In addition, a temperature control unit (not shown) may be disposed in the accommodating body 11 to simulate the operation conditions of the capacitor 200 at different temperatures. Each circuit board 300 is provided with at least a part of the capacitance elements 200, each detection connection portion 13 has a plurality of detection point groups 131, each of the detection point groups 131 corresponds to one of the capacitance elements 200, in this embodiment, each of the detection point groups 131 has four detection holes 131a, but in other implementation aspects, the number of the detection holes 131a of the detection point group 131 may be other numbers, which is not limited by the number of this embodiment, and in addition, the detection holes 131a of the detection point group 131 may be replaced by other connection structures, such as detection contact points, which is not limited by this embodiment. The probe connector 13 and the circuit board connector 12 can be electrically connected by the prior art, such as connectors, and the two connectors are connected by a conductor such as a wire or a flexible circuit board.

The detection device 2 comprises a moving means 21, and a detection module 22. The moving device 21 corresponds to the outer side setting surface 111 of the accommodating apparatus 1, and the moving device 21 includes a transverse slide rail 211 extending transversely, a vertical slide rail 212 extending vertically and being disposed on the transverse slide rail 211 in a transversely slidable manner, a sliding table 213 disposed on the vertical slide rail 212 in a vertically slidable manner, and a sliding seat 214 disposed on the sliding table 213 and being capable of moving toward the outer side setting surface 111 of the accommodating apparatus 1 or moving away from the outer side setting surface 111 of the accommodating apparatus 1 in a sliding manner. The detection module 22 includes a set of detectors 221 disposed on the sliding seat 214, and a detection instrument (not shown) connected to the set of detectors 221 through a line (not shown). In the embodiment, each of the probe groups 221 has four probe pins 221a, but in other implementation aspects, the number of the probe pins 221a may be other numbers, which is not limited by the number of the embodiment, and in addition, the probe pins 221a may be replaced by other connection structures, such as probe contact points, which is not limited by the embodiment.

By the cooperation of the transverse slide rails 211, the vertical slide rails 212 and the slide table 213, the slide block 214 can slide three-axially, so that the slide block 214 of the moving device 21 can be driven to slide to a position corresponding to any one of the detection point groups 131 of the detection connecting portion 13, so as to connect the detection point group 221 to any one of the detection point groups 131, and the detection instrument of the detection module 22 can detect the operation data of the capacitive element 200 after the connection is completed. Further, in the above-mentioned connection process, the vertical slide rail 212 slides laterally relative to the lateral slide rail 211 and the slide table 213 slides vertically relative to the vertical slide rail 212, so that the probe set 221 is aligned with the corresponding probe set 131, and then the slide base 214 slides relative to the slide table 213, so that the probe pins 221a of the probe set 221 are inserted into the probe holes 131a of the corresponding probe set 131, but not limited thereto. The number of cables between the accommodating device 1 and the detecting device 2 can be reduced by the moving device 21 of the detecting device 2, so as to reduce the condition that the electromagnetic interference generated by the cables distorts the operation data of the capacitance element 200. In addition, the matching relationship and the overall structure of the horizontal slide rail 211, the vertical slide rail 212 and the slide table 213 of the moving device 21 are only examples, and it can be understood that the matching relationship between the specific structure of the moving device 21 and the internal components can be changed and adjusted as required on the premise that the slide base 214 can slide to any one of the detection point groups 131 corresponding to the detection point group 131 of the detection connection portion 13, and the present embodiment should not be limited thereto. For example, the sliding between the lateral slide rail 211, the vertical slide rail 212, the sliding table 213 and the sliding seat 214 of the moving device 21 can be driven by a driving element such as a servo motor (not shown) or an air cylinder (not shown), but is not limited thereto.

It should be noted that each of the capacitance elements 200 and the corresponding circuit on the circuit board 300 form a circuit loop (not shown), the probe holes 131a of the corresponding probe point set 131 are respectively connected to four points on the circuit loop, and under different measurement requirements, when the probe set 221 is connected to any one of the probe point sets 131 in the probe point set 131, for example, only two probe pins 221a of the four probe pins 221a may be connected to the corresponding probe holes 131a, so that the probe set 221 is connected to two points of the four points. The circuit loop may be provided with a protection device (not shown) for example, the protection device being composed of a high-impedance resistor. When the capacitor element 200 or a subsequent circuit is short-circuited, most of the voltage drop falls on the protection device, and the current is limited by the high impedance characteristic of the protection device, the principle of the high impedance meter is similar to that of a high impedance meter on the market, and the high impedance meter obtains a small current through a resistor with high impedance, so that the resistance value of an object to be measured is measured. In addition, the protection device has no control mechanism in starting, and basically has functions after being arranged in the circuit loop.

