[0002] Automotive wiring harnesses are also an important part of the automotive production process, and they generally need to be tested after they are produced to determine their quality and performance. Although there are many types of automotive wiring harnesses, most of them are composed of cables in the middle and connectors at both ends, and although the cable connectors have different shapes, their width or diameter is generally much larger than the diameter of the cable in the middle.

[0003] At present, mature detectors are used for cable testing. During the test, workers need to accurately plug the positive connector of the wire harness into the positive connector of the wire harness detector, and accurately plug the negative connector of the wire harness into the negative connector of the wire harness detector, and then perform the test. After the test is completed, the workers unplug the wire harness connectors one by one. The whole process is manually plugged by workers, plugging the connectors at both ends of the car wire harness into the testing equipment one by one, which takes a long time and is cumbersome to operate, and the efficiency is low.

[0004] Since the detector detects very quickly, the main reason affecting efficiency is the wiring process of workers. For large quantities of automotive wiring harnesses in the workshop, the detection efficiency is poor, which can easily lead to failure to keep up with the production speed. Utility Model Content

[0032] The first aspect of the utility model is as follows Figure 1 , Figure 2 and Figure 3 As shown, the utility model mainly consists of a base 101, a detector 102 fixedly connected to the base 101, and a bearing wheel 107 rotatably connected to the base 101. The detector 102 is located directly below the bearing wheel 107. A pair of movable detection connectors 103 are also provided at the lower end of the detector 102. The two detection connectors 103 are located on both sides of the bearing wheel 107 and are used to test the wiring harness 01 through the detector 102 after docking with the wiring harness connector 02. The bearing wheel 107 is used to carry the wiring harness 01 for transportation.

[0033] Among them, a harness rack 108 is movably connected to the load-bearing wheel 107, and the harness rack 108 is provided with a plurality of groups (preferably four groups), and the plurality of groups of harness racks 108 are arranged at equal angles, and each group of harness racks 108 comprises relatively arranged movable parts, and the movable parts comprise a connecting member 109 and a movable end, and the movable end is slidably connected to a slide groove provided on the inner side of the load-bearing wheel 107, and one end of the connecting member 109 is fixedly connected to the movable end, and the other end of the connecting member 109 is fixedly connected to the corresponding limiting end.

[0034] Among them, the limiting end is a side plate, which is provided with a slot 110. The slot 110 is located on the outside of the load-bearing wheel 107. The inner diameter of the slot 110 is larger than the outer diameter of the wiring harness 01, and the outer diameter of the wiring harness connector 02 is larger than the inner diameter of the slot 110.

[0035] In addition, a driving member 114 is provided at the top position inside the load-bearing wheel 107, and the driving member 114 is fixedly connected to the base 101 and is located between two side plates in the uppermost harness frame 108;

[0036] Therefore, if Figure 5As shown, although the cable connectors have different shapes, their widths or diameters are generally much larger than the diameter of the cable in the middle. Therefore, by utilizing the feature that the inner diameter of the card slot 110 is larger than the outer diameter of the wire harness 01 and smaller than the outer diameter of the wire harness connector 02, the drive member 114 drives the wire harness frame 108 to expand, thereby tightening the wire harness 01 and fixing the wire harness connector 02, so as to facilitate the docking of the detection connector 103 with the wire harness connector 02.

[0037] Among them, one of the detection connectors 103 is electrically connected to the positive connector in the detector 102, and the other detection connector 103 is electrically connected to the negative connector in the detector 102, and a detection area is formed between the two detection connectors 103, so that after the harness rack 108 with the harness 01 is restricted moves into the detection area, the detector 102 detects the harness 01 through the connection between the detection connector 103 and the corresponding harness connector 02.

[0038] In addition, a micro-telescopic motor is arranged on the inner side of the detection connector 103, and the detection connector 103 is fixedly connected to the output shaft of the micro-telescopic motor. After the wiring harness connector 02 is supported and fixed by the side plate, the micro-telescopic motor drives the detection connector 103 to extend and dock with the wiring harness connector 02. After the detection is completed, the micro-telescopic motor drives the detection connector 103 to retract.

