Description

【0001】
【発明の属する技術分野】
本発明は、多数個の端子を列設した絶縁材料のボディに、板金よりなる環状の金属シェルを嵌装した多極型コネクタに関するものである。
【0002】
【従来の技術】
一般にこの種の多極型コネクタは、図7に示すように、多数個の端子3を列設した合成樹脂製のボディ1を備え、端子3において相手側部材と電気的に接続されるコンタクト部3a(図6(b)参照)が並ぶ部位の周囲を囲む形で環状に形成した図8のような形状の金属シェル2がボディ1に嵌装されている。金属シェル2は端子3への外来雑音の混入やコンタクト部3aから外部への輻射雑音を抑制するシールドとして設けられている。
【0003】
図示例では、図6のように、ボディ1の側面のうち端子3が並ぶ方向(長手方向)に沿った2側面に各一対の嵌合突起14が突設され、環状に形成した金属シェル2に設けた嵌合孔21が嵌合突起14に嵌合することによって、ボディ1に金属シェル2が結合されている。
【0004】
【発明が解決しようとする課題】
ところで、金属シェル2は帯状の板金により角筒状に形成され、ボディ1の長手方向の中央付近において板金の端縁が突き合わされている。図示する多極型コネクタは、回路基板への実装時に、板金の端縁が突き合わされている突き合わせ部22の近傍をボディ1と回路基板との間に挟み込むように構成されており、回路基板に実装した状態では、金属シェル2に外力が作用しても突き合わせ部22が開くことはなく、金属シェル2が変形することもない。しかしながら、突き合わせ部22の近傍には板金が厚み方向においてボディ1から離れる向きに撓むのを規制する手段が設けられていないものであるから、回路基板に実装していない状態で金属シェル2に外力が作用すると、図6(b)に二点鎖線で示すように突き合わせ部22の近傍が撓むことがある。つまり、突き合わせ部22が開くことによってシールドとしての機能が低下することがあり、また、金属シェル2が変形するとボディ1から外れることもある。とくに、端子3の個数が多くなるとボディ1の長手方向の寸法が大きくなるから、金属シェル2が一層撓みやすくなる可能性がある。
【0005】
これに対して、特開平10−241793号公報には、金属シェルを形成する板金の端部を重ね合わせるとともに、重なっている部分を凹凸係合させることによって、外力による金属シェルの変形を防止するようにしたものが開示されている。このような構成を採用すれば、外力による金属シェルの変形を防止することができるものの、図8に示した金属シェル2と比較すると重ね合わせる部分を設けた分だけ材料が増加し、また重ね合わせる部位の肉厚を他の部位よりも小さくするとともに凹凸係合させる形状に加工しなければならないから、コスト高につながるという問題が生じる。
【0006】
本発明は上記事由に鑑みて為されたものであり、その目的は、外力による金属シェルの変形を防止しながらも製造コストの増加を抑制した多極型コネクタを提供することにある。
【0007】
【課題を解決するための手段】
請求項1の発明は、多数個の端子が列設され端子の並ぶ方向に長い形状であるボディと、板金により筒状に形成され端子を配列した部位を囲む形でボディに嵌装された金属シェルとを備え、金属シェルを形成する板金の端縁の突き合わせ部は金属シェルの長手方向の一端側の側壁に形成されており、金属シェルには突き合わせ部において端縁の境界線の両側に跨る突出部が形成され、ボディには前記突出部と嵌合する凹所が形成されており、前記突出部は、前記境界線の一端側で金属シェルの長手方向の一端の側壁に沿って突出する突片と、前記境界線の他端側で金属シェルの前記側壁から外側に突設され金属シェルの側壁と併せて略U形に形成される保持片とであって、前記凹所は、前記突片が挿入されるようにボディに形成された固定穴と、前記保持片が嵌合するようにボディの外側面に形成された保持溝であることを特徴とするものである。この構成によれば、板金の端縁の突き合わせ部に端縁の境界線の両側に跨る形で突出部を設け、突出部をボディの凹所に嵌合させているから、端縁の境界線の一部が凹所に挿入されることによって分離されなくなり、外力によって金属シェルが変形するのを防止することができる。しかも、板金を重ね合わせるのではなく突出部を設けているだけであるから、金属シェルの加工が容易であるとともに材料コストの増加を抑制することができる。
【0008】
しかも、金属シェルの長手方向の中間部に突き合わせ部を設ける場合に比較すると、外力に対して撓みにくい部位に突き合わせ部を設けたことになり、金属シェルの外力による変形を抑制することができる。
【0009】
さらに、金属シェルの突き合わせ部に形成される境界線の両端部をボディに嵌合させるから、境界線が開くのを一層確実に防止することができる。
【0010】
請求項2の発明は、請求項1の発明において、前記金属シェルの長手方向の他端の側壁において前記突片および前記保持片と対称となるようにそれぞれ設けられた第2の突片および第2の保持片を備え、前記ボディには第2の突片が挿入される第2の固定穴および第2の保持片が嵌合する第2の保持溝が形成されているものである。この構成によれば、金属シェルの長手方向の両端をボディに固定するから、ボディと金属シェルとの結合強度が高くなる。
【0011】
