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

[0034] Example 1 provides a high-voltage wire harness electrical inspection and testing tool:

[0035] A stand 11 is provided on the upper end of the support plate 10 , and a testing station is provided on the front side of the stand 11 .

[0036] The lining 20 is slidably connected to the support plate 10 , and the sliding matching structure of the lining 20 and the support plate 10 is wedge-shaped, so that the lining 20 will not be separated from the support plate 10 .

[0037] A receiving groove 21 is provided on the base 20, and the receiving groove 21 is used to place the high-voltage wire harness. The receiving groove 21 has a terminal groove 211 and a wire harness groove 212 connected to each other. The terminal groove 211 is adapted to the terminal of the high-voltage wire harness, and the wire harness groove 212 is adapted to the wire harness of the high-voltage wire harness, so that the high-voltage wire harness plays a positioning role when placed, ensuring that the positive and negative ends of the high-voltage wire harness terminals are in specific positions.

[0038] The tail end of the harness groove 212 is connected to a bearing block 22 , and the terminal at the other end of the high-voltage harness is supported by the bearing block 22 .

[0039] The test assembly 30 includes a lifting plate 31 , on which an insulation resistance tester 32 is mounted. The lifting plate 31 is connected to an adjustment cylinder 34 via a movable portion 33 . A straight cylinder 35 is fixedly attached to the lifting plate 31 . One set of wires from the insulation resistance tester 32 passes through the lower end of the straight cylinder 35 and is connected to a first test lead 351 . Another set of wires passes through the lower end of the adjustment cylinder 34 and is connected to a second test lead 341 .

[0040] During the test, the first test lead 351 contacts the shielding layer of the high-voltage wiring harness, and the second test lead 341 contacts the positive or negative terminal of the high-voltage wiring harness terminal. After applying a DC voltage (500V or 1000V), the insulation resistance value can be tested without entanglement.

[0041] The insulation resistance tester 32 has a screen that displays the insulation resistance value and is connected to a player, so as to determine whether the insulation resistance value of the tested high-voltage wire harness is qualified.

[0042] The pulling assembly 40 connects the lifting plate 31 and the lining table 20. The pulling assembly is used to drive the lifting plate 31 to move vertically to the test station, and to pull the lining table 20 to move horizontally to the test station. When taking and placing the high-voltage wire harness, the lining table 20 is away from the test station, which effectively increases the operating space for taking and placing the high-voltage wire harness, and is easy to operate. When conducting the test, the lining table 20 is pulled by the pulling assembly 40 and moves horizontally to the test station, that is, away from the operator, making it difficult for the operator to touch it, thereby improving the safety of the test.

[0043] Example 2 provides a high-voltage wire harness electrical inspection and testing tool:

[0044] The pulling and moving assembly 40 includes an electric cylinder body 41 installed on the bracket, a movable frame 42 pivotally connected to the support plate 10, and a pulley 43 arranged on the lining platform 20. The movable rod of the electric cylinder body 41 is connected to the lifting plate 31. A shift groove 44 is provided at one end of the movable frame 42 for the pulley 43 to slide and engage. The other end of the movable frame 42 is hinged with a ring body 45. The lifting plate 31 is connected to a straight rod 46. The bottom end of the straight rod 46 is connected to a pressure rod 47 passing through the ring body 45.

[0045] The electric cylinder body 41 drives the lifting plate 31 to descend vertically, and the pressure rod 47 presses the ring body 45 downward, driving the movable frame 42 to pivot and then pull the pulley 43 through the shifting groove 44 to move the lining platform 20 laterally. Thus, by driving the lifting plate 31 to descend or ascend vertically by the electric cylinder body 41, the positions of the lining platform 20 and the lifting plate 31 can be controlled synchronously. When the lifting plate 31 is vertically lowered to the test station, the second test lead 341 is driven to move downward to contact the positive terminal or negative terminal of the high-voltage wiring harness.

[0046] A plurality of guide rods 12 are provided on the support plate 10 , and the plurality of guide rods 12 are passed through the lifting plate 31 to guide the vertical movement of the lifting plate 31 .

[0047] Example 3 provides a high-voltage wire harness electrical inspection and testing tool:

[0048] A cover body 23 is hinged on the base 20, and the cover body 23 can be rotated to the upper side of the terminal slot 211 to crimp the high-voltage wiring harness terminal. The cover body 23 has two groups of detection holes, and the two groups of detection holes correspond to the positive terminal and the negative terminal of the high-voltage wiring harness terminal respectively. The cover body 23 is made of insulating material and plays an isolation role when crimped on the high-voltage wiring harness terminal, further improving the safety of the test, and the detection holes correspond to the positive terminal and the negative terminal of the high-voltage wiring harness terminal respectively, so that the second test lead 341 can enter the detection hole to perform insulation resistance value testing.

[0049] The movable part 33 includes a partition 331 arranged on the lower side of the lifting plate 31 and a movable sleeve 332 slidingly connected to the lifting plate 31. The partition 331 has an arc groove 333. A rocker arm 334 and a motor body 335 driving the rocker arm 334 to rotate are provided on the partition 331. A push rod 336 is provided on the rocker arm 334. The push rod 336 is slidingly engaged with the arc groove 333. The adjusting cylinder 34 is passed through the movable sleeve 332 and is rotationally connected to the push rod 336.

[0050] Driven by the pulling assembly 40, when the lifting plate 31 and the lining platform 20 move to the test station, the lifting plate 31 drives the second test lead 341 to move downward synchronously. At this time, the first test lead 351 contacts the shielding layer of the high-voltage wiring harness, and the push rod 336 is located at one end of the arc groove 333, so that the second test lead 341 synchronously enters a group of detection holes, and automatically performs a contact test on one of the positive and negative terminals of the high-voltage wiring harness terminal. After completing a test, the motor body 335 drives the rocker arm 334 to rotate and drives the push rod 336 to move to one end of the arc groove 333, so that the second test lead 341 moves from one group of detection holes to another group of detection holes, thereby performing a contact test on the other of the positive and negative terminals of the high-voltage wiring harness terminal, realizing automated testing, and there is no need for manual hand-held movement of the second test lead 341, and the testing efficiency is high.
