Post both sides process a wiring plane respectively, and wiring plane is provided with p-wire junction point, for connecting voltage line end and electric current
Line end, connects matrix mantle fiber connector below cylindrical steel column, matrix mantle fiber connector is connected with convex mantle fiber connector, convex
Insulation handle is connected below mantle fiber connector.
P-wire is reliably connected by described test connecting line point screw with the wiring plane on file face, in test,
Ensure signal normal transmission, test job terminates, and can remove p-wire, be readily transported from file face.
Described matrix mantle fiber connector is the female type connection with interior mantle fiber of steel, and upper surface is welded on file face
Together, lower surface is connected with convex mantle fiber connector by interior threading, plays fixing, support file face, connects convex set
The effect of wire.
Described convex mantle fiber connector is the convex mantle fiber connector of steel, and outer mantle fiber is passed through with matrix mantle fiber even in upper surface
Fitting connects, and lower surface is connected with insulated handle by interior mantle fiber, plays fixation, transition connect matrix mantle fiber connector with exhausted
The effect of edge handle.
Described insulation handle adopts epoxide resin material to make, and upper surface is connected with convex mantle fiber connector by outer mantle fiber
Connect, have the characteristics that light, be on the one hand easy to operate, on the other hand play insulating effect.
The utility model has the advantages that：It is provided with file face, be easy to polishing ground connection band iron, make ground connection band iron expose a little portion
The sliding contact surface of light splitting, one tip of top design, replace wire clamp to connect ground connection band iron to press mode, can overcome due to connecing
Ground band iron scribbles the trouble that antirust paint or corrosion are seriously brought, and it can be made easily and efficiently good with test ground connection band iron again
Connect, thus shortening the testing time.
