ABSTRACT:
An electrical medical connector having an integrally formed conductive pad including several flexible fingers defined by several radial slots. Each contact finger is flexible radially outward into a conforming recess when a male conductive stud from a contact pad is inserted within the connector. Each flexible finger engages a narrowed portion of the male stud to form a conductive path at a first contact region, wherein a surface of each contact finger engages collar portion of the male stud to provide a second contact region. Due to the redundancy of the first and second contact regions, damage, loss or wear of one contact finger does not result in degraded electrical contact between the connector and the stud, hence, a more reliable connector is established. The conductive pad formed in insulating connector body includes an integrally formed crimp finger which is crimped to a conducting wire. The connecting wire typically is routed to a medical device such as an electrocardiograph. Because the crimp finger is integrally formed with the conductive pad, time-consuming soldering or welding between the two is avoided to provide an improved and more reliable physical and electrical connection. The radial fingers which are biased toward the received male stud provide an increased bite against the male stud in contrast to two tangent contacting surfaces to reduce the effects of worn or dirty surface areas.
