Description

[0002] Connectors are key components used to connect circuits in electronic and electrical systems and are widely used in communications, automobiles, industrial automation, aerospace, consumer electronics and other fields. In order to ensure the reliability and consistency of connectors, real-time detection is required during the connector assembly process. Common detection technologies are as follows: optical detection, using high-resolution cameras to detect whether the arrangement of terminals is correct and whether there are defects; electrical testing, checking the electrical performance of connectors through continuity testing, insulation resistance testing, high-voltage testing, etc.; mechanical testing, detecting mechanical properties such as plug-in force and durability.

[0020] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0022] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0023] The embodiment of the present invention provides a connector testing system, such as Figures 1 to 12 As shown, it includes: a material moving component 10, a positioning component 20 and a testing component 30, the material moving component 10 is used to load the connector 100 to be tested to the positioning component 20, and the positioning component 20 is used to position the connector 100 to be tested; The test assembly 30 includes a test base 31, a test head 32 and a test cylinder 33. A test base 34 is slidably connected to the test base 31, and a plurality of test heads 32 are installed on the test base 34. Limit rods 35 are installed at both ends of the test base 31. A limit frame 36 is movably sleeved on the limit rod 35. A buffer spring 37 is sleeved on the limit rod 35. One end of the buffer spring 37 abuts against the test base 34, and the other end of the buffer spring 37 abuts against the limit frame 36. The test cylinder 33 is used to drive the test head 32 to pass through the limit frame 36 along the third direction and insert into the interface 101 of the connector 100, so that the test head 32 tests the connector 100. In this embodiment, the test head 32 is electrically connected to an electrical test device known in the art, which will not be described in detail herein. The material moving assembly 10, the positioning assembly 20 and the test assembly 30 are all installed on the test housing 40.

[0024] It should be noted that the connector testing system provided by the present invention specifically includes a material shifting component 10, a positioning component 20 and a testing component 30. The material shifting component 10 is used to load the connector 100 to be tested onto the positioning component 20 for positioning, and the testing component 30 tests the electrical performance of the connector 100, thereby realizing the automated testing of the connector 100. In the process of pushing the test head 32 to insert into the connector 100 interface 101 by the test cylinder 33, the test seat 34 generates a small elastic displacement under the action of the buffer spring 37, thereby absorbing the instantaneous impact force generated by part of the insertion force, and preventing the connector 100 from being damaged due to overload force. The test head 32 can be inserted into the connector 100 under a relatively stable insertion force, so that the contact of the test head 32 is more stable and the conduction performance is better, which helps to improve the accuracy and consistency of the test data. The intervention of the buffer spring 37 reduces the frequency of mechanical impact between the test head 32 and the connector 100, helps to reduce mechanical fatigue and wear, and thus prolongs the service life of the entire test system. Therefore, the present invention solves the technical problem of large plug-in stress during the test of the test system in the prior art.

[0025] like Figures 1 to 5 As shown, the positioning assembly 20 includes a positioning frame 21 and a first positioning member 22, and a second positioning member 23, a third positioning member 24, a first positioning block 25 and a third positioning block 26 are installed on the positioning frame 21, and the first positioning block 25 is arranged parallel to the test head 32 and is arranged perpendicular to the third positioning block 26; The first positioning member 22 is used to position the top surface of the connector 100, the positioning frame 21 and the third positioning member 24 are used to position the bottom surface of the connector 100, the second positioning member 23 and the first positioning block 25 are used to position two opposite sides of the connector 100, and the third positioning block 26 is used to position a side of the connector 100 away from the test head 32. In the specific process, the positioning frame 21 is fixedly mounted on the test housing 40.

