[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0044] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0045] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B as an example", it includes solution A, or solution B, or a solution that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0046] Electronic products, that is, products based on electricity, include smart doorbells, smart speakers, game consoles, tablets and other products that require power supply. Before these types of electronic products are assembled and shipped, they usually need to be tested by testing equipment to perform various functional tests such as voltage performance and voice performance tests, in order to ensure that the subsequent electronic products shipped have normal and stable functions.

[0047] In the process of functional testing of electronic products, in order to facilitate the electrical connection between the test equipment and the electronic product to be tested, the test equipment is usually provided with test electrodes that are electrically connected to the electronic product to be tested. However, the connection of the test electrodes in the test equipment in the current industry is generally complicated and cannot be disassembled. As a result, when the test electrodes are damaged, more parts need to be disassembled and replaced. In short, it is currently difficult to maintain the test electrodes used to electrically connect electronic products and test equipment.

[0048] Therefore, based on the above considerations, in order to solve the problem of difficult maintenance of test electrodes in the current industry, the present application proposes a new type of test electrode assembly. The test assembly innovatively sets an electrical connector for transitional connection between the test electrode and the test equipment, so that the original electrical connection between the test electrode and the test equipment is transferred to between the electrical connector and the test equipment, and at the same time, the test electrode is set on the electrical connector as a relatively simple detachable connection, thereby greatly simplifying the connection structure of the test electrode, so as to improve the convenience of subsequent maintenance of the test electrode.

[0049] Among them, it should be noted that the test electrode assembly proposed in this application can be used for functional testing of smart doorbells, and of course it can also be used for functional settings of products such as smart speakers and game consoles, as long as it involves electronic products that need to be powered. And when in use, the test electrode assembly can be used in conjunction with the test equipment. After obtaining the data collected by the test electrode assembly, the test equipment can analyze it to determine whether the corresponding performance of the tested electronic product is qualified. Even when the test equipment has a display screen, the test results can be implemented on the display screen so that the test equipment can provide more intuitive feedback on the test results.

[0050] Next, the structure of the test electrode assembly proposed in this application is explained with a specific embodiment. In one embodiment of this application, please refer to Figures 1 to 3 The test electrode assembly 100 proposed in the present application includes a mounting carrier 10 , an electrical connector 30 and a test electrode 50 . The electrical connector 30 is disposed on the mounting carrier 10 ; the test electrode 50 is detachably mounted on the electrical connector 30 .

[0051] The mounting carrier 10 can be used to provide a mounting position for installing the electrical connector 30 and the like. At the same time, the mounting carrier 10 can also be made of an insulating material so as to provide insulation protection for the electrical connector 30. In order to allow the mounting carrier 10 to have a relatively small wall thickness so as to reduce the overall volume of the test electrode assembly 100 while still having a high strength, the material of the mounting carrier 10 can specifically be polyetheretherketone. Of course, the mounting carrier 10 can also be other plastics or insulating materials. In addition, the mounting carrier 10 can be in the form of a seat structure, of course, it can be in the form of a plate structure, or in the form of a column structure. The present application does not limit the specific structural form and shape of the mounting carrier 10, and it is sufficient to ensure that it can be used to install and carry the electrical connector 30.

[0052] The electrical connector 30 can be used to provide an installation position for installing the test electrode 50. At the same time, the electrical connector 30 can also be used to electrically connect the test equipment. Therefore, in other words, the electrical connector 30 can serve as a transitional conductive component between the test electrode 50 and the test equipment. At this time, compared with the test electrode 50, which needs to be in contact with the electronic product to be tested during the test, so that the test electrode 50 is easily damaged after multiple tests, the electrical connector 30 does not need to be in contact with the electronic product to be tested, so that the electrical connector 30 is not easy to be damaged and can be used for a relatively long time. Therefore, after the test electrode assembly 100 is used many times, it is mainly the test electrode 50 that is easily damaged, so that the test electrode 50 mainly needs to be maintained accordingly. In addition, the electrical connector 30 can be directly electrically connected to the test equipment. Of course, when the test electrode assembly 100 is combined with the battery module and the circuit board to form a test module as described below, the electrical connector 30 can also be electrically connected to the electrical board, and then the circuit board is electrically connected to the test equipment. That is, the electrical connector 30 can be directly or indirectly electrically connected to the test equipment. In addition, the electrical connector 30 can be made of metal material so that it has good electrical conductivity and strong strength, so as to improve the stability of the installation and bearing of the test electrode 50. Of course, the material of the electrical connector 30 can also be other materials that can conduct electricity (such as graphite, etc.). The structural form of the electrical connector 30 can be a combination of a main body tube 33 and a connecting tube 35 as described below, and of course it can also be a plate structure or a block structure. The specific structural form and shape of the electrical connector 30 are not limited in this application.

