Integrated guiding and camming system for board

[0001] The present disclosure relates in general to connectors for information handling system components, and more particularly to connectors that facilitate component insertion and extraction.

[0002] As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or 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.

[0003] Information handling systems often utilize a number of modules (e.g., servers) mounted in racks. Proper insertion of these devices into their respective racks requires physical and electrical connections between the device and the system. However, an individual inserting the device may be required to apply force directly to the server, either through pushing or pulling, to connect male and female connectors. In addition, to insert or remove a device from a system, an individual may be required to apply force to the device in a direction non-parallel to the connector. Consequently, connector pins may be damaged (e.g., bent) by the application of such forces. In addition, damage to servers, racks and other components may result from the application of oblique forces during module insertion and/or removal.

[0004] Accordingly, a need has arisen for improved connectors that allow modules to be connected with reduced risk of damage to connectors and/or other system components. The present disclosure relates to connectors that facilitate module insertion and extraction. In accordance with the teachings of the present disclosure, the disadvantages and problems associated with damaged connectors and other components associated with installation and removal of modular components have been substantially reduced or eliminated.

[0038] Install surface 117 may be configured to contact camming surface 164 (e.g., a portion of camming surface 164 proximal to base 155). Install surface 117 may be contoured to contact camming surface 164 with increasing force as camming end is rotated about axis R-R by arm 120. Remove surface 118 may be configured to contact camming surface 164 (e.g., a portion of camming surface 164 distal to base 155). Remove surface 118 may be contoured to contact camming surface 164 with increasing force as camming end is rotated about axis R-R by arm 120. Install surface 117 and remove surface 118 may be configured such that only one of install surface 117 and remove surface 118 contacts camming surface 164 at a time.

[0039] Projections 119a and 119b may extend laterally from opposite sides of camming end 115 and may be configured to engage detents 142, 143, 147, and 148. More specifically, projections 119a and 119b may respectively engage detents 142 and 147 when cam lever 110 (e.g., camming end 115) is in a closed position.

Axel projection 116a is shown rotatably engaged with cam riding surface 141 and projection 119a is releasably engaged with closed detent 142.

[0047] FIG. 1E illustrates an example cam unit configured to facilitate connection of information handling system components. As depicted in FIG. 1E, cam unit 100 is in a closed position and may comprise cam lever unit 105 and cam platform 150. Install surface 116 is shown contacting cam surface 164 on the side proximal to base 155. In addition, guide pin 165 is shown fully engaged with guide receptacle 131 and the underside of base 130 is adjacent to (e.g., contacts) the upper side of base 155. Projection 119a is releasably engaged with closed detent 142.

[0048] FIG. 2A illustrates an example information handling system card prepared to engage an example information handling system board. As depicted in FIG. 2A, information handling system card 270 may comprise lever units 205a and 205b, support 271, and female connector 275. As depicted in FIG. 2, information handling system board 280 may comprise cam platforms 250a and 250b, support 281, and male connector 285.

[0049] Lever units 205a and 205b may be fixed to opposing ends of a common side of support 271. Female connector 275 may be fixed to the same side and positioned between lever units 205a and 205b. Cam platforms 250a and 250b may be fixed to opposing ends of a common side of support 281. Male connector 285 may be fixed to the same side and positioned between cam platforms 250a and 250b. Lever unit 205a and cam platform 250a may be positioned on support 271 and support 281 respectively so as to align (e.g., operably align) with each other, for example, when female connector 275 and male connector 285 align.

[0050] Connectors 275 and 285, according to some embodiments, may comprise a connector selected from peripheral component interconnect (PCI), accelerated graphics port (AGP), small computer system interface (SCSI), and combinations thereof.

[0051] In operation, cam levers 210a and 210b may be in an open position (e.g., with projections 219a and 219b engaged with open detents 243 and 248 respectively) and/or placed in an open position prior to connecting information handling system components. In addition, guide pins 265 may be approximately aligned with their respective guide receptacles 231.

[0052] FIGS. 2B and 2C illustrate the example information handling system card 270 and example information handling system board 280 shown in FIG. 2A. As depicted in FIG. 2B, information handling system card 270 is partially engaged with information handling system board 280. For example, guide pins 265 are partially inserted into respective guide receptacles 231, thereby bringing connectors 275 and 285 into alignment. In addition, arms 220 of each cam lever 210 are partially rotated toward a closed position ambulating their respective camming ends 215 into a position of partially engaging cam shafts 263. Specifically, rotating arms 220 back toward an open position will cause remove surfaces 218 to contact their respective camming surfaces 264 (e.g., distal to base 155). Continued application of force to open arms 220 is translated by camming ends 215 to movement tending to separate connectors 275 and 285 (FIG. 2A). On the other hand, rotating arms 220 toward a closed position will cause install surfaces 217 to contact their respective camming surfaces 264 (e.g., proximal to base 155). Continued application of force to close arms 220 is translated by camming ends 215 to movement tending to press together connectors 275 and 285 and complete their engagement (FIG. 2D). FIG. 2C illustrates an exploded view of lever unit 205b and cam platform 250b shown in FIG. 2B.

[0053] FIG. 2D illustrates the example information handling system card 270 and example information handling system board 280 shown in FIGS. 2A and 2B. As depicted in FIG. 2C, information handling system card 270 is completely engaged with information handling system board 280 (e.g., female connector 275 is fully engaged with male connector 285 and/or projections 119a and 119b are engaged with closed detents 142 and 147 respectively). Metrics for full engagement of connectors 275 and 285 may be electrical and/or optical connection of a desirable number of pins between connectors 275 and 285. In some embodiments, it may be desirable and/or required include a plurality of connectors (e.g., male and/or female) on card 270 and a plurality (e.g., a corresponding plurality of connectors (e.g., male and/or female) on board 280.