[0026] It should be noted that the positioning component 20 positions the top surface, bottom surface and three side surfaces of the connector 100 through the precise positioning cooperation of the first positioning member 22, the second positioning member 23, the third positioning member 24, the first positioning block 25 and the third positioning block 26, ensuring that the connector 100 always remains in the correct position during the test process. Each positioning member is used to position different surfaces of the connector 100, ensuring that there is no offset during the test process, and avoiding the test error caused by inaccurate positioning. The pneumatic drive system between the positioning members ensures the smooth movement and precise positioning of the parts during the positioning process. Through cylinder drive and multiple positioning, human errors and external interference are reduced, and the stability and consistency of the test process are improved. The positioning component 20 and the automated coordination of the material transfer component 10 enable the system to automatically complete the steps of positioning, testing, and unloading of the connector 100 without human intervention, support batch testing tasks, and improve production efficiency. It is particularly suitable for efficient testing of the connector 100 in a large-scale production environment.

[0027] In summary, the positioning component 20 is a multi-level, multi-directional positioning structure, which enables the connector testing system to have high precision, high stability and good adaptability, and can ensure that the connector 100 has no displacement during the test process, reduce test errors, and improve test efficiency and reliability.

[0028] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the first positioning member 22 includes a first positioning plate 221, a first connecting plate 222, a first positioning cylinder 223, a mounting plate 224, a shifting cylinder 225 and a mounting frame 226 which are connected in sequence; The displacement cylinder 225 is used to drive the first positioning plate 221 to move along the third direction, and the first positioning cylinder 223 is used to drive the first positioning plate 221 to move along the second direction, so that the first positioning plate 221 is positioned and clamped on the top surface of the connector 100, and the second direction is perpendicular to the third direction. In this embodiment, the mounting frame 226 is fixedly connected to the test housing 40.

[0029] It should be noted that by driving the first positioning plate 221 to move along the third direction through the shift cylinder 225, and driving the first positioning plate 221 to move along the second direction through the first positioning cylinder 223, the top surface of the connector 100 can be precisely clamped. Through the synergistic effect of the shift cylinder 225 and the first positioning cylinder 223, the stability of the connector 100 during the positioning process is ensured, and the displacement or loosening of the connector 100 during the test process is avoided, thereby improving the reliability and accuracy of the test. The first positioning member 22 is flexibly adjusted by the cylinder and can adapt to connectors 100 of different sizes and shapes. Whether it is a small connector 100 or a larger connector 100, it can ensure that its top surface is firmly clamped during the test process, with strong adaptability and good expansibility.

[0030] like Figures 1 to 9 As shown, a liquid inlet pipe 2211 and a liquid outlet pipe 2212 are relatively installed on the first positioning plate 221, and a serpentine liquid flow channel 2213 is provided in the first positioning plate 221; the liquid inlet pipe 2211, the liquid flow channel 2213 and the liquid outlet pipe 2212 are sequentially connected and are all used to accommodate the circulation of cooling liquid. In this embodiment, the liquid inlet pipe 2211 and the liquid outlet pipe 2212 are respectively connected to cooling liquid equipment commonly used in the art, and the cooling liquid equipment allows the cooling liquid to circulate in the liquid inlet pipe 2211, the liquid flow channel 2213 and the liquid outlet pipe 2212, which will not be described in detail here.

[0031] It should be noted that, by providing a serpentine liquid flow channel 2213, the coolant can fully circulate inside the first positioning plate 221 to cool the connector 100 during the test. The liquid flow channel 2213 increases the contact area between the coolant and the first positioning plate 221, improves the cooling efficiency, ensures that the system maintains a stable operating temperature during long-term operation, avoids equipment damage or performance degradation due to overheating, helps to ensure the test accuracy of the test head 32, avoids temperature fluctuations from interfering with the test results of the connector 100, and further improves the reliability and consistency of the test. By integrating the coolant circulation channel directly into the first positioning plate 221, the space is effectively utilized, and the connection method between the cooling system and the test assembly 30 is simplified. The close combination of the circulation of the coolant and the positioning assembly 20 not only improves the cooling efficiency, but also avoids additional external cooling devices, thereby improving the compactness and integration of the system.

[0032] like Figures 5 to 9 As shown, the first positioning plate 221 is provided with two layered first ventilation holes 2214, the liquid channel 2213 is located between the two first ventilation holes 2214, and the first positioning plate 221 is provided with second ventilation holes 2215, which are respectively connected with the opposite ends of the first positioning plate in the second direction and the two first ventilation holes 2214.