[0053] The test electrode 50 can be electrically connected to the electronic product. Specifically, the electronic product can have a battery compartment, and the battery compartment can have charging contacts. At this time, when testing the electronic product, the test electrode 50 can be electrically connected to the charging contacts on the battery product to realize the direct use of the charging contacts in the battery compartment of the electronic product. Among them, the number of test electrodes 50 can be at least two, so that the electrode group corresponding to the positive and negative electrodes is formed by two test electrodes 50. At this time, the number of electrode groups can be at least two groups, so that electrical signals and communication signals can be transmitted through different electrode groups, which is conducive to improving the stability of signal transmission, so as to improve the accuracy of subsequent testing of electronic products. When the number of test electrodes 50 is at least two, the electrical connector 30 can also be correspondingly provided with at least two, so that each test electrode 50 can be installed on an electrical connector 30 accordingly. Of course, the number of electrical connectors 30 can also be one, and at least two test electrodes 50 can be installed together on an electrical connector 30. The detachable installation of the test electrode 50 on the electrical connector 30 means that after the test electrode 50 is installed and connected to the electrical connector 30, the test electrode 50 can still be removed from the electrical connector 30. The detachable installation method of the test electrode 50 on the electrical connector 30 can be an interference fit of the test electrode 50 on the electrical connector 30 as described below, or of course, it can also be connected by a snap-on connection. The present application does not limit the specific connection method of the test electrode 50 on the electrical connector 30, and ensures that the test electrode 50 can be disassembled for subsequent disassembly and maintenance.

[0054] When the test electrode assembly 100 of the technical solution of the present application is in use, since the test electrode 50 is installed on the electrical connector 30, it can be electrically connected to the test equipment through the electrical connector 30, thereby realizing an indirect electrical connection between the test electrode 50 and the test equipment. That is, the test electrode 50 in this solution can transfer the original electrical connection between the test electrode 50 and the test equipment to between the electrical connector 30 and the test equipment through the setting of the electrical connector 30; at the same time, the test electrode 50 is installed on the electrical connector 30 in a relatively simple detachable connection manner. In this way, when the test electrode 50 is damaged, the test electrode 50 can be directly removed from the electrical connector 30 without being affected by the electrical connection with the equipment, thereby improving the convenience of maintaining the test electrode 50.

[0055] Please refer to Figures 3 to 5 In one embodiment of the present application, the electrical connector 30 is provided with a plug hole 31 , and one end of the test electrode 50 is detachably plugged into the plug hole 31 .

[0056] In this embodiment, by providing a plug hole 31 on the electrical connector 30, the test electrode 50 can be directly plugged and connected. In this way, the connection structure between the test electrode 50 and the electrical connector 30 can be further simplified, which is conducive to further improving the convenience of disassembly and assembly of the test electrode 50, so as to facilitate the subsequent maintenance of the test electrode 50. On the other hand, the connection part between the test electrode 50 and the electrical connector 30 can also be hidden through the plug hole 31, which is conducive to improving the isolation and protection of the connection part between the test electrode 50 and the electrical connector 30, so as to reduce the possibility of damage to the two at the connection point, so as to ensure the stability of the connection between the test electrode 50 and the electrical connector 30, so that the test electrode 50 can perform normal and stable testing. In addition, part of the test electrode 50 can also be accommodated through the plug hole 31, so that the test electrode 50 can be arranged more compactly on the electrical connector 30, which is conducive to reducing the overall volume of the test electrode assembly 100, so that it can be used for testing in the limited space in the battery compartment of the electronic product. Of course, in other embodiments, it is also possible for the testing electrode 50 to be directly clamped or clamped on the outer side of the electrical connector 30 .

