A one-piece tubular snap-in electrical connector for connecting electrical cables to junction boxes. The connector is formed from an elastic material and includes tangs projecting outwardly from the tubular body which function to lock the forward end in a junction box and cause the connector to be grounded to the junction box. Inward projecting tangs on the opposite end of the connector are spaced to anchor successive helixes on a helically-wound cable. The ends of the inward projecting tangs force an inserted cable to be channeled against one inner wall of the tubular body and resist rearward movement of the cable once it is thus inserted.

Junction block bracket for floating connector attachment
An apparatus for securing wire harness terminal connectors to the underside of an electrical junction block in a blind assembly operation. The apparatus includes a flotation bracket with chambers for receiving the connectors in a mechanical snap-fit in which the connectors are free to float up and down over a limited range within their respective chambers. The connector-containing bracket is next placed in a lower cover, which then fits over the underside of the junction block. Bolts rotatably mounted in the junction block are located to automatically engage captive nuts held in the connectors. As the bolts are subsequently threaded through the captive nuts, the connectors are drawn up in the bracket chambers from a lower rest position to an upper electrical engagement position where the terminals in the connector are placed in electrical engagement with bus bars in the junction block. Upper stops in the chambers prevent the connectors from moving beyond the electrical engagement position and damaging parts of the junction block, bus bars, connectors and terminals.
