Description




FIELD OF THE INVENTION




The present invention relates generally to a wire termination device for establishing an electrical connection with an insulated electrical connector. More particularly, the invention is an insulation displacement connector having a stuffer adapted for movement in a direction substantially parallel to the insulated electrical conductor.




BACKGROUND OF THE INVENTION




Electrical circuits, and in particular telecommunications networks, make extensive use of insulation displacement connectors to quickly and easily establish electrical connections with insulated electrical conductors. An insulation displacement connector typically includes a blade portion having a slot defining a pair of opposed, sharp edges that cut through the insulation of the insulated electrical conductor to establish electrical continuity between the insulation displacement connector and the electrical conductor. A stuffer exerts a mechanical advantage on the insulated electrical conductor to move the conductor into engagement with the insulation displacement connector. In telecommunications networks, insulation displacement connectors and stuffers are typically disposed within wire termination devices, such as line modules, protected terminal devices (PTDs), and station protectors, that establish the necessary electrical connections throughout the network. Electrical connections need to be established with, for example, the service provider (also referred to as “Telephone Company” or “Telco”) wires, the subscriber (also referred to a “drop”) wires, and jumper wires. A great number of wire termination devices are often housed in distribution enclosures, such as network interface devices (NIDs) and building entrance terminals (BETs), affixed to a wall of a building that have significant size and space limitations. As a result, the wire termination devices housed within the enclosure must be designed to be as small as possible, while still providing unobstructed access for a technician to establish the necessary electrical connections during both initial configuration and subsequent reconfiguration, for example, in the field.




It is known to provide an angled face on the stuffer so that a wire insertion channel formed in the wire termination device is readily visible to a technician when establishing an electrical connection between the insulation displacement connector and the insulated electrical conductor. The angled face of the stuffer permits the technician to clearly view the wire insertion channel as the insulated electrical conductor is inserted into the wire termination device. As previously mentioned, a mechanical advantage is necessary to move the insulated electrical conductor into contact with the opposed, sharp edges of the blade portion of the insulation displacement connector. A substantial mechanical advantage may be required to force the insulated electrical conductor into electrical contact with the insulation displacement connector, particularly when the conductor is a heavier gauge wire, such as 18 AWG copper. Accordingly, the mechanical advantage is typically provided by a screw that drives a movable portion of the stuffer against the insulated electrical conductor until the sharp edges of the blade portion of the insulation displacement connector cut through the insulation and the make electrical contact with the conductor. The stuffer screw is preferably positioned perpendicular to the insulated electrical conductor to obtain the greatest mechanical advantage. However, due to the aforementioned size and space limitations of the enclosure, unobstructed access to the stuffer screw and optimum visibility of the wire insertion channel is achieved when the wire insertion channel and the stuffer screw are both oriented in the line of sight of the technician. Heretofore, it has not been possible to position the wire insertion channel and the stuffer screw parallel to one another such that both are oriented in the line of sight of the technician.




Accordingly, it is apparent a need exists for a wire termination device that provides unobstructed access to the stuffer screw and optimum visibility of the wire insertion channel. It is further apparent that a particular need exists for an insulation displacement connector having a stuffer screw adapted for movement in a direction parallel to the insulated electrical conductor to thereby establish an electrical connection between the insulation displacement connector and the conductor.




SUMMARY OF THE INVENTION




A wire termination device is provided for establishing an electrical connection with an insulated electrical conductor. In one aspect of the invention, the wire termination device includes a first member and a second member that is movable relative to the first member between a first, unbiased position and a second, biased position. The second member includes means for stripping a portion of the insulation from the insulated electrical conductor when the second member moves from the first position to the second position. Accordingly, the second member is electrically disconnected from the insulated electrical conductor in the first position and is electrically connected both to the insulated electrical conductor and to the first member in the second position. Preferably, the means for stripping is a slot formed adjacent one end of the second member that defines a pair of opposed, sharp edges for stripping the insulation from the insulated electrical conductor.




