Description

A kind of novel flexible wiring board

Technical field

The utility model is related to a kind of circuit board, more particularly to a kind of novel flexible wiring board.

Background technology

Under current information society, the mankind are growing day by day to the dependence of electronic product.In response to electronic product now At high speed, high-effect and light and short requirement, flexibility wiring board is gradually applied in various electronic devices, such as pen Remember this computer, mobile phone etc..But at present applied to the device for thering is repetition to bend demand（Enter mechanical arm）When upper, flexible wires The problems such as road plate still has winding, knots, and when the devices such as mechanical arm are bent, flexible circuit board often will present pair The state of folding is easy to damage the circuit in flexible circuit board, reduces flexible circuit board if repeating this state for a long time Service life.

Utility model content

The purpose of this utility model is to provide a kind of novel flexible wiring board, by the way that substrate is arranged to stretchable spiral Shape can provide the circuit on substrate and protect and substrate be made to have the function of extending and shrink, to avoid in machinery The problems such as flexible circuit board doubling, winding occurs and gives a discount when the devices such as arm are bent, extends the use of flexible circuit board Service life.

To achieve the above object, the utility model provides a kind of novel flexible wiring board, including substrate, and the substrate is Flexible material is made, and the substrate is telescopic helical form, and be electrically connected contact and patterned circuit are provided on the substrate Layer, the contact that is electrically connected are electrically connected with patterned line layer, are provided on the substrate and are electrically connected with patterned line layer Electronic component.

Compared with prior art, the beneficial effects of the utility model are, by the way that substrate is being arranged to stretchable spiral shell Shape is revolved, the circuit on substrate can be provided and protect and substrate is made to have the function of extending and shrink, to avoid in machine The problems such as flexible circuit board doubling, winding occurs and gives a discount when the devices such as tool arm are bent, extends making for flexible circuit board With the service life, the utility model can be used in the installation production of bent equipment.

Telescopic helical form sheath is arranged on the substrate as a further improvement of the utility model, it is right in this way Substrate plays the role of protection, and substrate can be followed to stretch or shrink together.

Substrate both ends are stretched out the sheath and are fixed with sheath both ends as a further improvement of the utility model, in this way Can substrate be fixed in sheath, avoid colliding with sheath because shaking in use.

The substrate maximum tension length is more than sheath maximum tension length as a further improvement of the utility model, Sheath can be made when being stretched to maximum length in this way, substrate also there are surplus is stretched, avoids substrate from being pullled bad.

It is provided with distance measurement element on the substrate as a further improvement of the utility model, ranging can be passed through in this way Element makes electronic equipment stretch the maximum tension bending amplitude that the amplitude bent does not exceed substrate.

The flexible material is polyimides as a further improvement of the utility model, can ensure that base in this way Production cost is also controlled while plate flexibility.

Described substrate one end is electrically connected with electric connector as a further improvement of the utility model, so that base Plate is in the contact that is electrically connected not enough in use, can be connect with other electronic components by electric connector.

Wherein, 1 substrate, 2 electronic components, 3 sheaths, 4 patterned line layers, 5 electric connectors, 6 are electrically connected contact.

Specific implementation mode

The utility model is further illustrated below in conjunction with the accompanying drawings：

A kind of novel flexible wiring board as shown in Figs 1-4, including substrate 1, substrate 1 are made of flexible material, and substrate 1 is Telescopic helical form is provided be electrically connected contact 6 and patterned line layer 4 on substrate 1, and be electrically connected contact 6 and patterned circuit Layer 4 is electrically connected, and the electronic component 2 being electrically connected with patterned line layer 4 is provided on substrate 1；Being arranged on substrate 1 can stretch The helical form sheath 3 of contracting；1 both ends of substrate are stretched out sheath 3 and are fixed with 3 both ends of sheath；1 maximum tension length of substrate is more than sheath 3 maximum tension length；It is provided with distance measurement element on substrate 1；Flexible material is polyimides；1 one end of substrate is electrically connected with electricity Connector 5.

When work, substrate 1 is retractable spiral shape, can meet the needs of electronic equipment bending, stretch so that substrate 1 It will not be damaged after long-time use, sheath 3 is retractable spiral shape and consistent with 1 shape of substrate, is set in base Can be that substrate 1 provides protection, the distance measurement element on substrate 1 can ensure that electronic equipment is bending the amplitude of stretching not on plate 1 More than the maximum tension length of substrate 1 and sheath 3, in this way can preferably protective substrate 1 it is injury-free；1 maximum tension of substrate Length is more than 3 maximum tension length of sheath, works as failure in this way so that the amplitude that the bending of electronic equipment stretches is more than substrate When 1 maximum tension length, before sheath 3 without damaging completely, there is time enough to cut off the power, ensures that substrate 1 will not be by Damage.

The utility model is not limited to the above embodiment, on the basis of the technical solution of the disclosure, the technology of this field According to disclosed technology contents, some of which technical characteristic can be made personnel by not needing performing creative labour It replaces and deformation, these replacements and deformation is within the protection scope of the present utility model.
