A support plate 103 is fixedly connected to both sides of the bottom of the inner wall of the testing box 101. A contact impedance tester 104 is provided on the front side of the top of the inner wall of the testing box 101. An installation box 105 is provided on both sides of the bottom of the testing box 101. A cooling fan 106 is fixedly installed inside the installation box 105. The lifting and bonding mechanism 200 includes a lifting hydraulic cylinder 201, which is fixedly connected to the top of the detection box 101. The output end of the lifting hydraulic cylinder 201 passes through the bottom of the detection box 101. The output end of the lifting hydraulic cylinder 201 is fixedly connected to a lifting plate 202. The bottom of the front side of the lifting plate 202 is fixedly connected to a mounting tube 203. The contact impedance tester 104 is arranged inside the mounting tube 203. The front side of the inner wall of the mounting tube 203 is fixedly connected to a bonding component 204.

[0029] The downward positioning assembly 102 includes an electric telescopic rod 102a, and an elastic pressing member 102b is fixedly connected to the output end of the electric telescopic rod 102a.

[0030] The fitting component 204 includes a spring 204a, the rear end of the spring 204a is fixedly connected to a magnetic suction cup 204b, the contact impedance tester 104 is fixedly installed on the rear side of the magnetic suction cup 204b, the front side of the inner wall of the mounting tube 203 is fixedly connected to an electromagnet 204c, the electromagnet 204c is magnetically connected to the magnetic suction cup 204b, the top of the movable frame 301 is fixedly connected to a push-type switch 204e, and the push-type switch 204e is movably connected to the lifting plate 202.

[0031] Specifically, the lifting plate 202 will drive the installation tube 203 to move downward during the downward movement. As the lifting plate 202 moves, the push-type switch 204e on the movable frame 301 will be pressed down. At this time, the installation tube 203 is perpendicular to the cable connector. At this time, the push-type switch 204e is pressed to turn off the electromagnet 204c, so that the electromagnet 204c loses its adsorption to the magnetic suction cup 204b, so that the spring 204a can drive the magnetic suction cup 204b to move backward through its own elastic force, so that the magnetic suction cup 204b can drive the contact impedance tester 104 to fit the surface of the cable connector, so that the contact impedance tester 104 can adapt to cable connectors of different sizes.

[0032] Furthermore, the lifting hydraulic cylinder 201 is started, so that the lifting hydraulic cylinder 201 can drive the lifting plate 202 to move downward, and when the lifting plate 202 moves downward, it will drive the installation tube 203 and the gear plate frame 304b to move downward synchronously.

[0033] As the lifting plate 202 moves downward, it will contact the push switch 204e on the movable frame 301. At this time, the installation tube 203 on the lifting plate 202 will be perpendicular to the cable connector. After the push switch 204e is squeezed by the lifting plate 202, the electromagnet 204c will be closed, so that the spring 204a inside the installation tube 203 can drive the magnetic suction cup 204b to move backward through its own elastic force. After the magnetic suction cup 204b moves backward, it can drive the contact impedance tester 104 to move backward, so that it fits the cleaned cable connector surface, thereby testing the cable connector.

[0034] The electric telescopic rod 102a drives the elastic pressing member 102b to press the cable tightly against the inside of the detection box 101.

[0037] The rotating assembly 304 includes a residual tooth ring 304a, and tooth plate frames 304b are movably connected on both sides of the bottom of the lifting plate 202. The top and bottom of both sides of the moving frame 301 are fixedly connected to fixed shaft frames 304c. The surface of the fixed shaft frame 304c is movably connected to a gear 304d, and the gear 304d is engaged with the tooth plate frame 304b. The gear 304d is engaged with the residual tooth ring 304a. The interior of the tooth plate frame 304b is movably connected to a connecting plate 304e, and the inner side of the connecting plate 304e is fixedly connected to the outer side of the moving frame 301. Connecting parts 304f are provided on both sides of the bottom of the lifting plate 202.

[0038] The connecting component 304f includes a connecting groove 304f1, and a connecting block 304f2 is movably connected inside the connecting groove 304f1. The bottom of the connecting block 304f2 is fixedly connected to the top of the tooth plate frame 304b.

[0039] The tensioning assembly 307 includes a mounting block 307a, and mounting grooves 307b are provided at the top and bottom of the inner wall of the rotating cylinder 302. A tension spring 307c is fixedly connected to the outer side of the inner wall of the mounting groove 307b, and the inner end of the tension spring 307c is fixedly connected to the inner side of the mounting block 307a.

[0040] The sliding assembly 308 includes a sliding ring 308a. Sliding grooves 308b are formed on both sides of the inner wall of the movable frame 301. The sliding ring 308a is movably connected to the sliding grooves 308b.

[0041] The separation assembly 309 includes a fixed axis plate 309a, the surface of the fixed axis plate 309a is movably connected to a connecting axis plate 309b, the rear side of the top of the connecting axis plate 309b is movably connected to a connecting axis frame 309c, the top of the connecting axis frame 309c is fixedly connected to the bottom of the movable frame 301, both sides of the bottom of the inner wall of the detection box 101 are fixedly connected to guide grooves 309d, the bottom of the installation box 105 is fixedly connected to a guide plate 309f, and the guide plate 309f is movably connected to the guide groove 309d.

