Description




FIELD OF THE INVENTION




The present invention relates generally to electrical connectors. More specifically, the present invention relates to electrical connectors such as jacks used in the telecommunications industry.




BACKGROUND OF THE INVENTION




Various electrical/fiberoptic connectors are known for use in the telecommunications industry to transmit voice, data and video signals. A common connector configuration includes a faceplate or outlet that is frequently mounted on a structure such as a wall. The faceplate defines a plurality of openings in which connectors can be mounted. A typical connector includes a modular jack defining a port sized for receiving a conventional 8 position modular plug. Other conventional types of connectors include SC connectors, ST connectors, BNC connectors, F connectors and RCA connectors.




With respect to electrical/fiberoptic connectors for the telecommunications industry, it is important that such connectors be easily installed, easily accessed after being installed and easily repaired. In this regard, it is desirable for the connectors to be front mounted within their corresponding faceplates. By front mounting the connectors, the connectors can be accessed without requiring their corresponding faceplates to be removed from the wall.




SUMMARY OF THE INVENTION




One aspect of the present invention relates to a jack including a jack housing having a front portion positioned opposite from a back portion. The front portion defines an inner chamber and also defines front and rear openings for accessing the inner chamber. The front opening comprises a port sized for receiving a plug. The rear portion of the jack housing defines an open channel that extends in a rearward direction from the front portion. The jack housing also includes a first comb that is secured to the jack housing within the inner chamber.




The jack also includes an insert assembly adapted to be secured to the jack housing. The insert assembly includes a connector mount having a first side positioned opposite from a second side. The connector mount includes two resilient locking tabs for securing the connector mount to the jack housing, a second comb positioned at the first side of the connector mount, and an insulation displacement terminal housing positioned at the first side of the connector mount. The insert assembly also includes a plurality of contact springs, and a plurality of insulation displacement terminals. The contact springs are separated by the second comb. Each of the contact springs includes a base end portion and a free end portion. The plurality of insulation displacement terminals are housed by the insulation displacement terminal housing. The insert assembly further includes a circuit board that provides electrical connections between the insulation displacement terminals and the contact springs. The circuit board is mounted at the second side of the connector mount.




The insert assembly is secured to the jack housing by orienting the insert assembly such that the circuit board is received within the open channel, and then sliding the insert assembly in a forward direction such that: one end of the insert assembly moves into the inner chamber of the jack housing through the rear opening of the jack housing; the locking tabs interlock with the jack housing; and the free end portions of the contact springs are received in the first comb.




Another aspect of the present invention relates to an insert for a jack. The insert includes a connector mount having a main body including a first side positioned opposite from a second side. The connector mount includes a snap-fit structure positioned at the main body for securing the connector mount to the jack. The connector mount also includes a divider positioned at the first side of the main body, and an insulation displacement terminal housing positioned at the first side of the main body. A plurality of contact springs are separated by the divider, and a plurality of insulation displacement terminals are housed by the insulation displacement terminal housing. A circuit board provides electrical connections between the insulation displacement terminals and the contact springs. The circuit board is mounted at the second side of the main body.




A further aspect of the present invention relates to a jack for use with a faceplate having a front side positioned opposite from a back side. The faceplate defines an array of jack openings. The jack includes a jack housing adapted to be mounted within a first one of the jack openings defined by the faceplate. The jack housing is sized and shaped to be inserted into the first jack opening from the front side of the faceplate. The jack housing includes a first retaining structure positioned opposite from a second retaining structure. The first and second retaining structures are positioned to engage the front side of the faceplate when the jack housing is mounted in the first jack opening. At least one of the first and second retaining structures includes spaced-apart retaining shoulders separated by a gap. Each of the retaining shoulders has a width w


s


that is larger than a width w


g


of the gap located between the retaining shoulders. The jack also includes a resilient cantilever member having a base end positioned opposite from a free end. The base end is integrally connected with the jack housing and the free end is positioned generally within the gap between the spaced-apart retaining shoulders. The cantilever member includes a retaining tab positioned near the free end of the cantilever member. The retaining tab is positioned to engage the back side of the faceplate when the jack housing is mounted in the first jack opening such that the faceplate is captured between the retaining shoulder and the retaining tab. The cantilever member has a width w


c


defined at the base end of the cantilever member. The total width w


t


of the jack housing is at least two times as large as the width w


c


.




