1. Field of the Invention
The preferred embodiment relates to a universal serial bus (USB) connector and, more particularly, to a USB connector with detachable USB plugs.
2. Description of the Prior Art
Nowadays, USB is the most popular peripheral bus in computer industry and consumer electronic products. USB can be used to connect various peripheral devices, such as keyboard, mouse, flash driver, card reader, digital camera, personal digital assistant (PDA), smart phone, and so on. Due to plug and play capability and usage convenience, USB is available to most of applications in the market. So far there are lots of USB applications developed by peripheral and computer manufactures and there are also lots of drivers and programs developed correspondingly.
At present, a data transmission rate of USB 2.0 is 480 Mbps, and a data transmission rate of USB 3.0 is 5 Gbps, which is five times that of USB 2.0. Compared with USB 2.0, USB 3.0 may save much power. Furthermore, USB 3.0 is compatible with USB 2.0. Referring to table 1 in the following, table 1 shows various relations between USB 2.0/3.0 plugs and receptacles.
As shown in table 1, in type 3, USB 2.0 standard-B receptacle only can be connected to USB 2.0 standard-B plug; in type 6, USB 2.0 micro-B receptacle only can be connected to USB 2.0 micro-B plug; and in type 8, USB 2.0 micro-AB receptacle only can be connected to USB 2.0 micro-B or micro-A plug.

As mentioned in the above, since the conventional USB 3.0 connector has undetachable plug structure, it cannot be connected to an electronic device equipped with a USB 2.0 standard-B, micro-AB or micro-B receptacle only. It is very inconvenient for users.
Therefore, an objective of the preferred embodiment is to provide a USB connector with detachable USB plugs, so as to solve the aforesaid problems.
A USB connector of the preferred embodiment is adapted to a USB receptacle in compliance with a first USB standard and another USB receptacle in compliance with a second USB standard. The USB connector comprises a first USB plug and a second USB plug. The first USB plug is also in compliance with the first USB standard. The second USB plug integrated with the first USB plug is in compliance with a second USB standard different from the first USB standard. In this embodiment, the second USB plug is detachably connected to the first USB plug.
In practical applications, the first USB standard may be USB 2.0 standard, and the second USB standard may be USB 3.0 standard. For example, if the USB receptacle is a USB 2.0 standard-B receptacle, the first USB plug is a USB 2.0 standard-B plug, and the second USB plug integrated with the first USB plug is a USB 3.0 standard-B plug; if the USB receptacle is a USB 2.0 micro-B receptacle, the first USB plug is a USB 2.0 micro-B plug, and the second USB plug integrated with the first USB plug is a USB 3.0 micro-B plug; if the USB receptacle is a USB 2.0 micro-AB receptacle, the first USB plug is a USB 2.0 micro-B or micro-A plug, and the second USB plug integrated with the first USB plug is a USB 3.0 micro-B or micro-A plug.
Once an electronic device only has a USB 2.0 standard-B, micro-AB or micro-B receptacle, a user can detach the first USB plug from the second USB plug and then inserts the first USB plug (e.g. USB 2.0 standard-B, micro-A or micro-B plug) into the USB 2.0 receptacle correspondingly for purpose of data transmission or charge. Accordingly, it is very convenient for users.
These and other objectives of the present invention will no doubt become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiment that is illustrated in the various figures and drawings.

In this embodiment, the first USB standard may be USB 2.0 standard and the second USB standard may be USB 3.0 standard. In practical applications, the first USB plug 40 may be a USB 2.0 standard-B plug, and the second USB plug 42 integrated with the first USB plug 40 may be a USB 3.0 standard-B plug.
As shown in
The two independent USB plugs can be connected to each other through various manners, so as to increase usage convenience. In this embodiment, the first USB plug 40 has a first engaging portion 400 and the second USB plug 42 has a second engaging portion 420. The first engaging portion 400 can be engaged with or disengaged from the second engaging portion 420. For example, when an electronic device has a USB 3.0 standard-B receptacle, a user can engage the second engaging portion 420 with the first engaging portion 400 to connect the first USB plug 40 and the second USB plug 42 and then inserts the USB connector 4 into the USB 3.0 standard-B receptacle correspondingly for purpose of data transmission or charge. On the other hand, when an electronic device only has a USB 2.0 standard-B receptacle, a user can disengage the second engaging portion 420 from the first engaging portion 400 to separate the first USB plug 40 and the second USB plug 42 and then inserts the first USB plug 40 (i.e. USB 2.0 standard-B plug) into the USB 2.0 standard-B receptacle correspondingly for purpose of data transmission or charge.

In this embodiment, the first USB plug 60 has a first engaging portion 600 and the second USB plug 62 has a second engaging portion 620. The first engaging portion 600 can be engaged with or disengaged from the second engaging portion 620. The operation manner and structure design of the first and second engaging portions 600, 620 are similar to the aforesaid first and second engaging portions 400, 420, and the related description does not be depicted here again.
Moreover, the first USB plug 60 may also be a USB 2.0 micro-A plug adapted to a USB 2.0 micro-AB receptacle (not shown). The main difference between the USB 2.0 micro-A and micro-B plugs is the shape of opening, and the related description does not be depicted here again.

According to the USB connector of the preferred embodiment, once an electronic device only has a USB 2.0 standard-B, micro-AB or micro-B receptacle, a user can detach the first USB plug from the second USB plug and then inserts the first USB plug (e.g. USB 2.0 standard-B, micro-A or micro-B plug) into the USB 2.0 receptacle correspondingly for purpose of data transmission or charge. Accordingly, it is very convenient for users.
Those skilled in the art will readily observe that numerous modifications and alterations of the device and method may be made while retaining the teachings of the invention.
