Description
Technical field
The utility model belongs to technical field of electric connectors, is specifically related to the USB connector high-frequency signal transmission wire of a kind of tin-coated copper plated aluminium magnesium shielding.
Background technology
Aforesaid USB (English full name is: Universal Serial Bus, and Chinese is: USB) is an external bus standard, for connection and the communication of specification computer and external equipment, is the interface being applied to PC field.The development USB2.0 that experienced by for many years has become the first-selected interface of high speed data transfer equipment, and transmission rate is promoted to 480Mbps from 12Mbps during USB1.1 by it, closes 60MB/ second, substantially can meet the rate requirement of most of ancillary equipment.
Along with the raising of transmission rate, people are to the quality requirement of signal transmission also corresponding raising.If USB connector lacks effective signal shielding structure, so signal transmission capabilities dies down, and transmission quality will can not get ensureing.Therefore in order to ensure safety in signals transmission and stable, USB regulation and stipulation USB cable must be shielding conductor.
Prior art generally will, with the signal transmssion line of the cable of wire sheathing (being woven by zinc-plated thin copper wire) as USB connector, make USB cable from the interference of such as electrostatic, electromagnetic wave and so on by wire sheathing.In order to make wire sheathing play desirable shield effectiveness, the metal shell of USB connector reliably need be connected with the wire sheathing of transmission line, otherwise is difficult to even the electric current that electrostatic, Electromagnetic Interference produce to be imported the earth.
The technical information about USB connector can be seen in, as Authorization Notice No. CN2817114Y recommendation has " USB connector of metallic shield gain " in disclosed Chinese patent literature; And for example Authorization Notice No. CN201584523U provides " USB earthing device "; For another example Authorization Notice No. CN202373771U introduces has " a kind of USB connector with function of shielding "; And then have " USB connector " as publication No. CN103259113A discloses, etc.
Technical information about USB connector high-frequency signal transmission wire can be seen in equally in disclosed Chinese patent literature, as application for a patent for invention publication number CN101527179A recommendation has " a kind of high-frequency signal transmission wire ", the famous high-frequency signal transmission being applicable to USB of this patent application, it is as screen with metal tape.And for example application for a patent for invention publication number CN101556844A provides " high-frequency signal transmission wire and preparation method thereof ", the famous high-frequency signal transmission being applicable to USB3.0 of this patent application scheme, and make screen by braid, specifically can walk to the 3rd page of the 3rd row see specification text the 2nd page of inverse the 4th of this patent application.
It is formed by thin copper wire mesh grid or be made up of metal tape that the version of the metal mesh shield layer that the USB connector high-frequency signal transmission wire in prior art is used mainly contains following two kinds: one; Two is be made up of aluminum-magnesium alloy wire mesh grid.Although the former can meet the welding requirements with connector, expensive, although the latter has relatively cheap strong point compared with the former, the welding requirements with connector cannot be met.Therefore between both, how to find the problem of rational balance point to suffer from industry for a long time, and expect to break through.
For above-mentioned prior art, the applicant has made good try lastingly, finally finds a way to resolve the problem, and defines technical scheme described below.
Summary of the invention
Task of the present utility model is to provide a kind of and metal mesh shield layer can be made not only to have contributed to embodying economy but also be conducive to meeting with connector good welds, be of value to and embody excellent shield effectiveness and use and ensure stablizing and the USB connector high-frequency signal transmission wire that shields of the tin-coated copper plated aluminium magnesium that overall weight is alleviated of Signal transmissions.
Task of the present utility model has been come like this, a kind of USB connector high-frequency signal transmission wire of tin-coated copper plated aluminium magnesium shielding, comprise core, be positioned at the metal mesh shield layer outside core and oversheath successively, core comprises a pair power delivery conductor, a pair Signal transmissions conductor and a metal screen layer, a pair power delivery conductor is coated with power delivery insulating layer of conductor outward separately, and a pair Signal transmissions conductor is coated with Signal transmissions insulating layer of conductor outward separately, and a pair power delivery conductor and a pair Signal transmissions conductor stranded each other, metal screen layer by a pair power conductor and a pair signal conductor jointly coated, be characterised in that: described metal mesh shield layer is woven by tin-coated copper plated aluminium magnesium metal silk and forms.
In a specific embodiment of the present utility model, be provided with a ground wire between described metal screen layer and described metal mesh shield layer, this ground wire is bare copper wire or the tinned copper wire of diameter 0.1-0.3 ㎜.
In another specific embodiment of the present utility model, a pair described power delivery wire is bare copper wire or tinned wird.
In another specific embodiment of the present utility model, a pair described Signal transmissions conductor is bare copper wire or tinned wird.
In another specific embodiment of the present utility model, described power delivery insulating layer of conductor is polypropylene, polyethylene, polyvinyl chloride or fluoroplastics.
Also have in a specific embodiment of the present utility model, described Signal transmissions insulating layer of conductor is polypropylene, polyethylene, polyvinyl chloride or fluoroplastics.
More of the present utility model and in a specific embodiment, described metal screen layer is metal tape, and with vertical bag-like state by a pair described power conductor and signal conductor jointly coated.
In an of the present utility model and then specific embodiment, described metal tape is aluminium foil strip, and the thickness of this aluminium foil strip is 0.01-0.08 ㎜.
Of the present utility model again more and in a specific embodiment, the diameter of described tin-coated copper plated aluminium magnesium metal silk is 0.1-0.3 ㎜.
In an again of the present utility model and then specific embodiment, described oversheath is chlorosulfonated polyethylene.
The technical scheme that the utility model provides, owing to metal mesh shield layer be have employed the metallic shield net woven by tin-coated copper plated aluminium magnesium metal silk, thus not only can embody relatively cheap but also can meet the welding requirements with connector; Because metal screen layer and metal mesh shield layer can play excellent shield effectiveness, the stability of Signal transmissions thus can be ensured; Because tin-coated copper plated aluminium magnesium metal silk is little relative to the quality of copper wire, the weight of transmission line thus significantly can be alleviated.
