Description

Technical Field

[0001] The utility model relates to the technical field of circuit board protection, in particular to a circuit board protection structure. Background Art

[0002] A circuit board is a carrier used to connect and support electronic components in electronic devices. It is also called a printed circuit board or printed circuit board. A circuit board is an indispensable core part of electronic products. It consists of pads, vias, mounting holes, wires, etc. It is mainly used to connect component pins and circuits. The design and production process of a circuit board includes steps such as circuit schematic design, wiring, welding, vias, mounting holes, and wire layout.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] In the examples of this application, please refer to Figure 1 A circuit board protection structure includes a shell 10. The shell 10 is a shell structure of an existing circuit board installation position. The specific shell of the product depends on the actual situation. The shell 10 is fixedly connected to a fixing plate 20. The fixing plate 20 is also located on the inner side of the shell 10 as a whole. The fixing plate 20 is fixedly connected to a plurality of connecting posts 21 for installing a circuit board 30. The circuit board 30 refers to the installed circuit board body. The circuit board 30 is connected to the connecting posts 21 in an existing manner, such as by screw connection. A protective shell 40 connected to the fixing plate 20 is provided on the outside of the circuit board 30. When in use, after the circuit board 30 is installed, the protective shell 40 is immediately used for protection, so that when other structures in the shell 10 are subsequently processed, the circuit board 30 will not be touched, thereby not damaging the circuit board 30, thereby ensuring its stability in use and making it more convenient to use.

[0035] In a further embodiment, please refer to Figure 1 , 2 3, the protective shell 40 is connected to the fixed plate 20 at one end by a connecting structure 60, and the other end is connected by a limiting structure 70, wherein the connecting structure 60 includes a fixing sleeve 61 fixed to the top of the fixing plate 20, and a plug-in block 62 plugged into the inside of the fixing sleeve 61 is fixed on one side of the protective shell 40. When connecting, first insert the plug-in block 62 as shown in Figure 3 It can be inserted into the fixing sleeve 61 and then fixed by the limiting structure 70 .

[0036] Specifically, the limiting structure 70 includes a fixing seat 71 fixed to the top of the fixing plate 20, a fixing block 72 is fixed to the other side of the protective shell 40, a rotating shaft 74 is fixed inside the fixing seat 71, a rotating block 73 located inside the fixing seat 71 is rotatably sleeved on the outside of the rotating shaft 74, a limiting block 75 located on the top of the fixing block 72 is fixedly connected to the rotating block 73, a handle 77 extending to the outside of the fixing seat 71 is fixedly connected to the rotating block 73, and a torsion spring 76 is sleeved on the outside of the rotating shaft 74, one end of the torsion spring 76 extends to the inside of the rotating shaft 74, and the other end extends to the inside of the rotating shaft 74. To the inside of the limit block 75, under normal circumstances, the torsion spring 76 is in a tightened state, and the restoring force of the torsion spring 76 will be given to the rotating block 73 and the limit block 75, so that the limit block 75 always presses the fixed block 72 to ensure the stability of the protective shell 40. When disassembling or installing, the handle 77 is pressed down to drive the rotating block 73 to rotate, thereby driving the limit block 75 to tilt up, and then the fixed block 72 can be lowered or lifted to complete the installation or disassembly, and then the handle 77 is released, and the limit block 75 can be driven to the initial position by the restoring force of the torsion spring 76. The operation is simple.

[0037] At the same time, a soft pad 50 is fixed on the top of the fixing plate 20 . The soft pad 50 is arranged between the fixing plate 20 and the protective shell 40 . The soft pad 50 is preferably a rubber pad, which can increase the sealing between the fixing plate 20 and the soft pad 50 .

[0038] Furthermore, a spare plate 41 is embedded on the side of the protective shell 40, and the spare plate 41 is connected to the protective shell 40 by a plurality of small plastic blocks. When it is necessary to lead out the circuit at the circuit board 30, the spare plate 41 is pushed open with force. The small plastic blocks are relatively fragile and can be easily broken. After all of them are broken, the spare plate 41 can be removed and then used for threading.

[0039] In order to further increase the strength of the protective shell 40 , a plurality of vertical bars 43 and horizontal bars 42 are fixed to the top of the inner wall of the protective shell 40 , and the vertical bars 43 and the horizontal bars 42 are cross-arranged.
