DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 schematically illustrates a computing device 20, an example of which is a server. Computing device 20 generally includes base board 22, input/output 24, memory 26 and processor 28. Base board 22 connects input/output 24, memory 26 and processor 28 and serves as an electronic highway between such units. Input/output 24 generally comprises an input/output board coupled to base board 22. For purposes of this disclosure, the term “coupled” means the joining of two members directly or indirectly to one another. Such joining may be stationary in nature or movable in nature. Such joining may be achieved with the two members or the two members and any additional intermediate members being integrally formed as a single unitary body with one another or with the two members or the two members and any additional intermediate member being attached to one another. Such joining may be permanent in nature or alternatively may be removable or releasable in nature. The input/output board generally supports a plurality of input/output cards. Input/output 24 facilitates the use of additional peripherals such as tape drives, DVDs and the like with computing device 20.
Memory 26 is coupled to base board 22 and provides additional memory storage for computing device 20. In the particular embodiment shown, memory 26 comprises two memory extenders comprising boards carrying a plurality of memory cards.
Processor 28 does much of the computing or calculations for computing device 20 and generally includes a processor board or circuit board 30, a plurality of processor components 32 and a control 34 (known as a computer electronic control or CEC). Circuit board 30 generally comprises a conventionally known or future developed circuit board (also known as a printed circuit assembly) capable of serving as an interface between the various elements connected to circuit board 30. Circuit board 30 is coupled to base board 22 and electronically connects each of processor components 32 to control 34.
Control 34 serves as a traffic cop between each of the processor components 32 and memory 26. Although not shown, computing device 20 may additionally include a power supply for supplying power to each of the components, one or more cooling fans and a housing for enclosing and supporting each of the components. Overall, input/output 24, memory 26 and processor 28 cooperate with one another to provide information retrieval and processing.
As shown in FIGS. 2-6, processor 28 additionally includes at least one frame 36, 38 and attachment mechanisms 40. FIG. 2 is a perspective view of circuit board 30, components 32, frame 36, 38, and attachment mechanisms 40 which are collectively referred to as the circuit board support assembly 42. Frames 36 and 38 support and rigidify circuit board 30. Frames 36 and 38 extend on opposite sides of circuit board 30 in closely abutting contact with circuit board 30. FIG. 3 depicts circuit board support assembly 42 without circuit board 30 and components 32 to better illustrate frames 36 and 38. As best shown by FIG. 3, frames 36 and 38 each include perimeter portions 58 which extend about the perimeter of circuit board 30 and support spanning portions 60 that extend between opposite perimeter portions 58 across circuit board 30 to further rigidify the intermediate portions of circuit board 30. Frames 36 and 38 are generally formed by deformed sheet metal. As a result, frames 36 and 38 are lighter in weight and less expensive as compared to cast frames. Although less desirable, frames 36 and 38 may alternatively be formed from cast metal, machined metal or a molded polymer. Frames 36 and 38 may also have a variety of different configurations.
With reference to FIG. 2, processor components 32 are located on opposite sides of circuit board 30 in an electrical connection with circuit board 30. The processor components 32 illustrated constitute just one example of an electronic component that may be employed as part of circuit board support assembly 42 depending upon the computing device in which it is implemented. For purposes of disclosure, the term “electronic component” means any computing device element which communicates with or through circuit board 30. FIGS. 4 and 5 illustrate processor component 32 in greater detail. As shown by FIGS. 4 and 5, processor component 32 generally includes power supply 60, processor assembly 62 and heat sink 64. Power supply 60 generally delivers power to processor assembly 62. Power supply 60 is secured adjacent to an underside of heat sink 64 by a fastener 69.
Processor assembly 62 receives power from power supply 60 and processes information provided to it through circuit board 30. Heat sink 64 extends above and adjacent to both power supply 60 and processor assembly 62 and is configured to dissipate generated heat from power supply 60 and processor assembly 62. Heat sink 64 generally includes a platform 80 and cooling fins 81. Platform 80 supports cooling fins 81 and provides a structure for mounting the remainder of heat sink 64, power supply 60 and processor assembly 62 to one of frames 36, 38 using attachment mechanisms 40. In the particular embodiment illustrated, platform 80 includes a plurality of recessed flats 82 which bear against attachment mechanisms 40. Platform 80 additionally defines bores adjacent to flats 82 through which attachment mechanisms 40 are coupled to platform 80.
