Technical Field

[0001] This application relates to the field of testing technology, specifically to an auxiliary tooling and testing equipment for the output power of a USB-C adapter. Background Technology

[0002] Currently, many electronic devices (such as laptops, thick and thin terminals, etc.) are used with adapters. When performing input tests on these electronic devices, since the output of the adapter is the input of the electronic device, the voltage, current, and power of the electronic device's input are usually monitored by monitoring the voltage, current, and power of the adapter's output.

[0003] However, in some technologies, monitoring the voltage, current, and power at the adapter's output can damage the adapter, causing it to be discarded after testing, resulting in high testing costs. Utility Model Content

[0011] In some embodiments, the first adapter board includes a first communication port, and the second adapter board includes a second communication port.

[0013] In some embodiments, the first communication port includes a first additional signal port, and the second communication port includes a second additional signal port. The first additional signal port is connected to the second additional signal port for data and audio transmission between the first adapter board and the second adapter board.

[0014] In some embodiments, the first adapter is a female connector and the second adapter is a male connector.

[0015] In some embodiments, the power meter further includes a controller and a detection result output device. The controller is connected to the current detection terminal, the voltage detection terminal, and the detection result output device.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Before describing the auxiliary tooling for the output power of the C-port adapter in this application, the adapter board and the adapter will be introduced first.

[0033] An adapter board is an intermediary layer technology device that performs interface conversion, level conversion, and pin expansion. Interface conversion refers to converting signals from one interface type to another, such as converting a USB (Universal Serial Bus) signal to an HDMI (High Definition Multimedia Interface) signal. Level conversion addresses inconsistencies in the voltage levels of different device interfaces by using an adapter board to facilitate normal communication and data transmission between devices. Pin expansion allows an adapter board to add more signal pins to a device interface when its signal pins are insufficient to meet specific needs.

[0034] Adapters can include power adapters, network adapters, etc. Power adapters can perform voltage conversion, including but not limited to converting voltage type and voltage magnitude. For example, they can convert AC to DC, or 150V DC to 15V DC, or 220V AC to 5V DC. This allows them to provide the required operating voltage for different electronic devices. For instance, laptops typically require 15V DC. If a laptop is directly connected to a 220V AC power source, it will inevitably be damaged due to excessive voltage. In this case, a power adapter can be connected between the laptop and the 220V AC power source. The power adapter converts the 220V AC voltage to 15V DC and outputs the converted 15V DC voltage to the laptop to power it. The adapters described below in this application primarily refer to power adapters.

[0035] Currently, in some technologies, when conducting input tests on electronic devices that use adapters, since the adapter's output terminal is the electronic device's input terminal, the adapter's output cable is typically cut to expose the positive and negative terminals, which are then connected to a power meter. This allows the power meter to monitor the current, voltage, and power at the adapter's output terminal, and consequently, the current, voltage, and power at the electronic device's input terminal.

[0036] Among these technologies, on the one hand, each input test on an electronic device will damage a power meter, resulting in high testing costs; on the other hand, each time an electronic device is tested, the output cable of the adapter needs to be cut and the positive and negative terminals inside the exposed cable connected to the power meter, which is a cumbersome process and has low testing efficiency.

[0037] Therefore, this application provides an auxiliary fixture for adjusting the output power of a USB-C adapter, which can solve the above problems. (See also...) Figure 1 This is a schematic diagram of an auxiliary tooling 100 provided in one embodiment of this application. Figure 1 In the middle, the auxiliary tooling 100 includes a first adapter plate 11, a second adapter plate 12 and a power meter 13.

[0038] The first adapter board 11 includes a first power supply terminal 111, a first ground terminal 112, and a first adapter terminal 113 for connecting the adapter 14. The first power supply terminal 111 and the first adapter terminal 113 are connected in series. Specifically, the first adapter terminal 113 is mainly used to connect the output terminal of the adapter 14. In this way, the output terminal of the adapter 14, the first adapter terminal 113, and the first power supply terminal 111 are connected in series, so that the current at the output terminal of the adapter 14 is the same as that at the first power supply terminal 111.

[0039] In this embodiment, considering that the output terminal of adapter 14 is male, the first adapter terminal 113 can be female. This facilitates connection with adapter 14.

[0040] The second adapter board 12 includes a second power supply terminal 121, a second ground terminal 122, and a second adapter terminal 123 for connecting the load device 15. The second power supply terminal 121 and the second adapter terminal 123 are connected in series. Specifically, the load device 15 refers to an electronic device that needs to be tested for input, including but not limited to laptops, thick and thin terminals, etc.

[0041] In this embodiment, considering that some load devices 15 are connected to the second adapter 123 via a female connector, the second adapter 123 can be a male connector.

[0042] The power meter 13 includes a current detection terminal 131 and a voltage detection terminal 132. The current detection terminal 131 is connected in series between the first power supply terminal 111 and the second power supply terminal 121. The voltage detection terminal 132 is connected between the first power supply terminal 111 and the first ground terminal 112, and is also connected to the second power supply terminal 121 and the second ground terminal 122.

[0043] It is understandable that, since the current sensing terminal 131 is connected in series between the first power supply terminal 111 and the second power supply terminal 121, and the output terminal of the adapter 14 is connected in series with the first power supply terminal 111, the current magnitudes of the output terminal of the adapter 14, the first power supply terminal 111, the current sensing terminal 131, and the second power supply terminal 121 are equal, and all are equal to the current magnitude of the output terminal of the adapter 14. Furthermore, since the second power supply terminal 121 is connected in series with the second adapter terminal 123, and the second adapter terminal 123 is used to connect the load device 15, the current magnitude of the second adapter terminal 123 is equal to the current magnitude of the output terminal of the adapter 14, and the current magnitude of the second adapter terminal 123 is the same as the input current magnitude of the load device 15.