請求項3の発明は、請求項1または請求項2の発明において、前記金属シェルの長手方向の両端部に、端子の並ぶ方向に直交する面内で相手側部材の挿抜方向に直交する方向に突出し、端子を実装する回路基板に挿入される取付片が突設されているものである。この構成によれば、回路基板に挿入される取付片を金属シェルに設けていることによって、取付片を回路基板に固定すれば回路基板への取付強度が大きくなり、相手側部材の挿抜の際に作用する力で回路基板から浮き上がるのを防止することができる。
【0012】
請求項4の発明は、請求項1ないし請求項3の発明において、前記ボディの側面に嵌合突起が突設されるとともに係止凹所が形成され、前記金属シェルには嵌合突起に嵌合する嵌合孔と係止凹所に係止される係止爪片とが形成されているものである。この構成によれば、ボディと金属シェルとの結合箇所がより多くなり、ボディと金属シェルとの結合強度が大きくなる。
【0013】
【発明の実施の形態】
本実施形態の多極型コネクタは、図1に示すように、多数個の端子3を列設した合成樹脂製のボディ1に、環状に形成した金属シェル2を嵌装した構成を有する。ここに、本実施形態では相手側部材の一部挿入される雌側コネクタを例示する。
【0014】
ボディ1は、図2に示すように、細長直方体状の主片10を有し、主片10の一面(図2の下面)には長手方向の両端部を残して突台11が突設されている。また、主片10において突台11よりも外側の両端部には突台11とは反対向きに脚片12が突設され、さらに脚片12よりも外側には突台11と同じ向きに保持片13が突設されている。主片10の短手方向の両側面には各一対の嵌合突起14が突設され、突台11の先端面には突台11の長手方向の略全長に亘る挿入凹所15(図1(b)参照)が開口する。
【0015】
脚片12と保持片13と境界部位には、主片10の短手方向の両側面と突台11側とに開放された位置決め溝16が形成され、位置決め溝16の底面中間部には固定穴17が形成される。また、各位置決め溝16の近傍には主片10の短手方向の両面を凹没させた係止凹所18が形成されている。係止凹所18は脚片12に対して図2の上側が凹没した段差を有している。さらに、保持片13の先端部における主片10の短手方向の中間部には、保持片13の先端面から保持片13の外側面に跨る部位で保持溝19が形成されている。
【0016】
端子3は主片10の長手方向に列設されているのであって、突台11の先端面に開口する挿入凹所15の内部で挿入凹所15の短手方向における一面側に配列されたコンタクト部3aと、各コンタクト部3aと連続一体であって主片10と両脚片12とに囲まれた部位に配列され回路基板に実装されるリード部3bとを備える。
【0017】
ところで、ボディ1の外周を囲むようにボディ1に嵌装される金属シェル2は帯状の板金により図3に示すような角筒状に形成される。ただし、リード部3bが配列されている部位、つまり主片10と両脚片12とに囲まれた部位は金属シェル2から露出する。この金属シェル2は、従来構成と同様に、ボディ1に設けた嵌合突起14に嵌合する嵌合孔21を備える。また、板金の端縁は、図3に示すように、金属シェル2の長手方向の一端の側壁で突き合わされる。つまり、この部位に突き合わせ部22が形成される。
金属シェル2の長手方向の両側壁の一部はボディ1に設けた位置決め溝16に挿入され、位置決め溝16に挿入される部位には固定穴17に挿入される突片23が突設されている。さらに、金属シェル2の長手方向の両側壁にはそれぞれ略L字形の保持片24が延設され、保持片24は金属シェル2の側壁と併せて略U形に形成されることになる。図4のように保持片24はボディ1に設けた保持溝19に挿入される。つまり、金属シェル2の突き合わせ部22は、固定穴17および保持溝19に挿入されることによって開かないように保持されることになる。
【0018】
金属シェル2には、ボディ1の脚片12に沿うように形成された延長片25が設けられており、延長片25の一部には切り起こすことにより形成され係止凹所18に係合する係止爪片26が設けられる。つまり、嵌合突起14と嵌合孔21とに加えて係止爪片26が係止凹所18に係合するから、金属シェル2はボディ1に対して突台11の突出方向には移動しないことになる。
【0019】
ところで、金属シェル2の長手方向の両端部には金属シェル2の短手方向の一面側に突出する一対の取付片27が突設されている、取付片27は、図5のように、金属シェル2の短手方向の一面を印刷配線基板よりなる回路基板4に密着させたときに、回路基板4に挿入されるように寸法が設定されており、回路基板4に設けた接地パターンに取付片27を半田5により固定すれば、金属シェル2を接地することができるとともに、回路基板4に対して金属シェル2が2箇所で固定され、結合強度が高くなる。つまり、挿入凹所15に着脱される相手側部材を抜き差しする際に金属シェル2に外力が作用しても、金属シェル2が浮き上がることがないのである。
【0020】
金属シェル2の突き合わせ部22では、図2(d)、図5のように、板金の一方の端縁に突片23と保持片24との半分を設け、他方の端縁に突片23と保持片24との半分のほかに取付片27を設けてあり、突き合わせ部22の境界線Pは2分された非直線になっている。
【0021】
