the contact arm portion 54b exerts a strong spring force, so that the contact portion 154 can be strongly sandwiched, and the contact between the contact arm portion 54b and the contact portion 154 is ensured. Therefore, even when it receives an impact or vibration, the conduction state between each terminal 51 and each partner terminal 151 can be maintained.

このように、本実施の形態におけるコネクタ１においては、端子５１が、一対の弾性変形部５３を有し、一対の接触部５４の各々が各弾性変形部５３に接続されているので、一対の接触部５４は、弾性変形部５３が弾性変形する方向に偏倚することができる。そのため、端子５１とは別体の樹脂等から成るハウジングを用いて相手方端子１５１の位置ずれの範囲を規制する必要がなく、嵌合時に位置ずれが生じても、接触部５４同士の位置関係が変化しないので、一対の接触腕部５４ｂが相手方端子１５１を均等な接触圧で挟持することができ、端子５１と相手方端子１５１との安定した接触状態を得ることができる。また、端子５１が、簡素な構成でありながら、位置ずれを吸収することができるので、端子５１及び相手方端子１５１は、塑性変形したり、破損したりすることがなく、端子５１と接続パッド６１との接続及び相手方端子１５１と相手方接続パッド１６１との接続が破断することもないので、基板１１と相手方基板１１１とを安定的に接続することができる。さらに、外力や衝撃を受けても、一対の弾性変形部５３が弾性変形して吸収するので、基板固定部５２に伝達されることがないので、いわゆるはんだ剥がれが生じて端子５１と接続パッド６１との接続が破断してしまうことがなく、端子５１と基板１１との導通状態が安定する。 As described above, in the connector 1 of the present embodiment, since the terminals 51 have a pair of elastically deformed portions 53 and each of the pair of contact portions 54 is connected to each elastically deformed portion 53, a pair of elastically deformed portions 53. The contact portion 54 can be biased in the direction in which the elastically deformed portion 53 is elastically deformed. Therefore, it is not necessary to regulate the range of the misalignment of the mating terminal 151 by using a housing made of a resin or the like separate from the terminal 51, and even if the misalignment occurs during mating, the positional relationship between the contact portions 54 remains. Since it does not change, the pair of contact arm portions 54b can sandwich the mating terminal 151 with an even contact pressure, and a stable contact state between the terminal 51 and the mating terminal 151 can be obtained. Further, since the terminal 51 can absorb the misalignment even though it has a simple structure, the terminal 51 and the mating terminal 151 are not plastically deformed or damaged, and the terminal 51 and the connection pad 61 are not formed. Since the connection with the other party terminal 151 and the connection between the other party terminal 151 and the other party connection pad 161 are not broken, the board 11 and the other party board 111 can be stably connected. Further, even if an external force or an impact is applied, the pair of elastically deformed portions 53 are elastically deformed and absorbed, so that they are not transmitted to the substrate fixing portion 52, so that so-called solder peeling occurs and the terminal 51 and the connection pad 61 are formed. The connection between the terminal 51 and the substrate 11 is not broken, and the conduction state between the terminal 51 and the substrate 11 is stable.

