But, the Main Ingredients and Appearance of gold plating bath used when electroplating due to Gold plated Layer 123 is cyaniding cyanogen potassium and Cymag etc., cyanide has hypertoxicity to belong to poisonous substance control, in the world, several major country is gradually disabled at present, and surging along with environmental consciousness in recent years, consumer also starts to compare tendency and buys the product meeting environment protection requirement.In addition, gold-plated cost is originally just higher, adds price of gold hurricane in recent years and rises, and reduces the thickness of Gold plated Layer 123 or finding other substitute has been considerable development trend now.
utility model content
Know and know that the conductive junction point at flexible flat cable two ends is in order to maintain good electrically conducting, and conductive junction point of being everlasting sequentially electroplates intermediary layer and Gold plated Layer, so cause cost of manufacture to increase the problem with environmental pollution, the demand in client and market can not be met.
The utility model provides a kind of flexible flat cable structure, include one first insulating barrier, a conductor layer, one second insulating barrier and a metallized ceramic electrodeposited coating, wherein conductor layer is arranged on the first insulating barrier, conductor layer comprises many strip metals wire arranged in parallel, second insulating barrier is arranged on conductor layer, those plain conductors of conductor layer expose to the second insulating barrier to form multiple contact, and metallized ceramic electrodeposited coating is arranged on each contact.
This novel provided flexible flat cable structure, it by forming a metallized ceramic electrodeposited coating in the mode of plating on the contact of flexible flat cable, the coating structure of this metallized ceramic electrodeposited coating itself is utilized to have the characteristic preventing oxide etch and provide good conductive degree, replace the intermediary layer and Gold plated Layer knowing and know and use in technology, therefore can solve to know and know that the cost of manufacture that technology uses Gold plated Layer easily to produce increases the problem with environmental pollution, so can meet the demand in client and market.

Embodiment
Refer to shown in Fig. 3 to Fig. 4; it is the preferred embodiment of this novel flexible flat cable structure, and this flexible flat cable structure 2 includes one first insulating barrier 21, conductor layer 22,1 second insulating barrier 23, metallized ceramic electrodeposited coating 24, screen 25 and a protective layer 26.
Conductor layer 22 is arranged on the first insulating barrier 21, this conductor layer 22 comprises many strip metals wire arranged in parallel, second insulating barrier 23 is arranged on conductor layer 22, the end of those plain conductors of conductor layer 22 exposes to the second insulating barrier 23 to form multiple contact 221, and metallized ceramic electrodeposited coating 24 is arranged on each contact 221.Be understandable that, alternatively, also the end of those plain conductors can be exposed to the first insulating barrier 21 to form those contacts 221.
Screen 25 is arranged on the second insulating barrier 23; protective layer 26 is arranged on screen 25; this screen 25 for prevent external electromagnetic wave interference and have electromagnetic shielding protection effect, its be mostly adopt aluminium foil, protective layer 26 is the use as guard shield layer 25.In addition, between conductor layer 22 and the first insulating barrier 21 and between conductor layer 22 and the second insulating barrier 23, an insulation glue-line (not illustrating) is all respectively provided with, so to be coated and fixed on by conductor layer 22 between first insulating barrier 21 and the second insulating barrier 23.
In the present embodiment; the thickness of this metallized ceramic electrodeposited coating 24 is between 0.05 μm to 5 μm; it is formed on contact 221 in the mode of plating; the function of this metallized ceramic electrodeposited coating 24 is mainly replacing the intermediary layer 122 and Gold plated Layer 123 knowing and know that technology uses, can not oxide etch and maintain low contact impedance and the good requirement of conductivity for the protection of contact 221.This metallized ceramic electrodeposited coating 24 is generally metal carbides and forms, and this is because metal carbides not only have the characteristic of general ceramic corrosion-proof wear, also has glossiness and the conductivity of metal simultaneously.In the present embodiment, this metallized ceramic electrodeposited coating 24 for having the chromium carbide electrodeposited coating of better conductivity, its common structure thing formed for chromium element and carbon.Alternatively, metallized ceramic electrodeposited coating 24 is with chromium carbide base (Chromium Carbide base, CrC base) be the metallized ceramic of composition, preferably this metallized ceramic electrodeposited coating 24 is formed by the compound of chromium and chromium carbide.
It is worth mentioning that, the metallized ceramic electrodeposited coating 24 that the utility model uses only needs just metallized ceramic electrodeposited coating 24 to be formed on contact 221 through an electroplating process, and its material cost used is also low than Jin Lai get.Therefore the utility model is known compared with technology with knowing, the utility model does not need through second time electroplating processing procedure to electroplate different material layer, and electroplating process of the present utility model effectively can reduce manufacturing cost compared to knowing the gold-plated processing procedure known and comparatively meet environment protection requirement, therefore can be used to solve know and know that the cost of manufacture that technology easily produces increases the problem with environmental pollution.
In sum, this novel flexible flat cable structure utilizes and form a metallized ceramic electrodeposited coating in the mode of plating on the contact of flexible flat cable, the coating structure of this metallized ceramic electrodeposited coating itself is utilized to have the characteristic preventing oxide etch and provide good conductive degree, replace the intermediary layer and Gold plated Layer knowing and know and use in technology, therefore can solve to know and know that the manufacturing cost that technology uses Gold plated Layer easily to produce increases the problem with environmental pollution, so can meet the demand in client and market.
Above-mentioned detailed description be for this novel one preferably possible embodiments illustrate, only this embodiment is not intended to limit this novel right, under all other does not depart from this novel disclosed skill spirit, the equalization change that completes is changed with modifying, and all should be contained in originally novel contained right.
