Abstract
The invention provides a latch release for engaging an operative portion of a latching mechanism of a connector to switch the latching mechanism between a latched position and an unlatched position. In one embodiment, a latch release is provided comprising a housing that is cooperatively associated with the connector so as to be positioned adjacent to the operative portion of the latching mechanism. A beam is pivotably supported by the housing and comprises a front end positioned adjacent to the operative portion of the latching mechanism and a rear end that is spaced from the operative portion of the latching mechanism. In this way, when the rear end of the beam is moved, the beam pivots so that the front end operatively engages the operative portion of the latching mechanism. In another embodiment of the invention, the latch release comprises a beam pivotably supported by the housing and comprising a front end positioned adjacent to the operative portion of the latching mechanism, a rear end that is spaced from the operative portion of the latching mechanism and a resilient hinge located between the front and rear ends. In this embodiment, when the rear end of the beam is moved, the beam pivots flexing the living hinge thereby moving the front end into operative engagement with the operative portion of the latching mechanism. In yet another embodiment of the invention, the latch release comprises a cam slidably supported by the housing and comprising a front end positioned adjacent to the operative portion of the latching mechanism and including a camming surface and a rear end that is spaced from the operative portion of the latching mechanism. In this embodiment, when the rear end of the cam is slid toward the latching mechanism the camming surface operatively engages the operative portion of the latching mechanism.
Description




FIELD OF THE INVENTION




The present invention generally relates to electrical connectors, and more particularly to devices adapted for the actuation of locking latches.




BACKGROUND OF THE INVENTION




Electrical connectors typically have a multiplicity of terminal contacts positioned in an insulating housing, and arranged so as to be connected to a complementary connector to form a connector pair. It is well known to use mechanical latching mechanisms for maintaining the connection between the two connectors. The latching mechanism will ensure that the mating connectors maintain an electrical connection. Typically, the connector includes an integral latch member which is secured to the housing by a leg or biased hinge, or a connection point with the housing of the connector. The mating connector has a catch or a lug which will engage the latch mechanism when the two connectors are interengaged thereby ensuring that the connectors remain secured together. Examples of connectors utilizing such devices may be found in U.S. Pat. Nos.: 6,089,898; 6,071,141; 5,947,776; 5,941,726; 5,785,540; 5,725,324; 5,399,109; 5,255,154; 5,207,593; 4,995,826; 4,647,128; and 4,272,145.




These arrangements are not always satisfactory, especially when they are used in conjunction with multiple, but separate connectors that are positioned either side-by-side or stacked one above the other.




There is a need in the art for connectors that can be released from one another when the latching mechanism is located in a remote position, or in an arrangement with other connector pairs that provides little or no space for actuation. This need in the art has become acute in connection with many “high density” interconnection systems, where unlatching must take place under difficult circumstances, e.g., in a blind space where several such connectors are arranged in a stacked configuration.




SUMMARY OF THE INVENTION




The present invention provides a latch release for engaging an operative portion of a latching mechanism of a connector to switch the latching mechanism between a latched position and an unlatched position. In one embodiment, a latch release is provided comprising a housing that is cooperatively associated with the connector so as to be positioned adjacent to the operative portion of the latching mechanism. A beam is pivotably supported by the housing and comprises a front end positioned adjacent to the operative portion of the latching mechanism and a rear end that is spaced from the operative portion of the latching mechanism. In this way, when the rear end of the beam is moved, the beam pivots so that the front end operatively engages the operative portion of the latching mechanism.




In another embodiment of the invention, a latch release is provided comprising a beam pivotably supported by the housing and comprising a front end positioned adjacent to the operative portion of the latching mechanism, a rear end that is spaced from the operative portion of the latching mechanism and a resilient hinge located between the front and rear ends. In this embodiment, when the rear end of the beam is moved, the beam pivots, flexing the living hinge, and thereby moving the front end into operative engagement with the operative portion of the latching mechanism.




