Description

【０００１】
【発明の属する技術分野】
本発明は、オス型コネクタの導電体シールドと、メス型コネクタの導電体シールドとを接続する接触片を備えたコネクタのシールド接続装置に関する。
【０００２】
【従来の技術】
メモリー等のＩＣが内蔵されたカードが挿抜されるカード用コネクタやケーブルコネクタには、導電体シールドが設けられている。この導電体シールドは、カード用コネクタの場合、静電気による回路破壊防止等の目的で設けられる。ケーブルコネクタの場合、導電体シールドは電気的ノイズやクロストーク等を防止する目的で設けられる。
【０００３】
このように、導電体シールドは、オス型コネクタ及びメス型コネクタの双方に設けられ、両コネクタの結合時に接触して電気的に接続される。その際、導電体シールド同士の電気的接続が確実に行われるように、一方の導電体シールド側に接触片が設けられることが多い。
【０００４】
図５〜図８には、ＩＣカード（オス型コネクタ）を挿入するメス型コネクタ３００側に接触片を設けたカード用コネクタの従来例が示されている。このメス型コネクタ３００は、図５に示すように導電性の金属シェル３０１を備えている。金属シェル３０１には、ＩＣカード３１０を挿入するための挿入口３０２が設けられている。したがって、導電体シールドはこの金属シェル３０１により形成されている。
【０００５】
金属シェル３０１は、表裏の面板部分（一方の面板部分のみ図示）３０３と、両側の側板部分３０４、３０５とを有する内部中空に形成されている。そして、両側の側板部分３０４，３０５に接触片３０６，３０７が設けられている。金属シェル３０１は、通常、金属板の加工により形成される。したがって、接触片３０６，３０７は、側板部分３０４，３０５からの切り起こし片によって形成されている。
【０００６】
ＩＣカード３１０は、その表面が同じく導電体シールドを形成する金属シェルにより覆われていている。ＩＣカード３１０の挿入部の先端３１１には、メス型コネクタ３００の例えばピンコンタクトに接続されるソケットコンタクト等（何れも図示せず）が設けられている。
【０００７】
ＩＣカード３１０をメス型コネクタ３００に挿入すると、その挿入過程において接触片３０６，３０７がＩＣカード３１０の側面３１２、３１３に接触し、導電体シールド同士が電気的に接続される（図６及び図７参照）。
【０００８】
【発明が解決しようとする課題】
このような従来のカード用コネクタにおいては、接触片３０６，３０７が変形する問題があった。即ち、接触片３０６，３０７は図示のように挿入口３０２の口部近くに設けられている。そのため、ＩＣカード３１０の挿入初期において、図８に示すようにＩＣカード３１０を斜めに挿入した場合、一方の接触片３０６が外側へ押し出されて変形することがあった。
【０００９】
この接触片３０６の変形は、その基端部３０８の塑性変形となり、元の状態に復帰しなくなる。その結果、接触片を介した導電体シールド同士の電気的接続の信頼性が低下する問題が生じる。ＩＣカード３１０が接触片３０７方向へ向いて斜めに挿入された場合、接触片３０７の基端部３０９が塑性変形する。
【００１０】
こうした問題は、特にユーザがＩＣカード３１０の挿入操作時に「こじる」ような操作を行うことが多々あることに起因している。また、接触片の塑性変形が大きくなる原因について考察したところ、図８においてＩＣカード３１０の先端コーナ部分３１５が接触片３０６の基端部３０８の近くに当たるほど顕著になることも判った。
【００１１】
なお、これらの問題は、カード用コネクタに限らず、導電体シールドを備えたケーブルコネクタにおいても同様に発生する。
【００１２】
よって、本発明の課題は、接触片の塑性変形を防止して、導電体シールド同士の電気的接続の信頼性向上を図ることができるコネクタのシールド接続装置を提供することにある。
【００１３】
【課題を解決するための手段】
本発明に係るコネクタのシールド接続装置は、オス型コネクタの導電体シールドと、メス型コネクタの導電体シールドとを接続する接触片を備え、メス型コネクタは、オス型コネクタの挿入口を備え、接触片は、挿入口の内壁から挿入口内に突出してオス型コネクタの導電体シールドに接触する接点部と、挿入口の内壁よりも外側へ湾曲した湾曲部とを備え、湾曲部は、接触片の基端部と接点部との間に位置し、基端部は湾曲部よりも挿入口の入口側に位置している構成とした。
【００１４】
本発明によれば、接触片は、挿入口近くの内壁よりも外側へ湾曲した湾曲部を備え、この湾曲部は接点部よりも挿入口の入口側へ位置している。そのため、オス型コネクタが斜めに挿入されても、挿入初期には湾曲部に接触せず、まず接点部に接触する。接点部は基端部から湾曲部が存在する分だけ離れているので、接触片の基端部に大きな応力が作用しない。これにより接触片の変形を防止することができる。
【００１５】
