Abstract

The utility model discloses a kind of three core USB data line of power line dual shield, mainly comprise plastic wrapper, metallic shield cover, metal wire being surrounded by housing and plastic sheath, two metal wire and fillers being surrounded by plastic sheath.Described plastic wrapper encases metallic shield cover, metallic shield cover encases the metal wire that is surrounded by housing and plastic sheath, two metal wire and fillers being surrounded by plastic sheath, described metallic shield cover forms with metal forming by netted metal wire knitted is complete, described three wires being surrounded by plastic sheath are made up of many one metal wires, of the present utility modelly to be characterised in that: wires outsourcing red plastic cover and a metallic shield net, for the connection of positive supply, the metallic shield net of this wires overlaps with metallic shield and is connected, for connecting ground wire, like this dual shield effect is played to that wires connecting positive supply.Beneficial effect is: the metal wire connected for positive supply has had dual shielding, effectively stops the electromagnetic interference that power line causes.

Description

A kind of three core USB data line of power line dual shield

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 has 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 linear of available data line is generally: have individual metallic shield cover in a plastic wrapper, containing four metal line in metallic shield cover, the plastic sheath of insulation is all surrounded by outside every metal line, wherein two for transmission of signal, color is generally white and green, other two is power line, wherein one red is conveying positive supply, another black is the ground wire of power supply, this data wire is generally four-core data wire, relatively thicker, quality is also soft not, is not very tight to the shielding of power line.

Utility model content

The purpose of this utility model is the deficiency in order to solve above-mentioned technology, a kind of three core USB data line of power line dual shield are proposed, save a metal wire for ground connection and outsourcing plastic sheath, increase the housing of power line, strengthen the shield effectiveness of power line.

The utility model is realized by following technical scheme: a kind of three core USB data line of power line dual shield, mainly comprise plastic wrapper, metallic shield cover, metal wire being surrounded by housing and plastic sheath, two metal wire and fillers being surrounded by plastic sheath.Described plastic wrapper encases metallic shield cover, metallic shield cover encases the metal wire that is surrounded by housing and plastic sheath, two metal wire and fillers being surrounded by plastic sheath, described metallic shield cover forms with metal forming by netted metal wire knitted is complete, described three wires being surrounded by plastic sheath are made up of many one metal wires, of the present utility modelly to be characterised in that: wires outsourcing red plastic cover and a metallic shield net, for the connection of positive supply, the metallic shield net of this wires overlaps with metallic shield and is connected, for the external shielding case of the ground wire and data wire that connect power supply, like this dual shield effect is played to that wires connecting positive supply.

The beneficial effects of the utility model are:

The metal wire connected for positive supply has dual shielding, effectively stops the electromagnetic interference that power line causes.

Accompanying drawing explanation

Fig. 1 is three core USB data line core schematic cross-sections of a kind of power line dual shield of the utility model.

Embodiment

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

As shown in Figure 1, there is shown, a kind of three core USB data line of power line dual shield, mainly comprise plastic wrapper 1, metallic shield cover 2, the metal wire 4, one that one is surrounded by red plastic cover 3.1 outward, the metal wire 3, of metallic shield net 3.2 is surrounded by green plastic cover 4.1 is surrounded by metal wire 5 and the filler 6 of white plastic cover 5.1.

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 and metallic shield net 3.2, one is surrounded by the metal wire 4 that green plastic overlaps 4.1, one is surrounded by metal wire 5 and the filler 6 that white plastic overlaps 5.1, described metallic shield cover 2 forms with metal forming by netted metal wire knitted is complete, described three wires being surrounded by plastic sheath are made up of many one metal wires, of the present utility modelly to be characterised in that: metal wire 3 both bag red plastic cover 3.1 is also surrounded by metallic shield net 3.2, for the connection of positive supply, metallic shield cover 2 is connected with metallic shield net 3.2, and for the external shielding case of the ground wire and data wire for connecting power supply, such metal wire 3 has had dual shield.

Claims

1. three core USB data line of a power line dual shield, mainly comprise plastic wrapper, metallic shield cover, a metal wire being surrounded by housing and plastic sheath, two metal wire and fillers being surrounded by plastic sheath, described plastic wrapper encases metallic shield cover, metallic shield cover encases the metal wire that is surrounded by housing and plastic sheath, two metal wire and fillers being surrounded by plastic sheath, described metallic shield cover forms with metal forming by netted metal wire knitted is complete, described three wires being surrounded by plastic sheath are made up of many one metal wires, of the present utility modelly to be characterised in that: wires outsourcing red plastic cover and a metallic shield net, for the connection of positive supply, the metallic shield net of this wires overlaps with metallic shield and is connected, for the external shielding case of the ground wire and data wire that connect power supply, like this dual shield effect is played to that wires connecting positive supply.
