The two ends of the lead 2 are respectively connected with a plug 1 and a socket 3. The plug 1 and the socket 3 are columnar. The figures and description of the present specification exemplify a cylindrical plug 1 and a cylindrical socket 3. The plug 1 is a cylindrical cavity structure, one end of the cylindrical cavity is provided with a plug wire connecting hole, and one end of the wire 2 is inserted into the wire connecting hole. The plug 1 is provided with a plurality of inserting pieces 11. The number of the insertion pieces 11 is equal to the number of the insulated wires in the lead wires 2, and the figure and the description of the specification take four insertion pieces 11 as an example. One end of the inserting piece 11 is positioned in the cylindrical cavity of the plug 1 and is connected with an insulating wire end of the wire 2 inserted into the inner end of the cylindrical cavity of the plug 1. The other end of the inserting piece 11 extends out of the cylindrical cavity of the plug 1, and the plug 1 is protruded out of the outer surface of the cylindrical end face corresponding to the plug lead connecting hole. The section of the inserting piece 11 is arc-shaped. The arcs of the four insertion pieces 11 are positioned on a circle which takes the center of the end surface of the cylinder of the plug 1 as the center of a circle. Locking tabs 111 (one shown) are attached to the sides of at least one of the tabs 11. The locking piece 111 is strip-shaped. The locking piece 111 is fixed with the side of the inserting piece 11. The locking piece 111 and the inserting piece 11 are smoothly connected into a whole. The end face of the locking piece 111 is flush with or has a height equal to that of the insertion piece 11, and the other end of the locking piece 111 must be shorter than the insertion piece 11. The section of the locking piece 111 connected with the inserting piece 11 is L-shaped. The socket 3 is a cylindrical cavity structure. One end of the cylindrical cavity of the socket 3 is provided with a plug wire connecting hole, and the other end of the wire 2 is inserted into the plug wire connecting hole. The receptacle 3 is connected with a barrel-shaped cover 32. The cover 32 is located at the other end of the socket 3 where the plug wire connecting hole is formed, and is a part of the cylindrical cavity, and the bottom of the cover 32 is the end face of the cylindrical cavity of the socket 3. The socket 3 is provided with a plurality of insertion holes 321. The receptacle 321 is located on the bottom surface of the casing 32, i.e., the receptacle 321 is located on the bottom of the barrel of the casing 32. The number of the insertion holes 321 is equal to the number of the insulated wires in the wire 2, and there are four. The insertion hole 321 is circular arc shaped. At least one of the insertion holes 321 is provided with locking holes 322 (one shown). The locking hole 22 is rectangular and is connected to one end of the insertion hole 321. The locking hole 322 communicates with the insertion hole 321 in an L-shape. The arcs of the four insertion holes 321 are located on a circle centered on the center of the bottom of the cover 32. The circle has the same diameter as the circle on which the four insertion pieces 11 are arranged. The plug 1 is attached to the end face of the socket 3, and the jack 321 is positioned at the same position as the insert 11, the locking plate 111 and the lock hole 322; the section of the insertion hole 321 is the same as that of the insertion sheet 11, and the section of the locking hole 322 is the same as that of the locking sheet 111. The socket 3 is provided with pins 31 in a housing 32. The number of the pins 31 is equal to the number of the jacks 321, and one pin 31 is correspondingly arranged in one jack 321. The pin 31 has a V-shape and opens toward the insertion hole 321. The open opposite ends of the pins 31 are connected to insulated terminals of the conductors 2 inserted into the cylindrical cavities of the sockets 3.

When connecting, two hands respectively hold the plug 1 with one conductive wire and the socket 3 with the other conductive wire, insert the insert 11 of the plug 1 into the insertion hole 321 of the socket 3, and simultaneously insert the locking plate 111 of the plug 1 into the locking hole 322, as shown in fig. 7. When the locking tab 111 is fully inserted into the locking hole 322, the insert 11 is inserted into the pin 31. The plug 1 and the socket 3 are rotated in opposite directions as indicated by arrows in the figure. When the rotation is not possible any more, i.e. the locking piece 111 is blocked by the side of the pin 31, as shown in fig. 6, the rotation is stopped and the connection is completed. When the conductive wire of the connecting plug 1 and the conductive wire of the connecting socket 3 are under tension, the end face of the locking piece 111 is pressed against the bottom of the cover 32, as shown in fig. 5, the connected conductive wires cannot be disconnected.
