Separately four sidewalls of described box body are respectively arranged the preformed hole described in; Also all preformed hole can be set eight sidewalls, think that electric wire is worn connection box from all directions and provided convenient.
The diapire of described box body is arranged the preformed hole described in, the preformed hole in box portion bottom wall can supply lines longitudinally through box body.
The reserved baffle plate identical with preformed hole shape is connected with by being interrupted block gap in described each preformed hole; To fracture a fault block by pressing reserved baffle plate, reserved baffle plate can be removed, remove reserved baffle plate blocking preformed hole, so that by electric wire through preformed hole.
Described limit convex is along being above arranged with two hangers to sidewall evagination, and each hangers is provided with one for the screw of connecting screw; Panel for connecting light fixture is fastened on box body by screw and screw.
Described box side wall internal fixtion two reference columns, each reference column is provided with the location hole that can insert for panel alignment pin; Panel is inserted by the location hole on alignment pin and reference column and is drawn location, to make connecting hole rapid-aligning on the upper screw of hangers and panel, so that panel is located by connecting on box body by screw.
Under described box side wall, the clamped card of evagination is along being provided with some breach; Block along upper breach can card along with concrete in conjunction with time more closely, make the pre-buried bonding strength be embedded in concrete of box body larger.
The shape of described breach is V-arrangement, U-shaped or trapezoidal, and breach of the present utility model preferentially adopts V-shaped part.
The beneficial effects of the utility model are: box body eight side casting concretes and after solidifying, the concrete of box body surrounding snaps in the annular groove between limit convex edge and clamped card edge, clamped card is along forming clamping with concrete, box body cannot be got loose by pre-buried being fixed in concrete firmly, to guarantee that switch panel or socket panel are installed safely and Electrical Safety; And box body can be installed and fix two switches or socket panel, pre-buried box body and use box body all very convenient.

Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Embodiment one (clamped card does not arrange breach along upper).
A kind of built-in type terminal box as shown in FIG. 1 to 3, comprise one for building the box body 10 be embedded in ceiling concrete, box body 10 of the present utility model is eight prismatic box bodys, eight sidewalls 11 of eight prismatic box bodys 10 and diapire 12 are provided with the preformed hole 13 that supply lines passes, wherein: separately four sidewalls 11 of box body 10 respectively arrange a preformed hole 13, the diapire 12 of box body 10 is arranged a preformed hole 13, in each preformed hole 13 by between fault block 15 interval be connected with the reserved baffle plate 14 identical with preformed hole 13 shape, to fracture a fault block 15 by pressing reserved baffle plate 14, reserved baffle plate 14 can be removed, remove blocking of reserved baffle plate 14 pairs of preformed holes 13, so that by electric wire through preformed hole 13, the sidewall 11 of box body 10 hoop is upper and lower have the limit convex that protrudes outside sidewall along 16, clamped card along 17, the limit convex of whole circle forms an annular groove 18 that can embed for concrete along the clamped card of 16 and whole circle between 17.
As depicted in figs. 1 and 2, limit convex is along being arranged with two hangers 19 to sidewall 11 evagination on 16, and each hangers 19 is provided with one for the screw 191 of connecting screw, is fastened on box body 10 for the panel connecting light fixture by screw and screw 191; Box body 10 sidewall 11 internal fixtion two reference columns 20, each reference column 20 is provided with the location hole 201 that can insert for panel alignment pin, panel is inserted by the location hole 201 on alignment pin and reference column 20 and is drawn location, to make upper screw 191 and the connecting hole rapid-aligning on panel of hangers 19, so that panel is located by connecting on box body 10 by screw.
As shown in figures 1 and 3, by the diapire 12 of box body 10 of the present utility model upwards, box body 10 Open Side Down ground arrange on the ceiling, then at box body 10 side casting concrete, casting concrete solidifies in the annular groove 18 of rear embedding box body 10 sidewall 11, limit convex is pressed on ceiling slab face along 16, and clamped card laterally embeds concrete clampings along 17, makes box body 10 cannot from extracting concrete ceiling downwards; Box body 10 is fixed in concrete and cannot gets loose by pre-buried inlaying firmly, to guarantee that switch panel or socket panel are installed safely and Electrical Safety; By in the utility model firmly fixing concrete on the ceiling, and be adjacent to concrete due to eight sidewalls 11 of eight prismatic box bodys 10 of the present utility model, it is in conjunction with great efforts, and therefore the utility model box body 10 can bear the pulling force of pendent lamp.
Embodiment two (clamped convex edge arranges breach).
