It is straight to be outwards respectively arranged with stretching boss, also, the stretching boss of both sides outwards exceeds mounting post, stretches out boss and inserted sheet sheet
Limited step is formed between body, stretches out in the end face outside of boss and offers anti-skidding band.
As a preferred embodiment, in the pre-buried type Built-in terminal box, the anti-skidding band is " V "-shaped.
As a preferred embodiment, in the pre-buried type Built-in terminal box, in the second sidewall and the 4th side wall
It is provided with least one reinforcing rib.
As a preferred embodiment, in the pre-buried type Built-in terminal box, the reinforcing rib at least three, with
The arranged direction of the mounting post is consistent.
As a preferred embodiment, in the pre-buried type Built-in terminal box, the reinforcing rib is arranged on second sidewall
On the outer surface of the 4th side wall.
The beneficial effects of the utility model are：The utility model is matched with flat head screw by being opened up in mounting post
Mounting hole, also, the inner small and outside big staged jack perpendicular to the mounting hole is opened up in mounting post, and in the jack
Plug metal insert, so as to ensure that the installation site on Built-in terminal box is fixed so that using moderate length screw just
Can be with, installation cost is saved, also, installation is convenient to, and improves installation effectiveness.Further, since staged jack
Outside macropore extends through the side wall of mounting post both sides, moreover, boss is stretched out in the both sides of metal insert outwards exceeds mounting post,
So as to greatly facilitate the dismounting of metal insert.
