Description
Field of the Invention
This invention relates generally to mounting devices within the case of a computer, and more particularly to connection of the devices to external communication lines.
Background
Often it is desirable to mount a device within the case of a computer. When the space within the case is severely limited, as it is in a laptop type computer, details of mounting the device become critical. The details of mounting the device are especially critical when the device has ports for connection to external electrical circuits such as communication lines.
Many standard devices for connecting a computer to communications lines are available on the marketplace. Also, new versions of the standard devices are produced with short development times. Accordingly, it is desirable to be able to update the device mounted within a computer to a different type of device, for example a modem to an Ethernet connection, and also to be able to change the device as new and better models are placed on the marketplace by device vendors.
For example, a PCMCIA card is a type of device for which a convenient mounting within a computer is desirable. PCMCIA is an acronym which stands for Personal Computer Memory Card International Association. PCMCIA architecture is disclosed further in the book "PCMCIA System Architecture" second edition, author Don Anderson, published by MindShare, Inc., and Addison Wesley, in 1995, all disclosures of which are incorporated herein by reference.
Also, it is desirable that the computer be easy for a user to connect to the external communications lines. Various methods of connection to external communications lines have been proposed.
However, there remains an unsolved need to easily connect a standard type of communication device to external communication lines in a manner that makes the computer easy to use, while also making it easy for the device to be changed when the user desires to change the nature of the device, or to update the device to a newer model.
Summary of the Invention
A computer having a case has a connection point for a communications line, where the connection point is accessible from outside the case. A socket receives a standard communications hardware card, the hardware card having a first receptacle to electrically connect to circuits of the computer, and the hardware card having a second receptacle to electrically connect to an exterior electrical circuit, the exterior electrical circuit usually being exterior to the case. A mounting means attaches the socket to the computer, the mounting means positioning the socket to permit a connection to the second receptacle of the hardware card, the connection located wholly internal to the case. A multi wire connector electrically connects to the second receptacle of the hardware card, and the multi wire connector is located wholly internal to the case. At least one signal wire has a first end electrically connected to the multi wire connector, and the at least one signal wire has a second end electrically connected to the connection point, the at least one signal wire is located wholly internal to the case, and the at least one signal wire transfers communication signals between the connection point and the hardware card in order to connect the computer to the communications line.
The multi wire connector which electrically connects to the second receptacle of the hardware card and is located wholly internally to the case may be located adjacent to an opening in the case, and the opening facilitates inserting the card into the socket. A cover is provided for the opening, the cover closes the case during normal operation of the computer, the cover is removed from the opening for the purpose of removing or inserting the card in the socket.
The communications line may be a telephone circuit. The communications line may be a link to a local area network. The communications line may be an Ethernet local area network connection. The hardware card may be a PCMCIA standard card. The computer may be a laptop type computer. The signal wire and the multi wire connector may be made as a single unit, for example they may be a single molded part.
Other and further aspects of the present invention will become apparent during the course of the following description and by reference to the accompanying drawings.