[0057] In one embodiment of the present application, the test electrode 50 and the plug hole 31 are arranged in an interference fit.

[0058] In the present embodiment, since the test electrode 50 and the plug hole 31 are interference fit, the test electrode 50 can be tightly held and limited by the hole wall of the plug hole 31 after being inserted into the plug hole 31. Therefore, at this time, there is no need to set up an additional structure for limiting the test electrode 50 in the plug hole 31, so that the structure of the plug hole 31 can be very simple, which is conducive to further simplifying the connection structure between the test electrode 50 and the electrical connector 30, so as to improve the convenience of disassembly and assembly. Of course, in other embodiments, when the test electrode 50 is not set with an interference fit with the plug hole 31, a snap-on portion or a magnetic attraction portion can be provided in the plug hole 31, so that the test electrode 50 can be snap-connected or magnetically connected in the plug hole 31.

[0059] Please refer to Figures 3 to 5 In one embodiment of the present application, in the center line direction of the plug hole 31, the test electrode 50 includes a mounting section 51 and a test section 53 connected in sequence, and the cross-sectional area of ​​the mounting section 51 is larger than the cross-sectional area of ​​the test section 53; the mounting section 51 is detachably inserted into the plug hole 31, and at least part of the test section 53 is located outside the plug hole 31.

[0060] In this embodiment, the test electrode 50 is configured to include a mounting section 51 with a relatively large cross-sectional area and a test section 53 with a relatively small cross-sectional area, so that the test electrode 50 can be strengthened by the mounting section 51, thereby facilitating the improvement of the overall strength of the test electrode 50, so as to reduce the possibility that the test electrode 50 is bent and damaged and cannot be accurately electrically connected to the electronic product. The test electrode 50 can reduce the volume of this part by the test section 53 with a relatively small cross-sectional area, so that it can smoothly electrically contact and conduct with the charging contacts in the battery compartment within the limited space in the battery compartment of the electronic product. In addition, the test electrode 50 is plugged into the plug hole 31 on the electrical connector 30 through the mounting section 51 with a relatively large cross-sectional area, which also increases the contact area between the two, thereby facilitating the improvement of the stability of the test electrode 50 installed on the electrical connector 30, so that the test electrode 50 can perform normal and stable testing work later. Therefore, the test electrode 50 including the aforementioned mounting section 51 and the test section 53, on the one hand, can enhance the strength of the test electrode 50 itself and prevent bending, and on the other hand, can stably install the test electrode 50 at a preset mounting position on the electrical connector 30, so that the test electrode 50 can improve the accuracy of its contact with the charging contact on the electronic product during the test process through these two aspects, so as to reduce the impact of the performance of the non-electronic product itself on the test results, thereby improving the accuracy of the performance test results of the electronic product. Among them, the cross-sections of the mounting section 51 and the test section 53 in the test electrode 50 can both be circular, so that they have consistency all around and improve the convenience of processing and forming. Of course, the cross-sections of the mounting section 51 and the test section 53 in the test electrode 50 can also be square or other shapes, which is not limited in this application. When the test electrode 50 and the plug hole 31 are set in an interference fit, the mounting section 51 in the test electrode 50 and the mounting hole 11 can be set in an interference fit. Furthermore, through the installation section 51 with a relatively large cross-sectional area, the test section 53 can also be provided with an installation position, so that one end of the test section 53 can be retractably inserted and installed in the installation section 51, and an elastic member (for example: a spring, a spring sheet, or a plastic member with a certain elasticity) is arranged between the test section 53 and the installation section 51. At this time, when the test electrode 50 abuts against the charging contact on the electronic product through the test section 53, it can play a buffering role by compressing the elastic member, thereby reducing the direct hard abutment between the two and prone to collision damage or wear damage, thereby helping to improve the protection of the test electrode 50. Of course, it is also possible that the test electrode 50 only includes a combination of solid segments with different cross-sectional areas at both ends, or it is also possible that the test electrode 50 is formed by a segment with a uniform cross-section.

