Description

本発明は、電子機器にカードを接続するためのカードトレイ及びそれを使用したトレイ式カードコネクタに関する。   The present invention relates to a card tray for connecting a card to an electronic device and a tray-type card connector using the card tray.

従来、スマートフォン等の携帯電子端末の外部接続媒体には、表面に信号伝達用端子（電極パッド）が配置されているＩＣカードやフラッシュメモリーカード等のカードが使用されている。   Conventionally, a card such as an IC card or a flash memory card having a signal transmission terminal (electrode pad) disposed on the surface is used as an external connection medium of a portable electronic terminal such as a smartphone.

この種のカードとスマートフォン等の電子機器とを接続する手段としては、カードをカードトレイに収容し、そのカードトレイをハウジングに挿入するようにしたトレイ式のトレイ式カードコネクタが広く用いられている。   As a means for connecting this type of card to an electronic device such as a smartphone, a tray-type tray-type card connector in which the card is accommodated in a card tray and the card tray is inserted into the housing is widely used. .

トレイ式カードコネクタは、カードを収容するカードトレイと、カードトレイが挿入されるトレイ挿入部を有するハウジングと、ハウジング内に配設された導電性金属材からなるコンタクトとを備え、カードトレイをトレイ挿入部に挿入することによって、カード表面に配置された電極パッドとコンタクトとが接触し、ハウジングが実装された基板とカードとを電気的に接続するようになっている。   The tray-type card connector includes a card tray for storing a card, a housing having a tray insertion portion into which the card tray is inserted, and a contact made of a conductive metal material disposed in the housing. By inserting the card into the insertion part, the electrode pad arranged on the card surface and the contact come into contact with each other, and the board on which the housing is mounted and the card are electrically connected.

カードトレイには、表裏両面に開口したカード収容部を有する枠状のトレイ本体と、カード収容部の内周面より張り出したカード受け部とを備え、カード受け部にカード収容部内に嵌め込まれたカードの周縁を支持させ、カード収容部を通して電極パッドが下面側に露出するようにし、トレイ挿入部に挿入した際に、カード収容部を通して電極パッドとコンタクトとが接触できるようにしたものが知られている。   The card tray is provided with a frame-shaped tray body having card accommodating portions opened on both front and back surfaces, and a card receiving portion protruding from the inner peripheral surface of the card accommodating portion, and is fitted into the card receiving portion in the card receiving portion. It is known that the peripheral edge of the card is supported, the electrode pad is exposed to the lower surface side through the card housing portion, and the electrode pad and the contact can be contacted through the card housing portion when inserted into the tray insertion portion. ing.

従来、この種のカードトレイには、絶縁性合成樹脂材により一体成形されたものが知られているが、樹脂一体成形品は、ハウジングに対する挿抜を繰り返すと摩耗するおそれがあり、小型のものでは強度を確保することが困難な場合があった。   Conventionally, this type of card tray is known to be integrally molded from an insulating synthetic resin material. However, a resin integral molded product may be worn out by repeated insertion into and removal from the housing. In some cases, it was difficult to ensure the strength.

一方、この種のカードトレイには、削り出し加工等によって金属材で一体に成形されたものも知られているが、カードの電極パッドが配置された面をカード受け部で支持する構造であるため、電極パッドがカード受け部に接触し、短絡を生じるおそれがあった。   On the other hand, this type of card tray is also known to be integrally formed of a metal material by cutting or the like, but has a structure in which the surface on which the electrode pad of the card is arranged is supported by the card receiving portion. For this reason, the electrode pad may come into contact with the card receiving portion and cause a short circuit.

そのため、従来の金属製のカードトレイでは、カード受け部の表面に絶縁塗装等の短絡防止対策を必要とし、その分、製造費用が嵩むという問題があり、また、カードの出し入れによって絶縁塗装等の短絡防止対策が摩耗するという問題もあった。   For this reason, the conventional metal card tray requires a measure for preventing short circuit such as insulation coating on the surface of the card receiving part, and there is a problem that the manufacturing cost increases accordingly. There was also a problem that the short-circuit prevention measure was worn.

そこで、近年では、金属製板材を打抜き・折り曲げ加工することにより一体形成されたフレーム状の金属部と、この金属部と一体化された樹脂部とを備えたカードトレイも開発されている（例えば、特許文献１を参照）。   Therefore, in recent years, a card tray having a frame-like metal part integrally formed by punching and bending a metal plate material and a resin part integrated with the metal part has also been developed (for example, , See Patent Document 1).

