## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention in general relates to an electric connector, in particular, to a USB electric connector for transferring data between two computers.
2. Description of Prior Art
In an early period, when two computers execute a process of data transfer or backup, the electrically connecting ports (printer ports) of the two computers are connected via a transmission line. Therefore, the data of one computer can be transferred to the other one to achieve an object of transferring data between computers.
However, under the development of internet, every computer has a plugged-in or built-in LAN card provided for a user capable of connecting to each website directly through the internet, so the user at a using side can do a shopping at websites or communicate with faraway users. When a user has two computers, which need to transfer data to each other or make a data backup, it is possible to use a RJ45 network cable (crossover) directly connected to the RJ45 electric connectors of the LAN cards of both computers, making the data in one computer transferred to the other one. However, not the all network slots on the LAN card of computer are of RJ45 electric connector. So, in many occasions, it is impossible to make a data transmission between two computers.
Recently, since USB electric connector is comprehensively applied to each kind of electric appliance, in order to solve the aforementioned problems, the industries affix a bridge to the USB transmission line, whereby a bridge chip built in the bridge can manage a data transferring process. Therefore, when two computers are executing a data transfer to each other, the USB transmission line is only plugged in the USB electric connectors of two computers, making the data inter-transferred between two computers become feasible. Although the USB transmission line having bridge can directly connect the USB electric connectors of two computers to undergo a data transmission, the cost of this kind of USB transmission is very high. In other words, the user has to pay extra money to pursue this kind of function.
Therefore, how to improve and solve the aforementioned problems is an issue intended to be addressed by the inventor.
Accordingly, after a substantially devoted study, in cooperation with the application of relatively academic principles, the inventor has finally proposed the present invention that is designed reasonably to possess the capability to improve the drawback of the prior art significantly.
SUMMARY OF THE INVENTION
The invention is mainly to provide a bridge chip built in a USB electric connector, such that a user can use a traditional USB transmission line to connect two computers, making a data transmission between these two computers become feasible.
Secondly, the invention is to provide a USB electric connector for data transmission between computers, including an outer shell, a seat body, a terminal seat, a bridge circuit board and a lid body. The outer shell has a hollow main body, at a front side of which an inserting slot is arranged, and adjoining to an end side and a bottom of which an opening is arranged. The seat body is disposed in the outer shell and has a stop wall at the front side thereof. The stop wall is extended a loading portion. A through hole provided for the terminal set to pass through is arranged on the stop wall. A hollow opening is arranged by adjoining to the rear side and the bottom part of the seat body. Two recesses corresponding to each other are arranged at two lateral walls of the seat body in the opening. The terminal set is comprised of a plurality of electrically conductive legs, one side of each of which is disposed on the loading portion, while another side is extended to an outside of the hollow opening. The bridge circuit board has a bridge chip for managing a data-transferring process. A plurality of inserting holes are arranged at one side of the bridge circuit board and are electrically connected to the electrically conductive legs extended to an outside of the hollow opening. Furthermore, another side of the bridge circuit board is arranged a plurality of electrically conductive pillars, which are electrically connected to a motherboard of an electric device. The lid body is connected by sealing the hollow opening. The electrically conductive pillars pass through the holes on the lid body and are electrically connected to the motherboard of the electric device.

A through hole 23 provided for the terminal set 3 to pass through is arranged on the stop wall 21, making one side of the electrically conductive leg 3 extended on the loading portion 22. In addition, a hollow opening 24 is arranged by adjoining a rear side and a bottom part of the seat body 2. Two corresponding recesses 25 are arranged at two lateral walls of the seat body 2 in the hollow opening 24.
The terminal set 3 is comprised of a plurality of electrically conductive legs 31, each of which has a first section 311 and a second section 312. The first section 311 shown as an arc shape is disposed on the loading portion 22, while the second section 312 shown as an “L” shape is disposed in the through hole 23. One side of the first section 312 is extended to an outside of the hollow opening 24.
A bridge chip 41 arranged on the bridge circuit board 4 is provided for processing a data transmission. A plurality of inserting holes 42 arranged at one side of the bridge circuit board 4 are provided for inserting one side of the second section 312 therein. After being inserted, the second section 312 is electrically connected to the bridge circuit board 4. Another side of the bridge circuit board 4 is arranged a plurality of electrically conductive pillars 43 provided for an electric connection to the motherboard of an electronic device (not shown).

As shown in this figure, the electric connector of the first computer is a USB electric connector 10 according to the present invention, while the USB electric connector 301 of the second computer 30 is a traditional one. When the first computer 20 is transferring data to the second computer 30, the USB electric connectors 10, 301 may be electrically connected via a traditional USB transmission cable 40. More specifically, after the data sent out from the first computer 20 has been processed by the bridge circuit board 4, the data is transferred to the second computer 30 and stored therein. Similarly, after the data sent out from the second computer 30 has been transferred to the USB electric connector 10, the data is processed by the bridge circuit board 4, then, transferred to the first computer 20 and stored therein. Thus, a data transmission between two computers is thereby achieved.
