[0002] When chargers and other products are tested before leaving the factory, they need to undergo insulation withstand voltage and performance tests. The insulation withstand voltage test is used to detect whether the insulation capacity of the tested product is qualified under transient high voltage. The performance test mainly tests the various performance indicators of the product to evaluate whether the product's performance meets the standards or user needs.

[0003] It should be noted that in order to ensure the accuracy and consistency of the test results, the insulation withstand voltage tester and the performance tester are connected to the same terminal of the product. When performing insulation withstand voltage test and performance test, the insulation withstand voltage tester needs to be connected to the terminal of the product. After the test is completed, the performance tester is manually connected to the terminal of the product.

[0004] In order to achieve the insulation withstand voltage test and performance test respectively after one connection, the previous test method is to achieve switching through a relay conversion circuit, such as the Chinese patent with publication number CN207799010U, which discloses a design circuit that can achieve lightning surge and insulation withstand voltage tests at the same time, adding a relay between the gas discharge tube and the chassis ground PE, and achieving switching between lightning surge and insulation withstand voltage tests by driving the contact action of the relay; however, once the relay fails, it will bring the risk of damaging the product or test equipment.

[0007] In order to achieve the above-mentioned objectives, the utility model proposes a switching device for insulation withstand voltage and performance testing, which includes a base and a probe row support frame arranged on the base, and a probe row base is also arranged between the two probe row support frames; an insulation withstand voltage female probe row is arranged on one side of the probe row base, and an insulation withstand voltage male probe row is also arranged on the probe row support frame opposite to the insulation withstand voltage female probe row; a performance test female probe row is arranged on the other side of the probe row base, and a performance test male probe row is also arranged on the probe row support frame opposite to the performance test female probe row; a shift assembly is arranged under the probe row base, and the shift assembly is used to drive the probe row base to perform reciprocating motion.

[0008] The beneficial effects of the utility model are:

[0018] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0019] The terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances. This is merely a way of distinguishing objects with the same attributes when describing the embodiments of the present application.

[0020] Example 1

[0021] This embodiment provides a specific implementation of a switching device for insulation withstand voltage and performance testing, as shown in the attached Figure 1 and 2 As shown;

[0022] The switching device for insulation withstand voltage and performance testing comprises a base 1 and a probe row support frame 2 arranged on the base 1, and a probe row base 6 is also arranged between the two probe row support frames 2;

[0023] An insulating and withstand voltage female probe row 8 is disposed on one side of the probe row base 6, and an insulating and withstand voltage male probe row 9 is also disposed on the probe row support frame 2 opposite to the insulating and withstand voltage female probe row 8;

[0024] A performance test female probe row 4 is disposed on the other side of the probe row base 6, and a performance test male probe row 3 is also disposed on the probe row support frame 2 opposite to the performance test female probe row 4;

[0025] A shift assembly is disposed below the probe row base 6 , and the shift assembly is used to drive the probe row base 6 to perform reciprocating motion.

[0026] In some embodiments, as shown in the attached Figure 1 To Attachment Figure 4As shown, the two probe row support frames 2 arranged on the base 1 have the same structure, both of which include a "concave" plate and a "triangular" reinforcement plate. The "concave" plate is vertically connected to the base 1, one side of the "triangular" reinforcement plate is connected to the base 1, and the other side of the "triangular" reinforcement plate is connected to the "concave" plate, thereby increasing the stability of the entire device.

[0027] As attached Figure 1 To Attachment Figure 4 As shown, the insulation withstand voltage male probe row 9 and the performance test male probe row 3 are respectively arranged on the corresponding probe row support frame 2, and the probes of the insulation withstand voltage male probe row 9 and the performance test male probe row 3 are in the grooves of the "concave" plate, making the entire device structure more compact.

[0028] It should be noted that during the insulation withstand voltage test, the wiring terminals of the insulation withstand voltage male probe row 9 are connected to the insulation withstand voltage test instrument; the shifting assembly drives the probe row base 6 to move forward until the insulation withstand voltage male probe row 9 is in good contact with the insulation withstand voltage female probe row 8. At this time, the performance test male probe row 3 and the performance test female probe row 4 are in a disconnected state, and the product can be subjected to an insulation withstand voltage test.

