As a further improvement, the length direction of the stiffening plate along compliant conductive plate is attached on compliant conductive plate.

As a further improvement, one end of the stiffening plate from compliant conductive plate is sticked to opposite other end.

As a further improvement, the stiffening plate has several, and several stiffening plate intervals are attached at the phase of compliant conductive plate To on both ends.

As a further improvement, the stiffening plate is attached in the upper and lower surface of compliant conductive plate.

As a further improvement, the stiffening plate is made of PI, PET, PP, gum or resin material.

As a further improvement, the compliant conductive plate is using FPC or FFC.

As a further improvement, a connecting pin of the compliant conductive plate is the soft or hard knot that soft board and hardboard are combined into Plywood, the conduction golden finger are set on Rigid Flex.

As a further improvement, the insulation serving is together with compliant conductive plate and reinforcement plate injection moulding.

As a further improvement, the both sides of the edge of the stiffening plate protrude out to form holding parts outwardly, and the holding parts are grabbed It is located in insulation serving.

In conclusion the utility model flat cable is by the stiffening plate that is sticked in the pliable region of compliant conductive plate, i.e., Stiffening plate is located at the joint of insulation serving and compliant conductive plate and is at least partly embedded in insulation serving, so as in profit On the basis of making flat cable more frivolous with compliant conductive plate replacement electric wire, stiffening plate is utilized to strengthen compliant conductive plate Mechanical strength, effectively promote compliant conductive plate waves performance, compliant conductive plate is made to be not easily broken in bending region, and then extend The service life of flat cable.
