Abstract
Abstract A connector comprises a housing provided with a recess (7), a terminal cavity (9) and a gap (10), and a contact piece (2) provided with a base portion (2') and bifurcated free ends (3, 3'). Contact terminals (6, 6') of wires (W, W'), project into the recess through the terminal cavity. The base portion of the contact piece is fitted into the gap, the bifurcated free ends of the contact piece project into the recess, and only one of the bifurcated free ends is normally in contact with one of the contact terminals. Therefore, when an arm of the housing of an other connector is fitted into the recess, the other of the bifurcated free ends is brought into contact with the other of the contact terminals and completes an electrical connection between them.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
147 words
A connector for connection to a complementary connector, comprising: a connector housing haing a contact recess, a contact terminal cavity, and a contact piece gap; a contact piece having a base portion and bifurcated free ends, said base portion of said contact piece disposed in said contact piece gap, and said bifurcated free ends of said contact piece extending into said contact recess; and wire contact terminals projecting from said contact terminal cavity into said contact recess of said connector housing; one of said bifurcated free ends of said contact piece arranged so as to contact one of said wire contact terminals in said recess, and another of said bifurcated free ends arranged so as to contact another of said wire contact terminals when an arm of a complementary connector housing is connected to said contact recess to complete an electrical circuit between said wire contact terminals.
Claim 2
Dependent Claim
147 words
A connector for connection to a complementary connector, comprising: a connector housing haing a contact recess, a contact terminal cavity, and a contact piece gap; a contact piece having a base portion and bifurcated free ends, said base portion of said contact piece disposed in said contact piece gap, and said bifurcated free ends of said contact piece extending into said contact recess; and wire contact terminals projecting from said contact terminal cavity into said contact recess of said connector housing; one of said bifurcated free ends of said contact piece arranged so as to contact one of said wire contact terminals in said recess, and another of said bifurcated free ends arranged so as to contact another of said wire contact terminals when an arm of a complementary connector housing is connected to said contact recess to complete an electrical circuit between said wire contact terminals.
Claim 3
Dependent Claim
122 words
The connector as set forth in claim 1, wherein: said bifurcated free ends extend from said base portion of said contact piece; said one of said bifurcated free ends having a downwardly bent portion bent downward relatively sharply from said base portion toward said contact recess and an upwardly bent portion at the forward end of said downwardly bent portion; and said other of said bifurcated free ends, longer than said one of said bifurcated free ends, having a downwardly bent portion bent downward relatively gently from said base portion toward said contact recess, an upwardly bent intermediate portion at the forward end of said downwardly bent portion, and a downwardly bent forward portion at the forward end of said intermediate portion.
Claim 4
Dependent Claim
117 words
The connector as set forth in claim 1, wherein: said bifurcated free ends extend from said base portion of said contact piece; said one of said bifurcated free ends having a downwardly bent portion bent downward relatively sharply from said base portion toward said contact recess and an upwardly bent portion at the forward end of said downwardly bent portion; said other of said bifurcated free ends, longer than said one of said bifurcated free ends, having a downwardly bent portion bent downward relatively sharply from said base portion toward said contact recess, a horizontally extending intermediate portion at the forward end of said downwardly bent portion, and upwardly bent portions extending upwardly from said intermediate portion.
Claim 5
Dependent Claim
136 words
A connector comprising: a first connector housing, said housing provided with a locking portion on the outside thereof, said locking portion having a recess; a second connector housing for connection with said first connector housing in a connecting direction, said second connector housing having an arm for engagement with said recess of said locking portion; a pair of contact terminals in said recess parallel to said connecting direction of said first and second connector housings; a highly resilient contact piece having bifurcated free ends, at least one of said bifurcated free ends disposed adjacent one of said contact terminals with a clearance therebetween such that when said arm of said second connector housing is engaged with said recess, said arm causes said at least one bifurcated free end to engage said one of said contact terminals.
Claim 6
Dependent Claim
136 words
A connector comprising: a first connector housing, said housing provided with a locking portion on the outside thereof, said locking portion having a recess; a second connector housing for connection with said first connector housing in a connecting direction, said second connector housing having an arm for engagement with said recess of said locking portion; a pair of contact terminals in said recess parallel to said connecting direction of said first and second connector housings; a highly resilient contact piece having bifurcated free ends, at least one of said bifurcated free ends disposed adjacent one of said contact terminals with a clearance therebetween such that when said arm of said second connector housing is engaged with said recess, said arm causes said at least one bifurcated free end to engage said one of said contact terminals.
