ABSTRACT:

FIELD OF THE INVENTION
This invention relates to an improvement for terminal connection box and plug that uses an enhanced signal circuit to connect a 1394 type-plug for transmitting data signal at fast speed.
BACKGROUND OF THE INVENTION
This invention is to improve the conventional terminal connection box that was developed by the same applicant and was filed as Taiwan patent application Ser. No. 86210961. The conventional terminal connection box has selected configuration in a box to connect plug, terminal socket and external cable to facilitate connection and disconnection of terminal and plugs between a computer and peripheral devices.
FIG. 1
shows a convention terminal connection box
10
which includes a holding means
20
and a terminal socket
31
located in a rectangular box. On each side wall, there is a gate opening
101
wedge with a sliding means
12
which may be inserted into or pulled out from the gate opening
101
. The sliding means
12
may include a baffle
11
. One of the baffles has an opening
111
to receive an external cable
51
into the box
10
.
The holding means
20
includes a holding member
21
and a plurality of trough holding slots
22
each may engage with a plug
40
. The holding slots
22
further have a terminal socket
31
for latching the plug
40
. And there is a third holding slot
223
for fastening the plug
40
as depicted in the Taiwan patent application Ser. No. 86210961.
FIG. 2
shows another conventional terminal connection box
10
which is largely constructed like the one shown in FIG.
1
. However in the holding means
20
, there are a plurality of leads
52
which may establish connection with the external cable
51
through a connection means
32
. The connection means
32
includes a plurality of the notch slots. Each notch slot has a screw
323
to fasten a metallic upper plate
321
against a lower plate
322
in the slot. One lead
52
and one terminal from the external cable
51
are clamped between the upper plate
321
and lower plate
322
for establishing electric connection.
While the conventional connection boxed set forth above may enable a plurality of peripheral device to connect or disconnect with the computer easily, signal transmission intensity will diminish when the peripheral devices are located at a long distance from the computer. There is still room for improvement.
SUMMARY OF THE INVENTION
It is an object of this invention to provide an improvement for terminal connection box and plug that has an enhanced signal circuit to boost signal intensity so that data and signal transmission between the peripherals, particularly those use USB and 1394 type connectors, may remain sufficiently strong even at a long distance from the computer to ensure smooth operation.
In one aspect, the enhanced signal circuit uses a data conversion processor to process data conversion. As input data and data under transmission may be different, the conversion is needed for proper data transmission.
In another aspect, the enhanced signal circuit includes a process circuit, a lock phase circuit, a data receiving unit and an output/input port connecting with the data conversion processor. Input signals are processed. Output signals are generated and delivered to selected terminals to complete signal transmission.
In yet another aspect, the terminal connection box includes a plurality of terminal plugs for connecting with a plurality of peripherals with the computer through the enhanced signal circuit.
