Embodiment
Describe the present invention below with reference to each execution mode shown in the drawings.But these execution modes do not limit the present invention, and the conversion on the structure that those of ordinary skill in the art makes according to these execution modes, method or the function all is included in protection scope of the present invention.
To shown in Figure 5, an embodiment of the present invention terminal box comprises box body 1, the loam cake 2 that cooperates with box body 1, is contained in terminal module 3 and sealing strip 4 in the box body 1 such as Fig. 1.
Box body 1 comprises diapire 11, upwardly extending sidewall 12 and the host cavity 15 between two side 12 from diapire 11 both sides.Box body 1 further comprises antetheca 13 and the rear wall 14 that connects sidewall 12.Diapire 11 upwards is being provided with the clasp arm 16 that protrudes into host cavity 15 near sidewall 12 places.In the present embodiment, be provided with two clasp arms 16 near each sidewall.Take clasp arm 16 as the boundary, host cavity 15 is divided into the first space 151 and second space 152, the first spaces 151 are the zone line of host cavity 15, hereinafter describes in detail in order to hold terminal board 31(); Second space 152 is the first space 151 two side areas, and namely space between clasp arm 16 and the respective side walls 12 is distributed with vertically and horizontally arranged some reinforcements 18 to strengthen the intensity of box body 1 in second space 152.
Antetheca 13 is provided with projection 132 toward the outer side, and rear wall 14 bottoms are provided with carrier 141, preferably, and carrier 141 semicirculars in shape.
Loam cake 2 is provided with flat main part 21, the autonomous outward extending clinch 22 of body 21 1 ends and autonomous body 21 other ends to the holding part 23 of downward-extension, the periphery of main part 21 is provided with annular groove 211, sealing strip 4 is embedded in the annular groove 211, to play waterproof action after cooperating with box body 1 at loam cake 2.Clinch 22 is positioned at main part 21 belows, and preferably, it is half-cylindrical that clinch 22 is, to match with carrier 141.Holding part 23 is provided with the groove 231 with projection 132 phase clasps in inboard both sides, be provided with opening groove 232 in the centre position.In the assembling process, loam cake 2 relative level face tilt certain angles, make clinch 22 stretch into host cavity 15 and also further be resisted against rear wall 14, particularly, be resisted against the carrier 141 on the rear wall 14, then press down holding part 23, holding part 23 and antetheca 13 are fastened, particularly, the groove 231 on the holding part 23 is interlocked with the projection 132 on the antetheca 13, thus locking loam cake 2.Antetheca 13 is provided with holding block 133 above opening groove 232, when needing dismounting, bottle opener (not shown) from up to down part stretches in the opening groove 232, thereby bottle opener another part is resisted against holding block 133 bottle opener is tilted at an angle, makes things convenient for projection 132 and groove 231 to break away from.Certainly, in other embodiments, also can groove be set at antetheca 13, and at the holding part 23 of loam cake 2 projection be set.
