Description

Technical Field

[0001] This utility model relates to the field of wire harness processing technology, specifically to a wire harness conductor continuity detection device. Background Technology

[0002] Automotive wiring harnesses are a core component of automotive circuits, consisting of multiple wires, connectors, terminals, and other elements. They are mainly used to transmit electrical signals and supply power between various electronic devices and control systems within the vehicle, and are key connection components that ensure the normal operation of various automotive functions.

[0003] The wiring harness continuity test bench is a device specifically designed for automotive wiring harness production and quality inspection. It is used to test the continuity of the wires inside the wiring harness and determine whether there are problems such as open circuits, short circuits, or incorrect connections, so as to ensure that the electrical performance of the wiring harness meets the design standards. It is an important testing tool to ensure the quality of automotive wiring harnesses.

[0004] In existing wire harness continuity testing stations, the keyboard, mouse, and printer used for operation and control, as well as the printer that outputs the test results, are usually located at the top and rear of the testing station. Since the wire harness to be tested is tree-shaped, the width of the continuity testing station is usually large, which makes the printer and keyboard and mouse far away from the operator. This means that the operator usually has to stretch out to reach them, and for shorter people, they may need to stand on tiptoe to operate. This not only increases the difficulty of operation, but also poses a risk of falling due to loss of balance. Falls may damage the wire harness to be tested or the assembled wire harness. Most importantly, if the operator's body falls on the wire harness, they can easily be injured by the wire harness clips, connectors, and test components, affecting testing efficiency and safety. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a wire harness continuity detection device to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wire harness continuity testing device, comprising a wire harness continuity testing platform, wherein two guide rails are fixed on both sides of the top of the wire harness continuity testing platform, and limit blocks are connected to both sides of the two guide rails; a bracket is connected between the two guide rails, and multiple rollers are connected to the lower outer surface and the lower back of the bracket respectively; a frame is connected to the top of the bracket, and two buffer pads are connected to the inner side of the frame, and an anti-slip pad is connected to the top of the frame.

[0007] By adopting the above technical solution, the guide rail provides a stable installation foundation and guidance for the bracket, the limit block restricts the range of movement of the bracket, and the bracket moves left and right along the guide rail via rollers, making it easy for staff to adjust the position of the printer, keyboard and mouse according to operational needs. The frame, buffer pad and anti-slip pad can protect the equipment placed on the bracket and reduce equipment falling or collision damage. The overall structure improves the convenience of operation and the stability of equipment use. At the same time, the hollow design at the bottom of the bracket reduces interference with the disassembly and assembly of automotive wiring harnesses.

[0008] Furthermore, the roller is connected to the guide rail, and the longitudinal section of the guide rail is U-shaped.

[0009] By adopting the above technical solution, the U-shaped guide rail can effectively limit the rollers, ensuring that the bracket moves smoothly only in the left and right directions and avoiding forward, backward or up and down deviations; the cooperation between the rollers and the guide rail can reduce the frictional resistance when the bracket moves, making the bracket position adjustment easier and smoother.

[0010] Furthermore, the anti-slip mat is made of silicone rubber.

[0011] By adopting the above technical solution, silicone rubber material has good anti-slip properties, which can increase the friction between the printer and keyboard and the stand, reduce the sliding displacement of the equipment due to inertia during the movement of the stand, and improve the stability of the equipment placement.

[0012] Furthermore, the cushioning pad is made of thermoplastic elastomer material.

[0013] By adopting the above technical solution, thermoplastic elastomers have good elasticity and cushioning performance. When printers, keyboards, or mice move left and right due to inertia, they can buffer the collision force between them and the frame, reducing damage to the equipment.

[0014] Furthermore, the cross-section of the frame is shaped like an "U", and the height of the outer surface of the frame is lower than the height of the back of the frame.

[0015] By adopting the above technical solution, the U-shaped frame can form a barrier around the equipment from all sides. The higher back and sides can reduce the possibility of the equipment falling off from the left, right and back, while the lower front can reduce the obstruction of the operator's keyboard and mouse operation, thus balancing protection and ease of operation.

[0016] Furthermore, the limiting block is detachably connected to the guide rail via bolts.

[0017] By adopting the above technical solution, the bolt connection method facilitates the disassembly and assembly of the limit block, which can effectively limit the movement range of the bracket to reduce derailment, and also allows for easy disassembly of the limit block when the bracket needs to be replaced or the guide rail needs to be maintained, thus improving the convenience of equipment maintenance.

