[0034] When detecting the variable quantity of copper stranded wire flexible connections, it is necessary to cut a certain unit length of stranded wire. During the process of cutting the copper wire, the cut end of the copper wire needs to be wrapped and fixed. However, when it is necessary to cut copper wires of different lengths, the fixing device at the end of the copper wire is difficult to move, and the middle part of the cut copper wire may come into contact with the outside world, which will cause certain errors in the electrical variable detection.

[0035] To this end, the present invention provides a flat copper stranded wire flexible connection electrical variable detection device and detection method, see Figure 1-6 As shown, it includes an intercepting platform 1, which is characterized in that: a plurality of groups of slide grooves 2 are opened in the middle of the intercepting platform 1, and the middle of the plurality of slide grooves 2 are all slidably connected with slide pads 3, the ends of the slide pads 3 are provided with clamping mechanisms, and a stretching mechanism is provided in the middle of the intercepting platform 1.

[0036] When it is necessary to detect the variable quantity, the copper stranded wire can be placed inside the clamping mechanism, and then the sliding pad 3 can be slid in the middle of the slide groove 2 through the stretching mechanism, thereby stretching the two ends of the clamping mechanism, thereby reducing the pulling of the copper stranded wire inside the clamping mechanism, and making the copper stranded wire in a straight state, thereby reducing the contact between the copper stranded wire and the intercepting platform 1 when performing electrical variable detection, and reducing the occurrence of inaccurate variable quantity detection results due to external factors.

[0037] For details, see Figure 1-6 As shown, the clamping mechanism includes a cross bar 4, a support pad 5, a fastening ring 6, a steel cable 7, a hook-shaped channel 8, a first rack plate 9, and a starting assembly.

The connecting and fixing plate 10 is fixedly connected to the side of the cross bar 4, the first servo motor 11 is fixedly connected to the middle of the connecting and fixing plate 10, and the first gear 12 is fixedly connected to the end of the first servo motor 11. The first gear 12 is engaged with the first rack plate 9.

[0040] The stretching mechanism includes a second servo motor 17, a second gear 18, a second rack plate 19, and a baffle 20. The second servo motor 17 is fixedly connected to the middle of the intercepting platform 1, and the output end of the second servo motor 17 is fixedly connected to the second gear 18. Multiple groups of second rack plates 19 are meshed in the middle of the second gear 18. The ends of the second rack plates 19 are fixedly connected to the cross bar 4, and a baffle 20 is fixedly connected to the ends of one group of second rack plates 19.

[0041] The middle of the plurality of crossbars 4 is slidably connected with a slide bar 21 , which is located on a side away from the stretching mechanism. The end of the fastening ring 6 is fixed with a guide opening 22 .

[0042] During operation, when the copper stranded wire needs to be cut off, it can be placed inside the fastening ring 6, and then the first rack plate 9 can be pulled by the stretching component, thereby driving the steel cable 7 to slide inside the hook-shaped channel 8. When the steel cable 7 is pulled, the fastening ring 6 can be contracted, and then the copper stranded wire can be fixed when it needs to be cut off, thereby reducing the situation in which the copper stranded wire slides during the cutting process and causes the cutoff part to become loose, and reducing the situation in which the detection result is inaccurate due to the loose copper stranded wire. When the first rack plate 9 is pulled to make the steel cable 7 slide in the middle of the hook-shaped channel 8, the steel cable 7 can be fixed. During sliding, the first trapezoidal plate 13 can be driven to slide by the steel cable 7, and then the first trapezoidal plate 13 can push the second trapezoidal plate 16 upward, so that the conical spring 15 is contracted, and then the limit pin 14 in the middle of the second trapezoidal plate 16 can rise upward from the middle of the cross bar 4, so that the end of the limit pin 14 can enter the copper stranded wire in the middle of the fastening ring 6, and then the copper stranded wire and the fastening ring 6 can be fixed, so that when the copper stranded wire needs to be cut off, the situation that the copper stranded wire slides in the middle of the fastening ring 6 and affects the cutting process can be reduced, thereby improving the convenience of cutting the copper stranded wire, and when the first gear needs to be cut off, When the strip plate 9 is pulled, the first servo motor 11 connected to the middle of the fixed plate 10 can be operated, and then the first gear 12 can drive the first rack plate 9 to slide through the meshing action between the first gear 12 and the first rack plate 9, and then the steel cable 7 can be pulled, so that the fastening ring 6 can be tightened, and the situation of sliding caused by insufficient pressure during the process of cutting the copper stranded wire inside the fastening ring 6 can be reduced. After the copper stranded wire to be tested is placed in the middle of the fastening ring 6 and fixed, the second servo motor 17 can be operated, and then the second gear 18 can be used to drive multiple sets of second rack plates 19 to slide. When the plurality of cross bars 4 slide in the middle of the intercepting platform 1, the sliding rod 21 can be used to guide the plurality of cross bars 4, and the deviation of the plurality of cross bars 4 can be reduced when the cross bars 4 slide. Through the action of the guide port 22, the copper stranded wire can be guided when it is needed to be placed inside the fastening ring 6, thereby improving the convenience of placing the copper stranded wire.

