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.
