Abstract
A lever-type connector assembly has mating female and male connectors (10, 50). The female connector (10) has a lever (40) with a cam plate (41) and a resilient lock (46) that is deformable within the plane of the cam plate (41). The resilient lock (46) engages a receiving portion (33A) on the female connector (10) for holding the lever (40) at an initial position. The connector (50) has an unlocking rib (55) that deforms the resilient lock (46) out of engagement with the receiving portion (33A). As a result, the lever (40) can rotate for connecting the connectors (10, 50). Since the resilient lock (46) deforms in the plane of the cam plate (41), there is no need to provide space for deformation of the resilient lock (46) along a thickness direction of the cam plate (41).
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a lever-type connector assembly.
2. Description of the Related Art
A lever-type connector assembly has first and second connectors that can be connected together. The first connector has a housing and a lever is mounted on the housing. The lever typically is U-shaped and has two cam plates connected by an operable portion. Each cam plate is mounted rotatably on a supporting shaft provided at the left and right side surfaces of the housing. Thus, the lever is located right outside the left and right sides of the housing. Each cam plate also is formed with a cam groove. Cam pins project from the second connector and engage the cam grooves of the lever. The lever can be rotated in this state and the two connectors are pulled toward each other and connected by the cam action of the cam grooves and the cam pins.
The lever of the above-described connector assembly must be held at an initial stage where the cam grooves of the lever are in a position for receiving the cam pins. To this end, a lever-type connector assembly disclosed, for example, in U.S. Pat. No. 5,876,225 is constructed such that each cam plate has a projection engageable with a housing. The lever is held at an initial position by engaging the projections with the housing. The projections and the housing are engaged with and disengaged from each other by resiliently deforming the cam plates along the thickness direction of the cam plates.
The connector assembly described above occasionally must be made smaller in a direction of the rotational axis of the lever, which is the thickness direction of the cam plates. However, the conventional connector assembly needs to ensure a space for permitting the resilient deformation of the cam plates in the thickness direction of the cam plate to hold the lever at the initial position. This hinders the miniaturization of the connector assembly.
The present invention was developed in view of the above problem and an object thereof is to provide a lever-type connector assembly which can be made smaller in the thickness direction of a cam plate portion.
SUMMARY OF THE INVENTION
The invention relates to a lever-type connector assembly with first and second connectors that are connectable with each other. A lever is rotatably mounted in a housing of the first connector and has at least one cam plate. A cam means is provided at the second connector and is engageable with a mating cam means of the cam plate. The cam means engages the mating cam means while the lever is at an initial position. The lever then is rotated and the two connectors are pulled toward each other for connection by the cam action of the mating cam means and the cam means. The cam plate comprises at least one resilient lock that is engageable with the housing to temporarily hold or lock the lever at the initial position. The resilient lock is deformable at an angle, and preferably substantially a right angle, to the rotation axis of the lever. Accordingly, a space needed for permitting the resilient deformation of the resilient lock is reduced and no space is needed for permitting resilient deformation of the cam plate in the thickness direction, as in the prior art. As a result, the connector assembly can be made smaller.
The cam means preferably comprises a cam pin at the second connector and the mating cam means preferably comprises a cam groove formed in the cam plate for engaging the cam pin.
The resilient lock preferably is resiliently deformable substantially along a plane surface of the cam plate. Accordingly, there is no need to provide space for resilient deformation of the cam plate in the thickness direction, and the connector assembly can be made smaller.
The cam plate preferably is formed with a substantially round bearing hole. A mount groove extends from the bearing hole to an outer edge of the cam plate and is narrower than the inner diameter of the bearing hole. The housing preferably has a supporting shaft with a major outer dimension for closely fitting into the bearing hole and a minor outer dimension sufficiently small for the supporting shaft to pass through the mount groove. Accordingly, the supporting shaft can be fit into the mount groove so that the widthwise direction of the mount groove conforms to the minor dimension of the supporting shaft. The lever is rotated about the supporting shaft and locked after the supporting shaft passes through the mount groove and engages in the bearing hole. In this way, the lever can be mounted easily.