[0042] The inner wall of the movable frame 301 is movably inlaid with balls A, which are distributed in a circular shape with equal distances. The balls A are movably connected to the rotating cylinder 302.

[0043] The top of the fixed shaft plate 309a is fixedly connected to a limit plate B, and the limit plate B is movably connected to the connecting shaft plate 309b.

[0044] Specifically, when the lifting plate 202 moves downward, the toothed plate frame 304b inside the rotating assembly 304 will be driven to move downward, so that after the toothed plate frame 304b moves downward, it can drive the gear 304d on the surface of the fixed shaft frame 304c to rotate, so that after the gear 304d rotates, it can drive the residual tooth ring 304a to rotate, so that after the residual tooth ring 304a rotates, it can drive the rotating cylinder 302 to rotate, so that the rotating cylinder 302 can drive the internal cleaning cloth 305 to clean the surface of the cable connector. At the same time, the use of two gears 304d can ensure that the transmission of the residual gear 304d will not be lost, and the connecting plate 304e can synchronously drive the toothed plate frame 304b to move when the moving frame 301 moves, ensuring the engagement of the toothed plate frame 304b with the gear 304d.

[0045] The connection groove 304f1 and the connection block 304f2 of the connection member 304f cooperate to ensure that the tooth plate frame 304b will not separate from the lifting plate 202 when the lifting plate 202 moves at the bottom.

[0046] The tension spring 307c in the mounting groove 307b inside the tensioning assembly 307 can drive the mounting block 307a to move outward, so that the mounting block 307a can drive the mounting plate 306 to move outward, thereby enabling the mounting plate 306 to stretch and tighten the cleaning cloth 305, so that the cleaning cloth 305 can fit tightly against the surface of the cable connector and can adapt to cable connectors of different sizes.

[0047] The sliding ring 308a and the sliding groove 308b inside the sliding assembly 308 ensure that the rotating cylinder 302 can rotate stably inside the moving frame 301, and at the same time can limit the rotating cylinder 302 to prevent the rotating cylinder 302 from separating from the moving frame 301.

[0048] When the movable frame 301 moves forward, it will drive the connecting axis frame 309c to move forward, so that the connecting axis frame 309c can push the connecting axis plate 309b to move forward, so that the connecting axis plate 309b can push the fixed axis plate 309a to move forward, so that the fixed axis plate 309a can drive the installation box 105 to move forward, so that the installation box 105 will be guided by the guide block and the guide groove 309d and move outward, so that the installation box 105 can drive the cooling fan 106 to move outward, and at the same time, when the movable frame 301 is reset, it will drive the cooling fan 106 to reset, so as to avoid the movable frame 301 touching the cooling fan 106 and damaging it when cleaning the surface of the cable connector.

[0049] The balls A inside the moving frame 301 can reduce the friction between the moving frame 301 and the rotating drum 302 , thereby making the rotating drum 302 rotate more smoothly inside the moving frame 301 .

[0050] The limiting plate B can limit the connecting shaft plate 309b on the surface of the fixed shaft plate 309a, thereby preventing the connecting shaft plate 309b from being separated from the fixed shaft plate 309a.

[0051] Furthermore, before the cable joint needs to be inspected, the horizontal hydraulic cylinder 303 is started so that the horizontal hydraulic cylinder 303 can push the movable frame 301 to move forward, so that the movable frame 301 can drive the rotating cylinder 302 to move forward after moving forward, so that the rotating cylinder 302 can drive the internal cleaning cloth 305 to move forward after moving forward, so that the cleaning cloth 305 can fit the surface of the cable joint, and at the same time, the internal tension spring 307c of the mounting groove 307b can drive the mounting block 307a to move outward through its own tension, so that the mounting block 307a can drive the mounting plate 306 to move outward after moving outward, so that the mounting plate 306 can drive the tightened cleaning cloth 305, so that the cleaning cloth 305 can fit tightly against the surface of the cable joint.

[0052] When the moving frame 301 moves forward, the connecting plate 304e drives the tooth plate frame 304b to move forward synchronously. At this time, the tooth plate frame 304b drives the connecting block 304f2 to move inside the connecting groove 304f1 at the bottom of the lifting plate 202.

[0053] At the same time, when the movable frame 301 moves forward, it will drive the connecting axis frame 309c to move forward, so that after the connecting axis frame 309c moves forward, it can drive the connecting axis plate 309b to move forward, so that the connecting axis plate 309b can drive the installation box 105 to move, so that the installation box 105 can drive the guide block to move inside the guide groove 309d, so that the installation box 105 can drive the cooling fan 106 to move in communication with the movable frame 301.

[0054] Then the lifting hydraulic cylinder 201 is started, so that the lifting hydraulic cylinder 201 can drive the lifting plate 202 to move downward, and when the lifting plate 202 moves downward, it will drive the installation tube 203 and the gear plate frame 304b to move downward synchronously.

