As shown in FIG. 2 (B), recesses 1220 extending in the length direction of the guide groove 18 are provided at locations on both sides in the width direction of the guide groove 18 of the contact piece mounting surface 1206.

電子機器側コネクタ１０の複数の接片１６について詳細に説明すると、図４（Ｆ）に示すように、各接片１６は、細幅で細長状の金属板材が屈曲されて構成され、それらの一端１６Ａが開口を介して接片取り付け面１２０６の上方に露出して配置され、図３（Ａ）に示すように、各接片１６の一端１６Ａが接片取り付け面１２０６上に露出する部分は長手方向が前記装着方向と一致して直線状に延在している。
電子機器側コネクタ１０の複数の接片１６の一端１６Ａは、図３（Ａ）に示すように、前記装着方向における端部がガイド溝１８の幅方向において直線上に位置するように並べられ、複数の接片１６のうちグランド電位に接続されるグランド接片１６０２は、その一端１６Ａが他の信号接片１６０４に比較して長手方向の寸法が大きく形成されており、グランド接片１６０２の一端１６Ａの前記取り外し方向における端部は他の信号接片１６０４の端部よりも突出している。言い換えると、複数の接片１６のうちグラウンド用の接片１６０２は他の接片１６よりも、ガイド溝１８の長さ方向で第１凸部２００４から第１凹部２００２に向かう方向に長く延在している。なお、図３（Ａ）において符号１６０５は電源用の接片を示している。
このような各接片１６０２，１６０４、１６０５のレイアウト（配置）は、アクセサリー側コネクタ２０を電子機器側コネクタ１０に装着する際に、図６に示すように、アクセサリー側コネクタ４０の接片４８のうちグランド電位に接続されるグランド接片４８０２が、他の信号接片４８０４に先行して、電子機器側コネクタ１０のグランド接片１６０２に接続させ、アクセサリー機器２００と電子機器１００の基準電位を最初にグランド電位にさせることで静電ノイズの影響を受けにくくするとともに、アクセサリー機器および電子機器の動作の安定化を図る目的でなされている。

Become.
Therefore, the space necessary for mounting the accessory-side connector 40 to the electronic device-side connector 10 includes the dimensions of the accessory-side connector 40 along the mounting direction and the mounting of the first and second locking pieces 5002, 5004. The sum of the direction dimensions is sufficient.
On the other hand, when the accessory-side connector 40 is mounted from outside the contour of the electronic device-side connector 10 as in the prior art, the dimension S is twice the dimension L of the accessory-side connector 40 along the mounting direction. Some 2L is required.
Therefore, it is not necessary to secure a wide space for mounting the accessory-side connector 40 around the electronic-device-side connector 10 as compared with the conventional case, so that the electronic device 100 and the accessory device 200 can be downsized, or This is extremely advantageous in improving the design of the electronic device 100 and the accessory device 200.
Further, the first convex portion 2004 of the electronic device side connector 10 that is locked to the first locking piece 2004 of the accessory side connector 40 and is held by the first locking piece 2004, that is, the accessory side connector 40 is fixed.

電子機器側コネクタ１０の複数の接片１６について詳細に説明すると、図１８（Ｆ）に示すように、各接片１６は、細幅で細長状の金属板材が屈曲されて構成され、それらの一端１６Ａが開口を介して接片取り付け面１２０６の上方に露出して配置され、図１７（Ａ）に示すように、各接片１６の一端１６Ａが接片取り付け面１２０６上に露出する部分は長手方向が前記装着方向と一致して直線状に延在している。
電子機器側コネクタ１０の複数の接片１６の一端１６Ａは、図１７（Ａ）に示すように、前記装着方向における端部がガイド溝１８の幅方向において直線上に位置するように並べられ、複数の接片１６のうちグランド電位に接続されるグランド接片１６０２は、その一端１６Ａが他の信号接片１６０４に比較して長手方向の寸法が大きく形成されており、グランド接片１６０２の一端１６Ａの前記取り外し方向における端部は他の信号接片１６０４の端部よりも突出している。言い換えると、複数の接片１６のうちグラウンド用の接片１６０２は他の接片１６よりも、ガイド溝１８の長さ方向で第１凸部２００４から第１凹部２００２に向かう方向に長く延在している。なお、図１７（Ａ）において符号１６０５は電源用の接片を示している。
このような各接片１６０２，１６０４、１６０５のレイアウト（配置）は、アクセサリー側コネクタ４０を電子機器側コネクタ１０に装着する際に、図２０に示すように、アクセサリー側コネクタ４０の接片４８のうちグランド電位に接続されるグランド接片４８０２が、他の信号接片４８０４に先行して、電子機器側コネクタ１０のグランド接片１６０２に接続させ、アクセサリー機器２００と電子機器１００の基準電位を最初にグランド電位にさせることで静電ノイズの影響を受けにくくするとともに、アクセサリー機器および電子機器の動作の安定化を図る目的でなされている。
また、本実施の形態では、２つのグランド接片１６０２が複数の接片１６のガイド溝１８の幅方向の両側に設けられている。
このような各接片１６０２，１６０４、１６０５のレイアウト（配置）は、アクセサリー側コネクタ４０がガイド溝１８の延在方向に対して傾斜して挿入された場合であっても、幅方向両側のグランド接片１６０２の何れか一方が、これらグランド接片１６０２に対応するアクセサリー側コネクタ４０のグランド接片４８０２（図２０参照）の何れかに接触することで、アクセサリー機器２００と電子機器１００の基準電位をより確実にグランド電位にさせ、静電ノイズの影響を受けにくくするとともに、アクセサリーおよび電子機器の動作のより一層の安定化を図る目的でなされている。
また、図１８（Ｆ）に示すように、各接片１６の一端１６Ａを除く部分は内側部材１２内部に配設され、接片１６の他端１６Ｂは、内側部材１２の前記装着方向の端部に開口された孔部１２０８内に導かれている。

