Abstract
An extendable/retractable media connector for extending from an electronic device such as a PCMCIA type-III card or other electronic device. The connector includes a slidable extendable/retractable frame having an aperture therein for physically receiving a media plug. The aperture further includes electrical contacts for operably mating with complementary contacts on the media plug. The connector further includes a rotatable electrical interface between the fime, a portion of which may be physically attached to the frame in the form of electrical tracks, which provides commutator-like electrical coupling between the electrical contacts in the aperture and electronic circuitry within the electronic device or card. The connector provides rotational freedom to the media connector and any accompanying cabling while coupled with the connector and further facilitates various angles of insertion of the media plug into the connector for user convenience and ease of attachment.
Description




BACKGROUND OF THE INVENTION




1. The Field of the Invention




The present invention relates to electrical interface connections. More particularly, it relates to extendable media connectors that are configured to couple with physical/electrical media plugs.




2. The Relevant Technology




The ability to freely access data on a network and to transfer information between electrical apparatus can dramatically increase productivity and reduce overall production time. Accordingly, electrical apparatus have been equipped with means to access electronically retrievable data over networks, such as the Internet, a world wide network, local area networks (“LANs”) and wide area networks (“WANs”). The transfer of data over a network can be accomplished with wireless technology or by telephone lines and cables. The interface between a computer and a cable or telephone line is typically accomplished through a media connector.




One conventional type of media connector is the Registered Jack connector (RJ-series connector). RJ-series connectors are used by almost all telephone companies throughout the world for many applications, the most important of which is interconnection of telephones with telephone lines. For this reason, stringent standardization of connectors has been established to enable compatibility and interactivity. Due to the simplicity of the connection and the established standards, RJ-series connectors are used extensively in the computer industries and in other industries where communication over telephone lines or other types of cables is required.




RJ-series connectors include a plug or contact block and a receptacle or socket. The plug comprises a small block shaped body coupled with a cable, such as a telephone line. Housed within the body are several contact pins. Each of the contact pins is attached to a discrete wire within the cable. Mounted on the outside of the body is a flexible retention clip that is used for removably securing the body of the plug within the socket of an electrical apparatus.




The socket is typically formed on the side of the electrical apparatus and is configured to receive the plug. Disposed within the socket are electrical contact wires. During use, the contact wires within the socket are biased against corresponding contacts on the plug to complete an electrical connection between the plug and the electrical apparatus.




The interior surface of the socket comprises a latching mechanism that receives the retention clip of the plug so as to mechanically secure the plug within the socket by holding retention notches of the retention clip securely in place. To remove the plug, the retention clip is manually flexed towards the body of the plug to release the hold of the latching mechanism on the retention notches, thereby enabling manual removal of the plug from the socket.




As the computer industry continues to develop, new peripheral devices are created that enable users to freely access data on networks and to transfer information between electrical apparatus. There are many types of peripheral devices, including, but not limited to wireless cellular modems, facsimile modems, modular random access memory, and network interface connectors. However, because of size constraints, most computers, particularly portable computers, are designed to incorporate only some of the available peripheral devices. Incorporating every available device into a single computer would substantially increase the price of the computer while decreasing its portability. Furthermore, a computer user may not require or desire all of the available peripheral devices. Accordingly, the computer industry has developed standards that enable a computer user to selectively integrate and interchange various peripheral devices.




These standards have been promulgated by the Personal Computer Memory Card International Association (PCMCIA). PCMCIA standards specify spatial size restrictions and coupling interface restrictions. According to PCMCIA standards, there are three types of card architectures. A type-I PCMCIA card has a thickness of approximately 3.3 mm. A type-II PCMCIA card has a thickness of approximately 5 mm. A type-III PCMCIA card has a thickness of approximately 10.5 mm. Each of these card types also have a 68-pin female connector, a width of 55 mm, a length of 85 mm, and edges that are configured to slidably engage channels of a corresponding expansion slot in an electronic apparatus.




PCMCIA standards enable a computer user to selectively use a first peripheral device and later remove it when it is no longer needed. This is particularly useful because it enables a computer user to interchange peripheral devices based on particular needs. When a PCMCIA card is used to access a network or to transfer information between electrical apparatus, the PCMCIA card must be provided with an interface to a media link or media plug. One way to interface a PCMCIA card with an appropriate media plug is to use an adapter. One skilled in the art will recognize a dongle as a typical adapter. Although dongles and other adapters provide one means for interconnecting media plugs with PCMCIA cards, they are also problematic. In particular, they have to be stored and they can easily be misplaced.




