Description

A U disk with improved structure

technical field

The utility model relates to a U-disk, which belongs to mobile access equipment, in particular to a U-disk with an improved structure, which is especially suitable for notebook computers.

Background technique

U disk is the abbreviation of USB disk, also known as flash disk, which is a mobile access device connected to a computer through a USB interface for data access. At present, the U disk generally includes three parts: the shell, the USB interface and the PCB body. The USB interface and the PCB body are usually welded together and placed inside the shell. cover to avoid damage to the USB connector. When using, just plug the U disk into the USB socket of the computer. It is small in size, easy to carry, large in storage capacity, fast in reading speed and cheap in price, so it has been widely used in many fields.

With the continuous development of social economy, modern people are more and more pursuing personalization and personalized consumption. Therefore, the appearance, style and color of USB flash drives on the market are ever-changing. But various appearance styles have also caused certain troubles to people's use when satisfying people's individual requirements. Due to the different sizes of the U disk shell, it may have little effect when it is plugged into a desktop computer, but it is limited when plugged into a notebook computer, because the thickness of the notebook computer is relatively thin, and various parts and sockets are highly concentrated. , the larger U disk may be inconvenient when plugged in or affect the normal use of other sockets, thus limiting the scope of use of these U disks; on the other hand, some people use data extension cables to eliminate the above restrictions when using , but the data extension cable should be prepared at all times, causing inconvenience to carry and use.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings and deficiencies in the prior art, and provide a new type of U disk with simple structure and unlimited volume, which is especially suitable for notebook computers.

In order to achieve the above object, the utility model is realized according to the following technical solutions:

A U disk with an improved structure includes a housing, a USB interface and a PCB body, the USB interface is placed outside the housing, the PCB body is placed inside the housing, and the USB interface is connected to the PCB body by an external cable; the outer bottom of the housing is set There is a USB interface accommodating groove, and the accommodating groove is provided with a lock switch, which includes an elastic clip and a projection which is arranged on the elastic clip and buckled with the USB interface. In the utility model, the USB interface is separately arranged on the outside of the housing, and a USB interface accommodation groove is provided on the housing for storing the USB interface. The volume size can be unlimited, and it is also suitable for notebook computers, thereby expanding the use range of the U disk.

The bottom of the accommodating tank is provided with an elastic pressing piece which tends to be inclined upward. The elastic pressing piece has an elastic force tending to tilt upward. When the locking switch is opened, the USB interface placed in the USB interface accommodation groove can automatically pop out of the accommodation groove under the elastic force of the elastic pressing piece, which is convenient for use.

The above-mentioned elastic clip extends outwards to define a pressing portion. The function of the pressing part is to facilitate the user to open the locking switch, and the locking switch can be opened by simply pressing the pressing part lightly.

The above-mentioned protrusion is provided with an inclined guide surface. The role of the guide surface is to facilitate the pressing of the USB interface into the accommodation slot. When the USB interface is pressed into the accommodation slot after the U disk is used, the USB interface slides along the inclined guide surface and squeezes the lock switch at the same time, which saves labor and has a certain protection for the USB interface. effect.

A circular protrusion is provided at the tail end of the above-mentioned elastic pressing piece. When the USB interface is placed in the accommodating groove, due to the existence of the round protrusion, the elastic pressing piece will be further squeezed, thereby increasing the elastic force, which is more conducive to the automatic ejection of the USB interface.

The tail end of the above-mentioned USB interface is provided with an insulating handle. The insulating handheld part mainly provides a handshake point for the user, so that the user can plug the USB interface into the USB socket of the computer.

Fibers are arranged inside the above-mentioned external cables. The function of the fiber is to increase the bending resistance of the external cable and ensure the normal operation of the external cable.

Compared with the prior art, the utility model has simple structure, unlimited appearance style and volume size, and is especially suitable for notebook computers, so that the appearance design of the U disk is more diversified and personalized, and meets the different requirements of modern people.

In order to understand the utility model more clearly, the specific implementation of the utility model will be described below in conjunction with the accompanying drawings.

Detailed ways

As shown in Figures 1 and 2, the utility model is a U disk with an improved structure, which includes a housing 1, a USB interface 2 and a PCB body (not shown in the figure). The PCB body is placed inside the housing 1; the USB interface 2 is placed outside the housing 1, and an insulating hand-held part 21 is provided at its tail end; the PCB body and the USB interface 2 are electrically connected through an external cable 3, and the external cable 3 is provided with a There are fibers to increase the bending resistance of the external cables. The outer bottom of the housing 1 is provided with a USB interface accommodating groove 11, whose shape and size are compatible with the USB interface, just for the USB interface 2 to be placed in.

As shown in Figures 2-4, the accommodating groove 11 is provided with a locking switch 12, which includes an elastic clip 121 arranged on the side of the accommodating groove, and an elastic clip 121 which is arranged on the elastic clip and can be buckled with the USB interface. bump 122 . One end of the elastic clip 121 extends outwards to form a pressing portion 123 , and the surface of the pressing portion 123 is provided with concavo-convex curves; the outer surface of the protrusion 122 is an inclined guiding surface.

An elastic pressing piece 13 inclined upwards is provided at the bottom of the accommodating groove 11 , and a circular protrusion 131 is provided at the end of the elastic pressing piece 13 . Because the elastic pressing piece 131 has an elastic force that tends to tilt upward, when the above-mentioned locking switch 12 is opened, the USB interface placed in the accommodation groove can automatically pop out of the accommodation groove under the elastic force of the elastic pressing piece 13; With the existence of the circular protrusion 131, the elastic pressing piece is further squeezed when the USB interface is pressed in, and the deformation of the elastic pressing piece is greater, increasing the elastic force, which is more conducive to the automatic ejection of the USB interface.

When you need to use the U disk to access data, you only need to press the pressing part lightly, the elastic clip will open slightly outwards, the protrusion on the elastic clip will leave the USB interface, and the USB interface will lose the buckle function of the protrusion. Under the action of the elastic force of the pressing sheet, the accommodating slot is automatically ejected, and then the USB interface is plugged into the USB socket of the computer to be used. When the U disk is used up, just gently press the USB interface into the accommodating groove along the guide surface of the projection and use the projection to clamp the USB interface to re-store the USB interface in the accommodating groove, which is simple and convenient.

The utility model is not limited to the above-mentioned embodiment, if the various changes or modifications of the utility model do not depart from the spirit and scope of the utility model, if these changes and modifications belong to the claims of the utility model and within the equivalent technical scope, Then the utility model is also intended to include these modifications and variations.