[0043] For further information, see Figure 1-6 As shown, the cutting platform 1 has a plurality of combination pages 23 hinged in the middle thereof, a cover plate 24 hinged in the middle thereof, a placement slot 25 is provided in the middle thereof, and a support assembly is provided inside the placement slot 25 .

[0044] The supporting assembly includes a card pad 26, a connecting rope 27, an arc-shaped plug plate 28, and a spring column 29. The European spring column 29 is fixedly connected to the inside of the placement slot 25, and the end of the spring column 29 is fixedly connected to the card pad 26. The card pad 26 is slidably connected to the placement slot 25. The bottom of the card pad 26 is fixedly connected to the connecting rope 27, and the end of the connecting rope 27 is fixedly connected to the arc-shaped plug plate 28. The arc-shaped plug plate 28 is slidably connected to the placement slot 25.

[0045] During operation, when the copper stranded wire needs to be cut after being fixed, the cover plate 24 can be placed on the end of the cutting platform 1 through the action of the hinge 23, and then the copper stranded wire placed on the outside of the cutting platform 1 can be supported by the support component, so that when the copper stranded wire needs to be cut, the situation that the copper stranded wire scattered outside the cutting platform 1 affects the cutting work can be reduced. At the same time, the cut copper stranded wire can be fixed by the support component to reduce the situation that the copper stranded wire is scattered after cutting, and the cutting work is isolated by using the cover plate 24. When the cover plate 24 falls, the clamping pad 26 can come into contact with the copper stranded wire outside the cutting platform 1, and the clamping pad 26 can be squeezed upward. At this time, the spring column 29 will be compressed. When the clamping pad 26 moves upward, the multiple sets of arc-shaped plug-ins 28 can be pulled toward the middle through the connecting rope 27, and the arc-shaped plug-ins 28 can be placed at the bottom of the copper stranded wire. The cooperation between the clamping pad 26 and the arc-shaped plug-ins 28 can be used to squeeze and fix the copper stranded wire, and the scattering of the copper stranded wire can be reduced after the cutting is completed.

[0046] To sum up, the problem of needing to cut a certain unit length of stranded wire from the copper stranded wire soft connection for variable quantity detection is effectively solved. In the process of cutting the copper wire, the cut end of the copper wire needs to be wrapped and fixed. However, when copper wires of different lengths need to be cut, the fixing device at the end of the copper wire is difficult to move, and the middle part of the cut copper wire may come into contact with the outside world, which will cause certain errors in the electrical variable detection.

[0047] The electric variable detection method of the flat copper stranded wire flexible connection is mainly applicable to the above-mentioned electric variable detection device of the flat copper stranded wire flexible connection, and the method mainly includes the following steps:

[0048] S1: First, select the flat copper wire flexible connection material to be tested, and then fix it in the middle of the cutting platform 1;

[0049] S2: Cut off the end of the sheath in the flexible connector of the flat copper wire fixed in the middle of the cutting station 1, and then verify the insulation performance between the sheath and the conductor;

[0050] S3: Then clean the oxide layer or stains on the sample surface to ensure good conductivity at the contact point, and then conduct DC resistance testing;

[0051] S4: Use the four-wire method to connect the truncated sample to eliminate the interference of contact resistance and verify whether it meets the resistivity standard;

[0052] S5: Visually inspect or use a magnifying glass to observe surface oxidation, scratches, and stranding uniformity, and measure the cross-sectional area and strand pitch to verify whether they meet the design requirements.

