Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
134 words
A connector comprising: a first connector housing having a fitting recess portion; a seal ring having an elastic seal portion and being attached to said fitting recess portion, said seal portion having a cavity provided in a wall thereof; a second connector housing including a forward half portion adapted to be retained within said fitting recess portion so as to press against an inner circumference of said seal ring; a detection switch disposed within said cavity in said wall of said elastic seal portion, and including a pair of confronting contacts adapted to electrically contact each other when said second connector is coupled to said first connector causing the wall of said elastic seal portion to be compressed thereby indicating that said first and second connector housing have been completely coupled to one another.
Claim 2
Dependent Claim
134 words
A connector comprising: a first connector housing having a fitting recess portion; a seal ring having an elastic seal portion and being attached to said fitting recess portion, said seal portion having a cavity provided in a wall thereof; a second connector housing including a forward half portion adapted to be retained within said fitting recess portion so as to press against an inner circumference of said seal ring; a detection switch disposed within said cavity in said wall of said elastic seal portion, and including a pair of confronting contacts adapted to electrically contact each other when said second connector is coupled to said first connector causing the wall of said elastic seal portion to be compressed thereby indicating that said first and second connector housing have been completely coupled to one another.
Claim 3
Dependent Claim
33 words
A connector as claimed in claim 1, wherein said first connector housing is a male connector housing and said second connector housing is a female connector housing to be coupled with each other.
Claim 4
Dependent Claim
141 words
A connector, comprising: a first connector housing having a forward half portion; a second connector housing including a tubular wall defining a fitting recess portion for coupling said first and second connector housings by fitting said forward half portion of said first connector housing into said fitting recess portion of said second connector housing; and a connector coupled state ensuring means for ensuring that said first and second connector housing are completely coupled to one another, said ensuring means including a detection switch provided in said first connector housing and facing a forward edge of said tubular wall of said second connector housing; and a switch actuating projection provided at the forward edge of said tubular wall of said second connector housing for turning on said detection switch only in a normally coupled state between said first and second connector housings.
Claim 5
Dependent Claim
141 words
A connector, comprising: a first connector housing having a forward half portion; a second connector housing including a tubular wall defining a fitting recess portion for coupling said first and second connector housings by fitting said forward half portion of said first connector housing into said fitting recess portion of said second connector housing; and a connector coupled state ensuring means for ensuring that said first and second connector housing are completely coupled to one another, said ensuring means including a detection switch provided in said first connector housing and facing a forward edge of said tubular wall of said second connector housing; and a switch actuating projection provided at the forward edge of said tubular wall of said second connector housing for turning on said detection switch only in a normally coupled state between said first and second connector housings.
Claim 6
Dependent Claim
33 words
A connector as claimed in claim 3, wherein said first connector housing is a male connector housing and said second connector housing is a female connector housing to be coupled with each other.
