Description

【０００１】
【発明の属する技術分野】
本発明は、電気コネクタのコネクタ部を電子機器の基板側に取り付ける電気コネクタの取付け部に関するものである。
【０００２】
【従来の技術】
電気コネクタの一方のコネクタ部（プラグコンタクトを有するプラグコネクタ部やレセプタクルコンタクトを有するレセプタクルコネクタ部のいずれか）を電子機器の基板（シャーシなども可）側に取り付けるには、例えば図４〜図５に示すようにして行われている。電子機器の基板側に取り付けられる電気コネクタのコネクタ部１００は、周知のように内部に必要とされる多数のコンタクト（接触子、図示省略）が配列された樹脂成形品からなる樹脂製コネクタベースブロック１１０とこれに装着させられた金属成形品からなる金属製シェル１２０からなるものが多い。
【０００３】
そして、このコネクタ部１００の長手方向（図中左右方向）の両端には、通常樹脂製コネクタベースブロック１１０からの延設部１１１と金属製シェル１２０からの延設部１２１の両方からなる取付け部１３０，１３０があって、この取付け部１３０，１３０には、図中上下方向に貫通した取付け穴１３１，１３１（図中一方省略）が設けてある。
【０００４】
これらの取付け穴１３１，１３１には、取付けネジ２１０，２１０のネジ軸２１１，２１１を、図中上方側から挿入する一方、ネジ軸２１１，２１１の先端側を電子機器の基板３００側の取付け穴３１０，３１０（図中一方省略）に嵌め込み、この基板３００の裏側に突出した先端部分に、例えばナットなどの固定具２２０，２２０を装着させて固定している。このように固定されたコネクタ部１００には、電気コネクタの相手方のコネクタ部４００が、その中央の嵌合部４１０を嵌め込むと共に、やはりその長手方向（図中左右方向）の両端に設けた取付けネジ４２０，４２０のネジ軸４２１，４２１を、コネクタ部１００側の取付けネジ２１０，２１０の上端面側に開口したネジ穴２１２，２１２（図中一方省略）に螺着させて取り付けられるようになっている。
【０００５】
【発明が解決しようとする課題】
ところが、上記構造の取付け部にあっては、次のような問題点があった。
（１）先ず、樹脂製コネクタベースブロック１１０の延設部１１１の場合、基板３００側との間に切欠き部を設けて、適当な隙間δを形成してあるため、強固な固定状態が確保し難く、相手方のコネクタ部４００の嵌め込み時や取り外し時において、大きな不規則な外力（通常軸心を合わせた方向から正確に抜き差しするだけではなく、軸心方向に対して相当大きな力でかつ揺り動かした形で抜き差しすることが多く、この外力）がコネクタ部１００に掛かると、コネクタ部１００自体が揺れたり、ガタ付き易くなるなどの問題があった。この揺動やガタ付きが生じると、取付けネジ２１０とナットなどの固定具２２０による取付け部分などにも悪影響を与え、その締め付け状態が弛み易くなるなどの懸念がある。
【０００６】
このような隙間δを設ける理由としては、樹脂製コネクタベースブロック１１０の延設部１１１をなす樹脂部分の変形を防止することが挙げられる。
一般に、コネクタ部１００を基板３００に取り付けた後、このコネクタ部１００側のコンタクトや基板３００の表面側に実装した電子部品のリード部などを基板背面側の回路パターンなどと半田付けする必要がある。このとき、基板３００を例えば加熱溶融状態の半田浴槽上を移動させる、所謂半田フロー法を採用した場合、半田浴槽側からの熱が伝達されるため、上記隙間δがないと基板３００側の取付け穴３１０，３１０と近接した部分の樹脂部分が変形し易くなるからである。この変形によって、取付けネジ２１０とナットなどの固定具２２０による取付け部分が弛むと、経時的にさらに弛みが進行して、時にはナットなどの固定具２２０が落下する懸念がある。
【０００７】
（２）また、上記のような隙間δがあると、樹脂製コネクタベースブロック１１０の延設部１１１の下面側にフリー状態の遊び部分が生じるため、上述したように、取付けネジ２１０とナットなどの固定具２２０による取付け強度も十分確保できなくなるという問題もあった。
【０００８】
（３）さらに、このような隙間δによる遊びがあると、取付けネジ２１０と基板３００側の固定具２２０との締め付けには注意が必要とされ、強く締め付け過ぎると、樹脂製コネクタベースブロック１１０の延設部１１１部分が破損したり、金属製シェル１２０の延設部１２１が折れ曲がったりする問題もあった。
