Waterproof and brightened silicone key of smart remote control

Abstract

The invention discloses a waterproof and brightened silicone key of a smart remote control. The silicon key comprises a key base body and a plurality of keys protruding towards the outer side. The lower side of the key base body is provided with a PCB circuit board. A plurality of welding clearance regions protruding towards the upper side and a plurality of positioning columns protruding towardsthe lower side are formed between the keys. The welding clearance regions are directly facing the component soldered on the PCB circuit board. Positioning holes are arranged in the PCB circuit board,the positioning columns are inserted into the positioning holes, and heads of the positioning columns are in the enclosed state. The welding clearance regions are formed to replace openings to avoid high temperature generated by the welding, and the positioning columns with the enclosed heads are formed to replace the mode of inserting positioning pins in opened holes. The functional areas of thesilicone keys form a whole, and the entire silicone key does not have hole positions penetrating through the upper side and the lower side of the key base body, so the silicone key has good waterproofperformance. The PCB circuit board disposed under the silicone key is not likely to suffer from short circuit or damage due to an accidental water damage of the remote control.

Description

technical field [0001] The invention relates to the technical field of remote controls, in particular to a waterproof and brightened intelligent remote control silicone button. Background technique [0002] The silicone button of the smart remote controller is inlaid on the shell of the remote controller, the button passes through the key hole provided on the shell and protrudes from the upper surface of the shell, and a PCB circuit board is arranged under the silicone button. The user presses the button, and the button triggers the PCB circuit board to complete the remote control function. [0003] Generally, a plurality of related electronic components need to be soldered on the PCB circuit board, so the existing silicone buttons are generally provided with openings in corresponding places, so as to avoid the high temperature generated by welding from destroying the silicone close to the soldering point. Moreover, in order to realize the relative position fixation of the ...

Problems solved by technology

[0004] As a result, the existing silicone keys have poor waterproof performance. When the remote control shell accidentally enters water, the water will easily flow into the silicone keys through the key holes, and then flow into the PCB circuit through the holes or openings on the silicone keys. board, and then there is a short circuit or the phenomenon of burning out the PCB circuit board
