[0017] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0018] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. In contrast, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only."

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0020] like Figures 1 to 3 As shown, a cooling fan lead structure includes a wire 10 and a terminal 20, wherein a plastic shell 30 is provided on the periphery of the terminal 20, wherein the plastic shell 30 covers the terminal 20, and the terminal 20 covers the wire 10, wherein the wire 10 is composed of four parallel wires 110, and the interval between each wire 110 is 2.0±0.01mm; wherein the wire 110 includes a conductor 111 and an insulating layer 112 from the inside to the outside, wherein the insulating layer 112 covers the conductor 111. In the utility model, the wires 110 are distributed in parallel, which can ensure the stability of the circuit voltage and the normal operation of the cooling fan.

[0021] Furthermore, the outer periphery of the wire 10 is coated with a braided mesh 40, and the braided mesh 40 is a PET braided mesh with a thickness of 3.0±0.01 mm. Since the braided mesh 40 is woven from PET material, it has good expandability, smoothness, flame retardancy, and air permeability and heat dissipation performance. In the present utility model, the safety and stability of the wire 10 can be effectively improved, and its service life can be extended.

[0022] Furthermore, heat shrink tube sleeves 50 are respectively provided at both ends of the wire 10, and the heat shrink tube sleeves 50 cover the braided mesh 40, wherein the thickness of the heat shrink tube sleeves 50 is 4.5 mm. In the present utility model, the setting of the heat shrink tube sleeves 50 can play a role of insulation protection, preventing the wire 10 from being corroded by water, dust and other substances or accidents such as electric shock. In actual use, the heat shrink tube sleeves 50 can be selected from different materials and thicknesses according to different needs, so as to play a buffering role in strong earthquakes and protect the safety of electronic components.

[0023] Furthermore, in order to increase the stability of the structure, further improve the safety performance, and prevent leakage, the insulating layer 112 is made of PVC, PE or XLPE.

[0024] Furthermore, the connection terminal 20 is a phosphor copper tin-plated terminal. In the present invention, the phosphor copper tin-plated method can play an anti-corrosion role and ensure the stability of the connection terminal 20.