[0055] When the tooth plate frame 304b moves downward, it will drive the gear 304d on the surface of the fixed shaft frame 304c to rotate, so that the gear 304d can rotate and mobilize the meshing residual tooth ring 304a to rotate, so that the residual tooth ring 304a can drive the rotating cylinder 302 to rotate, so that the rotating cylinder 302 can rotate inside the movable frame 301 through the sliding ring 308a and the sliding groove 308b, so that the rotating cylinder 302 can drive the cleaning cloth 305 that is in contact with the cable connector to rotate through the mounting block 307a and the mounting plate 306 inside the mounting groove 307b, so that the rotating cleaning cloth 305 rotates to clean the surface of the cable connector.

[0056] It should be noted that after the lifting plate 202 is attached to the moving frame 301 , the rotating cylinder 302 rotates one circle, and the opening is still facing the contact impedance tester 104 .

[0057] The remaining structures are the same as those of Example 1.

[0058] Example 3 Reference Figures 1 to 5 , which is the third embodiment of the present invention, is different from the second embodiment in that: a cable connector connection fault detection device.

[0059] First, the electric telescopic rod 102a drives the elastic pressing member 102b to press the cable tightly and install it inside the detection box 101.

[0060] Before the cable joint needs to be inspected, the horizontal hydraulic cylinder 303 is started so that the horizontal hydraulic cylinder 303 can push the movable frame 301 to move forward, and after the movable frame 301 moves forward, it can drive the rotating cylinder 302 to move forward, and after the rotating cylinder 302 moves forward, it can drive the internal cleaning cloth 305 to move forward, so that the cleaning cloth 305 can fit the surface of the cable joint. At the same time, the tension spring 307c inside the mounting groove 307b can drive the mounting block 307a to move outward through its own tension, so that after the mounting block 307a moves outward, it can drive the mounting plate 306 to move outward, so that the mounting plate 306 can drive the tightened cleaning cloth 305, so that the cleaning cloth 305 is in close contact with the surface of the cable joint.

[0061] When the moving frame 301 moves forward, the connecting plate 304e drives the tooth plate frame 304b to move forward synchronously. At this time, the tooth plate frame 304b drives the connecting block 304f2 to move inside the connecting groove 304f1 at the bottom of the lifting plate 202.

[0062] At the same time, when the movable frame 301 moves forward, it will drive the connecting axis frame 309c to move forward, so that after the connecting axis frame 309c moves forward, it can drive the connecting axis plate 309b to move forward, so that the connecting axis plate 309b can drive the installation box 105 to move, so that the installation box 105 can drive the guide block to move inside the guide groove 309d, so that the installation box 105 can drive the cooling fan 106 to move in communication with the movable frame 301.

[0063] Then the lifting hydraulic cylinder 201 is started, so that the lifting hydraulic cylinder 201 can drive the lifting plate 202 to move downward, and when the lifting plate 202 moves downward, it will drive the installation tube 203 and the gear plate frame 304b to move downward synchronously.

[0064] When the tooth plate frame 304b moves downward, it will drive the gear 304d on the surface of the fixed shaft frame 304c to rotate, so that the gear 304d can rotate and mobilize the meshing residual tooth ring 304a to rotate, so that the residual tooth ring 304a can drive the rotating cylinder 302 to rotate, so that the rotating cylinder 302 can rotate inside the movable frame 301 through the sliding ring 308a and the sliding groove 308b, so that the rotating cylinder 302 can drive the cleaning cloth 305 that is in contact with the cable connector to rotate through the mounting block 307a and the mounting plate 306 inside the mounting groove 307b, so that the rotating cleaning cloth 305 rotates to clean the surface of the cable connector.

[0065] As the lifting plate 202 moves downward, it will contact the push switch 204e on the movable frame 301. At this time, the installation tube 203 on the lifting plate 202 will be perpendicular to the cable connector. After the push switch 204e is squeezed by the lifting plate 202, the electromagnet 204c will be closed, so that the spring 204a inside the installation tube 203 can drive the magnetic suction cup 204b to move backward through its own elastic force. After the magnetic suction cup 204b moves backward, it can drive the contact impedance tester 104 to move backward, so that it fits the cleaned cable connector surface, thereby testing the cable connector.

[0066] After the detection is completed, the lifting hydraulic cylinder 201 and the horizontal hydraulic cylinder 303 can be started to drive each component to reset, thereby facilitating the next detection of the cable joint.

[0067] In summary, the lifting and fitting mechanism 200 can drive the contact impedance tester 104 to move to the front side of the cable, and at the same time, when the contact impedance tester 104 is in front of the cable connector, it can fit with the cable connector, so that the contact impedance tester 104 can adapt to cable connectors of different sizes. At the same time, the cleaning cloth 305 inside the rotating cleaning mechanism 300 cooperates with the rotating assembly 304 to clean the surface of the cable connector when the lifting plate 202 drives the contact impedance tester 104 to move downward, thereby completing the cleaning of the cable connector before the contact impedance tester 104 detects it and performing the detection after cleaning.
