Description

Technical Field

[0001] The present application relates to the technical field of terminal block wiring test, and in particular to a terminal block wiring test device. Background Art

[0002] The control cabinet of the power system is usually provided with a terminal block, which has multiple mutually insulated wiring terminals. The control cabinet is connected to the external device through the wiring terminals. When conducting a wiring test on the terminal block, the tester needs to insert the test line connector into different wiring terminals. In this process, due to the operating error of the tester, the wiring between the test line connector and the wiring terminal may be loose, which may lead to inaccurate test results. Summary of the invention

[0003] Based on this, it is necessary to provide a terminal block wiring test device to address the problem that the wiring between the test line connector and the wiring terminal is not tight due to the operating error of the tester, which leads to inaccurate test results.

[0004] The technical solution is as follows:

[0005] One embodiment provides a terminal block wiring test device, including:

[0006] A first clamping mechanism, wherein the first clamping mechanism has a first holding end and a power connection end which are arranged opposite to each other, the power connection end is provided with a power connection piece, the power connection piece is used to be assembled with a wiring terminal, and the first clamping mechanism is provided with a first rotating part;

When the electrical measuring mechanism detects that no current passes through the power connection piece, it means that the connection between the power connection piece and the wiring terminal is not tight enough. The staff then adjusts the power connection piece to ensure the tightness of the connection between the power connection piece and the wiring terminal. Compared with traditional technology, the above-mentioned terminal block wiring test device can ensure the tightness of the connection between the test line and the wiring terminal through the abutment of the clamping end against the outer wall of the wiring terminal and the detection result of the electrical measuring mechanism, thereby ensuring the accuracy of the test result.

[0032] See also Figures 1 to 3One embodiment of the present application provides a terminal block wiring test device, including a first clamping mechanism 100, a second clamping mechanism 200, an electric measuring mechanism 300 and a wiring mechanism 400, wherein the first clamping mechanism 100 has a first gripping end 111 and a power connection end 112 arranged opposite to each other, the power connection end 112 is provided with a power connection piece 500, and the power connection piece 500 is used to be assembled with a wiring terminal, the first clamping mechanism 100 is provided with a first rotating part 113; the second clamping mechanism 200 has a first holding ... The second holding end 211 and the clamping end 212 are arranged, and the second clamping mechanism 200 is provided with a second rotating part 213, and the second rotating part 213 is rotatably connected to the first rotating part 113 so that the power connection end 112 can be close to or away from the clamping end 212; the power measuring mechanism 300 is electrically connected to the power connection piece 500, and the power measuring mechanism 300 is used to detect whether there is current passing through the power connection piece 500; the wiring mechanism 400 is electrically connected to the power connection piece 500, and the wiring mechanism 400 is used to be assembled with the test line.

[0033] When the terminal block wiring test device is used, the tester first assembles the test line with the wiring mechanism 400, and the test line is electrically connected to the power connection piece 500 through the wiring mechanism 400, and then the power connection piece 500 of the power connection end 112 is connected to the wiring terminal. The tester controls the mutual movement between the first gripping end 111 and the second gripping end 211 to make the power connection end 112 close to the clamping end 212, so that the clamping end 212 abuts against the outer wall of the wiring terminal to prevent the power connection piece 500 from moving relative to the wiring terminal. At this time, when the electrical measurement mechanism 300 detects that current passes through the power connection piece 500, , it means that the connection between the power connection piece 500 and the terminal is tight. When the power measuring mechanism 300 measures that no current passes through the power connection piece 500, it means that the connection between the power connection piece 500 and the terminal is not tight enough. The staff will then adjust the power connection piece 500 to ensure the tightness of the connection between the power connection piece 500 and the terminal. Compared with the conventional technology, the terminal block wiring test device can ensure the tightness of the connection between the test line and the terminal through the abutment of the clamping end 212 against the outer wall of the terminal and the detection result of the power measuring mechanism 300, thereby ensuring the accuracy of the test result.