Referring to fig. 1 and fig. 4 to 6, in addition, in the embodiment, the accommodating apparatus 1 further includes a plurality of first charging connection portions 14 located on the outer installation surface 111 and respectively electrically connected to the corresponding circuit board connection portions 12, and a plurality of pressing mechanisms 15 located on the outer installation surface 111 and respectively corresponding to the first charging connection portions 14. Each of the pressing mechanisms 15 includes two guiding posts 151 disposed on the outer side installation surface 111 and protruding in a direction away from the outer side installation surface 111, a pressing slider 152 slidably disposed on the two guiding posts 151, two installation posts 153 disposed on the outer side installation surface 111 and protruding in a direction away from the outer side installation surface 111, and a cam member 154 rotatably disposed on the two installation posts 153. The pressing slider 152 includes a body 152a disposed on the two guiding posts 151, a pressing circuit board 152b disposed on the body 152a facing the outer mounting surface 111, and two idle wheels 152c rotatably disposed on the body 152 a. The circuit board 152b has a second charging connecting portion 152d for contacting the first charging connecting portion 14, it should be noted that the first charging connecting portion 14 and the second charging connecting portion 152d each have a plurality of circuit contacts (not shown) arranged laterally, and the circuit board 152b is connected to a power supply unit (not shown) and is used for supplying power to the capacitor 200. Cam member 154 has two cam structures 154a at both ends corresponding to the two idler gears 152c, respectively, each of the cam structures 154a having a protrusion 154b, and two recesses 154c at both ends of the protrusion 154 b. In addition, an elastic element (not shown) may be connected between the body 152a of the pressing slider 152 and the outer disposing surface 111. It should be noted that, although in the present embodiment, each of the circuit board connecting portions 12 corresponds to only one first charging connecting portion 14 and one second charging connecting portion 152d of the pressing slider 152, in other implementation manners, the number of the corresponding first charging connecting portions 14 and the corresponding second charging connecting portions 152d of the pressing slider 152 may be more than two, which is not limited in the present embodiment.

The cam member 154 can be driven by a driving element such as a servo motor (not shown), when one recess 154c of the two recesses 154c receives the corresponding idler pulley 152c, the elastic element pushes the pressing slider 152 to separate the first charging connecting part 14 and the second charging connecting part 152d from each other, as shown in fig. 5; when the protrusions 154b are aligned with and push against the corresponding idlers 152c, the elastic member is pressed so that the first charging connection part 14 and the second charging connection part 152d are brought into contact with each other, as shown in fig. 6. The pressing slider 152 can be drivingly slid toward the outside installation surface 111 or away from the outside installation surface 111 by the cam member 154 of the pressing mechanism 15 to bring the first charging connecting portion 14 into contact with or separate from the second charging connecting portion 152 d. For example, when the cam member 154 of the pressing mechanism 15 rotates reciprocally, the first charging connecting portion 14 and the second charging connecting portion 152d can contact and separate intermittently, and the pressing mechanism 15 can also separate the first charging connecting portion 14 and the second charging connecting portion 152d from each other without charging the capacitor 200, so as to ensure the safety and the charging and discharging accuracy of the capacitor 200.

In summary, the capacitor life tester 100 of the present invention is configured to enable the sliding seat 214 to slide to the position corresponding to any one of the probing point groups 131 in the probing connection portion 13, so that the probing block group 221 disposed on the sliding seat 214 can be connected to any one of the probing point groups 131 in the probing point groups 131, thereby enabling the probing module 22 to probe the operation data of the capacitor 200, and this configuration can reduce the number of cables between the accommodating apparatus 1 and the probing apparatus 2, so as to reduce the situation that the operation data of the capacitor 200 is distorted due to the electromagnetic interference generated by the cables.
