Abstract
The invention provides a cable for cardiac speculum, comprising a PE insulator, a soft copper wire conductor and a TPU sheathe; the soft copper wire conductor is externally provided with the PE insulator; the soft copper wire conductor is externally wrapped with a conductive shielding layer which is externally wrapped with the TPU sheath; a winding shielding layer is arranged between the TPU sheath and the conductive shielding layer; the internal layer of the conductive shielding layer is filled with a paper tape layer; and a filled layer is arranged at the internal central position of TPU sheath. The invention has the beneficial effects that the adoption of TPU sheath and PE insulator has good environment protection effect; insulation and isolation performances can be improved; and the invention can be widely applied in the aspect of medical cardiac speculum equipment.
Description
Technical field
The present invention relates to electric wire and cable technology field, relate in particular to a kind of cable for cardiac speculum.
Background technology
The present cable that is used for medical heart speculum apparatus aspect generally is made up of conductor, insulating barrier and sheath etc., and this type of cable has certain convenience in the use, but because it exists many deficiencies due to the structure aspect electric property; These unreasonable structures mainly can influence mechanical and physical performance, fire protecting performance and the environment protecting etc. of cable and wire, and exist the too high defective of production cost to a certain extent.Therefore, the improvement of cable and wire different levels structure can help to improve the performance of product, makes it guarantee a good user mode, and then increases the service life.
Summary of the invention
At above defective, the invention provides a kind of rational in infrastructure, environment protecting better, can improve the cable for cardiac speculum of insulation and isolation performance, to overcome many deficiencies of existing like product.
For achieving the above object, the present invention is by the following technical solutions:
A kind of cable for cardiac speculum, comprise PE insulator, annealed copper wire conductor and TPU sheath, the outside of described annealed copper wire conductor is provided with the PE insulator, annealed copper wire conductor outside is wrapped with conductive shielding layer, the outside of described conductive shielding layer is wrapped with the TPU sheath, be provided with the winding screen between described TPU sheath and the conductive shielding layer, the internal layer of described conductive shielding layer is dosed layer of paper, and the inside center position of described TPU sheath is provided with packed layer.
The beneficial effect of cable for cardiac speculum of the present invention is: adopt TPU sheath and PE insulator, make it have good environment protecting; Can improve insulation and isolation performance; Can be widely used in medical heart speculum apparatus aspect.
