Description

Technical Field

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

[0002] In the current PogoPin product manufacturing industry, it is necessary to test the contact conductivity, power-on lifespan, and batch parallel withstand voltage of integrated PogoPin products. Due to the structural characteristics of integrated PogoPin products, 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 meet the movement space required when the product is compressed.

[0003] However, due to its structural characteristics, the integrated PogoPin product requires individual wire bonding to each product when it is conducting. Furthermore, the product's small size makes wire bonding inefficient. This inefficiency is particularly pronounced when conducting large-scale sampling tests. If the test is a parallel test, the main line needs to be divided into several parallel branches, making the branching of the lines and the positioning and clamping of the products very complex. Disassembling and reassembling the product is also extremely inconvenient if a defective product needs to be replaced.

[0004] In the current industry practice, the number of products connected in parallel is typically reduced, and custom-designed test hosts are used in parallel. However, because resoldering is required each time, the lifespan of the test host is easily damaged, resulting in high testing costs. Each batch of tests typically lasts 96 to 144 hours, and if product defects are found during testing, replacement is slow.

[0005] This situation with existing technologies results in long development cycles, high labor costs, and high material costs for R&D investment. Utility Model Content

[0006] The purpose of this invention is to provide an integrated PogoPin rapid parallel 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 conduct batch testing of product electrical performance.

[0007] To achieve the above objectives, this utility model provides an integrated PogoPin rapid parallel testing device, comprising an upper fixing plate, a product positioning plate, a lower fixing plate, a conductive block, and multiple test probes. The conductive block is fixed to the bottom of the upper fixing plate. The lower fixing plate is provided with multiple spaced recessed limiting holes, each containing one test probe. The test probes are arranged in sequence, with each pair of adjacent test probes forming a group, and their bottoms connected via a power cable harness. The product positioning plate is disposed between the lower fixing plate and the upper fixing plate, and is provided with product positioning holes corresponding one-to-one with the positions of each recessed limiting hole. The product positioning holes are used to place the PogoPin product to be tested. The conductive block's orthographic projection covers all the product positioning holes.

[0008] Optionally, the bottom of the upper fixing plate is provided with a conductive block groove, and the conductive block is embedded in the conductive block groove and is flush with the bottom surface of the upper fixing plate.

[0009] Optionally, the bottom of the lower fixing plate is provided with a wire-recessed groove for accommodating each of the power cable harnesses.

[0010] Optionally, the integrated PogoPin rapid parallel testing device further includes two conductive cables, which are electrically connected to the test probe and the conductive block located at the tail end of the parallel circuit, respectively.

[0011] 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.

[0012] 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.

[0013] The integrated PogoPin rapid parallel testing device provided in this utility model embodiment has at least one of the following technical effects: During use, the PogoPin product is positioned into the positioning hole of the product positioning plate using a aligning machine or manually, and the positioning status and consistency of the PogoPin product are checked; then, the product positioning plate with the PogoPin product installed is closed with the lower fixing plate; after closing the mold, 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. The positioning is stable. Next, the upper fixing plate is placed over the product positioning block. Due to the free elasticity of the PogoPin products, the upper fixing plate after molding is in a floating state, lifted by the PogoPin products. A conductive block contacts all the PogoPin products. The test probes are arranged in sequence, with each pair of adjacent probes forming a group, and their bottoms connected via power cables, ensuring uninterrupted cable routing and forming a parallel network structure. Finally, the molded test module is placed into the pressing device, and the device is pressed down to mold the test module. After molding, the test module is fixed, and the product, limited by height, is positioned at a uniform working height. 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 R&D material costs, and increases sampling accuracy. Attached Figure Description

[0032] 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 1-8The described embodiments are exemplary and intended to explain embodiments of the present invention, and should not be construed as limiting the present invention.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] In one embodiment of this utility model, such as Figures 1-7 As shown, an integrated PogoPin rapid parallel testing device is provided, including an upper fixing plate 10, a product positioning plate 20, a lower fixing plate 30, a conductive block 40, and multiple test probes 50. The conductive block 40 is connected and fixed to the bottom of the upper fixing plate 10. The lower fixing plate 30 is provided with multiple spaced recessed limiting holes 31, and each recessed limiting hole 31 holds one test probe 50. The test probes 50 are arranged in sequence, with each pair of adjacent test probes forming a group, and their bottoms are connected by a power cable harness 60. The product positioning plate 20 is disposed 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 recessed limiting hole 31. The product positioning holes 21 are used to place the PogoPin product 100 to be tested. The conductive block 40 orthogonally covers all the product positioning holes 21.

[0037] When using the integrated PogoPin rapid parallel 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; then, the product positioning plate 20 with the PogoPin product 100 installed is closed with the lower fixing plate 30; after closing the mold, the PogoPin product 100 does not contact the dedicated test probe 50 in the sinking platform in the lower fixing plate 30, so the PogoPin product 100 will not be ejected, and the positioning status is stable; then... The upper fixing plate 10 is placed over the product positioning block. Due to the free elasticity of the PogoPin product 100, the upper fixing plate 10 is in a floating state after mold closing, supported by the PogoPin product 100. A conductive block 40 contacts all the PogoPin products 100. The test probes 50 are arranged in sequence, with each pair of adjacent test probes forming a group, and their bottoms connected by a power cable harness 60, thus maintaining uninterrupted cable connection and forming a parallel network structure. 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 mold closing, the test module is fixed, and the product, limited by height, is located at a uniform working height. 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 R&D material costs, and improves sampling accuracy.

