A wiring harness is a component that connects circuits by crimping copper contact terminals with wires and cables, then molding an insulator or adding an outer metal shell, and bundling the wires together.

[0003] To ensure the proper functioning of automobiles, every automotive wiring harness produced must be tested. Testing typically checks for continuity and whether the harness fulfills its intended function. However, automobiles have diverse functions, and some require wiring harnesses to connect to motors and switches. How to test these specialized wiring harnesses is a current area of ​​research. Utility Model Content

The motor testing mechanism includes a fixed platform, a transmission rod, two small cylinders, and a rack. The fixed platform has a fixed groove, and two bearing seats are mounted on the testing platform. The transmission rod is inserted into and rotatably connected to the two bearing seats. A testing wheel is fixed to one end of the transmission rod, located on one side of the fixed platform. When the motor is engaged in the fixed groove, its output shaft is positioned above the testing wheel and in contact with its upper surface. The output shafts of the two small cylinders are arranged opposite each other, the rack is located between the two small cylinders, and the output shafts of the two small cylinders abut against the two ends of the rack respectively. A gear is fixed on the transmission rod, the gear is located above the rack and meshes with the rack. The detection platform is equipped with two proximity switches, namely a forward rotation detection proximity switch and a reverse rotation detection proximity switch, which are located on both sides of the front end of the rack. The switch detection mechanism includes a fixed platform 2, which has a fixed groove 2 for placing the circuit boards containing the two switches. Two detection cylinders are fixed on the fixed platform 2, and the two detection cylinders are respectively located at one end of the two switches.

[0006] Preferably, a slider is welded to the lower end face of the rack, a slide rail is fixed on the detection table, and the slide groove at the lower end of the slider is sleeved on the slide rail, so that the slider and the slide rail slide together.

[0007] Preferably, the switch detection mechanism further includes a small cylinder two, which is fixed on a fixed platform two.

[0014] The following description is merely a preferred embodiment of this utility model, and the scope of protection is not limited to this embodiment. All technical solutions falling within the scope of this utility model's concept should be protected. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom" and "top," "inner" and "outer" refer to directions toward or away from the geometric center of a specific component.

[0015] like Figure 1 and Figure 2 As shown, a testing device for a right-hand latch motor wiring harness assembly is mainly used for testing automotive wiring harnesses, especially for dedicated wiring harnesses connecting motors and switches. This testing device can efficiently and accurately test the continuity of the wiring harness and whether the motor and switch are functioning properly.

[0016] The overall structure of the testing device includes a testing platform 1, on which a terminal fixing mechanism, a motor testing mechanism, and a switch testing mechanism are installed. One end of the wire harness under test is provided with a terminal block, and the other end is connected to a motor and two switches. The two switches are mounted on the same circuit board and are both push-button switches.

[0017] The circuit system for detection and control functions is integrated and installed in the detection box below the detection platform 1. When the circuit needs to be repaired or replaced, it can be maintained simply by lifting the detection platform 1. A start button and an alarm are also provided on the platform of the detection platform 1. The operator can start the detection process by pressing the start button.

[0018] If any abnormality is detected in the motor or switch function at any stage, the alarm on the testing station 1 will sound immediately to alert the operator that the product is faulty. The alarm will only automatically deactivate and the system will reset to prepare for the next test after the operator removes the faulty product from the testing station and places it in the designated waste bin next to it.

[0019] The terminal fixing mechanism is located on one side of the testing table 1 and is used to fix the wiring terminals of the wire harness. The mechanism includes a fixing platform 3 17, which has a fixing slot 3. The wiring terminals can be inserted into the fixing slot 3 to achieve initial fixing.

[0020] To ensure that the terminal block does not loosen during testing, an electromagnetic lock 18 is also provided on the front side of the mounting plate 3 17, and a locking tongue 19 is connected to the output shaft of the electromagnetic lock 18. When the terminal block is inserted into the mounting plate 3, the electromagnetic lock 18 pushes the locking tongue 19 to move, so that the locking tongue 19 abuts against one side of the terminal block, thereby fixing the terminal block in the mounting plate 3 and preventing the terminal block from moving out.

