Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of PogoPin processing devices, and particularly relates to a split-type PogoPin rapid serial connection testing device. Background Technology
[0002] In the current PogoPin manufacturing industry, there is a need to test the contact conductivity, power-on lifespan, average resistance, and destructive limit lifespan under high current for split-type PogoPin products. Due to the small size of PogoPin products, conventional clamping fixtures cannot position them or perform power-on / off functions. Therefore, each test involves loading the product into a custom-designed host with integrated circuitry. Limited by host cost and quantity, only a few products can be tested at a time (typically 4-8). Because of the small sample size, the test results often do not accurately reflect the actual production ratio when products exhibit abnormalities. To increase the sample size, multiple batches of 4-8 products are required, wasting significant testing time and making the consistency of results susceptible to fluctuations. For example, each batch test typically takes 96-144 hours; with multiple batches, the duration can reach half a month to a month, due to numerous variables causing fluctuations. This situation in existing technology results in long development cycles, high labor costs, and high material costs for R&D investment in split-type PogoPin products. Utility Model Content
[0003] The purpose of this invention is to provide a split-type PogoPin rapid series testing device, which aims to solve the technical problems of long development cycles, high labor costs, and high R&D investment caused by the inability of existing split-type PogoPin products to quickly conduct batch testing of product electrical performance.
[0004] To achieve the above objectives, this utility model provides a split-type PogoPin rapid tandem testing device, comprising:
[0005] The upper fixture includes an upper fixed plate, a positioning pin, and multiple upper conductive blocks. The positioning pin is fixed to the bottom of the upper fixed plate near its edge, and the upper conductive blocks are spaced apart and connected and fixed to the bottom of the upper fixed plate.
[0006] The lower fixture includes a lower fixed plate, a height limiting block, and multiple lower conductive blocks. The lower fixed plate has a positioning hole and a height limiting block that match the positioning pin near its edge on the top. The lower conductive blocks are spaced apart and connected and fixed to the top of the lower fixed plate. Each lower conductive block has a PogoPin positioning hole near its two ends to ensure that the PogoPin product stands upright.
[0007] When the upper tooling and the lower tooling are closed, the positioning pin is inserted into the positioning hole, and the two ends of the orthographic projection of each upper conductive block fall on the two adjacent lower conductive blocks and cover the PogoPin positioning holes on the two adjacent lower conductive blocks.
[0008] Optionally, the bottom of the upper fixing plate is provided with a plurality of upper conductive block holes, each of the upper conductive block holes being embedded in the upper conductive block hole, and each of the upper conductive blocks being flush with the bottom surface of the upper fixing plate.
[0009] Optionally, the top of the lower fixing plate is provided with a plurality of lower conductive block holes, each of the lower conductive blocks is embedded in the respective lower conductive block holes, and each of the lower conductive blocks is flush with the top surface of the lower fixing plate.
[0010] Optionally, the lower tooling further includes two terminals, which are electrically connected to the two lower conductive blocks located at the beginning and end of the series circuit, respectively.
[0011] Optionally, the terminal block is locked to the lower fixing plate by a conductive screw and abuts against the surface of the corresponding lower conductive block.
[0012] Optionally, both terminals are connected to conductive cables.
[0013] Optionally, the height limiting block is detachably locked to the lower fixing plate by fastening screws.
[0014] The above-mentioned one or more technical solutions in the split-type PogoPin rapid series testing device provided in this utility model embodiment have at least one of the following technical effects: In the first step, the PogoPin product is positioned into the PogoPin positioning hole of the lower conductive block using an aligning machine or manually, and the product positioning status and consistency are checked. At this time, the PogoPin product and the lower conductive block achieve electrical contact. In the second step, the upper fixing plate and the lower fixing plate are molded together using the cooperation of the positioning pin and the positioning hole. At this time, the upper conductive block presses against the PogoPin product, achieving electrical contact with the PogoPin product. Due to the orthographic projection of each upper conductive block... The two ends fall onto two adjacent lower conductive blocks and cover the PogoPin positioning holes on the two adjacent lower conductive blocks. In this way, each sequentially arranged lower conductive block can be electrically connected to an upper conductive block through a PogoPin product, and then electrically connected to another adjacent PogoPin product through the upper conductive block, and then electrically connected to another adjacent lower conductive block through the PogoPin product. This achieves the connection of the lower conductive block at the beginning to the lower conductive block at the end through the PogoPin product and the upper conductive block. In the third step, the corresponding experimental equipment is connected to the two lower conductive blocks at the beginning and end of the series circuit to start the testing operation. In this way, the efficiency of the testing operation is improved, the development time is reduced, the material cost of R&D is reduced, and the sampling accuracy is improved.

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.
[0032] In one embodiment of this utility model, such as Figure 1 , 4 As shown in Figure 5, a split-type PogoPin rapid serial connection test device is provided, including an upper fixture 10 and a lower fixture 20, which can realize mold closing.
[0033] like Figures 4-5 As shown, the upper fixture 10 includes an upper fixed plate 11, positioning pins 12, and multiple upper conductive blocks 13. The positioning pins 12 are fixed to the bottom of the upper fixed plate 11 near its edge. The upper conductive blocks 13 are spaced apart and connected to the bottom of the upper fixed plate 11. The positioning pins 12 are used for positioning during the mold closing process with the lower fixed plate 21 and are made of stainless steel. The upper conductive blocks 13 are used to connect and conduct PogoPin products 100 after mold closing. The upper conductive blocks 13 are made of brass with a gold-plated surface to improve oxidation resistance and reduce contact resistance. Each conductive block connects 2 PogoPin products 100. The upper fixed plate 11 is used to install and fix the positioning pins 12 and the upper conductive blocks 13.
