【技術分野】
本発明は、ボードツーボード（ＢＯＡＲＤ ＴＯ ＢＯＡＲＤ）タイプのコネクタ装置に関する。
【０００２】
【従来技術およびその問題点】
ボードツーボードタイプのコネクタ装置は、一対の基板（ＢＯＡＲＤ）にそれぞれ、プラグコネクタ本体と、このプラグコネクタ本体と嵌合関係となるリセコネクタ本体とを固定してなっている。このプラグコネクタ本体とリセコネクタ本体はそれぞれ、それぞれの基板上のランド群に半田付けされるコンタクト群が支持されており、これらのコンタクト群がプラグコネクタ本体とリセコネクタ本体との嵌合状態で互いに導通する。
【０００３】
このコネクタ装置では、プラグコネクタ本体とリセコネクタ本体の低背化、及びコンタクト群の狭ピッチ化の要求から、嵌合離脱力が低下するという問題がある。また、コンタクト群を基板上のランド群に半田付けする際、フラックスがコンタクト群に付着して接触不良を起こすという問題があった。
【０００４】
【発明の目的】
本発明は、従来装置についての以上の問題意識に基づき、嵌合離脱力が大きく、かつフラックスのコンタクト群への付着に起因する接触不良を防止できるコネクタ装置を得ることを目的とする。
【０００５】
【発明の概要】
本発明は、プラグコネクタ本体と、このプラグコネクタ本体と嵌合関係となるリセコネクタ本体とを有し、このプラグコネクタ本体とリセコネクタ本体はそれぞれ、それぞれの基板上のランド群に半田付けされ、嵌合状態で互いに導通するコンタクト群を有し、プラグコネクタ本体は、基板に沿う底壁と、この底壁に連なりリセコネクタ本体の嵌合凹部に嵌まる挿入縦壁とを有するコネクタ装置において、プラグコネクタ本体のコンタクト群は、底壁の基板側の面に沿う半田付け脚部と、該底壁を貫通して挿入縦壁の内面に沿う、リセコネクタ本体の嵌合凹部に臨むコンタクト群と接触する立ち上がり脚部と、同挿入縦壁の先端に沿うＵ字状部とを有しており、かつ立ち上がり脚部は、プラグコネクタ本体の挿入縦壁を含む厚さがＵ字状部側ほど厚くなるようにテーパが付されていることを特徴としている。
【０００６】
プラグコネクタ本体のコンタクト群は、該プラグコネクタ本体にインサート成形して形成することが望ましい。
【０００７】
プラグコネクタ本体のコンタクト群の立ち上がり脚部の先端部には、プラグコネクタ本体とリセコネクタ本体との嵌合状態において、リセコネクタ本体のコンタクト群の先端部が係合する突起を形成することが望ましい。
【０００８】
そして、リセコネクタ本体の嵌合凹部に臨むコンタクト群には、Ｕ字状の接触脚部と、このＵ字状接触脚部の先端部を該Ｕ字状接触脚部側に曲折した逆Ｕ字状の折返部とを設け、この逆Ｕ字状折返部の先端エッジを、プラグコネクタ本体とリセコネクタ本体の嵌合状態においてプラグコネクタ側のコンタクト群の突起の下面と係合させると、プラグコネクタ側のコンタクト群の立ち上がり壁にテーパを与えた作用と相俟ち、大きな嵌合離脱力が得られる。
【０００９】
プラグコネクタ本体の挿入縦壁と該挿入縦壁に支持されているコンタクト群、及びリセコネクタ本体の嵌合凹部と該嵌合凹部に備えられているコンタクト群はそれぞれ各一対を設けて略対称形状とするのが実際的である。
【００１０】
【発明の実施形態】
以下図１ないし図３に示す実施形態に基づいて本発明を説明する。このコネクタ装置は、基板Ｂ１に固定されるプラグコネクタ１０と、別の基板Ｂ２に固定されるリセコネクタ（リセプタクルコネクタ）２０とからなっている。プラグコネクタ１０は、合成樹脂等の絶縁材料からなるプラグコネクタ本体（インシュレータ）１１と、このプラグコネクタ本体１１に保持されたコンタクト群１２とを有する。プラグコネクタ本体１１は、基板Ｂ１に沿う底壁１１ａと、この底壁１１ａに直交し全体として平面矩形をなす挿入縦壁１１ｂと、この挿入縦壁１１ｂの中心に位置する中心位置決め突条１１ｃとを備えている。挿入縦壁１１ｂは、各一対の長辺挿入縦壁１１ｂ１と短辺挿入縦壁１１ｂ２とからなり、一対の長辺挿入縦壁１１ｂ１と中心位置決め突条１１ｃとは、互いに平行に並んでいる。
【００１１】
リセコネクタ２０は、合成樹脂等の絶縁材料からなるリセコネクタ本体（インシュレータ）２１と、このリセコネクタ本体２１に保持されたコンタクト群２２とを有している。リセコネクタ本体２１は、基板Ｂ２に沿う底壁２１ａと、この底壁２１ａに直交し全体として平面矩形をなす外形縦壁２１ｂと、この外形縦壁２１ｂの中心に位置する中心縦壁２１ｃとを備えている。この外形縦壁２１ｂと中心縦壁２１ｃとの間に、プラグコネクタ１０の挿入縦壁１１ｂを受け入れる嵌合凹部２３が形成されている。外径縦壁２１ｂは、各一対の長辺外形縦壁２１ｂ１と短辺外形縦壁２１ｂ２とからなり、中心縦壁２１ｃは、プラグコネクタ本体１１の中心位置決め突条１１ｃを受け入れる位置決め凹部２１ｃ１を有している。
【００１２】
以上のプラグコネクタ１０とリセコネクタ２０は、プラグコネクタ本体１１の一対の長辺挿入縦壁１１ｂ１が、リセコネクタ本体２１の一対の長辺外形縦壁２１ｂ１と中心縦壁２１ｃとの間の嵌合凹部２３内に嵌合され、同時に中心位置決め突条１１ｃが位置決め凹部２１ｃ１に嵌合されて嵌合状態となる。
