Description

Technical Field

[0001] The utility model relates to the technical field of fans, in particular to a fan. Background Art

[0002] In a device that needs heat dissipation, a cooling fan is usually configured. When the cooling fan needs to be powered by the power supply system of the device, the power cord of the fan needs to be led from the circuit board of the fan to the outside of the fan housing. Since the lead-out line of the power cord is relatively long, it is necessary to fix the power cord at the lead-out port of the housing to prevent the power cord from bulging out.

[0003] The current fan structure is to insert a buckle at the lead-out port of the power cord to fix the power cord. However, in the current power cord fixing method, the buckle is a plastic part. In order to absorb tolerances, there is usually a little gap between the buckle and both sides of the lead-out port; the buckle may move left and right, and even the buckle may become unhooked. If the buckle is designed to be larger, the operation is difficult. When the buckle is snapped in, the buckle is bent and deformed greatly, which still affects the product quality. Summary of the Utility Model

[0004] The utility model mainly solves the technical problem that the buckle of the existing power cord fixing method may move left and right, and even the buckle may become unhooked, and proposes a fan to prevent the buckle from moving left and right, so that the buckle will not become unhooked, the power cord can be fixed more reliably, the power cord can be prevented from bulging out, and the product quality can be improved.
