[0036] In all the examples shown and discussed herein, any specific value should be construed as merely exemplary and not as a limitation. Therefore, other examples of the exemplary embodiments may have different values.

[0037] According to a wire conductor resistance testing device of the present disclosure, it is used to detect the resistance value of the conductor to be tested of the wire, as Figures 1 to 4 shown, including,

[0038] Base 100;

[0039] Lifting component 200, the lifting component 200 is arranged on the base 100, and the lifting component 200 includes a lifting table 201 that is movable relative to the base 100;

[0040] Wire fixing component 300, fixed on the lifting table 201, includes two clamping members 301 arranged at intervals, and the two clamping members 301 respectively clamp the conductor to be tested in the energized state, and the area where the conductor to be tested is located between the two clamping members 301 forms a to-be-tested area;

[0041] Detection component 400, the detection component 400 is arranged on the base 100 and has two input ends 401 of the detection device that are independent of each other, and the two input ends 401 of the detection device are respectively in conductive contact with different positions of the conductor to be tested located in the to-be-tested area to detect the resistance value of the conductor to be tested located between the two input ends 401 of the detection device.

[0042] The wire fixing assembly 300 is arranged on the lifting platform 201, and the height of the conductor to be measured relative to the base 100 can be adjusted in the state where the conductor to be measured is arranged on the clamping member 301, so that the height of the conductor to be measured matches the height of the input end 401 of the detection device in the detection assembly 400, so that the abutting surfaces of the two detection device input ends 401 that can abut against the conductor can conduct electricity against the conductor to be measured to the greatest extent at a suitable position.

[0043] In an embodiment of a wire conductor resistance testing device according to the present disclosure, as Figure 4 shown, the lifting assembly 200 further includes a bottom plate 202 and a top plate 203 arranged in parallel with the lifting platform 201, two guide columns 204 respectively connected to the bottom plate 202 and the top plate 203 at both ends, and a lead screw arranged between the two guide columns 204. The guide columns 204 are parallel to each other and perpendicular to the bottom plate 202 and the top plate 203. A linear bearing 206 passing through the guide column 204 is fixedly arranged on the lifting platform 201, and a nut bracket 207 screwed to the lead screw. One end of the lead screw passes through the top plate 203 and is connected to the handwheel 208. Rotating the handwheel 208 drives the lead screw to rotate, and the lead screw drives the nut bracket 207 and the lifting platform 201 to move along the guide column 204.

[0044] Adjusting the nut bracket 207 through the lead screw 205 can drive the lifting platform 201 to move up and down relative to the base 100, so as to drive the conductor to be measured clamped by the clamping member 301 to move up and down, so that the conductor to be measured is in a suitable position, so that the two detection device input ends 401 abut against the conductor to be measured to the greatest extent.

[0045] In an embodiment of a wire conductor resistance testing device according to the present disclosure, as Figure 1 shown, the wire fixing assembly 300 includes a first guide rail 302 connecting the lifting platform 201, and any one of the two clamping members 301 is slidably arranged on the first guide rail 302 independently of the other. The distance between the two clamping members 301 can be arbitrarily changed on the first guide rail 302 to clamp conductors to be measured with different lengths.

[0046] Specifically, as Figure 1 and Figure 4 shown, the clamping member 301 includes a clamping seat 303 slidably arranged on the first guide rail 302, and two clamping jaws 304 arranged on the clamping seat 303. The distance between the two clamping jaws 304 is adjustable and can clamp the conductor to be measured.

[0047] During specific testing, at least one of the two jaws 304 on the same clamping member 301 is made of a conductive material, so as to set the conductor under test in the circuit of the testing device to pass a constant current through the conductor under test; the input end 401 of the detection device clamps the area under test and detects the voltage value at both ends of the clamped area, and the resistance detection device calculates the resistance value based on the voltage value and the current value and displays it.

[0048] Specifically, the jaws can be copper jaws.

[0049] More specifically, as Figure 4 shown, the clamping member 301 further includes a first insulating pad member 305 disposed between the jaw 304 and the clamping seat 303 to keep the jaw 304 and the clamping seat 303 insulated from each other. So that the area outside the jaw 304 is kept insulated, protecting the personal safety of the operator and avoiding harm to the operator.

[0050] The material of the first insulating pad member 305 can be a ceramic material.

[0051] Specifically, as Figure 1 shown, the wire fixing assembly 300 further includes at least two auxiliary supports 306 slidably disposed on the first guide rail 302. The two auxiliary supports 306 are located between the two clamping members 301, and a support rod 307 for supporting the conductor under test is disposed on the auxiliary support 306. A force is provided to the conductor under test toward the side of the input end 401 of the detection device through the support rod 307 to prevent the conductor under test from shifting when the input end 401 of the detection device abuts against the conductor under test.

[0052] More specifically, a second insulating pad member is disposed on the support rod 307, and the second insulating pad member contacts the conductor under test. This avoids the support rod 307 and the wire conductor resistance testing device from being charged through the conductor under test, which may cause harm to the operator.

[0053] During specific implementation, it can also be that at least the support rod 307 among the auxiliary support 306 and the support rod 307 is made of an insulating material to form the second insulating pad member. The insulating material can be a ceramic material.

[0054] In an embodiment of a wire conductor resistance testing device according to the present disclosure, as Figure 2 shown, the detection assembly 400 further includes a second guide rail 402, the second guide rail 402 is parallel to the conductor under test after clamping, and either one of the two input ends 401 of the detection device is slidably disposed on the second guide rail 402 independently of the other. The two input ends 401 of the detection device can be adjusted as needed so that the two input ends 401 of the detection device clamp different lengths in the area under test to detect the resistance value of a specified length.

[0055] Specifically, as Figure 2 shown, the detection component 400 further includes two third guide rails 403 disposed on the base 100. The third guide rails 403 are perpendicular to the conductor to be measured after being clamped. The second guide rail 402 is disposed on the third guide rails 403 and can move along the third guide rails 403. By moving the second guide rail 402 on the third guide rails 403, the distance between the input end 401 of the detection device and the conductor to be measured can be adjusted, so that the second guide rail 402 can be slid according to requirements (for example, the wire diameter of the conductor to be measured).

[0056] More specifically, as Figure 2 shown, the input end 401 of the detection device includes a detection base 404 and a detection probe 405. The detection base 404 is slidably disposed on the second guide rail 402, and a positioning mechanism 406 is disposed on the detection base 404 to fix the relative position of the detection base 404 and the second guide rail 402.

[0057] The input end 401 of the detection device conducts electricity through the detection probe 405 to abut against the outside of the conductor to be measured. With the voltage value between the two detection probes 405, the resistance detection device calculates and displays the resistance value through the voltage value and the current value. The detection base 404 is set at a predetermined position through the positioning mechanism 406.

[0058] More specifically, positioning points are provided on the surface of the third guide rail 403 facing the positioning mechanism 406. When the detection base 404 moves to a set position, it is clamped with the positioning points through the positioning mechanism 406, thereby fixing the input end 401 of the detection device.

[0059] During specific implementation, multiple positioning points are provided on the third guide rail 403, and the multiple positioning points are equidistantly spaced. The length of the conductor to be measured between the two detection probes 405 can be calculated through the positioning points, and the input end 401 of the detection device is fixed on the second guide rail 402 through the clamping between the positioning points and the positioning mechanism 406.

[0060] Although some specific embodiments of the present invention have been described in detail through examples, those skilled in the art should understand that the above examples are only for illustration and not for limiting the scope of the present invention. Those skilled in the art should understand that the above embodiments can be modified without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
