[0027] Reference Figure 1 and Figure 2 , Figure 1 and Figure 2 A new energy laboratory power wiring harness terminal connection device provided in an embodiment of the present application is shown, including an insulating shell 100, on which at least one wiring terminal 200 is penetrated, and a mounting groove 221 is provided on the insulating shell 100, one end of the wiring terminal 200 is movably connected to the mounting groove 221, and the other end of the wiring terminal 200 extends out of the mounting groove 221, and the groove wall of the mounting groove 221 and the outer side wall of the wiring terminal 200 enclose a movable cavity for the wiring terminal 200 to swing.

[0028] In the present invention, by adjusting the height and spacing of the power harness terminal 200 in the active cavity, the terminal 200 can be connected to the three-phase motor harness with different output requirements and the corresponding terminal 200 quickly and safely. There is no need to adjust the unmatched terminals due to size mismatch when the power harness terminals are connected to each other, and there is no need to waste high-temperature insulating tape to adjust the unmatched terminals, which in turn leads to high safety risks and inconvenience in replacement.

[0029] Reference Figure 2 In some embodiments, the terminal block 200 includes a first sub-terminal 210 and a second sub-terminal 220. The insulating housing 100 is provided with a connecting groove 211 that matches the size of the first sub-terminal 210. One end of the first sub-terminal 210 is connected to the connecting groove 211, and the other end of the first sub-terminal 210 extends out of the connecting groove 211. An external thread is provided on the outer end surface of the first sub-terminal 210, and an internal thread matching the external thread is provided on the inner wall of the connecting groove 211. The end of the first sub-terminal 210 facing the insulating housing 100 is threadedly connected to the connecting groove 211.

The end of the second sub-terminal 220 facing the insulating housing 100 is threadedly connected to the mounting groove 221.

[0030] During the process of connecting the first sub-terminal 210 to the insulating housing 100, the external thread on the outer surface of the first sub-terminal 210 is directly threaded into the internal thread of the connecting groove 211, so that the first sub-terminal 210 is threaded into the connecting groove 211 on the insulating housing 100 that matches the size of the first sub-terminal 210; during the process of connecting the second sub-terminal 220 to the insulating housing 100, the threaded end of the second sub-terminal 220 is first threaded into the installation groove 221 of the insulating housing 100, and then the position between the second sub-terminal 220 and the first sub-terminal 210 is moved until it corresponds to the preset motor three-phase line output terminal, completing the connection between the second sub-terminal 220 and the insulating housing 100.

[0031] It is worth mentioning that the active cavities corresponding to the connection terminals 200 at both ends of the insulating housing 100 may be connected or disconnected. In this embodiment, they are connected.

[0032] Reference Figure 1 and Figure 2 In this embodiment, the connecting device further includes:

[0033] The insulating housing 100 is further provided with a test piece 300, which is used to detect the back electromotive force corresponding to the connection terminal 200. The test piece 300 also includes:

[0034] A test bolt 310 is passed through the insulating housing 100. The screwed-in end of the test bolt 310 contacts the wiring terminal 200. The fixed end of the test bolt 310 is tightly abutted against the insulating housing 100. The insulating housing 100 is provided with a test hole that matches the test bolt 310. The inner wall of the test hole is provided with a test thread that matches the test bolt 310. The thread of the test bolt 310 is connected to the inner wall of the test hole. The test bolt 310 is also passed through a test gasket 312, which is tightly abutted between the insulating housing 100 and the fixed end of the test bolt 310.

[0035] The insulating housing 100 is further provided with a protective plate 400 , and the protective plate 400 is provided with a protective shell 410 that matches the size of the insulating housing 100 . The insulating housing 100 is provided with a snap fastener, and the protective shell 410 and the protective plate 400 enclose a protective cavity for protecting the terminal 200 .

[0036] In this embodiment, by rotating the test bolt 310 and connecting the terminal 200 to each other, the staff can quickly connect the oscilloscope voltage differential probe, thereby quickly obtaining the wiring for motor back electromotive force and waveform measurement, thereby improving measurement efficiency.

[0037] A method for detecting a power harness terminal connection device in a new energy laboratory comprises threading a terminal block onto an insulating housing;

[0038] adjusting a position of the second sub-terminal based on a preset power harness position;

[0039] After connecting the wiring terminals to the corresponding power harness, snap the protective shell onto the protective plate.

[0040] In one embodiment, when it is necessary to measure the motor back EMF or waveform of the terminal, the detection end of the preset detection cable is connected between the test pad and the test bolt, and the test bolt is rotated until the test bolt contacts the terminal;

[0041] Otherwise, turn the test bolt until there is clearance between the test bolt and the terminal block.