また、一対の接触部５４の各々は、各弾性変形部５３の上端に接続された基部５４ａと、該基部５４ａの下面から下方に向けて延在する接触腕部５４ｂとを含んでいる。そして、各接触腕部５４ｂは、基部５４ａの下面に上端が接続された基端部５４ｂ１と、該基端部５４ｂ１の下端に上端が接続され、下方に向うにつれて他方の接触腕部５４ｂに接近するように傾斜する傾斜部５４ｂ２と、該傾斜部５４ｂ２の下端に上端が接続され、下方に向けて延在する先端部５４ｂ３とを含んでいる。互いに向合う接触腕部５４ｂ同士の間隔（Ｙ軸方向の距離）は、下方に向うにつれて漸減して、相手方端子１５１の接触部１５４の外寸よりも小さくなり、先端部５４ｂ３において最小となる。そのため、端子５１とは別体の樹脂等から成るハウジングを用いて相手方端子１５１が相対的に進入してくる開口部分を狭くして、端子５１に対する相手方端子１５１の位置合せをしなくても、相手方端子１５１の接触部１５４が、傾斜部５４ｂ２の傾斜に沿ってスムーズに、一対の接触腕部５４ｂの間に導入されるので、端子５１及び相手方端子１５１は、塑性変形したり、破損したりすることがない。また、接触腕部５４ｂは、弾性変形部５３と重ならない位置に配設することができる。図に示される例においては、接触腕部５４ｂが弾性変形部５３の前方（Ｘ軸正方向）に位置している。これにより、該弾性変形部５３はその板厚方向（Ｙ軸方向）に変形しても、接触腕部５４ｂと干渉することがなく、スムーズに弾性変形することができる。 Further, each of the pair of contact portions 54 includes a base portion 54a connected to the upper end of each elastic deformation portion 53, and a contact arm portion 54b extending downward from the lower surface of the base portion 54a. Then, each contact arm portion 54b has an upper end connected to a base end portion 54b1 whose upper end is connected to the lower surface of the base portion 54a and an upper end connected to the lower end of the base end portion 54b1 and approaches the other contact arm portion 54b as it goes downward. It includes an inclined portion 54b2 that is inclined so as to be such, and a tip portion 54b3 whose upper end is connected to the lower end of the inclined portion 54b2 and extends downward. The distance between the contact arm portions 54b facing each other (distance in the Y-axis direction) gradually decreases toward the lower side, becomes smaller than the outer dimension of the contact portion 154 of the mating terminal 151, and becomes the minimum at the tip portion 54b3. Therefore, it is not necessary to use a housing made of a resin or the like separate from the terminal 51 to narrow the opening portion through which the mating terminal 151 relatively enters so that the mating terminal 151 is not aligned with the terminal 51. Since the contact portion 154 of the mating terminal 151 is smoothly introduced between the pair of contact arm portions 54b along the tilting portion 54b2, the terminal 51 and the mating terminal 151 may be plastically deformed or damaged. There is nothing to do. Further, the contact arm portion 54b can be arranged at a position where it does not overlap with the elastically deformed portion 53. In the example shown in the figure, the contact arm portion 54b is located in front of the elastically deformed portion 53 (in the positive direction of the X-axis). As a result, even if the elastically deformed portion 53 is deformed in the plate thickness direction (Y-axis direction), the elastically deformed portion 53 can be smoothly elastically deformed without interfering with the contact arm portion 54b.

また、一対の接触部５４を互いに連結する連結部５５は、弾性変形部５３と重ならない位置に配設された接触腕部５４ｂと更に重ならない位置に配設することができる。図に示される例においては、弾性変形部５３の前方に位置する接触腕部５４ｂの更に前方に第１連結部５５Ａが配設されている。これにより、弾性変形部５３から離れた位置において基部５４ａ同士が連結されるので、接触部５４同士の位置関係が変化しにくく、接触腕部５４ｂ同士が相手方端子１５１の接触部１５４を均等な接触圧で挟持することができ、端子５１と相手方端子１５１との安定した接触状態を得ることができる。 Further, the connecting portion 55 that connects the pair of contact portions 54 to each other can be arranged at a position that does not further overlap with the contact arm portion 54b disposed at a position that does not overlap with the elastic deformation portion 53. In the example shown in the figure, the first connecting portion 55A is arranged further in front of the contact arm portion 54b located in front of the elastic deformation portion 53. As a result, since the base portions 54a are connected to each other at a position away from the elastically deformed portion 53, the positional relationship between the contact portions 54 is unlikely to change, and the contact arm portions 54b contact the contact portion 154 of the mating terminal 151 evenly. It can be sandwiched by pressure, and a stable contact state between the terminal 51 and the mating terminal 151 can be obtained.

また、前記連結部５５は、弾性変形部５３と重なる位置に配設することができる。図に示される例においては、下面に弾性変形部５３が接続された基部５４ａの後端における上面に第２連結部５５Ｂが接続されている。これにより、実質的に、一対の弾性変形部５３の上端が連結部５５によって連結されるので、一方の弾性変形部５３の変形に他方の弾性変形部５３が追随して変形しやすくなり、端子５１と相手方端子１５１との安定した接触状態を得ることができる。 Further, the connecting portion 55 can be arranged at a position overlapping with the elastically deforming portion 53. In the example shown in the figure, the second connecting portion 55B is connected to the upper surface at the rear end of the base portion 54a to which the elastically deforming portion 53 is connected to the lower surface. As a result, since the upper ends of the pair of elastic deformation portions 53 are substantially connected by the connecting portion 55, the deformation of one elastic deformation portion 53 is followed by the deformation of the other elastic deformation portion 53, and the terminal is easily deformed. A stable contact state between the 51 and the other terminal 151 can be obtained.

