Description

Novel USB interface and USB plug

Technical Field

The utility model relates to a USB interface and USB plug.

Background

USB is one of the important ways for computers to transfer data to and from external storage devices. When a USB plug (e.g., a USB disk, a USB data line, etc.) is inserted into a USB interface of a computer, if the direction of the USB plug is wrong, an insert core of the USB plug collides with an inner core of the USB interface, so that the USB plug cannot be inserted into the USB interface of the computer, and at this time, the direction of the USB plug needs to be turned. Statistically, this occurs with a probability of about 50%. Frequent and violent collisions can cause the plug core of the USB plug and the inner core of the USB interface to be damaged and difficult to repair. For a computer, the number of the equipped USB interfaces is extremely limited, and for a storage device, the damage of the plug is almost equal to the loss of all the stored data. Therefore, it is necessary to design an easy-to-insert USB interface and plug.

Detailed Description

Example 1

Fig. 1 shows a schematic structural diagram of a novel USB interface, which includes a fixed frame 1 and an inner core 2. The two sides of the fixed frame 1 are provided with inward bent elastic sheets 11, and the elastic sheets 11 are used for positioning an inserted USB plug. The opening side of the fixed frame 1 is provided with a fixing plate 12 which is bent outwards, and the fixing plate 12 is used for fixing the USB interface on a computer. The inner core 2 is positioned in the center of the fixed frame 1, and the inner core 2 and gaps on two sides of the fixed frame 1 can accommodate the insertion core of the USB plug. The inner core 2 comprises a base 21 and a wedge-shaped structure 22 positioned at the end of the base 21, and the base 21 and the wedge-shaped structure 22 can be integrated or separated. A group of electrodes 23 are respectively arranged on two sides of the substrate 21, and the cross section of the wedge-shaped structure 22 is triangular.

As shown in fig. 1, since the electrodes are disposed on both upper and lower sides of the inner core 2, the insertion core of the USB plug can be inserted into the USB interface both upward and downward. The user can be with the USB plug near one side of USB interface to make the electrode of USB plug towards the center of USB interface, can avoid the collision completely according to this mode, insert the USB plug in the USB interface smoothly.

In addition, because the end of the inner core 2 close to the opening side of the fixed frame 1 is wedge-shaped, and the cross section of the wedge-shaped structure 22 is triangular, that is, the thickness of the front end face of the inner core 2 is very small and is similar to a straight line (as shown by 221 in fig. 1), when the USB plug is inserted, the probability that the inserting core of the USB plug collides with the front end face of the inner core 2 is reduced by half. If the sharp corners at both ends of the wedge structure 22 are cut off, the length of the end 221 is shortened (as shown by 221 in fig. 1), so that the USB plug is inserted more smoothly. In addition, the end 221 may be machined to be an arc surface, so that the front end surface of the inner core 2 and the USB plug may slide when colliding with each other, thereby avoiding hard damage.

As the preferred embodiment of the present invention, the electrodes on both sides of the inner core 2 may be insulated, and at this time, the USB interfaces are equivalent to two independent USB interfaces, and when the card reading device connected by a set of electrodes fails, the use of another USB interface is not affected. Such a USB interface is suitable for various USB plugs on the market.

As the preferred embodiment of the present invention, the electrodes on both sides of the inner core 2 can also be electrically connected, and at this time, a USB interface only needs to be connected with a card reading device, and the two sets of electrodes are mutually backup electrodes. Such a USB interface is suitable for a USB plug having only a ferrule without a protective sleeve.

As a preferred embodiment of the present invention, the inner core is connected to the fixing frame 1 through an elastic member. As shown in fig. 2, the center of the back plate 13 of the fixing frame 1 is provided with a hole through which the tail of the inner core 2 passes, and the elastic member may be a metal sheet 3 shown in fig. 2, the metal sheet 3 is bent, and one end of the metal sheet is fixed on the back plate 13 and the other end is fixed on the inner core 2. As shown in fig. 3, the metal sheets 3 are fixed to both sides of the inner core 2 so that the inner core 2 can swing within a small range. When a USB plug is inserted and the plug end collides with the end 221 of the inner core 2 of the USB interface, the end of the inner core 2 may be shifted to one side to avoid a severe impact, and in the process of shifting the end 221 of the inner core 2, the surfaces of the two sides of the end 221 are inclined to guide the USB plug to be smoothly inserted into the USB interface.

As the preferred embodiment of the present invention, the base 21 and the wedge-shaped structure 22 are detachably connected to each other, as shown in fig. 4, the bottom of the wedge-shaped structure 22 is provided with a protrusion 222, a groove adapted to the protrusion 222 is provided on the end surface of the base 21, and the protrusion 222 is in interference fit with the groove. The wedge-shaped structure 22 is made of relatively soft material, such as plastic or rubber, so as to reduce damage to the inner core and the insertion core of the USB plug when colliding with the USB plug, and can be manually replaced when the wedge-shaped structure 22 is damaged, which is very convenient.

Example 2

Fig. 5 shows a structural schematic diagram of the novel USB plug of this embodiment, the USB plug includes two ferrules 1 and a protective sleeve 2, the two ferrules 1 are respectively fixed on two inner walls of the protective sleeve 2, and a gap between the two ferrules 1 can accommodate an inner core of a USB interface. The back of two lock pins 1 is respectively provided with two positioning grooves, and the protective sleeve 2 is also provided with a hole 21 at the corresponding position to match with the elastic sheet of the USB interface for positioning the USB plug. As shown in fig. 6, a set of electrodes 11 is respectively arranged on the surfaces of the two ferrules 1, and the two sets of electrodes 11 are electrically connected with each other.

The USB plug of the present embodiment is used in cooperation with the USB interface of embodiment 1. Because the two sides of the USB plug are symmetrical, the direction does not need to be distinguished when the USB plug is inserted into the USB interface, the USB plug can be directly inserted, the situation of collision with an inner core of the USB interface cannot occur, and damage can be avoided. In addition, because the USB plug has two sets of electrodes, which are respectively matched with the two sets of electrodes of the USB interface in embodiment 1, no matter a set of electrodes of the USB interface or a set of electrodes of the USB plug fails, data transmission between the storage device and the computer is not affected, stability of data transmission is improved, and service lives of the USB plug and the USB interface are prolonged.

Example 3

Fig. 7 shows a structural schematic diagram of a novel USB plug of this embodiment, where the USB plug includes a ferrule 1 and a protective sleeve 2. The ferrule 1 is fixed to an inner wall of the protective sleeve 2. The protective sleeve 2 is provided with a hole 21 which is matched with the elastic sheet of the USB interface and used for positioning the USB plug. The surface of the ferrule 1 is arranged with electrodes 11, and the end face 12 of the ferrule 1 is an inclined surface.

The USB plug of this embodiment can be used with the USB interface of embodiment 1 or the existing USB interface. Even if the end face 12 contacts with the inner core of the USB interface, the inclined end face 12 can guide the USB plug to smoothly insert into the USB interface, so that the probability of severe collision between the USB plug and the inner core of the USB interface is greatly reduced, and the service lives of the USB plug and the USB interface are prolonged.