前記接触片の湾曲部は、オス型コネクタの挿入部先端のコーナ部分が挿入口の内壁よりも外側へ進入するのを許容する曲率に設定されていることが望ましい。このようにすれば、オス型コネクタを斜めに挿しても、その挿入部先端のコーナ部分を湾曲部が許容するので、接触片の基端部に大きな応力が作用しないようにすることができる。即ち、湾曲部はコーナ部分が接触片側へ進入してきても、これを逃がす作用を発揮する。
【００１６】
前記接触片の湾曲部は、接触片の基端部から挿入口の内壁よりも外側に向かって延びる第１斜辺部と、その第１斜辺部からの折り返し部を介して接点部に至る第２斜辺部とを有し、その第２斜辺部は、折り返し部から接点部に向かうに従って挿入口の奥に向かって延びる斜辺として形成されていることが望ましい。このように構成すれば、基端部から延びる第１斜辺部にオス型コネクタの先端コーナ部分が強く接触しないようにすることができる。また、第２斜辺部はオス型コネクタの先端コーナ部分のガイド斜面として作用し、接点部をオス型コネクタの導電体シールドに対して円滑に接触させる機能を発揮する。
【００１７】
前記メス型コネクタは、挿入口が形成された導電性の金属シェルを備え、その金属シェルに接触片が設けられていることが望ましい。接触片を金属シェルに直接設けた場合、別部材とするのに比べて部品点数の削減、製作性の向上、製作精度の向上等を図ることができる。
【００１８】
前記金属シェルは、前記オス型コネクタの挿入方向に沿って互いに平行に延びる一対の側板部分を有し、その側板部分に前記接触片が設けられていることが望ましい。側板部分に接触片を設けた場合、金属シェルの厚さに影響を及ぼさないようにして薄型化に寄与することができる。
【００１９】
前記金属シェルは金属板の加工により形成され、前記接触片は金属板の切り起こし片により形成されていることが望ましい。金属板の加工で金属シェルを形成した場合、その加工時に接触片も設けることができるので、その分、製作性も向上する。また、接触片が金属シェルと初めから一体化しているので、接触片を別部材として設ける場合に比べて接続不良等の問題も解消できる。
【００２０】
前記オス型コネクタは、その挿入部にコンタクトが設けられたカード型であり、その表面の少なくとも一部を前記導電体シールドで形成した構成を採用することもできる。さらに、前記オス型コネクタが、ケーブルの端部に接続されたプラグコネクタであり、前記メス型コネクタが、前記プラグコネクタが挿入される挿入口を有するリセプタクルコネクタである構成を採用することもできる。
【００２１】
【発明の実施の形態】
以下、添付の図１〜図４を参照し、本発明をカード用コネクタに適用した実施の形態について説明する。図１（ａ）は、カード用コネクタのシールド接続装置を示す要部の一部断面平面図である。図１（ｂ）は、その側面図である。
【００２２】
この実施の形態におけるカード用コネクタにおいても、基本的には図５に示した従来のカード用コネクタと同様に構成されている。即ち、ＩＣカード（オス型コネクタ）１０を挿入するメス型コネクタ３０側に接触片３６，３７を設けたカード用コネクタの例が示されている。このメス型コネクタ３０は、図１に示すように導電性の金属シェル３１を備えている。金属シェル３１には、ＩＣカード１０を挿入するための挿入口３２が設けられている。したがって、導電体シールドはこの金属シェル３１により形成されている。
【００２３】
金属シェル３１は、表裏の面板部分（一方の面板部分のみ図示）３３と、両側の側板部分３４、３５とを有する内部中空に形成されている。そして、両側の側板部分３４，３５に接触片３６，３７が設けられている。金属シェル３１は、金属板の加工により形成されている。したがって、接触片３６，３７は、側板部分３４，３５からの切り起こし片によって形成されている。
【００２４】
ＩＣカード１０は、その表面が同じく導電体シールドを形成する金属シェルにより覆われていている。ＩＣカード１０の挿入部の先端１１には、メス型コネクタ３０の例えばピンコンタクトに接続されるソケットコンタクト等（何れも図示せず）が設けられている。
【００２５】
次いで、これらの詳細について説明する。メス型コネクタ３０は、ＩＣカード１０の挿入口３２を備えている。接触片３６，３７は、挿入口３２の内壁から挿入口３２内に突出してＩＣカード１０の導電体シールドに接触する接点部３６Ａ、３７Ａと、挿入口３２の内壁よりも外側へ湾曲したＬ形の湾曲部３６Ｂ、３７Ｂとを備えている。そして、湾曲部３６Ｂ、３７Ｂは、接触片３６、３７の基端部３８、３９と接点部３６Ａ，３７Ａとの間にそれぞれ位置し、基端部３８，３９は湾曲部３６Ｂ、３７Ｂよりも挿入口３２の入口側に位置している。
【００２６】
接触片３６、３７の湾曲部３６Ｂ、３７Ｂは、ＩＣカード１０の挿入部先端１１のコーナ部分１４，１５が挿入口３２の内壁よりも外側へ進入するのを許容する曲率に設定されている。これは、ＩＣカード１０を斜めに挿しても、その挿入部先端のコーナ部分１４、１５を湾曲部３６Ｂ、３７Ｂによって許容し、接触片３６，３７の基端部３８，３９に大きな応力が作用しないように配慮するためである。
【００２７】