[0061] Please refer to Figures 3 to 5In one embodiment of the present application, in the centerline direction of the plug hole 31 , the length value of the mounting section 51 is the same as the depth value of the plug hole 31 .

[0062] In the present embodiment, the mounting section 51 is completely disposed in the plug hole 31, so that the plug hole can protect the mounting section 51 as a whole, thereby facilitating the protection of the test electrode 50 and reducing the possibility of bending and damage thereof affecting the subsequent testing work of the test electrode 50. At the same time, the contact area between the test electrode 50 and the electrical connector 30 is also increased, which can improve the stability of the installation of the test electrode 50, thereby facilitating the subsequent normal and stable testing work of the test electrode 50. Furthermore, the length value of the mounting section 51 and the depth value of the plug hole 31 also ensure that the plug hole 31 will not block or hide the test section 53, so that the test section 53 can be fully exposed to perform the subsequent required test abutment work. Of course, in other embodiments, it is also possible to set the length value of the mounting section 51 and the depth value of the plug hole 31 to be different.

[0063] Please refer to Figure 3 and Figure 5 In one embodiment of the present application, the electrical connector 30 includes a main body tube 33 and a connecting tube 35, and the two opposite ends of the main body tube 33 are open; the connecting tube 35 is connected to one end of the main body tube 33, and the inner side of the connecting tube 35 and the inner side of the main body tube 33 are combined to form a plug-in hole 31.

[0064] In this embodiment, by setting the electrical connector 30 as a combination of the main body tube 33 and the connecting tube 35, the shape of the electrical connector 30 can be relatively consistent with the shape of the test electrode 50, that is, both can be rod structures. At this time, the adaptability between the electrical connector 30 and the test electrode 50 can be improved, so as to improve the compactness of the distribution of the two, thereby helping to reduce the overall volume of the test electrode assembly 100, so as to improve the convenience of using it in a limited space later. At the same time, the structure of the electrical connector 30 can also be very simple, that is, the plug hole 31 can be a through-hole structure on the electrical connector 30, which is conducive to improving the convenience of processing and forming it. Among them, the connecting tube 35 can be opened only at one end close to the main body tube 33, and of course, it can also be further opened at one end of the original main body tube 33 to further simplify the structure of the electrical connector. In addition, in other embodiments, the connecting tube 35 can also be replaced by a connecting column. In other words, the electrical connector 30 is formed by the main body tube 33 and the connecting column.

[0065] Please refer to Figures 3 to 6In one embodiment of the present application, the mounting carrier 10 is provided with a mounting hole 11, and at least a portion of the main body tube 33 is installed in the mounting hole 11; the mounting hole 11 has a first opening 111 and a second opening 113 that are arranged opposite to each other, at least a portion of the connecting tube 35 passes through the first opening 111, and at least a portion of the test electrode 50 passes through the second opening 113.

[0066] In this embodiment, the main body tube 33 is accommodated and installed by providing the installation hole 11, so that the electrical connector 30 can be directly plugged and installed on the installation carrier 10. In this way, the connection structure between the electrical connector 30 and the installation carrier 10 can be simplified, which is conducive to improving the convenience of installing the electrical connector 30 on the installation carrier 10. On the other hand, the connection part between the electrical connector 30 and the installation carrier 10 can also be hidden through the installation hole 11, which is conducive to improving the isolation and protection of the connection part between the electrical connector 30 and the installation carrier 10, so as to reduce the possibility of damage to the two at the connection point, which is conducive to ensuring the stability of the connection between the electrical connector 30 and the installation carrier 10. In addition, the mounting hole 11 can also accommodate part of the electrical connector 30, so that the electrical connector 30 can be arranged more compactly on the mounting carrier 10, especially when the above-mentioned test electrode 50 is also inserted and installed on the electrical connector 30, the compactness of the distribution of several test electrodes 50 can be improved, so as to further reduce the overall volume of the test electrode assembly 100, so as to be used for testing in the limited space of the battery compartment of the electronic product. In addition, at least part of the connecting tube 35 passes through the first opening 111, which can be conveniently connected to the circuit board described below through the connecting tube 35, or directly to the test equipment. And at least part of the test electrode 50 passes through the second opening 113, so that the test section 53 in the test electrode 50 can pass through the second opening 113, so as to abut and conduct with the charging contact on the electronic product. Further, it should be noted that in other embodiments, it is also possible for the electrical connector 30 to be directly clamped or clamped on the outside of the mounting carrier 10.

