Abstract:
1. An electrical connection device for transmitting high current levels comprising: a contact blade including a blade thickness; a tulip contact including: an upper spring including a plurality of pairs of spring fingers, each pair of spring fingers including a first spring finger that is opposed to and spaced apart from a second spring finger, the first and the second spring fingers extend toward each other at a second angle, the first and the second spring fingers each include a second length; wherein the tulip contact is seated within the upper spring and each pair of contact fingers is between a different pair of spring fingers, the spring fingers apply contact force to the contact fingers to compress the first and second contact fingers together and compress each pair of contact fingers against the contact blade; wherein the second angle is greater than the first angle; wherein the first length is greater than the second length; and wherein contact between the contact fingers and the contact blade is operable to permit transmission of current greater than 80 amperes; wherein the tulip contact includes at least three pairs of contact fingers; wherein the upper spring includes a housing and at least three pairs of spring fingers; wherein push-through protection is connected between the pairs of contact fingers; and wherein each of the contact fingers are longer than each of the spring fingers.
