Connectors can be used to connect electronic components (e.g., server components, printed circuit boards, memory modules, etc.) within servers in a computing system or network to one another. Multiple portions (e.g., terminals) of the connector may be connected to an electronic component. The connector can transmit information (e.g., a signal) between the electronic components.
Flexibility of electronic component placement has become important for next generation server designs and other high density applications. Some approaches to connecting these electronic components via a connector include using solid block-type connectors (e.g., array connectors) placed in locations not blocking airflow to downstream components. However, as bus speeds increase and routing distances decrease, solid block-type connectors have been placed in front of electronic components (e.g., banks of memory).
Placing connectors in front of electronic components may create a cooling dead zone and may limit the ability of fans to adequately cool electronic components downstream. This may lead to limitations on the type of electronic components a system can support downstream of connectors, the layout of electronic components in a system, and/or the flexibility of connector placement in a system.
In contrast, examples of the present disclosure allow for the inclusion of cooling slots also known as gaps, in connectors. This can reduce the impact of placing a connector in front of electronic components, as compared to other approaches, by allowing airflow (e.g., direct airflow) to electronic components, and in particular, to downstream electronic components.
Cooling slots added to connectors in accordance with the present disclosure can reduce the effect of placing a connector in front of electronic components. The resulting distributed air path can allow for greater airflow to cool electronic components downstream (e.g., directly downstream) as compared to other approaches. For instance, a connector in accordance with the present disclosure may be placed in front of banks of electronic components providing airflow targeted to specific electronic components within the bank. Loss of cooling capacity can be reduced when compared to the placement of a solid connector between banks of electronic components.
Connector 100 can include a first portion 102 and a second portion 104. Portions 102 and 104 can also be referred to as mating portions, as they can be connected or “mated” to electronic components. Portions 102 and 104 may be separated, for instance, at separation line 108, should the connected electronic components be pulled apart. For instance, portion 102 may be connected to a first electronic component that is separated from a second electronic component connected to the portion 104. When separated, portion 102 stays connected to the first electronic component, while portion 104 stays connected to the second electronic component.
Slots 106-1, 106-2, . . . , 106-n can be included in connector 100 to allow for airflow to pass through the connector and downstream to electronic components. Slots 106-1, 106-2, . . . , 106-n can, in some instances, be located in just portion 104, just portion 102, or can be in both portions 102 and 104. In some examples, slots 106-1, 106-2, . . . , 106-n include gaps (e.g., air gaps) between groups of wafers inside of connector 100. For instance, electrical connections between a mezzanine card and a motherboard can be made on wafers inside of the connector (e.g., connector 100). These connections can be arranged in such a way that there are gaps between groups of wafers. These gaps, when used as cooling slots, (e.g., slots 106-1, 106-2, . . . , 106-n) can improve airflow through and around the connector. In addition, connector 100 including slots 106-1, 106-2, . . . , 106-n can have the same number of connections as a connector with no slots (e.g., solid block connector), for instance.
In a number of examples, connector 200 can include a backplane connector. For instance, a connector within a backplane system can include slots (e.g., slots 206-1, 206-2, . . . , 206-n) allowing for airflow through and around the connector. One, two, or more of the connectors within the backplane system can include slots. In an example, a backplane system can be used as a backbone to connect printed circuit boards. At least one connector within the system can include slots (e.g., slots 206-1, 206-2, . . . , 206-n), which can increase the airflow to printed circuit boards located behind the connector, particularly in comparison to airflow to printed circuit boards behind a solid block connector. While used in this example, electronic components included in the backplane system are not limited to printed circuit boards. In addition, the backplane system may be active and/or passive.
Connector 200 can be a midplane connector in a number of examples. A midplane connector can include electronic components connected to both sides of the midplane connector. For instance, modules, cards, devices, and other electronic components can be connected to either side of a midplane connector. By implementing slots (e.g., slots 206-1, 206-2, . . . , 206-n) into a midplane connector, these modules, cards, devices, and other electronic components can receive better airflow, as compared to modules, cards, devices, and other electronic components connected to solid block connectors. Furthermore, electronic components downstream of the midplane connector can be exposed to increased airflow. In a number of examples, slotted backplane and midplane connectors in accordance with the present disclosure can prevent localized dead zones present with the use of solid block backplane and midplane connectors.

The example illustrated in
Connector 400 can include a first portion 402 that may be connected to electronic component 420, and second portion 404 that may be connected to electronic component 422. In such an example, should electronic component 420 be separated from electronic component 422, connector 400 may separate at 408. This would result in portion 402 remaining connected to electronic component 420, and portion 404 remaining connected to electronic component 422.
Connector 400 can include slots 406-1, 406-2, . . . , 406-n that allow airflow through and around connector 400. The airflow through and around connector 400 can allow for increased airflow to electronic components. For instance, in the example illustrated in
This increased airflow via slots 406-1, 406-2, . . . , 406-n in connector 400 can also result in a decrease in pressure drop within a server as compared to solid block connectors. For example, inserting an obstruction to airflow creates an increase in airflow pressure drop. By introducing slots 406-1, 406-2, . . . , 406-n into connector 400, the pressure drop across the connector is less than a similar sized connector without slots. A decrease in pressure drop results in fan power savings. Further, because airflow is increased, fan power consumption within system 416 (e.g., within server blade 418) can be reduced. Electronic component placement can be more flexible with a slotted connector (e.g., connector 400) as compared to solid block connectors, as airflow to electronic components located in different locations may be attainable because of the slotted connector. For instance, locations of electronic components within server blade 418 may be flexible, based on the location of slots 406-1, 406-2, . . . , 406-n (e.g., locations of gaps between wafers).
Connector 400 may also be less expensive to implement as compared to multiple solid block connectors arranged in a similar footprint. One connector may be slotted and installed, rather than installing multiple, small, discreet connectors in a similar footprint. In addition, maintaining one connector with slots, as opposed to multiple connectors can allow for maintenance of alignment, structural integrity, and speed characteristics, signal characteristics, and pin-to-pin characteristics of the connector (e.g., of the original connector). Connector 400 may also be more mechanically robust compared to the multiple connectors. For example, reducing the number of connectors in a server, system, etc. can reduce the risk of connector failure, and in turn, can result in an increase in mechanical robustness over a server, system, etc. using multiple connectors. In some instances, connector 400 may also have a smaller footprint than the multiple connectors, resulting in more flexibility and better airflow, among other benefits.
