Pacer connector

Claim 2

A pacer connector arrangement for connecting an electrode plug having two pins extending from projections thereon to a pacer circuit comprising a pair of connector assemblies, each for coupling signals between the pacer circuit and a respective plug pin, each of said connector assemblies having a multi-pronged collet embedded in the pacer, each prong thereof having a ridge projecting toward the central axis of the collet with the radial spacings of the ridges being such that when a pin is inserted therebetween the prongs are forced slightly outwardly, a guide ring disposed around the forward end of said multi-pronged collet for guiding a pin inserted therethrough along the axis of said collet, and a gasket disposed forwardly of said guide ring and having an internal configuration for effecting a water-tight seal with a respective one of the pin projections on said plug, both of said collets and their associated guide rings and gaskets being contained at the rear of a receptacle in the pacer into which said plug is insertable, and means for mechanically locking said plug in said receptacle.

Claim 3

A pacer in accordance with claim 1 further including a retainer disposed around each of said multi-pronged collets, the rear of each collet being fixed to the rear of its respective retainer and each of said retainers providing clearance around the retained collet prongs for allowing slight outward movement thereof when a plug pin is inserted therein.

Claim 4

A pacer in accordance with claim 2 wherein the rear end of each retainer and its retained collet is closed.

Claim 5

A pacer in accordance with claim 3 wherein each of said guide rings includes a tapered bore having its smaller diameter end adjacent to the forward end of the respective collet.

Claim 6

A pacer in accordance with claim 4 wherein each of said gaskets includes a plurality of internal ridges for securing a respective one of said plug projections.

Claim 7

A pacer in accordance with claim 2 wherein each of said guide rings includes a tapered bore having its smaller diameter end adjacent to the forward end of the respective collet.

Claim 8

A pacer in accordance with claim 6 wherein each of said collets extends slightly forward of its respective retainer and the respective guide ring bears against the forward end of the retainer and encloses the projecting portions of the prongs extending therefrom.

Claim 9

A pacer connector arrangement for connecting an electrode plug pin to a pacer circuit comprising a connector assembly for coupling signals between the pacer circuit and the plug pin, said connector assembly having a multi-pronged collet embedded in the pacer, each prong thereof having a ridge projecting toward the central axis of the collet with the radial spacings of the ridges being such that when a pin is inserted therebetween the prongs are forced slightly outwardly, means disposed forward of said multi-pronged collet for guiding a pin inserted therethrough along the axis of said collet and for effecting a water-tight seal with said plug, said collet and said forwardly disposed means being contained at the rear of a receptacle in the pacer into which said plug is insertable, means for mechanically locking said plug in said receptacle, a retainer disposed around said multi-pronged collet, the rear of said collet being fixed to the rear of said retainer, said retainer providing clearance around the retained collet prongs for allowing slight outward movement thereof when a plug pin is inserted therein, and wherein the pin extends from a projection of said plug, and said forwardly disposed means includes a plurality of internal ridges for securing said plug projection and effecting a water-tight seal therewith.

Claim 10

A pacer connector arrangement for connecting an electrode plug pin to a pacer circuit comprising a connector assembly for coupling signals between the pacer circuit and the plug pin, said connector assembly having a multi-pronged collet embedded in the pacer, each prong thereof having a ridge projecting toward the central axis of the collet with the radial spacings of the ridges being such that when a pin is inserted therebetween the prongs are forced slightly outwardly, means disposed forward of said multi-pronged collet for guiding a pin inserted therethrough along the axis of said collet and for effecting a water-tight seal with said plug, said collet and said forwardly disposed means being contained at the rear of a receptacle in the pacer into which said plug is insertable, means for mechanically locking said plug in said receptacle, a retainer disposed around said multi-pronged collet, the rear of said collet being fixed to the rear of said retainer, said retainer providing clearance around the retained collet prongs for allowing slight outward movement thereof when a plug pin is inserted therein, and wherein the pin extends from a projection of said plug, and said forwardly disposed means includes a plurality of internal ridges for securing said plug projection and effecting a water-tight seal therewith.

Claim 11

A pacer connector arrangement for connecting an electrode plug pin to a pacer circuit comprising a connector assembly for coupling signals between the pacer circuit and the plug pin, said connector assembly having a multi-pronged collet embedded in the pacer, each prong thereof having a ridge projecting toward the central axis of the collet with the radial spacings of the ridges being such that when a pin is inserted therebetween the prongs are forced slightly outwardly, means disposed forward of said multi-pronged collet for guiding a pin inserted therethrough along the axis of said collet and for effecting a water-tight seal with said plug, said collet and said forwardly disposed means being contained at the rear of a receptacle in the pacer into which said plug is insertable, means for mechanically locking said plug in said receptacle, a retainer disposed around said multi-pronged collet, the rear of said collet being fixed to the rear of said retainer, said retainer providing clearance around the retained collet prongs for allowing slight outward movement thereof when a plug pin is inserted therein, and wherein said collet extends slightly forward of said retainer and said forwardly disposed means bears against the forward end of the retainer and encloses the projecting portions of the prongs extending therefrom.

Claim 12

A pacer connector arrangement for connecting an electrode plug pin to a pacer circuit comprising a connector assembly for coupling signals between the pacer circuit and the plug pin, said connector assembly having a multi-pronged collet embedded in the pacer, each prong thereof having a ridge projecting toward the central axis of the collet with the radial spacings of the ridges being such that when a pin is inserted therebetween the prongs are forced slightly outwardly, means disposed forward of said multi-pronged collet for guiding a pin inserted therethrough along the axis of said collet and for effecting a water-tight seal with said plug, said collet and said forwardly disposed means being contained at the rear of a receptacle in the pacer into which said plug is insertable, means for mechanically locking said plug in said receptacle, a retainer disposed around said multi-pronged collet, the rear of said collet being fixed to the rear of said retainer, said retainer providing clearance around the retained collet prongs for allowing slight outward movement thereof when a plug pin is inserted therein, and wherein said collet extends slightly forward of said retainer and said forwardly disposed means bears against the forward end of the retainer and encloses the projecting portions of the prongs extending therefrom.
