Embodiment
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
The electric energy quality monitoring switching device of the present invention, including male plug 1 and female plug 2, the structure of male plug 1 is as shown in figure 1, male plug
1 includes metal shaft 11, and the entirety of metal shaft 11 is in round table-like, and metal shaft 11 is using the strong metal material of conductive capability.Metal shaft 11
Bottom be provided with a plug wire hole 12, the side of metal shaft 11 is provided with counter sink 13, and counter sink 13 penetrates plug wire hole 12, plug wire hole 12
Interior pluggable conductor wire, and fastening bolt is screwed into counter sink 13, so as to which conductor wire is fixed in male plug 1.
The top of the metal shaft 11 is provided with connecting pole 14, and connecting pole 14 is insulator, and the top of connecting pole 14, which is provided with, to be fixed
Bar 15, the outside car of fix bar 15 have screw thread.
For the structure of female plug 2 as shown in Fig. 2 the entirety of female plug 2 is in cylinder, female plug 2 is interior to be provided with a connecting hole 21.
In order that male plug 1 and female plug 2 are more combined closely, the external diameter of the bottom of metal shaft 11 is equal to the connecting hole 21 of female plug 2
Diameter, the external diameter on the top of metal shaft 11 is less than the diameter of the connecting hole 21 of female plug 2, as shown in Figure 3,4, when the top of metal shaft 11
Connecting hole 21 is inserted into from one end of female plug 2 and is stretched out from the other end of connecting hole 21 of female plug 2, the top of metal shaft 11 and connection
The top in hole 21 is generally aligned in the same plane, and now fix bar 15 and connecting pole 14 are respectively positioned on the outside of connecting hole 21, to fix bar 15
