ABSTRACT:
A multi-part molded pacemaker connector meets the precise requirements imposed by the VS-1 standard, yet does not require complex nor expensive machining of individual parts. The connector includes a molded body tip and a molded body ring, adapted to be joined together during assembly. The body tip is molded to include a conductive connector block attached to a first conductive ribbon as an integral part thereof. The body ring is molded to include a second conductive ribbon, having a looped end exposed therewithin to provide a precise specified diameter against which a garter spring contact is placed. An inner shoulder molded within the body ring holds the spring contact laterally on one side. During assembly, an annular spacer is pressed into the body ring to restrain the spring contact laterally on the other side. Inner and outer annular seals are also inserted into the body tip and body ring during assembly. After assembly, i.e., after joining the body tip to the body ring, the connector may be pretested for leakage, dimensionality and conductivity prior to casting it in epoxy as part of the pacemaker connector top.
