Moreover, under the action of the spring piece, the upper locking fastener and the locking portion of the docking module cooperate stably.

Description

Technical Field

[0001] The utility model relates to the field of electronic and electrical products, in particular to a radiator. Background Art

[0002] The patent document with application publication number CN117605698A discloses a quick-connect cooling fan for fixing to a docking module, comprising: a fan frame assembly, forming a hollow cavity, an air inlet and an air outlet connecting the hollow cavity and the outside; a stator assembly, fixedly assembled in the cavity; a fan wheel assembly, rotatably assembled in the cavity, and electromagnetically coupled with the stator assembly; an elastic connection assembly, comprising a plurality of signal terminals directly or indirectly fixed to the fan frame assembly; the signal terminal is electrically connected to the stator assembly through a conductive circuit / wire / flexible flat cable, and one end of the signal terminal is formed with an elastic contact portion exposed outside the fan frame assembly for elastically overlapping with the docking module; a sliding locking portion, fixed or integrated on the fan frame, a sliding groove formed on the sliding locking portion, the sliding groove is used to cooperate with the locking portion on the docking module to be inserted and slide from one end of the sliding groove to the other end to achieve locking, thereby enabling rapid assembly with the docking module.

[0003] Referring to the patent document specification

[0042] of the application publication number CN117605698A, the sliding groove includes an implantation groove and a locking groove that are interconnected, and the maximum width of the implantation groove is greater than the maximum width of the locking groove. During assembly, the quick-connect cooling fan is first assembled downwardly on the surface of the docking module along the up-down direction, and the locking portion of the docking module is correspondingly inserted into the implantation groove; then the quick-connect cooling fan is pushed in a lateral direction perpendicular to the up-down direction, so that the locking portion of the docking module slides relatively from the implantation groove to the locking groove, and the locking portion of the docking module is fixed by hard interference (interference fit) with the inner wall surface of the locking groove, and the hanging ears of the locking portion of the docking module (which can be understood as two extended ears above the T-shaped locking portion) are correspondingly hung on the plastic on both sides of the locking groove, thereby realizing the rapid assembly of the quick-connect cooling fan and the docking module.

[0004] Since the locking part of the docking module is fixed by hard interference with the inner wall surface of the locking groove, the interference fit between the locking ear of the docking module and the plastic on both sides of the locking groove may exceed the force limit of the locking ear of the docking module due to dimensional error, or may exceed the force limit of the plastic on both sides of the locking groove, resulting in the breaking of the locking ear of the docking module or the cracking of the plastic on both sides of the locking groove. Utility Model Content

[0005] The technical problem solved by the utility model is as follows: the quick-connect cooling fan in the prior art is provided with a sliding groove to cooperate with the locking part of the docking module, wherein the sliding groove includes an implanting groove and a locking groove which are interconnected; when cooperated, the interference fit between the hanging ear of the locking part of the docking module and the plastic on both sides of the locking groove may exceed the force limit of the hanging ear of the locking part of the docking module, or may exceed the force limit of the plastic on both sides of the locking groove, resulting in the breaking of the hanging ear of the locking part of the docking module, or the cracking of the plastic on both sides of the locking groove.

Secondly, a tool (such as a screwdriver) is used to press the upper locking fastener downward, the spring sheet is compressed, and the locking portion of the docking module is correspondingly inserted into the lower sliding groove and the upper sliding groove. Then, the cooling fan is pushed forward in a lateral direction (front-to-back direction) perpendicular to the up-down direction, so that the locking portion of the docking module moves relative to the upper sliding groove and the lower sliding groove, and the ears of the locking portion of the docking module (which can be understood as the two extended ears above the T-shaped locking portion) are correspondingly hung on the plastic on both sides of the upper sliding groove (i.e., the plastic of the upper locking fastener), thereby realizing the rapid assembly of the cooling fan and the docking module. Since the upper locking fastener and the lower locking fastener are connected by the spring sheet, the height of the upper locking fastener can be adaptively adjusted with the height of the ears of the locking portion of the docking module to avoid the ear breakage, or the plastic on both sides of the upper sliding groove cracking. Moreover, under the action of the spring sheet, the upper locking fastener and the locking portion of the docking module cooperate stably.

[0008] The bottom of the lock buckle groove is provided with a limiting edge, and the bottom edge of the sliding lock buckle assembly is pressed against the limiting edge. That is, the bottom edge of the lower lock buckle member is pressed against the limiting edge.

When the upper locking fastener is pressed down, the U-shaped elastic part undergoes elastic deformation. The U-shaped connecting part is wrapped around the front end / rear end of the upper locking fastener / lower locking fastener.

[0010] The front and rear parts of the upper locking fastener and the lower locking fastener are both provided with snap-fitting grooves, and the U-shaped connecting part is engaged in the snap-fitting groove, that is, the U-shaped connecting part is embedded in the snap-fitting groove. In this way, the U-shaped connecting part will not protrude laterally from the upper locking fastener / lower locking fastener, which facilitates the upper locking fastener and the lower locking fastener to be smoothly engaged in the locking groove, and facilitates the upper locking fastener to slide up and down along the locking groove smoothly.

[0011] The upper sliding groove and the lower sliding groove both include an implanting groove and a locking groove connected front and back, the implanting groove is circular, the locking groove is strip-shaped, and the width of the locking groove is less than the inner diameter of the implanting groove. During assembly, first, the cooling fan is assembled downwardly on the surface of the docking module along the up-down direction. Secondly, use a tool (such as a screwdriver) to press down the upper locking fastener, the spring is compressed, and the locking portion of the docking module is correspondingly inserted into the implanting groove of the lower sliding groove and the upper sliding groove. Then, the cooling fan is pushed forward in a transverse direction (front-back direction) perpendicular to the up-down direction, so that the locking portion of the docking module moves backward relative to the upper sliding groove and the lower sliding groove into the locking groove, and the hanging ears of the locking portion of the docking module (which can be understood as the two extended ears above the T-shaped locking portion) are correspondingly hung on the plastic on both sides of the locking groove of the upper sliding groove (i.e., the plastic of the upper locking fastener), thereby realizing the rapid assembly of the cooling fan and the docking module.

[0012] The fan frame is fixed with an elastic connection component, which includes an insulating base and a plurality of signal terminals fixed on the insulating base. When the cooling fan is pushed forward in a lateral direction (front-to-back direction) perpendicular to the up-down direction, the locking portion of the docking module moves backward into the locking groove relative to the upper sliding groove and the lower sliding groove, and the signal terminal cooperates with the conductive gold finger on the docking module.
