Background technique

Early cable-type fans obtained power through the combination of power cords and sockets. However, when the cable-type fans needed to be replaced with new ones, the system had to stop running temporarily to take out the old cable-type fans. In order to avoid the need to stop the operation of the entire system when the cable fan is replaced, a hot-swappable fan has been developed in the prior art. When the hot-swappable fan in use needs to be replaced with a new hot-swappable fan, the operator can directly Remove the old hot-swap fan and replace it with a new hot-swap fan, the new hot-swap fan runs as soon as it is connected and does not require system interruption during hot-swap fan replacement running.

However, the hardware of the cable fan and the hot-swappable fan are not compatible, which causes a lot of inconvenience in hardware replacement, replacement, procurement, and management, and it is more likely that the replacement of new hardware will cause inventory resources. Therefore, there is an urgent need in this field to provide an improved electrical transfer method to meet the common requirements between the cable fan and the hot-swappable fan.

Detailed ways

Below in conjunction with accompanying drawing, structural principle and working principle of the present invention are specifically described:

First refer to Figures 1 to 4, wherein Figure 1 is a perspective view of a combination of a fan casing and a fan according to an embodiment of the present invention, Figure 2 is an exploded view of the structure of the embodiment of Figure 1, and Figure 3 is an exploded view of the embodiment of Figure 1 and The assembly diagram of the combination of external circuit boards, Figure 4 is an exploded view of the structure of the embodiment of Figure 3 . In the embodiment shown in FIG. 1 , the fan housing 1 is used to electrically convert a cable fan 10 with a power cord 120 into a hot-swappable fan. The structure of the fan casing 1 includes a fixed casing 20 , a transition casing 30 and a circuit device 40 .

The above-mentioned fixed housing 20 includes a fan accommodating slot 210 for accommodating the cable fan 10. The fan accommodating slot 210 includes a notch 212 and a slot bottom 214.
