Description

Technical Field

[0002] In the current electronic component manufacturing and testing industry, the performance of the test device directly determines the accuracy of product quality assessment. However, traditional electronic component electrical performance test devices often face challenges such as unstable docking and large signal transmission interference during the test process. Specifically, the connection between the test pen and the tester often relies on a simple plug-in structure. This design is easily affected by improper operation or long-term wear and tear, resulting in poor contact, signal interruption or distortion, which seriously affects the accuracy and stability of the test. In addition, slight vibrations or offsets of the circuit board during the test process may also introduce measurement errors, making the test results unreliable.

[0003] With the rapid development of the electronic components industry, the working environment of test equipment has become increasingly complex and changeable, placing higher demands on the durability and reliability of the equipment. However, existing test devices are often unable to cope with harsh environments (such as high humidity, dust, etc.), and internal components are easily damaged, resulting in equipment performance degradation or even failure. In addition, some test devices have deficiencies in structural design, such as poor sealing and imperfect reset mechanisms, which also increase the risk of equipment damage.

[0004] User experience and maintenance convenience are important indicators for measuring the quality of test equipment. However, traditional test equipment often has shortcomings in these two aspects. For example, the complex operation interface, cumbersome operation steps, and difficulty in disassembling and assembling key components not only increase the user's learning cost and difficulty of use, but also reduce the maintenance efficiency of the equipment.

DETAILED DESCRIPTION

[0032] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention is further described below in conjunction with the accompanying drawings.

[0033] Example

[0034] like Figure 1-Figure 7As shown, an electronic component electrical performance test device proposed in one embodiment of the present invention is mainly composed of an electrical performance tester and a test pen 5. The tester is composed of a tester rear shell 1 and a tester front shell 2 that are snap-connected, and a circuit board 3 is installed inside, and an electrical docking head 4 is electrically installed on the circuit board. The test pen 5 is connected to the electrical plug 7 through a connecting wire 6, and the electrical plug 7 is docked with the electrical docking head 4 through an open groove 8 on the side of the tester shell. To prevent the electrical plug 7 from falling off, a limiting mechanism is provided on the side, including a lap slider 15 and a plug rod 16 in a rectangular groove 10 on a strip plate 9, and the end of the plug rod 16 is an iron limiting plate 17. In addition, a sealing structure is provided between the tester rear shell 1 and the tester front shell 2 to ensure the stability of the internal environment. A display screen is provided on the front of the tester front shell 2, and is protected by a protective structure; the accuracy of the test is ensured by the stable docking of the test pen 5 with the tester. The limiting mechanism and the sealing structure improve the reliability and durability of the device, and the protective structure effectively protects the display screen.

[0035] The reset assembly includes a vertical fixing rod 12 in the strip placement groove 11, a spring 13 is sleeved on the vertical fixing rod 12, and a sliding sleeve 14 slides on the vertical fixing rod 12 and is connected to the overlapping slider 15. When the electrical plug 7 is inserted and pushes the overlapping slider 15, the spring 13 is compressed; after the electrical plug 7 is pulled out, the spring 13 recovers its deformation and pushes the overlapping slider 15 to reset; the reset assembly ensures that the overlapping slider 15 can automatically reset after the electrical plug 7 is pulled out, so as to prepare for the next docking and improve the convenience of operation.

[0036] Furthermore, the upper end of the spring 13 is fixedly connected to the end wall of the strip placement groove 11, and the lower end is fixedly connected to the upper end surface of the sliding sleeve block 14. When the electrical plug 7 is pulled out, the spring 13 uses its elastic force to push the sliding sleeve block 14 to move upward, thereby driving the overlapping slider 15 to reset; the disassembly and assembly parts include the plug-in slot 18 on the iron limit plate 17 and the magnetic suction block 19 at the end of the plug-in rod 16. The magnetic suction block 19 is adsorbed and connected to the inner bottom wall of the plug-in slot 18 to achieve the fixation of the iron limit plate 17 and the plug-in rod 16. When disassembly is required, the magnetic force can be overcome to separate.

[0037] The design of the disassembly and assembly parts simplifies the disassembly and assembly process of the iron limit plate 17, making it easy to maintain and replace.

[0038] Furthermore, the protective structure includes a protective shell 20 that is buckled on the periphery of the strip plate 9. The strip plate 9 is provided with a guide groove 21. The card slide plate 22 slides in the guide groove 21 through the guide slide bar 23, thereby ensuring the stable sliding of the protective shell 20 while limiting the separation of the tester rear shell 1 and the tester front shell 2; the protective structure effectively protects the display screen from external impacts, while ensuring the stability of the tester shell.

[0039] Furthermore, the sealing structure is composed of a sealing insert ring 24 on the tester rear housing 1 and a sealing slot 25 on the tester front housing 2. The sealing insert ring 24 is inserted into the sealing slot 25 to achieve the sealing of the tester housing; the sealing structure effectively prevents external dust, moisture, etc. from entering the tester, ensuring the accuracy of the test and the long-term stable operation of the equipment.

[0040] Among them, the design size of the sealing ring 24 is compatible with the opening size of the sealing slot 25, ensuring that the sealing ring 24 can be tightly inserted into the sealing slot 25 to form an effective seal; the tester housing is tightly sealed and the waterproof and dustproof performance of the equipment is improved.

[0041] Furthermore, a plug hole 26 is provided on the circuit board 3, a plug column 27 is fixed on the inner wall of the front housing 2 of the tester, and a limit ring piece 28 is provided on the periphery of the plug column 27. After the plug column 27 is inserted into the plug hole 26, the limit ring piece 28 contacts the surface of the circuit board 3 to fix the circuit board 3; the mounting structure of the circuit board 3 is stable and reliable, ensuring the stable position of the circuit board 3 during the test process and improving the test accuracy.

[0042] Among them, after the plug-in column 27 is inserted into the plug-in hole 26, the limiting ring piece 28 gradually contacts and presses the surface of the circuit board 3 during the insertion process of the plug-in column 27, thereby fixing the circuit board 3; the circuit board 3 is firmly fixed, avoiding loosening or displacement due to vibration and other reasons during the test.