Still another aspect of the present invention relates to a jack including a resilient cantilever member for retaining the jack within an opening of a faceplate. The resilient cantilever member includes a main body and wings that project transversely outward from opposite sides of the main body. The jack also includes deflection limiting surfaces positioned to engage the wings when the cantilever member has been deflected a first amount. Contact between the wings and the deflection limiting surfaces prevents the cantilever member from being overdeflected.




An additional aspect of the present invention relates to a jack including a jack housing defining a port sized for receiving a plug. The jack also includes a plurality of contact springs positioned within the housing. The contact springs include base end portions and free end portions. The jack further includes two separate and opposing comb structures for isolating the free end portions of the springs from one another. The opposing comb structures are relatively aligned so as to generally form closed ended slots in which the free end portions of the contact springs are received.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT





FIGS. 1A and 1B

show an example of a jack assembly


20


constructed in accordance with the principles of the present invention. The jack assembly


20


includes a faceplate


22


adapted to be fastened to a structure such as wall. For example, the faceplate


22


includes openings


23


for allowing the faceplate


23


to be bolted, screwed or otherwise connected to the wall.

FIG. 1A

shows a front side of the faceplate


22


adapted to face away from the wall, and

FIG. 1B

shows a back side of the faceplate


22


adapted to face toward the wall. Referring to

FIG. 1A

, the faceplate


22


defines two rectangular openings


24


positioned one above the other. Each of the openings


24


has a height h


o


and a width w


o


.




Referring still to

FIGS. 1A and 1B

, two modular jacks are shown mounted in each of the openings


24


of the faceplate


22


. For example, two straight jacks


26


are shown mounted in the lower opening


24


, and two angled jacks


26


′ are shown mounted in the upper opening


24


. The jacks


26


,


26


′ include front faces


28


,


28


′ that define poits


30


,


30


′ each sized for receiving a plug


32


(shown in FIG.


2


). A plurality of contact springs are positioned within each of the ports


30


,


30


′. The plugs


32


include resilient latches


33


. When the plugs


32


are inserted in the ports


30


,


30


′, the latches


33


interlock with front tabs


35


,


35


′ of the jacks


26


,


26


′ to retain the plugs


32


within the ports


30


,


30


′. To remove the plugs


32


, the latches


33


are depressed thereby allowing the plugs


32


to be pulled from the ports


30


,


30


′.




As shown in the illustrated preferred embodiment, the jacks


26


,


26


′ and the plugs


32


are eight contact type (i.e., four twisted pair) connectors. While the various aspects of the present invention are particularly useful for modular connectors, it will be appreciated that other types of connectors could also be used.




Referring to

FIGS. 3

,


4


and


7


A, one of the straight jacks


26


is shown. Generally, the straight jack


26


includes two basic components: a front jack housing


36


; and a rear insert assembly


38


. The jack housing


36


is adapted to be snap-fit into one of the openings


24


of the faceplate


22


. The insert assembly


38


is adapted to be snap-fit within the jack housing


36


. To mount the jack


26


in the faceplate


22


, the insert assembly


38


is first connected to the jack housing


36


, and then the jack


26


is inserted from the front side of the faceplate


22


into one of the openings


24


.




The jack housing


36


includes a front portion


40


positioned opposite from a back portion


42


. The front portion


40


of the jack housing


36


includes structure for securing the jack


26


to the faceplate


22


. For example, the front portion


40


includes a first retaining structure


44


positioned opposite from a second retaining structure


46


. Each of the retaining structures


44


,


46


includes spaced-apart retaining lips/shoulders


48


separated by a gap


50


. Each of the retaining shoulders


48


preferably has a width w


s


, and each of the gaps preferably has a width w


g


. It is preferred for each of the widths w


g


to be equal to or less than each of the widths w


s


. The widths w


s


and w


g


cooperate to define a total width w


t


of the jack housing


36


. The jack housing


36


also preferably includes a height h


j


defined between the first and second retaining structures


44


and


46


. It is preferred for the height h


j


to be larger than the height h


o


of the openings


24


defined by the faceplate


22


.




Referring to

FIG. 3

, the first retaining structure


44


includes a first resilient cantilever member


52


positioned between the retaining shoulders


48


of the first retaining structure


44


. Similarly, the second retaining structure


46


includes a resilient cantilever member


54


positioned between the retaining shoulders


48


of the second retaining structure


46


. Each of the cantilever members


52


,


54


includes a base end integrally formed with the jack housing


36


, and a free end positioned adjacent to the front face


28


of the jack


26


. Preferably, the free ends of the cantilever members


52


,


54


are flush or slightly recessed with respect to the front face


28


. Each of the cantilever members


52


and


54


also preferably has a width w


c


measured at the base ends of the cantilever members


52


,


54


. Preferably, the total width W


t


of the jack


26


is at least two times as large as the width w


c


. Such a size relationship assists in insuring that the cantilever members


52


,


54


can be easily flexed.




