Abstract
Abstract A connector assembly comprises a first connector housing with a flexible locking arm, and a second connector housing having an engaging section which is provided for the flexible locking arm. In the first connector housing, a shorting contactor including an elastic contact plate is set in a displacement permitting space provided for the flexible locking arm in such a manner that the elastic contact plate is displaced in association with the displacement of the flexible locking arm. In the second connector housing, a pair of engagement detecting metal terminals are provided in confrontation with the shorting contactor. When the first and second connector housings are incompletely engaged with each other, the shorting contactor is not contact with the engagement detecting metal terminals by the displacement of elastic contact plate which is due to the displacement of the flexible locking arm.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
172 words
A connector engagement detecting device comprising: a first connector housing having a flexible locking arm; a shorting contactor set in a displacement permitting space provided for said flexible locking arm in said first connector housing, said shorting contactor including an elastic contact plate having a front and rear end, which is displaced in association with displacement of said flexible locking arm; a second connector housing having an engaging section provided for said flexible locking arm; and a pair of engagement detecting metal terminals provided in said second connector housing in confrontation with the front end of said elastic contact plate of said shorting contactor, wherein when said first and second connector housings are incompletely engaged with each other, said shorting contactor is prevented from being in contact with said engagement detecting metal terminals by displacement of said front end of said elastic contact plate of said shorting contactor in an upward direction within the displacement permitting space, which is due to the displacement of said flexible locking arm in a downward direction.
Claim 2
Dependent Claim
172 words
A connector engagement detecting device comprising: a first connector housing having a flexible locking arm; a shorting contactor set in a displacement permitting space provided for said flexible locking arm in said first connector housing, said shorting contactor including an elastic contact plate having a front and rear end, which is displaced in association with displacement of said flexible locking arm; a second connector housing having an engaging section provided for said flexible locking arm; and a pair of engagement detecting metal terminals provided in said second connector housing in confrontation with the front end of said elastic contact plate of said shorting contactor, wherein when said first and second connector housings are incompletely engaged with each other, said shorting contactor is prevented from being in contact with said engagement detecting metal terminals by displacement of said front end of said elastic contact plate of said shorting contactor in an upward direction within the displacement permitting space, which is due to the displacement of said flexible locking arm in a downward direction.
Claim 3
Dependent Claim
87 words
The connector engagement detecting device as claimed in claim 1, wherein said shorting contractor includes a base plate, and said elastic contact plate is provided over said base plate through a bent portion in such a manner that the front end of said elastic contact plate is extended beyond said bent portion, wherein the front end of said elastic contact plate has shorting contacts formed thereon and said elastic contact plate has a pair of mounting ears at a base end thereof, extending toward said base plate.
Claim 4
Dependent Claim
86 words
The connector engagement detecting device as claimed in claim 2, wherein said shorting contacts on said elastic contact plate are provided in such a manner that said shorting contacts are able to go in and out of an accommodating chamber formed in said first connector housing in such a manner that said chamber is opened in a front end face of said first connector housing, said shorting contacts being brought into contact with said engagement detecting metal terminals when caused to go into said accommodating chamber.
Claim 5
Dependent Claim
98 words
The connector engagement detecting device as claimed in claim 1, wherein said shorting contactor has a Z-shape and includes a base plate, an elastic plate which is provided over said base plate through a first bent portion, and said elastic contact plate which is provided over said elastic plate through a second bent portion in such a manner that said elastic contact plate is extended beyond said first bent portion, said elastic contact plate having shorting contacts wherein said shorting contacts are displaced in an upward direction when said second bent portion is displaced in a downward direction.
Claim 6
Dependent Claim
20 words
The connector engagement detecting device as claimed in claim 4, wherein said second bent portion includes a raised driven portion.
Claim 7
Dependent Claim
39 words
The connector engagement detecting device as claimed in claim 4, wherein said pair of engagement detecting metal terminals of said second connector housing enter the displacement permitting space provided for said flexible locking arm in said first connector housing.
Claim 8
Dependent Claim
99 words
The connector engagement detecting device as claimed in claim 1, wherein said shorting contactor includes a base plate, said elastic contact plate being provided under said base plate through a bent portion, said base plate being locked to an upper inner surface of said flexible locking arm, and the front end of said elastic contact plate has shorting contacts formed thereon, said base plate being abutted against a fulcrum member formed on a bottom surface of a recess of the displacement permitting space in said first connector housing, so that said shorting contactor is swung about said fulcrum member.
Claim 9
Dependent Claim
42 words
The connector engagement detecting device as claimed in claim 7, wherein said base plate of said shorting contactor has protective stoppers on both sides near said bent portion in such a manner that said protective stoppers extend below said elastic contact plate.
Claim 10
Dependent Claim
44 words
The connector engagement detecting device as claimed in claim 7, wherein said base plate of said shorting contactor has protective receiving plates on both sides near said bent portion in such a manner that said protective receiving plates are spaced from said bent portion.
Claim 11
Dependent Claim
