Abstract

The utility model discloses a flexible flat cable, which includes wires arranged at equal intervals and a transparent protection layer. The shape of the protection later is a composite pattern made through the combination of a rectangle and a plurality of circles arranged in the length direction of the rectangle and at equal intervals. The method utilizes the injection molding manner to produce the flexible flat cables, and has the advantages that the process is simplified and the product appearance is easy to control. The flexible flat cable has a simplified structure, can be directly processed and manufactured by adopting the injection molding manner, so as to have the advantage of lower cost.

Description

A kind of soft arranging wire

Technical field

The utility model belongs to cable manufacturing technology field, is specifically related to a kind of soft arranging wire.

Background technology

(Flexible flat cable FFC) is the connecting line structure of a kind of frequent use in electronic installation to soft arranging wire, and in general, it for example is insulating barrier such as polyester film that the pin of typical soft arranging wire is coated with outward usually.The characteristic of soft arranging wire is to have goodish pliability, therefore can provide suitable wiring in narrow space.Printhead, mechanical arm with printer are example, and the work that need move around of these devices is electrically connected so be particularly suitable for soft arranging wire.Other all can see the application of soft arranging wire in consumer electronic product such as camera, mobile phone, computer installation, barcode machine and LCD.

The manufacturing process of present known flexible flat cable, be after earlier lead being taken out line, utilize insulating barrier to form from two direction hot pressing predetermined quantity leads up and down again, to be easy to generate dimensional tolerance in the line process excessive owing to taking out of processing procedure, causes the characteristic impedance error of flexible flat cable bigger.

In addition, at some special occasions, because the diameter of lead is less, and the spacing between adjacent two leads is less, and the flexible flat cable that causes utilizing this conventional method to produce causes waste product because of distortion easily.

The utility model content

The purpose of this utility model provides a kind of designs simplification, easily processing and manufacturing and lower-cost soft arranging wire.

The technical scheme that realizes the utility model purpose is: a kind of soft arranging wire, comprise the lead of equidistant arrangement and be coated on the outer protective clear layer of lead that the cross sectional shape of described protective layer is by rectangle with along the equidistant compound pattern of arranging that a plurality of circle combined of described rectangle length direction; Described each circular diameter is greater than the width of rectangle; Described each circle and corresponding concentric a setting of lead.

In the such scheme, described protective layer is the fluoroplastics protective layers, and the shape of described protective layer left and right sides end all is circular.

The utlity model has positive effect:

(1) winding displacement in the utility model has designs simplification, can adopt the direct processing and manufacturing of injection molding, thereby has lower-cost advantage.

Description of drawings

Fig. 1 is a kind of structural representation of the present utility model.

Reference numeral is: lead 5, protective layer 6, rectangle 61, circular 62.

Embodiment

(embodiment 1, soft arranging wire)

Fig. 1 is a kind of structural representation of the present utility model, has shown a kind of embodiment of soft arranging wire in the utility model.

Present embodiment is a kind of soft arranging wire, see Fig. 1, the lead 5 and the protective clear layer 6 that is coated on outside the lead 5 that comprise equidistant arrangement, the cross sectional shape of described protective layer 6 are by rectangle 61 with along equidistant a plurality of circular 62 compound patterns of arranging that combined of described rectangle 61 length directions; The diameter of described each circle 62 is greater than the width of rectangle 61; Described each circle 62 and a corresponding lead 5 concentric settings.Described protective layer 6 is fluoroplastics protective layers 6, and the shape of described protective layer 6 left and right sides ends all is circular.

Present embodiment has designs simplification, can adopt the direct processing and manufacturing of injection molding, thereby has lower-cost advantage.

Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to execution mode of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all execution modes.And these belong to conspicuous variation or the change that connotation of the present utility model extends out and still belong to protection range of the present utility model.

Claims
