Description

Technical Field

[0001] This utility model belongs to the technical field of PogoPin processing devices, and particularly relates to an integrated PogoPin rapid serial testing device. Background Technology

[0002] In the current PogoPin product manufacturing industry, when testing the contact conductivity, power-on lifespan, and average resistance of integrated PogoPin products, it is necessary to address the structural characteristics of integrated PogoPin products, where the head and tail move simultaneously during use. Therefore, it is usually necessary to solder wire to the tail of the PogoPin product, utilizing the flexibility of the wire to allow for sufficient movement space during product compression.

[0003] However, due to the product's small size, even after soldering wires to the rear, it still cannot be assembled in series. Therefore, each test still requires mounting the product onto a custom motherboard or mainframe with integrated circuitry. Limited by the cost and quantity of the mainframe, only a few products can be tested at a time (generally around 4 to 8). Because of the small sample size, when products malfunction, the test results often do not accurately reflect the true production ratio. To increase the sample size, multiple batches of testing (4 to 8 units per batch) are required, wasting significant testing time, and the consistency of the results is easily affected by fluctuations. (Each batch test typically takes 96 to 144 hours; with multiple batches, the duration can be as long as half a month to a month, due to numerous variables causing fluctuations).

[0004] This situation with existing technologies results in long development cycles, high labor costs, and high material costs for R&D investment. Utility Model Content

[0005] The purpose of this invention is to provide an integrated 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 integrated PogoPin products to quickly test the electrical performance of products in batches.

[0006] To achieve the above objectives, this utility model provides an integrated PogoPin rapid serial testing device, comprising an upper fixing plate, a product positioning plate, a lower fixing plate, multiple conductive blocks, and multiple test probes. The conductive blocks are spaced apart and fixed to the bottom of the upper fixing plate. The lower fixing block has multiple spaced recessed positioning holes, each containing one test probe. Two adjacent test probes form a group, and their bottoms are connected via a power harness. The product positioning plate is positioned between the lower and upper fixing plates and has product positioning holes corresponding to the positions of the recessed positioning holes. These product positioning holes are used to place the PogoPin product to be tested. Each conductive block's orthographic projection covers two product positioning holes, and the test probes in the two recessed positioning holes below the two product positioning holes covered by the orthographic projection of one conductive block are not connected by the power harness.

[0007] Optionally, the bottom of the upper fixing plate is provided with a plurality of conductive block holes, each of the conductive blocks being embedded in the respective conductive block holes, and each of the conductive blocks being flush with the bottom surface of the upper fixing plate.

[0008] Optionally, the bottom of the lower fixing plate is provided with a plurality of wire bonding clearance grooves for accommodating each of the power cable harnesses.

[0009] Optionally, it also includes two conductive cables, which are electrically connected to the two test probes located at the beginning and end of the series circuit, respectively.

[0010] Optionally, the product positioning plate is provided with an upper positioning hole and a middle positioning hole near its edge, the lower fixing plate is provided with a lower positioning hole corresponding to the upper positioning hole, the upper fixing plate is connected with an upper positioning pin for insertion into the upper positioning hole and the lower positioning hole, and the lower fixing plate is connected with a lower positioning pin for insertion into the middle positioning hole.

[0011] Optionally, the test probe includes a test needle, a test needle tube, a fastening ring, and a spring. The outer periphery of the test needle has a needle outer ring, the top of the test needle tube has a needle tube outer ring, and the bottom of the test needle tube has a needle tube inner ring. The spring is sleeved outside the test needle, the test needle passes through the test needle tube, the upper end of the spring abuts against the needle outer ring, and the lower end of the spring abuts against the needle tube inner ring. The fastening ring is interference-fitted onto the outer periphery of the test needle as it passes through the test needle tube. When the test probe is placed in the countersunk limiting hole, the step of the countersunk limiting hole supports the needle tube outer ring.

[0012] The integrated PogoPin rapid tandem testing device provided in this utility model embodiment has at least one of the following technical effects: In use, the PogoPin product is positioned into the positioning hole of the product positioning plate using a aligner or manually, and the positioning status and consistency of the PogoPin product are checked. Next, the product positioning plate with the PogoPin product is molded with the lower fixing plate. After molding, the PogoPin product does not contact the dedicated test probe in the recessed platform of the lower fixing plate, preventing the PogoPin product from being ejected, and ensuring stable positioning. Then, the upper fixing plate is placed over the product positioning block. Due to the free elasticity of the PogoPin product, the upper fixing plate after molding is in a floating state, lifted by the PogoPin product. Finally, the molded test module is placed into the pressing device, and the pressing device is operated to press down, using the downward pressure to mold the test module. After molding, the test module is fixed, and the product is positioned at a uniform working height due to height limitations. The corresponding experimental equipment is connected to the positive and negative cables, and the testing operation begins, repeating the cycle. This improves the efficiency of testing operations, reduces development time, lowers material costs in R&D, and increases sampling accuracy. Attached Figure Description

[0029] The embodiments of this utility model are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description is based on the accompanying drawings. Figures 1-6 The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0030] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. 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.