具体的には、接触片３６の湾曲部３６Ｂは、接触片３６の基端部３８から挿入口３２の内壁よりも外側（図１において左側）に向かって延びる第１斜辺部１と、その第１斜辺部１からの折り返し部２を介して接点部３６Ａに至る第２斜辺部３とを有している。第２斜辺部３は、折り返し部２から接点部３６Ａに向かうに従って挿入口３２の奥（図１において下側）に向かって延びる斜辺として形成されている。
【００２８】
一方、接触片３７の湾曲部３７Ｂは、接触片３７の基端部３９から挿入口３２の内壁よりも外側（図１において右側）に向かって延びる第１斜辺部１と、その第１斜辺部１からの折り返し部２を介して接点部３７Ａに至る第２斜辺部３とを有している。第２斜辺部３は、折り返し部２から接点部３７Ａに向かうに従って挿入口３２の奥（図１において下側）に向かって延びる斜辺として形成されている。
【００２９】
この構成によって、図４に示すように、基端部３８から延びる第１斜辺部１にＩＣカード１０の先端コーナ部分１４が第１斜辺部１に強く接触しないようにすることができる。また、第２斜辺部３はＩＣカード１０の先端コーナ部分１４のガイド斜面として作用し、接点部３６ＡをＩＣカード１０の導電体シールドに対して円滑に接触させる機能を発揮させることができる。
【００３０】
また、この実施の形態によれば、接触片３６，３７は、挿入口３２近くの内壁よりも外側へ湾曲した湾曲部３６Ｂ、３７Ｂを備え、この湾曲部３６Ｂ、３７Ｂは接点部３６Ａ，３７Ａよりも挿入口３２の入口側へそれぞれ位置している。したがって、図２および図３に示すように、ＩＣカード１０が正常に挿入されるとき、及びＩＣカード１０が図４に示すように斜めに挿入されても、挿入初期には湾曲部３６Ｂ、３７Ｂに接触せず、まず接点部３６Ａ、３７Ａにそれぞれ接触する。
【００３１】
その結果、接点部３６Ａ、３７Ａは基端部３８，３９から湾曲部３６Ｂ、３７Ｂが存在する分だけ離れているので、その基端部３８，３９に大きな応力が作用しない。これにより接触片３６，３７の変形をさらに効果的に防止することができる。
【００３２】
なお、実施の形態では、カード用コネクタに適用した例を示したが、本発明はこれに限定されることはない。例えば、ケーブルの端部に接続されるプラグコネクタと、プラグコネクタが挿入される挿入口を有するリセプタクルコネクタとからなるケーブルコネクタに本発明を適用することもできる。
【００３３】
【発明の効果】
以上のように、本発明に係るコネクタのシールド接続装置によれば、接触片の塑性変形を防止して、導電体シールド同士の電気的接続の信頼性向上を図ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a connector shield connecting device including a contact piece for connecting a conductor shield of a male connector and a conductor shield of a female connector.
[0002]
[Prior art]
A conductor shield is provided on a card connector or a cable connector into which a card containing an IC such as a memory is inserted or removed. In the case of a card connector, this conductor shield is provided for the purpose of preventing circuit destruction due to static electricity. In the case of a cable connector, the conductor shield is provided for the purpose of preventing electrical noise and crosstalk.
[0003]
As described above, the conductor shield is provided in both the male connector and the female connector, and is in contact with and electrically connected when the two connectors are coupled. At that time, a contact piece is often provided on one conductor shield side so as to ensure electrical connection between the conductor shields.
[0004]