In a preferred embodiment, the first member is fixed to the housing of the wire termination device by a conductive fastener. The second member includes a leg portion depending from and resiliently attached to the first member and a blade portion extending outwardly from the leg portion. The wire termination device further includes a stuffer having a cam surface that engages the second member. The stuffer is adapted for movement in a direction substantially parallel to the insulated electrical conductor and the second member is adapted for movement substantially perpendicular to the insulated electrical conductor. As the stuffer is moved downwardly, the cam surface forces the blade portion of the second member into engagement with the insulated electrical conductor. As the stuffer is moved upwardly, the blade portion disengages from the insulated electrical conductor and is returned to the first, unbiased position.




In another preferred embodiment, the first member includes a base portion, a leg portion depending upwardly from the base portion, and a blade supporting portion depending outwardly from the leg portion. The wire termination device further includes a guide attached to the first member. The guide is electrically connected to the first member and to the second member and the second member is movable relative to the guide between the first position and the second position. Preferably, the guide defines an elongate opening for receiving the second member therethrough and a pair of upper contacts disposed within the opening for slidingly engaging the blade portion of the second member. Similarly, the first member includes a lower contact for slidingly engaging the blade portion of the second member. As previously described, the wire termination device further includes a stuffer having a cam surface that engages the second member. The stuffer is adapted for movement in a direction substantially parallel to the insulated electrical conductor and the second member is adapted for movement in a direction substantially perpendicular to the insulated electrical conductor. As the stuffer is moved downwardly, the cam surface forces the blade portion of the second member into engagement with the insulated electrical conductor. As the stuffer is moved upwardly, the blade portion disengages from the insulated electrical conductor and is returned to the first, unbiased position.




In another aspect of the invention, a wire termination device is provided for establishing an electrical connection with an insulated electrical conductor. The wire termination device includes a housing defining an internal cavity and having a wire insertion channel formed therein that extends into the cavity. A portion of the insulated electrical conductor is disposed within the wire insertion channel. An insulation displacement corrector disposed within the cavity includes a first member fixed to the housing and a second member movable relative to the first member between a first, unbiased position and a second, biased position. The second member has a slot formed therein adjacent one end that defines a pair of opposed, sharp edges for stripping a portion of the insulation from the insulated electrical conductor when the second member moves from the first position to the second position. In the first position, the second member is electrically disconnected from the insulated electrical conductor. In the second position, the second member is electrically connected to the insulated electrical conductor and to the first member. The wire termination device further includes a stuffer disposed within the cavity for moving the second member between the first position and the second position. The stuffer is adapted for movement in a direction substantially parallel to the insulated electrical conductor and the second member is adapted for movement in a direction substantially perpendicular to the insulated electrical conductor.




In another aspect of the invention, a method is provided for establishing an electrical connection between an insulation displacement connector and an insulated electrical conductor. The insulation displacement connector is disposed within an internal cavity defined by the housing of a wire termination device. The insulation displacement connector includes a first member and a second member movable relative to the first member between a first, unbiased position and a second, biased position. The second member has a slot formed therein adjacent one end that defines a pair of opposed, sharp edges for stripping a portion of the insulation from the insulated electrical conductor when the second member moves from the first position to the second position. In the first position, the second member is electrically disconnected from the insulated electrical conductor. In the second position, the second member is electrically connected to the insulated electrical conductor and to the first member. The wire termination device further includes a stuffer for moving the second member between the first position and the second position.




In a preferred embodiment, the method includes the first step of positioning the insulated electrical conductor in a wire insertion channel formed in the housing and extending into the cavity defined by the housing of the wire termination device. The method further includes the second step of moving the second member in a direction substantially perpendicular to the insulated electrical conductor from the first position to the second position. In another preferred embodiment, the method includes the first step of positioning the insulated electrical conductor in a wire insertion channel formed in the housing and extending into the cavity defined by the housing of the wire termination device. The alternative preferred method further includes the second step of moving the stuffer in a direction substantially parallel to the insulated electrical conductor so that the second member moves from the first position to the second position.

