[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0018] like Figures 1 to 2 As shown in this embodiment, a fan contact pin device includes a fan module 1, a device cover plate 2, and a fan base plate 3. A connecting cavity 4 is provided on one side of the fan module 1, and a contact terminal 5 is provided in the connecting cavity 4. A plurality of contact pins 6 are distributed at the lower end of the contact terminal 5. The device cover plate 2 closes the connecting cavity 4. A wire 7 extends from the inside of the fan module 1. The wire 7 is inserted into the contact terminal 5 and then connected to the contact pin 6. A plurality of contact metal pieces 8 are distributed on the fan base plate 3. The contact pin 6 passes through the device cover plate 2 and is inserted into the contact metal pieces 8.

[0019] In terms of specific structure, the fan module 1 is provided with a rubber plug 9 around its periphery, and the device cover plate 2 is provided with a connection hole 10. The rubber plug 9 is inserted into the connection hole 10. The inner wall of the connection cavity 4 is arc-shaped, the device cover plate 2 is L-shaped, and the outer side of the device cover plate 2 is flush with the outer side of the fan module 1. The side of the connection cavity 4 is provided with a wire groove, and the wire 7 passes through the wire groove.