【００１３】
プラグコネクタ１０のコンタクト群１２は、長辺挿入縦壁１１ｂ１の長手方向に整列させて設けられている。各コンタクト１２は、プラグコネクタ本体１１の底壁１１ａの基板Ｂ１側の面に沿う半田付け脚部１２ａと、該底壁１１ａを貫通して長辺挿入縦壁１１ｂ１の内面に沿う立ち上がり脚部１２ｂと、長辺挿入縦壁１１ｂ１の先端に沿うＵ字状部１２ｃとを有している。挿入縦壁１１ｂ１の「内面」とは、挿入縦壁１１ｂ１の内外の二面のうち、外部に露見しない面を意味し、立ち上がり脚部１２ｂは、底壁１１ａを貫通してこの面に達している。Ｕ字状部１２ｃは、長辺挿入縦壁１１ｂ１の先端部のみに位置し、外面の基板Ｂ１側には延びていない。つまり、長辺挿入縦壁１１ｂ１の外面の半田付け脚部１２ａからの距離Ａ（図１、図２）の部分は、長辺挿入縦壁１１ｂ１が露出している。
【００１４】
また、立ち上がり脚部１２ｂは、長辺挿入縦壁１１ｂ１を含む厚さがＵ字状部１２ｃ側ほど厚くなるようにテーパが付されている。つまり、立ち上がり脚部１２ｂの内面の延長線（面）１２ｘ（図１）は、基板Ｂ１との直交線（面）に対して角度αをなしている。さらに、立ち上がり脚部１２ｂの先端部には、突起１２ｄが形成されている。
【００１５】
以上のコンタクト群１２は、プラグコネクタ本体１１にインサート成形される。圧入によりコンタクト群１２をプラグ本体１１に固定すると、圧入時にプラグコネクタ本体１１に穴が形成されてしまうのに対し、インサート成形によると、プラグコネクタ本体１１に穴（コンタクト群１２との間の隙間）が形成されることがない。このため、半田付け脚部１２ａを基板Ｂ１上のランド群１３（図１、図２）に半田付けするとき、プラグコネクタ本体１１に形成された穴を通ってよじ登り、隣接するコンタクト群１２を導通させてしまうおそれがない。また、コンタクト群１２の立ち上がり脚部１２ｂは、プラグコネクタ本体１１の底壁１１ａを貫通して長辺挿入縦壁１１ｂ１の内面に沿い、Ｕ字状部１２ｃは長辺挿入縦壁１１ｂ１の先端部のみに設けられているため、同様に半田付け時に長辺挿入縦壁１１ｂ１の外面に飛ぶフラックス（絶縁物）がＵ字状部１２ｃに付着するおそれが少なく、導通不良を生じるおそれがない。
【００１６】
リセコネクタのコンタクト群２２は、長辺外径縦壁２１ｂと嵌合凹部２３の長手方向に整列させて設けられている。各コンタクト２２は、基板Ｂ２の表面に沿う半田付け脚部２２ａと、長辺外形縦壁２１ｂ１の外面に沿って立ち上がる立ち上がり脚部２２ｂと、長辺外形縦壁２１ｂ１の先端に沿う逆Ｕ字状部２２ｃと、嵌合凹部２３内に位置するＵ字状の接触脚部２２ｄと、このＵ字状接触脚部２２ｄの先端部を該Ｕ字状接触脚部側に曲折した逆Ｕ字状の折返部２２ｅとを有している。逆Ｕ字状折返部２２ｅの先端エッジ２２ｅ’は、プラグコネクタ１０とリセコネクタ２０の嵌合状態においてコンタクト群１２の突起１２ｄの下面と係合する位置関係で形成されており、抜けに抵抗を与える。
【００１７】
以上のコンタクト群２２は、リセコネクタ本体２１に圧入され、半田付け脚部２２ａは、基板Ｂ２上のランド群２４（図１、図２）に半田付けされる。
【００１８】
上記構成の本コネクタ装置は、リセコネクタ本体２１の嵌合凹部２３内に、プラグコネクタ本体１１の一対の長辺挿入縦壁１１ｂ１を挿入すると、コンタクト群１２の立ち上がり脚部１２ｂがコンタクト群２２のＵ字状接触脚部２２ｄに導通する。すなわち、立ち上がり脚部１２ｂは、Ｕ字状接触脚部２２ｄの先端の折返部２２ｅを弾性変形させながら進入し、やがてその突起１２ｄが折返部２２ｅの先端エッジ部２２ｅ’を超えると、該エッジ部２２ｅ’が突起１２ｄ下面に係合しクリック感が得られる。また、立ち上がり脚部１２ｂは、長辺挿入縦壁１１ｂ１を含む厚さが先端部側程厚くなっているため、挿入につれて大きくなる挿入抵抗が得られる（図３参照）。
【００１９】
逆に、プラグコネクタ１０をリセコネクタ２０から離脱させるときには、立ち上がり脚部１２ｂの突起１２ｄが折返部２２ｅを押して該折返部２２ｅとＵ字状接触脚部２２ｄを一旦弾性変形させなければならない。このため、比較的大きな嵌合離脱力を得ることができる。
【００２０】
以上の説明から明らかなように、本実施形態の特徴は、第一にプラグコネクタ側のコンタクト群の形状にあり、第二にリセコネクタ側の嵌合凹部内のコンタクト群の形状にある。よって、他の部分の構成は変更してもよい。
【００２１】
【発明の効果】
以上のように本発明によれば、嵌合離脱力が大きく、かつフラックスのコンタクト群への付着に起因する接触不良を防止できるコネクタ装置を得ることができる。

