FIELD OF THE DISCLOSURE

The present disclosure generally relates to information handling systems, and more particularly relates to a toolless direct current connector with ground.


BACKGROUND

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, or communicates information or data for business, personal, or other purposes. Technology and information handling needs and requirements can vary between different applications. Thus, information handling systems can 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 can be processed, stored, or communicated. The variations in information handling systems allow 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 can include a variety of hardware and software resources that can be configured to process, store, and communicate information and can include one or more computer systems, graphics interface systems, data storage systems, networking systems, and mobile communication systems. Information handling systems can also implement various virtualized architectures. Data and voice communications among information handling systems may be via networks that are wired, wireless, or some combination.

Referring now to FIG. 3, information handling system 300 further includes a power supply 304. Toolless DC power connector 302 includes a plug 310, a removable sliding cover 312, a toolless component 314, latches 316, and a frame 318. Power supply unit 304 includes a power supply receptacle 320 and a control board 321. Power supply receptable 320 includes a frame 322, catches 324, a return pin 325, a power pin 326, and a ground pin 327. Plug 310 includes a ground terminal 330, a return terminal 332, and a power terminal 334. Toolless component 314 includes a tab 340. DC power connector 302 may include additional components without varying from the scope of this disclosure.

In certain examples, plug 310 may be configured or built so that ground terminal 330 may connect with power supply receptacle 320 before return terminal 332 or power terminal 334. For example, electrical connections within ground terminal 330 may extend further from frame 318 as compared to electrical connections within both return terminal 332 and power terminal 334. Additionally or alternatively, ground pin 327 may extend further from frame 322 as compared to return pin 325 and power pin 326. In these examples, the electrical connection of ground terminal 330 may be the last connection disconnected from power supply receptacle 320, such as from ground pin 327, as toolless DC power connector 302 is removed from a power supply unit. Plug 310 may provide necessary safety features of ground terminal 330 being the first terminal connected to power supply receptacle 320 and the last terminal disconnected from the power supply receptacle.


In certain examples, toolless component 314 may be physically coupled to latches 316, such that the toolless component may control movement of the latches. In an example, latches 316 may be biased in a locked position, and a force exerted on the latches via toolless component 314 may cause the latches to transition from the locked position to an unlocked position. In response to a force being exerted on DC power connector 302 in the direction of arrow A, plug 310 may be inserted within frame 322 of power supply receptacle 320. As plug 310 is inserted within power supply receptacle 320, latches 316 may flex away from the locked position toward the unlocked position. When plug 310 is fully inserted within power supply receptacle 320, hook portions of latches 316 may snap fit within catches 324 of the power supply receptacle as shown in FIG. 4.


Referring now to FIG. 4, hook portions of latches 316 are located within catches 324 to securely hold DC power connector 302 in both physical and electrical communication with power supply receptacle 320. In this example, power from DC power connector 302 may be provided to control board 321 via power supply receptacle 320. In an example, an individual may exert a force on tab 340 of toolless component 314 in the direction of arrow B. Based on the force on tab 340, toolless component 314 may exert a substantially equal force on latches 316. In an example, the force exerted on latches 316 that may cause the latches to transition from the locked position to the unlocked position.

For example, screws, such as screws 754 in FIG. 7, may be secure return wire 522 to return connector 502. Similarly, screws, such as screws 752 in FIG. 7, may be secure power wire 524 to return connector 504. A screw, such as screw 750 in FIG. 7, may be secure ground wire 526 to return connector 506.


In an example, removable sliding cover 312 may be inserted within notches of fame 318 which in turn may place the removable sliding cover between ground connector 506 and both of return connector 502 and power connector 504. In this example, removable sliding cover 312 may prevent an individual from touching the return connector 502 and/or power connector 504 while handling toolless DC power connector 302. In certain examples, removable sliding cover 312 may be inserted within frame 318 after return wire 522 is connected to return connector 502 and power wire 524 is connected to power connector 504. Removable sliding cover 312 may prevent electrocution of the individual that may result if the individual accidentally touches ground connector 506 and one of return or power connector 502 and 504 at the same time.


In certain examples, tabs 512 and 514 may be utilized by an individual to exert a force on removable sliding cover 312. For example, an individual may exert a force on tabs 512 and 514 to slide removable sliding cover 514 along notches of frame 318 until the removable sliding cover is fully inserted within the frame. In certain examples, main portion 510 may be any suitable shape to separate ground wire 526 from both return wire 522 and power wire 524.

In certain examples, plug 710 may be configured or built so that ground terminal 730 may connect with power supply receptacle 802 of FIG. 8 before return terminal 732 or power terminal 734. For example, electrical connections within ground terminal 730 may extend further from frame 716 as compared to electrical connections within both return terminal 732 and power terminal 734. In this example, the electrical connection of ground terminal 730 may be the last connection disconnected from power supply receptacle 802 as toolless DC power connector 702 is removed from a power supply unit. Plug 710 may provide necessary safety features of ground terminal 730 being the first terminal connected to power supply receptacle 802 and the last terminal disconnected from the power supply receptacle.


In certain examples, latches 714 may be physical connected to plug 710.

When plug 710 is fully inserted within power supply receptacle 802, hook portions of latches 714 may snap fit within catches 812 of the power supply receptacle as shown in FIG. 8.


Referring now to FIG. 8, hook portions of latches 714 are located within catches 812 to securely hold DC power connector 702 in both physical and electrical communication with power supply receptacle 802. In this example, power from DC power connector 702 may be provided to control board 804 via power supply receptacle 802. In an example, an individual may exert a force on toolless component 712 in the direction of power supply receptacle 802. Based on the force on toolless component 712, the toolless component may exert a substantially equal force on catches 812. In an example, the force exerted on catches 812 that may cause the catches to transition from the locked position to an unlocked position.


When catches 812 are in the unlocked position, toolless DC power connector 702 may be removed from within frame 810 of power supply receptacle 802. For example, plug 710, illustrated in FIG. 7, may disconnect from electrical components within frame 810. As stated above, ground terminal 730, illustrated in FIG. 3, may be the last terminal of DC power connector 702 to be disconnected from corresponding terminals of power supply receptable 802.