One alternative to adapters is to design a socket into the PCMCIA card so that it can directly interface with an appropriate media plug. This is a viable solution for the thicker type-III PCMCIA cards. One problem encountered by this solution, however, occurs during nonuse, when the socket is not occupied by a media plug and is left open to the environment. This is a problem because the socket becomes a sink for dust and debris, which is harmful if it accumulates and prevent the contact pins of the media plug from successfully interfacing with the PCMCIA card. Debris and exposure to the environment can also cause ancillary damage to electrical contact wires within the PCMCIA card. For example, an object inadvertently inserted into the socket may electrically short out or physically deform the electrical contact wires of the PCMCIA card. One solution to these problems is to cap the socket with a plug during nonuse to protect it from harmful dust and debris. However, this solution has its own problems. As with adapters, plugs require additional handling, they must be stored and they can easily be misplaced. Accordingly, it would, therefore, be desirable to provide a media connector that can protect the socket and electrical contact wires from harmful dust and debris during nonuse without having to store additional components such as plugs.




Another problem encountered by traditional sockets is that they cannot accommodate both RJ-11 series plugs and RJ45 series plugs. Typically, RJ-11 series plugs are used as an interface to connect to the internet or for standard modem applications using normal telephone lines. RJ45 series plugs are typically used as an interface to connect to LANs. The body of an RJ-45 series plug is wider than the body of an RJ-11 series plug because it houses eight contact wires, whereas, the RJ-11 series plug houses only four or six contact wires. Accordingly, a socket that is configured to accommodate an RJ-11 series plug is too narrow to receive the body of an RJ-45 series plug. And a socket that is configured to couple an RJ-45 series plug is too wide to securely couple with an RJ-11 series plug because the space between the socket walls and the body of the RJ-11 series plug allows the plug to wiggle back and forth. Accordingly, it would be desirable to provide a media connector that can securely accommodate both RJ-11 and RJ-45 series media plugs so that only a single media connector is required for a PCMCIA card to access both the internet and LAN's.




Another problem encountered by traditional sockets is that they are configured to couple with a media plug from only a single direction. For example, when a media plug is attached to a very short cord its mobility is limited, restricting the directions from which it can be inserted into a socket. Yet another problem encountered by incorporating traditional sockets into an electrical apparatus or peripheral computer card device is that visibility to the socket is restricted because the socket is recessed beyond the profile of the electrical apparatus. Although a computer user may lean over to view the socket while manipulating the media plug into the socket, it is often necessary to move the electrical apparatus to provide a better angle of vision before the media plug can be successfully navigated into the socket. Accordingly, it would, therefore, be desirable to provide a media connector that can easily be coupled with media plugs from different angles of orientation without requiring the electrical apparatus to be moved and without requiring the computer user to exert undue effort.




BRIEF SUMMARY OF THE INVENTION




To achieve the foregoing objects, and in accordance with the invention as embodied and broadly described herein, an extendable media connector is provided for coupling with RJ-series media plugs.




The RJ-series media plug comprises a small block shaped body coupled with a cable, such as a telephone line. A flexible retention clip is mounted to the body of the plug and protrudes away from the body at a slight angle, terminating at a narrow free end. The retention clip has retention notches that define the edges where the retention clip significantly narrows. Housed within the plug body are distinct contact pins. Each of the contact pins is attached to a discrete wire within the cable.




The extendable media connector of the present invention comprises a frame, a rotatable electrical interface and electrical contacts. The frame is rotatably mounted to a type-III PCMCIA card housing and is slidably retractable into the housing of the PCMCIA card. The frame has an aperture that extends into the side of the frame and is configured to couple with a corresponding physical/electrical media plug. When the frame is retracted into the housing of the PCMCIA card, the aperture is sheltered and protected from dust and debris.




The aperture is configured to couple with both RJ-11 and RJ-45 media plugs. When such a media plug is inserted into the aperture, the electrical contacts of the extendable media connector bias against the contact pins of the media plug, effectuating an electrical connection between the media plug and the PCMCIA card through a rotatable electrical interface. The rotatable electrical interface enables the frame to rotate while maintaining an electrical connection between the media plug and the PCMCIA card. The rotatable electrical interface is useful because it enables a media plug to be coupled with a PCMCIA card from various angles of orientation.




The frame mechanically secures the media plug within the aperture by latching onto the retention notches of the retention clip. After use, the media plug can be removed from the aperture by manually flexing the retention clip towards the body of the plug. This releases the hold of the frame on the retention notches of the retention clip and allows the media plug to be freely removed.




