Description

Aging resistance shielded flat data wire

Technical field:

This utility model relates to flexible flat data wire, particularly relates to flexible shielding flat data line Improve.

Background technology:

Flexible shielding flat data line is a kind of flexible flat data line for signal transmission Assembly, have can arbitrarily bend, high speed transmission of signals, shielding interference signal and arbitrarily selecting The advantage such as wire count and spacing so that on line is convenient, greatly reduces electronic product volume, reduces Production cost, improves production efficiency；It is widely used in computer, printer, mobile phone, liquid crystal display The various electronic product such as device connects between parts, in modern electrical equipment, nearly ubiquitous.

Current flexible shielding flat data line is made up of, wherein wire body, aluminum film and metal reinforcement plate Wire body is placed in two-layer coating by many parallel distributions and metallic conductor spaced apart from each other PUR Between insulation film and hot-forming composition, the metallic conductor of wire body end is exposed and forms joint, The one side of metal reinforcement plate is mucilage glue surface, for metal reinforcement plate being adhered to the end of wire body, with Increasing the mechanical strength of joint, the another side of metal reinforcement plate is to patch face, metal when being used for patching Stiffening plate contacts with the ground electrode on socket and electrically connects, and aluminum film is pasted onto the appearance of wire body Face also electrically connects with metal reinforcement plate, thus operationally makes aluminum film be in zero potential state all the time, Play good shielding action.The weak point of the flexible shielding flat data line of this structure is； 1. after metal reinforcement plate uses a period of time, between the ground electrode on metal reinforcement plate and socket Contact resistance has a little increase, causes shield effectiveness to decline, and this is mainly by different metal materials The electrochemical reaction occurred after material (or metal material of different component) contact causes；The most soft Property shielded flat data wire be often in that the temperature difference is big, frequently flexure and bending, electromagnetic radiation pollution, In the use environment that chemical contamination, light pollution etc. are the most severe and complicated, even work in outdoor dew It environment, easily causes colloid adhesion strength to decline, and causes metallic conductor to deform with insulation film, open Splitting and separate, between metallic conductor, insulation impedance declines, and metallic conductor play or off normal has a strong impact on The electrical property of flexible flat data wire, even causes disorder and interruption that data transmit, and causes gold Belong to conductor and insulation film deform, ftracture, one of the reason that separates be insulation film be coated in exhausted The ageing-resistant performance of the PUR on edge thin film is not strong, at electromagnetic radiation pollution, chemical contamination, light Pollute etc. multiple polluter environment in the most aging.There is no preferable solution at present, also Do not find in data and media report.

Utility model content:

For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model Be to provide for a kind of aging resistance shielded flat data wire, it can preferably reduce metal reinforcement plate with The contact resistance between ground electrode on socket, improves the shielding effect of flexible shielding flat data line Really, moreover it is possible to improve the ageing resistace of flat data line, adverse circumstances are not easy deformation and open Split.

In order to solve above-mentioned technical problem, this utility model solves the scheme of technical problem and is: anti-ageing Change shielded flat data wire, including wire body, aluminum film and metal reinforcement plate, the gold of described wire body end Genus conductor is exposed and forms joint, and described metal reinforcement plate is adhered to the end of described wire body, described Aluminum film is pasted onto the outer surface of described wire body and electrically connects with described metal reinforcement plate, and described metal is mended It is machined with some rectangular through-hole on strong plate, described wire body is coated with poly tetrafluoroethylene.

After using such scheme, owing to being machined with some rectangular through-hole on metal reinforcement plate, metal is mended After strong plate inserts socket, reduce the contact area between metal reinforcement plate and ground electrode, connecing In the case of interpolated pressure is certain, add the footprint pressure between metal reinforcement plate and ground electrode, Thus adding the contact pressure between metal reinforcement plate and ground electrode, this makes metal reinforcement plate And the contact resistance between ground electrode is substantially reduced, metal reinforcement plate and the aluminum film being electrically connected Can preferably be in zero potential state, play good shielding action.On the other hand, in wire body Being coated with poly tetrafluoroethylene, politef has excellent chemical stability and anti-electromagnetic-radiation Pollution, light pollution performance, at the many heavily contaminateds of electromagnetic radiation pollution, chemical contamination, light pollution etc. The environment in source is not easy aging, not easily lead to the deformation of metallic conductor and insulation film, cracking And separation, flexible flat data wire is wrapped by poly tetrafluoroethylene, is equivalent to flexible flat number Wear a coat keeping out many heavily contaminateds according to line, improve the stability of flexible flat data wire And reliability, preferably ensure that the product quality of flexible flat data wire and service life and Environmental suitability

The direction that the long limit of rectangular through-hole extends is identical with direction of insertion so that metal reinforcement plate is being inserted Avoid socket to the rubbing of the lateral opening wall of the length of rectangular through-hole on metal reinforcement plate during entering socket Wipe, and the deformation that caused by friction and crimping, extend metal reinforcement plate and flexible flat data The service life of line.

Direction of insertion refers to direction of motion during metal reinforcement plate insertion socket.

Some rectangular through-hole on metal reinforcement plate can add by manufacturing the mould of metal reinforcement plate Work is formed, and its technique is uncomplicated, it is possible to realize.
