　しかし、上述のような従来の位置決め手段を設けたコネクタにおいては、位置決め用の突起が位置決め溝に進入するように、プラグとソケットとを位置合わせするのが面倒である。
　特に、プラグとソケットとのいずれか一方が、電子機器の裏面等に取り付けられている場合には、接続個所を視認できず、それらの接続作業を手探りで行わなければならないことが多く、そのような場合には、接続作業が極めて困難になる。 However, in the connector provided with the conventional positioning means as described above, it is troublesome to align the plug and the socket so that the positioning projection enters the positioning groove.
In particular, when either one of the plug and the socket is attached to the back surface of an electronic device or the like, it is often impossible to visually recognize the connection portion, and it is often necessary to perform a connection work of them. In such a case, connection work becomes extremely difficult.
　本発明は、従来の技術が有する上記のような問題点に鑑み、プラグを、その向きを気にすることなく、ソケットに差し込むだけで、それらの内部のプラグ本体とソケット本体とが自動的に位置決めされて、複数の接続手段の接続が適正になされるようにした、構造が簡単なコネクタを提供することを目的としている。 In view of the above-mentioned problems of the conventional technology, the present invention automatically inserts plugs into sockets without worrying about the orientation of the plugs, and the internal plug body and socket body are automatically connected. It is an object of the present invention to provide a connector having a simple structure which is positioned so that a plurality of connecting means are properly connected.

In contact with each other, the plug body and the socket body are rotated relatively to form an inclined cam surface that is positioned in the rotational direction around the central axis.
　また、プラグ本体４におけるピン１９と受け部材２０、およびソケット本体６におけるピン４０と受け部材４１とは、プラグ本体４とソケット本体６との対向部に設けられ、両本体が中心軸線回りの回転方向に位置決めされたとき、互いに接触するようにした電気的な接続手段をなしている。 Further, the pin 19 and the receiving member 20 in the plug main body 4 and the pin 40 and the receiving member 41 in the socket main body 6 are provided at the opposed portions of the plug main body 4 and the socket main body 6, and both main bodies rotate around the central axis. When positioned in the direction, it is an electrical connection means that comes into contact with each other.
　このコネクタにおいては、プラグケース３を把持して、プラグ本体４の筒部１３が、ソケット２におけるソケットケース５と傾斜カムブロック３６との間の空間内に進入するように、プラグ本体４を、電子機器等のケースに固定されたソケット２に差し込むと、プラグ本体４とソケット本体６とがそれらの中心軸線回りの回転方向の正規の位置において向き合っていない限り、プラグ本体４における傾斜カム面１６の第１傾斜面１６ｂと、ソケット本体６における傾斜カム面３７の第１傾斜面３７ｂとの少なくとも一部が互いに当接した後、それらの傾斜に沿って摺動することにより、プラグ本体４がソケットケース５内において中心軸線回りに回転させられる。 In this connector, the plug body 4 is gripped so that the tubular portion 13 of the plug body 4 enters the space between the socket case 5 and the inclined cam block 36 in the socket 2. When the plug body 4 and the socket body 6 are inserted into the socket 2 fixed to a case of an electronic device or the like, the inclined cam surface 16 of the plug body 4 is not provided unless the plug body 4 and the socket body 6 face each other at regular positions in the rotational direction around the central axis. After the first inclined surface 16b and the first inclined surface 37b of the inclined cam surface 37 of the socket body 6 are in contact with each other, the plug body 4 is slid along these inclinations so that the plug body 4 is The socket case 5 is rotated around the central axis.
　このとき、プラグ本体４は、プラグケース３内においても相対的に回転できるので、把持したプラグケース３がつれ回されることはなく、把持したプラグケース３を把持したまま、プラグ１をソケット２にさらに差し込むことができる。 At this time, since the plug body 4 can be rotated relatively in the plug case 3, the gripped plug case 3 is not swung around, and the plug 1 is inserted into the socket 2 while holding the gripped plug case 3. Can be further plugged into.
　プラグ本体４が、ソケット本体６の中心軸線回りの回転方向における正規の位置まで回転させられると、それ以後は、その位置関係を保ったまま、プラグ本体４における傾斜カム面１６の段差面１６ａと、ソケット本体６における傾斜カム面３７の段差面３７ａとが互いに摺接しつつ、プラグ１はソケット２にさらに差し込まれ、プラグ本体４のピン１９は、ソケット本体６におけるピン挿入孔３８を通って、受け部材４１に、またソケット本体６のピン４０は、プラグ本体４におけるピン挿入孔１７を通って、受け部材２０にそれぞれ挿入され、電気的な接続がなされる。 When the plug body 4 is rotated to a normal position in the rotational direction around the central axis of the socket body 6, the stepped surface 16a of the inclined cam surface 16 in the plug body 4 is maintained with the positional relationship thereafter. The plug 1 is further inserted into the socket 2 while the stepped surface 37a of the inclined cam surface 37 in the socket body 6 is in sliding contact with each other, and the pin 19 of the plug body 4 passes through the pin insertion hole 38 in the socket body 6, The pins 40 of the socket body 6 and the socket body 6 are inserted into the receiving member 20 through the pin insertion holes 17 in the plug body 4 to be electrically connected.
　プラグ１がソケット２に完全に差し込まれると、抜止め部材２３の係止爪２６が、ソケットケース５における被係止部３４に係合して、プラグ１はソケット２から抜け止めされる。

