[0025] See the instructions attached Figure 3 、 Figure 5 and Figure 6 As shown, the rotating motor 601 serves as a power source, providing rotational power. Its speed and other parameters can be controlled by the digital display control panel 102. It is the starting power for the movement of the entire eccentric connecting rod drive mechanism. The reducer 602 is connected between the output shaft of the rotating motor 601 and the turntable 603. It reduces the speed output by the rotating motor 601 and increases the torque at the same time, so that the turntable 603 can obtain the appropriate speed and torque for stable operation. The turntable 603 rotates under the drive of the reducer 602. Its eccentric position provides a rotation connection point for the connecting rod 604. Through its own rotation, the circular motion of the connecting rod 604 is converted into the swinging motion of the connecting rod 604. One end of the connecting rod 604 is rotationally connected to the eccentric position of the turntable 603, and the other end is rotationally connected to the end of the drive shaft 605. It converts the circular motion of the turntable 603 into the linear reciprocating motion of the drive shaft 605, realizing the drive of the clamping structure 7.

[0026] Driven by the connecting rod 604 , the driving shaft 605 performs linear reciprocating motion, pushing the clamping structure 7 in the test cavity 105 to move, simulating the plugging and unplugging action of the electrical connector.

[0027] The pressure sensor 606 is installed at one end of the drive shaft 605 near the connecting rod 604 to detect in real time the force applied to the drive shaft 605 when pushing the clamping structure 7, i.e., the plugging and unplugging force of the electrical connector, and feeds back the data to the digital display control panel 102.

[0028] The vibration motor 608 is arranged at one end of the drive shaft 605 near the clamping structure 7. It can be turned on or off according to the instructions of the digital display control panel 102, and generates vibration when working to simulate the vibration environment that the electrical connector joint may be subjected to in actual working conditions, so as to more comprehensively test its performance.

[0029] The digital display control panel 102 controls the operation of the rotating motor 601 and the vibration motor 608, receives the data fed back by the pressure sensor 606, and displays and processes the data to monitor the operation status of the entire eccentric connecting rod drive mechanism and adjust its parameters.

[0030] See the instructions attached Figure 3 、 Figure 4 and Figure 6 As shown, the deflection adjustment structure 2 includes an eccentric rotating rod 201. One end of the eccentric rotating rod 201 is rotatably connected to the upper side of the test bench 1 via an eccentric shaft 202, and the other end is bolted to a suspension rod 209. By rotating about the eccentric shaft 202, the position of the suspension rod 209 and the guide cylinder 607 is changed, thereby achieving deflection adjustment of the driving head end position of the drive shaft 605.

[0031] The eccentric shaft 202 serves as the rotation support point of the eccentric rotating rod 201, and its rotation axis is collinear with the rotation axis of the turntable 603, ensuring that the rotation of the eccentric rotating rod 201 is correlated and coordinated with the movement of the entire driving mechanism.

[0032] The suspension rod 209 connects the eccentric rotating rod 201 and the guide cylinder 607, and transmits the rotational displacement of the eccentric rotating rod 201 to the guide cylinder 607. The guide cylinder 607 is slidably connected to the drive shaft 605, providing guidance for the drive shaft 605, so that the guide cylinder 607 can move with the rotation of the eccentric rotating rod 201.

[0033] The arc-shaped slide groove 211 is provided on the top side of the test bench 1 to provide guidance and define a trajectory for the movement of the suspension rod 209 , thereby ensuring that the suspension rod 209 can move along a predetermined trajectory when the eccentric rotating rod 201 rotates.

[0034] The support tubes 205 are symmetrically arranged on both sides of the eccentric rotating rod 201 close to one end of the suspension rod 209 to provide installation support for the adjusting screw 203 so that it can stably work with the eccentric rotating rod 201.

[0035] The adjusting screw 203 is threadedly connected to the support tube 205 , and can be moved in the support tube 205 by rotating the knob 204 , thereby pushing or pulling the eccentric rotating rod 201 , thereby achieving precise adjustment of the deflection angle of the eccentric rotating rod 201 .

