BACKGROUND
The present disclosure relates generally to information handling systems, and more particularly to a connector release system for releasing a connector secured to 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 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.
Information handling systems such as server devices, networking devices, storage system, and/or other computing devices known in the art, are often coupled together using cables via connectors that are included on those cables and that couple to ports on the computing devices. For example, many computing devices are coupled together via RJ-45 cables that include RJ-45 connectors, which were developed as a standardized telecommunications coupling interface for connecting telephone networks. Such RJ-45 connectors include an RJ-45 connector release tab (e.g., a plastic tab extending from the RJ-45 connector) having an RJ-45 connector securing feature that engages the port on the computing device when the RJ-45 connector is positioned in that port, which operates to secure the RJ-45 connector in that port. A user may then remove that RJ-45 connector from that port by pressing the RJ-45 connector release tab with their finger in order to move that RJ-45 connector release tab, and with it the RJ-45 connector securing feature, such that the RJ-45 connector securing feature disengages from the port on the computing device, which allows the user to remove the RJ-45 connector from that port.
However, one of skill in the art in possession of the present disclosure will appreciate that the conventional RJ-45 connectors discussed above suffer from a number of issues. For example, RJ-45 connector release tabs often breaks off of the RJ-45 connector when a user attempts to actuate them to remove the RJ-45 connector from a port, which may prevent that RJ-45 connector from being subsequently secured to ports (e.g., when the RJ-45 connector securing feature breaks off with that RJ-45 connector release tab) or may require a tool (e.g., a screwdriver) in order to remove that RJ-45 connector from a port that it is subsequently secured to (e.g., when the RJ-45 connector securing feature remains after that RJ-45 connector release tab breaks off), and typically results in the corresponding RJ-45 cable being replaced, or in some cases connectivity issues/support calls when subsequently used in a port due to the issues described above. In another example, some ports on computing devices may be recessed and/or otherwise difficult to access, making the RJ-45 connector release tab (which is positioned immediately adjacent the port when the RJ-45 connector is secured to the port) difficult to access in order to remove its RJ-45 connector from those ports. In yet another example, the RJ-45 connector release tab mechanism/operation described above has ergonomic issues that can lead to hand fatigue, particularly is situations where a large number of RJ-45 connectors must be removed from corresponding ports in the same time period (e.g., when switch device(s) are decommissioned).
Accordingly, it would be desirable to provide a connector release system that addresses the issues described above.

In the specific examples provided below, the communication system 208 in the computing device 200 includes ports 208a, 208b, 208c, and up to 208d that are provided by female Ethernet/networking ports that receive RJ-45 connectors, but that may be provided by other types of ports while remaining within the scope of the present disclosure as well However, while a specific computing device 200 has been illustrated and described, one of skill in the art in possession of the present disclosure will recognize that computing devices (or other devices operating according to the teachings of the present disclosure in a manner similar to that described below for the computing device 200) may include a variety of components and/or component configurations for providing conventional computing device functionality, as well as the functionality discussed below, while remaining within the scope of the present disclosure as well.
Referring now to FIGS. 3A, 3B, and 3C, an embodiment of a cable connector system 300 is illustrated that includes a connector base 302 having a front end 302a that is configured to be inserted in a port (e.g., one of the ports 208a-208d discussed above with reference to FIG. 2), and a rear end 302b that is located opposite the connector base 302 from the front end 302a. One of skill in the art in possession of the present disclosure will recognize that the connector base 302 is illustrated and described herein as an RJ-45 connector base, but will appreciate that other connector bases will fall within the scope of the present disclosure as well. A cable 304 extends from the second end 302b of the connector base 302, and one of skill in the art in possession of the present disclosure will recognize how the cable 304 may be coupled to the connector base 302 such that wiring and/or other communication conduits that extend through the cable 304 are coupled to wiring and/or other communication conduits that extend through the connector base 302, as well as to port connectors (not illustrated) that are included on or adjacent the first end 302a of the connector base 302. One of skill in the art in possession of the present disclosure will recognize that the cable 304 is illustrated and described herein as an Ethernet cable (i.e., a networking cable with RJ-45 connectors), but will appreciate that other cables will fall within the scope of the present disclosure as well.
