Description
Technical field:
This utility model relates to flexible flat data wire, particularly relates to the improvement of flexible shielding flat data line.
Background technology:
Flexible shielding flat data line is a kind of flexible flat data line component for signal transmission, have can arbitrarily bend, high speed transmission of signals, shielding interference signal and can arbitrarily select the advantage such as wire count and spacing, make on line convenient, greatly reduce electronic product volume, reduce production cost, improve production efficiency；It is widely used in the various electronic products such as computer, printer, mobile phone, liquid crystal display connecting between parts, in modern electrical equipment, nearly ubiquitous.
Current flexible shielding flat data line is by wire body, aluminum film and metal reinforcement plate are constituted, wherein wire body is placed in two-layer coating by many parallel distributions and metallic conductor spaced apart from each other has between the insulation film of PUR and hot-forming constitutes, the metallic conductor exposed formation joint of wire body end is the most gold-plated, the one side of metal reinforcement plate is mucilage glue surface, for metal reinforcement plate being adhered to the end of wire body, to increase the mechanical strength of joint, the another side of metal reinforcement plate is to patch face, during for patching, metal reinforcement plate contacts with the ground electrode on socket and electrically connects, aluminum film is pasted onto the outer surface of wire body and electrically connects with metal reinforcement plate, thus operationally make 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, the contact resistance between ground electrode on metal reinforcement plate and socket has a little increase, causing shield effectiveness to decline, this is mainly caused by the electrochemical reaction occurred after different metal material (or metal material of different component) contacts；2. flexible shielding flat data line unavoidably will repeatedly plug during normal operation and maintenance, the Gold plated Layer causing metallic conductor surface sometimes is worn and torn, cause metallic conductor surface oxidation and loose contact, cause fault, and the flexible shielding flat data line of same size model many times it is not easily found in working site, can only again make joint (to make joint to refer to remove plastic film with professional tool, and make the metallic conductor in plastic film exposed, form new joint), owing in new joint, metallic conductor is the most gold-plated, also easily oxidation causes loose contact and affects work.On the other hand, flexible shielding flat data line (particularly winding displacement many, the flexible shielding flat data line of length length), merely because joints wear is just scrapped, is waste and unfortunately really；3. to be often in the temperature difference big for flexible shielding flat data line, frequently flexure and bending, electromagnetic radiation pollution, chemical contamination, in the use environment that light pollution etc. are the most severe and complicated, even work in outdoor open-air atmosphere, colloid adhesion strength is easily caused to decline, metallic conductor is caused to deform with insulation film, cracking and separation, between metallic conductor, insulation impedance declines, metallic conductor play or off normal, have a strong impact on the electrical property of flexible flat data wire, even cause disorder and interruption that data transmit, and cause metallic conductor and insulation film deformation, cracking, one of reason separated is that insulation film is the strongest with the ageing-resistant performance of the PUR being coated on insulation film, in electromagnetic radiation pollution, chemical contamination, in the environment of the multiple polluter of light pollution etc. the most aging.At present, shield effectiveness good, ageing-resistant again can nonexpondable flat data line the rarest, the most not in data and media report find.
Utility model content:
For the above-mentioned deficiency existing for prior art, technical problem to be solved in the utility model is to provide for a kind of aging resistance and the nonexpondable flat data line of energy, it can not only increase the contact pressure between the ground electrode on metal reinforcement plate and socket, thus preferably reduce the contact resistance between the ground electrode on metal reinforcement plate and socket, improve the shield effectiveness of flexible shielding flat data line, the ageing-resistant performance of flat data line can also be improved, deformation and cracking it is not easy in adverse circumstances, and can reuse, reduce waste.
In order to solve above-mentioned technical problem, this utility model solves the scheme of technical problem: aging resistance and the nonexpondable flat data line of energy, including wire body, aluminum film and metal reinforcement plate, the metallic conductor of described wire body end is exposed and forms joint, 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, it is machined with some rectangular through-hole on described metal reinforcement plate, the surface gold-plating of described metallic conductor, described wire body is coated with poly tetrafluoroethylene.
After using such scheme, it is machined with some rectangular through-hole due on 1. metal reinforcement plate, after metal reinforcement plate inserts socket, reduce the contact area between metal reinforcement plate and ground electrode, patch pressure certain in the case of, add the footprint pressure between metal reinforcement plate and ground electrode, thus add the contact pressure between metal reinforcement plate and ground electrode, this makes the contact resistance between metal reinforcement plate and ground electrode be substantially reduced, metal reinforcement plate and the aluminum film being electrically connected can preferably be in zero potential state, play good shielding action；2. in the surface gold-plating of metallic conductor, when again making joint, joint is the most gold-plated, the most oxidizable, it is possible to reach performance indications and the using effect of new flat data line, reduces waste.It addition, when can not find the flexible shielding flat data line of same size model, using the method again making joint, faulty equipment can be made to resume work, reduce user's loss；3. it is coated with poly tetrafluoroethylene in wire body, politef has excellent chemical stability and anti-electromagnetic-radiation pollutes, light pollution performance, in electromagnetic radiation pollution, chemical contamination, the environment of the multiple polluter of light pollution etc. is not easy aging, not easily lead to metallic conductor deform with insulation film, cracking and separation, flexible flat data wire is wrapped by poly tetrafluoroethylene, be equivalent to wear a coat keeping out many heavily contaminateds to flexible flat data wire, improve stability and the reliability of flexible flat data wire, 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, metal reinforcement plate is made to avoid socket to the friction of the lateral opening wall of the length of rectangular through-hole on metal reinforcement plate during inserting socket, and the deformation that caused by friction and crimping, extend metal reinforcement plate and the service life of flexible flat data wire.
Direction of insertion refers to direction of motion during metal reinforcement plate insertion socket.
Some rectangular through-hole on metal reinforcement plate can be processed to form by manufacturing the mould of metal reinforcement plate, and its technique is uncomplicated, it is possible to realize.
