[0002] Connectors, as key components for signal transmission and power connection in electronic devices, are widely used in communications, automotive, and consumer electronics. Connector terminals are their core conductive components, and their electrical properties (such as contact resistance, insulation resistance, and withstand voltage) directly determine the reliability and lifespan of the connector. Therefore, rigorous electrical performance testing of the terminals is an essential quality control step during connector manufacturing.

[0003] Currently, the testing of connector terminals in the industry mainly relies on manual operation.

[0004] This manual inspection method can only process one connector at a time and requires repeated clamping, positioning, and contact probes. For mass production, this is extremely time-consuming and severely restricts the increase in production capacity. Summary of the Invention

[0012] Furthermore, the loading seat includes a horizontal plate, with vertical plates connected to both ends of the horizontal plate. The horizontal plate is inserted into a folding loading plate with a U-shaped structure.

Detailed Implementation

[0019] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] In the electronics manufacturing industry, connectors are key components for signal transmission, and the electrical performance and connection reliability of their terminals are of paramount importance. Current terminal testing methods mostly involve manual, one-by-one operation, placing individual connectors on a fixture and then manually or semi-automatically bringing test probes into contact with the terminals. This method is not only inefficient but also labor-intensive.

[0021] The present invention provides a connector terminal testing device, which aims to solve the above-mentioned problems. The overall technical concept is as follows: multiple connectors 100 are fixed at one time by a folding loading plate 2, and the folding loading plate 2 is installed on a horizontally movable loading seat 1 after being folded into a U-shape. Then, a pair of pins 10 that can move back and forth are used to sequentially insert into the connector terminals of each connector for electrical performance testing, thereby realizing a batch and automated testing process.

[0022] Example 1: like Figures 1 to 4 As shown, a connector terminal testing device includes a folding loading plate 2 for fixing two connector terminals at both ends of a connector 100. Multiple connectors 100 are fixed on the folding loading plate 2 to achieve batch testing. The folding loading plate 2 is folded into a U-shaped structure and assembled on a loading seat 1. The loading seat 1 is driven to move horizontally. A pair of pin headers 10, which can move forward and backward horizontally, are positioned opposite the loading seat 1, and an electrical connection tester 101 for the pin headers 10 is installed.

[0023] Its working principle is as follows: First, the connector terminals at both ends of multiple connectors 100 are fixed on the folding loading plate 2 respectively; then the folding loading plate 2 is folded into a U-shape and inserted into the loading seat 1; during testing, the loading seat 1 drives all the connectors 100 on it to move horizontally. When a connector 100 moves to a position directly opposite the pin header 10, the loading seat 1 stops; then, a pair of pin headers 10 extend forward and are inserted into the connector terminals at both ends of the connector 100 respectively, and the tester 101 begins to perform electrical performance testing; after the test is completed, the pin headers 10 retract, the loading seat 1 continues to move, and then the next connector 100 is tested; this process is repeated until all connectors 100 are tested.

[0024] It should be emphasized that the core improvement of this embodiment lies in the use of a foldable loading plate 2 to fix multiple connectors 100 at once, and the realization of automated assembly line testing of multiple connector terminals through the horizontal movement of the loading seat 1 and the back-and-forth movement of the pin header 10. Compared with the traditional manual single-piece testing method, this changes the traditional manual single-piece testing mode, eliminating the need for frequent manual movement and positioning, greatly reducing the labor intensity of operators, and significantly improving testing efficiency.

[0025] Example 2 It is understandable that, in Example 1, as Figure 4-6 The folding loading plate 2 needs to be folded from a flat state into a U-shape to ensure that multiple connectors 100 can be compactly assembled on the loading base 1; based on this, the folding loading plate 2 includes a central plate 20, and mounting plates 21 are pivotally connected to both edges of the central plate 20. The mounting plates 21 are provided with multiple clamping modules 22 for clamping and fixing the connector terminals.

[0026] Because when the folding loading plate 2 is designed to be only U-shaped, it is inconvenient to assemble the two connector terminals at both ends of the connector 100 to the clamping modules 22 of the two mounting plates 21 respectively during use.

[0027] Among them, such as Figure 2-3 The clamping module 22 includes a pair of clamping blocks 230. A guide portion 232 is provided at the bottom of the inner side of the clamping block 230, and a limiting block 231 is provided at the end of the clamping block 230. The end of the limiting block 231 protrudes from the inner side of the clamping block 230. During operation, the connector terminal is forcefully inserted between the two clamping blocks 230. At this time, the two clamping blocks 230 clamp the connector terminal under the action of friction, and the limiting block 231 can act as a positioning element, which can position the installation of the connector terminal.

