Description

A kind of extremely thin coaxial wire

Technical field

The utility model relates to a kind of coaxial line, especially relates to a kind of extremely thin coaxial wire.

Background technology

At present, in notebook computer or other 3C electronic product, be used for connecting motherboard and LCD and have two kinds basically in the mode of transmission of electric signals, a kind of is the electronics line, and another kind is a soft board, though the electronics line is more cheap, but along with product requirement more and more under close, light, thin, short, little development trend, the use of electronics line is limited to, and the cost of soft board is higher, and is provided with integrated circuit in the soft board, but flexility is relatively poor, and signal transmission power is not good.

The utility model content

The technical problem that the utility model mainly solves provides the extremely thin coaxial wire that but a kind of flexility is strong and anti-electromagnetic interference capability is strong.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of extremely thin coaxial wire is provided, comprise cored wire conductor, be coated on the outer insulator of described cored wire conductor and be coated on the outer shielding conductor layer of described insulator, described cored wire conductor is twisted into or is twisted into by seven heart yearns, the external diameter of the cored wire conductor that is twisted into or is twisted into is below 0.4mm, and described insulator is tetrafluoroethene-perfluoroalkyl ethylene oxy copolymer p FA, ethene-four oxygen ethene ETFE or crosslinked polyethylene XLPE.

Wherein, described shielding conductor layer is coated with an exodermis.

Wherein, described exodermis is tetrafluoroethene-perfluoroalkyl ethylene oxy copolymer p FA, ethene-four oxygen ethene ETFE, polyvinylchloride, cross-linked polrvinyl chloride PVC or polythene PE.

Wherein, the external diameter of described extremely thin coaxial wire is less than 0.8mm.

Wherein, described heart yearn is zinc-plated alloy copper wire, tinned copper wire, silver-plated alloy copper wire or silver-gilt copper wire.

Wherein, described shielding conductor layer is zinc-plated alloy copper wire, tinned copper wire, silver-plated alloy copper wire or silver-gilt copper wire.

Wherein, be provided with a mask tape between described shielding conductor layer and the described exodermis.

Wherein, described mask tape is copper or aluminium foil strip.

The beneficial effects of the utility model are: but be different from the situation that influences the signal transmission when prior art soft board flexility is destroyed or force to yield a little less than, the utility model extremely thin coaxial wire comprises cored wire conductor, be coated on the outer insulator of cored wire conductor and be coated on the outer shielding conductor layer of insulator, described cored wire conductor is twisted into or is twisted into by seven heart yearns, the external diameter of the cored wire conductor that is twisted into or is twisted into is below 0.4mm, the utility model extremely thin coaxial wire external diameter is little, but flexility is strong, anti-electromagnetic interference capability is strong, stable signal transmission, and be easier to go deisgn product according to the functional requirement of every electronic product.
