Abstract:
1. A connector head for coupling a lead to a generator body, the connector head comprising: at least one housing for receiving a plug end of a lead along an axis of insertion; an elastic element configured to receive and immobilize the plug in the housing, wherein the elastic element comprises a U-shaped leaf spring having a first branch and a second branch, the first and second branches having respective first and second holes that allow the plug to be inserted through the first and second holes in the housing; wherein the U-shaped leaf spring is deformable between a free state, wherein the leaf spring is in a neutral position, and a deformed state, wherein the leaf spring takes on an expanded position; wherein in the free state, the projections of the first and second holes in a plane perpendicular to the axis of insertion are misaligned; wherein in the deformed state the projections of the first and second holes in the plane perpendicular to the axis of insertion are sufficiently aligned to receive an inserted plug so that an edge of each of the first and second holes contact the plug inserted therein and exert a radial stress force against the plug, producing a retaining force against extraction of the plug in a direction opposite to the insertion; and wherein the elastic element further comprises a release mechanism configured to receive an external force on the elastic element to neutralize said retaining force and thereby permit a removal of the plug from the housing; wherein the release mechanism is a flange at a free end of one of the first branch and the second branch of the U-shaped leaf spring, extending in a plane substantially parallel to the axis of insertion.
