まず、図１に基づいて、コネクタ１０に使用する５つのカム構造について説明する。
第一番目は、図１（Ａ）のように、回動部材１８１のカム部５４を任意に変化させた回動部材１８１を交換することにより、他の部品との接触若しくは非接触させる位置を変えるものである。この方法は、必要な分だけの回動部材１８１を予め用意しておき、仕様に応じて回動部材１８１を交換するものである。図１（Ａ）の回動部材１８１は、前記回動部材１８１を回動（回転）させることにより、１６〜６９端子が接触し、１〜１５端子と７０〜８５端子が接触しない（非接触）構造になっている。交換方式の別の回動部材１８１としては、例えば、図２（Ａ）のように、前記回動部材１８１を回動（回転）させることにより、１〜３０端子と５６〜８５端子が接触し、３１〜５５端子が接触しない（非接触）構造になっている。
第二番目は、図１（Ｂ）のように、回動部材１８２を所定の距離だけ移動することにより他の部品との接触若しくは非接触させる位置を変えるものである。この方法は、１つの回動部材１８２を使用し、仕様に応じて回動部材１８２を挿入方向に前後させることにより、接触若しくは非接触させる部分を変化させるものである。図１（Ｂ）の回動部材１８２は、前記回動部材１８２を回動（回転）させることにより、１〜１０端子と２１〜３０端子と４１〜５０端子と６１〜７０端子と８１〜８５端子が接触し、１１〜２０端子と３１〜４０端子と５１〜６０端子と７１〜８０端子が接触しない（非接触）構造になっている。
第三番目は、図１（Ｃ）のように、回動部材１８３のカム部５４の回動（回転）方向を逆方向に、９０度回動（回転）させることにより他の部品との接触若しくは非接触させる位置を変えるものである。この方法は、１つの回動部材１８３を使用し、回動（回転）方向を変えることにより同一箇所で接触若しくは非接触を変化させるものである。つまり、回動部材１８３を９０度若しくは−９０度回動（回転）させることにより同一箇所で、接触と非接触かを変えるものである。図１（Ｃ）の回動部材１８３は、前記回動部材１８３を挿入方向に対して９０度回動（回転）させることにより、１〜４０端子が接触し、４１〜８５端子が接触しない（非接触）構造で、前記回動部材１８３を挿入方向に対して−９０度回動（回転）させることにより、４１〜８５端子が接触し、１〜４０端子が接触しない（非接触）構造になっている。
また、図示はしないが、次のようなカム構造も可能である。
第四番目は、第一番目と第三番目とを組合わせたものである。つまり、交換方式の回動部材１８１に、逆回動（回転）することで接触若しくは非接触することができる（第三場番目）構造を任意に箇所に形成しておけば、芯数毎の接触／非接触も可能で、かつ、同一箇所での接触／非接触も可能になる。
第五番目は、第二番目と第三番目とを組合わせたものである。つまり、移動方式の回動部材１８２に、逆回動（回転）することで接触若しくは非接触することができる（第三場番目）構造を任意に箇所に形成しておけば、芯数毎の接触／非接触も可能で、かつ、同一箇所での接触／非接触も可能になる。
First, the five cam structures used for the connector 10 will be described with reference to FIG.
First, as shown in FIG. 1A, by replacing the rotating member 181 in which the cam portion 54 of the rotating member 181 is arbitrarily changed, the position to be brought into contact or non-contact with other components is set. To change. In this method, as many rotating members 181 as necessary are prepared in advance, and the rotating members 181 are replaced according to specifications. The rotating member 181 in FIG. 1A rotates (rotates) the rotating member 181 so that terminals 16 to 69 are in contact with each other, and terminals 1 to 15 and terminals 70 to 85 are not in contact (non-contacting). ) It has a structure. As another rotating member 181 of the exchange system, for example, as shown in FIG. 2A, by rotating (rotating) the rotating member 181, the terminals 1 to 30 and 56 to 85 are brought into contact with each other. 31 to 55 terminals are not in contact (non-contact).
Secondly, as shown in FIG. 1B, the position where the rotating member 182 is brought into contact or non-contact with other components is changed by moving the rotating member 182 by a predetermined distance. In this method, one rotating member 182 is used, and the rotating member 182 is moved back and forth in the insertion direction according to the specification, thereby changing the contact or non-contact portion. The rotating member 182 of FIG. 1 (B) rotates (rotates) the rotating member 182 so that 1-10 terminals, 21-30 terminals, 41-50 terminals, 61-70 terminals, 81-85. The terminals are in contact, and the 11-20 terminal, 31-40 terminal, 51-60 terminal, and 71-80 terminal do not contact (non-contact).
Third, as shown in FIG. 1 (C), contact with other parts is achieved by rotating (rotating) the cam portion 54 of the rotating member 183 in the opposite direction by rotating (rotating) 90 degrees. Alternatively, the non-contact position is changed. This method uses one rotating member 183 and changes contact (or non-contact) at the same location by changing the rotation (rotation) direction. That is, by rotating (rotating) the rotating member 183 by 90 degrees or -90 degrees, it is changed between contact and non-contact at the same location. The rotating member 183 in FIG. 1C rotates the rotating member 183 by 90 degrees with respect to the insertion direction, so that the 1 to 40 terminals are in contact with each other and the 41 to 85 terminals are not in contact with each other ( With the non-contact structure, the rotation member 183 is rotated (rotated) by −90 degrees with respect to the insertion direction, so that the terminals 41 to 85 are in contact and the terminals 1 to 40 are not in contact (non-contact). It has become.
Although not shown, the following cam structure is also possible.
