Description

Technical Field

[0001] The utility model belongs to the technical field of cable testing, in particular to an electrical performance switching device that automatically finds a line. Background Art

[0002] Cables are indispensable components in many industries such as aerospace, rail transportation, and electric power. They mainly provide power and transmit control signals, and are generally connected between two power components. To ensure the correctness of power supply and signal transmission, the cable must be tested for its conductivity and insulation performance before use. Only cables that meet process requirements can ensure the normal operation of the system. In some practical applications, it is necessary to pre-bury some cables in the equipment, such as the attached Figure 1 As shown, after the cable is laid, both ends are loose wires. Because the middle portion is laid inside the equipment, the one-to-one relationship between the two cables cannot be identified. Therefore, when performing continuity and insulation resistance tests, a scan must be performed to confirm the connection relationship before initiating the scan. Furthermore, because the cable ends are loose wires, they cannot be directly connected to the test instrument. Therefore, a transition tool is required to effectively connect the cable under test to the test instrument. During the test process, if a false connection or fault occurs, the tester must search for the fault point among numerous cables and troubleshoot it one by one, which is time-consuming and labor-intensive.

[0003] When testing unmarked cables with the insulation stripped at both ends, you first need to connect both ends of the cable to the test instrument. Typically, test instruments offer standard interfaces, such as Omron connectors and multi-core cold-press connectors. However, due to the loose wires, it's difficult to quickly connect the cable to the test instrument, and when a fault occurs, it's difficult to quickly locate the fault. Therefore, to improve testing efficiency, a tooling set is required that can quickly connect the cable to the test instrument and assist in fault location.

[0004] Currently, the primary method involves using a multimeter's beeping mode to randomly scan both ends of the cable under test and identify the wiring sequence. Once this sequence is determined, a multimeter and megger are used to test the on-resistance and insulation resistance. Other, more automated methods utilize automated test equipment. After the cable under test is connected to the tester via connectors, the instrument automatically scans the wiring sequence and performs electrical performance testing. However, these methods still fail to address the issues of confusing wiring and difficulty locating the fault point.

[0005] In summary, the shortcomings of the existing technology are mainly reflected in two points: on the one hand, when the cables to be tested are connected to the test instrument, they are tangled and very chaotic, and the connection between the end terminal and the wire is prone to breakage due to long-term bending; on the other hand, when a fault occurs, since the cables are entangled with each other, it is necessary to check the cables one by one when finding the faulty cable, which is time-consuming and labor-intensive. Summary of the Invention

[0006] The utility model provides an electrical performance adapter with automatic line finding. On the one hand, by rationally planning and designing the end connection structure, the connection efficiency is quickly improved and the bending frequency at the connection is reduced, thereby reducing the probability of damage; on the other hand, by introducing the automatic line finding function, it can assist testers in quickly completing the access of the cable to be tested and the fault point search work, thereby improving efficiency.

[0061] The following combination Figures 1-11 The electrical performance switching device for automatic line finding provided by the present invention is introduced in detail, and the embodiment in which the total number of cable cores is 192 is used as an example for explanation.

[0062] Combine Figure 2 As shown, in an embodiment of the present invention, the test system includes a transfer fixture A, a transfer fixture B, a test instrument, and a test host. Transfer fixtures A and B have identical structural designs and functions. When testing a faulty cable, the two ends of the cable under test are connected to transfer fixtures A and B, respectively, and then to the test instrument, forming a closed-loop circuit for troubleshooting cable faults.

[0067] Furthermore, the adapter box 3 is used to connect the remote cable 2 and the proximal cable 5, provides a portable plug-in interface, improves the maintainability of the adapter tooling, and provides a hanging position for the portable RFID all-in-one machine 4.

[0068] Furthermore, the portable RFID integrated machine 4 is used to identify the luminous tag 150 according to the fault sequence number to find the fault line.

[0069] Combine Figure 4-Figure 6 As shown, the junction box 1 includes a first base plate 11, a second base plate 12, a first upper cover 13, a second upper cover 14 and a plurality of connection terminals 15. Generally, each junction box 1 includes 2 base plates, 2 upper covers, 10 connection terminals and 10 luminous labels.

[0070] Furthermore, the first bottom plate 11 and the second bottom plate 12 have the same structure, and the first upper cover 13 and the second upper cover 14 have the same structure.

[0071] Furthermore, the junction box 1 consists of an upper and lower structure, the first base plate 11 and the first upper cover 13 constitute the upper structure, the second base plate 12 and the second upper cover 14 constitute the lower structure, each layer has 5 connection terminals and 5 luminous labels, and each layer can be connected to at least 5 core wires.

[0072] Combine Figure 7 As shown, the first bottom plate 11 is provided with a plurality of first connection terminal fixing grooves 110 for placing and limiting the connection terminals 15 .

[0073] Furthermore, the second bottom plate 12 is provided with a plurality of second connection terminal fixing grooves 120 for placing and limiting the connection terminals 15 .

[0074] Furthermore, a plurality of third connection terminal fixing grooves 130 are provided on one side of the upper end surface of the first upper cover 13 , and a first wire pressing groove 131 is provided on the opposite side.

