[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 A wiring harness testing tool comprises a base 1, a mounting block 2 for clamping the wiring harness is provided on the base 1, a mounting seat 4 is provided on one side of the mounting block 2, and a test plug 3 is movably provided in the mounting seat 4.

[0022] The base 1 is provided with a total interface test module, an end row crimping test module, a total interface and an end row connector of the tested wiring harness, and the wiring harness between the above structures forms a loop for conduction detection. A power supply is connected in series to the internal loop of the base 1. The principle of the conduction test is: the power supply outputs a positive value to each contact of the wiring harness in sequence. Since a positive value is output to the detection point while a negative value is output to the other detection points, the detection point at the other end of the connecting line outputs a positive value, which means it is conductive. If the logic value at the input is a negative value, this point will be disconnected from the point that outputs a negative value. The conduction test is a common means in this technical field. The key point of the new utility model lies in the setting of the wiring harness test tooling structure.

[0023] A driving device 5 is provided in the mounting seat 4, and the driving device 5 is used to drive the test plug 3 to extend and retract on the mounting seat 4. The driving device 5 includes a mounting plate 51 connected to the mounting end of the test plug 3, and a support bar 52 is hinged at one end of the mounting plate 51 away from the test plug 3, and a turntable 53 for pushing the support bar 52 is hinged at the free end of the support bar 52, and the turntable 53 is provided on a rotating shaft 54 ​​for driving the turntable 53 to rotate. The mounting plate 51 is used to install the test plug 3, and one end of the support bar 52 is connected to the turntable 53 outside the rotating shaft 54. The test plug 3 is provided with four groups, and the test plug 3 moves through the side wall of the mounting seat 4, the turntable 53 rotates in the mounting seat 4, the rotating shaft 54 ​​is rotatably arranged in the mounting seat 4, the rotating shaft 54 ​​driving motor is arranged in the mounting seat 4, the mounting seat 4 is arranged on the base 1, and a cross through hole is arranged on the mounting seat 4.

[0024] The wiring harness main connector is clamped on the mounting block 2, and then the shaft 54 ​​is driven to rotate. The rotation of the shaft 54 ​​causes the turntable 53 to rotate accordingly. The turntable 53 rotates to push the support bar 52. The support bar 52 moves to push the mounting plate 51 to move outward, thereby pushing the test plug 3 to extend. The probe on the test plug 3 moves to contact the contact of the main connector, which is convenient for conducting a continuity test. This allows multiple groups of wiring harnesses to be tested at a single time, thereby improving the test efficiency.

[0025] A covering device 6 is provided on the top of the mounting seat 4 above the turntable 53, and the covering device 6 is used to cover the top opening of the mounting seat 4. The covering device 6 includes a cover plate 61 for moving and covering the top opening of the mounting seat 4, and a threaded hole 62 is provided on the cover plate 61. The threaded hole 62 is threadedly connected with a screw 63 for fixing the cover plate 61. The top area of ​​the cover plate 61 is less than or equal to the top area of ​​the mounting seat 4, and the bottom of the cover plate 61 is a smooth surface. There are at least four groups of threaded holes 62 and they are evenly distributed at the four corners of the cover plate 61, and one end of the screw 63 is threadedly connected to the mounting seat 4.

[0026] By turning the screw 63 and separating the screw 63 from the mounting base 4 and removing the cover plate 61 , the test plug 3 and the drive device 5 can be directly inspected and processed, so that the test plug 3 can be easily disassembled and assembled, and daily inspection and maintenance work can be easily performed.

[0027] Working principle: The utility model clamps the wiring harness main connector on the mounting block 2, and then drives the rotating shaft 54 ​​to rotate. The rotation of the rotating shaft 54 ​​causes the turntable 53 to rotate accordingly. The turntable 53 rotates to push the support bar 52. The support bar 52 moves to push the mounting plate 51 to move outward, thereby pushing the test plug 3 to extend. The probe on the test plug 3 moves and contacts with the contact of the main connector, which is convenient for conducting a conduction test, so that multiple groups of wiring harnesses can be tested at a time, thereby improving the test efficiency. Turn the screw 63. When the screw 63 is separated from the mounting seat 4 and the cover plate 61 is removed, the test plug 3 and the drive device 5 can be directly inspected and processed, making it easy to disassemble and assemble the test plug 3, making it easy to perform daily maintenance work.
