Abstract

This utility model provides the FFC of a kind of conductor variable format, including, upper plastic layer, lower plastic layer, it is located at conductor layer therebetween, being provided with complex root wire in described conductor layer, the two ends of described conductor layer are positioned at outside plastic layer, and the both ends of each wire in described conductor layer are flat, the interlude cross sectional shape of each wire is rounded, and the interlude of described wire is between upper plastic layer and lower plastic layer.So that the distance between adjacent two wires becomes big, beneficially FFC line status bar operation.

Description

A kind of FFC of conductor variable format

Technical field

This utility model flexible flat cable technical field, its interior wire interlude cross sectional shape arranged a kind of The FFC of rounded conductor variable format.

Background technology

The abbreviation of FFC i.e. Flexible Flat Cable, Chinese is flexible flat cable, also referred to as winding displacement, is widely used in In each electronic product such as computer, printer.Wire both ends in existing FFC conductor layer, i.e. expose at two plastic outer layers Outside part and conductor cross-section shape between two plastic outer layers be flat square or in irregular shape, Thus cause the less point bar operation being unfavorable for FFC of the distance between adjacent two PIN；And because of flat on wire, patch The regulation of characteristic impedance it is unfavorable for after auxiliary material.

Utility model content

In place of overcoming the deficiencies in the prior art, the purpose of this utility model is to provide the wire in a kind of conductor layer Interlude cross sectional shape is the FFC of conductor variable format circular, that two ends are flat, so that between adjacent two wires Distance becomes big, beneficially FFC line status bar operation.

For achieving the above object, the technical solution adopted in the utility model is: the FFC of a kind of conductor variable format, including, Upper plastic layer, lower plastic layer, be located at conductor layer therebetween, is provided with complex root wire, described conductor layer in described conductor layer Two ends be positioned at outside plastic layer, the both ends of each wire in described conductor layer are flat, the centre of each wire Section cross sectional shape is rounded, and the interlude of described wire is between upper plastic layer and lower plastic layer.

Advantageous Effects: the both ends of each wire in described conductor layer are flat, the interlude of each wire Cross sectional shape is rounded, so that the distance between adjacent two wires becomes big, and beneficially FFC line status bar operation；And, lead The intermediate stage of line pastes relatively thin material, characteristic impedance can be controlled at about 100 Ω.

Detailed description of the invention

In order to make those skilled in the art be more fully understood that this New Scheme, below in conjunction with the accompanying drawings with embodiment to this Utility model is described in further detail.

As Figure 1-4, the FFC of conductor variable format includes, upper plastic layer 1, lower plastic layer 2, is located at therebetween Conductor layer 3, is provided with complex root wire 301 in described conductor layer, the two ends of described conductor layer are positioned at outside plastic layer 1, i.e. lead The end of body layer 3 is exposed outside.

The both ends 301a of each wire in described conductor layer 3 is flat, the interlude 301b cross section of each wire Shape is rounded, and the interlude 301b of described wire is between upper plastic layer 1 and lower plastic layer 2.

Although depicting this utility model by embodiment to create, it will be appreciated by the skilled addressee that this utility model There are many deformation and change without deviating from spirit of the present utility model, it is desirable to appended claim includes these deformation and change Without deviating from spirit of the present utility model.

Claims

1. a FFC for conductor variable format, including, upper plastic layer, lower plastic layer, it is located at conductor layer therebetween, described Being provided with complex root wire in conductor layer, the two ends of described conductor layer are positioned at outside plastic layer, it is characterised in that described conductor layer The both ends of interior each wire are flat, and the interlude cross sectional shape of each wire is rounded, the interlude of described wire Between upper plastic layer and lower plastic layer.
