Description

Technical Field

[0001] The utility model relates to the field of wire material testing, and more specifically, to a testing device for a drag chain cable. Background Art

[0002] Dust-free drag chains are mainly used in scenarios with high cleaning environment standards, such as semiconductor manufacturing, precision machining, pharmaceutical manufacturing, food processing and other industries. They can effectively prevent the accumulation of dust and particles, and protect the cleanliness and safety of cables or pipelines. They usually have good sealing performance and can operate stably in high-standard clean room environments, reducing system maintenance costs and system downtime.

[0003] The dust-free drag chain is composed of multiple cables. As an important electrical equipment in the drag chain system, each cable needs to be tested before being assembled into a drag chain, and a comprehensive wire tester will be used in the testing process. The wire tester is an instrument used to test connectors of multiple strands of wires or multiple connectors. Usually, these wires or connectors need to be tested for continuity, short circuit, short circuit, instantaneous on / off, crossover and other on-off conditions. It is also necessary to test the withstand voltage, insulation and other safety parameters between wires and between wires and shielding layers. Some wiring harnesses will have components such as capacitors, inductors, resistors or diodes, which also need to be tested or lit.

[0004] When conducting wire testing, a wire comprehensive tester and a PCB board are often used for device combination testing. However, since the test wire has many pins on the PCB board, each pin needs to be connected to multiple test wires through a horn plug. However, the wiring harness of the PCB board needs to be frequently replaced at the output end for each different performance test. Such an operation will take a lot of time to replace and connect the output wiring harness when a large number of cable tests are required. At the same time, since there will be wire tests of different interfaces during the test process, and the large number of test output wires will also cause multiple wires to be entangled with each other during the replacement of the output wires, reducing the efficiency of the test.

[0005] At present, there is no corresponding improvement on the wire testing device for dust-free drag chains. At the same time, a power system fault detection device is disclosed. Through the set fixed plate and the winding assembly thereon, the wire can be directly wound on the corresponding winding drum during operation, and the two ends of the wire can be clamped and fixed through the clamping assembly to ensure that in the subsequent work process, multiple wires are avoided as much as possible from being entangled together during operation.

[0006] However, although the above device can avoid the problem of multi-wire entanglement, the use of the winding component is not applicable to the test of various types of ports of the wires in the drag chain, and it cannot solve the need for multiple connection replacements during this process; moreover, there will be relatively thin wire harnesses during the detection process, and the winding method may even cause wire breakage, signal transmission or poor contact during the test process. Summary of the Invention

[0007] The present utility model provides a test device for a drag chain cable to overcome the defects of the prior art such as long time for replacing and connecting the output wire harness, easy mutual entanglement of wires, and reduced test efficiency.

[0008] To solve the above technical problems, the technical solution of the present utility model is as follows:

[0009] A test device for a drag chain cable includes a wire tester and a PCB board fixing seat; the wire tester is provided with a first output end and a first input end for connecting a wire harness.

[0010] The PCB board fixing seat includes at least two PCB boards for detecting wires. The PCB boards are divided into a fixed-end PCB board and a mobile-end PCB board. Both the fixed-end board and the mobile-end PCB board are provided with a second input end and a second output end.

[0011] The first output end is connected to the second input end of the fixed-end PCB board through a wire harness; the first input end is connected to the second input end of the mobile-end PCB board through a wire harness.

[0012] The test device for the drag chain cable further includes a fixing plate for fixing the test wire. A number of fixed-end test wires and mobile-end test wires are provided on the fixing plate.

[0013] One end of the fixed-end test wire is connected to the wire harness of the second output end on the fixed-end PCB board.

[0014] One end of the mobile-end test wire is connected to the wire harness of the second output end on the mobile-end PCB board.

[0015] The other end of the fixed-end test wire is connected to the cable to be tested; the other end of the cable to be tested is connected to the mobile-end test wire.

[0016] The first output end and the second input end refer to the flow direction of current or signal in the device. For example, the first output end of the wire tester can also be used as the first input end as long as a complete circuit is formed; the solder joint directly connected to the wire tester on the PCB board is defined as the second input end, and the solder joint connected to the horn plug or directly welding the wire harness on the PCB board is defined as the second output end.

[0017] The fixed end and the mobile end are defined with respect to the test object. The PCB board through which the current or signal at the output end of the wire tester first passes is defined as the fixed end, and the PCB board through which the current or signal passes after passing through the cable to be tested and then flows through is defined as the mobile end.

[0018] Further, one end of the wire harness at the second output end is connected to the wire transfer interface, and is connected to one end of the test wire for the fixed end or the test wire for the mobile end through the wire transfer interface.

