Description
Technical field:
The present invention relates to flexible shielding flat data line, particularly relate to the improvement of flexible shielding flat data line stiffening plate。
Background technology:
Flexible shielding flat data line is a kind of flexible shielded flat data wire assembly for signal transmission, have can arbitrarily bend, high speed transmission of signals 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 between parts and connects, in modern electrical equipment, nearly ubiquitous。
Flexible shielding flat data line is mainly made up of metallic conductor, insulation film, aluminum film and a few part of stiffening plate, wherein metallic conductor mostly adopts flat elongated copper conductor, concrete structure is to be connected to insulation film with melt viscosity respectively in the both sides of many parallel distributions and metallic conductor spaced apart from each other, stiffening plate is then adhered to the two ends of flexible shielding flat data line, aluminum film is pasted onto on insulation film, and the metallic conductor of flexible shielding flat data thread end is exposed and forms joint。Due to computer, printers etc. exist to be repaired, change parts and periodic maintenance, need repeatedly plug flexible shielding flat data line, this just requires that the end of flexible shielding flat data line has certain mechanical strength, thus the mucilage glue surface that the reinforcement degree being bonded in flexible shielding flat data line two ends must have certain mechanical strength body is plane, mucilage glue surface is stained with PUR, the face of patching is smooth surface, plate body adopts melt viscosity to be connected on the end of flexible shielding flat data line, the aluminum film being pasted onto on insulation film electrically connects with plate body, when patching, stiffening plate contacts with the ground electrode on socket and electrically connects, aluminum film is made to be in zero potential state all the time, thus playing good shielding action。The weak point of the flexible shielding flat data line of this structure is；1. after stiffening plate uses a period of time, the contact resistance between ground electrode on stiffening plate and socket has a little increase, causing that shield effectiveness declines, this is mainly caused by the electrochemical reaction occurred after different metal material (or metal material of different component) contacts；2. the mucilage glue surface of plate body is the plane of smoother, its surface tension is smaller, cause that the firmness between stiffening plate and flexible shielding flat data line can not be significantly high, can be easily separated between stiffening plate and flexible shielding flat data line so that flexible shielding flat data report from a liner is given up。In the actual maintenance maintenance process of electronic product, especially flexible shielding flat data line is after repeatedly plug, often occur because stiffening plate separates, with flexible shielding flat data line, the phenomenon causing flexible shielding flat data report from a liner useless, there is no good solution at present, also do not find in data and media report。
Summary of the invention:
Above-mentioned deficiency existing for prior art, the technical problem to be solved is to provide for a kind of reduction contact resistance and bonding firmly stiffening plate, it can reduce the contact resistance between the ground electrode on stiffening plate and socket preferably, improve the shield effectiveness of flexible shielding flat data line, and can firmly be bonded on flexible shielding flat data line and be not readily separated。
In order to solve above-mentioned technical problem, this invention address that the scheme of technical problem is: reduce contact resistance and bonding firmly stiffening plate, plate body including the aluminum matter with certain elastic and thickness, the one side of this plate body is mucilage glue surface, the another side of this plate body is to patch face, described patch face be provided with the sharp tooth of some evaginations straight patch tooth bar, described mucilage glue surface is provided with the bonding tooth bar of the sharp tooth bending of some evaginations。
After adopting such scheme, tooth bar is patched due to what the face that patches of 1. plate body was provided with the sharp tooth of some evaginations, after stiffening plate inserts socket, patched the tooth bar that patches of sharp tooth on face by plate body to contact with ground electrode, reduce the contact area that plate body patches between face and ground electrode, when patching pressure and being certain, add the footprint pressure that plate body patches between face and ground electrode, thus increasing the contact pressure that plate body patches between face and ground electrode, this makes the contact resistance that plate body patches between face and ground electrode be substantially reduced, aluminum film can better be in zero potential state, play good shielding action；2. mucilage glue surface is provided with the bonding tooth bar of the sharp tooth bending of some evaginations, add PUR to contact with stiffening plate and bonding area, effectively raise firmness, so that flexible shielding flat data line and stiffening plate are not readily separated, on the other hand, flexible shielding flat data line is in the process pulled out and insert, the stress size of flexible shielding flat data line and stiffening plate is incomplete same, the trend that relative motion occurs is had along stiffening plate surface between flexible shielding flat data line and stiffening plate, this also results in flexible shielding flat data line and separates with stiffening plate, and the bonding tooth bar of the sharp tooth bending of some evaginations on stiffening plate, very effective hinder this relative motion, and be the relative motion of all directions, so that flexible shielding flat data line and stiffening plate are not readily separated。
The bearing of trend patching tooth bar is identical with direction of insertion so that stiffening plate minimizing in the process inserting socket patches the abrasion of pointed tooth on tooth bar, extends the service life of stiffening plate。
Direction of insertion refers to direction of motion during stiffening plate insertion socket。
Plate body is patched the bonding tooth bar patching on tooth bar and mucilage glue surface on face and can be processed to form by the mould of manufacture plate body, and its technique is uncomplicated, it is possible to realize。
