Fan electrical connection structure

Abstract

A fan electrical connection structure includes a fan frame, at least one flexible circuit board, and at least one outer circuit board. The fan frame contains an inner circuit board and has an inner channel. The flexible circuit board is disposed within the inner channel of the fan frame and is electrically connected at one end to the inner circuit board. The outer circuit board is disposed on the outer side of the fan frame and is electrically connected to the other end of the flexible circuit board. This invention can save the assembly time and cost of traditional wiring and individual soldering, and can also prevent the flexible circuit board from falling off due to external force.

Claims

1. A fan electrical connection structure, comprising: A fan frame has an internal circuit board disposed therein. The fan frame has an internal channel that connects the outside of the fan frame to the inside. At least one flexible circuit board is disposed in the internal channel of the fan frame. The flexible circuit board has a first connecting portion electrically connected to the internal circuit board and a second connecting portion passing through the outside to electrically connect to an external circuit board, so that the internal circuit board is electrically connected to the external circuit board through the flexible circuit board, and the external circuit board is disposed on the fan frame.

2. The fan electrical connection structure as claimed in claim 1, wherein the frame has an outer surface with a groove formed therein, and the flexible plate is accommodated in the groove.

3. The fan electrical connection structure as described in claim 2, wherein the outer surface is provided with at least one fixing hole, and the outer circuit board is fixed to the fan frame by at least one fixing element through the fixing hole.

4. The fan electrical connection structure as described in claim 1, wherein a connector is provided on the second connection portion, and the flexible board is electrically connected to the outer circuit board via the connector.

5. The fan electrical connection structure as described in claim 1, wherein the outer circuit board has a first mating portion and a second mating portion, the first mating portion being electrically connected to the second mating portion, and the second mating portion being exposed outside the fan frame.

6. The fan electrical connection structure as described in claim 5, wherein the second mating portion has a plurality of metal terminals.

7. The fan electrical connection structure as described in claim 6, wherein the metal terminal is a metal conductor formed by stamping.