[0018] Furthermore, the anti-slip pad is connected to the bracket by adhesive bonding, and the cushioning pad is connected to the frame by adhesive bonding.

[0019] By adopting the above technical solution, the adhesive connection method is simple to operate, can ensure the stable fixation of the anti-slip pad and the buffer pad, and is easy to replace in the future due to wear and tear, thus ensuring its long-term use effect.

[0020] Furthermore, a monitor and multiple covers are installed on the top of the wire harness continuity test stand, and the covers are detachably connected to the wire harness continuity test stand. A printer, keyboard, and mouse are placed on the top of the anti-slip pad.

[0021] By adopting the above technical solution, the monitor can display the wire harness continuity test data in real time, which is convenient for staff to observe; the cover plate can be removed to install the test ports of different types of wire harnesses; the printer, keyboard and mouse are placed on the anti-slip pad, and the mobility of the bracket improves the convenience of operation and the efficiency of testing.

[0022] Furthermore, the outer ring of the roller is provided with a groove, and a rubber sleeve is connected inside the groove. The cross-section of the rubber sleeve is "T" shaped.

[0023] By adopting the above technical solution, the T-shaped rubber sleeve contacts the inner wall of the guide rail. Its elastic properties can reduce the rigid friction between the roller and the guide rail, reduce the noise when the support moves, and at the same time buffer the vibration caused by the slight unevenness of the guide rail surface, making the support and equipment move more smoothly.

[0024] Furthermore, a cable chain is installed on one side of the top of the wire harness continuity test stand, and one end of the cable chain is connected to the bracket. The cable chain contains cables, and the cables inside the cable chain are electrically connected to the wire harness continuity test stand, printer, keyboard and mouse respectively.

[0025] By adopting the above technical solution, the cable chain deforms synchronously with the movement of the bracket, which can wrap and protect the internal cables, reduce the entanglement, pulling or friction of the cables caused by the movement of the bracket, reduce the risk of cable damage, and ensure the stability of the electrical connection between the printer, keyboard, mouse and test station.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model, through the arrangement of guide rails, limiting blocks, brackets, and rollers, places the bracket above the wiring harness, with the printer, keyboard, and mouse positioned on top of the bracket. This allows operators to operate without stretching or standing on tiptoe, reducing operational difficulty. Furthermore, the bracket's open bottom minimizes interference with the disassembly and assembly of the automotive wiring harness. If operators feel the bracket is affecting the disassembly or assembly work, they can gently slide it to move it above an already assembled area or an open area. The operation is simple, convenient, and time-saving. During operation, the guide rails provide stable left-right guidance, ensuring the bracket can only move in the left-right direction. The rollers rolling within the guide rails reduce resistance during bracket translation, allowing operators to flexibly adjust the bracket's position. The limiting blocks, bolted to both ends of the guide rails, reduce the risk of the bracket derailing and improve the overall structural stability.

[0028] 2. This utility model features a frame with a U-shaped cross-section. The sides and back are relatively high, which prevents the printer, keyboard, and mouse from falling off from the sides and back. The front of the frame is relatively low, which reduces the possibility of the keyboard and mouse falling forward and also reduces the impact on the operator's hands, thus balancing protection and ease of operation.

[0029] 3. This utility model incorporates anti-slip pads and cushioning pads. The anti-slip pads, made of silicone rubber and bonded to the top of the bracket, reduce the sliding displacement of the printer and keyboard on the bracket during horizontal movement, thus improving the stability of the equipment. The cushioning pads, made of thermoplastic elastomer and bonded to the inside of the frame, reduce the impact of large inertia on the equipment and overcome the damage caused by collision with the frame when the equipment moves left or right due to friction with the anti-slip pads, providing a certain degree of protection for the printer, keyboard, and mouse.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0037] The embodiments of this utility model will be described below based on its overall structure.

[0038] Example 1:

