Dustproof earphone hole

Abstract

The invention relates to a dustproof earphone hole which comprises a conductive cylinder and an insulated rubber ring. A sealing shaft is mounted in the axis of the conductive cylinder. The sealing shaft penetrates through a base board. A baffle board is fixed at the lower end of the sealing shaft. The baffle board is connected with the base board through an extension spring. A sealing board is fixed at the upper end of the sealing shaft. The dimension of the sealing board matches the hole diameter of a downmost-layer conductive cylinder. Except for the downmost-layer conductive cylinder, each conductive cylinder is internally provided with a sealing ring slidably. The inner diameter of each sealing ring is same with that of the adjacent conductive cylinder below. The inner ring surface of each sealing ring is provided with spacing fasteners. The top end of a topmost conductive cylinder is provided with a spacing buckle. The sealing ring, the sealing board and the sealing shaft are made of a ferromagnetic material. Insulating layers are applied on the surfaces of the sealing ring, the sealing board and the sealing shaft. The dustproof earphone hole has advantages of realizing exquisite structure, effectively separating dust, preventing entering of water drops, and greatly improving waterproof safety effect of electronic products.

Description

technical field [0001] The invention relates to an electronic product component, in particular, an earphone hole. Background technique [0002] The earphone jack can be said to be one of the necessary components of electronic products; the current mainstream earphones are multi-segment earphone columns, so the corresponding earphone jack is divided into multiple conductive cylinders inside, and insulating rubber is embedded between adjacent conductive cylinders to prevent Cut off the short circuit between the electric tubes; but in the process of use, it is inevitable that dust will adhere to the headphone jack, and even water droplets will be splashed, causing a short circuit of the internal electronic components, which will damage the headphone jack module; It brings great inconvenience; especially when using electronic products such as mobile phones, the water short circuit at the headphone jack may burn out the entire mobile phone, causing greater economic losses to us...
