[0002] In electrical systems, copper busbars are usually used to transmit current, and their resistance value is crucial to the performance and safety of the system. The copper busbar resistance test device is a device used to test the resistance value of the copper busbar, which can help ensure that the copper busbar has good conductivity.

[0003] The test method for copper bar resistance is generally to connect the positive and negative electrodes to the two ends of the copper bar respectively to ensure that the connection is firm, and then use the test fixture to connect the voltmeter and resistance meter to the two test terminals of the copper bar. Then turn on the current source to pass the current through the copper bar, and calculate the resistance value of the copper bar through the resistance meter, and finally evaluate it.

[0004] However, after testing a copper busbar, most test devices need to remove the test terminal, take out the tested copper busbar and replace it, and then install the test terminal again. As a result, each replacement and installation of the test terminal takes a lot of time during the test process, which makes it difficult to adapt to the testing of multiple batches of copper busbars. Therefore, it is necessary to provide a copper busbar resistance testing device to solve the above problem.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] like Figure 1-Figure 2 As shown, the present application provides a copper bar resistance testing device, including a base plate 1, a support plate 11 is fixedly installed on the upper end of the base plate 1, an adjusting member is arranged on the support plate 11, and the adjusting member has a slide rail 12 fixedly installed on one side of the support plate 11, a slider 13 is fixedly installed on the slide rail 12, and a cylinder 14 is fixedly installed on the upper end of the support plate 11, and the output shaft of the cylinder 14 is fixedly installed on the upper end of the slider 13, so that the slider 13 can be driven to slide up and down on the slide rail 12 by the cylinder 14.

[0034] Two groups of test terminals 2 are fixedly installed at the lower end of the slider 13. In the present application, the two groups of test terminals 2 are electrically connected to a voltmeter and an ohmmeter, respectively, and the resistance value of the copper busbar is tested by the voltmeter and the ohmmeter.

[0035] In order to adapt to the test of multiple batches of copper busbars, a fixing frame 15 is fixedly installed on the upper end of the bottom plate 1, and a turntable 3 is arranged on the upper end of the fixing frame 15. A plurality of groups of clamping members 4 are installed on the turntable 3. The clamping members 4 are used to clamp and fix the copper busbars to be tested. The plurality of groups of clamping members 4 are arranged in a circle with the axis of the turntable 3 as the center.

[0036] The clamping member 4 has a fixed plate 41 fixed on the rotating disk 3, a connecting rod 42 is provided through the fixed plate 41, a movable plate 43 is fixedly installed at one end of the connecting rod 42 away from the fixed plate 41, and the movable plate 43 is made of insulating material, and a spring 44 is fixedly installed between the fixed plate 41 and the movable plate 43, and the spring 44 is sleeved on the connecting rod 42;

[0037] In addition, a clamping plate 45 is provided on the side of the movable plate 43 away from the fixed plate 41. The clamping plate 45 is made of rubber and is fixedly installed on the turntable 3. Therefore, when installing the copper bar, one end of the copper bar is first attached to the movable plate 43, and then the movable plate 43 is pushed toward the fixed plate 41. At this time, the connecting rod 42 slides and the spring 44 contracts until the copper bar is completely clamped between the movable plate 43 and the clamping plate 45. The clamping force of the copper bar can be buffered by the rubber clamping plate 45 to prevent damage to the side surface of the copper bar, thereby completing the installation of the copper bar.

[0039] A plurality of rollers 32 are fixedly mounted on the upper end of the fixing frame 15 . The plurality of rollers 32 are arranged in a circle with the rotating shaft 31 as the center and attached to the lower end of the turntable 3 . Therefore, the rotation efficiency of the turntable 3 is improved by the rollers 32 .

[0040] In summary: when testing the resistance of the copper busbar, multiple groups of clamps 4 are filled with the copper busbars to be tested, and then the turntable 3 is started to adjust the copper busbars of one group to the lower end of the test terminal 2, and then the cylinder 14 is started to drive the test terminal 2 downward until the test terminal 2 is attached to the surface of the copper busbar, and then the voltmeter and the resistance meter are used for testing. After the test is completed, the cylinder 14 drives the test terminal 2 upward, and the above operation is repeated, and the turntable 3 is continued to be rotated to adjust the clamps 4 of the next group to the lower end of the slider 13, so as to continue to test the copper busbars of the next group, thereby saving the time of replacing and installing the test terminal 2 and realizing the testing of multiple batches of copper busbars.
