Abstract
The invention discloses a low-loss and high-temperature resistant cable, which comprises an inner conductor. An insulating layer, a braided layer, a tin coating and a jacket layer are sequentially coated outside the inner conductor; and a group of longitudinal holes is formed in the insulating layer. The circular holes arranged longitudinally and uniformly are distributed in the insulating layer, and the dielectric constant of air is 1, so that the dielectric constant of the cable is reduced from original 2.1-2.2 to 1.7-1.8, the transmission attenuation of the cable is greatly reduced, and the cable has good transmission performance; and loss of power in equipment is greatly reduced, and the gain performance of an antenna with the same configuration is improved.
Description
Technical field
The invention belongs to field of cables, be specifically related to the high temperature resistant coaxial cable of a kind of minor diameter, ultralow decay.
Background technology
Be used for the miniature diameter coaxial cable in the electronic equipments such as antenna, mobile phone, notebook computer, Medical Devices in the market, it mainly act as the signal transmission.Because of the particularity of use occasion, generally adopt polytetrafluoroethylene (PTFE) and gather these two kinds of insulating material of 4-methylpentene (TPX) with good resistance to elevated temperatures.But when making this cable, the dielectric constant of cable can not be satisfactory, and the value that particularly is difficult to realize DIELECTRIC CONSTANTS is less than 2, especially less than 1.8.And the size of dielectric constant can directly influence the fade performance index of cable, thereby influences the overall transfer performance of equipment.
Summary of the invention
Goal of the invention: the objective of the invention is to deficiency, a kind of Stability Analysis of Structures, low-loss, resistant to elevated temperatures miniature diameter coaxial cable are provided to prior art.
Technical scheme: in order to achieve the above object, the present invention specifically realizes like this: the low-loss high temperature-resistant cable, comprise inner wire, and inner wire is coated with insulating barrier, braid, tin coating and restrictive coating outward successively, has one group of vertical hole in the said insulating barrier.
Wherein, said insulating layer material is polytetrafluoroethylene or gathers the 4-methylpentene.
Wherein, said inner wire is silver-coated copper wire or silver-plated copper twisted wire.
Wherein, said vertical number of perforations can generally be made as 4～10 according to the size adjustment of cable size.
Beneficial effect: the present invention compares with conventional art; In insulating barrier, increased and be furnished with vertically evenly distributed circular hole, because of the dielectric constant of air is 1, the dielectric constant of cable is reduced to 1.7-1.8 by original 2.1-2.2; Greatly reduce the transmission attenuation of product, possess good transmission performance; The same frequency decay reduces more than 20% at least, has significantly reduced the loss of equipment internal power, has increased the gain performance with the configuration antenna.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Shown in accompanying drawing, low-loss high temperature-resistant cable provided by the invention comprises inner wire 1; This inner wire 1 is a silver-coated copper wire; Be coated with insulating barrier 2, braid 3, tin coating 4 and restrictive coating 5 successively outside the inner wire 1, said insulating barrier 2 materials are polytetrafluoroethylene, and have 7 vertical holes 6 in the insulating barrier 2.
Claims (3)
1. the low-loss high temperature-resistant cable is characterized in that, comprises inner wire (1), and inner wire (1) is outer to be coated with insulating barrier (2), braid (3), tin coating (4) and restrictive coating (5) successively, has one group of vertical hole (6) in the said insulating barrier (2).
