The disclosure relates to cable interconnects for electrical cables.
In a data center environment, cables are the main method of interconnect between systems. Service and usability of the systems are an ongoing concern. A typical data center may have one or more “hot” aisles and one or more “cold” aisles adjacent to the system equipment. To cool the equipment running in the data center, airflow is created from the cold aisle through the equipment to the hot aisle. The hot air in the hot aisle is then directed to be cooled via an air cooling unit for supply back to the cold aisles, or the hot air can be vented into the ambient environment outside of the space in which the equipment is housed.
Servicing of the data center equipment typically has to occur from both hot and cold aisles. The equipment may be inserted into a rack system or other structure designed to house the equipment from the cold aisle side, and the data and other cables to be connected to the equipment are typically coupled to the equipment from the hot aisle side. Because of the amount of heat generated by the data center equipment, the temperature in the hot aisle can be very uncomfortable for the technician or other personnel tasked to be in the hot aisle to connect or disconnect cabling from the equipment.
Overview
In one example, the disclosure is directed to a connector bezel configured to guide engagement of a male mating connector of a cable with a female mating connector. The connector bezel comprises a front plate having a main opening formed therein configured to allow passage of the male mating connector therethrough and a rear assembly attached to the front plate. The rear assembly comprises a plurality of walls forming a cable connector opening therethrough and a rear opening formed in the rear assembly configured to allow passage of the female mating connector therethrough. The cable connector opening is fluidly coupled with the main opening and with the rear opening.
In another example, the disclosure is directed to a method of manufacturing a connector bezel comprises forming a main opening in a front plate, the main opening configured to allow passage of the male mating connector therethrough and attaching a plurality of walls to the front plate. The plurality of walls forming a cable connector opening fluidly coupled with the main opening. The method also comprises forming a rear opening configured to allow passage of the female mating connector therethrough, the rear opening fluidly coupled with the cable connector opening.
In another example, the disclosure is directed to a cable interconnect system comprises an electrical cable comprising a male connector, a circuit board, and a female connector attached to the circuit board and configured to mate with the male connector. The cable interconnect system also comprises a connector bezel comprising a front plate having a main opening formed therein configured to allow passage of the male connector therethrough and a rear assembly attached to the front plate. The rear assembly comprises a plurality of walls forming a cable connector opening therethrough and a rear opening formed in the rear assembly configured to allow passage of the female connector therethrough. The cable connector opening is fluidly coupled with the main opening, and the rear opening is fluidly coupled with the cable connector opening.

Referring to
As illustrated in
Rear assembly 114 includes a plurality of side walls 136, 138 and a bottom wall 140 that, together with top wall 134, form a cable connector opening 142 into which male mating connector 104 couples with female mating connector 108. Extending at least from top and side walls 134-138 are beveled walls 144 to help guide, if needed, female mating connector 108 into a rear opening 146 that communicates via top, side, and bottom walls 134-140 with main opening 116 by way of the cable connector opening 142. As such, cable connector opening 142 is fluidly coupled to both main opening 116 and rear opening 146. A plurality of ribs 148 strengthen and stabilize front plate 112 and walls 134-144.
A plurality of flexible securing members 150 positioned adjacently to side walls 136, 138 secure connector bezel 102 to a panel wall (as illustrated and discussed in
An alignment assembly 152 coupled to bottom wall 140 aids the alignment and insertion of female mating connector 108 into cable connector opening 142. Alignment assembly 152 includes a first wall 154 extending perpendicularly away from bottom wall 140. First wall 154 is coupled with bottom wall 140 and may additionally be coupled with front plate 112 for added stability. One or more circuit board support walls 156 extend from first wall 154 such that a gap 158 between circuit board support walls 156 and bottom wall 140 allows circuit board 110 to pass thereinto. A groove 160 formed in circuit board 110 is aligned with female mating connector 108 such that engagement of the circuit board 110 with the alignment assembly 152 via groove 160 during movement of circuit board 110 in an insertion or installation direction aligns the female mating connector 108 with the cable connector opening 142. Contrary to the ability of the male mating connector 104 to be locked with connector bezel 102, female mating connector 108 does not include locking hardware or elements able to directly engage female mating connector 108 with connector bezel 102 in a locking arrangement. Thus, removal of circuit board 110 away from connector bezel 102 in a removal or uninstallation direction opposite the insertion direction also removes female mating connector 108 from connector bezel 102 with resistance against uninstallation provided by a friction fit between male mating connector 104 and female mating connector 108. Further discussion of the engagement of circuit board 110 and alignment assembly 152 is found below in
The end portion 118 of male mating connector 104 extends into cable connector opening 142, and in the embodiment shown, substantially traverses cable connector opening 142 to reach an end of the bottom wall 140. In this manner, male mating connector 104 may be fully engaged with female mating connector 108 (
Module 168 is shown as an enclosure housing a circuit board assembly 184 having a female mating connector 186 coupled thereto. Module 164 may be inserted into cabinet 164 via one or more shelves 188 as shown or via a rail system such as rail system 174, for example. Similar to module 166, module 168 is locked into cabinet 164 via a cabinet locking system 190 that secures module 166 within cabinet 164 to prevent disengagement of female mating connector 172 from the male mating connector 192 of a cable 194 when both are inserted into the same connector bezel 196.
Once locked into their respective connector bezels 182, 196, male mating connectors 178, 192 remain connected thereto even during removal and insertion of modules 166, 168 into cabinet 164. Since female mating connectors 172, 186 are not locked to their respective connector bezels 182, 196, they travel with modules 166, 168 and are disengaged from connector bezels 182, 196 and male mating connectors 178, 192 when the entire module 166, 168 is removed from the cabinet 164. When modules 166, 168 are inserted into cabinet 164 and locked into place via cabinet locking systems 176, 190, female mating connectors 172, 186 are securely coupled to male mating connector 178, 192 and cannot be disengaged without removal of modules 166, 168 or detachment of male mating connectors 178, 192 from connector bezels 182, 196.
Cabinet 164 includes a panel wall or backplane 198 into which connector bezel 182, 196 are inserted.
As shown, modular systems 224 include panel walls 240 having connector bezels 242 installed therein. Modules 226 mounted and installed in modular systems 224 have circuit boards 244 with female mating connectors as described herein. Cables 246 are connected to the female mating connectors as described above and modules 226 with other modules 226 or other equipment as needed.
Embodiments of the disclosure herein allow a technician performing maintenance on one or more modules 226 to spend less time exposed to the hot air in the hot aisles 236 by allowing disconnection of the modules 226 from the cables 246 from within the cold aisles 228. Additionally, since the female mating connector and corresponding cable connection are located adjacently to the hot aisle 236, internal re-routing to allow a cable connection from the front side near the cold aisle 228 may be avoided. Thus, a reduction of real estate within each module 226 due to such internal re-routing is avoided.
Various examples of the disclosure have been described. Any combination of the described systems, operations, or functions is contemplated. These and other examples are within the scope of the following claims.
