DETAILED DESCRIPTION

The present disclosure is described more fully hereinafter with reference to the accompanying drawings, in which various aspects of a compact and portable USB cable assembly including a carabiner clip are shown. This disclosure, however, may be embodied in many different forms and should not be construed as limited by the various aspects of the USB cable assembly presented herein. The detailed description of the USB cable assembly is provided below so that this disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

The detailed description may include specific details for illustrating various aspects of a USB cable assembly. However, it will be apparent to those skilled in the art that the disclosure may be practiced without these specific details. In some instances, well known elements may be shown in block diagram form, or omitted, to avoid obscuring the inventive concepts presented throughout this disclosure.

By way of example, various aspects of a USB cable assembly may be illustrated by describing components that are coupled, attached or connected together. However, the disclosure, while described in terms of a USB cable assembly, may be practiced with other cable and connector standards and formats. As used herein, the terms “coupled”, “attached”, and “connected” may be used to indicate either a direct connection between two components or, where appropriate, an indirect connection to one another through intervening or intermediate components. In contrast, when a component is referred to as being “directly coupled”, “directly attached” or “directly connected” to another component, there are no intervening elements present.

Relative terms such as “lower” or “bottom” and “upper” or “top” may be used herein to describe one element's relationship to another element illustrated in the drawings. It will be understood that relative terms are intended to encompass different orientations of a USB cable assembly in addition to the orientation depicted in the drawings. By way of example, if a USB cable assembly in the drawings is turned over, elements described as being on the “bottom” side of the other elements would then be oriented on the “top” side of the other elements. The term “bottom” can therefore encompass both an orientation of “bottom” and “top” depending on the particular orientation of the apparatus.

Various aspects of a USB cable assembly may be illustrated with reference to one or more exemplary embodiments. As used herein, the term “exemplary” means “serving as an example, instance, or illustration,” and should not necessarily be construed as preferred or advantageous over other embodiments of a USB cable assembly disclosed herein.

The USB cable assembly is compact and portable so that it can easily be stowed for transport, greatly enhancing a consumer's ability to use the USB cable assembly to recharge, power, and/or perform data transfer/synchronization for one or more portable electronic devices (PEDs) that rely on a USB port for power, recharging and/or data transfer. The USB cable assembly may be configured to provide one or more USB 5V connectors for connecting to one or more PEDs when plugged into a host device, which may be a personal computer, for example.

FIG. 1 provides a perspective view of a USB cable assembly 10 in accordance with aspects of the present disclosure. The USB cable assembly 10 is configured to connect a PED to a host device, such as a computer, for example. A USB cable 100 connects an upstream connector 300, which is preferably a male 4 pin Type A USB connector, to a downstream connector 400, which may be a 30 pin connector, for example, of the type typically used as a dock connector for an iPOD® or iPhone®, via a main body section 200. The USB cable 100 may be a shielded cable having two wires, a power and a ground wire, for delivering power at 5 volts from the host to the PED, and a braided pair of wires for carrying data between the host and the PED.

In accordance with another aspect of the present disclosure, the USB cable assembly 10 may be provided with a suitable attachment mechanism, such as carabiner clip, as shown in FIGS. 1-4, that completes a through-hole 510 formed in the main body section 200. The carabiner clip includes a hinged spring-loaded arm 500 that swings inwardly into the through-hole 510 to enable easy (e.g., one-handed) attachment, for example, to a belt loop, or a ring, such as on a backpack. In this manner, and due to its compact, lightweight and ergonomic design, the USB cable assembly 10 may be easily stored and/or transported for convenient access and efficient use.

As depicted in FIG. 1, the USB cable assembly 10 is in an operational configuration and includes the main body section 200, a detachable upstream connector body section 310 coupled to the upstream connector 300, and a detachable downstream connector body section 410 coupled to the downstream connector 400. The main body section 200 includes an upstream connector port 230 (see also FIG. 2) and a downstream connector port 240 for slidably receiving the upstream and downstream connectors, 300 and 400, respectively. In the operational configuration, the upstream and downstream connectors, 300 and 400, are disengaged from the respective upstream and downstream connector ports 230 and 240, respectively, so that the upstream connector body section 310 and the downstream connector body section 410 may be separated from the main body section 200. The upstream connector body section 310 and the downstream connector body section 410 remain connected to the main body section 200 by way of the USB cable 100. Thus, in the operational configuration, the upstream connector 300 is available for attachment to a Type A USB connector port, for example, on the host device, and the downstream connector 400 is available for attachment to the PED.

