Button structure assembly

Abstract

The invention relates to a button structure assembly, aimed at addressing high cost of single-body water proof and dust-proof design that is adopted by current buttons. A circuit board where buttons are placed is coated with a back cover sheet metal thereon. The back cover sheet metal is provided with a shallow groove thereon. The shallow groove is provided with hole slots at positions corresponding to each button body of the circuit board. The shallow groove is provided with a silica gel pad therein for covering and isolating the hole slots. The outer circumference of the top surface of the back cover sheet metal is provided with a water-proof pad, and then a surface sheet metal is covered on the top surface of the back cover plate gold and is locked and secured. The surface sheet metal is provided with plural holes in sets for placing each button pedestal and each button. According to the invention, the water-proof pad between the surface plate gold and the back cover plate gold and the silica gel pad inside the shallow groove achieve the effects of completely isolating buttons and button bodies of the circuit board, and achieve the effects of complete water-resistance and dust-resistance without compromising the control function of the button body, prevent the circuit board from having breakdowns due to intrusion of water or dust through button slits. Also, the button structure assembly is easy to assembly, can effectively reduce production cost, and has industrial values.

Description

technical field [0001] The present invention relates to a button structure assembly, in particular to a structure improvement design aimed at realizing the waterproof and dustproof function of the button, through a waterproof gasket and a silicone gasket made between the surface plate gold and the back cover plate gold , it can achieve a comprehensive waterproof and dustproof effect, and at the same time, it is easier to assemble and can reduce production costs, thereby endowing it with excellent industrial utilization value. Background technique [0002] At present, general processing machinery or automatic control equipment often use buttons to input data and set related values.

Problems solved by technology

[0002] At present, general processing machinery or automatic control equipment often use buttons to input data and set related values. In order to prevent water stains, sweat stains and dust from entering the internal circuit board, resulting in poor sensitivity or failure of the buttons, the button Membrane keys may be used in the design, but such membrane keys are often damaged under the contact friction of repeated operations, and their practicability and durability are obviously not as good as mechanical keys.

[0003] However, the existing mechanical buttons are assembled on a preset substrate by adopting a single unit. In order to obtain the flexibility of pressing the button, there is usually a slight gap between the button and the substrate, so as to avoid the button from being stuck due to friction. However, the existence of these gaps provides a path for water stains and dust intrusion, which also leads to the problem of high failure rate of mechanical keys. less relevant design

[0004] Considering the waterproof and dustproof structure of the existing buttons, it is usually directly integrated and designed inside the single button to obtain the expected waterproof and dustproof performance. The complexity of the button structure, although the expected function can be achieved, but the difficulty of assembly due to the complex structure will increase the overall assembly cost, which is not conducive to the industrial use value. Therefore, how to achieve the waterproof and waterproof function of the button In addition to the dust function, it can also take into account the reduction of its overall assembly cost, so it has become the goal of the present invention.
