ABSTRACT:
A tubular electrical connector having first and second tubular contact members spaced from one another to establish a gap between them and joined in a unitary structure by a strap unitary with corresponding wall portions of the tubular contact members and bridging the gap, a contact bar bridging the gap and secured in each tubular contact member, and a clamping screw for securing a conductor in each tubular contact member against the contact bar. The gap receives a complementary projection on a terminal block to locate and secure the connector in a terminal block assembly. The connector is fabricated by providing and then bending a metal blank along prescribed boundaries, welding along confronting edges, subsequent to bending, and then locating and securing the contact bar in place.