As shown in FIG. 4, when the USB cable assembly 10 is in a storage configuration, the upstream and downstream connectors, 300 and 400 are secured in the upstream and downstream connector ports, 230 and 240, respectively. The upstream connector body section 310 and the downstream connector body section 410 mate with the main body section 200 to form a unified body that may be generally flat, with smooth front and rear surfaces, and rounded corners and edges. The upstream connector body section 310 may be formed with rounded peripheral edges that align with the rounded peripheral edges of the main body section 200 when the upstream connector 300 is placed in a stored position, i.e., when fully inserted into the upstream connector port 230. The smooth, rounded contours of the USB cable assembly 10 allow a user to store the assembly 10 in garment pockets, for example, without snagging and tearing. Additionally, as shown in FIG. 2, the hinged spring-loaded arm 500 of the carabiner clip may be pressed inwardly toward the through-hole 510 for easy attachment to a loop on a garment, backpack, computer bag, or the like.

As shown in FIGS. 1-4, the main body section 200 may be formed with an outer casing made of nonconductive material. The outer casing may be formed from a combination of two molded shells, for example, or any other method of forming a protected enclosure for securing and protecting the upstream connector 300, the downstream connector 400, and the USB cable 100 connecting the upstream connector 300 to the downstream connector 400. The main body section 200 may be generally hollow, for example, and formed with various features for providing structural support and positional guidance, for example, of the USB cable 100.

When in the stored position, the upstream connector body section 310 mates with the main body section 200 in a position offset to one side of a longitudinal centerline (not shown) of the USB cable assembly 10. As shown in FIGS. 1 and 2, an upstream cable passage 32 formed in a corner peripheral surface of the upstream connector body section 310 aligns with a main body channel 130 that cradles an upstream portion of the USB cable 100 leading to the upstream connector 300 to cradle the upstream portion of the USB cable 100 along a periphery of the main body section 200. The upstream portion of the USB cable 100 enters the outer casing of the upstream connector body section 310 through the upstream cable passage 32 and is connected to the upstream connector 300. The upstream connector 300 is fixedly attached to the upstream connector body section 310 so that the upstream connector body section 310 houses and protects the USB cable 100 connection to the upstream connector 300.

As shown in FIGS. 1-6 and 8, the downstream connector body section 410 may be formed as a half-disc, for example, with an outer casing having a rounded semicircular edge 41 and a mating surface 42. The downstream portion of the USB cable 100 enters the outer casing of the downstream connector body section 410 through a downstream passage 43 and is connected to the downstream connector 400. A downstream body channel 45 (as shown in FIGS. 2, 5 and 8) may be formed in the semicircular edge 41 along a peripheral arc from where the USB cable 100 enters the downstream connector body section 410, at the downstream passage 43, to a lateral edge of the mating surface 42.

When the downstream connector 400 is placed in the stored position, as shown in FIG. 4, i.e., when fully inserted into the downstream connector port 240, the mating surface 42 of the main body section 200 abuts an end surface 29 of the downstream connector body section 410. As shown in FIG. 5, a cable passage 142 may be formed in a peripheral surface of the main body section 200. The cable passage 142 aligns with the downstream body channel 45 to cradle the downstream portion of the USB cable 100 along a periphery of the downstream connector body section 410. The downstream connector 400 is fixedly attached to the downstream connector body section 410 so that the downstream connector body section 410 houses and protects the USB cable 100 connection to the downstream connector 400.

In use, the USB cable assembly 10, which may be secured to a keychain, belt loop or backpack ring, via the hinged spring-loaded arm 500 of the carabiner clip and through-hole 510, for example, is placed into the operational configuration by slidably removing the upstream and downstream connectors, 300 and 400, from the upstream and downstream connection ports 230 and 240, respectively. The unitary design of the cable assembly 10 ensures that the USB cable 100 remains slidably secured to the main body section 200 when the upstream and downstream connector body sections 310 and 410 are respectively disengaged. In this manner, all components of the cable assembly 10 remain continuously attached at all times, whether or not the cable assembly 10 is being used in an operational or storage configuration. Thus, a user will not misplace or lose a protective cap, for example, and can be assured that the critical components of the cable assembly 10 may always be stored in an efficient, protective manner, preventing damage and extending the effective life of the cable assembly 10 indefinitely. Furthermore, the user is able to securely store the cable assembly 10 in an accessible storage location and have the ability to remove the cable assembly 10 from its stored location for use.