[0067] Please refer to Figure 3 , Figure 5 as well as Figure 6 In one embodiment of the present application, one of the side surface of the main tube 33 and the hole wall of the mounting hole 11 is provided with a limiting protrusion 331, and the other one is provided with a limiting groove 115, and the limiting protrusion 331 and the limiting groove 115 are arranged in an interference fit.

[0068] In this embodiment, the main body tube 33 is limited in the mounting hole 11 by the interference fit between the limiting protrusion 331 and the limiting groove 115, which can make the limiting of the electrical connector 30 very simple, thereby simplifying the structure of the mounting carrier 10 and the electrical connector 30, so as to improve the convenience of its manufacture and assembly. Moreover, the main body tube 33 in the electrical connector 30 is only partially interfered with the hole wall of the mounting hole 11, so that when the main body tube 33 is provided with the limiting protrusion 331, the side surface of the main body tube 33 will only undergo elastic deformation in the area where the limiting protrusion 331 is provided; and when the main body tube 33 is provided with the limiting groove 115, the side surface of the main body tube 33 will not undergo elastic deformation. Therefore, at this time, it can be said that the main body tube 33 will only partially deform elastically on the side circumference at most, so that when the main body tube 33 of the electrical connector 30 is inserted and installed on the mounting carrier 10, it will not affect the plug-in hole 31 inside the main body tube 33, which is conducive to ensuring the subsequent accurate insertion of the mounting section 51 of the test electrode 50 into the plug-in hole 31. Of course, in other embodiments, when the main body tube 33 is not arranged in an interference fit with the mounting hole 11 through the cooperation of the limiting protrusion 331 and the limiting groove 115, a snap-fit ​​portion or a magnetic attraction portion can be provided in the mounting hole 11, so that the electrical connector 30 can be snap-connected or magnetically connected in the mounting hole 11.

[0069] Please refer to Figure 3 In one embodiment of the present application, when a limiting protrusion 331 is provided on the side circumference of the main tube 33 , the side circumference of the main tube 33 except the limiting protrusion 331 abuts against the hole wall of the mounting hole 11 .

[0070] In this embodiment, the limiting protrusion 331 is arranged on the main body tube 33, so that there is no requirement for the wall thickness of the main body tube 33 due to the similarly arranged slot structure, which is conducive to improving the convenience of manufacturing the electrical connector 30. Furthermore, the side surface of the main body tube 33 except the limiting protrusion 331 abuts against the hole wall of the mounting hole 11, so that the hole wall of the mounting hole 11 can have an abutting and guiding effect on the insertion and installation of the electrical connector 30 on the mounting carrier 10, which is conducive to improving the accuracy of the installation of the electrical connector 30 on the mounting carrier 10. At the same time, the hole wall of the mounting hole 11 can also increase the contact area between the mounting carrier 10 and the electrical connector 30, which is conducive to improving the stability of the installation of the electrical connector 30 on the mounting carrier 10.

[0071] Please refer to Figure 3 , Figure 5 as well as Figure 6 In one embodiment of the present application, one end of the main body tube 33 away from the connecting tube 35 and the second opening 113 are arranged flush.

