[0035] Example

[0036] This embodiment provides a lightning protection product testing device, specifically a lightning protection device high voltage constant current source cycle testing device, which can be used for continuous batch sorting in the lightning protection product production process, and can also be used for laboratory testing of relevant parameters of lightning protection products. Among them, lightning protection products include varistors, semiconductor discharge tubes, gas discharge tubes, transient suppression diodes, power lightning arresters, signal lightning arresters, etc.

[0037] Please also read Figure 1 and Figure 2 In some embodiments, the lightning protection product testing equipment includes an electric control box 100 , a fixed mold 200 and a movable mold 300 .

[0038] Specifically, the fixed mold 200 is fixedly arranged on the electric control box 100. A positioning groove 210 is arranged on the fixed mold 200, and the positioning groove 210 is used to place the product to be tested.

[0039] The movable mold 300 is movably disposed on the electric control box 100. A probe group 310 is disposed on the movable mold 300, and the probe group 310 includes a plurality of probes 311. Each probe 311 is electrically connected to the electric control box 100, and each probe 311 contacts the product to be tested in the positioning groove 210 when the movable mold 300 is located at one end of the moving stroke, and separates from the product to be tested in the positioning groove 210 when the movable mold 300 is located at the other end of the moving stroke.

[0040] When testing a lightning protection product, the tester can place the product to be tested in the positioning groove 210 on the fixed mold 200, position the product to be tested, and then control the movable mold 300 to move toward the fixed mold 200. When the movable mold 300 moves to one end of the moving stroke, the multiple probes 311 provided on the movable mold 300 contact the product to be tested in the positioning groove 210. Subsequently, the electric control box 100 applies a certain voltage or current to the product to be tested through the probes 311, and the test of the product to be tested can be completed. Therefore, by using the above-mentioned lightning protection product testing equipment, the tester can quickly and accurately make multiple probes 311 contact the product to be tested at the same time, which is easy to operate and more efficient.

[0041] Exemplarily, when testing a clamp-type lightning protection product, the DC breakdown voltage of the product to be tested is first estimated according to the model of the product to be tested, and then the initial test voltage is set at 150% of the estimated voltage.

[0042] Alternatively, when testing switch-type lightning protection products, set the test voltage according to the upper and lower voltage limits of the product to be tested.

[0043] In some embodiments, at least two probe groups 310 are provided, each probe group 310 includes four probes 311 , and the positioning grooves 210 are used to place the same number of products to be tested as the probe groups 310 .

[0044] At this point, testers can test multiple products to be tested at one time, further improving testing efficiency.

[0045] For example, the number of probe groups 310 is five, and the product to be tested is set as a five-joint plate. The tester first places the five-joint plate in the positioning groove 210, and then controls the movable mold 300 to move toward the fixed mold 200, so that the five groups of probes 311 on the movable mold 300 are respectively in contact with the corresponding products to be tested, and the five products to be tested are tested at the same time.

[0046] In some embodiments, the lightning protection product testing device further includes a bracket 400. The bracket 400 is fixedly disposed on the electric control box 100, and a driving member 410 is disposed on the bracket 400. The driving end of the driving member 410 is connected to the movable mold 300 to drive the movable mold 300 to move in a direction close to or away from the fixed mold 200.

[0047] Exemplarily, the bracket 400 and the fixed mold 200 are both fixedly disposed on the top surface of the electric control box 100 , the positioning groove 210 is disposed on the upper surface of the fixed mold 200 , and the movable mold 300 is located above the fixed mold 200 .

[0048] The bracket 400 is composed of two side panels 401 and a panel 402. The two side panels 401 are vertically arranged, and the bottom ends of the side panels 401 are fixedly connected to the electric control box 100. The panel 402 is located between the two side panels 401 and is connected to the tops of the two side panels 401 respectively.

[0049] Accordingly, the driving member 410 is a cylinder, the cylinder body of which is fixedly arranged on the panel 402, and the piston rod of which extends vertically downward and is connected to the movable mold 300 to drive the movable mold 300 to descend or ascend.

[0050] When the movable mold 300 descends to one end of the moving stroke, the probe 311 on the movable mold 300 contacts the product to be tested in the positioning groove 210. When the movable mold 300 rises to the other end of the moving stroke, the probe 311 on the movable mold 300 separates from the product to be tested in the positioning groove 210.

[0051] Furthermore, the lightning protection product testing equipment further includes a guide rod 500. The guide rod 500 is arranged along the moving direction of the movable mold 300, and the guide rod 500 is fixedly connected to one of the movable mold 300 and the electric control box 100, and the guide rod 500 is slidably matched with the other of the movable mold 300 and the electric control box 100.

[0052] During the movement of the movable mold 300 , the guide rod 500 limits and guides the movable mold 300 to ensure that when the movable mold 300 moves to one end of the moving stroke, the probe 311 on the movable mold 300 is accurately aligned with the product to be tested in the positioning groove 210 .