In yet another embodiment of the invention, a latch release is provided comprising a cam slidably supported by the housing and comprising a front end positioned adjacent to the operative portion of the latching mechanism and including a camming surface and a rear end that is spaced from the operative portion of the latching mechanism. In this embodiment, when the rear end of the cam is slid toward the latching mechanism the camming surface operatively engages the operative portion of the latching mechanism.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT




This description of preferred embodiments is intended to be read in connection with the accompanying drawings, which are to be considered part of the entire written description of this invention. In the description, relative terms such as “horizonal,” “vertical,” “up,” “down,” “top” and “bottom” as well as derivatives thereof (e.g., “horizontally,” “downwardly,” “upwardly,” etc.) should be construed to refer to the orientation as then described or as shown in the drawing figure under discussion. These relative terms are for convenience of description and normally are not intended to require a particular orientation. Terms including “inwardly” versus “outwardly,” “longitudinal” versus “lateral” and the like are to be interpreted relative to one another or relative to an axis of elongation, or an axis or center of rotation, as appropriate. Terms concerning attachments, coupling and the like, such as “connected” and “interconnected,” refer to a relationship wherein structures are secured or attached to one another either directly or indirectly through intervening structures, as well as both movable or rigid attachments or relationships, unless expressly described otherwise. The term “operatively connected” is such an attachment, coupling or connection that allows the pertinent structures to operate as intended by virtue of that relationship.





FIGS. 1-6

show an electrical connector


5


that is terminated to the end of a cable


7


and supporting a latch release


10


formed in accordance with one embodiment of the present invention. More particularly, electrical connector


5


may comprise any of the well known high density interconnection devices that are known in the art. Connectors of this type typically include a plurality of closely spaced, electrically conductive pin or receptacle contacts (not shown) arranged within an insulative housing


11


, and individually terminated at one end to a corresponding plurality of conductors (not shown) that form the central portion of cable


7


. The electrical interconnection features of the plurality of closely spaced pin or receptacle contacts are positioned adjacent to an interface surface


14


of the connector.




Housing


11


of electrical connector


5


is typically formed from one of the well known polymer materials that are suitable for injection molding, e.g., polyhalo-olefins, polyamides, polyolefins, polystyrenes, polyvinyls, polyacrylates, polymethacrylates, polyesters, polydienes, polyoxides, polyamides, polycarbonates, polyterephthalates, and polysulfides and their blends, co-polymers and substituted derivatives thereof. Housing


11


also normally includes a resilient latch


16


having an operative portion positioned on an outer surface, and arranged to releasably engage a corresponding feature on a mating electrical connector (not shown) that may be, e.g., mounted on the edge of a printed wiring board or terminated to the end of another cable, or the like. Latch


16


may comprise various known shapes and include several alternative features that are adapted for releasably engaging a corresponding feature on the mating electrical connector, e.g., recesses, notches, shoulders, catches, or tabs, etc.

FIGS. 1-16

show a representative latch


16


that includes a catch


24


that is adapted to engage a corresponding recess, or the like (not shown) on a mating connector.




Typically, latch


16


will comprise a cantilevered beam that is fixed, via a living hinge


21


or the like. For example, in the embodiments shown in

FIGS. 1-16

, latch


16


extends rearwardly from interface surface


14


toward cable


7


, and at an acute angle relative to the top surface of housing


11


. In this way, depressing latch


16


toward the top surface of housing


11


stores elastic energy in living hinge


21


so that when released, latch


16


springs away from the top surface of housing


11


and toward its original unloaded position. Of course, the various embodiments of the latch release of the present invention, and their obvious variations, are not limited in any way to the latch arrangement shown in the figures, but may be advantageously used in connection with many other arrangements of latches and connectors.