[0033] It should be noted that the combination of the serpentine liquid flow channel 2213 and the layered first ventilation holes 2214 can effectively promote the flow of coolant and accelerate the discharge of heat, significantly improving the cooling efficiency. The reasonable layout of the first ventilation holes 2214 and the second ventilation holes 2215 enables the circulation of coolant and the airflow to cooperate with each other, ensuring the uniformity and stability of the cooling effect. Through the arrangement of the first ventilation holes 2214 and the second ventilation holes 2215, the coolant can effectively exchange heat with the surface and internal flow channels of the third positioning plate 241, thereby improving the thermal management capability of the entire system.

[0034] like Figures 5 to 9 As shown, the two first ventilation holes 2214 are oppositely arranged, and the first ventilation holes 2214 include a first hole 22141, a second hole 22142 and a third hole 22143 which are sequentially connected, and the inner diameters of the first hole 22141, the second hole 22142 and the third hole 22143 are increasing; The second ventilation hole 2215 is connected to the second hole 22142, and the first hole 22141, the second hole 22142, the third hole 22143 and the second ventilation hole 2215 are all circular holes. In this embodiment, the first positioning plate 221, the liquid flow channel 2213, the first ventilation hole 2214 and the second ventilation hole 2215 form a three-dimensional heat dissipation network to effectively dissipate heat for the connector 100 during the test process.

[0035] It should be noted that, since the first ventilation hole 2214 includes the first hole 22141, the second hole 22142 and the third hole 22143 which are connected in sequence, its inner diameter is increasing, which can realize the gradual expansion of the airflow, optimize the flow of the airflow, and improve the stability of the airflow. The second ventilation hole 2215 is connected with the first hole 22141 and the second hole 22142, which further enhances the efficiency of the ventilation system and ensures the efficient heat exchange between the airflow and the coolant in the cooling system. Since the two first ventilation holes 2214 are arranged in opposite directions, an annular airflow can be formed near the first positioning plate 221, which further enhances the heat dissipation efficiency of the first positioning plate 221. Through the precise setting of the first ventilation hole 2214 and the second ventilation hole 2215, the coolant can flow evenly throughout the system, avoiding the situation of excessively high local temperature, effectively ensuring the stability and consistency of the cooling system, and extending the service life of the equipment. The first positioning plate 221 can actively dissipate heat during the process of moving and positioning.

[0036] like Figure 1 , Figure 2 , Figure 5 and Fig.10 As shown, the second positioning member 23 includes a second positioning block 231, a second connecting plate 232 and a second positioning cylinder 233 which are connected in sequence, and the second positioning block 231 is arranged corresponding to the first positioning block 25; The second positioning cylinder 233 is installed on the positioning frame 21 , and is used to drive the second positioning block 231 to move along the first direction, so that the second positioning block 231 and the first positioning block 25 position and clamp the connector 100 .

[0037] It should be noted that the second positioning block 231 is driven by the second positioning cylinder 233 to move precisely along the first direction, ensuring that the two opposite sides of the connector 100 are firmly clamped. This clamping method avoids possible displacement or instability of the connector 100 during the test process, and improves the accuracy of positioning; precise clamping and positioning reduce the pressure concentration on the connector 100, ensuring that the mechanical action during the insertion and testing process is evenly distributed, effectively reducing the risk of damage caused by improper clamping, and improving the service life and test reliability of the connector 100. The structural setting of the second positioning member 23 ensures that it can adapt to the positioning requirements of connectors 100 of different specifications.

[0038] like Figure 1 , Figure 2 , Figure 5 and Fig.11 As shown, the third positioning member 24 includes a third positioning plate 241, a third connecting plate 242 and a third positioning cylinder 243 which are connected in sequence, the third connecting plate 242 is slidably connected to the positioning frame 21, and the third positioning cylinder 243 is used to drive the third positioning plate 241 to move along the third direction; The connector 100 is provided with a plurality of pins 102 , the positioning frame 21 is provided with through holes 211 for accommodating the pins 102 to pass through, the bottom of the positioning frame 21 is provided with positioning grooves 212 adapted to the third positioning plate 241 , and the third positioning plate 241 is provided with positioning holes 2411 that are plugged and matched with the pins 102 .