また、接触腕部５４ｂの厚さ方向（Ｙ軸方向）の寸法、すなわち、板厚を、弾性変形部５３よりも厚くすることができる。これにより、嵌合の際に端子５１と相手方端子１５１との間に位置ずれが生じた場合、接触腕部５４ｂが相手方端子１５１の接触部１５４によって押されて弾性的に変形し、十分な接触圧を発揮して相手方端子１５１の接触部１５４と接触する前に、弾性変形部５３が弾性的に変形して位置ずれを吸収するので、安定した状態で電気導通を開始することができる。 Further, the dimension of the contact arm portion 54b in the thickness direction (Y-axis direction), that is, the plate thickness can be made thicker than that of the elastically deformed portion 53. As a result, when a positional shift occurs between the terminal 51 and the mating terminal 151 during mating, the contact arm portion 54b is pushed by the contact portion 154 of the mating terminal 151 and elastically deformed, resulting in sufficient contact. Since the elastically deformed portion 53 elastically deforms to absorb the misalignment before exerting pressure and coming into contact with the contact portion 154 of the mating terminal 151, electrical conduction can be started in a stable state.

また、各弾性変形部５３においては、端子５１の他の部分よりも板厚が薄い窪み部５３ａの下端に、上方に向うにつれて板厚が漸減する下側傾斜部５３ｂを形成することができる。これにより、弾性変形部５３の変形の支点となり得る箇所が補強され、過度な変形による塑性変形の発生を抑止することができる。さらに、窪み部５３ａの上端に下方に向うにつれて板厚が漸減する上側傾斜部５３ｃを形成することにより、弾性変形部５３の上端付近が接触部５４から受けた力によって塑性変形しないように、補強することができる。 Further, in each elastically deformed portion 53, a lower inclined portion 53b whose plate thickness gradually decreases toward the upper side can be formed at the lower end of the recessed portion 53a whose plate thickness is thinner than the other portions of the terminal 51. As a result, the portion that can be the fulcrum of the deformation of the elastic deformation portion 53 is reinforced, and the occurrence of plastic deformation due to excessive deformation can be suppressed. Further, by forming an upper inclined portion 53c at the upper end of the recessed portion 53a in which the plate thickness gradually decreases toward the lower side, the vicinity of the upper end of the elastic deforming portion 53 is reinforced so as not to be plastically deformed by the force received from the contact portion 54. can do.

このように、本実施の形態における端子５１は、基板１１に固定される基板固定部５２と、相手方端子１５１を挟持する一対の接触部５４と、基板固定部５２及び接触部５４に両端がそれぞれ接続された弾性変形部５３とを備え、弾性変形部５３のばね定数が接触部５４のばね定数よりも小さい。また、本実施の形態におけるコネクタ１は、相手方端子１５１と嵌合する端子５１と、端子５１が表面に接続された基板１１とを備える。そして、端子５１は、基板１１に固定される基板固定部５２と、相手方端子１５１を挟持する一対の接触部５４と、基板固定部５２及び接触部５４に両端がそれぞれ接続された弾性変形部５３とを含み、弾性変形部５３のばね定数が接触部５４のばね定数よりも小さい。 As described above, the terminal 51 in the present embodiment has a substrate fixing portion 52 fixed to the substrate 11, a pair of contact portions 54 sandwiching the mating terminal 151, and both ends of the substrate fixing portion 52 and the contact portion 54, respectively. The elastically deformed portion 53 is provided, and the spring constant of the elastically deformed portion 53 is smaller than the spring constant of the contact portion 54. Further, the connector 1 in the present embodiment includes a terminal 51 that fits with the mating terminal 151, and a substrate 11 to which the terminal 51 is connected to the surface. The terminal 51 has a substrate fixing portion 52 fixed to the substrate 11, a pair of contact portions 54 holding the mating terminal 151, and an elastic deformation portion 53 having both ends connected to the substrate fixing portion 52 and the contact portion 54, respectively. The spring constant of the elastically deformed portion 53 is smaller than the spring constant of the contact portion 54.

これにより、高いスペース効率で相手方コネクタ１０１との接続を実現することができ、小型低背でありながら、相手方端子１５１と嵌合する際に相手方端子１５１から力を受けても、端子５１が変形したり、損傷を受けることがなく、電気的接続状態を安定的に維持することができ、信頼性が向上する。また、いわゆるはんだ剥がれが生じて端子５１と接続パッド６１との接続が破断してしまうことがなく、端子５１と基板１１との導通状態が安定する。さらに、相手方端子１５１と相手方接続パッド１６１との接続が破断してしまうこともない。 As a result, the connection with the mating connector 101 can be realized with high space efficiency, and the terminal 51 is deformed even if a force is received from the mating terminal 151 when mating with the mating terminal 151, despite its small size and low profile. It is possible to maintain a stable electrical connection without being damaged or damaged, and reliability is improved. Further, so-called solder peeling does not occur and the connection between the terminal 51 and the connection pad 61 is not broken, and the conduction state between the terminal 51 and the substrate 11 is stable. Further, the connection between the other party terminal 151 and the other party connection pad 161 is not broken.