[0053] Exemplarily, the guide rod 500 is vertically arranged. The bottom end of the guide rod 500 is fixedly connected to the electric control box 100 , and the guide rod 500 is slidably arranged on the movable mold 300 .

[0054] Please also read Figure 3 and Figure 4 In some embodiments, the positioning groove 210 has a first side wall 211, a second side wall 212 and a third side wall 213. The first side wall 211 is disposed opposite to the second side wall 212, and the third side wall 213 connects the first side wall 211 and the second side wall 212 respectively.

[0055] After the tester places the product to be tested in the positioning groove 210 , the product to be tested contacts the first side wall 211 , the second side wall 212 and the third side wall 213 at the same time, and the first side wall 211 , the second side wall 212 and the third side wall 213 are used to position the product to be tested.

[0056] Specifically, the first side wall 211 and the second side wall 212 are parallel to each other, the third side wall 213 is perpendicular to the first side wall 211 and the second side wall 212 , and the product to be tested is a rectangular PCB board.

[0057] Furthermore, a first limiting pin 220 is provided on the fixed mold 200, and the first limiting pin 220 is located in the positioning groove 210. When the product to be tested is placed in the positioning groove 210, the first limiting pin 220 contacts the side of the product to be tested away from the third side wall 213, and cooperates with the first side wall 211, the second side wall 212 and the third side wall 213 to fully limit the product to be tested, so as to prevent the product to be tested from moving during the test process.

[0058] Specifically, the number of the first limiting pins 220 is two, and the two first limiting pins 220 are arranged in a direction parallel to the third side wall 213 .

[0059] Furthermore, a guide surface 214 is provided at the slot opening of the positioning slot 210 .

[0060] When the tester places the product to be tested into the positioning groove 210 , the guide surface 214 can guide the product to be tested and align the product to be tested with the positioning groove 210 , so that the product to be tested can be smoothly placed into the positioning groove 210 .

[0061] Specifically, the notch of the positioning groove 210 is chamfered to form the guide surface 214. The guide surface 214 can be an inclined surface or an arc surface, which is not limited in this embodiment.

[0062] In some embodiments, the fixed mold 200 is provided with a support step 230 and / or a support pin 240 . The support step 230 is provided on the side wall of the positioning groove 210 , and the support pin 240 is located in the positioning groove 210 .

[0063] Specifically, the fixed mold 200 is provided with a support step 230 and a support pin 240. The support step 230 is provided on the third side wall 213 to support the area of ​​the product to be tested close to the third side wall 213. The support pin 240 is used to support the middle part of the product to be tested and the area of ​​the product to be tested away from the third side wall 213.

[0064] Alternatively, only the support step 230 may be provided on the fixed mold 200. In this case, the support step 230 is respectively provided on the first side wall 211, the second side wall 212 and the third side wall 213 to support the periphery of the product to be tested.

[0065] Alternatively, only the supporting pins 240 may be provided on the fixed mold 200 , and the supporting pins 240 are evenly distributed in the positioning grooves 210 .

[0066] See also Figure 5 In some embodiments, a mounting hole 320 is provided on the movable mold 300. The probe 311 is inserted into the mounting hole 320 and has an interference fit with the hole wall of the mounting hole 320.

[0067] In the lightning protection product testing equipment, the probe 311 is a consumable part. A mounting hole 320 is provided on the movable mold 300 for the probe 311 to pass through, and the probe 311 is interference-fitted with the hole wall of the mounting hole 320, and the probe 311 is fixed by friction, so that the tester can quickly replace the probe 311 when the probe 311 is damaged.

[0068] Please refer again Figure 2 Furthermore, a second limiting pin 330 is provided on the movable mold 300, and the second limiting pin 330 abuts against the product to be tested in the positioning groove 210 when the movable mold 300 is located at one end of the moving stroke.

[0069] Specifically, the second limit pin 330 is disposed on the lower surface of the movable mold 300. When the movable mold 300 is lowered until the second limit pin 330 abuts against the product to be tested in the positioning groove 210, the movable mold 300 is located at one end of the moving stroke, and the probe 311 just contacts the product to be tested. Therefore, the second limit pin 330 can prevent the probe 311 from being over-pressed and flattening the product to be tested, making the probe 311 less likely to be damaged, and at the same time avoiding damage to the product to be tested before the test is completed.

[0070] In summary, when the tester uses the above-mentioned lightning protection product testing equipment to test the lightning protection product, the product to be tested can be placed in the positioning groove 210 on the fixed mold 200, the product to be tested can be positioned, and then the movable mold 300 can be controlled to move toward the fixed mold 200. When the movable mold 300 moves to one end of the moving stroke, the multiple probes 311 arranged on the movable mold 300 contact the product to be tested in the positioning groove 210. Subsequently, the electric control box 100 applies a certain voltage or current to the product to be tested through the probes 311, and the test of the product to be tested can be completed, which is easy to operate and more efficient.

[0071] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0072] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0073] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