The second connector preferably has at least one unlocking rib disposed for contacting the resilient lock at an initial connection stage, thereby canceling a locked state of the lever with the housing. Accordingly, the lever can be rotated from the initial position, and the two connectors can be connected smoothly with each other.
The second connector preferably has a substantially rectangular receptacle for receiving the first connector, and the unlocking rib also is disposed for preventing an upside-down or improper insertion of the first connector into the receptacle. Accordingly, the construction is simpler than a connector with a separate means for preventing upside down insertion.
The rotation of the lever preferably is guided by rotation guiding means on the housing and/or the lever.
An accommodating recess preferably is defined between an outer wall and an intermediate wall of the housing for accommodating the lever. The cam plate is held between the outer wall and the intermediate wall while defining a small clearance therebetween.
The lever-type connector assembly may further comprise a connection completing resilient locking piece for locking the lever at a connection completing position. The connection completing resilient locking piece may be resiliently deformable in a direction different than the resilient lock, and preferably in a direction of the rotational axis of the lever.
These and other objects, features and advantages of the present invention will become more apparent upon reading of the following detailed description of preferred embodiments and accompanying drawings. It should be understood that even though embodiments are separately described, single features thereof may be combined to additional embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
A lever-type connector assembly according to the invention includes a female connector
10
and a male connector
50
, as shown in
FIG. 1
which are connectable with and separable from each other. The side of each connector
10
,
50
to be connected with a mating side is referred to as a front side in the following description.
The female connector
10
includes a holder
11
that is formed e.g. of a synthetic resin. The holder
11
, as shown in
FIGS. 2
to
5
is substantially in the shape of a wide rectangular frame that is hollow in forward and backward directions. More particularly, the holder
11
has an upper wall
12
, a lower wall
13
and left and right side walls
14
. A ceiling wall
15
is substantially parallel with the upper wall
12
and is between the upper and lower walls
12
and
13
to define a wide slit-like accommodating recess
16
. The inner space of the holder
11
below the accommodating recess
16
is divided into three transversely arranged mount spaces
18
by two partition walls
17
provided between the ceiling wall
15
and the lower wall
13
. The lower wall
13
is formed with resiliently deformable locks
19
corresponding to the respective mount spaces
18
. Further, a wide recess
21
is formed in the lower wall
13
of the holder
11
, and a retainer
22
is fit into the recess
21
from below.
The female connector
10
also includes auxiliary connectors
24
formed e.g. of a synthetic resin and having the shape of a substantially rectangular block (see FIG.
1
). Cavities
25
are formed in the auxiliary connectors
24
, and a female terminal fitting
26
are inserted respectively into the cavities
25
from behind. A wire
27
is secured to each female terminal fitting
26
and is drawn out through the rear end of the auxiliary connector
24
. Each auxiliary connector
24
is inserted into the corresponding mount space
18
of the holder
11
from behind and in the inserting direction. Front and rear ends of the mounted auxiliary connectors
24
are substantially flush with the front and rear end surfaces of the holder
11
. The mounted auxiliary connectors
24
are locked doubly locked by the locks
19
and the retainer
22
fitted in the recess
21
.
A supporting shaft
29
projects up from the ceiling wall
15
in the accommodating recess
16
of the holder
11
. Each of the front and rear surfaces of the supporting shaft
29
has an arcuate cross section, and a diametrical dimension D is defined on the supporting shaft
29
between the front and rear surfaces thereof. Substantially parallel flat surfaces
29
A are formed at the left and right sides of the supporting shaft
29
. A transverse dimension W between the flat portions
29
A of the supporting shaft
29
is smaller than the dimension D between the front and rear surfaces.
A stopper
31
projects on the upper surface of the ceiling wall
15
in the accommodating recess
16
of the holder
11
. Additionally, an escaping groove
32
is formed in the upper wall
12
and the ceiling wall
15
of the holder
11
in front of the supporting shaft
29
. Another escaping groove
33
is formed at a side position of the accommodating recess
16
of the holder
11
. The escaping groove
33
extends backward from the front surface of the holder
11
, and a receiving portion
33
A projects at the rear lower half of the escaping groove
33
.