Overall, power supply 60 provides power to a processor assembly 62 which receives information via circuit board 30 and processes such information. At the same time, heat sink 64 dissipates heat generated by both power supply 60 and processor assembly 62. FIGS. 4 and 5 illustrate but one example of such a processor. Depending upon the computing device, component 32 may be provided with alternatively configured power supplies, alternatively configured processor assemblies, and alternatively configured heat sinks. Furthermore, in alternative applications, component 32 may omit power supply 60 and may include alternative component parts besides processor 72. Depending upon the amount of heat generated by such component parts, component 32 may or may not include heat sink 64.
FIGS. 6 and 7 illustrate attachment mechanisms 40 in greater detail. Each attachment mechanism 40 couples both circuit board 30 and electronic component 32 to either frame 36 or frame 38 along a single common axis. As compared to circuit board support assemblies which attach components of the circuit board to frame along distinct axes, circuit board support assembly 42 requires less space across circuit board 30 with fewer attachment points along either frames 36 or 38. Consequently, circuit board 30 may support additional components and frame 36 and 38 may provide a greater degree of rigidity to circuit board 30. In addition, the assembly of circuit board support assembly 42 is simpler, less time consuming, and more cost effective.
FIG. 7 illustrates single attachment mechanism 40 extending above frame 36 joining circuit board 30 and component 32 to frame 36. The following description of the particular attachment mechanism 40 equally applies to those attachment mechanisms 40 extending below frame 38 and coupling circuit board 30 and component 32 to frame 38. The use of such terms as upward and downward, above and below, and the like, are merely chosen to describe the relationship between the elements as depicted in the figures and do not imply or require any particular orientation of circuit board support assembly 42 or its elements. For example, one element may extend upwardly, downwardly or sideways with respect to another element depending upon the orientation chosen for the circuit board support assembly 42.
As best shown by FIG. 7, each attachment mechanism 40 generally includes attachment structure 100, fastener 102, fastener 104, and spring 106. Attachment structure 100 generally comprises a rigid structure configured to extend away from frame 36 to support component 32 proximate to circuit board 30. Attachment structure 100 is further configured to cooperate with fasteners 102 and 104 to attach at least one of circuit board 30 and component 32 relative to frame 36.
In the particular embodiments shown in FIGS. 1-7, attachment structure 100 preferably comprises a standoff having frame end 110 nonrotatably attached to frame 36, a component end 112 bearing against flat 82 of heat sink 64, internal bore 114 receiving fastener 102, and internal bore 116 receiving fastener 104. In the embodiment shown, end 110 is pressed into frame 36 such that structure 100 cannot rotate relative to frame 36. In one embodiment, end 110 is noncircular in shape and is pressed into frame 36 such that frame 36 acts as a collar about structure 100. Bores 114 and 116 threadably engage fasteners 102 and 104, respectively. Because end 110 is nonrotatably coupled to frame 36, circuit board 30 and component 32 are secured to frame 36 without structure 100 rotating or spinning, facilitating easier assembly and disassembly of component 32 and reducing any risk of damage to circuit board support assembly 42 during assembly.
Although structure 100 is illustrated as being pressed into frame 36, structure 100 may alternatively be nonrotatably attached to frame 36 by other methods. For example, end 110 may alternatively have a non-circular shape which is received in a non-circular depression or aperture formed in frame 36, wherein end 110 mates with frame 36 to prevent rotation. Although structure 100 is illustrated as a standoff, structure 100 may alternatively comprise other structures extending between frame 36 and component 32. Because attachment structure 100 comprises a separate member distinct from both component 32 and frame 36, neither frame 36 nor component 32 require an upwardly or downwardly extending extension formed as part of either component 32 or frame 36. As a result, construction of both component 32 and frame 36 is simpler and less expensive.
