Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figures 1 and 2, controller of the present utility model, comprise button 1, panel 2, adhesive layer 3, center assembly 4, liquid crystal display 5, PCB assembly 6, bonnet, described button 1 is arranged on panel 2, described panel 2 is connected with center assembly 4 by adhesive layer 3, described liquid crystal display 5 is arranged on center assembly 4, described PCB assembly 6 is fixedly connected on center assembly 4, on described PCB assembly 6, be provided with input/output interface, described center assembly 4 is arranged on bonnet, on center assembly 4, be provided with programming data line socket 12, described programming data line socket 12 is connected with input/output interface.Owing to being provided with programming data line socket 12 on center assembly 4, described programming data line socket 12 is connected with input/output interface, and not needing like this controller to take apart just can be directly to 6 programming of PCB assembly.
Described button 1 comprises direction key 1 and common key-press 1, and direction key 1 is matched in clearance with panel 2, and the span of its fit clearance is 0.49mm to 0.51mm; Common key-press 1 is matched in clearance with panel 2, and the span of its fit clearance is 0.2mm to 0.25mm.Select fit clearance in above-mentioned scope both can, so that button 1 is being pressed in process because resistance is little and smooth, can avoid again gap excessive.
PCB assembly 6 is fixedly connected with center assembly 4 by tapping screw, and center assembly 4 is by being installed and be connected with grab by clamp with bonnet.Tapping screw can be connected to PCB assembly 6 on center assembly 4 securely, clamp and grab can realize in framework be connected with can dismantling of bonnet, under not by the condition of external tool, just can realize the installation and removal of center assembly 4 and bonnet.
As shown in Figures 3 and 4, liquid crystal display 5 is connected with center assembly 4 by buckle 11, and described buckle 11 upper ends arrange fastening structure, and the span of the length M of described fastening structure is 0.8mm to 1mm.The value of M in this length range not only can guarantee the intensity of buckle 11 but also can guarantee that buckle 11 is reliably connected with liquid crystal display 5.
As shown in Figure 5, also comprise touch-switch 9, described touch-switch 9 is arranged on, on PCB assembly 6, on described center assembly 4, be provided with cantilever boosting mechanism, one end of described cantilever boosting mechanism is connected on center assembly 4, the other end is unsettled, cantilever boosting mechanism 8 be positioned at button 1 under, described touch-switch 9 be positioned at cantilever boosting mechanism 8 under, and leave gap between cantilever boosting mechanism 8 and touch-switch 9.Because one end of cantilever boosting mechanism is connected on center assembly 4, the other end is unsettled, so it has certain elasticity, and when pushing button 1 time, button 1 compressing cantilever boosting mechanism 8 moves down and touch touch-switch 9; When button 1 unclamps, cantilever boosting mechanism 8 is because its elasticity returns to origin-location, and effectively separated with touch-switch 9.