[0010]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below based on the embodiment shown in FIGS. This connector device includes a plug connector 10 fixed to the board B1 and a receptacle connector (receptacle connector) 20 fixed to another board B2. The plug connector 10 includes a plug connector body (insulator) 11 made of an insulating material such as a synthetic resin, and a contact group 12 held by the plug connector body 11. The plug connector main body 11 includes a bottom wall 11a along the board B1, an insertion vertical wall 11b that is orthogonal to the bottom wall 11a and forms a planar rectangle as a whole, and a center positioning protrusion 11c positioned at the center of the insertion vertical wall 11b. It has. The insertion vertical wall 11b includes a pair of long side insertion vertical walls 11b1 and a short side insertion vertical wall 11b2, and the pair of long side insertion vertical walls 11b1 and the center positioning protrusion 11c are arranged in parallel to each other.
[0011]
The receptacle connector 20 includes a receptacle connector body (insulator) 21 made of an insulating material such as synthetic resin, and a contact group 22 held by the receptacle connector body 21. The receptacle connector main body 21 includes a bottom wall 21a along the board B2, an external vertical wall 21b that is orthogonal to the bottom wall 21a and forms a planar rectangle as a whole, and a central vertical wall 21c positioned at the center of the external vertical wall 21b. I have. A fitting recess 23 for receiving the insertion vertical wall 11b of the plug connector 10 is formed between the outer vertical wall 21b and the central vertical wall 21c. The outer diameter vertical wall 21b includes a pair of long-side outer shape vertical walls 21b1 and short-side outer shape vertical walls 21b2, and the center vertical wall 21c has a positioning recess 21c1 that receives the center positioning protrusion 11c of the plug connector body 11. are doing.
[0012]
In the plug connector 10 and the receptacle connector 20 described above, the pair of long side insertion vertical walls 11b1 of the plug connector body 11 is fitted between the pair of long side outer shape vertical walls 21b1 and the center vertical wall 21c of the receptacle connector body 21. At the same time, the center positioning protrusion 11c is fitted into the positioning recess 21c1 to be fitted into the recess 23.
