ABSTRACT:
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the priority benefit of Taiwan application serial no. 88119830, filed Nov. 15, 1999.
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to an adapter, and more particularly to an adapter for connecting an RJ-45 port and an RJ-11 port.
2. Description of Related Art
The hardware of the personal computer has been becoming cheaper and cheaper nowadays, accordingly, the supporting software has been diversified. In addition to the general data processing, the functions of processing on video, audio, and image are gradually enhanced which signify the sign of the advent of a multimedia age. Although the functions of the multimedia personal computer are integrated and independent, in order to share the resources with one another, it becomes necessary to connect them to the computer network to give each of the personal computers a full play on their functions.
The information transmission on the network can go through a lot of various kinds of ports and different types of wire connections to connect to the facilities and devices having different types of functions, and further to attain the object of an effective information transmission. Among them, the different types of ports and wire connections comprise at least a twisted pair RJ-45 port of the category 5 or category 3 for use in the network, and a twisted pair RJ-11 port for connecting to the telephone lines.
Following the rapid development of the various kinds of devices on the network, quite a high percentage of them employ twisted pair RJ-45 devices and twisted pair RJ-11 devices. For instance, the network interface card generally employs RJ-45 twisted pair while the modem employs RJ-11 twisted pair. In the light of these various kinds of wire connections and transmitted data by different type of connectors, a chip set that can share these two different types of data has been provided for mass production.
The only portion of the conventional way of disposition of the connectors is RJ-45 connector to RJ-45 connector, or RJ-11 connector to RJ-11 connector wherein these connectors are either male-to-female, or male-to-male, or female-to-female transferred connections. Therefore, although data can be transferred to one another, predicaments can occur when the connectors can not match one another. However, if the hardware design takes into consideration on the space reserved for accommodating various types of adapters, the size of the hardware will become very large. If one considers not to increase the size of the hardware but to omit some of the original connectors in order to add these connectors for transmitting data for the network and the telephone line etc., then some of the functions of the hardware will have to be diminished. Besides, this kind of design on changing functions of hardware is not an ideal design anyway.
To summarize the above-mentioned statement, the conventional disposition of the connectors has the following disadvantages:
1. The conventional disposition of the connectors can only change the male and female types of connectors but can not transfer between the RJ-45 wire connection into the RJ-11 wire connection.
2. When it comes to employing a lot more different kinds of wire connection, the size of the hardware of the conventional disposition of the connectors will become relatively large which will result in a jam-up of the internal hardware or the circuit of the computer.
3. If one decides not to change the size of the hardware while intending to add new connectors, the conventional disposition of the connectors will have to remove the original connectors that will result in the loss of some of the original functions.
SUMMARY OF THE INVENTION
In the light of the foregoing disadvantages, the present invention provides an adapter for connecting an RJ-45 port and an RJ-11 port that can transfer the connection between RJ-45 and RJ-11. With this kind of adapter, the present invention does not have to increase the size of the hardware on the computer's internal hardware design. On the contrary, the present invention can omit the unnecessary design of connectors and can further increase the space available on the design of the internal hardware of a computer.
An adapter of the present invention for connecting a RJ-45 port and a RJ-11 port consists of at least an RJ-45 port and at least an RJ-11 port. The RJ-45 port is for connecting an RJ-45 device that uses an RJ-45 connector while the RJ-11 port is for connecting an RJ-11 device that uses an RJ-11 connector wherein the RJ-45 port is electrically coupled with the RJ-11 port. Among them, both the RJ-45 port and RJ-11 port can be either a male-connector or a female-connector. The RJ-45 device that uses RJ-45 connector consists of, for example, local area network (LAN) or internet while the RJ-11 device that uses RJ-11 connector consists of, for example, modem and Home Phone Line Networking Alliance (Home PNA).
In an embodiment of the present invention, the adapter can have an RJ-45 port electrically coupled with an RJ-11 port while in another embodiment of the present invention the adapter can have an RJ-45 port electrically coupled with a plurality of RJ-11 ports. Additionally, in one of the embodiment of the present invention, the adapter can have an RJ-11 port electrically coupled with a plurality of RJ-45 ports while in another embodiment of the present invention the adapter can have a plurality of RJ-45 ports electrically coupled with an RJ-11 port.
To summarize the above-mentioned statement, the present invention integrates different types of connectors to create an adapter. The adapter not only can transfer between the RJ-45 connection and the RJ-11 connection, but also can omit unnecessary connector design without increasing the size on the design of the computer's internal hardware, thereby, more space can be saved inside the computer and in those areas for placing connectors.