Terminal end


26


of latch


16


may include various known features that are adapted for aiding in depressing latch


16


, and are arranged so that a finger


27


or tool may depress terminal end


26


to release latch


16


from engagement with the mating connector. For example, when connectors are mated together latch


16


may be depressed, thus disengaging catch


24


from a corresponding recessed portion (not shown) on the mating connector. However, due to the high density requirements placed on such connectors, little or no space is available for the application of a person's finger or tool to depress latch


16


and thereby release connector


5


from its corresponding mating connector, as intended by the design. This situation is often acute in applications that require a plurality of interconnection devices to be engaged to the same device in a closely spaced architecture, e.g., mounted both side-by-side and/or in stacked formation, and arranged with minimal clearance between adjacent connectors or other structures.




The present invention solves this problem in the art by providing latch release


10


that is adapted to slip over a rear portion of electrical connector


5


so as to provide an easily accessible means for engaging and depressing latch


16


of electrical connector


5


. More particularly, one embodiment of latch release


10


comprises a boot


30


having a first half


33


, a second half


35


, and a toggle beam


37


pivotably assembled between first and second halves


33


,


35


(FIG.


3


). First half


33


and second half


35


each comprise concavely shaped, complementary body portions that are typically formed from any of the well-known polymer materials disclosed hereinabove in connection with housing


11


of electrical connector


5


. Halves


33


,


35


are designed to mate along a peripheral edge


39


so as to form boot


30


. It has been found to be advantageous, although not required, to form boot


30


so as to be symmetric about a central dividing line (corresponding to peripheral edges


39


) so that halves


33


,


35


are mirror images of one another.




An internal recess


40


of halves


33


,


35


is shaped so as to be complementary with the outer profile of cable


7


and another internal recess


42


of halves


33


,


35


is shaped so as to be complementary with the outer profile of housing


11


of electrical connector


5


. In this way, when halves


33


,


35


are mated together to form boot


30


, i.e., brought into engagement with one another so that their respective peripheral edges


39


engage in aligned relationship, a central, open-ended passageway is formed within boot


30


that is sized and shaped to contain and cooperate with both a portion of housing


11


of electrical connector


5


and a portion of cable


7


. When assembled for use, boot


30


is positioned in overlying relation with electrical connector


5


and cable


7


so that a portion of cable


7


is located within internal recess


40


, and a portion of electrical connector


5


is located within internal recess


42


.




A cowl


45


projects from an outer surface of boot


30


, and is formed from cowlhalves


46


,


47


that are formed on corresponding outer surfaces of boot halves


33


,


35


, respectively. Cowl


45


comprises walls


49


,


50


and a radiused outer wall


53


. Through-bores


55


,


56


are formed in walls


49


,


50


at a position where they will be aligned in coaxial relation to one another when boot


30


is assembled from boot halves


33


,


35


. Cowl


45


defines a first open end


59


and a second open end


60


. First open end


59


is generally larger than second open end


60


, and is located adjacent to an open end of the central passageway within boot


30


that is formed by a portion of internal recess


42


. Second open end


60


is located between a portion of radiused outer wall


53


and an outer surface of boot


30


. As a result of this arrangement, when boot


30


is assembled to electrical connector


5


, a portion of terminal end


26


of latch


16


extends into first open end


59


and the interior of cowl


45


.




Referring to

FIGS. 4 and 5

, toggle beam


37


comprises an elongate beam having a first end


63


, a second end


66


, and a pivot axle


69


. More particularly, first end


63


includes an angled or radiused section


70


, that is sized and shaped for engagement with an operative portion of a tool or finger


27


. In the embodiment shown in

FIGS. 1-6

, first end


63


is radiused so as to curve outwardly relative to the longitudinal axis of toggle beam


37


and away from the outer surface of boot


30


. Second end


66


includes a latch engagement section


73


that is spaced from first end


63


and radiused section


70


by a substantially elongate and rigid section


76


. Pivot axle


69


comprises a substantially round shaft that projects outwardly from each lateral edge of toggle beam


37


, in perpendicular relation to rigid section


76


, and has a diameter sized to be received within through-bores


55


,


56


of cowl


45


. In the embodiment shown in

FIGS. 1-6

, pivot axle


69


is positioned eccentrically along section


76


of toggle beam


37


so as to be adjacent to a rear portion of latch engagement section


73


. Toggle beam


37


is assembled to boot


30


such that latch engagement section


73


is positioned within cowl


45


and adjacent to terminal end


26


of latch


16


, with pivot axle


69


rotatably positioned within through-bores


55


,


56


, and first end


63


and radiused portion


70


extending outwardly and away from second open end


60


of cowl


45


(FIGS.


