Detailed Description
The following description of the embodiments of the present utility model will be made more apparent and fully hereinafter with reference to the accompanying drawings, in which some, but not all embodiments of the utility model are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 to 4, an electronic device according to an embodiment of the utility model includes an insulating heat dissipation plate 10, a housing 20, a locking structure 30 and a plurality of locking members 40. The locking structure 30 can assemble the insulating heat dissipation plate 10 and the housing 20 together by the locking members 40. The locking member 40 is, for example, but not limited to, a screw.
The insulating heat dissipation plate 10 is provided with a plurality of fixing holes 11. The respective fixing holes 11 correspond to one locking member 40.
The housing 20 is provided with a plurality of openings 21. The respective openings 21 correspond to a locking member 40.
The locking structure 30 comprises a plurality of support cylinders 31. The support cylinder 31 is made of, for example, but not limited to, metal, for example, but not limited to, copper. The respective support cylinders 31 correspond to a fixing hole 11, an opening 21 and a locking member 40. Each support tube 31 includes a first end 32, a second end 33 opposite the first end 32, and a through hole 34 extending from the first end 32 to the second end 33.
The first ends 32 of the respective support cylinders 31 may be fixed in the corresponding fixing holes 11 of the insulating heat dissipation plate 10. The through-holes 34 of each support cylinder 31 allow the corresponding locking members 40 to be inserted therein by the first ends 32 after passing through the corresponding apertures 21 in the housing 20.
The outer diameter of the first end 32 of each support barrel 31 is greater than the outer diameter of the second end 33.
The first end 32 of each support tube 31 has an outer diameter greater than the aperture of the corresponding opening 21 in the housing 20.
The inner wall surface 35 of the through hole 34 of each support cylinder 31 is provided with an internal thread 36 at the first end 32. The internal threads 36 cooperate with the threads 41 of the corresponding locking member 40 to lock the corresponding locking member 40 from the first end 32 into the through hole 34.
The electronic device of the present utility model further comprises a circuit board 50 and a plurality of positioning members 60. The retainer 60 is, for example and without limitation, a nut. Each support barrel 31 further includes a stop 39 between the first end 32 and the second end 33, the stop 39 being, for example and without limitation, in the shape of an annular step. The stop portion 39 can be supported by the circuit board 50.
The circuit board 50 is provided with a plurality of mounting holes 51. The respective mounting holes 51 correspond to one support cylinder 31 and one positioning member 60. Each mounting hole 51 of the circuit board 50 is configured to allow the second end 33 of the corresponding support cylinder 31 to pass through.
The second end 33 of each support tube 31 is configured to receive a corresponding positioning member 60 thereon. Specifically, the outer surface 37 of each support tube 31 has an external thread 38 at the second end 33, and the external thread 38 cooperates with the thread 61 of the corresponding positioning member 60 to lock the corresponding positioning member 60 to the second end 33.
The aperture of each mounting hole 51 of the circuit board 50 is smaller than the outer diameter of the first end 32 of the corresponding support cylinder 31.
In assembly, since the support cylinder 31 is fixed to the fixing hole 11 of the insulating heat dissipating plate 10, the second end 33 of the support cylinder 31 can be directly inserted into the mounting hole 51 of the circuit board 50 until the circuit board 50 is seated against the stopper 39 of the support cylinder 31, and then the positioning member 60 is locked to the second end 33 of the support cylinder 31. Thus, the circuit board 50 can be fixed to the insulating heat dissipation plate 10, the circuit board 50 can be positioned between the stopper 39 and the positioning member 60 of the support cylinder 31, and the circuit board 50 positioned on the support cylinder 31 is spaced apart from the insulating heat dissipation plate 10 fixed to the support cylinder 31. Next, the locking element 40 is inserted into the opening 21 of the housing 20, and then the locking element 40 is locked in the through hole 34 of the supporting cylinder 31 from the first end 32 of the supporting cylinder 31. Thereby, the insulating heat sink 10 can be fixed to the case 20.
On the other hand, the insulating heat dissipation plate 10 may be fixed to the case 20 in another manner. As shown in fig. 5, the locking member 70 (such as, but not limited to, a screw) is inserted into the through hole 34 of the support cylinder 31 from the second end 33 of the support cylinder 31, then passes through the corresponding opening 21 of the housing 20, and finally the stopper 80 (such as, but not limited to, a nut or washer) is sleeved and locked on the locking member 70. The specifications of the locking member 70 are, for example and without limitation, different from the specifications of the locking member 40.
In addition, the present utility model does not limit the number of fixing holes 11 of the insulating heat dissipation plate 10, the number of openings 21 of the case 20, the number of support cylinders 31, the number of locking pieces 40, the number of mounting holes 51 of the circuit board 50, the number of positioning pieces 60, the number of locking pieces 70, and the number of stoppers 80. As long as the insulating heat dissipating plate 10, the case 20, and the circuit board 50 can be assembled together, and the components that need to be fitted to each other can be corresponded to each other, the number of the fixing holes 11, the number of the openings 21, the number of the supporting cylinders 31, the number of the mounting holes 51, and the number of the positioning pieces 60 can be changed to one or more. The number of the locking members 40, the number of the locking members 70 and the number of the limiting members 80 depend on the manner in which the insulating heat dissipation plate 10 is fixed to the housing 20. For example, when more than one locking member 40 is used, no locking member 70 or stop 80 is used; conversely, when more than one locking member 70 and corresponding stop members 80 are used, no locking member 40 is used.
The foregoing description of the preferred embodiments of the utility model is not intended to limit the scope of the utility model, but rather to cover any modifications, equivalents, improvements or the like within the spirit and scope of the present utility model.
