Description

Technical Field

[0001] This utility model belongs to the technical field of wire harness testing, and in particular relates to a mobile tooling for testing and organizing wire harnesses. Background Technology

[0002] Wire harnesses are integrated circuits composed of multiple wires, cables, and connectors, and are widely used in the automotive, electronics, and aerospace industries to transmit power and signals. Wire speed testing fixtures are specialized equipment for testing the performance of wire harnesses. By simulating the actual working environment, they accurately test key parameters such as conductivity, insulation, withstand voltage, and signal transmission speed. They can quickly troubleshoot faults such as short circuits, open circuits, and poor contacts, ensuring that the wire harness meets design standards before assembly. They are an important tool for ensuring wire harness quality and safe equipment operation.

[0003] However, it still has the following drawbacks in actual use: When the test center tests the wire harness, it usually uses fixed wire trays or simple cable ties to bind the wire harness. Some solutions use static cable management racks, which require manual adjustment of the cable routing. The fixed wire trays cannot be adapted to mobile equipment, resulting in the wire harness being dragged and messy. The cable ties need to be repeatedly removed and removed, which is cumbersome and can easily damage the cables. It lacks dynamic adjustment capabilities. When the equipment location is changed, the wiring needs to be re-routed. The crossing of wire harnesses can easily cause signal interference and heat dissipation problems. Utility Model Content

[0004] The purpose of this utility model is to provide a mobile fixture for tidying up wire harnesses in a test center. By setting up a mobile tidying component, it solves the problems of messy wire harnesses, inconvenient movement, and troublesome wire end fixing in the test center, thereby improving the efficiency and safety of wire harness testing.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a mobile tool for tidying up wire harnesses in a test center, including a mobile tidying component and a wire end clamping component. The mobile tidying component includes a support frame, a set of movable wheels at the bottom of the support frame, a placement platform at the top of the support frame, a pusher fixed at one end of the support frame, and several hooks fixed on both sides of the support frame.

[0007] The bottom surface of the support frame has a guide rail, and a slider is slidably connected on the guide rail. A conduit is fixed on the upper surface of the slider. The conduit includes a bottom shell and a top cover hinged to the upper surface of the bottom shell. Magnetic buckles are provided at the open ends of the bottom shell and the top cover. A handle is also fixed on the upper surface of the top cover.

[0008] Furthermore, the movable wheel assembly includes omnidirectional wheels and directional wheels, with the pusher located on the side of the device near the directional wheels.

[0009] Furthermore, two sets of guide rails are arranged in parallel, and the two sets of guide rails are equipped with corresponding numbers and specifications of sliders, and the same conduit is fixed on the two corresponding sliders.

[0010] Furthermore, each conduit has ports at both ends, and a handle is provided on the top surface of the top cover at both ends of the conduit.

[0011] Furthermore, the wire end clamping assembly includes a base plate fixed to the upper surface of the slider. Clamping component one and clamping component two are rotatably connected to the upper surface of the base plate. Clamping component one and clamping component two have different specifications. Two spring rods are also hinged to the upper surface of the base plate, and the telescopic ends of the two spring rods are respectively hinged to the back sides of clamping component one and clamping component two.

[0012] Furthermore, both clamping surfaces of clamping member one and clamping member two are provided with universal balls, and universal balls are also provided on the inner wall of the conduit.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model, through its movable management component, allows the tooling to be pushed to the testing station by a pusher, adjusted to a suitable position using the movable wheels, and then the wire harness arranged. The magnetic buckle of the wire guide tube is opened, and the wire harness to be tested is passed through the port of the wire guide tube. The position of the wire guide tube on the guide rail is adjusted according to the testing requirements, and the top cover is closed to fix the wire harness, preventing the wire harness from tangling. This solves the problems of messy wire harnesses, inconvenient movement, and troublesome wire end fixing in the testing center, and improves the efficiency and safety of wire harness testing.

[0015] 2. This utility model features a wire end clamping assembly with clamping parts of different specifications, namely clamping part one and clamping part two, which can be adapted to wire harness ends of different thicknesses. In its natural state, the elasticity of the spring rod keeps the clamping parts in a closed clamping state. When the clamping parts are pulled outward, the spring rod stretches and stores force, and automatically resets after being released, thus achieving rapid clamping of the wire harness end. It can be adapted to wire harnesses with different inner diameters and solves the problem in the above solutions that the wire harness is prone to shrinking into the wire tube due to its own flexibility without fixing, resulting in a cumbersome secondary removal process.

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] Please see Figure 1-5 As shown, this utility model is a mobile tooling for tidying up wire harnesses in a testing center, including a mobile tidying component 1 and a wire end clamping component 2. The mobile tidying component 1 enables flexible transfer of the tooling, while the wire end clamping component 2 fixes the ends of wire harnesses of different specifications. At the same time, it works with the wire guide tube 17 to neatly store the wire harnesses. The mobile tidying component 1 includes a support frame 11, with a set of movable wheels 12 at the bottom of the support frame 11 and a placement platform 13 at the top of the support frame 11. A pusher 14 is fixed to one end of the support frame 11, and several hooks 111 are fixed to both sides of the support frame 11.

[0026] The support frame 11 serves as the main support structure of the entire tooling. A set of movable wheels 12 is installed at its bottom. The set of movable wheels 12 includes omnidirectional wheels 121 and directional wheels 122. A pusher 14 (such as a push rod) is fixed to the end of the support frame 11 on the side where the directional wheels 122 are located. When pushing, the directional wheels 122 ensure the stability of linear movement, while the omnidirectional wheels 121 facilitate turning. This is suitable for the movement needs of multiple areas within the test center. Hooks 111 are fixed to both sides of the support frame 11 and can hang small items such as test connection lines and labels to prevent tools from falling.

