Description




BACKGROUND OF THE INVENTION




The invention may include interrelated electrical connectors that are rotatable about an axis.




A personal computer system may be thought of as a general-purpose, single-user microcomputer that is designed to be operated by a person. A small and low cost personal computer (PC) may include a monitor connected to a computer, each of which may receive power from an ordinary outlet. In operation, the monitor accepts video signals from a graphic card within the computer over a cable assembly and displays this information on a screen.




A monitor generally is designed to sit on an ordinary office desk. In some office arrangements, the computer is disposed directly below the monitor wherein the computer itself resides on the office desk. Here, this low profile computer is referred to as a desktop computer that is part of a desktop personal computer system configuration and has a low profile. In another office arrangement, the computer stands upright on the floor with the cabling running to a monitor, where the monitor itself sits directly on the office desk. In this set up, the computer is referred to as a stand alone computer that is part of a stand alone personal computer system configuration.




In both the desktop configuration and the stand alone configuration, the cable assembly includes a cable that is attached to a connector. The connector is usually a fifteen to twenty four pin connector that is plugged into the graphic card.




SUMMARY OF THE INVENTION




The invention includes a cable assembly housing. The cable assembly housing may include a main shell that defines a first cavity. The main shell may have a collar. The cable assembly may also include a cable shell that defines a second cavity. The cable shell may have three necks, two of which are disposed inside the first cavity, and the third neck is extended outside the collar. The cable shell may rotate about an axis of the main shell such that the cable shell is set at a predetermined angle and position with respect to the main shell.




The invention also includes a cable assembly. The cable assembly may include a main shell that defines a first cavity. The main shell may have a collar. The cable assembly may also include a cable shell that defines a second cavity. The cable shell may have three necks, two of which are disposed inside the first cavity, and the third neck is extended outside the collar. The cable assembly may also include a plurality of wires disposed through the second cavity. The plurality of wires may be divided into two bundles. The cable assembly may also include an electromagnetic interference shield. The electromagnetic interference shield may have two back openings to accept two bundles of wires.

FIGS. 2A and 2B

illustrate a cable assembly


200


and a cable assembly


201


respectively. Cable assembly


106


of FIG.


1


A and

FIG. 1B

may be based on cable assembly


200


or cable assembly


201


. Cable assembly


200


may be thought of as a Plug and Display cable assembly and cable assembly


201


may be thought of an improved or modified Plug and Display cable assembly. A cable assembly


200


and a cable assembly


201


are similar except for the differences highlighted below.




Cable assembly


200


and a cable assembly


201


may include a cable


202


and a connector


204


. Cable


202


may include a plurality of wires


206


, shield


208


, and jacket


210


. Each of the wires


206


may be a metallic strand or rod that is electrically insulated so as to safely and separately conduct electricity. Although there may be any number of wires


206


, in one embodiment, the number of wires


206


ranges from seventeen to twenty four.




Electricity traveling through each wire


206


may generate an electromagnetic field. Where not curbed, this electromagnetic field may interfere with video images, such as those appearing on a monitor


102


of FIG.


1


A. In one embodiment, a shield


208


may be disposed about wires


206


. Shield


208


may be metallic strand that are braided into a tube shape so as to confine any electromagnetic field generated by wire


206


within the interior of shield


208


. Shield


208


may also serve as a ground conductor. Moreover, jacket


210


may be disposed about a shield


208


as an insulator.




Connector


204


may include posts


212


, cover


214


, connector shell


216


, and flange


218


. Posts


212


may provide an electrical pathway between wires


206


and, for example, a graphics card


110


of FIG.


1


A. Posts


212


may either be male or female pins that are supported by flange


218


. Each wire


206


may be connected to an assigned post


212


within a cover


214


. Cover


214


may serve to enclose wires


206


as well as the connection point between wires


206


and posts


212


.




In one embodiment, (FIG.


2


A), connector shell


216


may enclose the mating end of post


212


, include keys


220


and be mounted against flange


218


. Along with keys


220


, the asymmetrical shape of connector shell


216


may provide orientation and insertion guidance for connector


204


with respect to graphics card


110


. Where flange


218


includes mounting holes


222


, screws may be disposed through the mounting holes


222


and into chassis


154


or graphics card


110


so as to secure connector


204


to a structure.




