Abstract
The utility model relates to a flexible wiring conductor structure. The utility model changes a traditional manner that a tinned wire is directly used as a conductor. The outermost layer of the flexible wiring conductor is coated with gold, or at least the outermost layer of the contacting part of the conductor is coated with the gold, thereby, the utility model ensures the well signal transmission capability between the contacting part and a butt connector, and raises the service life of the flexible wiring conductor.
Description
Technical field
The utility model is relevant for a kind of soft rowed line structure, particularly relevant for a kind of soft arranging wire with satisfactory electrical conductivity, reliability conductor structure.
Background technology
Flexible flat cable (generally abbreviates FFC as; Flexible Flat Cable) is that assembly is used in a kind of signal transmission, itself has advantages such as deflection arbitrarily, high signal transmittability, be widely used at present in many electronic products, and use amount increases severely year after year.In general, soft arranging wire is many to be assembled jointly with the plug type connector, can promote its switching performance, easily slottingly easily pulls out.The simple structure of soft arranging wire own, as shown in Figure 1, its basic structure mostly is with insulation glue-line 10 and coats tabular (or wire) conductor that plurality of parallel arranges up and down and constitute, and at the soft arranging wire side segment conductor is exposed, form a contact site 12, so that electrically connect with the plug type connector.
Traditionally, flexible flat cable uses tinned wird as conductor mostly, because tin has good conductibility, with low cost, easily plating and can protect advantage such as bare copper wire.But along with the continuous lifting of signal transmission technology in recent years, traditional tinned wird can't provide the transmittability of equity gradually, add tin coating the integrity problem existence that tin Hu (Whisker) or the like easily causes the signal transmission failure takes place easily, lose its applicability gradually.Therefore, each tame manufacturer is invariably with the good conductor structure of the finding out alternative tinned wird improvement target as soft arranging wire of future generation.The utility model is promptly improved at this subject under discussion.
Summary of the invention
The purpose of this utility model is providing a kind of soft arranging wire conductor structure, to improve the signal transmittability of soft arranging wire.
Another purpose of the present utility model is providing a kind of soft arranging wire conductor structure, causes problems such as telecommunication inefficacy recklessly to avoid conventional conductor easily to produce tin.
Another purpose of the present utility model is providing a kind of soft arranging wire conductor structure, to improve the reliability and the useful life of soft arranging wire.
The utility model system changes tradition and uses the mode of tinned wird as conductor relevant for a kind of soft arranging wire conductor structure, the conductor outermost layer is imposed gold-plated, or imposes gold-plated at least on the contact site outermost layer of conductor.Plate nickel dam in addition and between conductor and Gold plated Layer,, in the useful life of improving soft arranging wire, guarantee to keep between contact site and the butt connector good signal transmittability simultaneously to strengthen the tack of gold layer.

Embodiment
Embodiment more of the present utility model can be described in detail as follows.Yet except this was described in detail, the utility model can also be widely implemented at other embodiment.That is scope of the present utility model is not subjected to the restriction of the embodiment that proposed, and should be as the criterion with the claim scope that the utility model proposes.Moreover in this manual, the different piece of each assembly is not drawn according to size.Some yardstick is compared with other scale dependent and is exaggerated or simplify, so that clearer description and understanding of the present invention to be provided.
Hereinafter with reference to each icon, the execution mode of the utility model soft arranging wire conductor structure is described:
At first, please refer to shown in Figure 2ly, be soft arranging wire conductor structure one preferred embodiment cutaway view of the present utility model.Primary clustering comprises dielectric film 20, envelope the conductor 21 that plurality of parallel is arranged by upper and lower, this conductor 21 can be divided into outside tin layer 211 and central copper cash 212, and forms a contact site that exposes 22 on side, forms with external connector by contact site 22 to electrically connect.Its formation order at first, coats conductor 21 up and down with dielectric film 20, and expose contact site 22 on side, then removes the tin layer 211 on the contact site 22, forms a nickel dam 23 and a gold medal layer 24 at last on contact site 22 in regular turn.
Conductor described in the foregoing description 21 can be a tinned wird, in addition, can also directly use the bare copper wire of no tin coating to make, can omit and remove tin layer 211, directly coat copper cash 212, on contact site 22, form a nickel dam 23 and a gold medal layer 24 more in regular turn with dielectric film 20.
Please refer to shown in Figure 3, for the utility model reaches a soft arranging wire conductor structure preferred embodiment cutaway view again.In this embodiment, conductor can use the tinned wird that has removed outside tin layer or directly use bare copper wire.At first, around copper cash 212, form a nickel dam 23, coat up and down with dielectric film 20 again, make and form contact site 22 on the side, on contact site 22, form a gold medal layer 24 at last again.
Please refer to shown in Figure 4ly, be the another preferred embodiment cutaway view of soft arranging wire conductor structure of the present utility model.In this embodiment, conductor can or directly use bare copper wire for the tinned wird that removes outside tin layer.At first, on copper cash 212, form a nickel dam 23 and a gold medal layer 24 in regular turn, coat up and down with dielectric film 20 more at last, and on side, form contact site 22.
In above-mentioned several embodiment, contact site 22 positions can also can be the kenels of two-sided contact for having only the single face contact.When contact site 22 is single face, can on the another side of contact site 22, set up a stiffener 25 usually, to increase contact site intensity, stiffener 25 can be loaded onto before plating nickel dam, gold layer, also can install after having plated again, and decided on the actual design demand.When contact site 22 when being two-sided, the nickel dam in the previous embodiment 23 and 24 formation of gold layer symmetrical kenel up and down in regular turn then, meaning promptly, all coating systems coat around the contact site of each electric wire in regular turn.In addition, if in the soft arranging wire plural contact site is arranged, for example on the soft arranging wire two side ends, then the contact site of homonymy can not impose any structure in the foregoing description, looks closely actual demand and decides.
The above is preferred embodiment of the present utility model only, is not in order to limit claim scope of the present utility model.Still can be changed in the category that does not break away from flesh and blood of the present invention and implemented, these variations should still belong to scope of the present utility model.Therefore, category of the present utility model is defined by the claim scope.
