It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0039] It should be noted that the terms "first" and "second" in the description and claims of the present utility model are used to distinguish different objects rather than to describe a specific order.

[0044] Please combine Figure 1 and Figure 2 The first embodiment of the utility model provides a connection terminal 10, including a circuit board 1, on which a light-emitting circuit 2, a photosensitive circuit 3 and a control circuit 4 are provided; the control circuit 4 adjusts the working brightness of the light-emitting circuit 2 accordingly based on the photosensitive signal received from the photosensitive circuit 3, so that the working brightness of the light-emitting circuit 2 is positively correlated with the brightness of the external environment.

[0045] It can be understood that the connection terminal 10 provided in the embodiment of the present invention can automatically adjust the light brightness when a change in the ambient light intensity is detected through the cooperation of the light-emitting circuit 2, the photosensitive circuit 3 and the control circuit 4. Therefore, in a high-brightness environment, the brightness of the light-emitting circuit 2 increases so that the user can clearly see the working status of the data line 100 connection terminal 10, and in a low-brightness environment, the brightness of the light-emitting circuit 2 decreases to avoid the light being too glaring. Specifically, the function of detecting the intensity of the external ambient light is realized by the photosensitive circuit 3, and the control circuit 4 automatically adjusts the brightness of the light-emitting circuit 2 according to the detection result of the photosensitive circuit 3. When the brightness of the external environment is high, the light-emitting brightness of the light-emitting circuit 2 is high, and when the brightness of the external environment is low, the light-emitting brightness of the light-emitting circuit 2 is low.

[0046] Please continue reading Figure 2As a feasible implementation manner, the connection terminal 10 further includes an external connection port 6 , which is provided at one end of the circuit board 1 and electrically connected to the circuit board 1 .

[0047] It should be noted that the connection terminal 10 can be an input terminal or an output terminal; correspondingly, the external port 6 can be an input port or an output port.

[0048] It is understandable that when the connection terminal 10 is an input terminal, the corresponding external port 6 is an input port. In this case, the input port is used to connect an external power source to the circuit board 1, that is, to power the light-emitting circuit 2, the photosensitive circuit 3, and the control circuit 4 on the circuit board 1. At the same time, the circuit board 1 is also provided with an output welding port for electrically connecting to an external wire 20. Correspondingly, when the connection terminal 10 is an output terminal, the external port is an output port, and the circuit board 1 is provided with an input welding port. In this case, the circuit board 1 is connected to a power source through the input welding port, powering the light-emitting circuit 2, the photosensitive circuit 3, and the control circuit 4 on the circuit board 1, and powering external devices through the output port.

[0049] Optionally, the connection terminal 10 includes at least one of Type-C, Lightning, and USB. Generally speaking, when the connection terminal 10 is an input terminal, generally only one type of interface is set. When the connection terminal 10 is an output terminal, one or more types of interfaces can be selected.

[0050] See also Figure 3 As a feasible implementation manner, the photosensitive circuit 3 includes a photoresistor R3 , and the photoresistor and the light-emitting circuit 2 are located on the same surface of the circuit board 1 .

[0051] It can be understood that in the embodiment of the present invention, the detection accuracy of the photosensitive circuit 3 is high, which can ensure that the brightness adjustment of the light-emitting circuit 2 is more accurate; specifically, this embodiment ensures that the light-emitting circuit 2 and the photosensitive circuit 3 are in the same external lighting environment by arranging the photoresistor and the light-emitting circuit 2 on the same side of the circuit board 1, thereby avoiding detection errors caused by different positions.

[0052] As a feasible implementation, the photoresistor R3 is a chip photoresistor R3. As can be understood, the chip photoresistor R3 is easy to automate and weld, thus reducing production costs and facilitating subsequent maintenance and replacement.

[0053] Specifically, in this embodiment, the photoresistor R3 is a GT36528 chip photoresistor R3. It should be noted that the specific model of the photoresistor R3 can be selected according to actual parameters, process costs and other requirements, and is not limited here.

[0054] As a feasible implementation, the lighting circuit 2 includes a lamp array, and the lamp array includes at least one lamp string 21 .

[0055] It can be understood that in the embodiment of the present invention, a plurality of light strings 21 are used to achieve diverse lighting effects, improve visual effects, enhance user experience, and provide more visual options.

[0056] As a feasible implementation, there are multiple light strings 21 , the light strings 21 are arranged along the length direction of the circuit board 1 , and the multiple light strings 21 are arranged in an array.

[0057] It can be understood that in the embodiment of the present invention, the array arrangement of multiple light strings 21 can achieve more complex lighting effects, improve visual effects and user experience, and provide more visual options.

[0058] Specifically, in this embodiment, the number of the light strings 21 is three, and each light string 21 includes at least three LED lights connected in series.

[0059] As a feasible implementation, a plurality of light strings 21 are arranged in parallel.

[0060] As a feasible implementation, the light strings 21 are marquee light strings 21 , and the working colors or marquee speeds of different light strings 21 are the same or different.

[0061] It can be understood that in the embodiment of the present invention, more visual effect options are provided through the marquee effect of different colors and speeds, and at the same time, the user can be better assisted in confirming the working status of the connection terminal 10 through the lighting effect.

[0062] The marquee light string 21 is a special LED light string 21 that controls the on and off sequence of the LED lights so that the lights are turned on and off in a predetermined sequence, thereby forming a "moving" visual effect, similar to the dynamic effect of a horse running.

[0063] For example, in the initial state, all LEDs are off, and then they light up and off in the following order: LED 1 on; LED 1 off, LED 2 on; LED 2 off, LED 3 on; ...; LED 8 off, LED 1 on. This creates a "running" effect when viewed from a distance.

