Abstract
The utility model relates to a flexible shield flat data line especially relates to the improvement of stiffening plate for the flexible shield flat data line. The utility model discloses can reduce contact resistance's stiffening plate, including the plate body that has the aluminium matter of certain elasticity and thickness, the one side of this plate body is adhesion surface, and the another side of this plate body connects the face of inserting, adhesion surface is the plane, connect the straight rack of sharp cusp that is equipped with a plurality of evaginations on the face of inserting. Contact resistance between reduction stiffening plate that it can be better and the telluric electricity field on the socket improves flexible shield flat data line's shielding effect.
Description
Technical field:
This utility model relates to flexible shielding flat data line, particularly relates 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 connecting between parts, 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 uses 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.Repair owing to computer, printer etc. exist, 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 reinforcement degree being bonded in flexible shielding flat data line two ends must have certain mechanical strength and bonding firmly.Existing stiffening plate is the plate body with certain elastic aluminum matter with thickness, the mucilage glue surface of this plate body is plane, PUR it is stained with on mucilage glue surface, the face of patching is smooth surface, plate body uses melt viscosity to be connected on the end of flexible shielding flat data line, and the aluminum film being pasted onto on insulation film electrically connects with plate body, and when patching, stiffening plate contacts with the ground electrode on socket and electrically connects, make aluminum film be in zero potential state all the time, thus play good shielding action.The weak point of the flexible shielding flat data line of this structure is；After stiffening plate uses a period of time, the contact resistance between ground electrode on stiffening plate and socket has a little increase, shield effectiveness is caused to decline, this is mainly caused by the electrochemical reaction occurred after different metal material (or metal material of different component) contacts, there is no preferable solution at present, 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 is to provide for a kind of stiffening plate that can reduce contact resistance, it can preferably reduce the contact resistance between the ground electrode on stiffening plate and socket, improves the shield effectiveness of flexible shielding flat data line.
In order to solve above-mentioned technical problem, this utility model solves the scheme of technical problem: can reduce the stiffening plate of contact resistance, 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 mucilage glue surface is plane, described in patch face and be provided with the tooth bar that the sharp tooth of some evaginations is straight.
After using such scheme, the tooth bar of the sharp tooth of some evaginations it is provided with due to the face that patches of plate body, after stiffening plate inserts socket, contact with ground electrode owing to plate body patches the tooth bar of sharp tooth on face, reduce the contact area that plate body patches between face and ground electrode, patch pressure certain in the case of, add the footprint pressure that plate body patches between face and ground electrode, thus increase the contact pressure that plate body patches between face and ground electrode, this contact resistance making plate body patch between face and ground electrode is substantially reduced, aluminum film can preferably be in zero potential state, play good shielding action.
The bearing of trend of tooth bar is identical with direction of insertion so that stiffening plate reduces the abrasion of pointed tooth on tooth bar during inserting socket, extends the service life of stiffening plate.
Direction of insertion refers to direction of motion during stiffening plate insertion socket.
Plate body patches the tooth bar of sharp tooth on face and can be processed to form by manufacturing the mould of plate body, and its technique is uncomplicated, it is possible to realize.
The cross section of tooth bar is triangle, it is simple to compression molding.
Accompanying drawing illustrates:
The stiffening plate that this utility model can reduce contact resistance below in conjunction with the accompanying drawings with detailed description of the invention further describes.
Fig. 1 is the structural principle schematic diagram that this utility model can reduce the stiffening plate detailed description of the invention of contact resistance.
Detailed description of the invention:
In Fig. 1, the stiffening plate of contact resistance can be reduced, plate body 1 including the aluminum matter with certain elastic and thickness, the one side of this plate body 1 is mucilage glue surface 4, the another side of this plate body 1 is to patch face 2, described mucilage glue surface 4 is plane, described in patch face 2 and be provided with the tooth bar 3 (only having drawn a toothed rack in figure) that the sharp tooth of some evaginations is straight, the cross section of tooth bar 3 is triangle.The bearing of trend of tooth bar 3 is identical with direction of insertion so that stiffening plate reduces the abrasion of pointed tooth on tooth bar 3 during inserting socket, extends the service life of stiffening plate.The tooth bar 3 of the sharp tooth of some evaginations it is provided with due to the face that patches 2 of plate body 1, after stiffening plate inserts socket, contact with ground electrode owing to plate body 1 patches the tooth bar 3 of sharp tooth on face 2, reduce plate body 1 and patch the contact area between face 2 and ground electrode, patch pressure certain in the case of, add plate body 1 and patch the footprint pressure between face 2 and ground electrode, thus increase plate body 1 and patch the contact pressure between face 2 and ground electrode, this contact resistance that plate body 1 is patched between face 2 and ground electrode is substantially reduced, aluminum film can preferably be in zero potential state, play good shielding action.
Claims (2)
1. can reduce the stiffening plate of contact resistance, plate body (1) including the aluminum matter with certain elastic and thickness, the one side of this plate body (1) is mucilage glue surface (4), the another side of this plate body (1) is to patch face (2), described mucilage glue surface (4) is plane, it is characterized in that: described in patch face (2) and be provided with the tooth bar (3) that the sharp tooth of some evaginations is straight.
