US 9,312,610 B2 · Stepped spring contact

Abstract

In an embodiment, a stepped spring contact may have a first portion, a transition portion, and a second portion. The first portion may include a plurality of windings whose pitch may vary. The second portion may include a plurality of windings that are closely wound. A pitch of the windings contained in the second portion may be, for example, constant. The transition portion may include a winding that may make mechanical and electrical contact with a first electrical conductor (e.g., a pad contained on a printed circuit board (PCB)). The first portion may include a tip. The tip may be, for example, flat shaped or conically shaped. The tip may make electrical contact with a second electrical conductor (e.g., a terminal connector). In operation, the stepped spring contact may provide electrical continuity between the first electrical conductor and the second electrical conductor.
