Patent Application
20140087570
The present disclosure generally relates to the field of Peripheral Component Interconnect Express (PCIe) cards and cable connectors, and more particularly to an apparatus for providing a plurality of exit routes to a single type of cable from a PCIe card.
Current systems and methods for exiting a cable, such as a Serial Attached SCSI (“SAS”) cable from a PCIe card may present problems with overextending the bend radius of the SAS cable as it exits the card. If the SAS cable and PCIe card are to be implemented in a variety of ways, it may be necessary to use different cable types and card configurations to accommodate the different system implementations.
Therefore, there exists a need for improved methods and systems for configuring a PCIe card and cable connectors to accommodate different exit routes for SAS cables.
The present disclosure is directed to an apparatus configured for providing a plurality of exit routes to a single type of cable. The apparatus includes a board configured to have a notch. The notch is dimensioned to have a first predetermined distance from a lowest edge of the notch to a pin A1 location on the board and a second predetermined distance from an edge of the board to the pin A1 location. The apparatus also includes a plurality of connectors configured for receiving a cable of the plurality of the single type of cable. Each cable is inserted into a respective connector, and each cable exits the board through the notch. The cable may exit the board through a plurality of routes without requiring changes to the dimension of the board or placement of the connectors.
The present disclosure is also directed to an apparatus configured for providing a plurality of exit routes to a single type of cable. The apparatus includes a board configured for providing a plurality of exit routes to a single type of cable. The board includes a notch which is configured to have a predetermined distance from a lowest edge of the notch to a pin A1 location on the board, as well as a second predetermined distance from an edge of the board to pin A1. The apparatus also includes a connector configured for receiving the single type of cable. The single type of cable connects to the connector and exits the board through the notch of the board, and may take a plurality of exit routes without requiring changes to the board configuration or cable type.
The present disclosure is also directed to a method for connecting a plurality of cables, a plurality of connectors, and a board. The method includes the step of housing the plurality of connectors on the board. Each connector is configured to receive a cable of the plurality of cables. The method also includes the step of configuring a notch in the board. The notch is dimensioned to allow each cable to exit the board when connected to each connector. The placement of the notch and the connectors in the board allows each cable of the plurality of cables to exit the board via a plurality of routes.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not necessarily restrictive of the present disclosure. The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate subject matter of the disclosure. Together, the descriptions and the drawings serve to explain the principles of the disclosure.
The numerous advantages of the disclosure may be better understood by those skilled in the art by reference to the accompanying figures in which:
Reference will now be made in detail to the subject matter disclosed, which is illustrated in the accompanying drawings.
Referring generally to
The board 102 of the apparatus 100 shown in
The notch 104 is also dimensioned to have a second predetermined distance from an edge 112 of the board 102 to the pin A1 location 110. The second predetermined distance may extend up to a distance that is reasonable for proper placement of each of the plurality of connectors 106.
The apparatus 100 also includes the plurality of connectors 106. Each connector of the plurality of connectors 106 is configured for receiving the single type of cable. In one example, the connectors 106 are 12G miniSAS-HD connectors, configured for receiving 12G Serial Attached Small Computer System Interface (SCSI) cables, although it is contemplated that other connector types and cable types may also be used. For example, a 6G Serial Attached SCSI cable, or a PCIe cable may be used, as well as their corresponding connectors. The plurality of connectors 106 may include four connectors 106 in one embodiment.
The apparatus 100 is configured so that each cable is inserted into a respective connector of the plurality of connectors 106. Each cable exits the board 102 through the notch 104. The cables may exit the board 102 in several ways without requiring changes to the configuration of the apparatus 100, the dimension of the board 102, or the placement of the connectors 106. For example, the cables may exit the board 102 via a side out exit route, rear exit route, front exit route, or a straight exit route, without changing the board 102 or placement of the connectors 106.
The apparatus 100 may also be configured to provide a clearance between the plurality of connectors 106 and the notch 104. The clearance may be present on both sides of the plurality of connectors 106. The length of the notch 104 may be equal to a sum of a width of the plurality of connectors plus the clearance dimension on each side of the plurality of connectors.
In one example, the apparatus 100 shown in
The apparatus 100 shown in
A 12G Serial Attached SCSI cable is inserted into each of the four 12G miniSAS-HD connectors 106, and each 12G Serial Attached SCSI cable exits the PCIe card 102 through the notch 104. The use of the apparatus 100 facilitates the exit of the 12G Serial Attached SCSI cable from the PCIe card 102 via any one of a plurality of exit routes. The exit route may include a side out exit route, rear exit route, front exit route, and a straight exit route.

Referring generally to
The board 302 includes a notch 304 which is dimensioned to facilitate the plurality of exit routes for the single type of cable without requiring changes to the dimensions of the board 302 for different exit routes or a change in cable type to accommodate a different exit route. The notch 304 of the board 302 is dimensioned to have a predetermined distance from a lowest edge of the notch 308 to a pin A1 location 310. This predetermined distance may range from 0.758 inches up to 0.760 inches in one example.
The notch 304 is also dimensioned to have a second predetermined distance from an edge 312 of the board 102 to the pin A1 location 310. The second predetermined distance may extend up to a distance that is reasonable for proper placement of the connector 306. In one embodiment, the second predetermined distance may range from 1.246 inches up to 1.250 inches. In one embodiment, the second predetermined distance is 1.246 inches.
The apparatus 300 is configured so that the cable is inserted into the connector 306 and exits the board 302 through the notch 304. The cable may exit the board 302 in several ways without requiring changes to the configuration of the apparatus 300, the dimension of the board 302, or the placement of the connector 306.

The step of configuring a notch in the board 402 of the method 400 may include configuring the notch to have a predetermined distance from a lowest edge of the notch to a pin A1 location equal to approximately 0.758 inches, and configuring the notch to have a second predetermined distance from an edge of the board to a pin A1 location equal to approximately 0.488 inches.
The method 400 can be used for connecting a plurality of cables, a plurality of connectors, and a board. The board may include a Peripheral Component Interconnect Express card, and the plurality of cables may include a plurality of a single type of 12G Serial Attached SCSI cables.
