Connector
A plug includes a plug main body, a connection sleeve, and a connection ring. A socket includes a socket main body and a socket holder. An insertion member of the socket main body is fitted to an engagement concave of the plug main body. An engaging projection of the socket holder is fitted to one end of a circular-arc slit of the connection ring. The connection ring is rotated to relatively shift the engaging projection along the circular-arc slit, and the engaging projection is positioned and locked at the other end of the circular-arc slit.
1. A connector for coaxially connecting connection lines by connecting a plug one end of which connects with one of the connection lines and a socket one end of which connects with the other of the connection lines as one piece, wherein:
the plug includes (a) a plug main body one end of which connects with the connection line and the other end of which has an engagement concave, (b) a connection sleeve as a cylindrical component rotatably attached to the outer surface of the plug main body with separation prevented, a guide member being provided on the outer surface at one end of the connection sleeve, and a male screw being formed on the outer surface at the other end of the connection sleeve, and (c) a connection ring as a cylindrical component on the outer surface of which a circular-arc slit is formed, the connection ring coaxially accommodating the connection sleeve with separation prevented, and the connection ring being assembled to the connection sleeve to be rotatable with the connection sleeve as one piece;
the socket includes (a) a socket main body one end of which connects with the connection line and the other end of which has a projecting insertion member, and (b) a socket holder as a cylindrical component which coaxially accommodates the socket main body with separation prevented, an engaging projection being provided on the outer surface of the socket holder close to the opening edge thereof, a guide member being provided on the inner surface of the socket holder opposed to the socket main body close to the opening edge of the socket holder, and a female screw being formed at the back of the guide member; and
the insertion member of the socket main body is fitted to the engagement concave of the plug main body, the engaging projection of the socket holder is fitted to one end of the circular-arc slit of the connection ring, and the engaging projection is relatively shifted along the circular-arc slit to be positioned and locked at the other end of the circular-arc slit.
2. A connector as set forth in claim 1 , wherein the connection lines are electric cables.
3. A connector as set forth in claim 1 , wherein the socket holder is rotatably attached to the socket main body.
4. A connector as set forth in claim 3 , wherein the connection lines are electric cables.
5. A connector as set forth in claim 1 , wherein:
a screw socket included in the connector has a socket holder as a cylindrical component which coaxially accommodates a socket main body with separation prevented and on the inner surface of which a female screw is formed opposed to the socket main body;
an insertion member of the socket main body is fitted to the engaging concave of the plug main body; and
the female screw of the screw socket is fitted to the male screw of the connection sleeve so as to connect the screw socket to the plug as one piece.
6. A connector as set forth in claim 5 , wherein the connection lines are electric cables.
7. A connector as set forth in claim 1 , wherein:
a screw plug included in the connector has a plug holder as a cylindrical component which is rotatably attached to the outer surface of a plug main body with separation prevented and on the outer surface of which a male screw is formed at the tip of the plug holder;
the insertion member of the socket main body is fitted to an engagement concave of the plug main body; and
the male screw of the screw plug is fitted to the female screw of the socket holder so as to connect the screw plug to the socket as one piece.
8. A connector as set forth in claim 7 , wherein the connection lines are electric cables.
9. A connector as set forth in claim 3 , wherein:
a screw plug included in the connector has a plug holder as a cylindrical component which is rotatably attached to the outer surface of a plug main body with separation prevented and on the outer surface of which a male screw is formed at the tip of the plug holder;
the insertion member of the socket main body is fitted to an engagement concave of the plug main body; and
the male screw of the screw plug is fitted to the female screw of the socket holder so as to connect the screw plug to the socket as one piece.
10. A connector as set forth in claim 9 , wherein the connection lines are electric cables.
