The third fixing portion 43 is fixed to the assembled plate member 325. The projection of the third fixing portion 43 on the second fixing portion 42 does not overlap with the two screw holes 421 of the second fixing portion 42. Therefore, the screw hole 421 of the second fixing portion 42 can be prevented from being shielded by the third fixing portion 43 from affecting the operation of the locking.

Next, the manner of assembling the filter device 30 will be further described. Please refer to FIG. 4 and FIG. 5. FIG. 4 is a perspective view showing a first step in the assembly process of the filter device of FIG. 1, and FIG. 5 is a perspective view showing a second step of the assembly process of the filter device of FIG. First, the first bracket 3111 of the filter frame 31 of the filter 312 is placed in the accommodating groove 327 and leans against the second plate 322, so that the first bracket 3111 is limited by the first plate 321 and the engaging plate 326. It is located between the first plate member 321 and the engaging plate member 326. Then, the second bracket 3112 and the third bracket 3113 of the filter frame 31 are placed in the accommodating groove 327, and the third plate member 323 interferes with the second bracket 3112 and the third bracket 3113 to temporarily hold the filter frame 31. It is fitted into the receiving groove 327. In this way, the assembly of the filter device 30 is completed.

Next, an operation flow of the filter device 30 installed in the network switch 20 will be described. Please refer to Figure 1 to Figure 3. According to the foregoing, since the filter frame 31 has been temporarily engaged in the accommodating groove 327 of the assembly frame 32, the filter frame 31 is not removed from the assembly frame 32 during the assembly of the filter device 30 and the network switch 20. It affects the operation. First, each of the engaging plate members 326 is respectively aligned with each of the card slots 2121 of the network switch 20 so that the engaging plate members 326 can be pushed into the card slot 2121 along the extending direction of the releasing portion 3261. After the engaging plate member 326 completely enters the card slot 2121, the filtering device 30 is moved along the extending direction of the engaging portion 3262 so that the engaging portion 3262 can be engaged by the top plate 212 of the network switch 20, and the filtering device is The air inlet 3212 of the 30 can be aligned with the air inlet 2112 of the network switch 20. Next, the right and left assembled panels 325 of the filter device 30 are respectively locked to the left and right third fixing portions 43 of the fixed plate member 40 by hand screwing. In this way, the filter device 30 can be assembled with the network switch 20. When the filter device 30 is installed in the network switch 20, before the external airflow is guided into the network switch 20, the airflow first enters the third vent 31131 from the air inlet 3212 of the filter device 30, and then the third The vent 31131 passes through the filter 312 and then enters the network switch 20 by the air inlet 2112. In this way, the airflow can be filtered by the filtering device 30 before entering the network switch 20, and the proportion of dust entrained in the airflow can be reduced.

In addition, in the present embodiment, the fixed plate member 40 and the network switch 20, the filter device 30, and the cabinet 10 are assembled by screws to the screw holes, but are not limited thereto. In other embodiments, the above three can also be fixed by, for example, a buckle.

According to the servo device and the filtering device of the above embodiment, a filtering device is installed at the air inlet of the network switch to filter the airflow entering the network switch, thereby preventing dust in the air from entering the network switch. It affects the transmission speed of the network switch.

In addition, the engaging plate of the filtering device is installed in the slot of the network switch in a sliding manner, which can improve the assembly efficiency between the filtering device and the network switch and prevent the elongated filter frame from being bent and deformed. Or tilt away from the air inlet of the network switch. In this way, the filtering device will reliably provide dust protection to the network switch.

Moreover, a gap is formed because one side of the space is not blocked by the frame. Therefore, the filter device can be directly attached from the top to the bottom of the network switch by letting the gap of the space space, or the filtering device can be directly pulled up from the network switch. That is to say, before the installation and disassembly operation of the filter device and the network switch, it is not necessary to first remove the wire inserted in the connection port, thereby improving the loading and unloading efficiency of the filter device.

While the present invention has been described above in terms of the preferred embodiments thereof, it is not intended to limit the invention, and the invention may be modified and modified without departing from the spirit and scope of the invention. The patent protection scope of the invention is subject to the definition of the scope of the patent application attached to the specification.
