ABSTRACT:
An antishock, insulated connector of the type adapted to be electrically coupled to a heart pulse generator is disclosed as comprising an electrically conductive lead coupled to a pin, and a layer of insulating material disposed about the lead and the pin. A further, electrically conductive element is disposed about the insulating layer in an electrically isolated position with respect to the pin and is adapted upon insertion into a female receptacle to be brought into electrical contact with the pin, whereby a circuit is completed through the electrically conductive element, the pin and the lead. In one illustrative embodiment the electrically conductive element comprises a tube-like metallic ring spaced from the pin by a pair of spacers made of an electrically insulating, elastic material and disposed between the pin and the ring, whereby upon application of an offsetting pressure to the metallic ring, the metallic ring is directed toward the pin and the elastic material is compressed so that electrical contact is made between the ring and the pin. In a further embodiment of this invention, the electrically conductive element takes the form of an electrically conductive reed-like member suspended at one end with the other end embedded in an elastomer to be flexed into electrical contact with its electrically conductive pin.