[0072] In this embodiment, the main body tube 33 is arranged at one end away from the connecting tube 35 and is flush with the second orifice 113, so that the mounting hole 11 can wrap a larger part of the electrical connector 30. At this time, it can be said that the test electrode 50 is further protected by the mounting carrier 10 on the basis of being sheathed with the above-mentioned electrical connector 30 on the outside for protection. In this way, the protective effect of the test electrode 50 can be improved, so that only the test section 53 in the test electrode 50 that needs to be electrically connected to the electronic product is exposed to the outside, thereby reducing the possibility of the test electrode 50 being damaged or bent by foreign objects, so that the test electrode 50 can have a longer effective working time and reduce the maintenance frequency thereof. On the other hand, since the main body tube 33 is flush with the second orifice 113, the main body tube 33 can be exposed from the second orifice 113. In this way, when the assembler inserts and installs the test electrode 50 into the plug hole 31 of the electrical connector 30, it is convenient for the assembler to ensure that each test electrode 50 can have a consistent insertion depth on each electrical connector 30 by observing the flush relationship between the step formed between the installation section 51 and the test section 53 in the test electrode 50 and the end of the main tube 33 away from the connecting tube 35. In addition, it should be noted that in other embodiments, it is also possible for the end of the main tube 33 away from the connecting tube 35 to be higher or lower than the second opening 113.

[0073] Please refer to Figure 3 and Figure 5 In one embodiment of the present application, one end of the connecting tube 35 close to the main body is located in the mounting hole 11, and the connecting tube 35 located in the mounting hole 11 and the hole wall of the mounting hole 11 are spaced apart.

[0074] In this embodiment, the connection tube 35 is partially set in the mounting hole 11, so that it can be distributed more compactly on the mounting carrier 10, so as to reduce the overall volume of the test electrode assembly 100. Further, there is a gap between the connection tube 35 located in the mounting hole 11 and the hole wall of the mounting hole 11, so that the connection tube 35 can be deformed in a direction perpendicular to the center line of the mounting hole 11. Therefore, when the connection tube 35 is connected to the circuit board described below or directly connected to the test equipment, even if the connection tube 35 is affected by some forces in the direction perpendicular to the center line of the mounting hole 11 during the connection process, it will only drive the connection tube 35 to deform, and will not be transmitted to the mounting carrier 10 and the main body tube 33, so as to ensure the stability of the installation of the electrical connector 30 on the mounting carrier 10. Of course, in other embodiments, it is also possible to set the connection tube 35 located in the mounting hole 11 and the hole wall of the mounting hole 11 to abut. Alternatively, it is also possible to set the connection tube 35 completely outside the mounting hole 11.

[0075] Please refer to Figure 3 and Figure 6 In one embodiment of the present application, the mounting carrier 10 includes a first seat body 13 and a second seat body 15, the first seat body 13 is provided with a first hole body 11a; the second seat body 15 is connected to the first seat body 13, the second seat body 15 is provided with a second hole body 11b, the second hole body 11b is connected to the first hole body 11a, and is combined with the first hole body 11a to form a mounting hole 11, a first hole opening 111 is formed at one end of the first hole body 11a away from the second hole body 11b, and a second hole opening 113 is formed at one end of the second hole body 11b away from the first hole body 11a; on a projection plane perpendicular to the center line of the mounting hole 11, the projection of the second seat body 15 is located on the inner side of the projection of the first seat body 13.

[0076] In this embodiment, the mounting carrier 10 is set as a combination of a first base body 13 and a second base body 15, and the second base body 15 is relatively small in projection on a projection plane perpendicular to the center line of the mounting hole 11, so that the profile of the end of the test electrode assembly 100 close to the test section 53 with the test electrode 50 is relatively small, and the space with a charging contact in the battery compartment of the electronic product is often relatively limited. Therefore, setting the profile of the end of the test electrode assembly 100 close to the test section 53 with the test electrode 50 relatively small can reduce the possibility of interference between the test electrode assembly 100 and the structure on the electronic product during the actual test of the electronic product, thereby facilitating the safety of the electronic product test process. Setting the profile of the end of the mounting carrier 10 far from the test section 53 to be relatively large can improve the overall strength of the mounting carrier 10 on the one hand, and facilitate its subsequent installation on the circuit board described below on the other hand.

