Referring to fig. 1 and 3, in the embodiment of the present disclosure, a plurality of conductive wires 21 are arranged side by side on the fan module, and the elastic expansion terminal 3 further has a terminal 31, and the terminal 31 is used for connecting free ends of the conductive wires 21.

Referring to fig. 2 and 3, in the embodiment of the present disclosure, the terminal 31 is provided in the structure of the overlapping groove 32, the conductive wire 21 can be placed in the overlapping groove 32, and after the conductive wire 21 is placed in the overlapping groove 32, the groove wall of the overlapping groove 32 can abut against the outer contour of the conductive wire 21. Preferably, the diameter of the overlapping groove 32 is slightly larger than that of the conductive wire 21, so that the connection between the conductive wire 21 and the terminal 31 is tighter, more stable contact is realized, and the signal and current transmission effect is better.

In the embodiment of the present disclosure, the caliber of the notch 321 of the overlapping groove 32 is smaller than the diameter of the conductive wire 21, so that physical wire clamping can be realized, and the conductive wire 21 is not easy to separate from the overlapping groove 32.

In designing the layout, it should be considered that the conductive through hole 11 on the main board 1 is just aligned to the elastic expansion terminal 3 after the fan module is installed, and preferably, the conductive through hole 11 coincides with the central axis of the elastic expansion terminal 3, so that when the fan module is assembled, the elastic clamping portion 32 of the elastic expansion terminal 3 can be directly inserted into the conductive through hole 11 on the main board 1, and automatic fast assembly is realized.
