また、トレイ本体31には、後縁部の軸用凸部6に整合させた位置に凹み状の回避用凹部34が形成され、カードトレイ3(トレイ本体31)をトレイ挿入部41に挿入した際に軸用凸部6が回避用凹部34に回避し、ハウジング4に占める軸用凸部6のスペースとカードトレイ3のハウジング4に占めるスペースとが重複するようになっている。   The tray main body 31 is formed with a concave avoidance concave portion 34 at a position aligned with the axial convex portion 6 at the rear edge, and the card tray 3 (tray main body 31) is inserted into the tray insertion portion 41. At this time, the shaft convex portion 6 avoids the avoidance concave portion 34, and the space of the shaft convex portion 6 occupying the housing 4 and the space occupying the housing 4 of the card tray 3 overlap each other.

回避用凹部34は、軸用凸部6の突端61とハウジング4の底板部421との間に挿入される底部341を備えた形状に形成され、回避用凹部34を設けたことによるトレイ本体31後縁部の欠損を最小限に抑えている。   The avoidance recess 34 is formed in a shape having a bottom portion 341 inserted between the protruding end 61 of the shaft protrusion 6 and the bottom plate portion 421 of the housing 4, and the tray main body 31 by providing the avoidance recess 34. Minimizing trailing edge loss.

前面蓋部32は、筐体開口部に嵌り込む蓋本体321と、蓋本体321の後面に一体に突設された連結部322とを備え、連結部322をトレイ本体31の前端部と連結することによりカードトレイ3の前端部にフランジ状に固定され、トレイ本体31と前面蓋部32とが一体化されている。   The front lid portion 32 includes a lid main body 321 that fits into the opening of the housing and a connecting portion 322 that protrudes integrally with the rear surface of the lid main body 321, and connects the connecting portion 322 to the front end portion of the tray main body 31. Thus, the front end of the card tray 3 is fixed in a flange shape, and the tray main body 31 and the front cover 32 are integrated.

また、蓋本体321には、一方の側部後面に突出した凸部323が一体に備えられ、蓋本体321の前面に開口したトレイ挿抜方向に向けたピン挿通孔324が操作部材8の位置と連続配置となるように形成され、このピン挿通孔324に操作用ピン35がトレイ挿抜方向に移動可能に収容されている。   Further, the lid body 321 is integrally provided with a convex portion 323 that protrudes from the rear surface of one side, and a pin insertion hole 324 that opens in the front surface of the lid body 321 and faces in the tray insertion / removal direction corresponds to the position of the operation member 8. The operation pins 35 are accommodated in the pin insertion holes 324 so as to be movable in the tray insertion / removal direction.

このように構成されたトレイ式カードコネクタ2では、押出しレバー7を軸用凸部6に当接させ、軸用凸部6回りに回転するようにした構造としたことにより、軸穴を必要とせず、従来例の如く押出しレバーの軸穴周囲に幅を必要としないため、押出しレバー7自体の前後方向幅を小さくできる。   In the tray-type card connector 2 configured as described above, the push lever 7 is brought into contact with the shaft convex portion 6 so as to rotate around the shaft convex portion 6 so that a shaft hole is not required. First, since a width is not required around the shaft hole of the extrusion lever as in the conventional example, the width in the front-rear direction of the extrusion lever 7 itself can be reduced.

また、押出しレバー7の小型化に加え、図7、図8に示すように、カードトレイ3(トレイ本体31)をハウジング4のトレイ挿入部41に挿入した際、軸用凸部6が回避用凹部34内に回避し、ハウジング4に占める軸用凸部6のスペースとカードトレイ3のハウジング4に占めるスペースとが重複するようにしたことにより、その分、ハウジング4の前後方向長さを短縮でき、コネクタ全体の小型化を図ることができる。   Further, in addition to the miniaturization of the pushing lever 7, as shown in FIGS. 7 and 8, when the card tray 3 (tray body 31) is inserted into the tray insertion portion 41 of the housing 4, the shaft convex portion 6 is for avoidance. By avoiding the recess 34, the space of the projection 6 for the shaft occupying the housing 4 and the space occupying the housing 4 of the card tray 3 are overlapped, thereby shortening the length of the housing 4 in the front-rear direction. Thus, the entire connector can be reduced in size.

