Ground contact includes the rounded portions for locking positioning, the contact part stretching in insulation crust through countersunk head through hole,
Described contact part is positioned at rounded portions side and forms T shape structure, is provided with tapering between rounded portions and contact part
Limited block, described rounded portions, taper limited piece and contact part one are connected, and aforementioned countersunk head through hole connects with isolation
Ground contact is suitable.
Further, described taper limited piece includes the first joint face, the second joint face and taper face, described
One joint face is the end face being connected with rounded portions, and the second joint face is the end face being connected with contact part, institute
Stating taper face is this side of taper limited piece, and wherein the area of the first joint face is more than the face of the second joint face
Long-pending；The medial wall of described countersunk head through hole be with taper limited piece in the suitable conical surface of each taper face.
Further, described rounded portions is raw sheet shape, and this rounded portions offers locking hole, in order to embedding with pyrite
Part is connected.
One countersunk head through hole with tapering medial wall of the Position Design of ground connection in this utility model structure, and
And relate to the most taper limited piece of a tapering boss connecing isolation the upper of grounding contact simultaneously, this is taper limited
The taper face of block is suitable with the conical surface of countersunk head through hole, and such taper fit can maximum depth reduction ground connection be touched
The angular error of flat position；Simultaneously this most novel utilizes two to embedded in two brass inserts to connect for fixing isolation
Ground contact, reaches the purpose of stable installation, reaches to install surely while solving the angular error problem of flat position
Fixed effect, and then the service life of elongate member.
