Abstract
Abstract A connector having an engagement detecting device, comprises: a first connector housing for housing a plurality of first connector terminals; a second connector housing for housing a plurality of second connector terminals mated with the first connector terminals, and engaged with the first connector housing; a slider inserted into the first connector housing in two stages of a half engagement position and a full engagement position; and a short-circuit spring disposed within the first connector housing, for shorting electrically two adjacent mated connector terminals 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 is engaged with the first connector housing and thereafter the slider is further inserted into the first connector housing to the full engagement position. The short-circuit spring 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
183 words
An electrical connector having an engagement detecting device, comprising: a first connector housing for housing a plurality of first connector terminals, wherein said first connector housing has a front opening and a rear opening; a second connector housing for housing a plurality of second connector terminals mated with the first connector terminals, and engaged with said first connector housing; a slider being inserted into said front opening and being positioned inside of said first connector housing in two stages of a half engagement position and a full engagement position; and a U-shaped short-circuit spring being inserted into said rear opening and being positioned inside of said first connector housing, for electrically shorting two corresponding connector terminals of said plurality of first connector terminals and second connector terminals when said slider is inserted into said first connector housing to the half engagement position, but electrically disconnecting said corresponding connector terminals when said second connector housing is engaged with said first connector housing 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
183 words
An electrical connector having an engagement detecting device, comprising: a first connector housing for housing a plurality of first connector terminals, wherein said first connector housing has a front opening and a rear opening; a second connector housing for housing a plurality of second connector terminals mated with the first connector terminals, and engaged with said first connector housing; a slider being inserted into said front opening and being positioned inside of said first connector housing in two stages of a half engagement position and a full engagement position; and a U-shaped short-circuit spring being inserted into said rear opening and being positioned inside of said first connector housing, for electrically shorting two corresponding connector terminals of said plurality of first connector terminals and second connector terminals when said slider is inserted into said first connector housing to the half engagement position, but electrically disconnecting said corresponding connector terminals when said second connector housing is engaged with said first connector housing 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
263 words
An electrical connector having an engagement detecting device, comprising: a first connector housing for housing a plurality of first connector terminals, wherein said connector housing has a front opening and a rear opening; a second connector housing for housing a plurality of second connector terminals mated with the first connector terminals, and engaged with said first connector housing; a slider being inserted into said front opening and being positioned inside of said first connector housing in two stages of a half engagement position and a full engagement position; and a short-circuit spring being inserted into said rear opening and being positioned inside of said first connector housing, for electrically shorting two corresponding connector terminals of said plurality of the first connector terminals and second connector terminals when said slider is inserted into said first connector housing to the half engagement position, but electrically disconnecting said corresponding connector terminals when said second connector housing is engaged with said first connector housing and thereafter said slider is further inserted into said first connector housing from the half engagement position to the full engagement position, wherein said short-circuit spring is formed into a U-shape having a pair of elastic arms, each of the elastic arms being formed with a V-shaped contact piece at each free end thereof so as to be connected to or disconnected from the mated connector terminals and 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
263 words
An electrical connector having an engagement detecting device, comprising: a first connector housing for housing a plurality of first connector terminals, wherein said connector housing has a front opening and a rear opening; a second connector housing for housing a plurality of second connector terminals mated with the first connector terminals, and engaged with said first connector housing; a slider being inserted into said front opening and being positioned inside of said first connector housing in two stages of a half engagement position and a full engagement position; and a short-circuit spring being inserted into said rear opening and being positioned inside of said first connector housing, for electrically shorting two corresponding connector terminals of said plurality of the first connector terminals and second connector terminals when said slider is inserted into said first connector housing to the half engagement position, but electrically disconnecting said corresponding connector terminals when said second connector housing is engaged with said first connector housing and thereafter said slider is further inserted into said first connector housing from the half engagement position to the full engagement position, wherein said short-circuit spring is formed into a U-shape having a pair of elastic arms, each of the elastic arms being formed with a V-shaped contact piece at each free end thereof so as to be connected to or disconnected from the mated connector terminals and 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 5
Dependent Claim
60 words
The electrical connector having an engagement detecting device of claim 2, wherein said slider comprises at least one bendable arm which can be stopped by said first connector housing in the half engagement position, a pair of disconnect arms for electrically disconnecting the V-shaped contact pieces of said short-circuit spring from the mated connector terminals, and a full engage portion.
Claim 6
Dependent Claim
67 words
The electrical connector having an engagement detecting device of claim 3, wherein each of the disconnect arms is formed with a sloped surface at a free end thereof to apply the reaction force effectively from the V-shaped contact piece of said short-circuit spring to said slider, 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
46 words
The electrical connector having an engagement detecting device of claim 3, wherein said first connector housing is formed with a movable locking and stopping arm and at least one slider stopper to stop said slider inserted into said first connector housing to the half engagement position.
Claim 8
Dependent Claim