In accordance with another aspect of the present disclosure, with the cable assembly 10 in an operational configuration, a distance that the upstream and downstream connectors, 300 and 400, can respectively extend away from the main body section 200 may be adjusted. For example, when initially disengaged from the main body section 200, the upstream connector body section 310 and the downstream connector body section 410 extend a predetermined distance from the main body section 200. Because the USB cable 100 is not fixed to the main body section 200, but slidably passes through the main body section 200, pulling on either of the upstream connector body section 310 or the downstream connector body section 410 will extend the respective body section 310 or 410 a distance from the main body section 200. The other of the upstream connector body section 310 or the downstream connector body section 410 will simultaneously retract the same distance toward the main body section 200 as the USB cable 100 is pulled through the main body section 200. The length that either of the upstream connector body section 310 or the downstream connector body section 410 can extend is limited only by the predetermined distance that the other of the upstream connector body section 310 or the downstream connector body section 410 initially extends from the main body section 200 upon disengagement from a stored configuration.

Once the cable assemble 10 is opened and configured as desired by the user, the upstream connector 300 may be connected to an appropriate port on the host device, and the downstream connector 400 connected to an appropriate port on the PED. The host may thus supply a predetermined current or power to the PED at 5V while simultaneously exchanging data with the PED in accordance with a specified USB standard, which may be USB 2.0 or USB 3.0, for example.

The USB cable assembly 10 may be placed in a storage configuration by inserting the upstream connector 300 into the upstream connector port 230 so that the upstream connector body section 310 seats flush with the main body section 200. The downstream connector 400 is inserted into the downstream connector port 240 so that the downstream connector body section 410 seats flush with the main body section 200. As shown in FIG. 2, when in the storage position, the upstream and downstream connectors, 300 and 400, occupy an upper and a lower space inside the main body section 200 and are separated substantially by a thickness of the USB cable 100. The upstream portion of the USB cable 100 may be pulled taut and secured into the main body channel 130, and the downstream portion of the USB cable 100 may be pulled taut and secured into the downstream body channel 45. The channels 130 and 45 effectively shield and protect the USB cable 100 from damage by preventing exposure to direct impacts and snags, for example. Due to the compact and efficient configuration of the USB cable assembly 10, as described above, the assembly is able to be lightweight, ergonomic and cost-efficient to manufacture while providing substantial protection to the critical components of the assembly, and being easily stored on and retrieved from a convenient hook or loop by operation of the carabiner hinged spring-loaded arm 500.

FIGS. 9-19 show another variation of a USB cable assembly 900, in accordance with aspects of the present disclosure, in which the USB cable assembly 900 may be provided with multiple downstream connectors, such as dual mini and micro USB connectors. As show in FIGS. 9-19, the USB cable assembly 900 shares similar aspects with respect to the upstream side of the USB cable assembly 10, including a Type-A upstream connector 800, an upstream connector body section 530 and a main body section 520 provided with an upstream connector port 730 for receiving the upstream connector 800, and a hinged spring-loaded arm 500 of the carabiner claim and through-hole 510.

The downstream side of the USB cable assembly 900, as depicted in FIGS. 9-10, has a first downstream connector 940, which may be a mini-A or mini-B type USB connector, and a second downstream connector 950, which may be a micro-A or micro-B type USB connector. The first and second downstream connectors, 940 and 950, may secure to and extend from a housing 910 via a cable 600. The housing 910 may be formed with a first main body insertion step 912 and a second main body insertion step 962. To place the USB cable assembly 900 into a storage configuration, the first housing 910 is slidably received into the main body section 520. First and second main body insertion steps, 912 and 962, present a unified, lateral insertion step that is contoured in order to be press fit, for example, into a main body downstream port 525, of the main body section 520.

The main body section 520 has an interior chamber (not shown) for storing and protecting the cable 600, when the USB cable assembly 900 is placed into a storage configuration. As shown in FIGS. 9 and 10, the USB cables 600 extends from the housing 910. The cables 600 extends from the housing 910 toward the main body downstream port 525. As shown in FIGS. 11-19, when the USB cable assembly 900 is placed into the storage configuration, the cables 600 is entirely contained in the interior chamber of the main body section 520.

The unitary design of the cable assembly 900 ensures that the USB cable 600 remains secured to the main body section 520 when the upstream connector 800 and both downstream connectors 940 and 950 are respectively disengaged. In this manner, all components of the cable assembly 900 remain continuously attached at all times, whether or not the cable assembly 900 is being used in an operational or storage configuration. Thus, a user will not misplace or lose a protective cap, for example, and can be assured that the critical components of the cable assembly 900 may always be stored in an efficient, protective manner, preventing damage and extending the effective life of the cable assembly 500 indefinitely. Furthermore, the carabiner hinged spring-loaded arm 500 and the through-hole 510 enable the user to easily store and retrieve the cable assembly 900.