In another embodiment, (FIG.


2


B), connector shell


216


replaces connector shell


240


. Connector shell


216


may include notch


250


. Connector shell


240


may enclose the mating end of posts


212


, and be mounted against flange


218


. Since shell


240


is symmetrical otherwise (without notch


250


), notch


250


may provide orientation and insertion guidance for connector


204


with respect to graphics card


110


. Instead of including mounting holes


222


, flange


218


includes slits


230


. Instead of including screws, connector


204


includes quicklatches (not shown in

FIG. 2B

, details to be followed below). Quicklatches may be disposed through slits


230


and into chassis


154


or graphics card


110


so as to secure connector


204


to a structure.




Where wires


206


exit from a jacket


210


and enter a cover


214


, the electromagnetic field caused from these wires


206


may be free to interfere with local electronics. To prevent this, connector


204


may further include an Electromagnetic Interference (EMI) shield


224


. As a metal structure, an EMI shield


224


may provide a seal between jacket


210


and the EMI shield


224


.




Housing


226


may be disposed about connector


204


and portions of cable


202


. Housing


226


and connector


204


are discussed in connection with the remainder of the figures. Connector


204


and cable


202


may be thought of as interrelated electrical connectors. In this sense, housing


226


may permit relatively movement between a connector


204


and cable


202


so that a cable assembly, such as a cable assembly


200


and cable assembly


201


may serve as a cable assembly


106


of FIGS.


1


A and FIG.


1


B.




According to this invention, an articulating connector is a cable assembly that is capable of rotational movement. To achieve this feature, cable


202


may be housed in the housing


300


(see discussion below). Housing


300


may enable dressing of a cable at more than one angle, for examples, at one hundred-eighty-degrees and ninety-degrees. One advantage of having an articulating connector is that different computer systems have different space and connection constraints that determine the dressing requirements of the cable. The articulating connector meets various dressing requirements.





FIG. 3

illustrates one embodiment of the invention, housing


300


. Housing


300


may include a main shell


302


and a cable shell


304


. Main shell


302


may have the interior material removed to form a first cavity


320


. Cable shell


304


may also have the interior material removed to form a. second cavity


306


. In one embodiment, main shell


302


is formed in a single piece having a collar


324


. It is through collar


324


that cable shell


304


is disposed. Cable shell


304


may be a T-shaped joint comprising three necks (not shown in

FIG. 3A

) and when cable shell


304


is disposed within main shell


302


, only one neck extends outside main shell


302


. Cable shell


304


may rotate about an axis of main shell to provide cable dressing in different angles and positions. It will be appreciated that this articulating connector may be used for various types of computer interfaces, including video interfaces, USB interfaces, Firewire interfaces, and Peripheral Component Interconnect (PCI) interfaces, etc.





FIG. 4A

illustrates that cable shell


304


may also include top cable shell piece


418


which is coupled to bottom cable shell piece


420


. Cable shell


304


may also include mating surfaces


410


and


412


, necks


402


,


404


, and


406


, flanges


414


and


416


, and slots


422


.




As mentioned above, cable shell


304


may have the interior material removed to form second cavity


306


. Second cavity


306


may be a hollow area within the body of cable shell


304


that permits wires, such as those of cable


202


(FIGS.


2


A-B), to be disposed within and through cable shell


304


. Cavity


306


may have a circular or cylindrical perimeter. In one embodiment, each of necks


402


,


404


and


406


includes a circular perimeter.




As mentioned above, cable shell


304


may be a T-shaped joint including three necks; they are: a first neck


402


, a second neck


404


and a third neck


406


as illustrated in FIG.


4


A. When cable shell


304


is disposed within main shell


302


, first neck


402


and second neck


404


are the ones being disposed through collar


324


. Neck


406


extends outside collar


324


and it is through neck


406


that a cable such as cable


202


of

FIGS. 2A-B

, will first be inserted into housing


300


.




In a preferred embodiment, first neck


402


is disposed between first mating surface


410


and first flange


414


. Similarly, second neck


404


is disposed between second mating surface


412


and second flange


416


. (See FIG.