[0038] The integrated PogoPin rapid parallel testing device provided in this embodiment solves the bottleneck of the inability to perform batch parallel testing of integrated PogoPin products 100. The testing device is universal and applicable to products with similar structures, without the need for customized testing host or motherboard. This improves the efficiency of testing operations, reduces development time, lowers R&D material costs, and increases sampling accuracy.

[0039] It should be further explained that, after the integrated PogoPin rapid parallel testing device provided in this embodiment of the invention is pressed together, the upper fixing plate 10 presses down on the PogoPin product 100 to be tested, and the tail of the PogoPin product 100 follows and 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 power harness 60 soldered to the tail is a flexible wire that can move with the tail of the test probe 50. After pressing, the entire testing device constructs a parallel circuit with the PogoPin product 100 and the test probe 50, which is used to test multiple PogoPin products 100 simultaneously.

[0040] 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 conductive block groove 11, and the conductive block 40 is embedded in the conductive block groove 11 and flush with the bottom surface of the upper fixing plate 10. Specifically, the embedded method ensures an interference fit between the conductive block 40 and the conductive block 40 hole, which is stable and reliable. Furthermore, being flush with the bottom surface of the upper fixing plate 10 avoids interference with other components due to steps, thereby ensuring more reliable operation.

[0041] In one embodiment of this utility model, such as Figure 4 As shown, the bottom of the lower fixing plate 30 is provided with a wire bonding relief groove 32 for accommodating each of the power cable harnesses 60. Specifically, the wire bonding relief groove 32 provides space to accommodate the power cable harnesses 60, ensuring that the two test probes 50 can be soldered in parallel. 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 flat surface.

[0042] In one embodiment of this utility model, such as Figures 1-4 As shown, the integrated PogoPin rapid parallel testing device also includes two conductive cables 70, which are electrically connected to the test probe 50 and the conductive block 40 located at the tail end of the parallel circuit, respectively. Specifically, the conductive cables 70 can be directly connected to powered equipment, which is convenient and practical.

[0043] In one embodiment of this utility model, such as Figures 1-5 As shown, 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, 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 a 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 welded to the tail is a flexible wire that can move with the tail of the test probe 50. After pressing, the entire device constructs a parallel circuit with the product and the test probe, which is used to test multiple products simultaneously.

[0044] In one embodiment of this utility model, such as Figure 8As 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.

[0045] The integrated PogoPin rapid parallel testing device of this utility model has the following features:

[0046] 1. The testing device consists of three main parts: upper fixing plate 10, product positioning plate 20 and lower fixing plate 30.

[0047] 2. The upper fixing plate 10 is assembled as a whole, including the upper positioning pin 12, the conductive block 40, and the upper fixing plate 10.

[0048] 2.1 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;

[0049] 2.2 The conductive block 40 is used to connect and conduct PogoPin product 100 after mold closing. The conductive block 40 is made of brass with gold plating to improve oxidation resistance and reduce contact resistance. The conductive block 40 is a whole and can be connected in parallel to several products to be tested.

[0050] 2.3 The upper fixing plate 10 is made of insulating material and is used to install the upper positioning pin 12 and the conductive block 40. The upper positioning pin 12 and the conductive plate are assembled into one piece with the upper fixing plate 10 by interference fit.

[0051] 3. The lower fixing plate 30 is assembled as a whole, including the test probe 50, the lower positioning pin 34 and the lower fixing plate 30.

[0052] 3.1 The test probe 50 is used to make contact with the PogoPin product 100 under test. Since the tail of the PogoPin product 100 moves downwards during pressing, the test probe 50 is designed as an elastic contact needle that can follow this downward movement. It consists of four parts: a test needle head 51, a spring 54, a test needle tube 52, and a fastening ring 53, assembled into a single unit through compression. The probe parts are made of brass with a gold-plated surface to improve oxidation resistance and reduce contact resistance. The spring 54 is made of piano wire to ensure service life. Each test probe 50 corresponds to one PogoPin product 100 under test.

[0053] 3.2 The lower positioning pin 34 is used for positioning during the mold closing process with the product positioning plate 20, and is made of stainless steel;

[0054] 3.3 The lower fixing plate 30 is made of insulating material and is used to install the test probe 50 and the lower positioning pin 34. The front of the lower fixing plate 30 has a countersunk limiting hole 31 and a lower positioning hole 33 for controlling the downward pressure height of 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 fixing plate (if there are other working height requirements, the depth of the countersunk hole can be changed to accommodate different product tests). The bottom surface has a wire bonding clearance groove 32 for pre-installing the power harness 60.

[0055] 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.