5 to 8 show conventional examples of card connectors in which contact pieces are provided on the female connector 300 side into which an IC card (male connector) is inserted. The female connector 300 includes a conductive metal shell 301 as shown in FIG. The metal shell 301 is provided with an insertion port 302 for inserting the IC card 310. Therefore, the conductor shield is formed by this metal shell 301.
[0005]
The metal shell 301 is formed in a hollow interior having front and back face plate portions (only one face plate portion is shown) 303 and side plate portions 304 and 305 on both sides. Contact pieces 306 and 307 are provided on the side plate portions 304 and 305 on both sides. The metal shell 301 is usually formed by processing a metal plate. Therefore, the contact pieces 306 and 307 are formed by cut and raised pieces from the side plate portions 304 and 305.
[0006]
The surface of the IC card 310 is covered with a metal shell that also forms a conductor shield. At the distal end 311 of the insertion portion of the IC card 310, for example, a socket contact (not shown) connected to a pin contact of the female connector 300 is provided.
[0007]
When the IC card 310 is inserted into the female connector 300, the contact pieces 306 and 307 come into contact with the side surfaces 312 and 313 of the IC card 310 during the insertion process, and the conductor shields are electrically connected (FIGS. 6 and 6). 7).
[0008]
[Problems to be solved by the invention]
Such a conventional card connector has a problem that the contact pieces 306 and 307 are deformed. That is, the contact pieces 306 and 307 are provided near the mouth portion of the insertion port 302 as illustrated. Therefore, in the initial stage of insertion of the IC card 310, when the IC card 310 is inserted obliquely as shown in FIG. 8, one contact piece 306 may be pushed out and deformed.
[0009]
The deformation of the contact piece 306 becomes a plastic deformation of the base end portion 308 and does not return to the original state. As a result, there arises a problem that the reliability of electrical connection between the conductor shields via the contact pieces is lowered. When the IC card 310 is inserted obliquely toward the contact piece 307, the base end portion 309 of the contact piece 307 is plastically deformed.
