1. Field of the Invention
The present invention relates to a mini-USB connector assembly, and in particular to a mini connector assembly with a universal series bus interface that is suitable for portable electronic appliance and is plug-and-play.
2. Description of Related Art
Universal Serial Bus (USB) interfaces are introduced to computer-related appliances. The USB interface is configured to support plug-and-play device and is hot-swappable. That is, the USB interface has a capability to be plugged or unplugged without removing the power or rebooting the computer. One USB connector is allowed for up to 127 peripherals to be attached including speakers, telephone sets, CD-ROM drives, joysticks, magnetic tap devices, keyboards, scanners and digital cameras. The USB connection ports are usually positioned near parallel ports or serial ports.
Especially, mini-USB ports are implemented in portable electronic appliances so that the portable electronic appliances are plug-and-play. To be compatible with current specification, the mini-USB ports are only configured with four terminals so that the mini-USB ports do not deal with demand for more data and higher transfer speed.
Thus, there is a need for a new mini-USB connector assembly.
It is an object of the present invention to provide a mini-USB connector assembly with more terminals to fasten the transfer speed without enlarging its volume.
To achieve object of the present invention, a mini-USB connector assembly includes a male USB connector and a female USB connector. The male USB connector includes an isolation body, a front metallic housing, a rear metallic housing and a plurality of terminals. The isolation body includes a main body and a extension plate extending from the main body. The extension plate is enclosed by the front metallic, and a top surface of the extension plate abuts against a top plate of the front metallic housing. An insertion space is formed between the extension plate and the front metallic housing. Periphery of the main body is enclosed by the rear metallic housing. The terminals are manufactured by an insert molding process, and the terminals are positioned alongside on the bottom surface of the extension plates and penetrate through the main body so that the terminals can be soldered to a circuit board. The female USB connector includes a corresponding isolation body, a corresponding metallic housing and a plurality of corresponding terminals. The corresponding isolation body includes a corresponding main body and a corresponding extension plate extending from the corresponding main body. The corresponding extension plate is positioned within the insertion space. The corresponding isolation body is enclosed by the corresponding metallic housing. In addition, the corresponding terminals are manufactured by an insert molding process, and the corresponding terminals are positioned alongside on the top surface and the bottom surface of the corresponding extension plates and penetrate through the corresponding main body so that the terminals can be soldered to a circuit board.
The present invention can be fully understood from the following detailed description and preferred embodiment with reference to the accompanying drawings, in which:
The following detailed description is of the best presently contemplated modes of carrying out the invention. This description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating general principles of embodiments of the invention. The scope of the invention is best defined by the appended claims.
Reference is made to
To begin with, reference is made to
The isolation body 12 is made of isolation material and includes a main body 121 and a extension plate 122a and 122b extending from the main body 121. The terminals 18a and 18b are respectively positioned alongside at a bottom surface and a top surface of the extension plate 122 and penetrate through the main body 121 so that the terminals can be soldered to a circuit board (not shown).
Because the present invention includes 12 terminals, it is rather difficult to put the terminals into the male USB connector in an assembling way. According to the present invention, the terminals 18a and 18b are fixed within the isolation body 12 by an insert molding process without assembling by manpower. That is, the terminals are positioned within a mold of the isolation body 12 beforehand, and melt material is poured into the mold of the isolation body 12. In this regard, when the isolation body 12 is formed, the terminals 18a and 18b are already fixed therein.
The present invention has a prerequisite condition that the volume of the mini-USB connector assembly will not be enlarged. As shown in

The corresponding metallic housing 24 is formed by bending metallic plate and is used to enclose periphery of the corresponding isolation body 22.
The terminals 26a and 26b are respectively positioned at the corresponding extension plate 222 and penetrates through the corresponding main body 221 so that the terminals 26 can be soldered to the circuit board (not shown). According to the present invention, the terminals 26a and 26b are manufactured by the insert molding process and positioned within the corresponding isolation body 22.

Reference is made to
A pair of protrusions 223 are integrally formed with and extend from the corresponding main body 221 of the female USB connector 20 to aid the female USB connector 20 to be fixed at the circuit board.
As described above, advantages of the present invention are in the following.
1. According to the present invention, the male USB connector and the female USB connector of the mini-USB connector assembly respectively have 12 terminals so that transfer speed can be improved.
2. The terminals of the present invention are manufactured by the insert molding process so that the terminals are positioned within the isolation body and the corresponding isolation body without assembling by manpower.
3. According to the present invention, the main body 121 is firmly positioned within the rear metallic housing 16. The main body 121 is not only moved back and forth within the rear metallic housing 16 but the main body 121 is also moved along the vertical direction within the rear metallic housing 16 by the fixing plate 164.
While the invention has been described with reference to the preferred embodiments, the description is not intended to be construed in a limiting sense. It is therefore contemplated that the appended claims will cover any such modifications or embodiments as may fall within the scope of the invention defined by the following claims and their equivalents.
