Description

Technical Field

[0001] The utility model relates to a cable conduction insulation tester, belonging to the field of cable testing. Background Art

[0002] One-to-one adapter cables for aviation are widely used in the aviation field to achieve electrical connection between airborne fire control equipment and test equipment. The traditional method for testing the conduction and insulation of one-to-one adapter cables for aviation is to use a multimeter to measure. The red test lead of the multimeter touches one pin and the black test lead touches another pin. The resistance value measured is used to determine whether the two pins are conductive or insulated. This method determines the conduction state of the cable network by converting the test resistance measured by the multimeter. The test is cumbersome and inefficient.

[0003] Therefore, the portable cable comprehensive tester with patent number ZL201821615928.0 proposes a cable tester, which realizes automatic insulation test of multi-core cables through continuity test, and then realizes automatic insulation test of multi-core cables through insulation test module and relay array, and proposes a portable design concept.

[0004] However, in the aviation field, cables are installed at different heights. During subsequent maintenance and inspection, testing cables located at high altitudes requires personnel to support the entire tester with their hands. Over time, the support stability will be greatly reduced, and the efficiency of subsequent cable testing will also be affected. Therefore, the present application proposes a cable conductivity insulation tester that can be adsorbed and fixed. Utility Model Content

When not in use, the lock 12 locks and fixes the flip cover 11 and the protective shell 1. The lock 12 can be any common locking tool on the market.

[0029] See also Figure 1-3 The detection instrument body includes a touch screen 13, an insulation test interface 14, a continuity test interface 15 and a terminal 16 for controlling the conductive performance of the cable line, which are arranged on the workbench 2. The insulation test interface 14 is an insulation test aviation socket, and the continuity test interface 15 is a continuity test aviation plug. An insulation gear adjustment knob 17 is arranged on the workbench 2, and the insulation gear adjustment knob 17 is arranged with three gears. A plurality of control buttons 18 for controlling the touch screen 13 are arranged on the workbench 2. The workbench 2 has a setting space 19 inside, and the setting space 19 is arranged inside A control host, the control host includes a test circuit board 20, a controller, a memory and a charging power supply 21, the test circuit board 20, the controller, the memory and the charging power supply 21 are all installed on a heat conducting plate 22, the interior of the heat conducting plate 22 is cavity-shaped, and a heat conducting pipe 23 is fixedly penetrated on the heat conducting plate 22, both ends of the heat conducting pipe 23 pass through the outside of the protective shell 1, both ends of the heat conducting pipe 23 are openings, and dustproof nets are pasted on the inner sides of both ends of the heat conducting pipe 23, and a charging port 24 and a power switch corresponding to the charging power supply 21 are provided on the protective shell 1.

[0030] The tester of the present application is divided into two parts: a host and a terminal. During the conduction test, the host superimposes voltage on each core of the cable one by one according to the line type definition of the cable. The other end of the cable is connected to the terminal. The terminal works through the voltage and sends the corresponding code to the core. The host side parses the received terminal code of the core and compares it with the host side code to determine whether it meets the line type definition.

[0031] During the insulation test, the tested cable is automatically divided into the tested core and the remaining cores, and the remaining cores are automatically connected in parallel. The tested core is superimposed with the insulation test high voltage, the insulation value of the tested core and the remaining cores is tested, and the insulation value and the line type setting standard value are judged to determine whether the test result is qualified. By connecting the host and the terminal at both ends of the cable respectively, and the host side provides voltage, the terminal sends codes, the host side decodes, and the cable line type is customized, etc., a flexible test of the conduction of multi-core cables is realized. Through the insulation test module and the relay array, the insulation test of multi-core cables is realized automatically.

[0032] During the long-term detection process, the test circuit board 20 and other components designed on the heat conductive plate 22 have a certain heat generation, so the heat generated is transferred on the heat conductive plate 22 and inside the heat conductive plate 22. The internal heat can be transferred to the heat conductive pipe 23. The heat conductive pipe 23 is a hollow heat conductive pipe, and its heat conductive material is aluminum and copper. The hollow heat conductive pipe facilitates heat transfer to the outside. The hollow heat conductive pipe and the internal hollow heat conductive plate 22 greatly reduce the weight of its design.

[0033] See also Figure 1-3 Both ends of the heat pipe 23 are open, and dustproof nets are pasted on the inner sides of both ends of the heat pipe 23. The protective shell 1 is provided with a charging port 24 and a power switch corresponding to the charging power supply 21. The design of the dustproof net prevents external dust from entering the heat pipe 23 and accumulating, thereby improving its heat dissipation effect.

[0034] See also Figure 1 and Figure 4 The protective shell 1 and the pipe 3 are connected by a retractable telescopic rod, and the telescopic rod includes a sleeve 25 and an insertion rod 26 inserted into the sleeve 25. A locking screw 27 is threadedly inserted on the sleeve 25, and the insertion rod 26 is inserted into the sleeve 25. The insertion rod 26 can be manually extended and moved, so the length of the telescopic rod can be increased. Finally, the locking screw 27 is rotated so that the other end of the locking screw 27 is pressed against the insertion rod 26 to complete the fixation. Therefore, the position of the suction cup 4 can be changed, and it can correspond to some uneven adsorption surfaces, such as some stair-shaped adsorption surfaces, so that the suction cup 4 can be better attached to the adsorption surface, and the auxiliary pipeline is designed as a hose.

[0035] During specific work, the present application utilizes the detection instrument body on the workbench 2 to perform a continuity and insulation test on aviation cables.

[0036] During the test process, in order to avoid the personnel from supporting the entire tester with their hands all the time, the suction cup 4 is designed to be adsorbed on the place that needs to be tested, such as the wall of aviation equipment, and the adsorption can fix the tester in the air at a certain height. Because some cables are installed at high places in aviation equipment, during the test process, it is avoided that the personnel manually support the entire instrument, thereby greatly increasing the efficiency of the test.

[0037] The control circuit board 7 controls the vacuum pumping motor 9 to start, and the vacuum pumping motor 9 extracts the air in the suction cup 4, so that the suction cup 4 is adsorbed on the surface of the object. The air pressure monitoring module monitors the air pressure in the suction cup 4. When the air pressure in the suction cup 4 is higher than the set value, the control circuit board 7 controls the vacuum pumping motor 9 to pump air to the set value and then stop pumping, so that the suction cup 4 always maintains the vacuum adsorption state. The subsequent release of air by the release valve 10 facilitates the entry of air into the suction cup 4 and is easy to remove.

[0038] The memory has a storage unit to effectively save the test results. The test circuit board includes a conduction array for testing the conductivity of the cable line, a coding analysis array and a protection circuit for controlling the conductivity test of the cable line, and a relay sequence for testing the insulation performance of the cable.

[0039] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