4


). Each of mating surfaces


410


and


412


may be the outer or topmost boundary of each side arm of cable shell


304


where necks


402


and


404


are located. Each mating surface serves as one of a matched pair of surfaces that comes together at interface


340


and


341


depicted in FIG.


3


. Each of necks


402


and


404


may be a narrow ring that elevates a flange, either flange


414


or flange


416


, above a mating surface so as to form a protruding rim. With its protruding and tapered rim, flange


414


and flange


416


may be used to hold cable shell


304


against main shell


302


as well as provide clearance for wires


206


.





FIG. 4B

illustrates that in one embodiment, neck


402


and neck


404


are disposed inside main shell


302


such that cable shell


304


can rotate about an axis of main shell


302


. It may be desirable to control or limit the rotation of cable shell


304


as it rotates about an axis of main shell


302


. Thus, cable shell


304


may be designed so as to allow the cable shell


304


to rotate to a predetermined angle and then lock into main shell


302


. To achieve this, cable shell


304


is designed with at least one slot


422


. Slot


422


is defined into an outer surface of cable shell


304


and extending axially along this outer surface. Each slot


422


may serve as a stop that limits or locks the rotational movement of cable shell


304


relative to main shell


302


.




In another embodiment, cable shell


304


is designed with two of slots


422


. In this example, cable shell


304


may rotate and lock into two different positions and angles. For example, one slot


422


may be located at a ninety-degree angle to another slot


422


. In that design, cable shell


304


can be rotated and then locked into either a one hundred-eighty or a ninety-degree angle relative to main shell


302


. (See

FIG. 4C and 4D

respectively). A button on the main shell


302


may be depressed to release the lock and allow cable shell


304


to rotate between these angular positions.





FIG. 4B

also illustrates that in a preferred embodiment, main shell


302


includes a first main shell piece


352


which can be coupled to a second main shell piece


354


. A crystal cap


330


depicted in

FIG. 3

may be disposed over first and second main shell pieces


352


and


354


so as to secure the coupling of the first and second main shell pieces. (See FIG.


3


).





FIG. 4B

also shows that in one embodiment, first main shell piece may include a detent


430


protruding out from the edge of collar


324


. Detent


340


may be a pawl or a hinge that engages slot


422


so as to facilitate the locking or limitation of the rotational movement of cable shell


304


about an axis of main shell


302


. Detent


340


may have thickness and dimension such that it enables sufficient locking or limiting while still facilitating easy release of cable shell. Where cable shell


304


is coupled to main shell


302


, detent


430


may engage slot


422


to provide a limit on the rotation between cable shell


304


and main shell


302


. With detent


430


, cable shell


304


may rotate about an axis of main shell


302


and lock into a position along the axis to form a predetermined angle, such as one hundred-eighty or ninety-degree, with main shell


302


.




As mentioned above, main shell


302


may have interior material removed to form first cavity


320


. Cavity


320


may be a hollow area within the body of main shell


302


that permits wires and a connector, such as those of cable


202


(FIGS.


2


A-B), to be disposed at least one of within and through main shell


304


. Cavity


320


may have a perimeter of any suitable shape, for example, circular, oblong, square, rectangular or oval.





FIG. 4B

illustrates that in one embodiment, collar


324


may include mating surfaces


440


and


442


on first main shell piece


352


and mating surfaces


444


and


446


on second main shell piece


354


. Mating surfaces


440


and


444


may be the outer or topmost boundary of one side of collar


324


that serves as the one of the matched pair of surfaces that comes together at interface


340


in FIG.


3


A. And, mating surfaces


442


and


446


may likewise be the outer or topmost boundary of another side of collar


324


that serves as the one of the matched pair of surfaces that comes together at interface


341


. Collar


324


may be an inwardly extending ring that forms an open space having a perimeter that is large enough to surround cable shell at neck


402


and


404


while leaving neck


406


extending outward from main shell


302


.





FIG. 5

illustrates that in an alternative embodiment, first main shell piece


352


may include first orifice


502


and that second main shell piece


354


may include second orifice


504


. In this embodiment, collar


304


is formed when first main shell piece


352


and second main shell piece


354


are coupled together allowing orifice


502


and orifice


504


to unite thereby forming the collar


324


.