The female connector
10
further includes a lever
40
, as shown in
FIGS. 5
to
7
. The lever
40
is formed e.g. of a synthetic resin and includes a long narrow substantially flat cam plate
41
. A substantially round bearing hole
42
is formed at a lower surface of the cam plate
41
near one end of the cam plate
41
. The bearing hole
42
of the lever
40
is mounted rotatably about the supporting shaft
29
of the ceiling wall
15
. Thus, the lever
40
is accommodated in the accommodating recess
16
so that the cam plate
41
is held with a small clearance between the upper wall
12
and the ceiling wall
15
.
A mount groove
43
is formed in the lower surface of the cam plate
41
and extends from the bearing hole
42
to the outer edge of the cam plate
41
substantially along the longitudinal direction of the cam plate portion
41
and along a mounting direction MD of the lever
40
to the holder
11
. The mount groove
43
is adapted to guide the supporting shaft
29
to the bearing hole
42
when the lever
40
is mounted into the holder
11
. The width WM of the mount groove
43
is slightly larger than the transverse dimension W between the flat portions
29
A of the supporting shaft
29
. Further, the depth of the mount groove
43
is smaller than the projecting distance of the supporting shaft
29
and is made gradually smaller toward the bearing hole
42
(see
FIG. 6
) to form a step between the bottom surface of the bearing hole
42
and the bottom surface of the mount groove
43
.
A rotation guiding groove
44
is formed in the lower surface of the cam plate
41
and is substantially in the form of a fan with a center at the bearing hole
42
. The stopper
31
on the upper surface of the ceiling wall
15
in the accommodating recess
16
of the holder
11
is engageable with the rotation guiding groove
44
. A rotatable range of the lever
40
is defined by the opposite ends of the rotation guiding groove
44
along which the stopper
31
is displaceable. Thus, the lever
40
is rotatable between an initial position, as shown in
FIG. 10
, and a connection completing position, as shown in FIG.
13
.
A cam groove
45
is formed in the cam plate
41
near the bearing hole
42
and is engageable with a cam pin
54
of the male connector
50
. An opening
45
A of the cam groove
45
is located at the outer edge of the cam plate
41
. The opening
45
A of the cam groove
45
substantially aligns with the escaping groove
32
, when the lever
40
is at the initial position. Thus, the cam groove
45
is ready for receiving the cam pin
54
.
A resilient locking piece
46
is cantilevered from an end of the cam plate
41
at a side substantially opposite the cam groove
45
with respect to the mount groove
43
. The resilient locking piece
46
extends substantially along the plane of the cam plate
41
. The width (vertical dimension) of the resilient locking piece
46
is the same as the thickness of the cam plate
41
, and the leading end of the resilient locking piece
46
is resiliently deformable substantially along the plane of the cam plate
41
. A projection
46
A projects outward at the leading end of the resilient locking piece
46
. The projection
46
A of the resilient locking piece
46
enters the escaping groove
33
when the lever
40
is at the initial position, and the lower half of the projection
46
A engages the receiving portion
33
A for locking. Thus rotation of the lever
40
toward the connection completing position is prevented.
