Description

The present invention relates to a multi-interface connector port, and more particularly to a structure of a multi-interface connector port that transmits signals to and from a connected multi-interface memory device or a USB format peripheral device via a single common bus.

The market size of small digital models is gradually increasing (for example, digital cameras, video cameras, MP3s, mobile phones, etc.). It was the internal key parts that were directly influenced, but the miniaturization and sophistication corresponding to these, the development using the part technology was also relatively miniaturized, the chip development was the main development direction, and it was close to mini The printed circuit boards of these IC parts are becoming increasingly smaller in volume and higher in density.

The above-mentioned small digital models include memory cards that store video data, digital photographs, MP3 music, game data, etc. (for example, Smart Media (registered trademark) Card, Security
Digital storage devices such as Digital Cards, Multi Media Cards, Memory Stick Cards, CF Cards, XD Cards,...) And memory sticks have already become personal items for many computer users. Compared to floppy disks, memory cards and memory sticks are smaller in volume, but have a larger capacity than floppy disks and faster access speeds. The device is not as damp or broken like floppy disks, and many consumers increasingly use both storage devices as personal items instead of floppy disks. To do.

As shown in FIG. 1, the transmission interface for connecting a memory stick and a memory card on a conventional printed circuit board is different. As a memory stick, the transmission interface is a USB connector. Is a conductive terminal called a gold finger. Therefore, it is necessary to attach an interface corresponding to a USB connector port and a memory card connector on a printed circuit board, which is very inconvenient for application.

In other words, a memory card transmission interface and a USB transmission interface are provided in a connector that conforms to the USB format, thereby forming a multi-interface memory device. The electrical equipment used accordingly is only one connector port corresponding to the common bus, further saves PCB space, simplifies circuit layout and assembly, and further improves overall reliability. And reduce objectives such as inventory and logistics costs. Therefore, the present invention is a problem to be solved.

The present invention has been made in view of such circumstances, and the first terminal group of the USB format and the second terminal group of the multi-transmission interface format are provided on a common bus conforming to the USB connector format. A multi-connector port connected to a circuit of the multi-interface memory device via a common bus is configured. The applied device meets the requirements for signal transmission with multi-interface memory devices or other peripheral devices in USB format.

As shown in FIG. 2, the multi-interface connector port of the present invention has the basic structure of the entire connector port as shown in FIG. Circuit connection). In the meantime, the common bus 30 is provided with the first terminal group 31 in the USB format and the second terminal group 32 in the multi-transmission interface format, and is connected to the circuit of the multi-interface memory device 40 through the single common bus 30. The structure of the multi-connector port is configured.

The arrangement format of the circuit contacts of the first terminal group 31 is a compatible mode that matches the USB connector port, mainly to configure a USB format peripheral device and a device applied to this multi-interface connector port. Data is transmitted through the transmission interface. Some circuit contacts in the second terminal group 32 have a predetermined arrangement mode. Data transmission with a device applied to this multi-interface connector port via a multi-memory card transmission interface so as to constitute a multi-interface memory device mainly connected to a circuit contact in the first terminal group 31 To do.

When concretely implemented, the first terminal group 31 and the second terminal group 32 are provided on the printed circuit board 33 inside the common bus 30 and, as shown in FIG. The groups 32 are provided at two opposed positions, respectively, and the multi-interface memory device 40 format of the circuit contacts 411 is provided on all of the two printed circuit board surfaces of the connector 41.

As described above, the present invention provides an optimal configuration for a multi-interface connector port. However, as shown in the above implementation, description and drawings, the present invention is not limited to the scope of implementation of the present invention, and is not limited to the scope of implementation of the present invention. It belongs to the claims of the invention.

The multi-interface connector port of the present invention is such that the applied device satisfies the requirements for signal transmission with the multi-interface memory device or other peripheral devices in the USB format. Furthermore, it aims at saving the space of a printed circuit board, simplifying circuit layout and assembly, further improving the overall reliability, and reducing the cost of inventory and logistics.

It is a reference figure of the use state of the conventional memory stick and memory card of the present invention. It is a reference figure of the use condition of the multi-interface connector port of this invention. FIG. 3 is a cross-sectional view of the connection of the multi-interface connector port of the present invention and the connector of the multi-interface memory device.
