Problems solved by technology
[0006] Both of the above two methods need to disassemble the front cover or top cover and unplug the relevant wiring harnesses, and then remove the circuit boards for maintenance, especially when many wiring harnesses need to be plugged and unplugged, the convenience of disassembly and assembly is greatly reduced; in addition, There is a gap between the circuit board and the card slot in the first installation method, which is not completely clamped, and the vibration and shock resistance is poor

The invention discloses a reinforcing device capable of directly locking a circuit board outside a box. The reinforcing device comprises an upper circuit board reinforcing mechanism and a lower circuit board reinforcing mechanism which are the same, each circuit board reinforcing mechanism comprises a wedge-shaped locking assembly, a universal transmission assembly and a locking driving assembly.The upper wedge-shaped locking assembly and the lower wedge-shaped locking assembly are arranged on the upper edge and the lower edge of one side face of a circuit board in the box body, the upper locking driving assembly and the lower locking driving assembly are arranged on the upper portion and the lower portion of the small panel, the small panel is installed in the counter bore table of the front cover plate of the box body, and the small panel and the circuit board are connected through screws to form a hard-connected whole module. The wedge-shaped locking assemblies and the locking driving assemblies are movably connected through the universal transmission assemblies. According to the invention, plugging of the circuit board can be integrally completed without dismounting a front cover plate, the circuit board is directly locked or unlocked outside the box body through the circuit board reinforcing mechanisms, reliable reinforcement of the circuit board is realized, the impact vibration resistance of the whole machine is further improved, and the device has the characteristics of the compact structure, the simple assembly and the convenient operation.
Description
technical field [0001] The invention relates to electronic equipment, in particular to a reinforcement device that can directly lock a circuit board outside a box. Background technique [0002] When electronic equipment is used in vehicle-mounted, airborne and other applications that require high vibration and shock resistance, there are also corresponding requirements for the convenience of equipment maintenance. [0003] The reinforcement method and installation process of the circuit board of the existing electronic equipment chassis are generally the following two methods: [0004] 1. Insert the edge of the circuit board into the card slot of the box body, and then fix the metal plate connected to one end of the circuit board in the box with cross-recessed screws, then plug in the relevant wiring harness, and then install the integral front cover. [0005] 2. Fix the circuit board by pressing the wedge-shaped locking strip installed on the circuit board and the guide ra...