[0028] It is known that, in order to facilitate the flexible clamping of the connector terminal by the two clamping blocks 230, a rubber clamping layer is provided on the inner wall of the clamping block 230. The rubber clamping layer can deform when the connector terminal is inserted between the two clamping blocks 230, and the resulting deformation generates a squeezing force to flexibly clamp the connector terminal located between the two clamping blocks 230. After the test is completed, the folding loading plate 2 is unfolded to facilitate the manual removal of the connector terminal from between the two clamping blocks 230.

[0029] Meanwhile, how to achieve reliable folding and unfolding of the foldable loading plate 2, such as... Figure 7 Several first protrusions 201 are evenly spaced on both sides of the middle plate 20, and a rectangular groove is formed between two adjacent first protrusions 201; for example Figure 10 A plurality of second protrusions 211 are equally spaced on one side of the mounting plate 21, and a rectangular groove is formed between two adjacent second protrusions 211. The first protrusion 201 is inserted into the rectangular groove, and the second protrusion 211 is inserted into the rectangular groove. The first protrusion 201 and the second protrusion 211 are respectively provided with a circular hole 1 202 and a circular hole 212. The mounting plate 2 also includes a rotating shaft that passes through the circular hole 1 202 and the circular hole 212. The folding and unfolding of the folding loading plate 2 can be easily controlled by the cooperation of the rotating shaft, the circular hole 1 202 and the circular hole 212.

[0030] To ensure the stability of its U-shaped structure in the folded state and its planar stability in the unfolded state, that is, to lock the angle of the mounting plate 21 relative to the intermediate plate 20, two limiting holes 203 are provided on the outer wall surface of each first protrusion 201, and the axial directions of the two limiting holes 203 are perpendicular to each other. Figure 7-9 A blind hole 24 is provided axially within the intermediate plate 20, and an operating rod 25 is movably mounted within the blind hole 24. Movable cavities 26 are provided on both sides of the intermediate plate 20, each with a channel 262 communicating with the blind hole 24 at one end and a guide hole 261 extending through at the other end. A movable plate 265 is movably mounted within the movable cavity 26, and a limiting rod 264 extends through the movable plate 265. Both ends of the limiting rod 264 can slide along the guide hole 261 and the channel 262. A spring 263 is fitted around the limiting rod 264 between the movable plate 265 and one sidewall of the movable cavity 26. A connecting rope 266 connects the two limiting rods 264 on both sides of the operating rod 25, and an opening 251 is provided on the operating rod 25 for the connecting rope 266 to pass through.

[0031] The working process is as follows: When it is necessary to unfold or fold the mounting plate 21, pull the operating lever 25. The operating lever 25 pulls the limiting levers 264 on both sides through the connecting rope 266, overcoming the elastic force of the spring 263, so that the end of the limiting lever 264 exits from the limiting insertion hole 203 and the lock is released; when the mounting plate 21 is rotated to the required position, release the operating lever 25, and the spring 263 pushes the limiting lever 264 into the corresponding limiting insertion hole 203 to achieve locking; specifically, when the end of the limiting lever 264 is inserted into one limiting insertion hole 203, the intermediate plate 20 and the mounting plate 21 are perpendicular; when the end of the limiting lever 264 is inserted into another limiting insertion hole 203, the intermediate plate 20 and the mounting plate 21 are parallel.

[0032] It should be emphasized that the core improvement of this embodiment lies in the linkage locking mechanism composed of the operating rod 25, the connecting rope 266, the spring 263 and the limiting rod 264, which enables the mounting plate 21 to be securely locked in two key positions, vertical and parallel. This ensures the stability of the structure in the U-shaped state during testing and facilitates unfolding the mounting plate 21 into a flat state when the connector 100 is loaded, thus achieving a balance between functionality and convenience.

[0033] Example 3: It is understandable that in Embodiment 1 and Embodiment 2, after the foldable loading plate 2 is folded into a U-shape, it needs to be reliably fixed on the loading seat 1. Furthermore, during the testing process, the connector terminals of the connector 100 also need to be stably pressed to prevent displacement when the pin header 10 is inserted, which would affect the testing results.

[0034] To solve the above-mentioned loading and clamping problems, such as Figure 1-3 As shown, the loading base 1 includes a horizontal plate 10, with vertical plates 11 connected to both ends of the horizontal plate 10. The horizontal plate 10 is inserted into a U-shaped folding loading plate 2. Movable plates 16 are provided on the upper and lower sides of the horizontal plate 10, and the two movable plates 16 abut against the two mounting plates 21 respectively. A first telescopic module is provided at both ends of the vertical plate 11, and a pressure rod 15 is connected to the end of the first telescopic module. In the loaded state, the pressure rod 15 presses against the connector terminal.