A connector release tab 306 extends from the connector base 302 via a connector base connection 306a to the first end 302a of the connector base 302, and one of skill in the art in possession of the present disclosure will recognize how the connector base connection 306a allows the connector release tab 306 to move relative to the connector base 302. For example, the connector base connection 306a may be provided by plastic extension of the connector base 302, although one of skill in the art in possession of the present disclosure will appreciate how other movable connections may be utilized to provide the relative movement of the connector release tab 306 and the connector base 302 while remaining within the scope of the present disclosure. A connector securing feature 308 is included on the connector release tab 306 between the connector base connection 306a and a distal end of the connector release tab 306 that is located opposite the connector release tab from the connector base connection 306a, and one of skill in the art in possession of the present disclosure will appreciate how the connector securing feature 306a is configured to engage a port to secure the connector base 302 in that port, examples of which are described in further detail below.
The cable connector system 300 also include a connector release system that, as illustrated in FIG. 3C and in the specific examples provided herein, includes a connector release linkage having a link 310a that extends from the connector release tab 306 adjacent the distal end of the connector release tab 306 (i.e., opposite the connector release tab 306 from the connector base connection 306a), and a link 310b that extends through a portion of the connector base 302 between the link 310a and a connector release actuator system. In the embodiments illustrated and described herein, one end of the link 310a is pivotally connected to the connector release tab 306, and an opposite end of that link 310a is pivotally connected to an end the link 310b, with an opposite end of that link 310b mounted to the connector release actuator system. However, while a specific example of a connector release linkage is illustrated and described, one of skill in the art in possession of the present disclosure will appreciate how the connector release linkage may be configured in a variety of manners, or how the actuator system may be coupled to the connector release tab 306 in other manners, any of which will fall within the scope of the present disclosure as well.
In the illustrated embodiment, the connector release actuator system includes a first connector release actuator 312a that is accessible on a first side of the connector base 302, a second connector release actuator 312b that is accessible on a second side of the connector base 302, and a third connector release actuator 312c that is accessible on a third side of the connector base 302. However, while a specific example of an connector release actuator system that includes respective connector release actuators accessible on each of the “sides” and the “top” of the connector base 302 are illustrated and described, one of skill in the art in possession of the present disclosure will appreciate that different numbers of connector release actuators in the connector release actuator system may be accessible on the connector base 302 (e.g., only a single connector release actuator may be accessible on one of the “sides” or the “top” of the connector base 302, only two connector release actuators may be accessible on opposite the “sides” of the connector base 302, etc.) while remaining within the scope of the present disclosure as well. In the illustrated embodiment, a biasing member 314 (e.g., a spring in the illustrated example) extends between the connector base 302 and the connector release actuator system, and is configured to bias the connector release actuator system (e.g., the connector release actuator 312a, 312b, and 312c in the illustrated embodiment), the connector release linkage 310a and 310b, and the connector release tab 306 in a “securing” orientation A that is illustrated in FIGS. 3A, 3B, and 3C.
However, while a specific example of a cable connector system 300 including the connector release system of the present disclosure has been illustrated and described with reference to FIGS. 3A, 3B, and 3C, one of skill in the art in possession of the present disclosure will appreciate how other embodiments of the connector release system of the present disclosure may include different features, components, and/or configurations. For example, the embodiments illustrated in FIGS. 3A, 3B, and 3C provide the connector release actuator system (e.g., the connector release actuators 312a, 312b, and 312c in the illustrated embodiment) accessible opposite the second end 302b of the connector base 302 from the cable 304. However, FIG. 3D illustrates how the connector release actuator system may include a connector release actuator base 314 that extends from the second end 302b of the connector base 302 and over a portion of the cable 314 such that the connector release actuator system (e.g., the connector release actuators 312a, 312b, and 312c in the illustrated embodiment) is accessible on the same side of the second end 302b of the connector base 302 as the cable 304. As such, one of skill in the art in possession of the present disclosure will appreciate how a wide variety of modification to the cable connector system 300 will fall within the scope of the present disclosure.