4


and


5


).




In this way, when radiused portion


70


of toggle beam


37


is lifted, e.g., by sliding finger


27


or a tool between it and the outer surface of boot


30


, toggle beam


37


pivots about pivot axle


69


, thereby moving latch engagement section


73


downwardly into contact with terminal end


26


of latch


16


(FIG.


5


). As this occurs, latch


16


bends toward housing


11


of electrical connector


5


with elastic energy being stored in living hinge


21


. This action, in turn, tends to bias latch


16


outwardly, away from electrical connector


5


. With latch


16


disposed in this biased state, electrical connector


5


may be pulled from engagement with its mating connector (not shown). Thus the present invention allows for the easy actuation of latch


16


when electrical connector


5


is mated in a high density interconnection architecture, e.g., when mounted either side-by-side, in stacked formation, and/or in any combination with minimal clearance between adjacent connectors or other structures.




Various modifications to the present invention will become obvious to those skilled in the art upon review of the appended claims. For example, and now referring to

FIG. 6

, a boot retention means, such as shoulder


78


, may be formed in a portion of halves


33


,


35


, with a corresponding mating recess


79


formed in a portion of electrical connector


5


. In this way, a secure engagement between boot


30


and electrical connector


5


may be maintained. Additionally, it has been found to be advantageous to taper the rear portion of boot


30


, as shown in

FIG. 5

, so as to provide for clearance between finger


27


and boot


30


during actuation of toggle beam


37


. Also, it will be understood that although boot


30


has been described as being formed from halves


33


,


35


, a single piece boot may also be used without departing from the scope of the present invention. Of course, other structures and forms of retention feature and boot will be suggested by this disclosure to those skilled in the art, and may also be used in connection with the invention with equal effect.




Referring to

FIGS. 7-11

, an alternative embodiment of the present invention includes latch release


80


comprising a boot


82


having a first half


83


, a second half


85


, and a hinge-beam


87


. Hinge-beam


87


is operatively assembled between first and second halves


83


,


85


(FIGS.


8


and


9


). First half


83


and second half


85


are similar to halves


33


,


35


, inasmuch as each comprise concavely shaped, complementary body portions that are typically formed from any of the well-known polymer materials disclosed hereinabove in connection with housing


11


. Halves


83


,


85


are designed to mate along a peripheral edge


89


so as to form boot


82


. It has also been found to be advantageous, although not required, to form boot


82


so as to be symmetric about a central dividing line (corresponding to peripheral edges


89


) so that halves


83


,


85


are mirror images of one another.




An internal recess


90


of halves


83


,


85


is shaped so as to be complementary with the outer profile of cable


7


and another internal recess


92


of halves


83


,


85


is shaped so as to be complementary with the outer profile of electrical connector


5


. In this way, when halves


83


,


85


are mated together to form boot


82


, i.e., brought into engagement with one another so that their respective peripheral edges


89


engage in aligned relationship, a central, open-ended passageway is formed within boot


82


that is sized and shaped to contain and cooperate with both a portion of housing


11


of electrical connector


5


and a portion of cable


7


. When assembled for use, boot


82


is positioned in overlying relation with electrical connector


5


and cable


7


so that a portion of cable


7


is located within internal recess


90


, and a portion of electrical connector


5


is located within internal recess


92


.