[0010]
Such a problem is caused by the fact that the user often performs a “pick” operation when inserting the IC card 310. Further, when the reason why the plastic deformation of the contact piece is increased is considered, it has been found that the leading edge portion 315 of the IC card 310 becomes more prominent as it comes closer to the proximal end portion 308 of the contact piece 306 in FIG.
[0011]
These problems occur not only in the card connector but also in a cable connector provided with a conductor shield.
[0012]
Therefore, the subject of this invention is providing the shield connection apparatus of the connector which can aim at the reliability improvement of the electrical connection of conductor shields by preventing the plastic deformation of a contact piece.
[0013]
[Means for Solving the Problems]
The shield connection device for a connector according to the present invention includes a contact piece for connecting a conductor shield of a male connector and a conductor shield of a female connector, the female connector includes an insertion port of a male connector, The contact piece includes a contact portion that protrudes from the inner wall of the insertion port into the insertion port and contacts the conductor shield of the male connector, and a bending portion that is curved outward from the inner wall of the insertion port. The base end portion is positioned between the contact portion and the base end portion is positioned closer to the inlet side of the insertion port than the curved portion.
[0014]
According to the present invention, the contact piece includes a curved portion that is curved outward from the inner wall near the insertion port, and the curved portion is positioned closer to the inlet side of the insertion port than the contact portion. For this reason, even if the male connector is inserted obliquely, it does not contact the curved portion at the beginning of insertion, but first contacts the contact portion. Since the contact portion is separated from the base end portion by the amount of the curved portion, a large stress does not act on the base end portion of the contact piece. Thereby, a deformation | transformation of a contact piece can be prevented.
[0015]
The curved portion of the contact piece is preferably set to a curvature that allows the corner portion at the distal end of the insertion portion of the male connector to enter the outside of the inner wall of the insertion port. In this way, even if the male connector is inserted obliquely, the curved portion allows the corner portion at the distal end of the insertion portion, so that a large stress can be prevented from acting on the proximal end portion of the contact piece. That is, even if the corner portion enters the contact piece side, the curved portion exerts an action of releasing the corner portion.
[0016]
The curved portion of the contact piece includes a first oblique side portion that extends from the base end portion of the contact piece toward the outside of the inner wall of the insertion port, and a second portion that reaches the contact portion via a folded portion from the first oblique side portion. It is desirable that the second oblique side portion is formed as an oblique side extending toward the back of the insertion port as it goes from the folded portion toward the contact portion. If comprised in this way, it can prevent the front-end | tip corner part of a male connector from contacting the 1st oblique side part extended from a base end part strongly. Further, the second oblique side portion acts as a guide slope of the tip corner portion of the male connector, and exhibits a function of smoothly contacting the contact portion with the conductor shield of the male connector.
[0017]
The female connector preferably includes a conductive metal shell having an insertion opening, and a contact piece is provided on the metal shell.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment in which the present invention is applied to a card connector will be described with reference to FIGS. Fig.1 (a) is a partial cross-sectional top view of the principal part which shows the shield connection apparatus of the connector for cards. FIG. 1B is a side view thereof.
[0022]
The card connector in this embodiment is basically configured similarly to the conventional card connector shown in FIG. That is, an example of a card connector in which contact pieces 36 and 37 are provided on the female connector 30 side into which the IC card (male connector) 10 is inserted is shown. The female connector 30 includes a conductive metal shell 31 as shown in FIG. The metal shell 31 is provided with an insertion port 32 for inserting the IC card 10. Therefore, the conductor shield is formed by this metal shell 31.
[0023]
The metal shell 31 is formed in a hollow interior having front and back face plate portions (only one face plate portion is shown) 33 and side plate portions 34 and 35 on both sides. Contact pieces 36 and 37 are provided on the side plate portions 34 and 35 on both sides. The metal shell 31 is formed by processing a metal plate. Therefore, the contact pieces 36 and 37 are formed by cut and raised pieces from the side plate portions 34 and 35.
