[0003] In the capacity verification project, a residual voltage of a measured sample after the power supply is disconnected is needed to be measured by a device which does not have a significant impact on the measured value. The input circuit of an electronic and electrical product often contains an energy storage element, and the energy storage element is fully charged after being powered for a period of time. After the plug is pulled out, if there is no effective discharge circuit or the amount of electricity in the energy storage element is too large and does not match the discharge speed of the discharge circuit, it will bring a shock feeling to the personnel who touches the plug.

[0004] If a variable resistor or a variable capacitor is used in the traditional capacity verification device, the instrument is prone to misalignment during transportation, so the traditional capacity verification project needs to be designed and manufactured separately. A special test plug is needed, and the working state of the test device under different voltages also needs to be specially manufactured according to each test voltage.

[0060] In the embodiment, when the built-in test circuit is the module one, the built-in test circuit is used for testing the discharge capacity of all laboratories in the same test group, either alone as a test sample group or in combination with at least one built-in test circuit as a module one.

[0061] In the embodiment, when the built-in test circuit is the module two or the module three, the built-in test circuit is used for testing the discharge capacity of all laboratories in the same test group, in combination with at least one built-in test circuit as a module one.

[0062] The laboratory discharge capacity verification plug of the present application is shown in Figure 1 The built-in test circuit is shown in Figure 2 The principle of the capacity verification plug as a module one is shown in Figure 3

[0063] The second embodiment of the present application provides a laboratory discharge capacity verification method, which is implemented by using the laboratory discharge test capacity verification plug described above, and the method comprises the following steps.

[0064] In step S100, the total number of samples, the equipment parameters and the combination mode of the discharge capacity verification plugs required are determined according to the test voltage value or the number of test voltage values required by the discharge capacity verification test.

[0065] In step S200, the discharge capacity verification plug group is manufactured for each laboratory in the same test group based on the total number of samples and the equipment parameters.

[0066] In step S300, the discharge capacity of each laboratory in the same test group is tested by using the discharge capacity verification plug group to connect the test system in all combination modes.

[0067] In the embodiment, the step S300 specifically comprises the following steps.

[0068] In step S310, the combination mode contains at least one capacity verification plug with a built-in test circuit as a module one, and any capacity verification plug with a built-in test circuit as a module one is used as a connection plug.

[0069] In step S320, the other capacity verification plugs in the combination mode are inserted into the connection plug to obtain a test group. ​

[0070] Step S330, after the test group is pretreated in the preset test environment, the test group is connected to the test system;

[0071] Step S340, after the test system applies the laboratory discharge voltage to the test group for a preset discharge duration, the residual voltage of the plug is recorded by the oscilloscope within a preset recording time;

[0072] Step S350, the method of steps S310-S340 is repeated until the residual voltage of the plug connected to the test system in all combination modes is recorded, and a residual voltage set is obtained;

[0073] Step S360, the discharge capacity of the target laboratory is calculated based on the residual voltage set.

[0074] In the embodiment, the laboratory discharge voltage specifically refers to:

[0075] The oscilloscope is used to perform a discharge test on the plug group to be tested.

[0076] The voltage of 220V, 50Hz alternating current is applied, and the voltage of each plug in the plug group at a plurality of preset times after discharge is tested, and the voltage reflects the discharge capacity of the plug group to be tested.

[0077] In the embodiment, the discharge capacity of the target laboratory is calculated based on the residual voltage set, and specifically refers to:

[0078]

[0079] Wherein, U represents the voltage of the test system after discharge for a preset time, U0 represents the voltage peak value, t represents the discharge time, R represents the total resistance of the test group, C represents the capacitance of the test group, and RC represents the time constant.

[0080] As long as different laboratories perform discharge tests on the same test group, and the discharge capacity test result deviation is less than a preset deviation threshold, it indicates that the discharge capacity of each laboratory meets the capacity verification standard.

[0081] The principle of the traditional discharge capacity verification is shown in Figure 4 It is assumed that 5 test voltages need to be verified, and 5 samples are needed. Once a capacity verification project is completed, the samples cannot be reused or combined. If other discharge voltage values are needed, new special samples must be made. In order to ensure that the discharge capacity of each voltage segment is verified, multiple voltages need to be tested. The discharge test principle of the present application is shown in Figure 5 By combining different plugs, a plurality of different discharge voltage values can be provided, which can well meet the requirements of capacity verification, save costs, and greatly increase the flexibility of capacity verification samples. More specifically, five samples are used alone, and two sample combinations can provide 5 test voltages, and any selection of three sample combinations can provide 10 test voltages two sample combinations can provide 5 test voltages, and any selection of three sample combinations can provide 10 test voltages two sample combinations can provide 5 test voltages, and any selection of three sample combinations can provide 10 test voltages 5 combinations can provide 1 test voltage, and a total of 31 test voltages can be provided. Multiple samples can be provided in 31 combinations by the parallel voltage formula of multiple RC circuits to provide a test voltage every 10V in the rated voltage range. Only 5 plugs with capacitors and a minimum of 5 other plugs are required to achieve this. The present application tests the discharge capacity of the laboratory under different voltage conditions.

[0090] The second movable clamping device can be selected by image recognition or by setting a fixed storage position for each socket.

[0091] The automatic socket replacement device can be arranged near the socket of the test system, or can be arranged in the form of a movable trolley or a mold for alignment before use; the movable clamping device is clamped from different directions, such as the first movable clamping device being clamped in the left and right directions of the socket, and the second movable clamping device being clamped in the front and back directions of the socket; and five storage slots can be arranged on the left and right sides of the socket for storing the socket to facilitate selection of the second movable clamping device; the first movable clamping device only performs up-down translation and clamps the socket to be separated; and all sockets can be clamped, assembled and separated by up-down translation and left-right translation of the second movable clamping device; by setting a preset replacement mode and a control program, the automatic socket replacement device can be commanded to complete discharge capacity verification in all combination modes and record the results, and the whole process does not require manual intervention, the experimental variables are few, and the control is accurate.