A cowl


95


projects from an outer surface of boot


82


, and is formed from cowlhalves


96


,


97


that are formed on corresponding outer surfaces of boot halves


83


,


85


, respectively. Cowl


95


comprises walls


99


,


100


and an outer wall


103


. Through-bores


104


,


105


and


106


,


107


are formed in walls


99


,


100


at a position where through-bores


104


,


105


will be aligned in coaxial relation to one another and through-bores


106


,


107


will be aligned in coaxial relation to one another, when boot


82


is assembled from boot halves


83


,


85


. Cowl


95


defines a first open end


109


and a second open end


110


. First open end


109


is generally larger than second open end


110


, and is located adjacent to an open end of the central passageway within boot


82


formed by a portion of internal recess


92


. Second open end


110


is located between a portion of outer wall


103


and an outer surface of boot


82


. As a result of this arrangement, when boot


82


is assembled to electrical connector


5


, a portion of terminal end


26


of latch


16


extends into open end


109


and the interior of cowl


95


.




Hinge-beam


87


comprises an elongate beam having a first end


113


, a second end


116


, and a pair of pivot axles


119


,


120


. More particularly, first end


113


may be flat or may include an angled or radiused section, that is shaped and sized for engagement with an operative portion of a tool or finger


27


. In the embodiment shown in

FIGS. 7-11

, first end


113


is flat so as to extend outwardly relative to the longitudinal axis of hinge-beam


87


. Second end


116


includes a latch engagement section


126


that is spaced from first end


113


by a substantially elongate and semi-rigid section


130


. More particularly, a resilient, living hinge


133


is formed in a portion of semi-rigid section


130


in such a way that semi-rigid section


130


may be biased, upwardly or downwardly, with elastic energy being stored in living hinge


133


.




Pair of pivot axles


119


,


120


comprise substantially round shafts that project outwardly from the lateral edges of hinge-beam


87


in perpendicular relation to semirigid section


130


, and have a diameter sized to be received within through-bores


104


,


105


and


106


,


107


of cowl


95


, respectively. In the embodiment shown in

FIGS. 7-11

, pivot axles


119


,


120


are positioned in spaced relation to one another, and to living hinge


133


, so that pivot axle


119


is adjacent to a front portion of first end


113


and pivot axle


120


is adjacent to a rear portion of latch engagement section


126


. Hinge-beam


87


is assembled to boot


82


such that latch engagement section


126


is positioned within cowl


95


and adjacent to terminal end


26


of latch


16


, with pivot axles


119


,


120


rotatably positioned within through-bores


104


,


105


and


106


,


107


, and first end


113


extending through second open end


110


of cowl


95


(FIGS.


8


-


11


). In this configuration, it is often advantageous to locate through-bores


104


,


105


and


106


,


107


in off-set relation to one another, such that when hinge-beam


87


is mounted within cowl


95


, pivot axle


120


is raised relative to pivot axle


119


(FIGS.


7


and


8


).




Thus, when first end


113


of hinge-beam


87


is depressed, e.g., by sliding finger


27


or a tool over top of it and pressing toward the outer surface of boot


82


, living hinge


133


pivots upwardly, about pivot axles


119


,


120


, thereby moving second end


116


and latch engagement section


126


downwardly into contact with terminal end


26


of latch


16


(FIGS.


10


and


11


). As this occurs, latch


16


bends toward housing


11


of electrical connector


5


with elastic energy being stored in living hinge


21


. This, in turn, tends to bias latch


16


outwardly, away from electrical connector


5


. This alternative embodiment of the present invention allows for the easy actuation of latch


16


when electrical connector


5


is mated in a high density interconnection architecture, e.g., when mounted either side-by-side, in stacked formation, and/or in any combination with minimal clearance between adjacent connectors or other structures.




Referring to

FIGS. 12-16

, in a further alternative embodiment of the present invention latch release


150


comprises a boot


152


having a first half


153


, a second half


155


, and a slide


157


operatively assembled between first and second halves


153


,


155


(FIGS.


