This disclosure relates to accessories for electronic devices and more specifically to multi-configurable electrical cable assemblies adapted to interface with electronic devices.
Electronic devices, such as computers, servers, smart and cellular phones, computing tablets, MP3/audio/video players, gaming devices, laptops, battery and power chargers, and countless others are continuously and rapidly evolving to meet expanding consumer demand. It is not uncommon for such electronic devices to include one or more standardized or proprietary electrical interfaces or connectors for charging or powering the device and/or synchronizing or otherwise facilitating communication with the device.
For example, Universal Serial Bus (USB) is a well-known industry standard that was designed to replace a variety of earlier interfaces, such as serial ports, parallel ports, and power chargers, so as to standardize the communication and power connection of computer peripherals (including keyboards, pointing devices, digital cameras, printers, portable media players, disk drives and network adaptors) to personal computers. There are several formats of USB connectors, for example, Type-A, Type-A SuperSpeed, Type-B, Type-B SuperSpeed, Mini-A, Mini-B, Micro-A, Micro-B, Micro-B SuperSpeed, USB 3.0, USB 3.0 Micro B, USB 3.0 Micro AB, and Type-C. Each of these USB connectors are defined by standardized electrical male (e.g., plugs) and mating female (e.g., receptacles or jacks) connector configurations.
Another example is the Lightning® connector. The Lightning® connector is a proprietary computer bus and power connector created by Apple Inc. to connect Apple's mobile devices such as iPhones, iPads, and iPods to host computers, external monitors, cameras, USB battery chargers, and other peripherals.
A consumer or user of electronic devices often times is faced with the challenge of interfacing electronic devices that have dissimilar electrical interfaces or connectors. Carrying an array of cables with desired interfaces and/or an array of interface adaptors can be expensive and burdensome. Moreover, they can be easily misplaced or otherwise unavailable to the user when needed.
The inventors here have recognized that there is a continuing need, therefore, for a multi-configurable electrical cable assembly capable of facilitating communication with and charging of an electronic device.
Disclosed are numerous aspects of a unique and inventive electrical cable assembly configurable to allow connectivity and/or power between electronic devices having dissimilar electrical interfaces. The cable assemblies generally comprise a cable extending from a first electrical connector to a second electrical connector and a yoke captively and slidably coupled to one end of the cable and rotatably coupled to an adaptor module at the other end. The adaptor module includes one or more electrical connector adaptors that can be selected by the user and aligned to connect to one or more of the electrical connectors on the cable to thereby adapt the cable with a different electrical connection. The configuration, construction, use and manufacture of the component elements and combinations thereof constitute separate aspects of the invention. Accordingly, it should be understood that each of the foregoing and various aspects, together with those set forth in the claims and summarized above and/or otherwise disclosed herein, including the drawings, may be combined to support claims for a device, apparatus, system, method of manufacture, and/or use without limitation.
These and other features, aspects and advantages are described below with reference to the drawings, which are intended to illustrate, but not to limit, the invention. In the drawings, like reference characters denote corresponding features consistently throughout similar embodiments.
Each drawing is generally to scale and hence relative dimensions of the various components can be determined from the drawings.
As summarized above and illustrated in the drawings, disclosed herein are various aspects of a protective case for a mobile device. Many of those aspects are summarized above and illustrated in the drawings.
As set forth above, disclosed in
The cable 10 extends from a first end 110 to a second end 120. The first end 110 terminates at a first electrical connector 112 and the second end 120 terminates at a second electrical connector 122. In the implementation illustrated, the first electrical connector 112 is USB Type A male connector and the second electrical connector 122 is a USB micro male connector. The first and second electrical connectors 112, 122 are housed within respective overmold housings 114, 124 that serve to protect and secure the electrical connectors to the cable 10. The first and second electrical connectors 112 and 122 are coupled to one another through one or more conductive pathways 140 (not shown) in the cable 10 that are housed and protected within an external cable jacket 130.