[0039] Specifically, Figure 3 As shown, a connecting tube 104 is fixedly connected to the base 101, the bearing wheel 107 is rotatably connected to the connecting tube 104, and a rotating shaft 105 is also rotatably connected to the base 101, the rotating shaft 105 passes through the connecting tube 104 and is fixedly connected to the output shaft of the driving motor in the base 101. A hub 106 is fixedly connected to the inner side of the bearing wheel 107, the hub 106 is fixedly connected to the rotating shaft 105, and the driving member 114 is located on the inner side of the hub 106.

The driving member 114 is located between the two connectors 109 in the uppermost harness rack 108, and there is a gap between the output shaft of the driving member 114 and the two connectors 109 when it is retracted, but the output shaft of the driving member 114 can resist the connector 109 when it is extended, and push the two connectors 109 to move outward, thereby expanding the harness rack 108 as a whole and achieving the effect of tightening the harness 01.

[0042] In particular, a return spring may be provided between the connector 109 and the load-bearing wheel 107, so that after the output shaft of the driving member 114 is contracted, the connector 109 can also automatically move inwards and return the harness rack 108 to the initial state. A suction cup may also be provided at the outer end of the output shaft of the driving member 114, so that when the output shaft of the driving member 114 is contracted, the connector 109 can be moved inwards to the initial position and the harness rack 108 can be returned to the initial state. DETAILED DESCRIPTION

[0043] This embodiment takes the arrangement of four groups of wire harness racks 108 arranged at equal angles as an example. First, the worker's operating station needs to be located directly in front of the wheel hub 106, that is, facing the wire harness rack 108 at the front position among the four preset positions. When the worker operates, he only needs to put the wire harness 01 into the card slot 110 of the side plate of the wire harness rack 108 at the front position, which is convenient and quick, greatly improving efficiency.

[0044] Then, the driving motor drives the wheel hub 106 to rotate periodically, 90° each time, and then stops. At this time, the harness rack 108 carrying the harness 01 will be transferred to the position directly above the four preset positions, where the driving member 114 and the detector 102 are provided, wherein the driving member 114 is located between the two side plates in the uppermost harness rack 108, and the detector 102 is located directly above the position, and the two detection connectors 103 at the lower end of the detector 102 are located on both sides of the position.

[0045] Then the driving member 114 is started, and the output shaft of the driving member 114 extends out, presses against the connecting member 109 and pushes the two connecting members 109 to move outward, thereby expanding the wiring harness frame 108 as a whole, tightening the wiring harness 01 and achieving the effect of fixing it.

[0046] Then the two detection connectors 103 at the lower end of the detector 102 extend out, and after docking with the harness connector 02, the harness 01 is tested through the detector 102. After the test is completed, the output shaft of the driving member 114 contracts, and through the suction cup at the outer end of the output shaft of the driving member 114, the connecting member 109 moves inward to the initial position, and the harness frame 108 is restored to the initial state.

[0047] Finally, the drive motor rotates 90° again and repeats the above operation process to detect the next wiring harness 01.

[0048] When the harness rack 108 carrying the harness 01 is transferred to the position directly below one of the four preset positions, the slot 110 faces downward, and the harness 01 will automatically fall off from the slot 110 .

[0049] Based on the above, the utility model is provided with a load-bearing wheel 107 and a harness rack 108 for placing the harness 01. The worker only needs to put the harness 01 into the slot 110, and the subsequent detection will be automatically performed, which is convenient and quick, and greatly improves the efficiency. And by utilizing the characteristics that the inner diameter of the slot 110 is larger than the outer diameter of the harness 01 and smaller than the outer diameter of the harness connector 02, the harness rack 108 is driven to expand through the driving member 114, and then the harness 01 is tightened, so as to facilitate the detection of the connection between the connector 103 and the harness connector 02. The detector 102 and the driving member 114 are also provided at the top, and at this time, the notch of the slot 110 faces upward to prevent the harness 01 from falling off from the slot 110, and by utilizing this point, when the load-bearing wheel 107 and the harness rack 108 rotate to the position where the notch of the slot 110 faces downward, the harness 01 will automatically fall off from the slot 110.
