AI Technical Summary

Technical Problem

The existing keyboard key modules have insufficient shortcomings when preventing liquid from entering the film circuit board. External liquid can still flow in through the air escape hole or component gaps, resulting in damage to the conduction points, solder joints and components, thereby causing the function of the film circuit board to fail.

Method used

By providing a structure covering the air escape hole on the elastic element and a plurality of merra plates are arranged on the film circuit board for adhesive connection, a closed space is formed to prevent liquid from entering.

Benefits of technology

Effectively prevent liquid from entering the film circuit board, avoid damage, and ensure the normal function and feel of the keyboard.

Abstract

The utility model discloses an anti-liquid key module and keyboard, including keycap, scissors foot, elastic element, base plate, film circuit board, elastic element is used for abutting on the conducting point on film circuit board, the film circuit board is also provided with the vent hole, elastic element is provided on the vent hole and can cover the vent hole, and the elastic element is provided on the film circuit board and can cover the vent hole. The periphery of the bottom of the elastic element is closely attached to the circuit board. The bottom of the film circuit board is provided with a first Mylar board, and the first Mylar board is provided with an air escape channel. A second Mylar board is arranged between the thin film circuit board and the bottom board, and the second Mylar board is connected with the binding face of the bottom of the bottom board and the binding face of the top of the thin film circuit board in an adhesive mode. The top of the bottom plate is further provided with a third mylar plate, the third mylar plate is connected with the bottom plate in an adhesive mode, the middle of the third mylar plate is provided with a through hole matched with the elastic element, and the through hole is connected with the contact portion of the elastic element in an adhesive mode. According to the utility model, the film circuit board is effectively prevented from being eroded by liquid through the modification of the gas escape structure and the stacking of a plurality of mylar boards.