As shown in

FIG. 3

, the resilient cantilever member


54


includes a rear tab


56


adapted for engaging the back side of the faceplate


22


. Similarly, referring to

FIG. 5

, the resilient cantilever member


52


also includes a rear tab


58


for engaging the back side of the faceplate


22


. The cantilever member


52


further includes a front tab


60


for engaging the front side of the faceplate


22


. Additionally, it is noted that the cantilever member


52


at least partially defines a portion of the port


30


of the jack


26


. As a result, no portion of the jack housing


36


is provided for preventing the cantilever member


52


from being overflexed. To overcome this problem, the cantilever member


52


includes a pair of wings


62


(shown in

FIG. 5

) that project transversely outward from a main body of the cantilever member


52


. The wings


62


are positioned above recessed deflection limiting surfaces


64


formed on the jack housing


36


. When the cantilever member


52


has been flexed downward a predetermined amount, the wings


62


engage the deflection limiting surfaces


64


to prevent the cantilever member


52


from being overflexed.





FIG. 8

shows the jack


26


snap-fitted within the lower opening


24


of the faceplate


22


. As shown in

FIG. 8

, the upper and lower sets of retaining shoulders


48


engage the front side of the faceplate


22


to prevent the jack housing


36


from being pushed completely through the opening


24


. Similarly, the front tab


60


of the cantilever member


52


also engages the front side of the faceplate


22


. The rear tabs


56


,


58


of the cantilever members


52


,


54


engage the back side of the faceplate


22


to prevent the jack


26


from dislodging from the opening


24


. To mount the jack


26


within the opening


24


, the rear portion of the jack is inserted into the opening


24


. As the jack


26


is pushed into the opening


24


, ramped surfaces of the rear tabs


56


,


58


cause the cantilever members


52


,


54


to flex inward until the rear tabs


56


,


58


pass through the opening


24


. Once the rear tabs


56


,


58


have passed through the opening


24


, the cantilever members


52


,


54


snap outward thereby bringing the rear tabs


56


,


58


into engagement or opposition with the back side of the faceplate


22


. The entire jack


26


can be removed from the faceplate


22


by flexing the cantilever members


52


,


54


inward, and concurrently pulling the jack


26


from the opening


24


.




Referring again to

FIG. 5

, the front portion


40


of the jack housing


36


defines a inner chamber


66


for housing the contact springs


34


. The inner chamber


66


can be accessed through the front of the jack housing


36


via the port


30


, and also defines a rear opening


68


for allowing at least a portion of the insert assembly


38


to be inserted into the inner chamber


66


. Still referring to

FIG. 5

, a comb


70


is secured to the jack housing


36


within the inner chamber


66


. The comb


70


includes a plurality of dividers defining a plurality of slots. The slots are sized for receiving portions of the contact springs


34


such that the contact springs


34


are separated from one another. Guide rails


72


are positioned on opposite sides of the comb


70


. The guide rails


72


project into the inner chamber


66


from sidewalls of the jack housing


36


. The guide rails


72


each have a tapered vertical thickness such that the guide rails


72


are thicker adjacent the front side of the inner chamber


66


as compared to the rear side of the inner chamber


66


. Latch openings


74


are defined by the sidewalls of the jack housing


36


at locations above the guide rails


72


.




Referring still to

FIG. 5

, the back portion


42


of the jack housing


36


defines an open channel or trough


76


that extends in a rearward direction from the front portion


40


. The trough


76


is preferably sized to receive and support the insert assembly


38


when the insert assembly is connected to the jack housing


36


.




As shown in

FIGS. 3 and 4

, the insert assembly


38


includes a printed circuit board


78


, a connector mount


80


, the contact springs


34


, a plurality of insulation displacement terminals


82


, and a termination cap


84


. The contact springs


34


and the insulation displacement terminals


82


respectively include board contact portions


86


,


88


that extend through the connector mount


80


and engage respective contact locations


90


,


92


(e.g., plated through-holes) located on the printed circuit board


78


. The printed circuit board


78


includes a plurality of tracings


79


(only a representative one is shown) that electrically connect the contact locations


90


to the contact locations


92


. In this manner, the printed circuit board


78


provides electrical connections between the contact springs


34


and the insulation displacement terminals


82


.