また、弾性変形部５３は、基板固定部５２及び接触部５４よりも板厚が薄い窪み部５３ａを含んでいる。さらに、各接触部５４は、弾性変形部５３の上端に接続され、基板固定部５２と平行に延在する基部５４ａと、基部５４ａの下面から下方に向けて延在する接触腕部５４ｂとを含み、各接触腕部５４ｂは、下方に向うにつれて他方の接触腕部５４ｂに接近するように傾斜する傾斜部５４ｂ２を含んでいる。さらに、各弾性変形部５３は、基板固定部５２の基端に接続され、各基部５４ａは、その基端が弾性変形部５３に接続され、各接触腕部５４ｂは、基部５４ａの基端と先端との中間位置から下方に向けて延在する。さらに、各基部５４ａは、その基端が弾性変形部５３に接続され、その先端はＵ字状の連結部５５によって他方の基部５４ａの先端と連結されている。さらに、各基部５４ａは、その基端が他のＵ字状の連結部５５によって他方の基部５４ａの基端と連結され、平面視において、一対の基部５４ａと一対の連結部５５とによって周囲を画定された開口部５６には、相手方端子１５１が進入して、端子５１と嵌合する。さらに、端子５１と接続パッド６１との接続及び相手方端子１５１と相手方接続パッド１６１との接続が破断することもない。 Further, the elastically deformed portion 53 includes a recessed portion 53a having a thinner plate thickness than the substrate fixing portion 52 and the contact portion 54. Further, each contact portion 54 is connected to the upper end of the elastically deformed portion 53, and has a base portion 54a extending in parallel with the substrate fixing portion 52 and a contact arm portion 54b extending downward from the lower surface of the base portion 54a. Each contact arm portion 54b includes an inclined portion 54b2 that inclines toward the other contact arm portion 54b as it goes downward. Further, each elastically deformed portion 53 is connected to the base end of the substrate fixing portion 52, each base portion 54a is connected to the elastically deformed portion 53, and each contact arm portion 54b is connected to the base end of the base portion 54a. It extends downward from an intermediate position with the tip. Further, the base end of each base portion 54a is connected to the elastically deformed portion 53, and the tip thereof is connected to the tip end of the other base portion 54a by the U-shaped connecting portion 55. Further, each base portion 54a has its base end connected to the base end of the other base portion 54a by another U-shaped connecting portion 55, and is surrounded by a pair of base portions 54a and a pair of connecting portions 55 in a plan view. The mating terminal 151 enters the defined opening 56 and fits into the terminal 51. Further, the connection between the terminal 51 and the connection pad 61 and the connection between the counterpart terminal 151 and the counterpart connection pad 161 are not broken.

本実施の形態において、端子５１は、図８に示されるように、一対の基板固定部５２と、一対の弾性変形部５３と、一対の接触部５４と、各接触部５４同士を連結する連結部５５とを有する。そして、前記端子５１は、概略、その幅方向（Ｙ軸方向）中心を通るＸ－Ｚ平面を対称面とした面対称となるような全体形状を有する。 In the present embodiment, as shown in FIG. 8, the terminal 51 is connected to connect a pair of substrate fixing portions 52, a pair of elastic deformation portions 53, a pair of contact portions 54, and each contact portion 54 to each other. It has a portion 55. The terminal 51 has an overall shape that is plane-symmetrical with the XX plane passing through the center in the width direction (Y-axis direction) as the plane of symmetry.

本実施の形態における接触部５４は、前記第１の実施の形態と同様である。 The contact portion 54 in the present embodiment is the same as that in the first embodiment.

