## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to connectors, in particularly to connectors for transmitting optical signals.
2. Description of Related Art
As the electronic industry growing rapidly, nowadays various kinds of electronic devices are used in our daily lives. For inputting commands to control the electronic devices, or transmitting information from one electronic device to another, at least one connector is arranged on a circuit board of the electronic device.
For example, a personal computer usually has a plurality of connectors such as universal serial bus (USB) connectors, external serial advance technology attachment (e-SATA) connectors, RJ-45 connectors, high definition multimedia interface (HDMI) connectors. With the connectors, the personal computer is capable of communicating with external controlling devices and receiving controlling commands, or the personal computer can be connected to another electronic device for mutually transmitting information.
Since the available area on the circuit board is limited and not enough for arranging all kinds of connectors thereon, a stacked connector assembly having multiple connectors arranged vertically with respect to the circuit board is provided. The stacked connector assembly occupies the same area as one conventional connector does and no additional space is further required, thus the number and the types of the connectors to be arranged on the circuit board can be increased.
However, when the manufacturing of the stacked connector assembly is completed, the selected connectors integrated therein can not be changed. When a different type connector that can not be coupled to any one port of the stacked connector assembly is occasionally used, there is still a need to further arrange an additionally corresponding connector on the circuit board.
Therefore, if there is a connector assembly for welding onto the circuit board that can be made for coupling with every kind of connectors and needs not to be detached from the circuit board while adapting a different connector, it will be more convenient for user to use.
SUMMARY OF THE INVENTION
The main objective of the present invention is to provide a universal modular connector, capable of transforming every kind of electric signals into optical signals and transmitting it out and every kind of transmitting interfaces can be integrated into the universal modular connector.
For achieving the above objective, the universal modular connector of the present invention includes a base and a transforming module. The base has a first opening thereon, and the base further has an optical component therein. The transforming module has a circuit board, a plurality of connection terminals, a first signal transforming integrated circuit (IC), and at least one fiber optic connector therein. The transforming module receives external electronic signal through the connection terminals, and transforms the received electronic signal into optical signal via the first signal transforming IC. The transforming module is connected with the base through the first opening, and the optical component of the base receives the transformed optical signal sent by the fiber optic connector of the transforming module. Therefore, the universal modular connector transmits the optical signal externally to an electronic device via the optical component.
The present invention provides the universal modular connector for transforming every kind of electronic signals into a same optical signal by replacing the transforming module of different types of transmission interface. User needs only to replace the corresponding transforming module to transmitting information data, thus needs not to detach any connector from the circuit board while adapting a different connector, it will improve convenience for user.
