Abstract
The utility model discloses a novel DTU shell which comprises a DTU shell body, a front panel and a back panel. The DTU shell body and the front panel and the back panel are respectively provided with a corresponding fixed hole. The DTU shell body and the front panel and the back panel are respectively connected through the corresponding fixed hole. The DTU shell body is internally provided with two clamping grooves used for fixing a PCB. The PCB clamping grooves are respectively arranged at inner walls of the DTU shell body correspondingly. The bottom surface of the DTU shell body is provided with a fixed groove. The front panel is provided with a DB9 port and a 2.54 power socket interface. The back panel is provided with a drawer type SIM card opening, an indicating lamp hole and an antenna SMA hole. The shell body is made of aluminum alloy material. An industrial electronic grey is employed by the shell body whose surface is subjected to sandblasting secondary oxidation processing. The DTU shell body has the advantages of convenient installation, wide application, suitability for large-scale production and low cost.
Description
Technical field
The utility model relates to the technical field of Internet of Things, particularly a kind of novel DTU shell.
Background technology
Common DTU shell is of a great variety in the market, and material is different, differs in size, and profile is different.Not considering of having is fixing, and what have puts into shell with SIM card, changes SIM card very inconvenient, the ferrous material that some employings get rusty easily, and the Power supply interface, the indicator light interface is different especially.Give and install, use and buy accessory and brought very large inconvenience, therefore, there is defective in prior art, needs to improve.
The utility model content
Main purpose of the present utility model is to overcome the deficiencies in the prior art, and a kind of convenient installation is provided, and is widely used, and is fit to large-scale production, novel DTU shell with low cost.
for achieving the above object, the utility model has adopted following technical scheme: a kind of novel DTU shell, comprise the DTU housing, front panel, rear board, described DTU housing respectively with front panel, rear board is provided with corresponding fixing hole, described DTU housing respectively with front panel, rear board connects by fixing hole, be provided with two in described DTU housing and be used for the fixedly draw-in groove of pcb board, described pcb board draw-in groove is slotted in the inwall correspondence of DTU housing respectively, the bottom surface of described DTU housing arranges holddown groove, described front panel is provided with the DB9 mouth, 2.54 power socket interface, described rear board is provided with the drawer type SIM card socket opening, indicator lamp hole, antenna SMA hole, shown in case material be aluminium alloy, described housing adopts the industrial electronic grey, the surface is through the sandblast secondary oxidative treatments,
The height of described pcb board draw-in groove is 2MM, apart from housing bottom 7MM.
The outer wide 6MM of the groove of the holddown groove that the bottom surface of described DTU housing arranges, groove inner width 10MM, degree of depth 3MM;
The long * of SIM card seat opening that described rear board arranges is wide=2.5MM*25MM; The width of described indicator lamp hole is 3.5MM; Described antenna SMA hole width is 6MM.
Beneficial effect with respect to prior art is, the utility model is simple in structure, and pcb board can directly be put into the PCB draw-in groove of housing, has saved fixed screw, has improved installation production efficiency; Front panel power interface and DB9 interface are all industrial accessories commonly used, buy easily cheap; Rear board adopts drawer type SIM card socket, changes card easy, and leaves indicator lamp hole and SMA antenna hole; The housing bottom fluting is convenient to be installed, and shell adopts the industrial electronic grey that bears dirty, and the surface is fine through sandblast secondary oxidative treatments feel, and appearance looks elegant is generous.