これにより、フレキシブル基板１５０を介して電子機器１００内部の電気回路から各接片１６にアクセサリー機器２００を駆動するための電気信号が供給され、あるいは、各接片１６から電子機器１００内部の電気回路にアクセサリー機器２００からの電気信号が供給されるように構成されている。
この際、図２６に示すように、外側部材１４の底板部１４Ａが電子機器１００の凹部１１２の底面に取着される場合、外側部材１４に欠部１４０２が設けられているため、フレキシブル基板１５０を欠部１４０２内で屈曲させて電子機器１００の内部に導くことができる。
このため、上方から見てフレキシブル基板１５０が外側部材１４の輪郭の内側、すなわち電子機器側コネクタ１０の輪郭の内側に位置することになり、電子機器側コネクタ１０の外方にフレキシブル基板１５０を引き回すためのスペースを確保する必要がなく電子機器側コネクタ１０を取り付けるために必要なスペースを縮小する上で有利となる。
なお、図１８（Ｆ）において符号１２１１は外側部材１４の底面に突設された位置決め用のボスであり、このボス１２１１を電子機器１００の凹部１１２（図１参照）の底面に設けられた孔に係合させることでアクセサリー側コネクタ４０の位置決めを行うようになっている。 The contact pieces 16 of the electronic device-side connector 10 will be described in detail.

In this state, when the shaft portion 50 of the accessory-side connector 40 is moved in the removal direction, the first locking piece 5002 of the accessory-side connector 40 passes through the first recess 2002, and the second locking piece 5004 passes through the second recess 2006. It passes through the space 22 and moves upward, the shaft portion 50 of the accessory-side connector 40 is separated from the electronic device-side connector 10, and the accessory device 200 is removed from the electronic device 100.