【０００９】
本発明は、このような従来の問題点に鑑みなされたもので、コネクタ部の取付け部の取付け穴に用いるネジ構造に改善を施して、上記従来の問題点を解消するようにした電気コネクタの取付け部を提供せんとするものである。
【００１０】
【課題を解決するための手段】
請求項１記載の本発明は、電子機器の基板側に単一の金属製シェルを有してなる電気コネクタのコネクタ部を取り付けるにおいて、前記コネクタ部の長手方向の両端に位置する取付け部の取付け穴に、前記電気コネクタのコネクタ部に取り付けられる相手方の電気コネクタのコネクタ部側の取付けネジのネジ軸が螺着されるネジ穴を有する外ネジのネジ軸を挿入する一方、当該外ネジのネジ軸の前記電気コネクタのコネクタ部と前記電子機器の基板との間には内ネジを装着させてネジ連設体とし、当該ネジ連設体の内ネジを前記基板側に取り付けることを特徴とする電気コネクタの取付け部にある。
【００１１】
請求項２記載の本発明は、電子機器の基板側に樹脂製コネクタベースブロックとこれに装着された単一の金属製シェルとからなる電気コネクタのコネクタ部を取り付けるにおいて、前記コネクタ部の長手方向の両端に位置する取付け部を前記金属製シェルの延設部で形成すると共に、当該延設部に穿設した取付け穴に、前記電気コネクタのコネクタ部に取り付けられる相手方の電気コネクタのコネクタ部側の取付けネジのネジ軸が螺着されるネジ穴を有する外ネジのネジ軸を挿入する一方、当該外ネジのネジ軸の前記電気コネクタのコネクタ部と前記電子機器の基板との間には内ネジを装着させてネジ連設体とし、当該ネジ連設体の内ネジを前記基板側に取り付けることを特徴とする電気コネクタの取付け部にある。
【００１２】
請求項３記載の本発明は、前記ネジ連設体の基板側への取り付けを、当該基板側の取付け穴に挿入させた基板側ネジのネジ軸を前記ネジ連設体の内ネジ側に螺着させるか、或いは前記ネジ連設体の内ネジ部分を前記基板側表面の金属層部分に溶着させるか、若しくは前記ネジ連設体の内ネジ部分を前記基板側の取付け穴に挿入させて溶着させて行うことを特徴とする請求項１又は２記載の電気コネクタの取付け部にある。
【００１３】
【発明の実施の形態】
図１は、本発明に係る電気コネクタの取付け部の一例を示したものである。
本発明の電気コネクタのコネクタ部１００Ａも、基本的には上記図４のものとほぼ同様で、内部に必要とされる多数のコンタクト（接触子）が配列された樹脂成形品からなる樹脂製コネクタベースブロック１１０と、これに装着された金属成形品からなる金属製シェル１２０からなる。
【００１４】
ただし、本例では、コネクタ部１００Ａの長手方向の両端に位置する取付け部１３０，１３０（図中一方省略）にあっては、金属製シェル１２０からの延設部１２１のみで形成してある。この延設部１２１の形状は特に限定されず、図示のように天板１２１ａと一方の側板１２１ｂからなる概略Ｌ字形や、天板１２１ａの左右に側板１２１ｂ，１２１ｂを設けた概略コ字形、さらには天板１２１ａのみとすることもできる。一方、樹脂製コネクタベースブロック１１０側にあっては、取付け部１３０に対応する部分は、上から下まですべてカット（除去）し、退避した構造としてある。
【００１５】
そして、本発明の場合、取付け部１３０をなす金属製シェル１２０の延設部１２１に穿設した取付け穴１３１には、図中上方側から外ネジ５１０のネジ軸５１１を挿入する一方、このネジ軸５１１には、雌ネジ穴５２１の貫通された内ネジ５２０Ａを図中下方から装着させてネジ連設体５００とし、このネジ連設体５００の内ネジ５２０Ａの図中下端の雌ネジ穴５２１には、基板３００側の取付け穴３１０にその裏面側から挿入させた基板側ネジ３２０のネジ軸３２１を螺着させてある。なお、外ネジ５１０の上端面側には、図４の場合と同様、電気コネクタの相手方のコネクタ部の取付けネジ用のネジ穴５１２が設けてある。
【００１６】
この構造によると、コネクタ部１００Ａの取付け部１３０部分から樹脂製コネクタベースブロック１１０の樹脂部分がカットされているため、熱変形の恐れが効果的に解消される。また、取付け部１３０が金属製シェル１２０の延設部１２１のみで形成されていても、金属製シェル１２０の天板１２１ａと基板３００間に内ネジ５２０Ａがスペーサとして介在され、それぞれの端面（上下の端面）が密着して当接するため、結局外ネジ５１０と基板側ネジ３２０との間で強固な取付け状態が得られる。
