Rubber key for thin film keyboard

Abstract

The invention discloses a rubber key for a thin film keyboard. The rubber key comprises a key film, a rubber key part and a contact block, wherein a reinforcing rib is arranged at the outer side of the key film; the rubber key part is mounted at the inner side of the reinforcing rib; a flow guide groove is formed in the outer side of the rubber key part; a positioning block is arranged at a part,close to the inner side of the key film, of the outer side of the rubber key part; a rubber button is arranged at the middle position of the rubber key part; a button lug boss is arranged at the outerside of the rubber button; a fatigue rubber ring and a key reinforcing rib are arranged between the rubber button and the rubber key part; the thickness of a connecting part of the key is increased,the toughness and the strength are increased when the key moves, and feedback force is improved when the key moves, so that the hand feeling of the key is better; an internal octagonal rubber block isinternally provided with an octagonal hollow circular truncated cone, so that the button obtains a higher restoring force in a deformation process; furthermore, the position of a contact piece is lower and a key travel is reduced, so that the deformation amount of rubber is reduced, and the service life of the key is prolonged.

Description

technical field [0001] The invention belongs to the technical field of rubber keys, and in particular relates to a rubber key for a membrane keyboard. Background technique [0002] Button glue, the product is translucent, mainly used for remote control buttons, telephone buttons, bracelets and miscellaneous items, etc. Membrane keyboard is an example of membrane switch category. Membrane switches with more buttons and neatly arranged, people are used to Call it a membrane keyboard. [0003] After the original membrane keyboard is used for a long time, due to the repeated stretching and recovery deformation of the rubber, the joint between the rubber button and the rubber plate is prone to rubber fatigue and aging, and cracks may appear or lose elasticity, making the key feel worse. , or even malfunction, affecting normal use. Contents of the invention [0004] The object of the present invention is to provide a kind of rubber button for membrane keyboard, to solve the pr...
