DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following further Figures 1-3 describes the present application in detail with reference to the attached

[0031] An embodiment of the present application discloses a protective shell.

[0032] Referring to Figure 1 andFigure 2 The protective shell includes a shell 1, and the PCB board is located at the inner edge of the shell 1. In the embodiment of the present application, the shell 1 is made of a transparent material, such as acrylic material, so that the operator can observe the specific situation of the PCB board through the shell 1.

[0033] Reference Figure 1 and Figure 2 A mounting base 2 is fixedly connected to the shell 1, and a plurality of mounting grooves 3 are provided on the surface of the mounting base 2 facing away from the shell 1. Sealing holes 4 matching the size of the pin headers are provided at the bottoms of the plurality of mounting grooves 3. The plurality of pin headers are sequentially passed through the sealing holes 4 and are located in the mounting grooves 3. A plurality of reinforcing ribs 11 are fixedly connected to the surface of the shell 1 facing the PCB board. The reinforcing ribs 11 can effectively increase the mechanical strength of the shell 1, reduce the possibility of deformation or damage of the shell 1 due to external impact, and improve the stability and durability of the shell 1.

[0034] Reference Figure 1 and Figure 2 Two relatively arranged connecting plates 7 are fixedly connected to the shell 1, and a connecting block 8 is fixedly connected to one end of each connecting plate 7 away from the shell 1. The two connecting blocks 8 are both buckled with the PCB board. A plurality of separation grooves 9 are provided at one end of the connecting plate 7 away from the shell 1. In the embodiment of the present application, three separation grooves 9 are provided on each connecting plate 7. The separation grooves 9 enable the connecting plate 7 to be more evenly distributed with the force on the entire connecting plate 7 when subjected to external force. The plurality of separation grooves 9 reduce stress concentration and improve the mechanical strength and durability of the connecting plate 7.

[0035] Therefore, by interlocking the connecting block 8 with the PCB board, the installation and disassembly of the PCB board and the shell 1 are facilitated, the possibility of the PCB board shaking in the shell 1 is reduced, the stability of the connection between the PCB board and the shell 1 is improved, and the protection of the PCB board by the protective shell is facilitated.

[0036] Reference Figure 1 and Figure 2 The housing 1 is provided with a plurality of wiring holes 10, and the housing 1 is provided with a plurality of avoidance holes 12. The avoidance holes 12 play an avoidance role for the components on the PCB board, thereby reducing the interference between the housing 1 and the PCB board. The hole wall of the avoidance hole 12 is provided with a plurality of wiring grooves 13, and the groove bottom of the wiring groove 13 is provided with an arc chamfer 14. The arc chamfer 14 removes the sharp angle of the groove bottom edge of the wiring groove 13, reduces stress concentration, and reduces friction and wear between the cable and the groove bottom edge of the wiring groove 13, thereby reducing the possibility of cutting the cable and increasing the service life of the cable. The design of the arc chamfer 14 can reduce the possibility of dust and debris accumulation in the wiring groove 13, thereby facilitating cleaning and maintenance.

[0037] Therefore, both the wire through-holes 10 and the wire grooves 13 facilitate the passage of cables and the like, enabling the connection between the PCB and external devices, improving the neat layout of the PCB cables, reducing cable chaos and crossing, enhancing the overall aesthetics and maintenance convenience. At the same time, the design of the wire through-holes 10 can increase the air circulation inside the housing 1, contributing to the dissipation of heat inside the housing 1 and improving the heat dissipation performance.

[0038] Referring to Figure 2 and Figure 3 , a limiting block 5 is fixedly connected to the outer edge of the mounting base 2; when the pin header is inserted into the female header, the limiting block 5 is buckled with the female header, and an inclined guiding groove 6 is formed on the surface of the limiting block 5 facing away from the mounting base 2. Therefore, when installing, the pin header is inserted into the female header, and the limiting block 5 is buckled with the female header to reduce the loosening or falling off of the female header under the action of external force, improving the stability when the pin header is connected to the female header. The inclined guiding groove 6 enables the female header to gradually adjust its direction along the guiding groove 6 during the insertion process, and the guiding groove 6 plays a guiding role, facilitating the precise docking of the female header and the pin header.

[0039] The implementation principle of the embodiment of the present application is as follows: The PCB is placed on the inner edge of the housing 1, and the pin header passes through the sealing holes 4 on the mounting base 2 in sequence and is located in the mounting groove 3. The mounting groove 3 protects the pin header located in the mounting groove 3, reducing the possibility of damage to the pin header under the action of external force. At the same time, the housing 1 protects the PCB, reducing the possibility of the PCB being infected by external liquid or impurities leaking into the PCB. The housing 1 plays a waterproof role while improving the performance of the PCB.