【００１７】
図２は、本発明に係る電気コネクタの取付け部の他の例を示したもので、このコネクタ部１００Ｂの場合、上記図１のものとほぼ同様構造であるが、ネジ連設体５００の基板３００側への取り付け方法が異なる。この方法では、基板３００側の表面にパターン印刷形成法などによって金属層部分３３０を設け、この部分に内ネジ５２０Ｂの下端面を半田３４０などで溶着させてある。
【００１８】
この構造でも、コネクタ部１００Ｂの取付け部１３０部分から樹脂製コネクタベースブロック１１０の樹脂部分が退避され、また、金属製シェル１２０の天板１２１ａと基板３００間に内ネジ５２０Ｂがスペーサとして介在されるため、結局上記コネクタ部１００Ａと同様の効果が得られる。
【００１９】
図３は、本発明に係る電気コネクタの取付け部の他の例を示したもので、このコネクタ部１００Ｃの場合も、上記図１のものとほぼ同様構造であるが、ネジ連設体５００の基板３００側への取り付け方法が異なる。この方法では、ネジ連設体５００の内ネジ５２０Ｃの下端側に突出軸５２２を設け、この突出軸５２２を基板３００側の取付け穴３１０に挿入させると共に、この取付け穴３１０の裏面及び／又は内側にパターン印刷形成法などによって金属層部分３４０を設けて、この部分と上記突出軸５２２を半田３４０などで溶着させてある。もちろん、この突出軸５２２をネジ軸として基板３００側の取付け穴３１０から突出させ、その先端部分に、従来と同様ナットなどの固定具を装着させてもよい。
【００２０】
この構造でも、コネクタ部１００Ｃの取付け部１３０部分から樹脂製コネクタベースブロック１１０の樹脂部分が退避され、また、金属製シェル１２０の天板１２１ａと基板３００間に内ネジ５２０Ｃがスペーサとして介在されるため、結局上記コネクタ部１００Ａと同様の効果が得られる。
【００２１】
なお、上記実施の態様では、好ましい例として、コネクタ部１００Ａ〜Ｃの取付け部１３０を、金属製シェル１２０からの延設部１２１のみで形成する場合であったが、本発明では、図４に示すような樹脂製コネクタベースブロック１１０からの延設部１１１を有する構造の取付け部１３０にあっても、この延設部１１１の図中下側にネジ連設体５００の内ネジ５２０Ａ〜Ｃがスペーサとして介在されるため、大きな強度の取付け部が得られる。
【００２２】
【発明の効果】
以上の説明から明らかなように、本発明に係る電気コネクタの取付け部によると、次のような優れた効果が得られる。
【００２３】
（１）先ず、外ネジと内ネジからなるネジ連設体の構造を採用し、この内ネジ部分がスペーサ機能を有するため、大きな強度の取付け部が得られる。
【００２４】
（２）つまり、コネクタ部の取付け部が金属製シェルからの延設部のみで形成される場合でも、或いは金属製シェルからの延設部と樹脂製コネクタベースブロックからの一部に隙間を設けた延設部との併用による場合でも、スペーサ機能の内ネジ部分によって、遊びが排除され、安定した取付け構造が得られる。
【００２５】
（３）もちろん、この内ネジによる遊びの排除によって、締め付け過ぎなどをあまり気にすることなく、取り付け作業ができるため、作業性の向上も得られる。また、取り付け作業時の締め付け過ぎによって、金属製シェルの延設部が折れ曲がったり、樹脂製コネクタベースブロックの延設部が破損したりするなどの問題も根本的に解消される。
【００２６】
（４）また、コネクタ部の取付け部を金属製シェルからの延設部のみで形成した場合、その後の半田付けなどの加熱工程において、樹脂製コネクタベースブロック部分の熱変形を効果的に防止することができる。
【００２７】
（５）さらに、ネジ連設体構造において、予め幾つかの種類の内ネジを用意しておけば、外ネジが同一構造のものであっても、電子機器の基板側に対して、バラエティーに富んだ取付け方法を提供することができる。

BACKGROUND OF THE INVENTION
The present invention relates to an electrical connector attachment portion for attaching a connector portion of an electrical connector to a board side of an electronic device.