[0034] As an explanation, the terminal block on the control cabinet includes a plurality of wiring terminals arranged in a vertical direction (i.e., the direction of gravity). When conducting a wiring test on the terminal block, the tester needs to insert the plug of the test line into different wiring terminals. During this process, due to the large number of wiring terminals and their dense arrangement, a long period of testing will cause the tester's operating error rate to increase, thereby causing the connector of the test line not to be inserted to the triggering depth of the wiring terminal, resulting in the wiring between the power connection piece 500 and the wiring terminal not being tight enough, affecting the test results. In the present application, the electrical measuring mechanism 300 is used to detect whether current passes through the power connection piece 500 after it is inserted into the wiring terminal, thereby ensuring the tightness of the wiring between the power connection piece 500 and the wiring terminal and improving the accuracy of the test results.

[0035] Furthermore, in order to prevent the test personnel from inserting the power connection piece 500 into the terminal block and accidentally touching the terminal block wiring test device, resulting in the power connection piece 500 not being tightly connected to the terminal block, the staff can operate the first gripping end 111 and the second gripping end 211 to control the clamping end 212 to be close to the power connection end 112, so that the clamping end 212 can abut against the outer wall of the terminal block. At this time, the power connection piece 500 and the clamping end 212 can respectively abut against the inside and outside of the terminal block and generate friction, ensuring a stable connection between the terminal block wiring test device and the terminal block.

[0036] Optionally, the electric current measuring mechanism 300 may be a resistive current detecting element, a current transformer, a Hall element, etc., which is not specifically limited here.

[0037] Furthermore, the wiring mechanism 400 is provided with a wiring hole. When in use, the tester first inserts the plug of the test line into the wiring hole to achieve electrical connection between the test line and the power connection piece 500.

[0038] Optionally, in some embodiments, the first clamping mechanism 100 and the second clamping mechanism 200 can be cross-connected and rotatably connected to each other (that is, the first clamping mechanism 100 and the second clamping mechanism 200 cross to form an X shape), when the tester controls the first gripping end 111 to approach the second gripping end 211, the power connection end 112 can also approach the clamping end 212, and when the tester controls the first gripping end 111 to move away from the second gripping end 211, the power connection end 112 can also move away from the clamping end 212; in other embodiments, as shown in the drawings of the specification Figure 1 to Figure 2As shown, the first clamping mechanism 100 and the second clamping mechanism 200 are both bent (that is, the first clamping mechanism 100 and the second clamping mechanism 200 are both V-shaped), the first rotating portion 113 is arranged at the bending portion of the first clamping mechanism 100, and the second rotating portion 213 is arranged at the bending portion of the second clamping mechanism 200. The first rotating portion 113 located at the bending portion of the first clamping mechanism 100 is rotatably connected to the second rotating portion 213 located at the bending portion of the second clamping mechanism 200. When the tester controls the first holding end 111 to approach the second holding end 211, the power connecting end 112 is away from the clamping end 212. When the tester controls the first holding end 111 to move away from the second holding end 211, the power connecting end 112 is close to the clamping end 212.

[0039] Furthermore, the staff can control the power connection end 112 and the clamping end 212 to move closer to or farther from each other by holding the first holding end 111 and the second holding end 211, which saves effort.

[0040] See also Figures 1 to 3 In one embodiment, the first clamping mechanism 100 includes a first clamping member 110, the first clamping member 110 has a first holding end 111 and a power connection end 112 that are oppositely arranged, the first rotating portion 113 is arranged on the first clamping member 110 and is located between the first holding end 111 and the power connection end 112, the first clamping member 110 is provided with a first installation cavity and a first opening 114 that are connected, the first opening 114 is opened at the power connection end 112, the power connection member 500 includes a first conductive portion 510 and a power connection portion 520, the first conductive portion 510 is arranged in the first installation cavity and is electrically connected to the wiring mechanism 400, the power connection portion 520 is connected to the first conductive portion 510 and is passed through the first opening 114, and the power connection portion 520 is used to be assembled with the wiring terminal.

[0041] When the test line is assembled with the wiring mechanism 400, the test line can pass through the wiring mechanism 400, the first conductive part 510 and the power connection part 520 in sequence to achieve electrical connection with the wiring terminal. The first conductive part 510 is arranged in the first installation cavity, which can not only protect the first conductive part 510, but also prevent the staff from accidentally touching the first conductive part 510 and causing safety hazards. The power connection part 520 connected to the first conductive part 510 is passed through the first opening 114 to achieve assembly with the wiring terminal, so that the overall structure of the terminal block wiring test device is compact.

