Abstract
The utility model relates to an induction anti-noise cable used in the medical industry and solves the technical problem that the cable for medical use should have the advantages of good signal transmission quality and product flexibility performance. The technical scheme is that the induction anti-noise cable for medical use comprises an inner conductor, in insulation layer, a shield layer and a protection sleeve layer which are sequentially and coaxially wrapped from the inside to the outside. The induction anti-noise cable for medical use is characterized in that the insulation layer comprises an inner insulation layer made of poly ethylene (PE) materials and a semi-conductive elastic polyvinyl chloride (PVC) material layer wrapped outside the inner insulation layer. The protection sleeve layer adopts PVC materials.
Description
Technical field
The utility model relates to a kind of coaxial cable, especially the sensing anti-noise ripple cable of medical industry use.
Background technology
Along with the continuous development of the communication technology, coaxial cable has been widely used in fields such as broadcasting, TV, radar, navigation, computer and instrument.Common coaxial cable comprises inner wire, insulating barrier, screen, the restrictive coating of coaxial coating from inside to outside; This type of coaxial cable is used for conventional look the transmission of screen signal and satisfying instructions for use; But for the Medical Devices that have high definition to require, still be weak; Especially dielectric constant and the mechanical sense of cable under the high frequency condition voltage of making an uproar remains at certain distance, has room for improvement.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of improvement of medical cable is provided, and this medical cable should have the characteristics that signal transmission quality is good and the product flexility is good.
Technical scheme below the utility model has adopted:
Medical sensing anti-noise ripple cable comprises from inside to outside inner wire, insulating barrier, screen and the restrictive coating of coaxial coating successively; It is characterized in that described insulating barrier adopts the inner insulating layer of PE material and is coated on the outside semiconductive elasticity PVC material layer of inner insulating layer.
Said restrictive coating adopts the PVC material.
The beneficial effect of the utility model is: owing to adopted under the high frequency condition dielectric constant lower and keep stable dielectric material PE and semiconductive elasticity PVC combination of materials formation insulating barrier; The mechanical sense of cable is made an uproar voltage can be littler more than 75% than the radio frequency coaxial-cable of existing same specification; Shielding attenuation reaches-35dB; And can obviously reduce clutter and the ghost image that produces in the transmission course, make image and waveform more clear accurately, and product have better pliability.
Description of drawings
Fig. 1 is the main TV structure sketch map of the utility model.
Embodiment
Below in conjunction with Figure of description, the utility model is described further.
Medical sensing anti-noise ripple cable comprises from inside to outside inner wire 1, insulating barrier, screen 3 and the restrictive coating 4 of coaxial coating successively; These are the conventional structure of cable.
The improvement of the utility model is to change described insulating barrier into inside and outside coat two-layer, and this is two-layer to be respectively to adopt the inner insulating layer 2 of PE material and be coated on the outside semiconductive elasticity PVC material layer 5 of internal layer.And, the radial dimension of this materials at two layers after the coating (inner insulating layer and semiconductive elasticity PVC material layer), general identical with the radial dimension of original insulating barrier, constant with the radial dimension that keeps original cable.
Said restrictive coating preferably adopts the PVC material.
The equal buyable of above all material obtains.
The utility model meets following technical indicator through test:
(1) characteristic impedance 75 ± 3.5;
(2) the mechanical sense voltage≤5mV that makes an uproar;
Standing-wave ratio (VSWR) in the 3.0GHz frequency range, standing wave index≤1.12;
(3) speed ratio 75%.
Claims (2)
1. medical sensing anti-noise ripple cable comprises from inside to outside inner wire (1), insulating barrier, screen (3) and the restrictive coating (4) of coaxial coating successively; It is characterized in that described insulating barrier adopts the inner insulating layer (2) of PE material and is coated on the outside semiconductive elasticity PVC material layer (5) of inner insulating layer.
2. medical sensing anti-noise ripple cable according to claim 1 is characterized in that said restrictive coating (4) adopts the PVC material.