[0002]
[Prior art]
In order to attach one connector part of the electrical connector (either a plug connector part having a plug contact or a receptacle connector part having a receptacle contact) to the substrate (chassis or the like) side of an electronic device, for example, FIG. It is done as shown in As is well known, a connector portion 100 of an electrical connector attached to the board side of an electronic device is a resin connector base block made of a resin molded product in which a large number of contacts (contacts, not shown) required inside are arranged. There are many things which consist of 110 and the metal shell 120 which consists of a metal molded product with which it was mounted | worn.
[0003]
At both ends in the longitudinal direction (left and right direction in the figure) of the connector portion 100, there are usually attached portions composed of both the extending portion 111 from the resin connector base block 110 and the extending portion 121 from the metal shell 120. There are 130 and 130, and the mounting portions 130 and 130 are provided with mounting holes 131 and 131 (one omitted in the drawing) penetrating in the vertical direction in the drawing.
[0004]
The screw shafts 211 and 211 of the mounting screws 210 and 210 are inserted into the mounting holes 131 and 131 from the upper side in the figure, and the tip ends of the screw shafts 211 and 211 are mounted on the substrate 300 side of the electronic device. 310, 310 (one omitted in the figure) is fitted, and fixing tools 220, 220 such as nuts, for example, are attached and fixed to the tip portion protruding to the back side of the substrate 300. In the connector part 100 fixed in this way, the connector part 400 of the other side of the electrical connector is fitted with the fitting part 410 at the center and is also provided at both ends in the longitudinal direction (left and right direction in the figure). The screw shafts 421 and 421 of the screws 420 and 420 are attached by being screwed into screw holes 212 and 212 (one omitted in the drawing) opened on the upper end surface side of the mounting screws 210 and 210 on the connector part 100 side. ing.
[0005]
[Problems to be solved by the invention]
However, the mounting portion of the above structure has the following problems.
(1) First, in the case of the extending portion 111 of the resin connector base block 110, a notch portion is provided between the resin connector base block 110 and the appropriate gap δ is formed, so that a strong fixed state is ensured. Difficult to do so, when inserting or removing the mating connector part 400, a large irregular external force (usually not only to insert and remove accurately from the direction in which the axes are aligned, but also to swing with a considerable amount of force in the direction of the axis. When this external force is applied to the connector part 100, there is a problem that the connector part 100 itself shakes or becomes loose. If the swinging or backlash occurs, there is a concern that the mounting portion by the fixing screw 220 such as the mounting screw 210 and the nut is adversely affected, and the tightened state is likely to be loosened.
[0006]
The reason for providing such a gap δ is to prevent deformation of the resin portion forming the extending portion 111 of the resin connector base block 110.
