[0002] Currently, during the testing of cable assemblies, it is usually necessary to electrically connect the connectors to the testing equipment to complete the detection of signals or pathways.

[0003] Current technologies mostly employ manual operation, where operators hold the test probe and insert it into the cable connector. This manual method increases the workload for operators. Summary of the Invention

[0004] The technical problem this invention aims to solve is that, in existing technologies, manual operation is often used, where operators hold the test head and insert it into the cable connector. This manual operation increases the labor intensity of the operators. Therefore, this invention provides a testing mechanism and device.

[0005] To address the aforementioned issues, this utility model provides a testing mechanism for testing cable assemblies. The cable assembly includes a connector and a cable connected to internal terminals of the connector. The testing mechanism includes a test head, a first fixing component, a second fixing component, a test platform, and a driving component. The first fixing component and the second fixing component are mounted on the test bench. The first fixing component is used to fix the connector, and the second fixing component is used to fix the end of the cable away from the connector. The first fixing component and the second fixing component are arranged at intervals along a first direction, and the driving component is connected to the test head. The driving component is used to drive the test head to insert into or pull out of the connector along the first direction.

[0006] Optionally, the first fixing component includes a mounting base, which is mounted on the test bench, and the connector is disposed on the mounting base; The mounting base is provided with a limiting structure, which can limit the displacement of the connector along the first direction.

[0007] Optionally, the top of the mounting base is provided with an accommodating space, which extends through the mounting base along the first direction; The limiting structure is a first limiting groove disposed at the edge of the accommodating space, and the outer peripheral surface of the connector has a protrusion, which engages with the first limiting groove.

[0008] Optionally, the bottom of the connector is disposed in the receiving space, and the top of the connector extends out of the receiving space; The first fixing component further includes a clamping member for clamping the top of the connector to define the position of the connector relative to the mounting base.

[0009] Optionally, the clamping member includes a power unit, a first clamping block, and a second clamping block, wherein the first clamping block and the second clamping block are arranged opposite to each other along a second direction; Along the second direction, the connector is located between the first clamping block and the second clamping block; Both the first clamping block and the second clamping block are connected to the output end of the power unit. The power unit is used to drive the first clamping block and the second clamping block to move closer to each other or further away from each other along the second direction, so that the first clamping block and the second clamping block can clamp the connector; wherein, the first direction is perpendicular to the second direction.

[0010] Optionally, when the cable assembly is fixed by the first fixing component and the second fixing component, the cable is in a straightened state.

[0011] Optionally, the second fixing component includes a base and a plurality of limiting plates, the plurality of limiting plates being arranged at intervals along a second direction on the base, and a second limiting groove corresponding to the cable being formed between two adjacent limiting plates, the cable being limited in the second limiting groove; wherein, the first direction is perpendicular to the second direction.