[0064] As a feasible implementation method, the running speed of the marquee can be associated with the charging voltage, and the speed of the marquee can be controlled by different voltage levels.

[0065] Specifically, the input voltage is detected using an analog-to-digital converter (A / D converter). For example, a microcontroller pin can be connected to a voltage detection circuit to read the current charging voltage. Based on the detected voltage, the ticker's speed is adjusted. For example, the following voltage levels and corresponding speeds can be set: 5V for a slower speed; 9-12V for a medium speed; and 12V and above for the fastest speed.

[0069] As a feasible implementation, the control circuit 4 includes a power management interface group, which includes a VDD interface and a VSS interface. A first capacitor is connected in parallel between the VDD interface and the VSS interface.

[0070] It can be understood that in the embodiment of the present invention, the power management interface group provides a stable power supply, and the first capacitor is connected in parallel between VDD and VSS to play a filtering role, reduce power supply noise, and improve system stability and reliability.

[0071] Please combine Figure 4 and Figure 5 As a feasible implementation method, a voltage stabilizing circuit 5 is further provided on the circuit board 1. The input end of the voltage stabilizing circuit 5 is used to be connected to an external circuit, and the output end of the voltage stabilizing circuit 5 is connected to the VDD interface.

[0072] It can be understood that in the embodiment of the present invention, the voltage stabilizing circuit 5 ensures that each component on the circuit board 1 obtains a stable voltage supply, improves the stability and reliability of the system, and ensures the normal operation of data transmission and charging functions.

[0073] Please continue reading Figure 4 , Figure 4 : is a circuit schematic diagram of the voltage stabilizing circuit 5 in this embodiment. As a feasible implementation method, the voltage stabilizing circuit 5 includes a low-voltage dropout linear regulator (shown as U2 in the figure), an input filter circuit connected in series to the input end of the low-voltage dropout linear regulator, and an output filter circuit connected in series to the output end of the low-voltage dropout linear regulator.

[0074] It can be understood that in the embodiment of the present invention, the low-voltage-dropout linear regulator can still provide a stable output voltage under a low voltage difference, and the input filter circuit and the output filter circuit reduce power supply noise. The main purpose of this circuit is to provide a stable power supply VDD for subsequent circuits after the external power supply VBUS is stabilized. This design improves the stability and reliability of the system and is applicable to various power supply environments.

[0075] As a feasible implementation, the input filter circuit includes a TVS diode DZ1 (bidirectional transient suppression diode) connected in parallel with the input of the low-dropout linear regulator. This diode limits the maximum input voltage, preventing excessive voltage from entering the circuit and providing protection. It can absorb large amounts of energy instantaneously, preventing power spikes from damaging the circuit.

[0076] As a feasible implementation, the input filter circuit includes a capacitor C2 connected in parallel with the input terminal of the low-dropout linear regulator, which serves as an input bypass capacitor to help filter out high-frequency noise in the input power supply and improve power quality.

[0077] Specifically, in this embodiment, the capacitor C2 is a 10uF / 35V electrolytic capacitor.

[0078] As a feasible implementation, the input filter circuit includes a resistor R8 connected in series with the input terminal of the low-dropout linear regulator. The resistor R8 serves as a current-limiting resistor for limiting the current flowing into the TVS diode to prevent the TVS diode from overloading.

[0079] As a feasible implementation, the filtering circuit includes a capacitor C3 connected in parallel with the output terminal of the low-dropout linear regulator, which serves as an output decoupling capacitor to further filter out high-frequency noise in the output voltage and ensure the stability of the output voltage.

[0080] Specifically, in this embodiment, the capacitor C3 is a 1 uF ceramic capacitor.

[0081] Please combine Figure 6 and Figure 7 In this embodiment, the connecting terminal 10 further includes a housing 7 , the circuit board 1 is disposed in the housing 7 , and the external connection port 6 is exposed outside the housing 7 .

[0082] As a feasible implementation, light-transmitting areas are provided on the housing 7 corresponding to the light-emitting circuit and the light-sensing circuit.

[0083] Specifically, in this embodiment, a light-transmitting plate 8 is provided on the housing 7 , and the light-transmitting area is the area defined by the light-transmitting plate 8 .

[0084] It is understandable that the light-transmitting plate 8 can effectively protect the light-emitting circuit and the light-sensing circuit from external physical damage, such as dust, moisture, impact, etc. It can also provide electromagnetic shielding to a certain extent, reducing the impact of external electromagnetic interference on the circuit.

[0091] It can be understood that the data cable 100 has the same beneficial effects as the above-mentioned connecting terminal 10, which will not be described in detail here.

[0092] Please combine Figures 1 to 8 The working principle / process of the data cable 100 is briefly described as follows:

[0093] The external power supply VBUS is connected to the voltage regulator circuit 5 through a filter circuit. The filter circuit includes a TVS diode DZ1, a resistor R8, and a capacitor C2. After stabilizing the input voltage, the voltage regulator circuit 5 outputs a stable VDD voltage to power the various components on the circuit board 1.

[0094] The photoresistor R3 detects the intensity of ambient light, and its resistance changes with the intensity of ambient light.

[0095] Photoresistor R3 and fixed resistor R6 are connected in series to form a voltage divider circuit. The output voltage of the voltage divider circuit is transmitted to microcontroller U1 through the signal input interface group (PA0 and PA1). Microcontroller U1 reads the output voltage of the voltage divider circuit through the signal input interface group and calculates the current ambient light intensity.

[0096] Based on the ambient light intensity, microcontroller U1 adjusts the brightness of lighting circuit 2. Microcontroller U1 controls the brightness of each light string 21 through a group of signal output interfaces (PB0, PB1, PB2, and PB3).
