[0002] Copper busbar, also known as copper busbar or copper busbar, is made of copper and is a long conductor with a rectangular or chamfered (rounded) rectangular cross-section (rounded copper busbars are generally used nowadays to avoid tip discharge). It plays the role of transmitting current and connecting electrical equipment in the circuit.

[0003] Currently, in order to prevent copper busbars from leaking electricity during use, the surface of the copper busbar is usually covered with an insulating layer. During the production process of the copper busbar covered with the insulating layer, the insulation effect of the insulating layer needs to be tested to prevent the copper busbar from leaking electricity. However, when testing copper busbar products, the existing test tooling can only test one copper busbar product at a time, which has low work efficiency. In addition, the test tooling usually only has two conductive probes. When testing copper busbar products with multiple connection ends, it is difficult to ensure the accuracy of the test results.

[0024] Example:

[0025] See also Figure 1-4 A multi-station copper busbar testing tool comprises a base plate 1 and a pressing plate 2. The pressing plate 2 is arranged on the upper side of the base plate 1. The top of the base plate 1 is fixedly connected to multiple test benches 3. The tops of the multiple test benches 3 are all opened with copper busbar grooves 4. The bottom end of the pressing plate 2 is fixedly connected to multiple clamping blocks 5, and the multiple clamping blocks 5 respectively correspond to the multiple copper busbar grooves 4. A group of positive probes 6 are respectively fixedly connected in the multiple copper busbar grooves 4. A group of ground wire connectors 7 are fixedly connected to the multiple test benches 3, and the multiple groups of ground wire connectors 7 respectively correspond to the multiple copper busbar grooves 4. Each group of positive probes 6 is provided with multiple, and each group of ground wire connectors 7 is provided with multiple.

[0026] In this embodiment, the copper busbar is placed in a plurality of copper busbar slots 4, the connection ends of the copper busbar are in contact with a plurality of sets of positive probes 6, and the plurality of copper busbar slots 4 are filled with conductive foam so that the conductive foam wraps the insulating layer on the surface of the copper busbar. The pressing plate 2 presses down the plurality of pressing blocks 5 through a press machine, and the plurality of pressing blocks 5 make the conductive foam in the plurality of copper busbar slots 4 in close contact with the plurality of ground connectors 7. Then, the plurality of sets of positive probes 6 are energized by an external power supply so that the plurality of copper busbars are simultaneously conducted by current. When leakage occurs in the insulating layer of the copper busbar, the plurality of sets of ground connectors 7 connected to the ground wires detect the leakage state through the conductive foam, thereby obtaining the test result of the insulation layer of the copper busbar. The specific number of each set of positive probes 6 is set according to the number of the connection ends of the copper busbar so that the copper busbar is conducted between the plurality of connection ends. The number of each set of ground connectors 7 is set according to the shape of the copper busbar so that each part of the copper busbar can be accurately tested.

[0027] Specifically, a fixing box 8 is fixedly connected to the bottom plate 1 , and a plurality of power connectors 9 are fixedly connected in the fixing box 8 . The plurality of power connectors 9 are electrically connected to the plurality of positive electrode probes 6 and the plurality of ground connectors 7 .

[0028] In this embodiment, the multiple power connectors 9 in the fixing box 8 are connected to the multiple groups of positive probes 6 and the multiple groups of ground connectors 7 through lines, so that the connection lines of the multiple groups of positive probes 6 and the multiple groups of ground connectors 7 are centrally processed to avoid line entanglement.

[0029] Specifically, the top end of the base plate 1 is fixedly connected with a positioning block group 10 , the bottom end of the pressing plate 2 is fixedly connected with a positioning column group 11 , and the positioning column group 11 matches the positioning block group 10 .

[0030] In this embodiment, when the pressing plate 2 is pressed down to move the multiple pressing blocks 5 into the copper bar groove 4, the positioning column group 11 enters the positioning block group 10 to position the pressing plate 2 so that the multiple pressing blocks 5 accurately enter the multiple copper bar grooves 4.

[0031] Working principle: When testing multiple copper busbars with multiple connection ends, the multiple copper busbars are placed in multiple copper busbar slots 4 respectively, and the multiple connection ends of each copper busbar are in contact with a group of multiple positive probes 6 respectively. The multiple copper busbar slots 4 are filled with conductive foam, so that the conductive foam wraps the insulating layer on the surface of the copper busbar. The pressing plate 2 presses down the multiple pressing blocks 5 through a press machine. The multiple pressing blocks 5 make the conductive foam in the multiple copper busbar slots 4 in close contact with the multiple groups of ground wire connectors 7. Then, the multiple groups of positive probes 6 are energized by an external power supply, so that the multiple copper busbars are simultaneously conducted by current. When the copper busbar leaks at the insulation layer, the multiple groups of ground wire connectors 7 connected to the ground wire detect the leakage state through the conductive foam, thereby obtaining the test result of the copper busbar insulation layer.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this.