[0044] Therefore, by detecting the current at the current detection terminal 131, the power meter 13 can detect the current at the output terminal of the adapter 14 and the input current of the load device 15.

[0045] Furthermore, since the first power supply terminal 111 is connected to the first adapter terminal 113, and the first adapter terminal 113 is connected to the adapter 14, it can be understood that the adapter 14 supplies power to the load device 15 through the first power supply terminal 111, the second power supply terminal 121, and the second adapter terminal 123. Ignoring the resistance of the wires, the voltages at the first power supply terminal 111 and the second power supply terminal 121 can be equal, and these voltages can be understood as the input voltage of the load device 15. Therefore, by connecting the first power supply terminal 111 and the second power supply terminal 121 to the voltage detection terminal 132 of the power meter 13, and by connecting the first ground terminal 112 and the second ground terminal 122 to the voltage detection terminal 132 of the power meter 13, the power meter 13 can determine the input voltage of the load device 15 by detecting the voltage at the voltage detection terminal 132.

[0046] Normally, when performing input testing on load device 15, the voltage supplied by adapter 14 to load device 15 can be relatively stable, that is, the voltages at the first power supply terminal 111 and the second power supply terminal 121 can be relatively stable. However, as the power consumed by load device 15 changes, the output current of adapter 14 (i.e., the input current of load device 15) can change dynamically, meaning the current at the first power supply terminal 111 and the second power supply terminal 121 can change dynamically. For example, assuming that the CPU in load device 15 is operating in a non-full-load state, the output current of adapter 14 is 5 mA. Based on this, when the CPU's operating state is adjusted from a non-full-load state to a full-load state, because the power consumed by the CPU increases, and the voltages at the first power supply terminal 111 and the second power supply terminal 121 are relatively stable, the output current of adapter 14 will inevitably increase, for example, to 10 mA. The so-called input testing of load device 15 is to detect whether its input current, power, etc., exceed the rated values ​​when load device 15 is in different operating states.

[0047] Furthermore, considering that the voltages at the first power supply terminal 111 and the second power supply terminal 121 are equal, when performing voltage detection, only one of the first power supply terminal 111 and the second power supply terminal 121 needs to be connected to the voltage detection terminal 132 of the power meter 13. For example, referring to... Figure 2 Another embodiment of this application provides a schematic diagram of the auxiliary tooling 200 module. Figure 2 and Figure 1 They are basically similar, with the main differences being: Figure 2 In this configuration, only the first power supply terminal 211 and the first ground terminal 212 of the first adapter board 21 are connected to the voltage detection terminal 232 of the power meter 23. This simplifies the circuit wiring of the auxiliary fixture 200 and reduces the circuit manufacturing cost of the auxiliary fixture 200.

[0048] In some other embodiments, the second power supply terminal 221 and the second ground terminal 222 of the second adapter board 22 may be connected to the voltage detection terminal 232 of the power meter 23. The appropriate option can be selected based on actual needs.

[0049] In summary, in the auxiliary tooling of some embodiments of this application, since the first power supply terminal of the first adapter board is connected to the adapter via the first adapter terminal, and the first power supply terminal is connected in series with the second power supply terminal of the second adapter board via the current detection terminal of the power meter, and the second power supply terminal is connected to the load device via the second adapter terminal, the power meter can determine the input current of the load device by detecting the current at the current detection terminal. Furthermore, since the voltage detection terminal of the current meter is connected to the first power supply terminal and the first ground terminal of the first adapter board, and / or connected to the second power supply terminal and the second ground terminal of the second adapter board, the power meter can determine the input voltage of the load device by detecting the voltage at the voltage detection terminal. Based on the current detected by the current detection terminal and the voltage detected by the voltage detection terminal, the input power of the load device can be determined. Thus, input testing of the load device can be performed. During the input testing process, due to the introduction of the first and second adapter boards, it is not necessary to cut the output wires of the adapter, allowing the adapter to be reused repeatedly, thereby reducing adapter wear and lowering testing costs.

[0050] Secondly, since there is no wear and tear on the auxiliary tooling during the input testing of the load equipment, the auxiliary tooling can be reused, thus achieving the goal of reducing testing costs.

[0051] Furthermore, when performing input tests on load devices using the auxiliary tooling based on this application, it is only necessary to connect the first adapter board, the second adapter board, and the corresponding terminals of the power meter, eliminating the need for wire cutting operations, which greatly simplifies the wiring operations between devices and improves testing efficiency.

[0053] The voltage detection terminal 332 includes a positive voltage detection terminal 3321 and a negative voltage detection terminal 3322. The positive voltage detection terminal 3321 is connected to the negative voltage detection terminal 3322. The positive voltage detection terminal 3321 is connected to the first power supply terminal 311, and the negative voltage detection terminal 3322 is connected to the first ground terminal 312. The positive voltage detection terminal 3321 is connected to the second power supply terminal 321, and the negative voltage detection terminal 3322 is connected to the second ground terminal 322.

[0054] In the current detection terminal 331, different ports are set to connect to the first power supply terminal 311 and the second power supply terminal 321 respectively. In the voltage detection terminal 332, different ports are set to connect to the first power supply terminal 311 and the first ground terminal 312 respectively, as well as to connect to the second power supply terminal 321 and the second ground terminal 322. This can reduce the difficulty of circuit design and facilitate the power meter 33 to perform voltage and current detection.

[0055] In other embodiments, the positive voltage detection terminal 3321 can be connected to the first power supply terminal 311, and the negative voltage detection terminal 3322 can be connected to the first ground terminal 312; or the positive voltage detection terminal 3321 can be connected to the second power supply terminal 321, and the negative voltage detection terminal 3322 can be connected to the second ground terminal 322.