[0029] It should also be noted that during performance testing, the wiring terminals of the performance test male probe row 3 are connected to the performance testing instrument; the shifting assembly drives the probe row base 6 to move backward until the performance test male probe row 3 is in good contact with the performance test female probe row 4. At this time, the insulating withstand voltage male probe row 9 and the insulating withstand voltage female probe row 8 are in a disconnected state, and the product can be performance tested.

[0030] It should also be noted that the insulating voltage withstand female probe row 8 and the insulating voltage withstand male probe row 9 are a pair of mutually adaptable probe row combinations, and their specific structures and models are adapted to the wiring terminals of the insulating voltage withstand test instrument; the performance test female probe row 4 and the performance test male probe row 3 are also a pair of mutually adaptable probe row combinations, and their specific structures and models are adapted to the wiring terminals of the performance test instrument.

[0031] It should also be noted that the connection terminals of the insulation withstand voltage female probe row 8 and the performance test female probe row 4 are combined through the test line and connected to the terminals on the product.

[0032] In some embodiments, the displacement assembly is a slide cylinder 10, such as the HLSL series of AirTac or the MSDG of CKD. In other embodiments, the displacement assembly can also be other actuators that can drive the probe row base 6 to do reciprocating motion.

[0033] It should be noted that, in this embodiment, a cylinder is used to drive the probe row to move to achieve the switching between the insulation withstand voltage test and the performance test.

[0034] It can be understood that the slide cylinder 10 usually includes a cylinder body, a piston, a guide rod, a slide, etc. The slide is arranged below the probe row base 6 and connected to the probe row base 6. Air pressure is used to push the piston to achieve linear motion, thereby pushing the slide to reciprocate along the guide rod.

[0035] Example 2

[0036] Based on Example 1, this example provides another specific implementation of a switching device for insulation withstand voltage and performance testing.

[0037] In some embodiments, a magnetic switch is provided on the displacement assembly, and the magnetic switch is used to detect the position of the probe row base 6. Figure 3 and attached Figure 4 shown.

[0038] It should be noted that, in order to identify whether the cylinder of the slide cylinder 10 is working normally, two magnetic switches are installed on the cylinder, such as the first magnetic switch 11 and the second magnetic switch 12, to identify whether the cylinder has moved into position through the magnetic switch, and then detect the position of the probe row base 6; after the identification is in place, the product is tested accordingly, which plays a double protection role and is safer and more reliable to use;

[0039] It should also be noted that when the insulation withstand voltage male probe row 9 is in good contact with the insulation withstand voltage female probe row 8, the first magnetic switch 11 at the insulation withstand voltage end lights up; when the performance test male probe row 3 is in good contact with the performance test female probe row 4, the second magnetic switch 12 at the performance test end lights up.

[0040] Specifically, the first magnetic switch 11 and the second magnetic switch 12 can adopt DMSH-N-020 of AirTac, or other magnetic induction devices that can achieve the above functions.

[0041] In some embodiments, a speed regulating valve 7 is provided on the displacement assembly, and the speed regulating valve 7 is connected to the solenoid valve.

[0042] It should be noted that the air inlet of the slide cylinder 10 is also provided with a speed regulating valve 7 , and the speed regulating valve 7 is used to adjust the gas delivery speed of the slide cylinder 10 , and further adjust the moving speed of the probe row base 6 .

[0043] Specifically, the speed regulating valve 7 may be a throttle valve SL4, or other speed regulating valves 7 that can achieve the above functions.

[0044] Example 3

[0045] Based on the above embodiment, this embodiment provides another specific implementation of a switching device for insulation withstand voltage and performance testing.

[0046] As attached Figure 6 As shown, the probe installation positions on the insulating withstand voltage female probe row 8 and the performance test female probe row 4 are both provided with probe grooves.

[0047] It should be noted that the positions for installing probes on the insulating voltage withstand mother probe row 8 and the performance test mother probe row 4 are designed with probe slots, which can better isolate the probes from each other during testing, such as the performance test probe slot 401, the performance test probe 402, the insulating voltage withstand test probe slot 801 and the insulating voltage withstand test probe 802.

[0048] In some embodiments, guide posts 5 are provided on both the insulating withstand voltage female probe row 8 and the performance test female probe row 4 .

[0049] As attached Figure 5 As shown, two guide posts 5 are respectively provided on the insulating withstand voltage female probe row 8 and the performance test female probe row 4, which can also play a guiding role when docking with the male probe row.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