尚、カードトレイ3が誤挿入された場合、例えば、表裏逆に挿入された場合には、回避用凹部34の位置が軸用凸部6と整合せず、トレイ本体31の後縁が軸用凸部6と接触して最後まで挿入できないようになっている。   When the card tray 3 is erroneously inserted, for example, when the card tray 3 is inserted upside down, the position of the avoidance concave portion 34 is not aligned with the axial convex portion 6 and the trailing edge of the tray main body 31 is the axial end. It cannot be inserted to the end in contact with the convex portion 6.

一方、カードトレイ3の引き出しは、棒状のピン材を前端開口よりピン挿通孔324に挿し込み、操作用ピン35の前端を押し込み方向に押圧すると、図9に示すように、操作用ピン35がピン挿通孔324内を移動し、後端側が凸部323の後端より突出し、操作部材8を後方に向けて押し込むにより、押出しレバー7の一端が操作部材8に押し込まれる。   On the other hand, when the card tray 3 is pulled out, when a rod-shaped pin material is inserted into the pin insertion hole 324 from the front end opening and the front end of the operation pin 35 is pressed in the pressing direction, as shown in FIG. By moving through the pin insertion hole 324, the rear end side protrudes from the rear end of the convex portion 323, and the operation member 8 is pushed backward, whereby one end of the pushing lever 7 is pushed into the operation member 8.

そして、押出しレバー7は、後方に後壁部423が配置され、且つ、前面側の屈曲部73が軸用凸部6に当接した状態にあるので、一端が押し込まれると、軸用凸部6回りに回転し、それに伴い押出しレバー7の端部がカードトレイ3の後端縁を押圧し、カードトレイ3を抜け出し方向に押し出すようになっている。   And, since the rear wall portion 423 is disposed on the rear side of the pushing lever 7 and the front-side bent portion 73 is in contact with the shaft convex portion 6, when one end is pushed in, the shaft convex portion The end of the extrusion lever 7 presses the rear edge of the card tray 3 along with the rotation, and the card tray 3 is pushed out in the withdrawal direction.

尚、上述の実施例では、回避用凹部34に底部341を一体に備えた例について説明したが、底部341を有しない切欠き状に形成してもよい。   In the above-described embodiment, the example in which the bottom portion 341 is integrally provided in the avoidance concave portion 34 has been described, but it may be formed in a notch shape without the bottom portion 341.

また、上述の実施例では、軸用凸部6をシールドカバー43の天板部431より突出させた例について説明したが、軸用凸部6をハウジング本体42の底板部421より突出させるようにしてもよい。   In the above-described embodiment, the example in which the shaft convex portion 6 is projected from the top plate portion 431 of the shield cover 43 has been described. However, the shaft convex portion 6 is projected from the bottom plate portion 421 of the housing body 42. May be.

その場合、回避用凹部34の底部341は、軸用凸部6の突端61と天板部431との間に挿入されるように形成される。   In that case, the bottom portion 341 of the avoidance recess 34 is formed so as to be inserted between the protruding end 61 of the shaft protrusion 6 and the top plate portion 431.

尚、上述の実施例では、操作部材8と操作用ピン35とを別々に設けた例について説明したが、操作用ピン35を操作部材8の前端に一体に備えるようしてもよい。その場合、カードトレイ3の挿抜及び押出しレバー7の双方と連動して操作部材8が挿抜方向で移動する。   In the above-described embodiment, the example in which the operation member 8 and the operation pin 35 are separately provided has been described. However, the operation pin 35 may be integrally provided at the front end of the operation member 8. In that case, the operation member 8 moves in the insertion / extraction direction in conjunction with both the insertion / extraction of the card tray 3 and the push lever 7.
