Description

Technical Field

[0001] This utility model relates to the field of cable testing technology, and in particular to a signal cable continuity detector. Background Technology

[0002] Continuity testing of signal cables is a crucial step in the maintenance of communication systems, industrial automation, and electronic equipment, directly impacting the reliability of signal transmission and system stability. Currently, traditional signal cable testing relies primarily on simple testing tools such as multimeters and buzzers; however, this presents numerous challenges in long-distance cable testing.

[0003] 1. Use a multimeter to test:

[0004] The testing personnel first short-circuit the conductor to be tested at one end of the cable with the common conductor. Then, they proceed to the other end of the cable and use a multimeter probes to measure the connection between the conductor to be tested and the common conductor. The continuity of the cable is determined by the multimeter reading (e.g., resistance value): if the multimeter displays a low resistance value (close to 0Ω), the cable is conductive; if it displays infinity (or close to infinity), the cable is disconnected.

[0005] This testing method requires inspectors to run back and forth between the two ends of the cable, which is especially time-consuming and energy-intensive, especially in long-distance cable testing, resulting in extremely low testing efficiency.

[0006] 2. Use a buzzer for testing:

[0007] The tester first short-circuits the wire under test to the common wire at one end of the cable. Then, they proceed to the other end of the cable and use the probes at both ends of a buzzer to connect the wire under test to the common wire at the other end of the cable. If the cable is continuous, the buzzer will sound; if the cable is disconnected, there will be no sound.

[0008] This testing method requires inspectors to run back and forth between the two ends of the cable, which is especially time-consuming and energy-intensive, especially in long-distance cable testing, resulting in extremely low testing efficiency.

[0009] 3. Multi-person collaborative work:

[0010] One tester short-circuits the core wire to be tested with the common core wire of the cable at one end, while another tester operates a multimeter or buzzer at the other end of the cable to determine the continuity of the cable core wires, for example, by short-circuiting or disconnecting the core wire to be tested with the common core wire.

[0011] Collaborative work by multiple people requires good communication and coordination, which increases labor and communication costs. At the same time, multiple people working together can easily lead to errors, resulting in inaccurate test results and further reducing test efficiency.

[0012] There is an urgent need for a specialized tool that is simple in structure, safe and reliable, and suitable for detecting continuity in long-distance signal cables. Utility Model Content

[0013] The purpose of this invention is to provide a signal cable continuity detector that solves the problem of low efficiency in detecting continuity of long-distance signal cables. It has a simple structure and shortens the detection time.

[0014] To achieve the above objectives, this utility model employs the following technical solution:

[0015] A signal cable continuity detector includes a detector one and a detector two. Both detector one and detector two include a detection circuit. The detection circuit includes a detection circuit A and a detection circuit B. Detection circuit B is connected to detection circuit A through a detection terminal. One end of the cable under test is connected to detector one through detection terminal one, and the other end of the cable under test is connected to detector two through detection terminal two.

[0016] The detection circuit A includes indicator light 1 and resistor 1. Indicator light 1 and resistor 1 are connected in series. The other end of indicator light 1 is connected to the output terminal of the power switch. The other end of resistor 1 is connected to detection circuit B. The other end of resistor 1 is also connected to terminal a1 of detection terminal 1.

[0017] Each detection circuit B includes indicator light two, resistor two, detection switch one, and detection switch two. Indicator light two and resistor two are connected in series. The other end of indicator light two is connected to the output terminal of the power switch. The other end of resistor two is connected to terminal b1 of detection terminal one. One end of detection switch two is connected to terminal b2 of detection terminal two. The other end of detection switch two is connected to terminal a2 of detection terminal two.

[0018] The other end of resistor one is connected to one end of detection switch one, and the other end of detection switch one is connected to the other end of AC power supply.

[0019] One end of the cable under test is connected to terminal a1 and terminal b1 respectively, and the other end of the cable under test is connected to terminal a2 and terminal b2 respectively.

[0020] The cable under test consists of several signal cables covered with insulation layers. One end of the signal cable is connected to terminal a1 and terminal b1 respectively, and the other end of the signal cable is connected to terminal a2 and terminal b2 respectively.

[0021] One end of the switching power supply is connected to one end of the AC power supply.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] 1. One end of the signal cable is connected to detector one via a cable connector, and the other end is connected to detector two via a cable connector. This allows for quick connection and disconnection between the cable under test and the detectors. In long-distance cable testing, testers often need to replace the cable under test frequently. Using connectors avoids cumbersome wiring processes, reduces testing errors caused by wiring mistakes, and saves a significant amount of wiring time.

[0024] 2. The testing personnel can operate the detection switch on the closed detector and display the test results of the cable under test through the indicator light. This enables single-person long-distance cable testing without the need for the testing personnel to run back and forth between the two ends of the cable or for multiple people to work together, thus improving testing efficiency.