[0077] The present application also proposes a test module, which includes a module carrier, a battery module, and a test electrode assembly 100. The specific structure of the test electrode assembly 100 refers to the above embodiment. Since the present test module adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the battery module is arranged on the module carrier; the circuit board is arranged on the module carrier and electrically connected to the battery module; the electrical connector 30 in the test electrode assembly 100 is electrically connected to the circuit board. The module carrier can be used to provide a mounting position to install the battery module and the circuit board, so as to facilitate the assembly of the partial structure to form an integral structure. The module carrier can be in the form of a shell to protect the electronic module. Of course, the module carrier can also be in other structural forms. The battery module can be used for power supply, and the circuit board can control the power supply of the battery module, and can also collect voltage information or other information for electronic products.

[0078] In this embodiment, since the test electrode assembly 100, the battery module and the circuit board are integrated into one module, a mechanical structure foundation is provided to realize the automated testing of electronic products. Specifically, since the battery module and the circuit board are set independently of the test equipment, the test module can be installed in the battery compartment of the electronic product to be tested, thereby realizing the autonomous power supply and information data collection of each electronic product to be tested by the test module. After that, when the test module follows the electronic product to be transferred to the test equipment with different functional tests, each test equipment can directly exchange information with the circuit board on the test module installed on the electronic product. Therefore, such a setting makes it convenient for each test equipment to quickly complete the docking test of the electronic product during the transfer process of the electronic product, thereby facilitating the efficient automated testing of the electronic product.

[0079] In one embodiment of the present application, the electrical connector 30 is soldered to the circuit board.

[0080] In this embodiment, the connecting tube 35 in the electrical connector 30 is welded to the circuit board, so that when the mechanical connection between the electrical connector 30 and the circuit board is completed, the electrical connection between the two is also completed at the same time, which is conducive to simplifying the connection structure between the two. Moreover, the welding fixation method also has the advantages of being simple and reliable, which is conducive to simplifying the installation process of the electrical connector 30 on the circuit board and improving the stability of the connection between the electrical connector 30 and the circuit board. Of course, in other embodiments, the electrical connector 30 can also be attached to the circuit board through a conductive adhesive.

[0082] In this embodiment, the positioning column 17 and the positioning hole cooperate to position the mounting carrier 10 on the circuit board, and the electrical connector 30 is mounted on the mounting carrier 10. Therefore, in other words, it can be said that the electrical connector 30 is positioned, which is conducive to improving the accuracy of the connection between the test electrode 50 and the circuit board, so that the subsequent test electrode 50 can perform the test work normally and effectively, so as to further improve the accuracy of the test results of the electronic product. There can be at least two positioning columns 17, which are respectively arranged on opposite sides of the first seat 13 of the mounting carrier 10.

Among them, the test device is electrically connected to the circuit board in the test module, and the test device can interact with the circuit board in the test module to control the operation of the test module and receive the test data transmitted by the test module. After that, the test device compares and analyzes the test data and the pre-stored qualified data, it can determine whether the test of the electronic product is qualified. Even when the test device has a display screen, the test data and analysis results tested on the electronic product can be directly displayed on the display screen more intuitively.

[0084] In one embodiment of the present application, the test module is provided with a first electrical connection portion, which is electrically connected to the circuit board; the test system also includes a transmission mechanism, which is used to transport the test module, and at least two test stations are formed on the transport path of the transmission mechanism; the number of test devices is at least two, each test device is arranged at a test station, and each test station is provided with a second electrical connection portion, which is electrically connected to the corresponding test device; when the test module is transported to each test station, the first electrical connection portion in the test module and the second electrical connection portion in the test station are correspondingly conductive.

[0085] In this embodiment, the test module can be installed in the battery compartment of the corresponding electronic product, and then the whole formed by the assembly of the test module and the electronic product is placed on the transmission mechanism for transportation. At this time, the transmission mechanism can pass the whole formed by the assembly of the test module and the electronic product through each test station in turn, and when arriving at a certain test station, the first electrical connection part on the test module can be abutted and connected with the second electrical connection part in the test station to realize the electrical connection between the test module and the test equipment in the test station. Therefore, it is convenient for each electronic product to be tested to be transported to each test station through the transmission mechanism after matching the test module to realize efficient automated testing, so as to greatly improve the test efficiency of the electronic product. Among them, the first electrical connection part can be arranged on the installation carrier 10 in the test module, or it can be arranged on the circuit board in the test module, and this application does not make specific restrictions on this.