13


and


14


). First half


153


and second half


155


are similar to halves


33


,


35


and


83


,


85


, inasmuch as each comprise concavely shaped, complementary body portions that are typically formed from any of the well-known polymer materials disclosed hereinabove in connection with housing


11


. Halves


153


,


155


are designed to mate along a peripheral edge


159


so as to form boot


152


. It has also been found to be advantageous, although not required, to form boot


152


so as to be symmetric about a central dividing line (corresponding to peripheral edges


159


) so that halves


153


,


155


are mirror images of one another.




An internal recess


160


of halves


153


,


155


is shaped so as to be complementary with the outer profile of cable


7


and another internal recess


162


of halves


153


,


155


is shaped so as to be complementary with the outer profile of electrical connector


5


. In this way, when halves


153


,


155


are mated together to form boot


152


, i.e., brought into engagement with one another so that their respective peripheral edges


159


engage in aligned relationship, a central, open-ended passageway is formed within boot


152


that is sized and shaped to contain and cooperate with both a portion of housing


11


of electrical connector


5


and a portion of cable


7


. When assembled for use, boot


152


is positioned in overlying relation with electrical connector


5


and cable


7


so that a portion of cable


7


is located within internal recess


160


, and a portion of electrical connector


5


is located within internal recess


162


.




A cowl


165


projects from an outer surface of boot


152


, and is formed from cowlhalves


166


,


167


that are formed on corresponding outer surfaces of boot halves


153


,


155


, respectively. Cowl


165


comprises walls


169


,


170


and an outer wall


173


. A slot


175


is formed along a portion of peripheral edge


159


of outer wall


173


when boot


152


is assembled from boot halves


153


,


155


. Cowl


165


defines a first open end


179


and a second end


180


. First open end


179


is generally larger than second end


180


, and is located adjacent to an open end of the central passageway within boot


152


formed by a portion of internal recess


160


. Second end


180


may be open or closed, and is located between a portion of outer wall


173


and an outer surface of boot


152


. As a result of this arrangement, when boot


152


is assembled to electrical connector


5


, a portion of terminal end


26


of latch


16


extends through first open end


179


into the interior of cowl


165


.




Slide


157


comprises an elongate beam having a first end


183


, a second end


186


, and a push/pull tab


189


. More particularly, first end


183


may be rectangularly shaped or may have another cross-sectional shape that is complementary to the internal shape of cowl


165


. Second end


186


includes a latch engagement section


193


that is spaced from first end


183


by a substantially elongate and semi-rigid section


190


. Latch engagement section


193


includes a camming surface


196


comprising an inclined or radiused wall. In the embodiment shown in

FIGS. 12-16

, push/pull tab


189


projects outwardly from the top surface of slide


157


so as to extend through slot


175


of cowl


165


. When slide


157


is assembled to boot


152


, latch engagement section


193


is positioned within cowl


165


, with camming surface


196


positioned adjacent to terminal end


26


of latch


16


.




Thus, when first end


183


of slide


157


is moved forwardly, by pushing upon tab


175


with finger


27


or tool, slide


157


moves latch engagement section


193


into contact with terminal end


26


of latch


16


(FIGS.


13


,


15


and


16


). As this occurs, camming surface


196


engages and slides along terminal end


26


of latch


16


which causes latch


16


to bend toward housing


11


of electrical connector


5


with elastic energy being stored in living hinge


21


. This, in turn, tends to bias latch


16


outwardly, away from electrical connector


5


. Thus this alternative embodiment of the present invention allows for the easy actuation of latch


16


when electrical connector


5


is mated in a high density interconnection architecture, e.g., when mounted either side-by-side, in stacked formation, and/or in any combination with minimal clearance between adjacent connectors or other structures.




It is to be understood that the present invention is by no means limited only to the particular constructions herein disclosed and shown in the drawings, but also comprises any modifications or equivalents within the scope of the claims.