そして、このカードトレイ１００は、図８に示すように、金属製底板部１０１の側縁を折り曲げて金属製側壁部１０２を形成し、金属製底板部１０１及び金属製側壁部１０２を樹脂１０３で肉付けすることによってカード収容部１０４の下縁にカード受け部１０５が形成された枠状に形成されている。   As shown in FIG. 8, the card tray 100 is formed by bending the side edge of the metal bottom plate portion 101 to form the metal side wall portion 102. The metal bottom plate portion 101 and the metal side wall portion 102 are made of resin 103. It is formed into a frame shape in which a card receiving part 105 is formed at the lower edge of the card accommodating part 104 by fleshing.

特開２０１６−１７３９８１号公報JP 2006-173981 A

しかしながら、上述の如き従来の技術では、金属部が金属製板材を打抜き・折り曲げ加工したものであるため、側壁の強度は、金属板材の板厚とそれと一体化された樹脂の厚みに依存するため、同じ厚みの金属製のトレイ式カードコネクタに比べ、側壁の強度が低下するという問題があった。   However, in the conventional technology as described above, since the metal part is obtained by punching and bending a metal plate, the strength of the side wall depends on the thickness of the metal plate and the thickness of the resin integrated therewith. There has been a problem that the strength of the side wall is lowered as compared with a metal tray-type card connector having the same thickness.

また、金属部のカード受け部を構成する部分は、樹脂との付着強度を確保するための孔や凹部が形成されており、板材の幅が一定でなく、幅の細い部分では強度が不足するおそれがあった。   In addition, the portion constituting the card receiving portion of the metal portion is formed with holes and concave portions for ensuring the adhesion strength with the resin, and the width of the plate material is not constant, and the strength is insufficient in the narrow portion. There was a fear.

そこで、本発明は、このような従来の問題に鑑み、カードの短絡を防止でき、且つ、簡便な構造で高い強度を備えたカードトレイ及びそれを使用したトレイ式カードコネクタの提供を目的としてなされたものである。   Therefore, in view of such conventional problems, the present invention has been made for the purpose of providing a card tray that can prevent a short circuit of a card and that has a simple structure and high strength, and a tray-type card connector using the card tray. It is a thing.

次に、本発明に係るカードトレイ及びそれを使用したトレイ式カードコネクタの実施態様を図１〜図７に示した実施例に基づいて説明する。尚、図中符号１はカード、符号２はカードトレイ、符号３はトレイ式カードコネクタである。   Next, embodiments of the card tray and the tray type card connector using the same according to the present invention will be described based on the embodiments shown in FIGS. In the figure, reference numeral 1 denotes a card, reference numeral 2 denotes a card tray, and reference numeral 3 denotes a tray-type card connector.

カード１は、例えば、ＳＩＭ等のＩＣカードであって、片方の面に複数の電極パッド１１，１１…が配置されている。   The card 1 is, for example, an IC card such as a SIM, and a plurality of electrode pads 11, 11... Are arranged on one surface.

トレイ式カードコネクタ３は、カード１が収容されるカードトレイ２と、カードトレイ２が挿入されるトレイ挿入部４１を有するハウジング４と、ハウジング４に配設された導電性金属材からなる複数のコンタクト５，５…とを備え、カード１を収容したカードトレイ２をトレイ挿入部４１に挿入することにより、各電極パッド１１，１１…が対応する各コンタクト５，５…と接触し、ハウジング４が実装された基板（図示せず）とカード１とを電気的に接続するようになっている。   The tray-type card connector 3 includes a card tray 2 in which the card 1 is accommodated, a housing 4 having a tray insertion portion 41 into which the card tray 2 is inserted, and a plurality of conductive metal materials disposed in the housing 4. Are provided with contacts 5, 5, and the card tray 2 containing the card 1 is inserted into the tray insertion portion 41, so that the electrode pads 11, 11. A board (not shown) on which the card is mounted and the card 1 are electrically connected.

カードトレイ２は、図２、図３に示すように、カード１が収容される表裏に開口したカード収容部６１が形成された枠状の金属製のトレイ本体６と、カード収容部６１の内周面に形成された樹脂接着強化部７と、樹脂接着強化部７を介してカード収容部６１の内周面に強固に固着された樹脂製カード受け部８，８とを備え、カード１を片面側（表面側）からカード収容部６１に嵌め込むことにより、カード１受け部にカード１の周縁が支持され、電極パッド１１，１１…がカード収容部６１を通して裏面側に露出した状態で収容されるようになっている。   As shown in FIGS. 2 and 3, the card tray 2 includes a frame-shaped metal tray main body 6 in which a card accommodating portion 61 opened on the front and back sides for accommodating the card 1 is formed, and an inner portion of the card accommodating portion 61. A resin bond reinforcing portion 7 formed on the peripheral surface, and resin card receiving portions 8 and 8 firmly fixed to the inner peripheral surface of the card accommodating portion 61 via the resin adhesive reinforcing portion 7. When the card 1 is fitted into the card housing 61 from one side (front side), the periphery of the card 1 is supported by the card 1 receiving portion, and the electrode pads 11, 11... Are exposed on the back side through the card housing 61. It has come to be.

