Telescopic structure of portable U disk

Abstract

The invention relates to a telescopic structure of a portable U disk. The telescopic structure mainly comprises an upper shell, a lower shell, a circuit device carrier and a USB circuit device, wherein the USB circuit device is inlaid in the circuit device carrier, the USB circuit device and the circuit device carrier are arranged together in the lower shell body, and the upper shell body directlyfixedly covers the lower shell body in a matching way, thereby forming the portable U disk; the circuit device carrier and the USB circuit device arranged thereon can still be positioned in the upperand the lower shell bodies to be pushed to make forward and rearward motion of displacement, so a USB adapter on the front end of the USB circuit device is kept in the state of fixedly extending outfrom the front ends of the upper and the lower shell bodies or is kept in the state of fixedly retracting into the upper and the lower shells.

Description

technical field [0001] The invention relates to a portable U disk telescopic structure, in particular to provide a portable U disk telescopic structure that is easy to assemble and combine, has a relatively simple structure, and is very convenient and smooth for a USB joint telescoping action. Background technique [0002] According to the relevant retractable portable U disk disclosed by the Taiwan patent documents, there are at least the announcement No. M282294 and the announcement No. M326204. After investigation, the shell design of the former telescopic portable USB flash drive is quite complicated. In addition to dividing the shell into two parts and forming them separately, another circuit device carrier has to be installed to install the memory circuit device. Only when the high frequency of the circuit carrier is fused in the middle of the two shells can the assembly work be completed, which wastes a lot of manufacturing process and labor costs, so that the manufac...

AI Technical Summary

Problems solved by technology

After investigation, the shell design of the former telescopic portable USB flash drive is quite complicated. In addition to dividing the shell into two parts and forming them separately, another circuit device carrier has to be installed to install the memory circuit device. Only when the high frequency of the circuit carrier is fused in the middle of the two shells can the assembly work be completed, which wastes a lot of manufacturing process and labor costs, making it impossible to reduce the manufacturing cost

And the announcement No. M326204 that the late entrants improved again, the latter retractable portable USB flash drive, its structure has been improved and is relatively simple, but it is still divided into: an outer shell unit, an inner sliding unit and a closed unit, and is It is still quite inconvenient to manufacture the pressing body that controls the telescopic action and the internal sliding unit, that is, the memory unit and its joints; at the same time, the additional closed unit is plugged into the outer shell unit At the end of the joints, it is still necessary to perform fusion action with high frequency to ensure that they are firmly combined with each other. Otherwise, even if they are bonded with adhesive or glue, they are still prone to loosening.

And the production cost it can reduce is also very limited