The lever
40
also has an operable portion
47
at an end of the cam plate
41
substantially opposite from the bearing hole
42
. The operable portion
47
is near the rear surface side of the holder
11
at the connection completing position. The operable portion
47
has a substantially rectangular frame
47
A that bulges out from the cam plate
41
in the thickness direction of the cam plate
41
and a finger placing portion
47
B that bulges out from the rectangular frame
47
A in a direction away from the bearing hole
42
. Further, a planar resilient lock
48
is cantilevered substantially in the plane of the cam plate
41
from the end of the lever
40
that has the operable portion
47
and is configured for locking the lever
40
at the connection completing position. The resilient lock
48
extends back when the lever
40
is at the connection completing position, and is resiliently deformable substantially in its thickness direction TD, which is the direction of the rotational axis of the lever
40
. A locking projection
48
A is provided on the upper surface of the resilient lock
48
. The locking projection
48
A is engageable with a claw
34
on the upper wall
12
of the holder
11
when the lever
40
is substantially at the connection completing position. Further, a finger pressing portion
48
B in the form of a substantially flat plate is provided at the leading end of the resilient lock
48
for disengaging the locking projection
48
A from the claw
34
. The finger pressing portion
48
B is inside the substantially rectangular frame
47
A, and a notch
47
C is formed in the upper surface of the substantially rectangular frame
47
A to expose the finger pressing portion
48
B.
The male connector
50
has a housing
51
formed e.g. of a synthetic resin and male terminal fittings
52
are mounted in the housing
51
, as shown in
FIGS. 1
,
8
and
10
. A substantially rectangular receptacle
53
opens at the front side of the housing
51
, and the holder
11
of the female connector
10
is insertable into the receptacle
53
. The male terminal fittings
52
project into the receptacle
53
from the rear end thereof. Thus, the male and female terminal fittings
52
and
26
connect with each other when the connectors
10
,
50
are connected properly.
A cylindrical cam pin
54
and an unlocking rib
55
project down from an upper plate
53
A of the receptacle
53
towards the inner space of the receptacle
53
. The unlocking rib
55
extends from the front end of the receptacle
53
along forward and backward directions and enters the upper half of the escaping groove
33
when the male connector
50
is connected with the female connector
10
.
The connector assembly is assembled by first placing the cam plate
41
of the lever
40
substantially parallel to the upper wall
12
of the holder
11
, as shown in FIG.
5
. The cam plate
41
then is inserted into the accommodating recess
16
of the holder
11
so that the width direction of the mount groove
43
conforms to the width W of the supporting shaft
29
, thereby guiding the supporting shaft
29
into the mount groove
43
. The upper wall
12
and the ceiling wall
15
near the supporting shaft
29
deform slightly away from each other when the supporting shaft
29
is pushed into the mount groove
43
to permit passage of the supporting shaft
29
. The depth of the mount groove
43
becomes gradually smaller toward the bearing hole
42
(see FIG.
6
). Thus, the supporting shaft
29
easily can be pushed deeper into the mount groove
43
. The upper wall
12
and the ceiling wall
15
are restored resiliently to their original shapes, as the supporting shaft
29
reaches the bearing hole
42
, thereby engaging the supporting shaft
29
with the bearing hole
42
(see FIG.
9
).
Assembly proceeds by rotating the lever
40
counterclockwise from the state shown in FIG.
9
. Thus, the stopper
31
is pushed under the cam plate
41
, and the upper wall
12
and the ceiling wall
15
near the stopper
31
deform slightly away from each other. The lever
40
then is rotated to the initial position shown in
FIG. 10
so that the stopper
31
is fit into the rotation guiding groove
44
. As a result, the upper wall
12
and the ceiling wall
15
are restored resiliently to their original shapes. Accordingly, the projection
46
A of the resilient lock
46
enters the escaping groove
33
and engages the receiving portion
33
A to prevent rotation of the lever
40
toward the connection completing position. The orientation of the supporting shaft
29
in the bearing hole
42
deviates from the orientation of the mount groove
43
when the lever
40
is rotated in the state shown in FIG.
9
. Thus, the lever
40
is locked so as not to come out. In this way, the mounting operation of the lever
40
into the holder
11
is completed.
Each auxiliary connector
24
then is fit into the corresponding mount space
18
of the holder
11
, as shown in
FIG. 1
, and the retainer
22
is brought into engagement with the auxiliary connectors
24
to lock the auxiliary connectors
24
so as not to come out.