トレイ本体６は、アルミニウムやステンレス等からなる金属製であって、ダイキャストやＭＩＭ（Ｍｅｔａｌ Ｉｎｊｅｃｔｉｏｎ Ｍｏｌｄｉｎｇ）によって一体に形成され、間隔を置いて平行に配置された一対の側枠部６２，６３と、両側枠部６２，６３の端部間を連結する前枠部６４及び後枠部６５とを備え、中央に表裏に開口したカード収容部６１を有する矩形枠状を成している。   The tray body 6 is made of metal made of aluminum, stainless steel, or the like, and is integrally formed by die casting or MIM (Metal Injection Molding). The front frame portion 64 and the rear frame portion 65 that connect between the end portions of the both side frame portions 62 and 63 are formed in a rectangular frame shape having a card accommodating portion 61 that is open to the front and back at the center.

側枠部６２，６３、前枠部６４及び後枠部６５は、図４（ａ）（ｂ）に示すように、図６に示す板材からなる金属部分に比べ幅が広く、それぞれ一定の幅を有する断面矩形状に形成され、高い剛性が確保されている。   As shown in FIGS. 4A and 4B, the side frame portions 62 and 63, the front frame portion 64, and the rear frame portion 65 are wider than the metal portion made of the plate material shown in FIG. The cross section is formed in a rectangular shape having high rigidity.

カード収容部６１は、側枠部６２，６３、前枠部６４及び後枠部６５からなる枠状の内側にカード１形状に整合させた形状に形成され、側枠部６２，６３と後枠部６５とに跨る傾斜部６６を備え、カード１の誤装填が防止されている。   The card accommodating portion 61 is formed in a shape aligned with the shape of the card 1 on the inner side of the frame shape including the side frame portions 62 and 63, the front frame portion 64, and the rear frame portion 65, and the side frame portions 62 and 63 and the rear frame An inclined portion 66 straddling the portion 65 is provided, and erroneous loading of the card 1 is prevented.

カード収容部６１の内周面、即ち、両側枠部６２，６３の内側面全体、前枠部６４の内側面及び後枠部６５の内側面には、樹脂接着強化部７が形成され、この樹脂接着強化部７を介して樹脂製の樹脂製カード受け部８，８がカード収容部６１の内側に固着されている。   The resin adhesion reinforcing portion 7 is formed on the inner peripheral surface of the card accommodating portion 61, that is, on the entire inner side surfaces of the both side frame portions 62 and 63, the inner side surface of the front frame portion 64, and the inner side surface of the rear frame portion 65. Resin-made resin card receiving portions 8, 8 are fixed to the inside of the card housing portion 61 through the resin adhesion reinforcing portion 7.

樹脂接着強化部７は、例えば、カード収容部６１の内周面を接着強化被膜７１で被覆することにより形成されている。   The resin adhesion strengthening part 7 is formed by, for example, covering the inner peripheral surface of the card accommodating part 61 with an adhesion reinforcing film 71.

そして、インサート成形によって側枠部６２，６３の内側に樹脂製カード受け部８，８を形成する際、接着強化被膜７１が金属及び樹脂のそれぞれと化学反応し、接着剤を用いずに金属製の側枠部６２，６３と樹脂製の樹脂製カード受け部８，８とが強固に固着されるようになっている。   When the resin card receiving portions 8 and 8 are formed inside the side frame portions 62 and 63 by insert molding, the adhesion reinforcing coating 71 chemically reacts with each of the metal and the resin, and is made of metal without using an adhesive. The side frame portions 62 and 63 and the resin-made resin card receiving portions 8 and 8 are firmly fixed to each other.

