  • Resilient connector having an insertable stop member
    Patent number: 5879204
    Abstract: A resilient connector for maintaining an electrical conductor in side-by-side conductive engagement with a bus bar includes a generally loop- or O-shaped resilient contact body having a first end portion, an intermediate portion arranged generally normal to the intermediate portion, and a second end portion that is normally arranged at an acute angle relative to the contact intermediate portion, the contact first end portion containing a window opening having first and second opposed edges remote from and adjacent the intermediate portion, respectively, the second contact end portion being displaceable from a normal first position adjacent the first window edge toward a second position adjacent the second window edge, whereby when the second contact end is displaced to its second position and a conductor and a bus bar are introduced in side-by-side electrically conductive relation within the window, release of the second end portion causes the conductor and the bus bar to be clamped in tight electrical contac
