Erosion, while these material stiffness are larger, in the construction process, are easy mechanically damaged.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides a kind of using graphite material, conduction
It is high-efficient, corrosion resistant graphite grounding body.
The purpose of this utility model is achieved through the following technical solutions: a kind of graphite grounding body title, it includes Y fashioned iron
Piece and ground line；Expanded graphite, the Y fashioned iron piece and the expanded graphite are filled between each corner angle of the Y fashioned iron piece
Extexine be provided with Graphite cloth, Graphite cloth's extexine is provided with wire braid, wire braid extexine
It is provided with conductive rubber；The Y fashioned iron piece end surface offers several through-holes, and the ground line is fastened in through-hole.
Further, the bottom of the graphite grounding body is additionally provided with conductivity ceramics pedestal, and conductivity ceramics base sheath is mounted in

Socket part point is fixed using conducting resinl sealing, and conductivity ceramics pedestal 12 completely cuts off the metal material of protective grounding body bottom-exposed, circle
Column chassis structure facilitates fixed vertically when construction bury.
End surface of the Y fashioned iron piece 1 in the one end connecting with ground line 6 is coated with conductivity ceramics coating, described to connect
Ground wire 6 is the flat steel bar that cross section is rectangle, and the upper end for being grounded 6 is additionally provided with connector 61, and it is solid that screw thread is provided on connector 61
Determine hole.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