It should be appreciated that the extendable media connector of the present invention may be modified without departing from the spirit of the present invention. For example, the frame of the extendable media connector may comprise various shapes and configurations. In particular, the rotatable electrical interface may also comprise various configurations of armatures and commutators.




In one embodiment, the frame is rotatably connected to a type-III PCMCIA card and comprises a rectilinear block that is slidably retractable into the housing of the PCMCIA card. In this embodiment, the rotatable electrical interface may include a substantially flat surface having a plurality of electrical tracks that make contact with electrical brushes of the PCMCIA card. In an alternative configuration, the rotatable electrical interface may include an armature that makes electrical contact with brushes of the PCMCIA card. The rotatable electrical interface may also include brushes that are attached to the frame and make contact with electrical tracks of the PCMCIA card.




In another embodiment, the frame is rotatably connected to a type-III PCMCIA card and comprises a cylindrical block that is slidably retractable into the PCMCIA card housing. In this embodiment, the rotatable electrical interface may include a substantially flat surface having a plurality of electrical tracks or an armature that makes contact with electrical brushes of the PCMCIA card. Alternatively, the rotatable electrical interface may include brushes that are attached to the frame and make contact with electrical tracks of the PCMCIA card.




In yet another embodiment, the frame comprises a cylindrical block that is rotatably mounted to a rectilinear block that is slidably retractable within a type-III PCMCIA card housing. In this embodiment, the rotatable electrical interface is attached to the cylindrical block and includes a plurality of electrical tracks that are disposed on a substantially flat surface at the end of the cylindrical block. The electrical tracks make contact with corresponding electrical brushes housed within the rectilinear block. In an alternative configuration of this embodiment, the rotatable electrical interface may include brushes that are attached to the frame and make contact with electrical tracks of a PCMCIA card that are mounted on the slidably retractable rectilinear block. It is also possible for the electrical tracks to be disposed around a shaft running through the center of the cylindrical block that make contact with electrical brushes located on the cylindrical block.




In yet another embodiment, the slidably retractable frame may retract directly into the body of the host system or device wherein an intermediary PCMCIA card is not employed. In such an embodiment, the extendable media connector directly mounts to the circuitry within the host or device system.




One of the benefits of the present invention is that it provides an extendable media connector that can couple with both RJ-11 series plugs and RJ45 series plugs from various angles of orientation. The present invention also provides a flexible and mobile connection between the extendable media connector of the present invention and a suitable physical/electrical media plug while protecting the aperture and electrical contacts of the extendable media connector from ancillary damage and the accumulation of harmful dust and debris. These and other objects and features of the present invention will become more fully apparent from the following description and appended claims, or may be learned by the practice of the invention as set forth hereinafter.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS




The present invention relates to extendable media connectors for coupling with physical/electrical media plugs.




The extendable media connector of the present invention is configured to electrically and mechanically couple with a corresponding physical/electrical media plug, hereinafter “media plug.” Examples of media plugs include, but are not limited to, RJ-11 and RJ45 series plugs. In many of the depicted examples, the inventive modular jack is configured to receive RJ-series plugs. However, it should be appreciated that the present invention contemplates that it would be obvious to one skilled in the art based on the present disclosure to modify the depicted modular jack to receive other types of media plugs including nonstandard plugs and media plugs that are developed or standardized in the future.




The term “electrical apparatus,” as used in the specification and appended claims, is broadly intended to include any apparatus having electrical components. By way of example and not limitation, some of the more conventional electrical apparatus include: network computers, laptop computers, personal computers, notebook computers, PDA's, and modems. Non-conventional electrical apparatus can include, among other things, televisions, stereo equipment, other electrical musical devices, electrical tools, electrical appliances, and automobiles.




The extendable media connector of the present invention is depicted in the preferred embodiments as being connected to a conventional type-III PCMCIA card. However, it should be appreciated that the extendable media connector of the present invention can be modified and attached directly to various peripheral computer devices or electrical apparatus without departing from the spirit of the present invention.




As depicted in

FIG. 1

, the extendable media connector


10


of the present invention is connected to a communications card device


12


that can be inserted into an expansion slot of an electrical apparatus


14


. In one presently preferred embodiment, the communications card device


12


has a type-III PCMCIA card housing


16


. However, it should be appreciated that the extendable media connector


10


of the present invention can be modified to connect to a variety of peripheral communications card devices


12


and may even be modified to connect directly to an electrical apparatus


14


.