[0039] A wire harness continuity detection device, such as Figures 1-5As shown, the system includes a wire harness continuity testing platform 1. Two guide rails 7 are fixed to the top of the platform 1 on both sides. The longitudinal section of each guide rail 7 is U-shaped. Limiting blocks 8 are connected to both sides of each guide rail 7, and the limiting blocks 8 are detachably connected to the guide rails 7 by bolts. A bracket 9 connects the two guide rails 7. Multiple rollers 10 are connected to the lower outer surface and the lower back of the bracket 9, respectively. The rollers 10 are connected to the guide rails 7. During operation, the keyboard 5, mouse 6, and printer 4, used for operation and control, and outputting test results, are placed on top of the bracket 9. Operators can adjust the position of the bracket 9 to place the keyboard 5 and mouse 6 within a comfortable operating range, allowing them to be reached without stretching or standing on tiptoe, greatly improving operational convenience. A frame 12 is connected to the top of the bracket 9. The frame 12 has a U-shaped cross-section. The height of the outer surface of the frame 12 is lower than the height of the back of the frame 12. The frame 12 at the top of the bracket 9 has a U-shaped cross-section, and the sides and back of the frame 12 are higher, effectively protecting the printer 4, keyboard 5, and mouse 6 placed on the bracket 9 and preventing them from... The printer 4, keyboard 5, and mouse 6 may detach from the sides and back. The lower front of the frame 12 avoids obstructing the operator's hand movements when using the keyboard 5 and mouse 6, while also reducing the likelihood of the devices detaching forward, thus balancing protection and ease of operation. Two cushioning pads 14, made of thermoplastic elastomer, are attached to the inner side of the frame 12. When the printer 4, keyboard 5, or mouse 6 shifts left or right due to inertia overcoming the friction of the anti-slip pads 13, the cushioning pads effectively buffer the collision with the frame 12, reducing damage. An anti-slip pad 13, made of silicone rubber, is attached to the top of the frame 12 and is bonded to the bracket 9. This increases the friction between the printer 4 and keyboard 5 and the bracket 9, reducing the sliding displacement of these devices due to inertia during the translation process and ensuring the stability of the equipment.

[0040] See Figure 1 and Figure 2 In the above embodiment, the top of the wiring harness continuity test bench 1 is equipped with a display 3 and multiple cover plates 2. The wiring harness continuity test bench 1 serves as the overall base, and the cover plates 2 on its top can be removed as needed to facilitate the placement of test ports for connecting automotive wiring harnesses. That is, different models of wiring harnesses use different port combinations, and the empty spaces are closed with cover plates 2. The wiring harness continuity test bench 1 detects the continuity status of automotive wiring harnesses, and the test data is displayed on the display 3 in real time. The cover plates 2 are detachably connected to the wiring harness continuity test bench 1. A printer 4, a keyboard 5, and a mouse 6 are placed on the top of the anti-slip pad 13. The operator issues test commands to the test bench through the keyboard 5 and the mouse 6. After the test is completed, the printer 4 can output the corresponding test results.

[0041] Example 2:

[0042] Based on the above embodiment 1, in order to enhance the performance of the roller 10, the following settings are now implemented.

[0043] See Figure 4 In the above embodiment, the outer ring of the roller 10 is provided with a groove, and a rubber sleeve 11 is connected inside the groove. The cross-section of the rubber sleeve 11 is "T" shaped. The elastic properties of the rubber sleeve 11 can buffer the vibration caused by the slight unevenness of the guide rail 7 surface when the bracket 9 moves, so that the bracket 9 and the printer 4, keyboard 5 and mouse 6 above it move more smoothly and reduce the noise generated during the movement of the bracket 9.

[0044] Example 3:

[0045] Based on the above embodiment one, in order to facilitate the displacement of the cable adapter bracket 9 for printer 4, keyboard 5 and mouse 6, the following settings are now adopted.

[0046] See Figure 1 In the above embodiment, a cable chain 15 is installed on one side of the top of the wire harness continuity test bench 1. One end of the cable chain 15 is connected to the bracket 9. Cables are installed inside the cable chain 15. The cables inside the cable chain 15 are electrically connected to the wire harness continuity test bench 1, the printer 4, the keyboard 5, and the mouse 6, respectively. The cable chain 15 deforms synchronously with the movement of the bracket 9 to protect the internal cables and reduce the possibility of the cables getting tangled, pulled, or rubbing against other components due to the movement of the bracket 9. This reduces the risk of cable damage and ensures that the electrical connection between the printer 4, the keyboard 5, the mouse 6, and the test bench remains stable, allowing the wired printer 4, the keyboard 5, and the mouse 6 to continue to work normally during the movement of the bracket 9. If the printer 4, the keyboard 5, and the mouse 6 use Bluetooth or wireless USB to transmit electrical signals and have their own rechargeable batteries, then the cable chain 15 is not required.