[0054] While the ratio of cam units to connector pairs (one male and one female) may be 1 unit to 1 pair (1:1), it may be desirable to use two or more cam units per connector pair.

[0055] FIG. 3 illustrates a flow chart of an example method 390 for engaging connectors, in accordance with the present disclosure. In one embodiment, method 390 comprises aligning 391 a first connector and lever unit (or cam platform) on a first information handling system component with a second connector and cam platform (or lever unit) on a second information handling system component, inserting 392 at least a portion of a guide pin into a guide receptacle, moving 393 at least a portion of a camming end of a cam lever across a camming surface of a cam shaft, and translating 394 the lateral movement across the camming surface into vertical movement to press together first and second connectors.

[0056] According to one embodiment, method 390 begins at step 391. As noted above, teachings of the present disclosure may be implemented in a variety of configurations of system 100. As such, the preferred initialization point for method 390 and the order of the steps 391-394 comprising method 390 may depend on the implementation chosen.

[0057] At step 391, a first connector on a first information handling system component is generally aligned with a second connector on a second information handling system component. A first connector may be a male connector or a female connector in some embodiments. A second connector may be a male connector or a female connector with the proviso that the second connector is compatible with the first connector. Step 391 may include aligning 391 a first connector (e.g., female connector 85) and cam platform 50 on board 80 with a corresponding second connector (e.g., male connector 75) and lever unit 5 on card 70.

[0058] At step 392, at least a portion of guide pin 65 (e.g., guide pin cap 67) is inserted into guide receptacle 31 to substantially align lever unit 5 and cam platform 50, which aligns connectors 75 and 85. Step 392 may comprise inserting 392 at least a portion of a first guide pin 65 into a first guide receptacle 31 and a second guide pin 65 into a second guide receptacle. Inserting guide pin 65 into guide receptacle 31 may tend to bring at least a portion of camming end 15 into contact with at least a portion of camming surface 64. Additional camming units may be used as desired or required.

[0059] At step 393, moving at least a portion of a camming end across a camming surface may include rotating arm 20 about axel 16 to ambulate camming end 15 and move install surface 17 (e.g., generally laterally) across camming surface 64. In some embodiment, lever units may be paired such that first camming end 15 is ambulated to move first install surface 17 across first camming surface 64 by clockwise rotation of first arm 20 and second camming end 15 is ambulated to move second install surface 17 across second camming surface 64 by counter-clockwise rotation of second arm 20.

[0060] At step 394, lateral movement of camming end 15 across install surface 17 is translated into vertical movement to press together first and second connectors. For example, the shapes (contours) of install surface 17 and/or camming surface 64 (e.g., a portion proximal to base 55) may be configured to translate this lateral movement into vertical movement tending to press together lever unit 5 and cam platform 50 and, consequently, items attached to lever unit 5 (e.g., female connector 85) and cam platform 50 (e.g., male connector 75).

[0061] FIG. 4 illustrates a flow chart of an example method 495 for disengaging connectors, in accordance with the present disclosure. In one embodiment, method 495 comprises moving 496 at least a portion of a camming end of a cam lever across a camming surface of a cam shaft, translating 497 the lateral movement across the camming surface into vertical movement to press a first connector and lever unit (or cam platform) on a first information handling system component apart from a second connector and cam platform (or lever unit) on a second information handling system component, and removing 498 a guide pin from a guide receptacle.

[0062] According to one embodiment, method 495 begins at step 496. As noted above, teachings of the present disclosure may be implemented in a variety of configurations of system 100. As such, the preferred initialization point for method 495 and the order of the steps 496-498 comprising method 495 may depend on the implementation chosen.

[0063] At step 496, moving at least a portion of a camming end across a camming surface may include rotating arm 20 about axel 16 to ambulate camming end 15 and move remove surface 18 (e.g., generally laterally) across camming surface 64 (e.g., distal to base 55). In some embodiment, lever units may be paired such that first camming end 15 is ambulated to move first remove surface 18 across first camming surface 64 by clockwise rotation of first arm 20 and second camming end 15 is ambulated to move second remove surface 18 across second camming surface 64 by counter-clockwise rotation of second arm 20.

[0064] At step 497, lateral movement of camming end 15 across remove surface 18 is translated into vertical movement to press apart first and second connectors. For example, the shapes (contours) of remove surface 18 and/or camming surface 64 (e.g., a portion distal to base 55) may be configured to translate this lateral movement into vertical movement tending to press apart lever unit 5 and cam platform 50 and, consequently, items attached to lever unit 5 (e.g., female connector 85) and cam platform 50 (e.g., male connector 75).

[0065] At step 498, removing a guide pin from a guide receptacle may include backing guide pin 65 out (e.g., entirely out) of guide receptacle 31. This may be desired and/or required to free first and second information handling system components from each other.

[0066] Methods 390 and/or 495 may be implemented using system 0 (e.g., lever unit 5 and/or cam platform 50) or any other system operable to implement method 200. In certain embodiments, methods 390 and/or 495 may be implemented partially or fully in software embodied in computer-readable media.

[0067] Although the present disclosure has been described in detail, it should be understood that various changes, substitutions, and alterations can be made hereto without departing from the spirit and the scope of the disclosure as defined by the appended claims.