DETAILED DESCRIPTION OF THE INVENTION




The present invention now will be described more fully hereinafter with reference to the accompanying drawings, in which preferred embodiments of the invention are shown. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, the preferred embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those of ordinary skill in the art. Like numbers refer to like elements throughout.




Referring now to the accompanying drawings,

FIGS. 1 and 2

show a wire termination device, indicated generally at


10


, according to a preferred embodiment of the invention. The wire termination device


10


is of a type commonly utilized in a distribution enclosure, such as a network interface device (NID) or building entrance terminal (BET), of a telecommunications network to establish an electrical connection with an insulated electrical conductor. For example, the wire termination device


10


may be a line module, a protected terminal device (PTD), or a station protector positioned within the enclosure to terminate service provider wires, subscriber wires, and jumper wires, and thereby electrically connect respective ones of the service provider wires with respective ones of the subscriber wires or jumper wires. A great number of the wire termination devices


10


are typically housed together in extremely close proximity to one another within a distribution enclosure having significant size and space limitations. As a result, it is imperative to provide sufficient access to each of the wire termination devices


10


so that a technician may establish the necessary electrical connections during both initial configuration and subsequent reconfiguration, for example, in the field.




The wire termination device


10


preferably comprises a housing


12


defining an internal cavity


14


(

FIGS. 4

,


5


,


7


and


8


). At least one, and preferably at least two, wire insertion channels


16


are formed in the housing


12


and extend into the internal cavity


14


. The wire insertion channels


16


receive an insulated electrical conductor


20


therein for establishing an electrical connection, as will be described. The insulated electrical conductor


20


preferably comprises an inner core made of a conductive material, such as copper wire, surrounded by an outer sheath of a non-conductive, insulating material, such as soft plastic. As known to those of ordinary skill in the art, the insulated electrical conductor


20


may be a service provider wire, a subscriber wire, or a jumper wire electrically connected, for example, to another electronic component within the enclosure. The insulated electrical conductor may have any diameter, but typically has a diameter of between about 18 and about 24 AWG. The wire termination device


10


further comprises a stuffer


18


for establishing the electrical connection with the insulated electrical conductor


20


. The stuffer


18


is preferably a conventional stuffer screw having a lower portion


17


, as described in greater detail hereinafter. However, the stuffer


18


may be any activating member for moving an insulation displacement connector as prescribed herein, including for example and without limitation, a plunger or a cam activated by a lever. As shown, the wire termination device


10


may also have one or more test ports


15


formed in the housing


12


that extend into the internal cavity


14


for testing the electrical continuity of the electrical connections in a known manner.




A preferred embodiment of an insulation displacement connector, indicated generally at


30


, adapted to be disposed within the cavity


14


of the wire termination device


10


is shown in FIG.


3


. The insulation displacement connector


30


is made of a conductive material, such as metal, and comprises a first member


32


and a second member


36


depending upwardly from the first member. The first member


32


is adapted to be fixed to the housing


12


of the wire termination device


10


and preferably has a hole


33


formed therethrough for receiving a fastener, such as a screw or rivet, to fix the first member to the housing. In the preferred embodiment shown in

FIG. 3

, the second member


36


comprises a leg portion


35


resiliently attached to the first member


32


and a blade portion


37


depending outwardly from the leg portion substantially parallel to the first member. The blade portion


37


of the second member


36


has a slot


38


formed therein that defines a pair of opposed, sharp edges for cutting the outer sheath of the insulated electrical conductor


20


, as will be described. The blade portion


37


further has an elongated relief


39


formed therein for permitting the slot


38


to open when the blade portion of the insulation displacement connector


30


engages the insulated electrical conductor


20


.




As previously mentioned, the leg portion


35


of the second member


36


is resiliently attached to the first member


32


. As such, the second member


36


is movable relative to the first member


32


between a first, unbiased position, shown in

FIG. 4

, and a second biased position, shown in FIG.