上述した構成によって、金属シェル2の長手方向の中間部がボディ1に対して結合されるとともに、金属シェル2の長手方向の両端部がボディ1に対してそれぞれ3箇所で結合されるから、金属シェル2をボディ1に対して強固に結合することができる。また、板金よりなる金属シェル2に形成される突き合わせ部22は、突片23が固定穴17に挿入され、かつ保持片24が保持溝19に挿入されることによって、開かないように位置規制されるから、外力が作用しても金属シェル2が変形しないのである。
【0022】
本実施形態における金属シェル2では、短手方向の一方の側壁(回路基板4とは反対側になる側壁)に長手方向の略全長に亘る打出リブ28を2本形成してある。打出リブ28は金属シェル2から突台11に近付く向きに突設されており、金属シェル2の長手方向の寸法が比較的大きい場合でも打出リブ28によって金属シェル2の撓みを抑制することができる。
【0023】
【発明の効果】
請求項1の発明の構成によれば、板金の端縁の突き合わせ部に端縁の境界線の両側に跨る形で突出部を設け、突出部をボディの凹所に嵌合させているから、端縁の境界線の一部が凹所に挿入されることによって分離されなくなり、外力によって金属シェルが変形するのを防止することができるという利点がある。しかも、板金を重ね合わせるのではなく突出部を設けているだけであるから、金属シェルの加工が容易であるとともに材料コストの増加を抑制することができるという利点がある。
【0024】
しかも、金属シェルの長手方向の中間部に突き合わせ部を設ける場合に比較すると、外力に対して撓みにくい部位に突き合わせ部を設けたことになり、金属シェルの外力による変形をより一層抑制することができるという利点がある。
【0025】
さらに、金属シェルの突き合わせ部に形成される境界線の両端部をボディに嵌合させるから、境界線が開くのを一層確実に防止することができるという利点がある。
【0026】
請求項2の発明は、請求項1の発明において、前記金属シェルの長手方向の他端の側壁において前記突片および前記保持片と対称となるようにそれぞれ設けられた第2の突片および第2の保持片を備え、前記ボディには第2の突片が挿入される第2の固定穴および第2の保持片が嵌合する第2の保持溝が形成されているものであり、金属シェルの長手方向の両端をボディに固定するから、ボディと金属シェルとの結合強度が高くなるという利点がある。
【0027】
請求項3の発明は、請求項1または請求項2の発明において、前記金属シェルの長手方向の両端部に、端子の並ぶ方向に直交する面内で相手側部材の挿抜方向に直交する方向に突出し、端子を実装する回路基板に挿入される取付片が突設されているものであり、回路基板に挿入される取付片を金属シェルに設けていることによって、取付片を回路基板に固定すれば回路基板への取付強度が大きくなり、相手側部材の挿抜の際に作用する力で回路基板から浮き上がるのを防止することができるという利点がある。
【0028】
請求項4の発明は、請求項1ないし請求項3の発明において、前記ボディの側面に嵌合突起が突設されるとともに係止凹所が形成され、前記金属シェルには嵌合突起に嵌合する嵌合孔と係止凹所に係止される係止爪片とが形成されているものであり、ボディと金属シェルとの結合箇所がより多くなり、ボディと金属シェルとの結合強度が大きくなるという利点がある。

BACKGROUND OF THE INVENTION
The present invention relates to a multipolar connector in which an annular metal shell made of sheet metal is fitted to a body of an insulating material in which a large number of terminals are arranged.
[0002]
[Prior art]
As shown in FIG. 7, this type of multipolar connector generally includes a synthetic resin body 1 in which a large number of terminals 3 are arranged, and a contact portion electrically connected to a mating member at the terminal 3. A metal shell 2 having a shape as shown in FIG. 8 formed in an annular shape so as to surround the periphery of portions where 3 a (see FIG. 6B) are arranged is fitted to the body 1. The metal shell 2 is provided as a shield for suppressing external noise from entering the terminal 3 and radiation noise from the contact portion 3a to the outside.
