## Background
BACKGROUND
The present disclosure relates generally to information handling systems, and more particularly to a method and apparatus for mounting a card connector in an information handling system.
As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.
Card connectors are used in information handling systems for allowing the coupling of cards to the information handling system. The card connectors are typically mounted and electrically coupled to a connector coupling section on a circuit board in the information handling system to allow cards to be electrically coupled to components in the information handling system. The mounting of these card connectors raises a number of issues.
Conventional card connectors typically include a pair of mounting pegs which are spaced apart and extend from a centrally located position on the bottom surface of the card connector. For example, typical ×16 PCI-Express connectors and ×8 PCI-Express connectors each include a pair of mounting pegs which are centrally located on the connectors such that the ×8 PCI-Express connector cannot be exchanged with a ×16 PCI-Express connector on the connector coupling section of the board because one of the ×8 PCI-Express connector mounting pegs will be positioned in the middle of the ×16 PCI-Express connector section signal field. Locating the mounting pegs in this manner does not permit the co-location of different sized card connectors or flexible design, which increases costs.
Accordingly, it would be desirable to provide a method and apparatus for mounting a card connector absent the disadvantages found in the prior methods discussed above.
SUMMARY
According to one embodiment, a card connector mounting apparatus is provided that includes a base including a card coupler and having a plurality of electrical coupling members positioned on a bottom surface of the base, a first base side positioned along the length of the base, and a first board mounting member extending from the first base side and positioned adjacent the bottom surface.
A principal advantage of this embodiment is that a plurality of different sized card connectors may be mounted to the same connector coupling section on the board, allowing flexible designs and increasing efficiency.

A connector mounting member 310 is defined by the board 300, located on the board surface 302 in the connector coupling section 304, and positioned between the first section side 304c and the second section side 304d, between the plurality of electrical connector couplers 306, and adjacent the second section end 304b.

Card connector 100 and card connector 200 are different size card connectors and, in an embodiment, may include a ×16 PCI-Express connector and a ×8 PCI-Express connector, respectively.
Referring now to FIGS. 2b, 5a, 5b, and 5c, the method 400 proceeds to step 406 where a desired card connector size is determined. The determination of the desired card connector size will depend on the bandwidth needed for the card to be coupled to the board 300. In an embodiment, a relatively larger bandwidth will be needed for the card, and the card connector 100 will be determined to be the appropriate sized card connector. The method 400 then proceeds to step 408 where card connector 100 is mounted and electrically coupled to the board 300. The card connector 100 is positioned over the connector coupling section 304 on the board surface 302 such that first base end 102a is lined up with first section end 304a, second base end 102b is lined up with second section end 304b, first base side 102c is lined up with first section side 304c, second base side 102d is lined up with second section side 304d, board mounting member 108 is lined up with connector coupling member 310, and board mounting member 110 is lined up with connector coupling member 312a. The card connector 100 may then be lowered onto the base 300 such that board mounting member 108 engages connector coupling member 310 and board mounting member 110 engages connector coupling member 312a, resulting in the mounting of the card connector 100 to the board 300. The electrical coupling members 106 may then be electrically coupled to the electrical connector couplers 306 using methods known in the art such as, for example, soldering, resulting in the electrical coupling of the card connector 100 to the board 300. In an embodiment, the electrical coupling of the card connector 100 to the board 300 electrically couples the card connector 100 to the information handling system component 308.
However, referring now to FIGS. 3b, 5a, 5d, and 5e, in an embodiment, a relatively smaller bandwidth will be needed for the card, and the card connector 200 will be determined to be the appropriate sized card connector. The method 400 then proceeds to step 408 where card connector 200 is mounted and electrically coupled to the board 300. The card connector 200 is positioned over the connector coupling section 304 on the board surface 302 such that second base end 202b is lined up with second section end 304b, first base side 202c is lined up with first section side 304c, second base side 202d is lined up with second section side 304d, board mounting member 208 is lined up with connector coupling member 310, and board mounting member 210 is lined up with connector coupling member 312b.

Thus, a card connector mounting system is provided which allows a plurality of different sized card connectors such as, for example, the card connectors 100 and 200, to be connected to the same connector coupling section such as, for example, the connector coupling section 304. In an embodiment, the plurality of different sized card connectors may include ×1 PCI-Express connectors, ×2 PCI-Express connectors, ×4 PCI-Express connectors, ×8 PCI-Express connectors, ×12 PCI-Express connectors, ×16 PCI-Express connectors, ×32 PCI-Express connectors, ×64 PCI-Express connectors, and a variety of other card connectors known in the art.

Card connector 500 and card connector 600 are different size card connectors and, in an embodiment, may include a ×16 PCI-Express connector and a ×8 PCI-Express connector, respectively.
Referring now to FIGS. 6b, 9a, 9b, and 9c, the method 800 proceeds to step 806 where a desired card connector size is determined. The determination of the desired card connector size will depend on the bandwidth needed for the card to be coupled to the board 700. In an embodiment, a relatively larger bandwidth will be needed for the card, and the card connector 500 will be determined to be the appropriate sized card connector. The method 700 then proceeds to step 808 where card connector 500 is mounted and electrically coupled to the board 700. The card connector 500 is positioned over the connector coupling section 304 on the board surface 302 such that first base end 102a is lined up with first section end 304a, second base end 102b is lined up with second section end 304b, first base side 102c is lined up with first section side 304c, second base side 102d is lined up with second section side 304d, board mounting member 108 is lined up with connector coupling member 310, board mounting member 110 is lined up with connector coupling member 312a, and board mounting member 502 is lined up with connector coupling member 702a.

The electrical coupling members 106 may then be electrically coupled to the electrical connector couplers 306 using methods known in the art such as, for example, soldering, resulting in the electrical coupling of the card connector 500 to the board 700. In an embodiment, the electrical coupling of the card connector 500 to the board 700 electrically couples the card connector 500 to the information handling system component 308.
However, referring now to FIGS. 7b, 9a, 9d, and 9e, in an embodiment, a relatively smaller bandwidth will be needed for the card, and the card connector 600 will be determined to be the appropriate sized card connector.

In an embodiment, the electrical coupling of the card connector 600 to the board 700 electrically couples the card connector 600 to the information handling system component 308. In an embodiment, the card connector 500, card connector 600, and board 700 provide a card connector mounting system. Thus, a card connector mounting system is provided which allows a plurality of different sized card connectors such as, for example, the card connectors 500 and 600, to be connected to the same connector coupling section such as, for example, the connector coupling section 304.
