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.