5


. In the unbiased position, the blade portion


37


of the second member


36


does not engage, and therefore, is electrically disconnected from the insulated electrical conductor


20


. However, because the second member


36


depends from and is resiliently attached to the first member


32


, the second member is electrically connected to the first member. In the biased position, the second member


36


engages the insulated electrical conductor


20


, and therefore, is electrically connected to both the insulated electrical conductor and to the first member


32


. Typically, the first member


32


is further electrically connected to a conductive member (not shown) so that the insulated electrical conductor


20


completes an electrical circuit between, for example, a service provider wire and a subscriber wire or a jumper wire in a known manner.




Preferably, the insulated electrical conductor


20


is disposed within the cavity


14


defined by the housing


12


of the wire termination device


10


. Similarly, the stuffer


18


of the wire termination device


10


is disposed within the cavity


14


defined by the housing


12


. Most importantly, a lower portion


17


of the stuffer


18


extends downwardly into the cavity


14


and the stuffer is adapted for movement in a direction parallel to the wire insertion channel


16


and the insulated electrical conductor


20


. The lower portion


17


of the stuffer


18


has a cam surface


19


angled relative to the leg portion


35


of the second member


36


. As such, the blade portion


37


of the second member


36


is forced into engagement with the insulated displacement conductor


20


as the cam surface


19


of the stuffer


18


travels downwardly against the leg portion


35


of the second member. In particular, as the lower portion


17


of the stuffer


18


is moved in the direction indicated by the vertical arrow, the blade portion


37


of the second member


36


is forced to move in the direction indicated by the horizontal arrow into a slot


13


formed in the housing


12


of the wire termination device


10


from the first, unbiased position (

FIG. 4

) to the second, biased position (

FIG. 5

) As a result, an electrical connection is established between the insulation displacement connector


30


and the insulated electrical conductor


20


.




In the event that the wire termination device


10


must be subsequently reconfigured by a technician, for example in the field, the electrical connection may be broken and the insulated electrical conductor


20


removed from the wire insertion channel


16


formed in the housing


12


in any number of ways that are well within the level of ordinary skill in the art. For purposes of example and not limitation, the leg portion


35


of the second member


36


may be provided with one or more outwardly extending flanges that cooperate with a channel or track formed on the cam surface


19


of the lower portion


17


of the stuffer


18


. Accordingly, the leg portion


35


of the second member


36


will ride in the track formed on the cam surface


19


as the stuffer


18


is moved downwardly and upwardly in a direction parallel to the wire insertion channel


16


, thereby causing the blade portion


37


of the second member


36


to move alternately into and out of engagement with the insulated electrical conductor


20


.




An alternative preferred embodiment of an insulation displacement connector, indicated generally at


40


, adapted to be disposed within the cavity


14


of the wire termination device


10


is shown in FIG.


6


. The insulation displacement connector


40


is made of a conductive material, such as metal, and comprises a first member


42


and a second member


46


that is movable relative to the first member. The first member


42


is adapted to be fixed to the housing


12


of the wire termination device


10


and preferably has a hole


43


formed therethrough for receiving a fastener, such as a screw or rivet, to fix the first member to the housing. In the preferred embodiment shown in

FIG. 6

, the first member


42


comprises a base portion


41


and a leg portion


45


depending upwardly from the base portion. As shown, the leg portion


45


is substantially perpendicular to the base portion


41


. However, the leg portion


45


may be positioned at any suitable angle relative to the base portion


41


required by the design constraints of the wire termination device


10


. The first member


42


further comprises a blade supporting portion


44


(

FIGS. 7 and 8

) depending outwardly from the leg portion


45


, for a purpose to be described. The second member


46


comprises a cam-engaging portion


50


and a blade portion


47


depending outwardly from the cam-engaging portion


50


. The blade portion


47


of the second member


46


has a slot


48


formed therein that defines a pair of opposed, sharp edges for cutting the outer sheath of the insulated electrical conductor


20


, as previously described. The blade portion


47


further has an elongated relief


49


formed therein for permitting the slot


48


to open when the blade portion of the insulation displacement connector


40


engages the insulated electrical conductor


20


.




