1. Technical Field
The present disclosure relates to a mounting apparatus for mounting a bracket of a heat sink.
2. Description of Related Art
Heat sinks are typically mounted on electronic components (such as chipsets) by a bracket to dissipate heat. The bracket is usually fixedly mounted on a printed circuit board, on which the electronic components are attached. When the printed circuit board needs to be maintained, it is inconvenient to detach the bracket.
Therefore, there is room for improvement within the art.
Many aspects of the embodiments can be better understood with reference to the following drawings. The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the embodiments. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
The disclosure is illustrated by way of example and not by way of limitation in the figures of the accompanying drawings in which like references indicate similar elements. It should be noted that references to “an” or “one” embodiment in this disclosure are not necessarily to the same embodiment, and such references mean “at least one.”
A chipset 51 is mounted on the circuit board 50. The circuit board 50 defines a pair of first sliding grooves 52 adjacent to a first side of the chipset 51. The circuit board 50 further defines a pair of second sliding grooves 53 adjacent to a second side of the chipset 51 opposite to the first side.
A center portion of the bracket 10 defines an opening 11 corresponding to the chipset 51. The chipset 51 contacts a heat sink (not shown) via the opening 11. The bracket 10 includes a pair of first securing feet 121 on one side and a pair of second securing feet 122 on another side opposite to the pair of first securing feet 121. Each of the first securing feet 121 includes a first post 141 extending down. Each of the second securing feet 122 includes a second post 142 extending down. A distal end of each of the first securing foot 121 includes a first resisting end 151. A distal end of each of the second securing foot 122 includes a second resisting end 152.
Referring to
The elastic pieces 30 can be elastically deformed. A center portion of the elastic piece 30 is an abutting portion 32, and on opposite ends of the elastic piece 30 is a pair of securing portions 31. The abutting portion 32 extends out from the securing portions 31.

Referring to
The first posts 141 on the pair of first securing feet 121 are inserted and slide into the first sliding grooves 52 of the circuit board 50 so that the first resisting ends 151 are located below the first restricting pieces 22 and abut against the abutting portions 32 of the pair of elastic pieces 30. This elastically deforms the elastic pieces 30. In this position, the second posts 142 on the pair of second securing feet 122 are inserted and slide into the second sliding grooves 53 so that the second resisting ends 152 are below the second restricting pieces 42. When the bracket 10 is released, the elastic pieces 30 elastically push the bracket 10 so that the second resisting ends 152 abut against the second mounting bases 41. Thereby, the bracket 10 is mounted on the circuit board 50.
The bracket 10 is detached from the circuit board 50 by moving the bracket 10 against the abutting portions 32 of the pair of elastic pieces 30 so that the second resisting ends 152 slide out of the second securing members 40. Thus, the bracket 10 is easily removed from the circuit board 50.
It is to be understood, however, that even though numerous characteristics and advantages of the embodiments have been set forth in the foregoing description, together with details of the structure and functions of the embodiments, the disclosure is illustrative only, and changes may be made in detail, especially in the matters of shape, size, and arrangement of parts within the principles of the present disclosure to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