[0019] Further, a silica gel sheath for bundling multiple wire harnesses is provided at the end of the wire harness at the first output end.

[0020] By adopting the above technical solution, the silica gel sheath can tightly bundle multiple wire harnesses together, avoiding the situation where the wire harnesses are entangled with each other during the test. By keeping the wire harnesses neatly and orderly arranged, the operator can connect and replace them more conveniently, improving work efficiency and reducing the time waste caused by wire harness entanglement.

[0021] Further, the first output end, the first input end and the second output end are all provided with cow horn plugs.

[0022] By adopting the above technical solution, the installation and disassembly process of the wire harness can be significantly simplified by using the cow horn plug, which can reduce the operation time and difficulty, improve the overall work efficiency, and facilitate the maintenance and replacement of the cable. At the same time, the cow horn plug design has good anti-vibration performance, can maintain a stable connection in a vibrating environment, avoid signal interruption or poor contact problems, and avoid signal transmission problems caused by vibration, ensuring the accuracy and continuity of test data.

[0023] Further, the cow horn plug is provided with a plurality of pins, and the pins are connected to the solder joints at the input end or the output end.

[0024] Further, the cow horn plug is also provided with a pin socket for facilitating the connection of the wire harness, and each pin hole on the pin socket corresponds to a pin one by one.

[0025] Further, a wire harness fixing clip for fixing the wire harness is provided at the wire harness interface of the first output end and the first input end.

[0026] By adopting the above technical solution, the stability of the connection between the wire harness and the pins at the output end can be enhanced. The wire harness fixing clip can be installed on the cow horn plug, which can further strengthen the connection stability between the wire harness and the connector. The cow horn plug itself is used to connect multiple pins, and the fixing clip can ensure that these connections remain stable when subjected to external force or vibration, thus avoiding signal transmission problems caused by poor contact.

[0027] Furthermore, the interior of the PCB board fixing seat is hollowed out, and through holes are provided on both sides and the back for facilitating the connection of the wire harness to the second input end.

[0028] By adopting the above technical solution, the heat dissipation performance can be improved. The hollow design inside the PCB board fixing seat can effectively enhance air circulation, improve the heat dissipation performance, and prevent damage to electronic components caused by overheating. During the wire testing process of the PCB board, voltage and current tests of different magnitudes are required. Good heat dissipation performance helps the system maintain stability during long-term high-load operation and extends the service life of the equipment.

[0029] Meanwhile, the hollow design and the through hole arrangement simplify the installation and replacement process of the wire harness. Operators can conveniently introduce and fix the cables without complex tools and steps, reducing the time and difficulty of installation and maintenance and improving work efficiency.

[0030] Furthermore, two fixing plates are provided. One is used to fix the test wire for the fixed end, and the other is used to fix the test wire for the mobile end.

[0031] By adopting the above technical solution, separating the fixation of the test wires for the fixed end and the mobile end allows for more flexible configuration and adjustment of the length and layout of each group of cables to adapt to changes in different test requirements. This design improves the flexibility and adaptability of the system and can meet a wider range of application scenarios.

[0032] Meanwhile, when maintenance or cable replacement is needed, if the cables are mixed together, it is difficult for operators to quickly locate the cables that need to be processed, increasing the time and difficulty of maintenance. Fixing the test wires for the fixed end and the mobile end on different fixing plates respectively enables operators to more conveniently identify and manage each group of cables, quickly perform maintenance or replacement; this design makes the maintenance and replacement of cables faster and more convenient, reducing the workload of operators, improving work efficiency, and reducing the maintenance difficulty.

[0033] Furthermore, unified interfaces for connecting to the wire transfer interface are provided at one end of both the test wire for the fixed end and the test wire for the mobile end; several wiring ports for matching different wire interfaces are provided at the other end of the test wire.

[0034] By adopting the above technical solution, by setting a unified interface at one end of the test wires for the fixed end and the mobile end, the connection operation is simplified and standardized, and the other end is matched with different wire interfaces according to needs. During the test process, different types of wire interfaces will lead to complex connection operations, increasing the operation difficulty and time cost. The unified interface design simplifies the operation steps, making the connection operation faster and more efficient, reducing the complexity caused by the variety of interface types, and improving the overall work efficiency. By adopting the unified interface design, the system can be compatible with and adapt to different wire interfaces, meet diverse test requirements, and improve the flexibility and application range of the system.