[0053] Working principle:

[0054] When variable quantity detection is required, the copper stranded wire can be placed inside the clamping mechanism, and then the stretching mechanism can be used to make the sliding pad 3 slide in the middle of the slide groove 2, and then the two ends of the clamping mechanism can be stretched, thereby reducing the pulling of the copper stranded wire inside the clamping mechanism, so that the copper stranded wire is in a straight state, and then when performing electrical variable detection, the contact between the copper stranded wire and the intercepting platform 1 can be reduced, and the inaccurate variable quantity detection results caused by external factors can be reduced. When the copper stranded wire needs to be cut off, it can be placed inside the fastening ring 6, and then the first rack plate 9 can be pulled by the stretching component, thereby driving the steel cable 7 to slide inside the hook-shaped channel 8. When the steel cable 7 is pulled, the fastening ring 6 can be tightened. The first rack plate 9 is pulled to make the steel cable 7 slide in the middle of the hook-shaped channel 8, and the first trapezoidal plate 13 can be driven to slide by the steel cable 7, and the first trapezoidal plate 13 can push the second trapezoidal plate 16 upward to shrink the conical spring 15, and then the limit pin 14 in the middle of the second trapezoidal plate 16 can rise from the middle of the cross bar 4, so that the end of the limit pin 14 can enter the copper stranded wire in the middle of the fastening ring 6, and then the copper stranded wire and the fastening ring 6 can be fixed, so that When the copper stranded wire needs to be cut off, the situation in which the copper stranded wire slides in the middle of the fastening ring 6 and affects the cutting process can be reduced, thereby improving the convenience of cutting the copper stranded wire. When the first rack plate 9 needs to be pulled, the first servo motor 11 connected to the middle of the fixing plate 10 can be operated, and then the first gear 12 can drive the first rack plate 9 to slide through the meshing action between the first gear 12 and the first rack plate 9, and then the steel cable 7 can be pulled, so that the fastening ring 6 can be tightened, and the situation in which the copper stranded wire inside the fastening ring 6 is cut off due to insufficient pressure and causes slippage can be reduced. After the copper stranded wire to be tested is placed in the middle of the fastening ring 6 and fixed, the second servo motor 17 can be operated, thereby The second gear 18 can be used to drive multiple groups of second rack plates 19 to slide, thereby separating or converging multiple groups of cross bars 4, and then when the copper stranded wire needs to be tested for variable power, the copper stranded wire inside the fastening ring 6 can be straightened, and it can adapt to the detection of copper stranded wires of different lengths, so that the detection result is more accurate. When the multiple groups of cross bars 4 slide in the middle of the cutting platform 1, the sliding rod 21 can be used to guide the multiple groups of cross bars 4, thereby reducing the deviation of the multiple groups of cross bars 4 when the cross bars 4 slide. Through the action of the guide port 22, the copper stranded wire can be guided when it is needed to be placed inside the fastening ring 6, thereby improving the convenience of placing the copper stranded wire. When the copper stranded wire needs to be cut after being fixed,The cover plate 24 can be placed at the end of the cutting platform 1 by the action of the hinge 23, and then the copper stranded wire placed on the outside of the cutting platform 1 can be supported by the support assembly, so that when the copper stranded wire needs to be cut, the situation that the copper stranded wire scattered outside the cutting platform 1 affects the cutting work can be reduced. At the same time, the copper stranded wire after cutting can be fixed by the support assembly to reduce the situation that the copper stranded wire is scattered after cutting. When the cover plate 24 is used to isolate the cutting work, the clamping pad 26 can contact the copper stranded wire outside the cutting platform 1 when the cover plate 24 falls, and the clamping pad 26 can be squeezed upward. At this time, the spring column 29 will be compressed. When the clamping pad 26 moves upward, the multiple groups of arc-shaped plug-ins 28 can be pulled toward the middle by the connecting rope 27, and the arc-shaped plug-ins 28 can be placed at the bottom of the copper stranded wire. The cooperation between the clamping pad 26 and the arc-shaped plug-ins 28 can be used to squeeze and fix the copper stranded wire, and the situation that the copper stranded wire is scattered can be reduced after the cutting is completed.
