[0002] The automatic motor wiring harness testing device is mainly used to automate the testing of motor wiring harnesses during the production of range hoods. This ensures the correctness, stability, and safety of the wiring harness connections. The testing process involves connecting a simulated power supply and testing whether the motor wiring harness can transmit current normally. Essentially, it verifies whether the wiring harness can stably and safely transmit power in actual use. This process helps ensure that the electrical connection between the motor and the wiring harness is problem-free in the final product, preventing motor failure or safety issues due to wiring harness malfunctions.

[0003] A patent with publication number CN219694745U discloses an automatic detection device for a range hood motor wiring harness. The device includes a body, which comprises a base and a turntable. The turntable is fixedly installed on the upper outer wall of the base. A twisting wheel is installed at the center of the turntable, and a groove is formed around its edge.

Several sets of balls are installed inside the ball groove and the groove on the outer wall of the twisting wheel. A motor is installed on one side of the twisting wheel, and the output end of the motor is fixedly connected to the center of the twisting wheel. This device, by incorporating the twisting wheel and a pull ring, allows the strength of the motor wiring harness to be tested via the pull ring after it has been tightened, thus performing twisting and testing simultaneously and improving efficiency.

[0004] However, its device can only test the tensile strength of the wire harness and does not have a structure to test the power supply of the wire harness, so it cannot guarantee that the generated wire harness can be used normally after it is installed with the motor. Utility Model Content

[0005] The purpose of this utility model is to provide an automatic detection device for the wiring harness of a range hood motor, so as to solve the problem that the existing device can only test the tensile strength of the wiring harness, but does not have a structure to test the power supply of the wiring harness, and cannot guarantee that the generated wiring harness can be used normally after installation with the motor.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic detection device for a range hood motor wiring harness, comprising a power detection box, a connector fixedly installed on one side of the upper end of the power detection box, a charging hole for convenient testing of whether the motor wiring harness is powered on on one side of the connector, a protective structure provided at the upper end of the power detection box, the protective structure comprising a fixing plate fixedly installed at the upper end of the power detection box, a cable routing groove opened at the upper end of the fixing plate, a fixing seat fixedly installed at the front side of the upper end of the power detection box, a cover plate rotatably installed inside the fixing seat, the cover plate being located at the upper end of the connector and the fixing plate.

[0007] Preferably, a locking structure is provided between the cover plate and the power detection box. The locking structure includes a horizontal plate fixedly installed on the rear side of the lower end of the cover plate and a locking block fixedly installed on the rear side of the upper end of the power detection box. A movable rod is movably installed inside the locking block, and a spring is provided on the outer wall of the movable rod. A locking hole is opened on the side wall of the cover plate located on one side of the movable rod.

[0008] Preferably, a sponge pad is fixedly provided on the inner wall of the cable tray.

[0009] The foam pad can protect the wire harness inside the cable tray.

[0011] The tilting plate supports the flipped cover.

[0012] Preferably, a pull plate is fixedly provided on one side of the movable rod.

[0013] The pull plate is used to pull the movable rod, causing it to be compressed and paralyzed, allowing one end of the movable rod to be removed from the locking hole.

[0014] Preferably, a rotating shaft is fixedly provided on the inner wall of the fixed base, and the cover plate is rotatably installed on the outer wall of the rotating shaft.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1) By setting up a protective structure, wires can be separated during power-on testing of the wiring harness, ensuring the neatness of the power cords. At the same time, the flip-up cover can protect the wiring harness connection end and the test head on the upper side of the power test box from damage caused by foreign objects.

[0017] 2) By setting a locking structure, after the cover plate is flipped over, the elastic movable rod can be used to secure the cover plate after it is flipped over, thus preventing the cover plate from becoming loose.

[0018] 3) By setting an inclined plate, the open cover will not obstruct the operator's view when observing or operating the front of the power supply test box, making it convenient for the operator to adjust the power supply test box. Attached Figure Description