本実施の形態によれば、電子機器側コネクタ１０にアクセサリー側コネクタ４０を装着する際に、アクセサリー側コネクタ４０の第１係止片５００２は第１凹部２００２を通り、第２係止片５００４は第２凹部２００６を通って空間部２２に位置させたのち、アクセサリー側コネクタ４０の軸部５０を前記装着方向に動かすことで第１係止片５００２を第１凸部２００４の下面に位置させ、第２係止片５００４を第２凸部２００８の下面に位置させた状態で電子機器側コネクタ１０の複数の接片１６にアクセサリー側コネクタ４０の複数の接片４８が接触する。
ここで、図２５、図２６を参照してアクセサリー側コネクタ４０を電子機器側コネクタ１０に装着するために必要なスペースの前記装着方向の寸法Ｓを考えると、本実施例では、第１、第２係止片５００２，５００４の前記装着方向の延在長さが軸部５０の前記装着方向の寸法の約１／３であるため、前記寸法Ｓは前記装着方向に沿ったアクセサリー側コネクタ４０の寸法（軸部５０の寸法）Ｌと、第１、第２係止片５００２，５００４の前記装着方向の寸法約Ｌ／３との和、すなわち寸法Ｓは約（Ｌ＋Ｌ／３）で済むことになる。
したがって、アクセサリー側コネクタ４０を電子機器側コネクタ１０に装着するために必要なスペースを、前記装着方向に沿ったアクセサリー側コネクタ４０の寸法と、第２係止片５００４の前記装着方向の寸法との和で済むことになる。
これに対して従来のようにアクセサリー側コネクタ４０を電子機器側コネクタ１０の輪郭の外側から装着する場合には、前記寸法Ｓは前記装着方向に沿ったアクセサリー側コネクタ４０の寸法Ｌの２倍である２Ｌ必要となる。
したがって、従来に比較して電子機器側コネクタ１０の周囲にアクセサリー側コネクタ４０を装着させるための広いスペースを確保する必要がなく、電子機器１００およびアクセサリー機器２００の小型化を図る上で、あるいは、電子機器１００およびアクセサリー機器２００のデザイン性を向上させる上で極めて有利となる。
また、操作リング４４を回動させることで、締め付け部７００４が第１凸部２００４と第２凸部２００８の上面に当接し第1係止片５００２および第２係止片５００４と協働して第１凸部２００４と第２凸部２００８を締め付け固定するとともに、移動阻止部７００６が第１凸部２００４と第２凸部２００８の間の第１凹部２００６に挿入され軸部５０のガイド溝１８の延在方向に沿った移動を阻止するので、アクセサリー側コネクタ４０を電子機器側コネクタ１０に対して強固に装着することができる。
したがって、ガイド溝１８の延在方向に沿った外力がアクセサリー側コネクタ４０に加わった場合に、アクセサリー側コネクタ４０が電子機器側コネクタ１０から脱落することを確実に防止する上で有利となる。 According to the present embodiment, when the accessory-side connector 40 is attached to the electronic device-side connector 10, the first locking piece 5002 of the accessory-side connector 40 passes through the first recess 2002, and the second locking piece 5004 is After being positioned in the space portion 22 through the second recess 2006, the first locking piece 5002 is positioned on the lower surface of the first protrusion 2004 by moving the shaft portion 50 of the accessory-side connector 40 in the mounting direction. The plurality of contact pieces 48 of the accessory-side connector 40 come into contact with the plurality of contact pieces 16 of the electronic device-side connector 10 with the second locking pieces 5004 positioned on the lower surface of the second convex portion 2008.
Here, referring to FIG. 25 and FIG. 26, considering the dimension S in the mounting direction of the space necessary for mounting the accessory-side connector 40 to the electronic device-side connector 10, Since the extension length of the two locking pieces 5002 and 5004 in the mounting direction is about 1/3 of the dimension of the shaft portion 50 in the mounting direction, the dimension S of the accessory-side connector 40 along the mounting direction is The sum of the dimension (dimension of the shaft portion 50) L and the dimension of the first and second locking pieces 5002 and 5004 in the mounting direction about L / 3, that is, the dimension S can be about (L + L / 3). Become.
Therefore, the space required for mounting the accessory-side connector 40 to the electronic device-side connector 10 is determined by the size of the accessory-side connector 40 along the mounting direction and the size of the second locking piece 5004 in the mounting direction. It will be all done with sum.
On the other hand, when the accessory-side connector 40 is mounted from outside the contour of the electronic device-side connector 10 as in the prior art, the dimension S is twice the dimension L of the accessory-side connector 40 along the mounting direction. Some 2L is required.
Therefore, it is not necessary to secure a wide space for mounting the accessory-side connector 40 around the electronic-device-side connector 10 as compared with the conventional case, so that the electronic device 100 and the accessory device 200 can be downsized, or This is extremely advantageous in improving the design of the electronic device 100 and the accessory device 200.
Further, by rotating the operation ring 44, the tightening portion 7004 comes into contact with the upper surfaces of the first and second convex portions 2004 and 2008 and cooperates with the first and second locking pieces 5002 and 5004. The first convex portion 2004 and the second convex portion 2008 are fastened and fixed, and the movement preventing portion 7006 is inserted into the first concave portion 2006 between the first convex portion 2004 and the second convex portion 2008, and the guide groove 18 of the shaft portion 50 is inserted. Therefore, the accessory side connector 40 can be firmly attached to the electronic device side connector 10.
Therefore, when an external force along the extending direction of the guide groove 18 is applied to the accessory-side connector 40, it is advantageous in reliably preventing the accessory-side connector 40 from dropping from the electronic device-side connector 10.

また、アクセサリー側コネクタ４０の第１係止片２００４に係止し第１係止片２００４により挟持される電子機器側コネクタ１０の第１凸部２００４を、すなわちアクセサリー側コネクタ４０を固定するための第１凸部２００４を、アクセサリー側コネクタ４０のばね片５２が弾接することでクリック感を発生させる部材として共用したので、部品点数の増加を抑制できコストダウンを図る上で有利となる。
また、アクセサリー側コネクタ４０の接片４８と電子機器側コネクタ１０の接片１６とが接続した状態で、ばね片５２が第１凸部２００４の端部に弾接するようにし、アクセサリー側コネクタ４０の仮止めを行うようにしたので、アクセサリー側コネクタ４０を固定するための第１凸部２００４を、アクセサリー側コネクタ４０の仮止めを行う部材として共用でき部品点数の増加を抑制できコストダウンを図る上で有利となる。 Further, the first convex portion 2004 of the electronic device side connector 10 that is locked to the first locking piece 2004 of the accessory side connector 40 and is held by the first locking piece 2004, that is, the accessory side connector 40 is fixed. Since the 1st convex part 2004 was shared as a member which produces a click feeling because the spring piece 52 of the accessory side connector 40 is elastically contacted, it is advantageous in reducing the number of parts and reducing costs.
Further, in a state where the contact piece 48 of the accessory-side connector 40 and the contact piece 16 of the electronic device-side connector 10 are connected, the spring piece 52 is elastically brought into contact with the end of the first convex portion 2004, so that the accessory-side connector 40 Since temporary fixing is performed, the first convex portion 2004 for fixing the accessory-side connector 40 can be shared as a member for temporarily fixing the accessory-side connector 40, so that an increase in the number of parts can be suppressed and cost reduction can be achieved. Is advantageous.