Referring now to FIG. 4, an embodiment of a method 400 for releasing a connector is illustrated. As discussed below, the systems and methods of the present disclosure provide for the release of connectors from ports via a connector release system that includes a connector release linkage that couples the connector release tab on a front end the connector to a connector release actuator located on a rear end of the connector. For example, the connector of the present disclosure may include a connector base with a first end that may be inserted in a port, and a second end located opposite the connector base from the first end. A connector release tab extends from the connector base adjacent the first end and moves relative to the connector base. A connector securing feature on the connector release tab may engage a port to secure the connector base in that port. A connector release system includes a connector release linkage coupled to the connector release tab and extending through the connector base, and a connector release actuator adjacent the second end of the connector base and coupled to the connector release linkage. The connector release actuator may be actuated to move, via the connector release linkage, the connector release tab to disengage the connector securing feature from a port such that the connector base may be removed from that port. As such, issues associated with conventional connectors such as RJ-45 connectors are eliminated.
The method 400 begins at block 402 where a connector on a cable connector system is coupled to a port on a computing device. As will be appreciated by one of skill in the art in possession of the present disclosure, a user of the computing device 200 may wish to connect the computing device 200 to another device and, as such, may connect the cable connector system 300 to the computing device 200 (as well as to that other device). With reference to FIG. 5A, in an embodiment of block 402, a user may position the cable connector system 300 adjacent the port 208c on the computing device 200 such that the front end 302a of the connector base 302 is located adjacent the port 208c, with the biasing member 314 biasing the connector release actuator system (e.g., the connector release actuator 312a, 312b, and 312c in the illustrated embodiment), the connector release linkage 310a and 310b, and the connector release tab 306 in the “securing” orientation A illustrated in FIGS. 3A, 3B, and 3C (as well as in FIG. 5A). With reference to FIGS. 5A and 5B, the user may then move the cable connector system 300 in a direction B and toward the port 208c such that the front end 302a of the connector base 302 enters the port 208c.
The method 400 then proceeds to block 404 where the connector on the cable connector system is secured to the port on the computing device. With reference to FIGS. 5B, 5C, 5D, and 5E, in an embodiment of block 404, continued movement of the cable connector system 300 in the direction B results in the connector securing feature 308 engaging the port 208c, and further movement of the cable connector system 300 in the direction B will overcome the biasing force provided by the biasing member 314 on the connector release actuator system (e.g., the connector release actuator 312a, 312b, and 312c in the illustrated embodiment), the connector release linkage 310a and 310b, and the connector release tab 306 such that the connector release tab 306 moves in a direction C (illustrated in FIG. 5C) until it clears initial securing features on the port 208c to allow the connector base 302 to move further into the port 208c (illustrated in FIG. 5D) until the connector securing feature 308 has moved far enough into the port 208c such that it has cleared final securing features on the port 208c and the connector release tab 306 may move in a direction D (illustrated in FIG. 5E) to allow the connector securing feature 308 to engage those final securing features on the port 208c and secure the connector base 302 in the port 208c. As will be appreciated by one of skill in the art in possession of the present disclosure, with the engagement of the connector securing feature 308 the final securing features on the port 208c will resist movement of the connector base 302 out of the port 208c.
The method 400 then proceeds to block 406 where a connector release actuator is actuated to release the connector on the cable connector system from the port on the computing device. As will be appreciated by one of skill in the art in possession of the present disclosure, a user of the computing device 200 may wish to disconnect the computing device 200 from another device to which it was connected at blocks 402 and 404 as discussed above and, as such, may disconnect the cable connector system 300 from the computing device 200 (as well as from that other device). With reference to FIGS. 6A and 6B, in an embodiment of block 406, the user may apply a force in a direction E on the any of the connector release actuators 312a, 312b, and/or 312c in order to overcome the biasing force provided by the biasing member 314 on the connector release actuator system (e.g., the connector release actuator 312a, 312b, and 312c in the illustrated embodiment), the connector release linkage 310a and 310b, and the connector release tab 306, with operates to move those connector release actuator(s) in the direction E.
