Description

Technical Field

[0001] This utility model relates to the field of automotive wiring harness technology, and specifically to an automotive wiring harness testing device. Background Technology

[0002] Automotive wiring harnesses are a core component of a vehicle's electrical system, responsible for distributing electrical energy, signals, and data to various electronic components throughout the vehicle. The basic structure of the wires is made of copper or aluminum, with the cross-sectional area selected according to current / signal requirements, and some use high-frequency coaxial cables.

[0003] In the prior art, such as the automotive wiring harness testing device with announcement number CN223021759U, there is a frame; a pulling mechanism, which is disposed on the frame and includes a clamping seat and a driving member connected by transmission, wherein the clamping seat is used to clamp and fix one end of the wiring harness body, and the driving member is used to drive the clamping seat to move along a first direction; and a limiting seat, which is disposed on the frame and distributed opposite to the clamping seat along the first direction, and the limiting seat is provided with a limiting mechanism.

[0004] In the above, the limiting mechanism is used to abut the terminal and limit the displacement of the terminal toward the clamping seat in the first direction, which basically realizes the stable alignment function of the wire harness. However, after reading the technical solution, it is found that there are many wire harnesses in automobiles, and the installation positions and heights are different. This device can only meet the testing of wire harnesses on a straight line and cannot meet the testing needs of wire harnesses at different heights. A device that can flexibly adjust the test height should be set up so that all wire harnesses can be tested. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an automotive wiring harness testing device that can effectively solve the problem that the existing technology cannot meet the testing requirements of wiring harnesses of different heights.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides an automotive wiring harness testing device, including a base, a pressing panel placed on the top of the base, a side rod adapted to be installed on the outer side of the pressing panel, a limiting cylinder slidably connected to the bottom of the side rod, the limiting cylinder being fixedly connected to the upper surface of the base, and the pressing panel being equipped with an alignment component. The alignment component includes a push rod slidably mounted on the bottom of the pressing panel. A straight spring is sleeved on the outer surface of the push rod. An upper alignment seat is fixedly connected to the lower surface of the straight spring. A lower alignment seat is symmetrically arranged on the upper alignment seat. The lower alignment seat is fixedly connected to the top of the base. A wire harness abuts between the lower alignment seat and the upper alignment seat. The wire harness is equipped with a repetitive testing component.

[0007] Furthermore, the repeated testing assembly includes an adapter slot plate snapped onto the outer surface of the wire harness, a threaded sleeve is connected through the outer surface of the adapter slot plate, a screw is threaded onto the inner surface of the threaded sleeve, and a drive source is fixedly connected to the end face of the screw.

[0008] Furthermore, the sliding stroke of the limiting cylinder is greater than the compression distance of the straight spring. The increased sliding stroke can be used to stabilize the pressing panel, while also ensuring the full stretching and compression of the straight spring.

[0009] Furthermore, the adapter plate has an inner opening slot, the vertical height of which is slightly less than the diameter height of the wire harness.

[0010] Furthermore, an ear plate is fixedly connected to the outer side of the adapter slot plate, and a sliding support is slidably fitted on the surface of the ear plate.

[0011] Furthermore, the adapter slot plate is fitted with a hole position adjustment component, which includes a smooth block adapted to be installed on the lower surface of the adapter slot plate. The smooth block engages with a linear toothed plate, and a torsion spring is placed on the side of the smooth block. A stand is rotatably connected to the outer surface of the torsion spring.

[0012] Furthermore, there are two torsion springs, and a hinged connecting plate is installed on the side of the two torsion springs that are close to each other. A plug is sleeved at the corner of the hinged connecting plate, and a hole plate is fixedly connected to the top of the hinged connecting plate. One side of the hole plate is set corresponding to the wire harness.

[0013] Furthermore, the hole adjustment component also includes a right-angle block fixedly connected to the outer side of the hinge plate, and an inner sliding frame is slidably connected to one side of the right-angle block.

