Description

A kind of USB data line of three cores

Technical field

The utility model relates to a kind of data wire and manufactures field.

Background technology

The digital appliances such as computer, mobile phone is very universal, and in order to mutual transmitting digital signals, its technological means has wireless and wired, and wireless transmission is Bluetooth technology, and what cable technology adopted now in a large number is data wire, and data wire security performance is good, simple to operate.The primary structure of available data line is generally: have individual metallic shield cover in a plastic wrapper, containing four wires in metallic shield cover, all be surrounded by the plastic sheath of insulation outside every metal line, wherein two for transmission of signal, and color is generally white and green, other two is power line, wherein one red is conveying positive supply, and another black is the ground wire of power supply, and this data wire is generally four-core data wire, relatively thicker, quality is also soft not.

Utility model content

The purpose of this utility model is the deficiency in order to solve above-mentioned technology, proposes a kind of USB data line of three cores, can save a wires outsourcing plastic sheath, reduces production cost.

The utility model is realized by following technical scheme: a kind of USB data line of three cores, mainly comprise plastic wrapper, metallic shield cover, three metal wires being surrounded by plastic sheath, a naked metal wire and filler, described plastic wrapper encases metallic shield cover, metallic shield cover encases the metal wire that three are surrounded by plastic sheath, a naked metal wire and filler, described metallic shield cover forms with metal forming by netted metal wire knitted is complete, the described metal wire being surrounded by shades of colour plastic sheath and a naked metal wire are made up of many one metal wires, of the present utility modelly to be characterised in that, the described one naked metal wire for earth connection not bag plastic sheath, and to overlap with metallic shield and be connected, play shielding action.

The beneficial effects of the utility model are:

Plastic sheath prior art being used for the metal wire outsourcing of that root ground connection has been economized, and has saved material and processing cost, data wire external diameter can have been reduced, quality deliquescing.

Accompanying drawing explanation

Fig. 1 is the USB data line schematic cross-section of a kind of three cores of the utility model.

Embodiment

Below in conjunction with accompanying drawing 1 and an embodiment, the utility model is described in further detail:

As Fig. 1, shown in, a kind of USB data line of three cores, mainly comprise plastic wrapper 1, metallic shield cover 2, three metal wires being surrounded by plastic sheath, a naked metal wire 6 and filler 7, described plastic wrapper 1 encases metallic shield cover 2, metallic shield cover 2 encases the metal wire 3 that is surrounded by red plastic cover 3.1, one is surrounded by the metal wire 4 that green plastic overlaps 4.1, metal wire 5 and a naked metal wire 6 and a filler 7 being surrounded by white plastic cover 5.1, described metallic shield cover 2 forms with metal forming by netted metal wire knitted is complete, the metal wire of three described bag shades of colour plastics and naked metal wire 6 are made up of many one metal wires.Of the present utility modelly be characterised in that, described one naked metal wire 6 and metallic shield are overlapped 2 and are connected, and for earth connection, play shielding action.

Claims (1)
