Abstract

The utility model discloses a data transmission wire, comprising a sheath, and a shielding layer, signal lines and a power line arranged in the sheath. The signal lines are insulating core wires; the power line is an insulating core wire or an enameled wire; the shielding layer wraps the signals lines and the power line; and at least two ground wires are also wrapped in the shielding layer, wherein each ground wire is a copper wire conductor. Thus, the at least two ground wires are arranged separately, and each ground wire is the copper wire conductor, so that under the condition that voltage drop requirement of the data transmission wire is ensured to be satisfied, the diameter of the data transmission wire is effectively decreased, and internal structure of the data transmission line is more compact, appearance smooth and feeling soft, thereby being able to reduce difficulty of a manufacturer in designing and manufacturing, and more suitable for industrial specification.

Description

Data line

Technical field

The utility model relates to the wire rod art, refers in particular to a kind ofly to adopt many copper conductors as the data line of ground wire.

Background technology

At present, competition along with household electrical appliances market, the various countries dealer has released mini electrical home appliances one after another, to cause numerous consumers, for example mini television set, mini computer, mini display, mini PC and multiple portable mini electronic equipment, these electronic products are subjected to youthfully at present to like that the huge market is arranged very much.

these electronic products generally need to carry out transfer of data with data wire, in prior art, data line is generally by two signal line, two power lines, ground wire and parcel signal line, power line, the screen of ground wire and sheath form, power line and signal line are insulation core wire, its weak point is: as reducing the data line external diameter, must reduce its internal power cord, signal line and ground linear diameter, yet, power line in this type of data line, signal line and ground wire are insulation core wire, this kind insulation core wire comprises insulated hull and plain conductor, reducing the insulation core wire diameter need reduce plain conductor diameter and insulated hull thickness or reduce one of them, but, this method that reduces the data line external diameter is difficult to realize satisfying under the prerequisite that pressure drop requires, therefore, reduce the data wire external diameter and become the problem that manufacturer need to face, the difficulty of having brought design and having produced to manufacturer, therefore, should improve.

The utility model content

In view of this, the utility model is for the disappearance of prior art existence, and its main purpose is to provide a kind of data line, and it can effectively solve the available data transmission line and satisfy the problem that under the pressure drop requirement condition, its external diameter of minimizing has difficulties.

For achieving the above object, the utility model adopts following technical scheme:

A kind of data line includes sheath and is arranged at this sheath interior screen, signal line and power line; This signal line is insulation core wire, and this power line is insulation core wire or enamelled wire, and this screen wraps this signal line and power line, also is enclosed with at least two ground wires in this screen, and each ground wire is copper conductors.

As a kind of preferred version, described signal line is two, and this power line is one.

As a kind of preferred version, described ground wire is three.

As a kind of preferred version, data line inside is concentrated or be uniformly distributed in to described three ground wires.

As a kind of preferred version, be folded with aluminium foil layer and mesh grid between the internal face of described screen and sheath, this mesh grid is coated on the outer surface of this aluminium foil layer.

As a kind of preferred version, be provided with filler in the gap between described power line, each signal line and each ground wire.

As a kind of preferred version, described filler is yarn, line or silk class filler.

As a kind of preferred version, described enamelled wire is enamel covered wire.

The utility model compared with prior art has obvious advantage and beneficial effect, particularly, and as shown from the above technical solution:

One, by ground wire is separated at least two settings, and adopt copper conductors as each root ground wire, make in assurance and satisfy under the prerequisite of data line pressure drop requirement, effectively reduce the diameter of data line, and make that the data line internal structure is compacter, outward appearance is round and smooth, sense matter is soft, can reduce difficulty on Design and manufacture to manufacturer, thereby more adapt to the industry specification requirement.

Two, by being provided with filler in the gap between power line, each signal line and each ground wire, utilize filler can effectively strengthen the anti-performance of waving of data line, extend the useful life of data line, for user's use brings convenience.

For more clearly setting forth architectural feature of the present utility model and effect, below in conjunction with accompanying drawing and specific embodiment, the utility model is elaborated.