The insulation displacement connector


40


further comprises a guide


52


that is positioned in an enlarged portion of the slot


13


formed in the housing


12


of the wire termination device


10


. The guide


52


has a groove or channel


53


formed therein for receiving the blade portion


47


of the second member


46


. As shown, the guide


52


is an elongated, generally hollow tube made entirely of a conductive material, such as metal. However, the guide


52


may have any suitable configuration required by the design constraints of the wire termination device


10


and may be made partially of a non-conductive material, such as plastic. In the preferred embodiment shown and described herein, the guide


52


has at least one, and preferably a pair, of upper contacts


54


(

FIGS. 7 and 8

) formed on the interior surface for slidingly engaging the upper surface of the blade portion


47


of the second member


46


. The lower surface of the blade portion


47


is slidingly supported by a rounded lower contact


55


(

FIGS. 7 and 8

) provided on the upper surface of the blade supporting portion


44


of the first member


42


. Accordingly, the blade portion


47


of the second member


46


is slidingly positioned within the guide


52


between the upper contacts


54


of the guide and the lower contact


55


of the first member


42


.




The guide


52


supports the blade portion


47


of the second member


46


in the slot


13


formed in the housing


12


such that the second member is movable relative to the first member


42


between a first, unbiased position, shown in

FIG. 7

, and a second biased position, shown in FIG.


8


. In the unbiased position, the blade portion


47


of the second member


46


does not engage, and therefore, is electrically disconnected from the insulated electrical conductor


20


. However, because the second member


46


is supported by the lower contact


55


of the first member


42


, the second member is electrically connected to the first member. In the biased position, the second member


46


engages the insulated electrical conductor


20


, and therefore, is electrically connected to both the insulated electrical conductor and to the first member


42


. Typically, the first member


42


is further electrically connected to a conductive member (not shown) so that the insulated electrical conductor


20


completes an electrical circuit between, for example, a service provider wire and a subscriber wire or a jumper wire in a known manner.




Preferably, the insulated electrical conductor


20


is disposed within the cavity


14


defined by the housing


12


of the wire termination device


10


. Similarly, the stuffer


18


of the wire termination device


10


is disposed within the cavity


14


defined by the housing


12


. Most importantly, a lower portion


17


of the stuffer


18


extends downwardly into the cavity


14


and the stuffer is adapted for movement in a direction parallel to the wire insertion channel


16


and the insulated electrical conductor


20


. The lower portion


17


of the stuffer


18


has a cam surface


19


angled relative to the cam-engaging portion


50


of the second member


46


. As such, the blade portion


47


of the second member


46


is forced into engagement with the insulated displacement conductor


20


as the cam surface


19


of the stuffer


18


travels downwardly against the cam-engaging portion


50


of the second member. In particular, as the lower portion


17


of the stuffer


18


is moved in the direction indicated by the vertical arrow, the blade portion


47


of the second member


46


is forced to move in the direction indicated by the horizontal arrow into the slot


13


formed in the housing


12


of the wire termination device


10


from the first, unbiased position (

FIG. 7

) to the second, biased position (FIG.


8


). As a result, an electrical connection is established between the insulation displacement connector


40


and the insulated electrical conductor


20


.




In the event that the wire termination device


10


must be subsequently reconfigured by a technician, for example in the field, the electrical connection may be broken and the insulated electrical conductor


20


removed from the wire insertion channel


16


formed in the housing


12


in any number of ways that are well within the level of ordinary skill in the art. For purposes of example and not limitation, the cam-engaging portion


50


of the second member


46


may be provided with one or more outwardly extending flanges that cooperate with a channel or track formed on the cam surface


19


of the lower portion


17


of the stuffer


18


. Accordingly, the cam-engaging portion


50


of the second member


46


will ride in the track formed on the cam surface


19


as the stuffer


18


is moved downwardly and upwardly in a direction parallel to the wire insertion channel


16


, thereby causing the blade portion


47


of the second member


46


to move alternately into and out of engagement with the insulated electrical conductor


20


.
