FIG. 2A is a schematic perspective view of a fan-end connector and a connector combination portion of the present invention not yet engaged with each other;
FIG. 2B is a perspective view of the fan end connector and the connector combination portion of the present invention; FIG. 2C is an exploded view of the fan according to the present invention. As shown, a fan quick-coupling structure 10 includes a fan 11 and a fan-end connector 12, the fan 11 includes a fan frame body 111 and a wire set 115, although the fan 11 is illustrated as a centrifugal fan in the present embodiment, but is not limited to being an axial fan. The fan frame body 111 has an upper cover 1111 covering a base 1112 and a connector coupling portion 114 protruding outside the fan frame body 111. A sidewall 1113 is disposed between the top cover 1111 and the base 1112 and located at an outer edge of the fan frame body 1111. The sidewall 1113 is integrally formed on the base 1112 and protrudes toward the top cover 1111 or integrally formed on the top cover 1111 and protrudes toward the base 1112, and the sidewall 1113 may also be a separate component combined with the top cover 1111 and the base 1112.
The top cover 1111 and the base 1112 are respectively provided with an air inlet 11111 and an air outlet 11121, and the side wall 1113 is provided with an air outlet 11131. The fan frame body 111 contains a fan wheel 112, a fan circuit board 113, a rotor 117 and a stator 118. The fan wheel 112 corresponds to the air inlets 11111, 11121, and the fan circuit board 113 is under the fan wheel 112. The rotor 117 (including the ring magnet and the iron case) is disposed on an inner side of the impeller 112, and the stator 118 (including an insulating frame set, a silicon steel sheet set between the insulating frame set, and a winding set wound around the silicon steel sheet set and the insulating frame set) is located above the fan circuit board 113 and is spaced from the rotor 117. By electrically connecting the stator 118 to the fan circuit board 113, when the stator 118 is energized, electromagnetic induction is generated with the rotor 117 to drive the rotor 117 to rotate the fan wheel 112.
The connector combining portion 114 protrudes from the sidewall 1113 or the base 1112 to the fan frame body 111, and is integrally formed with the fan frame body 111. That is, the connector combining portion 114 is integrally formed on the sidewall 1113 or the base 1112. In the present embodiment, the connector coupling portion 114 is integrally formed on the sidewall 1113. The connector combining portion 114 has an upper force-bearing surface 1141 to bear an upper external pressure, the connector combining portion 114 is, for example but not limited to, a sliding groove or a notch or a snap or a buckle or a plug, the upper force-bearing surface 1141 is on the same side as the upper cover 1111 or the base 1112 of the fan frame body 111, and in this embodiment, the upper force-bearing surface 1141 is on the same side as the base 1112 (as shown on the upper side).
The wire set 115 has an inner end 1151 connected to the fan circuit board 113 inside the fan frame body 111, and an outer end 1152 exposed from the fan frame body 111 and connected to the fan-end connector 12. The fan end connector 12 has a mating portion 121 correspondingly combined with the connector combining portion 114, and further combined and fixed with the fan frame body 111 to form a combination body. Although the fan-end connector 12 is shown as being coupled to the connector coupling portion 1141 from a side of the connector coupling portion 114, the invention is not limited thereto, and the fan-end connector 12 is coupled to the connector coupling portion 1141 along an orientation of the connector coupling portion 1141, such as a vertical direction or an oblique direction.
And with the connector combination portion 114 selectively disposed on the sidewall 1113 or the base 1112, the fan-end connector 12 is fixed to the sidewall 1113 or the base 1112. In the present embodiment, the fan-end connector 12 is shown protruding from a parallel direction Y1 of the side wall 1113 (i.e. towards the lower side of the fan 11), but the fan-end connector 12 can also protrude from a vertical direction X1 of the side wall 1113 or from a vertical direction Y2 of the base 1112. Thus, the fan 11 can be axially (vertically) or radially (horizontally) assembled with the system main board 22 (see fig. 3).
Furthermore, an outer surface of the fan frame body 111 is optionally provided with a wire accommodating groove 116 for accommodating the wire set 115. The wire set 115 can be accommodated in the wire accommodating groove 116 before or after the fan-end connector 12 is fixed to the fan frame body 111.
Generally, the combination means between the fan 11 and the system motherboard 22 can be implemented by disposing a fixing seat on the system motherboard 22 corresponding to the fan 11, and then connecting and combining the fan 11 and the system motherboard 22 by means of screw locking, clamping or buckling.
Please refer to fig. 3, which is a schematic diagram of the fan disposed on the system motherboard according to the present invention. As shown, when the fan 11 is assembled on a system motherboard (e.g., a computer motherboard) 22 by an automated process, the fan-end connector 12 corresponds to a board-end connector 221 on the system motherboard 22, and the upper force-bearing surface 1141 of the connector combination portion 114 serves as a force-applying and pressing position for bearing an external pressure (e.g., from an automated device such as a press-in jig, a suction cup or a robot arm) to apply a downward pressure, so that the fan-end connector 12 is pressed downward and directly electrically connected (e.g., plugged or contacted) with the board-end connector 221, thereby achieving the automated assembly of the fan 11 and the system motherboard 22. In the present embodiment, the fan-side connector 12 is shown as a connector plug, and the board-side connector 221 is shown as a connector socket or a metal PIN (PIN), but the present invention is not limited thereto, and the other way around.
According to the present invention, by means of the fan quick-coupling structure 10, as the fan 11 is mounted on a system motherboard 22, the fan-end connector 12 is directly electrically connected to the board-end connector 221, so as to be suitable for automatic production without generating redundant fan wires between the fan 11 and the system motherboard 22.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