Generally, after the connector part 100 is attached to the board 300, it is necessary to solder the contacts on the connector part 100 side, the lead parts of electronic components mounted on the surface side of the board 300, and the like to the circuit pattern on the back side of the board. . At this time, for example, when a so-called solder flow method is used in which the substrate 300 is moved over a solder bath in a heated and melted state, heat from the solder bath side is transmitted. This is because the resin portion in the vicinity of the holes 310 and 310 is easily deformed. Due to this deformation, when the mounting portion of the mounting screw 210 and the fixing tool 220 such as a nut is loosened, there is a concern that the loosening further progresses with time, and sometimes the fixing tool 220 such as a nut falls.
[0007]
(2) If there is a gap δ as described above, a free play portion is generated on the lower surface side of the extending portion 111 of the resin connector base block 110. There is also a problem that the mounting strength by the fixing tool 220 cannot be sufficiently secured.
[0008]
(3) Further, if there is such play due to the gap δ, it is necessary to be careful in tightening the mounting screw 210 and the fixing tool 220 on the substrate 300 side. There was also a problem that the extending portion 111 was damaged or the extending portion 121 of the metal shell 120 was bent.
[0009]
The present invention has been made in view of the above-described conventional problems. An electrical connector of the electrical connector in which the screw structure used in the mounting hole of the mounting part of the connector part is improved to solve the above-described conventional problems. It is intended to provide a mounting part.
[0010]

Located in the mounting part of the electrical connector.
[0011]
According to a second aspect of the present invention, in the mounting of a connector portion of an electrical connector comprising a resin connector base block and a single metal shell attached to the substrate side of the electronic device, the longitudinal direction of the connector portion The mounting portions located at both ends of the metal shell are formed by the extending portions of the metal shell, and the mounting holes formed in the extending portions are attached to the connector portion side of the mating electrical connector attached to the connector portion of the electrical connector. The screw shaft of the external screw having a screw hole into which the screw shaft of the mounting screw is screwed is inserted, while the connector portion of the electrical connector on the screw shaft of the external screw and the board of the electronic device are The electrical connector mounting portion is characterized in that a screw is connected to form a screw continuous body, and an internal screw of the screw continuous body is attached to the substrate side.
[0012]
According to the third aspect of the present invention, the screw shaft of the board-side screw inserted into the mounting hole on the board side is screwed to the inner screw side of the screw-linking body. Or the inner screw portion of the screw connecting body is welded to the metal layer portion of the surface on the substrate side, or the inner screw portion of the screw connecting body is inserted into the mounting hole on the substrate side and welded. The electrical connector mounting portion according to claim 1, wherein the electrical connector is attached.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 shows an example of a mounting portion of an electrical connector according to the present invention.
The connector portion 100A of the electrical connector of the present invention is basically the same as that shown in FIG. 4 and is a resin connector made of a resin molded product in which a large number of contacts (contacts) required inside are arranged. It comprises a base block 110 and a metal shell 120 made of a metal molded product attached thereto.
[0014]
However, in this example, the attachment portions 130 and 130 (one omitted in the figure) located at both ends in the longitudinal direction of the connector portion 100A are formed only by the extending portions 121 from the metal shell 120. The shape of the extended portion 121 is not particularly limited. As shown in the drawing, the extended portion 121 has a substantially L-shape composed of a top plate 121a and one side plate 121b, a substantially U-shape having side plates 121b and 121b on the left and right of the top plate 121a, and May be only the top plate 121a. On the other hand, on the resin connector base block 110 side, the portion corresponding to the attachment portion 130 is cut (removed) from the top to the bottom, and has a retracted structure.
[0015]
In the case of the present invention, the screw shaft 511 of the external screw 510 is inserted into the mounting hole 131 formed in the extending portion 121 of the metal shell 120 forming the mounting portion 130 from the upper side in the figure. An inner screw 520A through which the female screw hole 521 is passed is attached to the shaft 511 from the lower side in the figure to form a screw continuous body 500, and the female screw hole 521 at the lower end of the internal thread 520A of the screw continuous body 500 in the figure. In this case, the screw shaft 321 of the board-side screw 320 inserted from the back side is screwed into the mounting hole 310 on the board 300 side. In addition, the screw hole 512 for the attachment screw of the other connector part of an electrical connector is provided in the upper end surface side of the external screw 510 similarly to the case of FIG.
