Abstract
Abstract A connector having an engagement detecting device, comprises: a first connector housing (100) for housing a plurality of first connector terminals (23); a second connector housing (200) for housing a plurality of second connector terminals (21) mated with the first connector terminals, and engaged with the first connector housing; a slider (300, 300A) inserted into the first connector housing in two stages of a half engagement position and a full engagement position; and a short-circuit spring (400) disposed within the first connector housing, for shorting electrically two adjacent mated connector terminals (23, 21) when the slider is inserted into the first connector housing to the half engagement position, but disconnecting electrically the same two adjacent mated connector terminals when the second connector housing (200) is engaged with the first connector housing (100) and thereafter the slider is further inserted into the first connector housing to the full engagement position. The short-circuit spring (400) can apply a reaction force to the slider when the slider is further inserted to the full engagement position, thus providing a stable connector engagement detecting device while decreasing the number of parts.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
154 words
A connector having an engagement detecting device, comprising: a first connector housing (100) for housing a plurality of first connector terminals (23); a second connector housing (200) for housing a plurality of second connector terminals (21) mated with the first connector terminals, and engaged with said first connector housing; a slider (300, 300A) inserted into said first connector housing in two stages of a half engagement position and a full engagement position; and a short-circuit spring (400) disposed within said first connector housing, for shorting electrically two adjacent mated connector terminals (23, 21) when said slider is inserted into said first connector housing to the half engagement position, but disconnecting electrically the same two adjacent mated connector terminals when said second connector housing (200) is engaged with said first connector housing (100) and thereafter said slider is further inserted into said first connector housing from the half engagement position to the full engagement position.
Claim 2
Dependent Claim
154 words
A connector having an engagement detecting device, comprising: a first connector housing (100) for housing a plurality of first connector terminals (23); a second connector housing (200) for housing a plurality of second connector terminals (21) mated with the first connector terminals, and engaged with said first connector housing; a slider (300, 300A) inserted into said first connector housing in two stages of a half engagement position and a full engagement position; and a short-circuit spring (400) disposed within said first connector housing, for shorting electrically two adjacent mated connector terminals (23, 21) when said slider is inserted into said first connector housing to the half engagement position, but disconnecting electrically the same two adjacent mated connector terminals when said second connector housing (200) is engaged with said first connector housing (100) and thereafter said slider is further inserted into said first connector housing from the half engagement position to the full engagement position.
Claim 3
Dependent Claim
101 words
The connector having an engagement detecting device of claim 1, wherein said short-circuit spring (400) is formed into a U-shape having a pair of elastic arms (404), each of the elastic arms (404) being formed with a V-shaped contact piece (410, 412) at each free end thereof in such a way as to be connected to or disconnected from the mated connector terminals and further as to apply a reaction force from the V-shaped contact piece to said slider when said slider is being further inserted into said first connector housing from the half engagement position to the full engagement position.
Claim 4
Dependent Claim
68 words
The connector having an engagement detecting device of claim 2, wherein said slider (300) is formed with at least one bendable arm (340, 320) stopped by said first connector housing in the half engagement position, a pair of disconnect arms (310) for disconnecting electrically the V-shaped contact pieces (410) of said short-circuit spring (400) from the mated connector terminals (23, 21) respectively, and a full engage portion (352).
Claim 5
Dependent Claim
85 words
The connector having an engagement detecting device of claim 2, wherein the slider (300B) is formed with a single disconnect arm (310) inserted into a contact portion between one of the elastic arms (404) of the short-circuit spring (400) and the terminal, when the slider is moved from the half engagement position to the full engagement position to disconnect conduction of the contact portion between the two; and further a guide groove for guiding the disconnect arm is formed on one of said connector housings.
Claim 6
Dependent Claim
71 words
The connector having an engagement detecting device of claim 3, wherein each of the disconnect arms (310) is formed with a sloped surface (312) at a free end thereof to apply the reaction force effectively from the V-shaped contact piece (410) of said short-circuit spring (400) to said slider (300), when said slider is further inserted into said first connector housing from the half engagement position to the full engagement position.
Claim 7
Dependent Claim
47 words
The connector having an engagement detecting device of claim 3, wherein said first connector housing (100) is formed with a movable lock/stop arm (112) and at least one slider stopper (150) to stop said slider inserted into said first connector housing (100) to the half engagement position.
Claim 8
Dependent Claim
76 words
The connector having an engagement detecting device of claim 6, wherein said second connector housing (200) is formed with a slider release portion (210) for moving the movable lock/stop arm (112) and a slider release projection (206) for moving the bendable arm (320) of said slider, to allow said slider to move from the half engagement position to the full engagement position after said second connector housing (200) is engaged with said first connector housing (100).
Claim 9
Dependent Claim
51 words
The connector having an engagement detecting device of claim 3, wherein said fist connector housing (100) is formed with a movable full engage projection (114) engaged with the full engage portion (352) of said slider when said slider is inserted into said first connector housing (100) to the full engagement position.
Claim 10
Dependent Claim
34 words
The connector having an engagement detecting device of claim 3, wherein said first connector housing (100) is formed with a pair of guide grooves (134) for guiding a pair of the disconnect arms (310).
