Description

Technical Field

[0001] This utility model relates to the field of electronic wire harness technology, specifically an anti-interference shielded electronic wire harness. Background Art

[0002] An electronic wire harness is a bridge that connects two or more isolated electronic circuits, enabling current to flow and allowing various electronic components to perform their functions. Some wire harnesses require the installation of magnetic rings to suppress high-frequency interference signals.

[0003] For example, CN212342318U discloses an anti-interference shielded electronic wire harness structure, relating to the field of electronic wire harness technology. It includes a wire harness body, with the outer surfaces of the wire cores collectively wrapped with fluororubber heat-shrink tubing. A reinforcing layer is fixedly installed on the outer surface of the fluororubber heat-shrink tubing. An outer shielding sleeve is fixedly wrapped around the outer surface of the reinforcing layer. A waterproof layer is wrapped around the outer surface of the outer shielding sleeve. An outer sheath is wrapped around the outer surface of the waterproof layer. The left side of the wire cores is fixedly connected to a plug-in terminal. A sealing gasket is fixedly installed on the right side of the plug-in terminal. A housing is fixedly installed on the outer surfaces of the plug-in terminal and the sealing gasket. A connecting cylinder is fixedly installed on the right side of the housing. This invention improves the anti-interference and shielding performance of the electronic wire harness, meeting usage requirements. It also enhances the waterproofness of the wire harness body and plug-in terminals, giving the electronic wire harness strong tensile strength and making it less prone to tearing damage.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that the aforementioned device relies on the shielding layer to improve the anti-interference and shielding capabilities of the electronic wire harness. However, the lack of electromagnetic interference suppression function at the connection point of the electronic wire harness makes the signal line at the connection point more susceptible to external electromagnetic interference, leading to a decline in signal quality and potentially causing communication failures or data transmission errors, thereby causing system performance instability or failure.

[0005] Therefore, an anti-interference shielded electronic wire harness is proposed to address the above problems. Utility Model Content

[0008] Preferably, a limiting plate is threadedly connected to the front of the fixed shell, and a clamping block is fixedly installed on the back of the limiting plate.

[0009] Preferably, an outer shielding sleeve is fixedly installed inside the protective sleeve, and an inner shielding sleeve is fixedly installed inside the outer shielding sleeve.

[0010] Preferably, the inner shielding sleeve is provided with an electronic wire harness main line, and multiple partitions are fixedly installed on the surface of the inner shielding sleeve.

[0015] 2. This utility model achieves the function of limiting the magnetic ring through the structural design of the limiting plate and the clamping block, and through the mutual cooperation between the structures.

[0027] The front of the fixed shell 5 is threadedly connected to a limiting plate 8, and a clamping block 9 is fixedly installed on the back of the limiting plate 8.

[0028] Reference Figure 3 and Figure 5 Through the structural design of the limiting plate 8 and the clamping block 9, and through the cooperation between the structures, the function of limiting the magnetic ring 7 is realized, thereby ensuring that the position and direction of the magnetic ring 7 are relatively fixed, thus improving the stability of the wire harness system.

[0029] An outer shielding sleeve 10 is fixedly installed inside the protective sleeve 1, and an inner shielding sleeve 11 is fixedly installed inside the outer shielding sleeve 10.

[0030] Reference Figure 2 and Figure 4 By setting the outer shielding sleeve 10 and the inner shielding sleeve 11, and through their mutual cooperation, the function of double shielding protection is achieved.

The partition 13 separates the electronic wire harnesses for management, preventing mutual interference between the electronic wire harness sub-wires 14. The clamping pad 6 holds the magnetic ring 7, which absorbs and suppresses electromagnetic interference signals. The limiting plate 8 prevents the magnetic ring 7 from detaching from the fixed shell 5. The pressing block 9 further presses the magnetic ring 7 to prevent it from shaking during operation.