[0024]
The surface of the IC card 10 is covered with a metal shell that also forms a conductor shield. At the distal end 11 of the insertion portion of the IC card 10, a socket contact (not shown) connected to, for example, a pin contact of the female connector 30 is provided.
[0025]
Next, these details will be described. The female connector 30 includes an insertion slot 32 for the IC card 10. The contact pieces 36 and 37 protrude from the inner wall of the insertion slot 32 into the insertion slot 32 and contact with the conductor shields of the IC card 10 and L-shaped curved outward from the inner wall of the insertion slot 32. Curved portions 36B and 37B. The curved portions 36B and 37B are positioned between the base end portions 38 and 39 of the contact pieces 36 and 37 and the contact portions 36A and 37A, respectively, and the base end portions 38 and 39 are inserted more than the curved portions 36B and 37B. It is located on the entrance side of the mouth 32.
[0026]
The curved portions 36B and 37B of the contact pieces 36 and 37 are set to curvatures that allow the corner portions 14 and 15 of the insertion portion tip 11 of the IC card 10 to enter the outside of the inner wall of the insertion port 32. Even if the IC card 10 is inserted obliquely, the corner portions 14 and 15 at the tip of the insertion portion are allowed by the curved portions 36B and 37B, and a large stress acts on the base end portions 38 and 39 of the contact pieces 36 and 37. This is to avoid consideration.
[0027]
Specifically, the curved portion 36B of the contact piece 36 includes a first oblique side portion 1 extending from the base end portion 38 of the contact piece 36 to the outer side (left side in FIG. 1) than the inner wall of the insertion port 32, and the first oblique side portion 1 thereof. A second oblique side portion 3 extending from the first oblique side portion 1 to the contact portion 36A via the folded portion 2; The second oblique side portion 3 is formed as an oblique side extending toward the back of the insertion port 32 (downward in FIG. 1) as it goes from the folded portion 2 toward the contact portion 36A.
[0028]
On the other hand, the curved portion 37B of the contact piece 37 includes a first oblique side portion 1 extending from the base end portion 39 of the contact piece 37 toward the outer side (right side in FIG. 1) than the inner wall of the insertion port 32, and the first oblique side portion. 1 and a second oblique side portion 3 that reaches the contact portion 37A via the folded portion 2 from the first portion. The second oblique side portion 3 is formed as an oblique side extending toward the back (lower side in FIG. 1) of the insertion port 32 as it goes from the folded portion 2 toward the contact portion 37A.
[0029]
With this configuration, as shown in FIG. 4, it is possible to prevent the leading end corner portion 14 of the IC card 10 from coming into strong contact with the first oblique side portion 1 to the first oblique side portion 1 extending from the base end portion 38. Further, the second hypotenuse 3 acts as a guide slope of the tip corner portion 14 of the IC card 10 and can exert a function of smoothly bringing the contact portion 36A into contact with the conductor shield of the IC card 10.
[0030]
In addition, according to this embodiment, the contact pieces 36 and 37 include the curved portions 36B and 37B that are curved outward from the inner wall near the insertion port 32. The curved portions 36B and 37B are formed from the contact portions 36A and 37A. Are also located on the inlet side of the insertion port 32. Therefore, as shown in FIGS. 2 and 3, when the IC card 10 is normally inserted, and even when the IC card 10 is inserted obliquely as shown in FIG. 4, the curved portions 36B and 37B are initially inserted. First, the contact portions 36A and 37A are contacted respectively.
[0031]
As a result, the contact portions 36A and 37A are separated from the base end portions 38 and 39 by the amount of the curved portions 36B and 37B, so that a large stress does not act on the base end portions 38 and 39. Thereby, deformation of the contact pieces 36 and 37 can be more effectively prevented.
[0032]
In the embodiment, the example applied to the card connector is shown, but the present invention is not limited to this. For example, the present invention can be applied to a cable connector including a plug connector connected to an end portion of a cable and a receptacle connector having an insertion port into which the plug connector is inserted.
[0033]
