Description

Technical Field

[0001] The utility model relates to the technical field of cable testing, in particular to a comprehensive test bench for cable testing. Background Art

[0002] Cable environmental stress screening tests are a crucial component of cable production. Only cables that pass these rigorous tests are considered qualified. The cable vibration test, a key component of this testing, simulates the various vibrations to which cables are subjected during actual use. The test then analyzes and detects defective components, poor workmanship, and welding defects.

[0003] Existing cable vibration tests typically involve first vibrating the cable, then removing it for testing. This approach has the following drawbacks: some cable faults only occur during vibration and return to normal operation after the vibration ends. Therefore, the vibration-first, then-test method cannot detect these faults. Consequently, missed detection of these faults can ultimately lead to cable failures during actual use if vibration is present, impacting normal cable operation. Utility Model Content

[0023] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0024] In the description, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance. It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, removable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms based on specific circumstances.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 This embodiment provides a comprehensive cable test bench, including a vibration table 1, a cable bracket 2, a transient break detector 3, a transfer cable 4 and a controller 5.

[0028] The vibration table 1 is an existing mature structure, and is mainly used to output vibrations to simulate various vibration factors to which the product is subjected during actual use, thereby identifying whether the product has the ability to withstand environmental vibrations.

[0029] The cable support 2 is fixed on the output end of the vibration table 1 , and the cable support 2 is provided with a socket 21 for plugging in the connector of the cable to be tested.

[0030] It should be noted that the cable bracket 2 can be fixedly connected to the output end of the vibration table 1 by using bolts, buckles or other common connection structures.

[0031] Specifically, the cable support 2 is provided with a plurality of sockets 21, which can be used for simultaneous detection of a plurality of cables under test. Figure 1 There are four sockets 21 shown in FIG.

[0032] The cable holder 2 of this embodiment is provided with a socket 21 adapted to the cable connector. During testing, the tested cable is plugged into the socket 21 through its connector to achieve electrical connection between the tested cable and the buckle.

[0033] Specifically, the socket 21 can be adapted to the cable to be tested. The socket 21 adapted to the cable connector is a mature structure, and the selection of the socket 21 model is also easy to design by those skilled in the art, which will not be described here.

[0034] It should be noted that the socket 21 can be installed on the cable holder 2 in a detachable manner such as bolts. When replacing the cable under test, just replace the socket 21; it can also be installed on the cable holder 2 in a non-detachable manner such as welding or interference fit. When replacing the cable under test, just replace the cable holder 2.

[0035] The instantaneous interruption detector 3 is provided with a detection port 31 .

[0036] It should be noted that the instantaneous power failure detector 3 is a mature existing structure, such as that shown in patent publication number CN103399287A or announcement number CN204495940U. The instantaneous power failure detector 3 primarily determines whether the tested product has experienced a momentary power failure by measuring the resistance value in the circuit formed between the detector and the tested product. It is particularly suitable for detecting faults in the tested cable that only occur when the tested cable is vibrating.

[0037] Specifically, this embodiment uses the NMS10 super transient tester 3 produced by NAC, which can determine the resistance value range from 1Ω to 5KΩ and the transient test amplitude from 0.1μs to 99.9μs.

[0038] Specifically, the instantaneous disconnection detector 3 is provided with a plurality of detection ports 31, which correspond one to one with the sockets 21 and can be used for simultaneous detection of a plurality of cables under test. Figure 1 As shown in FIG, there are four detection ports 31 .

[0039] The two ends of the adapter cable 4 are electrically connected to the socket 21 and the detection port 31 respectively.

[0040] It is easy to understand that the electrical connection between the adapter cable 4 and the plug buckle or the detection port 31 can be achieved by using a connector or a wire connection.

[0041] Specifically, the adapter cable 4 includes a first adapter harness 41 and a second adapter harness 42. One end of the first adapter harness 41 is respectively connected to a plurality of sockets 21, and the other end of the first adapter harness 41 is integrated with an adapter male connector 43. One end of the second adapter harness 42 is respectively connected to a plurality of detection ports 31, and the other end of the second adapter harness 42 is integrated with an adapter female connector 44. The adapter male connector 43 is connected to the adapter female connector 44. When in use, it is only necessary to connect the adapter male connector 43 to the adapter female connector 44, which makes the operation more convenient. In this embodiment, by adding the adapter male connector 43 and the adapter female connector 44, it is only necessary to connect the adapter male connector 43 and the adapter female connector 44 when connecting, and there is no need to connect the sockets 21 to the detection ports 31 one by one, which greatly improves the detection efficiency. At the same time, since the number of connections is reduced, the probability of connection errors is also reduced.

[0042] The controller 5 is in communication with the momentary break detector 3 and is used to receive and analyze the detection signal of the momentary break detector 3. When in use, the momentary break detector 3 collects the signal of the tested cable, and the controller 5 receives and analyzes the signal and outputs the result.

[0043] Furthermore, the cable test integrated test bench further comprises a printer 6, which is communicatively connected to the controller 5. After the test is completed, the tester can control the printer 6 through the controller 5 to print the test results, which is more conducive to the tester's processing of the test results.

[0044] Furthermore, the cable test bench further includes a cabinet 7, in which the instantaneous disconnection detector 3, the controller 5, and the printer 6 are all installed. The instantaneous disconnection detector 3, the controller 5, and the printer 6 are all integrated into the cabinet 7 to form an integral structure, which is more convenient to install and transport.

[0045] Furthermore, universal wheels 8 are installed at the bottom of the cabinet 7 to facilitate movement.

[0046] The working principle of the cable test comprehensive test bench of this embodiment is as follows:

[0047] First, select a cable holder 2 equipped with a socket 21 that matches the connector of the cable to be tested, plug the connector of the cable to be tested into the socket 21, and then connect the male adapter 43 and the female adapter 44 to perform the test; during the test, the signal of the cable to be tested is collected by the momentary break detector 3, and the signal is received and analyzed by the controller 5 to output the result; after the test, the controller 5 outputs instructions to control the printer 6 to print the test results.

[0048] The above is only a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions have been made with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and these modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the technical solutions of the embodiments, and they should all be covered by the scope of protection of the claims.