[0042] In one embodiment, the first conductive portion 510 includes a first conductive sheet, and the shape of the first conductive sheet matches the shape of the interior of the first mounting cavity, so as to facilitate fixing the first conductive sheet in the first mounting cavity.

[0043] Furthermore, the first conductive sheet is fixed to the inside of the first installation cavity by a threaded component, so the implementation cost is low and the fixing effect is reliable.

[0044] In one embodiment, the power connection portion 520 includes a spring pin, which has a certain elastic force and can better contact the connection terminal.

[0045] See also Figure 3 In one embodiment, the electrical measuring mechanism 300 includes a resistor element 310, a neon tube 320 and a grounding element 330. The resistor element 310 is disposed in the first installation cavity and electrically connected to the power connection portion 520. The neon tube 320 is electrically connected to the resistor element 310. The first clamping member 110 also has a first contact window 115 connected to the first installation cavity. The grounding element 330 is electrically connected to the neon tube 320 and is passed through the first contact window 115.

[0046] During use, the tester touches the grounding element 330. When current flows through the power connection part 520, the current will pass through the resistance element 310, the neon tube 320, the grounding element 330 and the tester in sequence, and finally flow to the ground to form a loop. When there is current in the terminal, there is a certain potential difference between the terminal and the ground. At this time, the neon tube 320 will glow, otherwise the neon tube 320 will not glow. The tester can confirm whether current flows through the power connection part 520 by observing the glow of the neon tube 320, and then confirm the tightness of the connection between the test line and the terminal, and the implementation process is convenient.

[0047] By way of explanation, the neon tube 320 has neon gas therein, and when the voltage of the neon tube 320 reaches a certain value, the neon gas is ionized and generates a glow effect, so that the neon tube 320 emits light.

[0048] Furthermore, the power testing range of the neon tube 320 is 50V-500V. For alternating current, the two poles of the neon tube 320 emit light, and for direct current, the neon tube 320 emits light in one pole.

[0049] In one embodiment, the power connection portion 520 and the contact element 300 are both made of conductive metal materials.

[0050] See also Figures 1 to 3 In one embodiment, the first clamping mechanism 100 further includes a first insulating sleeve 120 , which is sleeved outside the first clamping member 110 and has a second contact window 121 , and the second contact window 121 is arranged corresponding to the first contact window 115 .

[0051] The first insulating sleeve 120 sleeved on the outside of the first clamping member 110 can prevent the staff from electric shock. The second contact window 121 is arranged corresponding to the first contact window 115. In this way, the staff can touch the grounding element 330 through the second contact window 121 and the first contact window 115 in turn, thereby improving the safety and convenience of using the terminal block wiring test device.

[0052] In one embodiment, the side wall of the first clamping member 110 is further provided with a first installation opening connected to the first installation cavity, so that the resistor element 310, the neon tube 320, the grounding element 330 and the power connection member 500 can be installed into the first installation cavity through the first installation opening.

[0053] See also Figure 1 and Figure 3 In one embodiment, the first clamping member 110 is provided with at least two positioning portions 116 , all of the positioning portions 116 are arranged at intervals along the circumference of the first contact window 115 , and the positioning portions 116 abut against the inner wall of the second contact window 121 .

[0054] Such a configuration can ensure accurate alignment between the first contact window 115 and the second contact window 121 , prevent the tester from being unable to touch the grounding element 330 through the second contact window 121 , and improve the reliability of the first insulating sleeve 120 and the first gripping member.

[0055] See also Figure 2 In one embodiment, the first insulating sleeve 120 is provided with an observation hole 122 , and the observation hole 122 is arranged corresponding to the neon tube 320 .

[0056] With such arrangement, the light emitted by the neon tube 320 can be transmitted through the observation hole 122 , so that the tester can judge whether current flows through the power connection piece 500 after the power connection piece 500 is inserted into the connection terminal.

