Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under that premise of not paying creative labor
Embodiment shall fall within the protection scope of the present invention.In the following description, structure and work side of the invention in order to clearly demonstrate
Formula will be described on the basis of attached drawing by many Directional words, but should by "front", "rear", "left", "right",
The Word Understandings such as "upper", "lower" are not construed as word of limitation for convenience of term.
Existing terminal block is as shown in fig. 7, figure label is as follows, terminal block sliding block 21, the lock-screw 22 of connecting terminal,
Slider locking screw 23.
Embodiment 1
The secondary security isolation tool of current terminal shown in Fig. 1-4, including spacing block 1, Yi Jiyong made of three blocks of insulating materials
In the insulating bar 2 for connecting each spacing block 1；The spacing block 1 includes pedestal 3, and is set to 3 one end of pedestal, for obstructing end
The plug division 4 of son row's sliding block；The through-hole 5 passed through for insulating bar 2 is set on the pedestal 3, and the insulating bar 2 rubs with through-hole 5
Engagement, it is ensured that insulating bar 2 will not be automatically disengaged with pedestal 3；The pedestal 3 is arranged in insulating bar 2 by through-hole 5 thereon side by side
On.
In order to improve the convenience of disassembly, on the pedestal, the setting of one end far from plug division 4 is convenient for hand-held lip
