Structure improvement of the flash drive

The creation system provides a structure improvement of the flash drive, especially the rear portion of the upper surface of the casing is formed with a bulging portion, and is pushed into the casing by the susceptor with the circuit module, so that the pedestal can be pushed The pressing portion smoothly slides into the casing through the arching portion to facilitate assembly and maintain the appearance and stability of positioning in the casing.

According to the current rapid growth of electronic technology, the computer type has evolved from a desktop computer into a small-sized and portable notebook computer, and it is widely used in all corners of society, and has a strong computing power and fast speed. And the small size of the direction, because the computer and notebook computer need to use a hard disk with a large storage capacity when dealing with huge data calculations, so the hard disk of the computer and the notebook computer will be set inside, so that it can be added The capacity of the data storage, but it is not conducive to the user because of its large size, and with the popularity of the universal serial bus (USB) interface specification and the price reduction of the flash memory, it has both large capacity and good compatibility. The USB Flash Disk is widely used for data transmission between different computers and notebook computers and flash drives. It has the features of large capacity, plug and play, compact size and convenient portability.

However, with the generation of electronic technology alternating, the variety of electronic devices has increased, and there are also a variety of connection interfaces for users to choose, so the pen drive is suitable for different rules. Under the premise of the connection interface of the grid, it is necessary to have sufficient applicability, so that the electronic device equipped with the connector of different specifications can be connected to the connector of the computer or the notebook computer through the flash drive to synchronize or access the data. Generally, the circuit board is provided with a storage module inside the casing, and the inner lining member is coupled to the circuit board, so that the lining member can be pushed and the connection interface at the front of the circuit board protrudes from the casing. The outside of the body is inserted into the slot of the same interface specification of the electronic device, but the broken hole formed on the upper surface of the housing extends to the rear to form an unclosed state, so that the lining member and the housing are assembled. The protruding block on the upper surface can be smoothly pushed into the casing through the hole to complete the assembly, but the design of the hole structure without the closed casing is not complete and unattractive, and will affect the whole. The structural strength, when the user accidentally drops the flash drive to the ground or the impact of external force collision, it may cause the lining member to withdraw or detach backward toward the hole, or even damage the storage module structure. Thus ramifications of failure function, that is, for those who are engaged in this industry desperately wants to redesign the key lies.

Therefore, in view of the above-mentioned problems and shortcomings, the new creators have collected and reviewed relevant materials through various evaluations and considerations, and have used the trial and modification of many years of R&D experience in this industry to improve the structure of such portable discs. A new type is born.

The base portion 311 of the main body 31 is elastically deformed when the pressing portion 32 is depressed; and the base portion 311 of the main body 31 is located at the front of the second dissection groove 3111, and is a tooth-shaped first protruding buckle 331 respectively provided with the locking portion 33, and A tooth-shaped second protrusion 332 having a height slightly larger than the first protrusion 331 is disposed at a distance from the rear side of the first protrusion 331 to the side of the pressing portion 32, and the wall of the positioning space 30 on the inner side of the two side plates 312 of the body 31 is A plurality of limiting slots 3121 are defined, and are arranged at an edge of the side edge of the side plate 312. The plurality of slots 3122 are spaced apart from each other, and the front edge of each of the slots 3122 extends outwardly and rearwardly and horizontally with a floating elastic piece 3123; further, the base portion 311 of the body 31 and the rear side plate 312 are provided with a convex fitting. Part 34.

When the present invention is assembled, the body 31 of the pedestal base 3 is first coupled to the circuit board 21 of the circuit module 2, and the circuit board 21 can be embedded upward in the positioning space 30 at the opening 301 below the body 31. And the four corners of the circuit board 21 are respectively clamped in the limiting slots 3121 of the opposite side wall surfaces of the two side boards 312, and the connection interface 22 is The plug 221 extends out of the vacant slot 3131 of the front cover 313, and the push base 3 can be pushed forward into the opening 101 of the housing 1 and designed by using the arch portion 13 formed at the rear of the housing 1. The pressing portion 32 on the surface of the body 31 can smoothly slide into the accommodating space 10 of the casing 1 through the facing groove 131 of the bulging portion 13 to facilitate assembly and maintain the appearance of the body, and the pressing portion The latching portion 33 at the two sides of the latching portion 33 is displaced upwardly along the guiding surface 1411 by the first protruding latch 331 against the stopper 141 of the latching portion 14 until the first latching tab 331 passes over the stopper 141.
