Description

Technical Field

[0001] This utility model relates to the field of cables, and in particular to a low-noise medical electronic wire harness. Background Technology

[0002] With the rapid development of modern medicine, medical electronic devices have increasingly higher requirements for image and information feedback. However, traditional medical electronic harnesses may generate electrostatic discharge or charging effects under vibration or electromagnetic interference, leading to charge accumulation or noise signals, interfering with the measured signal and reducing image clarity. Utility Model Content

[0003] This invention provides a low-noise medical electronic wire harness, the purpose of which is to reduce the problem of electrical noise signals generated by the electronic wire harness during use.

[0004] To achieve the above objectives, embodiments of this utility model provide a low-noise medical electronic wire harness, comprising:

[0005] The cable core includes multiple cable pairs and filler cotton threads. The multiple filler cotton threads fill the gaps formed by the multiple cable pairs. The cable core is also wrapped with a wrapping tape layer, a main shielding layer, a waterproof layer and an outer protective layer. The wrapping tape layer, the main shielding layer, the waterproof layer and the outer protective layer are arranged layer by layer from the inside to the outside.

[0006] The cable pair includes a drain wire and a twisted pair of wire cores, and a shielding layer is provided outside the wire cores and the drain wire;

[0007] The core includes a conductor, and an insulation layer and a semi-conductive shielding layer are provided layer by layer from the inside to the outside of the conductor.

[0008] Preferably, the wrapping layer is formed by winding polyester wrapping tape.

[0009] Preferably, the overall shielding layer is made of tin-plated soft copper wire woven outside the wrapping layer.

[0010] Preferably, the waterproof layer is formed by wrapping a water-blocking material around the overall shielding layer.

[0011] Preferably, the outer protective layer is formed by extrusion of chlorosulfonated polyethylene rubber.

[0012] Preferably, the shielding layer is an aluminum foil shielding layer.

[0013] Preferably, the insulating layer is natural rubber, and the insulating layer is extruded over the conductor.

[0014] Preferably, the conductor is type 5 stranded tin-plated copper.

[0015] Preferably, the semiconductive shielding layer is made of a semiconductive rubber material and is extruded outside the insulating layer.

[0016] The above-mentioned solution of this utility model has the following beneficial effects:

[0017] This application adds a semi-conductive shielding layer between the insulation layer and the shielding layer. The semi-conductive shielding layer has the dual characteristics of a conductor and an insulator, which can quickly shield the charge generated by the vibration of the total shielding layer or external interference to the outside of the wire core through the shielding layer. This effectively avoids the accumulation of charge between the shielding layer and the insulation layer, reduces the impact of charge on the measured signal, and thus ensures the clarity of the image.

[0018] The waterproof layer is formed by wrapping with water-resistant material. The wire harness not only has a water-resistant effect, but it is also easier to bend and use.

[0019] Other features and advantages of this invention will be described in detail in the following detailed description section. Attached Figure Description

[0029] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0030] like Figure 1As shown, an embodiment of this utility model provides a low-noise medical electronic wire harness, including a cable core. The cable core includes multiple cable pairs 100 and multiple filler cotton threads 200, wherein the multiple cable pairs 100 and multiple filler cotton threads 200 are twisted together, such that the multiple filler cotton threads 200 fill the gaps formed by the multiple cable pairs 100. A wrapping layer 300, a total shielding layer 400, a waterproof layer 500, and an outer protective layer 600 are provided outside the cable core (i.e., the filler cotton threads 200 and the cable pairs 100). The wrapping layer 300 is wrapped around the outside of the cable core, and the total shielding layer 400, the waterproof layer 500, and the outer protective layer 600 are arranged sequentially from the inside to the outside. The aforementioned cable pair 100 includes twisted wire cores 120 and drain wires 110. A shielding layer 130 is wrapped around the drain wires 110 and wire cores 120. The aforementioned wire cores 120 include conductors 121. The conductors 121 are provided with insulation layers 122 and semi-conductive shielding layers 123 layer by layer from the inside to the outside.

[0031] In this application, a semi-conductive shielding layer 123 is added, which can shield the charge generated by vibration or external interference from the wire core 120, thereby reducing the impact on the transmission of the measured signal and improving the image clarity.

[0032] Furthermore, the wrapping layer 300 is formed by wrapping polyester tape, and the total shielding layer 400 is woven from tin-plated soft copper wire outside the wrapping layer 300. The shielding layer 130, together with the total shielding layer 400, can further enhance the shielding effect of the cable, reduce electromagnetic interference, and ensure the stability of the transmission of the measured signal.

[0033] Preferably, the waterproof layer 500 is formed by wrapping with water-resistant material, which not only has a water-resistant effect, but also makes the wire harness easier to bend and convenient to use.

[0034] Preferably, the outer protective layer 600 is formed by extrusion of chlorosulfonated polyethylene rubber, which has good mechanical strength and flexibility, as well as oil resistance and wear resistance, thus extending its service life.

[0035] Preferably, the shielding layer 130 is an aluminum foil shielding layer, which is wrapped around the drain wire 110 and the core 120. The insulating layer 122 is natural rubber, which is extruded around the conductor 121. The aforementioned semiconductive shielding layer 123 is made of semiconductive rubber material, which is extruded around the insulating layer 122.

[0036] Preferably, the aforementioned conductor 121 is a type 5 stranded tin-plated copper conductor. The type 5 stranded tin-plated copper conductor has a small wire diameter, which makes the formed wire harness more flexible, and the minimum bending radius can be reduced to twice the wire harness diameter.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
