A waterproof cushion for the lower cover of the motherboard

Abstract

The invention discloses a main plate lower cover waterproof soft cushion which comprises a main plate. A lower cover is movably connected to the outer side of the main plate; a cushion body is movablyconnected to the bottom part of the lower cover; a first arch groove is formed in the top part of the cushion body; an adsorption device is arranged right under the first arch groove, and comprises asucking disc; the sucking disc is arranged on the bottom part of the first arch groove; a bolt is fixedly connected to the bottom part of the sucking disc; a second arch groove is formed in the position, close to the lower side of the first arch groove, in the cushion body; a gland is arranged in the second arch groove; the upper end of the bolt penetrates through the bottom part of the gland; asleeve and a nut are sequentially and movably connected to the outer side of the middle part of the bolt from top to bottom; a distance ring is movably connected to the bottom part of the nut; a gasket is movably connected to the bottom part of the distance ring; a first plug is arranged on the bottom part of the gasket; the outer side of the first plug is movably connected with the bottom part ofthe cushion body; a flow distribution groove is formed in the cushion body; plug holes are formed in the periphery of the cushion body; and second plugs are movably connected into the plug holes. Themain plate lower cover waterproof soft cushion provided by the invention has the advantages of convenience in replacement and difficulty in deformation when the bottom part of the cushion body is unevenly stressed.

Description

technical field [0001] The invention relates to the field of waterproof cushions, in particular to a waterproof cushion for the lower cover of a main board. Background technique [0002] With the rapid development of electronic products, integrated circuit boards are widely used in daily life; circuit boards are the core components of electronic products; in order to prevent them from being damaged by the outside world, waterproof and wear-resistant soft Pad; motherboard lower cover waterproof pad Waterproof performance is the key factor to prevent the motherboard from getting wet, once the moisture enters the mobile phone and enters the motherboard through the lower cover, it will seriously affect the performance of internal components.

Problems solved by technology

[0003] Waterproof foam is a commonly used waterproof material for cushions. In order to improve the waterproofness of foam, it is often necessary to increase the number of layers of foam and use a waterproof film as an insulating material to prevent further moisture from entering. However, this cushion is installed under the motherboard. When the cover is covered, glue is often used; this method is not convenient for secondary replacement; when the cushion is worn or broken, the cushion needs to be scraped off with a knife first, and the glue needs to be cleaned; further, The existing soft pad is prone to self-defense deformation when the force on the bottom is uneven; it directly causes the lower cover of the main board to be unable to be placed horizontally