[0075] Furthermore, a plurality of fourth connection terminal fixing grooves 140 are provided on one side of the upper end surface of the second upper cover 14 , and a second wire pressing groove 141 is provided on the opposite side.

[0076] Furthermore, the first connecting terminal fixing groove 110 of the first base plate 11 and the third connecting terminal fixing groove 130 of the first upper cover 13, and the second connecting terminal fixing groove 120 of the second base plate 12 and the fourth connecting terminal fixing groove 140 of the second upper cover 14 correspond one to one to jointly complete the fixation of the connecting terminal 15, and each third connecting terminal fixing groove 130 and the fourth connecting terminal fixing groove 140 is provided with a fixing buckle for positioning the connecting terminal 15.

[0077] Furthermore, the first bottom plate 11 and the first wire pressing groove 131 of the first upper cover 13 jointly complete the fixing and compaction of the wires, and the second bottom plate 12 and the second wire pressing groove 141 of the second upper cover 14 jointly complete the fixing and compaction of the wires.

[0078] Furthermore, when the 10-core wire bundle is connected to the junction box 1, it is divided into 2 groups, with 5 cores in each group, and is pressed into the corresponding terminal 15 through the first wire pressing groove 131 and the second wire pressing groove 141. After being pressed into place, this part of the structure is tightly pressed with the corresponding base plate.

[0079] Combine Figure 8 As shown, each connection terminal 15 is provided with a light-emitting label 150 and an indicator light 151 .

[0080] Combine Figure 9 As shown, the remote cable 2 has a total core count of N and is divided into M bundles at the end, each bundle containing 10 cores. M is the value of N modulo 10, with 1 added if the value is not an integer. Each bundle contains 10 cores, a design value determined based on extensive field experiments. When each bundle has 10 cores, the problem of wire entanglement is virtually eliminated.

[0081] Furthermore, the remote cable 2 is divided into M bundles at the terminal. The first (M-1) bundles each contain 10 cores, and the last bundle contains N-(M-1)*10 cores. M is the modulo 10 of N, and 1 is added if the number is not an integer. The number of conductors connected to the junction box 1 in the last bundle is less than or equal to 10. For example, if the total number of cores is 192, the remote cable 2 is divided into 20 bundles, of which the first 19 bundles each contain 10 cores, and the last bundle contains 2 cores.

[0082] Combine Figure 10 As shown, the adapter box 3 includes a box body 31 and male aviation plug panels 32 symmetrically arranged on both side end surfaces of the box body 31 , and the male aviation plug panel is provided with a plurality of male aviation plugs 320 .

The female aviation plugs can be plugged into any of the male aviation plug panels 32. The remote cable 2 and the adapter box 3 are connected via the female aviation plugs and the male aviation plug 320.

[0084] Furthermore, the proximal cable 5 and the adapter box 3 are connected in the same manner as the distal cable 2 and the adapter box 3 .

[0085] Furthermore, this embodiment uses a total of 192 cores as an example. Six male aviation plugs 320 are evenly arranged on the male aviation plug panel 32, each with 32 cores. The female aviation plugs match the male aviation plugs 320, each containing 32 pins.

[0086] Furthermore, the portable RFID integrated device 4 is used to check for faulty cables. When the portable RFID integrated device 4 is brought close to the cable to be tested, the target RFID tag changes color. When the RFID integrated device 4 is brought close to the terminal 15, the indicator light 150 changes to green.

[0087] Furthermore, one end of the proximal cable 5 is connected to the adapter box 3, and the other end is welded to the standard connector of the test instrument. The number of cores of each cable can be set arbitrarily according to actual conditions, and the common core numbers mainly include 16 cores and 32 cores.

[0088] Combine Figure 11 The figure shows a complete adapter set, using a cable with 192 cores as an example. Designs for other core numbers can follow this design principle. At the far end of the adapter is a connector 15, used to connect the loose wires of the cable under test. Connector 15 is fixed to junction box 1. Junction box 1 primarily consists of two base plates, two upper covers, 10 terminal blocks, and 10 luminous labels. The base plates and upper covers are secured with bolts. At the far end of cable 2, adapter fixture A is divided into 20 bundles. The first 19 bundles contain 10 cores each, and the last bundle contains 2 cores. At the transition section, at adapter box 3, the cables are divided into six bundles, each containing 32 cores. Adapter box 3 features male connector panels 32 on both sides. Six bundles of 32-core cables are connected to each side, ultimately consolidating the six bundles into a single cable. Among them, the male aviation plug panels 32 on both sides of the adapter box 3 are male aviation plugs 320, which correspond one-to-one to the female aviation plugs of the male aviation plug 320. The RFID all-in-one machine 4 is used to receive the test host message and complete the automatic search of the RFID luminous tag.

[0089] This utility model provides a switching fixture suitable for testing the electrical properties of cables with loose wires at both ends. This switching fixture allows for quick connection of various loose-wire cables, while its unitized design at the ends prevents cable entanglement during wiring. The RFID-based luminous tag design helps users quickly locate cable faults, reducing manual troubleshooting time. Furthermore, the modular design of the switching box enhances the switch's maintainability.