[0003]
In the illustrated example, as shown in FIG. 6, a pair of fitting projections 14 project from two side surfaces along the direction (longitudinal direction) in which the terminals 3 are arranged on the side surface of the body 1 to form an annular metal shell 2. The metal shell 2 is coupled to the body 1 by fitting the fitting hole 21 provided in the fitting hole 14 into the fitting protrusion 14.
[0004]
[Problems to be solved by the invention]
By the way, the metal shell 2 is formed in a rectangular tube shape by a strip-shaped sheet metal, and the edge of the sheet metal is abutted in the vicinity of the center of the body 1 in the longitudinal direction. The illustrated multipolar connector is configured such that when mounted on a circuit board, the vicinity of the abutting portion 22 where the edge of the sheet metal is abutted is sandwiched between the body 1 and the circuit board. In the mounted state, even if an external force is applied to the metal shell 2, the butted portion 22 does not open, and the metal shell 2 is not deformed. However, since there is no means for restricting the sheet metal from being bent in the direction away from the body 1 in the thickness direction in the vicinity of the butting portion 22, the metal shell 2 is not mounted on the circuit board. When an external force is applied, the vicinity of the butting portion 22 may bend as shown by a two-dot chain line in FIG. That is, the function as a shield may be lowered by opening the butting portion 22, and may be detached from the body 1 when the metal shell 2 is deformed. In particular, when the number of terminals 3 increases, the dimension in the longitudinal direction of the body 1 increases, so that the metal shell 2 may be more easily bent.
[0005]
On the other hand, Japanese Patent Laid-Open No. 10-241793 prevents the deformation of the metal shell due to an external force by overlapping the end portions of the sheet metal forming the metal shell and engaging the overlapping portions with irregularities. What has been made is disclosed. If such a configuration is adopted, the deformation of the metal shell due to external force can be prevented, but the material is increased by an amount corresponding to the overlapping portion as compared with the metal shell 2 shown in FIG. Since the thickness of the part must be made smaller than the other parts and processed into a concavo-convex engagement, the problem of high costs arises.
[0006]
The present invention has been made in view of the above reasons, and an object of the present invention is to provide a multipolar connector that suppresses an increase in manufacturing cost while preventing deformation of the metal shell due to external force.
[0007]
[Means for Solving the Problems]
According to the first aspect of the present invention, there is provided a body having a large number of terminals arranged in a row and extending in a direction in which the terminals are arranged, and a metal fitted into the body so as to surround a portion where the terminals are arranged in a cylindrical shape by sheet metal. and a shell, butted portion of the edge of the sheet metal forming the metal shell is formed in a side wall of one longitudinal end of the metal shell, spans both sides of the edge of the boundary line in the butt portion is a metal shell A protrusion is formed, and a recess is formed in the body so as to fit with the protrusion.

According to this configuration, since the protruding portion is provided in the shape of the edge of the sheet metal so as to straddle both sides of the boundary of the edge, the protruding portion is fitted in the recess of the body. A part of the metal shell is not separated by being inserted into the recess, and the metal shell can be prevented from being deformed by an external force. In addition, the metal shells are easily processed and the increase in material cost can be suppressed because the protruding portions are provided instead of overlapping the metal plates.
[0008]
Moreover, when compared to the case where the longitudinal direction of the intermediate portion to the abutted portion of the metal shell, will be provided with a butt portion hardly site deflection against an external force, it is possible to win suppress the deformation of the metal shell by an external force .
[0009]
Furthermore, since both ends of the boundary line formed at the butt portion of the metal shell are fitted to the body, it is possible to prevent the boundary line from opening more reliably.
[0010]

And a second holding hole into which the second protruding piece is inserted and a second holding groove into which the second holding piece is fitted. According to this configuration, since both ends of the metal shell in the longitudinal direction are fixed to the body, the bonding strength between the body and the metal shell is increased.
[0011]
According to a third aspect of the present invention, in the first or second aspect of the present invention, the longitudinal direction of the metal shell is perpendicular to the insertion / extraction direction of the mating member within a plane perpendicular to the terminal arrangement direction. A mounting piece that protrudes and is inserted into a circuit board on which a terminal is mounted is provided. According to this configuration, since the mounting piece to be inserted into the circuit board is provided on the metal shell, if the mounting piece is fixed to the circuit board, the mounting strength to the circuit board is increased, and the mating member is inserted and removed. It is possible to prevent floating from the circuit board due to the force acting on the circuit board.
[0012]
According to a fourth aspect of the present invention, in the first to third aspects of the present invention, a fitting projection projects from the side surface of the body and a locking recess is formed, and the metal shell is fitted into the fitting projection. A mating hole and a locking claw piece locked in the locking recess are formed. According to this configuration, the number of joints between the body and the metal shell is increased, and the joint strength between the body and the metal shell is increased.
[0013]