[0014] According to the testing mechanism provided in this embodiment, the connector of the cable assembly is fixed on a first fixing component, and the end of the cable away from the connector is fixed on a second fixing component, forming a stable test reference. A driving component drives the test head to move along a first direction, ensuring reliable contact between the test head and the internal terminals of the connector, establishing a test circuit, and automatically detecting the cable assembly's path or signal transmission performance. After the test is completed, the driving component automatically pulls the test head out of the connector, completing the entire testing process. Compared to the existing method of manually inserting the test head into the connector, this application, by setting up a first fixing component, a second fixing component, and a driving component, achieves the fixing of both ends of the cable assembly and the automatic insertion and removal of the test head, completely replacing the traditional method of manually inserting the test head. This greatly reduces the labor intensity of operators and avoids fatigue caused by repetitive operations. Simultaneously, through precise positioning via mechanical drive, it ensures that the position and force of the test head and connector are consistent each time they are inserted, effectively reducing poor contact, test result fluctuations, or damage to the connector terminals caused by human factors, thereby significantly improving the automation level, reliability, and consistency of the testing process.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] like Figures 1 to 4 As shown, an embodiment of the present invention provides a testing mechanism for testing a cable assembly 10. The cable assembly 10 includes a connector 101 and a cable 102 connected to the internal terminals of the connector 101. The testing mechanism includes a test head 1, a first fixing component 2, a second fixing component 3, a test table 4, and a driving component. The first fixing component 2 and the second fixing component 3 are installed on the test bench 4. The first fixing component 2 is used to fix the connector 101, and the second fixing component 3 is used to fix the end of the cable 102 away from the connector 101. The first fixing component 2 and the second fixing component 3 are arranged at intervals along a first direction. The driving component is connected to the test head 1 and is used to drive the test head 1 to insert into or remove from the connector 101 along the first direction. The "first direction" refers to the direction of the axis of motion of the test head 1 and the connector 101 during insertion and removal, typically a linear reciprocating motion direction. This direction is consistent with the insertion axis of the connector 101, ensuring that the test head 1 can be accurately and smoothly inserted into the connector 101, forming good electrical contact with the internal terminals and avoiding terminal damage or contact failure due to misaligned insertion or removal. In this embodiment, the first direction is... Figure 1 The X direction in the process. It is understood that the cable assembly 10 (including connector 101 and cable 102) and test head 1 in this application are existing common components, and the multimeter, display module 6, and other circuit detection and display units used for testing are also existing technologies. This utility model does not improve the circuit itself; its innovation lies mainly in the optimization of the structural design. Specifically, through the coordinated cooperation of the first fixing component 2, the second fixing component 3, and the driving component, an automated and precisely positioned testing mechanism is constructed, realizing the automatic insertion, removal, and positioning of the test head 1 on the connector 101, solving the problems of low efficiency, high labor intensity, and poor consistency caused by manual operation. During the test, the test head 1 is electrically connected to an external multimeter, which in turn is electrically connected to the display module 6 (such as a display screen). The connector 101 of the cable assembly 10 has an existing temperature-sensitive resistor (not a new structure added in this application). When the driving component drives the test head 1 to insert into the connector 101 along the first direction, the terminals inside the test head 1 and connector 101 become conductive, thus forming an electrical connection with the temperature-sensitive resistor. At this time, the multimeter applies a test signal to the temperature-sensitive resistor through test head 1, measures its resistance value, and transmits the measured resistance data to the display module 6 for real-time display. By judging whether the resistance value is within the normal range, it can be determined whether the circuit status of the cable assembly 10 is normal, thereby completing the performance test of the cable assembly 10. This utility model reliably positions both ends of the cable assembly 10 by setting the first fixing component 2 and the second fixing component 3, and automatically drives the test head 1 to insert or pull out the connector 101 in the first direction by the drive component, effectively replacing the traditional manual hand-held operation of inserting and removing the test head 1. This significantly reduces the labor intensity of operators, avoids mistests or poor contact caused by uneven force or improper insertion, and improves the consistency and reliability of the test. At the same time, the automated insertion process improves the testing efficiency, is suitable for rapid testing in a mass production environment, and helps to improve the overall production cycle and product yield.

[0023] like Figures 1-3 As shown, in one embodiment, the first fixing component 2 includes a mounting base 21, which is mounted on the test bench 4, and the connector 101 is disposed on the mounting base 21; Mounting base 21 is provided with a limiting structure 211, which can limit the displacement of connector 101 along the first direction. By setting the limiting structure 211 on mounting base 21, the position of connector 101 in the first direction can be precisely limited, ensuring that connector 101 remains stable and does not undergo axial displacement during testing. This improves the alignment accuracy when connector 101 is inserted into test head 1, avoiding insertion failure or poor contact due to connector 101 retraction or positional misalignment, and effectively protecting the internal terminals of connector 101 from overstress damage. At the same time, the setting of limiting structure 211 enhances the repeatability and consistency of the testing process, further improving the reliability of test results and providing structural guarantee for achieving automated, high-precision testing.

