Description

Fan connector structure

This creation relates to a fan field, especially a fan connector structure that can achieve rapid assembly and can achieve automatic assembly to save labor and time, cost and uniform quality.

The fan is a commonly used system heat dissipation device, which is often used in electronic equipment to provide forced heat dissipation. The power and signal feedback control of the general fan needs to be electrically connected to the motherboard (system board) of the electronic equipment. The link transmits signals and electricity. Please refer to Figure 1, the traditional general fan connector is mainly electrically connected to a connector 42 and a fan circuit board (not shown) through a plurality of wires 43, and the connector 42 is exposed to a fan frame The outer part of the body 41 is plugged into the pre-set multiple metal terminals 511 of the motherboard 51 of the electronic device through the connector 42 hanging from the end of the wire 43 outside the fan frame 41 during installation. Therefore, after the fan 4 is installed on the motherboard 51 of the electronic device, the connector 42 must be manually connected to the plurality of metal terminals 511 of the motherboard 51 of the electronic device by hand. Makes the assembly complete. However, because the conventional fan 4 connector system and the fan frame 41 are of separate design, the two are connected by exposed and unfixed wires 43, which makes it impossible to perform automated assembly with automated process equipment. Manually, after the connector 42 of the fan 4 is plugged into the plurality of metal terminals 511 of the main board 51 with bare hands, the exposed fan wires 43 must be manually aligned and integrated again with bare hands. In other words That is to say, the entire process when the conventional fan 4 connector and the wire 43 are installed and assembled must be manually assembled and performed by hand. Therefore, if mass production is carried out, it will consume labor and manufacturing man-hours for assembly, and cause costs. improve. In addition, because the exposed fan wire 43 even after passing through the straight line and the whole line, there will still be an extra section (that is, an excessively long electrical wire) that hangs between the fan 4 and the motherboard 51 and interferes with the flow of airflow in the system space. And the adhesion or fall of dust. Therefore, how to improve the conventional fan 4 and the motherboard 51 connector is assembled manually, which cannot be automated, and is time-consuming and labor-intensive, resulting in increased manufacturing costs and uneven assembly quality. It is indeed the first for those who are familiar with this technique. The most important goal.