The extendable media connector


10


has an aperture


18


that is configured to couple with a media plug


20


. In

FIG. 1

, the aperture


18


is shown to be open and exposed to the environment and is located at the end of the extendable media connector


10


. In other embodiments, as will be described herein, the aperture


18


is hidden within the housing


16


of the communications card device


12


, during nonuse, when it is not coupled with a media plug


20


.





FIG. 2

illustrates a typical embodiment of a media plug


20


that is suitable for coupling with the extendable media connector


10


of the present invention. As shown, the media plug


20


comprises a small block shaped body


22


coupled with a cable


24


, such as a telephone line. The plug body


22


has a plug nose


26


extending away from the body


22


in the opposite direction of the cable


24


. A flexible retention clip


28


is mounted on the plug nose


26


and protrudes away from the plug body


22


at a slight angle, terminating at a narrow free end


30


. The retention clip


28


has retention notches


32


that define the edges where the retention clip


28


significantly narrows. Housed within the plug body


22


are distinct contact pins


34


. Each of the contact pins


34


is attached to a discrete wire within the cable


24


. During use, when the media plug


20


is inserted into the aperture


18


, the electrical contacts


42


of the extendable media connector


10


bias against the contact pins


34


of the media


20


, thereby providing an electronic link between the media plug


20


and the communications card device


12


via the extendable media connector


10


.




When a media plug


20


as described, is inserted into the aperture


18


of the extendable media connector


10


, retention tabs


44


latch onto the retention notches


32


of the retention clip


28


. This mechanically secures the media plug


20


within the aperture


18


. To remove the media plug


20


from the aperture


18


, the free end


30


of the retention clip


28


is flexed towards the body


22


of the media plug


20


. This releases the hold that the retention tabs


44


have on the retention notches


32


, allowing the media plug


20


to be freely removed from the aperture


18


.




In the preferred embodiment, the aperture


18


is configured to receive both RJ-11 and RJ-45 series media plugs


20


. It should be appreciated that this is a useful improvement over traditional sockets that can securely accommodate only a single type of media plug


20


. Traditional sockets that accommodate RJ-45 series plugs


20


must be at least as wide as the RJ-45 series plug body


22


, which is too wide to securely couple with the narrower RJ-11 series plugs


20


because the space between the socket walls and the body


22


of an RJ-11 series plug


20


allows the plug to wiggle back and forth. In contrast, a socket that is configured to securely accommodate an RJ-11 series plug


20


is too narrow to receive the body


22


of an RJ45 series plug


20


.




The present invention in one embodiment overcomes these problems by providing an aperture


18


that is wide enough to receive both RJ-11 and RJ-45 series media plugs


20


while providing alignment surfaces


46


that slidably engage the retention clip


28


of the media plug


20


, and align the media plug


20


within the aperture


18


. This alignment is secured when the retention tabs


44


of the frame


50


mechanically latch onto the retention notches


32


of the retention clip


28


, holding the media plug


20


securely in place. Apertures designed for only a specific dimension media plug are also contemplated within the scope of the present invention.





FIG. 3

illustrates a perspective view of one presently preferred embodiment of the extendable media connector


10


of the present invention. As shown, the extendable media connector


10


comprises a frame


50


. In this embodiment, the frame


50


comprises a rectilinear block


52


having an aperture


18


that extends therein. The aperture


18


is configured to receive the body


22


of an appropriate media plug


20


, as described above. During normal use, the frame


50


protrudes out of the communications card device


12


, as shown in

FIG. 3

so that a media plug


20


can be inserted into the aperture


18


. During normal nonuse, the frame


50


is slidably retracted into the housing of the communications card device


12


, as shown in FIG.


1


.




Although

FIG. 1

depicts an aperture


18


extending into the end of the frame


50


, this is only one possible location for the aperture


18


. In other embodiments, the aperture


18


extends into the side of the frame


50


, as shown in

FIG. 3

, to provide a means for sheltering the aperture


18


during nonuse so that it does not become a sink for the harmful accumulation of dust and debris. Dust and debris can be harmful when it accumulates within the aperture


18


and prevents the contact pins


34


of a media plug


20


from completing an electrical connection with the electrical contacts


42


of the extendable media connector


10


. The electrical contacts


42


are depicted in FIGS.


4


and


6


-


8


. Sheltering the aperture


18


during nonuse also proves to be beneficial for protecting the electrical contacts


42


from ancillary damage, such as electrical shorts and physical deformation. Damage and can occur, for example, when an object is inadvertently inserted into the aperture


18


during nonuse.