In the above invention, the first locking piece is positioned in the space portion through the first recess at a position between the first locking piece and the second locking piece at the tip of the shaft portion. The second locking piece is positioned in the first recess in a state where the second locking piece is positioned in the space through the second recess, and the first locking piece and the second locking piece are in the first protrusion in the space. When moving in the lower surface direction of the first convex portion and the second convex portion, it elastically contacts the tip of the first convex portion, and the first locking piece and the second locking piece are the first convex portion and the second convex portion.

このような発明によれば、電子機器側コネクタにアクセサリー側コネクタを装着する際に、アクセサリー側コネクタの第１係止片は第１凹部を通り、第２係止片は第２凹部を通って空間部に位置させたのち、アクセサリー側コネクタの軸部を前記装着方向に動かすことで第１係止片を第１凸部の下面に位置させ、第２係止片を第２凸部の下面に位置させた状態で電子機器側コネクタの複数の接片にアクセサリー側コネクタの複数の接片が接触する。
このため、アクセサリー側コネクタを電子機器側コネクタに装着するために必要なスペースの前記装着方向の寸法は、前記装着方向に沿ったアクセサリー側コネクタの寸法と、第１、第２係止片の前記装着方向の寸法との和で済むことになる。
したがって、従来のようにアクセサリー側コネクタを電子機器側コネクタの輪郭の外側から装着する場合に比較して電子機器側コネクタの周囲にアクセサリー側コネクタを装着させるための広いスペースを確保する必要がなく、電子機器およびアクセサリーの小型化を図る上で、あるいは、電子機器およびアクセサリーのデザイン性を向上させる上で極めて有利となる。
また、操作リングを回動させることで、締め付け部が第１凸部と第２凸部の上面に当接し第1係止片および第２係止片と協働して第１凸部と第２凸部を締め付け固定するとともに、移動阻止部が第１凸部と第２凸部の間の第１凹部に挿入され軸部のガイド溝の延在方向に沿った移動を阻止するので、アクセサリー側コネクタを電子機器側コネクタに対して強固に装着することができる。
したがって、ガイド溝の延在方向に沿った外力がアクセサリー側コネクタに加わった場合に、アクセサリー側コネクタが電子機器側コネクタから脱落することを確実に防止する上で有利となる。 According to such an invention, when attaching the accessory side connector to the electronic device side connector, the first locking piece of the accessory side connector passes through the first recess, and the second locking piece passes through the second recess. After being positioned in the space portion, the first locking piece is positioned on the lower surface of the first convex portion by moving the shaft portion of the accessory-side connector in the mounting direction, and the second locking piece is positioned on the lower surface of the second convex portion. The plurality of contact pieces of the accessory-side connector come into contact with the plurality of contact pieces of the electronic device-side connector in a state of being positioned at the position.
For this reason, the dimension in the mounting direction of the space necessary for mounting the accessory-side connector to the electronic device-side connector is the dimension of the accessory-side connector along the mounting direction and the first and second locking pieces. This is the sum of the dimensions in the mounting direction.
Therefore, it is not necessary to secure a wide space for attaching the accessory side connector around the electronic device side connector as compared with the case where the accessory side connector is attached from the outside of the contour of the electronic device side connector as in the past, This is extremely advantageous in reducing the size of electronic devices and accessories or improving the design of electronic devices and accessories.
Further, by rotating the operation ring, the tightening portion comes into contact with the upper surfaces of the first convex portion and the second convex portion, cooperates with the first locking piece and the second locking piece, and the first convex portion and the second convex portion. The two convex portions are fastened and fixed, and the movement preventing portion is inserted into the first concave portion between the first convex portion and the second convex portion and prevents movement along the extending direction of the guide groove of the shaft portion. The side connector can be firmly attached to the electronic device side connector.
Therefore, when an external force along the extending direction of the guide groove is applied to the accessory-side connector, it is advantageous in reliably preventing the accessory-side connector from dropping from the electronic device-side connector.
