[0026] Referring to Figures 1-4 The waterproof performance testing device for the automobile wire harness connector provided in the embodiment includes a fixed plate 1 and inflation equipment 2. The inflation equipment 2 is an external air supply device and is transmitted through an inflation pipe 4. One side of the fixed plate 1 is fixedly connected with a storage seat 3. One side of the inflation equipment 2 is uniformly fixedly connected with the inflation pipe 4. One end of the inflation pipe 4 is fixedly connected with a connecting pipe 5. The storage seat 3 is provided with a clamping groove 6. The clamping groove 6 is in contact with the connecting pipe 5. One side of the storage seat 3 is provided with a wire slot 7. The wire slot 7 is used for placing the connecting pipe 5. One side of the storage seat 3 located in the wire slot 7 is provided with a prism groove 8. The prism groove 8 is used for placing the wire harness of the connector to be detected. One side of the wire slot 7 close to the prism groove 8 is fixedly connected with a clamping block 27. Through the clamping block 27, the wire harness can pass through and the prism rubber column 16 is limited. The upper end of the storage seat 3 is fixedly connected with a first support. The upper end of the first support is fixedly connected with a connecting plate 9. One side of the upper end of the connecting plate 9 is fixedly connected with a first motor. The first motor drives a first screw 10 to rotate, so that a pressing plate 11 contacts the storage seat 3, thereby making the storage seat 3 closed. The pressing plate 11 is provided with a structure corresponding to the storage seat 3. The output end of the first motor is fixedly connected with the first screw 10. One end of the first screw 10 is rotatably connected with the storage seat 3. The first screw 10 is threadedly connected with the pressing plate 11. The pressing plate 11 corresponds to the storage seat 3.

[0027] The storage seat 3 is provided with a storage groove 12, and the bottom side of the storage groove 12 is fixedly connected with a spring rod 13. The spring rod 13 can provide flexible support for a piston plate 14. The upper end of the spring rod 13 is fixedly connected with the piston plate 14. The piston plate 14 is in contact with the storage groove 12. The storage groove 12 is fixedly connected with a blocking strip 31 (the piston plate 14 contacts the blocking strip 31, which is the zero scale of the distance sensor 30). The upper and lower sides of the blocking strip 31 are fixedly connected with a blocking block 32. The storage groove 12 is fixedly connected with a distance sensor 30. The distance sensor 30 monitors the position of the piston plate 14. When the distance between the two piston plates 14 is far away, the distance sensor 30 can monitor and provide signal transmission, and the signal is transmitted to a display screen 15. The display screen 15 is fixedly connected to the display screen 15 through a wire in series connection. The display screen 15 is fixedly connected to the display screen 15.

[0028] The prism groove 8 is inserted with a prism rubber column 16 on one side, and the prism rubber column 16 is in contact with the prism groove 8. The prism rubber column 16 is in a split structure and is in a rubber structure. Through the extrusion of external force, the prism rubber column 16 enters the prism groove 8.

[0029] The storage seat 3 is fixedly connected with a second support on one side close to the prism groove 8. The second support is fixedly connected with a vertical plate 19 on one side. The vertical plate 19 is fixedly connected with a second motor at one end. The second motor is fixedly connected with a second screw rod 20 at the output end. The second screw rod 20 is threadedly connected with a push plate 21. The second motor drives the second screw rod 20 to rotate, which can extrude the push plate 11 on one side of the prism rubber column 16, so that the prism rubber column 16 is extruded by the double extrusion of the wire harness and the prism groove 8, and the sealing effect is achieved. The sealing between the wire harness on one side of the plug under test and the storage seat 3 is improved.

[0030] The push plate 21 is provided with a recess 22 away from the vertical plate 19 on one side. The recess 22 corresponds to the prism rubber column 16. By setting the recess 22, one end of the prism rubber column 16 can be connected, so that the extrusion effect of the prism rubber column 16 on the wire harness is better.

[0031] The prism rubber column 16 is provided with a restraint hole 17 on one side. The caliber of the restraint hole 17 gradually decreases from the vertical plate 19 to the storage seat 3. By setting the restraint hole 17, the adaptability to wire harnesses with different diameters can be improved.

