Description

External relay box device for computer peripheries

The present invention facilitates the connection or disconnection of the computer and peripheral devices by connecting external relay box devices for computer peripheral devices, in particular, connectors located at the back of the main unit of the computer, to the signal cable assembly through corresponding signal connectors provided in the relay box. It relates to a relay box device that can be made.

In general, a personal computer provides an interface for connecting peripheral devices to the back of the computer in consideration of the good appearance of the entire front panel and the structure of the motherboard. Primarily, peripherals that are initially connected to the computer main unit are keyboards, printers, or cursors so that there is no problem in positioning the back panel while the printer's connector or PS2 connector is in use in the computer. In the multimedia age, various peripheral devices such as scanners, CD-RWs, digital cameras, DV cameras, MP3 players, PDAs, modems, and loudspeakers are continuously developed. Some of the peripherals mentioned are portable, but connectors such as the RS-232 port, Universal Serial Bus (USB) port, or IEEE port (Firewire port) are still mounted by the computer manufacturer on the back panel of the main unit to provide the user with It is worth noting that it presents the difficulty of carrying the computer as soon as it is connected to or disconnected from the computer.

Therefore, the manufacture of an easy carrying board for improving the disadvantages of the mentioned interface device has been developed. Easy carrying boards connect multiple signals such as two USB ports on the front panel, an IEEE1394 port, a voice line-in port, a voice line-out port, and an RS-232 serial port. It is a 3.5-inch semi-sealed box with a circuit board to connect with the connector. It is necessary to remove the casing of the computer mainboard before the easy transport board is directly fixed to the space for the 3.5 'disk drive or the space for the 5.25' disk drive by the displacement frame. At this time, one end of the signal cable on each signal connector provides a plug for engaging the relay connector on the circuit board and the other end of the signal cable for engaging each connector on the back plate of the main unit through the main unit and slot on the back plate. Provide a signal connector. (Note that the signal cable of the RS-232 serial port must be installed in reverse.) Finally, the casing is secured back to the main unit to complete the task of mounting the easy carrying board.

Although the peripherals of the portable computer can extend the signal of each connector of the main unit to the front panel so that it can be conveniently connected directly to the main unit, this increases the difficulty and difficulty for the user while the carrying board is mounted on the main unit. You can also give In addition, any signal cable that cannot be extended and collected independently can affect the normal operation of the computer and can lead to drawbacks such as undesirable signals, interference, and poor heat dissipation. In addition, this often affects the operation of the loading tray when sliding in / out of the CD-ROM drive while the signal wires of each peripheral are coupled with the signal connector of the carrying board. In particular, the overall aesthetics of the front panel on the main unit are detrimental.

It is an object of the present invention to provide an external relay box device for a computer peripheral device, which is a relay box and signal cable assembly for configuring an easily operated connection between a computer's good main unit and a peripheral device for a user. It includes.

Connected. Thus, each signal between the signal connector 12 and the box connector 14 is independent and separated from each other so that no crosstalk can occur between all signals.

The signal cable assembly 2 is a device having a set of long wires and at one end of the signal cable assembly 2 is provided a cable connector 21 for insertion into the relay box 1 for coupling with the box connector 14. At the other end, the signal wires are wrapped as bundles having at least the strands of the signal wire bundles. Each bundle of signal wires includes two USB plugs 221, an RS-232 plug 222, a set of acoustic line in / line out plugs 223, a microphone plug 224, or a firewire plug 225, and the like. A plurality of extension plugs 22 is provided. Alternatively, it is within the scope of the present invention that the box connector 14 can be located in the relay box 1 and the cable connector 21 can be coupled to the box connector from the outside.

And a corresponding connector on a computer such as a microphone port, and an IEEE 1394 port. The cable connector 21 at the other end of the signal cable assembly 2 is inserted into the box connector 14 for connection. That is, each connector 21 on the main unit extends to the corresponding signal connector 12. In that regard, the relay box 1 is an independent box that can be installed on a flat work surface, such as a table top of a computer support.