[0025] 3. A detection switch is installed in the detection circuit to prevent detection personnel from directly contacting the cable conductor, effectively preventing accidental electric shock accidents and protecting the personal safety of monitoring personnel. Attached Figure Description

Detector one and detector two each include detection terminal one, detection terminal two, and detection circuits with identical structures. The detection circuits include detection circuit A, detection circuit B, detection circuit C, detection circuit D, detection circuit E, and detection circuit F. Detection circuit A includes an indicator light S and a resistor R1 connected in series, and detection circuit B includes an indicator light connected in series. B consists of a resistor R2, a detection switch KA, and a detection switch KB. The other end of resistor R1 is connected to terminal a1 of detection terminal one in detector one, and the other end of detection switch KA is connected to the other end of the AC 220V power supply. One end of detection switch KB is connected to terminal a2 of detection terminal two in detector two, and the other end of detection switch KB is connected to terminal b2 of detection terminal two in detector two. The other end of resistor R2 is connected to terminal b1 of detection terminal one in detector one. Detection circuit C includes an indicator light C, a resistor R3, and a detection switch KC connected in series. One end of detection switch KC is connected to terminal a2 of detection terminal two in detector two. The other end of the detection switch KC is connected to terminal c2 of detection terminal two in detector two, and the other end of the resistor R3 is connected to terminal c1 of detection terminal one in detector one; the detection circuit D includes an indicator light D, a resistor R4, and a detection switch KD connected in series. One end of the detection switch KD is connected to terminal a2 of detection terminal two in detector two, and the other end of the detection switch KD is connected to terminal d2 of detection terminal two in detector two. The other end of the resistor R4 is connected to terminal d1 of detection terminal one in detector one; the detection circuit E includes an indicator light E, a resistor R5, and a detection switch KE connected in series. One end of the detection switch KE is connected to terminal a2 of detection terminal two in detector two, and the other end of the detection switch KE is connected to terminal c1 of detection terminal one in detector one. The other end of the resistor R5 is connected to terminal e2 of the second detection terminal in detector 2, and the other end of the resistor R5 is connected to terminal e1 of the first detection terminal in detector 1; the detection circuit F includes an indicator light F and a resistor R6 connected in series, and a detection switch KF. One end of the detection switch KF is connected to terminal a2 of the second detection terminal in detector 2, and the other end of the detection switch KF is connected to terminal f2 of the second detection terminal in detector 2. The other end of the resistor R6 is connected to terminal f1 of the first detection terminal in detector 1; the other ends of the indicator lights S, B, C, D, E, and F are all connected to the output terminal of the power switch Q, which is a 1P circuit breaker;A fuse FU2 is connected between indicator light S and power switch Q, and a fuse FU1 is connected between the other end of detection switch KA and AC 220V power supply.

[0032] The cable under test consists of six signal cables covered with insulation. One end of the signal cable is connected to terminals a1, b1, c1, d1, e1, and f1 of the first detection terminal in the first detector through the male connector of cable connector one. The other end of the signal cable is connected to terminals a2, b2, c2, d2, e2, and f2 of the second detection terminal in the second detector through the male connector of cable connector two.

[0033] Work process:

[0034] The detector consists of Detector 1 and Detector 2, each equipped with multiple detection terminals for connecting the two ends of the signal cable under test. Detector 1 and Detector 2 achieve signal transmission and detection at both ends of the cable through corresponding connection terminals. Assuming the white and brown core wires in the signal cable need to be tested, the specific steps are as follows: Connect one end of the white core wire to terminal a1 of Detector 1; connect the other end of the white core wire to terminal a2 of Detector 2; connect one end of the brown core wire to terminal b1 of Detector 1; connect the other end of the brown core wire to terminal b2 of Detector 2; close the power switch Q to provide power to the detector, close the detection switch KA to start the detection process; if indicator lights S and B light up simultaneously, it indicates that both the white and brown core wires have passed the test, the cable circuit is normal, and there is no short circuit or open circuit. Assuming we need to test the red and black core wires in a signal cable, the specific steps are as follows: Connect one end of the red signal cable to terminal c1 of test terminal one in detector one; connect the other end of the red core wire to terminal c2 of test terminal two in detector two; connect one end of the black core wire to terminal d1 of test terminal one in detector one; connect the other end of the black core wire to terminal d2 of test terminal two in detector two; close the power switch Q to provide power to the detector, close the test switch KA to start the testing process. If indicator light S lights up, but indicator light B does not light up, it means that at least one of the red or black core wires in the cable has failed the test.

[0035] This invention relates to a signal cable where one end connects to detector one via a cable connector, and the other end connects to detector two via a cable connector. This enables rapid connection and disconnection between the cable under test and the detectors. In long-distance cable testing, testing personnel often need to frequently replace the cable. Using connectors avoids the cumbersome wiring process, reduces testing errors caused by wiring mistakes, and saves significant wiring time. Testing personnel can operate the closed detection switch on the detector, and the indicator light displays the testing results of the cable under test, enabling single-person long-distance cable testing without the need for personnel to run back and forth between the two ends of the cable or for multiple people to work together, thus improving testing efficiency. The detection switch in the detection circuit prevents testing personnel from directly contacting the cable conductor, effectively preventing accidental electric shock accidents and protecting the personal safety of monitoring personnel.
