Flexible electrode switching device

Abstract

The invention discloses a flexible electrode switching device, and relates to the technical field of circuit board electrode switching. The device comprises a circuit board, a flexible fixing reinforcement member, a signal transmission flexible electrode, and a fixing structural member used for positioning and fixing the circuit board and the signal transmission flexible electrode. The flexible fixing reinforcing member is located between the signal transmission flexible electrode and the fixing structural member and is used for soft contact; and the circuit board is correspondingly connected with the signal transmission flexible electrode through an electrode. According to the invention, traditional sharp point contact is improved into blunt surface contact, so that the flexible circuit is not damaged while the contact area is increased, and the problem that a printed conductive material is scraped and scraped after a traditional sharp base is plugged and unplugged to cause circuit disconnection or poor contact is solved. The flexible electrode is effectively prevented from being scalded by high temperature in the welding process of rivet riveting type connection, and the flexible electrode is better protected.

Description

technical field [0001] The invention belongs to the technical field of circuit board electrode switching, in particular to a flexible electrode switching device. Background technique [0002] With the continuous development of circuit board processing technology, thin film (Membrane) circuit boards have been widely used in key control panels and sensors of industrial control and various household appliances due to their advantages of lightness, flexibility, and low cost. With the rapid development of flexible electronics technology, large-area, flexible and high-performance flexible sensors have become one of the core key technologies supporting the development of the flexible electronics industry chain. At present, one of the key difficulties in realizing the industrial application of flexible sensors is the ( Signal transmission) Stable and reliable connection between flexible electrodes and non-flexible acquisition circuits. [0003] At present, the transfer methods betw...

Problems solved by technology

[0004] (1) Riveting of rivets: One end of the rivet is riveted on the flexible signal transmission electrode, and the flexible electrode is fixed and electrically connected through the rivet tip, and the other end is connected to the acquisition circuit by welding or plugging and unplugging. Integrity of the substrate, low efficiency and risk of poor contact of the rivets with the flexible signal transmission electrodes

[0005] (2) FFC / FPC connector: insert the flexible signal transmission electrode into the rigid FFC / FPC wire seat, and fix the point contact connection between the flexible signal transmission electrode and the rigid FFC / FPC wire seat through the drawer in-out type or the up and down cover type. Connection method Since the flexible signal transmission electrode and the rigid FFC / FPC wire holder are connected by point contact, there is no force to pull, and the flexible signal transmission electrode is easily scratched by the sharp wire holder on the FFC / FPC. Conductive materials are easily scratched off, causing circuit breaks or poor contact

[0006] (3) Conductive glue connection: The flexible signal transmission electrode is bonded to the line in the acquisition circuit through conductive glue to realize electrical connection. This connection method has problems of poor firmness and poor reliability.