The connector mount


80


preferably comprises a one-piece, plastic member having a main body


96


including a first side


98


positioned opposite from a second side


100


. The printed circuit board


78


is mounted at the second side


100


of the main body


96


. The first side


98


of the main body


96


is configured for holding or retaining the contact springs


34


and the insulation displacement terminals


82


. For example, the first side


98


of the main body


96


includes two combs


102


,


104


(shown in

FIG. 6

) for receiving and separating the contact springs


34


. Each of the combs


102


,


104


includes a plurality of dividers


103


defining slots sized for receiving the contact springs


34


.




The first side


98


of the main body


96


also includes an insulation displacement terminal housing


106


. The insulation displacement terminal housing


106


defines a plurality of slots


108


in which the insulation displacement terminals


82


are mounted. The slots


108


are sized to receive wires (not shown) desired to be terminated at the insert assembly


38


. The termination cap


84


is configured for pressing the wires (not shown) into the slots


108


such that the wires are connected to the insulation displacement terminals


82


. For example, the termination cap


84


includes a plurality of slotted walls


110


that fit within the slots


108


when the termination cap


84


is pressed down against the insulation displacement terminal housing


106


.




The connector mount


80


also includes two resilient locking tabs


112


integrally connected to the main body


96


for securing the insert assembly


38


to the jack housing


36


. The resilient locking tabs


112


include flexible lever members


114


positioned on opposite sides of the combs


102


,


104


. The locking tabs


112


are configured to snap within the latch openings


74


defined by the jack housing


36


to provide a snap-fit connection between the insert assembly


38


and the jack housing


36


. While the lever members


114


are shown connected to the main body


96


of the connector mount


80


, it will be appreciated that alternative snap-fit connecting structures could also be used. For example, the connector mount


80


could include holes, projections, or latches adapted to interlock with resilient tabs connected to the jack housing


36


.




To provide precise alignment between the insert assembly


38


and the jack housing


36


, the main body


96


of the connector mount


80


defines two slots


116


sized and positioned for receiving the guide rails


72


of the jack housing


36


. The slots


116


are formed within sidewalls of the main body


96


and are positioned on opposite sides of the combs


102


,


104


. Inner ends of the slots


116


are ramped to further enhance alignment between the jack housing


36


and the insert assembly


38


.




Referring to

FIG. 4

, the contact springs


34


each preferably includes a base portion


118


and a free end portion


120


. When the contact springs


34


are mounted on the connector mount


80


, the base portions


118


fit within the slots defined by the comb


102


, and the free end portions


120


are aligned above the slots defined by the comb


104


. Preferably, as shown in

FIG. 4

, adjacent springs


34


have non-parallel relationships with respect to one another to minimize crosstalk. A more detailed description relating to the spring configuration is provided by U.S. patent application Ser. No. 09/231,736, filed Jan. 15, 1999, which is hereby incorporated by reference.




To connect the insert assembly


38


to the jack housing


36


, the assembled insert assembly


38


(shown in

FIG. 7A

) is placed within the trough


76


of the jack housing


36


. For example, as shown in

FIG. 7B

, the insert assembly is positioned such that the circuit board


78


is received in the trough


76


, and the main body


96


of the connector mount


80


is supported by side walls


77


of the trough


76


(e.g., shoulders


79


of the main body


96


seat upon the tops of the side walls


77


). As so positioned, the printed circuit board


78


is vertically offset from the bed of the trough


76


.




Next, the insert assembly


38


is moved along the trough


76


in a forward direction such that a front end of the insert assembly


38


(e.g. the end at which the contact springs


34


are mounted) moves into the inner chamber


66


of the jack housing


36


through the rear opening


68


of the jack housing


36


. As the front end of the insert assembly


38


enters the inner chamber


66


, the guide rails


72


of the jack housing


36


are received within the guide slots


116


defined by the connector mount


80


. Also, the free end portions


120


of the contact springs


34


are received within the slots defined by the comb


70


located within the inner chamber


66


. When the insert assembly


38


has been fully inserted within the inner chamber


66


, the locking tabs


112


of the connector mount


80


snap within the latch openings


74


of the jack housing


36


. To remove the insert assembly


38


from the jack housing


36


, the locking tabs


112


can be depressed thereby allowing the insert assembly


38


to be pulled from the jack housing


36


.