Fastener 102 cooperates with structure 100 to couple circuit board 30 to frame 36. Fastener 102 extends through an aperture 119 in circuit board 30 into bore 114, capturing circuit board 30 between the head of fastener 102 and frame 36. Although fastener 102 is illustrated as a threaded bolt, fastener 102 may alternatively comprise other conventionally known or future developed fasteners configured to releasably or permanently attach to structure 100 so as to retain circuit board 30 against frame 36. For example, fastener 102 may alternatively comprise a screw configured to extend through circuit board 30 and into structure 100, wherein both or neither of circuit board 30 and structure 100 are provided with aligned apertures or bores for the receipt of the screw. Fastener 102 may also alternatively comprise a unidirectional one-way fastener. A unidirectional fastener is a fastener that is movable into engagement with another member in a single direction to prevent relative movement between the fastener and the member in the opposite direction. An example of one unidirectional fastener is toggler. Although fastener 102 is illustrated as extending into bore 114 and structure 100, structure 100 and fastener 102 may alternatively be configured such that structure 100 includes a portion projecting from end 110 such as a threaded stud, wherein fastener 102 includes a threaded bore which receives the threaded stud to couple fastener 102 and structure 100 together and to capture circuit board 30 therebetween.
Fastener 104 cooperates with structure 100 to couple component 32 to structure 100 and thereby couple component 32 to frame 36. Fastener 104 extends through component 32 into bore 116 of structure 100 while bearing against component 32. In the particular embodiment shown, fastener 104 bears against spring 106 to compress spring 106. Alternatively, fastener 104 may directly bear against component 32. Although fastener 104 is illustrated as an elongate threaded bolt extending through a washer 118 in threaded engagement with bore 116, fastener 104 may alternatively comprise other conventionally known or future developed fasteners to releasably or permanently couple component 82 to structure 100. For example, fastener 104 may alternatively comprise a screw to extend through component 82 and into structure 100. Fastener 104 may also alternatively comprise a unidirectional fastener such as a toggler.
Spring 106 extends between the head of fastener 104 and component 32. Spring 106 resiliently biases component 82 towards frame 36 and circuit board 30. Spring 106 regulates the amount of force by which those portions of component 82 which are electrically connected to circuit board 30 are pressed against circuit board 30. Although less desirable, spring 106 may be omitted and fastener 104 may be reconfigured such that fastener 104 directly bears against component 82 to couple component 82 to structure 100 and frame 36.
FIG. 6 illustrates the use of attachment mechanisms 40 in greater detail. As shown by FIG. 6, attachment mechanisms 40 extend in opposite directions relative to circuit board 30 and join circuit board 30 to both frames 36 and 38, as well as to electronic components 32 located on opposite sides of circuit board 30. In particular, each attachment mechanism 40 couples component 32 and circuit board 30 to an intermediate frame 36 or an intermediate frame 38 along a single axis 120. Coupling circuit board 30 and components 32 to frame 36, 38 along a single axis 120 conserves space adjacent circuit board 30 which would otherwise be required to carry component fastening structures. Coupling all three elements along a single axis 120 further reduces the number of connection points required along frame 38, increasing the structural rigidity provided by frames 36 and 38 to circuit board 30. Moreover, the assembly of board support assembly 40 is simpler and less time consuming.
In addition, attachment structures 100 cooperate with flats 82 of heat sink 64 to provide a hard stop to minimize the transmission of loads to component 32. Because attachment structures 100 bear against flat 82 located at each of the four corners of heat sink 64, undesirable rocking of heat sink 64 and component 32 is minimized as the component 32 is being seated. Moreover, attachment structure 100 enables the construction of heat sink 64 to be simplified by eliminating the need to add material to the face of heat sink 64 to provide a hard stop to minimize loads transmitted to component 32.
Because structure 100 is pressed into frame 36, structure 100 is attached to frame 36 without additional fasteners. As a result, fasteners 102 may be omitted from selected attachment mechanisms 40 in circumstances where circuit board 30 is sufficiently secured to frame 36 by other attachment mechanisms 40 including fasteners 102. Although fasteners 102 are illustrated as having heads substantially recessed in counter sinks 103 to conserve space adjacent to the opposite frame having the counter sink 103, fasteners 102 may alternatively have heads which bear against the opposite frame 36, 38 to further secure the opposite frame 36, 38 to board 30. Although attachment mechanisms 40 are illustrated as part of assembly 40 which includes frames and components on both sides of circuit board 30, assembly 40 may alternatively have a frame and components on only a single side of circuit board 30.