[0027] The bottom surface of the support frame 11 is provided with a guide rail 15, and a slider 16 is slidably connected to the guide rail 15. A wire tube 17 is fixed on the upper surface of the slider 16. The wire tube 17 includes a bottom shell 171 and a top cover 172 hinged to the upper surface of the bottom shell 171. Magnetic buckles 18 are provided at the opening ends of the bottom shell 171 and the top cover 172. A handle 19 is also fixed on the upper surface of the top cover 172.

[0028] The conduit 17 is slidably connected to the guide rail 15 at the bottom of the support frame 11 via sliders 16. Two sets of guide rails 15 are arranged in parallel, with corresponding sliders 16 on each set of guide rails 15. The same conduit 17 is fixed on two corresponding sliders 16 and can be freely adjusted along the guide rails 15. The conduit 17 consists of a bottom shell 171 and a top cover 172, which are connected by a hinge. The open end is provided with a magnetic buckle 18, which is fixed by magnetic force when closed to prevent the wire harness from falling off. Each end of the top cover 172 is provided with a handle 19 for easy opening and closing. The ports at both ends of the conduit 17 are used for wire harness insertion and exit. The spacing of multiple conduits 17 can be adjusted according to the number and direction of the wire harness to achieve classification and organization.

[0029] Furthermore, the movable wheel assembly 12 includes omnidirectional wheels 121 and directional wheels 122. The pusher 14 is disposed on the side of the device near the directional wheels 122. When the device is pushed, the directional wheels 122 ensure the stability of linear movement, while the omnidirectional wheels 121 facilitate steering, making it suitable for multi-area movement needs within the test center.

[0030] Furthermore, two sets of guide rails 15 are arranged in parallel, and two sets of guide rails 15 are provided with corresponding number and specifications of sliders 16. The same wire guide tube 17 is fixed on the two corresponding sliders 16, which allows the wire guide tube 17 to move freely and conveniently move to the corresponding interface position of the wire harness testing equipment.

[0031] Furthermore, each conduit 17 has ports at both ends, and a handle 19 is provided on the upper surface of the top cover 172 at both ends of the conduit 17. The ports at both ends of the conduit 17 are used for wire harnesses to pass through and out. The spacing of multiple conduits 17 can be adjusted according to the number and direction of the wire harnesses to achieve classification and organization. The handles 19 at both ends make it easy for people to open the conduit 17 from both sides.

[0032] Furthermore, the wire end clamping assembly 2 includes a base plate 21 fixed to the upper surface of the slider 16. A clamping member 1 22 and a clamping member 23 are rotatably connected to the upper surface of the base plate 21. The clamping member 1 22 and the clamping member 23 have different specifications. Two spring rods 24 are also hinged to the upper surface of the base plate 21, and the telescopic ends of the two spring rods 24 are respectively hinged to the opposite sides of the clamping member 1 22 and the clamping member 23.

[0033] The clamping components include clamping part one 22 and clamping part two 23, both of which are rotatably connected to the base plate 21 (the base plate 21 is fixed on the slider 16). The two have different specifications to accommodate wire harness ends of different thicknesses. In the natural state, the elastic force of the spring rod 24 keeps the clamping components in a closed clamping state (there are notches at the ends of clamping part one 22 and clamping part two 23, so they are not completely closed, and both ends are chamfered, so the wire harness ends can be easily pressed in by external force when they are fixed). When the clamping components are pulled outward, the spring rod 24 stretches and stores force, and automatically resets after being released, realizing rapid clamping of the wire harness ends.

[0034] Furthermore, both clamping surfaces of clamping component 1 22 and clamping component 23 are provided with universal balls 25, and the inner wall of the cable conduit 17 is also provided with universal balls. When clamping, the universal balls 25 contact the surface of the cable harness, reducing wear when the cable harness is pulled, and adapting to the multi-angle bending requirements of the cable harness.

[0035] The specific working principle of this utility model is as follows: When using this device, the tooling is pushed to the test station by the pusher 14, and adjusted to a suitable position by the movable wheel set 12. Then, the wire harness is tidied up, the magnetic buckle 18 of the wire tube 17 is opened, and the wire harness to be tested is passed through the port of the wire tube 17. The position of the wire tube 17 on the guide rail 15 is adjusted according to the test requirements. The top cover 172 is closed to fix the wire harness and prevent the wire harness from getting tangled. Then, the wire end is fixed, and the clamping member of the wire end clamping component 2 is moved to put the two ends of the wire harness into the clamping member of the corresponding specification. After releasing, the spring rod 24 drives the clamping member to clamp the wire end, and the universal ball 25 protects the surface of the wire harness from damage.

[0036] After completing the above steps, perform the test operation. Take the tool from the placement platform 13 and perform wire harness testing on the placement platform 13 or the test area. During the test, the wire harness direction can be changed by adjusting the position of the threading tube 17. Organize the tool using the hook 111 and the placement platform 13. After the test is completed, release the clamping parts to take out the wire harness, return the tool to its original position, and push the fixture to the storage area. This device, through its movable structure, adjustable threading tube 17, and multi-functional clamping components, solves the problems of messy wire harnesses, inconvenient movement, and troublesome wire end fixing in the test center, thus improving the efficiency and safety of wire harness testing.

[0037] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