[0016]
According to this structure, since the resin portion of the resin connector base block 110 is cut from the attachment portion 130 portion of the connector portion 100A, the fear of thermal deformation is effectively eliminated. Even if the mounting portion 130 is formed only by the extending portion 121 of the metal shell 120, the internal screw 520A is interposed as a spacer between the top plate 121a of the metal shell 120 and the substrate 300, and each end surface (upper and lower) End face) is in intimate contact with each other, so that a firm attachment state can be obtained between the external screw 510 and the board-side screw 320 after all.
[0017]
FIG. 2 shows another example of the mounting portion of the electrical connector according to the present invention. In the case of this connector portion 100B, the structure is almost the same as that of FIG. The attachment method to the 300 side is different. In this method, a metal layer portion 330 is provided on the surface on the substrate 300 side by a pattern printing method or the like, and the lower end surface of the internal screw 520B is welded to the portion with solder 340 or the like.
[0018]
Even in this structure, the resin portion of the resin connector base block 110 is retracted from the attachment portion 130 portion of the connector portion 100B, and the internal screw 520B is interposed as a spacer between the top plate 121a of the metal shell 120 and the substrate 300. Therefore, the same effect as the connector portion 100A can be obtained after all.
[0019]
FIG. 3 shows another example of the mounting portion of the electrical connector according to the present invention, and this connector portion 100C has substantially the same structure as that of FIG. The attachment method to the substrate 300 side is different. In this method, a protruding shaft 522 is provided on the lower end side of the inner screw 520C of the screw connecting body 500, the protruding shaft 522 is inserted into the mounting hole 310 on the substrate 300 side, and the back surface and / or the inner side of the mounting hole 310 is provided. A metal layer portion 340 is provided on the substrate by a pattern printing method or the like, and this portion and the protruding shaft 522 are welded with solder 340 or the like. Of course, the protruding shaft 522 may be protruded from the mounting hole 310 on the substrate 300 side as a screw shaft, and a fixing tool such as a nut may be attached to the tip of the protruding shaft 522.
[0020]
Also in this structure, the resin portion of the resin connector base block 110 is retracted from the attachment portion 130 portion of the connector portion 100C, and the internal screw 520C is interposed as a spacer between the top plate 121a of the metal shell 120 and the substrate 300. Therefore, the same effect as the connector portion 100A can be obtained after all.
[0021]
In the above embodiment, as a preferred example, the attachment part 130 of the connector parts 100A to 100C is formed only by the extending part 121 from the metal shell 120. However, in the present invention, FIG. Even in the attachment portion 130 having a structure having the extending portion 111 from the resin connector base block 110 as shown, the internal screws 520A to 520A-C of the screw connection body 500 are located below the extending portion 111 in the drawing. Since it is interposed as a spacer, a mounting portion with high strength can be obtained.
[0022]
【The invention's effect】
As is clear from the above description, the electrical connector mounting portion according to the present invention provides the following excellent effects.
[0023]
(1) First, the structure of a screw connection body composed of an outer screw and an inner screw is adopted, and the inner screw portion has a spacer function, so that a mounting portion having a large strength can be obtained.
[0024]
(2) That is, even when the attachment portion of the connector portion is formed only by the extension portion from the metal shell, or a gap is provided between the extension portion from the metal shell and a part from the resin connector base block. Even when combined with the extended portion, play is eliminated by the inner screw portion of the spacer function, and a stable mounting structure can be obtained.
[0025]
(3) Of course, by eliminating the play with the inner screw, it is possible to perform the mounting work without worrying too much tightening or the like, so that workability can be improved. In addition, problems such as bending of the extending portion of the metal shell or breakage of the extending portion of the resin connector base block due to excessive tightening at the time of attachment work are fundamentally solved.
[0026]
(4) Further, when the attachment portion of the connector portion is formed only by the extending portion from the metal shell, the thermal deformation of the resin connector base block portion is effectively prevented in the subsequent heating process such as soldering. be able to.
[0027]
(5) Furthermore, in the screw-connected body structure, if several types of internal screws are prepared in advance, even if the external screws have the same structure, the board side of the electronic device can be varied. A rich installation method can be provided.