It is significant that the guide rails


72


and the guide slots


116


provide for precise positioning of the connector mount


80


within the jack housing


36


. For example, the guide slots


166


and the guide rails


72


are configured to orient the connector mount


80


at a precise vertical and horizontal position relative to the comb


70


. At such a position, the springs


34


are received within the comb


70


, and the printed circuit board


78


is preferably offset from or held above the bed of the trough


76


. Because the board


78


is offset from the trough


76


, printed circuit boards having different thicknesses can be used without affecting the alignment of the connector mount


80


within the jack housing


36


. As a result, the alignment of the connector mount


80


within the jack housing


36


is not dependent upon the thickness of the circuit board


78


. Therefore, the rail and slot configuration eliminates variations in spring deflection and the resulting contact forces caused by tolerance variations in the thickness of the printed circuit boards.





FIG. 9

is a cross-sectional view taken along section line

9


of FIG.


8


. As shown in

FIG. 9

, when the insert assembly


38


is fully inserted within the jack housing


36


, the comb


70


secured with in the jack housing


36


and the comb


104


connected to the connector mount


80


oppose one another and are aligned generally along a common vertical plane. As a result, the combs


70


and


104


cooperate to form closed ended slots


122


in which the free end portions


120


of the contact springs


34


are received. Vertical spacing s between the combs


70


and


104


is preferably sufficiently small to prevent the fiee end portions


120


of the springs


34


from becoming displaced from the slots


122


. In this manner, the free end portions


120


of the springs


34


are captured between the two separate combs


70


and


104


.




The spring alignment feature provided by the combs


70


and


104


is important because the contact springs


34


typically have a center to center spacing of about 0.050 inches. When a plug is inserted into the port


30


, the plug engages the springs


34


causing the springs to deflect downwardly out of the comb


70


. Absent the two cooperating combs


70


and


104


, the springs can become misaligned and pushed into contact with one other during deflection. This is not surprising due to the relatively close spacing of the springs


34


. However, by capturing the springs


34


between the two combs


70


and


104


as described above, such misaligunment is prevented because the springs


34


always remain within their respective closed ended slots


122


during deflection.





FIGS. 10 and 11

illustrate one of the angled jacks


26


′. The angled jack


26


′ uses the same insert assembly


38


used by the straight jack


26


. Consequently, no further description of the insert assembly


38


will be provided. The angled jack


26


′ includes a jack housing


36


′ that is similar to the jack housing


36


described with respect to the straight jack


26


. However, the jack housing


36


′ has been modified to allow the jack


26


′ to mount at an angle relative to the faceplate


22


. For example, the jack housing


36


′ includes first and second retaining structures


44


′ and


46


′ for providing a snap-fit connection between the jack


26


′ and the faceplate


22


. The first and second retaining structures


44


′,


46


′ are preferably aligned along a line


124


that is oriented at an acute angle θ relative to the front face


28


′ of the jack


26


′. Consequently, when the jack


26


′ is secured to the faceplate


22


, the retaining structures


44


′,


46


′ cause the front face


28


′ of the jack


26


′ to be angled relative to the front face of the faceplate


22


.




The first retaining structure


44


includes two fixed retaining shoulders


126


(only one shown) positioned at opposite sides of the jack housing


36


′. Similarly, the second retaining structure


46


′ includes two spaced-apart retaining shoulders


128


positioned on opposite sides of the jack housing


36


′. A gap


130


separates the retaining shoulders


128


. A resilient cantilever member


132


is positioned within the gap


130


. The cantilever member


132


includes a rear stop


134


adapted to engage the back side of the faceplate


22


.




Referring to

FIG. 8

, when the jack


26


′ is mounted within the upper opening


24


of the faceplate


22


, the retaining shoulders


126


,


128


engage the front side of the faceplate


22


, while the rear stop


134


of the cantilever member


132


engages the back side of the faceplate


22


. To mount the jack


26


′ within the opening


24


, the rear portion of the jack is inserted into the opening


24


and the jack


26


′ is pushed into the opening


24


. As the jack


26


′ is pushed into the opening


24


, a ramped surface of the rear stop


134


causes the cantilever member


132


to flex upward until the rear stop


134


passes through the opening


24


. Once the rear stop


124


passes through the opening


24


, the cantilever member


132


snaps downward thereby bringing the rear stop


134


into engagement with the back side of the faceplate


22


. The entire jack


26


′ can be removed from the faceplate


22


by flexing the cantilever member


132


upward, and concurrently pulling the jack


26


′ from the opening


24


.
