Below in conjunction with accompanying drawing the utility model is further elaborated.

As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the utility model 10 comprises insulating base 11, axle 12, outer tube 13, the first terminal 14, second terminal 15 and insulator 16.Insulating base 11 is to make with insulating material such as plastic cement.Insulating base 11 is hollow cylindrical, and its inner formation front end is ringent spliced eye 17, and insulating base 11 outer walls bottom convexes with at least one reference column 18.

Axle 12, outer tube 13, the first terminal 14 and second terminal 15 are to make with copper conductive material.Axle 12 is spliced eye 17 inside that are arranged at insulating base 11, and axle 12 front ends form a bigger head 19.This head 19 is to be exposed to spliced eye 17 Inner Front End places, and axle 12 outer wall rear end system ring is set position flange 20.

Outer tube 13 is hollow round tubular, and it is to be sheathed on axle 12 outsides, and outer tube 13 maintains certain spacing with axle 12, uses to form the two poles of the earth separation state.Outer tube 13 outer wall rear end are also encircled and are established a location flange 21.Axle 12 length are greater than outer tube 13 length, so that the locating flange 20 of the head 19 of axle 12 front ends and rear end all is exposed to outer tube 13.