[0014] Beneficial effects The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. The elastic force of the straight spring allows the displacement direction of the upper seat to be consistent with the direction of the elastic force, thereby enabling the upper surface of the wire harness to achieve a contact effect. This allows wire harnesses of different heights to be contacted and participate in the test. Furthermore, considering that the straight spring is a soft component, it will not cause damage to the wire harness when applying elastic force. At the same time, the pressing panel is an active force-applying component, and the force intensity of the pressing panel can be flexibly adjusted according to the specific requirements of the wire harness test, which can speed up the pressing speed of wire harnesses of different heights and help shorten the wire harness docking time. 2. Install the adapter slot plate by snapping it onto the outer surface of the wire harness. Tighten the screw sleeve on the outer surface of the adapter slot plate. At the same time, start the drive source. The drive source drives the screw to rotate synchronously, which further displaces the screw sleeve and the adapter slot plate along the surface of the screw. Since the adapter slot plate and the wire harness are snapped together, the displacement of the adapter slot plate can pull the wire harness to move in the same direction, thereby allowing the wire harness to quickly approach the hole adjustment part for wire harness connection testing.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The present invention will be further described below with reference to the embodiments.

[0020] See attached document Figure 1-5 An automotive wiring harness testing device includes a base 1, a pressing panel 2 placed on the top of the base 1, a side rod 3 adapted to be installed on the outer side of the pressing panel 2, a limiting cylinder 4 slidably connected to the bottom of the side rod 3, the limiting cylinder 4 being fixedly connected to the upper surface of the base 1, and the pressing panel 2 being fitted with an alignment component 5. The alignment component 5 includes a push rod 51 that is slidably installed at the bottom of the pressing panel 2. A straight spring 52 is sleeved on the outer surface of the push rod 51. An upper alignment seat 53 is fixedly connected to the lower surface of the straight spring 52. A lower alignment seat 54 is symmetrically arranged on the upper alignment seat 53. The lower alignment seat 54 is fixedly connected to the top of the base 1. A wire harness 6 abuts between the lower alignment seat 54 and the upper alignment seat 53. The wire harness 6 is equipped with a repetitive testing component 7.

[0021] First, force is applied to the pressing panel 2, causing it to slide stably towards the inner cavity of the limiting cylinder 4 under the sliding support of the side rod 3. Then, the pressing panel 2 continues to press down. When it contacts the straight spring 52, the straight spring 52 is compressed and generates elastic force. The elastic force further pulls the push rod 51, causing the upper positioning seat 53 to move downward. Through the elastic force of the straight spring 52, the displacement direction of the upper positioning seat 53 can be kept consistent with the direction of the elastic force, thereby allowing the upper surface of the wire harness 6 to achieve a contact effect. This allows wire harnesses 6 of different heights to be contacted and participate in the test. Furthermore, considering that the straight spring 52 is a soft part, applying elastic force to the wire harness 6 will not cause damage to the wire harness 6. At the same time, the pressing panel 2 is an active force-applying component, and the force intensity of the pressing panel 2 can be flexibly adjusted according to the specific requirements of the wire harness 6 test, accelerating the pressing speed of wire harnesses 6 of different heights, which is beneficial to shorten the connection time of the wire harness 6.

[0022] The repeatedly tested component 7 includes an adapter slot 71 that is snapped onto the outer surface of the wire harness 6. A threaded sleeve 72 is connected through the outer surface of the adapter slot 71. A screw 73 is threaded onto the inner surface of the threaded sleeve 72. A drive source 74 is fixedly connected to the end face of the screw 73. The sliding stroke of the limiting cylinder 4 is greater than the compression distance of the straight spring 52. The increase in the sliding stroke can be used to press the panel 2 down stably, while also ensuring the full stretching and compression of the straight spring 52.

[0023] Then, the adapter slot plate 71 is snapped onto the outer surface of the wire harness 6, and the screw sleeve 72 is tightened on the outer surface of the adapter slot plate 71. At the same time, the drive source 74 is started, and the drive source 74 drives the screw 73 to rotate synchronously, further displacing the screw sleeve 72 and the adapter slot plate 71 along the surface of the screw 73. Furthermore, since the adapter slot plate 71 and the wire harness 6 are snapped together, the displacement of the adapter slot plate 71 can pull the wire harness 6 to move in the same direction, thereby allowing the wire harness 6 to quickly approach the hole adjustment part 77 for the connection test of the wire harness 6. Through the transmission cooperation between the drive source 74 and the screw 73, the wire harness 6 achieves the effect of cyclic displacement, which reduces the pause required to adjust the distance when switching test types and improves the applicability of the test range of the wire harness 6.