In the presently preferred embodiment, the frame


50


is rotatably mounted to the communications card device


12


and can freely rotate about a central axis


54


that extends through the center of the frame


50


. When the frame


50


is rotated about the central axis


54


then the aperture


18


is also forced to rotate about the same axis


54


. One of the benefits of having a frame


50


that can rotate is that it enables a media plug


20


to be coupled with the extendable media connector


10


from various angles. One reason this is useful is because it facilitates the insertion of a media plug


20


into the aperture


18


by providing a user with better visibility to the aperture


18


while inserting a media plug


20


into the aperture


18


. Another benefit is that a user can rotate the aperture


18


to the most convenient position for coupling with a media plug


20


. The most convenient position will vary, depending on personal preferences and environmental conditions. One practical example, illustrating the usefulness of having a rotating frame


50


, occurs when the extendable media connector


10


of the present invention is coupled with a media plug


20


that is attached to a very short cable


24


. The short cable


24


limits the mobility of the media plug


20


so that it can only be coupled with the extendable media connector


10


from certain angles of insertion. However, the rotatably mounted frame


50


can be rotated until the aperture


18


faces the media plug


20


, enabling the media plug


20


to be inserted into the aperture


18


, despite the constraints of the short cable


24


.




Another benefit of having a rotating frame


50


is to prevent or minimize damage to a cable


24


attached to a media plug


20


, the media plug


20


itself, and the extendable media connector


10


. For example, when an inadvertent force is applied to a cable


24


of a media plug


20


that is already coupled with a media connector


10


, tension is created that can break or deform the cable


24


, the media plug


20


, and the media connector


10


. However, if the frame


50


is free to rotate, as in the presently preferred embodiment, the frame


50


can provide slack to the cable


24


, minimizing the potential for damage.





FIG. 3

also illustrates a rotatable electrical interface that enables the extendable media connector


10


of the present invention to maintain an electrical connection between a media plug


20


and the communications card device


12


even when the frame


50


is being rotated. As shown, the rotatable electrical interface comprises a plurality of electrical tracks


60


that are mounted on a substantially flat surface of the back of the frame


50


. Each electrical track is attached to an individual electrical contact and a corresponding electrical brush of the communications card device


12


. When a media plug


20


is inserted into the aperture


18


, each contact pin of the media plug


20


is electronically connected to a corresponding electrical contact, electrical track, and electrical brush, thereby completing an electrical connection between the media plug


20


and the communications card device


12


.




Because the rotatable electrical interface is mounted to the frame


50


, electrical contact between the electrical tracks


60


and the corresponding electrical brushes


62


is maintained even when the frame


50


is rotated. Accordingly, the electrical connection between a media plug


20


and the communications card device


12


is not compromised by the functionality of rotatably mounting the frame


50


to the communications card device


12


.




As previously addressed, one of the benefits of the present invention is that the frame


50


can be slidably retracted into the housing of the communications card device


12


during nonuse to protect the aperture


18


and electrical contacts


42


from harmful dust and debris. However, before the frame


50


can be slidably retracted into the housing of the communications card device


12


, it must be aligned with a corresponding opening


64


in the housing of the communications card device


12


. It should be appreciated by one skilled in the art that detents or raised surfaces


61


can be formed in the frame


50


to aid a user in aligning the frame


50


with the opening


64


by providing a means for the user to feel differences in torque when rotating the frame


50


to know when the frame


50


is aligned with the opening


64


without having to visually inspect the alignment. When the frame


50


is aligned, it can be slidably retracted into the housing of the communications card. To prevent the electrical brushes


62


from being damaged, they are also retracted with the frame


50


.





FIG. 4

illustrates one alternative embodiment of the rotatable electrical interface of the present invention. In this embodiment, the rotatable electrical interface comprises an armature


70


having electrical tracks


60


disposed on a cylindrical shaft. As shown, the electrical brushes


62


rest on the electrical tracks


60


of the armature


70


, thereby maintaining electrical contact between the rotatable electrical interface and the electrical brushes


62


at all times, even when the frame


50


is rotated about the central axis


54


.





FIG. 5

illustrates another embodiment of the extendable media connector


10


of the present invention. In this embodiment, the frame


50


comprises a cylindrical block


72


that is rotatably mounted to a communications card device


12


. The cylindrical frame


50


rotates about a central axis


54


that extends through the center of the frame


50


. This embodiment may be preferred in some circumstances because the cylindrical block


72


frame


50


does not have to be rotated into a specific alignment with the opening


64


in the housing of the communications card device


12


before it is slidably retracted into the housing because the frame


50


and the housing have the same shape and are in perpetual alignment.




