[0002] A charging cable is a type of cable used to replenish power to electronic devices. Common types include USB data cables, Lightning data cables, and Type-C data cables. Traditional data cables are usually just simple data cables without any additional functions. As people's needs have increased, existing data cables have LEDs on the charging head. When charging is in progress, the LEDs flash colored lights to indicate that charging is in progress. However, in this way, the LED display is always on. This is not a problem when using it during the day, but when using it at night, it will cause the room lights to flicker, affecting the user's sleep, thus limiting its use.

However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] In the description of the embodiments of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium.

"Fixed" means that the relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of this utility model, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this utility model, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model.

[0016] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0017] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0018] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of the present invention include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] like Figures 1-2 As shown, this utility model provides a touch-emitting charging cable, comprising: a cable body 10, with end housings 11 connected to both ends of the cable body 10, and a metal port 12 at one end of the end housing 11 facing away from the cable body 10. The feature is that a touch panel 13 is provided on the outer side of at least one end of the end housing 11, and an LED light 14 is also provided at the end of the end housing 11 connected to the metal port 12. A sensing chip is also provided inside the end housing 11. The touch panel 13 and the LED light 14 are electrically connected to the sensing chip. When the touch panel 13 is touched, it sends a touch signal to the sensing chip, and the sensing chip controls the LED to operate according to the received signal.

[0020] Furthermore, in this embodiment, the touchpad 13 is made of copper foil or conductive silicone.

[0021] Furthermore, in this embodiment, the outer side of the touch panel 13 is also provided with an insulating coating 15;

[0022] Furthermore, a power management chip is also provided inside the end housing 11, and the power management chip is electrically connected to the LED;

[0023] Furthermore, the sensing chip is also connected to a delay circuit;

[0024] Specifically, to enable the charging cable to alert the user during operation and make it easier for the user to find the plug at night, this application provides a touch panel 13 on the outside of the end housing 11. The touch panel 13 can be embedded in the surface of the end housing 11 or covered on the outside of the end housing 11, and the touch panel 13 exists in the form of an electrode. An LED light 14 is installed at one end of the end housing 11 connected to the metal port 12. The LED light 14 uses RGB LED beads. A sensing chip is also provided inside the end housing 11. The touch panel 13 and the LED light 14 are respectively connected to the sensing chip. The touch sensing adopts a capacitive method, which does not require the application of large physical pressure. The sensing chip uses a touch switch chip. When the user's finger touches the touch panel 13, the touch panel 13 generates a touch signal to the sensing chip. The sensing chip controls the LED light 14 to work according to the received touch signal, so that the LED light 14 lights up, thereby serving as an alert or providing illumination. When the user's finger leaves the touch panel 13, the sensing chip loses the touch signal, and the LED light 14 will turn off, thereby avoiding affecting the user's sleep.

[0025] The touchpad 13 can be made of copper foil or conductive silicone, depending on the usage requirements. In order to prevent accidental power contact, an insulating coating 15, such as UV glue, can be covered on the outside of the touchpad 13 to isolate it, ensure safe use, and prevent damage to the touchpad 13 due to static electricity.

[0026] In the circuit connection, the VCC and GND of the sensing chip are connected to the +5V and GND of the charging cable end. The touch panel 13 is connected to the sensing pin (S pin) of the sensing chip. The output pin (OUT) controls the LED 14 through a resistor / transistor. If the LED 14 is a low-power LED (within 5mA), it can be directly driven by the sensing chip. If a high-brightness LED (>10mA) is required, an NPN transistor is added to amplify the current. In this case, the output of the sensing chip is connected to the base, and the LED 14 + resistor is connected in series in the collector circuit.

[0027] In another embodiment, if it is necessary to delay the LED 14 to turn off according to the usage requirements, an RC delay circuit (10kΩ resistor + 100μF capacitor) can be connected after the OUT pin to achieve the delayed turning off of the LED 14. The delay time can be determined according to the usage requirements.

[0028] In another embodiment, if the brightness of the LED 14 needs to be adjustable, a power management chip (PWM chip) can be added to adjust the brightness. At the same time, the average circuit of the LED 14 can be changed by controlling the duty cycle of the PWM, thereby achieving a gradual change in brightness and producing a breathing light effect. Alternatively, a microcontroller can be used to implement double-click switching of color / mode.

[0029] In summary, by setting a touch panel 13 on the outside of the end housing 11, the LED light 14 can be controlled by touch, so that the charging cable can not only provide charging indication, but also provide illumination in the night environment, without affecting sleep at night. It is low in cost, simple in structure, and greatly improves the user experience of the charging cable.

[0030] This invention is not limited to the description in the specification and embodiments. Therefore, other advantages and modifications can be readily realized by those skilled in the art. Thus, without departing from the spirit and scope of the general concept as defined by the claims and their equivalents, this invention is not limited to the specific details, representative devices and illustrated examples shown and described herein.
