It is equipped with some ceramic boss, cement obturator exceeds insulative head stringing face, cement obturator is round platform cylinder, cement obturator is stretched
The end face going out groove cavities is small end face, and the end face that cement obturator puts in groove cavities is large end face.
The design principle of the present invention is: ceramic insulation head is made truncated cone-shaped, in small end face recessing, and sets in groove
Put cement obturator, be easy to later stage plug nail, in the cushioning effect due to cement obturator, when inserting nail, will not be right
Ceramic insulation head causes to damage, and in addition insulation nail-plate and cement obturator form clamp structure, using the friction of cement obturator
The enough big characteristic of power, the electric wire after clamping is not easily moveable.The mounting means of said structure is very simple, by nail and insulated hanger
The molectron of plate is placed into above cement obturator, and electric wire is placed between them, directly with hammer, nail is hammered into cement and fills out
Fill internal.
Groove cavities are round platform connected in star, and groove cavities bottom surface is provided with some ceramic boss, and cement obturator exceeds absolutely
Edge headstock line face, cement obturator is round platform cylinder, and the end face that cement obturator stretches out groove cavities is small end face, and cement is filled out
Fill body put in groove cavities end face be large end face.
Said structure, can prevent cement obturator from coming off in groove cavities, aborning, add one in mixed mud
Quantitative extender, not dry mixed mud is filled in groove cavities, treats that cement obturator is naturally combined with ceramic boss,
Ceramic boss extends to inside cement obturator, and cement obturator self-assembling formation round platform cylinder, after such cement obturator mummification
Would not come off.
Preferably, cement obturator exceeds insulative head stringing face 1cm to 2cm.It is easy to clamp electric wire.
Preferably, insulated hanger plate face is provided with arc groove to the one side of cement obturator, and wire is stuck in arc groove
Interior.It is easy to clamp electric wire.
Preferably, cement obturator is cuboid or polygon cylinder.Best mode is that cement obturator is arranged to five
Angle star, so will not make cement obturator come off.
Preferably, the number of nail is 4,2 left sides being located at wire, and 2 are located on the right side of wire.
It is an advantage of the current invention that: structure is simple, and low cost is simple and quick, can effectively solve security performance
The problem of difference.
