Description

Fan electric connection structure Technical Field The present utility model relates to fans, and more particularly to an electrical connection structure for fans, which can eliminate the need for arranging wires and soldering the wires one by one to save assembly time and assembly cost. Background The fan is a common system heat dissipation device, and is often applied to electronic equipment (such as a server or a computer) to provide forced heat dissipation, especially a fan with more than two motors is better in forced heat dissipation effect, but the control circuit board signals in the fan need to be extended to a main board of an external host device for electric connection, and the control circuit board and the main board are electrically connected by a golden finger printed circuit board, while the golden finger printed circuit board is fixed on a fan frame of the fan in the prior art, the control circuit board in the fan is electrically connected with the golden finger printed circuit board by a plurality of wires, the wires of the control circuit board need to be led out from the fan frame and welded on the golden finger printed circuit board, and the wires need to be distributed and managed in the fan frame, but the space for managing wires is limited, so that the arrangement and the management of the wires are inconvenient, and the wires need to be welded on the golden finger printed circuit board under the condition of high difficulty in arrangement and management, the situation that the wires are difficult to be assembled one by one, and the problem of assembly cost and the like can be caused. Therefore, how to improve the problems of wire arrangement and wire management in the limited space of the fan and the problem of the increase of assembly time and assembly cost caused by difficult welding is a great need for research and improvement by the designer and the related manufacturers in the industry. Disclosure of utility model Therefore, in order to effectively solve the above-mentioned problems, a main object of the present utility model is to provide a fan electrical connection structure using a flexible printed circuit board for electrical connection, which can effectively utilize the limited space in the fan and save the assembly time and assembly cost consumed by arranging and soldering the wire-arranging wires. Another objective of the present utility model is to provide a fan electrical connection structure that can be completely attached to prevent the flexible printed circuit board from falling off due to external force. Another objective of the present utility model is to provide a fan electrical connection structure that can reduce the wiring and wire arrangement space, and further can increase the fan blade axial distance or reduce the installation volume of the fan frame. In order to achieve the above-mentioned objective, the present utility model provides a fan electrical connection structure, which comprises a fan frame, at least one flexible board and at least one external circuit board, wherein an internal circuit board is disposed in the fan frame, and the fan frame has an internal channel for communicating the interior and the exterior of the fan frame. The flexible board is arranged in the inner channel of the fan frame body, one end of the flexible board is provided with a first connecting part which is electrically connected with the inner circuit board, and the other end of the flexible board is provided with a second connecting part which is electrically connected with the outer circuit board, so that the inner circuit board is electrically connected with the outer circuit board through the flexible board. The frame body is provided with an outer surface provided with a groove, and the soft board is accommodated in the groove. The outer surface is provided with at least one fixing hole, and the outer circuit board is fixed on the fan frame body through the fixing hole by at least one fixing component. The second connecting part is provided with a connecting joint, and the flexible board is electrically connected with the external circuit board through the connecting joint. The outer circuit board is provided with a first butt joint part and a second butt joint part, the first butt joint part is electrically connected with the second connecting part, and the second butt joint part is exposed out of the fan frame body.