[0033] In one embodiment of this utility model, such as Figures 1-5 As shown, an integrated PogoPin rapid serial connection test device is provided, including an upper fixing plate 10, a product positioning plate 20, a lower fixing plate 30, multiple conductive blocks 40, and multiple test probes 50. Each conductive block 40 is spaced apart and connected and fixed to the bottom of the upper fixing plate 10. The lower fixing plate has multiple spaced recessed limiting holes 31, each containing one test probe 50. Two adjacent test probes 50 form a group, and their bottoms are connected via a power cable harness 60. The product positioning plate... The product positioning plate 20 is located between the lower fixing plate 30 and the upper fixing plate 10. The product positioning plate 20 is provided with product positioning holes 21 that correspond one-to-one with the positions of each of the sinking limit holes 31. The product positioning holes 21 are used to place the PogoPin product 100 to be tested. The orthographic projection of each conductive block 40 covers two of the product positioning holes 21, and the test probes 50 in the two sinking limit holes 31 below the two product positioning holes 21 covered by the orthographic projection of one conductive block 40 are not connected by the power harness 60. It should be noted that the above-mentioned "not connected by the power harness 60" refers to the situation before mold closing. For example, if there are test probes 50 at the first position, the second position, the third position, and the fourth position in sequence, then the test probes 50 at the first and second positions are connected by the power harness 60, and the test probes 50 at the third and fourth positions are also connected by the power harness 60. At this time, the test probes 50 at the second and third positions are not connected by the power harness 60. After mold closing, all test probes 50 are connected in series through the power harness 60 and the conductive block 40.

[0034] When using the integrated PogoPin rapid serial testing device provided in this embodiment of the invention, the PogoPin product 100 is positioned into the positioning hole of the product positioning plate 20 using an alignment machine or manually, and the positioning status and consistency of the PogoPin product 100 are checked. Next, the product positioning plate 20 with the PogoPin product 100 installed is closed with the lower fixing plate 30. After the mold is closed, the PogoPin product 100 does not contact the dedicated test probe in the sinking platform in the lower fixing plate 30, so the PogoPin product 100 will not be pushed out, and the positioning status is stable. Then, the upper fixing plate 10 is placed on the product positioning block. At this time, due to the free elasticity of the PogoPin product 100, the upper fixing plate 10 after the mold is closed is in a floating state that is lifted by the PogoPin product 100. Finally, the molded test module is placed into the pressing equipment, and the pressing equipment is operated to press down, and the test module is molded by the downward pressure of the equipment. After the mold is closed, the test module is fixed. Due to the height restriction, the product is located at a uniform working height. The corresponding experimental equipment is connected to the positive and negative cables to start the test operation, and the cycle is repeated.

[0035] The integrated PogoPin rapid serial testing device provided in this embodiment solves the bottleneck of batch testing of integrated PogoPin spring-loaded products. The testing device is universal and applicable to products with similar structures, eliminating the need for customized testing hosts or motherboards. This improves testing efficiency, reduces development time, lowers R&D material costs, and increases sampling accuracy.

[0036] In one embodiment of this utility model, such as Figure 4 As shown, the bottom of the upper fixing plate 10 is provided with a plurality of conductive block holes 11, and each conductive block 40 is respectively embedded in the conductive block hole 11, and each conductive block 40 is flush with the bottom surface of the upper fixing plate 10. Specifically, the embedded method can ensure that the conductive block 40 and the conductive block hole 11 have an interference fit, which is stable and reliable. Furthermore, being flush with the bottom surface of the upper fixing plate 10 can avoid interference with other components due to the presence of steps, thereby ensuring more reliable operation.

[0037] In one embodiment of this utility model, such as Figure 2 and 4 As shown, the bottom of the lower fixing plate 30 is provided with a plurality of wire bonding relief grooves 32 for accommodating each of the power cable harnesses 60. Specifically, the wire bonding relief grooves 32 are provided to accommodate the power cable harnesses 60, ensuring that the two test probes 50 can be soldered in series. Furthermore, the power cable harnesses 60 connected between the two test probes 50 will not be exposed below the lower fixing plate 30, thus not affecting the normal placement of the lower fixing plate 30 on the plane.

[0038] In one embodiment of this utility model, such as Figure 2 and 4 As shown in Figure 5, the integrated PogoPin rapid series testing device also includes two conductive cables 70, which are electrically connected to the two test probes 50 located at the beginning and end of the series circuit, respectively. Specifically, the conductive cables 70 can be directly connected to the powered equipment, which is convenient and practical.

