Background technology
The cabinet of the microwave transmission indoor unit device that uses all is to adopt screw that upper cover plate of " ㄇ " type and the base plate spiral shell of " " type are become one admittedly as the cabinet of most of electronic equipments at present; And in this casing, directly be screwed a monoblock printing board PCB.If the user need upgrade or proposes different configurations certain hardware on the printed circuit board, all must adopt under the screw threads demolition of screwdriver with solid cabinet of spiral shell and pcb board, open the chassis cover plate, after again pcb board being taken out from casing, can carry out HardwareUpgring or change configuration.The cabinet of this conventional construction was continued to use many years, did not improve all the time.Because its structural design is unreasonable, cause the operation of product up-gradation or improvement configuration very loaded down with trivial details, complicated, efficient is very low.Therefore, replace in the renewal of development in science and technology and components and parts and to be in today with rapid changepl. never-ending changes and improvements, how the casing structure to this electronic equipment improves or redesigns, and is very necessary, and becomes the new problem that those skilled in the art pay special attention to.
The utility model content
In view of this, the purpose of this utility model provides a kind of microwave transmission indoor unit device, the main feature of this device casing structure is to be provided with a plurality of guide rails in cabinet, so that the printed circuit board (PCB) in the cabinet is resolved into a plurality of functional modules according to its different functions of use, and, each functional module all can be independently, easily along the guide rail plug of sliding, need not to dismantle holding screw, thereby solved the problem of user flexibility updating apparatus hardware configuration preferably with screwdriver.
In order to achieve the above object, the invention provides a kind of microwave transmission indoor unit device, the cabinet of this device includes: the casing, front panel, the printed circuit board (PCB) that are made of upper cover plate and base plate, it is characterized in that: described cabinet also includes: the solid two or more guide rails of spiral shell on base plate, and the hand-screw that is used for the front panel spiral shell is consolidated the installing hole on box bottom; Wherein, slide between the chute of each guide rail and be provided with the printed circuit board (PCB) of one or more functional modules, these printed circuit board (PCB)s become one with the front panel spiral shell of screw and its front side respectively again admittedly; During fitting printed circuit board, directly pass the corresponding window of casing and insert chute between the corresponding guide rail, be fixed on front panel and printed circuit board (PCB) on the casing together by hand-screw again; When need changing certain printed circuit board (PCB) or components and parts wherein, only need directly the hand-screw of the front panel of correspondence is unscrewed, in the lump this front panel and the printed circuit board (PCB) affixed with it are extracted out from casing, change and get final product.
Described front panel has one or more, and its quantity can be corresponding with the quantity of the printed circuit board (PCB) of described functional module.
The functional module of described printed circuit board (PCB) comprises: webmaster module, time division multiplexing module and 1+1 masterslave switchover backup module, wherein the time division multiplexing module of daily need maintenance and 1+1 masterslave switchover backup module fix as one with screw and front panel separately respectively, so that the control circuit moduleization of each functional unit of this device, each module can independently plug, and solves the problem of flexible upgrading hardware configuration preferably.
The width of described printed circuit board (PCB) will and its correspondence position guide rail chute between width constitute and to be slidingly matched.
The material of described guide rail is aluminium alloy or engineering plastics, and this guide rail has two kinds of structures: one-sided chute and bilateral chute.
Characteristics of the present utility model are at the existing problem of current microwave transmission indoor unit device cabinet, a kind of novel casing structure of being made up of casing, guide rail, front panel, hand-screw is provided, its middle guide is separated into three functional circuits such as webmaster module, time division multiplexing module, 1+1 masterslave switchover backup module with the control circuit of box house, realize the splitization of functional module, and making this several functional unit block and front panel is affixed becomes one, each module can independently plug.Like this, when the user need upgrade to equipment, do not need to open cabinet, need can directly hand-screw not unscrewed yet, just corresponding printed circuit board (PCB) be extracted out from casing by any instrument, replace again and go up new functional circuit plate, the conduit that inserts guide rail gets final product, and has simplified the process that product is upgraded greatly, thereby has solved the problem of user flexibility updating apparatus configuration well.