[0035] In order to achieve lateral positioning of the mounting plate 21, grooves are provided on both inner walls of the vertical plate 11. A second telescopic module is installed in the groove. The end of the second telescopic module is connected to an abutment block 14, and the end of the abutment block 14 abuts against the end face of the mounting plate 21.

[0036] In order to drive the movable plate 16 to move, so that when the horizontal plate 10 is inserted into the folded loading plate 2 with a U-shaped structure, the two movable plates 16 are driven to abut against the two mounting plates 21 respectively, and a third telescopic module is connected between the horizontal plate 10 and the movable plate 16.

[0037] In addition, a pressure sensor is installed at each of the two ends of the horizontal plate 10 near the folding loading plate 2; it also includes a processor, which is connected to the first telescopic module, the second telescopic module, the third telescopic module and the pressure sensor.

[0038] The working process is as follows: When the folded U-shaped loading plate 2 is placed on the horizontal plate 10, the two pressure sensors detect signals. At this time, the processor controls the third telescopic module to move the movable plate 16 so that it abuts against the mounting plate 21. Then, the processor controls the second telescopic module to move the abutment block 14 against the end face of the mounting plate 21, thereby adjusting the horizontal position of the folded loading plate 2 on the movable plate 16. After adjustment, the processor controls the third telescopic module to move the movable plate 16 up or down so that it abuts tightly against the mounting plate 21. At the same time, the first telescopic module moves to push the pressure rod 15 against the connector terminal of the connector 100, pressing it tightly. Based on this, the position adjustment and fixation of the connector terminal are completed through the above actions.

[0039] It should be emphasized that the core improvement of this embodiment is that the loading seat 1 of the present invention fixes and presses the folding loading plate 2 and the connector 100 on it from multiple dimensions through the synergistic action of the horizontal plate 10, the movable plate 16, the abutment block 14 and the pressure rod 15; combined with the pressure sensor and the processor, it realizes an automated, precise and controllable loading and pressing process, ensuring the stable position of the connector terminal during the detection process, and providing a reliable guarantee for the accurate insertion of the pin header 10.

[0040] Example 4 Based on the connector terminal testing device described above, this embodiment also provides a complete automated testing system; such as Figure 1 As shown, a protrusion 12 is provided at the bottom end of the vertical plate 11, and the bottom end of the protrusion 12 is connected to the base plate 13; the base plate 13 is installed on the movable part of a horizontal displacement mechanism 200; the direction of movement of the horizontal displacement mechanism 200 is perpendicular to the direction of movement of the pin header 10, and the direction of movement of the horizontal displacement mechanism 200 is the same as the length direction of the mounting plate 21; the horizontal displacement mechanism 200 is a linear module.

[0041] In addition, the device includes a marking unit disposed on one side of the pin header 10, used to mark unqualified connectors 100 after testing. The tester 101 can be an insulation resistance tester or a withstand voltage tester, used to test the electrical performance of the connector terminals.

[0042] The complete workflow is as follows: The operator first fixes multiple connectors 100 onto the unfolded folding loading plate 2, then folds it into a U-shape and places it into the loading seat 1; the various telescopic modules of the loading seat 1 automatically activate to fix the folding loading plate 2 and clamp the connector terminals; subsequently, the horizontal displacement mechanism 200 drives the entire loading seat 1 to move stepwise along a direction perpendicular to the pin header 10; at each station, the pin header 10 extends forward to insert the terminal for testing; the tester 101 sends the test results to the controller; if a defective product is detected, the controller will control the marking unit to mark it (e.g., by spraying paint or dotting) when the connector moves to the marking unit position. After all connectors have been tested, the horizontal displacement mechanism 200 resets, the loading seat 1 unlocks, the operator removes the folding loading plate 2, and replaces it with a new folding loading plate for the next round of testing.

[0043] It should be emphasized that the core improvement of this embodiment lies in integrating the foldable loading plate 2, loading seat 1, horizontal displacement mechanism 200, pin header detection module, and marking unit into a complete automated production line. The horizontal displacement mechanism 200 enables continuous inspection of the connector 100, and the marking unit automatically identifies defective products, achieving full automation from loading and inspection to sorting. This significantly improves production efficiency and quality traceability, making it suitable for large-scale production scenarios.

[0044] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