[0035] Compared with the prior art, the beneficial effects of the technical solution of the present utility model are as follows:

[0036] The present utility model provides a test device for a drag chain cable, including a wire tester and a PCB board fixing seat; the wire tester is provided with a first output end and a first input end for connecting a wire harness; the PCB board fixing seat includes two PCB boards for detecting wires, and the PCB boards are divided into a fixed-end PCB board and a mobile-end PCB board. Both the fixed-end board and the mobile-end PCB board are provided with a second input end and a second output end; the first output end is connected to the second input end of the fixed-end PCB board through a wire harness; the first input end is connected to the second input end of the mobile-end PCB board through a wire harness; the test device for the drag chain cable further includes a fixing plate for fixing the test wires, and a plurality of fixed-end test wires and mobile-end test wires are arranged on the fixing plate; one end of the fixed-end test wire is connected to the wire harness of the second output end on the fixed-end PCB board; one end of the mobile-end test wire is connected to the wire harness of the second output end on the mobile-end PCB board; the other end of the fixed-end test wire is connected to the cable to be tested; the other end of the cable to be tested is connected to the mobile-end test wire.

[0037] Using the test device for the drag chain cable of the present utility model can reduce the time for replacing and connecting the output wire harness during the wire testing process, avoid the wires being easily entangled with each other, improve the test efficiency, and at the same time can perform wire testing of multiple interfaces, improving the versatility of the device and the convenience of testing.

[0046] Embodiment 1

[0047] As Figure 1-2 described, this embodiment discloses a testing device for a drag chain cable, including a wire tester 1 and a PCB board fixing seat 2; the wire tester 1 is provided with a first output terminal 101 and a first input terminal 102 for connecting a wire harness;

[0048] The PCB board fixing seat 2 includes two PCB boards 201 for detecting wires. The PCB board 201 is divided into a fixed-end PCB board 2011 and a mobile-end PCB board 2012. Both the fixed-end board 2011 and the mobile-end PCB board 2012 are provided with a second input terminal 2013 and a second output terminal 2014;

[0049] The first output terminal 101 is connected to the second input terminal 2013 of the fixed-end PCB board 2011 through a wire harness; the first input terminal 102 is connected to the second input terminal 2013 of the mobile-end PCB board 2012 through a wire harness;

[0050] The test device for the drag chain cable further includes a fixing plate 3 for fixing the test wire, and a plurality of fixed-end test wires 31 and mobile-end test wires 32 are arranged on the fixing plate 3;

[0051] One end of the fixed-end test wire 31 is connected to the wire harness of the second output terminal 2014 on the fixed-end PCB board 2011;

[0052] One end of the mobile-end test wire 32 is connected to the wire harness of the second output terminal 2014 on the mobile-end PCB board 2012;

[0053] The other end of the fixed-end test wire 31 is connected to the cable to be tested; the other end of the cable to be tested is connected to the mobile-end test wire 32.

[0054] One end of the wire harness of the second output terminal 2014 is connected to the wire transfer interface, and is connected to one end of the fixed-end test wire 31 or the mobile-end test wire 32 through the wire transfer interface.

[0055] The wire transfer interface makes the system design more modular, facilitating the connection and replacement between different modules. Operators can quickly replace or upgrade some components without re-wiring, improving the flexibility and maintainability of the system; in addition, the design connected to the wire transfer interface reduces the wear of the cable and the interface caused by multiple pluggings and unplugging, extending the service life of the cable and the interface. The stable connection method reduces the influence of mechanical stress on the cable and reduces the damage risk.

[0056] A silicone sheath for bundling multiple wire harnesses is provided at the end of the wire harness of the first output terminal 101.

[0057] The silicone sheath can tightly bundle multiple wire harnesses together, avoiding the situation where the wire harnesses are entangled with each other during the test. By keeping the wire harnesses neatly and orderly arranged, operators can connect and replace more conveniently, improving work efficiency and reducing the time waste caused by wire harness entanglement.

[0058] Embodiment 2

[0059] As Figure 1-2 shown, this embodiment provides a test device for a drag chain cable. The technical solution is similar to that of Embodiment 1, and the difference is that:

[0060] The first output terminal 101, the first input terminal 102, and the second output terminal 2014 are all provided with bull nose plugs 4.

[0061] Using the horn plug 4 can significantly simplify the installation and disassembly process of the wire harness, reduce the operation time and difficulty, improve the overall work efficiency, and facilitate the maintenance and replacement of the cable. At the same time, the horn plug design has good anti-vibration performance, can maintain a stable connection in a vibrating environment, avoid signal interruption or poor contact problems, and avoid signal transmission problems caused by vibration, ensuring the accuracy and continuity of test data.

[0062] The horn plug 4 is provided with a plurality of pins, and the pins are connected to the solder joints of the input end or the output end.

