Title: CONNECTOR ASSEMBLY WITH CONTACT RINGS COMPRISING BIASED BALL-SPRING CONTACTS
Abstract:
A connector assembly includes a connector housing having a longitudinal axis and a port for receiving a proximal end of a lead having terminals electrically insulated from one another. A lumen extends along the longitudinal axis of the connector housing. Contacts are disposed in the housing and are electrically insulated from one another. The contacts couple to the terminals when the proximal end of the lead is received within the lumen. Each contact (500) includes a contact ring and ball-spring assemblies (508) distributed around the contact ring. Each ball-spring assembly includes a housing coupled to the contact ring, a biasing member (514) disposed within the ball-spring housing and a conductive ball disposed at least partially within the ball-spring housing. The ball-spring housing defines an opening that is smaller than a diameter of the ball and the biasing member is configured to urge the ball towards the opening so that a portion of the ball extends out of the opening in the ball-spring housing.
