Description
Technical Field
[0001] This utility model relates to the field of power harness technology, and in particular to an anti-interference power harness. Background Technology
[0002] A power harness is a type of wiring harness specifically designed for transmitting electrical power. It plays a crucial role in various electronic devices and systems. Power harnesses are widely used in automobiles to connect batteries, generators, starter motors, and other equipment. They are also suitable for household appliances such as washing machines, refrigerators, and air conditioners, as well as electronic and industrial equipment.
[0003] The power harness body is generally composed of signal conductor wires and a harness insulation jacket, wherein an inner insulation jacket is also provided on the outer wall of the signal conductor wires.
[0004] Currently, existing power harness bodies are susceptible to external electromagnetic interference during use, which can affect the normal signal transmission of the signal conductors within the power harness body and significantly reduce the shielding interference immunity of the signal conductors within the power harness body.
[0005] Moreover, in existing power harnesses, each signal conductor wire is prone to shaking and rubbing against each other, which can cause wear and tear on the outer walls of the signal conductor wires after prolonged use.
[0006] In addition, existing power harnesses are susceptible to puncture damage from external sharp objects, which greatly reduces their resistance to external punctures. Utility Model Content
[0007] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing an anti-interference power harness.
[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] The outer wall of the signal conductor is provided with an anti-interference inner sheath, and an internal anti-wear sleeve is provided at the end of the anti-interference inner sheath away from the signal conductor.
[0011] The elastic wear-resistant plate is provided with a second positioning slot, and the wear-resistant main outer sleeve is provided with a first positioning slot.
[0012] Furthermore, the anti-interference outer layer is disposed on the inner wall surface of the puncture-resistant outer layer, and the anti-interference inner layer is uniformly disposed along the outer wall surface of the signal conductor line.
[0013] Furthermore, both the anti-interference outer layer and the anti-interference inner layer are carbon nanofilm structure layers.
[0014] Furthermore, the central stabilizing post is located at the center of the power harness body, and there are four stabilizing partitions arranged in a circle. The two ends of the stabilizing partitions are respectively fixed to the central stabilizing post and the wear-resistant main jacket.
[0015] Furthermore, the elastic wear-resistant plate is a long strip-shaped structure and is symmetrically arranged on both ends of the stable partition. The elastic wear-resistant plate is made of elastic vulcanized rubber, which has excellent elastic buffering and wear-resistant properties, and is soft and tough. When the signal conductor line is further separated, a certain buffering effect is achieved.
[0016] Furthermore, both the first and second positioning slots are arc-shaped inner grooves. The outer wall of the inner wear-resistant sleeve is engaged with the first and second positioning slots respectively. The arc-shaped inner groove structure enables each signal conductor line to be separated and stably engaged in the first and second positioning slots.

[0020] 2. This utility model achieves the separation and stable engagement of each signal conductor wire in the first and second positioning slots by setting a central stabilizing column with a stabilizing partition inside the power harness body, setting an elastic anti-wear plate with a second positioning slot on the stabilizing partition, and then setting an anti-wear main and outer sleeve structure with a first positioning slot on the power harness body. This avoids the phenomenon of easy shaking and friction between each signal conductor wire, and prevents wear between the outer walls of the signal conductor wires after long-term use.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Reference Figure 1-4 An anti-interference power harness includes a power harness body 1, which is composed of a harness insulating jacket 2 and a signal conductor wire 5. A central stabilizing post 6 is provided in the inner cavity of the harness insulating jacket 2. A stabilizing partition 61 is provided on the central stabilizing post 6. An elastic anti-wear plate 7 is provided on the stabilizing partition 61. A puncture-resistant outer layer 3 is provided inside the power harness body 1. An anti-interference jacket layer 31 is provided at the end of the anti-puncture outer layer 3 away from the harness insulating jacket 2. An anti-wear main jacket 4 is provided at the end of the anti-interference jacket layer 31 away from the harness insulating jacket 2.

[0030] The elastic wear-resistant plate 7 has a second positioning slot 71, and the wear-resistant main jacket 4 has a first positioning slot 41. The power harness body 1 is a commonly used power harness, which is existing technology. Some existing structures are not marked and need not be described in detail.
[0031] Both the outer anti-wear sleeve 4 and the inner anti-wear sleeve 52 are made of elastic vulcanized rubber, and the body is soft, tough, wear-resistant and durable.
[0032] An anti-interference outer layer 31 is disposed on the inner wall surface of the puncture-resistant outer layer 3, and an anti-interference inner layer 51 is uniformly disposed along the outer wall surface of the signal conductor line 5, thereby improving the anti-shielding interference of the signal conductor line 5 in the power harness body 1 to the outside.
[0033] Both the anti-interference outer layer 31 and the anti-interference inner layer 51 are carbon nanofilm structure layers. The carbon nanofilm structure layer has excellent shielding and electromagnetic resistance, which can isolate external electromagnetic interference, and the body has softness and toughness.
[0034] The central stabilizer 6 is located at the center of the power harness body 1. There are four stabilizing partitions 61 arranged in a circle. The two ends of the stabilizing partitions 61 are fixed to the central stabilizer 6 and the wear-resistant main jacket 4, respectively. Both the central stabilizer 6 and the stabilizing partitions 61 are made of nylon and have strong toughness, thus achieving a stable separation effect.
[0035] The elastic wear-resistant plate 7 is a long strip-shaped structure and is symmetrically arranged on both sides of the stable partition 61. The elastic wear-resistant plate 7 is made of elastic vulcanized rubber. Elastic vulcanized rubber has excellent elastic buffering and wear-resistant properties, and its body is soft, tough, wear-resistant and durable. When the signal conductor line 5 is further separated, a certain buffering effect is achieved.
[0036] The first positioning slot 41 and the second positioning slot 71 are both arc-shaped inner grooves. The outer wall of the inner wear-resistant sleeve 52 is respectively engaged with the first positioning slot 41 and the second positioning slot 71. The arc-shaped inner groove structure realizes that each signal conductor line 5 is separated and stably engaged in the first positioning slot 41 and the second positioning slot 71.
[0037] The puncture-resistant outer layer 3 is uniformly arranged along the inner wall of the wire harness insulation jacket 2. The puncture-resistant outer layer 3 is made of CR neoprene rubber, which has excellent puncture resistance, is soft and tough, and also has good chemical corrosion resistance and oil resistance.
[0038] Working principle: By setting an anti-interference outer layer 31 structure on the power harness body 1 and an anti-interference inner layer 51 structure on the outer wall of the signal conductor line 5, the overall anti-shielding interference resistance of the signal conductor line 5 in the power harness body 1 is improved.
[0039] Furthermore, by setting a central stabilizing column 6 with a stabilizing partition 61 inside the power harness body 1, and setting an elastic anti-wear plate 7 with a second positioning slot 71 on the stabilizing partition 61, and then setting an anti-wear main jacket 4 structure with a first positioning slot 41 on the power harness body 1, each signal conductor wire 5 is separated and stably locked in the first positioning slot 41 and the second positioning slot 71, avoiding the phenomenon of easy shaking and friction between each signal conductor wire 5, and preventing wear between the outer walls of the signal conductor wire 5 during long-term use.
[0040] In addition, during use, if the power harness body 1 is punctured by an external sharp object, the overall puncture resistance is improved by setting an anti-puncture outer layer 3 structure on the power harness body 1.