Also shown in

FIG. 5

, the rotatable electrical interface comprises a plurality of electrical tracks


60


that are disposed on a substantially flat surface and are in contact with corresponding electrical brushes


62


of the communications card device


12


. It should be appreciated, however, that the configuration of electrical tracks


60


and electrical brushes


62


can be modified without departing from the spirit of the present invention. For example, the electrical brushes


62


may be mounted on the frame


50


and the electrical tracks


60


may be mounted on the communications card device


12


, completely opposite of the depicted embodiment. Alternatively, as shown in

FIG. 6

, the electrical tracks


60


may be mounted on an armature


70


.





FIG. 7

illustrates yet another embodiment of the extendable media connector


10


of the present invention. In this embodiment, the frame


50


comprises a cylindrical block


76


that is rotatably mounted to a rectilinear block


74


that is slidably retractable into the housing of a communications card device


12


. An upper cover plate


80


and a lower cover plate


82


extend out of the rectilinear block


74


and cover the cylindrical block


76


, to protecting the cylindrical block when the frame


50


is extended. The cylindrical block


76


, mounted on the cover plates


80


and


82


of the rectilinear block


74


, can freely rotate around a central axis


54


that extends through the center of the cylindrical block


76


.




In this presently preferred embodiment, the rotatable electrical interface is located on the top surface of the cylindrical block


76


. The rotatable electrical interface comprises a plurality of electrical tracks


60


that are in contact with corresponding electrical brushes


62


of the communications card device


12


that are mounted on the slidably retractable rectilinear block


74


.




One benefit of this presently preferred embodiment is that a media plug


20


can be coupled within the aperture


18


of the frame


50


while the frame


50


is extended and can remain coupled within the aperture


18


when the frame


50


is slidably retracted within the housing of a communications card device


12


. This embodiment may be preferred by users who like the functionality of a slidably retractable frame


50


but do not want the frame


50


to extend away from the communications card device


12


after the media plug


20


has been inserted into the aperture


18


of the frame


50


for various reasons, such as aesthetics.




Using this embodiment, a user can initially extend the frame


50


away from the communications card device


12


to facilitate the insertion of a suitable media plug


20


into the aperture


18


of the frame


50


. After a media plug


20


has been inserted into the aperture


18


, the frame


50


can be slidably retracted into the housing of the communications card device


12


without removing the media plug


20


from the aperture


18


. It should be appreciated that even when the frame


50


is slidably retracted, it retains the benefits previously attributed to the present invention. In particular, the cylindrical block


76


can rotate, even while retracted, so as to provide slack when an inadvertent force is applied to a cable


24


of a media plug


20


that is mechanically secured within the aperture


18


, to minimize the potential for damage to the cable


24


, the media plug


20


, and the extendable media connector


10


.




During nonuse, after the media plug


20


is removed, the aperture


18


can be rotated behind the protective profile of the rectilinear block


74


so as to protect the aperture


18


and electrical contacts


42


from ancillary damage and the harmful accumulation of dust and debris. To assist a user in rotating the aperture


18


behind the protective profile of the rectilinear block


74


, the cylindrical


72


and rectilinear blocks


74


can be equipped with interacting irregular surfaces and detents


61


that enable the user to feel differences in torque, while rotating the cylindrical block


76


, that indicate when the aperture


18


is successfully positioned behind the protective profile of the rectilinear block


74


without requiring the user to make a visual confirmation.




In one variation of this presently preferred embodiment, shown in

FIG. 8

, the cylindrical block


76


is rotatably mounted to the rectilinear block


74


by a shaft


84


that extends between the upper and lower cover plates. In this embodiment, the electrical contacts


42


extend through the shaft


84


and terminate in electrical brushes


62


that make electrical contact with electrical tracks


60


that are located on the shaft


84


. The electrical tracks


60


are connected to contact wires that extend to the communications card device


12


through the shaft


84


, the cover plates and the rectilinear block


74


. Even though this example has gone into some detail regarding a specific configuration of electrical tracks


60


and electrical brushes


62


, it should be construed as merely illustrative. One skilled in the art will appreciate that there are various armature and commutator configurations that can be incorporated by the present invention without departing from the spirit of the present invention.




Accordingly, the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments are to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
