[0032] The positioning assembly 2 is provided with a limiting clamping groove 21, and the wire harness head is detachably arranged in the limiting clamping groove 21.
[0033] The testing assembly 3 is slidably arranged on one side of the positioning assembly 2, and a testing interface 31 is arranged at one end close to the positioning assembly 2.
[0034] The driving assembly 4 is used for driving the testing assembly 3 to approach or move away from the positioning assembly 2.

Specifically, before the wire harness is tested, the wire harness head to be tested is installed in the limiting clamping groove of the positioning assembly. The limiting clamping groove ensures that the wire harness head is stably and accurately installed in the positioning assembly, so as to avoid test errors caused by shaking or displacement of the wire harness head during the test. When the wire harness is tested, the driving assembly drives the testing assembly to approach the positioning assembly along a predetermined track from an initial position. With the approach of the testing assembly, the position of the testing interface corresponds to the wire harness head arranged in the limiting clamping groove, and gradually accurately docks with the wire harness head to start the detection process. After the test is completed, the driving assembly drives the testing assembly to move away from the positioning assembly and return to the initial position, so as to perform the next test.
[0036] The key of the present application is to provide a wire harness measuring device, which positions the wire harness head through the limiting clamping groove in the mechanical structure, drives the testing assembly to slide through the driving assembly, so as to connect or disconnect the testing interface with the wire harness head, and starts the test process after the wire harness head and the testing interface are aligned. The wire harness measuring device realizes a fast and accurate test process through the driving assembly and the slidable testing assembly, greatly improves the test efficiency, and reduces the operation time and cost.

In summary, the wire harness measuring device provided by the present application can accurately position the wire harness head, and efficiently, accurately and reliably measure various performances of the wire harness.
[0037] It is worth noting that after the test interface is successfully connected with the wire harness head, the specific control process of the power on / off of the test assembly, the comparison of test data, the judgment of test results, and the like, the test time, the data processing method, and the like can be implemented by using the existing technology, and the PLC and the like connected by the test assembly can edit the logic device, and thus will not be described herein. For example, the test assembly starts to turn on the power and send a test signal, and the power current and the test signal sent are transmitted to the wire harness inside through the wire harness head to detect the connectivity, insulation, or other related performance of the wire harness. The test assembly collects and processes the test data returned from the wire harness head, and then compares the test data with the preset standard value. According to the comparison result, the test assembly can judge whether the wire harness is qualified.

[0040] In this embodiment, on the one hand, the test assembly is slidably arranged on the guide rails through the sliding channel, so that the test assembly can more smoothly slide along the guide rails under the driving of the driving assembly; on the other hand, by arranging the guide rails on the base, the preset movement track of the test assembly is further determined, so that the movement of the test assembly is more accurate, and the wire harness head is connected, thereby realizing a fast and accurate test process and greatly improving the test efficiency and accuracy.

[0042] The guide rail 12 is provided with a limiting block 13 at an end away from the test interface 31.
[0043] In this embodiment, a limiting plate is added above the test interface. On the one hand, when the driving assembly drives the test assembly to approach the positioning assembly, since the distance between the limiting plate and the bottom plate is less than or equal to the height of the positioning assembly, and the length of the limiting plate is greater than the length of the test assembly, the limiting plate will abut against the positioning assembly first, thereby limiting and protecting the test assembly. On the other hand, the length of the limiting plate is greater than the length of the test assembly, and the limiting plate is arranged above the test assembly, so as to avoid impurities such as debris and dust from polluting or blocking the interface during the test process, effectively protect the cleanliness and integrity of the test interface, and thus improve the service life and test precision of the test assembly. The guide rail is provided with a limiting block at the end away from the test interface, the running range of the test assembly is accurately controlled, the running range of the test assembly is accurately controlled, and the test assembly is ensured to move stably between the limiting block and the limiting plate, so as to avoid accidental collision or excessive movement from damaging the test interface, improve the accuracy and consistency of the test process, and help to maintain the stability and accuracy of the test results.

[0049] In this embodiment, the limiting slot on the limiting assembly comprises a first limiting slot and a second limiting slot; when manufacturing or measuring the wire harness, the wire harness head is pressed into the limiting slot from top to bottom, at this time the wire harness head is clamped in the first limiting slot and the second limiting slot, by pre-setting the depth and width of the first limiting slot and the second limiting slot, the wire harness head can be accurately aligned with the test interface when the test assembly approaches, the structure is simple and easy to implement. More preferably, the depth of the first limiting slot and the second limiting slot is greater than the maximum installation thickness of the wire harness head in the limiting slot, so as to avoid the wire harness head jumping out of the limiting slot. More preferably, the first limiting slot and the second limiting slot are perpendicular to each other, so as to better adapt to the structural characteristics of the wire harness head and achieve better limiting effect.
[0050] Preferably, the test assembly 3 further comprises a protective plate and a test line connected with the test interface; the test line is connected with the test interface 31; the protective plate is rotatably arranged above the test line.

As for the specific performance of the wire harness head that needs to be tested and the performance index, they can be set by the person skilled in the art according to the needs. The rotatable protective plate arranged above the test line can act as a barrier to prevent dust, debris and other impurities from falling onto the test line, thereby reducing electrical failures and signal interference caused by pollution or damage, and reducing the risk of accidental damage to the test line during equipment operation and maintenance. On the other hand, the protective plate adopts a rotatable structure, which can flexibly adjust the position of the protective plate, so that it can cover the test line for protection when needed, and can be rotated away when the test line is being repaired or operated, greatly improving the convenience of maintenance. More preferably, the protective plate is made of transparent insulating material; while providing electrical insulation protection, it maintains the transparency of the line of sight, so that the operator can observe the state of the test line at any time without the need to remove the protective plate. Optionally, the protective plate is made of acrylic or polycarbonate material.

[0054] The second end of the connecting plate 42 is hinged to the base 1, and the third end of the connecting plate 42 is connected with the handle 43.
[0055] In this embodiment, when the wire harness is tested, the handle is rotated in the first direction, and through the transmission of the connecting plate and the connecting rod, the test assembly is driven to approach the positioning assembly, so that the wire harness head is accurately connected to the test interface; after the wire harness is tested, the handle is rotated in the second direction, and through the transmission of the connecting plate and the connecting rod, the test assembly is driven to move away from the positioning assembly, so that the wire harness head is separated from the test interface. It can be understood that the external force driving the handle can be manually provided by the operator, or can be provided by a motor, a rotary cylinder or the like. More preferably, the ratio of the distance between the first end and the second end of the connecting rod to the distance between the first end and the second end of the connecting plate is 3:1; to ensure the compactness of the driving assembly structure, while taking into account the transmission effect.
