Description

Technical Field

[0001] This utility model relates to the field of electrical wiring harness technology, specifically to an electrical wiring harness device that is anti-interference and has an adaptively adjustable layout. Background Technology

[0002] As the core carrier for transmitting power and signals in electrical equipment, the performance of electrical wiring harnesses directly affects the operational stability and signal transmission quality of the equipment. With the development of electrical equipment towards integration, miniaturization, and multi-functionality, the number and types of wiring harnesses are constantly increasing, and the wiring environment is becoming increasingly complex.

[0003] Electrical wiring harnesses are typically used in environments with numerous sources of strong electromagnetic radiation. However, existing wiring harnesses often use a single insulation layer and lack specific anti-interference structures, leading to signal crosstalk between different harnesses or intrusion of external electromagnetic radiation. This can increase the bit error rate of signal transmission and even cause equipment malfunctions. Furthermore, existing wiring harnesses are often connected to the equipment housing using cable ties, clips, or other fixing methods. Once the wiring path is determined, it cannot be flexibly adjusted. If the position of internal components changes or new wiring harnesses are needed, the original fixing structure must be disassembled and rewired, which is cumbersome and can easily damage the wiring harness insulation layer. Utility Model Content

[0004] In view of the problems existing in the current electrical wiring harness, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide an electrical wiring harness device that is anti-interference and can adaptively adjust its layout. This solves the problem that electrical wiring harnesses are often used in environments with a large number of strong electromagnetic radiation sources, and that existing wiring harnesses are mostly wrapped with a single insulation layer and lack a targeted anti-interference structure, which leads to signal crosstalk between different wiring harnesses or the intrusion of external electromagnetic radiation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An electrical wiring harness device with anti-interference and adaptive layout includes a fixed base. Two clamping blocks are slidably disposed on the upper surface of the fixed base, and a wiring harness body is clamped between the two clamping blocks. The wiring harness body includes multiple wire cores. A first shielding layer is disposed on the outer surface of each wire core. A second shielding layer is disposed on the outer surface of the first shielding layer. An outer protective layer is disposed on the outer surface of the second shielding layer. A cavity is opened inside the fixed base, and an adjustment mechanism is disposed inside the cavity. Both clamping blocks are moved through the adjustment mechanism.

[0008] Preferably, the adjustment mechanism includes two first trapezoidal blocks, two T-shaped blocks, a second trapezoidal block, a lead screw, a knob, and sliders. The two first trapezoidal blocks are symmetrically slidably disposed inside the cavity. Each of the two first trapezoidal blocks has a T-shaped groove on its inclined surface. The two T-shaped blocks are slidably disposed inside their respective T-shaped grooves. The second trapezoidal block is fixedly connected between the two T-shaped blocks. The lower surface of the cavity has an internal threaded hole. The lead screw is threaded into the internal threaded hole and rotatably connected to the lower surface of the second trapezoidal block. The knob is fixedly connected to one end of the lead screw. The two sliders are fixedly connected to the upper surfaces of their respective first trapezoidal blocks. One end of each slider penetrates the upper surface of the cavity and is fixedly connected to the lower surface of their respective clamping blocks.

[0009] Preferably, the first shielding layer is made of copper mesh and wrapped around the outer surface of the wire core; the second shielding layer is made of ferrite absorbing material and is bonded to the outer surface of the first shielding layer with a high-temperature adhesive; and the outer protective layer is made of stainless steel wire and polyimide fiber and is woven together on the outer surface of the second shielding layer.

[0010] Preferably, the lower surface of the fixing base has a circular hole that matches the knob, and the surface of the knob has a hexagonal groove.

[0011] Preferably, the lower surface of the fixing base is provided with a mounting groove, and magnets are fixedly connected inside both mounting grooves.

[0012] Preferably, the upper surface of the cavity is symmetrically fixedly connected with two strip holes, and the two sliders are respectively slidably disposed inside the corresponding strip holes.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. This utility model achieves full-band electromagnetic interference protection through a composite structure of a first shielding layer woven with copper mesh and a second shielding layer absorbing ferrite waves. The first shielding layer shields against low-frequency electromagnetic radiation, effectively blocking signal crosstalk between wire harnesses; the second shielding layer absorbs high-frequency radiation, preventing the intrusion of signals by strong external electromagnetic environments. Compared with traditional single-insulation layer wire harnesses, the signal transmission bit error rate is reduced.

[0015] 2. In this utility model, the lead screw drive of the adjustment mechanism, combined with the trapezoidal block transmission, allows the clamping block to adapt to wire harnesses of different specifications without the need to replace the clamps. The fixing seat achieves "instant placement and fixation" through magnetic adsorption, eliminating the need to drill holes and damage the equipment casing. When the position of internal components changes, the wiring path of the wire harness can be quickly adjusted, reducing maintenance costs. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0023] This utility model discloses an electrical wiring harness device that is anti-interference and has an adaptively adjustable layout.