[0024] like Figure 3 As shown, in one embodiment, a receiving space 212 is provided on the top of the mounting base 21, and the receiving space 212 extends through the mounting base 21 along a first direction; The limiting structure 211 is a first limiting groove located at the edge of the accommodating space 212. The outer peripheral surface of the connector 101 has a protrusion 1011, which engages with the first limiting groove. By providing an accommodating space 212 extending along the first direction at the top of the mounting base 21 and providing a first limiting groove at the edge of the accommodating space 212, the connector 101 is engaged and positioned by the protrusion 1011 on its outer peripheral surface, effectively limiting the axial displacement and circumferential rotation of the connector 101 in the first direction. When the connector 101 is inserted into the accommodating space 212 and the protrusion 1011 engages with the first limiting groove, its position is firmly fixed, ensuring that the connector 101 will not retract or shift during the insertion of the test head 1, thus improving the stability and reliability of the insertion. The protrusion 1011 on the connector 101 can be an existing structural feature of the connector itself, such as a boss or fixing lug on an existing connector used for screw mounting. This utility model utilizes the existing structure as a positioning protrusion 1011, which engages with the first limiting groove on the mounting base 21 to achieve axial and circumferential limiting of the connector 101. No additional processing or modification of the connector 101 itself is required, fully utilizing the inherent structure of existing components, reducing the design complexity and manufacturing cost of the fixture, while improving adaptability and versatility, demonstrating the rationality and practicality of the structural design of this application.

[0025] like Figure 2 and Figure 3 As shown, in one embodiment, the bottom of the connector 101 is disposed in the receiving space 212, and the top of the connector 101 extends out of the receiving space 212; The first fixing component 2 also includes a clamping member 22, which is used to clamp the top of the connector 101 to limit the position of the connector 101 relative to the mounting base 21. The bottom of the connector 101 is placed within the receiving space 212 of the mounting base 21, and the top protrudes, working with the clamping member 22 to clamp and fix the top of the connector 101, forming a double positioning and constraint from top to bottom. The receiving space 212 and the limiting structure 211 achieve axial and circumferential limiting of the lower part of the connector 101. At the same time, the clamping member 22 enhances the pressing effect on the upper part of the connector 101, effectively preventing the connector 101 from loosening, moving upward or vibrating due to the insertion force of the test head 1 during the test, further improving the fixing stability of the connector 101.

[0026] like Figure 2 As shown, in one embodiment, the clamping member 22 includes a power unit, a first clamping block 221 and a second clamping block 222, the first clamping block 221 and the second clamping block 222 being arranged opposite to each other along a second direction; Along the second direction, the connector 101 is located between the first clamping block 221 and the second clamping block 222; Both the first clamping block 221 and the second clamping block 222 are connected to the output end of the power unit. The power unit drives the first clamping block 221 and the second clamping block 222 to move closer or further apart along a second direction, so that the first clamping block 221 and the second clamping block 222 can clamp the connector 101; wherein, the first direction is perpendicular to the second direction. By using the power unit to drive the two clamping blocks closer together along the second direction, automatic clamping of the top of the connector 101 is achieved; after the test, the clamping blocks move further apart, achieving automatic release, facilitating workpiece replacement. This design automates the clamping action without manual intervention, improving the integration and operational efficiency of the testing process. The first clamping block 221 and the second clamping block 222 clamp the connector 101 from opposite sides, with symmetrical force, stable and reliable clamping, effectively preventing the connector 101 from shifting or loosening during the test, ensuring the accuracy and safety of the test head 1 insertion process. The power unit can be a clamping cylinder. In this embodiment, the second direction is... Figure 1 The Y-direction in the middle.

[0027] like Figure 1 As shown, in one embodiment, when the cable assembly 10 is fixed by the first fixing component 2 and the second fixing component 3, the cable 102 is in a straightened state. When the cable assembly 10 is simultaneously fixed by the first fixing component 2 and the second fixing component 3, the cable 102 is in a straightened state, which can effectively eliminate the shaking or positional displacement of the cable 102 caused by bending or slack. The tensioning arrangement ensures the stability of the cable assembly 10 during the test and prevents the alignment accuracy and contact reliability between the connector 101 and the test head 1 from being affected by the swinging of the cable 102.