尚、樹脂接着強化部７の態様は、上述の接着強化被膜７１に限定されず、例えば、金属製の側枠部６２，６３の内周面表面を酸化させること等の化学的表面処理、ヤスリ掛け等による物理的表面処理、アルマイト処理やエッチング等の表面処理によって側枠部６２，６３の表面に無数の微小な凹凸が形成されたものであってもよい。   The form of the resin adhesion strengthening portion 7 is not limited to the above-described adhesion strengthening coating 71, and for example, chemical surface treatment such as oxidizing the inner peripheral surface of the metal side frame portions 62 and 63, a file, etc. An infinite number of minute irregularities may be formed on the surfaces of the side frame portions 62 and 63 by physical surface treatment such as hanging, surface treatment such as alumite treatment or etching.

その場合、樹脂接着強化部７は、微小な凹凸によって摩擦係数が高くなり、インサート成形によって側枠部６２，６３の内側に樹脂製カード受け部８，８が形成された際、金属製の側枠部６２，６３と樹脂製の樹脂製カード受け部８，８とが強固に固着されるとともに、トレイ本体６と樹脂製カード受け部８，８との間のせん断強度が高くなる。   In that case, the resin adhesion strengthening portion 7 has a high coefficient of friction due to minute irregularities, and when the resin card receiving portions 8 and 8 are formed inside the side frame portions 62 and 63 by insert molding, the resin side is made of metal. The frame portions 62 and 63 and the resin-made resin card receiving portions 8 and 8 are firmly fixed, and the shear strength between the tray body 6 and the resin-made card receiving portions 8 and 8 is increased.

さらに、樹脂接着強化部７は、微小凹凸を形成する表面処理と接着強化被膜７１とを併用してもよい。   Furthermore, the resin adhesion strengthening part 7 may use both the surface treatment for forming minute irregularities and the adhesion reinforcing coating 71.

また、樹脂接着強化部７は、図４に示すように、側枠部６２，６３の内側面に凹状の補強凹部７２を形成しておき、樹脂製カード受け部８，８の接着面より突出した補強凸部７３と互いに嵌合するようにし、上記接着強化被膜７１又は微小凹凸を形成する表面処理による固着強度に加え、補強凹部７２と補強凸部７３の嵌合によるトレイ厚み方向のせん断強度を強化してもよい。尚、補強凹部７２及び補強凸部７３は、側枠部６２，６３側に補強凸部７３を突設し、樹脂製カード受け部８，８側に補強凹部７２を形成してもよい。   Further, as shown in FIG. 4, the resin adhesion strengthening portion 7 has a concave reinforcing recess 72 formed on the inner side surfaces of the side frame portions 62 and 63, and protrudes from the adhesion surface of the resin card receiving portions 8 and 8. In addition to the fixing strength by the surface treatment for forming the adhesion reinforcing coating 71 or the fine unevenness, the reinforcing strength 73 is fitted to each other, and the shear strength in the tray thickness direction by the fitting of the reinforcing concave 72 and the reinforcing convex 73 May be strengthened. In addition, the reinforcement recessed part 72 and the reinforcement convex part 73 may protrude the reinforcement convex part 73 in the side frame parts 62 and 63 side, and may form the reinforcement recessed part 72 in the resin-made card receiving parts 8 and 8 side.

この補強凹部７２及び補強凸部７３は、側枠部６２，６３の内側面部に予め補強凹部７２又は補強凸部７３を形成するとともに接着強化被膜７１を形成し、補強凹部７２の内面又は補強凸部７３の外面を接着強化被膜７１で覆った状態とし、その状態でインサート成形によって側枠部６２，６３の内側に樹脂製カード受け部８，８を形成することによって互いに嵌合される。   The reinforcing concave portion 72 and the reinforcing convex portion 73 form the reinforcing concave portion 72 or the reinforcing convex portion 73 in advance on the inner side surface portions of the side frame portions 62 and 63 and also form the adhesion reinforcing coating 71. The outer surface of the portion 73 is covered with the adhesion reinforcing coating 71, and in this state, the resin card receiving portions 8 and 8 are formed inside the side frame portions 62 and 63 by insert molding to be fitted to each other.

樹脂製カード受け部８，８は、図４（ａ）に示すように、一定の厚みを有する帯状に形成され、側枠部６２，６３及び前後枠部６５の内側下縁に固定され、収容されたカード１の側縁を支持するようになっている。   As shown in FIG. 4A, the resin card receiving portions 8 and 8 are formed in a band shape having a certain thickness, and are fixed to the inner lower edges of the side frame portions 62 and 63 and the front and rear frame portions 65, and accommodated therein. The side edge of the card 1 is supported.