[0032] Working principle: start the first motor and cause the first screw 10 to rotate, and make the pressure plate 11 and the storage seat 3 a split structure, then put one side of the inflation tube 4 into the card slot 6, the rubber gasket 25 on the connecting tube 5 is between the two snap rings 26 and the rubber gasket 25 is in contact with the arc block 24, and at the same time connect the connecting ring 5 with the plug to be inspected, the plug to be inspected and the excess wiring harness are located on the upper side of the baffle 31, and at the same time, one side of the wiring harness of the plug to be inspected is placed in the wire groove 7, and then the wiring harness is wrapped with the prism rubber column 16, and then the prism rubber column 16 is snapped into the prism groove 8, at this time the pressure plate 11 moves down, and the space between the pressure plate 11 and the storage seat 3 is closed, the rubber gasket 25 is squeezed and the prism The prism rubber column 16 is also squeezed to a certain extent, and then the second motor is started to drive the second screw 20 to rotate, and then the push plate 21 and the recess 22 are connected with one side of the prism rubber column 16. One side of the prism rubber column 16 is squeezed and gradually inserted into the prism groove 8. At this time, the prism rubber column 16 is squeezed by the push plate 21, the squeezing ball 28 and the prism groove 8, and is in close contact with the wiring harness of the plug to be inspected, thereby forming a sealed environment between the storage seat 3 and the pressure plate 11. At this time, the inflation device 2 is started and inflates the storage groove 12, and then provides detection of the piston plate 14 through the distance sensor 30. When the position of the piston plate 14 is offset, an electrical signal will be transmitted to the display screen 15, thereby improving the convenience of observation.

[0033] The prism rubber column 16 is made of rubber, and will produce excessive deformation during the actual extrusion process, resulting in an increase in the gap, which affects the sealing between the wiring harness and the prism rubber column 16.

[0034] A protrusion 18 is fixedly connected to one of the pyramidal rubber columns 16 , and the protrusion 18 is plugged into the other pyramidal rubber column 16 . The provision of the protrusion 18 facilitates the connection of the two pyramidal rubber columns 16 .

[0035] An arcuate groove 29 is provided on one side of the constraint hole 17 of the pyramidal rubber column 16, and the arcuate grooves 29 of the two pyramidal rubber columns 16 correspond to each other. By providing the arcuate groove 29, the pyramidal rubber column 16 can be easily squeezed, and the force squeezed can be improved to achieve a better sealing effect.

[0036] The outer side of the pyramid rubber column 16 contacts an extrusion ball 28 , which is rotatably embedded in the storage seat 3 and located in the pyramid groove 8 . The arrangement of the extrusion ball 28 reduces friction.

[0037] When the connecting tube 5 is connected to the card slot 6, it will be worn by the mechanical equipment, which will cause a gap and affect the accuracy of the detection.

[0038] The storage seat 3 is located in the storage slot 12 and is fixedly connected to an electric push rod 23. One end of the electric push rod 23 corresponds to the piston plate 14. The electric push rod 23 drives the piston plate 14 to move to the contact block bar 31, which can form a detection basis and facilitate intuitive monitoring of the distance sensor 30.

[0039] The arc-shaped block 24 is fixedly connected in the card slot 6, the arc-shaped block 24 is fixedly connected with the clamping ring 26, the clamping ring 26 is located on both sides of the arc-shaped block 24, by setting the arc-shaped block 24, the limiting and extruding of the rubber pad ring 25 can be increased, thereby providing the connection of the connecting pipe 5 and the storage seat 3.

[0040] The arc-shaped block 24 is contacted with the rubber pad ring 25, the rubber pad ring 25 is sleeved outside the connecting pipe 5, by setting the rubber pad ring 25, the sealing property of the connecting pipe 5 and the storage seat 3 and the pressing plate 11 is increased.

[0041] Please refer to Figures 1-4 Further improvement is made on the basis of example 1.

[0042] Please refer to Figures 1-4 Further improvement is made on the basis of example 1.
