[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] like Figures 1-3 As shown, this embodiment provides an electrical performance testing device for performing electrical performance testing on a product to be tested, the product to be tested including a terminal block 7.

[0031] The electrical performance testing equipment includes a mounting frame 1, a terminal fixing mechanism 2, and a pin moving mechanism 3. The terminal fixing mechanism 2 includes a support base 21 and a fixing cover plate 22 located on top of the support base 21. The support base 21 is mounted on the mounting frame 1. The fixing cover plate 22 can be opened and closed on the support base 21. The support base 21 is provided with a placement groove 211 for placing the terminal 7. The fixing cover plate 22 can press the terminal 7 into the placement groove 211, thereby enabling the terminal fixing mechanism 2 to install and fix the terminal 7.

[0032] Meanwhile, the ejector pin moving mechanism 3 includes a linear moving component 31 and a detection ejector pin 32. The linear moving component 31 is mounted on the mounting frame 1, and the detection ejector pin 32 is connected to the drive end of the linear moving component 31. The linear moving component 31 drives the detection ejector pin 32 to move vertically, so that the detection ejector pin 32 can contact and abut against the PIN pin of the terminal 7 vertically. Thus, during the process of the linear moving component 31 driving the detection ejector pin 32 to approach the PIN pin of the terminal 7, the detection ejector pin 32 and the PIN pin of the terminal 7 will be pressed together without being plugged in, thereby avoiding poor contact during plugging and causing detection failure. Moreover, during batch testing, the detection ejector pin 32 and the PIN pin of the terminal 7 will not be damaged. Among them, there are several placement slots 211, and each placement slot 211 corresponds to a set of detection ejector pins 32.

[0033] For example, at least one terminal fixing mechanism 2 and at least one ejector pin moving mechanism 3 are provided, and the terminal fixing mechanism 2 and the ejector pin moving mechanism 3 are provided in a one-to-one correspondence. Optionally, two terminal fixing mechanisms 2 and two ejector pin moving mechanisms 3 are provided.

[0034] Optionally, the mounting frame 1 is a box-type frame made of bakelite, and a power module and a control module are installed inside the mounting frame 1. The power module can supply power to the electrical performance testing equipment, and the control module can control the linear motion component 31 to drive the test pin 32 to move. The mounting frame 1 is equipped with an up button, a down button, and an unlock button. The control module is communicatively connected to the up button, down button, and unlock button, so that pressing the unlock button while simultaneously pressing the up button or down button can raise or lower the test pin 32, which is convenient for operators and ensures safety. Further optionally, the product to be tested is a photovoltaic inverter cooling fan. Of course, the product to be tested can also be other devices with wiring terminals 7, and this embodiment does not make specific limitations.

[0035] Specifically, the detection pin 32 is a circular pin with a spherical or umbrella-shaped head. This structure is better suited for crimping the pins of the terminal 7, ensuring good crimping contact, while also preventing damage to the pins of the terminal 7.

[0036] like Figure 1 and Figure 3 As shown, the linear motion assembly 31 includes a support plate 311, a drive cylinder 312, and a pin fixing plate 313. The support plate 311 is mounted on the mounting frame 1, the drive cylinder 312 is mounted on the support plate 311, and the detection pin 32 is mounted on the pin fixing plate 313. The drive end of the drive cylinder 312 is connected to the pin fixing plate 313 and is used to drive the pin fixing plate 313 to move vertically. Thus, the pin fixing plate 313 can drive the detection pin 32 to move vertically, thereby enabling the detection pin 32 to press or disengage from the P1N pin of the terminal 7. Optionally, the linear motion assembly 31 also includes a baffle 314, which is mounted on the pin fixing plate 313. The detection pin 32 and the pin wiring are located between the baffle 314 and the pin fixing plate 313. By setting the baffle 314, the pin wiring of the detection pin 32 can be constricted, preventing the detection pin 32 from becoming messy during movement. The detection pin 32 can be fixed to the pin fixing plate 313 by means of threaded connection, adhesive or other methods.