The fourth is a combination of the first and third. In other words, if a structure that can be contacted or non-contacted by reversely rotating (rotating) (third field) structure is arbitrarily formed in the exchange-type rotating member 181, Contact / non-contact is possible, and contact / non-contact at the same location is also possible.
The fifth is a combination of the second and third. That is, if a structure (third field) that can be contacted or non-contacted by reversely rotating (rotating) the rotating member 182 of the moving system is formed at any location, the number of cores Contact / non-contact is possible, and contact / non-contact at the same location is also possible.
以下で、上記カム構造を使用した回動部材１８１、１８２、１８３について説明する。この回動部材１８１、１８２、１８３は電気絶縁性のプラスチックであり、公知技術の射出成形によって製作され、この材質としては寸法安定性や加工性やコスト等を考慮して適宜選択するが、一般的にはポリブチレンテレフタレート（ＰＢＴ）やポリアミド（６６ＰＡ、４６ＰＡ）や液晶ポリマー（ＬＣＰ）やポリカーボネート（ＰＣ）やこれらの合成材料を挙げることができる。
Hereinafter, the rotating members 181, 182, and 183 using the cam structure will be described. The rotating members 181, 182, and 183 are electrically insulating plastics, and are manufactured by a known technique of injection molding. The material is appropriately selected in consideration of dimensional stability, workability, cost, etc. Specifically, polybutylene terephthalate (PBT), polyamide (66PA, 46PA), liquid crystal polymer (LCP), polycarbonate (PC), and synthetic materials thereof can be used.
前記回動部材１８１、１８２、１８３は主に前記回動部材１８１、１８２、１８３を操作する操作部５６と前記コンタクト１４、１６の押受部３２を押圧するカム部５４を備えている。本実施例では、前記回動部材１８１、１８２、１８３を略棒状片にしている。
第二番目の移動方式（図１（Ｂ）のタイプ）は、図１（Ｂ）及び図２（Ｂ）のように１芯ごとに突起６４を設け、移動した後に前記突起６４を隣接する前記コンタクト１４、１６間に入れることで位置決めを行っている。また、別の方法としては、回動部材１８２の長手方向両側若しくは一方側に複数の係合孔を設け、該係合孔に入る係合部材を準備しておき、該係合部材を所定の位置の前記係合孔に係合することで位置決めと移動距離を決めている。
The rotating members 181, 182, and 183 mainly include an operation portion 56 that operates the rotating members 181, 182, and 183 and a cam portion 54 that presses the pressing portion 32 of the contacts 14 and 16. In this embodiment, the rotating members 181, 182 and 183 are substantially rod-shaped pieces.
In the second movement method (type of FIG. 1 (B)), as shown in FIGS. 1 (B) and 2 (B), a protrusion 64 is provided for each core, and the protrusion 64 is adjacent to the protrusion 64 after moving. Positioning is performed by placing the contact between the contacts 14 and 16. As another method, a plurality of engagement holes are provided on both sides or one side of the rotating member 182 in the longitudinal direction, and an engagement member that enters the engagement hole is prepared. Positioning and moving distance are determined by engaging with the engaging hole at the position.
前記回動部材１８１、１８２、１８３の前記カム部５４は、コンタクト１４、１６の押受部３２に押し付ける部分である。その形状としては、前記コンタクト１４、１６の接触部２６が接続対象物に接触するか接触しないかによって適宜設計する。前記コンタクト１４、１６の接触部２６を接続対象物（ＦＰＣ８０）に接触させたい場合は、細長形状にすることが望ましく、本実施例では略楕円形状をしている。このように楕円形状にすることによって、コンタクト１４、１６の押受部３２と接続部４０の突出台４４との間で回転させることで、カム部５４の大きさの変化によりコンタクト１４、１６の押受部３２が持ち上げられ、ＦＰＣ８０をコンタクト１４、１６の接触部２６側に押し付けている。接触させる部分のカム部５４の形状としては、コンタクト１４、１６の押受部３２と接続部４０の突出台４４との間で回転でき、長軸と短軸といった大きさの違いによりコンタクト１４、１６の押受部３２を押し上げられ、図８から図１３のように前記コンタクト１４、１６の接触部２６が接続対象物（ＦＰＣ８０）に接触すれば、如何なるものでもよい。接触させる部分の前記カム部５４の形状や大きさは、このようなことを考慮して適宜設計する。
The cam portions 54 of the rotating members 181, 182, and 183 are portions that are pressed against the pressing portions 32 of the contacts 14 and 16. The shape is appropriately designed depending on whether or not the contact portions 26 of the contacts 14 and 16 are in contact with the connection object. When the contact portions 26 of the contacts 14 and 16 are desired to come into contact with the connection object (FPC 80), it is desirable that the contact portions 26 have an elongated shape. In this embodiment, the contact portions 26 have a substantially elliptical shape. By making it oval in this way, by rotating between the pressing portion 32 of the contacts 14 and 16 and the protruding base 44 of the connection portion 40, the size of the cam portion 54 changes the size of the contacts 14 and 16. The pressing portion 32 is lifted to press the FPC 80 against the contact portion 26 side of the contacts 14 and 16. The shape of the cam portion 54 to be contacted can be rotated between the pressing portion 32 of the contacts 14, 16 and the protruding base 44 of the connection portion 40, and the contact 14, As long as the 16 pressing portions 32 are pushed up and the contact portions 26 of the contacts 14 and 16 come into contact with the connection object (FPC 80) as shown in FIGS. The shape and size of the cam portion 54 in the contacted portion are appropriately designed in consideration of the above.
