Abstract

The utility model discloses a micro double-core, double-shielding and double-sheath flexible cable which comprises two conductors. An insulating layer is wrapped outside each conductor; a individual shielding layer is braided outside the insulating layer; an inner sheath is arranged outside the individual shielding layer; a film layer is wrapped reinforced cores after the cores are filled and twisted in pair; a collective shielding layer is arranged outside the film layer; and a sheath is extruded outside the collective shielding layer. Each conductor adopts a single high temperature resistant silver coated copper wire with fine diameter; the insulation is wrapped by selecting a high temperature resistant F4 film to improve the softness of the cable; the individual shield adopts a silver coated copper wire with high braided density, and the collective shield is also added simultaneously, thereby improving the anti-interference ability of the cable; the reinforced core filled not only enables that the tensile force of the cable is improved, but also ensures that the outer appearance of the cable is round and smooth and the surface is artistic, so as to eliminate the phenomenon like out-of-round outer appearance and exposed marks; and a new cable species is increased and the selection scope of a user is enlarged.

Description

The two sheath flexible cables of microminiature twin-core double shield

Technical field

The utility model relates to the two sheath flexible cables of a kind of twin-core double shield.

Background technology

Existing twin cable, often pliability is bad, and the pull-off force that bears is not enough.And in the new medical transducer of the high reliability in the general frequent portable medical instrument and equipment, need that antijamming capability is strong, pull-off force is big, lay the cable that the space is little, pliability is good, adopts general two core cable to be difficult to reach requirement.

Summary of the invention

The purpose of this utility model is, provides a kind of antijamming capability strong, and pull-off force is big, volume is little,, film lapped insulation microminiature twin-core double shield double sheathed cable that pliability is good.

The technical solution of the utility model is as follows:

The two sheath flexible cables of microminiature twin-core double shield is characterized in that: include 2 conductors, and the every outer lapped insulation layer of conductor, insulating barrier weaves sub-shield outward, and sub-shield has inner sheath outward; Wrapped thin layer behind the filling strengthening core pair twist, thin layer has total screen outward, and total screen is extruded with sheath outward.

The two sheath flexible cables of described microminiature twin-core double shield, it is characterized in that: described conductor material is 2 * 0.35mm ²The silver-plated copper core; Described insulating layer material is that the F4 film is wrapped; Described sub-shield is the silver-coated copper wire braid, and count is more than 90%; Described inner sheath material is that the F4 film is wrapped; Described strengthening core is a nylon rope; Described total screen is the tinned wird braid, and count is more than 85%; Described jacket material is soft butyronitrile PVC compound.

The utility model has the advantages that: conductor adopts the very thin high temperature resistant silver-coated copper wire of single diameter, the wrapped pliability that improves cable of high temperature resistant F4 film is selected in insulation for use, adopted the high silver-coated copper wire of count to divide shielding, increased simultaneously total shielding again, improve the antijamming capability of cable like this, the strengthening core of filling not only makes the cable pull-off force improve, also make simultaneously cable appearance rounding, smooth, surface aesthetic, rounding, lines such as do not expose at phenomenon to have stopped outward appearance, increase the new varieties of cable again, enlarged user's range of choice.