[0036] The knob 204 is arranged at the end of the adjusting screw 203 away from the eccentric rotating rod 201, which is convenient for the operator to manually rotate the adjusting screw 203 and is the execution component of the adjustment operation.

[0037] The abutment is located at one end of the adjusting screw 203 close to the eccentric rotating rod 201 and is in the shape of a hemisphere. It contacts the eccentric rotating rod 201 and can better transmit force when the adjusting screw 203 moves, while reducing friction and wear.

[0038] The compression spring 208 is sleeved on the outer side of the end of the adjusting screw 203 close to the eccentric rotating rod 201, providing elastic force so that the indicator needle 207 and the pressure block 210 can always maintain contact with the eccentric rotating rod 201 and the adjusting screw 203, and at the same time can buffer the impact force during the adjustment process.

[0039] The indicator needle 207 is rotatably sleeved on the outside of the adjusting screw 203, and the length mark 212 is set on the upper surface of the test bench 1. Under the action of the compression spring 208, it cooperates with the length mark 212 on the upper surface of the test bench 1 to indicate the adjustment position of the adjusting screw 203, which is convenient for the operator to intuitively understand the deflection degree of the eccentric rotating rod 201.

[0040] The pressing block 210 is connected to one end of the compression spring 208 and is pressed against the eccentric rotating rod 201 under the action of the compression spring 208 to assist in transmitting the force of the adjusting screw 203 and ensure the stability of the adjustment.

[0041] The set bolt 206 is threadedly connected to the support tube 205. When the adjusting screw 203 is adjusted to a suitable position, tightening the set bolt 206 can fix the adjusting screw 203 to prevent it from loosening and shifting during the operation of the equipment.

[0042] See the instructions attached Figure 3 、 Figure 6 and Figure 7As shown, a lifting slide 402 is fixedly provided on one side of the box cover 4, and the lifting slide 402 is set to slide up and down in the gap formed between the test liquid storage box 3 and the cleaning liquid storage box 5. A first electric telescopic rod 403 is provided on the lifting slide 402 for driving it to move up and down, and the push rod head end of the first electric telescopic rod 403 is fixedly connected to the test bench 1. Two first guide rods 404 symmetrically distributed with it as the center are provided on both sides of the first electric telescopic rod 403, and one end of the two first guide rods 404 is fixedly set on the test bench 1, and the upper end of the first guide rod 404 is slidably connected to the guide slide hole 405 opened at the corresponding position of the lifting slide 402, and the output end of the digital display control panel 102 is electrically connected to the input end of the first electric telescopic rod 403. The liquid guide spray assembly includes several first liquid guide tubes 406 respectively arranged in the test liquid storage tank 3 and the cleaning liquid storage tank 5. The bottom of the test liquid storage tank 3 and the cleaning liquid storage tank 5 are respectively provided with liquid pumps for connecting to the first liquid guide tubes 406. The upper ends of the first liquid guide tubes 406 are connected to each other with connecting transverse tubes 410. A second solenoid valve 408 is provided at the connection between the first liquid guide tubes 406 and the connecting transverse tube 410. A spray head 409 is provided on the top side of the box cover 4. The spray head 409 is connected to the connecting transverse tube 410 through the second liquid guide tube 407. The output end of the digital display control panel 102 is electrically connected to the second solenoid valve 408 and the input end of the liquid pump, respectively. The box cover 4 is smoothly raised and lowered by the first electric telescopic rod 403, the lifting slide 402, the first guide rod 404, the guide slide hole 405 and other structures to close or open the test chamber 105; the liquid guide spraying assembly composed of the first liquid guide pipe 406, the liquid pump, the connecting cross pipe 410, the second solenoid valve 408, the second liquid guide pipe 407, the spray head 409 and other components is controlled by the digital display control panel 102 to achieve on-demand spraying of the test liquid or the cleaning liquid to meet the testing and cleaning requirements before and after the test of the electrical connector joint.

