[0003] However, most existing tests rely on manual connection of electrical testing equipment to connectors, resulting in low testing efficiency. Therefore, improving the efficiency of connector testing is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0013] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0014] Example: A connector electrical testing device, such as Figure 1 As shown, it includes an electrical testing mechanism 1 and a turntable mechanism 3 for conveying connector 2. The electrical testing mechanism 1 includes an upper electrical testing module 11 and a lower electrical testing module 12. The lower electrical testing module 12 is fixed to the workbench 4, and the upper electrical testing module 11 is fixed to the fixed disk 41. The fixed disk 41 is fixed to the workbench 4. The upper electrical testing module 11 and the lower electrical testing module 12 are located above and below connector 2, respectively. like Figure 3 As shown, the power-on testing module 11 includes several upper probes 111, a mounting plate 112, a power-on testing lifting seat 113, and a power-on testing lifting cylinder 114 that drives the upper probes 111 to descend. The several upper probes 111 are mounted on the mounting plate 112, the mounting plate 112 is mounted on the power-on testing lifting seat 113, the power-on testing lifting seat 113 is connected to the power-on testing lifting cylinder 114, and the power-on testing lifting cylinder is fixed to the fixed plate 41. The lower electrical testing module 12 includes several lower testing probes 121, a lower electrical testing lifting seat 122, and a lower electrical testing lifting cylinder 123 for driving the lower testing probes 121 to lift. The several lower testing probes 121 are installed on the lower electrical testing lifting seat 122, the lower electrical testing lifting seat 122 is connected to the lower electrical testing lifting cylinder 123, and the lower electrical testing lifting cylinder 123 is fixed to the worktable 4. like Figure 8 As shown, the connector 2 is equipped with a plurality of PIN pins 21, the upper and lower ends of the plurality of PIN pins 21 being exposed on the upper and lower surfaces of the connector 2, and the plurality of upper test pins 111 and the plurality of lower test pins 121 corresponding to the plurality of PIN pins 21 respectively.

[0015] like Figure 5-6 As shown, it also includes a locking component 13, which includes an upper fixing block 131, a lower fixing block 132, and a rotating column 133. The rotating column 133 is rotatably connected to the upper fixing block 131. The upper fixing block 131 is fixed to the mounting plate 112.

[0016] In specific implementation, the upper fixing block is provided with a limiting groove 1311, and the rotating column is provided with a limiting post 1333. The limiting post is located inside the limiting groove to limit the rotation angle of the rotating column. In this embodiment, the rotating column rotates 90° after being limited, and the two positions are the locked and unlocked states, respectively. When changing products, since the positions of the pins on the lower surface of different connector products remain unchanged, the lower test pins do not need to be replaced. However, the positions of the pins on the upper surface of different connector products vary, so only the upper test pins need to be replaced. This application includes mounting plates in the power-on test module, with each mounting plate mounting upper test pins at different positions. The positions of the upper test pins differ between different mounting plates to accommodate different connector products. Figure 5 As shown, each mounting plate is provided with an identification block 1121, and the position of the identification block on each mounting plate is different. The power-on lifting seat is provided with several sensors 1131, which identify the identification block.

[0017] like Figure 8 As shown, the connector 2 has a mounting hole, and a steel ring 22 is installed inside the mounting hole, such as... Figure 7As shown, the mounting plate 112 is provided with a detection structure for detecting the steel ring 22. The detection structure includes a detection rod 141, a sleeve 142, and a compression spring 143. The upper end of the detection rod 141 extends to form a connecting rod 1411. The cross-section of the connecting rod 1411 is smaller than that of the detection rod 141. The upper end of the connecting rod 1411 passes through the sleeve 142 and is fixed to the gasket 144. The connecting rod 1411 is fitted with the compression spring 143. The compression spring 143 is located between the top surface of the detection rod 141 and the sleeve 142 so that the detection rod 141 can press against the steel ring 22. The sleeve 142 is fixed to the mounting plate 112. An optical fiber sensor 145 for detecting the position of the gasket 144 is provided above the gasket 144. The optical fiber sensor 145 is mounted on the mounting plate 112.

[0018] like Figure 4 As shown, the upper electric measuring lifting seat 113 is provided with a plurality of second limiting blocks 1132, and the mounting plate 112 is located between the plurality of second limiting blocks 1132.

[0019] In this embodiment, there are four second limiting blocks, and the four second limiting blocks are respectively located at the four corners of the mounting plate; the mounting plate is equipped with a handle 1122; like Figure 2 As shown, the turntable mechanism 3 includes a rotating disk 31, a plurality of carriers 32 for placing connectors 2, and a turntable drive motor 33 for driving the rotating disk 31 to rotate. The plurality of carriers 32 are evenly distributed along the circumference of the rotating disk 31, and the carriers 32 are fixed to the rotating disk 31. The rotating disk 31 is mounted on the turntable drive motor 33, and the turntable drive motor 33 is fixed to the worktable 4.

[0021] In practice, the turntable drive motor, the upper electric lifting cylinder, the fiber optic sensor, the sensor, the upper probe, the lower electric lifting cylinder, and the lower probe are all electrically connected to the controller.

[0022] The working principle of this utility model is as follows: The connector is placed on the carrier, so that the connector is located between the first limiting blocks and supported by the support column. The turntable drive motor drives the rotating disk to rotate, and the connector is transported between the upper electrical test module and the lower electrical test module. The upper test lifting cylinder drives the upper test lifting seat to descend. When the test rod contacts the steel ring, the test rod rises relative to the upper test lifting seat. The fiber optic sensor detects whether the test rod has risen to determine whether the steel ring in the connector's mounting hole is properly installed. The upper test pin contacts the connector's PIN pin. The lower test lifting cylinder drives the lower test lifting seat to rise, and the lower test pin contacts the connector's PIN pin, thereby performing open circuit and high voltage withstand tests on the connector, improving testing efficiency and automation. After the test is completed, the turntable drive motor drives the rotary table to rotate, and the tested connector is removed manually or by a robotic arm.