The slidable yoke or sleeve 200 extends from a first end portion 210 to a second end portion 220. The first end portion 210 is comprised of a sleeve that is captively coupled to the cable jacket 130 and dimensioned to slide over the cable jacket 130. The overmold housings 114, 124 are dimensioned to serve as a slide-stop to the yoke 200 on either end of the cable 10. In one implementation the yoke is configured to be detachably coupled to the cable 10. In such an implementation, the sleeve may be configured to only partially encircle the cable jacket 130 and thereby allow insertion and removal of the cable 10 therefrom. The second end portion 220 of the yoke 200 includes a first support structure 221 and a second support structure 222 spaced apart and opposed to one another. Each of the first and second support structures 221, 222 are in the shape of a support arm and include opposed attachment pins 223 and 224 (best illustrated in
The first electrical connector adaptor 300 includes a housing 305 extending from a first adaptor end 310 to a second adaptor end 320. The first adaptor end 310 includes a third electrical connector 311 and the second adaptor end 320 includes a fourth electrical connector 321. In the illustrated implementation, the first electrical connector adaptor 300 is configured to convert a USB micro connection to a Lightning connection. The third electrical connector 311 is a male lightning connector and the fourth electrical connector 321 is a female USB micro connector adapted to connect to the second electrical connector 122 (which is a male USB micro connector) at the second end 120 of the cable 100. The fourth electrical connector 321 is electrically connected to the third electrical connector 311 via electrical pathways provided within the adaptor housing 305. Thus, when the fourth electrical connector 321 is connected to the second electrical connector 122, the third electrical connector 311 is electrically connected to the first electrical connector 112 at the first end 110 of the cable 100. Pivot point apertures 323, 324 are provided on opposing sides of the first electrical connector adaptor 300 to facilitate independent and direct connection to the corresponding attachment pins 223 and 224 on the yoke 200. Interlocking slide connections 340 located at the mid-region 330 of the housing 305 (best illustrated in
The second electrical connector adaptor 400 is similar to the first electrical connector adaptor 300, and includes a housing 405 extending from a third adaptor end 410 to a fourth adaptor end 420. The third adaptor end 410 includes a fifth electrical connector 411 and the second adaptor 420 end includes a sixth electrical connector 421. In the illustrated implementation, the second electrical connector adaptor 400 is configured to convert a USB micro connection to a USB Type C connection. The fifth electrical connector 411 is a male USB Type C connector and the sixth electrical connector 421, like the fourth electrical connector 321, is a female USB micro connector adapted to connect to the second electrical connector 122 at the second end 120 of the cable 100. The sixth electrical connector 421 is electrically connected to the fifth electrical connector 411 via electrical pathways provided within the adaptor housing 405. Thus, when the sixth electrical connector 421 is connected to the second electrical connector 122, the fifth electrical connector 411 is electrically connected to the first electrical connector 112 at the first end 110 of the cable 100. Pivot point apertures 423, 424 are provided on opposing sides of the second electrical connector adaptor 400 to facilitate independent and direct connection to the corresponding attachment pins 223 and 224 on the yoke 200. Interlocking slide connections 440 located at the mid-region 430 of the housing 405 (best illustrated in
The adaptor module 500 is comprised of one or more electrical connector adaptors 300, 400. In
Alternatively, the attachment pins 223 and 224 may be inserted or plugged into opposing pivot point apertures 323, 324 or 423, 424 on opposing sides of the 1st or 2nd electrical connector adaptor 300, 400. In this regard, it should be understood that the electrical connector adaptors 300 and 400 may be disengaged or de-coupled from one another by disengaging the interlocking slide connections 340 from 440 and the yoke 200 may be rotatably coupled to a single connector adaptor 300 or 400 as illustrated in
As illustrated in the drawings, in operation, the yoke 200 is configured to be extended and retracted from the cable 100 to facilitate operation of the cable assembly 10. The sleeve of the yoke 200 slides along and is guided by the cable jacket 130 as it is moved from one position to another. When the yoke 200 is extended in an unconnected positions, such as that illustrated in
It should be understood that while certain types of electrical connectors (such as USB Type A, USB micro, USB Type C, and Lightning) are illustrated and described herein, any standard, proprietary, or custom computer bus and/or power connector may be used. Moreover, it should be understood that while the first and second electrical cable connectors 112, 122 are in the illustrated implementation are different male connectors, it should be understood that they could be of the same type and/or one of the connectors could be female and the other male (or female/female). Furthermore, it should be understood that while the adaptor module 500 may comprise any number of electrical connector adaptors 300, 400, etc., including one, two, three, four, five, six etc. It should also be understood that the cable assembly 10 disclosed herein can be part of a cable assembly adaptor system that includes additional electrical connector adaptors, adaptor modules, and/or multiple yokes that can be coupled together as described herein to allow a user to customize their cable assembly 10 solution to meet the user's particular needs.
