Since the same connector cap 52 can be used for the base portions 5 and 18 of the female and female connectors, only the cap 52 of one connector will be described.
図 5、 6に示すように、 コネクタキャップ 5 2は 4個の一体脚部 5 6を備えた テーブル部 5 4を含み、 それぞれの脚部は、 ォス、 メスコネクタのべ一ス部 5、 1 8の後方部 1 0、 4 2にそれぞれ備えられたくぼみ 6 0と嚙み合うべく調整さ れた戻り止め部 5 8を備える。 テ一ブル部 5 4の裏面 6 2には直線状に並んだ 3 個の部分 ¾形ドーム 6 4が備えられており、 その並びの最後に主突起 6 6が備え ちれている。 主突起 6 6はドーム 6 4を越えて （すなわちより高く） 突出するこ とに留意されたい。  As shown in FIGS. 5 and 6, the connector cap 52 includes a table portion 54 having four integral legs 56, each of which has a base portion 5 for female and female connectors. It has a detent 58 adapted to mate with the recesses 60 provided in the rear portions 10, 42 of 18. The rear surface 62 of the table portion 54 has three linear domes 64 arranged in a straight line, and a main projection 66 at the end of the arrangement. Note that the main projection 66 projects beyond the dome 64 (ie, higher).
図 7 ( a ) に、 コネクタキャップ部 5 2が接続されたォスコネクタのべ一ス部 5を含むォスコネクタ 4を示す。  FIG. 7A shows the male connector 4 including the male connector base 5 to which the connector cap 52 is connected.

ここでコネクタ 4、 6の動作と使用法を述べる。  Here, the operation and usage of connectors 4 and 6 are described.
コネクタ 4、 6は信号、 特に光信号を搬送する多種類のケーブルでの使用に適 している。 このようなケーブルには、 可撓性のプラスチック光ファイバ一 ( P 0 F ) ケーブルがある。 コネクタ 4、 6は例えば、 日本の三菱レイヨン社から商品 番号 G H N F 4 0 1等で販売されている P O Fでの使用に適している。  Connectors 4 and 6 are suitable for use with many types of cables that carry signals, especially optical signals. Such cables include flexible plastic optical fiber (P0F) cables. The connectors 4 and 6 are suitable for use in, for example, the POF sold by Mitsubishi Rayon Co., Ltd. under the product number GHNF401.
ォスコネクタ 4の使用法を最初に述べる。 使用にあたって、 ケーブルを後方部 から内腔 2 2を通して前面 3 8から突き出るまで押す。 ケーブルは次に溝 2 4の 中に押し込められる。 溝 2 4は上述のようにケーブルを正弦曲線を基本とする交 番経路に従わせ、 それによりケーブルを掴みやすくする。 次にケーブルがドーム 6 4と主突起 6 6に掴まれるようにコネクタキャップ 5 2が後方部 1 0の上にか ぶせて接続される。 主突起 6 6はドーム 6 4を越えて突出するため、 主突起 6 6 はドーム 6 4より前にケーブルを掴んで主安定点 （アンカーポイント） を与える。 結果的に、 溝 2 4内でケーブルが如何に蠕動 （時間の経過とともに次第に生じる が） しても、 内腔 2 2の中でのケーブルの位置を変えず、 従ってケ一ブルの終端 は前面 3 8と同じ高さであり続けるか （後述のケーブルのトリミングの後に） 少 なくとも前面 3 8との関係で一定の位置を占めることができる。 First, the usage of the connector 4 will be described. In use, push the cable from the back until it protrudes from the front 38 through the lumen 22. The cable is then pushed into groove 24. The grooves 24 allow the cable to follow an alternating path based on a sinusoidal curve as described above, thereby making it easier to grasp the cable. Next, the connector cap 52 is connected over the rear portion 10 so that the cable is gripped by the dome 64 and the main projection 66. Since the main projection 6 6 projects beyond the dome 6 4, the main projection 6 6 Grabs the cable before the dome 6 4 to give the main stability point (anchor point). As a result, no matter how peristaltic the cable is in the groove 24 (although it gradually develops over time), it does not change the position of the cable in the lumen 22 and therefore the cable ends at the front Should it remain at the same height as 38? (After the cable trimming described below), it can at least occupy a certain position in relation to the front 38.
