Abstract
Abstract A connector includesvone connector housing having a flexible lock arm, other connector housing having an engagement portion corresponding to the flexible lock arm, a short-circuiting contact member having resilient contact pieces, the short-circuiting contact member arranged on a displacement allowing space side of the flexible lock arm in the one connector housing, the resilient contact pieces being displaced in accordance with displacement of the flexible lock arm; and a pair of connection sensing pin-type terminal fittings arranged so as to confront the short-circuiting contact member in the other connector housing, wherein when the pair of connector housings are connected incompletely, the flexible lock arm is displaced to displace the resilient contact pieces so as to break contact of the resilient contact pieces with the connection sensing pin-type terminal fittings.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
An electrical connector comprising: a first connector housing having a flexible lock arm extending therefrom; a second connector housing having am engagement portion corresponding to the flexible lock arm; a short-circuiting contact member having resilient contact pieces, the short-circuiting contact member being arranged on a displacement allowing space side of the flexible lock arm in the first connector housing, the resilient contact pieces being displaced in response to displacement of the flexible lock arm; and a pair of connection sensing pin-type terminal fittings arranged in the second connector housing so as to contact said resilient contact pieces when the first and second connector housings are completely engages with each other, wherein when said first and second connector housings are connected incompletely, the flexible lock arm is displaced to push the resilient contact pieces away from the connection sensing pin-type terminal fittings to eliminate contact therebetween and wherein said pin-type terminals are disposed substantially between said lock arm and said resilient contact pieces when the first and second housings are completely engaged with each other.
Claim 2
Dependent Claim
174 words
An electrical connector comprising: a first connector housing having a flexible lock arm extending therefrom; a second connector housing having am engagement portion corresponding to the flexible lock arm; a short-circuiting contact member having resilient contact pieces, the short-circuiting contact member being arranged on a displacement allowing space side of the flexible lock arm in the first connector housing, the resilient contact pieces being displaced in response to displacement of the flexible lock arm; and a pair of connection sensing pin-type terminal fittings arranged in the second connector housing so as to contact said resilient contact pieces when the first and second connector housings are completely engages with each other, wherein when said first and second connector housings are connected incompletely, the flexible lock arm is displaced to push the resilient contact pieces away from the connection sensing pin-type terminal fittings to eliminate contact therebetween and wherein said pin-type terminals are disposed substantially between said lock arm and said resilient contact pieces when the first and second housings are completely engaged with each other.
Claim 3
Dependent Claim
47 words
An electrical connector according to claim 1, wherein said short-circuiting contact member includes a pair of the resilient contact pieces corresponding to the pair of connection sensing pin-type terminal fittings, and the pair of resilient contact pieces are juxtaposed through a slit in the short-circuiting contact member.
Claim 4
Dependent Claim
53 words
An electrical connector according to claim 2, wherein a pair of driven portions confronting the flexible lock arm are respectively arranged on the pair of resilient contact pieces, and collision plate portions are arranged on a slit side of the pair of driven portion so as to minimize deflection of said driven portions.
Claim 5
Dependent Claim
31 words
An electrical connector according to claim 2, wherein the pair of driven portions arranged on the pair of resilient contact pieces are confronted with press portions of the flexible lock arm.
Claim 6
Dependent Claim
87 words
An electrical connector according to claim 2, wherein short-circuiting contact points of the resilient contact pieces confront a intermediate wall surface of the first connector housing therein in such a manner that a gap is defined between the short-circuiting contact points of the resilient contact pieces and the intermediate wall surface of the first connector housing so as to allow the connection sensing pin-type terminal fittings to enter thereinto, and the intermediate wall surface is located on said displacement allowing space side of the flexible lock arm.
