[0025] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] Reference Figure 1This paper illustrates a testing device for a surface mount transformer according to an embodiment of this application. The device includes: a terminal block 101 with electrodes 102 corresponding to the pins of the product under test (DUT). The electrodes 102 are electrically connected to a test box 103 located at the lower end of the terminal block 101. The test box 103 provides test terminals 133 arranged in a preset order. During testing, the DUT is connected to the electrodes 102 of the terminal block 101. The test terminals provided in the lower test box 103 are used to electrically connect to testing instruments or equipment, achieving efficient testing. This solves the problem that current surface mount transformer testing requires manual testing, which is inefficient, prone to errors, and leads to inaccurate testing. By connecting the test equipment through the aforementioned test terminals, the stability of the electrical connection is ensured, improving test accuracy and speed.

[0027] In the embodiments of this application, such as Figure 2 As shown, the terminal block 101 is provided with a test slot 111 for placing a surface mount transformer; the electrode 102 is vertically disposed on both sides of the test slot 111. The test slot 111 is used to adapt to the surface mount transformer to be tested, preventing the surface mount transformer from shifting position, which would cause the leads to not maintain a good electrical connection with the electrode 102, thereby ensuring the accuracy of the test and improving the test efficiency; by setting electrodes corresponding to the pins of the product under test, precise docking can be achieved, reducing false tests and missed tests caused by human identification errors. The test slot can adapt to the surface mount transformer, preventing its position from shifting, ensuring a good electrical connection between the pins and the electrode, and further ensuring the accuracy of the test.

[0028] By setting up a test slot 111 and arranging elastic pin electrodes 102 on both sides of the slot, the physical dimensions of the surface mount transformer are directly adapted to ensure that the pin position is in close contact with the electrode. Through the structure of the test slot 111, poor contact caused by pin offset or flatness deviation is effectively prevented, thereby improving the reliability of electrical connection.

[0029] The following will further describe a testing device for a patch transformer according to various exemplary embodiments of this application.

[0030] In the embodiments of this application, the electrode 102 is an elastic needle structure, with its elastic head facing upwards and its lower end fixed and penetrating through the terminal block 101. Figure 2As shown, the terminal block 101 is movably connected to the upper end of the test box 103 via a guide post 112; a spring 113 is sleeved on the guide post 112; the test box 103 has a test hole 131 corresponding to the electrode 102; the lower end of the electrode 102 and the lower end of the test hole 131 are both tapered structures; the test hole 131 is electrically connected to the test terminal 133. Due to the tapered structure at the lower end of the electrode 102 and the test hole 131, during testing, pressing down on the terminal block 101 causes the lower end of the electrode 102 to be inserted into the test hole 131, allowing the electrode 102 to be electrically connected to the test terminal 133. The guide post 112 and spring 113 structure ensure that the electrode 102 can be accurately inserted into the test hole 131 during testing. After the test, the spring 113 automatically resets the terminal block 101.

[0031] The tapered structure design of electrode 102 and test hole 131 allows for quick electrical connection by pressing down the terminal block. The guide post 112 and spring 113 ensure smooth operation and automatic reset after testing, saving operation time and facilitating efficient testing. The terminal block 101 and test box 103 are movably connected via guide post 112 and spring 113, which not only facilitates operation but also ensures accurate insertion of electrode 102 into test hole 131, enhancing the stability and reliability of the equipment.

[0032] In an embodiment of this application, a test platform 132 is further provided at the lower position of the test box 103, and the test terminals 133 are disposed on the test platform 132. By setting the test platform 132 inside the test box 103, the test terminals are arranged in a reasonable manner, facilitating connection and operation. The test terminals 133 are screw terminals.

[0033] Furthermore, it also includes a withstand voltage tester 104, a comprehensive tester 105, and an interlayer tester 106; the withstand voltage tester 104 is electrically connected to test terminal A, the comprehensive tester 105 is electrically connected to test terminal B, and the interlayer tester 106 is electrically connected to test terminal C; test terminals A, B, and C are electrically connected to test terminal 133.

[0034] By connecting the withstand voltage tester 104, the comprehensive tester 105, and the interlayer tester 105 to the equipment, and connecting the test terminals 133 through different test terminals, multiple functional tests can be realized, meeting the needs of comprehensive testing of surface mount transformers and improving the practicality and functionality of the equipment.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.
