Description

Technical Field

[0001] This utility model relates to the technical field of capacitor testing devices, and in particular to a capacitor charging and discharging detection device. Background Technology

[0002] Currently, the most important parameters in capacitor production are the stability of capacitance and loss. For small capacitors with simple and consistent shapes, multiple continuous automatic short-circuit charging and discharging devices are generally used.

[0003] Existing continuous automatic short-circuit charge / discharge devices include a detector and a testing device functionally connected to the detector. The testing device includes a substrate and a first vertical plate and a second vertical plate disposed opposite each other on the substrate. The top of the first vertical plate has a plurality of first test terminals, and the top of the second vertical plate also has second test terminals corresponding one-to-one with the first test terminals. During testing, the two leads of a capacitor are placed on the first and second test terminals respectively, thereby completing the capacitor charge / discharge test. Since the distance between the first and second vertical plates is fixed, and the two leads of the capacitor are of different sizes, this obviously cannot meet the charging / discharging requirements of capacitors with different lead sizes.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content

[0039] Example:

[0040] Please refer to Figure 1-6This application discloses a capacitor charging and discharging detection device, comprising a housing 10, a detector 100 disposed within the housing 10, the detector having a charging and discharging time setting module, a charging and discharging number setting module, a start button, and a power switch, a capacitor testing device 200 functionally connected to the detector 100, the capacitor testing device 200 being electrically connected to the charging and discharging time setting module, the charging and discharging number setting module, the start button, and the power switch, and three capacitor core testing devices 300 functionally connected to the detector 100, the capacitor core testing devices 300 being electrically connected to the charging and discharging time setting module, the charging and discharging number setting module, the start button, and the power switch, respectively; the capacitor testing devices 200 are arranged in parallel. There is a first pin insertion hole 205 and a second pin insertion hole 206. The first pin insertion hole 205 and the second pin insertion hole 206 are elongated holes. The distance between the first pin insertion hole 205 and the second pin insertion hole 206 is greater than or equal to five millimeters. The distance between the end of the first pin insertion hole 205 away from the second pin insertion hole 206 and the end of the second pin insertion hole 206 away from the first pin insertion hole 205 is less than or equal to fifty millimeters. Through the above structural design, the two pins of capacitors with different pin sizes can be inserted into the first pin insertion hole 205 and the second pin insertion hole 206 respectively to realize the charging and discharging operation of the capacitor, thereby meeting the charging and discharging operation requirements of capacitors with different pin sizes.

[0041] Specifically, the box body 10 includes a bottom box 11 and a lid 12 that covers the bottom box 11 and is hinged to the bottom box 11, which allows users to open and close the box body 10 more easily. At the same time, the combination of the bottom lid 11 and the lid 12 can provide better sealing and prevent external factors such as dust and moisture from damaging the contents of the box.

[0042] Specifically, the capacitance testing device 200 has a positive terminal 201 and a negative terminal 202, which are respectively connected to the positive terminal and the negative terminal of the detector.

[0043] Specifically, the capacitance testing device 200 is provided with a first mounting hole 203 and a second mounting hole 204. Two opposing first spring contacts 207 are installed in the first mounting hole 203, forming a first pin insertion hole 205 between the two first spring contacts 207. Two opposing second spring contacts 208 are installed in the second mounting hole 204, forming a second pin insertion hole 206 between the two second spring contacts 208. The first spring contact 207 includes a first fixing member 2071 and a first R-shaped spring contact 2072 integrally formed with the first fixing member 2071. The second spring contact 208 includes a second fixing member 2081 and a second R-shaped spring contact 2072 integrally formed with the second fixing member 2071. A second R-shaped spring 2082 is integrally formed from a fixing component 2081. Both the first fixing component 2071 and the second fixing component 2081 are provided with mounting holes and are respectively installed on the inner walls of the first mounting hole 203 and the second mounting hole 204. The gap distance between the two first R-shaped springs 2072 and the gap distance between the two second R-shaped springs 2082 are both smaller than the diameter of the capacitor leads. Therefore, when the two leads of the capacitor are respectively inserted into the first lead insertion hole 205 and the second lead insertion hole 206, the two first R-shaped springs 2072 and the two second R-shaped springs 2082 respectively form a clamping shape for the two leads of the capacitor, which is simple and reliable.
