[0031] This embodiment discloses a Type-C on / off control circuit, suitable for automated testing equipment. Please refer to... Figures 1 to 4 The Type-C on / off control circuit includes a Type-C interface module 100, a signal input module 200, an on / off control module 300, and a status feedback module 400. The Type-C interface module 100 has a first input terminal and a first output terminal, and is used for Type-C interface conversion.

The on / off control module 300 has a conducting terminal and a disconnecting terminal; the conducting terminal is connected to the first input terminal, and the disconnecting terminal is connected to the first output terminal. The on / off control module 300 is equipped with a relay, which is used to control the circuit on / off of the Type-C interface module 100 according to the signal from the second input terminal. The status feedback module 400 is connected to the on / off control module 300, and is used to indicate the on / off state of the Type-C interface module 100. During testing, the signal input module 200 sends a control signal to the on / off control module 300. Upon receiving the control signal, the on / off control module 300 controls the circuit of the Type-C interface module 100 to switch on and off according to the control signal. The status feedback module 400 feeds back the on / off status of the Type-C interface module 100 to the automated testing equipment in real time. The automated testing equipment monitors and records the on / off status of the Type-C interface. By providing a simple on / off control circuit, the complexity and maintenance difficulty of the system are reduced, ensuring the stable and reliable on / off status of the Type-C interface module 100.

[0032] Please refer to Figure 2 and Figure 3 The Type-C interface module 100 includes a male connector module 110 and a female connector module 120. Through the cooperation of the male connector module 110 and the female connector module 120, the Type-C interface module 100 converts a Type-C male connector to a Type-C female connector. The male connector module 110 and the female connector module 120 are interconnected via their respective TX1+, TX1-, RX1+, RX1-, TX2+, TX2-, RX2+, and RX2- pins, thus achieving the Type-C male to female connector function.

[0033] Please refer to Figure 2 The male connector module 110 has multiple VBUS_IN pins used as first input terminals, and the male connector module 110 is connected to the on / off control module 300 through the VBUS_IN pins. For example, it has multiple VBUS_IN pins used as first input terminals, such as... Figure 2 The four VBUS pins.

[0034] Please refer to Figure 3 The female connector module 120 has multiple VBUS_OUT pins used as first output terminals, and the female connector module 120 is connected to the on / off control module 300 through the VBUS_OUT pins. For example, it has multiple VBUS_IN pins used as first input terminals, such as... Figure 2 The four VBUS pins.

[0035] Please refer to Figure 4 The on / off control module 300 has a fifth pin and a sixth pin. The fifth pin is connected to the VBUS_IN pin, and the sixth pin is connected to the VBUS_OUT pin. When the fifth pin of the on / off control module 300 is connected to the sixth pin, the first input terminal and the first output terminal of the Type-C interface module 100 are turned on, and the Type-C interface module 100 has an output.

[0036] Please refer to Figure 4 The signal input module 200 uses an XH connector J103, model number W7910211120AB. The signal input module 200 is used to receive control signals from automated testing equipment. For example, the XH connector J103 has two pins, uses a DIP package with a pin pitch of 2.5mm, a molding height of 7.0mm, and a pin length of 3.40mm.

[0037] Please refer to Figure 4The on / off control module 300 has a second pin, a third pin, a fourth pin, and a seventh pin. The third pin is connected to the USB_GND_IN pin of the male interface module 110, and the fourth pin is connected to the USB_GND_OUT pin of the female interface module 120. When the third pin of the on / off control module 300 is connected to the fourth pin, the second and seventh pins are disconnected, and the Type-C interface module 100 has an output. By using a reliable on / off control module 300, the on / off state of the Type-C interface module 100 is ensured to be stable and reliable.

[0038] Please refer to Figure 4 The on / off control module 300 uses a relay K101 of model AGQ20024 to realize the function of a double-pole double-throw switch. For example, the relay K101 adopts a DIP package, has a double-pole double-throw contact type, a coil voltage of DC 24V, and a rated current of 2A. The relay K101 is installed via DIP packaging and connects to the male interface module 110 and the female interface module 120 using its double-pole double-throw contacts. Based on changes in the input signal from the signal input module 200, it automatically connects or disconnects the circuit, enabling precise circuit control and realizing the function of a double-pole double-throw switch. After receiving an external DC 24V control voltage, the electromagnet inside the relay K101 is activated, generating a magnetic field that causes the metal contact piece in the relay K101 to move, thereby switching to the corresponding contact position and completing the on / off control of the circuit. This ensures that the circuit can operate stably under an effective operating current of 2A, achieving efficient and reliable circuit control.

[0039] Please refer to Figure 4 The status feedback module 400 includes a first resistor R103 and a light-emitting diode D101. The first end of the first resistor R103 is connected to the first pin of the on / off control module 300, and the second end of the first resistor R103 is electrically connected to the first end of the light-emitting diode D101. The second end of the light-emitting diode D101 is connected to the eighth pin of the on / off control module 300. For example, the first resistor R103 is SMD packaged, with a resistance of 10KΩ, an accuracy of ±1%, and a rated power of 1 / 10W. The light-emitting diode is SMD packaged and has a rated voltage of 3.3V. During operation, the status feedback module 400 indicates the on / off status based on the on / off state of the Type-C interface. For example, when the Type-C interface is connected, the indicator light will illuminate; when the Type-C interface is disconnected, the indicator light will turn off; if an abnormality occurs, the indicator light will flash as a fault indication.

[0040] The circuit working principle of this embodiment is as follows:

[0041] When automated testing equipment needs to test products using a Type-C interface, it first sends a control signal to the on / off control module 300 via the signal input module 200. Upon receiving the control signal, the on / off control module 300 controls the circuit of the Type-C interface module 100 to open or close according to the signal. Simultaneously, the status feedback module 400 feeds back the on / off status of the Type-C interface module 100 to the automated testing equipment in real time. The automated testing equipment monitors and records the on / off status of the Type-C interface for subsequent testing and analysis of the product.

[0042] This embodiment has the following beneficial effects:

[0043] 1. Simple circuit design: By simplifying the circuit design, the complexity of the system and the difficulty of maintenance are reduced.

[0044] 2. Stable on / off control: A reliable on / off control module is used to ensure that the on / off state of the Type-C interface is stable and reliable.

[0045] 3. Low-cost implementation: The use of low-cost circuit components reduces the overall cost of the solution.

It can automatically control the on / off state of the Type-C interface, is easy to operate, achieves fully automated control of the testing process, reduces manual intervention and errors, and improves testing stability.
