Abstract

The utility model relates to a soft ribbon cable structure, consisting of a first insulation layer, a first conductor layer, a second insulating layer, a second conductor layer and a third insulating layer which are pressed into a whole from top to down. The first conductor layer and the second insulating layer are respectively made of a plurality of conducting wires which are equidistantly arrayed at interval; and both ends of the first conductor layer and the second conductor layer are a plurality of connection points exposed at outside; in this way, both the upper and the lower surfaces of the soft ribbon cable are provided with a plurality of connection points which are inserted and connected with an electric connector provided with top terminators and terminators beneath, thus shortening the width of the soft cable, saving material, and facilitating the manufacture.

Description

The flexible flat cable structure

Technical field

The utility model relates to a kind of flexible flat cable structure, refer to a kind of flexible flat cable one pressing and forming especially after, all have the structure of contact in upper and lower surface, with effective shortening flexible flat cable width and simplify the flexible flat cable structure of processing procedure.

Background technology

Flexible flat cable (Flexible Flat Cable, FFC) be a kind of signal transmission assembly, itself have advantages such as deflection arbitrarily, high signal transmittability, therefore be applied in widely in many electronic products, this flexible flat cable is to use with the electric connector collocation, so that signal is stable and be passed to an other end fast by an end, and reach the purpose that signal transmits.

In general, the internal structure of this flexible flat cable is to be the layer of metal conductor layer, upper surface and lower surface at metal carbonyl conducting layer paste a layer insulating more respectively, and outside the contact of the rear and front end of metal carbonyl conducting layer can be exposed to, make flexible flat cable have the function of transmission,, have the characteristic that can bend arbitrarily because the metal carbonyl conducting layer of flexible flat cable and insulating barrier are all very thin, and can be according to different demands, it is identical to produce different thickness of insulating layer.

But, general flexible flat cable only has plural contact at single mask, and another side does not then have contact, when on the electric connector of desiring to be applied to have upper and lower two row's terminals, two flexible flat cables of then must pegging graft cause inconvenient in the use and have increased time of assembling.And work as the flexible flat cable contact more for a long time, and it is very wide that the width of flexible flat cable can become, and cause the waste of usage space, and influence the circuit layout of other electronic building brick.

Summary of the invention

The purpose of this utility model is that a kind of flexible flat cable structure is being provided, by improvement of the present utility model, make the upper and lower surface of flexible flat cable structure all have plural contact, being plugged in electric connector, and can effectively shorten the width of flexible flat cable with upper and lower two row's terminals.

The purpose of this utility model is that a kind of flexible flat cable structure is being provided, and by the flexible flat cable structure that the one pressing forms, makes man-hour to save material, simplification making flow process and shortening.

For realizing the described purpose in prostatitis, the utility model provides a kind of flexible flat cable structure, this kind flexible flat cable structure, be by first insulating barrier, conductor layer No.1, second insulating barrier, second conductor layer and the 3rd insulating barrier from top to bottom the one pressing form, this conductor layer No.1 and second conductor layer are to be arranged by the complex lead equi-spaced apart respectively to form, and the two ends of this conductor layer No.1 and second conductor layer are to be exposed to form plural contact outward.

The utlity model has following beneficial effect: this conductor layer No.1 and second conductor layer are to be arranged by the complex lead equi-spaced apart respectively to form, and the two ends of this conductor layer No.1 and second conductor layer are to be exposed to form plural contact outward; By this, make flexible flat cable all have plural contact, be used for being plugged in electric connector, and reach the effect that shortens the flexible flat cable width with upper and lower row's terminal on upper and lower surface.

Embodiment

Please consult Figure 1 and Figure 2 simultaneously, it is side cutaway view for stereo appearance figure of the present utility model and Figure 1A-A line segment, find out that by knowing among the figure flexible flat cable structure 1 of the present utility model mainly is to be formed by first insulating barrier 11, conductor layer No.1 21, second insulating barrier 12, second conductor layer 22 and the 13 one pressings of the 3rd insulating barrier.This conductor layer No.1 21 and second conductor layer 22 are all arranged by

complex lead

211 and 221 equi-spaced apart and are formed, and the front end of these leads 211 and 221 and rear end (icon only shows front end) are to be exposed to profile pluralize contact 212 and 222.By above-mentioned structural design, make flexible flat cable structure 1 of the present utility model all have the corresponding mutually

contact

212 and 222 that is provided with of plural number in upper surface and lower surface, therefore not only can be plugged on the electric connector (not shown) with upper and lower row's terminal and use, and can reach the effect that shortens flexible flat cable structure 1 width.

Please consult Fig. 3 and shown in Figure 4 again, be stereo appearance figure and the part front view for another embodiment of the utility model, the utility model flexible flat cable structure 1 is also formed by first insulating barrier 11, conductor layer No.1 21, second insulating barrier 12, second conductor layer 22 and the 13 one pressings of the 3rd insulating barrier as shown in the figure.Wherein the complex lead 211,221 of this conductor layer No.1 21 and second conductor layer 22 also can be the setting that is staggered, and also makes flexible flat cable structure 1 all have the

contact

212 and 222 of interlaced setting in upper and lower surface.

By above explanation as can be known, greatest feature of the present utility model is pressed on the conductor layer No.1 and second conductor layer respectively between first insulating barrier, second insulating barrier and the 3rd insulating barrier, the contact at the conductor layer No.1 and the second conductor layer two ends is exposed, to make the flexible flat cable structure all have plural contact in upper and lower surface, be used for being plugged in electric connector, and reach shortening flexible flat cable width, simplify the making flow process and shorten the effect of making man-hour with upper and lower row's terminal.

Above-mentioned detailed description is at a kind of preferable possible embodiments explanation of the utility model, but this embodiment is not in order to limit claim of the present utility model, all other do not break away from the equalization of being finished under the skill spirit that the utility model discloses to be changed and modifies change, all should be contained in the claim that the utility model contains.