FIG. 5

also illustrates that each of orifices


502


and


504


may also include three edges creating a U-shaped orifice in which two of the edges are running parallel to each other. For example, as illustrated in

FIG. 5

, orifice


502


includes edges


506


,


508


and


510


in which edges


508


and


510


are running parallel to each other. Similarly, orifice


504


includes edges


512


,


514


and


516


in which edges


514


and


516


are running parallel to each other. In one embodiment, edge


508


unites with edge


516


to form a mating surface that serves as a match for first mating surface


410


. Similarly, edge


510


unites with edge


514


to form a mating surface that serves as a match for second mating surface


412


. When all the mating surfaces mate, cable shell


304


is disposed within main shell


302


at interfaces


340


and


341


. (See also FIGS.


3


A and


4


B).




In another embodiment, a boss is coupled to each of the parallel edges. For example, boss


518


is coupled to edge


508


, boss


520


is coupled to edge


510


, boss


522


is coupled to edge


514


and boss


524


is coupled to edge


516


. Four Bosses


518


,


520


,


522


and


524


function to support cable shell


304


at necks


402


and


404


and allowing cable shell


304


to rotate smoothly within main shell


302


. In this embodiment, the four bosses also act as the mating surfaces that match up with mating surfaces


410


and


412


.





FIGS. 4B and 6

illustrate that to assemble housing


300


, first main shell piece


352


may be brought into contact with second main shell piece


354


with flanges


414


and


416


disposed within first cavity


320


. First main shell piece


352


then may be secured to second main shell piece


354


by employing methods such as sonic welding, or by applying adhesives. A crystal cap


330


may then be disposed over the first main shell piece


352


and the second main shell piece


354


securing the coupling of these two pieces. With main shell


302


formed, mating surfaces


440


and


444


may meet mating surface


410


and mating surfaces


442


and


446


may meet mating surface


412


of cable shell


304


as depicted in FIG.


4

FIGS. 4C

displays main shell


302


at a one hundred eighty-degree orientation to cable shell


304


. Such an orientation may be sufficient to employ in personal computer system


100


of FIG.


1


B.

FIG. 4D

displays main shell


302


at a ninety-degree orientation to cable shell


304


. Such an orientation may be sufficient to employ in personal computer system


150


of FIG.


1


A.




Cable shell


304


may be made from any thermoplastic that presents a high-impact strength, such as a polycarbonate. Main shell


302


may be made of any material that is different or dissimilar from cable shell


304


to minimize or prevent galling. Galling is a process where similar material rubbing surfaces are damaged by friction and abrasion. In one embodiment, main shell


302


includes acrylonitrile butadiene styrene (ABS), such as in polycarbonate ABS (PC/ABS). Where first main shell piece


352


is ultrasonically welded to second main shell piece


354


, cable shell


304


may be made of a material that resists the heat of this ultrasonic welding process.




To assemble cable assembly


200


into housing


300


,

FIGS. 5-6

illustrate that cable


202


may be disposed through second cavity


306


and first cavity


320


. Once cable


202


is disposed in side cavity


320


, connector


204


may then be attached to cable


202


as shown in

FIGS. 2A-B

. An electromagnetic interference (EMI) shield


224


may be disposed over the connector


204


to prevent electromagnetic interference caused by the wires


206


inside the cable


202


as discussed above in relation to

FIGS. 2A-B

. Due to the movement of cable


202


with respect to connector


204


, a rigid EMI shield


224


may cause damage to wires


206


. In one embodiment, a flexible EMI shield


224


may be disposed at the juncture between wires

may be disposed within adhesives, such as paste, mucilage, glue, or epoxy.





FIG. 7

illustrates that one unique feature about the cable assembly according to this invention is the splitting of the bundle of wires into two bundles.




Generally, according to this invention, cable wires enter into the housing in a single bundle of wires and are then split into two bundles of wires. Each bundle of wires is then routed into two separate paths through each side of the connection path between the connector portion and cable shell portion. Splitting the bundle of cable wires into two bundles may avoid having to bend a full thickness of cable wires. This is a significant advantage in a compact connector that has reduced space requirements and hence making accommodating the bending of large cable difficult. Bending two separate smaller bundles facilitates the making of the overall connector portion length compact.