本実施の形態における基板固定部５２では、第１基板固定部５２Ａと第２基板固定部５２Ｂとの間隔は、前記第１の実施の形態における第１基板固定部５２Ａと第２基板固定部５２Ｂとの間隔よりも狭くなっている。また、前記第１の実施の形態における基板固定部５２は、断面形状が上下方向（Ｚ軸方向）の寸法が横方向（Ｙ軸方向）より長い長方形である角柱状であって、横方向、すなわち、厚さ方向の寸法が弾性変形部５３の窪み部５３ａよりも大きいのに対して、本実施の実施の形態における基板固定部５２は、断面形状が上下方向の寸法が横方向より短い長方形である平板状であり、上下方向、すなわち、厚さ方向の寸法が弾性変形部５３の窪み部５３ａと同等である。 In the substrate fixing portion 52 of the present embodiment, the distance between the first substrate fixing portion 52A and the second substrate fixing portion 52B is set between the first substrate fixing portion 52A and the second substrate fixing portion 52B in the first embodiment. It is narrower than the distance between. Further, the substrate fixing portion 52 in the first embodiment has a rectangular column whose cross-sectional shape is a rectangular shape whose cross-sectional shape is longer in the vertical direction (Z-axis direction) than in the horizontal direction (Y-axis direction). That is, while the thickness direction dimension is larger than the recessed portion 53a of the elastic deformation portion 53, the substrate fixing portion 52 in the embodiment of the present embodiment has a rectangular cross-sectional shape whose vertical dimension is shorter than the horizontal direction. It has a flat plate shape, and its dimensions in the vertical direction, that is, in the thickness direction, are equivalent to those of the recessed portion 53a of the elastically deformed portion 53.

前記第１の実施の形態における弾性変形部５３は、上下方向に直線状に延在する部分であって、窪み部５３ａの下端に接続された下側傾斜部５３ｂが基板固定部５２の上面に接続されているのに対して、本実施の形態における弾性変形部５３は、下側傾斜部５３ｂを含んでおらず、窪み部５３ａは、前後方向（Ｘ軸方向）に観て、すなわち、Ｙ－Ｚ平面上において、下端近傍部が湾曲した略Ｊ字状の形状を有し、下端が基板固定部５２の側面に接続されている。 The elastically deformed portion 53 in the first embodiment is a portion extending linearly in the vertical direction, and a lower inclined portion 53b connected to the lower end of the recessed portion 53a is attached to the upper surface of the substrate fixing portion 52. Whereas the elastically deformed portion 53 in the present embodiment is connected, the elastically deformed portion 53 does not include the lower inclined portion 53b, and the recessed portion 53a is viewed in the front-rear direction (X-axis direction), that is, Y. On the −Z plane, the lower end portion has a curved substantially J-shape, and the lower end portion is connected to the side surface of the substrate fixing portion 52.

前記第１の実施の形態における連結部５５は、一対であって、各々が、接触部５４の基部５４ａの前端同士及び後端同士をそれぞれ連結するのに対して、本実施の形態における連結部５５は、単一であり、接触部５４の基部５４ａの前端同士のみを連結する。また、前記第１の実施の形態における連結部５５は、前後方向に観て、すなわち、Ｙ－Ｚ平面上において、概略Ｕ字を逆さにしたような形状となるように湾曲させたものであって、その両端が接触部５４の基部５４ａの前端及び後端における上面に接続されているのに対し、本実施の形態における連結部５５は、平面視、すなわち、Ｘ－Ｙ平面上において、概略Ｕ字のような形状となるように湾曲させたものであって、その両端が接触部５４の基部５４ａの前端面に接続されている。 The connecting portions 55 in the first embodiment are a pair, and each connects the front ends and the rear ends of the base portion 54a of the contact portion 54, respectively, whereas the connecting portions in the present embodiment are connected to each other. Reference numeral 55 is single and connects only the front ends of the base portion 54a of the contact portion 54 to each other. Further, the connecting portion 55 in the first embodiment is curved so as to be viewed in the front-rear direction, that is, on a YZ plane so as to have a substantially U-shaped inverted shape. Both ends of the contact portion 54 are connected to the upper surfaces at the front end and the rear end of the base portion 54a of the contact portion 54, whereas the connecting portion 55 in the present embodiment is generally shown in a plan view, that is, on an XY plane. It is curved so as to have a U-shaped shape, and both ends thereof are connected to the front end surface of the base portion 54a of the contact portion 54.

前記第１の実施の形態における開口部５６は、平面視において、一対の接触部５４と一対の連結部５５とによって周囲４辺を画定されているのに対し、本実施の形態における開口部５６は、平面視において、一対の接触部５４と単一の連結部５５とによって周囲４辺のうちの３辺のみが画定され、１辺は開放されている。 In the plan view, the opening 56 in the first embodiment has four peripheral sides defined by a pair of contact portions 54 and a pair of connecting portions 55, whereas the opening 56 in the present embodiment is defined. In a plan view, only three of the four peripheral sides are defined by the pair of contact portions 54 and the single connecting portion 55, and one side is open.

なお、本実施の形態における端子５１及びコネクタ１のその他の点の構成、並びに、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、説明を省略する。 Since the configuration, operation, and effect of other points of the terminal 51 and the connector 1 in the present embodiment are the same as those in the first embodiment, the description thereof will be omitted.
