Abstract
Abstract An upper face of a female connector housing 10 has arc-shaped ribs 15 to support contact members 25 of a pivotable lever 20. If the operating force applied to the lever 20 is large the tendency for the lever 20 to bend towards the connector housing 10 is resisted. Engagement of cam tracks 24 with protrusions of a corresponding connector housing is thereby assured.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
109 words
A lever-type connector comprising a housing having a `U` shaped lever pivoted thereto for movement through an arc between an open position and a closed position, the lever having opposite arms, one end of each arm being pivoted to a respective side of the housing about a common pivot axis, and the other end of each arm being connected to an operating member which spans the housing, wherein one of said operating member and said housing is provided with a bending preventing member adapted to prevent bending of said operating member towards said housing at least along a mid portion of the arc between said open and closed positions.
Claim 2
Dependent Claim
109 words
A lever-type connector comprising a housing having a `U` shaped lever pivoted thereto for movement through an arc between an open position and a closed position, the lever having opposite arms, one end of each arm being pivoted to a respective side of the housing about a common pivot axis, and the other end of each arm being connected to an operating member which spans the housing, wherein one of said operating member and said housing is provided with a bending preventing member adapted to prevent bending of said operating member towards said housing at least along a mid portion of the arc between said open and closed positions.
Claim 3
Dependent Claim
38 words
A connector according to claim 1 wherein the bending preventing member has a contact face for contact with the other of said housing and operating member, said contact face being at a constant radius from said pivot axis.
Claim 4
Dependent Claim
20 words
A connector according to claim 1 wherein the bending preventing member is in a mid region of said operating member.
Claim 5
Dependent Claim
45 words
A connector according to claim 1 wherein the other of said operating member and housing is provided with a movement preventing member adapted for abutment with said bending preventing member and for preventing movement of said operating member in the direction of said pyot axis.
Claim 6
Dependent Claim
42 words
A connector according to claim 4 wherein the bending preventing member is an upstanding rib of said housing, and the movement preventing member comprises two depending ribs of said operating member, one depending rib being on either side of said upstanding rib.
Claim 7
Dependent Claim
40 words
A connector according to claim 1 and further including a latch at the middle of said operating member for retaining the lever against movement relative to the housing, a bending preventing member being provided on either side of said latch.
Claim 8
Dependent Claim
28 words
A connector according to claim 1 wherein the bending preventing member is spaced from said operating member by a small clearance when said operating member is at rest.
Claim 9
Dependent Claim
22 words
A connector according to claim 7 wherein the bending preventing member is effective throughout movement of the operating member through said arc.
Claim 10
Dependent Claim
18 words
A connector according to claim 1 wherein the bending preventing member makes light contact with said operating member.
Claim 11
Dependent Claim
22 words
A connector according to claim 9 wherein the bending preventing member is effective throughout movement of the operating member through said arc.
Claim 12
Dependent Claim
22 words
A connector according to claim 1 wherein the bending preventing member is effective throughout movement of the operating member through said arc.
Claim 13
Dependent Claim
45 words
A connector according to claim 11 wherein the other of said operating member and housing is provided with a movement preventing member adapted for abutment with said bending preventing member and for preventing movement of said operating member in the direction of said pivot axis.
Claim 14
Dependent Claim
20 words
A connector according to claim 1 wherein the bending preventing member comprises one or more upstanding ribs of said housing.
Claim 15
Dependent Claim
45 words
A connector according to claim 13 wherein the other of said operating member and housing is provided with a movement preventing member adapted for abutment with said bending preventing member and for preventing movement of said operating member in the direction of said pivot axis.