[0024] The adapter slot 71 has an inner opening slot, the vertical height of which is slightly less than the diameter height of the wire harness 6. An ear plate 75 is fixedly connected to the outer side of the adapter slot 71, and a sliding support 76 is slidably fitted on the surface of the ear plate 75.

[0025] By setting the size of the inner opening groove to be smaller than that of the wire harness 6, the wire harness 6 can be stably snapped into the side of the inner opening groove, which further ensures the displacement stability of the wire harness 6 and indirectly improves the docking stability between the wire harness 6 and the hole adjustment component 77.

[0026] The adapter slot plate 71 is fitted with a hole position adjustment component 77. The hole position adjustment component 77 includes a smooth block 771 that is fitted and installed on the lower surface of the adapter slot plate 71. The smooth block 771 is engaged with a linear toothed plate 772. A torsion spring 774 is placed on the side of the smooth block 771. A stand 773 is rotatably connected to the outer surface of the torsion spring 774.

[0027] When the adapting slot plate 71 slides, the bottom smooth block 771, under the constraint of the linear toothed plate 772, smoothly moves towards the hinged connecting plate 775, thereby changing the height of the hole plate 777, which is beneficial for the hole plate 777 to better contact and detect the wire harness 6.

[0028] There are two torsion springs 774. A hinge plate 775 is installed on the side of the two torsion springs 774 that are close to each other. A plug rod 776 is sleeved at the corner of the hinge plate 775. A hole plate 777 is fixedly connected to the top of the hinge plate 775. One side of the hole plate 777 is set corresponding to the wire harness 6.

[0029] By setting torsion springs 774 on both sides of the hinge plate 775, the rotation of the hinge plate 775 is supported by the rotational force of the torsion springs 774, thereby allowing the hole plate 777 to remain relatively stationary.

[0030] The hole adjustment component 77 also includes a right-angle block 778 fixedly connected to the outer side of the hinge plate 775, and an inner sliding frame 779 is slidably connected to one side of the right-angle block 778.

[0031] Finally, the sliding connection between the right-angle block 778 and the inner sliding frame 779 ensures that the top of the hinge plate 775 maintains a vertical displacement motion, thus ensuring that the vertical displacement of the hole plate 777 is more continuous and stable.

[0032] Working principle: First, force is applied to the pressing panel 2, causing it to slide stably towards the inner cavity of the limiting cylinder 4 under the sliding support of the side rod 3. Then, the pressing panel 2 continues to press down. When it comes into contact with the straight spring 52, the straight spring 52 is compressed and generates elastic force. The elastic force further pulls the push rod 51, causing the upper positioning seat 53 to move downward. Through the elastic force of the straight spring 52, the displacement direction of the upper positioning seat 53 can be kept consistent with the direction of the elastic force, thereby allowing the upper surface of the wire harness 6 to achieve a contact effect. This allows wire harnesses 6 of different heights to be contacted and participate in the test. Furthermore, considering that the straight spring 52 is a soft part, applying elastic force to the wire harness 6 will not cause damage to the wire harness 6. At the same time, the pressing panel 2 is an active force-applying component, and the force intensity of the pressing panel 2 can be flexibly adjusted according to the specific requirements of the wire harness 6 test, accelerating the pressing speed of wire harnesses 6 of different heights, which is beneficial to shorten the connection time of the wire harness 6. Then, the adapter slot plate 71 is snapped onto the outer surface of the wire harness 6, and the screw sleeve 72 is tightened on the outer surface of the adapter slot plate 71. At the same time, the drive source 74 is started, and the drive source 74 drives the screw 73 to rotate synchronously, further displacing the screw sleeve 72 and the adapter slot plate 71 along the surface of the screw 73. Furthermore, since the adapter slot plate 71 and the wire harness 6 are snapped together, the displacement of the adapter slot plate 71 can pull the wire harness 6 to move in the same direction, thereby allowing the wire harness 6 to quickly approach the hole adjustment part 77 for the connection test of the wire harness 6.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
