Technical Field
The present invention relates to a power and/or data cable for an electronic device. More particularly, the present invention relates to a power and/or data cable for an electronic device having an illuminated universal serial bus type-C (USB-C) interconnect interface.
Background
Electronic devices, in particular portable electronic devices such as mobile phones, portable computers and/or tablet computers, utilize cables for charging and/or data exchange.
Electronic devices may need to be interconnected with a cable, for example as part of daily life, charging often being performed, for example, at the user's bedside so that the device can be recharged at night while still being available for use even while charging.
One problem with existing cables is that it can be difficult to interconnect a male cable connector interface to a female interface of an electronic device because the interfaces are small and require relatively precise alignment prior to interconnection. Alignment for interconnection in poor lighting conditions and/or darkness is particularly difficult because the female interface of the electronic device may be an embedded socket that prevents alignment by touch.
Illumination cables are known in which the cable illuminates to indicate the energized state. But a continuously illuminated cable may waste power and/or cause undesirable lighting, for example in places/times where darkness may be preferred, such as a bedroom when another person is sleeping.
Application publication US2014/0140076 to Morrow et al discloses a lighting interface cable having a switch activated Light Emitting Diode (LED) configured to illuminate a connection interface area when a switch disposed on a connector body is activated. The LED is powered via the Vbus conductor of the USB2.0 connection interface. According to the USB2.0 specification, the Vbus conductor is always in a powered state.
The USB-C interface is an emerging industry standard for the interface/interconnection of many electronic devices. The USB-C interface provides both power and data interconnection in a very small space, which reduces the required mating connector size of the electronic device, thereby making the electronic device smaller and therefore more portable. Unlike previous USB connection interface standards, the USB-C interface is reversible and is capable of transferring device-specific power levels. For example, a connected electronic device may specify a high power level to enable a fast charging protocol.
To ensure that an electronic device coupled to the charger via the USB-C is not provided with a power level above that at which it is configured, the USB-C interface provides data lines for negotiating the appropriate power level between the power supply (smart charger) and the electronic device before the Vbus conductor is powered on.
Convenience, cost, and/or reliability may be important factors in commercial success in the consumer electronics market.
It is therefore an object of the present invention to provide a cable which overcomes the drawbacks of the prior art.

Detailed Description
The inventors have realized that cables with USB-C connection interfaces cannot power interconnect area illumination LEDs with previously relied on Vbus wires to guide the interconnect in dark environments, because the USB-C connection interface provides for: neither Vbus conductor is powered up until the connection interfaces have been interconnected and the data negotiation to identify the proper power level of the connected electronic device has been completed over the interconnect. That is, according to the USB-C specification, the Vbus conductors are not powered until after the desired illuminated interconnect operation has completed, so conventional illumination connection interfaces cannot operate when the connection interface is USB-C.
Details of the USB-C specification "universal serial bus revision 3.2" may be found via the USB implementers forum (www.USB.org) of bifenthion, oregon, which is incorporated herein by reference in its entirety.

As shown in fig. 2, the USB-C connection interface includes up to 24 pins (12 pins per side), including CC (configuration channel) pins (CC1 on the first side and CC2 on the second side). The CC pin is used by the USB-C connection interface for direction determination, negotiation of the power level to be transmitted on Vbus, and/or identification of the audio mode (representing that the headset is attached-independent of the power transmission mode). Via the CC pin, the power adapter and the electronic device interconnected via the USB-
According to the USB-C power transmission specification, the CC1 pin and the CC2 pin of a USB-C power adapter are internally connected to 3.3V or 5V via pull-up resistors. An exemplary connection of the interior of the

The mechanical switch 15 is preferred over a capacitive switch because a capacitive switch may be activated whenever a surface of the capacitive switch is touched or when a surface of the capacitive switch is touched to another surface having suitable capacitive characteristics; and/or may not reliably actuate the capacitive switch when the user does not have the proper body capacitance (e.g., due to an insulating coating that preferentially inhibits charging and/or discharges any charge that may be present, the environment of the ground, and/or humidity). In the case of applying a capacitive switch to an interface cable as an operator of a lamp or the like, the capacitive switch may accidentally actuate if accidentally moved into contact with a suitable surface, thereby turning on the lamp and disturbing nearby people.
As referred to herein, a mechanical switch is defined as a switch that requires physical movement of at least a portion of the switch to ensure or break electrical continuity across the switch.

It will be appreciated by those skilled in the art that the lighting interface cable remains operable in accordance with the USB-C specification, and further provides a positive engagement feature for activating lighting that is less likely to be inadvertently activated by merely accidentally contacting surrounding objects. Furthermore, the circuit requirements for the lighting interface cable enable the lighting function to be increased with minimal additional cost and high reliability.