[0063] The horn plug 4 is also provided with a pin socket for facilitating the connection of the wire harness, and each pin hole on the pin socket corresponds to a pin one by one.

[0064] The horn plug 4 is also called an IDC plug and is usually connected to the second output end 2014 by welding. The horn plug 4 with fixed pins can be selected, and the fixed pins on the horn plug are welded to the solder joints on the second output end 2014.

[0065] The horn plug is provided with a pin socket for facilitating the connection of the wire harness, so that the wire harness can be directly inserted into the corresponding pin holes in the pin socket, simplifying the connection operation. The operator only needs to align and insert, without complex wiring steps, improving the connection efficiency. By using the pin socket, the operator can easily plug and unplug the wire harness without complex tools and welding operations, simplifying the maintenance process.

[0066] Embodiment 3

[0067] As Figure 1-2 shown, this embodiment provides a test device for a drag chain cable. The technical solution is similar to that of Embodiment 1, and the differences are as follows:

[0068] At the wire harness interfaces of the first output end 101 and the first input end 102, there are wire harness fixing clips for fixing the wire harness.

[0069] By adopting the above technical solution, the stability of the connection between the wire harness and the output end pins can be enhanced. The wire harness fixing clip can be installed on the horn plug, which can further strengthen the connection stability between the wire harness and the connector. The horn plug itself is used to connect multiple pins, and the fixing clip can ensure that these connections remain stable when subjected to external forces or vibrations, thus avoiding signal transmission problems caused by poor contact.

[0070] The inside of the PCB board fixing seat 2 is hollowed out, and through holes for facilitating the connection of the wire harness with the second input end 2013 are provided on both sides and the back.

[0071] By adopting the above technical solutions, the heat dissipation performance can be improved. The hollow design inside the PCB board fixing seat can effectively enhance air circulation, improve the heat dissipation performance, and prevent damage to electronic components caused by overheating. During the wire testing process of the PCB board, voltage and current tests of different magnitudes are required. Good heat dissipation performance helps the system maintain stability during long-term high-load operation and extends the service life of the equipment.

[0072] Meanwhile, the hollow design and through-hole settings simplify the installation and replacement process of the wire harness. Operators can conveniently introduce and fix the cables without complex tools and steps, reducing the time and difficulty of installation and maintenance and improving work efficiency.

[0073] Two fixing plates 3 are provided. One is used to fix the fixed-end test wire 31, and the other is used to fix the mobile-end test wire 32.

[0074] By adopting the above technical solutions, separating the fixing of the fixed-end and mobile-end test wires allows for more flexible configuration and adjustment of the length and layout of each group of cables to adapt to changes in different test requirements. This design improves the flexibility and adaptability of the system and can meet a wider range of application scenarios.

[0075] Meanwhile, when maintenance or cable replacement is needed, if the cables are mixed together, it is difficult for operators to quickly locate the cables that need to be processed, increasing the time and difficulty of maintenance. Fixing the fixed-end and mobile-end test wires on different fixing plates respectively enables operators to more conveniently identify and manage each group of cables and quickly perform maintenance or replacement; this design makes cable maintenance and replacement faster and more convenient, reduces the workload of operators, improves work efficiency, and lowers the maintenance difficulty.

[0076] One end of both the fixed-end test wire 31 and the mobile-end test wire 32 is provided with a unified interface connected to the wire transfer interface; the other end of the test wire is provided with several types of wiring ports to match different wire interfaces.

[0077] By adopting the above technical solutions, by setting a unified interface at one end of the fixed-end and mobile-end test wires, the connection operation is simplified and standardized, and the other end is matched with different wire interfaces as needed. During the testing process, different types of wire interfaces can lead to complex connection operations, increasing the operation difficulty and time cost. The unified interface design simplifies the operation steps, makes the connection operation faster and more efficient, reduces the complexity caused by a large variety of interface types, and improves the overall work efficiency. By adopting the unified interface design, the system can be compatible with and adapt to different wire interfaces, meet diverse test requirements, and improve the flexibility and application scope of the system.

[0078] In addition, during the use of the above embodiments, it is found that when connecting the wire harness of the second output end to the test wire connector of the fixed plate through the wire transfer interface, it takes a certain amount of time to replace the connection between the wire harness of the second output end and the wire interface multiple times. To further improve the operation efficiency of the device, the fixed plate can be removed. The wire harness can be directly connected in advance through the horn plug 4 of the second output end, and then directly connected to several different test ports through the wire harness. This can replace the above technical solution in which one end of the fixed-end test wire 31 and the mobile-end test wire 32 uses a unified interface. It can directly connect the test ports to both ends of the cable to be tested, improving the test efficiency for batch testing of various interface wires.

[0079] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
