In the second embodiment shown in fig. 4 and 10, three second jacks 14 corresponding to the ground wire and the two live wires one by one and a third jack 8 corresponding to the ground wire are arranged in the plug 3, the three second jacks 14 and the third jack 8 correspond to the four first jacks 5 one by one, the second jack 14 is internally provided with a clamping copper sheet 35, the third jack 8 is internally provided with a grounding copper sheet 36, one end of the clamping copper sheet 35 is located in the second jack 14, the other end of the clamping copper sheet 35 is located outside the second jack 14 and is in a circular ring shape, one end of the grounding copper sheet 36 is located in the third jack 8, the other end of the grounding copper sheet 36 is located outside the third jack 8, as shown in fig. 11, the two live wires and the zero wires are detachably connected with one ends of the three clamping copper sheets 35 located outside the first jack 5 respectively in the same connection mode, and the ground wire is detachably connected with one.

As shown in fig. 4 and 12, a cylinder 37 is arranged in one end of the clamping copper sheet 35 located outside the second insertion hole 14, the outer side of the cylinder 37 is in threaded connection with the clamping copper sheet 35, a plurality of clamping blocks 34 are arranged on the inner side of the cylinder 37, the plurality of clamping blocks 34 correspond to each other with the central axis of the cylinder 37 as the center, one end of each clamping block 34 is fixedly connected with the inner side of the cylinder 37 and is far away from the center of the cylinder 37, the other ends of the plurality of clamping blocks 34 are close to the center of the cylinder 37 and form a circular ring shape, and the inner diameter of each clamping block is smaller than the diameter of.

In the first embodiment, the plug 3 is provided with pins 15 so that the plug 3 can be connected with an external power socket in the form of a plug. The core wires 9 in the electric wire are clamped and positioned by two groups of clamping devices 16 which are symmetrical left and right so as to be connected with the corresponding pins 15, and the core wires 9 are convenient to detach and mount. The connecting block 18 and the elastic sheet 19 are made of metal copper, so that when the pin 15 is connected with an external power socket, the core wire 9 can be conveniently conducted with the pin 15 through the elastic sheet 19 to conduct a circuit; when installing the core wire 9, an operator holds the sliding base 20 to move towards one side of the connecting block 18, at this time, under the action of the first connecting rod 25 and the second connecting rod 26, the rotating shaft 27 drives the middle part of the elastic sheet 19 to move outwards through the connecting shaft 28, so that the middle part of the elastic sheet 19 protrudes outwards to increase the gap between the two elastic sheets 19, and the core wire 9 can easily pass through and be installed between the two elastic sheets 19; when the core wire 9 is positioned in the gap, an operator only needs to loosen the sliding seat 20, the sliding seat 20 is reset under the action of the first connecting rod 25, the second connecting rod 26 and the torsion spring, and the two elastic sheets 19 are also reset simultaneously and clamp the core wire 9, so that the connection between the core wire 9 and the corresponding pin 15 is completed; then the sliding seat 20 is inserted into the limiting base 17, and the limiting block 30 limits the length direction of the clamping device 16 to prevent the pin 15 from displacing when being plugged into or pulled out of an external power socket; when the pin 15 is inserted into the external power socket, the slide base 20 acts on the stopper 30, and the force applied to the pin 15 at this time makes the first connecting rod 25, the second connecting rod 26 and the rotating shaft 27 drive the middle portions of the elastic pieces 19 to separate from each other through the connecting shaft 28, so that the core wire 9 is easily separated, and the guide block 32 on the limiting plate 31 acts on the corresponding convex plate 29 to limit the width direction of the clamping device 16, so as to prevent the core wire 9 from separating, and enable the core wire to be normally used.

In the second embodiment, the connector 3 is provided with the clamping copper sheet 35 and the grounding copper sheet 36, so that the connector 3 is connected with an external power plug in a socket manner. When installing the zero line or the live line, an operator inserts the core wire 9 into one end of the clamping copper sheet 35, which is positioned outside the second insertion hole 14, and then rotates the cylinder body 37, so that the cylinder body 37 approaches the core wire 9, and the core wire 9 moves from one end of the clamping blocks 34 to the other end and is positioned, and the installation is convenient and rapid; the inner diameter of one end of the clamping block 34 close to the center of the cylinder 37 is smaller than that of the core wire 9, so that the core wire 9 can be clamped and positioned conveniently, and the core wire 9 is connected stably; the materials of the barrel body 37 and the clamping block 34 are both metal copper, so that the core wire 9 is conveniently conducted with the circuit of the clamping copper sheet 35 through the clamping block 34 and the barrel body 37 when the socket is connected with an external power plug, and the design is reasonable.
