Technical Field
[0001] This utility model relates to the field of 00 technology, and in particular to a multi-core wire harness for signal transmission. Background Technology
[0002] Multi-core wire harnesses for signal transmission play a crucial role in the signal interaction of electronic devices and the transmission of control commands in industrial systems. They are used to synchronously transmit multiple independent signals, avoiding the messy wiring and signal interference caused by single-cable transmission. They enable the accurate transmission of data and commands between different modules, facilitating the overall coordinated operation of equipment and reducing signal transmission loss and delay. Multi-core wire harnesses for signal transmission are widely used in industrial automated production lines, automotive electronic control systems, medical testing equipment, and communication base stations, meeting the needs of stable transmission of multiple signals in various scenarios.
[0003] When transmitting multiple independent signals synchronously, avoiding the messy wiring and signal interference caused by single-cable transmission, and accurately transmitting data and instructions between different modules, multi-core wire harnesses for signal transmission are required. Existing multi-core wire harnesses for signal transmission are mostly single-layer insulation sheaths and simple braided shielding structures, and the internal wires lack independent isolation and fixing designs. This makes it easy for the wires to rub against each other during assembly and use, causing the insulation layer to break. The shielding layer, due to its simple structure, cannot effectively resist interference from complex electromagnetic environments, and additional protective accessories are needed to compensate for the defects. This will significantly increase production costs. At the same time, damaged insulation layers are prone to signal crosstalk, ultimately leading to reduced product quality and shortened service life. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a multi-core wire harness for signal transmission, aiming to improve the problems caused by structural design defects in wire harnesses in the prior art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a multi-core wire harness for signal transmission, comprising a transmission line, a first arc-shaped ring slidably connected to the outer wall of the transmission line, a plurality of mounting posts fixedly connected to the outer wall of the first arc-shaped ring, a rotating shaft rotatably connected to the inner wall of each of the plurality of mounting posts, a connecting post rotatably connected to the outer wall of the rotating shaft, a second arc-shaped ring fixedly connected to the outer wall of the connecting post, a buckle fixedly connected to the outer wall of the second arc-shaped ring, a slot formed on the inner wall of the first arc-shaped ring, a sliding pin fixedly connected to the outer wall of the first arc-shaped ring, a mounting ring engaged with the outer wall of the sliding pin, and an unlocking mechanism slidably connected to the outer wall of the mounting ring, the unlocking mechanism being used for quickly disassembling the connection of the multiple wire harnesses.
[0006] As a further description of the above technical solution: The unlocking mechanism includes a locking ring, the inner wall of which is slidably connected to the outer wall of the mounting ring, a sliding post slidably connected to the inner wall of the locking ring, a first spring fixedly connected to the rear end of the sliding post, a pressing piece fixedly connected to the front end of the sliding post, a sliding groove provided on the inner wall of the sliding post, a ball slidably connected to the inner wall of the sliding groove, and multiple locking grooves provided on the inner wall of the mounting ring.
[0007] As a further description of the above technical solution: A nylon rod is slidably connected to the inner wall of the mounting ring, and an unlocking port is provided on the inner wall of the first arc ring.
[0008] As a further description of the above technical solution: The outer wall of the nylon rod is fixedly connected to a protective sleeve, and the outer wall of the protective sleeve is slidably connected to multiple transmission lines.
[0009] As a further description of the above technical solution: Multiple aluminum foils are slidably connected between adjacent transmission lines, and the outer wall of the aluminum foil is slidably connected to the outer wall of the protective sleeve.
[0010] As a further description of the above technical solution: Multiple transmission lines have shielding films slidably connected to their outer walls, and flexible tubes are slidably connected to the outer walls of the shielding films.
[0011] As a further description of the above technical solution: The front end of the transmission line is fixedly connected to a connector, and the inner wall of the connector has a connection groove.
[0012] As a further description of the above technical solution: The flexible tube has a slidable braided mesh on its outer wall, and a marking sticker is fixedly connected to the outer wall of the braided mesh.
[0013] This utility model has the following beneficial effects: 1. In this utility model, when the multi-core wire harness is in operation, the first arc-shaped ring is slid along the outer wall of the transmission line to a suitable position, which can flexibly adapt to different wiring requirements and avoid fixed position restrictions. Then, the connecting column is rotated around the pivot of the inner wall of the mounting column, which drives the second arc-shaped ring to adjust the angle, so that the buckle on the outer wall of the second arc-shaped ring is aligned and engaged with the slot on the inner wall of the first arc-shaped ring. The double fixing structure improves the stability of a single transmission line and prevents loosening. When multiple wire harnesses need to be integrated, the sliding pins on the outer walls of each first arc-shaped ring are engaged with the same mounting ring to achieve a neat arrangement of multiple wire harnesses, reduce wire tangling, reduce the risk of signal crosstalk, ensure orderly signal transmission, and simplify the later maintenance process, which can improve product quality and increase service life.
[0014] 2. In the initial state of this utility model, the inner wall of the locking ring is tightly fitted with the outer wall of the mounting ring. The sliding column is pushed by the elastic force of the first spring at the rear end, causing the front pressing piece to extend outward. At the same time, the ball in the sliding groove of the inner wall of the sliding column is squeezed and locked into the locking groove of the inner wall of the mounting ring, forming a double lock to prevent the wire harness from loosening due to vibration. When unlocking is required, pressing the pressing piece causes the sliding column to compress the first spring and move backward. The ball disengages from the locking groove and returns to the sliding groove. At this time, pushing the locking ring can remove it along the outer wall of the mounting ring. The operation only requires one pressing step, which greatly improves the efficiency of disassembly and assembly. Moreover, the spring force is stable, ensuring long-term reliability.
