[0025] The embodiment of the present application provides a portable multi-layer circuit board, which solves the problem that dust easily adheres to the inside of the plug interface exposed to the outside, resulting in the multi-layer circuit board being unable to be used properly and reducing the service life of the circuit board.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0027] The utility model embodiment discloses a portable multi-layer circuit board.
[0028] According to the attached Figure 1-5 As shown, it includes a multi-layer circuit board body 1, a plug interface 101 is arranged at the front end of the multi-layer circuit board body 1, and one end of the plug interface 101 is connected to a connecting line 102, and is characterized in that a protective box 2 is arranged on the outer peripheral wall of the multi-layer circuit board body 1, and a plurality of groups of functional boxes 201 are arranged at intervals on the outer wall of one side of the protective box 2, and the positions of the functional boxes 201 correspond to the positions of the plug interface 101; before use, the multi-layer circuit board body 1 is installed inside the protective box 2, and at this time, the connecting holes on one side of the protective box 2 correspond to the positions of the plug interface 101 at the multi-layer circuit board body 1.
[0029] The interior of multiple groups of function boxes 201 are all provided with sealing units 202, and the sealing units 202 include a first sealing plate 2021 and a second sealing plate 2022 located on both sides of the function box 201. The first sealing plate 2021 and the second sealing plate 2022 have a shielding effect on the front end of the plug interface 101, and the ends of the first sealing plate 2021 and the second sealing plate 2022 that are away from each other are provided with driving springs 2025, and the driving springs 2025 generate deformation to drive the first sealing plates 2021 and the second sealing plates 2022 on both sides to slide away from each other. When electrically connecting the connecting wire 102 to the plug interface 101, first pick up one end of the connecting wire 102, align the front end connector 1021 with the front end of the function box 201 on one side, and pass the front end of the connector 1021 through the function box 201, so that the connector 1021 is plugged into the inside of the plug interface 101, so as to connect the connecting wire 102 to the multi-layer circuit board body 1.
[0030] The multilayer circuit board body 1 is located inside the protective box 2, and the multiple groups of function boxes 201 are fixedly installed on one side of the outer wall of the protective box 2. One end of the connecting wire 102 is connected to a connector 1021, and a locking component is provided between the connecting wire 102 and the connector 1021. The front ends of the first sealing plate 2021 and the second sealing plate 2022 on both sides form a triangular shape.