[0028] like Figure 4 As shown, in one embodiment, the second fixing component 3 includes a base 31 and a plurality of limiting plates 32. The plurality of limiting plates 32 are arranged at intervals along a second direction on the base 31. A second limiting groove 33 corresponding to the cable 102 is formed between two adjacent limiting plates 32, and the cable 102 is limited in the second limiting groove 33; wherein, the first direction is perpendicular to the second direction. The second limiting groove 33 can effectively constrain the position of the cable 102 in the lateral direction (second direction), prevent the cable 102 from swinging or shifting left and right during the test, ensure that the cable assembly 10 remains straight, and improve the test stability. It is understood that the cable assembly 10 may include a plurality of parallel cables 102, such as those commonly found in multi-channel or multi-functional cable harnesses. The plurality of second limiting grooves 33 formed between the plurality of limiting plates 32 can accommodate different cables 102 one by one, realizing independent and precise positioning of multiple cables 102. This design not only adapts to the testing needs of multi-cable 102 products but also ensures that each cable 102 is in a taut and fixed state, avoiding tangling or interference, significantly improving testing reliability and operational efficiency. Simultaneously, by adjusting the spacing of the limiting plates 32 or replacing different sets of limiting plates 32, it can accommodate products with different numbers and arrangements of cables 102, enhancing the versatility and flexible production capabilities of the testing mechanism. Furthermore, the base 31 has multiple mounting holes, allowing the limiting plates 32 to be fixed by selecting different mounting holes, thereby adjusting the distance between adjacent limiting plates 32 and changing the width of the second limiting groove 33. This design can accommodate cables 102 of different diameters or spacings, improving the versatility and flexibility of the tooling, meeting the testing needs of multiple cable assemblies 10, reducing fixture change frequency, and increasing production efficiency.

[0029] like Figure 1 As shown, in one embodiment, the test bench 4 is provided with a guide rail 5, which extends along a first direction, and the test head 1 is slidably connected to the guide rail 5. The test head 1 slides along the first direction via the guide rail 5, ensuring that the movement trajectory of the test head 1 during the insertion and removal of the connector 101 is straight and stable, improving the accuracy of alignment with the connector 101 and the reliability of the insertion, while reducing the wear of the test head 1 and the connector 101 caused by the off-center motion, and improving the test repeatability and the durability of the mechanism.

[0030] In one embodiment, the driving component is a cylinder, with the cylinder body fixed to the test bench 4 and the piston rod connected to the test head 1. Using a cylinder as the driving component results in a simple structure and stable operation. The piston rod pushes the test head 1 along the guide rail 5 to accurately complete the insertion and extraction actions, thereby automating the testing process and improving operational efficiency and repeatability.

[0031] According to the testing mechanism provided in this embodiment of the present invention, the connector 101 of the cable assembly 10 is fixed on the first fixing component 2, and the end of the cable 102 away from the connector 101 is fixed on the second fixing component 3, forming a stable test reference. The driving component drives the test head 1 to move along the first direction, so that the test head 1 reliably contacts the internal terminals of the connector 101, establishing a test circuit and realizing automatic detection of the path or signal transmission performance of the cable assembly 10. After the test is completed, the driving component automatically pulls the test head 1 out of the connector 101, completing the entire test process. Compared with the existing technology of manually inserting the test head 1 into the connector 101, this application, by setting the first fixing component 2, the second fixing component 3, and the driving component, realizes the fixing of both ends of the cable assembly 10 and the automatic insertion and removal of the test head 1, completely replacing the traditional method of manually inserting and removing the test head 1. This greatly reduces the labor intensity of operators and avoids fatigue caused by repetitive operations. Meanwhile, the precise positioning driven by the mechanical drive ensures that the position and force of the test head 1 and the connector 101 are consistent each time they are inserted, effectively reducing poor contact, fluctuations in test results, or damage to the terminals of the connector 101 caused by human factors, thereby significantly improving the automation level, reliability, and consistency of the testing process.

[0032] In addition, this utility model embodiment provides a testing device, including a multimeter and the testing mechanism of the above embodiment. The test bench 4 is provided with a display module 6, and the multimeter is electrically connected between the test head 1 and the display module 6.

[0033] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