When the locking claw 26 is engaged with the locked portion 34 in the socket case 5, the tip of the inwardly inclined portion 11 in the plug case 3 comes into contact with the convex portion 28 in the retaining member 23, thereby locking The claw 26 can be surely pushed into the locked portion 34.
　プラグ１がソケット２に完全に差し込まれたとき、プラグ本体４の筒部１３とソケット本体６の傾斜カムブロック３６との接触部分、特に、傾斜カム面１６、３７同士が密接または圧接するようにしておくと、ピン１９、４０と受け部材４１、２０との接触部分の防水を図ることができる。 When the plug 1 is completely inserted into the socket 2, the contact portion between the cylindrical portion 13 of the plug body 4 and the inclined cam block 36 of the socket body 6, particularly the inclined cam surfaces 16 and 37 are brought into close contact or pressure contact with each other.

Since it is done appropriately, even if the connection location between the plug 1 and the socket 2 is not visible, the connection work can be performed easily and quickly even by groping.
　また、筒部１３内において、プラグ本体４の傾斜カム面１６とソケット本体６の傾斜カム面３７とが摺接するようにしてあるので、両傾斜カム面１６、３７の摺接面が、筒部１３によって防護され、両傾斜カム面１６、３７間に異物が混入するのが防止されるだけでなく、筒部１３によって、相手方の本体が進入するのが案内され、プラグ１とソケット２との差し込み作業を円滑に行うことができる。 Further, since the inclined cam surface 16 of the plug main body 4 and the inclined cam surface 37 of the socket main body 6 are in sliding contact with each other in the cylindrical portion 13, the sliding contact surfaces of both the inclined cam surfaces 16, 37 are the cylindrical portion. 13, and not only foreign matter is prevented from entering between the inclined cam surfaces 16 and 37, but the other body is guided by the cylindrical portion 13, so that the plug 1 and the socket 2 Insertion work can be performed smoothly.
　さらに、プラグ本体４とソケット本体６との対向部に、それらの中心軸線と平行な段差面１６ａ、３７ａを設け、プラグ本体４とソケット本体６とが、中心軸線回りの回転方向に位置決めされた後、この段差面１６ａ、３７ａ同士が互いに摺接して、プラグ本体４とソケット本体６とが、互いに中心軸線方向に接近しうるようにしてあるので、プラグ１とソケット２との軸線方向の差し込みストロークを大として、電気的な接続手段の接触面積を増大させることができるとともに、段差面１６ａ、３７ａ同士の摺接により、プラグ本体４とソケット本体６とは、中心軸線回りの回転方向に対して強固に結合され、接続部の強度を大とすることができる。 In addition, stepped surfaces 16a and 37a parallel to the central axis of the plug main body 4 and the socket main body 6 are provided at the opposing portions, and the plug main body 4 and the socket main body 6 are positioned in the rotational direction around the central axis. Thereafter, the step surfaces 16a and 37a are in sliding contact with each other so that the plug main body 4 and the socket main body 6 can approach each other in the central axis direction, so that the plug 1 and the socket 2 are inserted in the axial direction. By increasing the stroke, the contact area of the electrical connecting means can be increased, and the plug body 4 and the socket body 6 can move relative to the rotational direction around the central axis by sliding contact between the step surfaces 16a and 37a. And the strength of the connecting portion can be increased.
