The invention relates to the technical field of piezoelectric sensors, in particular to a pressing cap of a T-shaped piezoelectric sensor. The pressing cap comprises a base; a containing groove is formed in the base, a placing platform is arranged in the containing groove, an elastic contact is arranged on the carrying platform, and an FPC assembly and a sensing chip electrically connected with the FPC assembly are arranged on the upper surface of the elastic contact; and a removable top cover plate is arranged on the base, a pressing part convex outwards is arranged on the top cover plate, afirst abutting-pressing convex block and a second abutting-pressing convex block are arranged under the top cover plate in a spacing mode, the first abutting-pressing convex block is arranged to correspond to the placing platform, and the top cover plate is integrally formed with the pressing part, the first abutting-pressing convex block and the second abutting-pressing convex block. The pressingcap achieves a good protection effect, is high in acting force transmission efficiency, is designed by adopting an integral forming process, effectively reduces the manufacturing and producing cost and prolongs the service life.
Description
technical field [0001] The invention relates to the technical field of piezoelectric sensors, in particular to a pressing cap of a T-shaped piezoelectric sensor. Background technique [0002] With the rapid development of science and technology, electronic products are becoming more and more intelligent. At present, most electronic products such as mobile phones, computers, and household appliances use piezoelectric sensors. Piezoelectric sensors include touch screens and buttons for auxiliary adjustment functions. However, the structure of the existing buttons is relatively complicated, and there are many parts required for assembly and connection. transmit electrical signals. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art and provide a pressing cap for a T-shaped piezoelectric sensor, which has a good protective effect and high force transmission efficiency. It is designed by an integral molding p...
