Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, in particular to a portable quick detection device for cables. Background Art

[0002] During production and use, cables require tests for conductor DC resistance, insulation resistance, resistivity, finished product voltage, and inter-insulated core voltage. These tests can promptly identify potential cable faults and defects, preventing power and communication interruptions caused by cable failures. DC resistance and resistivity testing help extend cable life, reduce replacement and repair costs, and improve the stability of power and communication systems. Cable testing also provides feedback for cable design and manufacturing, promoting continuous improvement in product quality.

[0003] However, the traditional cable testing equipment currently used to measure the DC resistance and resistivity of conductors has a relatively fixed structure and poor flexibility. In order to meet the needs of cable testing, the overall length is still relatively long, which makes it inconvenient to carry. In addition, it is also relatively complicated to connect the test line, which can no longer meet the needs of current rapid testing personnel. Therefore, a portable rapid testing device for cables is needed. Utility Model Content

[0006] Optionally, a connecting handle is installed on the same side of the two placement plates through long bolts.

[0008] Optionally, a plug hole is provided on the other side of the current detection clamp and the potential detection clamp, a connecting plug board is plugged into the inside of the plug hole, and a detection line is provided on one side of the connecting plug board.

[0009] Optionally, both ends of the connecting wire are provided with mounting rings, one end of the fixing bolt passes through the mounting ring and is threadedly connected to the current detection clamp or the potential detection clamp and abuts against the connecting plug board.

[0010] Optionally, the inner walls of the fixed sleeve rod and the sliding tube are both provided with damping soft sleeves, and the bottom of the placement plate is provided with an anti-slip soft pad.

[0011] The utility model provides a portable quick inspection device for cables, which has the following beneficial effects:

[0012] The portable quick-testing device for cables can shrink its overall size when carried, thereby facilitating portability, by providing a fixed sleeve rod and a telescopic rod. The sliding tube allows the current detection clamp and the potential detection clamp to be flexibly adjusted in position, thereby better detecting the cable. The long bolts and the connecting handle cooperate to bolt the retracted placement plate, thereby effectively preventing the telescopic rod from automatically expanding when carried. The plug-in hole, the connecting plug plate, and the detection line facilitate the operator's installation of the connection detection line, thereby shortening the overall detection time.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] See also Figures 1 to 4The utility model provides a technical solution: a portable quick detection device for cables, comprising two placing flat plates 1, the bottom of the placing flat plates 1 is provided with a non-slip soft pad to increase the friction of placement and protect the placing flat plates 1, in order to effectively prevent the retracted telescopic rod 4 from unfolding by itself when carrying, a connecting handle 12 is installed on the same side of the two placing flat plates 1 through a long bolt 11, so as to bolt the two placing flat plates 1 that are close to each other after retraction, and the top of the two placing flat plates 1 is provided with a mounting block 2, one side of the mounting block 2 is provided with a fixed sleeve rod 3, the interior of the fixed sleeve rod 3 is plugged with the telescopic rod 4, and the setting of the fixed sleeve rod 3 and the telescopic rod 4 can make the overall size of the device shrink when carried, so as to facilitate carrying, and the surfaces of the fixed sleeve rod 3 and the telescopic rod 4 are provided with a scale 13 to ensure that the current detection clamp 8 and the potential detection clamp 9 move accurately into place;

[0020] The surface of the fixed sleeve rod 3 is sleeved with a sliding tube 5. The inner walls of the fixed sleeve rod 3 and the sliding tube 5 are provided with a damping soft sleeve 18 to increase the resistance of the fixed sleeve rod 3 and the sliding tube 5 to prevent them from moving too flexibly, resulting in automatic movement due to uneven placement during use. The top of the sliding tube 5 and the mounting block 2 are both provided with a slide plate 6. An operating turntable 7 is provided on one side of the slide plate 6. The current detection clamp 8 and the potential detection clamp 9 are driven by the operating turntable 7 to clamp the cable. The top of the slide plate 6 is slidably connected to the current detection clamp 8 and the potential detection clamp 9. It can be seen from the figure that the potential The voltage segment contact point of the detection clamp 9 should be small, especially when testing low-resistance wires. The current segment contact surface of the current detection clamp 8 should be large and tight. The cable is contacted through the current detection clamp 8 and the potential detection clamp 9. The two current detection clamps 8 clamping positions are the high current end and the low current end respectively, and the two potential detection clamps 9 clamping positions are the high voltage end and the low voltage end respectively. Then turn on the power of the DC resistance tester. After the reading on the panel stabilizes, the data value displayed is the measured resistance.

A detection line 17 is provided on one side of the connecting plug plate 16. One end of the fixing bolt 14 passes through the mounting ring and is threadedly connected to the current detection clamp 8 or the potential detection clamp 9 and abuts on the connecting plug plate 16. When in use, the connecting plug plate 16 connected to one end of the detection line 17 can be directly inserted into the plug hole 15, and then the fixing bolt 14 is tightened so that the front end of the fixing bolt 14 abuts against the plug hole 15 to connect the DC resistance tester;

Both ends of the connecting wire 10 are provided with mounting rings to facilitate the fixing bolt 14 to install the connecting wire 10 on the current detection clamp 8 and the potential detection clamp 9.

[0023] In the present invention, the working steps of the device are as follows:

[0024] First, remove one of the long bolts 11 on the connecting handle 12, then unfold the telescopic rod 4 according to the length of the detection cable, and then rotate the operating dial 7 to drive the current detection clamp 8 and the potential detection clamp 9 to clamp the stripped cable;

[0025] Then insert the connecting plate 16 connected to one end of the detection line 17 of the DC resistance tester into the plug hole 15, and then tighten the fixing bolt 14 so that the front end of the fixing bolt 14 is against the connecting plate 16 to connect and fix;

[0026] The two current detection clamps 8 are clamped at the current high end and the current low end respectively, and the two potential detection clamps 9 are clamped at the voltage high end and the voltage low end respectively. Then, the power supply of the DC resistance tester is turned on to perform resistance detection.

[0027] When measuring micro-ohm resistance, you can measure the forward current once, record the test result, and then measure the reverse current once, record the test result. The average of the two values ​​is the resistance value of the object being measured.