[0037] like Figure 1 and Figure 2As shown, the placement groove 211 includes a positioning groove 2111 and a through groove 2112 communicating with the positioning groove 2111. The through groove 2112 passes through one end of the bearing base 21 in the horizontal direction. The terminal 7 is embedded in the positioning groove 2111. Part of the terminal line of the terminal 7 can be placed in the through groove 2112. Thus, the terminal 7 can be positioned and installed through the positioning groove 2111 to ensure the crimping accuracy of the detection pin 32 to the PI N pin of the terminal 7 and prevent poor contact. The through groove 2112 can avoid part of the terminal line of the terminal 7 to facilitate the installation of the terminal 7 in the placement groove 211. The fixed cover plate 22 has a through hole 221, through which the detection pin 32 can pass and contact the PI N pin of the connecting terminal 7 in a vertical direction. This allows the fixed cover plate 22 to completely cover the terminal 7, and the through hole 221 guides the detection pin 32, further improving the crimping accuracy of the detection pin 32 to the PI N pin of the terminal 7. Multiple detection pins 32 and through holes 221 are provided in a one-to-one correspondence.

[0038] In one embodiment, the fixed cover plate 22 is hinged to the support base 21. Rotating the fixed cover plate 22 can press the terminal 7 into the placement groove 211, or open the placement groove 211 to facilitate the placement of the terminal 7.

[0039] In one embodiment, the supporting base 21 is provided with a first magnetic element 212, and the fixing cover plate 22 is provided with a second magnetic element 222. The first magnetic element 212 can magnetically engage with the second magnetic element 222, thereby fixing the fixing cover plate 22 on the supporting base 21 after it is closed, and thus achieving the fixed pressing of the terminal 7. The operation is simple, convenient and quick. For example, the fixing cover plate 22 is a rectangular plate, with one side of the fixing cover plate along the width direction hinged to the supporting base 21, and the other side provided with the second magnetic element 222.

[0040] In one embodiment, one of the supporting base 21 and the fixing cover 22 is provided with a hook, and the other is provided with a protrusion. The hook can engage with the protrusion, thereby fixing the fixing cover 22 on the supporting base 21 after it is closed through the engagement connection between the hook and the protrusion, thus achieving a fixed and secure connection of the terminal 7. Exemplarily, when one of the supporting base 21 and the fixing cover 22 is provided with a hook and the other with a protrusion, a first magnetic element 212 and a second magnetic element 222 can also be provided. Optionally, when only the hook and the protrusion are used, the supporting base 21 is also provided with an elastic positioning pin. The elastic positioning pin assists in the engagement between the hook and the protrusion, ensuring the stability of the engagement and facilitating the adaptation of irregularly shaped terminal 7.

[0041] Furthermore, the electrical performance testing equipment also includes a signal generating device 4, a signal acquisition device 5, and a feedback device 6. All three devices are mounted on the mounting frame 1. The signal generating device 4 and signal acquisition device 5 are communicatively connected to the testing pin 32, and the feedback device 6 is communicatively connected to the signal acquisition device 5. Thus, the signal generating device 4 can emit relevant control signals to control the operation of the product under test. The signal acquisition device 5 then acquires the corresponding feedback signal and performs FD feedback signal capture and measurement. The combined signals from the signal generating device 4 are finally fed back through the feedback device 6. The signal generating device 4 is either a PWM controller or an ARM controller. The PWM controller provides precise control, efficient adjustment, and lower cost, while the ARM controller offers higher performance, stronger expandability, but higher cost. Optionally, the feedback device 6 includes at least one of a display panel, indicator lights, and an alarm. The display panel, indicator lights, and alarm are used individually or in combination to meet the actual signal feedback requirements and determine the health status of the product under test. Alternatively, the signal acquisition device 5 can be a voltage acquisition device, which can be used to compare the acquired voltage to easily determine the health status of the detection equipment.

[0042] The operation procedure of the electrical performance testing equipment in this embodiment is as follows:

[0043] Place the terminal 7 of the product to be tested into the placement slot 211, and press the terminal 7 down with the fixing cover plate 22;

[0044] Pressing the unlock button and the lowering button simultaneously drives the cylinder 312 to drive the pin fixing plate 313 to lower the detection pin 32 and press it against the P1 N pin of the terminal 7.

[0045] Power the product to be tested and adjust the control switch of the PWM controller or ARM controller;

[0046] The performance of the product to be tested is judged by the feedback device 6;

[0047] After the test is completed, press the unlock button and the rise button at the same time to return the test pin 32 to its original position, open the fixing cover 22 and take out the terminal 7.

[0048] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
