Abstract
Abstract To reduce the size of a lever connector and simplify the construction of a mold therefor. A lever 30 is mounted on a female connector housing 20 such that a part of the lever 30 is accommodated in a receptacle 11 of a male connector housing 10 together with a female connector housing 20 in a connected state of the male and female connector housings 10, 20. Thus, a movement of the lever in its opening direction is restricted by an outer wall of the receptacle 11, eliminating the need to provide a protection wall for preventing the disengagement of the lever 30 in the connected state. This results in a reduced size of the lever connector. Further, the lever 30 is formed in its outer surfaces with cam grooves 33 in the form of recesses. Thus, a mold for the lever 30 can be pulled outward, enabling the simplification of the construction thereof.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
159 words
A lever connector, comprising: first and second connector housings (10, 20) connectable with each other, a lever (30) having at least one cam groove (33) which is provided at or on
the second connector housing (20), and at least one engaging pin (15) which is provided at or on the first
connector housing (10) and engageable with the cam groove (33), the first and
second connector housings (10, 20) being connectable by the cam effect of the
at least one engaging pin (15) and the at least one cam groove (33) during the
displacement of the lever (30), wherein: the at least one engaging pin (15) is so formed as to project from a wall
surface of a receptacle (11) of the first connector housing (10) for
accommodating the second connector housing (20) and at least a part of the
lever (30) is accommodated in the receptacle (11) as the first and second
connector housings (10, 20) are connected.
Claim 2
Dependent Claim
29 words
A lever connector according to claim 1, wherein the lever (30) is
pivotably supported, preferably by a mount pin (25) provided at or on the second
connector housing (20).
Claim 3
Dependent Claim
30 words
A lever connector according to claim 2, wherein the cam groove (33)
has such a configuration, that its distance to the pivot center (25) is variable in an
azimuthal direction.
Claim 4
Dependent Claim
45 words
A lever connector according to one or more of the preceding claims,
wherein the lever (30) is mounted outside the second connector housing (20)
and/or the cam groove (33) is a recess formed in a surface, preferably in an outer
surface of the lever (30).
Claim 5
Dependent Claim
47 words
A lever connector according to one or more of the preceding claims,
wherein holding means (24; 32; 34; 52) are provided at the first connector
housing (10), the second connector housing (20) and/or the lever (30) for holding
the lever (30) in a predetermined or predeterminable position.
Claim 6
Dependent Claim
40 words
A lever connector according to one or more of the preceding claims,
wherein the first and second connector housings (10, 20) comprise tilt prevention
means (13; 22), which prevent a tilting of the connector housing (10, 20) during
their connection.
Claim 7
Dependent Claim
43 words
A lever connector according to one or more of the preceding claims
further comprising: a retainer (40) which is provided on one outer side surface of the first
and/or second connector housing (10; 20), preferably including the longer sides of
the engaging surface.
Claim 8
Dependent Claim
33 words
A lever connector according to claim 7, wherein the retainer (40) is
held in a position where it slightly projects from said outer side surface, in
particular in a partly locked position thereof.
Claim 9
Dependent Claim
34 words
A lever connector according to claim 7 or 8, wherein the retainer (40)
is formed with a recess portion (41) for avoiding the interference with the lever
(30) in the partly locked position thereof.
Claim 10
Dependent Claim
46 words
A lever connector according to one or more of the preceding claims
7 to 9, wherein the lever (30) is so mounted as to hold a side surface of the
second connector housing (20), where the retainer (40) is mounted, and a side
surface opposite thereto.
