Description
Technical field
The present invention relates to a kind of Instrument shell.
Background technology
The housing of instrument is usually by the shell for base plate in installing base plate in wiring board and electronic component, holding, the front panel for button installation and display, formed for the rear board installing input and output terminals; Described middle base plate, front panel and rear board are in released state, make the assembly process more complicated of instrument; Particularly when instrument carries out machine debugging, often need each point signal or the replacing electronic component that stir middle base plate measurement circuitry plate, because middle base plate, front panel and rear board are that Split type structure easily breaks connecting line; Also cannot take out separately base plate in during apparatus guarantee use is on-the-spot in addition, complete machine must be unloaded from control cubicle, very inconvenient.
Summary of the invention
The technical problem to be solved in the present invention is, provides a kind of Instrument shell of new structure, and in this housing, base plate, front panel and rear board are structure as a whole, and facilitates the assembling of instrument, debugging and maintenance.
The technical scheme of technical solution problem is, a kind of Instrument shell comprises support body 10, shell 2, it is characterized in that, described shell is the rectangle box body that two ends have opening, described support body is by middle base plate 4, front panel 3 and rear board 5 are integrally formed, its cross sectional shape is " H " shape, can be inserted in shell from the rear end of shell, the front end of described shell is fixedly connected with the cover body 1 of a shaped as frame, the length of side on inside casing four limit of cover body is less than the length of side on front panel four limit, a left side for the rear end of shell, right side wall is arranged with the draw-in groove 7 of " Γ " font, the fastening block 8 of strip is provided with between draw-in groove, the two ends of fastening block are provided with recessed neck 82, described neck can enter into the bottom of draw-in groove from the opening part of draw-in groove, fastening block is provided with multiple screw 81, second screw 9 screws in and props up described rear board from screw.
The beneficial effect of this Instrument shell is, 1, described support body is the structure that middle base plate, front panel and rear board are integrally formed, when stirring support body, middle base plate and the connecting line between front panel and rear board can not produce and reverse, pull, the phenomenon mode that the pad portion of connecting line disconnects because pullling can be prevented, this is very convenient to the machine debugging of instrument, simultaneously, base plate is positioned at the middle part of front panel and rear board, in when debugging, on base plate, components and parts can not contact with workbench, avoid components and parts to be collided with; 2, the fixture structure of described support body is simple, can reliably be fixed support body, and that also can remove support body easily is fixing, and this is concerning very convenient the field service work of instrument.3, the parts of this housing are less, and assembly process is simple, and production cost is lower.