As can be seen in FIGS. 6A and 6B, actuation/movement of the connector release actuators 312a, 312b, and/or 312c in the direction E causes moves the link 310b in the direction E, which in turn causes the link 310a to move the connector release tab 306 in a direction F and into a “release” orientation G due to the pivotal connections between the link 310a and each of the link 310b and the connector release tab 306. However, as discussed above, while a specific example of the coupling of the connector release actuator 312a, 312b, and 312c to the connector release tab 306 via the connector release linkage 310a and 310b that allows actuation/movement of the connector release actuators 312a, 312b, and/or 312c to move the connector release actuator 312a, 312b, and 312c, the connector release linkage 310a and 310b, and the connector release tab 306 from a “securing” orientation to a “release” orientation has been described, other connector release linkage configurations and/or other connector release actuator/connector release tab couplings will fall within the scope of the present disclosure as well. One of skill in the art in possession of the present disclosure will appreciate how, with the connector release actuator 312a, 312b, and 312c, the connector release linkage 310a and 310b, and the connector release tab 306 in the “release” orientation, the connector securing feature 308 may move past and “clear” the final securing features on the port 208c to release the connector base 302 from the port 208c (i.e., because the connector base 302 may now be moved out of the port 208c as discussed below).
The method 400 then proceeds to block 408 where the connector on the cable connector system is decoupled from the port on the computing device. With reference to FIGS. 6C and 6D, in an embodiment of block 408, with the connector release actuators 312a, 312b, and/or 312c actuated/moved in the direction E, the user may then move the cable connector system 300 in a direction G such that the connector securing feature 308 clears the final securing features and the initial securing features on the port 208c (as illustrated in FIG. 6C), which allows the user to continue to move the cable connector system 300 in the direction G until the front end 302a of the connector base 302 exits the port 208c (as illustrated in FIG. 6D). As can be seen in FIG. 6E, the user may then release the connector release actuators 312a, 312b, and/or 312c, which allows the biasing member 314 to again bias the connector release actuator system (e.g., the connector release actuator 312a, 312b, and 312c in the illustrated embodiment), the connector release linkage 310a and 310b, and the connector release tab 306 back into the “securing” orientation A illustrated in FIGS. 3A, 3B, and 3C (as well as FIG. 6E), which one of skill in the art in possession of the present disclosure will appreciate allows the cable connector system 300 to subsequently be secured to port as described above with reference to blocks 402 and 404.
Thus, systems and methods have been described that provide for the release of RJ-45 connectors from Ethernet ports via an RJ-45 connector release system that couples an RJ-45 connector release tab on a front end the RJ-45 connector to an RJ-45 connector release actuator located on a rear end of the RJ-45 connector via an RJ-45 connector release linkage. For example, the RJ-45 connector of the present disclosure may include an RJ-45 connector base with a first end that may be inserted in an Ethernet port, and a second end located opposite the RJ-45 connector base from the first end. An RJ-45 connector release tab extends from the RJ-45 connector base adjacent the first end and moves relative to the RJ-45 connector base. An RJ-45 connector securing feature on the RJ-45 connector release tab may engage an Ethernet port to secure the RJ-45 connector base in that Ethernet port. An RJ-45 connector release system includes an RJ-45 connector release linkage coupled to the RJ-45 connector release tab and extending through the RJ-45 connector base, and an RJ-45 connector release actuator adjacent the second end of the RJ-45 connector base and coupled to the RJ-45 connector release linkage. The RJ-45 connector release actuator may be actuated to move, via the RJ-45 connector release linkage, the RJ-45 connector release tab to disengage the RJ-45 connector securing feature from an Ethernet port such that the RJ-45 connector base may be removed from that Ethernet port.
As will be appreciated by one of skill in the art in possession of the present disclosure, the connector release system of the present disclosure provides several benefits over conventional connector systems. For example, the connector release tab of the present disclosure is less likely to break off of the connector due to their actuation via the connector release actuator system of the present disclosure that does not require direct engagement of the user's finger with the connector release tab, thus eliminating the issues discussed above with connecting connectors having broken connector release tabs to ports that typically result in cable replacement and/or support calls Furthermore, the connector release system of the present disclosure provides for easier release of connectors when ports on computing devices are recessed and/or otherwise difficult to access due to the positioning of the connector release actuator system adjacent the rear end of the connector base. Further still, the connector release system of the present disclosure provides ergonomic improvements over conventional connector release systems, reducing hand fatigue in situations where a large number of RJ-45 connectors must be removed from corresponding ports in the same time period (e.g., when switch device(s) are decommissioned). However, while a few specific examples are provided, one of skill in the art in possession of the present disclosure will recognize other benefits of the present disclosure as well.
Although illustrative embodiments have been shown and described, a wide range of modification, change and substitution is contemplated in the foregoing disclosure and in some instances, some features of the embodiments may be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the embodiments disclosed herein.