[0047] The implementation principle of this utility model is as follows: First, the wiring harness continuity test bench 1 serves as the overall base, and its top cover plate 2 can be disassembled as needed to facilitate the placement of the test ports for connecting automotive wiring harnesses. That is, different models of wiring harnesses are paired with different ports, and the empty spaces are closed with the cover plate 2. After that, the operator places the automotive wiring harness to be tested in a suitable position on the wiring harness continuity test bench 1, and then is ready to perform the continuity test operation. During the disassembly and assembly of the automotive wiring harness, since the bottom of the bracket 9 is hollow, it will not interfere with the disassembly and assembly of the wiring harness. The operator can also move the bracket 9 to the area where the wiring harness has been assembled or to an open area above the test bench, further improving the flexibility of operation.

[0048] During operation, the keyboard 5, mouse 6, and printer 4 for outputting test results are placed on top of the bracket 9. The operator adjusts the position of the bracket 9 to place the keyboard 5 and mouse 6 in a comfortable operating range. The operator sends test commands to the test bench through the keyboard 5 and mouse 6. The wiring harness continuity test bench 1 tests the continuity status of the automotive wiring harness. The test data is displayed on the monitor 3 in real time. It can be accessed without stretching or standing on tiptoe, which greatly improves the convenience of operation. After the test is completed, the printer 4 can output the corresponding test results.

[0049] During this period, the longitudinal section of the guide rail 7 is U-shaped, which provides a stable guiding effect for the bracket 9, ensuring that the bracket 9 can only move horizontally and horizontally, and cannot move forward, backward or up and down; the roller 10 rolls inside the guide rail 7, which can effectively reduce the resistance when the bracket 9 moves horizontally, so that the staff can easily push the bracket 9 to move left and right along the guide rail 7 according to their own operating position and habits.

[0050] When the bracket 9 moves horizontally along the guide rail 7 via the rollers 10, the elastic properties of the rubber sleeve 11 can buffer the vibration caused by the slight unevenness of the guide rail 7 surface during the movement of the bracket 9, making the movement of the bracket 9 and the printer 4, keyboard 5, and mouse 6 above it smoother and reducing the noise generated during the movement of the bracket 9; and when the bracket 9 moves left and right along the guide rail 7, the drag chain 15 will deform synchronously with the movement of the bracket 9 to protect the internal cables, reduce the possibility of the cables getting tangled, pulled or rubbing against other parts due to the movement of the bracket 9, reduce the risk of cable damage, and ensure that the electrical connection between the printer 4, keyboard 5, mouse 6 and the test platform remains stable, so that the wired printer 4, keyboard 5, mouse 6 can still work normally during the movement of the bracket 9; if the printer 4, keyboard 5, mouse 6 uses Bluetooth or wireless USB to transmit electrical signals and has its own battery for power, then the drag chain 15 is not required;

[0051] Furthermore, the limiting blocks 8 at both ends of the guide rail 7 can limit the movement range of the bracket 9, reducing the possibility of the bracket 9 derailing due to excessive movement during translation, ensuring the stability and safety of the bracket 9 during movement. When the bracket 9 needs to be replaced in the future, the limiting blocks 8 can be removed and the bracket 9 can be pulled out from the side of the guide rail 7 to complete the disassembly and replacement.

[0052] The frame 12 at the top of the bracket 9 has a U-shaped cross-section. The sides and back of the frame 12 are relatively high, which can effectively protect the printer 4, keyboard 5 and mouse 6 placed on the bracket 9, preventing the printer 4, keyboard 5 and mouse 6 from falling off from the sides and back. The front of the frame 12 is relatively low, which will not hinder the hand movements of the operator when operating the keyboard 5 and mouse 6, and can also reduce the possibility of the equipment falling forward to a certain extent, thus balancing the protective effect and the ease of operation.

[0053] The top of the bracket 9 is bonded with an anti-slip pad 13 made of silicone rubber, which increases the friction between the printer 4 and keyboard 5 and the bracket 9, reducing the sliding displacement of these devices due to inertia during the translation process of the bracket 9, and ensuring the stability of the device placement. The buffer pad 14 bonded to the inside of the frame 12 is made of thermoplastic elastomer material. When the printer 4, keyboard 5 or mouse 6 moves left or right due to the friction of the anti-slip pad 13 due to greater inertia, the buffer pad 14 can effectively buffer the collision between them and the frame 12, reducing the damage to the device. If the anti-slip pad 13 and the buffer pad 14 are damaged, the staff can use a scraper to remove the remaining anti-slip pad 13 and the buffer pad 14 and re-bond new anti-slip pad 13 and the buffer pad 14, ensuring the stability of the anti-slip pad 13 and the buffer pad 14 during operation and the feasibility of subsequent disassembly and replacement.

The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
