[0023] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.
[0024] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.
[0025] Referring to Figure 1 As shown in the drawings, the embodiments of the present application disclose a capacitor test lead-out tool, which mainly comprises a package shell 10, at least one shielded wire pin 20, at least one pair of test wire pins 30, at least one pair of test connecting posts 40, a ground wire 50 and at least one pair of test wires 60.
[0026] The package shell 10 is preferably in a cuboid structure, and at least one shielded wire pin 20 and at least one pair of test wire pins 30 are arranged on one side surface of the package shell 10, wherein the number of the test wire pins 30 is adapted to the number of the shielded wire pins 20, and one pair of test wire pins 30 comprises two test wire pins 30.
[0027] When specifically arranged, one shielded wire pin 20 and one pair of test wire pins 30 are usually arranged adjacently to facilitate the connection with two shielded wires led out from the two poles of the capacitor in the high-low temperature cycle box. In the present embodiment, four shielded wire pins and four pairs of test wire pins adapted thereto are arranged, and four capacitors can be connected simultaneously. Of course, the person skilled in the art can arrange the number of the shielded wire pins and the test wire pins adapted thereto according to the actual situation.
[0028] One end of each shielding wire pin 20 and each test wire pin 30 is located outside the package shell 10, and the other end is located inside the package shell 10, wherein the end of each shielding wire pin 20 is connected with one end of the ground wire 50 inside the package shell 10, and the end of each test wire pin 30 is connected with one end of the corresponding two test wires 60 inside the package shell 10. The other end of the ground wire 50 extends outside the package shell 10 after penetrating through the other side of the package shell 10, and the other end of the two test wires 60 extends outside the package shell 10 after penetrating through the other side of the package shell 10.
[0029] In addition, at least one pair of test connecting columns 40 is arranged on the package shell 10, and the number of test connecting columns 40 is matched with the number of test wire pins 30; wherein one end of each test connecting column 40 is connected with the corresponding test wire pin 30 inside the package shell 10, and the other end extends outside the package shell 10 after penetrating through the top side of the package shell 10.
[0030] When the capacitor test lead-out tool is used to lead out the two poles of the capacitor in the high-low temperature cycle box, a shielding wire is first connected to the two poles of each capacitor, and the shielding wire is an electric wire with shielding effect, wherein the inner core is used as the electrode, and the outer layer is the outer layer wire with shielding effect. When connecting, the inner cores of the two shielding wires are connected with a pair of test wire pins 30, and one test wire pin 30 can be arbitrarily selected for connection. After the outer layer wires of the two shielding wires are stripped off, they are twisted together to form a wire, and then they are connected with the shielding wire pin 20 after being insulated by a heat shrink tube.
[0031] When the inner core of the shielding wire of the two poles of the capacitor is connected with the test wire pin 30, a plug-and-play interface can be used to facilitate the connection process each time.
[0032] After the two poles of the multiple capacitors in the high-low temperature cycle box are led out, the temperature characteristic test of the capacitors can be continued by connecting the test meter probe with the test meter in a manual measurement manner, or other automatic methods can be used to test the test meter probe. When the manual measurement method is used, two test meter probes of the test meter are directly used to contact one pair of test connecting columns 40 on the package shell, the test connecting columns 40 are connected with the electrodes led out from both sides of the tested capacitor, and then the test button of the test meter is pressed to obtain the test data of the capacitor. By sequentially performing the operation, all the capacitors can be tested.
[0033] The capacitor test lead-out tool of the embodiment can lead out the two poles of multiple capacitors in the high-low temperature cycle box, so that the capacitors do not need to be taken out from the test environment each time, facilitates the connection of the test pen of the test machine, effectively improves the test efficiency, eliminates the safety hazards, effectively avoids the problem of serious influence on the test accuracy caused by the influence of the test environment temperature each time the capacitor is taken out, and is suitable for capacitor test of multiple specifications, sizes and varieties.
[0034] On the basis of the above embodiment, the capacitor test lead-out tool of the embodiment is preferably provided with a wiring device 70, which is provided with a ground wire terminal post 71 and at least one pair of test wire terminal posts 72. The ground wire terminal post 71 is connected with the ground wire 50, and the test wire terminal post 72 is connected with the test wire 60.
[0035] In actual application, the measurer can select multiple high-low temperature cycle boxes to measure the temperature characteristics of the capacitors according to the actual measurement situation. The shielding wires of the two poles of multiple capacitors in the same high-low temperature cycle box are led out through a capacitor test lead-out tool. The ground wire 50 of each capacitor test lead-out tool is connected with the ground wire terminal post 71 of the wiring device 70, and the two test wires 60 are respectively connected with a corresponding pair of test wire terminal posts 72.
[0036] In the embodiment, the wiring device is exemplarily provided with one ground wire terminal post and eight pairs of test wire terminal posts, which can be connected with eight high-low temperature cycle boxes at the same time.
[0037] On the basis of the above embodiment, the capacitor test lead-out tool of the embodiment is preferably provided with a converter 80, one end of which is respectively connected with the ground wire 50 and the test wire 60, and the other end is provided with a terminal connection wire 81.
[0038] When the capacitor test lead-out tool is not provided with the wiring device, the converter is directly connected with the ground wire and the test wire led out from the packaging shell. After the wiring device is provided, the converter is connected with the connection wires led out from the ground wire terminal posts and the test wire terminal posts of the wiring device.
[0039] After the two poles of the capacitor are led out by the capacitor test leading-out tool, other automatic modes can be used to test the connection with the test pen of the testing machine. The converter is preferably arranged in the embodiment, which mainly comprises a relay. The relay can be connected with the test pen of the testing machine. Meanwhile, the converter can be connected to a terminal through the terminal connection line thereof. The temperature curve consistent with the high-low temperature cycle box is set in the terminal. In addition, a thermocouple temperature gauge is arranged in the high-low temperature cycle box, which can measure the environment temperature in the high-low temperature cycle box in real time. The measured temperature is transmitted to the terminal in real time. Meanwhile, the high-low temperature cycle box and the testing machine are started. When the temperature reaches the testing time point, i.e. the temperature to be tested, the terminal sends an instruction to the converter, and the relay acts, so that the capacitances of the plurality of capacitors under different temperatures can be tested, and recorded in the terminal, thereby realizing automatic testing. Usually, three days of work is needed for manual measurement. Through the mode, the work can be completed in one day, and the work efficiency can be further improved.
[0040] The converter in the embodiment is directly purchased from the market, and a person skilled in the art can also make it according to actual needs. Of course, when the automatic measurement mode is used, the testing machine needs to use a digital bridge, which is connected with the terminal through an RS232 communication line, can receive the instruction of the terminal and feed back the corresponding measurement data to the terminal, thereby realizing automatic testing.
[0041] In summary, the capacitor test leading-out tool provided in the embodiment of the utility model can be conveniently connected with the test pen of the testing machine after the two poles of the capacitor in the high-low temperature cycle box are led out through two shielding lines, so that the capacitor does not need to be taken out from the testing environment every time, the operation is simple, the testing efficiency is effectively improved, the safety hidden danger is eliminated, the problem that the testing accuracy is seriously affected due to the influence of the temperature of the testing environment caused by taking out the capacitor every time is effectively avoided, and the capacitor test is suitable for capacitors of various specifications, sizes and varieties.