The holder
11
of the female connector
10
then is inserted lightly into the receptacle
53
of the male connector
50
. Thus, the cam pin
54
fits into the opening
45
A of the cam groove
45
, as shown in
FIG. 11
, and the unlocking rib
55
contacts the projection
46
A of the resilient lock
46
. As a result, the resilient lock
46
deforms and disengages from the receiving portion
33
A so that the lever
40
can rotate. An attempt could be made to insert the female connector
10
into the receptacle
53
upside down. However, such insertion will bring the leading end of the unlocking rib
55
into contact with the holder
11
, thereby preventing further insertion.
The lever
40
then is rotated toward the connection completing position by pushing the operable portion
47
. As a result, the cam action between the cam groove
45
and the cam pin
54
pulls the connectors
10
,
50
toward each other so that the holder
11
is fit further into the receptacle
53
. A force resulting from connecting resistance acts upon the lever
40
during the connecting operation. However, the cam plate
41
is held substantially from the opposite sides along the thickness direction TD in the accommodating recess
16
. Consequently, the cam plate
41
will not deform substantially in the direction of the rotational axis and will not disengage from the supporting shaft
29
.
The locking projection
48
A of the resilient locking piece
48
contacts the claw
34
of the holder
11
when the lever
40
comes closer to the connection completing position. Thus, the resilient locking piece
48
is deformed resiliently in a direction substantially normal to the plane of the cam plate
41
. The resilient locking piece
48
is restored resiliently towards its original shape when the lever
40
reaches the connection completing position and the locking projection
48
A and the claw
34
engage to lock the lever
40
as shown in FIG.
12
. As a result, the two connectors
10
,
50
are connected properly (see FIGS.
13
and
14
).
The two connectors
10
,
50
can be separated by placing a forefinger F
1
on the finger placing portion
47
B of the operable portion
47
and pushing down on the finger pressing portion
48
B of the resilient lock
48
with the tip of the thumb F
2
of the same hand, as shown in FIG.
13
. Thus, the lever
40
is unlocked and the operable portion
47
is pulled to rotate the lever
40
clockwise in FIG.
13
. As a result, the cam pin
54
is displaced along the cam groove
45
toward the opening portion
45
A, and the two connectors
10
,
50
move apart. The cam pin
54
comes out of the cam groove
45
when the lever
40
reaches the initial position, and the two connectors
10
,
50
are separated from each other.
As described above, the resilient lock
46
for locking the lever
40
at the initial position is deformed along the planar surface of the cam plate
41
. Thus, there is no need to provide space for permitting the deformation of the cam plate
41
along the thickness direction, and the connector assembly can be made smaller.
The supporting shaft
29
is fit into the mount groove
43
so that the width direction of the mount groove
43
substantially conforms to the shorter dimension W of the supporting shaft
29
. The supporting shaft
29
passes easily through the mount groove
43
and engages the bearing hole
42
. The lever
40
is locked merely by rotation about the supporting shaft
29
. In this way, the lever
40
can be mounted easily.
The unlocking rib
55
contacts the resilient lock
46
at an initial connection stage to unlock the lever
40
. As a result, the lever
40
can be rotated from the initial position. Therefore, the two connectors
10
,
50
can be connected smoothly.
The unlocking rib
55
also serves as the rib for preventing the upside-down insertion of the female connector
10
into the receptacle
53
. Therefore, the construction can be simplified.
The invention is not limited to the above described and illustrated embodiment. For example, the following embodiments are also embraced by the technical scope of the present invention as defined in the claims. Beside the following embodiments, various changes can be made without departing from the scope and spirit of the present invention as defined in the claims.
In the foregoing embodiment, the lever is mounted in the holder of the split-type connector. However, the lever may also be mounted in housings of connectors other than the split-type connector.
The lever extends along a wall at one side of the holder in the foregoing embodiment. However, the lever also may be U-shaped and located outside the left and right sides of the housing according to the invention.
In the foregoing embodiment, the lever is locked at the initial stage by the resilient lock and is unlocked by the unlocking rib of the male connector. However, the resilient lock may take a semi-locking construction without providing an unlocking means in the mating connector, so that the locked state is canceled by pushing the lever from the initial position to the connection completing position.