Overall, the circuit board support assembly 42 shown in FIGS. 2-6 incorporates two beneficial features which optimize the functioning of assembly 40. These features include: (1) the coupling of component 32 and circuit board 30 to frame 36 or frame 38 along a single common axis and (2) the use of an attachment structure that is non-rotatably attached to the frame, preventing the attachment structure from undesirably spinning or rotating during attachment of the component 32. Although less desirable, each of these features may be independently employed on a circuit board support assembly. For example, as will be described hereafter with respect to FIGS. 8-11, components 32 and circuit board 30 may alternatively be coupled to one or both of frames 36 and 38 along a single common axis using attachment structures that are rotatably coupled to adjacent frame 36, 38. Likewise, although the attachment structure 100 shown in FIG. 7 is illustrated as coupling component 32 and circuit board 30 to frame 36 along a single common axis, attachment structure 100 may alternatively be employed to couple only component 32 to frame 36, wherein circuit board 30 would be coupled to frame 36 by other attachment mechanisms or methods. Methods of this application are shown in FIG. 6 in which certain attachment mechanisms 40 omit fastener 102. As shown by alternative attachment structure 150 in FIG. 6, end 110 may not need to be configured to attach to fastener 102 such that bore 114 may be omitted.
FIGS. 8-11 illustrate the alternative embodiments of attachment structure 100 configured to couple component 32 and circuit board 30 to frame 36 and frame 38. FIG. 8 illustrates attachment structure 200, an alternative embodiment of attachment structure 100. Attachment structure 200 is substantially similar to attachment structure 100 except that attachment structure 200 has an end portion 110 threaded or screwed into frame 36, rather than being pressed into frame 36. Although end 110 of structure 200 is illustrated as being screwed directly into frame 36, end 110 may alternatively be screwed into a threaded insert which is itself screwed into frame 36 such as when frame 36 is a cast frame as otherwise formed from a softer material necessitating the use of insert of a harder material. Like attachment structure 100, attachment structure 200 is part of an attachment mechanism 240 which couples component 82 and circuit board 30 to frame 36 along a single axis conserving space and reducing assembly complexity.
FIG. 9 illustrates attachment structure 300 as part of an attachment mechanism 340. Attachment structure 300 is substantially similar to attachment structure 100 except that end 110 of attachment structure 300 bears against an upper surface of frame 36. In this alternative application, aperture 303 through which fastener 102 extends is preferably dimensioned in close tolerance with fastener 102 to prevent or substantially minimize any relevant movement of frame 36 and structure 300. Like attachment structure 100, structure 300 couples component 82 and circuit board 30 to frame 36 along a single common axis.
FIG. 10 illustrates attachment structure 400, an alternative embodiment of attachment structure 100, as shown in FIG. 7. Attachment structure 400, as part of attachment mechanism 440, is similar to attachment structure 100 except that end 110 of attachment structure 400 is integrally formed as a single unitary body with frame 36. As such, attachment structure 400 is rotatably coupled to frame 36 and nonrotatably attached to frame. Like attachment structure 100, attachment structure 400 couples component 32 to circuit board 30 to frame 36 along a single axis.
FIG. 11 illustrates attachment structure 500, an alternative embodiment of attachment structure 100. Attachment structure 500, as part of attachment mechanism 540, is similar to attachment structure 100 except that end 112 of attachment structure 500 is generally formed as a single unitary body with component 32. As such, spring 106 is no longer necessary. Attachment structure 100, attachment structure 500 couples component 32 and circuit board 30 to frame 36 along a single axis.
Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention. For example, although different preferred embodiments may have been described as including one or more features providing one or more benefits, it is contemplated that the described features may be interchanged with one another or alternatively be combined with one another in the described preferred embodiments or in other alternative embodiments. Because the technology of the present invention is relatively complex, not all changes in the technology are foreseeable. The present invention described with reference to the preferred embodiments and set forth in the following claims is manifestly intended to be as broad as possible. For example, unless specifically otherwise noted, the claims reciting a single particular element also encompass a plurality of such particular elements.
