Rod and tubing joint of multiple orientations containing electrical wiring
View Patent ↗A rod and tubing connection for coupling two or more joints of tubing sections comprises a plug and a socket. The plug has a plurality of splines and the socket has a plurality of receptacles adapted to receive the plurality of splines. The plurality of splines comprises a center spline and a plurality of outer splines configured to allow intermeshing with receptacle splines in a plurality of orientations. A coupling collar is used to secure the tubing joint. The plug is connected to the socket in a four-step process of: positioning the plug and socket in close proximity, aligning the spline and the receptacle, plugging the spline into the receptacle, and then securing the plug and socket together with the coupling collar. The tubing joint may also have a conduit containing a wire for transmitting power and data between the adjoined sections of tubing.
1. An apparatus for joining a first rod section and a second rod section together, comprising:
a plug fixedly engaged to a first rod section proximate end and having a plug center spline, a plurality of outer splines, a plurality of first conduits and a plurality of first connectors;
a socket fixedly engaged to a second rod section distal end and having a socket receptacle, a plurality of socket receptacle splines, a plurality of second conduits, and a plurality of second connectors;
a securing device for securing the plug to the socket;
wherein the plug may be joined to the socket in a plurality of orientations so that, in each of the plurality of orientations, the plug mates with the socket;
wherein a cavity created by the socket receptacle and the plurality of socket receptacle splines is shaped so that the plug center spline and the plurality of plug outer splines will intermesh with the socket receptacle and the socket receptacle splines when the plug and socket are plugged together;
wherein the plurality of plug outer splines and the plurality of socket receptacle splines are coaxially symmetric and have the same dimensions so that an alignment of the plurality of first connectors and the plurality of second connectors can be achieved in the plurality of orientations;
wherein the plug the center spline, the plurality of outer splines, and the plurality of first conduits are of unitary construction with each other; and
wherein the socket, the socket receptacle, the plurality of socket receptacle splines, and the plurality of second conduits are of unitary construction with each other.
2. The apparatus of claim 1 , wherein the securing device is a coupling collar adapted for connecting it to the plug and the socket, the coupling collar initially engaged with the plug.