コネクタキャップ部 5 2により一旦ケーブルが所定の位置に固定されたら、 ケ —ブル前方の終端を前面 3 8と同じ高さになるようにトリミングしてよい。 図 3 に見られるように、 ケーブルをトリミングするためにガイ ド突起 3 6の間に刃を 通せるように 2個のガイ ド突起 3 6の間にスペースがおかれる。  Once the cable is fixed in place by the connector cap 52, the front end of the cable may be trimmed to be flush with the front surface 38. As can be seen in FIG. 3, there is a space between the two guide lugs 36 to allow the blade to pass between the guide lugs 36 to trim the cable.
溝 2 4の形状、 およびドーム 6 4の丸い特性により、 ケーブルの表面に食い込 む必要なく、 またケーブルに他のいかなる損傷も起こさずにケーブルを所定の位 置に保持することが保証される。 ファイバー直径が約 1 ミリメ一トルでポリェチ レンジャケッ 卜の外径が約 2 . 2ミリメ一トルである P 0 Fケーブルに対して、 ビーク間振幅が約 0 . 5ミリメ一トルである正弦曲線の経路にケーブルが従うよ うに、 溝 2 4の寸法がとられている。  The shape of the groove 24 and the round nature of the dome 64 guarantee that the cable will stay in place without having to dig into the surface of the cable and cause any other damage to the cable . A sinusoidal path with a beak amplitude of about 0.5 millimeters for a P0F cable with a fiber diameter of about 1 millimeter and an outer diameter of the polyethylene jacket of about 2.2 millimeters The dimensions of the grooves 24 are such that the cable follows.
図 7 ( b ) に示すメスコネクタ 6は、 図 7 ( a ) のォスコネクタ 4と同様に動 作し、 使用される。 コネクタキャップ 5 2を接続することにより一旦ケ一ブルが 所定の位置に固定されたら、 ケーブル前方の終端をメスコネクタのベース部 1 8 の前面 4 8と同じ高さになるようにトリミングしてよい。  The female connector 6 shown in FIG. 7 (b) operates and is used in the same manner as the female connector 4 of FIG. 7 (a). Once the cable is fixed in place by connecting the connector cap 52, the front end of the cable may be trimmed so that it is flush with the front surface 48 of the female connector base 18 .
図 1に示すように、 ォス、 メスコネクタ 4、 6は、 接続アーム 1 2上の戻り止 め部 1 4がメスコネクタペース部 1 8上のくぼみ 1 6と嚙み合うように互いに押 し込んで接続される。 2本のケーブルが同心円状に接続されることを確実にする ため、 ガイ ド突起 3 6がガイ ド溝 5 0内に配置されている。 P O Fケーブルの場 合、 完全に嚙み合っている時にケーブルの終端間に適当な隙間が残るように、 ガ イ ド突起 3 6とガイ ド溝 5◦の寸法が決められている。  As shown in FIG. 1, the female and female connectors 4 and 6 are pushed together so that the detents 14 on the connecting arm 12 engage the recesses 16 on the female connector pace 18. Connected. Guide protrusions 36 are located in guide grooves 50 to ensure that the two cables are connected concentrically. In the case of a POF cable, the dimensions of the guide projection 36 and the guide groove 5◦ are determined so that an appropriate gap remains between the ends of the cable when the cable is completely engaged.
コネクタは道具を全く使用することなく操作できる。 コネクタはまた、 分極化 されておらず、 ケーブル軸の回りに 1 8 0 ° 回転させられても機能を果たす。 産業上の利用可能性 The connector can be operated without any tools. The connector is also non-polarized and will function even if rotated 180 ° around the cable axis. Industrial applicability
