Abstract

The utility model relates to a USB (Universal Serial Bus) disk. The USB disk comprises a shell, a chip and an USB interface, wherein the two ends of the shell are bamboo tubes, a spring is connected at the middle of the shell, and the chip inside the shell is closely articulated with the tails of the bamboo tubes of the shell; and the USB interface is cylindrical, the port of the USB interface is connected with an insulator, and the internal and external walls of the USB interface respectively serve as an internal contact pole and an external contact pole. According to the USB disk, the structure is simple, the use is convenient, contacts of the chip can be protected through the function of the spring of the shell, the problem that a protecting cover of the traditional USB disk easily falls off is solved, and the concept of environmental protection is better embodied through making the shell from bamboo tubes; and due to a circular jack, the defect that the front and back faces of the traditional USB disk are difficultly plugged is overcome, and the distinguish between the front and back faces is not required when the circular jack is connected with a circular USB interface of an external electronic device, so that the use process becomes simpler, more convenient and faster.

Description

A kind of USB flash disk

Technical field

The present invention relates to a kind of USB flash disk, belong to the electronic data storage facilities.

Background technology

USB flash disk is small and exquisite because of it, the information storage amount is large, easy to carry; being subject to increasing people likes; but existing USB flash disk shell mostly is and is flat rectangular shape; the USB interface place of USB flash disk is provided with over cap; the greatest drawback that exists is that over cap is easily lost; USB flash disk docks easy positive and negative wrong with computer, especially in the situation that the weak insertion computer of light can misplug the direction into mistake.

The utility model content

The utility model discloses a kind of USB flash disk, can overcome defects, although there is not over cap, can protect the USB flash disk interface, and no longer need centering, reverse side with the external electronic device grafting, simple in structure, easy to use, and environmental protection.

The technical solution of the utility model is achieved in that

A kind of USB flash disk comprises housing, chip and USB interface, and described housing two ends are thick bamboo tube, middle linking springs, inside chip and the tight interlock of housing thick bamboo tube afterbody; Described USB interface is cylindrical, and port connects insulator, and USB interface place inside and outside wall is respectively interior contact limit and outer contacting limit.

The utility model is simple in structure, easy to use, and the spring function of shell can be protected chip contact, solves the shortcoming that the conventional USB flash drive over cap easily falls, and does shell with thick bamboo tube and has more standby environmental protection concept; And round jack has solved the difficult defective of inserting of conventional USB flash drive tow sides, is connected with the circular USB interface of external electronic device, no longer needs centering, reverse side, allows use procedure become more simple and convenient.

Fig. 1 is that the utility model uses the pre-structure schematic diagram;

Fig. 2 is that the utility model uses the status architecture schematic diagram.

1, housing, 2, spring, 3, interior contact limit, 4, the outer contacting limit, 5, insulator.

Embodiment

Below in conjunction with drawings and Examples the utility model is elaborated.

As shown in Figure 1: a kind of USB flash disk, comprise housing 1, chip and USB interface, described housing two ends are thick bamboo tube, middle linking springs 2, inside chip and the tight interlock of housing 1 thick bamboo tube afterbody; Under not use state, USB interface embeds in the thick bamboo tube, and a ports having insulator exposes outside the cylinder; The use state as shown in Figure 2, USB interface is cylindrical, port connects insulator 5, interior contact limit 3 and the outer contacting limit 4 of USB interface place inside and outside wall are exposed outside the cylinder.

When the USB flash disk interventional instrument, the spring stress of housing is compact toward retrude, allows the USB socket contact the USB interface of external equipment; When extracting USB flash disk, spring resiles, the protection chip; The spring function of housing can be protected the inside and outside contact limit of USB flash disk, solves the shortcoming that the conventional USB flash drive over cap easily falls.The round socket of the utility model design has solved the difficult defective of inserting of conventional USB flash drive tow sides, is connected with the circular USB interface of computer or other external equipment, allows use procedure become more simple and convenient.Use thick bamboo tube to do the USB flash disk housing, more embody environmental protection concept.

Claims

1. a USB flash disk comprises housing, chip and USB interface, it is characterized in that: described housing two ends are thick bamboo tube, middle linking springs, inside chip and the tight interlock of housing thick bamboo tube afterbody; Described USB interface is cylindrical, and port connects insulator, and USB interface place inside and outside wall is respectively interior contact limit and outer contacting limit.
