Abstract

A heart pacer connector assembly for two bipolar electrode lead proximal terminations, each having a forward pin contact and a rearward annular ring contact. Two in-line pairs of metallic termination blocks are connected by four wires to respective lead-through terminals. At least two fluid-insulating, metal-free plastic parts (molded without embedding termination blocks in them) are then slid on the assembly to insulate the termination blocks and to provide a pair of insertion bores for the proximal terminations. The plastic parts are shaped to lock onto capped studs provided on the case, and the plastic parts are sealed to each other. Each termination block for an annular ring contact may consist of a simple hollow cylinder having three equally spaced circumferential cuts, with a contact wire being wrapped around the cylinder, sitting in the cuts and extending into the cylinder bore, and being connected directly to the respective terminal.
