At present, in order to solve the problem of heat dissipation, at least one fan is installed in the host computer, and the high heat generated by the heat source is taken out of the system by the flow of gas.

A traditional fan mainly includes a fan frame, a motor and an impeller. And the motor is connected to a power supply end through a wire group, so as to drive the motor to drive the impeller to rotate. The wire group extends out to the outside of the fan along the outer wall of the outlet end of the fan frame. In order to protect the wire group from damage by external force and position the wire group, a buckle is provided at the outlet end of the fan frame so that the wire group is located between the buckle and the wire group. Between the fan frames, it achieves the effect of wire positioning and wire protection.

However, in order to make the buckle be arranged on the outlet end of the fan frame, the structure of the fan frame must be modified to match the shape of the buckle, that is, a rib structure and a slot must be designed at the outlet end of the fan frame to make the buckle The sheet is engaged with the slot to be combined on the fan frame. When assembling, because the structure of the buckle is often asymmetrical, it takes some time to confirm the installation direction. Moreover, the combination between the buckle and the slot may cause permanent damage to the slot. When the buckle is removed due to need, if the buckle is to be reinstalled, the damaged slot will not be able to effectively fix the buckle. piece. Moreover, if the buckle is made of metal, no matter whether the buckle falls or is fixed in the slot, it may cause a short circuit on the circuit board.