[0057] Furthermore, the neon tube 320 is provided with a light-emitting portion, and the light-emitting portion of the neon tube 320 is passed through the observation hole 122, so that the tester can observe whether the light-emitting portion emits light, and then determine whether current passes through the power connection component 500 after being inserted into the connection terminal.

[0058] See also Figures 1 to 3 In one embodiment, the second clamping mechanism 200 includes a second clamping member 210, the second clamping member 210 has a second holding end 211 and a clamping end 212 that are oppositely arranged, the second rotating portion 213 is arranged on the second clamping member 210 and is located between the second holding end 211 and the clamping end 212, the second clamping member 210 is provided with a second installation cavity 214 and a second opening 215, and the second opening 215 is opened at the clamping end 212, the terminal block wiring test device also includes a clamping member 600, the clamping member 600 includes a second conductive portion 610 and a clamping portion 620, the second conductive portion 610 is arranged in the second installation cavity 214, the clamping portion 620 is connected to the second conductive portion 610 and is passed through the second opening 215, the wiring mechanism 400 is electrically connected to the second conductive portion 610, and the second conductive portion 610 is electrically connected to the first conductive portion 510.

[0059] When the test line is assembled with the wiring mechanism 400, the test line can pass through the wiring mechanism 400, the second conductive part 610, the first conductive part 510 and the power connection part 520 in sequence to achieve electrical connection with the wiring terminal. The second conductive part 610 is arranged in the second installation cavity 214, which can not only protect the second conductive part 610, but also prevent the staff from accidentally touching the second conductive part 610 and causing safety hazards. The clamping part 620 is passed through the second opening 215 and can abut the outer wall of the wiring terminal. While ensuring a stable connection between the terminal block wiring test device and the wiring terminal, it can also make the overall structure of the terminal block wiring test device compact.

[0060] In one embodiment, the clamping portion 620 is provided with a plurality of friction protrusions arranged at intervals to increase the friction between the clamping portion 620 and the outer wall of the terminal block, further ensuring a stable connection between the terminal block wiring test device and the terminal block.

[0061] Furthermore, the power connection piece 500 is also provided with a clamping fitting portion, which is connected to the power connection portion 520, and the clamping fitting portion can cooperate with the clamping portion 620 to respectively abut against the inside and outside of the terminal block and generate friction, thereby ensuring a stable connection between the terminal block wiring test device and the terminal block.

[0062] Furthermore, the clamping portion 620 and the clamping mating portion are mutually meshing and mating shark clamp structures.

[0063] See also Figure 3 In one embodiment, the terminal block wiring test device further includes a mounting shaft 710 and a torsion spring 720, the first rotating portion 113 is provided with a first mounting hole, the second rotating portion 213 is provided with a second mounting hole, the mounting shaft 710 is passed through the first mounting hole and the second mounting hole, the torsion spring 720 is sleeved on the outer wall of the mounting shaft 710, one end of the torsion spring 720 abuts against the first conductive portion 510 and is electrically connected to the first conductive portion 510, and the other end of the torsion spring 720 abuts against the second conductive portion 610 and is electrically connected to the second conductive portion 610.

[0064] The torsion spring 720 can use its own elasticity to abut the first conductive part 510 and the second conductive part 610, so that the power connection end 112 and the clamping end 212 tend to approach each other, ensuring a stable connection between the terminal block wiring test device and the wiring terminal; in addition, the torsion spring 720 can also play a conductive role. When the test line is assembled with the wiring mechanism 400, the test line can pass through the wiring mechanism 400, the second conductive part 610, the torsion spring 720, the first conductive part 510 and the power connection part 520 in sequence to achieve electrical connection with the wiring terminal, and then the terminal block can be tested through the terminal block wiring test device.

[0065] Furthermore, since the internal installation space of the first clamping member 110 and the second clamping member 210 is limited, in order to ensure the compactness of the overall structure of the terminal block wiring test device, in this embodiment, the first conductive part 510 and the second conductive part 610 are respectively arranged in the first installation cavity and the second installation cavity 214, and the electrical connection between the first conductive part 510 and the second conductive part 610 is achieved through a coil spring.