As depicted in

FIG. 7

, in one embodiment, cable


202


, having a plurality of wires, enters neck


406


of cable shell


304


as one bundle. Once inside cable shell


304


, cable


202


is divided into two bundles of wires,


710


and


712


. Each of bundles


710


and


712


is then routed through either neck


402


or


404


. In this embodiment, it is preferred that cable shell


304


be made out of a top cable shell piece


418


and a bottom cable shell piece


420


describe above in

FIG. 4A

for ease of splitting the wires. In that instance, wires


206


would be placed on a bottom cable shell piece


420


and then be split into bundles


710


and


712


. Follow that, top cable shell piece


418


may then be brought into contact with the bottom cable shell piece


420


thereby forming cable shell


304


in which, bundles


710


and


712


are inserted.




Once divided, wires


206


are no longer covered by a jacket


210


or shield


208


and may be prone to cause electromagnetic interference. It is thus desirable to insulate bundles


710


and


712


with flexible EMI shield (not shown) to prevent electromagnetic interference. This flexible shield may be a soft copper sheet or a flexible conductive shrink tube wrapping around bundles


710


and


712


. This flexible shield Wires in each of bundles


710


and


712


may then be connected to posts


212


shown in

FIGS. 2A-B

.




In one embodiment, EMI shield


224


includes two back openings


714


and


716


. (See FIG.


7


). Each of bundles


710


and


712


may be inserted through either back openings


714


or


716


and be disposed through EMI shield


224


.




EMI shield


224


may include a top shield piece


802


coupled to a bottom shield piece


804


(See

FIG. 8-1

and


8


-


2


). EMI shield


224


may couple to connector shell


806


. Connector shell


806


would replace shell


220


of

FIG. 2A

or shell


240


of FIG.


2


B.




One advantage of splitting cable wires


206


according to this invention is that more wires can be inserted into connector


204


. According to this invention, it may be advantageous to include more than one type of cable wires in cable assembly


300


. For instance, a connector


204


may include both power signals and video signals for connecting a monitor to a CPU (Central Processing Unit). In such case, it may be important to differentiate between the traditional Plug and Display connector


200


shown in

FIG. 2A

from the improved connector


201


shown in FIG.


2


B. Mixing up the improved connector


201


with the traditional Plug and Display connector


200


could potentially result in applying power to the wrong pins


212


thus, causing damages to the unit being connected to. To achieve this purpose, shell


806


of the improved connector


201


may have a different shape as compared to the traditional plug and display connector


200


.




In one embodiment, connector shell


806


has a “racetrack” or a lozenge” shape which is essentially oval or oblong. (See

FIGS. 2

,


4


C and


4


D). It may be desirable, according to this invention, to include a notch


250


on one side of connector shell


806


to facilitate in direction of insertion. Notch


250


may act as a key located on one side of shell


806


to provide orientation and insertion guidance for connector


204


.




In one embodiment, cable assembly


300


may also include two quicklatches


358


as illustrated in FIG.


6


. Each of quicklatches


358


may extend from connector shell


806


to the distal end portion of main shell


302


. Alternatively, each quicklatches


358


may have a length that may be defined by a distance between connector shell


806


and cable shell


304


. Cable assembly


300


may further include flange


218


having two slits


230


(slits illustrated in FIG.


2


A-B). One quicklatch


358


may be inserted through one of slits


230


and the other quicklatch


358


, through the other slit


230


. Once assembled, these two quicklatches


358


may latch onto a structure. In this way, the traditional screwing mechanism needed to keep a connector in good contact with a structure is replaced by the latching mechanism of quicklatches


358


.




Preferably, cable assembly


300


should include two buttons


610


as illustrated in FIG.


6


. Buttons


610


may be partially embedded, one on each side, of main shell


302


. Buttons


610


functions as releasing mechanism whereby when buttons


610


are depressed, quicklatches


358


may move to release or detach connector


204


of cable assembly


300


from a structure.




For economic and other reasons, it may be desirable to be able to use the same cable assembly design for both the desktop configuration as shown in FIG.


2


A and the stand alone configuration as shown in FIG.


2


B. Accordingly, it may be desirable to have a cable assembly where the connector is rotatable about an axis of the cable.
