Description
Technical Field
The present disclosure relates to fans, and particularly to an axial fan frame electrical connection structure.
Background
Fans are a commonly used heat dissipation device for electronic devices (such as servers and computers) to dissipate heat forcibly. The signal control of the power supply and the circuit board in the general fan is that a fan wire set with an electric connector extends to the outside of the fan frame to be electrically connected with a main board of the preset external host equipment, and the signal and the electric power between the fan circuit board and the main board are transmitted through the fan wire set. However, the fan conductor sets extending outside the fan frame need to be manually wired to prevent the fan conductor sets from interfering with the outflow path of the fluid.
In addition, the electrical connection between the fan circuit board and the fan wire set in the fan is performed by manual bare-handed operation, i.e. after the wire ends of the fan wire set are inserted into the welding holes on the fan circuit board by manual bare-handed operation, the wire ends are welded in each welding hole by a soldering material, so that each wire head is welded and combined on the corresponding welding hole to form a welding point. However, the whole process of the fan circuit board and the fan lead set must be manually welded, if mass production is performed, the assembly and the cost increase of the assembly are required, and besides the problems that the outer coating of the fan lead set is soft or burnt out due to the fact that the lead heads of the fan lead set are heated and overheated by soldering tin during welding are easy to occur, so that the lead heads of the fan lead set are not easy to fix and accurately welded in the welding holes, and the situation that poor contact or false welding of welding points frequently occurs is caused, the situation that the contact or disconnection between the fan circuit board and the fan lead set is caused, the power supply or the signal transmission is unstable, the serious case causes the power failure or the signal transmission is broken, and the fan suddenly fails and can not operate, so that the problems of heat or overheat damage of electronic components (such as a central processing unit or a graphic processor) in electronic equipment are solved.
Therefore, the present inventors and related manufacturers who work in the industry are in the need of researching and improving the problem that the fan wires need to be arranged and the problem that the fan circuit board and the fan wire set can only be assembled by manual welding, which is time-consuming and labor-consuming and causes the increase of manufacturing cost and working hours.

The stator blades 16 are radially arranged between the outer side of the shaft seat 13 and the inner side of the frame 1.
A communication channel 161a is disposed between the shaft seat 13 and the frame 1 to connect the shaft seat 13 and the frame 1. Specifically, the communication gallery 161a is disposed between the outer side of the shaft seat 13 and the inner side of the frame 1, and the communication gallery 161a has two ends respectively facing the shaft seat 13 and the frame 1, one end facing the shaft seat 13 is communicated with the accommodating recess 131, and the other end facing the frame 1 is communicated with the channel 14 through the notch 1421. Optionally, the communication gallery 161a is formed in one of the vanes 16a of the present embodiment. In addition, the side of the communication gallery 161a facing the air outlet 12 may form an open side and be closed by the subsequent cover 4.
The circuit board 2 (e.g. a Printed Circuit Board (PCB)) mounted in the accommodating recess 131 has a supporting arm portion 22 protruding outwards from its peripheral side, one end of the supporting arm portion 22 is connected to the circuit board 2, and the other end forms a free end with a metal contact 23 to form a metal contact end 221 (the supporting arm portion 22 is a printed circuit board non-flexible circuit board (FPC) or a conventional cable).