[0039] In one embodiment of this utility model, such as Figure 1 and 3 As shown in Figure 4, the product positioning plate 20 has an upper positioning hole 22 and a middle positioning hole 23 near its edge. The lower fixing plate 30 has a lower positioning hole 33 corresponding to the upper positioning hole 22. The upper fixing plate 10 is connected to an upper positioning pin 12 for insertion into the upper positioning hole 22 and the lower positioning hole 33, and the lower fixing plate 30 is connected to a lower positioning pin 34 for insertion into the middle positioning hole 23. Specifically, during mold closing, the upper fixing plate 10 is inserted into the upper positioning hole 22 and the lower positioning hole 33 through the upper positioning pin 12, and the lower fixing plate 30 is inserted into the middle positioning hole 23 through the lower positioning pin 34. This achieves a stable fit between the upper fixing plate 10, the product positioning plate 20, and the lower fixing plate 30. Specifically, after the testing device is pressed together, the upper fixing plate 10 presses down on the PogoPin product 100 to be tested. The tail of the PogoPin product 100 is pressed down to the preset working height. After the tail of the PogoPin product 100 is pressed down, it contacts the test surface of the test probe 50, causing the tail of the test probe 50 to press down synchronously. The wire soldered to the tail is a flexible wire that can move with the tail of the test probe 50. After pressing, the entire device forms a series circuit with the product and the test probe, which is used to test multiple products simultaneously.

[0040] In one embodiment of this utility model, such as Figure 6As shown, the test probe 50 includes a test needle 51, a test needle tube 52, a fastening ring 53, and a spring 54. An outer ring 511 is formed around the outer periphery of the test needle 51, an outer ring 521 is formed at the top of the test needle tube 52, and an inner ring 522 is formed at the bottom of the test needle tube 52. The spring 54 is sleeved outside the test needle 51, and the test needle 51 passes through the test needle tube 52. The upper end of the spring 54 abuts against the outer ring 511, and the lower end of the spring 54 abuts against the inner ring 522. The fastening ring 53 is interference-fitted onto the outer periphery of the test needle 51 as it passes through the test needle tube 52. When the test probe 50 is placed in the countersunk limiting hole 31, the step of the countersunk limiting hole 31 supports the outer ring 521. Specifically, the test needle 51 and the fastening ring 53 are interference-fitted into an integral rod structure to prevent detachment. When the test needle 51 contacts the PogoPin product 100 and is pressed down, the retaining ring 53 and the test needle 51 move downwards accordingly. The spring 54 is used to maintain the upward pushing force of the product, and when it contacts the PogoPin product 100, the contact surface of the test needle 51 is subjected to the pressure of the spring 54, so as to make the contact more complete.

[0041] The integrated PogoPin rapid tandem testing device of this utility model has the following features:

[0042] 1. The testing device is mainly divided into three parts: upper fixing plate 10, product positioning plate 20 and lower fixing plate 30;

[0043] 2. Assembled together with the upper fixing plate 10 are an upper positioning pin 12 and a conductive block 40; the upper positioning pin 12 is used for positioning during the mold closing process with the product positioning plate 20, and is made of stainless steel; the conductive block 40 is used to connect and conduct the PogoPin product 100 after mold closing, and the conductive block 40 is made of brass with a gold-plated surface to improve oxidation resistance and reduce contact resistance. Each conductive block 40 connects 2 pieces of PogoPin product 100; the upper fixing plate 10 is made of insulating material and is used to install and fix the upper positioning pin 12 and the conductive block 40. The upper fixing plate 10, the upper positioning pin 12, and the conductive plate are assembled together by interference fit.

[0044] 3. The lower fixing plate 30 is assembled as a whole, including a test probe 50, a lower positioning pin 34, and a conductive wire harness. The test probe 50 is used to make contact with the PogoPin product 100 under test. Because the tail of the PogoPin product 100 under test moves downwards during pressing, the test probe 50 can move downwards accordingly. The lower positioning pin 34 is used for positioning with the product positioning plate 20 during the mold closing process and is made of stainless steel. The conductive wire harness is soldered to the tail of the test probe 50 using chrome plating. There are several conductive wire harnesses, each connecting two test probes 50 in a staggered series connection, utilizing the flexibility of the conductive wire harness. The lower fixing plate 30 is made of insulating material and is used to install the test probe 50, the lower positioning pin 34, and the conductive wire harness. The front of the lower fixing plate 30 has a countersunk limiting hole 31 for controlling the downward pressure height of the test probe 50 and a center positioning hole 23 for installing the test probe 50. The countersunk limiting hole 31 ensures that the test surface of the test probe 50 is 1mm higher than the surface of the lower fixing plate 30 (if there are other working height requirements, the depth of the countersunk limiting hole 31 can be changed to accommodate different PogoPin products 100 for testing). The bottom surface has a welding groove for pre-installed conductive wire harness.

[0045] 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.