[0034] like Figures 4-5 As shown, the lower fixture 20 includes a lower fixed plate 21, a height limiting block 22, and multiple lower conductive blocks 23. The lower fixed plate 21 has a positioning hole 212 near its edge on its top, which matches the positioning pin 12, and a height limiting block 22. The lower conductive blocks 23 are spaced apart and connected to the top of the lower fixed plate 21. Each lower conductive block 23 has a PogoPin positioning hole 231 near both ends to ensure the PogoPin product stands upright. The height limiting block 22 limits the height of the upper fixed plate 11 and the lower fixed plate 21 when they are closed, maintaining the PogoPin product 100 at a reasonable working height during testing to prevent damage. The lower conductive block 23 is used to connect the PogoPin product 100. The lower conductive block 23 is made of brass with gold plating to improve oxidation resistance and reduce contact resistance. Each lower conductive block 23 is used for positioning the PogoPin product 100. Each lower conductive block 23 connects 2 PogoPin products 100 and they are staggered to form a series connection.
[0035] When the upper tooling 10 and the lower tooling 20 are closed, the positioning pin 12 is inserted into the positioning hole 212, and the two ends of the orthographic projection of each upper conductive block 13 fall on the two adjacent lower conductive blocks 23, and cover the PogoPin positioning hole 231 on the two adjacent lower conductive blocks 23.
[0036] The following describes in detail the working process of the split-type PogoPin rapid series testing device provided in this embodiment of the present invention: First, the PogoPin product 100 is positioned into the PogoPin positioning hole 231 of the lower conductive block 23 using an alignment machine or manually, and the product positioning status and consistency are checked. At this time, the PogoPin product 100 and the lower conductive block 23 achieve electrical contact. Second, using the cooperation of the positioning pin 12 and the positioning hole 212, the upper fixing plate 11 and the lower fixing plate 21 are molded together. At this time, the upper conductive block 13 presses against the PogoPin product 100, achieving electrical contact with the PogoPin product 100. Since the two ends of the orthographic projection of each upper conductive block 13 fall on the adjacent... Two lower conductive blocks 23 are provided, covering the PogoPin positioning holes 231 on adjacent lower conductive blocks 23. Each sequentially arranged lower conductive block 23 can be electrically connected to an upper conductive block 13 via a PogoPin product 100, and then electrically connected to another adjacent PogoPin product 100 via the upper conductive block 13, and then electrically connected to another adjacent lower conductive block 23 via the PogoPin product 100. This connects the first lower conductive block 23 in series with the upper conductive block 13 via the PogoPin product 100 and the lower conductive block 13 to the last lower conductive block 23. In the third step, the corresponding experimental equipment is connected to the two lower conductive blocks 23 at the beginning and end of the series circuit to begin testing. This improves the efficiency of testing, reduces development time, lowers material costs in R&D, and increases sampling accuracy.
[0037] In one embodiment of this utility model, such as Figure 4 As shown, the bottom of the upper fixing plate 11 is provided with a plurality of upper conductive block holes 111, and each upper conductive block 11 is embedded in the respective upper conductive block hole 111, and each upper conductive block 13 is flush with the bottom surface of the upper fixing plate 11. Specifically, the embedded method can ensure an interference fit between the upper conductive block 13 and the upper conductive block hole 111, which is stable and reliable. Furthermore, being flush with the bottom surface of the upper fixing plate 11 can avoid interference with other components due to steps, thereby ensuring more reliable operation.
[0038] In one embodiment of this utility model, such as Figure 3As shown, the top of the lower fixing plate 21 is provided with a plurality of lower conductive block holes 211, each of which is embedded in the other of the lower conductive block holes 211, and each lower conductive block 23 is flush with the top surface of the lower fixing plate 21. Specifically, the embedded method ensures an interference fit between the lower conductive block 23 and the lower conductive block hole 211, ensuring stability and reliability. Furthermore, being flush with the top surface of the lower fixing plate 21 avoids interference with other components due to steps, thereby ensuring more reliable operation.
[0039] In one embodiment of this utility model, such as Figure 1 , 3 As shown in Figure 5, the lower fixture 20 also includes two terminals 24, which are electrically connected to the two lower conductive blocks 23 located at the beginning and end of the series circuit, respectively. The terminals 24 are designed to facilitate wiring and energizing tests using them as positive and negative terminals.
[0040] In one embodiment of this utility model, such as Figure 3 , 5 As shown, the terminal 24 is locked to the lower fixing plate 21 by conductive screws 241 and abuts against the surface of the corresponding lower conductive block 23. Specifically, the conductive screws 241 enable the two terminal 24 to be detachably installed and removed, facilitating inspection and maintenance.
[0041] In one embodiment of this utility model, such as Figure 5 As shown, both terminals 24 are connected to conductive cables 25. The conductive cables 25 can be directly connected to powered equipment, which is convenient and practical.
[0042] In one embodiment of this utility model, such as Figures 2-5 As shown, the height limiting block 22 is detachably locked to the lower fixing plate 21 by fastening screws 221. Specifically, the height limiting block 22 is detachably connected to the lower fixing plate 21 by fastening screws 221, which facilitates the replacement of height limiting blocks 22 of different heights when testing PogoPin products 100 of different heights.
[0043] The split-type PogoPin rapid serial testing device provided in this embodiment solves the bottleneck of PogoPin products 100 being unable to be tested in batches; moreover, the testing device is universal and can be applied to products with similar structures, without the need for customized testing host or motherboard.
[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
