Abstract
Abstract The quick lock/quick release connector is fixed within a socket in a neck of a pacer and includes gripping members for gripping a terminal pin at the distal end of a terminal electrode assembly inserted in the socket and for establishing good mechanical and electrical connection with the terminal pin. The connector further includes a mechanism for manipulating the gripping members from the outside of the pacer body to release the grip of the gripping members on the terminal pin.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
110 words
A terminal pin connector assembly for a pacer having a socket for receiving a terminal electrode assembly with a terminal pin having an annular groove therein, said connector assembly comprising a terminal pin with an annular grooves therein, quick lock/quick release connector means positioned in the socket and having means for resiliently and snap fittingly engaging in the groove in said terminal pin received in the socket for making a good mechanical and electrical connection with said terminal pin and means manually manipulatable without the aid of a tool from the outside of the pacer for actuating the engaging means to release the mechanical grip thereof on said terminal pin.
Claim 2
Dependent Claim
110 words
A terminal pin connector assembly for a pacer having a socket for receiving a terminal electrode assembly with a terminal pin having an annular groove therein, said connector assembly comprising a terminal pin with an annular grooves therein, quick lock/quick release connector means positioned in the socket and having means for resiliently and snap fittingly engaging in the groove in said terminal pin received in the socket for making a good mechanical and electrical connection with said terminal pin and means manually manipulatable without the aid of a tool from the outside of the pacer for actuating the engaging means to release the mechanical grip thereof on said terminal pin.
Claim 3
Dependent Claim
50 words
The connector assembly of claim 1 wherein said engaging means includes means for producing a telltale audible click when said engaging means engages in the annular groove in said terminal pin to indicate to the user of the connector assembly that the terminal pin has been electrically and mechanically engaged.
Claim 4
Dependent Claim
32 words
The connector assembly of claim 1 wherein said engaging means comprise a ring shaped electrical and mechanical coupling member having a plurality of flexible fingers extending axially therefrom within the pacer socket.
Claim 5
Dependent Claim
21 words
The connector assembly of claim 3 wherein said plurality of flexible fingers comprises at least three and preferably four flexible fingers.
Claim 6
Dependent Claim
22 words
The connector assembly of claim 3 wherein said flexible fingers are spaced equidistantly around the ring shaped electrical and mechanical coupling member.
Claim 7
Dependent Claim
44 words
The connector assembly of claim 3 wherein each one of said flexible fingers has a claw on the free end thereof configured to be received within the annular groove in said terminal pin in a snap lock manner to positively engage the terminal pin.
Claim 8
Dependent Claim
40 words
The connector assembly of claim 6 wherein each claw has a shoulder extending generally radially inwardly toward the axis of the ring shaped electrical and mechanical coupling member for engaging an edge of the annular groove in the terminal pin.
Claim 9
Dependent Claim
14 words
The connector assembly of claim 3 wherein said fingers define a generally cylindrical envelope.
Claim 10
Dependent Claim
18 words
The connector assembly of claim 8 wherein a plunger is received within said cylindrical envelope within said fingers.
Claim 11
Dependent Claim
71 words
The connector assembly of claim 9 wherein each of said fingers has a claw at the free end thereof and an inwardly facing cam surface adjacent said claw, and said plunger is slidable within the cylindrical envelope for engaging said cam surfaces of said fingers to cause said fingers to flex radially outwardly to release engagement of said electrical and mechanical coupling member in the annular groove of said terminal pin.
Claim 12
Dependent Claim
19 words
The connector assembly of claim 10 wherein said plunger has a pin which extends axially rearwardly from said plunger.
Claim 13
Dependent Claim
45 words
The connector assembly of claim 11 wherein a free end of said pin extends through said ring shaped electrical and mechanical coupling member, through a bore in the pacer, and terminates at a location exterior of the pacer, said pin defining said manually manipulatable means.
Claim 14
Dependent Claim
30 words
The connector assembly of claim 12 wherein said manually manipulatable means further includes a flexible sealing disc hermetically sealed to the outer surface of the pacer about the bore therein.
Claim 15
Dependent Claim
17 words
The connector assembly of claim 13 wherein said flexible sealing disc is made of silicone elastomer material.
Claim 16
Dependent Claim
42 words
The connector assembly of claim 13 wherein said free end of said pin engages said sealing disc whereby depression of said disc forces said plunger against said fingers to cause said claws to disengage from the annular groove of the terminal pin.
Claim 17
Dependent Claim
57 words
The connector assembly of claim 12 wherein said plunger has a button at the forward end thereof which is adapted to abut against the terminal pin and which is adapted to act upon and urge the terminal pin out of its engagement within said connector means when said pin is pushed into the bore in the pacer.
Claim 18
Dependent Claim
32 words
The connector assembly of claim 13 wherein said fingers are resilient such that said cam surfaces will push said plunger to its rearward position once pressure is released on said sealing disc.