尚、樹脂製カード受け部８，８は、図４（ｂ）に示すように、カード収容部６１の内側面を構成する側板部８１と、側板部８１の下縁より内側に張り出した受け部本体８２とを備え、断面Ｌ字状に一体成形されたものであってもよい。   As shown in FIG. 4B, the resin card receiving portions 8, 8 include a side plate portion 81 that forms the inner surface of the card housing portion 61 and a receiving portion that protrudes inward from the lower edge of the side plate portion 81. The main body 82 may be provided, and it may be integrally formed to have an L-shaped cross section.

この場合、側板部８１全体が樹脂接着強化部７を介してカード収容部６１の内側面に固着されるので、金属と樹脂との接着面積を広くとることができ、より強固に金属と樹脂とを固着させるこができる。   In this case, since the entire side plate portion 81 is fixed to the inner side surface of the card housing portion 61 via the resin adhesion strengthening portion 7, the bonding area between the metal and the resin can be increased, and the metal and the resin can be more firmly bonded. Can be fixed.

このように構成されたカードトレイ２及びそれを使用したトレイ式カードコネクタ３は、トレイ本体６が一定の幅及び高さを有する金属製の各枠部６２〜６４によって枠状に形成されているので、小型化によっても高い強度を確保することができる。   In the card tray 2 configured as described above and the tray-type card connector 3 using the card tray 2, the tray body 6 is formed in a frame shape by metal frame portions 62 to 64 having a certain width and height. Therefore, high strength can be ensured even by downsizing.

また、樹脂製の樹脂製カード受け部８，８は、樹脂接着強化部７を介して強固に固着されていることに加え、高い剛性を備えた枠状のカード１本体に支持されているので、枠の歪みによる変形が防止される。   In addition, the resin-made resin card receiving portions 8 and 8 are supported by the frame-like card 1 body having high rigidity in addition to being firmly fixed via the resin adhesion reinforcing portion 7. , Deformation due to frame distortion is prevented.

また、このカードトレイ２は、金属製のトレイ本体６と樹脂製の樹脂製カード受け部８，８とが強固に固着されているので、金属製のカード１本体に対する樹脂の付着強度を孔や凹部に依存する必要が無く、その分、金属部分の幅を十分に確保し、断面欠損等も低減できるので、トレイ全体の高い強度を得ることができる。   In addition, since the metal tray body 6 and the resin resin card receiving portions 8 and 8 are firmly fixed to the card tray 2, the adhesion strength of the resin to the metal card 1 body is reduced by holes or holes. There is no need to depend on the recess, and the width of the metal portion can be secured sufficiently and the cross-sectional defects can be reduced accordingly, so that high strength of the entire tray can be obtained.

尚、上述の実施例では、カード１としてＳＩＭカード等のＩＣカードを例に説明したが、カード１の態様はこれに限定されず、例えば、マイクロＳＤカード等のメモリーカードであってもよい。   In the above-described embodiment, an IC card such as a SIM card is described as an example of the card 1, but the mode of the card 1 is not limited to this, and may be a memory card such as a micro SD card.

また、カードトレイ２の形状は、上述の実施例に限定されず、例えば、図５に示すように、側枠部６２の下面６２ａに樹脂接着強化部７を介して樹脂製カード受け部８の上面８ａを固着させてもよい。   Further, the shape of the card tray 2 is not limited to the above-described embodiment. For example, as shown in FIG. 5, the resin card receiving portion 8 is formed on the lower surface 62 a of the side frame portion 62 via the resin adhesion reinforcing portion 7. The upper surface 8a may be fixed.

さらに、カードトレイ２は、図６に示すように、トレイ本体６にカード収容部６１側に開口し、樹脂カード受け部８の側部８ｂが嵌合される嵌合凹部９を備え、この嵌合凹部９内に樹脂接着強化部７が形成されているものであってもよい。尚、嵌合凹部９は、樹脂カード受け部８の厚みと同じ上下幅である凹溝状に形成され、図６(ａ)（ｂ）に示すように、任意の位置とすることができる。   Further, as shown in FIG. 6, the card tray 2 includes a fitting recess 9 that is open on the tray body 6 toward the card accommodating portion 61 and into which the side portion 8 b of the resin card receiving portion 8 is fitted. The resin adhesion strengthening part 7 may be formed in the joint recess 9. In addition, the fitting recessed part 9 is formed in the concave groove shape which is the same vertical width as the thickness of the resin card receiving part 8, and can be made into arbitrary positions as shown to Fig.6 (a) (b).

さらにまた、カードトレイ２は、図７に示すように、２枚のカード１を収容できるものであってもよい。尚、上述の実施例と同様の構成には、同一符号を付して説明を省略する。   Furthermore, the card tray 2 may be capable of accommodating two cards 1 as shown in FIG.