It should also be understood that in some embodiments each end 110, 120 of the cable assembly may be configured to connect to separate slidable yokes 200, 200* (not shown) and electrical connector adaptors 300, 400 or adaptor modules 500. In this way, a user could carry a single cable with multiple adaptors to accomplish all potential connections. For example, the cable 100 may include a male USB type-C first end 110 and a male USB type-C second end 120. A first yoke 200 configured to connect to first end 110 may include a first adaptor module 500 including both a first electrical connector adaptor 300 including a male Lightning first adaptor end 310 and a female USB type-C second adaptor end 320 and a second electrical connector adaptor 400 including a male USB micro first adaptor end 410 and a female USB type-C second adaptor end 420. A second yoke 200* configured to connect to second end 120 may include only a single electrical connector adaptor 300* including a male USB micro first adaptor end 310* and a female USB type-C second adaptor end 320*.
In some embodiments, the yoke 200 and/or the electrical connector adaptors 300, 400 used with a first end 110 may be configured to also fit over and pair with the second end 120. In other embodiments, the yoke 200 and/or the electrical connector adaptors 300, 400 (or adaptor module 500) configured for use with a first end 110 may be constructed or dimensioned differently from the yoke 200* and/or the electrical connector adaptors 300*, 400* (or adaptor module 500*) configured for use with the second end 120 to ensure that users only use an electrical connector adaptor 300 with the appropriate end 110, 120. One method to ensure users do not incorrectly attach the wrong yoke 200, 200* to the wrong end 110, 120 would be to include a thicker cable jacket 130 near a first end 110 and a thinner cable jacket 130 near a second end 120 (or vice versa). Yokes 200 and 200* could be molded with first end portions 210 that pair to only a first end 110 or second end 120. Alternatively, ensuring users connect the electrical connector adaptor 300 to the correct end 110, 120 may be implemented by molding first electrical connector overmold 114 and second electrical connector overmold housing 124 with different shapes, dimensions, or connectors and molding the housings 305, 405 (configured to pair with first electrical connector overmold housing 114) to be different from housings 305*, 405* (configured to pair with second electrical connector overmold housing 124).
In an alternate embodiment, the three-in-one charge/sync cable assembly 10 may include a Y-fork in the cable 100, including the first end as described in previous embodiments, but also including second end 120 including a second electrical connector 122 as well as a third end (not shown) including a third electrical connector (not shown). This sort of Y-embodiment of the three-in-one charge/sync cable 10 may be used as both a connector and a hub, configured to provide power to or communicate data to and from multiple peripherals simultaneously. In this embodiment, the connection point where the three cables 100 meet may include reinforced conductive pathways 140 and reinforced cable jacket 130 to withstand potential rough use. Additional electronic components may be incorporated in the cable assembly 10 to ensure both peripherals are recognized and powered by the master device connected to first end 110.
In some embodiments, cable 100 may include female first electrical connector 110 and female second electrical connector 122. In these or some other embodiments, the electrical connector adaptors 300, 400 may include a male second adaptor end 320, enabling the male second adaptor ends 320 to connect to a female electrical connector 112, 122. In some embodiments, the electrical connector adaptors 300, 400 may include a female first adaptor end 310 and a female second adaptor end 320, enabling the cable to be used as an extension cable or for use with devices including built-in male end plugs. In other embodiments, the electrical connector adaptor 300 may include additional circuitry capable of converting data signals (e.g., an electrical connector adaptor incorporating a SATA III to USB 3.0 bridge between a female USB 3.0 second adaptor end 320 and a male SATA first adaptor end).
Additionally it is noted that the power and data throughput of various standards has increased over time. In some embodiments, the three-in-one charge/sync cable assembly 10 includes conductive pathways 140 optimized for the power and data throughput levels of the highest configurable electrical connector 300 enabled by the cable. In this way, the three-in-one charge/sync cable assembly 10 is backward compatible without sacrificing top-end performance.
It should also be understood that the cable jacket 130, yoke 200, overmold housings 114, 124, or connector housings 305, 405 may be formed of any suitable material, such as a molded thermoplastic elastomer or thermoplastic rubber and/or nylon or other durable polymer. The yoke 200, for example, may be formed as a unitary molded Nylon structure to facilitate snapping on and off the sleeve from the cable jacket 130.
The cable assembly 10 herein described may be readily configured and employed, for example, as a 3-in-1 charging or sync cable. When configured in a USB Type A to USB micro configuration, the USB Type A plug 112 can be used to plug into a USB receptacle of a power source, e.g., a power adaptor plugged into a wall socket, a power bank, or a desktop computer, while the USB micro plug 122 may be used to plug into, for example, a smart phone or camera to facilitate charging or data synchronization. Similarly, when configured in USB Type A to USB Type C configuration (such as that illustrated in