[0039] It should be noted that the positioning groove 212 is precisely matched with the third positioning plate 241. Under the drive of the third positioning cylinder 243, the third positioning plate 241 moves along the third direction, and the pin 102 of the connector 100 is inserted into the positioning hole 2411, so that the entire plug-in process has a good positioning support foundation, ensuring that the pin 102 does not deviate or deform during the docking process of the test head 32, thereby improving the test accuracy and stability. The first positioning member 22, the second positioning member 23 and the third positioning member 24 form a complete multi-faceted positioning system, which jointly constrains the top surface, the bottom surface, the two side surfaces and a side surface away from the test head 32 of the connector 100, and realizes all-round and high-precision clamping during the test process, improves the mechanical matching accuracy and operation stability of the entire system, and optimizes the coordination accuracy of the overall positioning system. The third positioning plate 241 is driven to be precisely positioned by the third positioning cylinder 243, avoiding mechanical stress damage to the pin 102 caused by excessive clamping force or uneven pressure, ensuring the structural integrity of the connector 100 and extending its service life.

[0040] like Figures 1 to 3 As shown, the material moving assembly 10 includes a material moving frame 11, the material moving frame 11 is slidably connected to a material moving platform 12, and a first material moving cylinder 13 for driving the material moving platform 12 to move along a first direction is installed on the material moving frame 11; The material transfer platform 12 is slidably connected to a material transfer plate 14, a second material transfer cylinder 15 for driving the material transfer plate 14 to move along a second direction is installed on the material transfer platform 12, and at least one first material transfer head 16 for vacuum adsorption connector 100 is installed on the material transfer plate 14, and the first direction and the second direction are perpendicular to each other. In this embodiment, the material transfer frame 11 is fixedly installed on the test housing 40.

[0041] It should be noted that the first material moving cylinder 13 drives the material moving platform 12 to move along the first direction, and the second material moving cylinder 15 drives the material moving plate 14 to move along the second direction, driving the first material moving head 16 to adsorb and load materials, and test positioning is performed through the positioning component 20, which improves the automation level of the entire system, reduces the need for manual intervention, enables the connector 100 to be accurately and quickly loaded and positioned, improves the test efficiency of the test system, and can continuously handle large quantities of connector 100 test tasks. Due to the vacuum adsorption function of the first material moving head 16, the material moving component 10 can adapt to connectors 100 of various models and specifications, avoiding the limitation that traditional test equipment can only adapt to a certain model of connector 100, and has good flexibility and adaptability.

[0042] like Figures 1 to 3As shown, the material transfer plate 14 is provided with a first mounting position 141 and a second mounting position 142 at intervals, the first mounting position 141 is provided with at least two first material transfer heads 16, and the second mounting position 142 is provided with at least two second material transfer heads 17, and the second material transfer heads 17 are used for vacuum adsorption of the connector 100 after the test. In this embodiment, the first material transfer head 16 and the second material transfer head 17 are both connected to vacuum equipment known in the art, which will not be described in detail herein.

[0043] It should be noted that, by providing a plurality of first material transfer heads 16 and a plurality of second material transfer heads 17, the material transfer assembly 10 can adapt to the loading and unloading tasks of connectors 100 of different models. The first material transfer head 16 is responsible for adsorbing and conveying the connector 100 to be tested to the positioning assembly 20, and the second material transfer head 17 is responsible for adsorbing and removing the connector 100 after the test is completed; this flexible configuration can easily cope with the rapid conversion of connectors 100 of different batches and types, and increases the adaptability and versatility of the system. By automatically controlling the adsorption and conveying process of the first material transfer head 16 and the second material transfer head 17, the automation level of the overall test system is significantly improved, and the need for manual intervention is reduced. At the same time, due to the reasonable and stable configuration of the equipment, the reliability and durability of the entire system are enhanced, and it is suitable for large-scale batch production scenarios.