[0013]
The contact group 12 of the plug connector 10 is provided so as to be aligned in the longitudinal direction of the long side insertion vertical wall 11b1. Each contact 12 includes a soldering leg portion 12a along the surface of the bottom wall 11a of the plug connector main body 11 on the board B1 side, and a rising leg portion 12b passing through the bottom wall 11a and along the inner surface of the long side insertion vertical wall 11b1. And a U-shaped portion 12c along the tip of the long side insertion vertical wall 11b1. The “inner surface” of the insertion vertical wall 11b1 means a surface that is not exposed to the outside of the inner and outer surfaces of the insertion vertical wall 11b1, and the rising leg 12b penetrates the bottom wall 11a and reaches this surface. Yes. The U-shaped portion 12c is located only at the distal end portion of the long side insertion vertical wall 11b1, and does not extend to the substrate B1 side of the outer surface. That is, the long side insertion vertical wall 11b1 is exposed at a portion of the distance A (FIGS. 1 and 2) from the soldering leg portion 12a on the outer surface of the long side insertion vertical wall 11b1.
[0014]
The rising leg 12b is tapered so that the thickness including the long side insertion vertical wall 11b1 becomes thicker toward the U-shaped portion 12c. That is, the extension line (surface) 12x (FIG. 1) of the inner surface of the rising leg portion 12b forms an angle α with the orthogonal line (surface) to the substrate B1. Further, a protrusion 12d is formed at the tip of the rising leg 12b.
[0015]
The above contact group 12 is insert-molded in the plug connector body 11. When the contact group 12 is fixed to the plug body 11 by press-fitting, a hole is formed in the plug connector body 11 at the time of press-fitting, whereas according to insert molding, a hole (gap between the contact group 12 is formed in the plug connector body 11). ) Is not formed. For this reason, when the soldering leg 12a is soldered to the land group 13 (FIGS. 1 and 2) on the board B1, it climbs through the hole formed in the plug connector main body 11, and makes the adjacent contact group 12 conductive. There is no fear of letting it go. Further, the rising leg 12b of the contact group 12 penetrates the bottom wall 11a of the plug connector body 11 along the inner surface of the long side insertion vertical wall 11b1, and the U-shaped portion 12c is the tip of the long side insertion vertical wall 11b1. Similarly, the flux (insulator) flying to the outer surface of the long side insertion vertical wall 11b1 during soldering is less likely to adhere to the U-shaped portion 12c, and there is no possibility of poor conduction.
[0016]
The contact group 22 of the receptacle connector is provided in alignment with the longitudinal direction of the long side outer diameter vertical wall 21 b and the fitting recess 23. Each contact 22 has a soldering leg portion 22a along the surface of the substrate B2, a rising leg portion 22b rising along the outer surface of the long side outer shape vertical wall 21b1, and an inverted U shape along the tip of the long side outer shape vertical wall 21b1. A portion 22c, a U-shaped contact leg portion 22d located in the fitting recess 23, and an inverted U-shaped portion obtained by bending the tip of the U-shaped contact leg portion 22d toward the U-shaped contact leg portion. And a turn-back portion 22e. The tip edge 22e ′ of the inverted U-shaped folded portion 22e is formed in a positional relationship that engages with the lower surface of the protrusion 12d of the contact group 12 when the plug connector 10 and the receptacle connector 20 are in a fitted state, and resists disconnection. give.
[0017]
The above contact group 22 is press-fitted into the receptacle connector body 21, and the soldering leg 22a is soldered to the land group 24 (FIGS. 1 and 2) on the substrate B2.
[0018]
In the connector device configured as described above, when the pair of long side insertion vertical walls 11b1 of the plug connector main body 11 are inserted into the fitting recesses 23 of the receptacle connector main body 21, the rising legs 12b of the contact group 12 It conducts to the U-shaped contact leg 22d. That is, the rising leg 12b enters while elastically deforming the folded portion 22e at the tip of the U-shaped contact leg 22d, and when the protrusion 12d eventually exceeds the tip edge portion 22e 'of the folded portion 22e, the edge portion 22e 'engages with the lower surface of the protrusion 12d, and a click feeling is obtained. Further, since the rising leg 12b includes the long side insertion vertical wall 11b1 and is thicker toward the distal end portion, an insertion resistance that increases with insertion can be obtained (see FIG. 3).
[0019]
On the other hand, when the plug connector 10 is detached from the receptacle connector 20, the protrusion 12d of the rising leg portion 12b has to push the folded portion 22e to temporarily deform the folded portion 22e and the U-shaped contact leg portion 22d. For this reason, a relatively large fitting / removing force can be obtained.
[0020]
As is clear from the above description, the feature of this embodiment is firstly in the shape of the contact group on the plug connector side, and secondly in the shape of the contact group in the fitting recess on the side of the receptacle connector. Therefore, you may change the structure of another part.
[0021]
【The invention's effect】
As described above, according to the present invention, it is possible to obtain a connector device that has a large fitting / detaching force and can prevent contact failure due to adhesion of flux to the contact group.