[0043] The test liquid storage box 3 is provided with a partition for dividing the interior into several sub-chambers. The upper side of each sub-chamber is connected to a liquid addition pipe 301, and the lower side of each sub-chamber is connected to a liquid discharge pipe 303. Each liquid discharge pipe 303 is provided with a first solenoid valve 304, and the output end of the digital display control panel 102 is electrically connected to the input end of the first solenoid valve 304.

[0044] See the instructions attached Figure 7 and Figure 8As shown, the clamping structure 7 includes a clamping base plate 701, on which two fixed clamping jaws 702 are arranged opposite each other. A movable clamping jaw 703 is provided on the opposite side of the two fixed clamping jaws 702. An adjusting bolt 704 for driving the movable clamping jaw 703 to move is threadedly connected to the fixed clamping jaw 702. Two second guide rods 705 are symmetrically distributed around the adjusting bolt 704. One end of the two second guide rods 705 is fixedly connected to the movable clamping jaw 703, and the other end of the two second guide rods 705 slides through the guide through-holes provided at the corresponding positions of the fixed clamping jaw 702. In actual application, the clamping structure 7 as a whole is used to fix the electrical connector joint for testing. The clamping base plate 701 provides a mounting base for components such as the fixed clamping jaw 702 and the movable clamping jaw 703. By rotating the adjusting bolt 704, under the guidance of the second guide rod 705, the movable clamping jaw 703 is driven to move relative to the fixed clamping jaw 702, so as to adapt to electrical connector joints of different specifications and firmly clamp them between the fixed clamping jaw 702 and the movable clamping jaw 703, ensuring the stable position of the electrical connector joint during the test and providing a reliable fixing basis for subsequent tests.

[0045] Working principle and technical effects of the present invention: When in use, by rotating the adjusting bolt 704 on the fixed clamping jaw 702 in the clamping structure 7, the movable clamping jaw 703 is driven to move under the guidance of the second guide rod 705, thereby fixing the electrical connector joint and the electrical connector socket respectively between the movable clamping jaws 703 of the two clamping structures 7.

[0046] A rotary motor 601 drives a turntable 603 through a reducer 602. A connecting rod 604, located off-center on the turntable 603, drives a drive shaft 605. This drives a clamping structure 7 on one side, reciprocating within the test chamber 105, simulating the insertion and removal of an electrical connector. A pressure sensor 606 at one end of the drive shaft 605 measures the insertion and removal force in real time and provides feedback to the digital display control panel 102. A vibration motor 608 provides vibration during testing to simulate actual operating conditions.

[0047] By rotating the adjusting screw 203 in the supporting cylinder 205 in the offset adjustment structure 2 and operating the knob 204, the indicator needle 207 indicates the position on the length mark 212 under the action of the compression spring 208, and adjusts the deflection angle of the eccentric rotating rod 201 around the eccentric shaft 202, thereby changing the position of the suspension rod 209 and the guide cylinder 607, realizing the deflection adjustment of the driving head end position of the driving shaft 605, and simulating the test under different offset states.

[0048] The digital display control panel 102 controls the first electric telescopic rod 403, which drives the lifting slide 402 and the box cover 4 up and down under the guidance of the first guide rod 404 to open or close the test chamber 105. The box cover 4 cooperates with the sealing gasket 106 at the opening of the test chamber 105 to ensure sealing.

[0049] The digital control panel 102 controls the liquid pumps within the test liquid storage tank 3 and the cleaning liquid storage tank 5. These pumps deliver liquid through a first liquid conduit 406 to a connecting transverse pipe 410. Liquid is then sprayed through a second liquid conduit 407 from a spray head 409 on the top side of the tank cover 4. The second solenoid valve 408 is controlled to select whether to spray the test liquid or the cleaning liquid. Different test liquids can be added to the chambers separated by partitions within the test liquid storage tank 3 via a liquid addition pipe 301. A first solenoid valve 304 on a liquid discharge pipe 303 controls the discharge of liquid.
