Problems solved by technology

[0002] SD cards are widely used in portable devices, such as digital cameras, personal digital assistants, multimedia players, smart phones, etc. At present, SD cards in portable devices rarely consider their waterproof effect, and once a portable device with an SD card is accidentally inserted, it will If water enters or falls into water, the chip of the SD card can easily enter the water, causing the SD card to fail or the data stored in the SD card to be lost, resulting in irreparable consequences
In addition, due to the small size of the SD card, this also increases the technical difficulty of making a waterproof SD card.

Embodiment Construction

[0024] The present invention will be further described below with reference to the accompanying drawings and in combination with preferred embodiments.

[0025] The method for making the SD card with waterproof function of the present invention mainly includes three steps: prepare the SD card substrate with a circle of grooves at the end; apply a layer of glue in the groove; put the SD card substrate into the injection mold, A circle of silicone boss is injection-molded at the groove to achieve an interference fit with the SD card slot, that is, to form a waterproof SD card.

[0026] In a preferred embodiment of the present invention, when making the SD card base, a plurality of glue overflow holes are provided in a circle of grooves, and these glue overflow holes are arranged equidistantly with a distance of 1.5-2.0 mm. The glue overflow hole can allow the excess glue in the groove to flow out from there, and avoid allowing the glue to accumulate in the groove or even overflo...

Abstract

The invention discloses an SD (secure digital) card with a waterproofing function and a manufacturing method of the SD card. The manufacturing method of the SD card includes the steps of S1: preparing to form an SD card body, in a form of a circle of slot, at the tail end; S2: coating a layer of glue in the slot; S3: placing the SD card body into an injection mold, and obtaining a circle of silicon boss at the position of the slot by means of injection molding so as to form the SD card with the waterproof function. The SD card manufacturing method has the advantages that the SD card with the waterproofing function is formed by shaping a circle of silicon boss, integrated with the SD card body, at the tail end of the SD card body, interference fit is formed between the silicon boss and an SD slot when the SD card is inserted into the SD slot, the waterproof function and a dustproofing function are realized, a chip of the SD card is protected, and safety of the SD card is enhanced.

Description

technical field [0001] The invention relates to the field of storage devices, in particular to a waterproof SD card and a manufacturing method thereof. Background technique [0002] SD cards are widely used in portable devices, such as digital cameras, personal digital assistants, multimedia players, smart phones, etc. At present, SD cards in portable devices rarely consider their waterproof effect, and once a portable device with an SD card is accidentally inserted, it will If water enters or falls into water, the chip of the SD card can easily enter the water, causing the SD card to fail or the data stored in the SD card to be lost, resulting in irreparable consequences. In addition, due to the small size of the SD card, this also increases the technical difficulty of making a waterproof SD card. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a method for making a waterproof SD card. A ring of ...