[0021] The motor testing mechanism is located in the center of the testing platform 1 and is used to test the forward and reverse rotation function of the motor. This mechanism includes a fixed platform 2, a transmission rod 3, two small cylinders 4, and a rack 5. The fixed platform 2 has a fixing groove for engaging the motor, positioning its output shaft in a predetermined position. The testing platform 1 has two bearing seats 6, and the transmission rod 3 is inserted into and rotatably connected to the bearing seats 6. A testing wheel 7 is fixedly mounted on one end of the transmission rod 3. When the motor is engaged in the fixing groove, its output shaft is positioned above the testing wheel 7 and in contact with its upper surface. Thus, when the motor rotates, the output shaft drives the testing wheel 7 to rotate.

[0022] To prevent slippage between the motor output shaft and the detection wheel 7, the outer surface of the detection wheel 7 is made of a material with a high coefficient of friction, such as rubber or plastic. Furthermore, the detection wheel 7 can be removed from the transmission rod 3 for replacement. Actual production experience shows that the detection wheel 7 can guarantee tens of thousands of error-free tests.

[0023] Two small cylinders, 4, are arranged symmetrically with their output shafts facing each other. A rack 5 is located between the two small cylinders 4, with both ends of the rack 5 abutting against the output shafts of the two small cylinders 4 respectively. A gear 8 is fixedly mounted on the transmission rod 3, located above the rack 5 and meshing with it.

[0024] The output shafts of the two small cylinders 4 were originally partially extended, resting against the left and right sides of the rack 5. When the transmission rod 3 rotates, it will drive the rack 5 to move through the gear 8.

[0025] The testing platform 1 is equipped with two proximity switches, which are also proximity sensors. The two proximity switches are a forward rotation detection proximity switch 9 and a reverse rotation detection proximity switch 10, located on either side of the front end of the rack 5. When the rack 5 moves to one side, it passes over the contact switch at that position, allowing the controller to determine whether the motor is rotating forward or reverse. Operators can also determine the motor's direction of rotation simply by observing the direction the rack 5 moves.

[0026] To ensure smooth movement of the rack 5, a slider 13 is welded to the lower end face of the rack 5, and a slide rail 14 is fixed on the test table 1. The slide groove at the lower end of the slider 13 is fitted onto the slide rail 14, so that the slider 13 and the slide rail 14 slide together to reduce friction and shaking.

[0027] The switch testing mechanism is located on the other side of the testing platform 1 and is used to test the function of the two switches. The mechanism includes a fixed platform 2 11, which has a fixed slot 2 for placing the circuit boards containing the two switches.

[0028] Two detection cylinders 12 are fixed on the fixed platform 2 11, and the two detection cylinders 12 are located at one end of the two switches respectively. When the circuit board is placed in the fixed slot 2, the output shaft of the detection cylinder 12 can be pushed forward to press the corresponding switch, simulating the use state of the switch, thereby detecting whether the switch is conducting and functioning normally.

[0029] In addition, the switch detection mechanism also includes a small cylinder 15, which is fixed on the fixed platform 11. An L-shaped locking block 16 is provided on its output shaft. The small cylinder 15 can push the locking block 16, so that one side of the locking block 16 presses against the upper side of the circuit board, thereby fixing the circuit board in the fixed groove and preventing the circuit board from moving during the detection process.

[0030] The entire testing process is as follows: First, the wiring terminals of the wire harness are fixed on the terminal fixing mechanism, and the motor is snapped into the fixing slot 1 of fixing platform 2. The switch circuit board is placed into the fixing slot 2 of fixing platform 2 and pressed down with locking block 2 16. Then, the motor testing mechanism and the switch testing mechanism are driven by an external control system.

[0031] In the motor testing mechanism, the forward and reverse rotation of the motor is determined by which contact switch's detection position is blocked by rack 5. In the switch testing mechanism, two detection cylinders 12 press the switch sequentially to detect the switch's response. All test results can be recorded via sensors or manual observation to ensure the functional integrity of the wiring harness assembly.

[0032] This utility model has a reasonable structure and is easy to operate, enabling it to perform tests on motors and switches, thereby improving testing efficiency and accuracy.

[0033] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