[0024] This utility model provides, for example Figure 1-3 An anti-interference and adaptively adjustable electrical wiring harness device is shown, including a fixed base 1. Two clamping blocks 2 are slidably disposed on the upper surface of the fixed base 1, and a wiring harness body 3 is clamped between the two clamping blocks 2. The wiring harness body 3 includes multiple wire cores 4. A first shielding layer 5 is disposed on the outer surface of each wire core 4. A second shielding layer 6 is disposed on the outer surface of the first shielding layer 5. An outer protective layer 7 is disposed on the outer surface of the second shielding layer 6. A cavity is opened inside the fixed base 1, and an adjustment mechanism is disposed inside the cavity. Both clamping blocks 2 can be moved through the adjustment mechanism.

[0025] like Figure 1 and Figure 3As shown, the adjustment mechanism includes two first trapezoidal blocks 8, two T-shaped blocks 9, a second trapezoidal block 10, a lead screw 11, a knob 12, and a slider 13. The two first trapezoidal blocks 8 are symmetrically slidably disposed inside the cavity. The inclined surfaces of the two first trapezoidal blocks 8 are each provided with a T-shaped groove. The two T-shaped blocks 9 are respectively slidably disposed inside the corresponding T-shaped grooves. The second trapezoidal block 10 is fixedly connected between the two T-shaped blocks 9. The lower surface of the cavity is provided with an internal threaded hole. The lead screw 11 is threaded into the internal threaded hole and rotatably connected to the lower surface of the second trapezoidal block 10. The knob 12 is fixedly connected to one end of the lead screw 11. The two sliders 13 are respectively fixedly connected to the upper surface of the corresponding first trapezoidal blocks 8. One end of each slider 13 penetrates the upper surface of the cavity and is respectively fixedly connected to the lower surface of the corresponding clamping block 2. The upper surface of the cavity is symmetrically fixedly connected with two strip holes. The two sliders 13 are respectively slidably disposed inside the corresponding strip holes.

[0026] Rotating knob 12 causes lead screw 11 to push the second trapezoidal block 10 upward. The second trapezoidal block slides through the T-shaped block 9 in the T-groove of the first trapezoidal block 8 and drives the two first trapezoidal blocks 8 to slide symmetrically outward along the cavity. The first trapezoidal block 8 drives slider 13 to move along the strip hole, and finally pushes clamping block 2 closer to wire harness body 3 to achieve clamping and fixation. Similarly, rotating knob 12 in the opposite direction can facilitate the removal of the wire harness.

[0027] like Figure 1-2 As shown, the first shielding layer 5 is made of copper mesh and wrapped around the outer surface of the wire core 4. The second shielding layer 6 is made of ferrite absorbing material and is bonded to the outer surface of the first shielding layer 5 with high-temperature adhesive. The outer protective layer 7 is made of stainless steel wire and polyimide fiber and is woven together on the outer surface of the second shielding layer 6.

[0028] The first shielding layer 5 is made of copper mesh and wrapped around the outside of the core 4 structure to shield against external low-frequency electromagnetic interference. The second shielding layer 6 is made of ferrite absorbing material and is attached to the outside of the grounding and current-draining layer with high-temperature resistant adhesive to absorb high-frequency electromagnetic interference and effectively suppress the influence of high-frequency radiation on signal transmission. The outer protective layer 7 is made of stainless steel wire and polyimide fiber mixed braid, which has both electromagnetic shielding and mechanical protection functions and can resist external impact and friction to improve the service life of the wire harness.

[0029] like Figure 1 As shown, a circular hole is provided on the lower surface of the fixing base 1, which matches the knob 12. A hexagonal groove is provided on the surface of the knob 12.

[0030] By placing the knob 12 inside the circular hole, the fixing base 1 can block the knob 12 when it is fixed, preventing the knob from turning due to accidental contact. At the same time, the hexagonal groove makes it convenient for workers to turn the knob with an Allen wrench.

[0031] like Figure 1 As shown, the lower surface of the mounting base 1 is provided with mounting grooves, and magnets 14 are fixedly connected inside the two mounting grooves.

[0032] The two magnets 14 on the lower surface of the mounting base 1 can be directly attached to the metal casing or mounting plate of the equipment without drilling or tightening bolts, achieving "place and fix". If the equipment casing is made of non-metallic material, it can also be indirectly fixed by using magnets in conjunction with metal washers, which greatly improves the installation flexibility of the mounting base, especially suitable for scenarios that require frequent adjustment of the wiring harness layout.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
